    This research investigates the indirect effects of religiosity (practice and belief) on therapeutic compliance in 81 HIV-positive patients who are migrants from sub-Saharan Africa (23 men and 58 women). Using analyses of mediation and standard multiple regression, including a resampling procedure by bootstrapping, the role of these mediators (magical-religious beliefs and nonuse of toxic substances) was tested. The results show that, through magical-religious beliefs, religiosity has a negative indirect effect, while with the nonuse of toxic substances, religious practice has a positive indirect effect. Beyond religiosity, the role of mediators is highlighted in the interaction with therapeutic compliance.

    2016-12-01

    The perception of a direct gaze - that is, of another individual's gaze directed at the observer that leads to eye contact - is known to influence a wide range of cognitive processes and behaviors. We stress that these effects mainly reflect positive impacts on human cognition and may thus be used as relevant tools for therapeutic purposes. In this review, we aim (1) to provide an exhaustive review of eye contact effects while discussing the limits of the dominant models used to explain these effects, (2) to illustrate the therapeutic potential of eye contact by targeting those pathologies that show both preserved gaze processing and deficits in one or several functions that are targeted by the eye contact effects, and (3) to propose concrete ways in which eye contact could be employed as a therapeutic tool. (1) We regroup the variety of eye contact effects into four categories, including memory effects, activation of prosocial behavior, positive appraisals of self and others and the enhancement of self-awareness. We emphasize that the models proposed to account for these effects have a poor predictive value and that further descriptions of these effects is needed. (2) We then emphasize that people with pathologies that affect memory, social behavior, and self and/or other appraisal, and self-awareness could benefit from eye contact effects. We focus on depression, autism and Alzheimer's disease to illustrate our proposal. To our knowledge, no anomaly of eye contact has been reported in depression. Patients suffering from Alzheimer disease, at the early and moderate stage, have been shown to maintain a normal amount of eye contact with their interlocutor. We take into account that autism is controversial regarding whether gaze processing is preserved or altered. In the first view, individuals are thought to elude or omit gazing at another's eyes while in the second, individuals are considered to not be able to process the gaze of others. We adopt the first stance

    Idiopathic inflammatory myopathies are a group of clinically heterogeneous diseases, which have been classified by myositis specific antibodies recently. The anti-SRP positive subset of this group is characterized by more severe clinical prognosis than other myositis specific antibody positive types. Our goal was to compare 16 anti-SRP positive patients in the Division of Clinical Immunology, Department of Internal Medicine, University of Debrecen with 16 antibody negative ones. Muscle strength validated in both groups by the manual muscle test proved to be significantly decreased both before and after therapy (χ 2 = 0.006 and 0.019) in the anti-SRP positive group. Muscle-specific inflammatory laboratory parameters showed significant difference only in case of LDH-levels after therapy. Both groups showed good clinical response to first line steroid treatment, yet the significantly higher rate of second line administration suggests worse therapeutic response of the antibody positive group. Based on these facts we determined poor clinical prognosis and therapeutic response of the anti-SRP positive group. Orv Hetil. 2017; 158(35): 1382-1389.

  5. Developments in stem cell research and therapeutic cloning: Islamic ethical positions, a review.

    Stem cell research is very promising. The use of human embryos has been confronted with objections based on ethical and religious positions. The recent production of reprogrammed adult (induced pluripotent) cells does not - in the opinion of scientists - reduce the need to continue human embryonic stem cell research. So the debate continues. Islam always encouraged scientific research, particularly research directed toward finding cures for human disease. Based on the expectation of potential benefits, Islamic teachings permit and support human embryonic stem cell research. The majority of Muslim scholars also support therapeutic cloning. This permissibility is conditional on the use of supernumerary early pre-embryos which are obtained during infertility treatment in vitro fertilization (IVF) clinics. The early pre-embryos are considered in Islamic jurisprudence as worthy of respect but do not have the full sanctity offered to the embryo after implantation in the uterus and especially after ensoulment. In this paper the Islamic positions regarding human embryonic stem cell research and therapeutic cloning are reviewed in some detail, whereas positions in other religious traditions are mentioned only briefly. The status of human embryonic stem cell research and therapeutic cloning in different countries, including the USA and especially in Muslim countries, is discussed. © 2010 Blackwell Publishing Ltd.

    To better understand how Therapeutic Touch can be used in today's health care arena, this integrative literature review will examine current research that will help answer the question, Does Therapeutic Touch reduce pain? An extensive search was conducted of the online databases MEDLINE, CINAHL, Cochrane Library, EMBASE, PsychLIT, and PubMed to retrieve research articles published from 1997 to 2007. Seven studies that were conducted between 1997 and 2004 were found and only five of the seven were included as pertinent evidence to answer the question. All of the research that was reviewed to answer whether Therapeutic Touch could significantly reduce pain revealed a majority of statistically significant positive results for implementing this intervention. Because there are no identified risks to Therapeutic Touch as a pain relief measure, it is safe to recommend despite the limitations of current research. Therapeutic Touch should be considered among the many possible nursing interventions for the treatment of pain.

    Extracellular vesicles (EVs), such as exosomes and microvesicles, are released by different cell types and participate in physiological and pathophysiological processes. EVs mediate intercellular communication as cell-derived extracellular signalling organelles that transmit specific information from their cell of origin to their target cells. As a result of these properties, EVs of defined cell types may serve as novel tools for various therapeutic approaches, including (a) anti-tumour therapy, (b) pathogen vaccination, (c) immune-modulatory and regenerative therapies and (d) drug delivery. The translation of EVs into clinical therapies requires the categorization of EV-based therapeutics in compliance with existing regulatory frameworks. As the classification defines subsequent requirements for manufacturing, quality control and clinical investigation, it is of major importance to define whether EVs are considered the active drug components or primarily serve as drug delivery vehicles. For an effective and particularly safe translation of EV-based therapies into clinical practice, a high level of cooperation between researchers, clinicians and competent authorities is essential. In this position statement, basic and clinical scientists, as members of the International Society for Extracellular Vesicles (ISEV) and of the European Cooperation in Science and Technology (COST) program of the European Union, namely European Network on Microvesicles and Exosomes in Health and Disease (ME-HaD), summarize recent developments and the current knowledge of EV-based therapies. Aspects of safety and regulatory requirements that must be considered for pharmaceutical manufacturing and clinical application are highlighted. Production and quality control processes are discussed. Strategies to promote the therapeutic application of EVs in future clinical studies are addressed. PMID:26725829

    To evaluate the effectiveness of barium impaction therapy for patients with colonic diverticular bleeding. We reviewed the clinical charts of patients in whom therapeutic barium enema was performed for the control of diverticular bleeding between August 2010 and March 2012 at Yokohama Rosai Hospital. Twenty patients were included in the review, consisting of 14 men and 6 women. The median age of the patients was 73.5 years. The duration of the follow-up period ranged from 1 to 19 mo (median: 9.8 mo). Among the 20 patients were 11 patients who required the procedure for re-bleeding during hospitalization, 6 patients who required it for re-bleeding that developed after the patient left the hospital, and 3 patients who required the procedure for the prevention of re-bleeding. Barium (concentration: 150 w%/v%) was administered per the rectum, and the leading edge of the contrast medium was followed up to the cecum by fluoroscopy. After confirmation that the ascending colon and cecum were filled with barium, the enema tube was withdrawn, and the patient's position was changed every 20 min for 3 h. Twelve patients remained free of re-bleeding during the follow-up period (range: 1-19 mo) after the therapeutic barium enema, including 9 men and 3 women with a median age of 72.0 years. Re-bleeding occurred in 8 patients including 5 men and 3 women with a median age of 68.5 years: 4 developed early re-bleeding, defined as re-bleeding that occurs within one week after the procedure, and the remaining 4 developed late re-bleeding. The DFI (disease-free interval) decreased 0.4 for 12 mo. Only one patient developed a complication from therapeutic barium enema (colonic perforation). Therapeutic barium enema is effective for the control of diverticular hemorrhage in cases where the active bleeding site cannot be identified by colonoscopy.

    Equine-assisted therapies, such as therapeutic riding and hippotherapy, are believed to have positive physical and emotional effects in individuals with neuromotor, developmental, and physical disabilities. The purpose of this review was to determine whether therapeutic riding and hippotherapy improve balance, motor function, gait, muscle symmetry, pelvic movement, psychosocial parameters, and the patients' overall quality of life. In this study, a literature search was conducted on MEDLINE, CINAHL, MBASE, SportDiscus, Cochrane Database of Systematic Reviews, Cochrane Controlled Trials Register, PEDro, DARE, Google Scholar, and Dissertation Abstracts. Only studies with a control/comparison group or self-controlled studies performing preintervention and postintervention assessment were included. Excluded were (1) studies not providing data on baseline score or end-point outcome, (2) single-subject studies, (3) studies providing only qualitative data, and (4) studies that used a mechanical horse. Sixteen trials were included. The methodologic quality of each study was evaluated using Downs and Black quality assessment tool. Most of the studies showed a trend toward a beneficial effect of therapeutic riding and hippotherapy on balance and gross motor function. The meta-analysis showed improvement in both the Berg Balance Scale and the Gross Motor Function Measure in therapeutic riding and hippotherapy programs. Programs such as therapeutic riding and hippotherapy are a viable intervention option for patients with balance, gait, and psychomotor disorders.

    The therapeutic effect of cefozopran (SCE-2787), a new semisynthetic parenteral cephalosporin, against experimental infections in mice was examined. Cefozopran was more effective than cefpiramide and was as effective as ceftazidime and cefpirome against acute respiratory tract infections caused by Klebsiella pneumoniae DT-S. In the model of chronic respiratory tract infection caused by K. pneumoniae 27, cefozopran was as effective as ceftazidime. The therapeutic effect of cefozopran against urinary tract infections caused by Pseudomonas aeruginosa P9 was superior to that of cefpirome and was equal to those of ceftazidime and cefclidin. In addition, cefozopran was more effective than ceftazidime and was as effective as flomoxef in a thigh muscle infection caused by methicillin-sensitive Staphylococcus aureus 308A-1. Against thigh muscle infections caused by methicillin-resistant S. aureus N133, cefozopran was the most effective agent. The potent therapeutic effect of cefozopran in those experimental infections in mice suggests that it would be effective against respiratory tract, urinary tract, and soft tissue infections caused by a variety of gram-positive and gram-negative bacteria in humans.

    Statins and sartans can, in therapeutic doses, induce pleiotropic cardiovascular effects. Similar has recently been shown also for sub-therapeutic doses. We thus explored and compared the cardiovascular pleiotropic efficacy of sub-therapeutic vs. therapeutic doses. Wistar rats were randomly divided into 7 groups receiving fluvastatin, valsartan and their combination in sub-therapeutic and therapeutic doses, or saline. After 6weeks, the animals were euthanised, their hearts and thoracic aortas isolated, and blood samples taken. Endothelium-dependent relaxation of the thoracic aortae and ischaemic-reperfusion injury of the isolated hearts were assessed along with the related serum parameters and genes expression. Fluvastatin and valsartan alone or in combination were significantly more effective in sub-therapeutic than therapeutic doses. The sub-therapeutic combination greatly increased thoracic aorta endothelium-dependent relaxation and maximally protected the isolated hearts against ischaemia-reperfusion injury and was thus most effective. Beneficial effects were accompanied by increased levels of nitric oxide (NO) and decreased levels of asymmetric dimethylarginine (ADMA) in the serum (again prominently induced by the sub-therapeutic combination). Furthermore, nitric oxide synthase 3 (NOS3) and endothelin receptor type A (EDNRA) genes expression increased, but only in both combination groups and without significant differences between them. In the therapeutic dose groups, fluvastatin and valsartan decreased cholesterol values and systolic blood pressure. Sub-therapeutic doses of fluvastatin and valsartan are more effective in expressing cardiovascular pleiotropic effects than therapeutic doses of fluvastatin and/or valsartan. These results could be of significant clinical relevance. Copyright © 2017 Elsevier Inc. All rights reserved.

  14. Nonthermal effects of therapeutic ultrasound: the frequency resonance hypothesis.

    Johns, Lennart D

    2002-07-01

    To present the frequency resonance hypothesis, a possible mechanical mechanism by which treatment with non-thermal levels of ultrasound stimulates therapeutic effects. The review encompasses a 4-decade history but focuses on recent reports describing the effects of nonthermal therapeutic levels of ultrasound at the cellular and molecular levels. A search of MEDLINE from 1965 through 2000 using the terms ultrasound and therapeutic ultrasound. The literature provides a number of examples in which exposure of cells to therapeutic ultrasound under nonthermal conditions modified cellular functions. Nonthermal levels of ultrasound are reported to modulate membrane properties, alter cellular proliferation, and produce increases in proteins associated with inflammation and injury repair. Combined, these data suggest that nonthermal effects of therapeutic ultrasound can modify the inflammatory response. The concept of the absorption of ultrasonic energy by enzymatic proteins leading to changes in the enzymes activity is not novel. However, recent reports demonstrating that ultrasound affects enzyme activity and possibly gene regulation provide sufficient data to present a probable molecular mechanism of ultrasound's nonthermal therapeutic action. The frequency resonance hypothesis describes 2 possible biological mechanisms that may alter protein function as a result of the absorption of ultrasonic energy. First, absorption of mechanical energy by a protein may produce a transient conformational shift (modifying the 3-dimensional structure) and alter the protein's functional activity. Second, the resonance or shearing properties of the wave (or both) may dissociate a multimolecular complex, thereby disrupting the complex's function. This review focuses on recent studies that have reported cellular and molecular effects of therapeutic ultrasound and presents a mechanical mechanism that may lead to a better understanding of how the nonthermal effects of ultrasound may be

    Full Text Available Introduction. Undiagnosed and untreated syphilis in pregnancy may result in subsequent complications: early fetal loss, stillbirth, low birth weight of infants and newborns with congenital syphilis. Objective. To analyze diagnostic and therapeutic dilemmas of positive results of serological tests for syphilis (STS in pregnancy. Case reports. We present two cases of pregnant women, hospitalized in our department due to positive results of serological tests for syphilis, performed during the antenatal visit. On the basis of patients' history, physical examination and STS results, early latent syphilis was diagnosed in the first patient; biological false positive reactions were considered in the second one. Both patients received procaine penicillin treatment. Conclusions. Screening for syphilis in pregnancy as a part of antenatal care and appropriate treatment with penicillin are the most effective interventions to prevent complications of syphilis in pregnancy. It is also important to adapt modern European Guidelines for management of syphilis to Polish conditions.

  17. Therapeutic Potential of a Scorpion Venom-Derived Antimicrobial Peptide and Its Homologs Against Antibiotic-Resistant Gram-Positive Bacteria

    Gaomin Liu

    2018-05-01

    Full Text Available The alarming rise in the prevalence of antibiotic resistance among pathogenic bacteria poses a unique challenge for the development of effective therapeutic agents. Antimicrobial peptides (AMPs have attracted a great deal of attention as a possible solution to the increasing problem of antibiotic-resistant bacteria. Marcin-18 was identified from the scorpion Mesobuthus martensii at both DNA and protein levels. The genomic sequence revealed that the marcin-18 coding gene contains a phase-I intron with a GT-AG splice junction located in the DNA region encoding the N-terminal part of signal peptide. The peptide marcin-18 was also isolated from scorpion venom. A protein sequence homology search revealed that marcin-18 shares extremely high sequence identity to the AMPs meucin-18 and megicin-18. In vitro, chemically synthetic marcin-18 and its homologs (meucin-18 and megicin-18 showed highly potent inhibitory activity against Gram-positive bacteria, including some clinical antibiotic-resistant strains. Importantly, in a mouse acute peritonitis model, these peptides significantly decreased the bacterial load in ascites and rescued nearly all mice heavily infected with clinical methicillin-resistant Staphylococcus aureus from lethal bacteremia. Peptides exerted antimicrobial activity via a bactericidal mechanism and killed bacteria through membrane disruption. Taken together, marcin-18 and its homologs have potential for development as therapeutic agents for treating antibiotic-resistant, Gram-positive bacterial infections.

    The role of occlusion concerning temporomandibular disorder is still unclear but seems to be the only component of the stomathognathic system dentists are able to change morphologically. The aim of the paper is to describe the orthodontist's approach for transferring and maintaining a therapeutic splint position into permanent occlusion using a fully customized lingual appliance. Fixed acrylic bite planes on lower molars were used to maintain a symptom-free condyle position prior to orthodontic treatment. Silicone impressions of the arches including the fixed bite planes were used for the Incognito laboratory procedure. Two digital setups were made. One setup represents the target occlusion. A second setup including the bite planes was used to fabricate an additional set of lower molar brackets. In the leveling stage all teeth except the lower molars were settled to maintain the therapeutic condyle position. Finally, the fixed bite planes were stepwise removed and molar brackets were replaced to establish the permanent occlusion planned with the first setup. The advantage of an individual lingual appliance consists in the high level of congruence between the fabricated setups and the final clinical result. Both the individual scope for design and the precision of the appliance were vitally important in the treatment of a patient with a functional disorder of the masticatory system.

    Transplantation of human mesenchymal multipotent stromal cells improved spatial memory in bulbectomized mice with Alzheimer-type neurodegeneration. The positive effect was observed in 1 month after intracerebral transplantation and in 3 months after systemic injection of mesenchymal multipotent stromal cells. No cases of malignant transformation were noted. These findings indicate prospects of using mesenchymal multipotent stromal cells for the therapy of Alzheimer disease and the possibility of their systemic administration for attaining the therapeutic effect.

    Full Text Available Several treatment evaluations have highlighted the effectiveness of cognitive-behavioural programmes with both youth and adult offenders. This paper describes the application and assessment of a cognitive-behavioural treatment (adapted to Spanish from Ross and Fabiano’s Reasoning & Rehabilitation Programme with juvenile offenders serving community orders in an educational measure called in Spanish ‘libertad vigilada’ (similar to parole. The intervention comprised six different therapeutic components: self-control, cognitive restructuring, problem solving, social skills/assertiveness, values/empathy, and relapse prevention. Treatment effectiveness was tested using a quasi-experimental design involving two groups and pre/post evaluation. The results show that the programme was effective (with low to moderate effect sizes in improving participants’ social skills and self-esteem, as well as in reducing their aggressiveness. However, the intervention had no positive influence on empathy, cognitive distortions or impulsiveness. These results are in line with those of many other correctional studies, in which the treatment applied had a significant but partial effect on participants.

    The use of complementary and alternative medicine (CAM) techniques has been growing. The National Center for Complementary and Alternative Medicine places therapeutic touch (TT) into the category of bio field energy. This literature review is aimed at critically evaluating the data from clinical trials examining the clinical efficacy of therapeutic touch as a supportive care modality in adult patients with cancer. Electronic databases (PubMed, Scopus, Scholar Google, and Science Direct) were searched from the year 1990 to 2015 to locate potentially relevant peer-reviewed articles using the key words therapeutic touch, touch therapy, neoplasm, cancer, and CAM. Additionally, relevant journals and references of all the located articles were manually searched for other potentially relevant studies. The number of 334 articles was found on the basis of the key words, of which 17 articles related to the clinical trial were examined in accordance with the objectives of the study. A total of 6 articles were in the final dataset in which several examples of the positive effects of healing touch on pain, nausea, anxiety and fatigue, and life quality and also on biochemical parameters were observed. Based on the results of this study, an affirmation can be made regarding the use of TT, as a non-invasive intervention for improving the health status in patients with cancer. Moreover, therapeutic touch was proved to be a useful strategy for adult patients with cancer.

    Full Text Available Abstract Introduction The role of occlusion concerning temporomandibular disorder is still unclear but seems to be the only component of the stomathognathic system dentists are able to change morphologically. The aim of the paper is to describe the orthodontist’s approach for transferring and maintaining a therapeutic splint position into permanent occlusion using a fully customized lingual appliance. Methods Fixed acrylic bite planes on lower molars were used to maintain a symptom-free condyle position prior to orthodontic treatment. Silicone impressions of the arches including the fixed bite planes were used for the Incognito laboratory procedure. Two digital setups were made. One setup represents the target occlusion. A second setup including the bite planes was used to fabricate an additional set of lower molar brackets. In the leveling stage all teeth except the lower molars were settled to maintain the therapeutic condyle position. Finally, the fixed bite planes were stepwise removed and molar brackets were replaced to establish the permanent occlusion planned with the first setup. Results and discussion The advantage of an individual lingual appliance consists in the high level of congruence between the fabricated setups and the final clinical result. Both the individual scope for design and the precision of the appliance were vitally important in the treatment of a patient with a functional disorder of the masticatory system.

    The present study aimed to examine the therapeutic effects of Islamic intercessory prayer on warts. Forty-five participants who are mostly Muslims and infected with warts were randomized into three groups: Group-1 (uncertain, with intercessory prayer), Group-2 (uncertain, no intercessory prayer), and control group (informed, no intervention). Stress symptoms were also measured before and after prayer sessions for these three groups. The results revealed that there were no significant differences between the groups in terms of healing. Although participants believed in the therapeutic effects of prayer, when participants did not trust the intercessor, prayer had no effect on warts.

    Part 1 of this position statement dealt with the assessment of male hypogonadism, including the indications for testosterone therapy. This article, Part 2, focuses on treatment and therapeutic considerations for male hypogonadism and identifies key questions for future research. Key points and recommendations are:Excess cardiovascular events have been reported in some but not all studies of older men without pathological hypogonadism who were given testosterone treatment. Additional studies are needed to clarify whether testosterone therapy influences cardiovascular risk.Testosterone is the native hormone that should be replaced in men being treated for pathological hypogonadism. Convenient and cost-effective treatment modalities include depot intramuscular injection and transdermal administration (gel, cream or liquid formulations).Monitoring of testosterone therapy is recommended for efficacy and safety, focusing on ameliorating symptoms, restoring virilisation, avoiding polycythaemia and maintaining or improving bone mineral density.Treatment aims to relieve an individual's symptoms and signs of androgen deficiency by administering standard doses and maintaining circulating testosterone levels within the reference interval for eugonadal men.Evaluation for cardiovascular disease and prostate cancer risks should be undertaken as appropriate for eugonadal men of similar age. Nevertheless, when there is a reasonable possibility of substantive pre-existing prostate disease, digital rectal examination and prostate-specific antigen testing should be performed before commencing testosterone treatment.Changes in management as result of the position statement: Treatment aims to relieve symptoms and signs of androgen deficiency, using convenient and effective formulations of testosterone. Therapy should be monitored for efficacy and safety.

  7. Potential Therapeutic Effects of Psilocybin.

    Psilocybin and other 5-hydroxytryptamine 2A agonist classic psychedelics have been used for centuries as sacraments within indigenous cultures. In the mid-twentieth century they were a focus within psychiatry as both probes of brain function and experimental therapeutics. By the late 1960s and early 1970s these scientific inquires fell out of favor because classic psychedelics were being used outside of medical research and in association with the emerging counter culture. However, in the twenty-first century, scientific interest in classic psychedelics has returned and grown as a result of several promising studies, validating earlier research. Here, we review therapeutic research on psilocybin, the classic psychedelic that has been the focus of most recent research. For mood and anxiety disorders, three controlled trials have suggested that psilocybin may decrease symptoms of depression and anxiety in the context of cancer-related psychiatric distress for at least 6 months following a single acute administration. A small, open-label study in patients with treatment-resistant depression showed reductions in depression and anxiety symptoms 3 months after two acute doses. For addiction, small, open-label pilot studies have shown promising success rates for both tobacco and alcohol addiction. Safety data from these various trials, which involve careful screening, preparation, monitoring, and follow-up, indicate the absence of severe drug-related adverse reactions. Modest drug-related adverse effects at the time of medication administration are readily managed. US federal funding has yet to support therapeutic psilocybin research, although such support will be important to thoroughly investigate efficacy, safety, and therapeutic mechanisms.

    Two linked randomized field trials were performed on 39 herds in the Netherlands to 1) determine therapeutic effects of antimicrobial treatment of recently acquired subclinical mastitis (RASCM) during lactation, 2) evaluate the effect of duration of subclinical mastitis on therapeutic outcome, and 3) identify factors related to the therapeutic success of RASCM. Cows with a first elevated composite somatic cell count (CSCC) after 2 consecutive low CSCC measurements were eligible for enrollment in trial 1 (treatment at the first elevated CSCC). Quarter milk samples were collected to determine bacteriological status for major pathogens and coagulase-negative staphylococci. Cows with one or more culture-positive quarters with a quarter somatic cell count (QSCC) >or=100,000 cells/mL were defined to have RASCM and were randomly assigned treatment or control (no treatment). Untreated cows from trial 1 that had a second elevated CSCC at the next milk recording were eligible for enrollment in trial 2 (treatment at the second elevated CSCC). In trial 2, staphylococci-positive cows (Staphylococcus aureus and coagulase-negative staphylococci) were randomly assigned to treatment or control. Farmers used their own treatment protocols to treat quarters in both trials. Bacteriological cure was defined as absence of the pathogen identified pre-intervention in 2 samples post-intervention; QSCC, CSCC, and milk yield were also analyzed. Hierarchical logistic and linear models were used to determine therapeutic effects and to identify factors related to therapy outcome. Treated quarters had a higher bacteriological cure rate than control quarters for all pathogens in both trials. Treatment resulted in lower QSCC and CSCC, whereas milk yield was not affected by treatment. Bacteriological cure of RASCM was better in quarters with a low QSCC pre-intervention and in coagulase-negative staphylococci-positive quarters. Control quarters with a single culture-positive sample pre

    2015-05-01

    The exploration of Mindfulness-based Cognitive Therapy through qualitative investigation is a growing area of interest within current literature, providing valuable understanding of the process of change experienced by those engaging in this therapeutic approach. This meta-synthesis aims to gain a deeper understanding of how the features of Mindfulness-based Cognitive Therapy contribute to positive therapeutic change. Noblit and Hare's (1988) 7-step meta-ethnography method was conducted in order to synthesize the findings of seven qualitative studies. The process of reciprocal translation identified the following five major themes: i) Taking control through understanding, awareness and acceptance; ii) The impact of the group; (iii) Taking skills into everyday life; (iv) Feelings towards the self; (v) The role of expectations. The synthesis of translation identified the higher order concept of "The Mindfulness-based Cognitive Therapy Journey to Change", which depicts the complex interaction between the five themes in relation to how they contribute to positive therapeutic change. The findings are discussed in relation to previous research, theory and their implications for clinical practice.

    To assess the effect and importance of the therapeutic class of a drug as a determinant for verbal counseling by community pharmacists. Direct external observations (n = 1431) of pharmacist-customer interactions at the point of delivery of prescription medicines were conducted in 7 community pharmacies in Finland. Trained observers noted whether the pharmacist provided information on directions for use, mode of action, and adverse effects. To examine factors associated with counseling, a multiple logistic regression analysis was constructed, with the dependent variable being counseling of any of the 3 observed topics. In addition to therapeutic class, other independent variables were the pharmacy; pharmacist's age, gender, and degree; and the customer's age, gender, previous use of medicine, and question asking. Provision of counseling differed significantly according to therapeutic classes. Counseling on any of the 3 observed topics was most likely to be provided for customers with antibiotics (80%) and least likely for customers with gynecologic preparations (18%). Differences between therapeutic classes remained statistically significant when the effects of the other variables were controlled for. Other significant predictors for any verbal counseling were the pharmacy, customer's previous use of the medicine, and question asking. Therapeutic class is an important variable that should be included in further studies and considered when comparing studies on patient counseling in community pharmacies.

    Most antibiotics obtained by in vitro screening with antibacterial activity have inappropriate properties as medicines due to their toxicity and pharmacodynamics in animal bodies. Thus, evaluation of the therapeutic effects of these samples using animal models is essential in the crude stage. Mammals are not suitable for therapeutic evaluation of a large number of samples due to high costs and ethical issues. We propose the use of silkworms (Bombyx mori) as model animals for screening therapeutically effective antibiotics. Silkworms are infected by various pathogenic bacteria and are effectively treated with similar ED(50) values of clinically used antibiotics. Furthermore, the drug metabolism pathways, such as cytochrome P450 and conjugation systems, are similar between silkworms and mammals. Silkworms have many advantages compared with other infection models, such as their 1) low cost, 2) few associated ethical problems, 3) adequate body size for easily handling, and 4) easier separation of organs and hemolymph. These features of the silkworm allow for efficient screening of therapeutically effective antibiotics. In this review, we discuss the advantages of the silkworm model in the early stages of drug development and the screening results of some antibiotics using the silkworm infection model.

  14. Therapeutic effects of low radiation doses

    This editorial explores the scientific basis of radiotherapy with doses of < 1 Gy for various non-malignant conditions, in particular dose-effect relationships, risk-benefit considerations and biological mechanisms. A review of the literature, particularly clinical and experimental reports published more than 50 years ago was conducted to clarify the following problems. 1. The dose-response relationships for the therapeutic effects on three groups of conditions: non-malignant skin disease, arthrosis and other painful degenerative joint disorders and anti-inflammatory radiotherapy; 2. risks after radiotherapy and after the best alternative treatments; 3. the biological mechanisms of the different therapeutic effects. Radiotherapy is very effective in all three groups of disease. Few dose-finding studies have been performed, all demonstrating that the optimal doses are considerable lower than the generally recommended doses. In different conditions, risk-benefit analysis of radiotherapy versus the best alternative treatment yields very different results: whereas radiotherapy for acute postpartum mastitis may not be justified any more, the risk-benefit ratio of radiotherapy of other conditions and particularly so in dermatology and some anti-inflammatory radiotherapy appears to be more favourable than the risk-benefit ratio of the best alternative treatments. Radiotherapy can be very effective treatment for various non-malignant conditions such as eczema, psoriasis, periarthritis humeroscapularis, epicondylitis, knee arthrosis, hydradenitis, parotitis and panaritium and probably be associated with less acute and long-term side effects than similarly effective other treatments. Randomized clinical studies are required to find the optimal dosage which, at present, may be unnecessarily high.

    The incidence of chronic graft-versus-host disease (cGVHD) is rising recent years, which has been the leading cause of non-transplantation mortality post allogenetic hematopoietic stem cell transplantation (HSCT). Imbalance of inflammatory cytokines and fibrosis plays critical roles in the pathogenesis of cGVHD. Recent studies showed that molecular hydrogen has anti-inflammatory, antioxidant, anti-fibrosis effects. Therefore, we hypothesized that molecular hydrogen may have therapeutic effects on cGVHD. To determine whether hydrogen could protect mice from cGVHD in an MHC-incompatible murine bone marrow transplantation (BMT) model, survival rates of mice were calculated, and skin lesions were also evaluated after BMT. This article demonstrated that administration of hydrogen-rich saline increased survival rate of cGVHD mice. Administration of hydrogen-rich saline after transplantation also reduced skin lesions of cGVHD mice. Previously, we reported the therapeutic effects of hydrogen on acute GVHD. However, there was no report on the therapeutic effects of hydrogen on cGVHD mice. It is suggested that hydrogen has a potential as an effective and safe therapeutic agent on cGVHD. This study will provide new ideas on the treatment of cGVHD and has important theoretical values. © 2017 The Authors.

    Stark, Mary Ann

    : Therapeutic showering is a holistic nursing intervention that is often available and supports physiologic labor. The purpose of this study was to compare the effectiveness of therapeutic showering with usual care during active labor. Research questions were as follows: Are there significant differences between women who showered 30 minutes during active labor and those who received usual labor care in anxiety, tension, relaxation, pain, discomfort, and coping? Is there a difference in use of obstetric interventions between groups? A convenience sample of healthy low-risk women in active labor was recruited (N = 32). A pretest posttest control group repeated-measures design was used. Participants were randomized to treatment group (n = 17), who showered for 30 minutes, or to control group (n = 14) who received usual labor care. Women evaluated pain, discomfort, anxiety, tension, coping, and relaxation at enrollment, again 15 minutes after entering the shower or receiving usual care, then again 30 minutes after entering the shower or receiving usual care. Chart reviews after delivery recorded obstetric interventions. The showering group had statistically significant decreases in pain, discomfort, anxiety and tension, and significant increase in relaxation. There were no differences in use of obstetric interventions. Therapeutic showering was effective in reducing pain, discomfort, anxiety, and tension while improving relaxation and supporting labor in this sample.

    Many innovative approaches have attempted to challenge the dominant position of surgery, chemotherapy and radiotherapy as the major therapeutic modalities to treat cancer. However, only recently some new agents have appeared that achieve effects comparable to the ones of these established treatments. A novel class of such therapeutics consists of oncolytic viruses with several main representatives, namely adeno-, herpes, reo- and parvovirus. The latter class of anticancer agents has proven to be quite effective in many preclinical models and is now considered for a phase I clinical trial in patients with glioma and pancreatic cancer. An important question to be answered is whether virotherapy can be combined with standard treatments to achieve an enhanced antitumor effect still at a low level of toxicity. Here we present data concerning the application of irradiation together with H-1PV parvovirus infection comparing their toxic effects on normal and Ras -transformed fibroblasts. This proved to be a potent combination achieving high level of synergistic toxicity on transformed cells at doses, which did not affect the viability of normal human fibroblasts. This strategy holds promise to become a part of the clinical treatment of radioresistant tumours. (authors)

    Therapeutic success is characterized by undetectable viral load, immune reconstitution confirmed by CD4+ T-cell count and no clinical manifestations of disease. High treatment adherence is a major determinant of therapeutic success that needs prevention of viral replication, allowing immune reconstitution. Adherence to treatment minimum wage (IQR 1·0-2·3). Therapeutic success was achieved by 90% (122 patients), and it was associated with previously undetectable viral load (PR = 1·30; 95% CI = 1·13-1·49) and treatment adherence prior to study entry (PR = 1·34; 95% CI = 1·07-1·69), independently of sex, age and previous immune status. When undetectable viral load, CD4+ cell count ≥200 cells/mm(3) and treatment adherence above 95% are included in the definition of therapeutic success, the rate was elevated (90%) and the factors associated were previous history of adherence to HAART and previous undetectable viral load. © 2014 John Wiley & Sons Ltd.

    To examine the interaction effect of anxiety and depression on the intentional forgetting of positive and negative valence words. One hundred fifty-five grade 7 to grade 10 students participated in the study. The item-method directed forgetting paradigm was used to examine the intentional forgetting of positive-valence, negative-valence, and neutral-valence words. Negative-valence words were recognized better than either positive-valence or neutral-valence words. The results revealed an anxiety main effect (p = .01, LLCI = -.09, and ULCI = -.01) and a depression main effect (p = .04, LLCI = .00, and ULCI = .24). The anxiety score was negative, whereas the depression score was positively related to the directed forgetting of negative-valence words. Regression-based moderation analysis revealed a significant anxiety × depression interaction effect on the directed forgetting of positive-valence words (p = .02, LLCI = .00, and ULCI = .01). Greater anxiety was associated with more directed forgetting of positive-valance words only among participants with high depression scores. With negative-valence words, the anxiety × depression interaction effect was not significant (p = .15, LLCI = - .00, and ULCI = .01). Therapeutic strategies to increase positive memory bias may reduce anxiety symptoms only among those with high depression scores. Interventions to reduce negative memory bias may reduce anxiety symptoms irrespective of levels of depression. © 2018 Wiley Periodicals, Inc.

    To investigate the potential therapeutic effect of exopolysaccharide (EPS)-producing Streptococcus thermophilus (S. thermophilus) CRL 1190 fermented milk on chronic gastritis in Balb/c mice. Balb/c mice were fed with the fermented milk for 7 d after inducing gastritis with acetyl-salicylic acid (ASA, 400 mg/kg body weight per day for 10 d). Omeprazole was included in this study as a positive therapeutic control. The gastric inflammatory activity was evaluated from gastric histology and inflammation score, number of interleukin-10 (IL-10), interferon-gamma (INFgamma) and tumor necrosis factor-alpha (TNF-alpha) cytokine-producing cells in the gastric mucosa, and thickness of the mucus layer. Animals receiving treatment with the EPS-producing S. thermophilus CRL 1190 fermented milk showed a conserved gastric mucosa structure similar to that of healthy animals. Inflammation scores of the fermented milk-treated mice were lower than those of mice in the gastritis group (0.2 + or - 0.03 vs 2.0 + or - 0.6, P mucus gel layer (2.2 + or - 0.6 vs 1.0 + or - 0.3; 5.1 + or - 0.8 vs 1.5 + or - 0.4 in the corpus and antrum mucosa, respectively, P milk suspension of the purified EPS from S. thermophilus CRL1190 was also effective as therapy for gastritis. This study suggests that fermented milk with S. thermophilus CRL 1190 and/or its EPS could be used in novel functional foods as an alternative natural therapy for chronic gastritis induced by ASA.

    In The Netherlands, pharmaceutical-grade cultivated cannabis is distributed for medicinal purposes as commissioned by the Ministry of Health. Few studies have thus far described its therapeutic efficacy or subjective (adverse) effects in patients. The aims of this study are to assess the therapeutic satisfaction within a group of patients using prescribed pharmaceutical-grade cannabis and to compare the subjective effects among the available strains with special focus on their delta-9-tetrahydrocannabinol and cannabidiol content. In a cross-sectional and natural design, users of pharmaceutical-grade cannabis were investigated with questionnaires. Medical background of the patients was asked as well as experienced therapeutic effects and characteristics of cannabis use. Subjective effects were measured with psychometric scales and used to compare among the strains of cannabis used across this group of patients. One hundred two patients were included; their average age was 53 years and 76% used it for more than a year preceding this study. Chronic pain (53%; n = 54) was the most common medical indication for using cannabis followed by multiple sclerosis (23%; n = 23), and 86% (n = 88) of patients (almost) always experienced therapeutic satisfaction when using pharmaceutical cannabis. Dejection, anxiety, and appetite stimulation were found to differ among the 3 strains of cannabis. These results show that patients report therapeutic satisfaction with pharmaceutical cannabis, mainly pain alleviation. Some subjective effects were found to differ among the available strains of cannabis, which is discussed in relation to their different tetrahydrocannabinol/cannabidiol content. These results may aid in further research and critical appraisal for medicinally prescribed cannabis products.

  3. Therapeutic Effects of Extinction Learning as a Model of Exposure Therapy in Rats

    Current treatments for stress-related psychiatric disorders, such as depression and posttraumatic stress disorder (PTSD), are inadequate. Cognitive behavioral psychotherapies, including exposure therapy, are an alternative to pharmacotherapy, but the neurobiological mechanisms are unknown. Preclinical models demonstrating therapeutic effects of behavioral interventions are required to investigate such mechanisms. Exposure therapy bears similarity to extinction learning. Thus, we investigated the therapeutic effects of extinction learning as a behavioral intervention to model exposure therapy in rats, testing its effectiveness in reversing chronic stress-induced deficits in cognitive flexibility and coping behavior that resemble dimensions of depression and PTSD. Rats were fear-conditioned by pairing a tone with footshock, and then exposed to chronic unpredictable stress (CUS) that induces deficits in cognitive set-shifting and active coping behavior. They then received an extinction learning session as a therapeutic intervention by repeated exposure to the tone with no shock. Effects on cognitive flexibility and coping behavior were assessed 24 h later on the attentional set-shifting test or shock-probe defensive burying test, respectively. Extinction reversed the CUS-induced deficits in cognitive flexibility and coping behavior, and increased phosphorylation of ribosomal protein S6 in the medial prefrontal cortex (mPFC) of stress-compromised rats, suggesting a role for activity-dependent protein synthesis in the therapeutic effect. Inhibiting protein synthesis by microinjecting anisomycin into mPFC blocked the therapeutic effect of extinction on cognitive flexibility. These results demonstrate the utility of extinction as a model by which to study mechanisms underlying exposure therapy, and suggest these mechanisms involve protein synthesis in the mPFC, the further study of which may identify novel therapeutic targets.

    Ayahuasca is a psychedelic decoction originating from Amazonia. The ayahuasca-induced introspective experience has been shown to have potential benefits in the treatment of several pathologies, to protect mental health and to improve neuropsychological functions and creativity, and boost mindfulness. The underlying psychological processes related to the use of ayahuasca in a psychotherapeutic context are not yet well described in the scientific literature, but there is some evidence to suggest that psychological variables described in psychotherapies could be useful in explaining the therapeutic effects of the brew. In this study we explore the link between ayahuasca use and Decentering, Values and Self, comparing subjects without experience of ayahuasca (n = 41) with subjects with experience (n = 81). Results confirm that ayahuasca users scored higher than non-users in Decentering and Positive self, but not in Valued living, Life fulfillment, Self in social relations, Self in close relations and General self. Scores in Decentering were higher in the more experienced subjects (more than 15 occasions) than in those with less experience (less than 15 occasions). Our results show that psychological process variables may explain the outcomes in ayahuasca psychotherapy. The introduction of these variables is warranted in future ayahuasca therapeutic studies.

    In this study, the potential price for a therapeutic vaccine against Human Papilloma Virus (HPV)-16 & 18 (pre)-malignant cervical lesions is examined. A decision tree model was built in the context of the new Dutch cervical cancer-screening program and includes a primary test for the presence of HPV. Based on data of cervical cancer screening and HPV prevalence in the Netherlands, cohorts were created with HPV-16 or 18 positive women with cervical intraepithelial neoplasia (CIN) 2 or 3 or cervical cancer stage 1A (FIGO 1A). In the base case, the vaccine price was based on equal numbers of effective treatments in the vaccine branch and the current treatments branch of the model, and parity in cost, i.e. total cost in both branches are the same. The vaccine price is calculated by subtracting the cost of the vaccine branch from cost in the standard treatment branch and divided by the total number of women in the cohort, thereby equalizing costs in both strategies. Scenario analyses were performed taking quality adjusted life years (QALYs) into account with €20,000/QALY, €50,000/QALY and €80,000/QALY as corresponding thresholds. Sensitivity analyses were specifically targeted at the characteristics of the type-specific HPV test in the screening practice and vaccine efficacy. A probabilistic sensitivity analysis (PSA) was performed to quantify the level of uncertainty of the results found in the base case. In the base case, break-even vaccine prices of €381, €568 and €1697 were found for CIN 2, CIN 3 and FIGO 1A, respectively. The PSA showed vaccine pricing below €310, €490 and €1660 will be cost saving with a likelihood of 95% for CIN 2, CIN 3 and FIGO 1A, respectively. The vaccine price proved to be very sensitive for inclusion of QALY gains, including the HPV-type specific test into the Dutch screening practice and vaccine efficacy. Copyright © 2016 Elsevier Ltd.

    In the central nervous system, progranulin, a glycoprotein growth factor, plays a crucial role in maintaining physiological functions, and progranulin gene mutations cause TAR DNA-binding protein-43-positive frontotemporal lobar degeneration. Although several studies have reported that progranulin plays a protective role against ischaemic brain injury, little is known about temporal changes in the expression level, cellular localization, and glycosylation status of progranulin after acute focal cerebral ischaemia. In addition, the precise mechanisms by which progranulin exerts protective effects on ischaemic brain injury remains unknown. Furthermore, the therapeutic potential of progranulin against acute focal cerebral ischaemia, including combination treatment with tissue plasminogen activator, remains to be elucidated. In the present study, we aimed to determine temporal changes in the expression and localization of progranulin after ischaemia as well as the therapeutic effects of progranulin on ischaemic brain injury using in vitro and in vivo models. First, we demonstrated a dynamic change in progranulin expression in ischaemic Sprague-Dawley rats, including increased levels of progranulin expression in microglia within the ischaemic core, and increased levels of progranulin expression in viable neurons as well as induction of progranulin expression in endothelial cells within the ischaemic penumbra. We also demonstrated that the fully glycosylated mature secretory isoform of progranulin (∼88 kDa) decreased, whereas the glycosylated immature isoform of progranulin (58-68 kDa) markedly increased at 24 h and 72 h after reperfusion. In vitro experiments using primary cells from C57BL/6 mice revealed that the glycosylated immature isoform was secreted only from the microglia. Second, we demonstrated that progranulin could protect against acute focal cerebral ischaemia by a variety of mechanisms including attenuation of blood-brain barrier disruption

    The purpose of this study was to determine whether therapeutic touch in preterm infants can ameliorate their sensory punctate stimulus response in terms of brain activation measured by near-infrared spectroscopy. The study included 10 preterm infants at 34-40 weeks' corrected age. Oxyhaemoglobin (Oxy-Hb) concentration, heart rate (HR), arterial oxygen saturation (SaO2) and body movements were recorded during low-intensity sensory punctate stimulation for 1 s with and without therapeutic touch by a neonatal development specialist nurse. Each stimulation was followed by a resting phase of 30 s. All measurements were performed with the infants asleep in the prone position. sensory punctate stimulus exposure significantly increased the oxy-Hb concentration but did not affect HR, SaO2 and body movements. The infants receiving therapeutic touch had significantly decreased oxy-Hb concentrations over time. Therapeutic touch in preterm infants can ameliorate their sensory punctate stimulus response in terms of brain activation, indicated by increased cerebral oxygenation. Therefore, therapeutic touch may have a protective effect on the autoregulation of cerebral blood flow during sensory punctate stimulus in neonates.

    A brief outline of stem cells, stem cell therapy and therapeutic cloning is given. The position of therapeutic cloning with regard to other embryonic manipulations - IVF-based reproduction, embryonic stem formation from IVF embryos and reproductive cloning - is indicated. The main ethically challenging stages in therapeutic cloning are considered to be the nuclear transfer process including the source of eggs for this and the destruction of an embryo to provide stem cells for therapeutic use. The extremely polarised nature of the debate regarding the status of an early human embryo is noted, and some potential alternative strategies for preparing immunocompatible pluripotent stem cells are indicated

    Therapeutic communities posit favorable treatment outcomes by relying on the community as the healing agent (Deleon 2000). Active treatment participation and treatment tenure are two domains that are positive predictors of positive treatment outcomes over time. Some of the more important domains that remain to be thoroughly investigated in international research on therapeutic community (TC) treatment outcome studies are the underlying effects of culture on the treatment process. Cultural components play a significant role, as also reported by various TC participants over the years (such as the effects of health literacy on sustaining abstinence from drug use over the long term, Tiburcio 2008). In recent years, health literacy has taken on a significant role in order for individuals to readily understand their needs (Schillinger et al 2002; Jorm et al 1997); or as pertains to feeling shamed in the process (Parikh et al 1996). As these and other studies suggest, the cultural competence of the providers is equally important. To our knowledge the " International TC Study " and findings presented herein constitute one of only a few studies that have conducted investigations comparing therapeutic community treatment modifications internationally, from the perspective of the participants themselves and which consider cultural components of this process. One key advantage of the resulting Qualitative datasets and analyses is that it not only includes residents' perspectives, and staff experiential elements, but importantly, incorporates staff debriefings about their respective interactions at each of the international treatment modalities, presenting well rounded depictions of each of these milieus. To that end, the data examined here presents an enhanced portrait of the provider-patient treatment dynamic, and lends voice to the various aspects of treatment participation in light of these cultural issues, and from the perspective of providers, as well as the participants.

    The National Academies of Sciences, Engineering and Medicine conducted a rapid turn-around comprehensive review of recent medical literature on The Health Effects of Cannabis and Cannabinoids. The 16-member committee adopted the key features of a systematic review process, conducting an extensive search of relevant databases and considered 10,000 recent abstracts to determine their relevance. Primacy was given to recently published systematic reviews and primary research that studied one of the committee's 11 prioritized health endpoints- therapeutic effects; cancer incidence; cardiometabolic risk; respiratory disease; immune function; injury and death; prenatal, perinatal and postnatal outcomes; psychosocial outcomes; mental health; problem Cannabis use; and Cannabis use and abuse of other substances. The committee developed standard language to categorize the weight of evidence regarding whether Cannabis or cannabinoids use for therapeutic purposes are an effective or ineffective treatment for the prioritized health endpoints of interest. In the Therapeutics chapter reviewed here, the report concluded that there was conclusive or substantial evidence that Cannabis or cannabinoids are effective for the treatment of pain in adults; chemotherapy-induced nausea and vomiting and spasticity associated with multiple sclerosis. Moderate evidence was found for secondary sleep disturbances. The evidence supporting improvement in appetite, Tourette syndrome, anxiety, posttraumatic stress disorder, cancer, irritable bowel syndrome, epilepsy and a variety of neurodegenerative disorders was described as limited, insufficient or absent. A chapter of the NASEM report enumerated multiple barriers to conducting research on Cannabis in the US that may explain the paucity of positive therapeutic benefits in the published literature to date.

    Present studies were aimed to research the possible application of a radiosensitizer, nicotinamide, to increase the therapeutical effect of radioiodine. There were used goitrous and normal rats with growing dose of Iodine 131, with and without simultaneous treatment with nicotinamide. The obtained results show that the nicotinamide treatment importantly increases the thyroid radio destructive effect induced by radioiodine. Under these experimental conditions, nicotinamide induces to a significant increase of thyroid vascularisation, without changes in the proteins ADP-ribosylation activity. These results show, for the first time, the radiosensitizer effect of nicotinamide in front of Iodine 131 and give the possibility of using it in the treatment of hyperthyroid or thyroid difference cancer patients.

    Ionizing radiation is known to stimulate the generation of oxygen radicals which destabilize organic molecules resulting in a decrease of the system's antioxidant potential. Propolis (bee glue) is a complex mixture of natural substances that exhibits a broad spectrum of biological activities. As the possibility exists that it may exert a radio protections role, the present study aimed to examine the preventive and therapeutic effects of propolis on the gamma irradiation-induced changes in antioxidant status and certain biochemical parameters. HPLC chromatography for analysis of propolis showed that the number of identified phenols was 6 compounds (natural antioxidants). Male albino rats were exposed to 6 Gy of gamma radiation. The efficiency of propolis was evaluated when propolis was administered orally to rats at a dose of 200 mg/kg as follow: non-irradiated rats received orally propolis extract for 6 weeks (positive control) and rats received orally propolis extract for 3 weeks before or after gamma irradiation. The obtained results revealed that propolis given to rats before gamma irradiation protect the hazardous effects of gamma irradiation. In addition, administration of propolis to gamma irradiated rats caused significant enhancement in hepatic antioxidant enzymes (glutathion reductase; GR and catalase; CAT) and total antioxidant capacity associated with a remarkable decrease in the level of lipid peroxidation (TBARS). Also, it significantly reduced the changes induced by gamma irradiation in the serum levels of glucose and liver enzymes; aminotransferases (AST, ALT) and alkaline phosphatase (ALP). In addition, a significant improvement was observed in the serum levels of total cholesterol (TC), triglycerides (TG), low density lipoprotein- cholesterol (LDL-C) and high density lipoprotein-cholesterol (HDL-C). In conclusion, the positive results obtained in the gamma irradiated rats given propolis indicated that propolis could be considered as effective

    Therapeutic patient education is effective for various patient outcomes; however, healthcare professionals sometimes lack the motivation to carry out patient education. Surprisingly, this issue has rarely been addressed in research. Therefore, this study explores healthcare professionals' perceived barriers to and motivation for therapeutic patient education. Healthcare professionals, mainly nurses, working in different French hospitals were interviewed. Thematic content analysis was performed. Findings included a lack of skills, knowledge, and disillusionment of the effectiveness of therapeutic patient education were features of a demotivated attitude. In contrast, a positive attitude was observed when therapeutic patient education met a need to work differently and more effectively. A key factor motivating professionals was the integration of therapeutic patient education in routine care within a multidisciplinary team. To keep healthcare professionals motivated, managers should ensure that therapeutic patient education is implemented in accordance with its core principles: a patient-centered approach within a trained multidisciplinary team. In the latter case, therapeutic patient education is viewed as an efficient and rewarding way to work with patients, which significantly motivates healthcare professionals. © 2017 John Wiley & Sons Australia, Ltd.

    Full Text Available Acupuncture is regarded as an effective therapy for cerebral ischemia. Different acupuncture manipulations and durations may result in different therapeutic effects. In the present study, the Neiguan (PC6 acupoint of rats with occluded middle cerebral arteries was needled at a fixed frequency (3 Hz with different durations, i.e., 5, 60 and 180 seconds under a twisting-rotating acupuncture method. Results showed that different durations of acupuncture had different therapeutic effects, with 60 seconds yielding a better therapeutic effect than the other two groups. This duration of treatment demonstrated rapid cerebral blood flow, encouraging recovery of neurological function, and small cerebral infarct volume. Experimental findings indicated that under 3 Hz frequency, the treatment of needling Neiguan for 60 seconds is effective for ischemic stroke

    Full Text Available Background: The most common types of non-malignant prostate diseases are benign prostatic hyperplasia (BPH and chronic prostatitis (CP. The aim of this study was to find out whether thermobalancing therapy with a physiotherapeutic device is effective for BPH and CP. Methods: During a 2.5-year period, 124 men with BPH over the age of 55 were investigated. Clinical parameters were tested twice: via the International Prostate Symptom Score (IPSS and via ultrasound measurement of prostate volume (PV and uroflowmetry maximum flow rate (Qmax, before and after six months of therapy. In 45 men with CP under the age of 55, the dynamics of the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI were studied. Results: The results of the investigated index tests in men with BPH confirmed a decrease in IPSS (p < 0.001, a reduction in PV (p < 0.001, an increase in Qmax (p < 0.001, and an improvement of quality of life (QoL (p < 0.001. NIH-CPSI scores in men with CP indicated positive dynamics. Conclusions: The observed positive changes in IPSS, PV, and Qmax in men with BPH and the improvement in NIH-CPSI-QoL in patients with CP after using a physiotherapeutic device for six months as mono-therapy, support the view that thermobalancing therapy with the device can be recommended for these patients. Furthermore, the therapeutic device is free of side effects.

    Throughout history, many different cultures have recognized the potential use of garlic for prevention and treatment of different diseases. Recent studies support the effects of garlic and its extracts in a wide range of applications. These studies raised the possibility of revival of garlic therapeutic values in different diseases. Different compounds in garlic are thought to reduce the risk for cardiovascular diseases, have anti-tumor and anti-microbial effects, and show benefit on high blood glucose concentration. However, the exact mechanism of all ingredients and their long-term effects are not fully understood. Further studies are needed to elucidate the pathophysiological mechanisms of action of garlic as well as its efficacy and safety in treatment of various diseases. PMID:25050296

    The comparison was made of the protective (the administration 3 h before irradiation with a dose of 7.3 Gy) and therapeutic (the administration immediately and later after exposure) effects of soya oil (150 mg/kg) and oil solution of ubiquinone-9 (100-200 mg/kg) on survival of exposed rats. It was shown that soya oil and ubiquinone-9 increased the survival rate of rats when administered before and, to a lesser extent, immediately after irradiation. Corn oil administered immediately after exposure increased the survival rate as well. DMF for the therapeutic effect of soya oil solution of ubiquinone-9 was 1.08

    A randomized controlled study investigated the effects of therapeutic climbing in patients with chronic low back pain. Before and after 4 weeks of training, physical and mental well-being were measured by two questionnaires (36-Item Short Form Health Survey [SF-36]; Hannover Functional Ability Questionnaire for measuring back pain-related disability [FFbH-R]). Therapeutic climbing has been suggested to increase muscular strength and perceived physical and mental well-being. This study focused on the psychological effects of therapeutic climbing and compared it with standard exercise therapy. Therapeutic climbing has become increasingly popular in rehabilitation and its effects on muscular strengthening have been shown. Therapeutic climbing has also been suggested to yield psychological effects such as changes in attentional focus from pain to physical capabilities. To date, no controlled clinical trial has investigated these psychological effects and it is unclear whether therapeutic climbing is comparable or superior to other forms of exercise. Twenty-eight patients with chronic low back pain conducted either a therapeutic climbing or a standard exercise regime. Each program took 4 weeks, including four guided training sessions per week. Before and after the program, patients answered two questionnaires assessing their physical and mental well-being. For the Hannover Functional Ability Questionnaire for measuring back pain-related disability, there was no difference before versus after or between the treatments. For the SF-36, both treatments showed significant improvements in 3/8 subscales of the SF-36. In 2/8 subscales, only the participants of the therapeutic climbing improved and in 1/8 subscales the converse was true. Comparing both groups, significantly larger improvements were found after therapeutic climbing in two subscales of the SF-36: physical functioning and general health perception. The benefits of therapeutic climbing were comparable with those of

    Clinical experience has obviously shown a positive effect of application of sulfated amino acids on degenerative cartilage diseases. L-Cystin, presumed to be of therapeutic effect, was autoradiographically localized in articular, columnar and intervertebral cartilage as well as in skeletal musculature. In 10 days old NMRI-mice, we had shown a dose-dependent incorporation of the radioactively labelled /sup 35/S-Cystin in hair follicle. These statistically significant differences had been measured by quantitative autoradiographical microscope photometry. The sulfated amino acids are also proven in nail matrix, nail hyponychium as well as in cartilage and skeletal musculature. Besides a localization of radioactively labelled L-Cystin in tissues, presumed as target organs of a therapeutic effect, there is still lacking an experimental proof of efficacy on cell proliferation and functional metabolism e.g. in arthrosis by suitable animal models.

    It has been six decades since synthesis of organophosphates, but this chapter has not yet come to a closure. Toxic effects of organophosphates are well known and the current therapeutic scheme includes supportive therapy and antidotes. There is a dilemma on whether and when to apply gastric lavage and activated charcoal. According to Position Statement (by EAPCCT) it should be applied only if the patient presents within one hour of ingestion, with potentially lethal ingested dose. Atropine, a competitive antagonist of acetylcholine at m-receptors, which antagonizes bronchosecretion and bronchoconstriction, is the corner stone of acute organophosphate poisoning therapy. There were many attempts to find a more efficient drug, including glycopyrrolate which has been used even in clinical trials, but it still can not replace atropine. The only dilemma about atropine usage which still exists, concerns usage of high atropine dose and scheme of application. The most efficient atropinization is achieved with bolus doses of 1-2mg of atropine i.v push, with repeating the dose on each 5 minutes until signs of atropinization are registered. Diazepam, with its GABA stabilizing effect, reduces central nervous system damage and central respiratory weakness. Oximes reactivate phosphorylated acetylcholinesterase, which still has not gone ageing, reducing acetylcholine concentration and cholinergic crisis. These effects are clearly demonstrated in experimental conditions, but the clinical significance of oximes is still unclear and there are still those who question oxime therapy. For those who approve it, oxime dosage, duration of therapy, the choice of oxime for certain OP is still an open issue. We need new, more efficient antidotes, and those that are in use are only the small part of the therapy which could be used. Experimental studies show favorable therapeutic effect of many agents, but none of them has been introduced in standard treatment of OPI poisoning in the last 30

    Activation of innate immunity has direct effects in modulating viral replication, tumor growth, angiogenesis, and inflammatory and other immunological processes. It is now established that unmodified siRNA can activate this innate immune response and therefore there is real potential for siRNA to elicit nonspecific therapeutic effects in a wide range of disease models. Here we demonstrate that in a murine model of influenza infection, the antiviral activity of siRNA is due primarily to immune stimulation elicited by the active siRNA duplexes and is not the result of therapeutic RNA interference (RNAi) as previously reported. We show that the misinterpretation stems from the use of a particular control green fluorescent protein (GFP) siRNA that we identify as having unusually low immunostimulatory activity compared with the active anti-influenza siRNA. Curiously, this GFP siRNA has served as a negative control for a surprising number of groups reporting therapeutic effects of siRNA. The inert immunologic profile of the GFP sequence was unique among a broad panel of published siRNAs, all of which could elicit significant interferon induction from primary immune cells. This panel included eight active siRNAs against viral, angiogenic, and oncologic targets, the reported therapeutic efficacy of which was based on comparison with the nonimmunostimulatory GFP siRNA. These results emphasize the need for researchers to anticipate, monitor, and adequately control for siRNA-mediated immune stimulation and calls into question the interpretation of numerous published reports of therapeutic RNAi in vivo. The use of chemically modified siRNA with minimal immunostimulatory capacity will help to delineate more accurately the mechanism of action underlying such studies.

    The present study examined variables related to the quality of the therapeutic alliance in out-patients with schizophrenia. We expected recovery orientation and insight to be positively, and self-stigma to be negatively associated with a good therapeutic alliance. We expected these associations to be independent from age, clinical symptoms (i.e. positive and negative symptoms, depression), and more general aspects of relationship building like avoidant attachment style and the duration of treatment by the current therapist. The study included 156 participants with DSM-IV diagnoses of schizophrenia or schizoaffective disorder in the maintenance phase of treatment. Therapeutic alliance, recovery orientation, self-stigma, insight, adult attachment style, and depression were assessed by self-report. Symptoms were rated by interviewers. Hierarchical multiple regressions revealed that more recovery orientation, less self-stigma, and more insight independently were associated with a better quality of the therapeutic alliance. Clinical symptoms, adult attachment style, age, and the duration of treatment by current therapist were unrelated to the quality of the therapeutic alliance. Low recovery orientation and increased self-stigma might undermine the therapeutic alliance in schizophrenia beyond the detrimental effect of poor insight. Therefore in clinical settings, besides enhancing insight, recovery orientation, and self-stigma should be addressed. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    The recent progress in human therapeutics has been made possible thanks to molecular biology and its use in producing proteins having the same sequence and structure as that of human proteins. The use of GMOs allows production of proteins with high added value in therapeutics, which are of satisfactory quality. GMOs may also be directly administered to patients as gene therapy vectors. However, the use of GMOs in therapeutics must take into consideration some risks, particularly those of microbiological contamination, of neo-antigenicity as well as environmental risks with regard to the way of use of the GMO. Nevertheless, those risks are taken in due consideration in the development of these new medicinal products; solutions have been found to allow their use in therapeutics with a very positive benefit/risk ratio. Medicinal products from biotechnology have enabled considerable therapeutic progress without compromising health security.

    Critical limb ischemia is a severe form of peripheral artery disease (PAD) for which neither surgical revascularization nor endovascular therapy nor current medicinal therapy has sufficient therapeutic effects. Peroxisome proliferator activated receptor-γ agonists present angiogenic activity in vitro; however, systemic administration of peroxisome proliferator-activated receptor-γ agonists is hampered by its side effects, including heart failure. Here, we demonstrate that the nanoparticle (NP)-mediated delivery of the peroxisome proliferator activated receptor-γ agonist pioglitazone enhances its therapeutic efficacy on ischemia-induced neovascularization in a murine model. In a nondiabetic murine model of hindlimb ischemia, a single intramuscular injection of pioglitazone-incorporated NP (1 µg/kg) into ischemic muscles significantly improved the blood flow recovery in the ischemic limbs, significantly increasing the number of CD31-positive capillaries and α-smooth muscle actin-positive arterioles. The therapeutic effects of pioglitazone-incorporated NP were diminished by the peroxisome proliferator activated receptor-γ antagonist GW9662 and were not observed in endothelial NO synthase-deficient mice. Pioglitazone-incorporated NP induced endothelial NO synthase phosphorylation, as demonstrated by Western blot analysis, as well as expression of multiple angiogenic growth factors in vivo, including vascular endothelial growth factor-A, vascular endothelial growth factor-B, and fibroblast growth factor-1, as demonstrated by real-time polymerase chain reaction. Intramuscular injection of pioglitazone (1 µg/kg) was ineffective, and oral administration necessitated a >500 μg/kg per day dose to produce therapeutic effects equivalent to those of pioglitazone-incorporated NP. NP-mediated drug delivery is a novel modality that may enhance the effectiveness of therapeutic neovascularization, surpassing the effectiveness of current treatments for peripheral artery

    The sacroiliac joint is well known as a cause of low back and lower extremity pain. Prevalence estimates are 10% to 25% in patients with persistent axial low back pain without disc herniation, discogenic pain, or radiculitis based on multiple diagnostic studies and systematic reviews. However, at present there are no definitive management options for treating sacroiliac joint pain. To evaluate the diagnostic accuracy and therapeutic effectiveness of sacroiliac joint interventions. A systematic review of the diagnostic accuracy and therapeutic effectiveness of sacroiliac joint interventions. The available literature on diagnostic and therapeutic sacroiliac joint interventions was reviewed. The quality assessment criteria utilized were the Quality Appraisal of Reliability Studies (QAREL) checklist for diagnostic accuracy studies, Cochrane review criteria to assess sources of risk of bias, and Interventional Pain Management Techniques-Quality Appraisal of Reliability and Risk of Bias Assessment (IPM-QRB) criteria for randomized therapeutic trials and Interventional Pain Management Techniques-Quality Appraisal of Reliability and Risk of Bias Assessment for Nonrandomized Studies (IPM-QRBNR) for observational therapeutic assessments. The level of evidence was based on a best evidence synthesis with modified grading of qualitative evidence from Level I to Level V. Data sources included relevant literature published from 1966 through March 2015 that were identified through searches of PubMed and EMBASE, manual searches of the bibliographies of known primary and review articles, and all other sources. For the diagnostic accuracy assessment, and for the therapeutic modalities, the primary outcome measure of pain relief and improvement in functional status were utilized. A total of 11 diagnostic accuracy studies and 14 therapeutic studies were included. The evidence for diagnostic accuracy is Level II for dual diagnostic blocks with at least 70% pain relief as the criterion

  11. Therapeutic use of the rebound effect of modern drugs: "New homeopathic medicines"

    Directory of Open Access Journals (Sweden)

    Marcus Zulian Teixeira

    Full Text Available Summary The homeopathic treatment is based on the principle of therapeutic similitude, employing medicines that cause certain disorders to treat similar manifestations, stimulating a reaction of the organism against its own ailments. The occurrence of this secondary reaction of the organism, opposite in nature to the primary action of the medicines, is evidenced in the study of the rebound (paradoxical effect of several classes of modern drugs. In this work, in addition to substantiate the principle of similitude before the experimental and clinical pharmacology, we suggest a proposal to employ hundreds of conventional drugs according to homeopathic method, applying the therapeutic similitude between the adverse events of medicines and the clinical manifestations of patients. Describing existing lines of research and a specific method for the therapeutic use of the rebound effect of modern drugs (http://www.newhomeopathicmedicines.com, we hope to minimize prejudices related to the homeopathy and contribute to a broadening of the healing art.

    2018-03-01

    Full Text Available Recent reports on the effects of psychedelic-assisted therapies for mood disorders and addiction, as well as the effects of psychedelics in the treatment of cluster headache, have demonstrated promising therapeutic results. In addition, the beneficial effects appear to persist well after limited exposure to the drugs, making them particularly appealing as treatments for chronic neuropsychiatric and headache disorders. Understanding the basis of the long-lasting effects, however, will be critical for the continued use and development of this drug class. Several mechanisms, including biological and psychological ones, have been suggested to explain the long-lasting effects of psychedelics. Actions on the neuroendocrine system are some such mechanisms that warrant further investigation in the study of persisting psychedelic effects. In this report, we review certain structural and functional neuroendocrinological pathologies associated with neuropsychiatric disorders and cluster headache. We then review the effects that psychedelic drugs have on those systems and provide preliminary support for potential long-term effects. The circadian biology of cluster headache is of particular relevance in this area. We also discuss methodologic considerations for future investigations of neuroendocrine system involvement in the therapeutic benefits of psychedelic drugs.

    Proofs of the therapeutic efficiency of balneological radon applications administered to patients suffering from rheumatic diseases, investigations into the biological action mechanism associated with the alpha particles emitted by radon and its radioactive daughter products, and the comparative risk assessment of radon treatment and medicinal pain therapy have been the research projects whose results are summarized in this book. Controlled clinical studies, if possible performed as prospective, randomized and placebo-controlled double blind studies, have given evidence that the therapeutic effects of balneological radon applications - long-lasting pain reduction and reduced consumption of medicines compared with controls - are significantly persisting over many post-treatment months. The molecular and cellular mechanism of action underlying these long-lasting therapeutic effects has been identified as the down-regulation of cellular immune responses, initiated by cellular apoptosis sequential to low alpha particle doses and by the subsequent release of anti-inflammatory cytokines. The unwanted side-effects of non-steroidal anti-rheumatic drug treatments have to be compared with the absence of side effects from the balneological radon applications which merely involve radiation doses well below the mean value and the fluctuation width of the annual doses attributable to everybody's natural radiation exposure.

    2016-01-01

    Ayahuasca is an Amazonian psychoactive brew of two main components. Its active agents are β-carboline and tryptamine derivatives. As a sacrament, ayahuasca is still a central element of many healing ceremonies in the Amazon Basin and its ritual consumption has become common among the mestizo populations of South America. Ayahuasca use amongst the indigenous people of the Amazon is a form of traditional medicine and cultural psychiatry. During the last two decades, the substance has become increasingly known among both scientists and laymen, and currently its use is spreading all over in the Western world. In the present paper we describe the chief characteristics of ayahuasca, discuss important questions raised about its use, and provide an overview of the scientific research supporting its potential therapeutic benefits. A growing number of studies indicate that the psychotherapeutic potential of ayahuasca is based mostly on the strong serotonergic effects, whereas the sigma-1 receptor (Sig-1R) agonist effect of its active ingredient dimethyltryptamine raises the possibility that the ethnomedical observations on the diversity of treated conditions can be scientifically verified. Moreover, in the right therapeutic or ritual setting with proper preparation and mindset of the user, followed by subsequent integration of the experience, ayahuasca has proven effective in the treatment of substance dependence. This article has two important take-home messages: (1) the therapeutic effects of ayahuasca are best understood from a bio-psycho-socio-spiritual model, and (2) on the biological level ayahuasca may act against chronic low grade inflammation and oxidative stress via the Sig-1R which can explain its widespread therapeutic indications.

    The Second Symposium on the Biological effects of 224 Ra, held at Neuherberg, was focused on two topical aspects of radiation protection. One aspect was the long-term effects of high-LET ionizing radiations on man and the quantitative data involved in risk assessment at low doses. The evaluation of epidemiological studies and experimental research was discussed in order to provide facts and figures contributing to an objective assessment of the radiation hazard from incorporated radionuclides. The other aspect was that of radiation protection in medicine. In the case of 224 Ra treatment of ankylosing spondylitis the questions of benefit and risk of this therapeutic use of ionizing radiations were discussed, the aim being to achieve the therapeutic effect while reducing radiation exposure - and therefore the hazard - to a minimum. The proceedings contain the complete texts of 23 papers as well as the final round table discussions

    Full Text Available Cryptosporidiosis affects humans of all ages, particularly malnourished children and those with compromised immune systems such as HIV/AIDS. This study investigated the therapeutic effects of acetylspiramycin and garlicin on Cryptosporidium infection in institutionalized male drug users receiving rehabilitative treatment. Examination of stool specimens from 903 drug users via modified acid-fast bacilli staining resulted in 172 positive cases. Among them 151 subjects consented to participate in a randomized trial of acetylspiramycin and garlicin in four groups: acetylspiramycin plus garlicin, acetylspiramycin only, garlicin only, and placebo control. The cryptosporidiosis rate was higher in younger subjects with longer drug use history than subjects who are older with shorter history of drug use. After two segments of treatments, 76.2% of the cases achieved negative test results, with the four groups achieving the rates of 92.1%, 76.7%, 72.2%, and 61.8%, respectively (χ2 = 9.517, P = 0.023. These results indicate clinical potential of garlicin in conjunction with acetylspiramycin in treating cryptosporidiosis.

    Tumor irradiation of the head-neck area is accompanied by the development of a so-called radiation caries in the treated patients. In spite of conservative therapeutic measures, the process results in tooth destruction. The present study investigated the effects of irradiation on the demineralization and remineralization of the dental tissue. For this purpose, retained third molars were prepared and assigned either to a test group, which was exposed to fractional irradiation up to 60 Gy, or to a non-irradiated control group. Irradiated and non-irradiated teeth were then demineralized using acidic hydroxyl-cellulose gel; afterwards the teeth were remineralized using either Bifluorid12 registered or elmex gelee registered . The nanoindentation technique was used to measure the mechanical properties, hardness and elasticity, of the teeth in each of the conditions. The values were compared to the non-irradiated control group. Irradiation decreased dramatically the mechanical parameters of enamel and dentine. In non-irradiated teeth, demineralization had nearly the same effects of irradiation on the mechanical properties. In irradiated teeth, the effects of demineralization were negligible in comparison to non-irradiated teeth. Remineralization with Bifluorid12 registered or elmex gelee registered led to a partial improvement of the mechanical properties of the teeth. The enamel was more positively affected, by remineralization than the dentine. (orig.)

    Full Text Available Saffron, the dried red-orange stigmas of Crocus sativus L, has been known as a flavoring agent, food coloring and traditional herbal medicine. Pharmacological effects of saffron are mainly attributed to crocin, crocetin, picrocrocin and safranal. These components especially crocin, have significant effects including antidepressant and anticonvulsant, analgesic, anti-cancer and other therapeutic effects on different parts of our body namely cardiovascular, immune, respiratory, genital-urinary and central nervous system. According to the reports and findings, saffron plays a key role to cure different digestive system disorders via chemopreventive, inhibition of cell proliferation, induction of apoptosis, antioxidant effects and radical scavenging, genoprotective property, prevention of lipid peroxidation and anti-inflammatory processes. The outcome of the above mentioned mechanisms shows potential therapeutic properties of saffron against liver cancer, hepatotoxicity, fatty liver, hyperlipidemia, stomach cancer, peptic ulcer, colon cancer, ulcerative colitis, diabetes and pancreas cancer and ileum contractions. According to global statistics, the susceptibility to intestinal diseases is considered as a significant matter and can be important in health planning in any community. Several strategies for treatment and prevention of the digestive system diseases have provided that the use of herbal remedies seems effective and useful. Considering the available findings, the present study aims to introduce saffron as a prophylactic and therapeutic agent against gastrointestinal tract disorders. However, further clinical studies seem necessary in various aspects of saffron effects in different parts of body to verify these findings.

    Translational nanomedicine occurs only through the successful integration of multiple inputs and iterative modifications. The therapeutic window plays a pivotal role in the trajectory of translational nanomedicine. Often defined in terms of the range of dosage for safe and effective therapeutic effect, a second definition of the therapeutic window refers to the often narrow temporal window in which a therapeutic effect can be obtained. Expanding the second definition to explicitly include the spatial dimension, this article explores aspects of the therapeutic spaces created by nanomedicine that shift the traditional dimensions of symptom, sign and pathology. This article analyzes three aspects of the therapeutic window in nanomedicine - temporal, spatial and manner of construction and their impact on the dimensions of modern medicine.

    Full Text Available The objective of this study is to assess the findings of selected articles regarding the therapeutic effects of yoga and to provide a comprehensive review of the benefits of regular yoga practice. As participation rates in mind-body fitness programs such as yoga continue to increase, it is important for health care professionals to be informed about the nature of yoga and the evidence of its many therapeutic effects. Thus, this manuscript provides information regarding the therapeutic effects of yoga as it has been studied in various populations concerning a multitude of different ailments and conditions. Therapeutic yoga is defined as the application of yoga postures and practice to the treatment of health conditions and involves instruction in yogic practices and teachings to prevent reduce or alleviate structural, physiological, emotional and spiritual pain, suffering or limitations. Results from this study show that yogic practices enhance muscular strength and body flexibility, promote and improve respiratory and cardiovascular function, promote recovery from and treatment of addiction, reduce stress, anxiety, depression, and chronic pain, improve sleep patterns, and enhance overall well-being and quality of life.

    Full Text Available Over the last decades, Positive Psychology (PP has promoted the scientific study of positive life changes in the aftermath of cancer. These have been integrated within negative life changes, based on the same human experience framework. Innovative interventions have been designed, prioritizing the pathways to the reduction of emotional distress and psychopathology in cancer, through the facilitation of positive psychological functioning. These interventions have achieved promising results. A theoretical and integrative review of the PP-related constructs was performed in the relevant databases (PsycINFO, PubMed, Web of Science, Scopus, etc.. These constructs have been linked to positive life changes after cancer and their therapeutic potential. Finally, we provide a summary of a positive psychotherapy program for cancer survivors, indicating the therapeutic strategies that facilitate positive life changes in the aftermath of cancer. Positive life changes after suffering cancer are more the norm than the exception. These changes play an important role in psychosocial adjustment, adherence to cancer treatments, well-being and quality of life. Psychological treatment programs based on PP achieve promising results with cancer. These programs are capable of complementing and improving the outcomes achieved by traditional stress-management programs.

    The cumulative effect of repeated traumatic experiences in early childhood incrementally increases the risk of adjustment problems later in life. Surviving traumatic environments can lead to the development of an interrelated constellation of emotional and interpersonal symptoms termed complex posttraumatic stress disorder (CPTSD). Effective treatment of trauma begins with a multimethod psychological assessment and requires the use of several evidence-based therapeutic processes, including establishing a safe therapeutic environment, reprocessing the trauma, constructing a new narrative, and managing emotional dysregulation. Therapeutic Assessment (TA) is a semistructured, brief intervention that uses psychological testing to promote positive change. The case study of Kelly, a middle-aged woman with a history of repeated interpersonal trauma, illustrates delivery of the TA model for CPTSD. Results of this single-case time-series experiment indicate statistically significant symptom improvement as a result of participating in TA. We discuss the implications of these findings for assessing and treating trauma-related concerns, such as CPTSD.

    To determine the long-range psychological effects of therapeutic abortion, 50 women (aged from 13-44 years), who were granted abortions between 1967 and 1968 Because of possible impairment of mental and/or physical health, were analyzed by use of demographic questionnaires, psychological tests, and interviews. Testing revealed that 44 women had psychiatric problems at time of abortion. 43 patients were followed for 3-6 months. The follow-up interviews revealed that 29 patients reacted positively after abortion, 10 reported no significant change and 4 reacted negatively. 37 would definitely repeat the abortion. Women under 21 years of age felt substantially more ambivalent and guilty than older patients. A study of 36 paired pre- and post-abortion profiles showed that 15 initially abnormal tests had become normal. There was a significant increase in contraceptive use among the patients after the abortion, but 4 again became pregnant and 8 were apparently without consistent contraception. It is concluded that the abortions were therapeutic, but physicians are encouraged to be aware of psychological problems in abortion cases. Strong psychological and contraceptive counselling should be exercised.

  8. Therapeutic Potential of Non-Psychotropic Cannabidiol in Ischemic Stroke

    Directory of Open Access Journals (Sweden)

    Michihiro Fujiwara

    2010-07-01

    Full Text Available Cannabis contains the psychoactive component delta9-tetrahydrocannabinol (delta9-THC, and the non-psychoactive components cannabidiol (CBD, cannabinol, and cannabigerol. It is well-known that delta9-THC and other cannabinoid CB1 receptor agonists are neuroprotective during global and focal ischemic injury. Additionally, delta9-THC also mediates psychological effects through the activation of the CB1 receptor in the central nervous system. In addition to the CB1 receptor agonists, cannabis also contains therapeutically active components which are CB1 receptor independent. Of the CB1 receptor-independent cannabis, the most important is CBD. In the past five years, an increasing number of publications have focused on the discovery of the anti-inflammatory, anti-oxidant, and neuroprotective effects of CBD. In particular, CBD exerts positive pharmacological effects in ischemic stroke and other chronic diseases, including Parkinson’s disease, Alzheimer’s disease, and rheumatoid arthritis. The cerebroprotective action of CBD is CB1 receptor-independent, long-lasting, and has potent anti-oxidant activity. Importantly, CBD use does not lead to tolerance. In this review, we will discuss the therapeutic possibility of CBD as a cerebroprotective agent, highlighting recent pharmacological advances, novel mechanisms, and therapeutic time window of CBD in ischemic stroke.

    Full Text Available Abstract Background: Learning disorders is one of the most common problems of students, which attracted the attention of many psychologists and many studies have been conducted on the effectiveness of various interventions on different classes of learning disorder. The present study aimed to conclude general conclusions about the effectiveness of various educational and therapeutic interventions and the discovery of possible moderating variables. Materials and Methods: In order to achieve the research purpose by using meta-analysis method, quantitative results of 128 selected researches which were obtained according to the criteria for entering and leaving and using keywords were used. In total, 623 primary effect sizes were obtained and analyzed by using CMA2 software. Results: The results of the analysis showed that amount of combined effect size of the educational and therapeutic interventions on learning disorders was 1.13, and after dividing into multiple predecessor and consequence variables, the amounts of the combined effect size for educational interventions and therapeutic interventions for overall class of learning disabilities were respectively 0.74 and 1.26, for reading disorder 0.87 and 1.01, for writing disorder 1.20 and 1.22, and for mathematical disorder 1.29 and 1.26 that all of these effects size were significant (p≤0.001. Also, the results of independent t-test showed that the difference in the effectiveness of therapeutic interventions on reading disorder and educational interventions on mathematical disorder is significant (p≤0.001. Conclusion: Based on the size of the effects obtained, it can be said that educational and therapeutic interventions have a very high effect on learning disabilities, and the use of therapeutic interventions for reading disorder and educational interventions for mathematical disorder is more effective.

    This review aims to emphasize how therapeutic inertia, the failure of clinicians to intensify treatment when blood pressure rises or remains above therapeutic goals, contributes to suboptimal blood pressure control in hypertensive populations. Studies reveal that the therapeutic inertia is quite common and contributes to suboptimal blood pressure control. Quality improvement programs and standardized approaches to support antihypertensive treatment intensification are ways to combat therapeutic inertia. Furthermore, programs that utilize non-physician medical professionals such as pharmacists and nurses demonstrate promise in mitigating the effects of this important problem. Therapeutic inertia impedes antihypertensive management and requires a broad effort to reduce its effects. There is an ongoing need for renewed focus and research in this area to improve hypertension control.

    To observe the therapeutic effect of hydrotherapy with Chinese drugs (HT-C) in early intervention on children hypoxic ischemic encephalopathy (HIE). HIE children were assigned to the treatment group and the control group, 50 in each, at random depending on the willingness of patients' parents. Both groups received the conventional functional training, according to the "0 -3-year-old early intervention outline", but for the treatment group, HT-C was applied additionally. Indexes for quality of sleep, gross motor function, severity of spasm and intellectual development were observed and compared before and after treatment to assess the therapeutic effects. Therapeutic effect in the treatment group was better than that in the control group in all the indexes observed, showing statistical significance (all P <0.05). Early intervention of HT-C could improve clinical symptom, promote the functional recovery and intellectual development in children HIE, and also could reduce or prevent the sequelae occurrence of the nervous system in them.

    Haemodialysis patients are at risk of gram-positive bacteraemia and commonly require intravenous vancomycin. Intravenously administered vancomycin is primarily excreted by the kidney and exhibits complex pharmacokinetics in haemodialysis patients; achieving therapeutic levels can be challenging. An audit in our unit showed current practises of vancomycin administration resulted in a high proportion of sub-therapeutic levels. A new protocol was developed with fixed weight-based loading and subsequent dosing guided by pre-dialysis levels, target levels were 10-20mg\\/L. Its effectiveness was prospectively evaluated between 24th September 2012, and 8th February 2013. During this period 25 patients commenced vancomycin, 15 were included. In total, 112 vancomycin levels were taken, 94 (84%) were therapeutic, this was a significant improvement compared to previous practise (odds ratio 5.4, CI 3.1-9.4, p < 0.0001). In conclusion, our study shows this protocol can consistently and reliably achieve therapeutic vancomycin levels

    Curcumin (diferuloylmethane) is a polyphenol derived from the Curcuma longa plant. Curcumin has been used extensively in Ayurvedic medicine, as it is nontoxic and exhibits a variety of therapeutic properties, including antioxidant, analgesic, anti-inflammatory and antiseptic activities. Recently, certain studies have indicated that curcumin may exert anticancer effects in a variety of biological pathways involved in mutagenesis, apoptosis, tumorigenesis, cell cycle regulation and metastasis. The present study reviewed previous studies in the literature, which support the therapeutic activity of curcumin in cancer. In addition, the present study elucidated a number of the challenges concerning the use of curcumin as an adjuvant chemotherapeutic agent. All the studies reviewed herein suggest that curcumin is able to exert anti-inflammatory, antiplatelet, antioxidative, hepatoprotective and antitumor activities, particularly against cancers of the liver, skin, pancreas, prostate, ovary, lung and head neck, as well as having a positive effect in the treatment of arthritis.

    To compare the differences of therapeutic effect of chronic fatigue syndrome treated with the combined therapy of coiling dragon needling and cupping on back and the western medicine therapy with Prednisone. Seventy-two cases were randomly divided into an acupuncture and cupping group (37 cases) and a Prednisone group (35 cases). In acupuncture and cupping group, Jiaji (EX-B 2) points of T1--L5 were applied with coiling dragon needling (once a day), combined with moving cupping on back (once every two days); in Prednisone group, Prednisone tablets were orally taken for 10 mg at 8:00 am. Seven days made one course, and 2 courses were carried on totally. FS-14 scale and BELL's chronic fatigue syndrome integral table were applied to evaluate the fatigue degree of patients before and after treatment, and the therapeutic effects of both groups were compared. After one course of treatment, the BELL's scores of both groups were obviously improved (both P 0.05); after two courses of treatment, the BELL's score in acupuncture and cupping group improved more obviously than that in Prednisone group, and the total effective rate of 91.9% (34/37) in acupuncture and cupping group was superior to that of 71.4% (25/35) in Prednisone group (P cupping on back is positive, superior to that of Prednisone with oral administration.

    Tumor irradiation of the head-neck area is accompanied by the development of a so-called radiation caries in the treated patients. In spite of conservative therapeutic measures, the process results in tooth destruction. The present study investigated the effects of irradiation on the demineralization and remineralization of the dental tissue. For this purpose, retained third molars were prepared and assigned either to a test group, which was exposed to fractional irradiation up to 60 Gy, or to a non-irradiated control group. Irradiated and non-irradiated teeth were then demineralized using acidic hydroxyl-cellulose gel; afterwards the teeth were remineralized using either Bifluorid12 {sup registered} or elmex gelee {sup registered}. The nanoindentation technique was used to measure the mechanical properties, hardness and elasticity, of the teeth in each of the conditions. The values were compared to the non-irradiated control group. Irradiation decreased dramatically the mechanical parameters of enamel and dentine. In non-irradiated teeth, demineralization had nearly the same effects of irradiation on the mechanical properties. In irradiated teeth, the effects of demineralization were negligible in comparison to non-irradiated teeth. Remineralization with Bifluorid12 {sup registered} or elmex gelee {sup registered} led to a partial improvement of the mechanical properties of the teeth. The enamel was more positively affected, by remineralization than the dentine. (orig.)

  17. The special effects of hypnosis and hypnotherapy: A contribution to an ecological model of therapeutic change.

    There is ample evidence that hypnosis enhances the effectiveness of psychotherapy and produces some astounding effects of its own. In this paper, the effective components and principles of hypnosis and hypnotherapy are analyzed. The "special" hypnotic and hypnotherapeutic effects are linked to the fact that the ecological requirements of therapeutic change are taken into account implicitly and/or explicitly when working with hypnotic trances in a therapeutic setting. The hypnotic situation is described--theoretically and in case examples--as a therapeutic modality that gratifies and aligns the basic emotional needs to feel autonomous, related, competent, and oriented. It is shown how the hypnotic relationship can help promote a sound ecological balance between these needs--a balance that is deemed to be a necessary prerequisite for salutogenesis. Practical implications for planning hypnotherapeutic interventions are discussed.

    Exercise therapy is an important part of symptomatic and supportive treatment in patients with multiple sclerosis (PwMS). According to the literature, equine-assisted therapies--such as therapeutic horseback riding (THR) and hippotherapy (HT)--are exercise therapies that can have positive physical effects on coordination, muscle tone, postural alignment, stiffness/flexibility, endurance and strength, correcting abnormal movement patterns and improving gait and balance. While HT is known to have a positive effect on balance in PwMS, data about THR are limited. The aim of the present work was to determine the effect of THR on the balance and gait of ambulatory PwMS. Twenty-seven PwMS were included in the study. Patients were divided into two groups: 12 underwent THR and 15 traditional physiotherapy (for both groups, two series of 10 weekly sessions were performed). Before and after the study period, the following outcome measures were applied: Extended Disability Status Scale (EDSS), Barthel Index, Tinetti Performance-Oriented Mobility Assessment (POMA). In addition, patients of the THR group underwent a gait analysis to assess spatiotemporal gait parameters and ground reaction forces. The THR group showed a significant improvement in POMA scores (p<0.005) and two gait parameters: stride time (p<0.04) and ground reaction forces (p<0.01). No statistically significant change was found in the control group. The results of the study show that THR can improve balance and gait of ambulatory PwMS. Findings are preliminary, but promising and in line with the recent literature.

  19. Effects of certain therapeutic factors on facial development in isolated cleft palate.

    Roentgencephalometry was used during the investigation of the effects of some therapeutic factors on the growth and development of the jaws in 64 adult males with an isolated cleft palate repaired by pushback. The anterior growth of the maxilla was not related to the age at the time of surgery or to orthodontic therapy with removable appliances. A small number of individuals operated during adolescence had also a shorter depth of the maxilla similarly as patients operated upon during early childhood. Anterior crossbite developed mostly in patients with reduced proclination of the upper alveolar process, while, on the contrary, a retrusion of the maxilla played no essential part. This observation proves useful for the prediction of the development of this malocclusion. The angle of sagittal jaw relations does not represent necessarily a valid criterion of the development of the jaws. In the presence of an overbite retrusion of the maxilla is associated with a retroposition of the mandible and thus the angle of sagittal jaw relations remains unchanged. Thus overbite represents an effective mechanism acting on the position of the mandible. A differentiated approach for the determination of the age of choice at the time of palate surgery according to the type and extent of the cleft is proposed.

    Schistosoma haematobium ( S. haematobium ) infection has been found to be strongly associated with bladder cancer, which necessitates for discover of a natural new therapeutic agent. The aim of this study was to evaluate the therapeutic effect of Arctium lappa seed extract in S. haematobium associated kidney disturbance. Forty male albino mice were used and divided into four equal groups; group 1 control includes non-infected healthy mice, groups 2, 3 and 4 subcutaneous infected with S. haematobium cercariae. Groups 3 co-treated daily with oral dose of A. lappa seed extract (300 mg/kg, bwt) for 15 days in the same time of S. haematobium infection. Groups 4 post-treated daily for 15 days with oral dose of A. lappa seed extract (300 mg/kg, bwt) after 15 days of S. haematobium infection. The results obtained revealed that S. haematobium significantly decreased kidney weight and serum sodium, potassium and chloride, but increased urinary volume, urinary excretion of sodium, potassium and chloride, serum urea, creatinine and uric acid. Schistosoma haematobium also significantly decreased kidney superoxide dismutase, glutathione peroxidase and reduced glutathione levels while increased kidney lipid peroxidation level. Co- and post-treatment with A. lappa seed extract restore all the above parameters to approach the normal values. These results were supported with histopathological examinations. In conclusion, A. lappa seed extract has therapeutic effect in kidney disturbance caused by S. haematobium where co-treatment of A. lappa seed extract was more effective than post-treatment of the extract.

  1. Human Factor in Therapeutic Relationship

    Full Text Available herapeutic relationship is a professional relationship that has been structured based on theoretical props. This relationship is a complicated, wide and unique relationship which develops between two people, where both sides' personality and attitudes inevitably interfere. Therapist-client relationship experienced through transference and counter transference, especially in psychodynamic approaches, is accepted as the main aspect of therapeutic process. However, the approaches without dynamic/deterministic tendency also take therapist-client relationship into account seriously and stress uniqueness of interaction between two people. Being a person and a human naturally sometimes may negatively influence the relationship between the therapist and client and result in a relationship going out of the theoretical frame at times. As effective components of a therapeutic process, the factors that stem from being human include the unique personalities of the therapist and the client, their values and their attitude either made consciously or subconsciously. Literature has shown that the human-related factors are too effective to be denied in therapeutic relationship process. Ethical and theoretical knowledge can be inefficient to prevent the negative effects of these factors in therapeutic process at which point a deep insight and supervision would have a critical role in continuing an acceptable therapeutic relationship. This review is focused on the reflection of some therapeutic factors resulting from being human and development of counter transference onto the therapeutic process.

    This paper reports on inpatient treatment of addicts. Attention is paid to the Therapeutic Community (TC) model employed with alcoholics. A sample of 881 patients was assessed at intake and was followed up. The results demonstrate that the patients improved on a variety of outcome measures. Some associations were found between patient variables and improvement. Treatment variables predicting a positive outcome were sustained treatment in a TC and attending AA meetings. The relative efficacy of TCs, originally created by drug users, holds for alcoholics as well. It is concluded that an important precondition to a positive treatment outcome is the continuity of the treatment process. Pursuing that continuity seems to be an excellent mediate goal for both addicts and treatment personnel.

    the effectiveness of online counseling in decreasing the magnitude of reported symptoms, with a direct positive impact on the improvement of daily functioning and on future relapses. However, the usefulness of developing a therapeutic relationship through internet connection is being criticized by a group of clinicians, with their main arguments revolving around spatiotemporal issues and the reliability of incoming information. Some other researchers correlate the therapeutic alliance concluded in the context of electronic communication with a positive therapeutic effect. The data on the effectiveness of online practice are not sufficient to draw a definite conclusion. In an era of direct and rapid communication, it is imperative to encourage further research, for the determination of optimal conditions with respect to the practice of internet-delivered psychotherapy and the patients' well being as a result of treatment.

    Therapeutic touch is a complementary treatment directed toward the balance of the energy field surrounding living beings. This study's aim was to investigate the effect of therapeutic touch on wound area contraction and fibroblast proliferation in rat skin. This study was conducted using 24 male Wistar rats with dorsal wounds of diameter 8mm. The rats were divided into the following two groups: a control group: in this, the wounds were sanitized with filtered water and neutral-pH soap and a treatment group: in this, the wounds were sanitized as in the control group but the rats also underwent to daily sessions of therapeutic touch. Wound area was measured on days 1, 4, and 7 using imagelab software, version 2.4 R.C. On days 4 and 7, six animals in each group were euthanized so that the lesioned tissue could be collected for fibroblast counts and histological evaluations. On days 1 and 4, wound areas were similar in both groups. Moreover, no significant differences in fibroblast counts were observed on day 4. On day 7, however, fibroblast counts were significantly higher in the treated group than in the control group, with a subsequent wound shrinkage. These data indicate that therapeutic touch may accelerate wound repair, possibly by increasing fibroblast activity. Copyright © 2017 Elsevier Inc. All rights reserved.

    Avastin is the monoclonal antibody for vascular endothelial growth factor (VEGF). This study aimed to investigate therapeutic effect of Avastin on type II collagen-induced arthritis. Type II chicken collagen was injected into the tails of Wistar rats, and 60 modeled female rats were randomly divided into three groups (n = 20): Avastin group, Etanercept group, and control group. Arthritis index and joint pad thickness were scored, and the pathology of back metapedes was analyzed. The results showed that compared to control group, the arthritis index, target-to-non-target ratio, synovial pathological injury index, serum levels of VEGF and tumor necrosis factor alpha, and VEGF staining were decreased significantly 14 days after Avastin or Etanercept treatment, but there were no significant differences between Avastin group and Etanercept group. These data provide evidence that Avastin exhibits similar effects to Etanercept to relieve rheumatoid arthritis in rat model and suggest that Avastin is a promising therapeutic agent for rheumatoid arthritis.

    Some molecules enriched in damaged organs can contribute to tissue repair by stimulating the mobilization of stem cells. These so-called “priming” factors include bioactive lipids, complement components, and cationic peptides. However, their therapeutic significance remains to be determined. Here, we show that priming of mesenchymal stromal/stem cells (MSCs) with ceramide-1 phosphate (C1P), a bioactive lipid, enhances their therapeutic efficacy in pulmonary artery hypertension (PAH). Human bone marrow (BM)-derived MSCs treated with 100 or 200 μM C1P showed improved migration activity in Transwell assays compared with non-primed MSCs and concomitantly activated MAPK p42/44 and AKT signaling cascades. Although C1P priming had little effect on cell surface marker phenotypes and the multipotency of MSCs, it potentiated their proliferative, colony-forming unit-fibroblast, and anti-inflammatory activities. In a monocrotaline-induced PAH animal model, a single administration of human MSCs primed with C1P significantly attenuated the PAH-related increase in right ventricular systolic pressure, right ventricular hypertrophy, and thickness of α-smooth muscle actin-positive cells around the vessel wall. Thus, this study shows that C1P priming increases the effects of MSC therapy by enhancing the migratory, self-renewal, and anti-inflammatory activity of MSCs and that MSC therapy optimized with priming protocols might be a promising option for the treatment of PAH patients. - Highlights: • Human BM-derived MSCs primed with C1P have enhanced migratory activity. • C1P primed MSCs increase proliferation, self-renewal, and anti-inflammatory capacity. • C1P priming enhances the therapeutic capacity of MSCs in a PAH animal model.

    Ehen refractory to optimal medical treatment cardiogenic pulmonary edema requires mechanical ventilation as a last therapeutic resource. In recent years an increasing number of authors reported their experience in the management of acute or subacute respiratory failure with non-invasive mechanical ventilation by nasal mask. Encouraged by the first promising results reported in literature we experimented this new therapeutic tool in a first group of seven elderly patients (mean age: 76.57--range: 65-89); they all had been admitted for severe cardiogenic pulmonary edema unresponsive to maximal doses of the conventional drugs available for treating acute decompensated heart failure. The enrolled patients were treated with intermittent ventilation administered by nasal mask at selected values of inspiratory positive airway pressure (IPAP) that were comprised between 10 and 20 cm H2O. At the same time an expiratory positive airway pressure (EPAP) at values comprised between 3 and 8 cm H2O was applied. Ventilation was continued for variable periods of 3-24 hours until acceptable values of PaO2 and PaCO2 were obtained. The ventilation modality was spontaneous, spontaneous-time or timed depending on the patients' level of consciousness at starting time. A good short-term outcome was achieved in all the patients regardless of the ventilation modality applied. The main blood gas alteration was severe hypercapnia with acidosis in three patients, while the other four presented critical hypoxemia unresponsive to simple oxygen supply even if delivered by high-flow Venturi mask. Four of our seven patients were discharged from hospital in satisfactory haemodynamic conditions; the remaining three died during hospitalization from refractory heart failure. In this our preliminary experience the therapeutic approach with nasal positive pressure ventilation (NPPV) and EPAP proved to be very effective to improve the signs and symptoms of acute refractory cardiogenic pulmonary edema as

    Full Text Available Rationale: Current first-line treatments for stress-related disorders such as Major Depressive Disorder (MDD act on monoaminergic systems and take weeks to achieve a therapeutic effect with poor response and low remission rates. Recent research has implicated the GABAergic system in the pathophysiology of depression, including deficits in interneurons targeting the dendritic compartment of cortical pyramidal cells. Objectives: The present study evaluates whether SH-053-2'F-R-CH3 (denoted α5-PAM, a positive allosteric modulator selective for α5-subunit containing GABAA receptors found predominantly on cortical pyramidal cell dendrites has anti-stress effects. Methods: Female and male C57BL6/J mice were exposed to unpredictable chronic mild stress (UCMS and treated with α5-PAM acutely (30 minutes prior to assessing behavior or chronically before being assessed behaviorally. Results: Acute and chronic α5-PAM treatments produce a pattern of decreased stress-induced behaviors (denoted as behavioral emotionality across various tests in female, but not in male mice. Behavioral Z-scores calculated across a panel of tests designed to best model the range and heterogeneity of human symptomatology confirmed that acute and chronic α5-PAM treatments consistently produce significant decreases in behavioral emotionality in several independent cohorts of females. The behavioral responses to α5-PAM could not be completely accounted for by differences in drug brain disposition between female and male mice. In mice exposed to UCMS, expression of the Gabra5 gene was increased in the frontal cortex after acute treatment and in hippocampus after chronic treatment with α5-PAM in females only, and these expression changes correlated with behavioral emotionality. Conclusions: We showed that acute and chronic positive modulation of α5 subunit-containing GABAA receptors elicit anti-stress effects in a sex-dependent manner, suggesting novel therapeutic modalities.

  12. Exosomes and Their Therapeutic Potentials of Stem Cells

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Exosomes, a group of vesicles originating from the multivesicular bodies (MVBs, are released into the extracellular space when MVBs fuse with the plasma membrane. Numerous studies indicate that exosomes play important roles in cell-to-cell communication, and exosomes from specific cell types and conditions display multiple functions such as exerting positive effects on regeneration in many tissues. It is widely accepted that the therapeutic potential of stem cells may be mediated largely by the paracrine factors, so harnessing the paracrine effects of stem and progenitor cells without affecting these living, replicating, and potentially pluripotent cell populations is an advantage in terms of safety and complexity. Ascending evidence indicated that exosomes might be the main components of paracrine factors; thus, understanding the role of exosomes in each subtype of stem cells is far-reaching. In this review, we discuss the functions of exosomes from different types of stem cells and emphasize the therapeutic potentials of exosomes, providing an alternative way of developing strategies to cure diseases.

    To investigate the therapeutic effects of bronchoalveolar lavage (BAL) with either diluted surfactant (SBAL) or perfluorochemical liquid (PBAL), followed by either conventional mechanical ventilation (CMV) or partial liquid ventilation (PLV), on lung injury and proinflammatory cytokine production induced by meconium aspiration in newborn piglets. A prospective, randomized, experimental study. An animal research laboratory at a medical center. Anesthetized and mechanically ventilated newborn piglets (n = 27). The animals were instilled with 3-5 mL/kg 25% human meconium via an endotracheal tube to induce meconium aspiration syndrome (MAS). After stabilization, animals were randomly assigned to either CMV group (no BAL) or one of the treatment groups (SBAL-CMV, SBAL-PLV, PBAL-CMV, and PBAL-PLV). Cardiopulmonary variables were monitored, and interleukin-1beta and interleukin-6 content of the serum and lung tissue was measured. The animals without any treatment (CMV group) displayed the worst outcome; the animals in the PBAL-PLV group had the best gas exchange, lung compliance, and least pulmonary damage; and the SBAL-CMV, PBAL-CMV, and SBAL-PLV groups had intermediate effects. The serum interleukin-1beta concentration of the CMV group was significantly higher than all other groups over time (p CMV group and lowest in the PBAL-PLV group. Initial therapeutic BAL and therapeutic BAL followed by PLV with the same perfluorochemical liquid provided significant therapeutic effects in treating an animal model with severe MAS and therefore warrant consideration in cases that are intractable to other therapies.

    In two experiments that we conducted with adult (Experiment 1) and child (Experiment 2) participants, we experimentally controlled the eyes' first fixation in the word using a variable viewing-position technique in a classical all-letter-coloring Stroop procedure. We explored the impact of initial-fixation position (optimal viewing position [OVP] vs. end of the word) on the magnitude of Stroop effects (both interference and facilitation). The results showed that both interference and facilitation effects were reduced when the first fixation was located at the end of the word rather than at the OVP. These data make a new contribution to the study of the role of low-level processes in Stroop effects and add support to the growing body of research indicating that oculomotor processes can act as moderators of cognitive processes in the determination of Stroop effects.

    Full Text Available The purpose of this article is to research and retrieve patent information regarding the therapeutic use of truffles. Truffles have a unique value as a foodstuff and impact positively on human health and well-being. They are applied in such industries as the pharmaceutical industry and the cosmetic industry. Patent documentation available in the Espacenet network and the Patentscope service were analyzed by key word and patent specifications were examined to describe state of the art and to identify scientific research trends in therapeutic applications of truffles. Medicinal properties of truffles such as the anticancer or cardiovascular effect, a reduction in blood lipids, immunological resistance and increased energy were identified. Other therapeutic benefits include sedative action, prevention of hormonal imbalances in women, pre-menopause symptom relief, senile urethritis and prostate disorders, sleep disorders and increased absorption of calcium from milk. Truffles can also be used to alleviate symptoms of milk intolerance such as diarrhoea or bloating, to ease rheumatic pains and to treat and prevent further development or recurrence of senile cataract.

    The adolescent drug problem places a huge toll on society and a heavy burden on the criminal justice system. Research regarding the benefits of therapeutic community (TC) treatment for adolescents has shown it to be effective. Despite the ability of therapeutic communities to lower drug relapse and reduce criminality, a great deal remains unknown…

    Full Text Available The article discusses the problem of emotional significance of a positive form of speech. Based on the methodology of emotions linguistics, linguoecology, communicative linguistics and the methods of description, comparison and discourse analysis, the author distinguishes some types of speech situations that demonstrate visible differences between positive expression of emotions and their content and the pragmatic effect. The difference between the notions of “positive communication” and “positive form of communication” is demonstrated. Special attention is given to the following types of positive emotional communication: tolerant emotional communication, emotional emphasis, emotional neglect, and emotional tabooing. The utterances in situations of real and textual communication demonstrate negative effects of statements expressed in a positive form and identify the specifics of positive forms of emotional communication in comparison with rational communication.

    Full Text Available Sepsis is one of the major causes of death and is the biggest obstacle preventing improvement of the success rate in curing critical illnesses. Currently, isotonic solutions are used in fluid resuscitation technique. Several studies have shown that hypertonic saline applied in hemorrhagic shock can rapidly increase the plasma osmotic pressure, facilitate the rapid return of interstitial fluid into the blood vessels, and restore the effective circulating blood volume. Here, we established a rat model of sepsis by using the cecal ligation and puncture approach. We found that intravenous injection of hypertonic saline dextran (7.5% NaCl/6% dextran after cecal ligation and puncture can improve circulatory failure at the onset of sepsis. We found that the levels of tumor necrosis factor-α, interleukin-1β, interleukin-6 and intracellular adhesion molecule 1 levels in the lung tissue of cecal ligation and puncture rats treated with hypertonic saline dextran were significantly lower than the corresponding levels in the control group. We inferred that hypertonic saline dextran has a positive immunoregulatory effect and inhibits the overexpression of the inflammatory response in the treatment of sepsis. The percentage of neutrophils, lung myeloperoxidase activity, wet to dry weight ratio of lung tissues, histopathological changes in lung tissues, and indicators of arterial blood gas analysis was significantly better in the hypertonic saline dextran-treated group than in the other groups in this study. Hypertonic saline dextran-treated rats had significantly improved survival rates at 9 and 18 h compared to the control group. Our results suggest that hypertonic saline dextran plays a protective role in acute lung injury caused after cecal ligation and puncture. In conclusion, hypertonic/hyperoncotic solutions have beneficial therapeutic effects in the treatment of an animal model of sepsis.

    Selective androgen receptor modulators (SARMS) bind to the androgen receptor and demonstrate anabolic activity in a variety of tissues; however, unlike testosterone and other anabolic steroids, these nonsteroidal agents are able to induce bone and muscle growth, as well as shrinking the prostate. The potential of SARMS is to maximise the positive attributes of steroidal androgens as well as minimising negative effects, thus providing therapeutic opportunities in a variety of diseases, including muscle wasting associated with burns, cancer, end-stage renal disease, osteoporosis, frailty and hypogonadism. This review summarises androgen physiology, the current status of the R&D of SARMS and potential therapeutic indications for this emerging class of drugs.

    The joint administration of magnesium aspartate and adenosine monophosphate, injected on days 1 to 4 post radiation, has been found to exert stimulatory effects on the recovery of hemopoietic functions in sublethally gamma-irradiated mice. These therapeutical effects were enhanced in animals protected by peroral administration of cystamine. The treatment scheme used did not modify survival of lethally irradiated mice. The therapeutic effects of magnesium aspartate and adenosine monophosphate in sublethally irradiated mice are explained by the stimulatory action of these drugs on the cell adenylate cyclase system, which influences the erythropoietic functions.

    Full Text Available The present study aims at examining the effects of argan oil on the three main cardiovascular risk factors associated with metabolic syndrome (hypertension, insulin resistance and obesity and on one of its main complications, neuropathic pain. Male Sprague-Dawley rats had free access to a drinking solution containing 10% d-glucose or tap water for 12 weeks. The effect of argan oil was compared to that of corn oil given daily by gavage during 12 weeks in glucose-fed rats. Glucose-fed rats showed increases in systolic blood pressure, epididymal fat, plasma levels of triglycerides, leptin, glucose and insulin, insulin resistance, tactile and cold allodynia in association with a rise in superoxide anion production and NADPH oxidase activity in the thoracic aorta, epididymal fat and gastrocnemius muscle. Glucose-fed rats also showed rises in B1 receptor protein expression in aorta and gastrocnemius muscle. Argan oil prevented or significantly reduced all those anomalies with an induction in plasma adiponectin levels. In contrast, the same treatment with corn oil had a positive impact only on triglycerides, leptin, adiponectin and insulin resistance. These data are the first to suggest that argan oil is an effective nutri-therapeutic agent to prevent the cardiovascular risk factors and complications associated with metabolic syndrome.

    2018-01-01

    Bereaved individuals are increasingly considered at risk for negative psychological and physiological outcomes. Visual art modalities are often incorporated into grief therapy interventions, and clinical application of art therapy techniques with the bereaved has been widely documented. Although clinicians and recipients of these interventions advocate for their helpfulness in adapting to bereavement, research investigating the efficacy of visual art modalities has produced equivocal results and has not yet been synthesized to establish empirical support across settings. Accordingly, this review critically evaluates the existent literature on the effectiveness of visual art modalities with the bereaved and offers suggestions for future avenues of research. A total of 27 studies were included in the current review. Meta-analysis was not possible because of clinical heterogeneity and insufficient comparable data on outcome measures across studies. A narrative synthesis reports that therapeutic application of visual art modalities was associated with positive changes such as continuing bonds with the deceased and meaning making. Modest and conflicting preliminary evidence was found to support treatment effectiveness in alleviating negative grief symptoms such as general distress, functional impairment, and symptoms of depression and anxiety.

  5. Polymer therapeutics and the EPR effect.

    Science.gov (United States)

    Maeda, Hiroshi

    History of the EPR (enhanced permeability and retention) effect is discussed, which goes back to the analyses of molecular pathology in bacterial infection and edema (extravasation) formation. The first mediator we found for extravasation was bradykinin. Later on, were found nitric oxide and superoxide, then formation of peroxynitrite, that activates procollagenase. In this inflammatory setting many other vascular mediators are involved that are also common to cancer vasculature. Obviously cancer vasculature is defective architechtally, and this makes macromolecular drugs more permeable through the vascular wall. The importance of this pathophysiological event of EPR effect can be applied to macromolecular drug-delivery, or tumor selective delivery, which takes hours to achieve in the primary as well as metastatic tumors, not to mention of the inflamed tissues. The retention of the EPR means that such drugs will be retained in tumor tissues more than days to weeks. This was demonstrated initially, and most dramatically, using SMANCS, a protein-polymer conjugated-drug dissolved in lipid contrast medium (Lipiodol) by administering intraarterially. For disseminating the EPR concept globally, or in the scientific community, Professor Ruth Duncan played a key role at the early stage, as she worked extensively on polymer- therapeutics, and knew its importance.

    The consumption of marijuana extracted from Cannabis sativa and indica plants involves an important cultural impact in Mexico. Their psychological stimulatory effect is widely recognized; their biochemical and molecular components interact with CB1 and CB2 (endocannabinoid system) receptors in various central nervous system structures (CNS) and immune cells. The psychoactive element Δ-9-tetrahydrocannabinol (THC) can be reproduced synthetically. Systematic reviews show evidence of therapeutic effectiveness of therapeutic marijuana only for certain symptoms of multiple sclerosis (spasticity, spasms and pain), despite attempts for its widespread use, including refractory childhood epilepsy. Evidence indicates significant adverse effects of smoked marijuana on the structure, functioning and brain connectivity. Cannabis exposure during pregnancy affects fetal brain development, potentially leading to later behavioral problems in children. Neuropsychological tests and advanced imaging techniques show involvement in the learning process in adolescents with substance use. Also, marijuana increases the cognitive impairment in patients with multiple sclerosis. Social and ethical consequences to legally free marijuana for recreational use may be deleterious transcendentally. The medicinal or psychoactive cannabinol no addictive effect requires controlled proven efficacy and safety before regulatory approval studies.

    The neurotrophic hypothesis has become the favorite model to explain the antidepressant properties of electroconvulsive therapy (ECT). It is based on the assumption that a restoration of previously defective neural networks drives therapeutic effects. Recent data in rather young patients suggest that neurotrophic effects of ECT might be detectable by diffusion tensor imaging. We here aimed to investigate whether the therapeutic response to ECT necessarily goes along with mesoscopic effects in gray matter (GM) or white matter (WM) in our patients in advanced age. Patients (n = 21, 15 males and 7 females) suffering from major depressive disorder were treated with ECT. Before the start of treatment and after the completion of the index series, they underwent magnetic resonance imaging, including a diffusion-weighed sequence. We used voxel-based morphometry to assess GM changes and tract-based spatial statistics and an SPM-based whole-brain analysis to detect WM changes in the course of treatment. Patients significantly improved clinically during the course of ECT. This was, however, not accompanied by GM or WM changes. This result challenges the notion that mesoscopic brain structure changes are an obligatory prerequisite for the antidepressant effects of ECT.

  8. One target, different effects: a comparison of distinct therapeutic antibodies against the same targets.

    To date, more than 30 antibodies have been approved worldwide for therapeutic use. While the monoclonal antibody market is rapidly growing, the clinical use of therapeutic antibodies is mostly limited to treatment of cancers and immunological disorders. Moreover, antibodies against only five targets (TNF-α, HER2, CD20, EGFR, and VEGF) account for more than 80 percent of the worldwide market of therapeutic antibodies. The shortage of novel, clinically proven targets has resulted in the development of many distinct therapeutic antibodies against a small number of proven targets, based on the premise that different antibody molecules against the same target antigen have distinct biological and clinical effects from one another. For example, four antibodies against TNF-α have been approved by the FDA -- infliximab, adalimumab, golimumab, and certolizumab pegol -- with many more in clinical and preclinical development. The situation is similar for HER2, CD20, EGFR, and VEGF, each having one or more approved antibodies and many more under development. This review discusses the different binding characteristics, mechanisms of action, and biological and clinical activities of multiple monoclonal antibodies against TNF-α, HER-2, CD20, and EGFR and provides insights into the development of therapeutic antibodies.

    Ready-to-use-therapeutic foods (RUTF) are an important component of the effective outpatient treatment of severe wasting because most of the child deaths in the world especially in developing countries is due to malnutrition. The objective of the study was to evaluate the effectiveness and acceptability of ready to use therapeutic food among malnourished children in a tertiary care hospital. Methods: An observational exploratory study based on sixty subjects with 3-120 months of age, malnourished children were chosen by universal sampling from Children Hospital Lahore, Pakistan, during the time period 1st September 2012 to 30th November 2012 with the approval of ethical committee. The study tool for investigation was a well-structured questionnaire. Results: The highest proportion of malnourished children belonged to urban areas (71.67%) and age group <24 months (65%). The effect of RUTF on weight for height and weight for age Z score from baseline to the end of follow-up was statistically significant (Paired sample t-test) (p=0.000, 0.000) but there was no significant effect of RUTF on height for age (p-value=0.14).The acceptance of food among patients was good, the proportion of patient was higher who consumed ready to use therapeutic food easily (70%), percentage of vomiting (16.7%) and complaints of diarrhoea (46.7%) after taking RUTF was less in patients. All mothers were satisfied from ready to use therapeutic foods (100%). Conclusion: Malnourished children gained weight after the short term supplementation of ready to use therapeutic food but had no significant effect on height of the patients. Its acceptability in term of taste, amount consumes and demand was good. Mother's perception was also satisfactory regarding these foods. (author)

    Including children with emotional and behavioral needs in mainstream school systems leads to growing concern about the increasing number of violent and nonviolent conflicts. Schools must adapt to this evolution and adopt a more therapeutic dimension. This paper explores the possibility of integrating school-based and therapeutic conflict management models and compares two management models: a school-based conflict management program. Teaching Students To Be Peacemakers; and a therapeutic conflict management program, Life Space Crisis Intervention. The authors conclude that integration might be possible, but depends on establishing a positive school atmosphere, the central position of the teacher, and collaborative and social learning for pupils. Further implementation of integrated conflict management models can be considered but must be underpinned by appropriate scientific research.

    The therapeutic effects of the plant species used in homeopathy have never been subjected to systematic analysis. A survey of the various Materiae Medicae shows that over 800 plant species are the source of medicines in homeopathy. As these medicines are considered related to one another with respect to their therapeutic effects for treating similar symptoms, the aim is to classify and map them using the concept of homology. This involves placing the discipline of homeopathy into a comparative framework using these plant medicines as taxa, therapeutic effects as characters, and contemporary cladistic techniques to analyse these relationships. The results are compared using cladograms based on different data sets used in biology (e.g. morphological characters and DNA sequences) to test whether similar cladistic patterns exist among these medicines. By classifying the therapeutic actions, genuine homologies can be distinguished from homoplasies. As this is a comparative study it has been necessary first to update the existing nomenclature of the plant species in the homeopathic literature in line with the current International Code of Botanical Nomenclature.

    Full Text Available Objective: To compare the randomized controlled trial evidence for therapeutic effects on walking of functional electrical stimulation and ankle foot orthoses for foot drop caused by central nervous system conditions. Data sources: MEDLINE, CINAHL, Cochrane Central Register of Controlled Trials, REHABDATA, PEDro, NIHR Centre for Reviews and Dissemination, Scopus and clinicaltrials.gov. Study selection: One reviewer screened titles/abstracts. Two independent reviewers then screened the full articles. Data extraction: One reviewer extracted data, another screened for accuracy. Risk of bias was assessed by 2 independent reviewers using the Cochrane Risk of Bias Tool. Data synthesis: Eight papers were eligible; 7 involving participants with stroke and 1 involving participants with cerebral palsy. Two papes reporting different measures from the same trial were grouped, resulting in 7 synthesized randomized controlled trials (n= 464. Meta-analysis of walking speed at final assessment (p = 0.46, for stroke participants (p = 0.54 and after 4–6 weeks’ use (p = 0.49 showed equal improvement for both devices. Conclusion: Functional electrical stimulation and ankle foot orthoses have an equally positive therapeutic effect on walking speed in non-progressive central nervous system diagnoses. The current randomized controlled trial evidence base does not show whether this improvement translates into the user’s own environment or reveal the mechanisms that achieve that change. Future studies should focus on measuring activity, muscle activity and gait kinematics. They should also report specific device details, capture sustained therapeutic effects and involve a variety of central nervous system diagnoses.

    Full Text Available Leishmaniasis is an important neglected tropical disease, affecting more than 12 million people worldwide. The available treatments are not well tolerated and present diverse side effects in patients, justifying the search for new therapeutic compounds. In the present study, the therapeutic potential and toxicity of ursolic acid (UA, isolated from the leaves of Baccharis uncinella C. DC. (Asteraceae, were evaluated in experimental visceral leishmaniasis. To evaluate the therapeutic potential of UA, hamsters infected with L. (L. infantum were treated daily during 15 days with 1.0 or 2.0 mg UA/kg body weight, or with 5.0 mg amphotericin B/kg body weight by intraperitoneal route. Fifteen days after the last dose, the parasitism of the spleen and liver was stimated and the main histopathological alterations were recorded. The proliferation of splenic mononuclear cells was evaluated and IFN-γ, IL-4, and IL-10 gene expressions were analyzed in spleen fragments. The toxicity of UA and amphotericin B were evaluated in healthy golden hamsters by histological analysis and biochemical parameters. Animals treated with UA had less parasites in the spleen and liver when compared with the infected control group, and they also showed preservation of white and red pulps, which correlate with a high rate of proliferation of splenic mononuclear cells, IFN-γ mRNA and iNOS production. Moreover, animals treated with UA did not present alterations in the levels of AST, ALT, creatinine and urea. Taken together, these findings indicate that UA is an interesting natural compound that should be considered for the development of prototype drugs against visceral leishmaniasis.

    Walling, D P; Levine, R E

    1997-01-01

    The unique relationship between hypnotist and subject has been theorized as one explanation for the effectiveness of hypnosis. This relationship carries a power differential, present in most therapeutic relationships, but accentuated by hypnosis. The power differential is sometimes perceived as the ability of the hypnotist to control the subject. Perceptions of hypnosis offered by stage hypnotists, the popular media, and some clinicians perpetuate the notion that the hypnotist has the ability to exert undue influence upon the client. The present article examines the relationship between hypnotist and subject focusing on issues of power and control. The authors examine the unique dynamics accompanying the use of hypnosis and their impact on the therapeutic dyad. Evidence is offered demonstrating the power differential, and how this differential can serve as either a positive or negative agent of change. Therapists should be aware of the dynamics created by using hypnosis. Implications for training therapists in the use of hypnosis are suggested.

  1. Psychiatric patients' satisfaction in the therapeutic residence services: A positive experience of psychiatric deinstitutionalization

    Full Text Available This study investigated the satisfaction level of psychiatric patients in the therapeutic residential services of Barbacena-MG. Total population comprised 154 individuals, of which 45 were sampled. Subjects were interviewed with the SATIS-BR scale and a sociodemographic questionnaire. Results showed a high degree of satisfaction with the service for the global score and its three dimensions staff competence and understanding, help received, infrastructure. Results were not related to sociodemographic and clinical variables analyzed individually. Multivariate analysis indicated higher satisfaction for literate patients and for those that underwent some other form of treatment (e.g., hydrogymnastics and fitness activities besides medications or occupational therapy. We conclude that the therapeutic residence services appear to be a viable alternative for mental health public policy, from the patients' perspective.

    Shifting current drug discovery tide from 'finding new drugs' to 'screening natural products' may be helpful for overcoming the 'more investment, fewer drugs' challenge. Traditional Chinese medicine (TCM), relying on natural products, has been playing a very important role in health protection and disease control for thousands of years in Asia, whose therapeutic efficacy is based on the 'synergism', that is, the combinational effects to be greater than that of the individual drug. Based on syndromes and patient characteristics and guided by the theories of TCM, formulae are designed to contain a combination of various kinds of crude drugs that, when combined, generally assume that a synergism of all ingredients will bring about the maximum of therapeutic efficacy. The increasing evidence has shown that multiple active component combinations of TCM could amplify the therapeutic efficacy of each agent, representing a new trend for modern medicine. However, the precise mechanism of synergistic action remains poorly understood. The present review highlights the concept of synergy and gives some examples of synergistic effects of TCM, and provides an overview of the recent and potential developments of advancing drug discovery towards more agile development of targeted combination therapies from TCM.

    Methods for the measurement of therapeutic drugs have covered every aspect of analysis from extraction to derivatization. In general, published methods were modified to shorten drug extractions and overall analysis time. The use of different standards, as well as the frequent omission of internal standards, often produced large and clinically unacceptable analytical variations. As a result, physicians would adjust drug dosages according to the physiological response to a standard dose. The introduction of radioimmunoassay techniques for the quantitation of therapeutic drugs have made a significant impact on the clinical chemistry laboratory. The similarities of the various assay methods and the technologists' familiarity with the assay protocols have produced clinically relevant results. Clinical laboratories are now able to frequently analyze a large number of samples with acceptable accuracy and precision. The esoteric test once performed infrequently is today a routine analytical assay often performed STAT. Therapeutic drug monitoring has become a major activity in many clinical laboratories

    Previous research has shown that the eustachian tube (ET) in animals and humans is lined with a substance that lowers surface tension and thus facilitates the opening of the eustachian tube and aeration of the middle ear. The aims of the present study were to observe the role of eustachian tube surfactant (ETS) on the opening of the ET and to explore the therapeutic effect of natural and artificial ETS on barotitis media (BOM). BOM was successfully established in 50 guinea pigs by simulated ascent in an altitude chamber. Subsets of the affected ears were treated by flushing with natural ETS, artificial ETS, artificial phospholipid, or saline. The effects were evaluated by measuring eustachian tube pressure opening level (POL). Other animals with BOM were treated with artificial ETS on one side and saline in the other, after which the clinical signs were observed. The POL of the saline group remained unchanged. Natural ETS decreased the POL from 11.98 to 6.11 kPa (p congestion in the tympanic membrane was alleviated, the hearing threshold improved, and the effusion in tympanic cavity diminished. Artificial ETS was as effective as natural ETS in facilitating the opening of eustachian tube and had definite therapeutic effects on BOM in this model.

    To determine the long-term effects of therapeutic pulmonary irradiation and treatment with actinomycin D during a period of lung growth, 12 patients treated for Wilms' tumor metastatic to the lung and 8 patients treated for Wilms' tumor with no evidence of pulmonary metastases were studied 7 to 14 years after their initial tumor therapy. All patients had received irradiation to the tumor bed and treatment with actinomycin D. Group 1 had received a single course of bilateral pulmonary irradiation; group 2 had received additional pulmonary irradiation and/or thoracic surgery; group 3 had received no therapeutic irradiation directed primarily to the chest. Total lung capacity (TLC) averaged 71 percent of predicted value in group 1, 58 percent in group 2, and 94 percent in group 3. Diffusing capacity in groups 1 and 2 was reduced to the same extent as lung volume. Quasi-static pressure-volume relationships, studied in three of six patients in group 1, were within the normal range when lung volume was expressed as percentage of observed TLC. Airway resistance, evaluated by spirometry, maximum expiratory flow-volume curves, and resistance of the total respiratory system, was normal or reduced. The data support the hypothesis that therapeutic irradiation during a period of lung growth primarily affects the lung parenchyma and produces a decrease in subsequent size of both the lung and chest wall. No effect of actinomycin D alone upon the lung could be demonstrated

    Full Text Available Peroxisome-proliferator activated receptor-alpha (PPARα is a broadly expressed nuclear hormone receptor and is a transcription factor for diverse target genes possessing a PPAR response element (PPRE in the promoter region. The PPRE is highly conserved, and PPARs thus regulate transcription of an extensive array of target genes involved in energy metabolism, vascular function, oxidative stress, inflammation, and many other biological processes. PPARα has potent protective effects against neuronal cell death and microvascular impairment, which have been attributed in part to its antioxidant and anti-inflammatory properties. Here we discuss PPARα’s effects in neurodegenerative and microvascular diseases and also recent clinical findings that identified therapeutic effects of a PPARα agonist in diabetic microvascular complications.

    Previous research has clearly demonstrated the positive impact of therapeutic interventions on offenders' well-being. Much less is known about the impact on prison staff facilitating and delivering such interventions. We employed qualitative methodology to capture a deeper understanding of the work of therapeutic prison officers. Seven prison officers working in a U.K. Category B therapeutic community prison were interviewed about their working lives, including their own participation in therapy. Following a thematic analysis approach, key findings indicated that the physical and cultural work environment was very important to staff; the therapeutic element of their job role, although demanding, was both satisfying and rewarding; and that working in a therapeutic prison environment provided the opportunity for personal as well as professional development. We conclude that further attention should be given to the unique nature of therapeutic prison work and the positive impact it can have on well-being at work.

    Personal recovery accounts suggest that a positive therapeutic relationship with an optimistic mental health professional may facilitate social inclusion. However, little empirical research has investigated the role of the therapeutic relationship in social outcomes or explored potential mechanisms of change within community psychosis care. This study investigated the direct predictive associations of the therapeutic relationship and professional expectancies for social inclusion and vocational activity for young people with psychosis, and indirect associations through hopefulness. Young people with psychosis and their main mental health professional (n=51 dyads) participated across two time points. Measures of therapeutic relationships, professional expectancies, and vocational activity were obtained at baseline. Measures of hopefulness, social inclusion and vocational activity were obtained at follow-up. Direct and indirect associations between variables were analysed using path modelling. Directed path models were consistent with a positive therapeutic relationship and positive professional expectancies predicting social inclusion and vocational activity through mediation by increased patient domain-specific hopefulness. The professional-rated therapeutic relationship more directly predicts change in vocational activity status. Change in vocational activity status predicts increased patient hopefulness. The therapeutic relationship between professionals and young people with psychosis appears hope-inspiring and important to patients' social inclusion and vocational outcomes. Vocational activity may produce reciprocal gains in hopefulness. Copyright © 2015 Elsevier B.V. All rights reserved.

    2004-01-01

    Background: Serum thyroglobulin assay and 131Iodine (1311) whole body scan are considered complementary in detecting malignant thyroid tissue or metastases. A large number of patients, however, are encountered presenting with scan-negative, thyroglobulin-positive differentiated thyroid carcinoma posing a dilemma in therapeutic management. One of the first alternative scanning agents to be employed is 201Thallium (201Tl). Recent studies have demonstrated its usefulness in identifying lesions that are not visualized with traditional 131I whole body scan. It is not clear, however, whether 201Tl scan helps in the decision-making for subsequent 131I therapy. This study was conducted to determine if 201Tl scan can predict therapeutic 131I uptake and to define the clinical role of 201Tl scanning in these patients. Methods and results: A total of 12 patients (20-63 y/o), 5 males and 7 females, underwent surgery for differentiated thyroid cancer and all had serum thyroglobulin values above 10 ng/ml and normal TPO autoantibodies. Pre-therapy 131I scan using 111 MBq (3mCi) of 131I were obtained. As required for inclusion, all patients had negative pre-therapy scan and negative TPO autoantibody results and underwent 20lTl scanning within 3 weeks. All patients were given 131I therapy (3.7-5.5 GBq or 100-150 mCi) between one to two months after 201Tl scanning. Within a week after therapy, all patients underwent whole body 1311 scanning. 201Tl imaging demonstrated thyroid remnants in 9 out of 12 patients having positive 201Tl scan but negative pre-therapy 1311 scan. However, only 2 of the positive 201Tl scans showed 131I uptake post-therapy (positive predictive value of 20%). None of the subjects presented with a negative 201Tl scan and a positive post-therapy 131I scan. Conclusion: Our study suggests that evidence of remnants or metastases on 201Tl scanning may be an inappropriate basis for the decision to proceed with 131I therapy. The role of 20lTl imaging in this subset of

    The radioprotective effect of indralin in rhesus monkeys was examined over 60 d following gamma irradiation. Male and female rhesus macaques (Macaca mulatta) 2-3-years-old and weighing 2.1-3.5 kg were used. Animals were exposed to total-body gamma irradiation from 60 Co at a dose of 6.8 Gy (lethal dose, 100% lethality over 30 days). Indralin (40-120 mg kg -1 ) was administered intramuscularly 5 min prior to radiation exposure. Indralin taken at a dose of 120 mg kg -1 protected five out of six monkeys (compared with the radiation control group, in which all 10 animals died). The average effective dose of indralin in the monkeys exposed to gamma irradiation for 30 min was equal to 77.3 (63.3-94.3) mg kg -1 , and the maximum tolerated dose of indralin administered to monkeys was 800 mg kg -1 . Indralin reduced radiation-induced injuries in macaques, thus resulting in a less severe course of acute radiation syndrome. Delayed and less pronounced manifestation of the haemorrhagic syndrome of the disease, and milder forms of both leukopenia and anaemia were also noted. The therapeutic index for indralin, expressed as the ratio of the maximum tolerated dose to the average effective dose, was equal to 10. Therefore, indralin has a significant radioprotective effect against radiation and has a high therapeutic index in rhesus monkeys. (author)

    Hyperthyroidism is a hypermetabolic syndrome characterized by an overproduction of thyroid hormones, which enhances the hormone-induced oxidative stress responsible for some complications in the liver, heart and muscle. Blue honeysuckle (BH) is an edible berry, rich in polyphenols, especially flavonoids or anthocyanins, known as strong antioxidants. The chemo-protective activities of the berry have been connected to the improvement of symptoms in cancer, diabetes mellitus, tumor or cardiovascular diseases. Therefore, the therapeutic effects of BH were examined in hyperthyroidism rat model. The hyperthyroidism was induced by injection with levothyroxine (LT4), and the model was treated with distilled water (LT4 control), propylthiouracil (PTU) or BH at 3 dosages of 500, 250 and 125[Formula: see text]mg/kg. The treatment was performed once a day for 15 days. Compared to LT4 control, the oral administration of BH dose-dependently ameliorated the hyperthyroidism, reducing thyroid hormones and increasing thyroid stimulating hormones. These effects were accompanied by improvement of body weight loss and atrophy in the thyroid gland, liver and epididymal fat pads. BH treatments also reduced the levels of hepatic enzymes (AST and ALT), which suggests BH exerts protective effects on hepatocytes. BH might also be involved in the augmentation of the anti-oxidant activities, supported by increased endogenous antioxidant (glutathione). In addition, the histopathological analyses revealed the beneficial effects of BH on the atrophic changes and cellular injuries in the thyroid gland, liver and epididymal fat pads. The therapeutic potentials of BH were either similar or more effective than PTU. These results provide valuable information that will guide more detailed studies to use the BH as a complementary and alternative medicine.

    Between 75-90% of nursing home (NH) residents with dementia develop behavioral symptoms (BSD) which may be associated with a stress response. Therapeutic touch has been shown to decrease restlessness in NH residents, however the mechanism is unknown. The purpose of this randomized controlled trial (RCT) was to examine the effect of therapeutic touch on BSD and basal cortisol levels among NH residents with dementia. Using a double blind experimental interrupted time series ABAB design, 65 participants were assigned to one of three groups. The experimental group received therapeutic touch with contact on the neck and shoulders delivered twice daily for 3 days (administered over 2 separate treatment periods); the placebo group received a mimic treatment identical in appearance, and the control group received routine care. Study outcomes were BSD, measured by the modified Agitated Behavior Rating Scale (mABRS), and salivary cortisol levels, measured by enzyme-linked immunosorbent assay (ELISA). 64 residents, aged 67-93 years (M = 85.5, SD = 5.50), completed the study. Restlessness was significantly reduced in the experimental group compared to the control group (p = 0.03). There was a significant difference in morning cortisol variability among groups across time periods (touch may be effective for management of symptoms like restlessness coupled with stress reduction. At a time when cost containment is a consideration in health care, therapeutic touch is an intervention that is non-invasive, readily learned, and can provide a non-pharmacologic alternative for selected persons with BSD.

    Therapeutic cannabis administration is increasingly used in Western countries due to its positive role in several pathologies. Dronabinol or tetrahydrocannabinol (THC) pills, ethanolic cannabis tinctures, oromucosal sprays or table vaporizing devices are available but other cannabinoids forms can be used. Inspired by the illegal practice of dabbing of butane hashish oil (BHO), cannabinoids from cannabis were extracted with butane gas, and the resulting concentrate (BHO) was atomized with specific vaporizing devices. The efficiency of "cannavaping," defined as the "vaping" of liquid refills for e-cigarettes enriched with cannabinoids, including BHO, was studied as an alternative route of administration for therapeutic cannabinoids. The results showed that illegal cannavaping would be subjected to marginal development due to the poor solubility of BHO in commercial liquid refills (especially those with high glycerin content). This prevents the manufacture of liquid refills with high BHO concentrations adopted by most recreational users of cannabis to feel the psychoactive effects more rapidly and extensively. Conversely, "therapeutic cannavaping" could be an efficient route for cannabinoids administration because less concentrated cannabinoids-enriched liquid refills are required. However, the electronic device marketed for therapeutic cannavaping should be carefully designed to minimize potential overheating and contaminant generation.

    Full Text Available Objective To screen and select new drugs for aplastic anemia (AA and evaluate their clinical efficacy by clinical bioinformatics methods. Methods First, we established genome expression profiles of AA patients, and conducted similarity analyses with the pharmacogenomics database to screen and select drugs with possible efficacy. Intractable AA patients who received immunosuppressors and/or androgen for more than six months showing no clinical efficacy were enrolled in the study to evaluate therapeutic effects of the therapeutic regime. Clinical efficacy and adverse effects were evaluated after six months. Results The clinical bioinformatics results showed therapeutic effects of metformin hydrochloride on AA. Forty-three intractable AA patients (15 with severe AA were treated with metformin hydrochloride combined with cyclosporin A (CsA and stanozolol. Twenty-seven transfusion-dependent patients (100% became transfusion independent after a 6-month therapy. The hemoglobin level completely returned to normal in 37 out of 40 anemia patients (92.5%. In the 40 patients with platelet count lower than 20×109/L, the platelet count of 28 patients (90.3% increased to higher than 50×109/L. The white cell count increased to higher than 3.5×109/L in 30 out of 35 patients (88.6% with white cell count lower than 2.5×109/L. Among 40 anemic patients, 1 was found to have abnormal renal function, but it recovered to the normal range after ending CsA treatment. Eighteen patients were found to have elevated transaminase levels which were lowered to normal range after using liver protectants and reducing the dosage of stanozolol. There were no instances of hypoglycemia in all patients throughout the treatment. Conclusion Combination of metformin hydrochloride, CsA and stanozolol is effective in refractory aplastic anemia with acceptable toxicity.

    Atrial fibrillation (AF) and heart failure (HF) frequently coexist. We have previously demonstrated that selective atrioventricular node (AVN) vagal stimulation (AVN-VS) can be used to control ventricular rate during AF. Due to withdrawal of vagal activity in HF, the therapeutic effects of AVN-VS may be compromised in the combined condition of AF and HF. Accordingly, this study was designed to evaluate the therapeutic effects of AVN-VS to control ventricular rate in AF and HF. A combined model of AF and HF was created by implanting a dual chamber pacemaker in 24 dogs. A newly designed bipolar electrode was inserted into the ganglionic AVN fat pad and connected to a nerve stimulator for delivering AVN-VS. In all dogs, HF was induced by high rate ventricular pacing at 220 bpm for 4 weeks. AF was then induced and maintained by rapid atrial pacing at 600 bpm after discontinuation of ventricular pacing. These HF + AF dogs were randomized into control (n = 9) and AVN-VS (n = 15) groups. In the latter group, vagal stimulation (310 μs, 20 Hz, 3-7 mA) was delivered continuously for 6 months. Compared with the control, AVN-VS had a consistent effect on ventricular rate slowing (by >50 bpm, all P AVN-VS was well tolerated by the treated animals. AVN-VS achieved consistent rate slowing, which was associated with improved ventricular function in a canine AF and HF model. Thus, AVN-VS may be a novel, effective therapeutic option in the combined condition of AF and HF. © 2012 Wiley Periodicals, Inc.

    To observe the effect of surfactant on eustachian tube (ET) on the opening of ET as well as it's therapeutic role in barotitis media (BM). 50 guinea pigs were successfully established as BM models by stimulated ascending in altitude chamber. Parts of the models were treated with by middle ear flushing with nature ETS, artificial ETS, artificial phospholipid and saline, after which the eustachian tube pressure opening level (POL) of each group was tested. Others were injected with 1 ml artificial ETS in on side of the middle ear, and 1 ml of saline in the other served as control. Natural ETS decreased the POL from 11.98 to 6.11 kPa (P congestion in drum membrane alleviated, the hearing threshold of ETS group improved and the effusion in tympanic cavity lessened. The results suggest that artificial ETS is as effective as nature ETS to facilitates the opening of eustachian tube. Artificial ETS may exert therapeutic effects on BM.

    The present work was oriented to investigate the effectiveness of Prussian blue (PB), vermiculite and diethylenetriaminepentaacetic acid (CaDTPA) as therapeutic agents for the elimination of either 134 Cs or 60 Co from contaminated rats after intake of one of the isotopes. The study was performed by using 48 adult rats divided into 8 identical groups each of six rats having approximately the same body weight. The groups included a reference group, without isotope or therapeutic agent administration, four groups given one of the isotopes and four groups given the isotopes and treated with different therapeutic regimes. The isotope content of the treated and untreated contaminated rats were followed by daily whole body radiometric counting for three weeks. On plotting log % radionuclide retained as a function of time, elapsed between radionuclide administration and radiometric counting, straight lines were obtained. The results indicate that excretion can mostly be represented by two stages; the first is fast followed by a second slow stage. The % radionuclide excreted, the corresponding rate constant and the biological half-life of each stage was estimated. It was found that the application of PB + vermiculite is more efficient, to remove 134 Cs, from contaminated rats, than PB only and CaDTPA is more efficient to remove 60Co. Therefore, it is recommended to use the three therapeutic agents to remove both isotopes when taken simultaneously

    It has been reported that suppression of protein kinase N3 (PKN3) expression in vascular and lymphatic endothelial cells results in the inhibition of tumor progression and lymph node metastasis formation. The present study investigated whether combination therapy of small interfering RNA (siRNA) against PKN3 and doxorubicin (DXR) could increase therapeutic efficacy against liver and lung metastases. In vitro transfection of PKN3 siRNA into PKN3-positive MDA-MB-231, LLC, and Colon 26 cells and PKN3-negative MCF-7 cells did not inhibit cell growth and did not increase sensitivity to DXR. However, following in vivo treatment, PKN3 siRNA suppressed the growth of liver MDA-MB-231 and lung LLC and MCF-7 metastases, although combination therapy with DXR did not increase the therapeutic efficacy. By contrast, in liver MCF-7 metastases, PKN3 siRNA or DXR alone did not exhibit significant inhibition of tumor growth, but their combination significantly improved therapeutic efficacy. Treatment of liver MDA-MB-231 metastases with PKN3 siRNA induced a change in vasculature structure via suppression of PKN3 mRNA expression. PKN3 siRNA may induce antitumor effects in lung and liver metastases by suppression of PKN3 expression in stroma cells, such as endothelial cells. From these findings, PKN3 siRNA alone or in combination with DXR may reduce the tumor growth of liver and lung metastases regardless of PKN3 expression in tumor cells. PMID:29098022

    Client engagement in substance misuse treatment programs is directly associated with positive treatment outcomes. The nature of these programs means there are often difficulties engaging and retaining clients, but authors have consistently found a strong therapeutic alliance is associated with client engagement. While research has focused on the association between the alliance and engagement, the factors that influence the therapeutic alliance have received less attention. To examine therapists' characteristics, namely therapists' stress and empathy levels, as potential predictors of client engagement and the therapeutic alliance, within an adolescent substance misuse group treatment program. The sample included 84 adolescent clients and 14 therapists from a Secure Training Centre in England. Client engagement in the treatment program was observed, while self-reporting measures assessed the therapeutic alliance (client and therapist-rated), and therapists' stress and empathy levels. Multiple regression analysis revealed that therapists' stress levels negatively influenced the therapeutic alliance and had a curvilinear relationship with client engagement, indicating that stress is not exclusively negatively related to engagement. Although stress was found to negatively impact both cognitive and affective empathy, neither cognitive nor affective empathy were significantly related to client engagement or the therapeutic alliance. This study demonstrates the importance of therapist characteristics on client engagement and the therapeutic alliance. Within practice stress can have a positive impact on clients' engagement. Nevertheless, therapists may need additional support to deal with stress effectively. Therapists' empathy may too be fundamental to client engagement, but only it if is perceived by clients.

    To evaluate the therapeutic effects of probiotics on neonatal jaundice and the safety. Sixty-eight neonates with jaundice were divided into a control group and a treatment group (n=34) randomly, and treated by blue light phototherapy and that in combination with probiotics. The serum bilirubin levels were detected before and 1, 4, 7 days after treatment. The time when therapy showed effects and jaundice faded, clinical outcomes as well as adverse reactions were recorded. The categorical data were expressed as (±s) and compared by t test. The numerical data were expressed as (case, %) and compared by χ² test. P0.05). The levels significantly decreased 1, 4 and 7 days after treatment (P0.05). The treatment group underwent more significant decreases on the 4th and 7th days than the control group did (P=0.002, 0.001). In the treatment group, the therapy exerted effects on (1.0±0.5) d and jaundice faded on (3.8±1.7) d, which were (2.6±0.6) d and (5.3±2.1) d respectively in the control group (P=0.001, 0.002). The effective rate of the treatment group significantly exceeded that of the control group (P=0.002). There were no obvious adverse reactions in either group. Probiotics lowered the serum bilirubin levels of neonates with jaundice rapidly, safely and significantly, and accelerated jaundice fading as well. This method is worthy of application in clinical practice.

    Full Text Available The positivity effect refers to an age-related trend that favors positive over negative stimuli in cognitive processing. Relative to their younger counterparts, older people attend to and remember more positive than negative information. Since the effect was initially identified and the conceptual basis articulated (Mather & Carstensen, 2005 scores of independent replications and related findings have appeared in the literature. Over the same period, a number of investigations have failed to observe age differences in the cognitive processing of emotional material. When findings are considered in theoretical context, a reliable pattern of evidence emerges that helps to refine conceptual tenets. In this article we articulate the operational definition and theoretical foundations of the positivity effect and review the empirical evidence based on studies of visual attention, memory, decision-making, and neural activation. We conclude with a discussion of future research directions with emphasis on the conditions where a focus on positive information may benefit and/or impair cognitive performance in older people.

    Full Text Available Cannabis is one of the oldest psychotropic drugs known to humanity. The paper assesses the current knowledge on the cannabis, including the mechanisms of action and the therapeutic potential of cannabinoids. Three varieties of Cannabis plant are recognised: Cannabis sativa, Cannabis indica, and Cannabis ruderalis. The variety indica is used predominantly to obtain the drugs. Cannabis herb is usually named marijuana, while the cannabis oleoresin secreted by the glandular hairs found mainly on the flowering or fruiting tops of the plant is known as hashish. More than 400 known chemicals are present in cannabis, at least 70 of which are called cannabinoids. The major psychoactive constituent in cannabis is delta-9-tetrahydrocannabinol (Δ9-THC. It is now recognized that there are three types of cannabinoids: natural (phytocannabinoids, endogenous cannabinoids, and synthetic cannabioids. Cannabinoids exert their actions by binding to specific membrane protein, the cannabinoid receptor. To date, two subtypes of cannabinoid receptors, named cannabinoid-1 (CB1, most abundantly expressed in the central nervous system and cannabinoid-2 (CB2 receptors, found predominantly in peripheral tissues with immune functions have been cloned. Therefore, the concept of endogenous cannabinoid system (endocannabinoid system, SEC has been developed. Based on the current scientific evidence, there are several effects of cannabinoids with potential therapeutic use: antiemetic, analgesic in cancerous pains, and chronic neuropathic pain, in multiple sclerosis or spinal cord injuries. Cannabis consume can result in a state of drug dependency and cannabis withdrawal has been included in DSM-V. Cannabis plant remains controversial in the twenty-first century and the potential therapeutic of specific cannabinoid compounds and medical marijuana remains under active medical research.

    Infrared radiation has a potential therapeutic effect in some diseases. The aim of this study was to estimate the therapeutic role of near infrared heat lamp (NIRHL) on the variations of the activity of paraoxonase 1 (PON1) and myeloperoxidase (MPO), in relation to lipid disorders, associated with oxidative stress in rats gamma-irradiated. In addition, study the effect of the duration of NIRHL treatment. Animals were divided into six groups. The results revealed that irradiated rats treated with NIRHL 20 min/once/day showed positive modulation of PON1 and MPO linked to significant improvement of lipid disorders evidenced by lower triglycerides, low density lipoprotein cholesterol (LDL-C), oxidized low density lipoprotein cholesterol (oxLDL-C) and higher density lipoprotein cholesterol (HDL-C) as well as significant amelioration of redox state, manifested by markedly increase of glutathione (GSH) content, total antioxidant capacity (TAC) associated with a noticeable decrease of pro-inflammatory cytokines. (TNF-α, IL-1 beta and IL-6), nitric oxide (NO), nitric oxide synthase (NOs), malondialdehyde (MDA), compared to irradiated rats. The results showed also that the NIRHL treatment for 20 min/twice/day had negative effects on the previous parameters and on the behavior of rats such as itching, irritability, dyspnea and death in normal as well as, irradiated rats. In conclusion, the results in this study show that NIRHL therapy for a short time can effectively prevent the lipid disorders induced by radiation through the positive modulation mechanism of PON1 and MPO enzymes and improvement of oxidative stress.

    Duchenne muscular dystrophy (DMD) is a lethal, degenerative muscle disease with no effective treatment. DMD muscle pathogenesis is characterized by chronic inflammation, oxidative stress, and fibrosis. Statins, cholesterol-lowering drugs, inhibit these deleterious processes in ischemic diseases affecting skeletal muscle, and therefore have potential to improve DMD. However, statins have not been considered for DMD, or other muscular dystrophies, principally because skeletal-muscle-related symptoms are rare, but widely publicized, side effects of these drugs. Here we show positive effects of statins in dystrophic skeletal muscle. Simvastatin dramatically reduced damage and enhanced muscle function in dystrophic (mdx) mice. Long-term simvastatin treatment vastly improved overall muscle health in mdx mice, reducing plasma creatine kinase activity, an established measure of muscle damage, to near-normal levels. This reduction was accompanied by reduced inflammation, more oxidative muscle fibers, and improved strength of the weak diaphragm muscle. Shorter-term treatment protected against muscle fatigue and increased mdx hindlimb muscle force by 40%, a value comparable to current dystrophin gene-based therapies. Increased force correlated with reduced NADPH Oxidase 2 protein expression, the major source of oxidative stress in dystrophic muscle. Finally, in old mdx mice with severe muscle degeneration, simvastatin enhanced diaphragm force and halved fibrosis, a major cause of functional decline in DMD. These improvements were accompanied by autophagy activation, a recent therapeutic target for DMD, and less oxidative stress. Together, our findings highlight that simvastatin substantially improves the overall health and function of dystrophic skeletal muscles and may provide an unexpected, novel therapy for DMD and related neuromuscular diseases.

    The functional integration of external and internal signals forms the basis of information processing and is essential for higher cognitive functions. This occurs in finely tuned cortical microcircuits whose functions are balanced at the cellular level by excitatory glutamatergic pyramidal neurons and inhibitory gamma-aminobutyric acidergic (GABAergic) interneurons. The balance of excitation and inhibition, from cellular processes to neural network activity, is characteristically disrupted in multiple neuropsychiatric disorders, including major depressive disorder (MDD), bipolar disorder, anxiety disorders, and schizophrenia. Specifically, nearly 3 decades of research demonstrate a role for reduced inhibitory GABA level and function across disorders. In MDD, recent evidence from human postmortem and animal studies suggests a selective vulnerability of GABAergic interneurons that coexpress the neuropeptide somatostatin (SST). Advances in cell type-specific molecular genetics have now helped to elucidate several important roles for SST interneurons in cortical processing (regulation of pyramidal cell excitatory input) and behavioral control (mood and cognition). Here, we review evidence for altered inhibitory function arising from GABAergic deficits across disorders and specifically in MDD. We then focus on properties of the cortical microcircuit, where SST-positive GABAergic interneuron deficits may disrupt functioning in several ways. Finally, we discuss the putative origins of SST cell deficits, as informed by recent research, and implications for therapeutic approaches. We conclude that deficits in SST interneurons represent a contributing cellular pathology and therefore a promising target for normalizing altered inhibitory function in MDD and other disorders with reduced SST cell and GABA functions.

    Background: Genomic data from human epidermal growth factor receptor 2–positive (HER2+) tumors were analyzed to assess the association between intrinsic subtype and clinical outcome in a large, well-annotated patient cohort. Methods: Samples from the NCCTG (Alliance) N9831 trial were analyzed using the Prosigna algorithm on the NanoString platform to define intrinsic subtype, risk of recurrence scores, and risk categories for 1392 HER2+ tumors. Subtypes were evaluated for recurrence-free survival (RFS) using Kaplan-Meier and Cox model analysis following adjuvant chemotherapy (n = 484) or chemotherapy plus trastuzumab (n = 908). All statistical tests were two-sided. Results: Patients with HER2+ tumors from N9831 were primarily scored as HER2-enriched (72.1%). These individuals received statistically significant benefit from trastuzumab (hazard ratio [HR] = 0.68, 95% confidence interval [CI] = 0.52 to 0.89, P = .005), as did the patients (291 of 1392) with luminal-type tumors (HR = 0.52, 95% CI = 0.32 to 0.85, P = .01). Patients with basal-like tumors (97 of 1392) did not have statistically significantly better RFS when treated with trastuzumab and chemotherapy compared with chemotherapy alone (HR = 1.06, 95% CI = 0.53 to 2.13, P = .87). Conclusions: The majority of clinically defined HER2-positive tumors were classified as HER2-enriched or luminal using the Prosigna algorithm. Intrinsic subtype alone cannot replace conventional histopathological evaluation of HER2 status because many tumors that are classified as luminal A or luminal B will benefit from adjuvant trastuzumab if that subtype is accompanied by HER2 overexpression. However, among tumors that overexpress HER2, we speculate that assessment of intrinsic subtype may influence treatment, particularly with respect to evaluating alternative therapeutic approaches for that subset of HER2-positive tumors of the basal-like subtype.

    2011-08-01

    This research review and meta-analysis presents an overview of the effects of hippotherapy and therapeutic horseback riding (THR) on postural control or balance in children with cerebral palsy (CP). To synthesize previous research findings, a systematic review and meta-analysis were undertaken. Relevant studies were identified by systematic searches of multiple online databases from the inception of the database through to May 2010. Studies were included if they fulfilled the following criteria: (1) quantitative study design, (2) investigation of the effect of hippotherapy or THR on postural control or balance, and (3) the study group comprised children and adults with CP. The selected articles were rated for methodological quality. The treatment effect was coded as a dichotomous outcome (positive effect or no effect) and quantified by odds ratio (OR). The pooled treatment effect was calculated using a random-effects model. Meta-regression of the effect size was performed against study covariates, including study size, publication date, and methodological quality score. From 77 identified studies, 10 met the inclusion criteria. Two were excluded because they did not include a comparison group. Therapy was found to be effective in 76 out of 84 children with CP included in the intervention groups. The comparison groups comprised 89 children: 50 non-disabled and 39 with CP. A positive effect was shown in 21 of the children with CP in the comparison group regardless of the activity undertaken (i.e. physiotherapy, occupational therapy, sitting on a barrel or in an artificial saddle). The pooled effect size estimate was positive (OR 25.41, 95% CI 4.35, 148.53), demonstrating a statistically significant effectiveness of hippotherapy or THR in children with CP (phippotherapy and THR. Although the generalization of our findings may be restricted by the relatively small sample size, the results clearly demonstrate that riding therapy is indicated to improve postural control

    Whether the therapeutic nasal continuous positive airway pressure (CPAP) derived from manual titration is the same as derived from automatic titration is controversial. The purpose of this study was to compare the therapeutic pressure derived from manual titration with automatic titration. Fifty-one patients with obstructive sleep apnoea (OSA) (mean apnoea/hypopnoea index (AHI) = 50.6 ± 18.6 events/h) who were newly diagnosed after an overnight full polysomnography and who were willing to accept CPAP as a long-term treatment were recruited for the study. Manual titration during full polysomnography monitoring and unattended automatic titration with an automatic CPAP device (REMstar Auto) were performed. A separate cohort study of one hundred patients with OSA (AHI = 54.3 ± 18.9 events/h) was also performed by observing the efficacy of CPAP derived from manual titration. The treatment pressure derived from automatic titration (9.8 ± 2.2 cmH(2)O) was significantly higher than that derived from manual titration (7.3 ± 1.5 cmH(2)O; P titration (54.3 ± 18.9 events/h before treatment and 3.3 ± 1.7 events/h after treatment; P titration pressure derived from REMstar Auto is usually higher than the pressure derived from manual titration. © 2013 The Authors.

    This study tested whether time perspective, a central tenant of socioemotional selectivity theory (Carstensen, 2006), moderates positivity effects in emotional memory. To provide measures of time perspective, young (YA; M = 22.48 years), young-old (YO; M = 67.56 years), old-old adults (OO; M = 80.24 years), and participants with moderate severity Alzheimer's disease (PAD; M = 84.28 years) completed a line task and reported subjective age. As expected, YA, YO, and OO reported successively more constrained future time perspectives. PAD showed distortion in time perspective, envisioning a future comparable with the YO, although closer matched in chronological age to OO adults. To evince positivity effects, participants were oriented to pairs of emotional images and were then tested for memory (recall and recognition) of the images. Recall and recognition memory for the images indicated an age-related advantage for positive over negative material (positivity effects). Time perspective, however, did not moderate these age effects. In memory performance, PAD were more comparable with OO adults with whom they shared a similar chronological age, rather than YO adults, who had a corresponding time perspective. These results suggest that age correlates that are shared by PAD and OO, such as reduced processing resources, rather than time perspective, may drive the age associated positivity effects.

    Stroke is a result of cerebral ischemia that triggers a cascade of both physiological and biochemical events. No effective treatment is available for stroke; however, stem cells have the potential to rescue tissue from the effects of stroke. Adipose-derived stem cells (ADSCs) are an abundant source of adult stem cells; therefore, ADSC therapy can be considered as a future strategy for regenerative medicine. However, more research is required to improve the effectiveness of transplanted ADSCs as a treatment for stroke in the mouse stroke model. Ligustilide, isolated from the herb Angelica sinensis, exhibits a protective effect on neurons and inhibits inflammation. We also demonstrated that ligustilide treatment increases the expression levels of homing factors such as SDF-1 and CXCR4. In the present study, we evaluated the therapeutic effects of ADSC transplantation and ligustilide treatment in a mouse thromboembolic stroke model by behavioral tests, including beam walking, locomotor activity, and rotarod analysis. ADSCs pretreated with ligustilide were transplanted into the brains of stroke mice. The results showed that the therapeutic effect of ADSCs pretreated with ligustilide was better than that of ADSCs without ligustilide pretreatment. There was no difference between the recovery of mice treated by ADSC transplantation combined with subcutaneous ligustilide injection and that of mice treated only with ADSCs. The TUNEL assay showed fewer apoptotic cells in the brains of mice transplanted with ADSCs pretreated with ligustilide as well as in those without pretreatment. In summary, pretreatment of ADSCs with ligustilide improves the therapeutic efficacy of ADSC transplantation. The results of this study will help improve stem cell therapies being developed for future clinical applications.

    Prevention of COPD requires appropriate patient education, especially of adolescents, as well as the establishment of an effective national health policy. The new GOLD guidelines represent the current standard of knowledge on the management of chronic, progressive, obstructive pulmonary diseases. It points out that COPD is avoidable and treatable,and hence, there is no reason for therapeutic nihilism. Chronic bronchitis preceding a progressive respiratory obstruction cannot be improved with the presently available respiratory therapeutics. For this reason, therapeutic measures concentrate on the avoidance of exacerbations, which are primarily responsible for the severity of the course of COPD.

    The Marketing Authorization (MA) granted to a new molecular entity does not allow for proper anticipation of its future positioning within the therapeutic strategy. A specific methodology should be devised as early as during the pre-MA development phase that could result in an initial positioning that should be subjected to further reappraisal with regard to scientific advances, the arrival of new treatments and further developments with this molecule. A methodology is thus proposed, based on early optimisation of the development plan, the granting of subsequent MAs, and reappraisal of the positioning within the strategy, based on analysis of all available data. It should be possible to take into account the economic context, within an agreed system with pre-defined medico-economic criteria. This may in turn raise the issue of the role of the various parties involved in this assessment, as well as how to understand the respective opinions of stakeholders: authorities, sponsors, prescribers and patients, each of whom has a specific view of the definition of the strategic objective that should apply to the disease concerned.

  7. Therapeutic Vaccination for HPV Induced Cervical Cancers

    2007-01-01

    Full Text Available Cervical Cancer is the second leading cause of cancer–related deaths in women worldwide and is associated with Human Papillomavirus (HPV infection, creating a unique opportunity to treat cervical cancer through anti-viral vaccination. Although a prophylactic vaccine may be available within a year, millions of women, already infected, will continue to suffer from HPV-related disease, emphasizing the need to develop therapeutic vaccination strategies. A majority of clinical trials examining therapeutic vaccination have shown limited efficacy due to examining patients with more advanced-stage cancer who tend to have decreased immune function. Current trends in clinical trials with therapeutic agents examine patients with pre-invasive lesions in order to prevent invasive cervical cancer. However, longer follow-up is necessary to correlate immune responses to lesion regression. Meanwhile, preclinical studies in this field include further exploration of peptide or protein vaccination, and the delivery of HPV antigens in DNA-based vaccines or in viral vectors. As long as pre-clinical studies continue to advance, the prospect of therapeutic vaccination to treat existing lesions seem good in the near future. Positive consequences of therapeutic vaccination would include less disfiguring treatment options and fewer instances of recurrent or progressive lesions leading to a reduction in cervical cancer incidence.

    This study explored the effects on bulimic symptomatology of a writing task intended to reduce emotional avoidance. Eighty individuals reporting symptoms of bulimia completed, by e-mail, a therapeutic or control writing task. Participants completed questionnaires on bulimic symptoms, mood, and potential moderating and mediating factors, and were followed up after 4 and 8 weeks. Writing content was explored using a word count package and qualitative framework analysis. Bulimic symptoms decreased in both groups, although in both groups the number of participants who improved was approximately equal to the number who did not improve. Symptom decreases were associated with increases in perceived mood regulation abilities, and decreases in negative beliefs about emotions. Participants preferred internet delivery to face to face discussion. For individuals experiencing symptoms of bulimia, the effects of therapeutic writing did not differ significantly from effects of a control writing task. 2009 by Wiley Periodicals, Inc.

    Inpatient psychotherapy includes the patient's manifold contacts with different therapists, nurses and fellow patients. The present study investigated the association between these multiple relationships and therapy outcome. Pre-post measures of symptom load (Brief Symptom Inventory), interpersonal problems (IIP) and self-efficacy (SEB) were used to define three groups with positive (N=129), unchanged (N=44) or negative (N=40) outcome. These groups were compared 1) by their alliance with an individual therapist, their relationship to the therapeutic team, their experience of cohesion and climate concerning fellow patients in the ward (measured weekly by the "Stationserfahrungsbogen" SEB), and 2) by their differences in mean correlations between the courses of relationship experiences and symptom load. Cohesion and relationship to the therapeutic team were not associated with therapy outcome. Therapeutic alliance with the individual therapist and climate among fellow patients turned out to be moderate indicators of the therapeutic outcome. It is recommended to include these process parameters systematically into the process diagnostics of inpatient psychotherapy.

    Full Text Available Following optic nerve injury associated with acute or progressive diseases, retinal ganglion cells (RGCs of adult mammals degenerate and undergo apoptosis. These diseases have limited therapeutic options, due to the low inherent capacity of RGCs to regenerate and due to the inhibitory milieu of the central nervous system. Among the numerous treatment approaches investigated to stimulate neuronal survival and axonal extension, cell transplantation emerges as a promising option. This review focuses on cell therapies with bone marrow mononuclear cells and bone marrow-derived mesenchymal stem cells, which have shown positive therapeutic effects in animal models of optic neuropathies. Different aspects of available preclinical studies are analyzed, including cell distribution, potential doses, routes of administration, and mechanisms of action. Finally, published and ongoing clinical trials are summarized.

    Full Text Available Teresa Conner-Kerr,1 Mary Ellen Oesterle2 1College of Health Sciences & Professions, 2Department of Physical Therapy, University of North Georgia, Dahlonega, GA, USA Abstract: Although therapeutic ultrasound has been in existence since the 1930s, questions remain as to its effectiveness in promoting tissue healing in various injured tissues. These tissues include soft tissues such as skin, tendons, ligaments, bursae, joint capsules and muscles. Limited evidence exists to support a role for therapeutic ultrasound in closed, soft tissue lesions. However, an evolving literature provides support for the role of therapeutic ultrasound in the treatment of chronic wounds, acute injuries such as fractures and split thickness graft donor sites as well as in the modulation of wound-related pain. Modern technology that uses low-frequency (kilohertz, long wave ultrasound appears promising compared to older, higher frequency ultrasound (megahertz devices. These newer devices appear to have positive effects on healing rates in various wound types, pain levels and the modulation of proinflammatory cytokines.

    Full Text Available Residues from herbal medicine processing in pharmaceutical plants create a large amount of waste (herb residues, which consists mainly of environmental pollution and medicinal waste. In order to resolve this problem, probiotics of Bacillus (B. subtilis, Aspergillus (A. oryzae, and Lactobacillus (L. plantarum M3 are selected to reuse herb residue of Jianweixiaoshi tablets (JT, and an antibiotic-associated diarrhea (AAD mouse model was established to evaluate the therapeutic effects of the herb residue fermentation supernatant. Our results indicated that the fermentation supernatant had scavenged 77.8% of 2,2-diphenyl-1-picrylhydrazyl (DPPH, 78% of O2•−, 36.7% of •OH, 39% of Fe2+ chelation, and 716 mg/L reducing power. The inhibition zones for Salmonella (S. typhimurium, S. enteritidis, Shigella (Sh. flexneri, Escherichia (E. coli, Listeria (L. monocytogenes, Sh. dysenteriae 301, and Staphylococcus (S. aureus were 17, 14, 19, 18, 20, 19, and 20 mm, respectively. The in vivo results indicated that the fermentation supernatant resulted in a high diarrhea inhibition rate (56%, p<0.05, greatly enhanced the disruption of bacterial diversity caused by antibiotics, and restored the dominant position of L. johnsonii in the treatment and recovery stages. Therefore, the combination of the herb residue and probiotics suggests a potential to explore conversion of these materials for the possible development of therapies for AAD.

  13. Epigenetic targeting in acute myeloid leukemia: use of flow cytometry in monitoring therapeutic effects.

    2007-12-01

    Flow cytometric techniques have emerged as a powerful tool in hematology allowing fast, sensitive and reproducible multi-parametric analyses at the single cell level of heterogeneous samples. Small subsets of cells can be studied with high degree of accuracy, and a broad and constantly increasing specter of antibodies is available. Flow cytometry has therefore become the method of choice for evaluation of therapeutic effects at single cell level. These methodological approaches can easily be used to study hematological malignancies, and the future use of this strategy in other malignancies will depend on the development of laboratory techniques to prepare suspensions of viable cells also from tumor biopsies. The selection of biological parameters for evaluation of treatment effects should probably be based on (i) molecular markers involved in cancer-associated genetic abnormalities; (ii) other molecular markers showing altered expression in the malignant cells and thought to be involved in leukemogenesis or having a prognostic impact; (ii) functional assays known to reflect biological characteristics that are important in carcinogenesis (e.g. cell cycle distribution, functional evaluation of apoptosis regulation). These molecules will in addition often represent the therapeutic targets when new anticancer drugs are developed. In this review we use treatment of acute myeloid leukemia with histone deacetylase inhibitors as an example. Based on the criteria mentioned above we suggest that the monitoring of therapeutic effects on the cancer cells in these patients should include differentiation status, histone acetylation, cell cycle distribution, pro- and anti-apoptotic signaling balance and intracellular levels of various transcription factors.

    Equine assisted activities (hippotherapy and therapeutic riding) improve balance in patients with disabilities such as cerebral palsy, but have not been systematically studied in older adults, at risk of falls due to balance deficits. We conducted a 10-week, single blind, controlled trial of the effect of a therapeutic horseback riding course on measures of balance in community-dwelling adults 65 years and older. Nine riders and six controls completed the trial. Controls were age matched to riders and all participants were recruited from the local community. Both groups showed improvements in balance during the trial, but did not reach statistical significance. Sample size was small, participants had relatively high initial balance scores, and controls tended to increase their physical activities, likely influencing outcomes. No adverse events occurred and the supervised therapeutic riding program appeared to be a safe and effective form of exercise to improve balance in older adults. A power analysis was performed to estimate numbers of participants needed for a larger study. © The Author(s) 2012.

    We assessed evidence for a contextual effect of positive intergroup contact, whereby the effect of intergroup contact between social contexts (the between-level effect) on outgroup prejudice is greater than the effect of individual-level contact within contexts (the within-level effect). Across seven large-scale surveys (five cross-sectional and two longitudinal), using multilevel analyses, we found a reliable contextual effect. This effect was found in multiple countries, operationalizing context at multiple levels (regions, districts, and neighborhoods), and with and without controlling for a range of demographic and context variables. In four studies (three cross-sectional and one longitudinal) we showed that the association between context-level contact and prejudice was largely mediated by more tolerant norms. In social contexts where positive contact with outgroups was more commonplace, norms supported such positive interactions between members of different groups. Thus, positive contact reduces prejudice on a macrolevel, whereby people are influenced by the behavior of others in their social context, not merely on a microscale, via individuals’ direct experience of positive contact with outgroup members. These findings reinforce the view that contact has a significant role to play in prejudice reduction, and has great policy potential as a means to improve intergroup relations, because it can simultaneously impact large numbers of people.

    Pre-operative chemotherapy is an option for patients with local advanced rectal cancer, but the response rate to pre-operative chemotherapy with oxaliplatin is still low. If the therapeutic effect of pre-operative chemotherapy could be assessed, we may be able to convert to surgery early. The purpose of the present study was to validate the correlation between the maximum standardized uptake value (SUV max ) in 18F-fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) of the primary tumor and the therapeutic effect of pre-operative chemotherapy in advanced colorectal cancer. Retrospective cohort study from January 2011 to October 2015. We examined 28 patients with pathologically confirmed sigmoid or rectal cancer that underwent pre-operative chemotherapy and surgery. The correlation between Response Index (RI), calculated as (SUV max after chemotherapy)/(SUV max before chemotherapy), and the therapeutic effect on the primary tumor in advanced colorectal cancer. The degree of differentiation (p = 0.04), SUV max in the primary tumor after chemotherapy (p = 0.02), and RI (p = 0.008) were significant predictors of the therapeutic effect in univariate analysis. The areas under the ROC curve constructed with RI and therapeutic effect was 0.77. The optimal cut-off values for the RI in the responder group was effect of chemotherapy on advanced colorectal cancer. Thus, RI is potentially useful for predicting the therapeutic effect in advanced colorectal cancer.

    The researchers conducted a communication training intervention for certified nursing assistants (CNAs). The intervention aimed at improving CNAs' therapeutic techniques for relating to agitated residents during care. This study focused on an in-depth evaluation of mealtime interactions using videos. Sixteen CNAs and 16 residents living with dementia from one long-term care facility were videotaped during mealtime interactions before and after a therapeutic communication training program. Mixed-effect Poisson regression revealed no effect of the intervention as a whole on residents' refusals, but the intervention did improve CNAs' communication. Additional analyses using specific CNAs' therapeutic communication behaviors indicated a significant negative association with refusals at post-test but not pretest. The findings suggest some communication mechanisms for how the intervention positively influenced residents' refusals.

    Objective: To evaluate the therapeutic effect of cervical Jiaji electroacupuncture on postoperative intractable hiccup of liver neoplasms. Methods: A total of 39 patients with postoperative intractable hiccup of liver neoplasms in The First Affiliated Hospital of Heilongjiang University of Chinese Medicine from May 2013 to May 2017 were collected and divided into 2 groups randomly. The electroacupuncture group included 20 cases, the control group included 19 cases. Patients in the electroacupuncture group were treated by cervical Jiaji electroacupuncture (located in C3-5, sympathetic ganglion), while the control group were treated by metoclopramide combined with chlorpromazine for three days. The therapeutic effects of two groups were compared and the onset time were recorded. Results: Total effective rates of electroacupuncture group and control group were 95.0% and 47.4%, respectively. The onset time in electroacupuncture group and control group were (14.8±3.3) h and (30.5±3.1) h, respectively ( P electroacupuncture for 3 days, 6 cases were recovered, 3 cases became better, while 1 case demonstrated no response. No serious adverse reactions were appeared in each group. Conclusion: Cervical Jiaji electroacupuncture is an effective and safe treatment for postoperative intractable hiccup of liver neoplasms, and it can be used as a remedy for intractable hiccup patients who don't respond to drug treatment.

    Previous results indicated that stress impairs learning and memory. In this research, the effects of preventive, therapeutic and regular continually running activity on chronic stress-induced memory deficit in rats were investigated. 70 male rats were randomly divided into seven groups as follows: Control, Sham, Stress-Rest, Rest-Stress, Stress-Exercise, Exercise-Stress and Exercise-Stress & Exercise groups. Chronic restraint stress was applied 6 h/day for 21days and treadmill running 1 h/day. Memory function was evaluated by the passive avoidance test. The results revealed that running activities had therapeutic effect on mid and long-term memory deficit and preventive effects on short and mid-term memory deficit in stressed rats. Regular continually running activity improved mid and long-term memory compared to Exercise-Stress group. The beneficial effects of exercise were time-dependent in stress conditions. Finally, data corresponded to the possibility that treadmill running had a more important role on treatment rather than on prevention on memory impairment induced by stress.

    Full Text Available Background and Objectives:  The application of herbal medicine has been rising in recent years. Therefore, it is logical to revise and revive these traditional drugs while identifying their mechanisms of action can result in developing new treatments for many diseases. Curcumin is the most important component of Turmeric with numerous therapeutic properties. We aimed to review the anti-inflammatory and anti-microbial properties of Curcumin and introduce it as a therapeutic molecule in the present article. Methods: In this review, 121 articles were selected from authenticated electronic resources and scientific library databases such as Pubmed, Medline, Sciencedirect, WOS, DOAJ, SID, Iranmedex, Magiran and Google Scholar search engine in which Curcumin (Turmeric had been evaluated as a therapeutic molecule from differeny aspects. Results: Our findings from the literature revealed that immune responses against infectious and inflammatory factors could be fascilitated by Curcumin. However, the low solubility in water and minimal bioavailability which may lead to poor absorbance from gastrointestinal tract, quick metabolization and elimination from blood circulation are the most important problems during oral consumption. Conclusion: According to the results of the present review article, Curcumin possesses efficient anti-inflammatory, anti-microbial, anti-viral and anti-parasitic properties. However, the low bioavailability of this substance has limited its treatment properties. Nowadays, several mechanisms have been proposed to increase the bioavailability which can improve its absorption.

  4. Effects of an acute therapeutic or rewarding dose of amphetamine on acquisition of Pavlovian autoshaping and ventral striatal dopamine signaling.

    Rewarding doses of amphetamine increase the amplitude, duration, and frequency of dopamine transients in the ventral striatum. Debate continues at the behavioral level about which component of reward, learning or incentive salience, is signaled by these dopamine transients and thus altered in addiction. The learning hypothesis proposes that rewarding drugs result in pathological overlearning of drug-predictive cues, while the incentive sensitization hypothesis suggests that rewarding drugs result in sensitized attribution of incentive salience to drug-predictive cues. Therapeutic doses of amphetamine, such as those used to treat attention-deficit hyperactivity disorder, are hypothesized to enhance the ventral striatal dopamine transients that are critical for reward-related learning and to enhance Pavlovian learning. However, the effects of therapeutic doses of amphetamine on Pavlovian learning are poorly understood, and the effects on dopamine transients are completely unknown. We determined the effects of an acute pre-training therapeutic or rewarding amphetamine injection on the acquisition of Pavlovian autoshaping in the intact rat. We also determined the effects of these doses on electrically evoked transient-like dopamine signals using fast-scan cyclic voltammetry in the anesthetized rat. The rewarding dose enhanced the amplitude and duration of DA signals, caused acute task disengagement, impaired learning for several days, and triggered incentive sensitization. The therapeutic dose produced smaller enhancements in DA signals but did not have similar behavioral effects. These results underscore the necessity of more studies using therapeutic doses, and suggest a hybrid learning/incentive sensitization model may be required to explain the development of addiction.

    To investigate the effects of TENS plus therapeutic ultrasound combinations on symptom relief, physical functionality, perceived stress levels, daytime sleepiness and neck mobility in patients with chronic neck pain (CNP). A total of 64 patients were divided into two groups as the TENS plus ultrasound group (n = 39) and the control CNP group (n = 25). The therapy comprised TENS and therapeutic ultrasound applications for 10 sessions. The control subjects were discouraged from using analgesics but were allowed to use paracetamol daily, if necessary. The Neck Disability Index (NDI), Epworth Sleepiness Scale (ESS), Perceived Stress Scale (PSS), visual analog scale (VAS) and tragus-wall/chin-manubrium distances were recorded at the baseline and after therapy. Significant improvements were detected in the TENS plus ultrasound group compared to the control CNP subjects in respect of VAS, PSS and NDI scores after the TENS plus therapeutic ultrasound therapies (all p stress levels and improving functionality in the short-term of CNP.

    The bacterial Sec protein translocation system catalyzes the transport of unfolded precursor proteins across the cytoplasmic membrane. Using a recently developed real time fluorescence-based transport assay, the effects of the number and distribution of positive charges on the transport time and transport efficiency of proOmpA were examined. As expected, an increase in the number of lysine residues generally increased transport time and decreased transport efficiency. However, the observed effects were highly dependent on the polylysine position in the mature domain. In addition, a string of consecutive positive charges generally had a more significant effect on transport time and efficiency than separating the charges into two or more charged segments. Thirty positive charges distributed throughout the mature domain resulted in effects similar to 10 consecutive charges near the N terminus of the mature domain. These data support a model in which the local effects of positive charge on the translocation kinetics dominate over total thermodynamic constraints. The rapid translocation kinetics of some highly charged proOmpA mutants suggest that the charge is partially shielded from the electric field gradient during transport, possibly by the co-migration of counter ions. The transport times of precursors with multiple positively charged sequences, or “pause sites,” were fairly well predicted by a local effect model. However, the kinetic profile predicted by this local effect model was not observed. Instead, the transport kinetics observed for precursors with multiple polylysine segments support a model in which translocation through the SecYEG pore is not the rate-limiting step of transport.

    The purpose of this study was to examine the effects of voluntary wheel running on the positive reinforcing effects of heroin in rats with an established history of drug self-administration. Rats were assigned to sedentary (no wheel) and exercise (wheel) conditions and trained to self-administer cocaine under positive reinforcement contingencies. Rats acquiring cocaine self-administration were then tested with various doses of heroin during daily test sessions. Sedentary rats self-administered more heroin than exercising rats, and this effect was greatest at low and moderate doses of heroin. These data suggest that voluntary wheel running decreases the positive reinforcing effects of heroin.

    Neovascular glaucoma (NVG) is a severe secondary glaucoma with uncontrolled intraocular pressure that leads to serious eye pain and vision loss. Presently, the therapeutic strategies for NVG are diverse, but the therapeutic effects are still not ideal. We performed a network analysis to assess the effect of multiple therapeutic strategies on the treatment of NVG patients. We searched public electronic databases through April 2017 using the following keywords "neovascular glaucoma," "iris neovascularization," "hemorrhagic glaucoma," and "random" without language restrictions. The outcome considered in the present analysis was treatment success rate. A network meta-analysis and multilevel mixed-effects logistic regression were used to compare regimens. We included 27 articles assessing a total of 1884 NVG patients in our analysis. According to the network analysis, interferon and mitomycin plus trabeculectomy (94.9%), glaucoma valve implantation (86.9%), and iris photocoagulation plus trabeculectomy (81.9%) were the most likely to improve treatment success rate in NVG patients. The multilevel logistic regression analysis showed that glaucoma valve, bevacizumab, interferon, cyclophotocoagulation, trabeculectomy, iris photocoagulation, ranibizumab, and mitomycin had advantages in terms of improving treatment success rate in NVG patients. However, the application of retinal photocoagulation and vitrectomy reduced patient treatment success rate. The regimen including mitomycin, interferon, and trabeculectomy was the most likely to improve the treatment success rate in NVG patients. The application of glaucoma valve and bevacizumab were more beneficial for improving patient treatment success rate as a surgery and as an agent, respectively.

    2012-10-01

    Owing to the intricate and multifaceted pathology of cerebral stroke, multiple drug therapy had long been suggested for effective stroke treatment. Therefore, the development of a potential new combination of drug is necessitated which can bring about desirable improved neuroprotection targeting different pathways against ischemic stroke. In this context, we hypothesize the combination effect of Piroxicam, a Non steroidal anti inflammatory drug with Ifenprodil, a NR2b selective NMDAR antagonist in animal model of cerebral ischemia. A few past studies have enumerated the neuroprotective roles of Piroxicam and Ifenprodil administered in singlet against cerebral ischemia in animal model, hence we hypothesized that by using Piroxicam and Ifenprodil in combination would provide additive neuroprotection than either of the agents used alone. In this article, we discuss our hypothesis regarding the possibility of Piroxicam and Ifenprodil as a potent combination which may have a positive therapeutic role in treatment of cerebral ischemia through its anti-inflammatory, anti-apoptotic and anti-oxidative characteristics of Piroxicam with Ifenprodil which has been proved to have neuroprotective, anticonvulsant and antinociceptive effects and has potentials for the treatment of several neuropsychiatric disorders, such as Parkinson's disease alcoholism and drug addiction.

    2014-07-01

    Type 2 diabetes is a chronic and complex disease, due to the differences among affected individuals, which affect choice of treatment. The number of drug families has increased in the last few years, and these families have widely differing mechanisms of action, which contributes greatly to the individualization of treatment according to the patient's characteristics and comorbidities. The present article discusses incretin mimetic drugs. Their development has been based on knowledge of the effects of natural incretin hormones: GLP-1 (glucagon-like peptide 1), GIP (glucose-dependent insulinotropic peptide) and dipeptidyl peptidase enzyme 4 (DPP4), which rapidly degrade them in the systemic circulation. This group is composed of 2 different types of molecules: GLP-1 analogs and DPP4 enzyme inhibitors. The benefits of these molecules include a reduction in plasma glucose without the risk of hypoglycemias or weight gain. There are a series of questions that require new studies to establish a possible association between the use of these drugs and notification of cases of pancreatitis, as well as their relationship with pancreatic and thyroid cancer. Also awaited is the publication of several studies that will provide information on the relationship between these drugs and cardiovascular risk in people with diabetes. All these questions will probably be progressively elucidated with greater experience in the use of these drugs.

    Mild cognitive impairment (MCI) is often associated with the preclinical phase of Alzheimer's disease (AD). Special scoring of word-list recall data for serial position has been suggested to improve discrimination of normal aging from dementia. We examined serial position effects in word-list recall for MCI participants compared to Alzheimer patients and controls. Individuals with MCI, like Alzheimer patients, had a diminished primacy effect in recalling words from a list. No alternative scoring system was better than standard scoring of word-list recall in distinguishing MCI patients from controls. Retention weighted scoring improved the discrimination of MCI and AD groups.

    2015-06-29

    Bee Venom (BV) has long been used in Korea to relieve pain symptoms and to treat inflammatory diseases, such as rheumatoid arthritis. The underlying mechanisms of the anti-inflammatory and analgesic actions of BV have been proved to some extent. Additionally, recent clinical and experimental studies have demonstrated that BV and BV-derived active components are applicable to a wide range of immunological and neurodegenerative diseases, including autoimmune diseases and Parkinson's disease. These effects of BV are known to be mediated by modulating immune cells in the periphery, and glial cells and neurons in the central nervous system. This review will introduce the scientific evidence of the therapeutic effects of BV and its components on several immunological and neurological diseases, and describe their detailed mechanisms involved in regulating various immune responses and pathological changes in glia and neurons.

    To present a new nursing intervention category called therapeutic enhancement. Fewer than half of North Americans follow their physician's recommendations for diet and exercise, even when such are crucial to their health or recovery. It is imperative that nurses consider new ways to promote healthy behaviours. Therapeutic enhancement is intended to provide such a fresh approach. Traditional intervention techniques focusing on education, contracts, social support and more frequent interaction with physicians appear not to be effective when used alone. Successful strategies have been multidisciplinary; and have included interventions by professional nurses who assist patients to understand their disease and the disease process and that helps them to develop disease-management and self-management skills. Therapeutic enhancement incorporates The Stages of Change Theory, Commitment to Health Theory, Motivational Interviewing techniques and instrumentation specifically designed for process evaluation of health-promoting interventions. This is a critical review of approaches that, heretofore, have not been synthesised in a single published article. Based on the commonly used Stages of Change model, therapeutic enhancement is useful for patients who are at the action stage of change. Using therapeutic enhancement as well as therapeutic strategies identified in Stages of Change Theory, such as contingency management, helping relationships, counterconditioning, stimulus control and Motivational Interviewing techniques, nursing professionals can significantly increase the chances of patients moving from action to the maintenance stage of change for a specific health behaviour. Using the nursing intervention category, therapeutic enhancement can increase caregivers' success in helping patients maintain healthy behaviours.

Findings suggest that men may be particularly sensitive to the effects of stable positive affect and negative affect on clinical pain. Future work with larger samples is needed in order to identify potential mechanisms driving the sex-specific effects of affect on pain. The current study provides novel data that suggesting that the association of positive affect, negative affect, and pain are different in men versus women with KOA. Further understanding of the difference in affective expression between men and women may lead to the development of novel therapeutic interventions and help to identify additional modifiable factors in the prevention and management of pain.

    Full Text Available Abstract Background The desired (therapeutic and undesired (side effects of methylphenidate might have underlying correlations. The aim of this study was to explore the strength and the possible sources of these correlations. Methods One hundred and fifty-seven children with ADHD (6-12 years were administered placebo and methylphenidate (0.5 mg/kg in a divided b.i.d. dose, each for a one-week period, in a double-blind, crossover trial. Therapeutic response was assessed using the Conners' Global Index for parents (CGI-Parents and teachers (CGI-Teachers, while side effects were assessed using the Barkley Side Effects Rating Scale (SERS. Results The side effect profile as assessed by the SERS was similar to that of previous studies with insomnia, decreased appetite, and headaches showing significant treatment effects (p Conclusion The greater "mood/anxiety" side effects on methylphenidate and placebo, the less the parents observe improvement of their children while treated with methylphenidate. This suggests that the correlations between "mood/anxiety" side effects and poor response to treatment may be driven by observer effects rather than biological commonalities between therapeutic and side effects of methylphenidate.

    Full Text Available Platelet-rich plasma (PRP is prepared by centrifuging fresh blood in an anticoagulant state, and harvesting the platelet-rich portion or condensing platelets. Studies have consistently demonstrated that PRP concentrates are an abundant source of growth factors, such as platelet-derived growth factor (PDGF, transforming growth factor β (TGF-β, insulin-like growth factor 1 (IGF-1, and epithelial growth factor (EGF. The complex mechanisms underlying spinal cord injury (SCI diminish intrinsic repair and neuronal regeneration. Several studies have suggested that growth factor-promoted axonal regeneration can occur for an extended period after injury. More importantly, the delivery of exogenous growth factors contained in PRP, such as EGF, IGF-1, and TGF-β, has neurotrophic effects on central nervous system (CNS injuries and neurodegenerative diseases. However, only a few studies have investigated the effects of PRP on CNS injuries or neurodegenerative diseases. According to our review of relevant literature, no study has investigated the effect of intrathecal (i.t. PRP injection into the injured spinal cord and activation of intrinsic mechanisms. In the present study, we directly injected i.t. PRP into rat spinal cords and examined the effects of PRP on normal and injured spinal cords. In rats with normal spinal cords, PRP induced microglia and astrocyte activation and PDGF-B and ICAM-1 expression. In rats with SCIs, i.t. PRP enhanced the locomotor recovery and spared white matter, promoted angiogenesis and neuronal regeneration, and modulated blood vessel size. Furthermore, a sustained treatment (a bolus of PRP followed by a 1/3 dose of initial PRP concentration exerted more favorable therapeutic effects than a single dose of PRP. Our findings suggest by i.t. PRP stimulate angiogenesis, enhancing neuronal regeneration after SCI in rats. Although PRP induces minor inflammation in normal and injured spinal cords, it has many advantages. It is an

    Botanical polysaccharides exhibit a number of beneficial therapeutic properties, and it is thought that the mechanisms involved in these effects are due to the modulation of innate immunity and, more specifically, macrophage function. In this review, we summarize our current state of understanding of the macrophage modulatory effects of botanical polysaccharides isolated from a wide array of different species of flora, including higher plants, mushrooms, lichens and algae. Overall, the primary effect of botanical polysaccharides is to enhance and/or activate macrophage immune responses, leading to immunomodulation, anti-tumor activity, wound-healing and other therapeutic effects. Furthermore, botanical and microbial polysaccharides bind to common surface receptors and induce similar immunomodulatory responses in macrophages, suggesting that evolutionarily conserved polysaccharide structural features are shared between these organisms. Thus, the evaluation of botanical polysaccharides provides a unique opportunity for the discovery of novel therapeutic agents and adjuvants that exhibit beneficial immunomodulatory properties.

    Preterm neonates below 30 weeks' gestational age undergo numerous painful procedures. Many management approaches are not appropriate for this population. Therapeutic Touch, an alternative approach based on the theory of energy medicine, has been shown to promote physiological stability in preterm neonates and reduce pain in some adult studies. The objective was to determine whether Therapeutic Touch is efficacious in decreasing pain in preterm neonates. Infants Touch (n = 27) with infant behind curtains, leaving the curtained area for the heel lance, performed by another. In the sham condition (n = 28), the therapist stood by the incubator with hands by her side. The Premature Infant Pain Profile was used for pain response and time for heart rate to return to baseline for recovery. Heart rate variability and stress response were secondary outcomes. There were no group differences in any of the outcomes. Mean Premature Infant Pain Profile scores across 2 minutes of heel lance procedure in 30-second blocks ranged from 7.92 to 8.98 in the Therapeutic Touch group and 7.64 to 8.46 in the sham group. Therapeutic Touch given immediately before and after heel lance has no comforting effect in preterm neonates. Other effective strategies involving actual touch should be considered.

    Objective Examine the therapeutic relationship with cognitive-behavioral therapists and with pharmacotherapists for youth from the Child/Adolescent Anxiety Multimodal Study (CAMS; Walkup et al., 2008). The therapeutic relationship was examined in relation to treatment outcomes. Method Participants were 488 youth (ages 7-17; 50% male) randomized to cognitive-behavioral therapy (CBT; Coping cat), pharmacotherapy (SRT; sertraline), their combination, or pill placebo. Participants met DSM-IV criteria for generalized anxiety disorder, social phobia, and/or separation anxiety disorder. The therapeutic relationship was assessed by youth-report at weeks 6 and 12 of treatment using the Child's Perception of Therapeutic Relationship scale. Outcome measures (Pediatric Anxiety Rating Scale; Clinical Global Impressions Scales) were completed by Independent Evaluators blind to condition. Results For youth who received CBT only, a stronger therapeutic relationship predicted positive treatment outcome. In contrast, the therapeutic relationship did not predict outcome for youth receiving sertraline, combined treatment, or placebo. Conclusions A therapeutic relationship may be important for anxious youth who receive CBT alone. PMID:23750468

  3. Therapeutic effects of human multilineage-differentiating stress enduring (MUSE cell transplantation into infarct brain of mice.

    Full Text Available Bone marrow stromal cells (BMSCs are heterogeneous and their therapeutic effect is pleiotropic. Multilineage-differentiating stress enduring (Muse cells are recently identified to comprise several percentages of BMSCs, being able to differentiate into triploblastic lineages including neuronal cells and act as tissue repair cells. This study was aimed to clarify how Muse and non-Muse cells in BMSCs contribute to functional recovery after ischemic stroke.Human BMSCs were separated into stage specific embryonic antigen-3-positive Muse cells and -negative non-Muse cells. Immunodeficient mice were subjected to permanent middle cerebral artery occlusion and received transplantation of vehicle, Muse, non-Muse or BMSCs (2.5×104 cells into the ipsilateral striatum 7 days later.Motor function recovery in BMSC and non-Muse groups became apparent at 21 days after transplantation, but reached the plateau thereafter. In Muse group, functional recovery was not observed for up to 28 days post-transplantation, but became apparent at 35 days post-transplantation. On immunohistochemistry, only Muse cells were integrated into peri-infarct cortex and differentiate into Tuj-1- and NeuN-expressing cells, while negligible number of BMSCs and non-Muse cells remained in the peri-infarct area at 42 days post-transplantation.These findings strongly suggest that Muse cells and non-Muse cells may contribute differently to tissue regeneration and functional recovery. Muse cells may be more responsible for replacement of the lost neurons through their integration into the peri-infarct cortex and spontaneous differentiation into neuronal marker-positive cells. Non-Muse cells do not remain in the host brain and may exhibit trophic effects rather than cell replacement.

    Malaria remains a global health problem affecting more than 515 million people all over the world including Malaysia. It is on the rise, even within unknown regions that previous to this were free of malaria. Although malaria eradication programs carried out by vector control programs are still effective, anti-malarial drugs are also used extensively for curtailing this disease. But resistance to the use of anti-malarial drugs is also increasing on a daily basis. With an increased understanding of mechanisms that cause growth, differentiation and development of malarial parasites in rodents and humans, new avenues of therapeutic approaches for controlling the growth, synchronization and development of malarial parasites are essential. Within this context, the recent discoveries related to IP3 interconnected signalling pathways, the release of Ca2+ from intracellular stores of Plasmodium, ubiquitin protease systems as a signalling pathway, and melatonin influencing the growth and differentiation of malarial parasites by its effects on these signalling pathways have opened new therapeutic avenues for arresting the growth and differentiation of malarial parasites. Indeed, the use of melatonin antagonist, luzindole, has inhibited the melatonin's effect on these signalling pathways and thereby has effectively reduced the growth and differentiation of malarial parasites. As Plasmodium has effective sensors which detect the nocturnal plasma melatonin concentrations, suppression of plasma melatonin levels with the use of bright light during the night or by anti-melatonergic drugs and by using anti-kinase drugs will help in eradicating malaria on a global level. A number of patients have been admitted with regards to the control and management of malarial growth. Patents related to the discovery of serpentine receptors on Plasmodium, essential for modulating intra parasitic melatonin levels, procedures for effective delivery of bright light to suppress plasma melatonin

    Full Text Available INTRODUCTION: Functional magnetic resonance imaging studies enable the investigation of neural correlates underlying behavioral performance. We investigate the effect of active and sham Continuous Positive Airway Pressure (CPAP treatment on working memory function of patients with Obstructive Sleep Apnea Syndrome (OSAS considering Task Positive and Default Mode networks (TPN and DMN. METHODS: An experiment with 4 levels of visuospatial n-back task was used to investigate the pattern of cortical activation in 17 men with moderate or severe OSAS before and after 2 months of therapeutic (active or sub-therapeutic (sham CPAP treatment. RESULTS: Patients with untreated OSAS had significantly less deactivation in the temporal regions of the DMN as compared to healthy controls, but activation within TPN regions was comparatively relatively preserved. After 2 months of treatment, active and sham CPAP groups exhibited opposite trends of cerebral activation and deactivation. After treatment, the active CPAP group demonstrated an increase of cerebral activation in the TPN at all task levels and of task-related cerebral deactivation in the anterior midline and medial temporal regions of the DMN at the 3-back level, associated with a significant improvement of behavioral performance, whereas the sham CPAP group exhibited less deactivation in the temporal regions of Default Mode Network and less Task Positive Network activation associated to longer response times at the 3-back. CONCLUSION: OSAS has a significant negative impact primarily on task-related DMN deactivation, particularly in the medial temporal regions, possibly due to nocturnal hypoxemia, as well as TPN activation, particularly in the right ventral fronto-parietal network. After 2 months of active nasal CPAP treatment a positive response was noted in both TPN and DMN but without compete recovery of existing behavioral and neuronal deficits. Initiation of CPAP treatment early in the course of the

    Objective To investigate the therapeutic effects of mechanical horseback riding for gait and balance parameters in post-stroke patients. Method This study was a non randomized prospective positive-controlled trial over a 12 week period. From May 2011 to October 2011, 37 stroke patients were recruited from our outpatient clinic and divided into two groups. The control group received the conventional physiotherapy while the intervention group received the conventional physiotherapy along with mechanical horseback riding therapy for 12 weeks. Outcome measurements of gait included the Functional Ambulation Category (FAC) and gait part of the Performance Oriented Mobility Assessment (G-POMA) while those of balance included the Berg Balance Scale (BBS) and the balance part of the Performance Oriented Mobility Assessment (B-POMA). These measurements were taken before and after treatment. Results There were no significant differences in the baseline characteristics and initial values between the two groups. When comparing baseline and 12 weeks post treatment in each group, the intervention group showed significant improvement on BBS (39.9±5.7 → 45.7±4.8, p=0.001) and B-POMA (10.4±2.6 → 12.6±2.1, p=0.001), but significant improvement on gait parameters. When comparing the groups, the dynamic balance category of BBS in post treatment showed significant difference (p=0.02). Conclusion This study suggests that mechanical horseback riding therapy may be an effective treatment tool for enhancing balance in adults with stroke. PMID:23342307

  9. Separating the agony from ecstasy: R(-)-3,4-methylenedioxymethamphetamine has prosocial and therapeutic-like effects without signs of neurotoxicity in mice.

    S,R(+/-)-3,4-methylenedioxymethamphetamine (SR-MDMA) is an amphetamine derivative with prosocial and putative therapeutic effects. Ongoing clinical trials are investigating it as a treatment for post-traumatic stress disorder (PTSD) and other conditions. However, its potential for adverse effects such as hyperthermia and neurotoxicity may limit its clinical viability. We investigated the hypothesis that one of the two enantiomers of SR-MDMA, R-MDMA, would retain the prosocial and therapeutic effects but with fewer adverse effects. Using male Swiss Webster and C57BL/6 mice, the prosocial effects of R-MDMA were measured using a social interaction test, and the therapeutic-like effects were assessed using a Pavlovian fear conditioning and extinction paradigm relevant to PTSD. Locomotor activity and body temperature were tracked after administration, and neurotoxicity was evaluated post-mortem. R-MDMA significantly increased murine social interaction and facilitated extinction of conditioned freezing. Yet, unlike racemic MDMA, it did not increase locomotor activity, produce signs of neurotoxicity, or increase body temperature. A key pharmacological difference between R-MDMA and racemic MDMA is that R-MDMA has much lower potency as a dopamine releaser. Pretreatment with a selective dopamine D1 receptor antagonist prevented SR-MDMA-induced hyperthermia, suggesting that differential dopamine signaling may explain some of the observed differences between the treatments. Together, these results indicate that the prosocial and therapeutic effects of SR-MDMA may be separable from the stimulant, thermogenic, and potential neurotoxic effects. To what extent these findings translate to humans will require further investigation, but these data suggest that R-MDMA could be a more viable therapeutic option for the treatment of PTSD and other disorders for which SR-MDMA is currently being investigated.

    Our purpose was to determine whether exposure to mild intermittent hypoxia leads to a reduction in the therapeutic continuous positive airway pressure required to eliminate breathing events. Ten male participants were treated with twelve 2-min episodes of hypoxia ([Formula: see text] ≈50 mmHg) separated by 2-min intervals of normoxia in the presence of [Formula: see text] that was sustained 3 mmHg above baseline. During recovery from the last episode, the positive airway pressure was reduced in a stepwise fashion until flow limitation was evident. The participants also completed a sham protocol under normocapnic conditions, which mimicked the time frame of the intermittent hypoxia protocol. After exposure to intermittent hypoxia, the therapeutic pressure was significantly reduced (i.e., 5 cmH 2 O) without evidence of flow limitation (103.4 ± 6.3% of baseline, P = 0.5) or increases in upper airway resistance (95.6 ± 15.0% of baseline, P = 0.6). In contrast, a similar decrease in pressure was accompanied by flow limitation (77.0 ± 1.8% of baseline, P = 0.001) and an increase in upper airway resistance (167.2 ± 17.5% of baseline, P = 0.01) after the sham protocol. Consistent with the initiation of long-term facilitation of upper airway muscle activity, exposure to intermittent hypoxia reduced the therapeutic pressure required to eliminate apneic events that could improve treatment compliance. This possibility, coupled with the potentially beneficial effects of intermittent hypoxia on comorbidities linked to sleep apnea, suggests that mild intermittent hypoxia may have a multipronged therapeutic effect on sleep apnea. NEW & NOTEWORTHY Our new finding is that exposure to mild intermittent hypoxia reduced the therapeutic pressure required to treat sleep apnea. These findings are consistent with previous results, which have shown that long-term facilitation of upper muscle activity can be initiated following exposure to intermittent hypoxia in humans.

    Therapeutic cannabis administration is increasingly used in Western countries due to its positive role in several pathologies. Dronabinol or tetrahydrocannabinol (THC) pills, ethanolic cannabis tinctures, oromucosal sprays or table vaporizing devices are available but other cannabinoids forms can be used. Inspired by the illegal practice of dabbing of butane hashish oil (BHO), cannabinoids from cannabis were extracted with butane gas, and the resulting concentrate (BHO) was atomized with specific vaporizing devices. The efficiency of “cannavaping,” defined as the “vaping” of liquid refills for e-cigarettes enriched with cannabinoids, including BHO, was studied as an alternative route of administration for therapeutic cannabinoids. The results showed that illegal cannavaping would be subjected to marginal development due to the poor solubility of BHO in commercial liquid refills (especially those with high glycerin content). This prevents the manufacture of liquid refills with high BHO concentrations adopted by most recreational users of cannabis to feel the psychoactive effects more rapidly and extensively. Conversely, “therapeutic cannavaping” could be an efficient route for cannabinoids administration because less concentrated cannabinoids-enriched liquid refills are required. However, the electronic device marketed for therapeutic cannavaping should be carefully designed to minimize potential overheating and contaminant generation. PMID:27228348

    Full Text Available Introduction: Rheumatoid arthritis (RA is a chronic and systemic inflammatory disease of unknown etiology. It is characterized by symmetric joint involvement with progressive deformities. This leads to limitation of motion and reduction of activity daily living (ADL. Previous reports showed the beneficial effects of therapeutic exercises in these patients in the remission phase. Methods and Materials: A clinical trial as a self-control sequential control study was designed to determine the effectiveness of a range of motion (ROM exercise program in patients with RA, referring to Rheumatology Research Center between 1994-1995. ROM of the selected joints by Goniometer, and ADL by a questionnaire was assessed in all patients in 3 phases: when entering the program, after 6 weeks of observation, and then after another 6 weeks with the therapeutic exercises. The mean difference in these 2 period were compared by student paired t test. The analysis of differences between different subgroups (job, education, etc. was done by one way variance analysis. Results: Forty patients completed the program. The mean ADL increased from 0437±0.252 before exercise to 6.69±3.06 after exercise (P<0.001, and the mean scores of ROM increased from 0.278±0.28 to 8±3.57 (P<0.0001, both statistically significant. This was more pronounced in women and in those with ankle joints involvement. The type of disease onset and duration of the disease did not influence the effects of treatment. No increase in disease activity was seen. Conclusion: This study showed the effectiveness of our ROM exercises in increasing functional capacities of patients with RA in remission phase.

    Full Text Available Abstract Most Spanish prisons provide specialised treatment for incarcerated sex offenders, both rapists and child molesters. This treatment is a cognitive-behavioural intervention that has shown relative effectiveness in previous research. With regard to offenders’ rehabilitation, recidivism assessments are necessary as a final measure of treatment effectiveness. However, the evaluation of recidivism by itself does not provide sufficient information on the treatment process and the specific effects that treated subjects could undergo. This paper aims to analyse the therapeutic effectiveness of psychological treatment provided to rapists (in general, males sentenced for committing a sexual offence against women. To this aim, a group of treated rapists (N=153 serving a sentence in prison was analysed. Using a specially designed scale (PASSO, the global therapeutic change and ten specific variables (including assertiveness, readiness to change, cognitive distortions, impulsivity, etc. were assessed. The within-subjects comparison showed that treated sex offenders improved, in therapeutic terms, globally as well as in most of the specific variables assessed (improvements not experimented by the control group. Also, different therapeutic subscales showed relevant associations between them. The findings regarding treatment effectiveness are discussed.

    Full Text Available Lenalidomide is a synthetic compound derived by modifying the chemical structure of thalidomide. It belongs to the second generation of immunomodulatory drugs (IMiDs and possesses pleiotropic properties. Even if lenalidomide has been shown to be active in the treatment of several hematologic malignancies, this review article is mostly focalized on its mode of action in multiple myeloma. The present paper is about the direct and indirect antitumor effects of lenalidomide on malignant plasmacells, bone marrow microenvironment, bone resorption and host’s immune response. The molecular mechanisms and targets of lenalidomide remain largely unknown, but recent evidence shows cereblon (CRBN as a possible mediator of its therapeutical effects.

    Chronic hepatitis C caused by infection with the hepatitis C virus(HCV)is a global health problem. HCV causes persistent infection that can lead to chronic liver diseases such as chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. The therapeutic efficacy of antiviral drugs is not optimal in patients with chronic infection; furthermore, an effective vaccine has not yet been developed. To design an effective HCV vaccine, generation of a convenient animal model of HCV infection is necessary. Recently, we used the Cre/loxP switching system to generate an immunocompetent mouse model of HCV expression, thereby enabling the study of host immune responses against HCV proteins. At present vaccine has not yet been shown to be therapeutically effective against chronic HCV infection. We examined the therapeutic effects of a recombinant vaccinia virus(rVV)encoding HCV protein in a mouse model. we generated rVVs for 3 different HCV proteins and found that one of the recombinant viruses encoding a nonstructural protein(rVV-N25)resolved pathological chronic hepatitis C symptoms in the liver. We propose the possibility that rVV-N25 immunization has the potential for development of an effective therapeutic vaccine for HCV induced chronic hepatitis. The utilization of the therapeutic vaccine can protect progress to chronic hepatitis, and as a consequence, leads to eradication of hepatocellular carcinoma. In this paper, we summarized our current study for HCV therapeutic vaccine and review the vaccine development to date.

    This repeated-session design sought to answer questions about the effectiveness of therapeutic touch in reduction of stress for 23 individuals following a natural disaster. In addition, methodological issues related to the average length of time for a therapeutic-touch treatment and a method of documenting the nonverbal interaction between subject and toucher were investigated. Findings indicate that stressed people report themselves to be less stressed following therapeutic touch (p = .05). Time of therapeutic-touch intervention varied significantly between the touchers, with a range of 6.8 to 20 minutes. Qualitative data examining the interaction of toucher and subject raised a number of questions that require further study.

We investigated whether colon-targeted delivery of PCT could enhance anti-colitic effects and how therapeutic enhancement occurred at the molecular level. Molecular effects of PCT were examined in human colon carcinoma cells and inflamed colons. The anti-colitic effects of PCT in a colon-targeted capsule (colon-targeted PCT were compared with PCT in a gelatin capsule (conventional PCT in a trinitrobenzene sulfonic acid-induced rat colitis model. Colon-targeted PCT elicited greatly enhanced recovery of the colonic inflammation. In HCT116 cells, PCT inhibited nuclear factor kappaB while activating anti-colitic transcription factors, nuclear factor-erythroid 2 (NF-E2 p45-related factor 2, and hypoxia-inducible factor-1. Colon-targeted PCT, but not conventional PCT, modulated production of the target gene products of the transcription factors in the inflamed colonic tissues. Rectal administration of PCT, which simulates the therapeutic action of colon-targeted PCT, also ameliorated rat colitis and reproduced the molecular effects in the inflamed colonic tissues. Colon-targeted delivery increased therapeutic efficacy of PCT against colitis, likely resulting from multitargeted effects exerted by colon-targeted PCT. The drug delivery technique may be useful for therapeutic optimization of anti-colitic lead compounds including natural products.

    In this thesis, a therapeutic effect of nano-diamonds (NDs) has been evidenced by investigating the role of NDs surface chemistry on their electronic properties. More precisely, the generation of reactive oxygen species from detonation NDs under ionizing radiation, which could improve current radiotherapy treatments, has been demonstrated. To this end, surface treatments facilitating electron transfer from NDs to their environment, namely hydrogenation and surface graphitization, were developed. Experimental conditions ensuring an efficient hydrogenation by hydrogen plasma were determined under ultrahigh vacuum, before being used to prepare large quantities of NDs in powder phase. A similar procedure was applied to the surface graphitization of NDs, performed by annealing under vacuum at high temperature. The impact of such surface treatments on the electronic interaction properties of NDs has been investigated under ambient air and after dispersion in water. These surface treatments induce a positive Zeta potential to NDs in water, which origin has been discussed. Finally, their interactions with human tumor cells were observed. Radiosensitization of tumor cells using NDs under gamma irradiation was demonstrated, opening new perspectives for NDs in nano-medicine. (author) [fr

    We investigated the therapeutic effects and underlying mechanisms of topical doxycycline in a benzalkonium chloride (BAC)-induced mouse dry eye model. Eye drops containing 0.025%, 0.1% doxycycline or solvent were administered to a BAC-induced dry eye model four times daily. The clinical evaluations, including tear break-up time (BUT), fluorescein staining, inflammatory index, and tear volume, were performed on days 0, 1, 4, 7, and 10. Global specimens were collected on day 10 and processed for immunofluorescent staining, TUNEL, and periodic acid-Schiff assay. The levels of inflammatory mediators in the corneas were determined by real-time PCR. The total and phosphorylated nuclear factor-κB (NF-κB) were detected by Western blot. Both 0.025% and 0.1% doxycycline treatments resulted in increased BUT, lower fluorescein staining scores, and inflammatory index on days 4, 7, and 10, while no significant change in tear volume was observed. The 0.1% doxycycline-treated group showed more improvements in decreasing fluorescein staining scores, increasing Ki-67-positive cells, and decreasing TUNEL- and keratin-10-positive cells than other groups. The mucin-filled goblet cells in conjunctivas were increased, and the expression of CD11b and levels of matrix metalloproteinase-9, IL-1β, IL-6, TNF-α, macrophage inflammatory protein-2, and cytokine-induced neutrophil chemoattractant in corneas were decreased in both doxycycline-treated groups. In addition, doxycycline significantly reduced the phosphorylation of NF-κB activated in the BAC-treated corneas. Topical doxycycline showed clinical improvements and alleviated ocular surface inflammation on BAC-induced mouse dry eye, suggesting a potential as an anti-inflammatory agent in the clinical treatment of dry eye.

    Full Text Available Abstract Background The present study was designed to evaluate the efficacy of an internet-based therapy (Interapy for Posttraumatic Stress Disorder (PTSD in a German speaking population. Also, the quality of the online therapeutic relationship, its development and its relevance as potential moderator of the treatment effects was investigated. Method Ninety-six patients with posttraumatic stress reactions were allocated at random to ten sessions of Internet-based cognitive behavioural therapy (CBT conducted over a 5-week period or a waiting list control group. Severity of PTSD was the primary outcome. Secondary outcome variables were depression, anxiety, dissociation and physical health. Follow-up assessments were conducted at the end of treatment and 3 months after treatment. Results From baseline to post-treatment assessment, PTSD severity and other psychopathological symptoms were significantly improved for the treatment group (intent-to-treat group × time interaction effect size d = 1.40. Additionally, patients of the treatment condition showed significantly greater reduction of co-morbid depression and anxiety as compared to the waiting list condition. These effects were sustained during the 3-months follow-up period. High ratings of the therapeutic alliance and low drop-out rates indicated that a positive and stable therapeutic relationship could be established online. Significant improvement of the online working alliance in the course of treatment and a substantial correlation between the quality of the online relationship at the end of treatment and treatment outcome emerged. Conclusion Interapy proved to be a viable treatment alternative for PTSD with large effect sizes and sustained treatment effects. A stable and positive online therapeutic relationship can be established through the Internet which improved during the treatment process.

    Full Text Available This pilot study examined the effects of Therapeutic Clowning on inpatients in a pediatric rehabilitation hospital. Ten disabled children with varied physical and verbal expressive abilities participated in all or portions of the data collection protocol. Employing a mixed-method, single-subject ABAB study design, measures of physiological arousal, emotion and behavior were obtained from eight children under two conditions—television exposure and therapeutic clown interventions. Four peripheral autonomic nervous system (ANS signals were recorded as measures of physiological arousal; these signals were analyzed with respect to measures of emotion (verbal self reports of mood and behavior (facial expressions and vocalizations. Semistructured interviews were completed with verbally expressive children (n = 7 and nurses of participating children (n = 13. Significant differences among children were found in response to the clown intervention relative to television exposure. Physiologically, changes in ANS signals occurred either more frequently or in different patterns. Emotionally, children's (self and nurses' (observed reports of mood were elevated positively. Behaviorally, children exhibited more positive and fewer negative facial expressions and vocalizations of emotion during the clown intervention. Content and themes extracted from the interviews corroborated these findings. The results suggest that this popular psychosocial intervention has a direct and positive impact on hospitalized children. This pilot study contributes to the current understanding of the importance of alternative approaches in promoting well-being within healthcare settings.

    Protein therapeutics occupy a very significant position in the biopharmaceutical market. In addition to the preclinical, clinical and post marketing challenges common to other drugs, unwanted immunogenicity is known to affect efficacy and/or safety of most biotherapeutics. A standard set of immunogenicity risk factors are routinely used to inform monitoring strategies in clinical studies. A number of in-silico, in vivo and in vitro approaches have also been employed to predict immunogenicity of biotherapeutics, but with limited success. Emerging data also indicates the role of immune tolerance mechanisms and impact of several product-related factors on modulating host immune responses. Thus, a comprehensive discussion of the impact of innate and adaptive mechanisms and molecules involved in induction of host immune responses on immunogenicity of protein therapeutics is needed. A detailed understanding of these issues is essential in order to fully exploit the therapeutic potential of this class of drugs. This Roundtable Session was designed to provide a common platform for discussing basic immunobiological and pharmacological issues related to the role of biotherapeutic-associated risk factors, as well as host immune system in immunogenicity against protein therapeutics. The session included overview presentations from three speakers, followed by a panel discussion with audience participation. Copyright © 2012. Published by Elsevier Ltd.. All rights reserved.

    Recent research on psychedelics and hypnosis demonstrates the value of both methods in the treatment of a range of psychopathologies with overlapping applications and neurophenomenological features. The potential of harnessing the power of suggestion to influence the phenomenological response to psychedelics toward more therapeutic action has remained unexplored in recent research and thereby warrants empirical attention. Here we aim to elucidate the phenomenological and neurophysiological similarities and dissimilarities between psychedelic states and hypnosis in order to revisit how contemporary knowledge may inform their conjunct usage in psychotherapy. We review recent advances in phenomenological and neurophysiological research on psychedelics and hypnosis, and we summarize early investigations on the coupling of psychedelics and hypnosis in scientific and therapeutic contexts. Results/outcomes: We highlight commonalities and differences between psychedelics and hypnosis that point to the potential efficacy of combining the two in psychotherapy. We propose multiple research paths for coupling these two phenomena at different stages in the preparation, acute phase and follow-up of psychedelic-assisted psychotherapy in order to prepare, guide and integrate the psychedelic experience with the aim of enhancing therapeutic outcomes. Harnessing the power of suggestion to modulate response to psychedelics could enhance their therapeutic efficacy by helping to increase the likelihood of positive responses, including mystical-type experiences.

    Full Text Available Background: Antipsychotic-induced weight gain (AIWG and other adverse metabolic effects represent serious side effects faced by many patients with psychosis that can lead to numerous comorbidities and which reduce the lifespan. While the pathophysiology of AIWG remains poorly understood, numerous studies have reported a positive association between AIWG and the therapeutic benefit of antipsychotic medications.Objectives: To review the literature to (1 determine if AIWG is consistently associated with therapeutic benefit and (2 investigate which variables may mediate such an association.Data Sources: MEDLINE, Google Scholar, Cochrane Database and PsycINFO databases were searched for articles containing all the following exploded MESH terms: schizophrenia [AND] antipsychotic agents/neuroleptics [AND] (weight gain [OR] lipids [OR] insulin [OR] leptin [AND] treatment outcome. Results were limited to full-text, English journal articles.Results: Our literature search uncovered 31 independent studies which investigated an AIWG-therapeutic benefit association with a total of 6063 enrolled individuals diagnosed with schizophrenia or another serious mental illness receiving antipsychotic medications. Twenty-two studies found a positive association while, 10 studies found no association and one study reported a negative association. Study variables including medication compliance, sex, ethnicity, or prior antipsychotic exposure did not appear to consistently affect the AIWG-therapeutic benefit relationship. In contrast, there was some evidence that controlling for baseline BMI/psychopathology, duration of treatment and specific agent studied [i.e., olanzapine (OLZ or clozapine (CLZ] strengthened the relationship between AIWG and therapeutic benefit.Limitations: There were limitations of the reviewed studies in that many had small sample sizes, and/or were retrospective. The heterogeneity of the studies also made comparisons difficult and publication bias

    To evaluate the therapeutic effect of 131 I in treatment of patients with hyperthyroidism and analysis the factors that influence the effect, 230 cases of hyperthyroidism were treated with 131 I, and were followed-up at 1.5, 3, 6, 12 months and even longer time after 131 I radiotherapy. The serum levels of FT3, FT4 and TSH were detected in all cases. The results showed that 181 patients were cured (78.6%), 22 patients were improved (9.5%), 23 cases developed early hypothyroidism(10.0%),and 4 cases developed later hypothyroidism. 12 cases in 27 patients with hypothyroidism treated with thyroxin were recovered, but the other 15 cases need to be given permanent treatment. The factors which influence 131 I radiotherapeutic effect include the patient age, course of disease,application of ATD, size and quality of thyroid, and the level of thyroid hormone. The patients should be followed up to prevent occurrence of hypothyroidism. The early hypothyroidism should be treated in order to decrease the permanent hypothyroidism rate. (authors)

  10. The therapeutic alliance: a psychoanalytic perspective.

    Psychoanalysis has long distinguished between the transference neurosis and that part of the communication between therapist and patient which depends upon a relatively intact part of the patient's ego. It has been proposed that it is this capacity of the patient that sustains the difficult work of dealing with communications which are the consequence of transference, and which often threaten the viability of the treatment. This quality has been referred to variously as the unobjectionable positive transference, rational transference, mature transference, therapeutic alliance and working alliance. The ever broadening scope of Psychoanalysis, along with our greater knowledge of early childhood development, has enhanced our understanding of the many influences affecting the treatment alliances. Newer views of the transference, which stress the significance of the therapists' contributions to the therapeutic dyad, make it clear that the therapeutic alliance can no longer be explained as some simple, reality based, conflict free, motivating force. It involves, rather, a complex interaction of several factors, to each of which one must add the therapists' reciprocal reactions. Psychotherapy outcome research will need to take all of these factors into consideration.

    The purpose of this study was to evaluate the impact of a three-day therapeutic education programme on perceived competence, self-management behaviours (i.e. physical activity, diet and medication) and glycaemic control among adults with type 2 diabetes. A total of 120 participants were included in this randomized, wait list control group trial. The results confirm that therapeutic education may be a powerful healthcare intervention to improve lifestyle and health status of people with type 2 diabetes. We observed that the education programme used in this study generated positive changes in glycaemic control and adherence to physical activity and diet after three months follow-up. Furthermore, the intervention positively impacted participants' perceived competence towards physical activity and diet. The latter finding is of particular importance, given that perceived competence has been found to be involved in long-term adherence to self-management behaviours.

    The therapeutic effect of an intraarticular injection of hydroxyapatite particles labeled with Holmium-166 ( Ho 166 HA) was evaluated. For this evaluation 72 antigen-induced arthritis rats; the arthritis was induced by an intraarticular injection of a suspension of ovoalbumin and Freund's adjuvant complete. The 72 rats were divided in three groups: control group, acute arthritis group and chronic arthritis group. The evaluation of the therapeutic effect was achieved by the measuring of the perimeter of the arthritic knee joint in different days after the intraarticular injection of 0,5 μCi of Ho 166 -HA (day 0, 4, 9, 14, 19, 30). Also a biological distribution study was done at 4, 24 and 48 hours in different organs, through the counting of its radiation. The results of the biological distribution showed that a very high percent of the injected activity remains inside the joint, with minimal activity in other organs, which indicates that the extra articular leakage is very low. The evaluation of the articular perimeter, demonstrated that Ho 166 -HA has a therapeutic effect , which was shown by comparing the control group (6.42 ±0.43 cm right knee; 6.14 ±0.31 cm left knee) with the acute arthritis group (5.11 ±0.3 cm right knee; 4.95 ±0.39 cm left knee) with significantly statistical values (p≤0,01); also the control group was compared with the chronic arthritis group (5.6 ±0.56 cm right knee; 5.47 ±0.51 cm left knee), with significantly statistical values (p≤0,01). This therapeutic effect was evident too when evaluating the measure of the articular perimeter in acute and chronic arthritis groups through the time with significantly statistical values (p≤0,01). In conclusion the hydroxyapatite particles labeled with Holmium-166 are biologically stable in vivo and have a therapeutic effect in the treatment of acute and chronic arthritis in rats [es

    Reiki is an ancient form of Japanese healing. While this healing method is widely used for a variety of psychologic and physical symptoms, evidence of its effectiveness is scarce and conflicting. The purpose of this systematic review was to try to evaluate whether Reiki produces a significant treatment effect. Studies were identified using an electronic search of Medline, EMBASE, Cochrane Library, and Google Scholar. Quality of reporting was evaluated using a modified CONSORT Criteria for Herbal Interventions, while methodological quality was assessed using the Jadad Quality score. Two (2) researchers selected articles based on the following features: placebo or other adequate control, clinical investigation on humans, intervention using a Reiki practitioner, and published in English. They independently extracted data on study design, inclusion criteria, type of control, sample size, result, and nature of outcome measures. The modified CONSORT Criteria indicated that all 12 trials meeting the inclusion criteria were lacking in at least one of the three key areas of randomization, blinding, and accountability of all patients, indicating a low quality of reporting. Nine (9) of the 12 trials detected a significant therapeutic effect of the Reiki intervention; however, using the Jadad Quality score, 11 of the 12 studies ranked "poor." The serious methodological and reporting limitations of limited existing Reiki studies preclude a definitive conclusion on its effectiveness. High-quality randomized controlled trials are needed to address the effectiveness of Reiki over placebo.

    Objective: To evaluate the therapeutic effect of adipose-derived mesenchymal stem cells on radiation enteritis. Methods: A total of 52 male Sprague-Dawley rats were used in the present study. Herein, 46 rats were randomly selected and irradiated with a dose of 15 Gy at their abdomens. Two hours post-irradiation, 23 rats were randomly selected and infused intraperitoneally with adipose-derived mesenchymal stem cells in passage 6 from young-female donor. The other 23 rats were intraperitoneally infused with PBS. The rest 6 rats were set as normal control. During the first 10 days post-irradiation, peripheral blood-samples from irradiated rats were harvested for testing the levels of IL-10 in serum using ELISA assay. Additionally, after isolating the thymic cells and peripheral blood mononuclear cells, the percentages of CD4/CD25/Foxp(3)-positive regulatory T cells in thymus and peripheral blood were tested by flow-cytometry. Finally, infiltration of inflammatory cells and deposition of collagens within irradiated small intestine were analyzed by H&E staining and Masson Trichrome staining, respectively. Based on the MPO-immunohistochemistry staining, the type of infiltrated cells was identified. The Kaplan-Meier method was used for analyzing the survival rate of irradiated rats. Results: During a period of 30 days post-irradiation, the irradiated rats receiving adipose-derived mesenchymal stem cells survived longer than those receiving PBS (t = 4.53, P < 0.05). Compared to the irradiated rats with PBS-treatment, adipose-derived mesenchymal stem cells could elevate the level of IL-10 in serum (7 d: t = 13.93, P < 0.05) and increase the percentages of CD4/CD25/Foxp(3)-positive regulatory T cells in both peripheral blood (3.5 d: t = 7.72, 7 d: t = 11.11, 10 d: t = 6.99, P < 0.05) and thymus (7 d: t = 16.17, 10 d: t = 12.12, P < 0.05). Moreover, infiltration of inflammatory cells and deposition of collagens within irradiated small intestine were mitigated by adipose

    Patients have to discontinue the use of oral iron therapy due to the development of side effects and lack of long-term adherence to medication for iron deficiency anemia. This study aimed to evaluate the therapeutic effectiveness, safety, and cost of intravenous iron sucrose therapy. The computerized database and medical records of 453 patients diagnosed with iron deficiency anemia who received intravenous iron sucrose therapy for iron deficiency anemia between 2004 and 2008 were reviewed. The improvement of hematologic parameters and cost of therapy were evaluated 4 weeks after therapy. 453 patients (443 females, 10 males; age: 44.2 +/- 12.3 years) received iron sucrose therapy. Mean hemoglobin, hematocrit, and mean corpuscular volume values were 8.2 +/- 1.4 g/dL, 26.9 +/- 3.8%, and 66.1 +/- 7.8 fL, respectively, before therapy and 11.5 +/- 1.0 g/dL, 35.8 +/- 2.5%, 76.5 +/- 6.1 fL, respectively, after therapy (P 50%). The mean cost of therapy was 143.07 +/- 29.13 US dollars. The therapy was well tolerated. Although the cost of intravenous iron sucrose therapy may seem high, a lack of adherence to therapy and side effects including gastrointestinal irritation during oral iron therapy were not experienced during intravenous therapy.

    Delay discounting is the process by which the value of an expected reward decreases as the delay to obtaining that reward increases. Individuals with higher discounting rates tend to prefer smaller immediate rewards over larger delayed rewards. Previous research has indicated that personality can influence an individual's discounting rates, with higher levels of Extraversion predicting a preference for immediate gratification. The current study examined how this relationship would be influenced by situational mood inductions. While main effects were observed for both Extraversion and cognitive ability in the prediction of discounting rates, a significant interaction was also observed between Extraversion and positive affect. Extraverted individuals were more likely to prefer an immediate reward when first put in a positive mood. Extraverts thus appear particularly sensitive to impulsive, incentive-reward-driven behavior by temperament and by situational factors heightening positive affect.

    Nanotechnology-based drug delivery systems can resolve the poor bioavailability issue allied with curcumin. The therapeutic potential of curcumin can be enhanced by making nanocomposite preparation of curcumin with metal oxide nanoparticles, poly lactic-co-glycolic acid (PLGA) nanoparticles and solid lipid nanoparticles that increases its bioavailability in the tissue. Curcumin has manifold therapeutic effects which include antidiabetic, antihypertensive, anticancer, anti-inflammatory and antimicrobial properties. Curcumin can inhibit diabetes, heavy metal and stress-induced hypertension with its antioxidant, chelating and inhibitory effects on the pathways that lead to hypertension. Curcumin is an anticancer agent that can prevent abnormal cell proliferation. Nanocurcumin is an improved form of curcumin with enhanced therapeutic properties due to improved delivery to the diseased tissue, better internalization and reduced systemic elimination. Curcumin has multiple pharmacologic effects, but its poor bioavailability reduces its therapeutic effects. By conjugating curcumin to metal oxide nanoparticles or encapsulation in lipid nanoparticles, dendrimers, nanogels and polymeric nanoparticles, the water solubility and bioavailability of curcumin can be improved and thus increase its pharmacological effectiveness. © 2016 Royal Pharmaceutical Society.

    There is growing concern internationally about the prevalence of mental health problems among school-aged children and their access to specialist services. School psychologists (SPs) may be one group of professionals well-positioned to support the well-being of children and young people, due to their position as applied psychologists working within educational settings and their capability to deliver therapeutic interventions. This research considers findings from a large scale, United Kingdom (UK)-wide survey of the views of SPs (N = 455) about facilitators and barriers to the provision of therapeutic interventions to children and young people. Principal Components Analyses of ranked questionnaire responses yielded three components: The role of the SP; training and practice; and support and psychology service context. Quantitative findings were then triangulated, using qualitative responses from the survey. Greater direction and clarification of the role of the SP as a provider of therapeutic interventions is recommended, particularly given the diverse roles undertaken by SPs and competing demands, particularly from assessment activities.

    Full Text Available In this review, several glycosaminoglycan analogs obtained from different marine invertebrate are reported. The structure, biological activity and mechanism of action of these unique molecules are detailed reviewed and exemplified by experiments in vitro and in vivo. Among the glycans studied are low-sulfated heparin-like polymers from ascidians, containing significant anticoagulant activity and no bleeding effect; dermatan sulfates with significant neurite outgrowth promoting activity and anti-P-selectin from ascidians, and a unique fucosylated chondroitin sulfate from sea cucumbers, possessing anticoagulant activity after oral administration and high anti P- and L-selectin activities. The therapeutic value and safety of these invertebrate glycans have been extensively proved by several experimental animal models of diseases, including thrombosis, inflammation and metastasis. These invertebrate glycans can be obtained in high concentrations from marine organisms that have been used as a food source for decades, and usually obtained from marine farms in sufficient quantities to be used as starting material for new therapeutics.

    H Akiko Popiel

    Full Text Available The polyglutamine (polyQ diseases such as Huntington's disease (HD, are neurodegenerative diseases caused by proteins with an expanded polyQ stretch, which misfold and aggregate, and eventually accumulate as inclusion bodies within neurons. Molecules that inhibit polyQ protein misfolding/aggregation, such as Polyglutamine Binding Peptide 1 (QBP1 and molecular chaperones, have been shown to exert therapeutic effects in vivo by crossing of transgenic animals. Towards developing a therapy using these aggregation inhibitors, we here investigated the effect of viral vector-mediated gene therapy using QBP1 and molecular chaperones on polyQ disease model mice. We found that injection of adeno-associated virus type 5 (AAV5 expressing QBP1 or Hsp40 into the striatum both dramatically suppresses inclusion body formation in the HD mouse R6/2. AAV5-Hsp40 injection also ameliorated the motor impairment and extended the lifespan of R6/2 mice. Unexpectedly, we found even in virus non-infected cells that AAV5-Hsp40 appreciably suppresses inclusion body formation, suggesting a non-cell autonomous therapeutic effect. We further show that Hsp40 inhibits secretion of the polyQ protein from cultured cells, implying that it inhibits the recently suggested cell-cell transmission of the polyQ protein. Our results demonstrate for the first time the therapeutic effect of Hsp40 gene therapy on the neurological phenotypes of polyQ disease mice.

    Full Text Available Abstract Background Some drugs have a narrow therapeutic range and require monitoring and dose adjustments to optimize their efficacy and safety. Computerized clinical decision support systems (CCDSSs may improve the net benefit of these drugs. The objective of this review was to determine if CCDSSs improve processes of care or patient outcomes for therapeutic drug monitoring and dosing. Methods We conducted a decision-maker-researcher partnership systematic review. Studies from our previous review were included, and new studies were sought until January 2010 in MEDLINE, EMBASE, Evidence-Based Medicine Reviews, and Inspec databases. Randomized controlled trials assessing the effect of a CCDSS on process of care or patient outcomes were selected by pairs of independent reviewers. A study was considered to have a positive effect (i.e., CCDSS showed improvement if at least 50% of the relevant study outcomes were statistically significantly positive. Results Thirty-three randomized controlled trials were identified, assessing the effect of a CCDSS on management of vitamin K antagonists (14, insulin (6, theophylline/aminophylline (4, aminoglycosides (3, digoxin (2, lidocaine (1, or as part of a multifaceted approach (3. Cluster randomization was rarely used (18% and CCDSSs were usually stand-alone systems (76% primarily used by physicians (85%. Overall, 18 of 30 studies (60% showed an improvement in the process of care and 4 of 19 (21% an improvement in patient outcomes. All evaluable studies assessing insulin dosing for glycaemic control showed an improvement. In meta-analysis, CCDSSs for vitamin K antagonist dosing significantly improved time in therapeutic range. Conclusions CCDSSs have potential for improving process of care for therapeutic drug monitoring and dosing, specifically insulin and vitamin K antagonist dosing. However, studies were small and generally of modest quality, and effects on patient outcomes were uncertain, with no convincing

    Full Text Available Cardiac glycosides have been used for congestive heart failure and certain cardiac arrhythmias for more than 200 years. Despite the introduction of a variety of new classes of drugs for the management of heart failure, specifically angiotensin-converting enzyme (ACE inhibitors, b-adrenergic antagonists (bblockers, and the aldosterone antagonist spironolactone, digoxin continues to have an important role in long-term outpatient management. However, a narrow margin exists between therapeutic and toxic doses of digoxin, resulting in a high incidence of digoxin toxicity in clinical practice.A wide variety of placebo-controlled clinical trials have unequivocally shown that treatment with digoxin can improve symptoms, quality of life, and exercise tolerance in patients with mild, moderate, or severe heart failure. The clinical relevance of digoxin therapeutic monitoring is also proved but the SDC (Serum Digoxin Conentrations required for optimal clinical efficacy and acceptable toxicity remains controversial. In the last years, international guidelines recommend 1.2 ng/mL as acceptable high level.In this bibliographic synthesis, we aim to collect pertinent informations from MedLine database about exposure-effect relationship in order to assess the evidence level scientific of new digoxin therapeutic monitoring.

    [Purpose] The intensity of therapeutic physical exercise is complex and sometimes controversial in patients with neural injuries. This review assessed whether therapeutic physical exercise is beneficial according to the intensity of the physical exercise. [Methods] The authors identified clinically or scientifically relevant articles from PubMed that met the inclusion criteria. [Results] Exercise training can improve body strength and lead to the physiological adaptation of skeletal muscles and the nervous system after neural injuries. Furthermore, neurophysiological and neuropathological studies show differences in the beneficial effects of forced therapeutic exercise in patients with severe or mild neural injuries. Forced exercise alters the distribution of muscle fiber types in patients with neural injuries. Based on several animal studies, forced exercise may promote functional recovery following cerebral ischemia via signaling molecules in ischemic brain regions. [Conclusions] This review describes several types of therapeutic forced exercise and the controversy regarding the therapeutic effects in experimental animals versus humans with neural injuries. This review also provides a therapeutic strategy for physical therapists that grades the intensity of forced exercise according to the level of neural injury.

    Transcranial magnetic stimulation (TMS) is an effective method used to diagnose and treat many neurological disorders. Although repetitive TMS (rTMS) has been used to treat a variety of serious pathological conditions including stroke, depression, Parkinson’s disease, epilepsy, pain, and migraines, the pathophysiological mechanisms underlying the effects of long-term TMS remain unclear. In the present review, the effects of rTMS on neurotransmitters and synaptic plasticity are described, including the classic interpretations of TMS effects on synaptic plasticity via long-term potentiation and long-term depression. We also discuss the effects of rTMS on the genetic apparatus of neurons, glial cells, and the prevention of neuronal death. The neurotrophic effects of rTMS on dendritic growth and sprouting and neurotrophic factors are described, including change in brain-derived neurotrophic factor concentration under the influence of rTMS. Also, non-classical effects of TMS related to biophysical effects of magnetic fields are described, including the quantum effects, the magnetic spin effects, genetic magnetoreception, the macromolecular effects of TMS, and the electromagnetic theory of consciousness. Finally, we discuss possible interpretations of TMS effects according to dynamical systems theory. Evidence suggests that a rTMS-induced magnetic field should be considered a separate physical factor that can be impactful at the subatomic level and that rTMS is capable of significantly altering the reactivity of molecules (radicals). It is thought that these factors underlie the therapeutic benefits of therapy with TMS. Future research on these mechanisms will be instrumental to the development of more powerful and reliable TMS treatment protocols. PMID:26136672

    There is emerging evidence for a positivity effect in healthy aging, which describes an age-specific increased focus on positive compared to negative information. Life-span researchers have attributed this effect to the selective allocation of cognitive resources in the service of prioritized emotional goals. We explored the basic principles of this assumption by assessing selective attention and memory for visual stimuli, differing in emotional content and self-relevance, in young and old participants. To specifically address the impact of cognitive control, voluntary attentional selection during the presentation of multiple-item displays was analyzed and linked to participants' general ability of cognitive control. Results revealed a positivity effect in older adults' selective attention and memory, which was particularly pronounced for self-relevant stimuli. Focusing on positive and ignoring negative information was most evident in older participants with a generally higher ability to exert top-down control during visual search. Our findings highlight the role of controlled selectivity in the occurrence of a positivity effect in aging. Since the effect has been related to well-being in later life, we suggest that the ability to selectively allocate top-down control might represent a resilience factor for emotional health in aging.

  12. Therapeutic effects of lentivirus-mediated shRNA targeting of cyclin D1 in human gastric cancer

    Gastric cancer is the second most common cause of cancer-related death in males and the fourth in females. Traditional treatment has poor prognosis because of recurrence and systemic side effects. Therefore, the development of new therapeutic strategies is an important issue. Lentivirus-mediated shRNA stably inhibits target genes and can efficiently transduce most cells. Since overexpressed cyclin D1 is closely related to human gastric cancer progression, inhibition of cyclin D1 using specific targeting could be an effective treatment method of human gastric cancer. The therapeutic effect of lentivirus-mediated shRNA targeting of cyclin D1 (ShCCND1) was analyzed both in vitro and in vivo experiments. In vitro, NCI-N87 cells with downregulation of cyclin D1 by ShCCND1 showed significant inhibition of cell proliferation, cell motility, and clonogenicity. Downregulation of cyclin D1 in NCI-N87 cells also resulted in significantly increased G1 arrest and apoptosis. In vivo, stable NCI-N87 cells expressing ShCCND1 were engrafted into nude mice. Then, the cancer-growth inhibition effect of lentivirus was confirmed. To assess lentivirus including ShCCND1 as a therapeutic agent, intratumoral injection was conducted. Tumor growth of the lentivirus-treated group was significantly inhibited compared to growth of the control group. These results are in accordance with the in vitro data and lend support to the mitotic figure count and apoptosis analysis of the tumor mass. The lentivirus-mediated ShCCND1 was constructed, which effectively inhibited growth of NCI-N87-derived cancer both in vitro and in vivo. The efficiency of shRNA knockdown and variation in the degree of inhibition is mediated by different shRNA sequences and cancer cell lines. These experimental results suggest the possibility of developing new gastric cancer therapies using lentivirus-mediated shRNA

  13. Study and evaluation of radiometry in photo therapeutic treatment of the neonatal hyperbilirubinaemia

    Phototherapy is a procedure established more than 50 years ago in the treatment of the newborn jaundice. However there is no a standard method to quantify the photo therapeutic dose in published clinical studies, hindering the comparison of previous studies on photo therapeutic effectiveness, as well as the establishment of safe and predictable doses. The photo therapeutic dose depends, among other factors, on the effective mean irradiance produced by the photo therapeutic unit. There are no standard procedures, however, neither to quantify the effective irradiance, nor to estimate the mean effective irradiance. As a consequence, large measurement variations in a same photo therapeutic unit are observed using different commercially available radiometers, as a consequence of the vast diversity of spectral responsivities of the instruments. An objective of this work was to adapt and to apply the bases of the wideband ultraviolet radiometry to quantify the available irradiance from photo therapeutic units, establishing procedures that allow us to compare measured irradiances from different sources, using radiometers presenting different spectral responsivities. Another objective was to characterize samples of photo therapeutic units commonly used, focusing the problem of the estimation of the effective mean irradiance from photo therapeutic units, proposing a method to estimate of the effective irradiance from focused sources. The experimental results allow us to conclude that it is not only necessary to standardize the photo therapeutic radiometry, but also the method of estimation of the effective mean irradiance.

    2014-09-01

    Conclusion: The protective effect of cannabis extract is more pronounced in group taking cannabis before DMNA. Cannabinoids might exert their anti-tumor effects by the direct induction of apoptosis and can decrease telomerase activity by inhibiting the expression of the TERT gene. Coordination between inhibition of telomerase activity and induction of apoptosis might be a potential therapeutic agent for cancer treatment.

    Genomic data from human epidermal growth factor receptor 2-positive (HER2+) tumors were analyzed to assess the association between intrinsic subtype and clinical outcome in a large, well-annotated patient cohort. Samples from the NCCTG (Alliance) N9831 trial were analyzed using the Prosigna algorithm on the NanoString platform to define intrinsic subtype, risk of recurrence scores, and risk categories for 1392 HER2+ tumors. Subtypes were evaluated for recurrence-free survival (RFS) using Kaplan-Meier and Cox model analysis following adjuvant chemotherapy (n = 484) or chemotherapy plus trastuzumab (n = 908). All statistical tests were two-sided. Patients with HER2+ tumors from N9831 were primarily scored as HER2-enriched (72.1%). These individuals received statistically significant benefit from trastuzumab (hazard ratio [HR] = 0.68, 95% confidence interval [CI] = 0.52 to 0.89, P = .005), as did the patients (291 of 1392) with luminal-type tumors (HR = 0.52, 95% CI = 0.32 to 0.85, P = .01). Patients with basal-like tumors (97 of 1392) did not have statistically significantly better RFS when treated with trastuzumab and chemotherapy compared with chemotherapy alone (HR = 1.06, 95% CI = 0.53 to 2.13, P = .87). The majority of clinically defined HER2-positive tumors were classified as HER2-enriched or luminal using the Prosigna algorithm. Intrinsic subtype alone cannot replace conventional histopathological evaluation of HER2 status because many tumors that are classified as luminal A or luminal B will benefit from adjuvant trastuzumab if that subtype is accompanied by HER2 overexpression. However, among tumors that overexpress HER2, we speculate that assessment of intrinsic subtype may influence treatment, particularly with respect to evaluating alternative therapeutic approaches for that subset of HER2-positive tumors of the basal-like subtype. © The Author 2016.

    Chewing is crushing food not only to aid swallowing and digestion, but also to help stress relief and regulate cognitive function, especially in attention. It is well known that chewing gum is used for sleepiness prevention during work, learning, and driving, suggesting a link between chewing and sustained attention. We hypothesized that chewing elevates attention and/or alertness, leading to improvements in cognitive performance. We carried out a systematic review of the PubMed database. We inspected the attributes of effects on attention in studies investigating the effects of chewing on attention or alertness conducted with pre-post design in healthy subjects, except elderly. We identified 151 references, 22 of which were included: 14 (64%) showed positive attributes of effects on attention, 1 (5%) showed negative attributes of effects on attention, 5 (23%) showed both positive and negative attributes of effects on attention, and 2 (9%) showed no significant attributes of effects on attention. Thus, positive attributes of effects of chewing on attention, especially on sustained attention, were shown in over half of the reports. These effects also appeared with improvement in mood and stress relief and were influenced by time-on-task effect. Further studies are needed, but chewing could be useful for modifying cognitive function. PMID:26075234

    Full Text Available In this study, female rats induced with chemical cystitis were administered the hormone human choriogonadotropin (HCG, and it was aimed to reveal the usefulness of HCG in the treatment of interstitial cystitis/bladder pain syndrome. The materials for this study were 32 Wistar albino female rats. The study groups were formed as follows: the cystitis group (Group 1, the cystitis + HCG protection group (Group 2, the cystitis + HCG treatment group (Group 3, and the control group (Group 4, with eight rats in each group. In this study, blood and urine samples were taken from the rats, they were euthanized, and their bladders were removed for glutathione, malondialdehyde, tumor necrosis factor alpha, and interferon gamma measurements. It was observed that tissue damage in Group 2 was lower than that in the other two groups. Glutathione levels in Groups 2 and 4 were significantly higher than in Groups 1 and 3 (p = 0.01. Malondialdehyde levels of Groups 2 and 4 were significantly lower than the values in Groups 1 and 3 (p < 0.001. When the cystitis groups were compared in terms of their interferon gamma and tumor necrosis factor alpha levels, the lowest interferon gamma and tumor necrosis factor alpha levels were detected in Group 3. It was found that HCG has positive effects on experimental cystitis in rats. This study revealed that HCG should be researched as a therapeutic agent and formed a step for studies to be carried out on this subject.

    In this study, we examined mechanisms that underlie free-recall performance in bilinguals' first language (L1) and second language (L2) through the prism of serial-position effects. On free-recall tasks, a typical pattern of performance follows a U-shaped serial-position curve, where items from the beginning of the list (the primacy effect) and items from the end of the list (the recency effect) are recalled with higher accuracy than items from the middle of the list. The present study contrasted serial-position effects on the free-recall task in Korean-English bilinguals' L1 vs. L2 and examined the relationship between an independent working memory (WM) measure and serial-position effects in bilinguals' two languages. Results revealed stronger pre-recency (primacy and middle) effects in L1 than in L2, but similar recency effects in the two languages. A close association was observed between WM and recall performance in the pre-recency region in the L1 but not in the L2. Together, these findings suggest that linguistic knowledge constrains free-recall performance in bilinguals, but only in the pre-recency region.

Occurring in five of 1000 live-born infants globally and even more in developing countries, HIE is a serious problem that causes death in 25%–50% of affected neonates and neurological disability to at least 25% of survivors. In order to prevent the damage caused by HIE, our invention provides an effective whole-body cooling of the neonates by utilizing evaporation and an endothermic reaction. Our device is composed of basic electronics, clay pots, sand, and urea-based instant cold pack powder. A larger clay pot, lined with nearly 5 cm of sand, contains a smaller pot, where the neonate will be placed for therapeutic treatment. When the sand is mixed with instant cold pack urea powder and wetted with water, the device can extract heat from inside to outside and maintain the inner pot at 17°C for more than 24 hours with monitoring by LED lights and thermistors

    Heart failure is a leading cause of death and the development of effective and safe therapeutic agents for heart failure has been proven challenging. In this study, taking advantage of larval zebrafish, we developed a zebrafish heart failure model for drug screening and efficacy assessment. Zebrafish at 2 dpf (days postfertilization) were treated with verapamil at a concentration of 200 μM for 30 min, which were determined as optimum conditions for model development. Tested drugs were administered into zebrafish either by direct soaking or circulation microinjection. After treatment, zebrafish were randomly selected and subjected to either visual observation and image acquisition or record videos under a Zebralab Blood Flow System. The therapeutic effects of drugs on zebrafish heart failure were quantified by calculating the efficiency of heart dilatation, venous congestion, cardiac output, and blood flow dynamics. All 8 human heart failure therapeutic drugs (LCZ696, digoxin, irbesartan, metoprolol, qiliqiangxin capsule, enalapril, shenmai injection, and hydrochlorothiazide) showed significant preventive and therapeutic effects on zebrafish heart failure (p failure model developed and validated in this study could be used for in vivo heart failure studies and for rapid screening and efficacy assessment of preventive and therapeutic drugs.

    SUMMARY The three main oral diseases of humans, that is caries, periodontal diseases and oral candidiasis, are associated with microbiome shifts initiated by changes in the oral environment and/or decreased effectiveness of mucosal immune surveillance. In this review we discuss the role that microbial-based therapies may have in the control of these conditions. Most investigations on the use of microorganisms for management of oral disease have been conducted with probiotic strains with some positive but very discrete clinical outcomes. Other strategies such as whole oral microbiome transplantation or modification of community function by enrichment with health-promoting indigenous oral strains may offer more promise but research in this field is still in its infancy. Any microbial-based therapeutics for oral conditions, however, are likely to be only one component within a holistic preventive strategy that should also aim at modification of the environmental influences responsible for the initiation and perpetuation of microbiome shifts associated with oral dysbiosis.

  7. Selective control of attention supports the positivity effect in aging.

    Directory of Open Access Journals (Sweden)

    Laura K Sasse

    Full Text Available There is emerging evidence for a positivity effect in healthy aging, which describes an age-specific increased focus on positive compared to negative information. Life-span researchers have attributed this effect to the selective allocation of cognitive resources in the service of prioritized emotional goals. We explored the basic principles of this assumption by assessing selective attention and memory for visual stimuli, differing in emotional content and self-relevance, in young and old participants. To specifically address the impact of cognitive control, voluntary attentional selection during the presentation of multiple-item displays was analyzed and linked to participants' general ability of cognitive control. Results revealed a positivity effect in older adults' selective attention and memory, which was particularly pronounced for self-relevant stimuli. Focusing on positive and ignoring negative information was most evident in older participants with a generally higher ability to exert top-down control during visual search. Our findings highlight the role of controlled selectivity in the occurrence of a positivity effect in aging. Since the effect has been related to well-being in later life, we suggest that the ability to selectively allocate top-down control might represent a resilience factor for emotional health in aging.

    An increasing number of tumors, including breast cancer, overexpress proteins of the epidermal growth factor receptor (EGFR) family. The interaction between family members activates signaling pathways that promote tumor progression and resistance to treatment. Human epidermal growth factor receptor type II (HER2) positive breast cancer represents a clinical challenge for current therapy. It has motivated the development of novel and more effective therapeutic EGFR family target drugs, such as tyrosine kinase inhibitors (TKIs). This review focuses on the effects of three TKIs mostly studied in HER2- positive breast cancer, lapatinib, gefitinib and neratinib. Herein, we discuss the mechanism of action, therapeutic advantages and clinical applications of these TKIs. To date, TKIs seem to be promising therapeutic agents for the treatment of HER2-overexpressing breast tumors, either as monotherapy or combined with other pharmacological agents.

  9. Photoelectric effect photon beam position monitors

    Stability of the electron orbit is of critical importance at the NSLS. Many experimenters utilizing the NSLS photon beams can take full advantage of the small transverse dimensions of the source only if the electron orbit variation is kept below 10 to 20% of the transverse electron bunch size. Clearly the first step in a program to stabilize the orbit is to develop position monitors with the required sensitivity, reliability and dynamic range. Of great importance are monitors detecting the photon beams themselves, and also monitors measuring the position of the electron beam. In this section the authors discuss photon beam position monitors utilizing the photoelectric effects, and in the following section the use of capacitively coupled pick-up electrodes to detect electron beam position will be described. In what follows they shall proceed to consider two generic types of monitor geometries (1) Gap monitors, which are designed with the idea that the fringes of the synchrotron radiation will be measured, and the hot or fundamental beam will pass through the monitor unimpeded. (2) Area monitors, which are comprised of two triangular elements nested together similar to the electrodes of a split ion chamber or the diodes described by Siddons and Kraner or Mitsuhashi et al

    The aim of this qualitative study was to explore social workers' reflections on their experience of the therapeutic encounter with victims and perpetrators of elder abuse and neglect. The research questions were as follows: How do social workers tune themselves toward the therapeutic encounter with elder abuse? How do they position themselves vis-à-vis the clients? How do social workers describe the meaning of the intervention both for the clients and for themselves? What is the added value of the therapeutic encounter in this field for the social workers? Participants were 17 experienced women social workers, who worked with abusers and with abused and neglected older adults in Israel. Data were collected via in-depth semi-structured interviews, which were later transcribed and content analyzed. Two main themes emerged from the findings, emphasizing two key aspects of the social workers' reflective process experienced during the therapeutic encounter: (a) focus on the client: "This is the journey of their lives"-reflection on the therapeutic "journey"; (b) focus on the social worker's inner and professional world: "'There is nothing to be done' is no longer in my vocabulary"-a personal and professional maturation process. The social workers expressed a positive attitude toward their elder clients. A unique dialogue developed in the therapeutic encounter, whereby the social workers considered any change as valuable if it allowed the elders a sense of control and self-worth, whereas the social workers were enriched by the elders' life experience, and matured both personally and professionally. Thus, both sides benefited from this reciprocal relationship. Implications for further research and practice are discussed. © The Author(s) 2016.

    Prior research has shown that negative emotions, even though task irrelevant, are capable of delaying a participant's response to the color in which a negative emotional word is presented, a phenomenon known as the 'emotional Stroop effect'. However, relatively little is known about whether positive emotions have a similar or an opposite effect. The current study sets out to confirm the facilitating effect of positive emotions on color naming, which is predicted by Barbara Fredrickson's 'broaden and build' theory. Our results indicate that positive emotions did facilitate such processing in both of the study's experiments. We also found a significant difference in early posterior negativity amplitudes between positive and neutral stimuli, which was related to the 'fast effect'. Overall, the study's findings suggest that positive emotions can be detected quickly and automatically, and that this kind of prioritizing facilitates the ongoing cognitive processing.

    Objective: To analyses the clinical data of 131 I in treating youngsters with Graves disease, and to explore the effective dose range which is appropriate for Chinese youngsters with Graves disease. Methods: Two hundred and thirty-four youngsters with Graves disease were selected in this study, their ages were between 8 and 17, the average quality of their thyroids was (59.0±16.5)g. According to the absorbed dose of 131 I per gram of thyroid gland, 234 patients were divided into five groups: A: 1.11- 2.59 MBq/g. The therapeutic effect was evaluated by observing after treatment. And calculate the recovery rate, the improvement rate and the incidence rate of hypothyroidism. Results: (1) One hundred and fifty-two (64.95%) patients were cured, 56 (23.93%) were much better than before and 26 (11.11%) were hypothyroid. The therapeutic effect of group B was the best in all groups. (2) The recovery rate: there was no significant difference between group B, group C and group D (χ 2 =2.68, P>0.05). The recovery rate of group B was better than group A and group E (χ 2 =10.20 and χ 2 =5.49, P 2 =1.94, P>0.05). The improvement rate of group A was the highest (χ 2 =8.74, χ 2 =6.68, χ 2 =7.01 and χ 2 =11.12, P 2 =2.71, P>0.05). Group E had the highest incidence rate of hypothyroidism (χ 2 =12.36, χ = 11.58, χ 2 =9.37 and χ 2 =4.36, P 131 I is a safe and effective therapeutic approach for youngsters with Graves disease. We suggest the absorbed dose range of 131 I per gram of thyroid gland is 1.48-2.59 MBq/g, which can obtain the better therapeutic effect and can't increase the incidence rate of hypothyroidism.

    Most previous studies on the effects of therapeutic exercise on osteoarthritis (OA) of the hip joint included participants with knee OA or postoperative participants. Moreover, although some systematic reviews recommend therapeutic exercise for hip OA, a consensus on the effective interventional frequency has not been reached. This study aimed to investigate the effects of therapeutic exercise performed at different frequencies on physical function and health-related quality of life in participants with hip OA. Individuals diagnosed with hip OA (36 women, age 42-79 years; 19 in 2009 and 17 in 2010) were recruited from the cooperating medical institutions. They were divided into two groups depending on the frequency of therapeutic exercise: fortnightly in 2009 (fortnightly group) and weekly in 2010 (weekly group). Participants in each group performed the same land-based and aquatic exercises on the same day for a total of ten sessions. Muscle strength of the lower extremity, "timed up and go" (TUG), time of one-leg standing with open eyes (TOLS), Harris Hip Score, and scores of the Medical Outcomes Survey Short Form-36 questionnaire, were measured before and after interventions. The fortnightly group had no significant changes in lower-extremity muscle strength following intervention, but the strength of all muscles in the weekly group improved significantly after intervention. Further, in both groups, TUG and TOLS of the worse side of the hip joint significantly improved after interventions. Weekly exercise improves muscle strength of the lower extremity and may therefore be an effective interventional technique for managing hip OA. In addition, in persons with hip OA, therapeutic exercise consisting of both land- and water-based exercises markedly improved physical function.

    Cervical cancer is the second most common cause of female cancer death worldwide. Persistent infection with `high risk' HPV genotypes is the major etiological factor in cervical cancer and thus effective vaccination against HPV provides an opportunity to reduce the morbidity and mortality associated with HPV. The FDA has approved two preventive vaccines to limit the spread of HPV. However, these are unlikely to impact upon HPV prevalence and cervical cancer rates for many years. Furthermore, preventive vaccines do not exert therapeutic effects on pre-existing HPV infections and HPV-associated lesions. In order to further impact upon the burden of HPV infections worldwide, therapeutic vaccines are being developed. These vaccines aim to generate a cell-mediated immune response to infected cells. This review discusses current preventive and therapeutic HPV vaccines and their future directions. PMID:20123582

    Full Text Available Pythiosis, a disease caused by the oomycete Pythium insidiosum, often presents inefficient response to chemotherapy. It is a consensus that, in spite the several therapeutic protocols, a combination of surgery, chemotherapy and immunotherapy should be used. Surgical excision requires the removal of the entire affected area, with a wide margin of safety. The use of antifungal drugs has resulted in variable results, both in vitro and in vivo, and presents low therapeutic efficiency due to differences in the agent characteristics, which differ from true fungi. Immunotherapy is a non-invasive alternative for the treatment of pythiosis, which aims at modifying the immune response of the host, thereby producing an effective response to the agent. Photodynamic therapy has emerged as a promising technique, with good activity against P. insidiosum in vitro and in vivo. However, more studies are necessary to increase the efficiency of the current treatment protocols and consequently improve the cure rates. This paper aims to conduct a review covering the conventional and recent therapeutic methods against P. insidiosum infections

    Full Text Available Transcranial magnetic stimulation (TMS is an effective method used to diagnose and treat many neurological disorders. Although repetitive TMS (rTMS has been used to treat a variety of serious pathological conditions including stroke, depression, Parkinson's disease, epilepsy, pain, and migraines, the pathophysiological mechanisms underlying the effects of long-term TMS remain unclear. In the present review, the effects of rTMS on neurotransmitters and synaptic plasticity are described, including the classic interpretations of TMS effects on synaptic plasticity via long-term potentiation (LTP and long-term depression (LTD. We also discuss the effects of rTMS on the genetic apparatus of neurons, glial cells and the prevention of neuronal death. The neurotrophic effects of rTMS on dendritic growth and sprouting and neurotrophic factors are described, including change in brain-derived neurotrophic factor (BDNF concentration under the influence of rTMS. Also, non-classical effects of TMS related to biophysical effects of magnetic fields are described, including the quantum effects, the magnetic spin effects, genetic magnetoreception, the macromolecular effects of TMS, and the electromagnetic theory of consciousness. Finally, we discuss possible interpretations of TMS effects according to dynamical systems theory. Evidence suggests that a rTMS-induced magnetic field should be considered a separate physical factor that can be impactful at the subatomic level and that rTMS is capable of significantly altering the reactivity of molecules (radicals. It is thought that these factors underlie the therapeutic benefits of therapy with TMS. Future research on these mechanisms will be instrumental to the development of more powerful and reliable TMS treatment protocols.

    BACKGROUND This study aimed to explore the therapeutic effect of external application of ligustrazine combined with holistic nursing on pressure sores, as well as the underlying mechanism. MATERIAL AND METHODS From February 2014 to March 2015, a total of 32 patients with Phase II and Phase III pressure sores were enrolled and randomly assigned to an experimental group or a control group. The clinical data were comparable between the 2 groups. In addition to holistic nursing, the patients in the experimental group received 4 weeks of continuous external application of ligustrazine, whereas patients in the control group received compound clotrimazole cream. Therapeutic effect and healing time were recorded. HaCaT cells were used as an in vitro model for mechanism analysis of the effect of ligustrazine in treating pressure sores. After culturing with different concentrations of ligustrazine or the inhibitor of AKT (LY294002) for 72 h, cell viability, clone formation numbers, and levels of phosphatidyl inositol 3-kinase (PI3K), p-AKT, and p-mammalian target of rapamycin (mTOR) were determined. RESULTS Compared to the control group, the total effective rate in the experimental group was significantly higher, and the healing time was significantly reduced. Cell viability and clone formation numbers were significantly upregulated by ligustrazine in a dose-dependent manner. Both the cell viability and clone formation numbers were significantly inhibited by application of LY294002. CONCLUSIONS Our results suggest that ligustrazine combined with holistic nursing is an effective treatment of pressure sores. The protective effect may be associated with the promotion of cell growth by activation of the PI3K/AKT pathway.

  18. The Effect of Positive Mood on Flexible Processing of Affective Information.

    2017-07-17

    Recent efforts have been made to understand the cognitive mechanisms underlying psychological resilience. Cognitive flexibility in the context of affective information has been related to individual differences in resilience. However, it is unclear whether flexible affective processing is sensitive to mood fluctuations. Furthermore, it remains to be investigated how effects on flexible affective processing interact with the affective valence of information that is presented. To fill this gap, we tested the effects of positive mood and individual differences in self-reported resilience on affective flexibility, using a task switching paradigm (N = 80). The main findings showed that positive mood was related to lower task switching costs, reflecting increased flexibility, in line with previous findings. In line with this effect of positive mood, we showed that greater resilience levels, specifically levels of acceptance of self and life, also facilitated task set switching in the context of affective information. However, the effects of resilience on affective flexibility seem more complex. Resilience tended to relate to more efficient task switching when negative information was preceded by positive information, possibly because the presentation of positive information, as well as positive mood, can facilitate task set switching. Positive mood also influenced costs associated with switching affective valence of the presented information. This latter effect was indicative of a reduced impact of no longer relevant negative information and more impact of no longer relevant positive information. Future research should confirm these effects of individual differences in resilience on affective flexibility, considering the affective valence of the presented information.

    In the RNA realm, non-Watson-Crick base pairs are abundant and can affect both the RNA 3D structure and its function. Here, we investigated the formation of RNA kissing complexes in which the loop-loop interaction is modulated by non-Watson-Crick pairs. Mass spectrometry, surface plasmon resonance, and UV-melting experiments show that the G⋅U wobble base pair favors kissing complex formation only when placed at specific positions. We tried to rationalize this effect by molecular modeling, including molecular mechanics Poisson-Boltzmann surface area (MMPBSA) thermodynamics calculations and PBSA calculations of the electrostatic potential surfaces. Modeling reveals that the G⋅U stabilization is due to a specific electrostatic environment defined by the base pairs of the entire loop-loop region. The loop is not symmetric, and therefore the identity and position of each base pair matters. Predicting and visualizing the electrostatic environment created by a given sequence can help to design specific kissing complexes with high affinity, for potential therapeutic, nanotechnology or analytical applications. © 2017 Wiley-VCH Verlag GmbH & Co.

    The presence of the Philadelphia chromosome is a poor prognosis factor in acute lymphoblastic leukemia (ALL), in both children and adults. Using molecular techniques of the gen bcr/abl, it is possible to detect the abnormality, in up to the 40% of adult patients. The unsatisfactory results with conventional chemotherapy schemes have determined the intensification of the treatments and the consideration of allogenic bone marrow transplants as the best therapeutic instance. The development of tyrosine kinase inhibitors have become a therapeutic improvement in the treatment of Philadelphia chromosome-positive ALL, being combined with chemotherapy schemes, only in a selected group of patients, even in therapeutic programs that include transplant.

    Post-irradiation effect of adrenaline and serotonin on the hemopoietic system of irradiated mice has been studied. The pharmaceuticals were injected subcutaneously 15 minutes before the X-radiation exposure at a dose of 7 Gy or immediately after it. The degree of radiation injury has been estimated from 30-day survival fraction of the animals, cell state of the bone marrow, mass of spleen, cfu quantity in the bone marrow at exo- and endocolonial growth (following implantation of bone marrow cells from mice that had been injected with these drugs to irradiated recipients). Post-irradiation effect of adrenaline turned to be weaker than that of serotonin, the latter increasing the survival rate of irradiated mice to 50%. It is stated that post-irradiation therapeutic effect of adrenaline and serotonin expressed in acceleration of the irradiated hemopoietic tissue repair can be realized under direct effect of drugs on the viable hemopoietic cells, probably, by enchancement of their proliferation

    Cancer chemoprevention is a strategy taken to retard, regress, or resist the multistep process of carcinogenesis, including the blockage of its vital morphogenetic milestones viz. normal-preneoplasia-neoplasia-metastasis. For several reasons, including safety, minimal (or no) toxicity and side-effects, and better availability, alternatives such as naturally occurring phytochemicals that are found in foods are becoming increasingly popular over synthetic drugs. Food saponins have been used in complimentary and traditional medicine against a variety of diseases including several cancers. Diosgenin, a naturally occurring steroid saponin found abundantly in legumes and yams, is a well-known precursor of various synthetic steroidal drugs that are extensively used in the pharmaceutical industry. Over the past decade, a series of preclinical and mechanistic studies have been conducted to understand the role of diosgenin as a chemopreventive/therapeutic agent against several cancers. This review highlights the biological activity of diosgenin that contributes to cancer chemoprevention and control. The anticancer mode of action of diosgenin has been demonstrated via modulation of multiple cell signaling events involving critical molecular candidates associated with growth, differentiation, apoptosis, and oncogenesis. Altogether, these preclinical and mechanistic findings strongly implicate the use of diosgenin as a novel, multitarget-based chemopreventive or therapeutic agent against several cancer types. Future research in this field will help to establish not only whether diosgenin is safe and efficacious as a chemopreventive agent against several human cancers, but also to develop and evaluate standards of evidence for health claims for diosgenin-containing foods as they become increasingly popular and enter the marketplace labeled as functional foods and nutraceuticals.

    The purpose of this study was to evaluate the therapeutic efficacy of the cooking group from the burn survivors' perspective. By incorporating concepts of kitchen skills, energy conservation, and desensitization techniques, the cooking group can assist patients with the functional use of their hands, standing tolerance, return to former vocational activities, and socialization with other patients. A questionnaire was developed based on commonly expressed benefits of cooking group. Areas of interest included decreasing anxiety in the kitchen, distraction from their burns, socializing with other burn survivors, and the physical benefits of participating in the group. The results of this study indicate that participants regard the therapeutic cooking group as a valuable treatment modality that effectively combines functional activities with socialization to decrease burn related anxiety and increase motion in a supportive environment for patients with burns.

    Purpose Prior research has identified unrealistic optimism as a bias that might impair informed consent among patient-subjects in early phase oncology trials. Optimism, however, is not a unitary construct – it can also be defined as a general disposition, or what is called dispositional optimism. We assessed whether dispositional optimism would be related to high expectations for personal therapeutic benefit reported by patient-subjects in these trials but not to the therapeutic misconception. We also assessed how dispositional optimism related to unrealistic optimism. Methods Patient-subjects completed questionnaires designed to measure expectations for therapeutic benefit, dispositional optimism, unrealistic optimism, and the therapeutic misconception. Results Dispositional optimism was significantly associated with higher expectations for personal therapeutic benefit (Spearman r=0.333, poptimism was weakly associated with unrealistic optimism (Spearman r=0.215, p=0.005). In multivariate analysis, both dispositional optimism (p=0.02) and unrealistic optimism (poptimism (p=.0001), but not dispositional optimism, was independently associated with the therapeutic misconception. Conclusion High expectations for therapeutic benefit among patient-subjects in early phase oncology trials should not be assumed to result from misunderstanding of specific information about the trials. Our data reveal that these expectations are associated with either a dispositionally positive outlook on life or biased expectations about specific aspects of trial participation. Not all manifestations of optimism are the same, and different types of optimism likely have different consequences for informed consent in early phase oncology research. PMID:26882017

    Full Text Available Chemotherapy-induced mucositis can limit the effectiveness of cancer therapy and increase the risk of infections. However, no specific therapy for protection against mucositis is currently available. In this study, we investigated the therapeutic effect of PLAG (1-palmitoyl-2-linoleoyl-3-acetyl-rac-glycerol, acetylated diglyceride in 5-fluorouracil (5-FU-induced oral mucositis animal models. Hamsters were administered 5-FU (80 mg/kg intraperitoneally on days 0, 6, and 9. The animals’ cheek pouches were then scratched equally with the tip of an 18-gauge needle on days 1, 2, and 7. PLAG was administered daily at 250 mg/kg/day. PLAG administration significantly reduced 5-FU/scratching–induced mucositis. Dramatic reversal of weight loss in PLAG-treated hamsters with mucositis was observed. Histochemical staining data also revealed newly differentiated epidermis and blood vessels in the cheek pouches of PLAG-treated hamsters, indicative of recovery. Whole blood analyses indicated that PLAG prevents 5-FU–induced excessive neutrophil transmigration to the infection site and eventually stabilizes the number of circulating neutrophils. In a mouse mucositis model, mice with 5-FU–induced disease treated with PLAG exhibited resistance to body-weight loss compared with mice that received 5-FU or 5-FU/scratching alone. PLAG also dramatically reversed mucositis-associated weight loss and inhibited mucositis-induced inflammatory responses in the tongue and serum. These data suggest that PLAG enhances recovery from 5-FU–induced oral mucositis and may therefore be a useful therapeutic agent for treating side effects of chemotherapy, such as mucositis and cachexia.

    Because negative pressure can stimulate vascular proliferation, improve blood circulation and promote osteogenic differentiation of bone marrow stromal cells, we investigated the therapeutic effect of negative pressure on femoral head necrosis (FHN) in a rabbit model. Animals were divided into four groups (n = 60/group): [1] model control, [2] core decompression, [3] negative pressure and [4] normal control groups. Histological investigation revealed that at 4 and 8 weeks postoperatively, improvements were observed in trabecular bone shape, empty lacunae and numbers of bone marrow hematopoietic cells and fat cells in the negative pressure group compared to the core decompression group. At week 8, there were no significant differences between the negative pressure and normal control groups. Immunohistochemistry staining revealed higher expression of vascular endothelial growth factor (VEGF) and bone morphogenetic protein-2 (BMP-2) in the femoral heads in the negative pressure group compared with the core decompression group. Transmission electron microscopy revealed that cell organelles were further developed in the negative pressure group compared with the core decompression group. Microvascular ink staining revealed an increased number of bone marrow ink-stained blood vessels, a thicker vascular lumen and increased microvascular density in the negative pressure group relative to the core decompression group. Real-time polymerase chain reaction revealed that expression levels of both VEGF and BMP-2 were higher in the negative pressure group compared with the core decompression group. In summary, negative pressure has a therapeutic effect on FHN. This effect is superior to core decompression, indicating that negative pressure is a potentially valuable method for treating early FHN.

    Lithium is a mood stabiliser used in the treatment of acute mania, bipolar disorder and as augmentation for unipolar major depression. Tremor is a common adverse effect associated with lithium at both therapeutic and toxic serum levels. We present a case of dose-dependent changes in the quality and intensity of a stroke-related, chronic cerebellar tremor with lithium treatment at serum levels within the therapeutic range. On admission, the patient in this case had a baseline fine, postural tremor, which increased in frequency and evolved to include myoclonic jerks once lithium therapy was initiated. Although the patient's serum lithium level was never in the toxic range, his tremor returned to baseline on reduction of his serum lithium level. This case highlights that a pre-existing, baseline tremor may lower the threshold for developing myoclonus. It also suggests that caution may be warranted with lithium therapy in the setting of known cerebellar disease. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    Targeted therapies of malignancies currently consist of therapeutic monoclonal antibodies and small molecule kinase inhibitors. The combination of these novel agents raises the issue of potential antagonisms. We evaluated the potential effect of 4 kinase inhibitors, including the Bruton tyrosine kinase inhibitor ibrutinib, and 3 PI3K inhibitors idelalisib, NVP-BEZ235 and LY294002, on the effects of the 3 monoclonal antibodies, rituximab and obinutuzumab (directed against CD20) and trastuzumab (directed against HER2). We found that ibrutinib potently inhibits antibody-dependent cell-mediated cytotoxicity exerted by all antibodies, with a 50% inhibitory concentration of 0.2 microM for trastuzumab, 0.5 microM for rituximab and 2 microM for obinutuzumab, suggesting a lesser effect in combination with obinutuzumab than with rituximab. The 4 kinase inhibitors were found to inhibit phagocytosis by fresh human neutrophils, as well as antibody-dependent cellular phagocytosis induced by the 3 antibodies. Conversely co-administration of ibrutinib with rituximab, obinutuzumab or trastuzumab did not demonstrate any inhibitory effect of ibrutinib in vivo in murine xenograft models. In conclusion, some kinase inhibitors, in particular, ibrutinib, are likely to exert inhibitory effects on innate immune cells. However, these effects do not compromise the antitumor activity of monoclonal antibodies in vivo in the models that were evaluated.

    Horticulture therapy employs plants and gardening activities in therapeutic and rehabilitation activities and could be utilized to improve the quality of life of the worldwide aging population, possibly reducing costs for long-term, assisted living and dementia unit residents. Preliminary studies have reported the benefits of horticultural therapy and garden settings in reduction of pain, improvement in attention, lessening of stress, modulation of agitation, lowering of as needed medications, antipsychotics and reduction of falls. This is especially relevant for both the United States and the Republic of Korea since aging is occurring at an unprecedented rate, with Korea experiencing some of the world's greatest increases in elderly populations. In support of the role of nature as a therapeutic modality in geriatrics, most of the existing studies of garden settings have utilized views of nature or indoor plants with sparse studies employing therapeutic gardens and rehabilitation greenhouses. With few controlled clinical trials demonstrating the positive or negative effects of the use of garden settings for the rehabilitation of the aging populations, a more vigorous quantitative analysis of the benefits is long overdue. This literature review presents the data supporting future studies of the effects of natural settings for the long term care and rehabilitation of the elderly having the medical and mental health problems frequently occurring with aging.

    Full Text Available The association of pain and endometriosis was recognized with the first definitive published reports of this disorder. Unfortunately, the precise etiologies and pathways leading to nociception and pain symptoms in endometriosis remain poorly understood, and as a result, effective therapeutic interventions are lacking with consequent profound effects on affected women’s quality of life. In this opinion paper we summarize selected proceedings presented at the 28th Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE in Istanbul, Turkey, and review the clinical and translational evidence of chronic pain, neurogenesis, and the pernicious impact of dyspareunia on women with symptomatic endometriosis. The effectiveness of medical treatments is critically assessed and the findings indicate that good therapeutic options are available with extant medications effective in some sub-groups of women with endometriosis, many of which are affordable globally. Nevertheless, new management strategies and drugs need to be developed to increase the options of all afflicted women to minimize and ideally eradicate painful symptoms of endometriosis. However, only by elucidating distinctions among sub-groups with specific symptoms, suggesting different mechanisms, are we likely to derive truly successful therapeutic strategies.

    DT-13 is an isolated compound from Dwarf lillytruf tuber and currently among active research drugs by National Natural Science foundation of China for its several potential effects. The drug has been reported for its multiple pharmacological actions however no thorough review studies are available on it. Our present study is highlighting the pros and cons of DT-13 focusing on its potential pharmacological actions, therapeutic utilization and further exploration for novel targets. The drug possesses very low toxicity profile, quick onset and long duration of action with slow elimination that combinely makes it favorable for the clinical studies. In vivo and in vitro studies show that the drug regulates multiple cellular functions for its several pharmacological effects including, anti-adhesive effects via regulation of tissue factor and transforming growth factor; anti-migratory effects through indirect regulation of NM-IIA in the tumor microenvironment, Tissue factor, down-regulation of CCR5-CCL5 axis and MMP-2/9 inhibition; anti-metastatic effects via regulation of MMPs and tissue factor; pro-apoptotic effects by modulation of endocytosis of EGF receptor; anti-angiogenic effects via regulation of HIF-1α,ERK, Akt signalling and autophagy inducing characteristics by regulating PI3K/Akt/mTOR signalling pathway. In addition to anti-tumor activities, DT-13 has significant anti-inflammatory, cardioprotective, hepatoprotective and immunomodulating effects. Pharmaceutical dosage form and targeted drug delivery system for DT-13 has not been established yet. Moreover, DT-13, has not been studied for its action on brain, colorectal, hepatic, pancreatic, prostate and blood cancers. Similarly the effects of drug on carbohydrate and glucose metabolism is another niche yet to be explored. In some traditional therapies, crude drug from the plant is used against diabetic and neurological disorders that are not reported in scientific literature, however due to profound effects of

    The semi-quantitative method of bone scintigraphy [bone to soft tissue (B/ST) ratio] has been used in diagnosing and evaluating systemic metabolic bone diseases. The aim of this study is to evaluate of the therapeutic effect of secondary hyperparathyroidism (SHP). The subjects were ten hemodialysis patients with SHP. Seven patients underwent parathyroidectomy (PTX), and 22-Oxacalcitoriol (derivative of 1, 25-dihydroxyvitamin D 3 ) (OCT) was given to three patients. Bone scintigraphy and blood tests [intact parathyroid hormone (PTH), alkaline phosphatase (ALP), calcium (Ca), phosphorus (P), bone alkaline phosphatase (BALP), and deoxypridinoline (DPYD)] were performed before and after treatment. Regions of interest were drown around cranium, lumbar vertebrae, femoral neck and soft tissue of left medial thigh to calculate the B/ST ratio. The B/ST ratios of cranium, lumbar vertebrae, and femoral neck were reduced significantly after PTX (cranium, p=0.0079, lumbar vertebrae, p=0.0282, femoral neck, p=0.0252). Intact PTH, ALP, Ca, P, BALP and DPYD levels were reduced significantly after PTX (intact PTH, p=0.003, Ca, p=0.0005, P, p=0.0393, ALP, p=0.005 1, DPYD, p=0.0232, BALP, p=0.0324). After OCT administration, the B/ST ratio of each bony region showed tendency to diminish, although not significantly. Intact PTH levels were reduced significantly, although ALP, BALP, and DPYD levels were not. Ca and P levels were increased significantly because of the medicinal action of OCT. The B/ST ratio of cranium may be non-invasive method and have potential in evaluating the therapeutic effect of SHP. (author)

    Spinal and muscle flexibility have been studied intensively and used clinically as outcome measurements in the rehabilitation of subjects with low back pain. The results of previous studies are contradictory and there is a lack of longitudinal data on the effects of long term therapeutic exercise on flexibility. A controlled experimental study was conducted to determine the effects of progressive therapeutic exercise on spinal and muscle flexibility. Eighty-six chronic low back pain subjects fulfilled the inclusion criteria and were divided into three study groups: (1) intensive training group, (2) home exercise group and (3) control group. The intervention period lasted three months and measurements were performed at both the beginning of the study and immediately after intervention. Follow-up measurements were carried out six and 12 months after baseline. Spinal flexibility was measured with lumbar flexion, extension, spinal lateral flexion and rotation, and muscle flexibility was measured with measurements of erector spinae, hamstring and iliopsoas muscles. Also self-reported outcomes of the Oswestry Index and Borg Scale--Back Pain Intensity were used. Associations between change (pre- to post-treatment) were determined for the dependent variables. The results showed no correlation between flexibility, the Oswestry Index or back pain intensity. After the first three-month period lumbar flexion, extension and spinal rotation decreased among all subjects. Spinal rotation and erector spinae muscle flexibility improved significantly with intensive training. At the nine-month follow-up, erector spine flexibility was still greater than at baseline. Hamstring flexibility increased among the intensive training and home exercise groups from pre- to post-intervention. However, the degree of hamstring flexibility gained during training was subsequently lost following the period without programmed exercise in both training groups. Self-reported outcome variables showed

    Mastitis is considered the most significant and persistent disease in dairy cows, bringing about large economic losses. Subclinical mastitis brings about major cost implications, for it is difficult to detect due to absence of any visible indications and can persist in the mammary tissue throughout lactation. Immunomodulators have been widely used to reduce intramammary infections by modulating bovine mammary gland. Atractylodis macrocephalae Koidz. polysaccharides (RAMP), extracted from herbal medicine, has been used widely especially for its immunomodulatory function for many years. The objective of this study was to estimate an oil emulsified Atractylodis macrocephalae Koidz. polysaccharides (RAMP-O) as a potential therapeutic agent to treat subclinical mastitis by subcutaneous injection of RAMP-O in the area of supramammary lymph node in lactating cows via analysis of SCC, IMIs and NAGase. Injection of RAMP-O in the area of supramammary lymph node significantly reduced milk SCC and NAGase activity compared with control. The quarters with bacterial infection were also progressively reduced in RAMP-O treated cows and only 9 quarters were found to have bacterial infection, while no obvious change was found in the control group. Subcutaneous injection of RAMP-O in the area of supramammary lymph node had therapeutic value in the treatment of bovine subclinical mastitis by reducing SCC, NAGase and IMIs in milk. Considering both the therapeutic effect and the cost of RAMP-O, 32 mg per dose was found most suitable to reduce milk SCC and NAGase. Therefore, RAMP-O deserves further study for its use in treatment of bovine mastitis.

    Short nucleic acid oligomers have found a wide range of applications in experimental physics, biology and medicine, and show potential for the treatment of acquired and genetic diseases. These applications rely heavily on the predictability of hybridization through Watson-Crick base pairing to allow positioning on a nanometer scale, as well as binding to the target transcripts, but also off-target binding to transcripts with partial homology. These effects are of particular importance in the development of therapeutic oligonucleotides, where off-target effects caused by the binding of mismatched sequences need to be avoided. We employ a novel method of probing DNA hybridization using optically active DNA-stabilized silver clusters (Ag-DNA) to measure binding efficiencies through a change in fluorescence intensity. In this way we can determine their location-specific sensitivity to individual mismatches in the sequence. The results reveal a strong dependence of the hybridization on the location of the mismatch, whereby mismatches close to the edges and center show a relatively minor impact. In parallel, we propose a simple model for calculating the annealing ratios of mismatched DNA sequences, which supports our experimental results. The primary result shown in this work is a demonstration of a novel technique to measure DNA hybridization using fluorescent Ag-DNA. With this technique, we investigated the effect of mismatches on the hybridization efficiency, and found a significant dependence on the location of individual mismatches. These effects are strongly influenced by the length of the used oligonucleotides. The novel probe method based on fluorescent Ag-DNA functions as a reliable tool in measuring this behavior. As a secondary result, we formulated a simple model that is consistent with the experimental data.

    To investigate the short-term therapeutic effect of percutaneous vertebroplasty (PVP) for intravertebral cleft (IVC) and to analyze possible outcome predictors. After retrospective review of spot radiographs during PVP, 23 patients were included in this study. Age, sex, symptom duration, functional status, injected cement volume, and type of approach were evaluated using patients' medical and operative records. The following factors were analyzed on radiographs, MRI, dual bone densitometry, spot radiographs during PVP, and CT: anatomical location of the fracture, bone mineral density, morphology of the fracture, IVC morphology, presence of surrounding non-enhanced area and bone marrow edema, degeneration of adjacent discs, co-existing old compression fractures, patterns of cement opacification, pre-procedural kyphosis, and post-procedural kyphosis correction. Effectiveness was defined as a much-improved state or no pain after 1 week, 1 month, and 2 months. Statistical analyses were conducted to evaluate the relationship between those factors and therapeutic outcome using Fisher's exact test, Chi-squared test, and the Mann-Whitney U test. Percutaneous vertebroplasty of IVC was effective in 16 out of 23 (69.6%) patients after 1 week and 1 month and 15 out of 23 (65.2%) patients after 2 months. Post-procedural kyphosis correction {>=}5 and poor functional status (full dependency) were more common in the ineffective group after 1 week and 2 months respectively (P = 0.047, P = 0.02). Kyphotic correction {>=}5 was related to pre-procedural kyphosis {>=}15 (P = 0.018). Functional status was related to subsequent fracture (P = 0.005). Other factors were not statistically significant (P > 0.05). Percutaneous vertebroplasty on osteoporotic vertebral compression fractures (VCF) with IVC was effective in only about 69.6% of patients after the first week and month and in 65.2% of patients after 2 months.

    The sacroiliac joint is a widely described source of low back pain. Therapeutic approaches to relieve pain include the application of pelvic belts. However, the effects of pelvic belts on sacroiliac joint ligaments as potential pain generators are mostly unknown. The aim of our study was to analyze the influence of pelvic belts on ligament load by means of a computer model. Experimental computer study using a finite element method. A computer model of the human pelvis was created, comprising bones, ligaments, and cartilage. Detailed geometries, material properties of ligaments, and in-vivo pressure distribution patterns of a pelvic belt were implemented. The effects of pelvic belts on ligament strain were computed in the double-leg stance. Pelvic belts increase sacroiliac joint motion around the sagittal axis but decrease motion around the transverse axis. With pelvic belt application, most of the strained sacroiliac joint ligaments were relieved, especially the sacrospinous, sacrotuberous, and the interosseous sacroiliac ligaments. Sacroiliac joint motion and ligament strains were minute. These results agree with validation data from other studies. Assigning homogenous and linear material properties and excluding muscle forces are clear simplifications of the complex reality. Pelvic belts alter sacroiliac joint motion and provide partial relief of ligament strain that is subjectively marked, although minimal in absolute terms. These findings confirm theories that besides being mechanical stabilizers, the sacroiliac joint ligaments are likely involved in neuromuscular feedback mechanisms. The results from our computer model help with unraveling the therapeutic mechanisms of pelvic belts.

    The therapeutic effect of bee pollens on acute radiation sickness were evaluated by observing the changes in the peripheral white blood cell (PWBC) count, the total activity of superoxide dismutase (SOD) and the levels of lipid peroxides (LPO) in sera of the irradiated rats following P.O. administration of bee pollens. It was found that bee pollens could remarkably help irradiated rats recover from radiation-induced injury. The functions of bee pollens might be summarized as follows: (1) Stimulating Proliferation of PWBC. The PWBC count of the bee pollens group showed no significant difference as compared with the normal control group on the 30 th day postirradiation. (2) Enhancing antioxidative effect of clearing free radicals. The total activity of serum SOD in the bee pollens group increased by 6.48% as compared with the normal control group on the 30 th day after irradiation, and the LPO levels i.e. MDA and POV in sera of the irradiated rats decreased by 54.73% and 21.60% respectively. The result suggests that using bee pollens as antiradiation and health-promoting agents in clinical treatment of acute radiation sickness and during radiotherapy of patients with tumors may has certain practical value.

    This qualitative empirical study explores the ritual use of ayahuasca in the treatment of addictions. Ayahuasca is an Amazonian psychedelic plant compound created from an admixture of the vine Banisteriopsis caapi and the bush Psychotria viridis. The study included interviews with 13 therapists who apply ayahuasca professionally in the treatment of addictions (four indigenous healers and nine Western mental health professionals with university degrees), two expert researchers, and 14 individuals who had undergone ayahuasca-assisted therapy for addictions in diverse contexts in South America. The study provides empirically based hypotheses on therapeutic mechanisms of ayahuasca in substance dependence treatment. Findings indicate that ayahuasca can serve as a valuable therapeutic tool that, in carefully structured settings, can catalyze neurobiological and psychological processes that support recovery from substance dependencies and the prevention of relapse. Treatment outcomes, however, can be influenced by a number of variables that are explained in this study. In addition, issues related to ritual transfer and strategies for minimizing undesired side-effects are discussed.

    Sea cucumbers belong to the Class Holothuroidea of marine invertebrates. They are commercially valuable and prized as a food and folk medicine in Asia. Nutritionally, sea cucumbers have an impressive profile of valuable nutrients such as vitamins, minerals and amino acids. A number of unique biological and pharmacological activities/properties, including anticancer, anticoagulant/antithrombotic, antimicrobial, antioxidant, antihyperlipidemic, antihyperglycemic, anti-inflammatory, antihypertension and radioprotective, have been ascribed to various compounds isolated from sea cucumbers. The therapeutic properties and medicinal benefits of sea cucumbers can be linked to the presence of a wide array of bioactives, especially triterpene glycosides, acid mucopolysaccharide, sphingoid bases, glycolipids, fucosylated chondroitin sulfate, polysaccharides, phospholipids, cerebrosides, phosphatidylcholines, and other extracts and hydrolysates. This review highlights the valuable bioactive components as well as the multiple therapeutic properties of sea cucumbers with a view to exploring their potential uses as functional foods and a natural source of new multifunctional drugs.

    Proportional positive airway pressure (PPAP) was designed to optimize airway pressure for the therapy of obstructive sleep apnoea (OSA). In a randomized crossover prospective study, the clinical feasibility of PPAP and its immediate effects on the breathing disorder and sleep in comparison with continuous positive airway pressure (CPAP) was evaluated. Twelve patients requiring CPAP therapy underwent CPAP and PPAP titration in a random order. Obstructive and mixed respiratory events could be completely abolished with both forms of treatment. This efficacy could be achieved at a significantly lower mean mask pressure during PPAP titration (8.45+/-2.42 cmH2O) compared to CPAP (9.96+/-2.7 cmH2O) (p=0.002). The mean minimal arterial oxygen saturation (Sa,O2) (82.8+/-6.5%) on the diagnostic night increased significantly (pPPAP titration. Total sleep time, slow wave sleep and rapid eye movement (REM) sleep increased significantly by the same amount during both CPAP and PPAP titration (pPPAP titration night, four patients did not have a preference, and two patients preferred CPAP. The present data show that proportional positive airway pressure is as effective as continuous positive airway pressure in eliminating obstructive events and has the same immediate effect on sleep. The lower average mask pressure during proportional positive airway pressure implies potential advantages compared to continuous positive airway pressure. Proportional positive airway pressure presents a new effective therapeutic approach to obstructive sleep apnoea.

    Full Text Available The present review paper supports the approach to deliver melatonin and to target melatonin receptors for neuroprotection in stroke. We discuss laboratory evidence demonstrating neuroprotective effects of exogenous melatonin treatment and transplantation of melatonin-secreting cells in stroke. In addition, we describe a novel mechanism of action underlying the therapeutic benefits of stem cell therapy in stroke, implicating the role of melatonin receptors. As we envision the clinical entry of melatonin-based therapeutics, we discuss translational experiments that warrant consideration to reveal an optimal melatonin treatment strategy that is safe and effective for human application.

    The aim of this study was to determine the effectiveness of a multimodal treatment in the short and medium term for disability in nonspecific chronic neck pain. The design of this study is a single-blinded randomized controlled trial carried out in a university research laboratory. Forty-five patients between 18 and 65 yrs with nonspecific chronic neck pain were included in this study. Each patient was treated eight times over a 4-wk period. The sample was divided into three groups: control group, subjected to a protocol of manual therapy; experimental group 1, subjected to a protocol of manual therapy and therapeutic patient education; and experimental group 2, subjected to manual therapy, therapeutic patient education, and a therapeutic exercise protocol. Assessments were performed at baseline and at 4, 8, and 16 wks using the following measurements: the Neck Disability Index, the 11-item Tampa Scale of Kinesiophobia, the Fear Avoidance Beliefs Questionnaire, the Neck Flexor Muscle Endurance Test, and the Visual Analog Fatigue Scale. The nonparametric Kruskal-Wallis test for the Neck Disability Index showed statistically significant differences between baseline outcomes and all follow-up periods (P Kruskal-Wallis test, differences were found for the Visual Analog Fatigue Scale and the Neck Flexor Muscle Endurance Test in the follow-ups at 8 and 16 wks (P < 0.05). Analysis of variance for group × time interaction showed statistically significant changes (Tampa Scale of Kinesiophobia, F = 3.613, P = 0.005; Fear Avoidance Beliefs Questionnaire, F = 2.803, P = 0.022). Minimal detectable changes were obtained in both experimental groups for the 11-item Tampa Scale of Kinesiophobia but not in the control group. Differences between experimental groups and the control group were found in the short and medium term. A multimodal treatment is a good method for reducing disability in patients with nonspecific chronic neck pain in the short and medium term.

    Previously, recombinant human respiratory syncytial virus (RSV) monoclonal antibody Fabs were generated by antigen selection from random combinatorial libraries displayed at the tip of filamentous phage. Two such Fabs, which exhibited high binding affinity for RSV F glycoprotein (a major protective antigen), were evaluated for therapeutic efficacy in infected mice just before or at the time of peak virus replication in the lungs. Fab 19, which neutralized RSV infectivity with high efficiency in tissue culture, was effective therapeutically when delivered directly into the lungs by intranasal instillation under anesthesia. In contrast, RSV Fab 126, which failed to neutralize virus in cell culture, did not exhibit a therapeutic effect under these conditions. The amount of Fab 19 required to effect a 5000- to 12,000-fold reduction in titer of RSV in the lungs within 24 hr was rather small. In four separate experiments, a single instillation of 12.9-50 μg of RSV Fab 19 was sufficient to achieve such a reduction in pulmonary virus in a 25g mouse. The use of Fabs instead of the whole immunoglobulin molecules from which they are derived reduced the protein content of a therapeutic dose. This is important because the protein load that can be delivered effectively into the lungs is limited. The therapeutic effect of a single treatment with Fab 19 was not sustained, so that a rebound in pulmonary virus titer occurred on the 2nd day after treatment. This rebound in pulmonary RSV titer could be prevented by treating infected mice with a single dose of Fab 19 daily for 3 days. These observations suggest that human monoclonal Fabs grown in Escherichia coli may prove useful in the treatment of serious RSV disease as well as diseases caused by other viruses where replication in vivo is limited primarily to the lumenal lining of the respiratory tract.

    This study aimed to assess changes in psychological distress and social participation in adults diagnosed with clinical depression during and after participating in a therapeutic horticulture programme, and to investigate if the changes covaried with levels of group cohesiveness during the intervention. An intervention with a single-group design was repeated with different samples in successive years (pooled n = 46). In each year, five groups of 3-7 participants went through the intervention. Data were collected before, twice during, and immediately after a 12-week therapeutic horticulture programme, as well as at 3-months' follow up. Mental health assessments included the Beck Depression Inventory, the State Subscale of Spielberger State-Trait Anxiety Inventory, the Positive Affect Scale from the Positive and Negative Affect Scale, the Perceived Stress Scale, and the Therapeutic Factors Inventory-Cohesiveness Scale. The analysis of the pooled data confirmed significant beneficial change in all mental health variables during the intervention. Change from baseline in depression severity persisted at 3-months' follow up. Increased social activity after the intervention was reported for 38% of the participants. The groups quickly established strong cohesiveness, and this continued to increase during the intervention. The average level of group cohesiveness correlated positively, but not significantly, with change in all mental health outcome variables. © 2011 The Authors.

    Full Text Available Since the discovery of RNA interference (RNAi, excitement has grown over its potential therapeutic uses. Targeting RNAi pathways provides a powerful tool to change biological processes post-transcriptionally in various health conditions such as cancer or autoimmune diseases. Optimum design of shRNA, siRNA, and miRNA enhances stability and specificity of RNAi-based approaches whereas it has to reduce or prevent undesirable immune responses or off-target effects. Recent advances in understanding pathogenesis of autoimmune diseases have allowed application of these tools in vitro as well as in vivo with some degree of success. Further research on the design and delivery of effectors of RNAi pathway and underlying molecular basis of RNAi would warrant practical use of RNAi-based therapeutics in human applications. This review will focus on the approaches used for current therapeutics and their applications in autoimmune diseases, including rheumatoid arthritis and Sjögren’s syndrome.

    Monoclonal antibody 791T/36, prepared against a tumor-associated 72,000 dalton glycoprotein, reacted with cells from primary and metastatic colorectal carcinomas. I-131 or In-111-labelled antibody localized in xenografts of colorectal carcinomas established from in vitro clonogenic populations. Clinically, with I-131-labelled antibody, 8/11 colonic tumors imaged positively. Imaging was negative in four patients with benign colon disease. 5/11 rectal tumors were positively imaged, but excreted I-131 in the bladder obscured tumors in several studies. In-111-labelled antibody gave superior images and positively imaged primary and metastatic sites in 13/14 patients. Prospectively in the detection of recurrent disease, I-131 or In-111-antibody detected 29/33 separate sites in 24 patients. Seven negative patients remain disease free. There were 3 false positives; overall sensitivity was 88%, with 70% specificity. Specific localization of radiolabel was confirmed immunochemically and by counting radioactivity in resected specimens. Antibody conjugates with methotrexate, vindesine and daunomycin retained drug activity and antibody function, including xenograft localization and conjugates were therapeutically effective against xenografts. 791T/36 antibody has potential for immunodetection of primary and recurrent colorectal carcinoma and for targeting of therapeutic agents

    Full Text Available Abstract Background Mesenchymal stem cells (MSCs are pluripotent stem cells derived from bone marrow with secretory functions of various neurotrophic factors. Stromal cell-derived factor-1α (SDF-1α is also reported as one of chemokines released from MSCs. In this research, the therapeutic effects of MSCs through SDF-1α were explored. 6-hydroxydopamine (6-OHDA, 20 μg was injected into the right striatum of female SD rats with subsequent administration of GFP-labeled MSCs, fibroblasts, (i.v., 1 × 107 cells, respectively or PBS at 2 hours after 6-OHDA injection. All rats were evaluated behaviorally with cylinder test and amphetamine-induced rotation test for 1 month with consequent euthanasia for immunohistochemical evaluations. Additionally, to explore the underlying mechanisms, neuroprotective effects of SDF-1α were explored using 6-OHDA-exposed PC12 cells by using dopamine (DA assay and TdT-mediated dUTP-biotin nick-end labeling (TUNEL staining. Results Rats receiving MSC transplantation significantly ameliorated behaviorally both in cylinder test and amphetamine-induced rotation test compared with the control groups. Correspondingly, rats with MSCs displayed significant preservation in the density of tyrosine hydroxylase (TH-positive fibers in the striatum and the number of TH-positive neurons in the substantia nigra pars compacta (SNc compared to that of control rats. In the in vitro study, SDF-1α treatment increased DA release and suppressed cell death induced by 6-OHDA administration compared with the control groups. Conclusions Consequently, MSC transplantation might exert neuroprotection on 6-OHDA-exposed dopaminergic neurons at least partly through anti-apoptotic effects of SDF-1α. The results demonstrate the potentials of intravenous MSC administration for clinical applications, although further explorations are required.

    2018-05-01

    To evaluate the economic outcomes that arose from the introduction of therapeutic reference pricing (TRP) into Slovenian practice in 2013, based on the first three therapeutic classes, namely proton-pump inhibitors (PPIs), angiotensin-converting-enzyme inhibitors (ACEIs), and lipid-lowering agents (LLAs). National health claims data on prescription medicines from January 2011 to December 2015 were analyzed. Monthly medicine expenditure, medicine consumption, changes in medicine use, and market competition (Herfindahl-Hirschman index) were determined to assess the TRP impact on market dynamics. Interrupted time series analysis was used to assess the TRP cost-saving potential. Medicine expenditure in all three therapeutic classes was decreasing prior to TRP; however, with the TRP introduction, the cost for ACEIs and LLAs fell 25 and 45%, respectively. The costs for PPIs decreased by 10%, but the cost reductions before TRP were greater. After TRP introduction, the downward trend for monthly medicine expenditure was less steep; coefficient changes from -20,798 to -363 for PPIs (p < 0.001), from -18,175 to -4862 for ACEIs (p = 0.001) and from -10,669 to -2761 for LLAs (p = 0.105) were observed. Consumption of any therapeutic class or their market competition were not changed significantly. An increased use of the reference pantoprazole (PPIs) was observed and the market position of ezetimibe was deteriorated significantly after TRP introduction. However, the demand for the references simvastatin (LLAs) and ramipril (ACEIs) did not increase. The Slovenian TRP system was established as an effective cost-containment measure. However, pitfalls arising from a country-specific TRP should be considered when introducing this policy.

  20. Position of lung scintigraphy in emergency diagnosis and therapeutic indications in cases of severe pulmonary embolism

    The position of lung scintigraphy in diagnostic strategy is discussed. This technique appears to afford the key examination in severe pulmonary embolism because of its qualities, which are: - speed of execution, - absolute harmlessness, - diagnostic safety. Taking these points in order: - speed of execution is ensured by the very rapid uptake of I 131-labelled albumin macroaggregates (usable immediately) and the existence of the gamma camera; - harmlessness of the examination by the use of non-allergenic radioactive tracers and doses not significantly restricting the vascular bed still perfused; whichever of the two possible techniques is employed (scanner and gamma camera) the examination can always be practised without getting the patient out of bed, which avoids the risk of clot migration due to movement; - certainty of the result by the fact that in the event of a surgical indication the circulation cut-off image is spectacular and obvious in fact a lung amputation image must be equal to or greater than 50% of the pulmonary field before an operation is decided upon all other images remaining within the scope of a hypocoagulant treatment. A study was carried out in a cardio-vascular surgery department on 28 patients hospitalised with a possible view to embolectomy. Lung scintigraphy allows a quick exploration of the minor circulation. In the special clinical situation of the patients, for whom the advisability of an embolectomy is discussed, the scintigraphic examination provides the key: if normal it eliminates the diagnosis absolutely; if not it reveals without extra risk the spectacular obliterations of the vascular bed on which any therapeutic decision, medical or surgical is based [fr

    Ghrelin is a novel growth hormone-releasing peptide with potential endogenous anti-inflammatory activities ameliorating some pathologic inflammatory conditions. Crohn's disease is a chronic debilitating disease characterized by severe T helper cell (Th)1-driven inflammation of the colon. The aim of this study was to investigate the therapeutic effect of ghrelin in a murine model of colitis. We examined the anti-inflammatory action of ghrelin in the colitis induced by intracolonic administration of trinitrobenzene sulfonic acid. Diverse clinical signs of the disease were evaluated, including weight loss, diarrhea, colitis, and histopathology. We also investigated the mechanisms involved in the potential therapeutic effect of ghrelin, such as inflammatory cytokines and chemokines, Th1-type response, and regulatory factors. Ghrelin ameliorated significantly the clinical and histopathologic severity of the trinitrobenzene sulfonic acid-induced colitis; abrogating body weight loss, diarrhea, and inflammation; and increasing survival. The therapeutic effect was associated with down-regulation of both inflammatory and Th1-driven autoimmune response through the regulation of a wide spectrum of inflammatory mediators. In addition, a partial involvement of interluekin-10/transforming growth factor-beta1-secreting regulatory T cells in this therapeutic effect was demonstrated. Importantly, the ghrelin treatment was therapeutically effective in established colitis and avoided the recurrence of the disease. Our data demonstrate novel anti-inflammatory actions for ghrelin in the gastrointestinal tract, ie, the capacity to deactivate the intestinal inflammatory response and to restore mucosal immune tolerance at multiple levels. Consequently, ghrelin administration represents a novel possible therapeutic approach for the treatment of Crohn's disease and other Th1-mediated inflammatory diseases, such as rheumatoid arthritis and multiple sclerosis.

    Sorafenib is currently the only US Food and Drug Administration (FDA)-approved molecular inhibitor for the systemic therapy of advanced hepatocellular carcinoma (HCC). Aspirin has been studied extensively as an anti-inflammation, cancer preventive and therapeutic agent. However, the potential synergistic therapeutic effects of sorafenib and aspirin on advanced HCC treatment have not been well studied. Drug combination studies and their synergy quantification were performed using the combination index method of Chou-Talalay. The synergistic therapeutic effects of sorafenib and aspirin were evaluated using an orthotopic mouse model of HCC and comprehensive gene profiling analyses were conducted to identify key factors mediating the synergistic therapeutic effects of sorafenib and aspirin. Sorafenib was determined to act synergistically on HCC cells with aspirin in vitro. Using Hep3B and HuH7 HCC cells, it was demonstrated that sorafenib and aspirin acted synergistically to induce apoptosis. Mechanistic studies demonstrated that combining sorafenib and aspirin yielded significant synergistically anti-tumor effects by simultaneously silencing ACSL4 and the induction of GADD45B expression in HCC cells both in vitro and in the orthotopic HCC xenograft mouse model. Importantly, clinical evidence has independently corroborated that survival of HCC patients expressing ACSL4highGADD45Blow was significantly poorer compared to patients with ACSL4lowGADD45Bhigh, thus demonstrating the potential clinical value of combining aspirin and sorafenib for HCC patients expressing ACSL4highGADD45Blow. In conclusion, sorafenib and aspirin provide synergistic therapeutic effects on HCC cells that are achieved through simultaneous silencing of ACSL4 and induction of GADD45B expression. Targeting HCC with ACSL4highGADD45Blow expression with aspirin and sorafenib could provide potential synergistic therapeutic benefits. PMID:28900541

    Cholangiocarcinoma is an uncommon primary malignancy of the biliary tract that is challenging to diagnose and treat effectively due to its relatively silent and late clinical presentation. The present study reports a case of a 60-year-old male with distal extrahepatic cholangiocarcinoma with a 3-week history of painless obstructive jaundice symptoms and subjective weight loss. Imaging revealed an obstructing lesion in the common bile duct, just distal to the entrance of the cystic duct. Pathology revealed moderately differentiated cholangiocarcinoma with two positive proximal resection margins. The two positive resection margins presented a challenge during surgery and points to an urgent need for further studies to better illuminate diagnostic and therapeutic options for patients with similar clinicopathological presentation.

    Prior research has identified unrealistic optimism as a bias that might impair informed consent among patient-subjects in early-phase oncology trials. However, optimism is not a unitary construct; it also can be defined as a general disposition, or what is called dispositional optimism. The authors assessed whether dispositional optimism would be related to high expectations for personal therapeutic benefit reported by patient-subjects in these trials but not to the therapeutic misconception. The authors also assessed how dispositional optimism related to unrealistic optimism. Patient-subjects completed questionnaires designed to measure expectations for therapeutic benefit, dispositional optimism, unrealistic optimism, and the therapeutic misconception. Dispositional optimism was found to be significantly associated with higher expectations for personal therapeutic benefit (Spearman rank correlation coefficient [r], 0.333; Poptimism was found to be weakly associated with unrealistic optimism (Spearman r, 0.215; P = .005). On multivariate analysis, both dispositional optimism (P = .02) and unrealistic optimism (Poptimism (P = .0001), but not dispositional optimism, was found to be independently associated with the therapeutic misconception. High expectations for therapeutic benefit among patient-subjects in early-phase oncology trials should not be assumed to result from misunderstanding of specific information regarding the trials. The data from the current study indicate that these expectations are associated with either a dispositionally positive outlook on life or biased expectations concerning specific aspects of trial participation. Not all manifestations of optimism are the same, and different types of optimism likely have different consequences for informed consent in early-phase oncology research. © 2016 American Cancer Society.

    Increasing resistance to antibiotics makes antimicrobial peptides interesting as novel therapeutics. Here, we report on studies of the peptide NLF20 (NLFRKLTHRLFRRNFGYTLR), corresponding to an epitope of the D helix of heparin cofactor II (HCII), a plasma protein mediating bacterial clearance. Peptide effects were evaluated by a combination of in vitro and in vivo methods, including antibacterial, anti-inflammatory and cytotoxicity assays, fluorescence and electron microscopy, and experimental models of endotoxin shock and Pseudomonas aeruginosa sepsis. The results showed that NLF20 displayed potent antimicrobial effects against the Gram-negative bacteria Escherichia coli and P. aeruginosa, the Gram-positive Bacillus subtilis and Staphylococcus aureus and the fungi Candida albicans and Candida parapsilosis. Importantly, this antimicrobial effect was retained in human blood, particularly for P. aeruginosa. Fluorescence and electron microscopy studies showed that the peptide exerted membrane-breaking effects. In an animal model of P. aeruginosa sepsis, NLF20 reduced bacterial levels, resulting in improved survival. Reduced mortality was also observed in experimental animal models of endotoxin shock, which was paralleled with modulated IFN-γ, IL-10 and coagulation responses. Together, these results indicate that functional epitopes of HCII may have therapeutic potential against bacterial infection. © The Author 2015.

    To investigate the therapeutic effect of gene vaccine encoding chicken collagen type II (CC II) on collagen-induced arthritis (CIA) comprehensively. Three groups (CIA) were given a single intravenous injection of plasmid pcDNA-CCOL2A1 (20 microg/kg, 200 microg/kg, 400 microg/kg) respectively and one group (CIA) was injected 200 microg/kg pcDNA3.1 as a control. The effect of gene vaccine (pcDNA-CCOL2A1) was evaluated according to the arthritis score, radiological and histological examinations. The severity of arthritis of CIA rats which were administered 200 microg/kg pcDNA-CCOL2A1 was significantly reduced from the fifth day. According to the radiological and histological examinations, the articular cartilage as well as subchondral bone trabeculae are similar to those of the normal groups, so the bone and articular cartilage structure were protected after treatment with 200 microg/kg pcDNA-CCOL2A1 with a little synovial hyperplasia. The therapeutic effect of 200 microg/kg pcDNA-CCOL2A1 group has significant difference in comparison with that of the pcDNA3.1 group (P 0.05). The new gene vaccine pcDNA-CCOL2A1 has significant therapeutic effect on CIA rats, and the treatment may therefore be an effective strategy for RA patient clinically.

    Full Text Available Recent studies have indicated that targeting glutathione-S-transferase (GST isoenzymes may be a promising novel strategy to improve the efficacy of conventional chemotherapy in the three most common musculoskeletal tumours: osteosarcoma, Ewing's sarcoma, and rhabdomyosarcoma. By using a panel of 15 drug-sensitive and drug-resistant human osteosarcoma, Ewing's sarcoma, and rhabdomyosarcoma cell lines, the efficay of the GST-targeting agent 6-(7-nitro-2,1,3-benzoxadiazol-4-ylthiohexanol (NBDHEX has been assessed and related to GST isoenzymes expression (namely GSTP1, GSTA1, GSTM1, and MGST. NBDHEX showed a relevant in vitro activity on all cell lines, including the drug-resistant ones and those with higher GSTs levels. The in vitro activity of NBDHEX was mostly related to cytostatic effects, with a less evident apoptotic induction. NBDHEX positively interacted with doxorubicin, vincristine, cisplatin but showed antagonistic effects with methotrexate. In vivo studies confirmed the cytostatic efficay of NBDHEX and its positive interaction with vincristine in Ewing's sarcoma cells, and also indicated a positive effect against the metastatisation of osteosarcoma cells. The whole body of evidence found in this study indicated that targeting GSTs in osteosarcoma, Ewing's sarcoma and rhabdomyosarcoma may be an interesting new therapeutic option, which can be considered for patients who are scarcely responsive to conventional regimens.

    Breast cancer is a heterogeneous disease. Thanks to extensive efforts from research scientists and clinicians, treatment for breast cancer has advanced into the era of targeted medicine. With the use of several well-established biomarkers, such as hormone receptors (HRs) (i.e., estrogen receptor [ER] and progesterone receptor [PgR]) and human epidermal growth factor receptor-2 (HER2), breast cancer patients can be categorized into multiple subgroups with specific targeted treatment strategies. Although therapeutic strategies for HR-positive (HR+) HER2-negative (HER2-) breast cancer and HR-negative (HR-) HER2-positive (HER2+) breast cancer are well-defined, HR+ HER2+ breast cancer is still an overlooked subgroup without tailored therapeutic options. In this review, we have summarized the molecular characteristics, etiology, preclinical tools and therapeutic options for HR+ HER2+ breast cancer. We hope to raise the attention of both the research and the medical community on HR+ HER2+ breast cancer, and to advance patient care for this subtype of disease. Copyright © 2015 Elsevier Ltd.

    2016-02-01

    Among the therapeutic strategies in treatment of resistant depression, the use of sequential prescriptions is discussed here. A number of observations, initially quite isolated and few controlled studies, some large-scale, have been reported, which showed a definite therapeutic effect of certain requirements in sequential treatment of depression. The Sequenced Treatment Alternatives to Relieve Depression Study (STAR*D) is up to now the largest clinical trial exploring treatment strategies in non psychotic resistant depression in real-life conditions with an algorithm of sequential decision. The main conclusions of this study are the following: after two unsuccessful attempts, the chance of remission decreases considerably. A 12-months follow-up showed that the higher the use of the processing steps were high, the more common the relapses were during this period. The pharmacological differences between psychotropic did not cause clinically significant difference. The positive effect of lithium in combination with antidepressants has been known since the work of De Montigny. Antidepressants allow readjustment of physiological sequence involving different monoaminergic systems together. Studies with tricyclic antidepressant-thyroid hormone T3: in depression, decreased norepinephrine at the synaptic receptors believed to cause hypersensitivity of these receptors. Thyroid hormones modulate the activity of adrenergic receptors. There would be a balance of activity between alpha and beta-adrenergic receptors, depending on the bioavailability of thyroid hormones. ECT may in some cases promote pharmacological response in case of previous resistance, or be effective in preventing relapse. Cognitive therapy and antidepressant medications likely have an effect on different types of depression. We can consider the interest of cognitive therapy in a sequential pattern after effective treatment with an antidepressant effect for treatment of residual symptoms, preventing relapses

    Full Text Available China has become one of the leading counties in the world to treat hepatic fibrosis with Chinese patent drugs. The therapeutic effect of traditional Chinese medicine (TCM should be evaluated from the aspects of short-term therapeutic effect, long-term therapeutic effect, and effect of relief of symptoms. This article introduces the results of our exploration of the application of liver stiffness measurement to evaluate therapeutic effect, five-year survival rate to assess long-term therapeutic effect, and a “TCM syndrome scale” to evaluate effect of relief of symptoms, suggesting that the Chinese patent drug Fuzheng Huayu capsules/tablets have a marked clinical effect in the treatment of hepatic fibrosis. It is recommended to use serological diagnostic models, conduct prospective studies with long-term follow-up, and analyze the samples and data accumulated over a long period of time, in order to perfect the methods for evaluating the outcome of hepatic fibrosis.

    The normal pattern of performance on list-learning tasks is to recall more words from the beginning (primacy) and end (recency) of the list. This pattern is also seen in patients with closed head injury, but malingerers tend to recall less words from the beginning of word lists, leading to a suppressed primacy effect. The present study examined this pattern on both learning trials and delayed recall of the Auditory Verbal Learning Test (AVLT) in 34 persons performing with normal effort, 38 naive malingerers, 33 warned malingerers, and 29 head-injured patients. Both malingering groups had lower scores on the primacy portion of the list during learning trials, while normals and head-injured patients had normal serial position curves. During delayed recall, normals and head-injured patients did better than the two malingering groups on middle and recency portions of the list. Findings suggest that the serial position effect during learning trials may be a useful pattern of performance to watch for when suspicious of malingering.

    Like other forms of medicine, including Complementary and Alternative Medicine (CAM), homeopathy elicits expectations in patients. The physician-patient relationship, personal and comprehensive treatment and lack of adverse effects are elements in creating positive expectations. Other elements may be associated with negative expectations. We conducted a systematic literature review on placebo and nocebo effects in acupuncture and homeopathy using Medline. Findings on the psychophysiological and neuromediating mechanisms of the placebo-nocebo phenomenon are reviewed. Studies of these effects reveal how expectations and unconscious conditioning can be measured by imaging and EEG methods. They result in significant, non-specific therapeutic effects, which may confuse the evaluation of the specific therapeutic effects treatment, hampering selection of the simillimum. Directions for future research on non-specific therapeutic effects of homeopathy to improve clinical practice and clinical research are discussed.

    Dengue fever is the most prevalent mosquito-borne viral disease globally with about 100 million cases of acute dengue annually. Severe dengue infection can result in a life-threatening illness. In the absence of either a licensed vaccine or antiviral drug against dengue, therapeutic antibodies that neutralize dengue virus (DENV) may serve as an effective medical countermeasure against severe dengue. However, therapeutic antibodies would need to effectively neutralize all four DENV serotypes. It must not induce antibody-dependent enhancement of DENV infection in monocytes/macrophages through Fc gamma receptor (FcγR)-mediated phagocytosis, which is hypothesized to increase the risk of severe dengue. Here, we review the strategies and technologies that can be adopted to develop antibodies for therapeutic applications. We also discuss the mechanism of antibody neutralization in the cells targeted by DENV that express Fc gamma receptor. These studies have provided significant insight toward the use of therapeutic antibodies as a potentially promising bulwark against dengue.

    Limited effective strategies exist to alleviate or treat disruptive behaviors in people with Alzheimer's disease. Fifty-one residents of a long-term care facility with Alzheimer's disease were randomly assigned to one of three intervention groups. A multiple time series, blinded, experimental design was used to compare the effectiveness of therapeutic touch, simulated therapeutic touch, and usual care on disruptive behavior. Three forms of disruptive behavior comprised the dependent variables: physical aggression, physical nonaggression, and verbal agitation. Physical nonaggressive behaviors decreased significantly in those residents who received therapeutic touch compared with those who received the simulated version and the usual care. No significant differences in physically aggressive and verbally agitated behaviors were observed across the three study groups. The study provided preliminary evidence for the potential for therapeutic touch in dealing with agitated behaviors by people with dementia. Researchers and practitioners must consider a broad array of strategies to deal with these behaviors.

    To evaluate the utility of ultrasonography as a guide of determination of therapeutic modality an dto compare the therapeutic effects of modalities in patients with tuberculous pleural effusion. This study included 47 patients who had multiple septations on ultrasonography. We classified ultrasonographic pattern of pleural effusion into three groups according to pattern of septation : linear(n=6),moderate(n=19), honeycombing(n=22). We also classified therapeutic modalities into three groups : thoracentesis group(n=13), percutaneous catheter drainage group(n=11), intrapleural urokinase instillation group(n=23). We assessed the early and late therapeutic effects of these groups prospectively with follow-up chest radiographs. There was statistically no significant difference in therapeutic effect among the groups that had linear and moderate septa on ultrasonography(p<0.01). In patients with honeycombing septa, the therapeutic effects of catheter group and urokinase group were superior to conservative thoracentesis group(p<0.01). In urokinase group,mean duration of drainage(6.6 days) was significantly shorter than catheter group's(12.4 days) (p<0.01). Pattern of septation on ultrasonography could be an useful factor for determination of the therapeutic modality in patients with tuberculous pleural effusion. Percutaneous catheter drainage with urokinase instillation is a good therapeutic modality with shortened duration of drainage in treatment of pleural effusion with honeycombing septae

    Full Text Available Diabetes mellitus is related to low-grade chronic inflammation and oxidative stress. Bupleurum Polysaccharides (BPs, isolated from Bupleurum smithii var. parvifolium has anti-inflammatory and anti-oxidative properties. However, little is known about its therapeutic effects on diabetes. In this experiment, the effects of BPs on alleviation of diabetes and the underlying mechanisms were investigated. Diabetic mice model was established via successive intraperitoneal injections of streptozotocin (100 mg/kg body weight for two days. Mice with blood glucose levels higher than 16.8mmol/L were selected for experiments. The diabetic mice were orally administered with BPs (30 and 60 mg/kg once a day for 35 days. BPs not only significantly decreased levels of blood glucose, but also increased those of serum insulin and liver glycogen in diabetic mice compared to model mice. Additionally, BPs adminstration improved the insulin expression and suppressed the apoptosis in pancreas of the diabetic mice. Histopathological observations further demonstrated that BPs protected the pancreas and liver from oxidative and inflammatory damages. These results suggest that BPs protect pancreatic β cells and liver hepatocytes and ameliorate diabetes, which is associated with its anti-oxidative and anti-inflammatory properties.

  2. A therapeutic gain model for brachytherapy

    When treating with continuous irradiation the potential therapeutic gain or loss depends on several treatment, normal tissue and tumour variables. There are similarities between equations defining tissue effects with fractionated treatment and brachytherapy. The former is sensitive to dose per fraction (and incomplete repair for short intervals between treatments) and the later is sensitive to dose rate and continuous repair factors. Because of these similarities, for typical tumours and normal tissues, dose per fraction and dose rates generally work in similar directions. As the dose per fraction or dose rate increases the therapeutic gain falls. With continuous irradiation the dose rates effects are determined by Beta cell kill and hence the absolute value of Beta . Minimal sensitivity occurs at very low and very high dose rates. The magnitude of cell kill also depends on the Continuous Repair Factor (g) which is a function of the treatment time and the Repair Half Time (in hours) of the tissues (Repair Half Time T 1/2Ln(2)/h, when h the Repair Constant). An interactive optimising model has been written to predict the therapeutic gain or loss as the parameter values are varied. This model includes the tumour and normal tissue parameters alpha and beta Gy (or individual values), their Repair Half Times, dose rates and overall treatment time. The model is based on the Linear-Quadratic equation and the Total Effect (TE) method of Thames and Hendry although the Extrapolated Response Dose (ERD) method of Barendsen produces the same results. The model is written so that the gain or loss may be seen when treatment is always to normal tissue tolerance doses. The magnitude of the therapeutic loss as the dose rate increases and its sensitivity to changes in normal tissue and tumour parameter values is clearly demonstrated

    Medical therapies have been widely used for premenstrual syndrome (PMS), but in all of them side effects are predominant. Herbal remedies rarely have side effects and people have more tendencies toward them than chemical therapies. In this study the therapeutic effect of Vitex agnus castus on women who had the PMS, in comparison with placebo, were investigated. In this randomized, placebo-controlled, double-blind study, from 134 selected patients 128 women suffered from PMS were evaluated (active 62, placebo 66). All patients answered to a self assessment questionnaire about their headache, anger, irritability, depression, breast fullness and bloating and tympani during the premenstrual period before the study. Forty drops of Vitex agnus extract or matching placebo, administrated for 6 days before menses for 6 consecutive cycles. Patients answered the self-assessment questionnaires after 6 menstrual cycles, again. Each item rated using a visual analogue scale (VAS). The mean age was 30.77 (SD=4.37) years in the active group and 30.89 (SD=4.02) years in the placebo group.Rank of variables had significantly difference in active and placebo group before and after the study (PVitex agnus in comparison with placebo (PVitex agnus can be considered as an effective and well tolerated treatment for the relief of symptoms of mild and moderate PMS.

    Malignant tumors show intense glycolysis and, as a consequence, high lactate production and proton efflux activity. We investigated proton dynamics in osteosarcoma, rhabdomyosarcoma, and chondrosarcoma, and evaluated the effects of esomeprazole as a therapeutic agent interfering with tumor acidic microenvironment. All sarcomas were able to survive in an acidic microenvironment (up to 5.9–6.0 pH) and abundant acidic lysosomes were found in all sarcoma subtypes. V-ATPase, a proton pump that acidifies intracellular compartments and transports protons across the plasma membrane, was detected in all cell types with a histotype-specific expression pattern. Esomeprazole administration interfered with proton compartmentalization in acidic organelles and induced a significant dose-dependent toxicity. Among the different histotypes, rhabdomyosarcoma, expressing the highest levels of V-ATPase and whose lysosomes are most acidic, was mostly susceptible to ESOM treatment. - Highlights: • Osteosarcoma, rhabdomyosarcoma, and chondrosarcoma survive in acidic microenvironment. • At acidic extracellular pH, sarcoma survival is dependent on V-ATPase expression. • Esomeprazole administration induce a significant dose-dependent toxicity.

    Scientific reports had shown that stress is related to numerous pathological changes in the body. These pathological changes can bring about numerous diseases and can significantly cause negative effects in an individual. These include gastric ulcer, liver pathology and neurobehavioral changes. A common pathogenesis in many diseases related to stress involves oxidative damage. Therefore, the administration of antioxidants such as vitamin E is a reasonable therapeutic approach. However, there is conflicting evidence about antioxidant supplementation. The aim of this work was to summarize documented reports on the effects of tocopherol and tocotrienol on various pathological changes induced by stress. This review will reveal the scientific evidence of enteral supplementation of vitamin E in the forms of tocotrienol and tocopherol in animal models of stress. These models mimic the stress endured by critically ill patients in a clinical setting and psychological stress in individuals. Positive outcomes from enteral feeding of vitamin E in reducing the occurrence of stress-induced pathological changes are discussed in this review. These positive findings include their ability to reduced stress-induced gastric ulcers, elevated liver enzymes and improved locomotors activity. Evidences showing tocotrienol and tocopherol effects are not just related to its ability to reduce oxidative stress but also acting on other mechanism are discussed.

    The study shows that cell kinetics effects correlate with the effects of cytostatic drugs in the tumour model investigated here. It should, however, be noted that even genetically related tumour cell types may react differently to the same cytostatic drug, and that the cell kinetics effects, due to the changes in the cell cycle, cannot be predicted but should be followed with a very fast method, e.g. sequential flan fluorescence cytophotometry, for optimal therapeutic results.

    Full text: Graves' disease is being treated with I-131 for more than 40 years in China. Previously the dose of I-131 used to be calculated using the 'Quimby' formula. We have now observed that the dose of I-131 administered to patients is now lower in recent years than the early years. The radioactive iodine uptake by the thyroid gland has also changed significantly over a period of time. In this paper we intend to explore these reasons and to research the relationship between the dose and the effect as well as the main cause of the incidence of the hypothyroidism. The parameters in 'Quimby' formula including I-131 uptake, effective half-life and thyroid weight were analyzed and compared with each year data from 1961 to 1988 and subjected to multiple regression analysis to determine the influence on the calculation of dose in 4465 patients. The therapeutic effects were compared with the data of the clinical follow-up of patients between 1961-1973 and 1978-1988 in 748 patients. The factors which might lead to the hypothyroidism were investigated with the non-condition logistic regression. The I-131 uptake was repeatedly measured within one week in 100 patients to identify the changing pattern of the I-131 uptake and its influence on the administered therapeutic dose. We observed an increase in the value of I-131 uptake. The value of I-131 uptake showed an increase after 1977, as well as a prolongation of effective half-life after 1973. The main reason for these changes being a replacement of the equipment in 1977 (G-M counter tube was replaced by scintillation counter), and the other reason being salt iodization in China in 1973. These two factors resulted in a significant reduction in the administered dose of I-131 during the period 1974-1988 as compared to the previous period 1961-1973; the mean administered doses being 168.35MBq and 330.33MBq respectively. The result of multiple regression analyses suggested that the thyroid weight and the effective half

    Benign prostatic hyperplasia (BPH) is a non-malignant enlargement of the prostate that results in obstructive lower urinary tract symptoms. Plant extracts are frequently used to treat BPH rather than therapeutics that can cause severe side effects. ACTICOA() (Ba0rry Callebaut France, Louviers, France) powder (AP) is a cocoa polyphenolic extract, and we have shown in a previous study that oral treatment with AP prevented prostate hyperplasia. This study investigated whether AP could improve established prostate hyperplasia using the same testosterone propionate (TP)-induced prostate hyperplasia model in rats. Male Wistar-Unilever rats were randomly divided in four groups of 12 rats: one group injected with corn oil and orally treated with the vehicle (negative control) and three groups injected subcutaneously with TP and orally treated with the vehicle (positive control) or AP at 24 (AP24) and 48 (AP48) mg/kg/day. Treatments started 1 week after the start of the induction of prostate hyperplasia and lasted for 2 weeks. The influence of TP and AP on body weights, food and water consumptions, plasma polyphenolic concentration, and serum dihydrotestoterone (DHT) level of rats was examined. At completion of the study, rats were sacrificed, and the prostates were removed, cleaned, and weighed. The prostate size ratio (prostate weight/rat body weight) was then calculated. TP significantly influenced the body weight gain of the rats and their food and water consumptions, while AP reduced significantly these differences in a dose-dependent manner. AP significantly reduced serum DHT level and prostate size ratio in comparison with positive controls also dose-dependently. In conclusion, AP orally administered was effective for reducing established prostate hyperplasia, especially at the dose of 48 mg/kg/day.

    While it has been suggested that loving-kindness meditation (LKM) is an effective practice for promoting positive emotions, the empirical evidence in the literature remains unclear. Here, we provide a systematic review of 24 empirical studies (N = 1759) on LKM with self-reported positive emotions. The effect of LKM on positive emotions was estimated with meta-analysis, and the influence of variations across LKM interventions was further explored with subgroup analysis and meta-regression. The meta-analysis showed that (1) medium effect sizes for LKM interventions on daily positive emotions in both wait-list controlled RCTs and non-RCT studies; and (2) small to large effect sizes for the on-going practice of LKM on immediate positive emotions across different comparisons. Further analysis showed that (1) interventions focused on loving-kindness had medium effect size, but interventions focused on compassion showed small effect sizes; (2) the length of interventions and the time spent on meditation did not influence the effect sizes, but the studies without didactic components in interventions had small effect sizes. A few individual studies reported that the nature of positive emotions and individual differences also influenced the results. In sum, LKM practice and interventions are effective in enhancing positive emotions, but more studies are needed to identify the active components of the interventions, to compare different psychological operations, and to explore the applicability in clinical populations.

    The aim of this review is to identify, critically evaluate, and summarize the laughter literature across a number of fields related to medicine and health care to assess to what extent laughter health-related benefits are currently supported by empirical evidence. A comprehensive laughter literature search was performed. A thorough search of the gray literature was also undertaken. A list of inclusion and exclusion criteria was identified. It was necessary to distinguish between humor and laughter to assess health-related outcomes elicited by laughter only. Thematic analysis was applied to summarize laughter health-related outcomes, relationships, and general robustness. Laughter has shown physiological, psychological, social, spiritual, and quality-of-life benefits. Adverse effects are very limited, and laughter is practically lacking in contraindications. Therapeutic efficacy of laughter is mainly derived from spontaneous laughter (triggered by external stimuli or positive emotions) and self-induced laughter (triggered by oneself at will), both occurring with or without humor. The brain is not able to distinguish between these types; therefore, it is assumed that similar benefits may be achieved with one or the other. Although there is not enough data to demonstrate that laughter is an all-around healing agent, this review concludes that there exists sufficient evidence to suggest that laughter has some positive, quantifiable effects on certain aspects of health. In this era of evidence-based medicine, it would be appropriate for laughter to be used as a complementary/alternative medicine in the prevention and treatment of illnesses, although further well-designed research is warranted.

  15. Avian Diagnostic and Therapeutic Antibodies

    A number of infectious agents have the potential of causing significant clinical symptomology and even death, but dispite this, the number of incidence remain below the level that supports producing a vaccine. Therapeutic antibodies provide a viable treatment option for many of these diseases. We proposed that antibodies derived from West Nile Virus (WNV) immunized geese would be able to treat WNV infection in mammals and potential humans. We demonstrated that WNV specific goose antibodies are indeed successful in treating WNV infection both prophylactically and therapeutically in a golden hamster model. We demonstrated that the goose derived antibodies are non-reactogenic, i.e. do not cause an inflammatory response with multiple exposures in mammals. We also developed both a specific pathogen free facility to house the geese during the antibody production phase and a patent-pending purification process to purify the antibodies to greater than 99% purity. Therefore, the success of these study will allow a cost effective rapidly producible therapeutic toward clinical testing with the necessary infrastructure and processes developed and in place.

    Spontaneous intracerebral hemorrhage (ICH) is one type of the most devastating cerebrovascular diseases worldwide, which causes high morbidity and mortality. However, efficient treatment is still lacking. Stem cell therapy has shown good neuroprotective and neurorestorative effect in ICH and is a promising treatment. In this study, our aim was to review the therapeutic effects, strategies, related mechanisms and safety issues of various types of stem cell for ICH treatment. Numerous studies had demonstrated the therapeutic effects of diverse stem cell types in ICH. The potential mechanisms include tissue repair and replacement, neurotrophy, promotion of neurogenesis and angiogenesis, anti-apoptosis, immunoregulation and anti-inflammation and so forth. The microenvironment of the central nervous system (CNS) can also influence the effects of stem cell therapy. The detailed therapeutic strategies for ICH treatment such as cell type, the number of cells, time window, and the routes of medication delivery, varied greatly among different studies and had not been determined. Moreover, the safety issues of stem cell therapy for ICH should not be ignored. Stem cell therapy showed good therapeutic effect in ICH, making it a promising treatment. However, safety should be carefully evaluated, and more clinical trials are required before stem cell therapy can be extensively applied to clinical use.

    Attention Deficit Hyperactivity Disorder (ADHD) is the most common cause of behavioral and learning problems in childhood. Therapeutic efficiency of nootropil (piracetam) in two different doses has been evaluated in the open control study of 80 children with ADHD, 70 boys and 10 girls, aged 6-11 years, being divided into 3 groups. Two groups received nootropil, as a monotherapy, for a month: 1st group (30 patients)--in the dosage of 70 mg/kg daily and 2nd group (30 patients)--40 mg/kg daily orally. The control group of 20 patients did not receive any treatment. All children were examined twice with one month interval. A procedure of assessment included of structured questionnaire to parents, neurological examination with scored evaluation of subtle signs and psychological testing. Nootropil therapy in ADHD children resulted in the improvement of behavioral characteristics, motor coordination as well as continuous, selective and divided attention. A response rate was 60% in patients received 70 mg/kg of nootropil and 43% for nootropil dosage of 40 mg/kg. The results of the study suggest more considerable positive therapeutic effects of nootropil higher dose on behavioral, motor and attention characteristics in children with ADHD.

    Full Text Available Therapeutic dancing has been advocated as an effective adjunct to conventional physical therapies for people living with Parkinson's disease (PD. This systematic review evaluates studies on the outcomes of different dance genres on mobility and quality of life in PD. We searched databases including CINHAL (1982–2015, Medline (1922–2015, Scopus (1996–2015, Web of Science (2002–2015, Embase (2007–2015, PEDro (1999–2015 and the Cochrane Library (1996–2015. The key words were: Parkinson's disease, Parkinson*, Parkinsonism, dance, dance therapy, dance genres, safety, feasibility, and quality of life. Two independent investigators reviewed the texts. Only randomized controlled trials, quasirandomized controlled trials, and case series studies were included. There was emerging evidence that therapeutic dance can be safe and feasible for people with mild to moderately severe PD, with beneficial effects on walking, freezing of gait, and health related quality of life.

    Full Text Available It is well known that bacteria producing β-lactamases in general show marked inoculum effect in susceptibility testing. The aim of this study is to determine the effect of inoculum size on the susceptibility of β-lactamase positive strains of M. catarrhalis to oral β-lactam and non β-lactam antibiotics. MICs of antibiotics were determined by a twofold microdilution technique with two different inoculum sizes were tested: 5x 105 CFU/ml -standard inoculum and 5 x107 CFU/ml -high inoculum. The highest increase (4-fold was observed with penicillins alone (amoxycillin and ampicillin or combined with inhibitor and ceftibuten, followed by older cephalosporins, erithromycine and chloramphenicol ( 2-fold. Tetracycline did not show a significant increase in MIC when a higher inoculum size was applied. In spite of the increase in MIC with high inoculum all strains were still susceptible to amoxycillin combined with clavulanate. MICs of cephalosporins were also below the resistance breakpoint for most of the strains at the higher inoculum. Based on that, we can conclude that therapeutic implications of the inoculum effect were not significant.These data suggest that high inocula should be used to determine MICs of ampicillin and amoxycillin for M. catarrhalis but that this precaution is unnecessary with the cephalosporins tested or with amoxycillin/clavulanate

    The present study explored the role of the therapeutic relationship and introject during the course of dialectical behavior therapy (DBT; Linehan, 1993) for the treatment of borderline personality disorder. Women meeting DSM-IV criteria for borderline personality disorder (N = 101) were randomized to receive DBT or community treatment by experts. The Structural Analysis of Social Behavior (Benjamin, 1974) was used to measure both the therapeutic relationship and introject. Relative to community treatment by experts, DBT participants reported the development of a more positive introject, including significantly greater self-affirmation, self-love, self-protection, and less self-attack, during the course of treatment and 1-year follow-up. The therapeutic relationship did not have an independent effect on intrapsychic or symptomatic outcome but did interact with treatment. DBT participants who perceived their therapist as affirming and protecting reported less frequent occurrences of nonsuicidal self-injury. The study showed positive intrapsychic change during DBT and emphasized the importance of affirmation and control in the therapeutic relationship. Results are discussed in the context of understanding the mechanisms of change in DBT. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

  1. Therapeutic landscapes and postcolonial theory: a theoretical approach to medical tourism.

    Science.gov (United States)

    Buzinde, Christine N; Yarnal, Careen

    2012-03-01

    This paper draws on two conceptual frameworks, therapeutic landscapes and postcolonial theory, to discuss aspects of medical tourism not addressed in extant literature. Building on the intersection between postcolonial and therapeutic landscapes scholarship, it highlights inequalities related to the production of national therapeutic landscapes located in postcolonial regions as well as their discursive (re)positioning as medical tourism destinations. As a framework, therapeutic landscapes can facilitate an understanding of medical tourism sites as curative spaces which combine modern and alternative forms of medicine with travel and leisure. Postcolonial theory critiques the economic, moral and cultural tensions emerging from the intersection between corporations that provide cheaper and more attractive medical services, and the nations on the periphery struggling to offer high medical standards that may not be accessible to their own local populations. In an effort to enhance scholarship on medical tourism, these conceptual frameworks are offered as points of departure, rather than sites of arrival, through which critical dialog on medical tourism can be sustained and broadened.

    This study examined the temporal relation between therapeutic alliance and outcome in two treatments for bulimia nervosa (BN). Eighty adults with BN symptoms were randomized to 21 sessions of integrative cognitive-affective therapy (ICAT) or enhanced cognitive-behavioral therapy (CBT-E). Bulimic symptoms (i.e., frequency of binge eating and purging) were assessed at each session and posttreatment. Therapeutic alliance (Working Alliance Inventory) was assessed at Sessions 2, 8, 14, and posttreatment. Repeated-measures analyses using linear mixed models with random intercepts were conducted to determine differences in alliance growth by treatment and patient characteristics. Mixed-effects models examined the relation between alliance and symptom improvement. Overall, patients in both treatments reported strong therapeutic alliances. Regardless of treatment, greater therapeutic alliance between (but not within) subjects predicted greater reductions in bulimic behavior; reductions in bulimic behavior also predicted improved alliance. Patients with higher depression, anxiety, or emotion dysregulation had a stronger therapeutic alliance in CBT-E than ICAT, while those with more intimacy problems had greater improvement in therapeutic alliance in ICAT compared to CBT-E. Therapeutic alliance has a unique impact on outcome, independent of the impact of symptom improvement on alliance. Within- and between-subjects effects revealed that changes in alliance over time did not predict symptom improvement, but rather that individuals who had a stronger alliance overall had better bulimic symptom outcomes. These findings indicate that therapeutic alliance is an important predictor of outcome in the treatment of BN. (c) 2015 APA, all rights reserved).

    Full Text Available Background: The utility of ultrasound (US for therapeutic purposes is still in its infancy. Therapeutic US (TUS has been used widely in medical field for urological application, surgical intervention, bone healing, and osteointegration in cancer and healing of full thickness excised skin lesions, and within dentistry as a prediagnostic, diagnostic and therapeutic purpose. The purpose of the paper is to review and determine the efficacy of US as one of the treatment modalities for its role in maxillofacial region to reduce pain and promote soft tissue healing. Materials and Methods: A Medline search included of the international literature published between 1976 and 2011 and was restricted to English language articles, published work of past researchers including in vitro and in vivo studies, recent additions of textbooks on surgical and therapeutic applications of US and, current articles in conference papers and reports accessed from the internet using Google search engine on therapeutic ultrasound. Results: Very few article regarding effect of therapeutic of US for its use of insonation for treatment of patient with pain and soft tissue injury are available. This review article mainly emphasizes the therapeutic utility of US in dentistry for its effectiveness to decrease joint stiffness, reduce pain and muscle spasms and improve muscle mobility. In vivo studies have shown very little clinical effects. Conclusions: Further research is warranted in this clinically important area to make the development of noninvasive, multifunctional ultrasound devices for repair, regeneration and other therapeutic utility a success.

    To evaluate the adherence to the recommendations in clinical practice performed by the Therapeutic Positioning Report (TPR) of the Spanish Agency of Medicines and Sanitary Products about the treatment with oral anticoagulants in patients aged≥75 years old with nonvalvular atrial fibrillation (NVAF) treated in Internal Medicine departments in Spain. Observational, cross-sectional and multicenter study in which 837 patients aged≥75 years old with NVAF, with stable treatment with oral anticoagulants at least 3 months before inclusion, and that had started treatment with oral anticoagulants before the inclusion period were included. Mean age was 83.0±5.0 years old, mean CHADS 2 score 3.2±1.2, mean CHA 2 DS 2 -VASc score 5.0±1.4, and mean HAS-BLED score 2.1±0.9. A percentage of 70.8 of patients were treated with vitamin K antagonists (VKA) and the rest of patients with direct oral anticoagulants (DOACs). A percentage of 65.6 of patients treated with VKA did not follow the recommendations made by the TPR compared with 43.0% of patients treated with DOACs (P<.0001). In the case of VKA, the main reason for being considered as not appropriate according to the TPR was having poor control of anticoagulation and not switching to DOACs, whereas in the case of DOACs, it was not receiving the adequate dose according to the TPR. In a high proportion of anticoagulated elderly patients with NVAF in Spain, the recommendations performed by the TPR are not followed, particularly with VKA, since patients are not switched to DOACs despite time in therapeutic range.

    Nausea is the worst and most prevalent chemotherapy-induced complication experienced by 70-80% of patients despite mediation therapy. Reduction of nausea is one of the most important roles of oncologist nurses. Today, complementary therapies in addition to classic medicine, because of their lower costs, receive much attention. Nonetheless, their safety and effectiveness are not yet proven. The purpose of this research was to investigate the effect of therapeutic touch plan as a complementary therapy on acute nausea in women with breast cancer in 2012-2013 in Isfahan, Iran. A quasi-experimental, single-blind, randomized control trial with three groups (control, placebo and intervention) was performed at the Isfahan Seyedolshohada (AS) Teaching Hospital, Isfahan, in 2012-2013. The intervention was therapeutic touch plan on women with breast cancer, with the three groups receiving the same medicine regimen. Information was recorded by a checklist after infusion of chemotherapy drugs. Data analysis was performed by SPSS, ANOVA and Kruskal-Wallis tests. The ANOVA test showed that the therapeutic touch plan was significantly effective in reducing the duration of nausea compared with the control and placebo groups (P touch plan was significantly effective in delaying the onset of nausea compared with the control and placebo groups (P touch plan is effective in reducing acute chemotherapy-induced nausea; thus, education and implementation of the therapeutic touch plan is proposed for clinical nurses.

  6. Cancer Stem Cell Plasticity Drives Therapeutic Resistance

    2016-01-01

    Full Text Available The connection between epithelial-mesenchymal (E-M plasticity and cancer stem cell (CSC properties has been paradigm-shifting, linking tumor cell invasion and metastasis with therapeutic recurrence. However, despite their importance, the molecular pathways involved in generating invasive, metastatic, and therapy-resistant CSCs remain poorly understood. The enrichment of cells with a mesenchymal/CSC phenotype following therapy has been interpreted in two different ways. The original interpretation posited that therapy kills non-CSCs while sparing pre-existing CSCs. However, evidence is emerging that suggests non-CSCs can be induced into a transient, drug-tolerant, CSC-like state by chemotherapy. The ability to transition between distinct cell states may be as critical for the survival of tumor cells following therapy as it is for metastatic progression. Therefore, inhibition of the pathways that promote E-M and CSC plasticity may suppress tumor recurrence following chemotherapy. Here, we review the emerging appreciation for how plasticity confers therapeutic resistance and tumor recurrence.

  7. Therapeutic effects of Glucagon-Like Peptide-2 on experimental radiation enteritis in rat

    Radiation enteritis in patients treated by abdominal and pelvic radiotherapy is characterized by acute mucosal disruption and chronic intestinal fibrosis. Using a model of localized intestinal irradiation in the rat, we showed remote intestinal dysfunction outside the irradiation field along the whole gut, probably associated with perturbations in the systems regulating intestinal functions. Based on the hypothesis of consequential late effects, acute administration of Glucagon-Like Peptide-2, a growth factor with specific trophic effect on the intestinal mucosa, limited the apparition of both acute and chronic radiation enteritis. This suggests that therapeutic strategies targeting the severity of acute tissue damage may also limit chronic sequelae. The study of GLP-2 effects on epithelial cells in co-culture with either subepithelial myo-fibroblasts or enteric nervous system emphasized the problem of the modelization of complex systems in vitro, and suggested a synergic action from these different actors in vivo.

  8. The Opioid System in Temporal Lobe Epilepsy: Functional Role and Therapeutic Potential

    2017-08-01

    Full Text Available Temporal lobe epilepsy is considered to be one of the most common and severe forms of focal epilepsies. Patients often develop cognitive deficits and emotional blunting along the progression of the disease. The high incidence of resistance to antiepileptic drugs and a frequent lack of admissibility to surgery poses an unmet medical challenge. In the urgent quest of novel treatment strategies, neuropeptides are interesting candidates, however, their therapeutic potential has not yet been exploited. This review focuses on the functional role of the endogenous opioid system with respect to temporal lobe epilepsy, specifically in the hippocampus. The role of dynorphins and kappa opioid receptors (KOPr as modulators of neuronal excitability is well understood: both the reduced release of glutamate as well of postsynaptic hyperpolarization were shown in glutamatergic neurons. In line with this, low levels of dynorphin in humans and mice increase the risk of epilepsy development. The role of enkephalins is not understood so well. On one hand, some agonists of the delta opioid receptors (DOPr display pro-convulsant properties probably through inhibition of GABAergic interneurons. On the other hand, enkephalins play a neuro-protective role under hypoxic or anoxic conditions, most probably through positive effects on mitochondrial function. Despite the supposed absence of endorphins in the hippocampus, exogenous activation of the mu opioid receptors (MOPr induces pro-convulsant effects. Recently-expanded knowledge of the complex ways opioid receptors ligands elicit their effects (including biased agonism, mixed binding, and opioid receptor heteromers, opens up exciting new therapeutic potentials with regards to seizures and epilepsy. Potential adverse side effects of KOPr agonists may be minimized through functional selectivity. Preclinical data suggest a high potential of such compounds to control seizures, with a strong predictive validity toward human

    Full Text Available The design and discovery of novel drug candidates are the initial and most probably the crucial steps in the drug development process. One of the tasks of medicinal chemistry is to produce new molecules that have a desired biological effect. However, even today the search for new pharmaceuticals is a very complicated process that is hard to rationalize. Literature provides many scientific reports on future prospects of design of potentially useful drugs. Many trends have been proposed for the design of new drugs containing different structures (dimers, heterodimers, heteromers, adducts, associates, complexes, biooligomers, dendrimers, dual-, bivalent-, multifunction drugs and codrugs, identical or non-identical twin drugs, mixed or combo drugs, supramolecular particles and various nanoindividuals. Recently much attention has been paid to different strategies of molecular hybridization. In this paper, various molecular combinations were described e.g., drug–drug or drug-non-drug combinations which are expressed in a schematic multi-factor form called a molecular matrix, consisting of four factors: association mode, connection method, and the number of elements and linkers. One of the most popular trends is to create small–small molecule combinations such as different hybrids, codrugs, drug–drug conjugates (DDCs and small-large molecule combinations such as antibody-drug conjugates (ADCs, polymer-drug conjugates (PDCs or different prodrugs and macromolecular therapeutics. A review of the structural possibilities of active framework combinations indicates that a wide range of potentially effective novel-type compounds can be formed. What is particularly important is that new therapeutics can be obtained in fast, efficient, and selective methods using current trends in chemical synthesis and the design of drugs such as the “Lego” concept or rational green approach.

    Chronic inflammation in the intestine is a strong risk factor for colitis-associated colorectal cancer (CAC). Hydroxychloroquine (HCQ) is widely used as an anti-inflammatory drug in the treatment of immune-mediated inflammatory disorders and various tumors. However, little is known regarding the effects of HCQ on colitis-associated tumorigenesis. In this study, mice treated with HCQ showed a significant reduction in early-stage colitis following azoxymethane (AOM)/dextran sodium sulfate (DSS) administration, as well as a remarkable inhibition of colonic tumorigenesis and tumor growth at late stages of CAC. Mechanistically, the therapeutic effects of HCQ were attributed to inhibition of inflammatory responses and production of mutagenic reactive oxygen species (ROS) in immune cells and subsequent promotion of apoptosis and cell cycle arrest in tumor cells. Furthermore, we found that HCQ inhibited the production of inflammatory cytokines and ROS in response to toll-like receptor 4 (TLR4) activation in macrophages. Our data presented herein may help guide the clinical use of HCQ as a prevention and treatment strategy for CAC. Copyright © 2016 Elsevier Inc. All rights reserved.

    Cheyne-Stokes respiration with central sleep apnea (CSR-CSA) is associated with a poor prognosis in patients with heart failure (HF). However, some patients do not respond to continuous positive airway pressure (CPAP), so other therapeutic modalities should be considered, such as bi-level positive airway pressure (PAP), which also assists respiration and might be effective for such patients. The 20 patients with HF because of left ventricular systolic dysfunction were assessed: 8 had ischemic etiology, and all had severe CSA according to the apnea - hypopnea index (AHI) determined by polysomnography. All diagnosed patients underwent repeat polysomnography using CPAP. The AHI improved significantly in 11 (AHI or=15). Bi-level PAP titration significantly improved the AHI in the latter group. Those who were unresponsive to CPAP had significantly lower PaCO(2), higher plasma brain natriuretic peptide (BNP), longer mean duration of CSR and fewer obstructive episodes than CPAP responders. After 6 months of positive airway support with either CPAP (n=9) or bi-level PAP (n=7), BNP levels significantly decreased and left ventricular ejection fraction significantly increased. Bi-level PAP could be an effective alternative for patients with HF and pure CSR-CSA who are unresponsive to CPAP.

    Cadaveric model. To compare the effect of PEEK versus conventional implants on scatter radiation to a simulated tumor bed in the spine SUMMARY OF BACKGROUND DATA.: Given the highly vasculature nature of the spine, it is the most common place for bony metastases. After surgical treatment of a spinal metastasis, adjuvant radiation therapy is typically administered. Radiation dosing is primarily limited by toxicity to the spinal cord. The scatter effect caused by metallic implants decreases the accuracy of dosing and can unintentionally increase the effective dose seen by the spinal cord. This represents a dose-limiting factor for therapeutic radiation postoperatively. A cadaveric thorax specimen was utilized as a metastatic tumor model with two separate three-level spine constructs (one upper thoracic and one lower thoracic). Each construct was examined independently. All four groups compared included identical posterior instrumentation. The anterior constructs consisted of either: an anterior polyether ether ketone (PEEK) cage, an anterior titanium cage, an anterior bone cement cage (polymethyl methacrylate), or a control group with posterior instrumentation alone. Each construct had six thermoluminescent detectors to measure the radiation dose. The mean dose was similar across all constructs and locations. There was more variability in the upper thoracic spine irrespective of the construct type. The PEEK construct had a more uniform dose distribution with a standard deviation of 9.76. The standard deviation of the others constructs was 14.26 for the control group, 19.31 for the titanium cage, and 21.57 for the cement (polymethyl methacrylate) construct. The PEEK inter-body cage resulted in a significantly more uniform distribution of therapeutic radiation in the spine when compared with the other constructs. This may allow for the application of higher effective dosing to the tumor bed for spinal metastases without increasing spinal cord toxicity with either

    Full Text Available While it has been suggested that loving-kindness meditation (LKM is an effective practice for promoting positive emotions, the empirical evidence in the literature remains unclear. Here, we provide a systematic review of 24 empirical studies (N = 1759 on LKM with self-reported positive emotions. The effect of LKM on positive emotions was estimated with meta-analysis, and the influence of variations across LKM interventions was further explored with subgroup analysis and meta-regression. The meta-analysis showed that (1 medium effect sizes for LKM interventions on daily positive emotions in both wait-list controlled RCTs and non-RCT studies; and (2 small to large effect sizes for the on-going practice of LKM on immediate positive emotions across different comparisons. Further analysis showed that (1 interventions focused on loving-kindness had medium effect size, but interventions focused on compassion showed small effect sizes; (2 the length of interventions and the time spent on meditation did not influence the effect sizes, but the studies without didactic components in interventions had small effect sizes. A few individual studies reported that the nature of positive emotions and individual differences also influenced the results. In sum, LKM practice and interventions are effective in enhancing positive emotions, but more studies are needed to identify the active components of the interventions, to compare different psychological operations, and to explore the applicability in clinical populations.

  15. Mechanisms of Plasma Therapeutics

    Graves, David

    2015-09-01

    In this talk, I address research directed towards biomedical applications of atmospheric pressure plasma such as sterilization, surgery, wound healing and anti-cancer therapy. The field has seen remarkable growth in the last 3-5 years, but the mechanisms responsible for the biomedical effects have remained mysterious. It is known that plasmas readily create reactive oxygen species (ROS) and reactive nitrogen species (RNS). ROS and RNS (or RONS), in addition to a suite of other radical and non-radical reactive species, are essential actors in an important sub-field of aerobic biology termed ``redox'' (or oxidation-reduction) biology. It is postulated that cold atmospheric plasma (CAP) can trigger a therapeutic shielding response in tissue in part by creating a time- and space-localized, burst-like form of oxy-nitrosative stress on near-surface exposed cells through the flux of plasma-generated RONS. RONS-exposed surface layers of cells communicate to the deeper levels of tissue via a form of the ``bystander effect,'' similar to responses to other forms of cell stress. In this proposed model of CAP therapeutics, the plasma stimulates a cellular survival mechanism through which aerobic organisms shield themselves from infection and other challenges.

  16. Going positive: The effects of negative and positive advertising on candidate success and voter turnout

    Directory of Open Access Journals (Sweden)

    Liam C Malloy

    2016-01-01

    Full Text Available Given the depth of research on negative advertising in campaigns, scholars have wondered why candidates continue to attack their opponents. We build on this research by considering real-world campaign contexts in which candidates are working in competition with each other and have to react to the decisions of the opposing campaign. Our results suggest that it is never efficacious for candidates to run attack ads, but running positive ads can increase a candidate’s margin of victory. These results are conditioned by two factors: candidates must both stay positive and out-advertise their opponent. Second, the effects of positive advertising are strongest in areas where the candidate is losing or winning by a large margin—areas where they might be tempted to not advertise at all.

The current study was designed to evaluate the beneficial therapeutic effects of ethanolic extracts of Nigella sativa, Zingiber officinale and their mixture in Egyptian HCV patients. Sixty volunteer patients with proven HCV and fifteen age matched healthy subjects were included in this study. Exclusion criteria included patients on interferon alpha (IFN-α) therapy, infection with hepatitis B virus, drug-induced liver diseases, advanced cirrhosis, hepatocellular carcinoma (HCC) or other malignancies, blood picture abnormalities and major severe illness. Liver function enzymes, albumin, total bilirubin, prothrombin time and concentration, international normalized ratio, alpha fetoprotein and viral load were all assessed at baseline and at the end of the study. Ethanolic extracts of Nigella sativa and Zingiber officinale were prepared and formulated into gelatinous capsules, each containing 500 mg of Nigella sativa and/or Zingiber officinale. Clinical response and incidence of adverse drug reactions were assessed initially, periodically, and at the end of the study. Both extracts as well as their mixture significantly ameliorated the altered viral load, alpha fetoprotein, liver function parameters; with more potent effect for the combined therapy. In conclusion, administration of Nigella sativa and/or Zingiber officinale ethanolic extracts to HCV patients exhibited potential therapeutic benefits via decreasing viral load and alleviating the altered liver function, with more potent effect offered by the mixture.

    Animal studies and pathophysiological considerations suggest that therapeutic hypothermia after cardiopulmonary resuscitation is the more effective the earlier it is induced. Therefore this study is sought to examine whether pharmacological facilitated hypothermia by administration of 5'-adenosine monophosphate (AMP) is neuroprotective in a rat model of cardiac arrest (CA) and resuscitation. Sixty-one rats were subjected to CA. After 6 min of ventricular fibrillation advanced cardiac life support was started. After successful return of spontaneous circulation (ROSC, n=40), animals were randomized either to placebo group (n=14) or AMP group (800 mg/kg body weight, n=14). Animals were kept at an ambient temperature of 18°C for 12 h after ROSC and core body temperature was measured using a telemetry temperature probe. Neuronal damage was analyzed by counting Nissl-positive (i.e. viable) neurons and TUNEL-positive (i.e. apoptotic) cells in coronal brain sections 7 days after ROSC. Functional status evaluated on days 1, 3 and 7 after ROSC by a tape removal test. Time until core body temperature dropped to <34.0°C was 31 min [28; 45] in AMP-treated animals and 125 min [90; 180] in the control group (p=0.003). Survival until 7 days after ROSC was comparable in both groups. Also number of Nissl-positive cells (AMP: 1 [1; 7] vs. placebo: 2 [1; 3] per 100 pixel; p=0.66) and TUNEL-positive cells (AMP: 56 [44; 72] vs. placebo: 53 [41; 67] per 100 pixel; p=0.70) did not differ. Neither did AMP affect functional neurological outcome up to 7 days after ROSC. Mean arterial pressure 20 min after ROSC was 49 [45; 55] mmHg in the AMP group in comparison to 91 [83; 95] mmHg in the control group (p<0.001). Although application of AMP reduced the time to reach a core body temperature of <34°C neither survival was improved nor neuronal damage attenuated. Reason for this is probably induction of marked hypotension as an adverse reaction to AMP treatment. Copyright © 2014 Elsevier

    Objective The purpose of the present study was to explore the role of the therapeutic relationship and introject during the course of dialectical behavior therapy (DBT; Linehan, 1993) for the treatment of borderline personality disorder. Method Women meeting DSM-IV criteria for borderline personality disorder (N = 101) were randomized to receive DBT or community treatment by experts. The Structural Analysis of Social Behavior (SASB; Benjamin, 1974) was used to measure both the therapeutic relationship and introject. Results Using hierarchical linear modeling, DBT patients reported the development of a more positive introject including significantly greater self-affirmation, self-love, self-protection, and less self-attack during the course of treatment and one-year follow-up relative to community treatment by experts. The therapeutic relationship did not have an independent effect on intrapsychic or symptomatic outcome but did interact with treatment. DBT patients who perceived their therapist as affirming and protecting reported less frequent occurrences of non-suicidal self-injury. Conclusions The study showed positive intrapsychic change during DBT while emphasizing the importance of affirmation and control in the therapeutic relationship. Results are discussed in the context of understanding the mechanisms of change in DBT. PMID:22061867

  2. Therapeutic drug monitoring in pregnancy.

    Therapeutic drug monitoring (TDM) is commonly recommended to optimize drug dosing regimens of various medications. It has been proposed to guide therapy in pregnant women, in whom physiological changes may lead to altered pharmacokinetics resulting in difficulty in predicting the appropriate drug dosage. Ideally, TDM may play a role in enhancing the effectiveness of treatment while minimizing toxicity of both the mother and fetus. Monitoring of drug levels may also be helpful in assessing adherence to prescribed therapy in selected cases. Limitations exist as therapeutic ranges have only been defined for a limited number of drugs and are based on data obtained in nonpregnant patients. TDM has been suggested for anticonvulsants, antidepressants, and antiretroviral drugs, based on pharmacokinetic studies that have shown reduced drug concentrations. However, there is only relatively limited (and sometimes inconsistent) information regarding the clinical impact of these pharmacokinetic changes during pregnancy and the effect of subsequent dose adjustments. Further studies are required to determine whether implementation of TDM during pregnancy improves outcome and is associated with any benefit beyond that achieved by clinical judgment alone. The cost effectiveness of TDM programs during pregnancy also remains to be examined.

    We investigated a small-molecule modulator of tumor necrosis factor alpha (TNF-alpha), UTL-5g (also referred to as GBL-5g), as a potential chemoprotective agent against cisplatin-induced side effects including nephrotoxicity, hepatotoxicity and hematotoxicity. Pretreatment of UTL-5g i.p. in BDF1 mice reduced the levels of blood urea nitrogen (BUN) and creatinine induced by cisplatin treatment. The levels of both aspartate transaminase (AST) and alanine transaminase (ALT) in these animals were also reduced by UTL-5g. Pretreatment of UTL-5g did not significantly affect the number of white blood cells (WBC) under current experimental conditions, yet it markedly increased blood platelet counts by more than threefold. Therapeutic assessment in SCID mice inoculated with human HCT-15 tumor cells showed that UTL-5g did not attenuate the anti-tumor effect of cisplatin but increased the therapeutic efficacy of cisplatin. The LD50 of UTL-5g was determined to be > 2,000 mg/kg by an acute toxicity study. In summary, our studies showed that 1) UTL-5g significantly reduces nephrotoxicity and hepatotoxicity induced by cisplatin in mice, presumably by lowering the levels of TNF-alpha, 2) UTL-5g markedly increased blood platelet counts in mice and 3) UTL-5g treatment increased the therapeutic efficacy of cisplatin against HCT-15 cells inoculated in SCID mice.

    Patient positioning is a challenging task in BNCT-treatments due to the use of multiple fields and a static horizontal beam construction. Positioning accuracy of 5 mm is required for acceptable dose delivery within appropriate limits of dose uncertainty (up to 10% of point dose in target volume). The aim of this study was to determine if a patient head position creating a clear gap between the beam port and the head would have a significant effect on the doses to the peripheral regions of the head, e.g. to the eyes. The gamma dose rates were measured in a water filled ellipsoidal phantom with an ionisation chamber (IC). Mn activation wires were used to determine the Mn-55(n, γ) reaction rates. Twelve measurement points were chosen in the phantom and two phantom positions were applied. According to this study the 35 mm position change and the resulting gap has an obvious effect on the peripheral doses in BNCT. The Mn activation reaction rates were on the average 80% higher in the deviation position than in the reference position. Increasing depth from the surface inside the phantom diminished the gamma dose difference between the two positions. Scattering environment changes with position displacement and resulting gap causes differences in neutron fluences and gamma doses. (author)

    2017-06-01

    Self-generation of information during memory encoding has large positive effects on subsequent memory for items, but mixed effects on memory for contextual information associated with items. A processing account of generation effects on context memory (Mulligan in Journal of Experimental Psychology: Learning, Memory, and Cognition, 30(4), 838-855, 2004; Mulligan, Lozito, & Rosner in Journal of Experimental Psychology: Learning, Memory, and Cognition, 32(4), 836-846, 2006) proposes that these effects depend on whether the generation task causes any shift in processing of the type of context features for which memory is being tested. Mulligan and colleagues have used this account to predict various negative effects of generation on context memory, but the account also predicts positive generation effects under certain circumstances. The present experiment provided a critical test of the processing account by examining how generation affected memory for auditory rather than visual context. Based on the processing account, we predicted that generation of rhyme words should enhance processing of auditory information associated with the words (i.e., voice gender), whereas generation of antonym words should have no effect. These predictions were confirmed, providing support to the processing account.

    During pregnancy, a progressive increase in serum triglyceride (TG) and cholesterol levels is observed whereas TG levels mostly remain hypertriglyceridemia, pregnancy may cause extremely elevated TG levels leading to potentially life-threatening pancreatitis attacks and chylomicronemia syndrome. The only safe medical treatment option during pregnancy is ω-3 fatty acids, which have moderate TG lowering effects. Therapeutic apheresis could be used as primary treatment approach during pregnancy. We reported the effect of double filtration apheresis in one pregnant women with severe hypertriglyceridemia, therapeutic plasmapheresis and double filtration methods in the other severe hypertriglyceridemic pregnant woman; a 32-year-old pregnant woman (patient 1) with a history of hypertriglyceridemia-induced acute pancreatitis during pregnancy and a 30-year-old pregnant woman with extremely high TG levels (12,000 mg/dl) leading to chylomicronemia syndrome (patient 2). Medical nutrition therapy and ω-3 fatty acids were also provided. Double filtration apheresis (patient 1) and plasmapheresis + double filtration apheresis (patient 2) were used. When we calculated the TG levels before and after therapeutic apheresis, maximum decrease achieved with double filtration apheresis was 46.3 % for patient 1 and 37.3 % for patient 2. However, with plasmapheresis TG level declined by 72 % in patient 2. Plasmapheresis seemed to be more efficient to decrease TG levels. Iron deficiency anemia was the main complication apart from technical difficulties by lipemic obstruction of tubing system. Healthy babies were born. Delivery led to decreases in TG levels. It is concluded that during pregnancy therapeutic apheresis is an effective method to decrease extremely high TG levels and risks of its potentially life-threatening complications.

    Full Text Available Medical therapies have been widely used for premenstrual syndrome (PMS, but in all of them side effects are predominant. Herbal remedies rarely have side effects and people have more tendencies toward them than chemical therapies. In this study the therapeutic effect of Vitexagnuscastus on women who had the PMS, in comparison with placebo, were investigated. In this randomized, placebo-controlled, double-blind study, from134 selected patients 128 women suffered from PMS were evaluated (active 62, placebo 66.All patients answered to a self assessment questionnaire about their headache, anger, irritability, depression, breast fullness and bloating and tympani during the premenstrual period before the study. Forty drops of Vitexagnus extract or matching placebo, administrated for 6 days before mensesfor 6 consecutive cycles. Patients answered the self-assessment questionnaires after 6 menstrual cycles, again. Each item rated using a visual analogue scale (VAS.

    Dual-process theories have suggested that emotion plays a key role in the framing effect in decision-making. However, little is known about the potential impact of a specific positive or negative emotional context on this bias. We investigated this question with adult participants using an emotional priming paradigm. First, participants were presented with positive or negative affective pictures (i.e., pleasant vs. unpleasant photographs). Afterward, participants had to perform a financial decision-making task that was unrelated to the pictures previously presented. The results revealed that the presentation framed in terms of gain or loss no longer affected subjects' decision-making following specific exposure to emotionally pleasant pictures. Interestingly, a positive emotional context did not globally influence risk-taking behavior but specifically decreased the risk propensity in the loss frame. This finding confirmed that a positive emotional context can reduce loss aversion, and it strongly reinforced the dual-process view that the framing effect stems from an affective heuristic belonging to intuitive System 1.

    Sacubitril/valsartan (LCZ696) is a first-in-class angiotensin receptor neprilysin inhibitor (ARNI) indicated to reduce the risk of cardiovascular death and hospitalization for heart failure in patients with chronic heart failure (NYHA class II-IV) and reduced ejection fraction. This study was aimed to evaluate the effect of single oral therapeutic (400 mg) and supratherapeutic (1200 mg) doses of LCZ696 on cardiac repolarization. This randomized double-blind crossover study in healthy male subjects compared the effect of therapeutic and supratherapeutic doses of LCZ696 with placebo and moxifloxacin 400 mg (open-label treatment) as positive control. The primary assessment was mean baseline- and placebo-corrected QTcF (∆∆QTcF; Fridericia correction). Additional assessments included the ∆∆QTcB (Bazett's correction), PR interval, QRS duration, heart rate (HR), LCZ696 pharmacokinetics, pharmacokinetic/pharmacodynamic relationships, and safety. Of the 84 subjects enrolled, 81 completed the study. The maximum upper bound of the two-sided 90 % confidence interval for ∆∆QTcF for LCZ696 400 mg and 1200 mg were <10 ms, and assay sensitivity was confirmed with moxifloxacin. No relevant treatment-emergent changes were observed in any of the ECG-derived parameters with LCZ696 or placebo, and the incidence of adverse events was comparable among the treatment groups. Single therapeutic and supratherapeutic doses of LCZ696 did not affect cardiac repolarization as defined by the E14 ICH guidelines.

    Rheumatoid arthritis is a chronic autoimmune disease of unknown aetiology characterised by chronic inflammation in the joints and subsequent destruction of the cartilage and bone. To propose a new strategy for the treatment of arthritis based on the administration of cortistatin, a newly discovered neuropeptide with anti-inflammatory actions. DBA/1J mice with collagen-induced arthritis were treated with cortistatin after the onset of disease, and the clinical score and joint histopathology were evaluated. Inflammatory response was determined by measuring the levels of various inflammatory mediators (cytokines and chemokines) in joints and serum. T helper cell type 1 (Th1)-mediated autoreactive response was evaluated by determining the proliferative response and cytokine profile of draining lymph node cells stimulated with collagen and by assaying the content of serum autoantibodies. Cortistatin treatment significantly reduced the severity of established collagen-induced arthritis, completely abrogating joint swelling and destruction of cartilage and bone. The therapeutic effect of cortistatin was associated with a striking reduction in the two deleterious components of the disease-that is, the Th1-driven autoimmune and inflammatory responses. Cortistatin downregulated the production of various inflammatory cytokines and chemokines, decreased the antigen-specific Th1-cell expansion, and induced the production of regulatory cytokines, such as interleukin 10 and transforming growth factor beta1. Cortistatin exerted its effects on synovial cells through both somatostatin and ghrelin receptors, showing a higher effect than both peptides protecting against experimental arthritis. This work provides a powerful rationale for the assessment of the efficacy of cortistatin as a novel therapeutic approach to the treatment of rheumatoid arthritis.

    2014-02-01

    Environmental enrichment (EE) increases levels of novelty and complexity, inducing enhanced sensory, cognitive and motor stimulation. In wild-type rodents, EE has been found to have a range of effects, such as enhancing experience-dependent cellular plasticity and cognitive performance, relative to standard-housed controls. Whilst environmental enrichment is of course a relative term, dependent on the nature of control environmental conditions, epidemiological studies suggest that EE has direct clinical relevance to a range of neurological and psychiatric disorders. EE has been demonstrated to induce beneficial effects in animal models of a wide variety of brain disorders. The first evidence of beneficial effects of EE in a genetically targeted animal model was generated using Huntington's disease transgenic mice. Subsequent studies found that EE was also therapeutic in mouse models of Alzheimer's disease, consistent with epidemiological studies of relevant environmental modifiers. EE has also been found to ameliorate behavioural, cellular and molecular deficits in animal models of various neurological and psychiatric disorders, including Parkinson's disease, stroke, traumatic brain injury, epilepsy, multiple sclerosis, depression, schizophrenia and autism spectrum disorders. This review will focus on the effects of EE observed in animal models of neurodegenerative brain diseases, at molecular, cellular and behavioural levels. The proposal that EE may act synergistically with other approaches, such as drug and cell therapies, to facilitate brain repair will be discussed. I will also discuss the therapeutic potential of 'enviromimetics', drugs which mimic or enhance the therapeutic effects of cognitive activity and physical exercise, for both neuroprotection and brain repair. © 2013 British Neuropathological Society.

    Suicide has been the second leading cause of death for 18- to 24-year-olds in the United States since 2011. The stress experienced by undergraduate college students has the potential to increase one's risk for suicide. Resilience theory was used as a theoretical framework to examine the interplay between risk and protective factors. A cross-sectional and correlational design was used to assess the mediating effects of positive thinking and/or social support on suicide resilience in 131 college students 18 to 24 years old who completed an online survey. The study found an indirect effect of self-esteem on suicide resilience through positive thinking and social support indicating that as self-esteem increases, positive thinking and social support also increase, which leads to an increase in resilience. The study also found a direct effect of self-esteem, positive thinking, and social support on suicide resilience. The findings inform the development of tailored interventions to build suicide resilience in college students.

  16. Pharmacokinetics and concentration-effect relationships of therapeutic monoclonal antibodies and fusion proteins.

    Science.gov (United States)

    Ternant, David; Paintaud, Gilles

    2005-09-01

    Although monoclonal antibodies (mAbs) constitute a major advance in therapeutics, their pharmacokinetic (PK) and pharmacodynamic (PD) properties are not fully understood. Saturable mechanisms are thought to occur in distribution and elimination of mAbs, which are protected from degradation by the Brambell's receptor (FcRn). The binding of mAbs to their target antigen explains part of their nonlinear PK and PD properties. The interindividual variability in mAb PK can be explained by several factors, including immune response against the biodrug and differences in the number of antigenic sites. The concentration-effect relationships of mAbs are complex and dependent on their mechanism of action. Interindividual differences in mAb PD can be explained by factors such as genetics and clinical status. PK and concentration-effect studies are necessary to design optimal dosing regimens. Because of their above-mentioned characteristics, the interindividual variability in their dose-response relationships must be studied by PK-PD modelling.

    To compare the difference in the therapeutic effects on ovulation disorder in polycystic ovary syndrome (PCOS) between the combined therapy of electroacupuncture and clomiphene and the single medication of clomiphene and to explore the effect mechanism. A total of 80 patients of PCOS were randomized into an acupuncture plus medication group (40 cases) and a medication group (40 cases). In the medication group, since the 5th day of menstruation or medicine-withdrawal bleeding, clomiphene was prescribed for oral administration, continuously for 5 days. In the acupuncture plus medication group, the medication was the same as the medication group. Additionally, 30 min electroacupuncture (continuous wave, 2 Hz) was applied to Qihai (CV 6), Guanyuan (CV 4), Zigong (EX-CA 1), Dahe (KI 12), Sanyinjiao (SP 6), Zhongji (CV 3), Diji (SP 8), Shenshu (BL 23), Sanjiaoshu (BL 22) and Ciliao (BL 32), etc. The treatment started on the 5th day of menstruation or medicine-withdrawal bleeding, once every two days, 3 times a week. One cycle of menstruation or 1 month was taken as one course. The treatment cycles were 3 months in the two groups. The level of estradiol (E 2 ) and progesterone (P) in the serum, the endometrial thickness and morphology, ovulation rate and clinical pregnancy rate, as well as the clinical therapeutic effects were compared after treatment in the two groups. Two cases were dropped out because the herbal medicine was taken simultaneously in the acupuncture plus medication group. In the medication group, the medication was discontinued in 3 cases due to gastrointestinal adverse reactions. The total effective rate was 86.8% (33/38) in the acupuncture plus medication group, better than 64.9% (24/37) in the medication group ( P medication group was higher than that in the medication group [(86.8%, 33/38) vs (64.9% 24/37), P medication group was higher than the medication group in tendency, without significant difference [21.1% (8/38) vs 16.2% (6/37), P >0

    To investigate whether therapeutic ultrasound (US) use over metallic implants has the potential for adverse effects as a result of greater temperature increases at the tissue-metal interface. A randomized controlled trial. A research laboratory. Sprague-Dawley rats (N=40; weight, 230-300g) were used and divided into 3 study groups. In group 1, both limbs of 10 rats were used for evaluation of temperature changes. Metal pins were placed into the femur of the left limb, and the right limbs were used as controls. A thermal sensor was placed into the medulla to record the elevation of tissue temperature during US application. In groups 2 and 3 with 15 rats in each, a midshaft femoral fracture was produced, and intramedullary fixation was performed with metal pins. Group 2 received US treatment for 5 minutes daily and continued for 27 days. Group 3 served as controls. The rats in groups 2 and 3 were killed on postoperative day 30. The specimens were evaluated by radiology, histopathology, and biomechanics. The presence of metal in bone did not cause an increased temperature rise. US application did not increase or decrease callus formation, and there was no tissue necrosis. The average removal torques of pins in groups did not show a significant difference.

    The goal of the present studies was to examine whether attentional control, a self-regulatory attentional mechanism, mediates the effect of social anxiety on positive affect. We tested this mediation in two studies using undergraduate students selected to represent a broad range of severity of social anxiety. Self-report assessments of social anxiety, attentional control, and positive affect were collected in a cross-sectional design (Study 1) and in a longitudinal design with three assessment points (Study 2). Results of both studies supported the hypothesized mediational model. Specifically, social anxiety was inversely related to attentional control, which itself positively predicted positive affect. This mediation remained significant even when statistically controlling for the effects of depression. Additionally, the hypothesized model provided superior model fit to theoretically-grounded equivalent models in both studies. Implications of these findings for understanding diminished positive affect in social anxiety are discussed. PMID:23254261

    Full Text Available Class IIa bacteriocins have been primarily explored as natural food preservatives, but there is much interest in exploring the application of these peptides as therapeutic antimicrobial agents. Bacteriocins of this class possess antimicrobial activity against several important human pathogens. Therefore, the therapeutic development of these bacteriocins will be reviewed. Biological and chemical modifications to both stabilize and increase the potency of bacteriocins are discussed, as well as the optimization of their production and purification. The suitability of bacteriocins as pharmaceuticals is explored through determinations of cytotoxicity, effects on the natural microbiota, and in vivo efficacy in mouse models. Recent results suggest that class IIa bacteriocins show promise as a class of therapeutic agents.

    Full Text Available The experimental study design on cell cultures allows the direct biological evaluation at the cellular level, of the therapeutic effect that natural factors can play over the organism.Techniques for obtaining cell cultures requires a complex and laborious task that starts from live tissue sampling, continuous with isolation of cells and their preparation for sowing a culture plate. This preparation involves mechanical and enzymatic action from the researcher on biological material. Derived cell cultures are monitored morphologically by high-performance inverted biological microscope, with video camera for image acquisition. In the final stage, the cells are scraped, and through biochemical and molecular techniques, the therapeutic efficiency hypothesis of the investigated natural factor is verified experimentally. The cell cultures can be crioconservated in special containers with liquid nitrogen.

    Full Text Available Abuse of a dominant position is a threat to the functioning of the free market. This is the reason why we have proposed to highlight the impact of this particular anti-competitive practice in the European Union area. The aim of this paper is to present, from a theoretical and practical approach, the implications and the effects of this type of behavior and also to highlight the main actors in this process. In order to achieve these goals, we will use the content analysis to compress the effects of the abuse of dominant position in two categories: positive and negative effects. The historical method to emphasize the historical origins of the concepts and institutions involved. The comparative method will be used to nominate specific features, concepts or institutions that we will analyze and also it will help us to analyze the evolution that have occurred over time in terms of their development and to highlight certain advantages or disadvantages in terms of choice of competition policy on the abuse of a dominant position. In this paper we will notice that both the companies and the market itself are facing with companies that use anti-competitive since 1900. These kind of practices are harmful both for competition and for consumers, so that should not be allowed to expand. In this context, the European Commission imposed a set of rules that all operators must comply in order to protect, maintain and stimulate competition in the Single Market and to promote fair competition.

    Two series of present-day pacemakers were tested in vitro with pulsed x-ray radiation. The first series of 12 pacemakers consisted of 10 different types and models of demand pacemakers (VVI). The second series of 13 pacemakers had 9 different types and models of programmable pacemakers. Unlike the first series which showed only mild changes in frequency and pulse width, all but four of the programmable pacemakers presented sudden complete failure after different radiation doses. We conclude that direct pulse radiation at therapeutic levels of programmable pacemakers should be avoided

    The most common types of non-malignant prostate diseases are benign prostatic hyperplasia (BPH) and chronic prostatitis (CP). The aim of this study was to find out whether thermobalancing therapy with a physiotherapeutic device is effective for BPH and CP. During a 2.5-year period, 124 men with BPH over the age of 55 were investigated. Clinical parameters were tested twice: via the International Prostate Symptom Score (IPSS) and via ultrasound measurement of prostate volume (PV) and uroflowmetry maximum flow rate (Q max ), before and after six months of therapy. In 45 men with CP under the age of 55, the dynamics of the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) were studied. The results of the investigated index tests in men with BPH confirmed a decrease in IPSS ( p BPH and the improvement in NIH-CPSI-QoL in patients with CP after using a physiotherapeutic device for six months as mono-therapy, support the view that thermobalancing therapy with the device can be recommended for these patients. Furthermore, the therapeutic device is free of side effects.

    For the brief systemic therapy (BST), the evaluation of the patient's position towards the care is a prerequisite to psychotherapy. Three positions of the patient are described. The "tourist's" position: the patient claims to have no problem and doesn't suffer. Someone asks him to make an appointment, sometimes with threats. The "complaint's" position: the patient claims to suffer, but attributes the responsibility of this suffering to others. These two positions are not good for beginning a therapy. The "customer's" position differs from both previous positions. The "customer" considers that he has a psychological problem which depends on him and he is motivated in the resolution of it. In theory, the "customer" is more motivated and the therapeutic alliance is better. It is for this reason that the BST estimates the position of the patient at first, to bring the patient to the "customer's" position. The objective of this study is to assess an interview which identifies the patient's position towards the care, and to validate the theoretical elaborations of the brief systemic therapy. The study concerns the follow-up of outpatients who consult a psychiatrist for the first time. The evaluation of the patients checks their position towards care using the Tourist-Complaint-Customer (TCC) inventory, how they suffer, the therapeutic alliance (scale Haq-2) and the compliance during care. The evaluation by the psychiatrists checks the suffering perceived, the motivation perceived and the diagnoses according to the DSM. The typology of these patients is made up of one half "complaint", a quarter of "tourist" and a quarter of "customer". The "customer's" position is correlated with the therapeutic alliance and the motivation perceived by the psychiatrist. The motivation perceived by the psychiatrist is correlated with the therapeutic alliance. These results correspond to the theoretical elaborations of the BST. the TCC inventory provides information on the motivation and

    Autobiographical memories are characterised by a range of emotions and emotional reactions. Recent research has demonstrated that differences in emotional valence (positive vs. negative emotion) and arousal (the degree of emotional intensity) differentially influence the retrieved memory narrative. Although the mnemonic effects of valence and arousal have both been heavily studied, it is currently unclear whether the effects of emotional arousal are equivalent for positive and negative autobiographical events. In the current study, multilevel models were used to examine differential effects of emotional valence and arousal on the richness of autobiographical memory retrieval both between and within subjects. Thirty-four young adults were asked to retrieve personal autobiographical memories associated with popular musical cues and to rate the valence, arousal and richness of these events. The multilevel analyses identified independent influences of valence and intensity upon retrieval characteristics at the within- and between-subject levels. In addition, the within-subject interactions between valence and arousal highlighted differential effects of arousal for positive and negative memories. These findings have important implications for future studies of emotion and memory, highlighting the importance of considering both valence and arousal when examining the role emotion plays in the richness of memory representation.

    Full Text Available In marketing, it is important to see how competitive a university is. Among public universities (PTN and private universities (PTS, it shows a very competitive situation recently. To overcome this problem, it requires shaping up the institution image and trust for increasing the positive word of mouth among students. This study aims to determine the effect of the institution image, trust both partially and simultaneously on the positive word of mouth by the students of private universities in Surabaya with their accreditation levels of A, B and C. The sample consists of students from six colleges with accreditation ratings A, B, and C totaling 125 students. Accidental sampling technique was done using a sampling technique of multiple regression analysis with SPSS version 17. It shows, for the college with accreditation category C, the image of the institution both partially and simulta-neously has significant positive effect on the positive word of mouth. For the college accreditation category B, the image of the institution and trust simultaneously has significant positive effect on the positive word of mouth and, finally, trust in accreditation category A has significant positive effect on the positive word of mouth and the institution image and trust simultaneously have significant positive effect on the positive word of mouth.

Therapeutic interpersonal relationships have the capacity to transform and enrich the patients’ experiences. Consequently, with an increasing necessity to focus on patient-centered care, it is imperative for health care professionals to therapeutically engage with patients to improve health-related outcomes. Studies were identified through an electronic search, using the PubMed, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO databases of peer-reviewed research, limited to the English language with search terms developed to reflect therapeutic interpersonal relationships between health care professionals and patients in the acute care setting. This study found that therapeutic listening, responding to patient emotions and unmet needs, and patient centeredness were key characteristics of strategies for improving therapeutic interpersonal relationships.

  14. Radiobiological speculations on therapeutic total body irradiation

    International Nuclear Information System (INIS)

    Vriesendorp, H.M.

    1990-01-01

    Unexpected total body irradiation (TBI) of human beings, involved in nuclear warfare or in accidents in nuclear reactors can be lethal. In the 1950s, bone marrow transplantation was discovered as a potentially life saving procedure after TBI in the dose range of 5.0 to 12.0 Gy. Since that time, deliberate or therapeutic TBI has been used to condition patients with a lethal bone marrow disorder for bone marrow replacement. The therapeutic ratio of TBI followed by bone marrow transplantation is small. Many potentially lethal complications can occur, such as acute TBI side effects, late TBI side effects or immunological complications of bone marrow transplantation such as graft versus host disease or graft rejection. The benefits of TBI and bone marrow transplantation are that they offer a chance for cure of previously lethal bone marrow disorders. The optimal parameters for TBI remain to be defined. The review discusses the current clinical and experimental animal data, as they relate to the future definition of less toxic TBI procedures with a better therapeutic ratio. Different TBI procedures are required for patients with malignant vs. non-malignant disorders or for patients with histoincompatible vs. histocompatible bone marrow donors.77 references

    Available literature on radiation injury to normal tissue stroma and ablation of epidermoid carcinoma was surveyed. Computer programs (RAD3 and RAD1) were then used to derive cell kinetic parameters and generate iso-effect tables for the relevant tissues. The two tables provide a set of limiting doses for tolerance of normal connective tissue (16% risk of injury) and for ablation of epidermoid cancer (16% risk of recurrence) covering a wide range of treatment schedules. Calculating the ratios of normal tissue tolerance to tumor control doses for each treatment scheme provides an array of therapeutic ratios, from which appropriate treatment schemes can be selected

    Conventional therapies for malignant cancer such as chemotherapy and radiotherapy are associated with poor survival rates owing to the development of cellular resistance to cancer drugs and the lack of targetability, resulting in unwanted adverse effects on healthy cells and necessitating the lowering of therapeutic dose with consequential lower efficacy of the treatment. Gene therapy employing different types of viral and non-viral carriers to transport gene(s) of interest and facilitating production of the desirable therapeutic protein(s) has tremendous prospects in cancer treatments due to the high-level of specificity in therapeutic action of the expressed protein(s) with diminished off-target effects, although cancer cell-specific delivery of transgene(s) still poses some challenges to be addressed. Depending on the potential therapeutic target genes, cancer gene therapy could be categorized into tumor suppressor gene replacement therapy, immune gene therapy and enzyme- or prodrug-based therapy. This review would shed light on the current progress of delivery of potentially therapeutic genes into various cancer cells in vitro and animal models utilizing a variety of viral and non-viral vectors.

    The therapeutic use of cannabis has generated a lot of interest in the past years, leading to a better understanding of its mechanisms of action. Countries like the United States and Canada have modified their laws in order to make cannabinoid use legal in the medical context. It's also the case in France now, where a recent decree was issued, authorizing the prescription of medication containing "therapeutic cannabis" (decree no. 2013-473, June 5, 2013). Cannabinoids such as dronabinol, Sativex and nabilone have been tested for the treatment of acute and chronic pain. These agents are most promising to relieve chronic pain associated with cancer, with human immunodeficiency virus infection and with multiple sclerosis. However, longer-term studies are required to determine potential long-term adverse effects and risks of misuse and addiction.

    2016-01-01

    Full Text Available Parkinson's disease (PD is a common, progressive neurodegenerative disease characterised by degeneration of nigrostriatal dopaminergic neurons, aggregation of α-synuclein and motor symptoms. Current dopamine-replacement strategies provide symptomatic relief, however their effectiveness wear off over time and their prolonged use leads to disabling side-effects in PD patients. There is therefore a critical need to develop new drugs and drug targets to protect dopaminergic neurons and their axons from degeneration in PD. Over recent years, there has been robust evidence generated showing that epigenetic dysregulation occurs in PD patients, and that epigenetic modulation is a promising therapeutic approach for PD. This article first discusses the present evidence implicating global, and dopaminergic neuron-specific, alterations in the methylome in PD, and the therapeutic potential of pharmacologically targeting the methylome. It then focuses on another mechanism of epigenetic regulation, histone acetylation, and describes how the histone acetyltransferase (HAT and histone deacetylase (HDAC enzymes that mediate this process are attractive therapeutic targets for PD. It discusses the use of activators and/or inhibitors of HDACs and HATs in models of PD, and how these approaches for the selective modulation of histone acetylation elicit neuroprotective effects. Finally, it outlines the potential of employing small molecule epigenetic modulators as neuroprotective therapies for PD, and the future research that will be required to determine and realise this therapeutic potential.

    Full Text Available Good positioning statements have an effect on consumer brand awareness. However, the competitive context formed by the novelty of the category and the brand market structure may hinder the assimilation of positioning and its association with the pre-existing image. This study assesses the effectiveness of positioning statements in the generation of brand awareness, considering its competitive context. Using an experimental design, with a group of control, the exposure of brands and their competitive contexts were manipulated and the positioning statement remained constant for a sample of consumers. The results show the positioning statement had an effect on both assimilation of the message and valence of image association, which adds awareness for the brand, but only for the traditional category. The effectiveness on the message assimilation occurred within the weak brand and within the less known median brand. For the image valence, it occurred only between the weak brand and the strong one from the traditional category. These findings are distinct among consumer segments. The research brings up a classic theme, but presents a new methodological approach to measure the effectiveness of brand positioning.

    Bee pollen grains, as the male reproductive part of seed-bearing plants contain considerable concentrations of various phytochemicals and nutrients. Since antiquity, people throughout the world used pollens to cure colds, flu, ulcers, premature aging, anemia and colitis. It is now well-documented that some bee pollen secondary metabolites (e.g. flavonoid) may have positive health effects. In recent years, the flavonoids have attracted much interest because of their wide range of biological properties and their beneficial effects on human health. The current review, points out potential therapeutic effects of bee pollen flavonoids as one of the main bee pollen bioactive compounds in allergic and immunological diseases. Due to the fact that some types of flavonoid components in bee pollen have anti-allergic, anti-oxidant and anti-inflammatory properties, bee pollen flavonoids can be excellent candidates for future studies including phytotherapy, molecular pharmacology and substitutes for chemicals used in treating allergic and immunological disorders.

    Full Text Available Therapeutic interchange of a same class medication for an outpatient medication is a widespread practice during hospitalization in response to limited hospital formularies. However, therapeutic interchange may increase risk of medication errors. The objective was to characterize the prevalence and safety of therapeutic interchange.Secondary analysis of a transitions of care study. We included patients over age 64 admitted to a tertiary care hospital between 2009-2010 with heart failure, pneumonia, or acute coronary syndrome who were taking a medication in any of six commonly-interchanged classes on admission: proton pump inhibitors (PPIs, histamine H2-receptor antagonists (H2 blockers, hydroxymethylglutaryl CoA reductase inhibitors (statins, angiotensin-converting enzyme (ACE inhibitors, angiotensin receptor blockers (ARBs, and inhaled corticosteroids (ICS. There was limited electronic medication reconciliation support available. Main measures were presence and accuracy of therapeutic interchange during hospitalization, and rate of medication reconciliation errors on discharge. We examined charts of 303 patients taking 555 medications at time of admission in the six medication classes of interest. A total of 244 (44.0% of medications were therapeutically interchanged to an approved formulary drug at admission, affecting 64% of the study patients. Among the therapeutically interchanged drugs, we identified 78 (32.0% suspected medication conversion errors. The discharge medication reconciliation error rate was 11.5% among the 244 therapeutically interchanged medications, compared with 4.2% among the 311 unchanged medications (relative risk [RR] 2.75, 95% confidence interval [CI] 1.45-5.19.Therapeutic interchange was prevalent among hospitalized patients in this study and elevates the risk for potential medication errors during and after hospitalization.

    2016-01-01

    Full Text Available Biologics have emerged as a powerful and diverse class of molecular and cell-based therapies that are capable of replacing enzymes, editing genomes, targeting tumors, and more. As this complex array of tools arises a distinct set of challenges is rarely encountered in the development of small molecule therapies. Biotherapeutics tend to be big, bulky, polar molecules comprised of protein and/or nucleic acids. Compared to their small molecule counterparts, they are fragile, labile, and heterogeneous. Their biodistribution is often limited by hydrophobic barriers which often restrict their administration to either intravenous or subcutaneous entry routes. Additionally, their potential for immunogenicity has proven to be a challenge to developing safe and reliably efficacious drugs. Our discussion will emphasize immunogenicity in the context of therapeutic proteins, a well-known class of biologics. We set out to describe what is known and unknown about the mechanisms underlying the interplay between antigenicity and immune response and their effect on the safety, efficacy, pharmacokinetics, and pharmacodynamics of these therapeutic agents.

    Effective recruitment, retention and development of the existing workforce will become increasingly important as cancer incidence increases, patient numbers increase, and challenging targets are set to deliver world class radiotherapy in the UK. This study aimed to explore the experiences of therapy radiographers working at band five and six with specific reference to job satisfaction. The key objectives were: 1.To explore and understand the experiences of Therapeutic Radiographers from graduation to their first senior/supervisory position. 2.To identify the factors that influence perceptions of job satisfaction. 3.To suggest supportive strategies which could lead to increased job satisfaction? Method: A qualitative case study approach using focus groups was adopted to explore the professional experience of therapeutic radiographers in two large departments. Thematic analysis was used to identify categories and themes, which informed the development of a framework that identified factors that influence job satisfaction. Results and discussion: The participants identified diverse but interlinking facets that influence job satisfaction. The core theme was continuous professional development and subthemes were; organisation issues, transition into role, workload and teamwork. Job satisfaction appears to be multifaceted and is dependent on the individual, context of work and the working environment. Conclusion: Significant factors which impact on job satisfaction for band 5–6 therapy radiographers have been identified. It would appear that these could be positively influenced by managers and organisations. Further insight into the professional experiences of therapeutic radiographers is needed with specific reference to preceptorship/mentoring, staff appraisals and career aspirations/expectations. This insight would be valuable to inform future retention and development strategies

    Metallic nanoparticles (MNP) are able to release localized x-rays when activated with a high energy proton beam by the particle-induced x-ray emission (PIXE) effect. The exploitation of this phenomenon in the therapeutic irradiation of tumors has been investigated. PIXE-based x-ray emission directed at CT26 tumor cells in vitro, when administered with either gold (average diameter 2 and 13 nm) or iron (average diameter 14 nm) nanoparticles (GNP or SNP), increased with MNP solution concentration over the range of 0.1-2 mg ml{sup -1}. With irradiation by a 45 MeV proton therapy (PT) beam, higher concentrations had a decreased cell survival fraction. An in vivo study in CT26 mouse tumor models with tumor regression assay demonstrated significant tumor dose enhancement, thought to be a result of the PIXE effect when compared to conventional PT without MNP (radiation-only group) using a 45 MeV proton beam (p < 0.02). Those receiving GNP or SNP injection doses of 300 mg kg{sup -1} body weight before proton beam therapy demonstrated 90% or 75% tumor volume reduction (TVR) in 20 days post-PT while the radiation-only group showed only 18% TVR and re-growth of tumor volume after 20 days. Higher complete tumor regression (CTR) was observed in 14-24 days after a single treatment of PT with an average rate of 33-65% for those receiving MNP compared with 25% for the radiation-only group. A lower bound of therapeutic effective MNP concentration range, in vivo, was estimated as 30-79 {mu}g g{sup -1} tissue for both gold and iron nanoparticles. The tumor dose enhancement may compensate for an increase in entrance dose associated with conventional PT when treating large, solid tumors with a spread-out Bragg peak (SOBP) technique. The use of a combined high energy Bragg peak PT with PIXE generated by MNP, or PIXE alone, may result in new treatment options for infiltrative metastatic tumors and other diffuse inflammatory diseases.

    Buried free-cysteine (Cys) residues can contribute to an irreversible unfolding pathway that promotes protein aggregation, increases immunogenic potential, and significantly reduces protein functional half-life. Consequently, mutation of buried free-Cys residues can result in significant improvement in the storage, reconstitution, and pharmacokinetic properties of protein-based therapeutics. Mutational design to eliminate buried free-Cys residues typically follows one of two common heuristics: either substitution by Ser (polar and isosteric), or substitution by Ala or Val (hydrophobic); however, a detailed structural and thermodynamic understanding of Cys mutations is lacking. We report a comprehensive structure and stability study of Ala, Ser, Thr, and Val mutations at each of the three buried free-Cys positions (Cys16, Cys83, and Cys117) in fibroblast growth factor-1. Mutation was almost universally destabilizing, indicating a general optimization for the wild-type Cys, including van der Waals and H-bond interactions. Structural response to Cys mutation characteristically involved changes to maintain, or effectively substitute, local H-bond interactions-by either structural collapse to accommodate the smaller oxygen radius of Ser/Thr, or conversely, expansion to enable inclusion of novel H-bonding solvent. Despite the diverse structural effects, the least destabilizing average substitution at each position was Ala, and not isosteric Ser. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association.

    The complement system functions as a part of the innate immune system. Inappropriate activation of the complement pathways has a deleterious effect on kidneys. Recent advances in complement research have provided new insights into the pathogenesis of glomerular and tubulointerstitial injury associated with complement activation. A new disease entity termed 'C3 glomerulopathy' has recently been proposed and is characterized by isolated C3 deposition in glomeruli without positive staining for immunoglobulins. Genetic and functional studies have demonstrated that several different mutations and disease variants, as well as the generation of autoantibodies, are potentially associated with its pathogenesis. The data from comprehensive analyses suggest that complement dysregulation can also be associated with hemolytic uremic syndrome and more common glomerular diseases, such as IgA nephropathy and diabetic kidney disease. In addition, animal studies utilizing genetically modified mice have begun to elucidate the molecular pathomechanisms associated with the complement system. From a diagnostic point of view, a noninvasive, MRI-based method for detecting C3 has recently been developed to serve as a novel tool for diagnosing complement-mediated kidney diseases. While novel therapeutic tools related to complement regulation are emerging, studies evaluating the precise roles of the complement system in kidney diseases will still be useful for developing new therapeutic approaches.

    In terms of immune regulating functions, analysis of the microbiome has led the development of therapeutic strategies that may be applicable to asthma management. This review summarizes the current literature on the gut and lung microbiota in asthma pathogenesis with a focus on the roles of innate molecules and new microbiome-mediated therapeutics. Recent clinical and basic studies to date have identified several possible therapeutics that can target innate immunity and the microbiota in asthma. Some of these drugs have shown beneficial effects in the treatment of certain asthma phenotypes and for protection against asthma during early life. Current clinical evidence does not support the use of these therapies for effective treatment of asthma. The integration of the data regarding microbiota with technologic advances, such as next generation sequencing and omics offers promise. Combining comprehensive bioinformatics, new molecules and approaches may shape future asthma treatment.

    Five studies examined the effects of positive emotion priming on the willingness to drive recklessly. In all five, young drivers were exposed to one of the following primes of positive affect: a positive mood story; happy memories; an exciting film; a relaxing film; or thoughts on the meaning in life. Following the prime, the participants were asked to report on their willingness to drive recklessly. The responses were compared to those of groups exposed either to neutral affect, another kind of positive affect, or negative affect priming. In two of the studies, participants were also asked to report on their driving styles (risky, anxious, angry, or careful) as a second dependent variable. Positive affect, especially in the form of arousal, was found to be related to higher willingness to drive recklessly. Although men tended to report higher intentions to drive recklessly, men and women did not react differently to the emotional induction. Most interestingly, positive emotions of a relaxing nature, as well as thinking about the meaning in life, lowered the willingness to engage in risky driving. The discussion emphasizes the importance of looking for new ways to use positive emotions effectively in road safety interventions, and considers the practical implications of the studies.

    A detailed Study of the Earth tide effects on the GPS kinematic/static positioning is presented in this paper by using theoretical Earth tide computation and practical GPS data processing. Tidal effects could reach up to 30 cm in Denmark and Greenland depending on the measuring time...... and the position of reference station. With a baseline less than 80 km, the difference of the Earth tide effects could reach more than 5 mm. So, in precise applications of GPS positioning, the Earth tide effect has to be taken into account even for a relative small local GPS network. Several examples are given...... for demonstrating that the Earth tide effects can be viewed by GPS surveying. They are given through static GPS data static processing, static GPS data kinematic processing, and airborne kinematic GPS data processing. In these cases, the Earth tide effects can be subtracted from the GPS results. The determination...

    Full Text Available Background: The therapeutic relationship is one of the most important and independent predictors in psychotherapy. Therapeutic relationships take place in a social environment, which shapes the mentality of therapists. One of the important aspects of this environment is financialization, which is considered to be the most significant socioeconomic phenomenon characteristic of capitalism. The aim of this paper is to discuss the effect of financialization on the attitudes of psychotherapists and on the quality of care they provide. Discussion: The paper presents a theoretical analysis of the relationship between the primary constituents of the therapeutic relationship (i.e. trust, realness, individuality of approach, honesty, truth, ethics, the good of the patient and the phenomena characteristic of the process of financialization (such as replacement of relationship for transaction, distrust, advertisement, statistics, profitability, acceptance of a lie, relativism, consumptionism, perception of own benefits. Summary: Financialization can change the therapeutic relationship through indiscriminate introjection of financialization by the therapist. The primary cognitive and behavioural effect of this process is a shift in the proportions between the foundations of therapeutic relationship towards the foundations of financialization (as defined in this article. To the best of our knowledge, this is the first article presenting the correlation between financialization and psychotherapy.

    Full Text Available Objective: To assess the effect of aquatic environment while an occupational therapeutic scenario in the development of body scheme of a child with Down Syndrome, considering the therapeutic properties of water. Description of the case: An interventionist research, with a qualitative and descriptive approach, conducted in an adapted pool of the Núcleo de Atenção Médica Integrada (NAMI of Fortaleza University (UNIFOR, Ceara, during the period of March to May, 2005. The subject of the study was a female child, aged 10 years old, diagnosed with Down Syndrome. Data collection had as instruments an interview guide for anamnesis, an evaluation form of psychomotor development, besides a field diary to record clinical observations during the sessions. This information was organized and analyzed based on clinical reasoning of occupational therapists and then described as a case study. We observed an evolution in the development of skills related to body scheme, such as the perception of fine parts of her own body, as well as large parts in someone else’s body, the imitation of positions, finishing with more active participation in activities of daily living. Final Considerations: We verified the effectiveness of occupational therapeutic activities conducted in aquatic environment for the development of the body scheme of the child in the study. This may be useful for conducting further research on the subject – whose literature is scarce – and contributing to the crescent update of occupational therapy practices.

    A clinical trial demonstrated that a therapeutic workplace could promote alcohol abstinence in homeless, alcohol-dependent adults. This secondary-data analysis examined rates of homelessness and their relation to the therapeutic workplace intervention and alcohol use during the trial. In the trial, homeless, alcohol-dependent adults could work in a therapeutic workplace for 6 months and were randomly assigned to Unpaid Training, Paid Training, or Contingent Paid Training groups. Unpaid Training participants were not paid for working. Paid Training participants were paid for working. Contingent Paid Training participants were paid for working if they provided alcohol-negative breath samples. Rates of homelessness during the study were calculated for each participant and the three groups were compared. Mixed-effects regression models were conducted to examine the relation between alcohol use (i.e., heavy drinking, drinks per drinking day, and days of alcohol abstinence) and homelessness. Unpaid Training, Paid Training, and Contingent Paid Training participants did not differ in the percentage of study days spent homeless (31%, 28%, 17%; respectively; F(2,94)=1.732, p=0.183). However, participants with more heavy drinking days (b=0.350, phomeless. Reducing heavy drinking and alcohol use may help homeless, alcohol-dependent adults transition out of homelessness.

    GABAA receptors meet all of the pharmacological requirements necessary to be considered important targets for the action of general anesthetic agents in the mammalian brain. In the following patch-clamp study, the relative modulatory effects of 2,6-dimethylcyclohexanol diastereomers were investigated on human GABAA (α1β3γ2s) receptor currents stably expressed in human embryonic kidney cells. Cis,cis-, trans,trans-, and cis,trans-isomers were isolated from commercially available 2,6-dimethylcyclohexanol and were tested for positive modulation of submaximal GABA responses. For example, the addition of 30 μM cis,cis-isomer resulted in an approximately 2- to 3-fold enhancement of the EC20 GABA current. Coapplications of 30 μM 2,6-dimethylcyclohexanol isomers produced a range of positive enhancements of control GABA responses with a rank order for positive modulation: cis,cis > trans,trans ≥ mixture of isomers > > cis,trans-isomer. In molecular modeling studies, the three cyclohexanol isomers bound with the highest binding energies to a pocket within transmembrane helices M1 and M2 of the β3 subunit through hydrogen-bonding interactions with a glutamine at the 224 position and a tyrosine at the 220 position. The energies for binding to and hydrogen-bond lengths within this pocket corresponded with the relative potencies of the agents for positive modulation of GABAA receptor currents (cis,cis > trans,trans > cis,trans-2,6-dimethylcyclohexanol). In conclusion, the stereochemical configuration within the dimethylcyclohexanols is an important molecular feature in conferring positive modulation of GABAA receptor activity and for binding to the receptor, a consideration that needs to be taken into account when designing novel anesthetics with enhanced therapeutic indices.
