    Full Text Available Affective dysregulation is at the root of many psychopathologies, including stress induced disorders, anxiety disorders, and depression. The root of these disorders appears to be an attenuated, top-down cognitive control from the prefrontal cortices over the maladaptive subcortical emotional processing. A form of mental training, long-term meditation practice can trigger meditation-specific neuroplastic changes in the brain regions underlying cognitive control and affective regulation, suggesting that meditation can act as a kind of mental exercise to foster affective regulation and possibly a cost-effective intervention in mood disorders. Increasing research has suggested that the cultivation of awareness and acceptance along with a nonjudgmental attitude via meditation promotes adaptive affective regulation. This review examined the concepts of affective regulation and meditation and discussed behavioral and neural evidence of the potential clinical application of meditation. Lately, there has been a growing trend toward incorporating the “mindfulness” component into existing psychotherapeutic treatment. Promising results have been observed thus far. Future studies may consider exploring the possibility of integrating the element of “compassion” into current psychotherapeutic approaches.

    Full Text Available Background: Infectious complications frequently occur after cardiac arrest and may be even more frequent after therapeutic hypothermia. Pneumonia is the most common infectious complication associated with therapeutic hypothermia, and it is unclear whether prophylactic antibiotics administered during this intervention can decrease the development of early-onset pneumonia. We investigated the effect of antibiotic prophylaxis on the development of pneumonia in cardiac arrest patients treated with therapeutic hypothermia. Methods: We retrospectively reviewed the medical records of patients who were admitted for therapeutic hypothermia after resuscitation for out-of-hospital cardiac arrest between January 2010 and July 2015. Patients who died within the first 72 hours or presented with pneumonia at the time of admission were excluded. Early-onset pneumonia was defined as pneumonia that developed within 5 days of admission. Prophylactic antibiotic therapy was defined as the administration of any parenteral antibiotics within the first 24 hours without any evidence of infection. Results: Of the 128 patients admitted after cardiac arrest, 68 were analyzed and 48 (70.6% were treated with prophylactic antibiotics within 24 hours. The frequency of early-onset pneumonia was not significantly different between the prophylactic antibiotic group and the control group (29.2% vs 30.0%, respectively, p = 0.945. The most commonly used antibiotic was third-generation cephalosporin, and the class of prophylactic antibiotics did not influence early-onset pneumonia. Conclusion: Antibiotic prophylaxis in cardiac arrest patients treated with therapeutic hypothermia did not reduce the frequency of pneumonia.

    Objective: To study the factors influencing therapeutic effect of 131 I in treating 783 cases of Graves disease. Methods: The values of various indexes were quantized on influencing factors such as age, sex, course of disease, mass of thyroid gland, the absorbed dose of 131 I per gram of thryoid gland, the given dose of 131 I, thyroid 24 h 131 I uptaking percentage, thyroid hormone and thyroid autoantibodys. The assessment of the therapeutic effect was made according to complete remission (including hypothyroidism) and partial remission after 131 I therapy. CMH χ 2 , Wilcoxon signed-rank test and Logistic regression were used to analyze the variable parameters before the treatment. Results: The therapeutic effect of 131 I is significant in the follow-up period (CMH χ 2 =69.21, P 131 I therapy for 12 months. The therapeutic effect was related to such factors as age thyroid mass, the absorbed dose of 131 I per gram of thryoid gland, thyroid 24 h 131 I uptaking percentage, etc (all the values of P 131 I uptaking percentage is higher, thyroid mass is bigger, thyroid gland is with noduses, the given dose of 131 I should be increased. Conversely decreased. (authors)

    This study aimed to investigate the remote effect of acupuncture (AcP) on the pain intensity and the irritability of the myofascial trigger point in the upper trapezius muscle. Forty-five patients were equally divided into three groups: patients in the placebo control group received sham AcP, those in the simple needling group were treated using simple needling, and those in the modified AcP received AcP with the rapid "screwed in and out" into multiple sites to elicit local twitch responses. The acupoints of Wai-guan and Qu-chi were treated. The outcome assessments included changes in subjective pain intensity, pressure pain threshold, range of motion, and mean amplitude of endplate noise in the myofascial trigger point region. Immediately after acupuncture, all measured parameters improved significantly in the simple needling and modified AcP groups, but not in the placebo control group. There were significantly larger changes in all parameters in the modified AcP group than that in the simple needling group. The myofascial trigger point irritability could be suppressed after a remote acupuncture treatment. It appears that needling to the remote AcP points with multiple needle insertions of modified AcP technique is a better technique than simple needling insertion of simple needling technique in terms of the decrease in pain intensity and prevalence of endplate noise and the increase in pressure pain threshold in the needling sites (represented either AcP points and or myofascial trigger points). We have further confirmed that the reduction in endplate noise showed good correlation with a decreased in pain.

    To explore the mechanism of acupuncture combined with medication for treatment of essential hypertension (EH). Sixty cases of EH were randomly divided into a combined acupuncture and medication group (group A) and a medication group (group B), 30 cases in each one, treated with acupuncture in combination with oral administration of Felodipine, and simple oral administration of Felodipine respectively. Before and after treatment, the changes of blood pressure, and the contents of E-selectin (Es), iNOS and eNOS were determined. After treatment, the blood pressure declined in either group. The total effective rate in group A was 86.7% (26/30), which was superior to that of 73.3% (22/30) in group B. After treatment, the plasma Es and iNOS contents in two groups decreased as compared with those before treatment (both P acupuncture on anti-blood pressure probably relies on the improvements in vascular endothelial cellular function so that Es, iNOS and eNOS expression can be recovered to normal level and ultimately blood pressure is adjusted.

    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.

    Although numerous clinical studies have reported that pulsed electromagnetic fields (PEMF) have a neuroprotective role in patients with diabetic peripheral neuropathy (DPN), the application of PEMF for clinic is still controversial. The present study was designed to investigate whether PEMF has therapeutic potential in relieving peripheral neuropathic symptoms in streptozotocin (STZ)-induced diabetic rats. Adult male Sprague-Dawley rats were randomly divided into three weight-matched groups (eight in each group): the non-diabetic control group (Control), diabetes mellitus with 15 Hz PEMF exposure group (DM+PEMF) which were subjected to daily 8-h PEMF exposure for 7 weeks and diabetes mellitus with sham PEMF exposure group (DM). Signs and symptoms of DPN in STZ-treated rats were investigated by using behavioral assays. Meanwhile, ultrastructural examination and immunohistochemical study for vascular endothelial growth factor (VEGF) of sciatic nerve were also performed. During a 7-week experimental observation, we found that PEMF stimulation did not alter hyperglycemia and weight loss in STZ-treated rats with DPN. However, PEMF stimulation attenuated the development of the abnormalities observed in STZ-treated rats with DPN, which were demonstrated by increased hind paw withdrawal threshold to mechanical and thermal stimuli, slighter demyelination and axon enlargement and less VEGF immunostaining of sciatic nerve compared to those of the DM group. The current study demonstrates that treatment with PEMF might prevent the development of abnormalities observed in animal models for DPN. It is suggested that PEMF might have direct corrective effects on injured nerves and would be a potentially promising non-invasive therapeutic tool for the treatment of DPN.

    Attention deficit hyperactivity disorder (ADHD) is a fixed pattern of disregard and hyperactivity that is much more severe than what is normal in children of the same age. Multiple drugs are used for the treatment of children with ADHD; however, their side effects and efficacy are not clearly known. This study was designed to evaluate and compare the therapeutic effects of two drugs, that is, omega-3 and methylphenidate hydrochloride (Ritalin(®)), used to treat patients with ADHD. In a randomized, placebo control clinical trial in Yazd, Iran, 85 ADHD children were divided into two experimental and one control groups. Thus, 29 subjects were treated with Ritalin(®), 28 subjects received omega-3, and the remaining 28 received placebo. The data collection tools used in this study consisted of the Conners' Parent Rating Scale and Teacher Rating Scale. The scores obtained from these questionnaires were analyzed using chi-square test and paired t-test in PASW Statistics. The average age of the population was 8.22 (± 1.65) years. Significant associations were observed between Ritalin(®) therapy and the changes before and after the treatment, and the omega-3 treatment and the changes before and after treatment (p 0.050). Omega-3 had considerable efficacy as well as Ritalin(®) (P = 0.001). More attention should be given to screening, prevention, and treatment with omega-3 and its effective role in the development of the brain and mental health, and increasing children's attention span and thinking ability.

    2012-01-01

    Cardiovascular disease is the leading cause of death worldwide and is often associated with partial or full occlusion of the blood vessel network in the affected organs. Restoring blood supply is critical for the successful treatment of cardiovascular diseases. Therapeutic angiogenesis provides a valuable tool for treating cardiovascular diseases by stimulating the growth of new blood vessels from pre-existing vessels. In this review, we discuss strategies developed for therapeutic angiogenesis using single or combinations of biological signals, cells and polymeric biomaterials. Compared to direct delivery of growth factors or cells alone, polymeric biomaterials provide a three-dimensional drug-releasing depot that is capable of facilitating temporally and spatially controlled release. Biomimetic signals can also be incorporated into polymeric scaffolds to allow environmentally-responsive or cell-triggered release of biological signals for targeted angiogenesis. Recent progress in exploiting genetically engineered stem cells and endogenous cell homing mechanisms for therapeutic angiogenesis is also discussed. PMID:22916079

    2013-01-01

    Full Text Available The effective treatment of castrate-resistant prostate cancer (CRPC has proven to be very challenging. Until recently, docetaxel was the only therapeutic demonstrated to extend overall patient survival. Yet recently, a considerable number of new therapeutics have been approved to treat CRPC patients. These remarkable advances now give new tools for the therapeutic management of late-stage prostate cancer. In this review, we will examine mechanistic and clinical data of several newly approved therapeutics including the chemotherapeutic cabazitaxel, antiandrogen enzalutamide, endocrine disruptor abiraterone acetate, immunotherapy sipuleucel-T, and bone-targeting radiopharmaceutical alpharadin. In addition, we will examine other promising therapeutics that are currently in Phase III trials.

    India, a country of diverse cultures, languages, life styles, and ethnicities, is becoming a land of economic change, political stability, technological advancement, and changing traditional structures of relationships as well as health consciousness. Being known for its ancient traditions, rituals, religious orientation, spiritual outlook and folk beliefs, Indian families attempt to continue certain healthy and traditional elements such as warmth, strong bond, hierarchy, extended support, cultural orientation, shared values and time, tolerance, respect for the aged and inculcation of religious teachings and traditions in families. These factors, or practices, in fact have strong therapeutic value in supplementing the growth and development of individuals in the family system in spite of its transitional position. This paper deals with the review of family-based mental health services and focuses on the changing trends of those practices in India and the advancement of Indian families in their engaging ability with mentally ill members as well as with the treating team.

  13. Charcot as therapeutic interventionist and treating neurologist.

    Although Jean-Martin Charcot's best-known medical and scientific contributions relate to anatomical-clinical correlation, he was also a highly regarded physician. His published lectures and articles, as well as documents at the Bibliothèque Charcot, demonstrate his active interest in therapeutic interventions and in bringing new experimental treatments to France for study. He investigated the efficacy of bromides for epilepsy, colchicine for gout, and ergots and anticholinergic drugs for Parkinson's disease. Nonpharmacologic treatments in which he took interest included physical rehabilitation/speech therapy, hydrotherapy, electrical stimulation of weakened muscles, isolation, and exotic interventions such as suspension and vibratory treatments with special chairs and helmets. Letters from his patients reveal an active interchange, with patients complimenting Charcot on successful treatments but also demanding more effective ones when his prescriptions did not abate their conditions. These documents demonstrate that Charcot was not a therapeutic nihilist but was particularly active in therapeutic investigations in the context of 19th-century medical science.

    This study hypothesized that autologous cell transplantation therapy could have greater therapeutic efficacy in juvenile patients than in adult patients, related to differences in sirtuin1 (SIRT1) expression in transplanted cells. A model of heart failure was established in mini-pigs by using coronary artery occlusion. Stem cell cultures were established from juvenile and adult mini-pigs. The cells were prepared as cell sheets and transplanted into corresponding adult or juvenile mini-pigs, and the therapeutic effects were examined in vivo and in vitro. Next, SIRT1 knockdown cells were established using small interfering RNAs for SIRT1, and the therapeutic effects of the cells were examined in vitro and in vivo in Lewis rat models of heart failure. Cardiac function showed significantly more improvement in juvenile than in adult pigs. Histologic analysis revealed significant reduction of myocardial fibrosis and hypertrophic response in juvenile pigs. In vitro analysis demonstrated that doubling time was significantly shorter, the ratio of Ki67-positive cells was significantly greater, and the expression of SIRT1, hypoxia-induced factor-1α, hepatocyte growth factor, and stromal cell-derived factor-1 was significantly upregulated in juvenile cells. SIRT1 knockdown cells showed decreased proliferation and cytokine release potential compared with wild-type cells. Transplantation of SIRT1 knockdown stem cell sheets showed lesser improvement of cardiac function after severe heart failure in Lewis rats than in controls. Sirtuin1 expression in transplanted cells enhances the skeletal stem cell sheet therapeutic effects for treating severe heart failure in a juvenile animal model.

    2016-04-01

    Epstein-Barr virus (EBV) infects most people worldwide. EBV has oncogenic potential and is strongly associated with several lymphomas and carcinomas, including nasopharyngeal carcinoma (NPC), that together total 200,000 cases of cancer each year. All EBV-associated cancers express viral proteins that allow highly selective immunotherapeutic targeting of the malignant cells. A number of therapeutic EBV vaccines have been tested in clinical trials with evidence of immune boosting and clinical responses in NPC patients. Therapeutic vaccination could be used after adoptive T-cell transfer to increase and sustain the number of infused T-cells or combined with immunotherapies acting at different stages of the cancer immunity cycle to increase efficacy. The therapeutic EBV vaccines tested to date have been well tolerated with minimal off-target toxicity. A safe therapeutic vaccine that was also able to be mass produced could, in principle, be used to vaccinate large numbers of patients after first line therapy to reduce recurrence.

    To provide a set of the self-help and mutual-aid treatment with moxibustion to deal with myofasicial pain syndrome (MPS) of the back for the military soldiers. Fifty-eight cases were randomly devided into a moxibustion group (30 cases) and a plaster application group (28 cases). In the moxibustion group, the suspended moxibustion was applied to Yanglingquan (GB 34) for 15 min. The moxibustion massage device was used to massage the pain area. Under the physician's guides, the self-help or mutual-aid treatment was adopted. In the plaster application group, Goupi Gao (a black plaster used in TCM) was used on the local pain area. The treatment was given once every day in either group, lasting for 5 days. The clinical symptom scale, clinical physical sign scale, functional disturbance scale, functional disturbance index, comprehensive economic benefit and the others were adopted to analyze and compare the clinical efficacies between the two groups. Both moxibustion and the plaster application achieved a certain efficacy on MPS of the back in the soldiers and either of them received the obvious improvements in the clinical symptoms, physical signs and functional disturbance (P military soldiers. It reduces the conventional medical cost and the military medical expenditure. This therapeutic approach is suitable to be promoted in the military.

    The treatment of intracranial complicated aneurysms remains challenging. In patients with complicated aneurysms that are neither clippable nor coilable, flow alteration treatment (FAT) with a combined procedure of proximal/distal occlusion or trapping of an aneurysm with bypass surgery has been reported. However, it is difficult to predict whatever FAT can achieve aneurysmal obliteration without ischemic complications. A 69-year-old female was incidentally diagnosed with a left vertebral artery (VA) fusiform aneurysm distal to the left posterior inferior cerebellar artery (PICA). Because one-year follow-up three-dimensional computed tomography angiography showed that the aneurysm grew significantly, surgical management was considered the therapy of choice. For determining treatment strategies, we assumed left VA occlusion at the proximal to the left PICA as a FAT model and performed computational fluid dynamics (CFD) analyses. The FAT model had much lower wall shear stress and shear rate at the aneurysm dome than presumed thresholds necessary to thrombus formation, while those at the PICA were obviously higher than the thresholds, and streamlines into the left PICA from the distal VA were preserved. These findings theoretically meant that surgical occlusion of the left VA proximal to the left PICA and aneurysm would induce intra-aneurysmal thrombus formation with preservation of the left PICA flow. The treatment was performed successfully and achieved the predicted results. CFD simulations may be useful to predict effects of FAT for complicated aneurysms.

    Full Text Available Neurodegenerative diseases affect millions of individuals worldwide. So far, no disease-modifying drug is available to treat patients, making the search for effective drugs an urgent need. Neurodegeneration is triggered by the activation of several cellular processes, including oxidative stress, mitochondrial impairment, neuroinflammation, aging, aggregate formation, glutamatergic excitotoxicity, and apoptosis. Therefore, many research groups aim to identify drugs that may inhibit one or more of these events leading to neuronal cell death. Venoms are fruitful natural sources of new molecules, which have been relentlessly enhanced by evolution through natural selection. Several studies indicate that venom components can exhibit selectivity and affinity for a wide variety of targets in mammalian systems. For instance, an expressive number of natural peptides identified in venoms from animals, such as snakes, scorpions, bees, and spiders, were shown to lessen inflammation, regulate glutamate release, modify neurotransmitter levels, block ion channel activation, decrease the number of protein aggregates, and increase the levels of neuroprotective factors. Thus, these venom components hold potential as therapeutic tools to slow or even halt neurodegeneration. However, there are many technological issues to overcome, as venom peptides are hard to obtain and characterize and the amount obtained from natural sources is insufficient to perform all the necessary experiments and tests. Fortunately, technological improvements regarding heterologous protein expression, as well as peptide chemical synthesis will help to provide enough quantities and allow chemical and pharmacological enhancements of these natural occurring compounds. Thus, the main focus of this review is to highlight the most promising studies evaluating animal toxins as therapeutic tools to treat a wide variety of neurodegenerative conditions, including Alzheimer’s disease, Parkinson

    Hemophilia A is an X-linked rescessive bleeding disorder that results from F8 gene aberrations. Previously, we established embryonic stem (ES) cells (tet-226aa/N6-Ainv18) that secrete human factor VIII (hFVIII) by introducing the human F8 gene in mouse Ainv18 ES cells. Here, we explored the potential of cell transplantation therapy for hemophilia A using the ES cells. Transplant tet-226aa/N6-Ainv18 ES cells were injected into the spleens of severe combined immunodeficiency (SCID) mice, carbon tetrachloride (CCl4)-pretreated wild-type mice, and CCl4-pretreated hemophilia A mice. F8 expression was induced by doxycycline in drinking water, and hFVIII-antigen production was assessed in all cell transplantation experiments. Injecting the ES cells into SCID mice resulted in an enhanced expression of the hFVIII antigen; however, teratoma generation was confirmed in the spleen. Transplantation of ES cells into wild-type mice after CCl4-induced liver injury facilitated survival and engraftment of transplanted cells without teratoma formation, resulting in hFVIII production in the plasma. Although CCl4 was lethal to most hemophilia A mice, therapeutic levels of FVIII activity, as well as the hFVIII antigen, were detected in surviving hemophilia A mice after cell transplantation. Immunolocalization results for hFVIII suggested that transplanted ES cells might be engrafted at the periportal area in the liver. Although the development of a safer induction method for liver regeneration is required, our results suggested the potential for developing an effective ES-cell transplantation therapeutic model for treating hemophilia A in the future.

    We all have an irrational fear or two. Some of us get scared by an unexpected visit from a spider in our house; others get nervous when they look down from a high building. Fear is an evolutionary and adaptive function that can promote self-preservation and help us deal with the feared object or situation. However, when this state becomes excessive, it might develop into psychological disorders such as phobias, producing high anxiety and affecting everyday life. The Therapeutic Lamp is an interactive projection-based augmented-reality system for treating small-animal phobias. It aims to increase patient-therapist communication, promote more natural interaction, and improve the patient's engagement in the therapy.

    In this trial, long-term therapeutic effects and clinical improvements in Chinese chronic heart failure patients optimized by QuickOpt or echocardiography were compared for atrioventricular (AV) and interventricular (VV) delay optimizations after cardiac resynchronization therapy (CRT) with pacing (CRT-P) or with pacing and defibrillator (CRT-D) therapy. One hundred and ninety-six subjects (50%) had dilated cardiomyopathy, 108 (27.6%) had ischemic heart disease and 112 (28.6%) were hypertensive and were randomized into QuickOpt (198) or echocardiographic optimization (control) (194) groups at ≤2-weeks post-implantation. Programmed AV/VV delay was optimized at baseline and at 3 and 6 months. Left ventricular end-systolic volume (LVESV), New York Heart Association (NYHA) class, specific activity scale (SAS), and the six-minute walk tests (6MWT) were evaluated by blinded researchers at 12 months. Of the QuickOpt group, LVESV decreased significantly by 24.7% ± 33.9% compared with baseline, while LVESV of Controls decreased by 25.1% ± 36.1% (P = 0.924). NYHA class, SAS and 6MWT also improved similarly in both groups at 12 months. Mortality in both groups was not significantly different (11.0% vs 7.6%, P = 0.289). However, there was a significant difference in the time required for optimization by QuickOpt compared with echocardiography (3.33 ± 3.11 vs 58.79 ± 27.03 minutes, P < 0.000).

    Full Text Available Applying head-mounted displays (HMDs and virtual reality scenarios in virtual reality exposure therapy (VRET promises to alleviate combat-related post-traumatic stress disorders (among others. Its basic premise is that, through virtual scenarios, patients may re-engage immersively with situations that provoke anxiety, thereby reducing fear and psychosomatic stress. In this context, HMDs and visualizations should be considered not merely as devices for entertainment purposes or tools for achieving pragmatic objectives but also as a means to instruct and guide patients’ imagination and visual perception in triggering traumatic experiences. Under what perceptual and therapeutic conditions is virtual therapy to be considered effective? Who is the “ideal” patient for such therapy regimes, both in terms of his/her therapeutic indications and his/her perceptual readiness to engage with VR scenarios? In short, how are “treatable” patients conceptualized by and within virtual therapy? From a media-theory perspective, this essay critically explores various aspects of the VRET application Bravemind in order to shed light on conditions of virtual exposure therapy and conceptions of subjectivity and traumatic experience that are embodied and replicated by such HMD-based technology.

    Abstract Glioblastoma (GBM), an aggressive grade IV astrocytoma, is the most common primary malignant adult brain tumor characterized by extensive invasiveness, heterogeneity, and angiogenesis. Standard treatment options such as radiation and chemotherapy have proven to be only marginally effective in treating GBM because of its invasive nature. Therefore, extensive efforts have been put forth to develop tumor‐tropic stem cells as viable therapeutic vehicles with potential to treat even the most invasive tumor cells that are harbored within areas of normal brain. To this end, we discovered a newly described NG2‐expressing cell that we isolated from a distinct pericyte subtype found abundantly in cultures derived from peripheral muscle. In this work, we show the translational significance of these peripherally derived neural‐like stem cells (NLSC) and their potential to migrate toward tumors and act as therapeutic carriers. We demonstrate that these NLSCs exhibit in vitro and in vivo GBM tropism. Furthermore, NLSCs did not promote angiogenesis or transform into tumor‐associated stromal cells, which are concerns raised when using other common stem cells, such as mesenchymal stem cells and induced neural stem cells, as therapeutic carriers. We also demonstrate the potential of NLSCs to express a prototype therapeutic, tumor necrosis factor α‐related apoptosis‐inducing ligand and kill GBM cells in vitro. These data demonstrate the therapeutic potential of our newly characterized NLSC against GBM. Stem Cells Translational Medicine 2017;6:471–481 PMID:28191774

    2017-08-01

    Muscle is primarily known for its mechanical roles in locomotion, maintenance of posture, and regulation of cardiac and respiratory function. There are numerous medical conditions that adversely affect muscle, myopathies that disrupt muscle development, regeneration and protein turnover to detrimental effect. Skeletal muscle is also a vital secretory organ that regulates thermogenesis, inflammatory signaling and directs context specific global metabolic changes in energy substrate preference on a daily basis. Myopathies differ in the causative factors that drive them but share common features including severe reduction in quality of life and significantly increased mortality all due irrefutably to the loss of muscle mass. Thus far clinically viable approaches for preserving muscle proteins and stimulating new muscle growth without unwanted side effects or limited efficacy has been elusive. Over the last few decades, evidence has emerged through in vitro and in vivo studies that suggest the nuclear receptors REV-ERB and ROR might modulate pathways involved in myogenesis and mitochondrial biogenesis. Hinting that REV-ERB and ROR might be targeted to treat myopathies. However there is still a need for substantial investigation into the roles of these nuclear receptors in in vivo rodent models of degenerative muscle diseases and acute injury. Although exciting, REV-ERB and ROR have somewhat confounding roles in muscle physiology and therefore more studies utilizing in vivo models of skeletal muscle myopathies are needed. In this review we highlight the molecular forces driving some of the major degenerative muscular diseases and showcase two promising molecular targets that may have the potential to treat myopathies: ROR and REV-ERB.

    Hepatitis B virus (HBV) is a member of Hepadnavirus family, which leads to chronic infection in around 5% of patients with a high risk of developing liver cirrhosis, liver failure, and hepatocellular carcinoma. 1 Despite the availability of prophylactic vaccines against hepatitis B for over 3 decades, there are still more than 2 billion people have been infected and 240 million of them were chronic. Antiviral therapies currently used in the treatment of CHB (chronic hepatitis B) infection include peg-interferon, standard α-interferon and nucleos/tide analogs (NAs), but none of them can provide sustained control of viral replication. As an alternative strategy, therapeutic vaccines for CHB patients have been widely studied and showed some promising efficacies in dozens of preclinical and clinical trials. In this article, we review current research progress in several types of therapeutic vaccines for CHB treatment, including protein-based vaccines, DNA-based vaccines, live vector-based vaccines, peptide-based vaccines and cell-based therapies. These researches may provide some clues for developing new treatments in CHB infection.

    The therapeutic effects of homoeopathic Arsenicum album potencies were investigated in-vitro, using a continuous cell line (MT4), pre-intoxicated with arsenic trioxide (As(2)O(3)), and then treated with succussed and unsuccussed homoeopathic potencies, 6CH, 30CH and 200CH. This study aimed to verify the homoeopathic law of similars and to determine whether potencies diluted beyond Avogadro's constant had physiological effects on cells; whether various potencies would cause different effects as suggested by the concept of hormesis; whether succussed and unsuccussed homoeopathic potencies had different effects on the cells; and to establish whether a biotechnological method could be used to evaluate the above. As(2)O(3) was used to pre-intoxicate and the MTT assay was used to measure the percentage cytotoxicity and half maximal inhibitory concentration (IC(50)) of the cells. The homoeopathic potencies of Arsenicum album (6CH, 30CH and 200CH) were prepared by either succussing or allowing to diffuse for 30 s. After pre-intoxication of the MT4 cells with the IC(50) As(2)O(3) and treatment with succussed and unsuccussed Arsenicum album (6CH-200CH), the cell viability increased with increasing potency from 81% to 194% (over 72 h). The treatments and the times of exposure were found to be statistically significant determinants of cell viability, whereas succussion did not cause any significant variation in the results. The study provided evidence that a biotechnological method (namely cell viability) may be used to scientifically evaluate the physiological effects of homoeopathic potencies on human cells; it confirmed that the homoeopathic potencies did have therapeutic effects; and that succussion was not required in the potentization method in order to produce a curative remedy.

  15. Therapeutic potential for thyroid hormone receptor-beta selective agonists for treating obesity, hyperlipidemia and diabetes.

    Obesity and metabolic syndrome are increasing dramatically worldwide, contributing to cardiovascular morbidity and mortality. There are currently few safe and efficacious therapeutics for obesity and most strategies are focused on appetite suppression. Thyroid hormones reduce adiposity via increased metabolic rate, but unfortunately they cause large changes in metabolic rate and direct cardiac acceleration, making them useless for treating obesity. Thyroid hormone receptors (TRs) work as transcription factors and two subtypes exist: TRalpha and TRbeta. TRalpha mediates tachycardia and much of the metabolic rate effect, while TRbeta mediates cholesterol and TSH lowering effects of thyroid hormones. TRbeta activation modestly increases metabolic rate such that a therapeutic window of 5-10 fold increases in metabolic rate can be seen without tachycardia. This was initially studied in TRalpha(1)(-/-) mice. Recent structure activity work has resulted in the discovery of several TRbeta selective thyromimetics such as KB-141. Studies with KB-141 show that it has a 10-fold window in which therapeutic increases in metabolic rate are seen without tachycardia or cardiac hypertrophy. This agent lowers cholesterol in rats and primates. In primates, KB-141 causes significant weight and cholesterol reduction in addition to the independent risk factor Lp(a). These effects were seen without any effect on heart rate, unlike thyroid hormone (T(3)). Further work with TRbeta selective agents is warranted and recent work suggests the possibility of developing compounds that selectively penetrate different tissues which may have an even more desirable therapeutic window. Selective thyromimetics, therefore, may be useful as adjunctive therapy to appetite suppressants along with exercise and diet restriction.

    Seborrheic dermatitis is one of those conditions that dermatologists and patients alike tend to find a routine for, and in many cases those routines are hard to break. And, unlike the new treatment paradigms for eczema, acne, and even actinic keratoses, combination therapies for addressing the disease process typically have not been a part of the approach to treating seborrheic dermatitis. However, with the advent of new therapies and vehicles as well as a better understanding of how neutrophils and free oxygen radicals impact inflammation,1 there are new options to maintain and control the disease process of seborrheic dermatitis to minimize flares. Although the needs of the scalp, face and chest are different, as are the variations in skin types, the fundamental mechanisms of the inflammatory process are often the same. If it is understood that seborrheic dermatitis is histologically classified as a papulosquamous disorder with paucineutrophilic and lymphocytic infiltrates, and if the trigger and etiologic agent most likely is Malassezia furfur, then the ideal mechanisms of action of therapies should be directed as such

    The patients suffered from diabetes mellitus (DM) are increasing year by year through the world. DM is classified into two groups, insulin-dependent type 1 and non-insulin-dependent type 2. Recent research has demonstrated that vanadate (VO3-, oxidation state+5) and vanadyl (VO2+, oxidation state+4) both mimic various actions of insulin in cellular systems. In 1985, vanadate given orally as a drinking water to streptozotocin-induced hyperglycemic type 1 diabetic rats (STZ-rats) was found to reduce the high levels of blood glucose down to normal levels and ameliorated many of the aberrations induced by hyperglycemia. In 1990, we proposed first orally active vanadyl complexes such as vanadyl-cysteine methylester and vanadyl-oxalate complexes in STZ-rats. Since then, we have developed orally active vanadyl complexes with different coordination modes. Among them, vanadyl-picolinate complexes with VO(N2O2) coordination mode were found to be potent orally active insulin-mimetic agents, on the basis of the results on in vitro test using isolated rat adipocytes with respect to the inhibition of the release of free fatty acids (FFA) from the cells and in vivo evaluation (intraperitoneal injection and oral administration) in STZ-rats. Based on the results, the usefulness of vanadium complexes in treating and preventing DM has been revealed, proposing a possible action mechanism.

    There are no effective and approved therapies against devastating ocular injuries caused by vesicating chemical agents sulfur mustard (SM) and nitrogen mustard (NM). Herein, studies were carried out in rabbit corneal cultures to establish relevant ocular injury biomarkers with NM for screening potential efficacious agents in laboratory settings. NM (100 nmol) exposure of the corneas for 2 h (cultured for 24 h), showed increases in epithelial thickness, ulceration, apoptotic cell death, epithelial detachment microbullae formation, and the levels of VEGF, cyclooxygenase-2 (COX-2) and matrix metalloproteinase-9 (MMP-9). Employing these biomarkers, efficacy studies were performed with agent treatments 2 h and every 4 h thereafter, for 24 h following NM exposure. Three agents were evaluated, including prescription drugs dexamethasone (0.1%; anti-inflammatory steroid) and doxycycline (100 nmol; antibiotic and MMP inhibitor) that have been studied earlier for treating vesicant-induced eye injuries. We also examined silibinin (100 μg), a non-toxic natural flavanone found to be effective in treating SM analog-induced skin injuries in our earlier studies. Treatments of doxycycline + dexamethasone, and silibinin were more effective than doxycycline or dexamethasone alone in reversing NM-induced epithelial thickening, microbullae formation, apoptotic cell death, and MMP-9 elevation. However, dexamethasone and silibinin alone were more effective in reversing NM-induced VEGF levels. Doxycycline, dexamethasone and silibinin were all effective in reversing NM-induced COX-2 levels. Apart from therapeutic efficacy of doxycycline and dexamethasone, these results show strong multifunctional efficacy of silibinin in reversing NM-induced ocular injuries, which could help develop effective and safe therapeutics against ocular injuries by vesicants. -- Highlights: ► Established injury biomarkers in rabbit corneal culture with nitrogen mustard (NM) ► This NM model is a cost effective

    Visceral adipose tissue (AT) obtained from surgical waste during routine ovariectomies was used as a source for isolating canine mesenchymal stem cells (MSCs). As determined by cytofluorimetry, passage 2 cells expressed MSC markers CD44 and CD90 and were negative for lineage-specific markers CD34 and CD45. The cells differentiated toward osteogenic, adipogenic, and chondrogenic directions. With therapeutic aims, 30 dogs (39 joints) suffering from elbow dysplasia (ED) and osteoarthritis (OA) were intra-articularly transplanted with allogeneic MSCs suspended in 0.5% hyaluronic acid (HA). A highly significant improvement was achieved without any medication as demonstrated by the degree of lameness during the follow-up period of 1 y. Control arthroscopy of 1 transplanted dog indicated that the cartilage had regenerated. Histological analysis of the cartilage biopsy confirmed that the regenerated cartilage was of hyaline type. These results demonstrate that transplantation of allogeneic adipose tissue-derived mesenchymal stem cells (AT-MSCs) is a novel, noninvasive, and highly effective therapeutic tool in treating canine elbow dysplasia.

    Enhancing therapeutic efficacy is essential for successful treatment of chemoresistant cancers such as metastatic hormone-refractory prostate cancer (HRPC). To improve the efficacy of doxorubicin (DOX) for treating chemoresistant disease, the feasibility of using nanodiamond (ND) particles was investigated. Utilizing the pH responsive properties of ND, a novel protocol for complexing NDs and DOX was developed using a pH 8.5 coupling buffer. The DOX loading efficiency, loading on the NDs, and pH responsive release characteristics were determined utilizing UV-Visible spectroscopy. The effects of the ND-DOX on HRPC cell line PC3 were evaluated with MTS and live/dead cell viability assays. ND-DOX displayed exceptional loading efficiency (95.7%) and drug loading on NDs (23.9 wt%) with optimal release at pH 4 (80%). In comparison to treatment with DOX alone, cell death significantly increased when cells were treated with ND-DOX complexes demonstrating a 50% improvement in DOX efficacy. Of the tested treatments, ND-DOX with 2.4 μg mL(-1) DOX exhibited superior efficacy (60% cell death). ND-DOX with 1.2 μg mL(-1) DOX achieved 42% cell death, which was comparable to cell death in response to 2.4 μg mL(-1) of free DOX, suggesting that NDs aid in decreasing the DOX dose necessary to achieve a chemotherapeutic efficacy. Due to its enhanced efficacy, ND-DOX can be used to successfully treat HRPC and potentially decrease the clinical side effects of DOX.

    To investigate the therapeutic efficacy of endoscopic variceal ligation (EVL) for treating various types of gastric varices (GV) by reviewing patient cases in order to identify the influencing factors of EVL-related recurrence and rebleeding. The medical records of 101 GV cases treated by EVL in our department between January 2008 and October 2012 were retrospectively reviewed. The cases were grouped according to GV type: type 1 (GOV1, n = 63), type 2 (GOV2, n = 18), GOV1 coexisting with GOV2 (n = 11), isolated GOV1 (IGV1, n = 9), and GOV2 (IGV2, n = 0). Data from follow-up examinations (range: 1.5 - 48.0 months, average: 14.9 +/- 9.1 months) were extracted for analysis and included early (less than 72 h after EVL) and late (72 h to 6 weeks after EVL) rebleeding and recurrence. In addition, data from computed tomography (CT) or CT angiography (CTA), performed in 32 of the patients, were extracted to determine the influence of supplying veins, gastrorenal or splenorenal shunts, and portal vein and/or splenic vein diameters on GV recurrence. Data analysis was carried out by ANOVA, Chi-square, Fisher's exact or rank-sum tests, as appropriate. Kaplan-Meier analysis was used to evaluate the time of first recurrent bleeding, and the log-rank test was used to compare between-group differences. GOV2 and IGV1 varices were more severe than the varices of GOV1 (GOV2 and GOV1: u = -2.960; IGV1 and GOV1: u = -2.871; both P less than 0.05). GOV1 had a significantly lower recurrence rate than all other GV types (x2 = 7.054, P less than 0.05). The CT and CTA data indicated that all GV were supplied by left gastric veins, while 83.3% of IGV1 had blood supplementation by left gastric veins and short gastric or posterior gastric veins, and 100% of IGV1 had gastrorenal or splenorenal shunts. Approximately one-half of the total GV cases (56.3%, 18/32) had gastrorenal or splenorenal shunts, and this parameter was correlated with portal vein diameter (t = -2.766, P less than 0.05). The

    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

    Florfenicol (FLO) is a broad-spectrum antibacterial agent for treatment of bacteriosis of piglets in veterinary practice. To study the toxicity to the hematopoietic and lymphoid organs of piglets treated with a therapeutic dose of FLO, 20 healthy weaned piglets were selected and randomly divided into two groups. Piglets in the FLO group were fed with fodder supplemented with 30mg/kg BW of FLO twice a day for 10 days. Blood samples were drawn at four time points: 1 day before FLO administration and 1, 7, and 14 days post-withdrawal. Three or four piglets were euthanized at each time point post-withdrawal and tissue samples (bone marrow, thymus and spleen) were collected for fixation and cryostorage. The levels of classical swine fever virus (CSFV) antibody against the vaccine, the concentrations of Hsp70 and IL-6 in serum and Hsp70 in tissues, and the mRNA expression levels of B-cell lymphoma 2 (bcl-2) and tumor suppressor p53 were detected, the hematology of the piglets were analyzed, and the histopathology and the status of apoptosis of the hematopoietic and lymphoid organs was examined. The results showed changes in several indicators in the FLO group 1 day post-withdrawal: the concentration of red blood cells (RBCs) was decreased, and that of platelets (PLTs) was significantly lower (p<0.05); the volumes of RBC and PLT were increased; the sum of blood lymphocytes was statistically decreased (p<0.05); the concentration of IL-6 was significantly increased (p<0.05); the concentrations of Hsp70 in serum and tissues were increased; obvious atrophy of the hematopoietic cell lines and partial replacement by fat cells were observed in bone marrow; thymus and spleen tissues showed lower concentrations and sparser arrangement of lymphocytes in the thymic medulla and white pulp of the spleen respectively; and the mRNA expression levels of bcl-2 in the three tissues were up-regulated, while that of p53 was down-regulated. With time after cessation of FLO administration, the

    Full Text Available The survival rate of commotio cordis is low, and there is often associated neurological disability if return of spontaneous circulation (ROSC can be achieved. We report a case of commotio cordis treated with therapeutic hypothermia (TH that demonstrated a favorable outcome. A 16-year-old female was transferred to our emergency department (ED for collapse after being struck in the chest with a dodgeball. She has no history of heart problems. She was brought to our ED with pulseless ventricular tachycardia (VT, and ROSC was achieved with defibrillation. She was comatose at our ED and was treated with TH at a target temperature of 33°C for 24 hours. After transfer to the intensive care unit, pulseless VT occurred, and defibrillation was performed twice. She recovered to baseline neurologic status with the exception of some memory difficulties.

    The prognosis of brain cancer glioblastoma (GBM) is poor, and despite intense research, there have been no significant improvements within the last decade. This stasis implicates the need for more novel therapeutic investigation. One such option is the use of nanoparticles (NPs), which can be beneficial due to their ability to penetrate the brain, overcome the blood-brain barrier and take advantage of the enhanced permeation and retention effect of GBM to improve specificity. Rare earth elements possess a number of interesting natural properties due to their unique electronic configuration, which may prove therapeutically advantageous in an NP formulation. The underexplored exciting potential for rare earth elements to augment the therapeutic potential of NPs in GBM treatment is discussed in this review.

  12. 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.

    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

    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.

    Cancer is a prime healthcare problem that is significantly responsible for universal mortality. Despite distinguished advancements in medical field, chemotherapy is still the mainstay for the treatment of cancers. During chemotherapy, approximately 90% of the administered dose goes to normal tissues, with mere 2-5% precisely reaching the cancerous tissues. Subsequently, the resultant side effects and associated complications lead to dose reduction or even discontinuance of the therapy. Tumor directed therapy therefore, represents a fascinating approach to augment the therapeutic potential of anticancer bioactives as well as overcomes its side effects. The selective overexpression of LHRH receptors on human tumors compared to normal tissues makes them a suitable marker for diagnostics, molecular probes and targeted therapeutics. These understanding enabled the rational to conjugate LHRH with various cytotoxic drugs (doxorubicin, DOX; camptothecin etc.), cytotoxic genes [small interfering RNA (siRNA), micro RNA (miRNA)], as well as therapeutic nanocarriers (nanoparticles, liposomes or dendrimers) to facilitate their tumor specific delivery. LHRH conjugation enhances their delivery via LHRH receptor mediated endocytosis. Numerous cytotoxic analogs of LHRH were developed over the past two decades to target various types of cancers. The potency of LHRH compound were reported to be as high as 5,00-10,00 folds compared to parent molecules. The objective of this review article is to discuss reports on various LHRH analogs with special emphasis on their prospective application in the medical field. The article also focuses on the attributes that must be taken into account while designing a LHRH therapeutics with special account to the biochemistry and applications of these conjugates. The record on various cytotoxic analogs of LHRH are also discussed. It is anticipated that the knowledge of therapeutic and toxicological aspects of LHRH compounds will facilitate the

    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.

    The effects of fig tree latex in treating teat papillomatosis in cow in comparison with salicylic acid were evaluated. For this purpose, 12 cows of 1-3 years of age (average 2.25) affected by teat papillomatosis were divided into three groups. In group A, four cows were treated by fig tree (Ficus carica) latex; in group B, four cows were treated with 10% salicylic acid solution and in group C, four cows were kept as control animals receiving no treatment. Animals in each treatment group received their treatment once every 5 days. In groups A and B, de-epithelialization and shrinking of the warts began from the fifth day of treatment and all the warts disappeared within 30 days. However, in the control group no changes in the number of warts were observed until day 15 but thereafter a number of warts disappeared spontaneously in some of the animals. Both salicylic acid and fig tree latex were evaluated as having similar therapeutic effects in treating teat papillomatosis in cow.

    Purpose: To investigate the influence of therapeutic parameters on local control in T2-T3 anal carcinoma treated by chemo-radiotherapy or radiation therapy alone. Materials and Methods: From 1976 to 1993, 137 patients with anal carcinoma staged T2 (85) or T3 (52) completed curative sphincter-conservating treatment, 54 with radiotherapy alone and 83 with concomitant chemo-radiotherapy. Radiation therapy was delivered in two sequences with a median gap of 46 days. The two main techniques used for the first sequence were a direct perineal cobalt field ± a sacral arc field with a median dose of 30 Gy/10 fractions/19 days (27.7%) and two antero-posterior opposed pelvic fields (≥ 6 MV photons) with a median dose of 40 Gy/20 fractions/31 days (62%). Iridium-192 implant boost was used in 116 patients (median dose 20 Gy, Paris system) and external radiation boost in 21 patients (median dose 20 Gy/10 fractions/13 days). Generally the chemoradiotherapy patients received starting on day 1 an IV bolus of Mitomycin-C (0.4 mg/kg, maximum 20 mg) and a 5-day continuous infusion of 5-fluorourcil 600-800 mg/m 2 /day. For surviving patients median follow-up was 65 months. Univariate and multivariate analyses were carried out to determine therapeutic parameters affecting local control after adjustment for clinical factors. Results: The 5-year actuarial local control was 77%. Factors associated with a decrease of local control in univariate analysis included: age less than 66 years (67% vs 85%), male gender (65% vs 81%), tumor extension more than (1(3)) circumference of the anal canal (68% vs 90%), lymph node involvement (64% vs 81%), use of external irradiation for the boost (62% vs 79%), and overall treatment time more than 74 days (69% vs 85%). In a multivariate analysis none of the therapeutic parameters remained significant when adjusted for the four significant clinical factors. The only therapeutic factor which might have had an impact was overall treatment time (p = .09

    2016-06-01

    Research on a model Therapeutic Workplace has allowed for evaluation of the use of employment in the treatment of drug addiction. Under the Therapeutic Workplace intervention, adults with histories of drug addiction are hired and paid to work. To promote drug abstinence or adherence to addiction medications, participants are required to provide drug-free urine samples or take prescribed addiction medications, respectively, to gain access to the workplace and/or to maintain their maximum rate of pay. Research has shown that the Therapeutic Workplace intervention is effective in promoting and maintaining abstinence from heroin, cocaine and alcohol and in promoting adherence to naltrexone. Three models could be used to implement and maintain employment-based reinforcement in the treatment of drug addiction: A Social Business model, a Cooperative Employer model, and a Wage Supplement model. Under all models, participants initiate abstinence in a training and abstinence initiation phase (Phase 1). Under the Social Business model, Phase 1 graduates are hired as employees in a social business and required to maintain abstinence to maintain employment and/or maximum pay. Under the Cooperative Employer model, cooperating community employers hire graduates of Phase 1 and require them to maintain abstinence to maintain employment and/or maximum pay. Under the Wage Supplement Model, graduates of Phase 1 are offered abstinence-contingent wage supplements if they maintain competitive employment in a community job. Given the severity and persistence of the problem of drug addiction and the lack of treatments that can produce lasting effects, continued development of the Therapeutic Workplace is warranted.

    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)

    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.

    Eight Japanese adult patients infected with Taenia asiatica were treated with a single 600 mg dose of praziquantel. The patients' body weights ranged from 47 to 87 kg (mean 67.1±12.7 kg). All patients expelled the strobila after taking praziquantel, and all of them were free from proglottids the day after praziquantel administration, hence all patients were considered to be cured. No side effects due to praziquantel were noted. Although the number of patients is small, our results indicate that praziquantel is a drug of choice for the treatment of taeniasis asiatica and that a single dose of 7-13 mg/kg (9.3±1.9 mg/kg) is effective.

    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.

    Effectiveness of an ultrasound treatment shall be assessed by experiments. A reliable cell culture protocol is available and spatial discrepancies could arise. To assure if the spatial difference are relevant or not, and how they should be dealt with, an uncertainty model for the treatment result is a metrological reliable solution. The present work reports a metrological approach to assess myotube thickness and to validate a primary cell culture of muscle after a therapeutic ultrasound treatment, comparing it with a control group. The results reinforced the importance of such approach and show an efficacy of treatment on myotube differentiation

    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.

    Full Text Available Introduction. Epidermal growth factor receptor (EGFR mutations are known as oncogene driver mutations and with EGFR mutations exhibit good response to the EGFR tyrosine kinase inhibitor Gefitinib. Some studies have shown that activation of estrogen and estrogen receptor α or β (ERα/β promote adenocarcinoma. We evaluated the relationship between the two receptors and the potential therapeutic benefit with Gefitinib and Tamoxifen. Methods. We assessed the association between EGFR mutations as well as ERα/β expression/location and overall survival in a cohort of 55 patients with LAC from a single hospital. PC9 (EGFR exon 19 deletion mutant; Gefitinib-vulnerable cells and A549 (EGFR wild type; Gefitinib-resistant cells cancer cells were used to evaluate the in vitro therapeutic benefits of combining Gefitinib and Tamoxifen. Results. We found that the cytosolic but not the nuclear expression of ERβ was associated with better OS in LAC tumors but not associated with EGFR mutation. The in vitro study showed that combined Gefitinib and Tamoxifen resulted in increased apoptosis and cytosolic expression of ERβ. In addition, combining both medications resulted in reduced cell growth and increased the cytotoxic effect of Gefitinib. Conclusion. Tamoxifen enhanced advanced LAC cytotoxic effect induced by Gefitinib by arresting ERβ in cytosol.

    BAFF, a member of the TNF superfamily, has been recognized as a good target for autoimmune diseases. Belimumab, an anti-BAFF monoclonal antibody, was approved by the FDA for use in treating systemic lupus erythematosus. However, the molecular basis of BAFF neutralization by belimumab remains unclear. Here our crystal structure of the BAFF-belimumab Fab complex shows the precise epitope and the BAFF-neutralizing mechanism of belimumab, and demonstrates that the therapeutic activity of belimumab involves not only antagonizing the BAFF-receptor interaction, but also disrupting the formation of the more active BAFF 60-mer to favor the induction of the less active BAFF trimer through interaction with the flap region of BAFF. In addition, the belimumab HCDR3 loop mimics the DxL(V/L) motif of BAFF receptors, thereby binding to BAFF in a similar manner as endogenous BAFF receptors. Our data thus provides insights for the design of new drugs targeting BAFF for the treatment of autoimmune diseases.

    2013-01-01

    The potential of bacteriophage therapy to treat infections caused by antibiotic-resistant bacteria has now been well established using various animal models. While numerous newly isolated bacteriophages have been claimed to be potential therapeutic candidates on the basis of in vitro observations, the parameters used to guide their choice among billions of available bacteriophages are still not clearly defined. We made use of a mouse lung infection model and a bioluminescent strain of Pseudomonas aeruginosa to compare the activities in vitro and in vivo of a set of nine different bacteriophages (PAK_P1, PAK_P2, PAK_P3, PAK_P4, PAK_P5, CHA_P1, LBL3, LUZ19, and PhiKZ). For seven bacteriophages, a good correlation was found between in vitro and in vivo activity. While the remaining two bacteriophages were active in vitro, they were not sufficiently active in vivo under similar conditions to rescue infected animals. Based on the bioluminescence recorded at 2 and 8 h postinfection, we also define for the first time a reliable index to predict treatment efficacy. Our results showed that the bacteriophages isolated directly on the targeted host were the most efficient in vivo, supporting a personalized approach favoring an optimal treatment. PMID:24041900

    The term metacognition reflects a spectrum of psychological activities that allows people to form and integrate representations about their own mental states and those of others. The main goal of this study was to examine whether people with substance abuse disorders (SUDs), and treated in therapeutic community regime, displayed specific patterns of metacognitive deficits on Self-reflectivity, Understanding others’ mind, Decentration, and Mastery, comparing their scores with two clinical groups of patients with schizophrenia spectrum disorders (SSDs) and anxiety disorders. A mixed-methods (qualitative-quantitative) study was designed. Two hundred and sixteen adults aged 18-65 with principal diagnoses of SUDs (n = 52), SSDs (n = 49), and anxiety disorders (n = 115) were recruited. Qualitative data were obtained with the Metacognition Assessment Interview, which was then rated using a quantitative scale, the Metacognition Assessment Scale-Abbreviated (MAS-A). The anxiety disorders group had significantly higher MAS-A total scores than the SUDs group, and the SUDs group obtained significantly higher MAS-A total scores than the SSDs group. Concerning the MAS-A subscale scores, the SUDs group displayed significantly lower scores only on the Mastery subscale compared to the anxiety disorders group, with the SUDs and SSDs groups obtaining equivalent Mastery scores. According to these findings, current interventions for addiction should focus more specifically on improving metacognitive Mastery.

    Klebsiella pneumoniae causes infections in humans especially in immunocompromised patients. About 80 % of nosocomial infections caused by K. pneumoniae are due to multidrug-resistant strains. The emergence of antibiotic-resistant bacterial strains necessitates the exploration of alternative antibacterial therapies, which led our group to study the ability of bacterial viruses (known as bacteriophages or simply phages) to treat mice challenged with K. pneumoniae. Phage SS specific for K. pneumoniae B5055 was isolated and characterized, and its potential as a therapeutic agent was evaluated in an experimental model of K. pneumoniae-mediated lobar pneumonia in mice. Mice were challenged by intranasal (i.n.) inoculation with bacteria (10(8) c.f.u. ml(-1)). A single intraperitoneal injection of 10(10) p.f.u. ml(-1) phage administered immediately after i.n. challenge was sufficient to rescue 100 % of animals from K. pneumoniae-mediated respiratory infections. Administration of the phage preparation 3 h prior to i.n. bacterial challenge provided significant protection in infected mice, while even 6 h delay of phage administration after the induction of infection rendered the phage treatment ineffective. The results of this study therefore suggest that the timing of starting the phage therapy after initiation of infection significantly contributes towards the success of the treatment.

    Sometimes the visitors to therapeutic gardens do not necessarily experience the garden the way the designers intended. A postoccupancy evaluation (POE) can reveal discrepancies between the designer's intentions and use of the environment by the actual visitors. A POE is a user-oriented assessment that elicits the opinions of the visitors to a building, facility, or environment. This paper describes a POE of therapeutic gardens at a multilevel care facility for the aged. The population included patients at various stages of Alzheimer's disease progression.

    Non-steroidal anti-inflammatory drugs (NSAIDs) and antioxidant therapy might protect against the development of Alzheimer's disease (AD). In the present work, we synthesized a molecular combination of glutathione (GSH) and ibuprofen (IBU) via an amide bond and investigated its potential for targeted delivery of the parent drugs to neurons, where cellular oxidative stress and inflammation are related to AD. Evaluation of its physicochemical and in-vitro antioxidant properties indicated that compound 1 exhibits good stability toward human plasma enzymatic activity, and, like GSH, displays in-vitro free radical scavenging activity in a time and concentration-dependent manner. The new compound was also assessed by infusion in a rat model for Alzheimer's disease for its potential to antagonize the deleterious structural and cognitive effects of β-amyloid(1-40). In behavioral tests of long-term spatial memory, animals treated with codrug 1 performed significantly better than those treated with β-amyloid (Aβ) peptide. Histochemical findings confirmed the behavioral data, revealing that Aβ protein was less expressed in cerebral cortex treated with 1 than that treated with IBU. Taken together, the present findings suggest that conjugate 1 treatment may protect against the oxidative stress generated by reactive oxygen species (ROS) and the cognitive dysfunction induced by intracerebroventricular (i.c.v.) infusion of Aβ(1-40) in rats, and thus that codrug 1 could prove useful as a tool for controlling AD induced cerebral amyloid deposits and behavioral deterioration.

    Rupture of the Achilles tendon diminishes quality of life. The gold-standard therapy is a surgical suture, but this presents complications, including wound formation and inflammation. These complications spurred evaluation of the therapeutic potential of mesenchymal stem cells (MSCs) from adipose tissue. New Zealand rabbits were divided into 6 groups (three treatments with two time points each) evaluated at either 14 or 28 days after surgery: cross section of the Achilles tendon (CSAT); CSAT + Suture; and CSAT + MSC. A comparison between all groups at both time points showed a statistically significant increase in capillaries and in the structural organization of collagen in the healed tendon in the CSAT + Suture and CSAT + MSC groups at the 14-day assessment. Comparison between the two time points within the same group showed a statistically significant decrease in the inflammatory process and an increase in the structural organization of collagen in the CSAT and CSAT + MSC groups. A study of the genomic integrity of the cells suggested a linear correlation between an increase of injuries and culture time. Thus, MSC transplantation is a good alternative for treatment of Achilles tendon ruptures because it may be conducted without surgery and tendon suture and, therefore, has no risk of adverse effects resulting from the surgical wound or inflammation caused by nonabsorbable sutures. Furthermore, this alternative treatment exhibits a better capacity for wound healing and maintaining the original tendon architecture, depending on the arrangement of the collagen fibers, and has important therapeutic potential.

    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.

    Full Text Available Inflammation and fibrosis are essential promoters in the pathogenesis of diabetic nephropathy (DN in type 2 diabetes. The present study examined the anti-inflammation and anti-fibrosis effect of Tangshen Formula (TSF, a traditional Chinese medicine, on DN.Protective role of TSF in DN was examined in a rat model of type 2 DN that was established by high-fat diet-fed and low-dose-streptozotocin injection. TSF was suspended in 0.5% CMC-Na solution and delivered by oral gavage at a dosage of 1.67g/Kg body weight/day. The therapeutic effects and mechanisms of TSF on diabetic kidney injury were examined.We found that TSF treatment for 20 weeks attenuated DN by significantly inhibiting urinary excretion of albumin and renal histological injuries. These beneficial effects were associated with an inactivation of NF-κB signaling, thereby blocking the upregulation of pro-inflammatory cytokines (IL-1β, TNFα, chemokine (MCP-1, and macrophage infiltration in the TSF-treated rats with type 2 DN. In addition, TSF treatment also inactivated TGF-β/Smad3 signaling and therefore suppressed renal fibrosis including expressions of fibronectin, collagen I, and collagen IV. Further studies revealed that the inhibitory effect of TSF on TGF-β/Smad3 and NF-κB signaling in DN was associated with inhibition of Smurf2-dependent ubiquitin degradation of Smad7.The present study reveals that TSF has therapeutic potential for type 2 DN in rats. Blockade of NF-κB-driven renal inflammation and TGF-β/Smad3-mediated renal fibrosis by preventing the Smurf2-mediated Smad7 degradation pathway may be mechanisms through which TSF inhibits type 2 DN.

    2017-09-01

    New therapies are needed to control bleeding in a range of clinical conditions. This review will discuss the biochemical properties of zymogen-like factor Xa, its preclinical assessment in different model systems, and future development prospects. Underlying many procoagulant therapeutic approaches is the rapid generation of thrombin to promote robust clot formation. Clinically tested prohemostatic agents (e.g., factor VIIa) can provide effective hemostasis to mitigate bleeding in hemophilia and other clinical situations. Over the past decade, we explored the possibility of using zymogen-like factor Xa variants to rapidly improve clot formation for the treatment of bleeding conditions. Compared to the wild-type enzyme, these variants adopt an altered, low activity, conformation which enables them to resist plasma protease inhibitors. However, zymogen-like factor Xa variants are conformationally dynamic and ligands such as its cofactor, factor Va, stabilize the molecule rescuing procoagulant activity. At the site of vascular injury, the variants in the presence of factor Va serve as effective prohemostatic agents. Preclinical data support their use to stop bleeding in a variety of clinical settings. Phase 1 studies suggest that zymogen-like factor Xa is safe and well tolerated, and a phase 1b is ongoing to assess safety in patients with intracerebral hemorrhage. Zymogen-like factor Xa is a unique prohemostatic agent for the treatment of a range of bleeding conditions.

    To observe the curative effects of rh-endostatin combined with DP regimen in treating patients with advanced esophageal cancer and analyze the correlation of CT perfusion (CTP) parameters and the expression of vascular endothelial growth factor (VEGF). Twenty patients with esophageal cancer confirmed pathologically were randomly divided into combined treatment (rh-endostatin+DP regimen) group and single chemotherapy group, 10 patients in each group, respectively. All patients were given conventional CT examination and CTP imaging for primary tumor. The level of VEGF, the size of tumor and CTP parameters (BF, BV, PS and MTT) before treatment and after 2 cycles of treatment were determined for the comparison and the correlation between CTP parameters and VEGF expression was analyzed. the therapeutic effect of rh-endostatin+DP regimen group was superior to single chemotherapy group. VEGF level after treatment in rh- endostatin +DP regimen group was obviously lower than single chemotherapy group (Prh-endostatin +DP regimen group, BF, BV and PS decreased while MTT increased after treatment (P0.05). Rh-endostatin can down-regulate the expression of VEGF in esophageal cancer, change the state of hypertransfusion and high permeability of tumor vessels and had the better curative effect and slighter adverse reactions when combined with chemotherapy.

    According to the Brazilian Consensus on Paracoccidioidomycosis (PCM), itraconazole is the drug of choice for treatment. However, the combination of sulfamethoxazole and trimethoprim (SMX-TMP) is most commonly used in clinical practice because of its higher availability in the public health services. The aims of this study were to evaluate the therapeutic response of patients with nonsevere chronic PCM to SMX-TMP and highlight the factors related to treatment failure. An adequate therapeutic response was defined as completely improved disease signs and symptoms after medication use for a minimum of 6 months, followed by normalized hematological and biochemical changes, radiological improvements, and negative mycological examination findings. Medical records were analyzed for 244 patients with nonsevere chronic PCM who were treated between 1998 and 2014. In total, 41.9% of the patients had PCM for ≥ 8 months. Seven (2.9%) patients were coinfected with human immunodeficiency virus (HIV). The median (25%, 75% percentiles) treatment duration was 21 (10, 25) months. Adequate treatment adherence was reported by 68.3% of patients. In addition, 73.6% of patients exhibited an adequate therapeutic response. The majority (82.6%) of patients who were treated with SMX-TMP for > 24 months displayed an adequate therapeutic response, and the frequency of adequate therapeutic response gradually decreased as the duration of treatment decreased. Treatment nonadherence ( P < 0.001) and PCM-HIV coinfection ( P = 0.019) were factors associated with therapeutic failure. The study results support the good efficacy of SMX-TMP. Attention should be given to PCM-HIV coinfection, emphasizing the concern of a higher risk of PCM therapeutic failure in these patients.

    Pancreatic cancer (PC) is the fourth leading cause of cancer related-deaths in both men and women, and the 1- and 5-year relative survival rates are 25% and 6%, respectively. It is known that smoking, alcoholism and psychological stress are risk factors that can promote PC and increase PC progression. To date, the prevention of PC is crucial because there is no curative treatment. After binding to the neurokinin-1 (NK-1) receptor (a receptor coupled to the stimulatory G-protein Gαs that activates adenylate cyclase), the peptide substance P (SP)—at high concentrations—is involved in many pathophysiological functions, such as depression, smoking, alcoholism, chronic inflammation and cancer. It is known that PC cells and samples express NK-1 receptors; that the NK-1 receptor is overexpressed in PC cells in comparison with non-tumor cells, and that nanomolar concentrations of SP induce PC cell proliferation. By contrast, NK-1 receptor antagonists exert antidepressive, anxiolytic and anti-inflammatory effects and anti-alcohol addiction. These antagonists also exert an antitumor action since in vitro they inhibit PC cell proliferation (PC cells death by apoptosis), and in a xenograft PC mouse model they exert both antitumor and anti-angiogenic actions. NK-1 receptor antagonists could be used for the treatment of PC and hence the NK-1 receptor could be a new promising therapeutic target in PC

    2015-01-01

    Statins competitively inhibit hepatic 3-hydroxy-3-methylglutaryl-coenzyme A reductase, resulting in reduced plasma total and low-density lipoprotein cholesterol levels. Recently, it has been shown that statins exert additional ‘pleiotropic’ effects by increasing expression levels of the membrane water channels aquaporin 2 (AQP2). AQP2 is localized mainly in the kidney and plays a critical role in determining cellular water content. This additional effect is independent of cholesterol homoeostasis, and depends on depletion of mevalonate-derived intermediates of sterol synthetic pathways, i.e. farnesylpyrophosphate and geranylgeranylpyrophosphate. By up-regulating the expression levels of AQP2, statins increase water reabsorption by the kidney, thus opening up a new avenue in treating patients with nephrogenic diabetes insipidus (NDI), a hereditary disease that yet lacks high-powered and limited side effects therapy. Aspects related to water balance determined by AQP2 in the kidney, as well as standard and novel therapeutic strategies of NDI are discussed. PMID:25594563

  10. Effectiveness testing of spill-treating agents

    1990-01-01

    Laboratory effectiveness tests are described for four classes of spill-treating agents: solidifiers, demulsifying agents, surface-washing agents and dispersants. Many treating agents in these four categories have been tested for effectiveness and the results are presented. Solidifiers or gelling agents solidify oil, requiring a large amount of agent to solidify oil-ranging between 16% by weight, to over 200%. Emulsion breakers prevent or reverse the formation of water-in-oil emulsions. A newly-developed effectiveness test shows that only one product is highly effective; however, many products will work, but require large amounts of spill-treating agent. Surfactant--containing materials are of two types, surface-washing agents and dispersants. Testing has shown that an agent that is a good dispersant is conversely a poor surface-washing agent, and vice versa. Tests of surface-washing agents show that only a few agents have effectiveness of 25-40%, where this effectiveness is the percentage of heavy oil removed from a test surface. Results using the 'swirling flask' test for dispersant effectiveness are reported. Heavy oils show effectiveness values of about 1%, medium crudes of about 10%, light crude oils of about 30% and very light oils of about 90%. (author)

    , our results showed that CIO exhibit two distinct antibacterial effects: one against Gram+ bacteria by direct inhibition of mitotic growth and another potent effect against Gram- bacteria due to increased release of β-defensin 2 peptide by macrophages. Interestingly, the needed concentrations of CIO to inhibit bacteria growth and to promote wound healing are lower than concentrations exhibiting cytotoxic effects on keratinocyte cells. Finally, we performed bioautography assay against Staphylococcus aureus to determine polarity profile of the components responsible for CIO antibacterial activity. Our results showed for the five tested CIO that components responsible of the bacterial growth inhibition are the more polar one on the TLC chromatographic profile and are contained in the resinous fraction of the oil. Conclusions This study was conducted to evaluate cytotoxicity, wound healing and antibacterial properties of five CIO traditionally used to treat infected wounds. Using cell and bacteria cultures, we confirmed the pharmacological effects of CIO as wound healing and antimicrobial agent. Moreover, we showed that concentration of CIO needed to exhibit therapeutic effects are lower than concentrations exhibiting cytotoxic effects in vitro. For the first time, this study provides support for traditional uses of CIO. These wound healing and antibiotic properties make CIO a valuable candidate to treat infected wounds especially in tropical areas. PMID:26406588

    -step procedure that includes skin suction using cups, scarification (shartat mihjam in Arabic), and second skin suction (triple S technique). Al-hijamah is a more comprehensive technique and does better than traditional WCT, as Al-hijamah includes two pressure-dependent filtration steps versus one step in traditional WCT. Whenever blood plasma is to be cleared of an excess pathological substance, Al-hijamah is indicated. We will discuss here some reported hematological and therapeutic benefits of Al-hijamah, its medical bases, methodologies, precautions, side effects, contraindications, quantitative evaluation, malpractice, combination with oral honey treatment, and to what extent it may be helpful when treating thalassemia and other conditions of iron overload and hyperferremia.

    The aim of this study was to analyze the relationship between the partial pressure of arterial oxygen (PaO2) and in-hospital (IH) mortality in children after cardiac arrest (CA) using the conventional cutoff analysis, which was compared with the cumulative analysis, a new method in PaO2 analysis. Additionally, we analyzed this relationship for children with and without mild therapeutic hypothermia (MTH; 32-34 °C). This observational cohort study included all children (aged >28 days) with CA and return of spontaneous circulation (ROSC) between 2002 and 2011. The first research question was the association between PaO2 and IH mortality after ROSC. This was analyzed for three hyperoxia cutoff values, and for three time intervals using the cumulative PaO2 determined with the area under the curve (AUC). For the second research question, these analyses were repeated for children with and without MTH. Of the 200 patients included (median age 2.6 years), 84 (42%) survived to hospital discharge. Fifty-eight children (29%) were treated with MTH. With the cutoff analysis and the AUC analysis we found no relationship between PaO2 and IH mortality. However, analysis of the MTH-group showed a lower IH mortality in children with high cumulative PaO2 levels on two of the three time intervals. Multivariable analysis showed significantly higher odds of survival (0.643 (95% confidence interval (CI) 0.424-0.976), 0.554 (95% CI 0.335-0.916)). Cumulative PaO2 analysis showed that the IH mortality is significantly lower in MTH-treated children with high PaO2 levels. The effects of cumulative PaO2 on the outcome need to be studied further, and this will help us to achieve individualized goal-directed therapy. Copyright © 2015 Elsevier Ireland Ltd.

    Lichen amyloidosis is a primary localized cutaneous amyloidosis. Different types of treatment have been used without complete resolution. Herein, we report a case of patient suffering from lichen amyloidosis successfully treated with fractional ablative laser CO 2 . He was a 59-year-old man diagnosed lichen amyloidosis localized on the legs 10 years ago. He was treated with topical corticosteroids without any improvement. Then, we started treating the affected area with CO 2 laser (limmer*) at a setting of 5-8 J/cm 2 and 8 mm laser spot size. A considerable improvement was noticed after the first session. A total healing was reported after four sessions. To the best of our knowledge, only 11 reported cases of lichen amyloidosis have been successfully treated with laser CO 2 . However, our clinical finding seems to be one of the best reported results.

    In spas with a somewhat elevated Radon{sup 222} (Rn) activity (between 300 and 3000 Bq/l), the empirical medicine ended - in all parts of the world - with the same list of indications. It mainly includes the more painful rheumatic diseases such as deformation or degeneration of the joints and non bacterial inflammation of muscles, tendons or joints; Morbus Bechterew and other diseases of the vertebral column like spondylosis, spondylarthrosis or osteochondrosis. While informer times these effects were seldom documented in an objective manner, in recent years several prospective randomized double-blind studies proved the pain reducing efficacy of Radon therapy in patients with cervical pain syndromes, with chronic polyarthritis or with Morbus Bechterew. Studies in experimental animal models have accumulated remarkable data in organs, tissue and cultured cells that provide a rationale to explain the observed effects of Radon therapy in patients.

    The Thompson encephalopathy score is a clinical score to assess newborns suffering from perinatal asphyxia. Previous studies revealed a high sensitivity and specificity of the Thompson encephalopathy score for adverse outcomes (death or severe disability). Because the Thompson encephalopathy score was developed before the use of therapeutic hypothermia, its value was reassessed. The purpose of this study was to assess the association of the Thompson encephalopathy score with adverse short-term outcomes, defined as death before discharge, development of severe epilepsy, or the presence of multiple organ failure in asphyxiated newborns undergoing therapeutic hypothermia. The study period ranged from November 2010 to October 2014. A total of 12 tertiary neonatal intensive care units participated. Demographic and clinical data were collected from the "PharmaCool" multicenter study, an observational cohort study analyzing pharmacokinetics of medication during therapeutic hypothermia. With multiple logistic regression analyses the association of the Thompson encephalopathy scores with outcomes was studied. Data of 142 newborns were analyzed (male: 86; female: 56). Median Thompson score was 9 (interquartile range: 8 to 12). Median gestational age was 40 weeks (interquartile range 38 to 41), mean birth weight was 3362 grams (standard deviation: 605). All newborns manifested perinatal asphyxia and underwent therapeutic hypothermia. Death before discharge occurred in 23.9% and severe epilepsy in 21.1% of the cases. In total, 59.2% of the patients had multiple organ failure. The Thompson encephalopathy score was not associated with multiple organ failure, but a Thompson encephalopathy score ≥12 was associated with death before discharge (odds ratio: 3.9; confidence interval: 1.3 to 11.2) and with development of severe epilepsy (odds ratio: 8.4; confidence interval: 2.5 to 27.8). The Thompson encephalopathy score is a useful clinical tool, even in cooled asphyxiated

    To assess the frequency of osteosclerotic changes on CT that appeared after treatment with gefitinib in patients with lung adenocarcinoma and the relationship between the osteosclerotic changes and the response to the therapy. Our study included 41 patients with lung adenocarcinoma who underwent chest CT both before (CTpre) and after (CTpost) starting treatment with gefitinib. The presence or absence of bone metastases was assessed on the CTpre, and the interval bony change after the therapy was classified as lytic, sclerotic, or no changes on the CTpost. The relationship between treatment results of primary lung cancer and interval bony changes was evaluated. Osteosclerotic lesions were identified in 11 patients (27%) on CTpost; in 6 of 11 patients osteosclerotic lesions newly appeared where the CTpre showed no bone metastasis before the gefitinib therapy. There were significant differences in the therapeutic response of the primary cancers (P < 0.001) and in the survival rate (P < 0.01) in patients with osteosclerotic changes versus those without osteosclerotic changes. Osteosclerotic changes on CT, observed after gefitinib treatment in patients with lung adenocarcinomas, may be an indicator of a good therapeutic response. (orig.)

    Full Text Available Background: The outpatient therapeutic care program (OTP of children with severe acute malnutrition (SAM has been decentralized to health post level in Ethiopia since 2008–2009. However, there is a lack of evidence regarding treatment outcomes and factors related to the duration of stay on treatment after its decentralization to health post level. Objective: This study was aimed to assess treatment outcome and factors affecting time to recovery in children with SAM treated at OTP. Design: Health facility–based retrospective cohort study was conducted using data from 348 patient cards. The outcome variable was time to recovery. Descriptive analysis was done using percentages for categorical data and mean/median for continuous variables. A robust method of analyzing time to event data, the Cox proportional-hazard regression, was used. All statistical tests in this study are declared significant at p<0.05. Result: 89.1% of children with kwashiorkor and 69.4% of children with marasmus were recovered. Of the total children studied, 22% were readmitted cases. The median time of recovery was 35 days for children with kwashiorkor and 49 days for children with marasmus. Children older than 3 years were 33% less likely to achieve nutritional recovery [adjusted hazard ratio, AHR=0.67, 95% confidence interval, CI (0.46, 0.97]. Similarly, marasmic children stayed longer on treatment [AHR=0.42, 95% CI (0.32, 0.56]. However, children who gained Mid-Upper Arm Circumference (MUAC ≥ 0.24 mm/day were 59% more likely to recover faster [AHR=1.59, 95% CI (1.23, 2.06]. Conclusions: Close monitoring of weight and MUAC gain to assess nutritional improvement with due emphasis given to children with lower admission weight, children of age 3 years and above and marasmic children will have a positive effect on treatment duration and outcome.

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

    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.

    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.

    Wistar rats were divided into seven groups: the normal group, the irradiated group, the preventive group treated with the normal dose of compound white peony root oral liquids (cWPROL) (immediately administered on the day after rats were irradiated), the preventive group treated with the high dose of cWPROL (immediately administered on the day after rats were irradiated), the group treated with normal dose of cWPROL (administered on the 7th day after rats were irradiated), the group treated with high dose of cWPROL (administered on the 7th day after rats were irradiated), the group treated with Western medicine administered from the seventh day after irradiation. The radiation esophagitis of rats was induced by single irradiation of 43 Gy gamma ray locally. Then the rats with radiation esophagitis were treated in different ways. The food weight, water volume intaked by the rats and its body weight change were observed; The rats were killed on the 14th day after irradiation and the leucocyte count and DIFF were analyzed and the esophageal pathological sections were made. The pathological change of rats' esophageal mucosa and ultrastructure change of cells were observed for different groups. The results showed all the cWPROL and Western medicine have therapeutic function of treating radiation-induced esophagitis of rats. The ultrastructure of cells of rats in the group treated with normal dose of cWPROL recovered. The food weight and water volume intaked by the rats had increased in the group infused with cWPROL compared with purely irradiated groups, especially in the preventive group treated with high dose of cWPROL. The weight of food, the WBC count, the lymphocyte differential count in the group which was treated with Western medicine decreased compared with the purely irradiated group. Lymphocyte differential count increased in the groups administered cWPROL compared with the purely irradiated group. The compound white peony root oral liquids serves the function

    Full Text Available Until recently, multiple sclerosis has been viewed as an entirely inflammatory disease without acknowledgment of the significant neurodegenerative component responsible for disease progression and disability. This perspective is being challenged by observations of a dissociation between inflammation and neurodegeneration where the neurodegenerative component may play a more significant role in disease progression. In this review, we explore the relationship between mitochondrial dysfunction and neurodegeneration in multiple sclerosis. We review evidence that the ketogenic diet can improve mitochondrial function and discuss the potential of the ketogenic diet in treating progressive multiple sclerosis for which no treatment currently exists.

    Full Text Available Protein phosphatase 2A (PP2A is a tumor suppressor complex that has recently been reported as a novel and highly relevant molecular target in prostate cancer (PCa. However, its potential therapeutic value remains to be fully clarified. We treated PC-3 and LNCaP cell lines with the PP2A activators forskolin and FTY720 alone or combined with the PP2A inhibitor okadaic acid. We examined PP2A activity, cell growth, prostasphere formation, levels of PP2A phosphorylation, CIP2A and SET expression, and AKT and ERK activation. Interestingly, both forskolin and FTY720 dephosphorylated and activated PP2A, impairing proliferation and prostasphere formation and inducing changes in AKT and ERK phosphorylation. Moreover, FTY720 led to reduced CIP2A levels. Treatment with okadaic acid impaired PP2A activation thus demonstrating the antitumoral PP2A-dependent mechanism of action of both forskolin and FTY720. Levels of PP2A phosphorylation together with SET and CIP2A protein expression were studied in 24 PCa patients and both were associated with high Gleason scores and presence of metastatic disease. Altogether, our results suggest that PP2A inhibition could be involved in PCa progression, and the use of PP2A-activating drugs might represent a novel alternative therapeutic strategy for treating PCa patients.

    Fluorescent compounds had gained strong attention due to their wide and appealing applications. Microscopic techniques and visualization are good examples among others. Introduction of fluorescent dyes into microbiology opens the possibility to observe tissues, organisms or organelle with exceptional sensitivity and resolution. Probes for detection of biologically relevant metals as zinc, iron or copper seems to be particularly important for drug design and pharmaceutical sciences. Quinoline derivatives are well known for their good metal affinity and wide spectrum of biological activity. In this regard, molecular sensors built on this scaffold may be useful not only as analytical but also as therapeutic agents. In the present review, application of quinoline moiety in designing of novel fluorescent probes for zinc is presented and discussed. Zinc cations are relevant for vast majority of processes and recently attract a great deal of attention for their role in neurodegenerative diseases. Compounds interacting with Zn2+ may be used for early diagnosis of such disorders, for example the Alzheimer disease. Quinoline-based zinc probes may exert some beneficial role in organism acting as theranostic agents. First preliminary drugs for Alzheimer therapy that are based on quinoline moiety are good example of this trend.

    The therapeutic outcome of chemotherapy in NK/T cell lymphoma (NTCL) has not been well documented until now. The aims of this study were to investigate the outcome of chemotherapy and to evaluate the clinical factors influencing the responsiveness to chemotherapy. Between 1995 and 2000, 59 patients received anthracycline-based chemotherapy as an initial treatment. Forty-five patients had nasal NTCL, whereas 14 had extranasal NTCL. Forty-one patients had stage I/II and 18 had stage III/IV disease. Epstein-Barr virus status was positive in 67.6% of cases. The results of initial chemotherapy were complete remission in 35.6% of the patients, 2-year disease-free survival in 22.9% and 2-year overall survival in 44.2%. Adjuvant radiotherapy after chemotherapy did not improve outcome in stage I/II nasal NTCL. The International Prognostic Index was a significant prognostic factor of complete remission rate, and stage was also significant for disease-free survival.

    Vibrio harveyi is amongst the most important bacterial pathogens in aquaculture. Novel methods to control this pathogen are needed since many strains have acquired resistance to antibiotics. We previously showed that quorum sensing-disrupting furanones are able to protect brine shrimp larvae against vibriosis. However, a major problem of these compounds is that they are toxic toward higher organisms and therefore, they are not safe to be used in aquaculture. The synthesis of brominated thiophenones, sulphur analogues of the quorum sensing-disrupting furanones, has recently been reported. In the present study, we report that these compounds block quorum sensing in V. harveyi at concentrations in the low micromolar range. Bioluminescence experiments with V. harveyi quorum sensing mutants and a fluorescence anisotropy assay indicated that the compounds disrupt quorum sensing in this bacterium by decreasing the ability of the quorum sensing master regulator LuxR to bind to its target promoter DNA. In vivo challenge tests with gnotobiotic brine shrimp larvae showed that thiophenone compound TF310, (Z)-4-((5-(bromomethylene)-2-oxo-2,5-dihydrothiophen-3-yl)methoxy)-4-oxobutanoic acid, completely protected the larvae from V. harveyi BB120 when dosed to the culture water at 2.5 µM or more, whereas severe toxicity was only observed at 250 µM. This makes TF310 showing the highest therapeutic index of all quorum sensing-disrupting compounds tested thus far in our brine shrimp model system. PMID:22848604

    There are two different types of radiation energetic particles and electromagnetic waves. These two types can penetrate into living tissue or cell and result in transduction of radiation energy to biological materials. The absorbed energy of ionising radiation can break chemical bonds and cause ionization of different molecules including water and different biological essential macromolecules of as DNA, membrane lipids and protein. Many types of DNA lesions are produce in cell by ionizing radiation and chemicals during cancer therapy. Cadmium is known to deplete glutathione and protein bounds sulfhydrl groups which results in enhance production of reactive oxygen species (ROS). The reactions of these ROS with cellular biomolecules have been shown to lead to lipid per-oxidation. Aloe vera is dietary antioxidant that plays an important role in controlling oxidative stress. For this purpose, six to eight weeks old male Swiss albino mice (Mus musculus) were randomly divided into seven groups. On the basis of radiation, cadmium, combined treatment and Aloe treated groups the animals were sacrificed at each post treatment intervals of 1, 2, 4, 7, 14 and 28 days. The brain were taken out and weighed to the analytical balance and fixed for 24 hours in alcoholic Bouin's fixative. A pinch of lithium carbonate was added to remove excess picric acid in the fixative. Histological studies were carried out using the standard techniques of haematoxyline and eosin staining. After combined treatment of radiation and cadmium chloride synergistic changes were observed. These changes were less severe in the Aloe vera treated brain which may be due to the protection provided by drug

    We present a retrospective study of our paediatric patients affected by pilonidal disease over the last 5 years. In all cases a broad excision of the pilonidal tissue was made, without colour signing the different incision sites and primary closure of the defect with no drainage. Using this technique we treated 20 adolescents (15 girls and 5 boys) of ages between 12 and 15 years (average age 13.3 years) and body mass index between 17 and 33 (mean BMI 26.4 kg/m2). Mean hospitalisation time was 1.45 days. Preoperative antibiotherapy with Amoxicillin-clavulanic was administered to 55% of patients and continued over the first postoperative week. We had four cases with recurrence of the disease (25%) (two of these with two recurrences), which we treated with three primary closures on the midline and three by flattening the cleft. In 2 cases with dehiscence of the wound we allowed treatment by secondary intention. No flaps or marsupialisation were attempted in any case. In all cases the result was aesthetically satisfactory, with maintenance of the intergluteal fold. In our series we have succeeded in undertaking primary closure of the defect after pilonidal resection without any excessive tension. This treatment enables a rapid return to a normal routine. We considered it important to undertake surgery that maintained the intergluteal fold, especially in patients with a short-term evolution of the disease, reserving flattening the cleft, closure by secondary intention, or primary closure by inserting flaps only for cases of recurrent disease; those with long-term evolution; or patients with complex lesions prior to surgery. Nutritional support to reduce overweight is very important in many patients.

    Pathological changes and disorders of the cornea are a major cause of severe visual impairment and blindness. Replacement of a pathologically altered cornea with healthy corneal tissue from the eye of a suitable donor is among the most common and successful transplantation procedures in medicine. In Germany, approximately 5000-6000 corneal transplantations are performed each year, but the total demand per year is estimated to be twice as high. With a success rate of 90%, the outcome of cornea transplantation is very favourable. However, long-term maintenance and regeneration of a healthy new cornea requires tissue-specific corneal stem cells residing at the basal layer of the limbus, which is the annular transition zone between the cornea and sclera. When this important limbal stem cell population is destroyed or dysfunctional, a pathological condition known as limbal stem cell deficiency (LSCD) manifests. Limbal stem cell deficiency describes conditions associated with impaired corneal wound healing and regeneration. In this situation, transplantation of healthy limbal stem cells is the only curative treatment approach for restoration of an intact and functional ocular surface. To date, treatment of LSCD presents a great challenge for ophthalmologists. However, innovative, cell-therapeutic approaches may open new, promising treatment perspectives. In February 2015, the European Commission granted marketing authorization to the first stem cell-based treatment in the European Union. The product named Holoclar® is an advanced therapy medicinal product (ATMP) for the treatment of moderate to severe LSCD due to physical and chemical burns in adults. Further cell-based treatment approaches are in clinical development.

    Full Text Available Immunotherapy is considered to be the only curative treatment for allergic diseases such as pollinosis, perennial rhinitis, asthma, and food allergy. The sublingual route is widely applied for immunotherapy for allergy, instead of the conventional administration by subcutaneous route. A recent meta-analysis of sublingual immunotherapy (SLIT has shown that this approach is safe, has positive clinical effects, and provides prolonged therapeutic effects after discontinuation of treatment. However, the mechanism of SLIT and associated biomarkers are not fully understood. Biomarkers that change after or during SLIT have been reported and may be useful for response monitoring or as prognostic indicators for SLIT. In this review, we focus on the safety, therapeutic effects, including prolonged effects after treatment, and new methods of SLIT. We also discuss response monitoring and prognostic biomarkers for SLIT. Finally, we discuss immunological mechanisms of SLIT with a focus on oral dendritic cells and facilitated antigen presentation.

    Full text: Onychomycosis is the most frequent cause of nail disease and the most prevalent type of dermatophytosis in Bangladesh. The humid and warm climate of this tropical country is congenial for the growth of fungi. Therapeutic limitations of conventional antimycotic agents in respect of low cure rates, high relapse rate, inherent side effects, long duration of treatment and high cost in treating onychomycosis have provided clear incentives to explore alternative forms of treatment procedure. The objectives of the present thesis work were: (i) To use beta radiation as a curative therapy for Onychomycosis, optimisation of its dosages and to promote an innovative clinical development in the field of therapeutic application of nuclear medicine; (ii) To assess the efficacy of beta radiation either alone or in combination with conventional antifungal therapy; and (iii) To reduce the duration of drug exposure and cost of treatment for onychomycosis. This is a PhD research work under the University of Dhaka and was sponsored by the Ministry of Science and Information and Communication Technology, Government of the people's republic of Bangladesh. This study is an open, randomised and controlled trial to verify the efficacy of beta radiation in patients with onychomycosis. Using the appropriate statistical formula, sample size of the study population was determined and in each group 92 patients were assigned. With an assumption of patients drop out and for better statistical analysis, a total of 330 patients, who fulfilled the inclusion criterion having diagnosed to have onychomycosis clinically and mycological were randomly allocated to enter in therapeutic regimen. Study population was randomised in three groups. Group A (n =110) received griseofulvin orally 500 mg once daily for 12-16 weeks; Group B (n=110) received beta radiation, 500 rads bi-weekly for 3 weeks (total 2500 rads); and Group C (n=110) received combined beta radiation (total 2500 rads in 3 weeks) and

    Recent progress at the molecular level has revealed that nuclear receptors play an important role in the generation of mammalian circadian rhythms. To examine whether peroxisome proliferator-activated receptor alpha (PPARα) is involved in the regulation of circadian behavioral rhythms in mammals, we evaluated the locomotor activity of mice administered with the hypolipidemic PPARα ligand, bezafibrate. Circadian locomotor activity was phase-advanced about 3 h in mice given bezafibrate under light-dark (LD) conditions. Transfer from LD to constant darkness did not change the onset of activity in these mice, suggesting that bezafibrate advanced the phase of the endogenous clock. Surprisingly, bezafibrate also advanced the phase in mice with lesions of the suprachiasmatic nucleus (SCN; the central clock in mammals). The circadian expression of clock genes such as period2, BMAL1, and Rev-erbα was also phase-advanced in various tissues (cortex, liver, and fat) without affecting the SCN. Bezafibrate also phase-advanced the activity phase that is delayed in model mice with delayed sleep phase syndrome (DSPS) due to a Clock gene mutation. Our results indicated that PPARα is involved in circadian clock control independently of the SCN and that PPARα could be a potent target of drugs to treat circadian rhythm sleep disorders including DSPS

    Amenorrhea following spinal cord injury (SCI) has been well documented. There has been little research on the underlying molecular mechanisms and therapeutics. The purpose of the present study was to investigate the effect of GSNO in ameliorating SCI-induced amenorrhea through affecting the expression of CX43, NFkB, and ERβ protein. SCI was induced in female SD rats at the T9-T10 level. Estrous stage was determined by vaginal smear. GSNO (50 µg/kg body weight) was gavage fed daily. Animals were sacrificed on day 7 and 14 post SCI. Ovaries were fixed for histological and biochemical studies. Expression levels of ERβ, CX-43, and NFkB were analyzed by Western blot and immunofluorescence. GSNO hastens resumption of the estrous cycle following SCI-induced transient arrest. Resumption of estrous cycle was hastened by GSNO. Atretic and degenerating follicles seen in the ovary of SCI rats on day 14 post-SCI were decreased in GSNO treated animals. The increased CX43 expression observed with SCI ovary was decreased by GSNO. ERβ expression decreased significantly on day 7 and 14 post-SCI and was restored with GSNO treatment. Following SCI, NFkB expression was increased in the ovarian follicles and the expression was reduced with GSNO administration. The number of terminal deoxynucleotidyl transferase-mediated biotinylated uridine triphosphate (UTP) nick end labeling positive follicular and luteal cells was increased after SCI. GSNO-treated animals had significantly fewer apoptotic cells in the ovary. SCI-induced amenorrhea is accompanied by an increase in CX43 expression and a decrease in ERβ expression. SCI animals treated with GSNO resumed the estrous cycle significantly earlier. These results indicate a potential therapeutic value for GSNO in treating amenorrhea among SCI patients. © 2011 International Society for Sexual Medicine.

    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

    Background . Depression is a recurrent, common, and potentially life-threatening psychiatric disease related to multiple assignable causes. Although conventional antidepressant therapy can help relieve symptoms of depression and prevent relapse of the illness, complementary therapies are required due to disadvantage of the current therapy such as adverse effects. Moreover, a number of studies have researched adjunctive therapeutic approaches to improve outcomes for depression patients. Purpose . One potential complementary method with conventional antidepressants involves the use of medicinal herbs and phytochemicals that provide therapeutic benefits. Studies have revealed beneficial effects of medical herbs and phytochemicals on depression and their central nervous system mechanism. Here, we summarize the current knowledge of the therapeutic benefits of phytochemicals and medicinal herbs against depression and describe their detailed mechanisms. Sections . There are two sections, phytochemicals against depression and medical herbs against depression, in this review. Conclusion . Use of phytomedicine may be an alternative option for the treatment of depression in case conventional drugs are not applicable due to their side effects, low effectiveness, or inaccessibility. However, the efficacy and safety of these phytomedicine treatments for depression have to be supported by clinical studies.

    Background: Therapeutic hypothermia (TH) after out-of-hospital cardiac arrest (OHCA) is associated with adverse events, for example hypokalemia and arrhythmias. In the present study, we report the impact of serum potassium changes related to the rate of cardiac arrhythmias, and the advantages...... and disadvantages of potassium supplementation are discussed. Methods: Fifty-four consecutive patients suffering from OHCA and treated with TH (32-34°C) for 24 hours at one University Hospital were included and followed for 48 hours. Results: Serum potassium levels decreased during cooling from a median admission...... value of 4.0 mmol/L (quartiles 3.6-4.5 mmol/L) to a nadir of 3.6 mmol/L (3.5-3.9 mmol/L) 6 hours after target temperature (p=0.005), and 76% reached values of values of >5.5 mmol/L. Potassium supplementation was initiated at 3...

    Ultrasound elasticity imaging is a non-invasive technique developed to evaluate fibrosis. Measuring tissue strain by ultrasound elasticity imaging can reliably detect severe ileal fibrosis in patients with Crohn's disease [CD]. We have hypothesised that a more severe range of fibrosis might influence the therapeutic response to anti-tumour necrosis factor [TNF] treatment. The aim of this study was to assess the ability of ultrasound elasticity imaging to predict the therapeutic outcome for CD patients. Consecutive patients with ileal/ileocolonic CD, starting anti-TNF treatment, were enrolled for the study. These patients underwent bowel ultrasound and ultrasound elasticity imaging at baseline and at 14 and 52 weeks after anti-TNF treatment. Bowel wall stiffness was quantified by calculating the strain ratio between the mesenteric tissue and the bowel wall. Strain ratio ≥ 2 was used to identify severe ileal fibrosis. Transmural healing at 14 and 52 weeks was defined as bowel wall thickness ≤ 3 mm. Thirty patients with CD were enrolled. Five patients underwent surgery for bowel obstruction. The frequency of surgeries was significantly greater in patients with a strain ratio ≥ 2 at baseline [p = 0.003]. A significant reduction of the bowel thickness was observed after 14 and 52 weeks of anti-TNF treatment [p < 0.005]. A significant inverse correlation was observed between the strain ratio values at baseline and the thickness variations following anti-TNF therapy [p = 0.007]; 27% of patients achieved transmural healing at 14 weeks. The baseline strain ratio was significantly lower in patients with transmural healing [p < 0.05]. This study shows that ultrasound elasticity imaging predicts therapeutic outcomes for CD patients treated with anti-TNF. Copyright © 2017 European Crohn’s and Colitis Organisation (ECCO).

    Full Text Available Acute attacks of multiple sclerosis (MS are most commonly treated with glucocorticoids, which can provide life-saving albeit only temporary symptomatic relief. The mechanism of action (MOA is now known to involve induction of indoleamine 2,3-dioxygenase (IDO and interleukin-10 (IL-10, where IL-10 requires subsequent heme oxygenase-1 (HMOX-1 induction. Ectopic expression studies reveal that even small changes in expression of IDO, HMOX-1, or mitochondrial superoxide dismutase (SOD2 can prevent demyelination in experimental autoimmune encephalomyelitis (EAE animal models of MS. An alternative to glucocorticoids is needed for a long-term treatment of MS. A distinctly short list of endogenous activators of both membrane G-protein-coupled receptors and nuclear peroxisome proliferating antigen receptors (PPARs demonstrably ameliorate EAE pathogenesis by MOAs resembling that of glucocorticoids. These dual activators and potential MS therapeutics include endocannabinoids and the prostaglandin 15-deoxy-Δ12,14-PGJ2. Nicotinamide profoundly ameliorates and prevents autoimmune-mediated demyelination in EAE via maintaining levels of nicotinamide adenine dinucleotide (NAD, without activating PPAR nor any G-protein-coupled receptor. By comparison, nicotinic acid provides even greater levels of NAD than nicotinamide in many tissues, while additionally activating the PPAR-dependent pathway already shown to provide relief in animal models of MS after activation of GPR109a/HM74a. Thus nicotinic acid is uniquely suited for providing therapeutic relief in MS. However nicotinic acid is unexamined in MS research. Nicotinic acid penetrates the blood brain barrier, cures pellagric dementia, has been used for over 50 years clinically without toxicity, and raises HDL concentrations to a greater degree than any pharmaceutical, thus providing unparalleled benefits against lipodystrophy. Summary analysis reveals that the expected therapeutic benefits of high-dose nicotinic

    To determine whether there are gender-based differences in the clinical presentation, therapeutic approaches and outcomes in acute poisoning treated with activated charcoal. A descriptive study conducted in the Emergency Department of the Hospital Clínic de Barcelona over the 7 years between the years 2001 and 2008. The study included poisoned patients who had received activated charcoal. The variables included, epidemiological data, clinical and toxicological presentation, therapeutic approach, time in emergency department and outcomes. A total of 575 patients were included in the study. The mean age was 37.8 (SD 14.8) years and 65.7% were females. No differences were observed between males and females with respect to age, number of drugs involved in the poisoning or the number of tablets ingested, but a higher prevalence of benzodiazepine poisoning was observed in females compared to males (69.8 vs. 61.2%; Pactivated charcoal in non-drug poisoning was also more common in males than in females (7.9 vs. 3.2%; P<0.05). There were no differences between genders as regards clinical presentation of the poisonings, delays in care, hours of emergency department stay, treatment or outcome. Benzodiazepine poisoning was more prevalent in females than in males. Non-drug poisonings and alcohol combined with drug ingestion were more common in males. The clinical outcomes of the poisonings, delays in care, therapeutic requirements and admissions were similar between genders. Copyright © 2010 Elsevier España, S.L. All rights reserved.

    Therapeutic Touch (TT) is a widely used complementary therapy. This study investigated the effects of TT on hemoglobin and hematocrit level in students who were basically healthy. The volunteers with a hemoglobin level less than 12 grams per deciliter (g/dl) were randomly assigned to three groups of TT, mimic therapeutic touch (MT), and control. Blood samples were collected before the first treatment and again a week after the last one and measurements were taken. TT increased the level of hemoglobin (.99 .13 g/dl) and hematocrit (2.82 .43%) significantly. MT also increased the level of hemoglobin (.55 .11 g/dl) and hematocrit (2.75 .44%) significantly. No significant changes were found in the control group. TT increased hemoglobin more effectively than MT (p< .05). Significant changes of both variables in TT and MTgroups suggest that more careful precision might be needed while selecting individuals as sham therapists in further experiments.

    Monoclonal antibody (mAb) drugs have been widely used for treating tumor necrosis factor α (TNFα)-related diseases for over 10 years. Although their action has been hypothesized to depend in part on their ability to bind precursor cell surface TNFα, the precise mechanism and the epitope bound on TNFα remain unclear. In the present work, we report the crystal structure of the infliximab Fab fragment in complex with TNFα at a resolution of 2.6 Å. The key features of the TNFα E-F loop region in this complex distinguish the interaction between infliximab and TNFα from other TNF-receptor structures, revealing the mechanism of TNFα inhibition by overlapping with the TNFα-receptor interface and indicating the crucial role of the E-F loop in the action of this therapeutic antibody. This structure also indicates the formation of an aggregated network for the activation of complement-dependent cytolysis and antibody-dependent cell-mediated cytotoxicity, which result in development of granulomatous infections through TNFα blockage. These results provide the first experimental model for the interaction of TNFα with therapeutic antibodies and offer useful information for antibody optimization by understanding the precise molecular mechanism of TNFα inhibition.

    Yu-Tang Tung

    2013-01-01

    Full Text Available Andrographolide is one of the major diterpene lactones found in Andrographis paniculata Nees and exhibits remarkable inhibitory effects on various cancers. In this study, the antipulmonary cancer effects of andrographolide were studied in a lung tumor mouse model induced by human vascular endothelial growth factor A165 (hVEGF-A165. These results demonstrated that andrographolide significantly reduced the expression of hVEGF-A165 compared with a mock group in the Clara cells of the lungs. In addition, andrographolide also decreased tumor formation by reducing VEGF, EGFR, Cyclin A, and Cyclin B expression on the transcriptional and translational levels. These results indicated that andrographolide treatment on the overexpression of VEGF can arrest the cell cycle, which induced pulmonary tumors in transgenic mice. In conclusion, the antiangiogenesis and chemotherapeutic potential of andrographolide may provide a cure for pulmonary tumors in the future.

    Naegleria fowleri is a ubiquitous, pathogenic free-living amoeba; it is the most virulent Naegleria species and causes primary amoebic meningoencephalitis (PAME) in laboratory animals and humans. Although amphotericin B is currently the only agent available for the treatment of PAME, it is a very toxic antibiotic and may cause many adverse effects on other organs. In order to find other potentially therapeutic agents for N. fowleri infection, the present study was undertaken to evaluate the in vitro and in vivo efficacies of miltefosine and chlorpromazine against pathogenic N. fowleri. The result showed that the growth of the amoeba was effectively inhibited by treatment with amphotericin B, miltefosine, and chlorpromazine. When N. fowleri trophozoites were treated with amphotericin B, miltefosine, and chlorpromazine, the MICs of the drug were 0.78, 25, and 12.5 microg/ml, respectively, on day 2. In experimental meningoencephalitis of mice that is caused by N. fowleri, the survival rates of mice treated with amphotericin B, miltefosine, and chlorpromazine were 40, 55, and 75%, respectively, during 1 month. The average mean time to death for the amphotericin B, miltefosine, and chlorpromazine treatments was 17.9 days. In this study, the effect of drugs was found to be optimal when 20 mg/kg was administered three times on days 3, 7, and 11. Finally, chlorpromazine had the best therapeutic activity against N. fowleri in vitro and in vivo. Therefore, it may be a more useful therapeutic agent for the treatment of PAME than amphotericin B.

    This study was designed to confirm the effect of therapeutic intraoperative auditory suggestion on recovery from anesthesia, to establish the effect of preoperative suggestion, and to assess implicit memory for intraoperative information using an indirect memory task. Sixty consenting unpremedicated patients scheduled for elective gynecologic surgery were randomly divided into three equal groups: Group 1 received a tape of therapeutic suggestions preoperatively, and the story of Robinson Crusoe intraoperatively; Group 2 heard the story of Peter Pan preoperatively and therapeutic suggestions intraoperatively; Group 3 heard the Crusoe story preoperatively and the Peter Pan story intraoperatively. A standardized anesthetic technique was used with fentanyl, propofol, isoflurane, and nitrous oxide. After surgery, all patients received patient-controlled analgesia (PCA) with a standardized regimen. In the 24 h postsurgery, morphine use was recorded every 6 h and at 24 h an indirect memory test (free association) was used to test for memory of the stories. Anxiety scores were measured before surgery and at 6 and 24 h postsurgery. There were no significant differences between groups for postoperative morphine use, pain or nausea scores, anxiety scores, or days spent in hospital after surgery. Seven of 20 patients who heard the Pan story intraoperative gave a positive association with the word "Hook," whereas 2 of 20 who did not hear the story gave such an association. Indirect memory for the Pan story was established using confidence interval (CI) analysis. (The 95% CI for difference in proportion did not include zero). No indirect memory for the Crusoe story could be demonstrated. This study did not confirm previous work which suggested that positive therapeutic auditory suggestions, played intraoperatively, reduced PCA morphine requirements. In contrast, a positive implicit memory effect was found for a story presented intraoperatively.

    Objective: To study the therapeutic effect and find new ways on treatment of Grave's hyperthyroidism in youngsters. Methods: 260 Grave's hyperthyroidism patients (age under 21 years) treated with 131 I were followed up 1-16 years later. Results: 118 of all patients were cured and 55 cases improved, failed treatment 2 cases, subclinical hypothyroidism 9 cases, clinical hypothyroidism 6 cases. 35 cases were treated with 131 I two or three times. All the patients with subclinical hypothyroidism and clinical hypothyroidism caused by 131 I were cured with medicine. 131 I treatment had no effect on growth and mentality and didn't cause leukemia nor thyroid cancer. Conclusions: The therapy of youngsters with Grave's hyperthyroidism with 131 I has the same effectiveness as adult. To the youngster Grave's patients who failed medical treatment, therapy with 131 I is safe and effective. It leads to temporary hypothyroidism which can be cured with medicine, no delayed hypothyroidism has been found

    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 a phase I-II trial, 38 patients with acute myeloid leukemia (AML) were given single drug induction therapy with aclarubicin (ACM) according to two dosing schedules: treatment 1: 10 to 30 mg/m2/d to a maximum total dose of 300 mg/m2 or until development of unacceptable toxicity: treatment 2: 15 mg/m2/d in ten-day courses separated by ten-day intervals. Response rates were 15% with treatment 1 and 44% with treatment 2 (overall response rate 34%). Complete remission (CR) was achieved in 6 patients who had previously failed to respond to adriamycin (ADM). Toxicity was more frequent and more severe in those patients given more than 150 mg/m2 ACM per course. The main side effects were oropharyngeal mucositis and diarrhea. Three patients exhibited T wave inversion and one had an episode of auricular flutter. In a separate trial in 16 patients with AML we used cyclic chemotherapy combining ACM (20 mg/m2/d) and ARA-C (200 mg/m2/d) for seven consecutive days. Complete remission rate was 50%. Severe ventricular rhythm disorders were seen in two patients. In a phase I-II study, 19 patients with acute lymphoid leukemia (ALL) and 8 patients with non-Hodgkin lymphoma (NHL) were given ACM alone according to the regimen designated treatment 1 described above. Response rates were 11% (2/19) in ALL and 25% (2/8) in NHL. A review of the literature is presented in the discussion of the original trials reported herein.

    Full Text Available The high prevalence of major depressive disorder in people with Parkinson's disease, its negative impact on health-related quality of life and the low response rate to conventional pharmacological therapies call to seek innovative treatments. Here, we review the new approaches for treating major depressive disorder in patients with Parkinson's disease within the framework of the network model of depression. According to this model, major depressive disorder reflects maladaptive neuronal plasticity. Non-invasive brain stimulation using high frequency repetitive transcranial magnetic stimulation over the prefrontal cortex has been proposed as a feasible and effective strategy with minimal risk. The neurobiological basis of its therapeutic effect may involve neuroplastic modifications in limbic and cognitive networks. However, the way this networks reorganize might be strongly influenced by the environment. To address this issue, we propose a combined strategy that includes non-invasive brain stimulation together with cognitive and behavioral interventions.

    The high prevalence of major depressive disorder in people with Parkinson’s disease (PD), its negative impact on health-related quality of life and the low response rate to conventional pharmacological therapies call to seek innovative treatments. Here, we review the new approaches for treating major depressive disorder in patients with PD within the framework of the network model of depression. According to this model, major depressive disorder reflects maladaptive neuronal plasticity. Non-invasive brain stimulation (NIBS) using high frequency repetitive transcranial magnetic stimulation (rTMS) over the prefrontal cortex has been proposed as a feasible and effective strategy with minimal risk. The neurobiological basis of its therapeutic effect may involve neuroplastic modifications in limbic and cognitive networks. However, the way this networks reorganize might be strongly influenced by the environment.

    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.

    Stem cells have the capability of self-renewal and can differentiate into different cell types that might be used in regenerative medicine. Neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), and amyotrophic lateral sclerosis (ALS) currently lack effective treatments. Although stem cell therapy is still on the way from bench to bedside, we consider that it might provide new hope for patients suffering with neurodegenerative diseases. In this article, we will give an overview of recent studies on the potential therapeutic use of mesenchymal stem cells (MSCs), neural stem cells (NSCs), embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), and perinatal stem cells to neurodegenerative disorders and we will describe their immunomodulatory mechanisms of action in specific therapeutic modalities.

    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.

    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

    To assess the therapeutic efficacy of local injections of botulinum toxin type A (Btx-A) in improving blood flow to the hands of patients with Raynaud's phenomenon (RP) secondary to scleroderma. In this randomized, double-blind, placebo-controlled clinical trial, patients with scleroderma-associated RP received Btx-A (50 units in 2.5 ml sterile saline) in one randomly selected hand and sterile saline (2.5 ml) in the opposite hand. Follow-up at 1 and 4 months postinjection included laser Doppler imaging of hands, patient-reported outcomes, and physical examination. We compared outcomes using paired t-tests and population-average generalized models with generalized estimating equations. Of 40 patients enrolled, 25 had limited scleroderma and 15 had diffuse scleroderma. From baseline to 1-month follow-up, there was a greater reduction in average blood flow in Btx-A-treated hands compared to placebo-treated hands. The model estimated that this difference was statistically significant (average difference -30.08 flux units [95% confidence interval -56.19, -3.98], P for interaction = 0.024). This difference was mainly influenced by patients with longstanding RP and diffuse scleroderma. Change in blood flow at 4-month follow-up was not significantly different between groups. Clinical measures (QuickDASH, McCabe Cold Sensitivity Score, pain on a visual analog scale, and Raynaud's Condition Score) improved slightly for Btx-A-treated hands. Our laboratory-based laser Doppler imaging flow data do not support using Btx-A to treat RP in all scleroderma patients. The secondary clinical outcomes suggest some positive effect, but its clinical meaningfulness is questionable. The role of Btx-A in treating RP should be further studied with more homogeneous patient populations and in unique clinical situations such as acute digital ischemia. © 2017, American College of Rheumatology.

    This review summarizes the most important facts regarding the clinical effectiveness of oral photochemotherapy for psoriasis with UV radiation at 320-400 nm (UVA) and selected furocoumarins. The most widely used compound is 8-methoxypsoralen (8-MOP); its effectiveness has been documented by many clinical trials. Oral 5-methoxypsoralen (5-MOP) has been evaluated as an alternative drug because it is less erythemogenic and thus reduces the danger of accidental over-exposure. It has been as effective as 8-MOP in clearing psoriasis, but the UVA doses required were considerably higher. Although oral 4,5',8-trimethylpsoralen does not clear psoriasis satisfactorily, excellent treatment results have been recorded when it was applied topically. The 3 drugs produce bifunctional adducts with DNA (cross-links), which may be of particular importance for mutagenesis and tumor formation. In an attempt to reduce possible oncogenic hazards, investigators are currently testing non-crosslinking furocoumarins for their therapeutic effectiveness. At present, these compounds are available for topical use only. 3-Carbethoxypsoralen has been reported to produce excellent treatment results by others but was ineffective in our clinical trials. Similarly disappointing was the application of 4,5'-dimethylangelicin and 5-methylangelicin. Although monofunctional compounds also inhibit cell proliferation in vitro, it appears that cross-linking is a prerequisite for the therapeutic success in psoriasis. The actual important of cross-links, however, remains to be clarified.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Abstract Background Stem cell-based therapy to treat liver diseases is a focus of current research worldwide. So far, most such studies depend on rodent hepatic failure models. The purpose of this study was to isolate mesenchymal stem cells from human placenta (hPMSCs and determine their therapeutic potential for treating Chinese experimental miniature pigs with acute liver failure (ALF. Methods hPMSCs were isolated and analyzed for their purity and differentiation potential before being employed as the donor cells for transplantation. ALF models of Chinese experimental miniature pigs were established and divided into four groups: no cell transplantation; hPMSCs transplantation via the jugular vein; X-ray-treated hPMSCs transplantation via the portal vein; and hPMSCs transplantation via the portal vein. The restoration of biological functions of the livers receiving transplantation was assessed via a variety of approaches such as mortality rate determination, serum biochemical analysis, and histological, immunohistochemical, and genetic analysis. Results hPMSCs expressed high levels of CD29, CD73, CD13, and CD90, had adipogenic, osteogenic, and hepatic differentiation potential. They improved liver functions in vivo after transplantation into the D-galactosamine-injured pig livers as evidenced by the fact that ALT, AST, ALP, CHE, TBIL, and TBA concentrations returned to normal levels in recipient ALF pigs. Meanwhile, histological data revealed that transplantation of hPMSCs via the portal vein reduced liver inflammation, decreased hepatic denaturation and necrosis, and promoted liver regeneration. These ameliorations were not found in the other three groups. The result of 7-day survival rates suggested that hPMSCs transplantation via the portal vein was able to significantly prolong the survival of ALF pigs compared with the other three groups. Histochemistry and RT-PCR results confirmed the presence of transplanted human cells in recipient pig

    Cancer cell metabolism described by Otto Warburg in the thirties became a cancer specific hallmark, also called "Warburg effect". Cancer cells use essentially glucose as fuel, through glycolysis, in order to meet their energy and biomass needs to insure their cell proliferation. Recent advances describe Warburg effect regulation by oncogenes and tumor suppressor genes. Moreover, mutations in some glycolysis enzymes are found in various cancers, highlighting the role of cell metabolism in cancer. In this review, we describe the mechanisms responsible for the Warburg effect at the molecular and cellular level, the role of cell signalling along with the implication of different transcription factors. As a cause or a consequence of tumorigenesis, the Warburg effect is now considered as a promising therapeutic target in the fight against cancer. © 2013 médecine/sciences – Inserm.

    Results: Metoprolol, an antagonist, significantly decreased the thermal latency and mechanical thresholds with dose and time dependent manner. However, dobutamine, an agonist, enhanced the latency and thresholds dose and time dependent. Conclusions: This results suggest that in contrast to dobutamine, locally treated metoprolol may cause hyperalgesic and allodynic actions. In addition, our results can demonstrate that peripheral beta-adrenergic receptors can play important roles in nociceptive process. [Cukurova Med J 2015; 40(2.000: 258-266

    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.

    To probe into the application of fuzzy cluster in analysis of therapeutic effects of electro-acupuncture at different parameters on adjuvant-induced arthritis (AA) in rats. One hundred Wistar rats were randomly divided into ten groups: normal control group, untreated group and eight electro-acupuncture groups at different parameters. There were ten rats in each group. AA rats were treated by electro-acupuncture at different frequencies (2 Hz or 100 Hz), waveforms (successive wave or intermittent wave) and current intensities (0.1 mA or 0.2 mA). Firstly, the anti-inflammatory and analgesic effects of electro-acupuncture at different parameters were compared with orthogonal experiment, and then with the application of fuzzy mathematics, the data of joint swelling, pain threshold and the contents of beta-endorphin (beta-EP) and interleukin-1beta (IL-1beta) after the treatment in all groups were standardized by the method of data range normalization. Programming and solution were done by MATLAB. The methods of fuzzy similar matrix and the transitive closure were used in similarity evaluation of therapeutic effects of electro-acupuncture at different parameters. Based on index determination and variance analysis, both the normal control group and untreated group were clustered to one category as lambda equaled to 0.72. Electro-acupuncture at 100 Hz, successive wave, 0.2 mA, electro-acupuncture at 100 Hz, intermittent wave, 0.1 mA and electro-acupuncture at 100 Hz, intermittent wave, 0.2 mA were clustered to one category and had similar good anti-inflammatory and analgesic effects. The therapeutic effects of the remaining electro-acupuncture types were similar. Fuzzy cluster analysis provides a better method for evaluating the overall therapeutic effects of electro-acupuncture with multiple factors.

  20. New insights into cannabis consumption; abuses and possible therapeutic effects

    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.

    This study aimed to investigate the therapeutic mechanism of treating SMMC-7721 liver cancer cells with magnetic fluid hyperthermia (MFH) using Fe{sub 2}O{sub 3} nanoparticles. Hepatocarcinoma SMMC-7721 cells cultured in vitro were treated with ferrofluid containing Fe{sub 2}O{sub 3} nanoparticles and irradiated with an alternating radio frequency magnetic field. The influence of the treatment on the cells was examined by inverted microscopy, MTT and flow cytometry. To study the therapeutic mechanism of the Fe{sub 2}O{sub 3} MFH, Hsp70, Bax, Bcl-2 and p53 were detected by immunocytochemistry and reverse transcription polymerase chain reaction (RT-PCR). It was shown that Fe{sub 2}O{sub 3} MFH could cause cellular necrosis, induce cellular apoptosis, and significantly inhibit cellular growth, all of which appeared to be dependent on the concentration of the Fe{sub 2}O{sub 3} nanoparticles. Immunocytochemistry results showed that MFH could induce high expression of Hsp70 and Bax, decrease the expression of mutant p53, and had little effect on Bcl-2. RT-PCR indicated that Hsp70 expression was high in the early stage of MFH (,24 h) and became low or absent after 24 h of MFH treatment. It can be concluded that Fe{sub 2}O{sub 3} MFH significantly inhibited the proliferation of in vitro cultured liver cancer cells (SMMC-7721), induced cell apoptosis and arrested the cell cycle at the G2/M phase. Fe{sub 2}O{sub 3} MFH can induce high Hsp70 expression at an early stage, enhance the expression of Bax, and decrease the expression of mutant p53, which promotes the apoptosis of tumor cells.

    Oxiracetam, a new substance found to be a nootropic in experimental pharmacological studies, was tested in three clinical trials: a single rising dose tolerance and dose-finding study with quantitative pharmaco-electroencephalogram (pharmaco-EEG) and quantitative pharmacopsychology in healthy volunteers; a dose-finding study, at three dose levels for 3 months, with quantitative pharmaco-EEG in mild to moderate dementia patients; and a safety and efficacy study with increasing dosages for 12 weeks with subjective and objective tests in elderly patients with dementia. In single and repeated oral dosages up to 2,400 mg, oxiracetam is a safe compound. According to HZI Data Bank Classification Systems, oxiracetam is a vigilance-enhancing compound with some effects on spontaneous memory. The therapeutic effect of oxiracetam can be discriminated from placebo, and in comparison with piracetam, oxiracetam exhibits greater improvement in memory factor.

    The purpose of this study was to investigate the potential therapeutic qualities of Δ9-tetrahydrocannabinol (THC) with respect to slowing or halting the hallmark characteristics of Alzheimer's disease. N2a-variant amyloid-β protein precursor (AβPP) cells were incubated with THC and assayed for amyloid-β (Aβ) levels at the 6-, 24-, and 48-hour time marks. THC was also tested for synergy with caffeine, in respect to the reduction of the Aβ level in N2a/AβPPswe cells. THC was also tested to determine if multiple treatments were beneficial. The MTT assay was performed to test the toxicity of THC. Thioflavin T assays and western blots were performed to test the direct anti-Aβ aggregation significance of THC. Lastly, THC was tested to determine its effects on glycogen synthase kinase-3β (GSK-3β) and related signaling pathways. From the results, we have discovered THC to be effective at lowering Aβ levels in N2a/AβPPswe cells at extremely low concentrations in a dose-dependent manner. However, no additive effect was found by combining caffeine and THC together. We did discover that THC directly interacts with Aβ peptide, thereby inhibiting aggregation. Furthermore, THC was effective at lowering both total GSK-3β levels and phosphorylated GSK-3β in a dose-dependent manner at low concentrations. At the treatment concentrations, no toxicity was observed and the CB1 receptor was not significantly upregulated. Additionally, low doses of THC can enhance mitochondria function and does not inhibit melatonin's enhancement of mitochondria function. These sets of data strongly suggest that THC could be a potential therapeutic treatment option for Alzheimer's disease through multiple functions and pathways.

    Full Text Available 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 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 sigma-1 receptor which can explain its widespread therapeutic indications.

    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.

    Full Text Available The therapeutic effect of polysaccharide of large yellow croaker swim bladder (PLYCSB on lupus nephritis has been studied in vivo. A high concentration (50 mg/kg dose of PLYCSB reduced the levels of serum inflammatory cytokine levels of IL-6, IL-12, TNF-α and IFN-γ compared to a low concentration (25 mg/kg dose and control mice. SCr, BUN, TC and TG serum levels of PLYCSB treated mice were lower than those of control mice, and TP and ALB serum levels were higher than control mice. Control mice tested ds-DNA positive at the 6th week, and 50 mg/kg treated mice tested at the 10th week after the experiment began. The output of urine protein of 50 mg/kg PLYCSB treated mice was most closely comparable to the normal mice. The glomerular number of 50 mg/kg PLYCSB treated mice was more than the 25 mg/kg dose and control groups, and the 50 mg/kg dose group showed the lowest glomerular sclerosis index in lupus nephritis mice. By RT-PCR and western blot assay, PLYCSB significantly induced inflammation in kidney tissues of mice by downregulating NF-κB-p65, TGF-β1, Fas, FasL and upregulating IκB-α. These results suggest that PLYCSB showed a potential curative effect on lupus nephritis as a drug or functional food.

    Full Text Available Danshen is a traditional Chinese medicine with many beneficial effects on cardiovascular diseases. The aim of this study was to evaluate the mechanisms responsible for the antiatherogenic effect of water soluble Danshen extracts (DEs. Rat vascular smooth muscle cells (VSMCs and human umbilical vein endothelial cells (HUVECs were treated with DE. To evaluate the effects of DE in vivo, carotid balloon injury and tail vein thrombosis were induced in Sprague-Dawley (SD rats and iliac artery stent was induced in New Zealand white rabbits. The inhibitory action of DE on platelet aggregation was confirmed with an impedance aggregometer. DE inhibited the production of reactive oxygen species, and the migration and proliferation of platelet-derived growth factor-BB stimulated VSMCs. Furthermore, DE prevented inflammation and apoptosis in HUVECs. Both effects of DE were reconfirmed in both rat models. DE treatment attenuated platelet aggregation in both in vivo and ex vivo conditions. Pretreatment with DE prevented tail vein thrombosis, which is normally induced by κ-carrageenan injection. Lastly, DE-treated rabbits showed decreased in-stent restenosis of stented iliac arteries. These results suggest that water soluble DE modulates key atherogenic events in VSMCs, endothelial cells, and platelets in both in vitro and in vivo conditions.

    Sepsis is a life-threatening complication of an infection and remains one of the leading causes of mortality in surgical patients. Bacteremia induces excessive inflammatory responses that result in multiple organ damage. Chronic helminth infection and helminth-derived materials have been found to immunomodulate host immune system to reduce inflammation against some allergic or inflammatory diseases. Schistosoma japonicum cystatin (Sj-Cys) is a cysteine protease inhibitor that induces regulatory T-cells and a potential immunomodulatory. The effect of Sj-Cys on reducing sepsis inflammation and mortality was investigated. Sepsis was induced in BALB/c mice using cecal ligation and puncture (CLP), followed by intraperitoneal injection of different doses (10, 25 or 50 μg) of recombinant Sj-Cys (rSj-Cys). The therapeutic effect of rSj-Cys on sepsis was evaluated by observing the survival rates of mice for 96 h after CLP and the pathological injury of liver, kidney and lung by measuring the levels of alanine transaminase (ALT), aspartate transaminase (AST), blood urea nitrogen (BUN) and creatinine (Cr) in sera and the tissue sections pathology, and the expression of MyD88 in liver, kidney and lung tissues. The immunological mechanism was investigated by examining pro-inflammatory cytokines (TNF-α, IL-6, IL-1β) and IL-10 and TGF-β1 in mice sera and in culture of macrophages stimulated by lipopolysaccharides (LPS). rSj-Cys treatment provided significant therapeutic effects on CLP-induced sepsis in mice demonstrated with increased survival rates, alleviated overall disease severity and tissue injury of liver, kidney and lung. The rSj-Cys conferred therapeutic efficacy was associated with upregualted IL-10 and TGF-β1 cytokines and reduced pro-inflammatory cytokines TNF-α, IL-6, IL-1β. MyD88 expression in liver, kidney and lung tissues of rSj-Cys-treated mice was reduced. In vitro assay with macrophages also showed that rSj-Cys inhibited the release of pro

    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.

    The placebo effect is an excellent model for understanding the mechanisms underlying the interaction between a subjective and complex mental activity (beliefs, expectations, hopes, learning, patient-physician relationship, socio-cultural context .) with different neural and biological systems. Initially, research on the placebo effect has focused on the mechanisms of pain and analgesia. The cognitive processes of conditioning and reward anticipation (hope of a relief) were highlighted. The involvement of different neurobiological pathways has been clearly shown: endogenous opioids, CCK, dopaminergic pathways, endocannabinoids, immunological factors... More recently, the field has open towards new perspectives: depression and anxiety, motor disorders, immune system, endocrine system. Intensive research in the field emerges because of its fundamental implications in neuroscience research but also because of the ethical, clinical and therapeutical issues. Moreover, the placebo effect is considered as a main methodological mean issue in clinical trials that allows the demonstration of the efficacy and tolerance of new drugs. In the field of psychiatry, depression is a placebo highly-sensitive disorder: placebo response rates in clinical trials are of the order of 30 % to 40 %. The identification of biological markers of placebo response, such as neuroimaging and quantitative electroencephalography may lead to develop more efficient models in clinical research.

    2007-01-01

    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.

    Despite multiple publications on potential therapies for neuromuscular diseases (NMD) in cell and animal models only a handful reach clinical trials. The ability to prioritise drug development according to objective criteria is particularly critical in rare diseases with large unmet needs and a limited numbers of patients who can be enrolled into clinical trials. TREAT-NMD Advisory Committee for Therapeutics (TACT) was established to provide independent and objective guidance on the preclinical and development pathway of potential therapies (whether novel or repurposed) for NMD.We present our experience in the establishment and operation of the TACT. TACT provides a unique resource of recognized experts from multiple disciplines. The goal of each TACT review is to help the sponsor to position the candidate compound along a realistic and well-informed plan to clinical trials, and eventual registration. The reviews and subsequent recommendations are focused on generating meaningful and rigorous data that can enable clear go/no-go decisions and facilitate longer term funding or partnering opportunities. The review process thereby acts to comment on viability, de-risking the process of proceeding on a development programme.To date TACT has held 10 review meeting and reviewed 29 program applications in several rare neuromuscular diseases: Of the 29 programs reviewed, 19 were from industry and 10 were from academia; 15 were for novel compounds and 14 were for repurposed drugs; 16 were small molecules and 13 were biologics; 14 were preclinical stage applications and 15 were clinical stage applications. 3 had received Orphan drug designation from European Medicines Agency and 3 from Food and Drug Administration. A number of recurrent themes emerged over the course of the reviews and we found that applicants frequently require advice and education on issues concerned with preclinical standard operating procedures, interactions with regulatory agencies, formulation

    Full Text Available The role of nitric oxide and its reactive derivatives (NOx is well known in the pathogenesis of multiple sclerosis, which is an inflammatory disease while NOx seems to be important in coordinating inflammatory response. The purpose of the present study was to assess serum NOx as one of the nitrogen species and inflammatory parameters in relapsing-remitting multiple sclerosis patients and to compare the effectiveness of various types of disease-modifying therapies that reduce nitric oxide and inflammatory biomarkers. Elevated NOx level was observed in patients who received the first-line disease-modifying therapy (interferons beta-1a and beta-1b in comparison with the subjects treated with the second-line disease-modifying therapy (natalizumab; fingolimod and healthy controls without significant differences in C-reactive protein and interleukin-1 beta. A negative correlation was observed between serum NOx level and the duration of multiple sclerosis confirmed in the whole study population and in subjects treated with the first-line agents. Only serum NOx, concentration could reveal a potential efficacy of disease-modifying therapy with a better reduction in NOx level due to the second-line agents of disease-modifying therapy.

    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.

    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

    Since 1942, therapy with radioiodine (Na 131 I) has gained a major role in the treatment of benign thyroid disorders, notably hyperthyroidism caused by Graves' disease or toxic multi nodular goiter. The very large series of patients treated so far offer the opportunity for an assessment of both benign and malignant side effects. Hyperthyroidism is sometimes observed after radioiodine therapy due to radiation induced thyroid hormone or by an immunological mechanism. Despite the numerous attempts to design dosage schedules aiming at euthyroidism, hypothyroidism occurs in the majority of patients throughout life. Transient hypothyroidism may be observed within the first year after therapy and is caused by an immunological mechanism. Radioiodine therapy in Graves' disease may induce or worsen ophthalmopathy, which can be prevented by steroids effectively. Hypoparathyroidism and hyperparathyroidism have been reported after radioiodine therapy but probably do not exceed the normal incidence. Sialitis is commonly observed but mostly in patients treated with radioiodine for thyroid cancer. There are no indications for induction of genetic abnormalities after radioiodine therapy although no definite conclusion can be reached. Much attention has been paid to malignant disease. In very large series, no effects of radioiodine therapy on survival have been observed. Some studies report an increased relative risk for certain types of cancer (notably thyroid cancer, stomach cancer, bladder and kidney cancer or hematological malignancies). However, these observations were not confirmed by other large studies, so that no definite conclusion with respect to risk for certain types of malignant disease can be drawn. However, radioiodine therapy for benign thyroid disorders has generally considered safe and without major side effects, hypothyroidism being the most frequent one

    Experimental autoimmune encephalomyelitis (EAE) is a prototypic Th1-mediated autoimmune inflammatory disease of the central nervous system (CNS), and serves as a model for the human demyelinating disease, multiple sclerosis. Cisplatin is a drug widely used in the treatment of a variety of human neoplasias, such as advanced bladder carcinoma, adrenal cortex carcinoma, breast cancer, head and neck or lung carcinoma. Cisplatin binds to DNA and interferes with cellular repair and other mechanism, which eventually result into cell death. It is known that cisplatin can induce immunosuppressive effects through inhibition of T cell activity. Therefore we analyzed the anti-inflammatory effects of cisplatin in a rat EAE model. EAE was induced in male LEW rats by immunizing with a synthetic peptide of guinea pig myelin basic protein. The development of EAE and neurological signs were evaluated by a standard protocol. Immunohistochemistry was applied to show immune cell infiltration into the CNS. Early treatment of EAE rats with cisplatin effectively ameliorated the development of disease and provided a significant protective effect compared to control rats. Further, histological analysis demonstrated that the formation of the typical perivascular cuffs and brain infiltration of monocytes and lymphocytes were complete absent in cisplatin treated rats, while abundant T cell infiltration was seen in the CNS of EAE rats. Our data show that cisplatin has protective effects in EAE, indicating that cisplatin could be a candidate in the treatment of human CNS autoimmunity.

    As human beings live longer, age-related diseases such as osteoporosis will become more prevalent. Intolerant side effects and poor responses to current treatments are observed. Therefore, novel effective therapeutic agents are greatly needed. Here, pyrazole derivatives were designed and synthesized, and their osteoclastogenesis inhibitory effects both in vitro and in vivo were evaluated. The most promising compound 13 with a 2-(dimethylamino)ethyl group inhibited markedly in vitro osteoclastogenesis as well as the bone resorption activity of osteoclasts. Compound 13 affected osteoclast's early proliferation and differentiation more than later fusion and maturation stages. In ovariectomized (OVX) mice, compound 13 can inhibit the loss of trabecular bone volume, trabecular bone number, and trabecular thickness. Moreover, compound 13 can antagonize OVX-induced reduction of serum bone resorption marker and then compensatory increase of the bone formation marker. To sum up, compound 13 has high potential to be developed into a novel therapeutic agent for treating osteoporosis in the future.

    Full Text Available Diabetes is a global pandemic which warrants urgent attention due to its rising prevalence and economic burden. Thus, many alternative therapies are being researched for antidiabetic properties, given the inefficacy of current medicinal treatments. From this perspective, Aronia melanocarpa or black chokeberry has been investigated for its therapeutic properties in many studies, especially for its ability to combat hyperglycemia-induced oxidative stress and the macrovascular complications of diabetes including cardiovascular disease. Though A. melanocarpa is native to the eastern areas of North America, it has been planted extensively in Europe and Asia as well. Several in vivo studies have displayed the antioxidant properties of A. melanocarpa berry juice and plant extract in rat models where oxidative stress markers were observed to have significant reductions. Some of the potent bioactive compounds present in the fruits and other parts of the plant were identified as (−-epicatechin, chlorogenic acid, neochlorogenic acid, and cyanidin-3-galactoside. Overall, A. melanocarpa could be considered a good source of antioxidants which is effective in combating hyperglycemia-induced oxidative stress.

    Therapeutic Touch (TT) is a complementary modality that has been demonstrated to reduce psychological distress and help patients to relax. It is unclear if there is an impact of TT on biobehavioral markers such as cortisol and natural killer cells (NKCs). There is some preliminary evidence that suggests relaxation may have positive effects on the immune system. To test the efficacy of TT on pain and biobehavioral markers in patients recovering from vascular surgery. The study was grounded in a psychoneuroimmunology framework to address how complementary therapies affect pain and biobehavioral markers associated with recovery in surgical patients. This was a between-subjects intervention study. Twenty-one postoperative surgical patients. Measures of level of pain and levels of cortisol and NKCs were obtained before and after a TT treatment. Compared with those who received usual care, participants who received TT had significantly lower level of pain, lower cortisol level, and higher NKC level. Evidence supports TT as a beneficial intervention with patients. Future research on TT is still needed to learn more about how it functions. However, there is evidence to support incorporating TT into nursing practice.

    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.

    Chronic exposure to catalytically treated or noncatalytically treated automobile exhaust significantly depressed the spontaneous locomotor activity (SLA) of rats. Exposure to H/sub 2/SO/sub 4/ alone or CO at comparable levels did not alter the SLA. Exposure to noncatalytically treated exhaust resulted in significant reductions in growth rate and food and water intake. However, these effects were not evident in the exposure to catalytically treated exhaust or in the control H/sub 2/SO/sub 4/ and CO exposures. Blood acid-base analyses indicated that exposure to either catalytically treated exhaust or H/sub 2/SO/sub 4/ elicits a metabolic alkalosis, while exposure to CO alone results in a metabolic acidosis. All acid-base parameters were within the normal range several weeks after the termination of exposure.

    Ulcerative colitis (UC) is a chronic and nonspecific intestinal inflammatory disease, which may increase the risk of colon cancer. Andrographolide is a main active component of Andrographis paniculata . The anti-inflammatory ability of andrographolide suggested its potential therapeutic effect against UC. In the present study, elevated serum concentrations of proinflammatory factors, including (TNF)-α, interleukin (IL)-1β, IL-6 and IL-23, as well as increased percentages of Th17 cells (IL-17+CD4+ cells) in CD4+ cells were detected in UC patients compared to that in healthy donors. These data suggested that Th17 immune responses may involve in the pathogenesis of UC. Experimental colitis mouse model was then established. The results of hematoxylin and eosin staining demonstrated the therapeutic effect of andrographolide on colitis. Enzyme-linked immunosorbent assay (ELISA), flow cytometry and western blotting analyses showed that andrographolide could decreased the levels of proinflammatory factors TNF-α, IL-1β, IL-6 and IL-17A in the serum and in the colon tissues, reduced the percentages of Th17 cells in CD4+ cells, and suppressed the levels of IL-23, IL-17A, ROR-γt (key transcription factor of Th17 cells) and p-STAT3 in the colon tissues. Further, peripheral blood mononuclear cells (PBMCs) were isolated from UC patients and treated with various concentrations of andrographolide (0, 10, 20 and 30 μg/ml). Andrographolide also showed inhibitory effects on the levels of proinflammatory factors, the percentages of Th17 cells and the expression of relative proteins. Similar results were obtained in lipopolysaccharide-treated normal PBMCs. These data suggested that andrographolide may inhibit Th17 immune response via STAT3 signaling. In conclusion, we demonstrated that andrographolide inhibited the activity of IL-23/IL-17 axis and down-stream pro-inflammatory factors so as to suppress inflammation response, resulting in the relieving of UC.

    Therapeutic effect of bone marrow transplantation (BMT) and blood transfusion on different groups of rats subjected to various doses of total body irradiation (TBI) was studied. In the control group, 80 rats that received TBI of 8,9,10,11 and 12 Gy died between 3∼14 days. In the second group, 67 rats that received the same doses of irradiation were treated with BMT. Except that 8 rats died from lung hemorrhages at 4∼6 days after TBI. 85% of these animals (500/59) showed hemopoietic engraftment. The survival rates of 8, 9, 10, 11 and 12 Gy subgroups at 90 days after BMT were 90%, 56%, 56%, 25% and 0% respectively. In the third group, 82 rats receive TBI and blood transfusion prior to BMT. Except that 8 rats subjected to 11∼12 Gy irradiation died from lung hemorrhage at 4∼6 days after BMT, 97% of these animals (72/74) showed hemopoietic engraftment. The 90-day survival rates of 8, 9, 10, 11 and 12 Gy subgroups were 93%, 80%, 80%, 60% and 6% respectively. The 90-day survival rate of 50 rats subjected to 9∼11 Gy TBI and treated with blood transfusion and BMT, was 72%, while that 47 rats treated simply with BMT was only 42%. These results showed clearly that previous blood transfusion could increase the rate of hemopoietic engraftment, reduce the incidence if rejection, and raise the survival rate

    Melasma is one of the most common cosmetic disorders with skin darkening. Although several treatment modalities are available, none is satisfactorily used in management of this condition. Tranexamic acid (TA), a plasmin inhibitor, is reported to improve melasma when injected locally or used as oral and topical forms. The aim of this study was to compare therapeutic effects of liposomal tranexamic acid and conventional hydroquinone on melasma. Thirty women with bilateral melasma were enrolled in a split-face trial lasting 12 weeks. Patients blindly applied 5% topical liposomal TA and 4% hydroquinone cream, to the designated sides of the face twice daily in addition to the assigned sunscreen in the morning. Skin pigmentation was measured using MASI (Melasma Area and Severity Index) at each visit separately for each side at the base line and every month until one month after treatment course. Data were obtained from patients file and were analyzed statistically using SPSS software, paired samples t-test, and repeated measured ANOVA. Twenty-three patients completed the study. The mean MASI scores significantly reduced in both treated sides (P < P = 0.001) after 12 week. A greater decrease was observed with 5% liposomal TA, although this difference was not statistically significant. Irritation occurred in three patients with hydroquinone, while no serious adverse events occurred with TA. On the basis of these results, topical liposomal TA can be used as a new, effective, safe, and promising therapeutic agent in melasma. © 2015 Wiley Periodicals, Inc.

    Probiotics, for the treatment of inflammatory bowel disease, are a group of specific nonpathogenic bacteria that are functionally and genetically defined by their ability to reduce inflammation in the intestine. Although probiotics also seem to have broad beneficial effects in humans, both as a food and as a therapeutic agent, there are specific identified mechanisms in some, but not all, of these bacteria that are important relative to the pathogenesis of inflammatory bowel disease. Recently, studies relative to the mechanism of action of probiotics have identified that these organisms can have a direct effect on epithelial cell function and intestinal health, including enhancing epithelial barrier function, modulating epithelial cytokine secretion into an anti-inflammatory dominant profile, altering mucus production, changing bacterial luminal flora, modifying the innate and systemic immune system, and inducing regulatory T-cell effects. For probiotics to have a therapeutic role in the management of clinical inflammatory bowel disease, their therapeutic mechanism of action must be aligned with the pathogenic mechanism of action of the disease. In this regard, the role of probiotics for the clinical treatment of inflammatory bowel disease is emerging as the mechanisms and pathogenesis are being unraveled. It remains clear that probiotics are able to reduce gastrointestinal inflammation by exerting positive effects on epithelial cell and mucosal immune dysfunction.

    New treatment modalities for vitiligo acting by changing certain cytokines and metalloproteinases are newly emerging. The aim of this work is to To assess the efficacy of trichloroacetic acid (TCA) chemical peel, dermapen, and fractional CO 2 laser in treatment of stable non-segmental vitiligo and to detect their effects on IL-17 and MMP-9 levels. Thirty patients with stable vitiligo were recruited in a randomized controlled study. They were randomly categorized into three equal groups. Group 1: TCA peel, Group 2: dermapen machine, and Group 3: Fractional CO 2 laser. Skin biopsies were taken from treated areas and from control areas for which MMP-9 and IL-17 tissue levels were measured using ELISA. The 30 vitiligo patients had low basal tissue MMP-9 levels and high baseline IL-17 tissue levels. As regards the three different used modalities, all of them caused rise in MMP-9 as well as IL-17 levels and almost their levels were much more elevated with repetition of the previously mentioned traumatic procedures. TCA 25% peel proved to be the most effective modality both clinically and laboratory and it can be used prior or with other conventional therapies in the treatment of vitiligo. © 2016 Wiley Periodicals, Inc.

  18. The Therapeutic Effect of Speechvive on Prosody in Parkinson's Disease

    Kiefer, Brianna Rose

    It is well known that physiological impairments secondary to Parkinson's Disease (PD) negatively impact speech production. Individuals with PD display vocal, prosodic, resonant, and articulatory abnormalities which reduce communicative effectiveness. Prosody is a broad term which refers to the alterations in pitch, duration, and loudness used by speakers to convey important linguistic and paralinguistic information during speech. Little is known about the prosodic abnormalities associated with PD relative to healthy older adults; however, it is well known that individuals with PD display impairments in their ability to modulate the acoustic cues (pitch, duration, intensity) associated with prosodic inflection in speech. Literature presently lacks sufficient evidence to support treatment paradigms commonly used to address dysprosody in PD. Thus, there is a significant need to develop and investigate potential evidence-based treatment paradigms for dysprosody associated with PD. The present study aimed to examine the potential treatment effects the SpeechVive device has on treating dysprosody in PD. Acoustic recordings were obtained from 15 individuals with PD during a reading task. Participants read the passage at the start of the study and 12 weeks later, after wearing the SpeechVive device for the intervening weeks. Main outcome measures examined productions of contrastive stress, intonation contours, rate, and patterns of pausing. The results revealed that participants increased vocal intensity levels during the production of stressed words and improved standard deviation of pitch during the productions of intonation contours. Lastly, the device was found to improve participants' abilities to pause relative to syntactic boundaries.

  19. Effect of radioimmunoassay procedures on therapeutic drug monitoring

    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

    Full Text Available Childhood inguinal herniorrhaphy is one common cause of seminal tract obstruction. Vasovasostomy (VV can reconstruct seminal deferens and result in appearance of sperm and natural pregnancy in some patients. Secondary epididymal obstruction caused by a relatively long-term vasal obstruction is a common cause of lower patency compared with VV due to vasectomy in adults. From July 2007 to June 2012, a total of 62 patients, with history of childhood inguinal herniorrhaphy and diagnosed as obstructive azoospermia were treated in our center. The overall patency rate and natural pregnancy rate were 56.5% (35/62 and 25.8% (16/62, respectively. 48.4% (30/62 of the patients underwent bilateral VV in the inguinal region, with a patency rate of 76.7% (23/30 and a natural pregnancy rate of 36.7% (11/30, respectively. 30.6% (19/62 of the patients underwent bilateral VV and unilateral or bilateral vasoepididymostomies due to ipsilateral epididymal obstruction with the patency and natural pregnancy rate decreasing to 63.2% (12/19 and 26.3% (5/19. 21.0% (13/62 of the patients merely underwent vasal exploration without reconstruction due to failure to find distal vasal stump, etc. Our study indicate that microsurgical reanastomosis is an effective treatment for some patients with seminal tract obstruction caused by childhood inguinal herniorrhaphy.

    Immunocompromised patients are at risk of developing toxoplasma encephalitis (TE). Standard therapy regimens (including sulfadiazine plus pyrimethamine) are hampered by severe side effects. While atovaquone has potent in vitro activity against Toxoplasma gondii, it is poorly absorbed after oral administration and shows poor therapeutic efficacy against TE. To overcome the low absorption of atovaquone, we prepared atovaquone nanosuspensions (ANSs) for intravenous (i.v.) administration. At concentrations higher than 1.0 μg/ml, ANS did not exert cytotoxicity and was as effective as free atovaquone (i.e., atovaquone suspended in medium) against T. gondii in freshly isolated peritoneal macrophages. In a new murine model of TE that closely mimics reactivated toxoplasmosis in immunocompromised hosts, using mice with a targeted mutation in the gene encoding the interferon consensus sequence binding protein, i.v.-administered ANS doses of 10.0 mg/kg of body weight protected the animals against development of TE and death. Atovaquone was detectable in the sera, brains, livers, and lungs of mice by high-performance liquid chromatography. Development of TE and mortality in mice treated with 1.0- or 0.1-mg/kg i.v. doses of ANS did not differ from that in mice treated orally with 100 mg of atovaquone/kg. In conclusion, i.v. ANSs may prove to be an effective treatment alternative for patients with TE. PMID:11353624

    Objective: To observe the therapeutic effects of segmental resection and decompression combined with joint prosthesis on continuous knee osteoarthritis (OA). Methods: A total of 130 patients with knee OA were selected and randomly divided into an observation group and a control group (n=65). The control group was treated by segmental resection in combination with joint prosthesis, and the observation group was treated by segmental resection and decompression combined with joint prosthesis. They were followed-up for three months. Results: All patients underwent successful surgeries during which no severe complications occurred. During the follow-up period, the overall effective rates of the observation group and the control group were 93.8% and 78.5% respectively, which were not statistically significantly different (p knee joint scores and functional scores of the two groups were similar, which evidently increased three months later, with significant intra-group and inter-group differences (p prosthesis gave rise to satisfactory short-term prognosis by effectively improving the flexion and extension of injured knee and by decreasing complications, thus being worthy of promotion in clinical practice.

    To determine the effects of alpha-mangostin on thioacetamide (TAA)-induced liver cirrhosis in rats. Male Wistar rats were divided into 3 groups and treated with intraperitoneal injections of TAA (200 mg/kg) 3 times per week for per week for 8, 12 and 16 weeks, respectively. One subgroup was left untreated whereas the other two were treated either with 100 mg/kg α-mangostin or vehicle alone (80% DMSO, 20% water), which were administered intraperitoneally 3 times per weekfor a total of4 weeks. The incidence offibrotic nodules on the liver and the serum levels of the liver enzymes aspartate transaminase (AST) and alanine transaminase (ALT) were measured. Moreover the liver cirrhosis-related genes expression and p53 protein level in liver were analyzed by quantitative reverse transcription PCR and Western blot analysis, respectively. Fibrotic nodules on the liver were formed upon treatment with TAA for 12 or 16 weeks. The nodules were then reduced by treatment with α-mangostin as compared to treatment with the vehicle DMSO. Moreover, the serum levels of the liver enzymes AST and ALT after treatment with α-mangostin decreased as compared to DMSO alone. The liver cirrhosis-related genes expression showed no significant differences, whereas the p53 protein level in liver showed that α-mangostin reduced risk of liver fibrosis through the decrease in p53 expression as compared to the TAA_DMSO treatment. The results suggest that α-mangostin has a beneficial therapeutic effect in the TAA liver cirrhosis model. Further investigations on mechanisms of α-mangostin as therapeutic agent should be determined.

    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.

    Full Text Available Aim: The purpose of this study was to compare the attention bias about tempting incentives related to opium materials in treated, addicted and normal people. Duration of consumption and treating were also considered. Method: In this causal-comparative study population was all addicted people who were referred to the rehabilitation offices, addiction treatment clinic, rebirthing centers and Narcotics Anonymous of East Azerbaijan. This study consisted of five groups of men, including addicted to opium materials which are divided into two groups namely: long consumption period and people with short consumption period, also, treated people including long term treated and short term treated, and a normal control group. Altogether, 103 selected people were studied. Sample groups were similar in terms of age, education, and sex. For measuring attention bias towards tempting stimuli related opiates, a words recognition test was used. This test included three subtests and one recognition test. The recognition scores for the three categories of words were measured. Results: The findings indicated that there was a difference in attention against opium material incentives between control group and the mild and severe consumers groups. Also there were significant differences between treated people with the short time distance and control group, and control group had less temptation and biases in comparison to the other groups. Finally, those who have mild consumption are threatened more in comparison with the control group. Conclusion: The findings have applied implications.

    To test whether three different intensive programs of treatment for neurotic and personality disorders are effective in decreasing neurotic symptoms and traits of neurotic personality and whether there are differences between them in clinical outcome. The sample consisted of 105 patients (83% female, mean age 35) diagnosed with neurosis and personality disorders that were treated in three therapeutic wards under routine inpatient conditions. The therapeutic programs are designed for patients with neurotic and personality disorders. They consist of 6-12 weeks of approximately 5 hours of eclectic group treatment (group psychotherapy, psychodrama, psychoeducation etc.). Participants filled in Symptoms' Questionnaire KS-II, and Neurotic Personality Questionnaire KON-2006 at the beginning and at the end of the course of psychotherapy. The treatment proved to be effective in diminishing neurotic symptoms (d Cohen = 0.56). More detailed analysis revealed that there was a significant interaction between the three analysed therapeutic wards and the effectiveness (12 = 0.09). The treatments offered in two institutions were effective (d Cohen = 0.80) while one of the programs did not lead to significant improvement of the patients. None of the therapeutic wards proved to be effective in changing the neurotic personality traits. There are significant differences in effectiveness of the intensive programs of treatment for neurotic and personality disorders. In the light of the literature, one can assume that the differences are more connected with the characteristics of therapeutic teams than with the methods used. The need for standard methods of effectiveness monitoring is discussed.

    Full Text Available Lifestyle therapy is an integral part of type 2 diabetes (T2D management, but there remains no consensus on an optimal diet. The objective of this study is to evaluate the efficacy of therapeutic fasting as a treatment for T2D. This case follows a male T2D patient treated at the Intensive Dietary Management Clinic in Scarborough, Ontario, over a 4-month period. The patient’s initial fasting regimen consisted of a 24-h fast, three times a week. Over the course of treatment, the patient gradually extended his fasting period, eventually fasting for 42 h, two to three times a week. By the end of treatment, the patient’s weight was reduced by 17.8% and his waist circumference was reduced by 11.0%. In addition, the patient’s glycated haemoglobin levels decreased from 7.7% to 7.2%, and he was able to completely discontinue his insulin treatment, despite over a decade of insulin usage. The patient did not find it difficult to adhere to the fasting schedule and did not experience any hypoglycaemic episodes or other significant adverse effects. These observations suggest that therapeutic fasting may be a viable treatment option for T2D patients.

    Full Text Available Psoriasis is resistant to treatment and it shows frequent relapse; systemic treatment is often associated with toxicities, and long-term safety data are lacking for most of the newer drugs like biologics. Moreover, some body areas such as hands, feet, intertriginous areas, scalp, and nails are even more resistant. Frequently, systemic treatments are necessary considering the higher psychological impact on the patient. There is a lack of agreement on the best therapeutic modalities in the management of psoriasis involving difficult-to-treat locations. At present, there are no Indian guidelines for these conditions. Available literature has been reviewed extensively on the treatment of psoriasis involving difficult-to-treat locations; level of evidence has been evaluated as per the Oxford Centre for Evidence-Based Medicine 2011 guideline, and therapeutic suggestions have been developed. Best care has been employed to consider socioeconomic, cultural, genetic, and ethnic factors to prepare a therapeutic suggestion that is appropriate and logical to be used among Indian population and people of similar ethnic and socioeconomic background.

    2017-07-01

    Adipose stem cell-conditioned medium may promote human dermal fibroblast (HDF) proliferation and migration by activating paracrine peptides during the re-epithelization phase of wound healing. Human antimicrobial peptide LL-37 is upregulated in the skin epithelium as part of the normal response to injury. The effects of conditioned medium (CM) from LL-37 treated adipose stem cells (ASCs) on cutaneous wound healing, including the mediation of fibroblast migration, remain to be elucidated, therefore the aim of the present study was to determine how ASCs would react to an LL-37-rich microenvironment and if CM from LL-37 treated ASCs may influence the migration of HDFs. The present study conducted migration assays with HDFs treated with CM from LL-37 treated ASCs. Expression of CXC chemokine receptor 4 (CXCR4), which controls the recruitment of HDFs, was analyzed at the mRNA and protein levels. To further characterize the stimulatory effects of LL-37 on ASCs, the expression of stromal cell-derived factor-1α (SDF-1α), a CXC chemokine, was investigated. CM from LL-37-treated ASCs induced migration of HDFs in a time- and dose-dependent manner, with a maximum difference in migration observed 24 h following stimulation with LL-37 at a concentration of 10 µg/ml. The HDF migration and the expression of CXCR4 in fibroblasts was markedly increased upon treatment with CM from LL-37-treated ASCs compared with CM from untreated ASCs. SDF-1α expression was markedly increased in CM from LL-37 treated ASCs. It was additionally observed that SDF-1α blockade significantly reduced HDF migration. These findings suggest the feasibility of CM from LL-37-treated ASCs as a potential therapeutic for human dermal fibroblast migration.

    Therapeutic application of pharmacologically active proteins requires advanced drug delivery systems for stabilizing their activity and preventing denaturation during storage and patient treatment. Depending on their clinical target, controlled drug release is often required to achieve the intended therapeutic effect. In this context, electrospun nanofibers gained considerable attention. However, even though immediate drug release from such fibers can easily be realized, fiber mat fabrication providing long-term controlled protein release still bares challenges.In this study, lysozyme was encapsulated in poly(vinyl alcohol) fibers followed by post-modification with MeOH, glutaraldehyde vapor, or UV light. Subsequently, a systematic investigation of the effect of these post-modification treatments on the physicochemical properties of the fibers and the stability and release kinetics of lysozyme was performed. MeOH treatment did not affect lysozyme release kinetics compared to untreated fibers, whereas glutaraldehyde vapor and UV light treatment prolonged the drug release. Infrared spectroscopy revealed cross-linking of the polymer by glutaraldehyde vapor, which reduced the lysozyme release from the fibers. Further, protein activity was significantly reduced for fibers treated with glutaraldehyde vapor and UV light. In addition, reduced viability was identified for cells in contact with glutaraldehyde vapor-treated fibers and, to a lesser extent, for UV light-treated fibers, whereas MeOH-treated fibers did not affect cell viability. These results elucidated the effects of fiber post-modification on the release kinetics, activity, and biocompatibility of protein drugs and can serve as guidance for rational development of nanomedicines for safe and effective therapeutic delivery of natural proteins.

    The effects of water treated with an electromagnetic field (EMF) were investigated on two biological systems, humans and plants. Purified de-ionised water was treated by (1) boiling, (2) exposure to microwave radiation, and (3) low frequency electromagnetic oscillation molecular resonance effect technology (MRET), before being used to prepare media for culturing human peripheral blood mononuclear cells (PBMC) from three healthy females. Our results indicated that PBMC culture in MRET-activated medium showed significantly less oxidative metabolism when compared to media prepared from other types of water. As for the effects on soybean, our results indicated that both MRET- and microwave-treated water greatly enhanced the length of the root. These results suggested that electromagnetic-treated water can have diverse biological effects on both animal and plant cells. Since these effects are related to the 'Memory of Water', hypothesis which has been suggested as an explanation of the action of high homeopathic dilutions, our finding warrant a further investigation on the mechanisms of various types of physically conditioned water on specific cellular activities.

    Understanding the reasoning behind the choice of medicinal plants is relevant for both pharmacological and ethnobotanical quantitative studies. In this study, we analyze how the traditional medical system influences the choice of medicinal plants in a Mexican indigenous population. The study area was San Miguel Tulancingo, Oaxaca, Mexico, and the studied people the Rru ngigua (or Chocholtecs), an Otomangue group with only a few hundred speakers remaining. Through in-depth and repeated interviews of four traditional healers and ethnobotanical collections, we identified, described and classified the medicinal plants, the nosological units, the therapeutic procedures and the reasoning behind medicinal plant and treatment choice. The hot-cold system, which considers illness to be a result of humoral imbalance, strongly influences treatment choice. "Hot" plants are used mainly to treat "cold" diseases, and vice versa. With some variation, plants are selected mainly for this hot-or-cold property, and the specific plant species is often not very relevant. In addition, many plants are associated with specific healing procedures, such as sweat baths. The procedures, in turn, may be used to treat various diseases. The study shows that the relationship between medicinal plants and treated diseases is complex and indirect in most cases. It is strongly influenced by the hot-cold concept and by therapeutic procedures. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    The photothermal properties of gold nanoparticles (GNPs) are promising therapeutic modality for cancer. The study objective is to evaluate the therapeutic effect of the prepared PEGylated gold nano-semicubes (PEG-GNSCs) in skin cancer. The synthesized PEG-GNSCs were intermediate between cubic and rod shapes (low aspect ratio- rods). In vitro toxicity was investigated in human skin melanoma Sk-Mel-28 cells, and skin squamous cell carcinoma was induced in CD1 mice by dimethylbenzanthracene (DMBA) and 12-O-tetradecanoyl-phorbol-13-acetate (TPA). The calculated IC 50 in Sk-Mel-28 cells was 3.41μg/ml of PEG-GNSCs, in presence of laser exposure. Photothermal therapy using laser-stimulated PEG-GNSCs resulted in inhibited volume of skin tumors. Our findings indicated that the inflammatory mediators, nitric oxide and cycloxygenase-2, were inhibited in mice after being treated with low and high doses of PEG-GNSCs, accompanied with laser exposure. However, the tumor necrosis factor -α was markedly elevated, while there was no change in 5-lipoxygenase. The pro-angiogenic factor vascular endothelial growth factor was inhibited, while histone acetylation and apoptosis were induced in tumor-bearing groups, after being treated with laser-stimulated PEG-GNSCs. The present study indicated the promising photothermal therapeutic effect of laser-stimulated PEG-GNSCs as an effective modality to inhibit the tumor growth, the angiogenesis and partially the inflammation.

    We studied the long-term antianginal and anti-ischemic effects of two dosage regimens designed to prevent tolerance to transdermal nitroglycerin (TNTG): (1) 10 mg TNTG applied for 16 h with a 'nitrate-free' interval of 8 h; (2) 10 mg TNTG applied for 16 h followed by a 'nitrate-low' interval of 5 mg applied for 8 h. 129 patients completing a 3-month study period were evaluated by repeated exercise tests. Both regimens significantly increased maximum exercise duration at 3 months, from 699.1 +/- 23.4 to 833 +/- 21.9 s and from 686.1 +/- 20 to 789.6 +/- 22.6 s, respectively, reduced the number of patients with 1 mm S-T segment depression and increased the time duration to 1 mm S-T segment depression. Marked reductions in anginal attacks was observed in both groups: from 6.5 to 0.15 attacks per week and from 6.0 to 0.15 attacks per week, respectively. No statistically significant differences were found between the groups, and both regimens were well tolerated. In conclusion, our results demonstrate sustained antianginal efficacy, without tolerance, of either 'nitrate-free' of 'nitrate-low' interval therapy with transdermal nitroglycerin.

    2015-09-01

    Pathological nighttime fears in children have been little studied. However, this disorder is commonly encountered in medical consultations and is discomforting and dysfunctional for both the child and the family. Most nighttime fears are part and parcel of normal development, and emanate from increasingly sophisticated cognitive development in the growing child. Thus, most children report a variety of coping strategies generally helpful in reducing their anxiety, which resolves spontaneously in the growing child. Nevertheless, in about 10% of children, nighttime fears are related to one or more anxiety disorders according to Diagnostic and Statistical Manual of Mental Disorders criteria. Then, it is estimated that severe nighttime fears and sleep problems occur in 20-30% of children. This problem is not transient and has to be treated. This study aims to review clinical features of nighttime fears and possible treatments for these patients and their families. This systematic review follows the preferred reporting items for systematic reviews and meta-analysis (PRISMA) statement guidelines. Two databases (Medline and Web of Science) were searched combining the search terms: nighttime fears AND children. English and French languages were imposed. There were no publication date or publication status limitations. Pathological nighttime fears are responsible for emotional (crying, panic, tantrums at bedtime, loss of confidence, self-disparaging negative statements, and feeling of social embarrassment) and behavioral (wandering alone in the house at night, calls for parental or sibling comfort, bed sharing with parents or siblings, light source at night, refusal to go to the toilet alone at night) disturbances. This leads to a poor quality of sleep interfering with school learning, and also affects social development and family functioning. A full assessment has to be made to eliminate organic causes, have a baseline functioning, and search for comorbid anxiety diseases

  9. Homeopathy and systematics: a systematic analysis of the therapeutic effects of the plant species used in homeopathy.

    Science.gov (United States)

    Bharatan, V

    2008-07-01

    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 Introduction Experimental studies conducted in young animals show that therapeutic ultrasound (TUS has been successfully used to shorten the healing time of bone fractures. However, they were not found in the literature, studies comparing the effect of different intensities of UST in aged animals. Objective To test the efficacy of intensity 1.0 W/cm2 and of 0.5 W/cm2 in the consolidation of experimental fracture of the tibia from aged Wistar rats. Materials and methods Three groups of 15 month old rats were submitted to a midshaft osteotomy of the tibia and then, the hind member was immobilized with a metal splint and plaster of Paris, wrapping the knee and ankle joint. One group (L, received ultrasound at 0.5 W/cm2; the other group (I, were exposed to ultrasound at 1.0 W/cm2. One control group (C, did not receive the ultrasound. Fifteen animals (five from each group were euthanatized at the end of the first week and fifteen (five from each group at the end of the third week. The progress of the fracture healing was performed for each group by morphometric analysis of histological sections of the fracture region. Results and conclusion The results showed that fractures treated with ultrasound at 1.0 W/cm2 healed significantly faster than did the fractures treated with ultrasound at 0.5 W/cm2 and the control.

    The radioprotector S-2-(3-aminopropylamino)ethylphosphorothioic acid (WR-2721) was evaluated for its ability to protect against cytoxan-induced mutagenesis at the hypoxanthine-guanine phosphoribosyl transferase (hprt) locus in mouse splenocytes under conditions that would not interfere with the therapeutic effectiveness of cytoxan in the treatment of fibrosarcoma lung tumors. Mutations at the hprt locus increase in frequency as a function of the dose of cytoxan used. With a spontaneous mutation frequency in C3H mice of 1.5 {times} 10{sup {minus}6}, mutation frequencies increased from 6.2 {times} 10{sup {minus}6} to 2.0 {times} 10{sup {minus}5} as the dose of cytoxan increased from 50 to 200 mg/kg. C3H male mice were injected in their tail veins with 3.5 {times} 10{sup 5} viable fibrosarcoma (FSa) cells. This protocol gave rise to an average of 68 tumor colonies per mouse. Four days following injection animals were treated with cytoxan at a dose of 100 mg/kg, which gave rise to significant tumor cell killing and a reduction in tumor colony number to less than an average of one per animal. WR-2721 at a concentration of 100 mg/kg did not affect on cytoxan`s therapeutic effectiveness. However, a 100 mg/kg dose of WR-2721 was effective in reducing the cytoxan induced hprt mutation frequency in mice from 160 to 35 per 10{sup 5} viable cells regardless of whether it was administered 30 min before or 2 h following cytoxan treatment.

    Laboratory effectiveness tests have been developed for four classes of oil spill treating agents: solidifiers, demulsifying agents, surface-washing agents and dispersants. Several treating agent products in these four categories have been tested for effectiveness. The aquatic toxicity of these agents is an important factor and has been measured for many products. These results are presented. Solidifiers or gelling agents solidify oil. Test results show that solidifiers require between 16% and 200% of agent by weight compared to the oil. De-emulsifying agents or emulsion breakers prevent the formation of or break water-in-oil emulsions. Surfactant-containing materials are of two types, surface-washing agents and dispersants. Testing has shown that effectiveness is orthogonal for these two types of treating agents. Tests of surface washing agents show that only a few agents have effectiveness of 25 to 55%, where this is defined as the percentage of oil removed from a test surface. Dispersant effectiveness results using the swirling flask test are reported. Heavy oils show effectiveness values of about 1%, medium crudes of about 10%, light crude oils of about 30% and very light oils of about 90%

    2016-01-01

    Full Text Available Telomeres, the protective ends of linear chromosomes, shorten throughout an individual’s lifetime. Telomere shortening is a hallmark of molecular aging and is associated with premature appearance of diseases associated with aging. Here, we discuss the role of telomere shortening as a direct cause for aging and age-related diseases. In particular, we draw attention to the fact that telomere length influences longevity. Furthermore, we discuss intrinsic and environmental factors that can impact on human telomere erosion. Finally, we highlight recent advances in telomerase-based therapeutic strategies for the treatment of diseases associated with extremely short telomeres owing to mutations in telomerase, as well as age-related diseases, and ultimately aging itself.

    Cardenas, Diana D; Emir, Birol; Parsons, Bruce

    2015-05-01

    In 2 large-scale, placebo-controlled trials, pregabalin improved both pain and pain-related sleep interference in patients with neuropathic pain due to spinal cord injury (SCI). In both trials, pregabalin found statistically significant improvement compared with placebo after 1 week of treatment. However, the effects of pregabalin in the days immediately after initiation of treatment are unknown. The purpose of the present analysis was to determine timing of pregabalin's therapeutic effect in the days after initiation of treatment. Data were derived from 2 trials of pregabalin in patients with SCI-related neuropathic pain. Each day patients rated severity of pain and pain-related sleep interference over the past 24 hours on a scale from 0 to 10, with higher scores indicating greater severity. To quantify timing of therapeutic effect, we compared (pregabalin [vs] placebo) daily average pain and pain-related sleep interference scores over the first 14 days of treatment. Significant improvement was defined as the first day, of ≥2 consecutive days, that pregabalin significantly (P pain and pain-related sleep interference score among patients with a clinically meaningful and sustained response (≥30% improvement from baseline to end point) by using a time-to-event analysis method. Kaplan-Meier analyses were used to estimate the median (or 25th quartile) time (in days) required to achieve a ≥1-point improvement, among these responders, in pain and pain-related sleep interference scores. Comparisons between pregabalin and placebo were made with a log-rank test. In both trials, significant improvement of pain and pain-related sleep interference occurred within 2 days of initiating treatment with pregabalin. Among patients reporting a clinically meaningful and sustained response to treatment (patients with ≥30% improvement from baseline to end point), the time to a ≥1-point improvement of pain and pain-related sleep interference occurred significantly earlier among

    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.

    To explore the therapeutic role of globular adiponectin (gAd) in high-fat diet/streptozotocin (STZ)-induced type 2 diabetic rats with nonalcoholic fatty liver disease (NAFLD). Seven rats were fed a basic diet (normal control group; NC) during the experiment. Experimental rats (14 rats) were given a high-fat diet for 4 wk and were then injected with STZ to induce type 2 diabetes mellitus (T2DM) and NAFLD. Half of the T2DM/NAFLD rats were randomly injected intraperitoneally with gAd for 7 d (gAd-treated group), while the other 7 rats (T2DM/NAFLD group) received 0.9% saline. Plasma biochemical parameters and insulin concentrations were measured. Liver histopathology was examined by hematoxylin-eosin staining. Insulin receptor expression in the liver was analyzed by immunohistochemical staining, Western blot and quantitative real-time reverse transcription polymerase chain reaction analysis. Compared to the control group, the T2DM/NAFLD group had increased levels of glucolipid and decreased levels of insulin.

    Based on the movement-pedagogical concept of Feldenkrais and the findings-of disturbed body perception by eating disordered patients this research aimed at studying the therapeutical effects of the Feldenkrais Method "Awareness through Movement" with eating disorder patients, 15 eating disordered patients treated at the Roseneck hospital for behavioural medicine rated-by means of a questionnaire consisting of scales of the Body Cathexis Scale (BCS), the Body Parts Satisfaction Scale (BPSS), the questionnaire for body perception (Fragebogen zum Körpererleben; FKE), the Emotion inventory (Emotionalitätsinventar; EMI-B), the Anorexia-Nervosa-Inventory for Self-rating (ANIS) and the Eating Disorder Inventory-2 (EDI)-various aspects of their eating disorder before and after participating in a nine hour course of the Feldenkrais Method. The data of these patients were compared to those of the members of a control group, also consisting of 15 eating disordered patients who did not participate in a Feldenkrais course. The participants of the Feldenkrais-course showed increasing contentment with regard to problematic zones of their body and their own health as well as concerning acceptance and familiarity with their own body. Other results were a more spontaneous, open and self-confident behaviour, the decrease of feelings of helplessness and decrease of the wish to return to the security of the early childhood, which indicates the development of felt sense of self, self-confidence and a general process of maturation of the whole personality. The outcome points to the therapeutical effectiveness of the Feldenkrais Method with eating-disorder patients within a multimodal treatment program.

    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.)

The efficacy of the prepared rivastigmine liposomes (RLs in comparison to rivastigmine solution (RS was assessed in an aluminium chloride (AlCl3-induced Alzheimer’s model.Methods: Liposomes were prepared by lipid hydration (F1 and heating (F2 methods. Rats were treated with either RS or RLs (1 mg/kg/day concomitantly with AlCl3 (50 mg/kg/day.Results: The study showed that the F1 method produced smaller liposomes (67.51 ± 14.2 nm than F2 (528.7 ± 15.5 nm, but both entrapped the same amount of the drug (92.1% ± 1.4%. After 6 hours, 74.2% ± 1.5% and 60.8% ± 2.3% of rivastigmine were released from F1 and F2, respectively. Both RLs and RS improved the deterioration of spatial memory induced by AlCl3, with RLs having a superior effect. Further biochemical measurements proved that RS and RLs were able to lower plasma C-reactive protein, homocysteine and asymmetric dimethylarginine levels. RS significantly attenuated acetylcholinesterase (AChE activity, whereas Na+/K+-adenosine triphosphatase (ATPase activity was enhanced compared to the AlCl3-treated animals; however, RLs succeeded in normalization of AChE and Na+/K+ ATPase activities. Gene-expression profile showed that cotreatment with RS to AlCl3-treated rats succeeded in exerting significant decreases in BACE1, AChE, and IL1B gene expression. Normalization of the expression of the aforementioned genes was achieved by coadministration of RLs to AlCl3-treated rats. The profound therapeutic effect of RLs over RS was

    We report the successful treatment of autoimmune hypoglycemia in an 82-year-old non-diabetic Caucasian male with hydrothermally modified slow release corn starch, a product which is used in other conditions associated with hypoglycemia, most typically glycogen storage disease type I. An 82-year-old-Caucasian male presented with recurrent spontaneous hypoglycemia as low as 30 mg/dl following in-patient treatment for community acquired pneumonia. During a fasting-test, symptomatic hypoglycemia occurred. Plasma concentrations of c-peptide and insulin were considerably elevated. Autoimmune hypoglycemia was confirmed by the presence of insulin autoantibodies. While dietary restriction alone did not result in sufficient glucose control in this patient with autoimmune hypoglycemia, treatment with hydrothermally modified slow release corn starch led to stable euglycemia. This easy, well tolerated and non-invasive treatment may constitute a new therapeutic option for hypoglycemia in patients with autoimmune hypoglycemia who do not achieve sufficient control of hypoglycemia by dietary restriction alone.

    Local ablative therapies such as stereotactically guided single-dose radiotherapy or helical intensity-modulated radiotherapy (tomotherapy) with high single-doses are successfully applied in many centers in patients with liver metastasis not suitable for surgical resection. This study presents results from more than 10 years of clinical experience and evaluates long-term outcome and efficacy of this therapeutic approach. From 1997 to 2009 a total of 138 intrahepatic tumors of 90 patients were irradiated with single doses of 17 to 30 Gy (median dose 24 Gy). Median age of the patients was 64 years (range 31–89 years). Most frequent underlying tumor histologies were colorectal adenocarcinoma (70 lesions) and breast cancer (27 lesions). In 35 treatment sessions multiple targets were simultaneously irradiated (up to four lesions at once). Local progression-free (PFS) and overall survival (OS) after treatment were investigated using uni- and multiple survival regression models. Median overall survival of all patients was 24.3 months. Local PFS was 87%, 70% and 59% after 6, 12 and 18 months, respectively. Median time to local progression was 25.5 months. Patients with a single lesion and no further metastases at time of RT had a favorable median PFS of 43.1 months according to the Kaplan-Meier estimator. The type of tumor showed a statistical significant influence on local PFS, with a better prognosis for breast cancer histology than for colorectal carcinoma in uni- and multiple regression analysis (p = 0.05). Multiple regression analysis revealed no influence of planning target volume (PTV), patient age and radiation dose on local PFS. Treatment was well tolerated with no severe adverse events. This study confirms safety of SBRT in liver lesions, with 6- and 12 months local control of 87% and 70%. The dataset represents the clinical situation in a large oncology setting, with many competing treatment options and heterogeneous patient characteristics

  5. Survivin counteracts the therapeutic effect of microtubule de-stabilizers by stabilizing tubulin polymers

    Full Text Available Abstract Background Survivin is a dual function protein. It inhibits the apoptosis of cells by inhibiting caspases, and also promotes cell growth by stabilizing microtubules during mitosis. Over-expression of survivin has been demonstrated to induce drug-resistance to various chemo-therapeutic agents such as cisplatin (DNA damaging agent and paclitaxel (microtubule stabilizer in cancers. However, survivin-induced resistance to microtubule de-stabilizers such as Vinca alkaloids and Combretastatin A-4 (CA-4-related compounds were seldom demonstrated in the past. Furthermore, the question remains as to whether survivin plays a dominant role in processing cytokinesis or inhibiting caspases activity in cells treated with anti-mitotic compounds. The purpose of this study is to evaluate the effect of survivin on the resistance and susceptibility of human cancer cells to microtubule de-stabilizer-induced cell death. Results BPR0L075 is a CA-4 analog that induces microtubule de-polymerization and subsequent caspase-dependent apoptosis. To study the relationship between the expression of survivin and the resistance to microtubule de-stabilizers, a KB-derived BPR0L075-resistant cancer cell line, KB-L30, was generated for this study. Here, we found that survivin was over-expressed in the KB-L30 cells. Down-regulation of survivin by siRNA induced hyper-sensitivity to BPR0L075 in KB cells and partially re-stored sensitivity to BPR0L075 in KB-L30 cells. Western blot analysis revealed that down-regulation of survivin induced microtubule de-stabilization in both KB and KB-L30 cells. However, the same treatment did not enhance the down-stream caspase-3/-7 activities in BPR0L075-treated KB cells. Translocation of a caspase-independent apoptosis-related molecule, apoptosis-inducing factor (AIF, from cytoplasm to the nucleus was observed in survivin-targeted KB cells under BPR0L075 treatment. Conclusion In this study, survivin plays an important role in the

    In this study, we report a method for the suppression of Escherichia coli (E. coli) vitality by means of therapeutic ultrasound irradiation (USI) using biocompatible silicon nanoparticles as cavitation sensitizers. Silicon nanoparticles without (SiNPs) and with polysaccharide (dextran) coating (DSiNPs) were used. Both types of nanoparticles were nontoxic to Hep 2 cells up to a concentration of 2 mg/mL. The treatment of bacteria with nanoparticles and application of 1 W/cm 2 USI resulted in the reduction of their viabilities up to 35 and 72% for SiNPs and DSiNPs, respectively. The higher bacterial viability reduction for DSiNPs as compared with SiNPs can be explained by the fact that the biopolymer shell of the polysaccharide provides a stronger adhesion of nanoparticles to the bacterial surface. Transmission electron microscopy (TEM) studies showed that the bacterial lipid shell was partially perforated after the combined treatment of DSiNPs and USI, which can be explained by the lysis of bacterial membrane due to the cavitation sensitized by the SiNPs. Furthermore, we have shown that 100% inhibition of E. coli bacterial colony growth is possible by coupling the treatments of DSiNPs and USI with an increased intensity of up to 3 W/cm 2 . The observed results reveal the application of SiNPs as promising antimicrobial agents.

    Skingley, A; Vella-Burrows, T

    To identify how music and singing may be used therapeutically by nurses in caring for older people. A multimethod approach was taken, comprising a search of the Cumulative Index of Nursing and Allied Health Literature (CINAHL) and Medline databases, and the extraction of relevant articles from three existing reviews. Two reviews and 16 research reports were identified, the majority of which were intervention studies. All the studies reported benefits from music or singing for older people. Positive findings related to dementia, specific disorders (osteoarthritis pain, post-operative delirium, sleep difficulties, chronic obstructive pulmonary disease), and older people living at home. Recommendations for nursing were made, although there is a need for clarification on how nursing interventions should be implemented. The evidence base to support the benefits of music and singing is increasing, and it is suggested that nurses may contribute to appropriate interventions and referrals. There is a need for further research, both to support these findings and to explore the nursing role in relation to providing music and singing therapies.

Therefore, patients were classified according to the Cohen classification or web thickness, and the recurrence rates were compared. The distribution of recurrence rates for Cohen type 1 ~ 4 were 28.6, 16.7, 33.3, and 40%, respectively. The difference was not statistically significant (P = 0.461). When classified by web thickness, only 2 of 27 (7.41%) thin type cases relapsed whereas 8 of 9 (88.9%) cases in the thick group reformed webs (P web thickness rather than the Cohen grades. Endoscopic lysis and keel placement is only effective for cases with thin glottic webs. Patients with thick webs should be treated by other means.

    Full Text Available The aim of this study was to evaluate effects of aqueous extract from Cortex acanthopanacis (CAE on osteoporosis rats induced by ovariectomy (OVX using aqueous extract from Folium Epimedii (FEE as positive control agent. Three-month-old female rats that underwent OVX were treated with CAE. After 12 weeks, bone mineral density (BMD and indices of bone histomorphometry of tibia were measured. Levels of protein and mRNA expression of osteoprotegerin (OPG and receptor activator of nuclear factor kappa-B ligand (RANKL in tibia were evaluated. In addition, the serum concentrations of osteocalcin (OC, interleukin-1 beta (IL-1β, interleukin-6 (IL-6, calcitonin (CT, and parathyroid hormone (PTH were determined. Administration of CAE significantly prevented OVX-induced rats from gain of the body weight. Treatment with CAE increased bone mass remarkably and showed a significant inhibitory effect on bone resorption by downregulating significantly the expression of RANKL in tibia of OVX rats. Meanwhile, treatment of CAE significantly reduced serum level of IL-1β and increased level of CT in OVX rats. This suggests that CAE has the potential to be used as an alternative therapeutic agent for postmenopausal osteoporosis.

    Full Text Available Since a therapy's full positive effect and possible adverse effects are individual and not predictable for every single patient, scientists have been searching for methods to predict optimal effects of a therapy. This pilot study investigated the applicability of the “kinesiology muscle test” as a prognostic tool regarding effectiveness in a defined therapeutic procedure. Each of 11 test persons with elevated total cholesterol values received a naturopathic drug supposed to lower cholesterol level on a daily basis for eight consecutive weeks. Prior to treatment the “kinesiology muscle test” was performed, where the patient's ability to maintain a flexed position in a selected joint was evaluated. The resistance created by the patient against the tester's pressure was monitored. Being in touch with healthful or unhealthful chemical substances may, according to the kinesiology literature, increase or decrease this resistance. For testing purposes, the drug was placed onto the patients' skin. The ability of the brachioradial muscle to resist the tester's pressure was determined on a subjective scale (0-100%. The Pearson product-moment correlation coefficient between four variables (total cholesterol value before therapy, total cholesterol value after therapy, difference of total cholesterol values before and after therapy, prior to treatment kinesiology testing was chosen. A significant correlation between the difference of total cholesterol values before-after and the prior to treatment test was found, as well as a significant correlation between the total cholesterol values after therapy and the prior to treatment kinesiology test.

    Abstract Methane production from co‐digestion of dairy manure and waste milk, milk from cows treated with antibiotics for mastitis, was tested in a 2 × 4 factorial design. Four different waste milk percentages (w/w): 0% (SM), 10% (SMWM10), 20% (SMWM20) and 30% (SMWM30), were tested with two slurry percentages (w/w): 50% (A) and 25% (B) and the rest being manure at 55°C for 12 days in batch digesters. The results analyzed using a Gompertz model showed SMWM10 produced the highest methane production potential (Pm)/g volatile solids added followed by SM in both A and B. This Pm of SMWM10 in A and B was statistically non‐significant (P > 0.05). More than 96% of cefazolin‐resistant bacteria and 100% of multi‐drug‐resistant bacteria reductions were observed in all the treatments. Inclusion of waste milk at 10% in single stage digester enhances the methane production from dairy manure and could offer added benefit of waste milk treatment and disposal. PMID:27169788

    2011-02-01

    The use of virtual reality to treat anxiety disorders in adults is gaining popularity and its efficacy is supported by numerous outcome studies. Similar research for children is lagging behind. The outcome studies on the use of virtual reality to treat anxiety disorders in children currently address only specific phobias, and all of the available trials are reviewed in this article. Despite the limited number of studies, results are very encouraging for the treatment of school and spider phobias. A study with adolescents suggests that, at least for social anxiety, exposure stimuli would be more effective if they were developed specifically for younger populations. Virtual reality may not increase children's motivation towards therapy unless their fearful apprehension is addressed before initiating the treatment.

    Sulfur mustard (SM) is a strong blistering, highly reactive, lipophilic chemical war agent that causes injury in different organs including the skin, eyes, and respiratory tract. The Eyes are especially susceptible to the consequences of SM poisoning because of the aqueous and mucosal nature of conjunctiva and cornea. DNA alkylation and depletion of glutathione, are the most important mechanisms of SM action in the eye injuries. Acute clinical symptoms are including decrease in visual acuity, dryness, photophobia, blepharospasm, conjunctivitis, and complaints of foreign body sensation and soreness that gradually progress to severe ocular pain. Corneal abrasions, ulcerations, vesication, and perforations are common corneal consequences in SM injured victims. Appearance of chronic symptoms has been reported as chronic inflammation of the corneal and conjunctival vasculature, ischemia, lipid and cholesterol deposition, scarring in cornea, corneal thinning, opacification and perforation of the cornea, limbal stem cell deficiency (LSCD), and neovascularization. Different medical and surgical protocols have been documented in the management of SM-induced ocular injuries, including preservative-free artificial tears, topical steroids and antibiotic, mydriatic, antiglaucoma drops, therapeutic contact lenses, dark glasses and punctal plugs/cauterization, N-acetylcysteine, tarsorrhaphy, amniotic membrane transplantation, stem cell transplantation, and corneal transplantation. New drugs such as resolvin E1, topical form of essential fatty acids, thymosin β4, 43 amino-acid polypeptides, topical form of curcumin, newly formulated artificial tears, diquafosol, rebamipide, tretinoin, and oral uridineseems to be beneficial in the management of ocular lesion associated with sulfur mustard poisoning. Further studies are needed to approve these drugs in SM victims. J. Cell. Biochem. 118: 3549-3560, 2017. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

However, LA is primarily used in the treatment of previously-mentioned severe forms of dyslipidemia. FH patients are particularly prone to coronary ischemic events necessitating a tailored, intensive, efficient, continuous, and unceasing form of treatment. Obviously, a therapeutic approach exclusively relying on existing accessible medications would not lead to preferred clinical outcomes. The above reported clinical examples clearly suggest what differences exist between the non-selective and selective apheresis techniques as far as different pathologies exhibiting affinity are concerned. In particular, the clinical presentation, emergency or not, greatly affects the use of a given extracorporeal technique. However, depending upon the indication, a selective technique not usually utilized in emergency, such as selective dextran sulfate cellulose LA was recently suggested to treat acutely preeclampsia, where targeted therapies to stabilize the clinical manifestations and prolong

    Purpose: Radical radiotherapeutic management of vulvar cancer often incorporates brachytherapy as a portion of the treatment regimen. However, few studies using this modality alone to manage vulvar cancer have been published. Methods and Materials: Thirty four patients were treated with iridium-192 ( 192 Ir) brachytherapy for vulvar cancer between 1975 and 1993 at Centre Alexis Vautrin. Twenty-one patients were treated at first presentation when surgery was contraindicated or declined. Of these patients, 12 had International Federation of Gynecology and Obstetrics Classification Stage III or IV disease, 8 were Stage II, 1 was Stage I, and 1 was Stage 0. Thirteen patients were treated for recurrent disease. Paris system rules for implantation and dose prescription were followed. The median reference dose was 60 Gy (range 53 to 88 Gy). At the time of analysis, 10 of 34 patients were alive. Median follow-up in these 10 patients was 31 months (range: 21 months to 107 months). Fourteen of the 24 deaths were from causes other than vulvar cancer. Results: Kaplan-Meier actuarial 5-year local control was 47% (95% confidence interval (CI) = 23 to 73%) and 5-year actuarial loco-regional control was 45% (95% CI = 21 to 70%). Kaplan-Meier actuarial 5-year disease-specific survival was 56% (95% CI = 33 to 76%) and actuarial 5-year survival was 29% (95% CI = 15 to 49%). Median time to death was 14 months. Subset analysis revealed a higher actuarial 5-year local control in patients treated at first presentation than those treated for recurrence (80 vs. 19%, log rank, p = 0.04). Similarly, actuarial 5-year loco-regional control was higher in patients treated at first presentation (80 vs. 16%, log rank, p 0.01). The two groups did not differ significantly in disease-specific or overall survival. The actuarial 5-year disease specific survival of 56% is somewhat less than the expected 5-year disease-specific survival after surgery in a group having a similar proportion of early stage

    Depression is a very common mood disorder, resulting in a loss of social function, reduced quality of life and increased mortality. Music interventions have been shown to be a potential alternative for depression therapy but the number of up-to-date research literature is quite limited. We present a review of original research trials which utilize music or music therapy as intervention to treat participants with depressive symptoms. Our goal was to differentiate the impact of certain therapeutic uses of music used in the various experiments. Randomized controlled study designs were preferred but also longitudinal studies were chosen to be included. 28 studies with a total number of 1,810 participants met our inclusion criteria and were finally selected. We distinguished between passive listening to music (record from a CD or live music) (79%), and active singing, playing, or improvising with instruments (46%). Within certain boundaries of variance an analysis of similar studies was attempted. Critical parameters were for example length of trial, number of sessions, participants' age, kind of music, active or passive participation and single- or group setting. In 26 studies, a statistically significant reduction in depression levels was found over time in the experimental (music intervention) group compared to a control ( n = 25) or comparison group ( n = 2). In particular, elderly participants showed impressive improvements when they listened to music or participated in music therapy projects. Researchers used group settings more often than individual sessions and our results indicated a slightly better outcome for those cases. Additional questionnaires about participants confidence, self-esteem or motivation, confirmed further improvements after music treatment. Consequently, the present review offers an extensive set of comparable data, observations about the range of treatment options these papers addressed, and thus might represent a valuable aid for future

    Full Text Available Gaucher disease type 1 is caused by the defective activity of the lysosomal enzyme, acid beta-glucosidase (GCase. Regular infusions of purified recombinant GCase are the standard of care for reversing hematologic, hepatic, splenic, and bony manifestations. Here, similar in vitro enzymatic properties, and in vivo pharmacokinetics and pharmacodynamics (PK/PD and therapeutic efficacy of GCase were found with two human GCases, recombinant GCase (CHO cell, imiglucerase, Imig and gene-activated GCase (human fibrosarcoma cells, velaglucerase alfa, Vela, in a Gaucher mouse, D409V/null. About 80+% of either enzyme localized to the liver interstitial cells and <5% was recovered in spleens and lungs after bolus i.v. injections. Glucosylceramide (GC levels and storage cell numbers were reduced in a dose (5, 15 or 60 U/kg/wk dependent manner in livers (60-95% and in spleens ( approximately 10-30%. Compared to Vela, Imig (60 U/kg/wk had lesser effects at reducing hepatic GC (p = 0.0199 by 4 wks; this difference disappeared by 8 wks when nearly WT levels were achieved by Imig. Anti-GCase IgG was detected in GCase treated mice at 60 U/kg/wk, and IgE mediated acute hypersensitivity and death occurred after several injections of 60 U/kg/wk (21% with Vela and 34% with Imig. The responses of GC levels and storage cell numbers in Vela- and Imig-treated Gaucher mice at various doses provide a backdrop for clinical applications and decisions.

    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.

    The effect of taurin (200mg/kg) in combination with insulin (0.2 IU/kg) on the repair of hormonal activity and of carbohydrate metabolism in an experimentally released radiation sickness was examined. White rats of both sexes weighting 180-200 g were irradiated with a gamma-unit GUM-Co-50 with 700 rad, that corresponds to LDsub(70/30). The preparations were simultaneously administered intraperitoneally every other day altogether 8 times from the 5th day after irradiation. Survival rate in the groups of treated animals was by about 27% higher than in the control. With the administration of therapeutic preparations a repair of the insulin-like plasma activity to the normal levels and a considerable inhibition of liver phosphorylase activity could be observed. Different from insulin action alone a combined use of insulin and taurin led to decrease in blood level of 11-oxycorticosteroids the metabolism of which being essentially impaired by irradiation to the normal value. The restoration of correlation between hormonal activity of adrenal cortex and of the insular apparatus favoured glycogen reproduction in the liver and the decrease in blood-sugar level. Experiments with intact animals as well as in vitro experiments reveal that taurin acts insulin-like

    The aim of the present study is to evaluate the efficacy of slow zinc (Zn) release from β-tricalcium phosphate powder (ZnTCP) containing 10 mol% Zn on rats with thermal burns. The first-aid tapes were contained zinc sulfate (ZnSO4) solution, ZnTCP suspensions or zinc oxide ointment. After thermal burn treatments were performed on Zn-deficient rats, the groups D1, D2 and D3 were treated with tapes containing ZnTCP, ZnSO4 and zinc oxide ointment. The effects of the tapes on wound area, plasma Zn levels and alkaline phosphatase activity (Alp) were investigated. The wound area profiles of all rat groups could be separated into before and after the scab formation at around day 6. The area under the curve (Aw-AUC) for wound area profiles, therefore, was evaluated as an index of therapeutic scores for the thermal wound. The order of Aw-AUC was D3>C>D2>D1. The degree of expansion at the initial stage by thermal burns of group D1 was the lowest and that of group D2 was the highest, and the order was D1thermal burns.

    CD1d-restricted natural killer T (NKT) cells are a unique lymphocyte population that makes important contributions to host defense against numerous microbial pathogens. The powerful immunomodulatory effects of these cells can be exploited in mice by cognate antigens for multiple therapeutic purposes, including for protection from infectious diseases and as adjuvants to improve vaccines against microbial organisms. These applications have potential to treat and prevent infectious diseases in livestock species that express NKT cells, including pigs. In this study, immune tissues from commercial swine of mixed genetic background were compared for NKT cell frequency, cytokine secretion and subset ratios. Pigs were also injected with the model antigen hen-egg lysozyme (HEL) in conjunction with one of three glycosphingolipids, alpha-galactosylceramide (αGC), OCH and C-glycoside that selectively activate NKT cells, to assess the adjuvant potential of each. There was significant variation between individual pigs for all NKT cell parameters measured. The NKT cell agonists elicited HEL-specific immune responses of different quality, but only αGC increased the systemic concentration of NKT cells. Peripheral blood NKT cell frequency measured prior to treatment was a poor predictor of how individual animals responded to NKT cell therapy. However, our results show that although NKT cells vary considerably between pigs, there exists considerable potential to harness these cells to protect swine from infectious diseases.

    isplatin (CP) is one of the most active cytotoxic agents in the treatment of cancer and has adverse side effects such as hepatotoxicity and nephrotoxicity. The aim of this study was focused on investigating the possible protective effect of royal jelly (RJ) against oxidative stress caused by CP injury of the liver and inflammatory changes in male albino rats. Twenty four albino rats were divided into four equal groups as follows: control group, cisplatin group : (rats injected i.p. with single dose from cisplatin (CP, 7 mg / kg body weight,), royal jelly RJ group : rats treated for 15 consecutive days by gavage with RJ (300 mg/kg/day/orally), royal jelly-cisplatin group, rats treated with royal jelly orally for 15 consecutive days by gavage (300 mg/kg/day) followed by a single injection i.p. from CP (7 mg / kg body weight). The obtained results revealed that the administration of royal jelly with cisplatin in rats significantly ameliorated the changes occurred in the biochemical parameters (GSH, GPx and CAT were significantly decreased in liver of cisplatin-treated rats and increasing ALT and AST). The histopathological results showed distinctive pattern of hepatotoxic changes in cisplatin group, while in the royal jelly-cisplatin group the liver tissues showed reductions lesions. In conclusion, royal jelly acts in the liver as a potent scavenger of free radicals to prevent or ameliorates the toxic effects of CP as shown by biochemical and histopathological investigations and might provide substantial protection against cisplatin-induced hepatotoxicity and inflammatory

    To systematically review and assess the efficacy and safety of hydroxychloroquine (HCQ) for treating primary Sjogren's syndrome (pSS). Five electronic databases (Pubmed, EMBASE, Web of science, Ovid, Cochrane Library) were searched for randomized controlled trials and retrospective or prospective studies published in English that reported the effect of HCQ on pSS. The subjective symptoms (sicca symptoms, fatigue and pain) and the objective indexes (erythrocyte sedimentation rate and Schirmer test) were assessed as main outcome measures. A meta-analysis and descriptive study on the efficacy and safety of HCQ were conducted. The estimate of the effect of HCQ treatment was expressed as a proportion together with 95% confidence interval, and plotted on a forest plot. Four trials with totals of 215 SS patients, including two randomized controlled trials, one double blind crossover trial and one retrospective open-label study, were analyzed in this review. For dry mouth and dry eyes, the effectiveness of HCQ treatment was essentially the same as placebo treatment. For fatigue, the effectiveness of HCQ was lower than placebo. The efficacy of HCQ in treating pain associated with pSS was superior to that of the placebo. There was no significant difference between HCQ-treated groups and controls in terms of Schirmer test results, but HCQ could reduce the erythrocyte sedimentation rate compare with placebo. A descriptive safety assessment showed that gastrointestinal adverse effects were the most common adverse effects associated with HCQ. This systematic review showed that there is no significant difference between HCQ and placebo in the treatment of dry mouth and dry eye in pSS. Well-designed, randomized, controlled trials are needed to provide higher-quality evidence to confirm our findings, and future studies should focus on some other index or extraglandular measures, such as cutaneous manifestations, to further explore the therapeutic effect of HCQ in

    In this study we test the hypothesis that nonlinear optical (NLO) multiphoton photoactivation of riboflavin using a focused femtosecond (FS) laser light can be used to induce cross-linking (CXL) and mechanically stiffen collagen as a potential clinical therapy for the treatment of keratoconus and corneal ectasia. Riboflavin-soaked, compressed collagen hydrogels are cross-linked using a FS laser tuned to 760 nm and set to either 100 mW (NLO CXL I) or 150 mW (NLO CXL II) of laser power. FS pulses are focused into the hydrogel using a 0.75 NA objective lens, and the hydrogel is three-dimensionally scanned. Measurement of hydrogel stiffness by indentation testing show that the calculated elastic modulus (E) values are significantly increased over twofold following NLO CXL I and II compared with baseline values (P0.05). This data suggests that NLO CXL has a comparable effect to conventional UVA CXL in mechanically stiffening collagen and may provide a safe and effective approach to localize CXL at different regions and depths within the cornea.

    Research into bleaching focuses on new products in order to minimize undesirable effects. This study evaluated the bleaching effectiveness of a new enzymatic-activated dentifrice. A total of 20 volunteers were bleached with a dentifrice containing 5% lactoperoxidase and 3% carbamide peroxide applied three times a day for two minutes over 21 days. Color was recorded before and after the treatment using a spectrophotometer. CIELAB differences were calculated before and after treatment using the paired t test (P whitening teeth. Enzymatic dental bleaching is able to increase the efficiency of low concentration peroxides, reducing the potential risk of peroxides on oral tissues.

    Topical corticosteroid and calcineurin inhibitor have similar therapeutic benefits in atopic dermatitis (AD), but the differences in therapeutic mechanisms of action of these agents against AD symptoms are not fully understood. This study was performed to examine the different effects of topical betamethasone valerate (BMV), clobetasol propionate (CBP), and tacrolimus (TAC) on itch-related behavior and dermatitis in NC/Nga mice with AD-like symptoms. AD-like dermatitis was induced in the dorsal skin of NC/Nga mice by repeated topical application of Dermatophagoides farinae body (Dfb) ointment twice weekly for three weeks. Mice with dermatitis scores over 5 were divided into five groups with equal dermatitis scores and treated with BMV, CBP, TAC, or Vaseline (Vas) once daily for two consecutive days, or were not treated (NT). Scratching behavior was analyzed using a SCLABA ® -Real system. Transepidermal water loss (TEWL) before and after treatment was measured using a Tewameter ® TM210. Skin collected from each group was analyzed histologically. After the second treatment, dermatitis showed significantly greater improvement in the CBP and TAC-treated groups than in the Vas-treated and NT groups. The numbers of scratching bouts were significantly lower in CBP and TAC-treated mice than in Vas-treated mice. TEWL was significantly lower in TAC-, but not in CBP-, treated mice than in Vas-treated mice. Immunohistochemical examination showed that BMV, CBP and TAC did not reduce the increased densities of epidermal protein gene product 9.5- and substance P-immunoreactive fibers. The numbers of dermal CD4-immunoreactive T cells were significantly lower in BMV and CBP-treated mice than in Vas-treated and NT mice. The numbers of dermal eosinophils were significantly lower in BMV, CBP and TAC-treated mice than in Vas-treated and NT mice, with CBP showing the strongest effect. CBP significantly reduced epidermal thickness compared with Vas and NT. There were no significant

    In a trial to improve results of therapy with 153 Sm-EDTMP for pain control in patients with disseminated bone metastases dosimetric studies were performed. Out of 30 treated patients 8 were selected for the study at random (5 breast Ca., 3 prostate Ca.). Whole body retention (WBR) of 99m Tc-DPD and 99m Tc-EDTMP was compared with WBR of 153 Sm-EDTMP. Volume of metastases and regional 99 m Tc-phosphonate uptake were assessed by SPECT and conjugated whole body scan data after phantom studies. Effective half-life was estimated also. Clinically results of pain control, side effects and changes of in vitro parameters were followed after therapy for up to 8 months. Therapy was performed in these patients with 55,5 MBq/kg body weight. Results showed an identical pattern of radioactivity distribution on 99 Tc-phosphonate and 153 Sm-EDTMP posttherapy scans, WBR of tracers and therapeutic agent was similar. Tumour volumes were 151-652 mL, count ratios metastases/normal bone 1,72-2,41, so that 6-50% of applied 153 Sm-EDTMP were concentrated in bone lesions. This gave dose estimates of 2,8-13,7 Gy in metastases. Evaluation of clinical results showed that the majority of very good results were observed in patients receiving > 10 Gy (n=3) while with lower doses only 1/4 responded very well. 1 patient was lost to follow-up due to death in the first month after therapy. Moderate and transient myelodepression (platelets) was seen in 3/7 patients without relation to Gy applied. As obviously 153 Sm concentration is not homogenous in bone metastases it can be assumed, that in border zones between tumour and bone 30-40 Gy can be delivered when 10 Gy are calculated for the whole lesion, which would explain the satisfactory therapeutic effect in our study. The dosimetric approach to 153 Sm-EDTMP therapy could necessitate the application of higher amounts of 153 Sm-EDTMP to reach adequate radiation doses in lesions without necessarily increasing risk of myelodepression and with even

    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: 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

The present study was designed to investigate the effect of human placenta mesenchymal stem cells (hPMSCs expressing green fluorescent protein (GFP on carbon tetrachloride- (CCl4- induced liver fibrosis in rats. Methods. Liver fibrosis was induced by subcutaneous injection with CCl4; hPMSCs were directly transplanted into rats through the caudal vein. The therapeutic efficacy of hPMSCs on liver fibrosis was measured by liver function tests, liver elastography, histopathology, Masson’s trichrome and Sirius red staining, and immunohistochemical studies. The expression levels of fibrotic markers, transforming growth factor β1 (TGF-β1 and α-smooth muscle actin (α-SMA, were assessed using real-time polymerase chain reaction. Results. We demonstrated that liver fibrosis was significantly dampened in the hPMSC transplantation group according to the Laennec fibrosis scoring system and histological data. The Sirius red-stained collagen area and the elastography score were significantly reduced in the hPMSC-treated group. Meanwhile, hPMSC administration significantly decreased TGF-β1 and α-SMA expression and enhanced liver functions in CCl4-induced fibrotic rats. Conclusion. This study indicates that transplantation of hPMSCs could repair liver fibrosis induced by CCl4 in rats, which may serve as a valuable therapeutic approach to treat liver diseases.

    It has been about nine decades since the proposal of Otto Warburg on the metabolism of cancer cells. Unlike normal cells which undergo glycolysis and oxidative phosphorylation in the presence of oxygen, proliferating and cancer cells exhibit an increased uptake of glucose and increased rate of glycolysis and predominantly undergo lactic acid fermentation. Whether this phenomenon is the consequence of genetic dysregulation in cancer or is the cause of cancer still remains unknown. However, there is certainly a strong link between the genetic factors, epigenetic modulation, cancer immunosurveillance and the Warburg effect, which will be discussed in this review. Dichloroacetate and 3-bromopyruvate are among the substances that have been studied as potential cancer therapies. With our expanding knowledge of cellular metabolism, therapies targeting the Warburg effect appear very promising. This review discusses different aspects of these emerging therapies.

    Whole brain exposure with supervoltage x irradiation was carried out in three sets of Macaca mulatta. Two sets of 12 monkeys each, at puberty, received single and fractionated exposures, respectively. One set of 21 monkeys in adulthood received a fractionated exposure. Exposure to 1000 rads in a single dose, at puberty, caused no late effects. Exposure to 1500 rads caused small areas of necrosis in the forebrain white matter at 26 weeks, but a much more extensive involvement at and beyond 52 weeks that included confluent areas of necrosis in gray and white matter. Brain loss resulted in ventricular dilatation. Gliomas appeared in two out of three monkeys at or beyond 52 weeks. Exposure to 2000 rads caused such a wide scatter of focal areas of necrosis, including those in the brain stem, that survival beyond 20 to 26 weeks was not possible. All showed enlarged ventricular systems. Whole brain exposure, 200 rads a day, five days a week, for a course of 4000 rads, at puberty, resulted in no delayed effects. Whole brain exposure to 6000 rads in a six weeks course, in the adult, produced less effects than the same dose at puberty. The onset of the scattered necrotic lesions was later than expected, appearing in one out of three animals at 33 weeks, two out of three animals at 52 weeks, and two out of three at 104 weeks. The lesions at 104 weeks were predominantly mineralized, but were accompanied by a greater extent of telangiectasia than seen in the pubescent monkeys

    Breviscapine is a crude extract of several flavonoids of Erigeron breviscapus (Vant.) Hand.-Mazz. , containing more than 85% of scutellarin, which has been traditionally used in China as an activating blood circulation medicine to improve cerebral blood supply. Accumulating evidence from various in vivo and in vitro studies has shown that breviscapine exerts a broad range of cardiovascular pharmacological effects, including vasodilation, protection against ischaemia/reperfusion (I/R), anti-inflammation, anticoagulation, antithrombosis, endothelial protection, myocardial protection, reduction of smooth muscle cell migration and proliferation, anticardiac remodeling, antiarrhythmia, blood lipid reduction, and improvement of erectile dysfunction. In addition, several clinical studies have reported that breviscapine could be used in conjunction with Western medicine for cardiovascular diseases (CVDs) including coronary heart disease, myocardial infarction, hypertension, atrial fibrillation, hyperlipidaemia, viral myocarditis, chronic heart failure, and pulmonary heart disease. However, the protective effects of breviscapine on CVDs based on experimental studies along with its underlying mechanisms have not been reviewed systematically. This paper reviewed the underlying pharmacological mechanisms in the cardioprotective effects of breviscapine and elucidated its clinical applications.

Although the term sarcopenia was first coined in 1989, its etiology is still poorly understood. Moreover, a consensus for defining sarcopenia continues to elude us. Sarcopenic changes in the muscle include losses in muscle fiber quantity and quality, alpha-motor neurons, protein synthesis rates, and anabolic and sex hormone production. Other factors include basal metabolic rate, increased protein dietary requirements, and chronic inflammation secondary to age-related changes in cytokines and oxidative stress. These changes lead to decreased overall physical functioning, increased frailty, falls risk, and ultimately the loss of independent living. Because the intertwining relationships of these factors are complex, effective treatment options are still under investigation. The published data on sarcopenia are vast, and this review is not intended to be exhaustive. The aim of this review is to provide an update on the current knowledge of the definition, etiology, consequences, and current clinical trials that may help address this pressing public health problem for our aging populations.Keywords: aging, muscle loss, nutrition, physical activity

    Full Text Available Rheumatoid arthritis (RA is a chronic inflammatory autoimmune disease, characterized by leukocyte infiltration, a chronic inflammation of the joint, a pannus formation and the extensive destruction of the articular cartilage and bone. Several proinflammatory cytokines such as tumor necrosis factor-α (TNF-α, interleukin-1β (IL-1β and interleukin 6 (IL-6 have been implicated in the pathological mechanisms of synovial tissue proliferation, joint destruction and programmed cell death in rheumatoid joint. In the Korean traditional medicine, Hominis placenta (HP as an herbal solution of herb-acupuncture has been widely used to treat the inflammatory diseases including RA. In order to study the medicinal effect of HP herb-acupuncture on rheumatoid joint, an adjuvant-induced arthritis (AIA was generated by the injection of 1.5 mg of Mycobacterium tuberculosis, emulsified in squalene, to the base of the tail of Spraque-Dawley (SD rats. After onset stage of polyarthritis, HP was daily injected to the Zusanli (ST36 acupuncture points in both of rat lags and the expression patterns of cytokines such as TNF-α, IL-1β, and IL-6 at the knee joint were analyzed using immunostaining and RT-PCR. The HP herb-acupuncture was found to be effective to alleviate the arthritic symptoms in adjuvant-induced arthritic rats as regards the joint appearance and the expression profiles of inflammatory cytokines. In conclusion, therapeutic effects of HP herb-acupuncture on the rat with AIA might be related to anti-inflammatory activities of the hurb-acupuncture.

    ABSTRACT Widespread antibiotic use in clinical medicine and the livestock industry has contributed to the global spread of multidrug-resistant (MDR) bacterial pathogens, including Acinetobacter baumannii. We report on a method used to produce a personalized bacteriophage-based therapeutic treatment for a 68-year-old diabetic patient with necrotizing pancreatitis complicated by an MDR A. baumannii infection. Despite multiple antibiotic courses and efforts at percutaneous drainage of a pancreatic pseudocyst, the patient deteriorated over a 4-month period. In the absence of effective antibiotics, two laboratories identified nine different bacteriophages with lytic activity for an A. baumannii isolate from the patient. Administration of these bacteriophages intravenously and percutaneously into the abscess cavities was associated with reversal of the patient's downward clinical trajectory, clearance of the A. baumannii infection, and a return to health. The outcome of this case suggests that the methods described here for the production of bacteriophage therapeutics could be applied to similar cases and that more concerted efforts to investigate the use of therapeutic bacteriophages for MDR bacterial infections are warranted.

    Full Text Available Postpartum hemorrhage is among the leading causes of maternal mortality throughout the world. Severe blood loss contributes to  the increased blood transfusion risk with its concerned inherent adverse events and therefore increased rate of emergency re-operative interventions such as arterial ligation or hysterectomy. It also can lead to protracted anemia, particularly in low or median income countries. Extended application of antifibrinolytic agents such as tranexamic acid has been customary for long years to stop or reduce blood loss in postpartum period. However, there are not enough reliable evidence to approve the real efficacy of these drugs. In this brief and summary review, we pointed to a few conducted studies. The PubMed was searched for keyword including postpartum hemorrhage, tranexamic acid, cesarean section, vaginal delivery, and blood loss prevention. The articles with language other than English were excluded from our review.  We concluded that more convincing information is needed to determine the precise effects of tranexamic acid, and its benefits against adverse effects.

  13. Oxidative Stress and Immunosenescence: Therapeutic Effects of Melatonin

    Full Text Available Age-associated deterioration in the immune system, which is referred to as immunosenescence, contributes to an increased susceptibility to infectious diseases, autoimmunity, and cancer in the elderly. A summary of major changes associated with aging in immune system is described in this paper. In general, immunosenescence is characterized by reduced levels of peripheral naïve T cells derived from thymus and the loss of immature B lineage cells in the bone marrow. As for macrophages and granulocytes, they show functional decline with advancing age as evidenced by their diminished phagocytic activity and impairment of superoxide generation. The indole melatonin is mainly secreted in the pineal gland although it has been also detected in many other tissues. As circulating melatonin decreases with age coinciding with the age-related decline of the immune system, much interest has been focused on melatonin’s immunomodulatory effect in recent years. Here, we underlie the antioxidant and immunoenhancing actions displayed by melatonin, thereby providing evidence for the potential application of this indoleamine as a “replacement therapy” to limit or reverse some of the effects of the changes that occur during immunosenescence.

    Balneotherapy has been widely used for treatment of chronic low back pain recently. However there are only a few clinical controlled trials on balneotherapy. The aim of the present study was to evaluate the effects of balneotherapy in patients with chronic low back pain. Sixty patients with lumbar spondylosis were included in the study. In Group 1, patients received both balneotherapy and physiotherapy and in Group 2, patients received only physiotherapy for three weeks. The intensity of the pain was evaluated by Visual Analog Scale (VAS) and functional disability was scored according to Revised Oswestry Index (ROI). Spinal mobility was assessed by the Schober and lateral flexion tests. Variables were evaluated before and after the three weeks of treatment. The groups were comparable regarding age (P = 0.970) and sex (P = 0.357). There was no statistically significant difference between the two groups for baseline VAS (P = 0.838), Schober test (P = 0.226), and right (P = 0.642) and left (P = 0.674) lateral flexion measurements, and ROI scores (P = 0.798). At the end of the therapy, all clinical parameters significantly improved in patients in both of the groups (P balneotherapy may be effective in the treatment of patients with chronic low back pain.

    2016-03-01

    In this article we explore the ethics of manipulating verbal information for the sake of influencing health outcomes through placebo and nocebo responses. Recent scientific research on placebo and nocebo effects has drawn attention to the ways in which communication by health professionals may modulate the symptoms of patients across an array of highly prevalent conditions such as pain, depression, anxiety, insomnia, irritable bowel syndrome, migraine, and Parkinson's disease. The positive and negative effects of clinicians' communication on patient outcomes pose important ethical issues, which we describe in this article under the label of "the ethics of therapeutic communication" (TC). We begin by reviewing available evidence supporting the claim that doctor-patient communication has therapeutic effects. We then identify in truthfulness, helpfulness, and pragmatism three morally relevant considerations that can guide clinicians in therapeutic communication with their patients. Finally, we examine the ethics of using TC to enhance the effectiveness of proven medical interventions and open-label placebos.

  16. 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.

    AIM: 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. METHODS: 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-γ (INFγ) and tumor necrosis factor-α (TNF-α) cytokine-producing cells in the gastric mucosa, and thickness of the mucus layer. RESULTS: 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 ± 0.03 vs 2.0 ± 0.6, P < 0.05). A marked decrease in INFγ+ (15 ± 1.0 vs 28 ± 1.2, P < 0.05) and TNF-α+ (16 ± 3.0 vs 33 ± 3.0, P < 0.05) cells and an increase in IL-10+ (28 ± 1.5 vs 14 ± 1.3, P < 0.05) cells compared to the gastritis group, was observed. Also, an increase in the thickness of the mucus gel layer (2.2 ± 0.6 vs 1.0 ± 0.3; 5.1 ± 0.8 vs 1.5 ± 0.4 in the corpus and antrum mucosa, respectively, P < 0.05) compared with the gastritis group was noted. A milk suspension of the purified EPS from S. thermophilus CRL1190 was also effective as therapy for gastritis. CONCLUSION: 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.

    Since the early 1980s, there has been considerable attention in the psychology literature to mental health problems related to living in a world threatened by nuclear destruction. Questionnaires were mailed to 630 psychotherapists from the Colorado Psychological Association, California Psychotherapists for Social Responsibility, California Psychologists for Social Responsibility, the US Army, and the APA Division of Military Psychology; 174 questionnaires were returned. It was hypothesized that liberalism, nuclear weapons opposition, nuclear concern, nuclear awareness, and anti-nuclear activism in psychotherapists would facilitate perception of, and openness to working with, a client's nuclear concerns and thus, would be positively correlated with intentions to discuss nuclear issues with clients in three different clinical vignettes. Results indicated that when controlling for subject group, psychotherapy orientation, age, sex, and income, all five independent variables were positively correlated with responses to all three clinical vignettes, with nuclear concern having the strongest unique effect in accounting for variance in responses to the vignettes

    Purpose: To determine whether radiation therapy delivered to the paranasal sinuses causes any long-term impairment in neurocognitive function as a result of incidental brain irradiation. Methods and Materials: Nineteen patients who received paranasal sinus irradiation at least 20 months and up to 20 years before assessment were given a battery of neuropsychologic tests of cognitive function. Radiation was delivered by a three-field (one anteroposterior and two lateral) technique. The median radiation dose was 60 Gy (range 50-68 Gy) in fractions of 1.8 to 2 Gy. The volume of irradiated brain was calculated from planning computed tomography slices or simulation films. The results of the neuropsychologic tests were compared to normative control values. Results: Memory impairment was found in 80% of the patients, and one-third manifested difficulty with visual-motor speed, frontal lobe executive functions, and fine motor coordination. Two of the patients had frank brain necrosis with resultant dementia and blindness, and three had evidence of brain atrophy. Three of the fourteen patients without documented cerebral atrophy or necrosis were disabled from their normal activities. Three patients also developed pituitary dysfunction. Neurocognitive symptoms were related to the total dose of radiation delivered but not to the volume of brain irradiated, side of radiation boost, or chemotherapy treatment. The pattern of test findings was consistent with radiation injury to subcortical white matter. Conclusions: Radiation therapy for paranasal sinus cancer may cause delayed neurocognitive side effects. Currently, however, the development of severe adverse effects appears to be decreasing because of improvements in the techniques used to deliver radiation. Lowering the total dose and improving dose distributions should further decrease the incidence of delayed brain injury due to radiation

    To investigate, both objectively and subjectively, the effect of music on children in a pediatric cardiac intensive care unit following heart surgery, in conjunction with standard care. Randomized clinical trial with placebo, assessing 84 children, aged 1 day to 16 years, during the first 24 hours of the postoperative period, given a 30 minute music therapy session with classical music and observed at the start and end of the session, recording heart rate, blood pressure, mean blood pressure, respiratory rate, temperature and oxygen saturation, plus a facial pain score. Statistical significance was set at 5%. Five of the initial 84 patients (5.9%) refused to participate. The most common type of heart disease was acyanotic congenital with left-right shunt (41% of cases: 44.4% of controls). Statistically significant differences were observed between the two groups after the intervention in the subjective facial pain scale and the objective parameters heart rate and respiratory rate (p music was observed with children during the postoperative period of heart surgery, by means of certain vital signs (heart rate and respiratory rate) and in reduced pain (facial pain scale). Nevertheless, there are gaps to be filled in this area, and studies in greater depth are needed.

    Full Text Available Systemic lupus erythematosus (SLE is a chronic autoimmune disease that leads to severe multiorgan damage. Lang Chuang Fang (LCF is a Chinese herbal medicine that is clinically prescribed for treating SLE. In this study, we examined the therapeutic effects of LCF granule on lupus-prone MRL/lpr mice. Female mice were randomly separated into six groups, and LCF treatment groups received LCF granule at the dosage of 0.97 g/kg/d, 1.95 g/kg/d, and 3.90 g/kg/d, respectively. Here, we found that, compared to the MRL/lpr mice, both the spleen coefficient and thymus coefficient were reduced in the LCF granule-treated mice. There was a marked downregulation in CRP and anti-dsDNA autoantibody and an evident upregulation of CH50 in LCF granule-treated mice. LCF granule treatment also obviously reduced the proteinuria, BUN, and SCr levels in MRL/lpr mice at the dosage of 0.97 g/kg/d, 1.95 g/kg/d, and 3.90 g/kg/d, indicating that LCF granule alleviated the renal injury of MRL/lpr mice. Furthermore, LCF granule decreased p65 NF-κB levels and increased Sirt1 and Nrf2 levels in the kidney tissues of MRL/lpr mice, which might elucidate the beneficial effects of LCF on lupus nephritis. In conclusion, this study demonstrates that LCF granule has therapeutic effects on lupus-prone MRL/lpr mice.

    Cranial osteopathic manipulative medicine (OMM) involves the manipulation of the primary respiratory mechanism to improve structure and function in children and adults. To identify and critically evaluate the literature regarding the clinical efficacy of cranial OMM. The clinical keywords "cranial manipulation" OR "osteopathy in the cranial field" OR "cranial osteopathy" OR "craniosacral technique" were searched in the following electronic databases: EMBASE, MEDLINE In-Process & Other Non-Indexed Citations, The Cochrane Central Register of Controlled Trials, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and AMED (Alternative Medicine). Searches were conducted in April 2011 with no date restriction for when the studies were completed. Randomized controlled trials and observational studies that measured the effectiveness of cranial OMM on humans were included in the study. Exclusion criteria included non-English language articles, studies not relevant to cranial OMM, animal studies, and studies in which there was no clear indication of the use of cranial OMM. Studies that described the use of cranial OMM with other treatment modalities and that did not perform subgroup analysis were also excluded. The present study did not have criteria regarding type of disease. Outcome measures on pain, sleep, quality of life, motor function, and autonomic nervous system function were extracted. The methodological quality of the trials was assessed using the Downs and Black checklist. Of the 8 studies that met the inclusion criteria, 7 were randomized controlled trials and 1 was an observational study. A range of cranial OMM techniques used for the management of a variety of conditions were identified in the included studies. Positive clinical outcomes were reported for pain reduction, change in autonomic nervous system function, and improvement of sleeping patterns. Methodological Downs and Black quality scores ranged from 14 to 23 points out of a maximum of

    Benign prostatic hyperplasia (BPH) is one of the major disorders of the urinary system in elderly men. Docosahexaenoic acid (DHA) is the main component of n-3 polyunsaturated fatty acids (n-3 PUFAs) and has nerve protective, anti-inflammatory and tumour-growth inhibitory effects. Here, the therapeutic potential of DHA in treating BPH was investigated. Seal oil effectively prevented the development of prostatic hyperplasia induced by oestradiol/testosterone in a rat model by suppressing the increase of the prostatic index (PI), reducing the thickness of the peri-glandular smooth muscle layer, inhibiting the proliferation of both prostate epithelial and stromal cells, and downregulating the expression of androgen receptor (AR) and oestrogen receptor α (ERα). An in vitro study showed that DHA inhibited the growth of the human prostate stromal cell line WPMY-1 and the epithelial cell line RWPE-1 in a dose- and time-dependent manner. In both cell lines, the DHA arrested the cell cycle in the G2/M phase. In addition, DHA also reduced the expression of ERα and AR in the WPMY-1 and RWPE-1 cells. These results indicate that DHA inhibits the multiplication of prostate stromal and epithelial cells through a mechanism that may involve cell cycle arrest and the downregulation of ERα and AR expression. - Highlights: • Seal oil prevents oestradiol/testosterone (E2/T)-induced BPH in castrated rats. • Seal oil downregulates the expression of oestrogen receptor α(ERα) and androgen receptor (AR) in rat BPH tissues. • DHA inhibits the growth of human prostate stromal and epithelial cells in vitro. • DHA arrests human prostate stromal and epithelial cells in the G2/M phase and downregulates the expression of cyclin B1. • DHA inhibits the expression of ERα and AR in human prostate stromal and epithelial cells.

    Mild therapeutic hypothermia (MTH) is being used to improve neurological outcome and survival in patients successfully resuscitated after cardiac arrest. The impact on coagulation may be difficult to assess since most coagulation parameters are measured at 37°C and not at actual body core temperature. Therefore we investigated the effects of MTH both at body core (target) temperature of 32°C and at 37°C. Patients admitted at the ICU after cardiac arrest treated with MTH. Baseline blood samples, measured at 37°C were taken directly at arrival. The second and third samples were drawn within 1h and 24h after reaching target temperature and were measured at 32°C and 37°C. A final sample was drawn when the patient returned to normotemperature (measured at 37°C). Clotting time (CT) and maximum clotting formation (MCF) were measured with thromboelastometry. Upon reaching target temperature (32°C) Extem and Intem CT were increased compared to baseline with 57s (49-75) to 65s (59-72) and 165s (144-183) to 193s (167-212) respectively (median with IQR; P<0.05), with a further significant increase after 24h of hypothermia with 68s (57-80) and 221s (196-266). Samples analyzed at 32°C showed a significant longer CT of 12s in Extem and 33s in Intem compared to 37°C. MCF was not affected by MTH or adjustment of temperature. The mild effect of MTH on coagulation parameters remains unidentified when measured at 37°C. Although measurements at 32°C differ from those at 37°C, this does not appear to be of clinical relevance as all values were still within the reference range. Copyright © 2014 Elsevier Ireland Ltd.

    Chagas disease cardiomyopathy is a parasite-driven inflammatory disease to which there are no effective treatments. Here we evaluated the therapeutic potential of N,N-dimethylsphingosine(DMS), which blocks the production of sphingosine-1-phosphate(S1P), a mediator of cellular events during inflammatory responses, in a model of chronic Chagas disease cardiomyopathy. DMS-treated, Trypanosoma cruzi-infected mice had a marked reduction of cardiac inflammation, fibrosis and galectin-3 expression when compared to controls. Serum concentrations of galectin-3, IFNγ and TNFα, as well as cardiac gene expression of inflammatory mediators were reduced after DMS treatment. The gene expression of M1 marker, iNOS, was decreased, while the M2 marker, arginase1, was increased. DMS-treated mice showed an improvement in exercise capacity. Moreover, DMS caused a reduction in parasite load in vivo. DMS inhibited the activation of lymphocytes, and reduced cytokines and NO production in activated macrophage cultures in vitro, while increasing IL-1β production. Analysis by qRT-PCR array showed that DMS treatment modulated inflammasome activation induced by T. cruzi on macrophages. Altogether, our results demonstrate that DMS, through anti-parasitic and immunomodulatory actions, can be beneficial in the treatment of chronic phase of T. cruzi infection and suggest that S1P-activated processes as possible therapeutic targets for the treatment of Chagas disease cardiomyopathy.

    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.

    To compare contrast-enhanced color Doppler ultrasound (CECDUS) with spiral CT in the evaluation of the therapeutic efficacy of malignant hepatic tumors after radio-frequency ablation (RFA). During a recent 2 year period (April 1999 to March 2001). One hundred fifteen hepatic tumors (95 hepatocellular carcinomas and 20 metastases; mean diameter, 2.7 cm) from 83 consecutive patients (60 men and 23 women; mean age, 57 years) that were treated with RFA were included in this study. Both CECDUS and two-or three phase spiral CT were performed a day after RFA as the immediate follow-up study in most cases. Afterward, both imaging studies were alternatively performed on monthly basis, but when incomplete ablation was suspected on one follow-up imaging study, the other imaging study was performed within a week for comparison. For ultrasound contrast agent, a suspension of 2.5 g or 4.0 g Levovist (Schering AG, Berlin, Germany) with a concentration of 300 mg/mL was used. For evaluating the therapeutic efficacy, the presence of viable portion, either residual or recurrent, within the ablated tumor was determined on each imaging study. The criteria for viable portion were defined as focal or irregular enhancement at the periphery of the ablated tumor on the arterial or portal phase spiral CT images and intratumoral vascularities on CECDUS. The correspondence rate between both imaging studies was assessed to compare the diagnostic accuracy of both studies in evaluating a residual or recurrent tumor. In addition, their imaging findings were analyzed. Analyzing both imaging findings of 116 malignant hepatic tumors, the correspondence rate between CECDUS and CT obtained after 116 times of imaging studies was 91.4% (106/116). For the diagnosis of residual or recurrent tumors, the sensitivity, specificity and diagnostic accuracy of spiral CT were 71%, 99%, and 94%, respectively, while those of CECDUS were 87%, 99%, and 97%, respectively. As the immediate follow-up study, CECDUS seemed

    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

    The Testis is considered as one of the most sensitive organs in the body to ionizing radiation because of the rapidly dividing germinal epithelium. Seminal oxidative stress (OS) causes damage of the sperm plasma membrane and loss of its DNA integrity, therefore, the need for an effective therapeutic agent is evident. The present study investigated the mechanism(s) of potential therapeutic effect of ferulic acid (FA) on radiation-induced testicular damage. Mature male albino rats were either exposed to single dose γ-radiation (5Gy) and/ or treated with FA (50 mg/ kg body wt, orally), daily for seven days post-irradiation. FA significantly reversed OS effects of γ-rays that was evidenced by increasing malondialdehyde (MDA) and decreasing ferric reducing antioxidant power (FRAP) and catalase (CAT) activity. In addition, alterations in some trace elements such as zinc (Zn), cupper (Cu), iron (Fe) and manganese (Mn) were observed. Furthermore, sperm head abnormalities noticeably increased in the γ-irradiated group; in contrast, FA treatment ameliorated these alterations. In conclusion, FA exhibited curative effect against radiation induced testicular damage.

    The purpose of this qualitative study was to describe how individuals who self-report therapeutic use of cannabis perceive its health effects. Data from 23 individual interviews were transcribed and analyzed. Understandings of gendered roles and identities were used to explore the data and interpret differences in perceptions. Descriptions of the health benefits of cannabis for therapeutic purposes included cannabis as life preserving, a disease therapy, a medicine for the mind, a means for self-management, and a way to manage addiction. Self-management of risks focused on the potential effects of excessive use, smoking-related risks, and purchasing precautions. Although the reports of women and men were similar in many respects, there were important differences in patterns and practices of use that reflected gender influences. Insights from the study provide direction for developing gender-specific information to support decision making and usage for therapeutic users.

    In general, treatment of childhood obesity focuses on treating the obese children. The results of child-directed treatments are disappointing in the long run. In the current study, it is tested whether a treatment aimed solely at obese children's parents results in positive effects on the children's weight status. In addition, potential predictors of treatment success are identified. The parents of 98 overweight or obese children (aged 7-13 years) were randomly assigned to either the cognitive-behavioural group treatment (eight sessions) or the waiting-list control group. With respect to child body mass index (BMI) percentile, the parents' treatment was successful in reducing overweight from pretreatment to posttreatment: BMI percentile decreased significantly by 2.4% in the treatment group, whereas there was no change in the waiting-list control group. There was no significant relapse at follow-up (3 months). Child BMI percentile did not decrease in the waiting-list control group. In addition, significant main effects of time were found for both groups with respect to eating psychopathology (decrease), self-esteem (increase) and negative thoughts (decrease). Finally, parental BMI decreased significantly only in the treatment group. Four predictors were identified with respect to treatment success, namely, lower socioeconomic status, younger age of the child, higher parental attendance and lower BMI percentile of the child before treatment. The parents' treatment had significant effects on child and parent BMI. Long-term endurance of these positive effects needs to be studied. Striking are the positive effects of time in the waiting-list control group for some psychological outcome measures. Obviously, waiting for treatment already affects psychological processes (but not behaviour) in the children.

    Metronidazole (MTZ) is used as an antiparasitic drug. Curcumin is considered as anti-oxidant and anti-inflammatory agent. The ameliorative effects of curcumin on MTZ induced toxicity on mice spermatozoon tail length, count, motility and testosterone level were investigated. MTZ was administered in 500 and 165 (high and therapeutic doses) mg/kg/day, with and without curcumin (100 mg/kg/day). After 16 days the above parameters were assessed. Spermatozoon count and motility and serum testosterone level MTZ-treated (500 and 165) mice were reduced. In the mice treated with MTZ+curcumin these parameters decreased but in a lesser extent than the MTZ-treated animals. Mid-piece and total lengths of the spermatozoon tail in control animals were 31.6 ± 9.0 μm and 100.3 ± 15.0 μm and in the mice treated with high doses (500) of MTZ were reduced. The mid-piece and total spermatozoon tail length has been decreased in a lesser extent in the mice treated with high dose MTZ+curcumin than the mice treated with high dose MTZ (pspermatozoon, testosterone level and tail length in MTZ-treated mice.

    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 objective of this study was to evaluate the effect of different chemical pre-treatments on the bond durability to dental zirconia. Fully sintered IPS e.max ZirCAD (Ivoclar Vivadent) blocks were subjected to tribochemical silica sandblasting (CoJet, 3M ESPE). The zirconia samples were additionally pre-treated using one of four zirconia primers/adhesives (Clearfil Ceramic Primer, Kuraray Noritake; Monobond Plus, Ivoclar Vivadent; Scotchbond Universal, 3M ESPE; Z-PRIME Plus, Bisco). Finally, two identically pre-treated zirconia blocks were bonded together using composite cement (RelyX Ultimate, 3M ESPE). The specimens were trimmed at the interface to a cylindrical hourglass and stored in distilled water (7 days, 37 °C), after which they were randomly tested as is or subjected to mechanical ageing involving cyclic tensile stress (10 N, 10 Hz, 10,000 cycles). Subsequently, the micro-tensile bond strength was determined, and SEM fractographic analysis performed. Weibull analysis revealed the highest Weibull scale and shape parameters for the 'Clearfil Ceramic Primer/mechanical ageing' combination. Chemical pre-treatment of CoJet (3M ESPE) sandblasted zirconia using Clearfil Ceramic Primer (Kuraray Noritake) and Monobond Plus (Ivoclar Vivadent) revealed a significantly higher bond strength than when Scotchbond Universal (3M ESPE) and Z-PRIME Plus (Bisco) were used. After ageing, Clearfil Ceramic Primer (Kuraray Noritake) revealed the most stable bond durability. Combined mechanical/chemical pre-treatment, the latter with either Clearfil Ceramic Primer (Kuraray Noritake) or Monobond Plus (Ivoclar Vivadent), resulted in the most durable bond to zirconia. As a standard procedure to durably bond zirconia to tooth tissue, the application of a combined 10-methacryloyloxydecyl dihydrogen phosphate/silane ceramic primer to zirconia is clinically highly recommended.

    As the number of younger women with endometrial carcinoma has increased, fertility-sparing treatments have received more attention. Although there have been several reports on conservative treatments with progestins for endometrial carcinoma, only medroxyprogesterone acetate (MPA) is available in Japan. Dienogest has been developed as a fourth-generation progestin for treating endometriosis. Because of its high progesterone activity, its antitumor activity has attracted attention. In this study, we investigated the anticancer effect of dienogest on endometrial neoplasms using mouse model of endometrial carcinoma. Pten(loxP/loxP) mice were injected with MPA or dienogest subcutaneously to evaluate the anticancer effect against endometrial neoplasms that developed in the mice. One week after injections, histopathological analyzes were performed. Endometrial neoplasms were found in one of the eight (12.5%) mice from each group treated with either dienogest or MPA. In contrast, they were found in seven of eight (87.5%) mice not treated with progestins. Each progestin treatment showed anticancer activity against endometrial neoplasms that developed in the mice compared to those without treatment. Dienogest and MPA showed potent anticancer activity against endometrial neoplasms in our mouse model. The present study demonstrated that dienogest might be a useful therapeutic agent for human endometrial neoplasms.

    The present study aimed to investigate the protective and therapeutic effects of caffeine on rotenone-induced rat model of Parkinson's disease (PD). Rats were divided into control, PD model induced by rotenone (1.5 mg/kg intraperitoneally (i.p.) for 45 days), protected group injected with caffeine (30 mg/kg, i.p.) and rotenone for 45 days (during the development of PD model), and treated group injected with caffeine (30 mg/kg, i.p.) for 45 days after induction of PD model. The data revealed a state of oxidative and nitrosative stress in the midbrain and the striatum of animal model of PD as indicated from the increased lipid peroxidation and nitric oxide levels and the decreased reduced glutathione level and activities of glutathione-S-transferase and superoxide dismutase. Rotenone induced a decrease in acetylcholinesterase and Na + /K + -ATPase activities and an increase in tumor necrosis factor-α level in the midbrain and the striatum. Protection and treatment with caffeine ameliorated the oxidative stress and the changes in acetylcholinesterase and Na + /K + -ATPase activities induced by rotenone in the midbrain and the striatum. This was associated with improvement in the histopathological changes induced in the two areas of PD model. Caffeine protection and treatment restored the depletion of midbrain and striatal dopamine induced by rotenone and prevented decline in motor activities (assessed by open field test) and muscular strength (assessed by traction and hanging tests) and improved norepinephrine level in the two areas. The present study showed that caffeine offered a significant neuroprotection and treatment against neurochemical, histopathological, and behavioral changes in a rotenone-induced rat model of PD.

    Midodrine hydrochloride is used clinically to treat children with postural tachycardia syndrome (POTS), but it is not effective in all patients. This study was designed to explore the changes in plasma copeptin and its predictive value in assessing the therapeutic efficacy of midodrine hydrochloride in children with POTS. The study included 33 children with POTS and 26 healthy children. The group with POTS received midodrine hydrochloride treatment for 1.5-3 months. The plasma copeptin was measured using a sandwich immunoluminometric assay. A receiver operating characteristic curve was used to explore the predictive value of plasma copeptin. The plasma copeptin in the group with POTS was significantly higher than that of the control group (10.827±2.459 pmol/L vs 8.845±1.471 pmol/L, Pmidodrine hydrochloride was significantly higher than that of nonresponders (12.082±1.998 pmol/L vs 9.646±2.301 pmol/L, P=.003). Receiver operating characteristic analysis on the predictive value of plasma copeptin showed that the area under the curve was 0.800 with a 95% CI of 0.640-0.959. Using a plasma copeptin level of 10.482 pmol/L as the cutoff point produced both favorite sensitivity (81.3%) and specificity (76.5%) in predicting the efficacy of midodrine hydrochloride therapy in children with POTS. Plasma copeptin may be considered as a predictive biomarker for the likelihood of successful treatment of children with POTS with midodrine hydrochloride. Copyright © 2014 Elsevier Inc.

    There are no approved therapeutics for the treatment of dengue disease despite the global prevalence of dengue virus (DENV) and its mosquito vectors. DENV infections can lead to vascular complications, hemorrhage, and shock due to the ability of DENV to infect a variety of immune and nonimmune cell populations. Increasingly, studies have implicated the host response as a major contributor to severe disease. Inflammatory products of various cell types, including responding T cells, mast cells (MCs), and infected monocytes, can contribute to immune pathology. In this study, we show that the host response to DENV infection in immunocompetent mice recapitulates transcriptional changes that have been described in human studies. We found that DENV infection strongly induced metabolic dysregulation, complement signaling, and inflammation. DENV also affected the immune cell content of the spleen and liver, enhancing NK, NKT, and CD8 + T cell activation. The MC-stabilizing drug ketotifen reversed many of these responses without suppressing memory T cell formation and induced additional changes in the transcriptome and immune cell composition of the spleen, consistent with reduced inflammation. This study provides a global transcriptional map of immune activation in DENV target organs of an immunocompetent host and supports the further development of targeted immunomodulatory strategies to treat DENV disease. IMPORTANCE Dengue virus (DENV), which causes febrile illness, is transmitted by mosquito vectors throughout tropical and subtropical regions of the world. Symptoms of DENV infection involve damage to blood vessels and, in rare cases, hemorrhage and shock. Currently, there are no targeted therapies to treat DENV infection, but it is thought that drugs that target the host immune response may be effective in limiting symptoms that result from excessive inflammation. In this study, we measured the host transcriptional response to infection in multiple DENV target organs

    Full Text Available More than thirty years have passed since human T-cell leukemia virus type 1 (HTLV-1 was described as the first retrovirus to be the causative agent of a human cancer, adult T-cell leukemia (ATL, but the precise mechanism behind HTLV-1 pathogenesis still remains elusive. For more than two decades, the transforming ability of HTLV-1 has been exclusively associated to the viral transactivator Tax. Thirteen year ago, we first reported that the minus strand of HTLV-1 encoded for a basic Zip factor factor (HBZ, and since then several teams have underscored the importance of this antisense viral protein for the maintenance of a chronic infection and the proliferation of infected cells. More recently, we as well as others have demonstrated that HBZ has the potential to transform cells both in vitro and in vivo. In this review, we focus on the latest progress in our understanding of HBZ functions in chronicity and cellular transformation. We will discuss the involvement of this paradigm shift of HTLV-1 research on new therapeutic approaches to treat HTLV-1-related human diseases.

    Thrombotic thrombocytopenic purpura (TTP) is a rare but serious disease caused by autoantibody-mediated deficiency in von Willebrand factor (VWF) cleaving protease, ADAMTS-13. The primary acute treatment is therapeutic plasma exchange (TPE). However, some patients can develop allergic/anaphylactic reactions to the replacement (i.e., donor) plasma over time. Two potential treatment strategies for patients with TTP who demonstrate severe allergic reactions to plasma used for exchange were examined. Two patients with TTP exacerbations who developed severe allergic reactions to donor plasma were identified. One patient's TPE was re-initiated with Octaplas, a lot-batched solvent and detergent treated, type-specific, pooled donor plasma product. The other patient was exchanged with primarily albumin, followed by slow incremental exposures to donor plasma to mitigate exposures and allergic risks. Both patients were assessed for anaphylaxis. Both treatment strategies were successful in preventing any further clinically significant allergic/anaphylactic reactions and facilitated both patients' TTP remissions. Based on our experience with two similar patients with TTP exacerbations and history of anaphylactic reactions to plasma during TPE, we have identified two possible treatment protocols to achieve remission in this clinical dilemma. Substituting Octaplas for standard plasma or, alternatively, using albumin with slowly increasing amounts of standard plasma may help to mitigate the risk of further anaphylactic adverse events. J.

    Niklas Hartung

    Full Text Available Evolution of metastatic melanoma (MM under B-RAF inhibitors (BRAFi is unpredictable, but anticipation is crucial for therapeutic decision. Kinetics changes in metastatic growth are driven by molecular and immune events, and thus we hypothesized that they convey relevant information for decision making.We used a retrospective cohort of 37 MM patients treated by BRAFi only with at least 2 close CT-scans available before BRAFi, as a model to study kinetics of metastatic growth before, under and after BRAFi. All metastases (mets were individually measured at each CT-scan. From these measurements, different measures of growth kinetics of each met and total tumor volume were computed at different time points. A historical cohort permitted to build a reference model for the expected spontaneous disease kinetics without BRAFi. All variables were included in Cox and multistate regression models for survival, to select best candidates for predicting overall survival.Before starting BRAFi, fast kinetics and moreover a wide range of kinetics (fast and slow growing mets in a same patient were pejorative markers. At the first assessment after BRAFi introduction, high heterogeneity of kinetics predicted short survival, and added independent information over RECIST progression in multivariate analysis. Metastatic growth rates after BRAFi discontinuation was usually not faster than before BRAFi introduction, but they were often more heterogeneous than before.Monitoring kinetics of different mets before and under BRAFi by repeated CT-scan provides information for predictive mathematical modelling. Disease kinetics deserves more interest.

    The human retina is constantly affected by light of varying intensity, this being especially true for photoreceptor cells and retinal pigment epithelium. Traditionally, photoinduced damages of the retina are induced by visible light of high intensity in albino rats using the LIRD (light-induced retinal degeneration) model. This model allows study of pathological processes in the retina and the search for retinoprotectors preventing retinal photodamage. In addition, the etiology and mechanisms of retina damage in the LIRD model have much in common with the mechanisms of the development of age-related retinal disorders, in particular, with age-related macular degeneration (AMD). We have studied preventive and therapeutic effects of Visomitin eye drops (based on the mitochondria-targeted antioxidant SkQ1) on albino rat retinas damaged by bright light. In the first series of experiments, rats receiving Visomitin for two weeks prior to illumination demonstrated significantly less expressed atrophic and degenerative changes in the retina compared to animals receiving similar drops with no SkQ1. In the second series, the illuminated rats were treated for two weeks with Visomitin or similar drops without SkQ1. The damaged retinas of the experimental animals were repaired much more effectively than those of the control animals. Therefore, we conclude that Visomitin SkQ1-containing eye drops have pronounced preventive and therapeutic effects on the photodamaged retina and might be recommended as a photoprotector and a pharmaceutical preparation for the treatment of AMD in combination with conventional medicines.

    Therapy by low-level laser (LLL) or ultrasound (US) are commonly used as treatment after nerve crush. The aim of this study was to determine the effectiveness of such treatments to repair the neuronal cytoskeleton evaluating the variation in the number of neurofilaments. For this an experimental design was performed, which involved 30 rats divided into 6 groups: 1 - control healthy; 2 - control injured; 3 - irradiated by LLL 2 J/cm2; 4 - irradiated by LLL 10 J/cm2; 5 - irradiated by US 0.5 W/cm2 and 6 - irradiated by US 1W/cm2. With the exception of group 1 all specimens were anesthetized and underwent right sciatic nerve compression using 40N pressure for 45 seconds. Twenty-four hours after compression irradiation was started by LLL and US according protocol. In our research we found that the increase in the number of neurofilaments was related to the applied dose of LLL and US. The average value of neurofilaments / 0.25 mm2 obtained in each group was: 1 - 128; 2-100; 3-156; 4-140; 5-100; 6-148. We concluded that the application of LLL and therapeutic US increases the number of neurofilaments in rat sciatic nerve undergoing neuropraxia, with LLL being more effective compared to the US. Furthermore we concluded that the effectiveness of therapies to induce regeneration of injured nerve is related to the type of protocol used, demonstrating the need to establish an adequate radiation dose with the purpose of obtaining the best therapeutic response, thus achieving successful treatment [es

    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)

    2012-02-01

    Pulsed electromagnetic fields (PEMF) delivered by whole-body mats are promoted in many countries for a wide range of therapeutic applications and for enhanced well-being. However, neither the therapeutic efficacy nor the potential health hazards caused by these mats have been systematically evaluated. We conducted a systematic review of trials investigating the therapeutic effects of low-frequency PEMF devices. We were interested in all health outcomes addressed so far in randomized, sham-controlled, double-blind trials. In total, 11 trials were identified. They were focused on osteoarthritis of the knee (3 trials) or the cervical spine (1), fibromyalgia (1), pain perception (2), skin ulcer healing (1), multiple sclerosis-related fatigue (2), or heart rate variability and well-being (1). The sample sizes of the trials ranged from 12 to 71 individuals. The observation period lasted 12 weeks at maximum, and the applied magnetic flux densities ranged from 3.4 to 200 µT. In some trials sporadic positive effects on health were observed. However, independent confirmation of such singular findings was lacking. We conclude that the scientific evidence for therapeutic effects of whole-body PEMF devices is insufficient. Acute adverse effects have not been reported. However, adverse effects occurring after long-term application have not been studied so far. In summary, the therapeutic use of low-frequency whole-body PEMF devices cannot be recommended without more scientific evidence from high-quality, double-blind trials.

    Full Text Available Macrolides are the first-line treatment against bovine respiratory disease, and are also used to treat infections in humans. The macrolide, tylosin phosphate, is often included in the diet of cattle as a preventative for liver abscesses in many regions of the world outside of Europe. This study investigated the effects of administering macrolides to beef cattle either systemically through a single subcutaneous injection (therapeutic or continuously in-feed (subtherapeutic, on the prevalence and antimicrobial resistance of Mannheimia haemolytica and Enterococcus spp. isolated from the nasopharynx and faeces, respectively. Nasopharyngeal and faecal samples were collected weekly over 28 days from untreated beef steers and from steers injected once with tilmicosin or tulathromycin or continuously fed tylosin phosphate at dosages recommended by manufacturers. Tilmicosin and tulathromycin were effective in lowering (P < 0.05 the prevalence of M. haemolytica, whereas subtherpeutic tylosin had no effect. M. haemolytica isolated from control- and macrolide-treated animals were susceptible to macrolides as well as to other antibiotics. Major bacteria co-isolated with M. haemolytica included Pasteurella multocida, Staphylococcus spp., Acinetobacter spp., E. coli and Bacillus spp. With the exception of M. haemolytica and P. multocida, erythromycin resistance was frequently found in other isolated species. Both methods of macrolide administration increased (P < 0.05 the levels erythromycin-resistance enterococci in faeces. Development of resistance to injectable macrolides in bacteria isolated from the nasopharynx was species dependent. Therapeutic administration of tilmicosin and tularthromycin selected for macrolide resistant bacteria within both the respiratory and intestinal tract, whereas suptherapeutic administration of tylosin only selected for macrolide resistance in enteric bacteria.

    Compared with conventional chemotherapy, encapsulation of drugs in nanoparticles can improve efficacy and reduce toxicity. However, delivery of nanoparticles is often insufficient and heterogeneous because of various biological barriers and uneven tumor perfusion. We investigated a unique multifunctional drug delivery system consisting of microbubbles stabilized by polymeric nanoparticles (NPMBs), enabling ultrasound-mediated drug delivery. The aim was to examine mechanisms of ultrasound-mediated delivery and to determine if increased tumor uptake had a therapeutic benefit. Cellular uptake and toxicity, circulation and biodistribution were characterized. After intravenous injection of NPMBs into mice, tumors were treated with ultrasound of various pressures and pulse lengths, and distribution of nanoparticles was imaged on tumor sections. No effects of low pressures were observed, whereas complete bubble destruction at higher pressures improved tumor uptake 2.3 times, without tissue damage. An enhanced therapeutic effect was illustrated in a promising proof-of-concept study, in which all tumors exhibited regression into complete remission. Copyright © 2017 The Authors.

    Shoulder pain is the third leading musculoskeletal complaint seen by general practitioners. Physical therapy is often the first line of intervention in this population; however, there is limited description of what constitutes effective physical therapy treatment. No study has examined the effectiveness of therapeutic exercise across all painful shoulder conditions. Our purpose was to examine the effectiveness of therapeutic exercise as an intervention across all pathoanatomic mechanisms of shoulder pain in terms of range of motion (ROM), pain, and function. Medline via Ovid, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and the Cochrane Central Register of Controlled Trials were searched from 1997 through March 2011. Randomized controlled trials comparing physical therapist-prescribed exercises against any other type of intervention were included. Articles were qualitatively evaluated by use of the Physiotherapy Evidence Database scale by 5 separate reviewers. Data from included studies were extracted and synthesized with respect to the primary outcomes of ROM, pain, and function. Individual effect sizes were calculated with a standard formula, and overall effect was calculated by use of random- and fixed-effects models. We qualitatively reviewed 19 articles; 17 achieved the criterion of 6 or better on the Physiotherapy Evidence Database scale. Significant heterogeneity in reporting among included studies limited quantitative assessment. Overall, therapeutic exercise has a positive effect on pain and function above all other interventions. The findings for ROM were inconclusive. Therapeutic exercise is an effective intervention for the treatment of painful shoulder conditions; however, subsequent research is necessary for translation into clinical practice.

    The growing recognition of the burden of neurologic disease associated with HIV infection in the last decade has led to renewed efforts to characterize the pathophysiology of the virus within the central nervous system (CNS). The concept of the AIDS-dementia complex is now better understood as a spectrum of HIV-associated neurocognitive disorders (HAND), which range from asymptomatic disease to severe impairment. Recent work has shown that even optimally treated patients can experience not only persistent HAND, but also the development of new neurologic abnormalities despite viral suppression. This has thrown into question what the impact of antiretroviral therapy has been on the incidence and prevalence of neurocognitive dysfunction. In this context, the last few years have seen a concentrated effort to identify the effects that antiretroviral therapy has on the neurologic manifestations of HIV and to develop therapeutic modalities that might specifically alter the trajectory of HIV within the CNS.

    Evidence-based integrative medicine therapies have been introduced to promote wellness and offset side-effects from cancer treatment. Energy medicine is an integrative medicine technique using the human biofield to promote well-being. The biofield therapy chosen for study was Therapeutic Touch (TT). Breast cancer tumors were initiated in mice by injection of metastatic 66cl4 mammary carcinoma cells. The control group received only vehicle. TT or mock treatments were performed twice a week for 10 minutes. Two experienced TT practitioners alternated treatments. At 26 days, metastasis to popliteal lymph nodes was determined by clonogenic assay. Changes in immune function were measured by analysis of serum cytokines and by fluorescent activated cells sorting (FACS) of immune cells from the spleen and lymph nodes. No significant differences were found in body weight gain or tumor size. Metastasis was significantly reduced in the TT-treated mice compared to mock-treated mice. Cancer significantly elevated eleven cytokines. TT significantly reduced IL-1-a, MIG, IL-1b, and MIP-2 to control/vehicle levels. FACS demonstrated that TT significantly reduced specific splenic lymphocyte subsets and macrophages were significantly elevated with cancer. Human biofield therapy had no significant effect on primary tumor but produced significant effects on metastasis and immune responses in a mouse breast cancer model.

    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{sup 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.

    Full Text Available Studies have shown that regular physical exercise of moderate intensity is an important tool for the control of pulmonary oxidative stress. The objective of this study was to examine the preventive and therapeutic effect of physical exercise on oxidative stress in the lungs of mice exposed to bleomycin (BLM. Thirty-six male mice (CF1, 30-35 g received a single endotracheal dose of BLM (2.5 U/kg body weight dissolved in 0.25 mL 0.9% NaCl or saline (0.9% NaCl and were divided into six groups (n=6: untrained saline or BLM, preventive training saline or BLM, and therapeutic training saline or BLM. The trained groups underwent a program of progressive exercise on a treadmill for 8 weeks (up to 17 m.min-1, 50 min.day-1. The preventive group started the exercise program 62 days before the administration of BLM and the therapeutic group 62 days after the administration of BLM. All animals were killed by decapitation 48 hours after the experimental period, and the right lung was surgically removed for the determination of biochemical parameters. Hydroxyproline content, TBARS level, protein carbonylation, and superoxide dismutase (SOD and catalase (CAT activities were analyzed. The results showed that preventive and therapeutic training led to a significant reduction in hydroxyproline content and inhibited the increase in oxidative damage to lipids and proteins. However, only therapeutic training decreased SOD and CAT activities in mice exposed to BLM. The results suggest that preventive and therapeutic physical exercise is able to minimize pulmonary oxidative stress induced by BLM.

    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.

    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

    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.

    The aim of this study was to assess the therapeutic effects of rosiglitazone with serial micro-CT findings before and after rosiglitazone administration in a lung fibrosis mouse model induced with bleomycin. We instilled the bleomycin solution directly into the trachea in twenty mice (female, C57BL/6 mice). After the instillation with bleomycin, mice were closely observed for 3 weeks and then all mice were scanned using micro-CT without sacrifice. At 3 weeks, the mice were treated with rosiglitazone on days 21 to 27 if they had abnormal CT findings (n = 9, 45%). For the mice treated with rosiglitazone, we performed micro-CT with mouse sacrifice 2 weeks after the rosiglitazone treatment completion. We assessed the abnormal CT findings (ground glass attenuation, consolidation, bronchiectasis, reticular opacity, and honeycombing) using a five-point scale at 3 and 6 weeks using Wilcoxon-signed ranked test. The micro-CT findings were correlated with the histopathologic results. One out of nine (11.1%) mice improved completely. In terms of consolidation, all mice (100%) showed marked decrease from 3.1 ± 1.4 at 3 weeks to 0.9 ± 0.9 at 6 weeks (p = 0.006). At 6 weeks, mild bronchiectasis (n = 6, 66.7%), mild reticular opacity (n 7, 77.8%) and mild honeycomb patterns (n = 3, 33.3%) appeared. A serial micro-CT enables the evaluation of drug effects in a lung fibrosis mouse model.

    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.

    Objective and design The objective of this study was to determine the ability of meloxicam prophylaxis and therapy to blunt the effect of complete Freund’s adjuvant (CFA) induced monoarthritis. Materials and methods First the validity of this animal model was established by examining joint changes at multiple levels after injecting CFA into the tibio-tarsal joint. Next, meloxicam (5 mg/kg) or vehicle was administered on days 0–7 (prophylactic) and on days 7–16 (therapeutic) in separate groups of animals. Results The CFA-injected joint demonstrated hallmark histological and structural changes such as pannus formation, bone remodeling, cartilage erosion and immune cell infiltration. Both prophylactic and therapeutic treatment with meloxicam effectively reduced swelling (ankle circumference), oedema and extravasation of Evans blue dye in the affected joint. Moreover, meloxicam reduced loss in range of motion and also reduced mechanical stimulus evoked pain scores. Notably, these effects persisted after discontinuing drug treatment. Conclusion The present study provides a unique comparison of prophylactic versus therapeutic effects of meloxicam in the CFA-induced model of monoarthritis. PMID:20349327

    Fulminant myocarditis (FM) is a life-threatening disease in children. With a rapid, progressive course of deterioration, it causes refractory cardiorespiratory failure even with optimal clinical intervention. We present the case of a 9-year-old girl with FM complicated by cardiogenic shock, malignant arrhythmia, and refractory cardiac arrest. She received effective cardiopulmonary resuscitation, therapeutic hypothermia, and other supportive treatments. However, the patient rapidly worsened into pulseless ventricular tachycardia and refractory cardiac arrest. Therefore, we performed extracorporeal membrane oxygenation (ECMO) to establish spontaneous circulation after the failure of standard resuscitation measures. The girl recovered with intact cardiac and neurocognitive functions after continued ECMO treatment for 221 hours. Therefore, ECMO is an effective rescue therapeutics for FM, especially when complicated with refractory cardiac arrest.

    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.

    Melanoma is a severe metastatic skin cancer with poor prognosis and no effective treatment. Therefore, novel therapeutic approaches using nanotechnology have been proposed to improve therapeutic effectiveness. Lipid-core nanocapsules (LNCs), prepared with poly(ε-caprolactone), capric/caprylic triglyceride, and sorbitan monostearate and stabilized by polysorbate 80, are efficient as drug delivery systems. Here, we investigated the effects of acetyleugenol-loaded LNC (AcE-LNC) on human SK-Mel-28 melanoma cells and its therapeutic efficacies on melanoma induced by B16F10 in C57B6 mice. LNC and AcE-LNC had z-average diameters and zeta potential close to 210 nm and -10.0 mV, respectively. CytoViva(®) microscopy images showed that LNC and AcE-LNC penetrated into SK-Mel-28 cells, and remained in the cytoplasm. AcE-LNC in vitro treatment (18-90×10(9) particles/mL; 1 hour) induced late apoptosis and necrosis; LNC and AcE-LNC (3-18×10(9) particles/mL; 48 hours) treatments reduced cell proliferation and delayed the cell cycle. Elevated levels of nitric oxide were found in supernatant of LNC and AcE-LNC, which were not dependent on nitric oxide synthase expressions. Daily intraperitoneal or oral treatment (days 3-10 after tumor injection) with LNC or AcE-LNC (1×10(12) particles/day), but not with AcE (50 mg/kg/day, same dose as AcE-LNC), reduced the volume of the tumor; nevertheless, intraperitoneal treatment caused toxicity. Oral LNC treatment was more efficient than AcE-LNC treatment. Moreover, oral treatment with nonencapsulated capric/caprylic triglyceride did not inhibit tumor development, implying that nanocapsule supramolecular structure is important to the therapeutic effects. Together, data herein presented highlight the relevance of the supramolecular structure of LNCs to toxicity on SK-Mel-28 cells and to the therapeutic efficacy on melanoma development in mice, conferring novel therapeutic mechanisms to LNC further than a drug delivery system.

  7. EXPERIMENTAL STUDY OF THE EFFECTIVENESS OF THE JOINT THERAPEUTIC ACTION OF LACTOGLOBULIN AND SALLMONELLA BACTERIOPHAGE

    Full Text Available The wide spread of drug-resistant forms of the pathogens, complicating prevention and treatment of acute intestinal infections, determines the feasibility of using bacteriophages and immune lactoglobulins for antibacterial therapy of these diseases. The aim of this study was to investigate the antibacterial efficacy of the joint use of immune lactoglobulin and Salmonella bacteriophage in the treatment of experimental salmonellosis in mice. The experimental Salmonella infection was reproduced by means of a single intragastric administration of 2LD50 of daily agar culture of S.typhimurium. As a result, the development of Salmonella infection lasting up to 14 days was noted. The animals were divided into four groups according to the pattern of the treatment. The following preparations were used for the treatment of animals: «Lactoglobulin against opportunistic bacteria and Salmonella» dry cow, «Lactoglobulin» liquid, bacteriophage of Salmonella ABCDE groups, liquid. The preparations were daily administered to mice orally after the infection for 7 days. In the study of the joint therapeutic effect of the lactoglobulin and bacteriophage the special attention was paid to the terms of elimination of the pathogen from animal organs. Analysis of the data showed that in all four groups a positive dynamics of excretion of the pathogen of mice was revealed. In groups of animals that were treated with both drugs, the elimination of Salmonella out of organs occurred 1.5 times faster than in the control groups of mice. At the same time in the experimental groups on the third day of treatment with preparations the statistically significant decrease in the number of S.typhimurium in the contents of the large intestine of animal was revealed. The study found that immune lactoglobulin used simultaneously with Salmonella phage for 7 days reduced the severity and duration of the disease course and blocked the further development of the infectious process

    In childhood and adolescence, some patients with cerebral palsy (CP) have long-term limited mobility, which can lead to secondary osteoporosis, Prevention and treatment strategies have been evaluated for the management of low bone mineral density (BMD) and fragility fractures. Currently, however, there are no established guidelines for the stratification and individualization of therapeutic interventions. Recently, an increasing number of studies have reported on the use of bisphosphonates to increase BMD in various pediatric conditions, and bisphosphonates have been suggested as a method to treat osteoporosis and prevent fractures. We performed the current meta-analysis to assess the effects of bisphosphonates on increasing BMD in children who have CP with secondary osteoporosis. A search of PubMed, Cochrane, and Embase from inception to April 2014 was performed with the following keywords: (bone disease, metabolic OR osteoporosis OR osteopenia) AND (child OR pediatric OR adolescent) AND (cerebral palsy) AND (bisphosphonate). Four studies were ultimately included in the meta-analysis: one randomized, double-blinded, placebo-controlled study and three case-controlled studies. The Z-score of lumbar spine was significantly improved after bisphosphonates treatment compared with pre-treatment values (standardized mean difference [SMD], 0.799; 95% confidence interval [CI], 0.499-1.100; pBisphosphonates have a significant effect on improving BMD in children with CP. Further standardization of treatment protocols including treatment dosage and duration needs to be established, and long-term follow up studies are needed.

    A variety of previous pharmacological studies have suggested that Liriope platyphylla may exert beneficial biological effects on inflammation, diabetes, neurodegenerative disorder, obesity, and atopic dermatitis (AD). The therapeutic effect of aqueous extract of Liriope platyphylla (AEtLP) on AD was quantified using the luciferase report system in IL-4/Luc/CNS-1 transgenic (Tg) mice. Alteration of the luciferase signal was quantified in IL-4/Luc/CNS-1 Tg mice co-treated with phthalic anhydride (PA) and AEtLP for 2 weeks using the IVIS imaging system. Phenotypes of AD were assessed by ear thickness analysis, measurement of immune-related organ weights, ELISA, and histological and pathological analysis in Tg mice. A strong luciferase signal was detected in the abdominal region of IL-4/Luc/CNS-1 Tg mice treated with only PA. However, this signal was significantly reduced in IL-4/Luc/CNS-1 Tg mice co-treated with PA+AEtLP in an AEtLP concentration-dependent manner. Especially, three organs, the thymus, pancreas, and submandibular lymph node (SL), showed a high signal response to PA treatment. Furthermore, to verify whether or not alteration of the luciferase signal is associated with AD, these disease response phenotypes were measured in the same group of mice. Common allergenic responses including increases in ear thickness, lymph node weight, IgE concentration, and infiltrated mast cells were detected in IL-4/Luc/CNS-1 Tg mice treated with PA. However, these responses were dramatically decreased by AEtLP treatment for 2 weeks. These results indicate that the luciferase signal may successfully reflect the therapeutic effects of AEtLP in IL-4/Luc/CNS-1 Tg mice. Further, we suggest additional evidence that Liriope platyphylla may be considered as an effective therapeutic drug for the treatment of AD. Copyright © 2013 Elsevier Ireland Ltd.

    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.

    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.

    Full Text Available The emergence and wide spread of multi-drug resistant Staphylococcus aureus (S. aureus requires the development of new therapeutic agents with alternative modes of action. Anti-virulence strategies are hoped to meet that need. Sortase A (SrtA has attracted great interest as a potential drug target to treat infections caused by S. aureus, as many of the surface proteins displayed by SrtA function as virulence factors by mediating bacterial adhesion to specific organ tissues, invasion of host cells, and evasion of the host-immune responses. It has been suggested that inhibitors of SrtA might be promising candidates for the treatment and/or prevention of S. aureus infections. In this study, we report that Chlorogenic acid (CHA, a natural compound that lacks significant anti–S. aureus activity, inhibit the activity of SrtA in vitro (IC50=33.86±5.55μg/ml and the binding of S. aureus to fibrinogen (Fg. Using molecular dynamics simulations and mutagenesis assays, we further demonstrate that CHA binds to the binding sites of C184 and G192 in the SrtA. In vivo studies demonstrated that CHA prevent mice from S. aureus-induced renal abscess, resulting in a significant survival advantage. These findings indicate that CHA is a promising therapeutic compound against SrtA during S. aureus infections.

    Vascular endothelial growth factor A (VEGF-A), commonly known as VEGF, is one of the primary factors that affect tumor angiogenesis. It was found to be expressed in cancer cell lines including oral squamous cell carcinoma. Photodynamic therapy (PDT) is a novel therapeutic modality to treat cancer by using a photosensitizer which is activated by a light source to produce reactive oxygen species and mediates oxygen-independent hypoxic conditions to tumor. Another emerging treatment to cure cancer is the use of interference RNA (e.g. siRNA) to silence a specific mRNA sequence. VEGF-A was found to be expressed in oral squamous cell carcinoma and overexpressed after 24 hour post-PDT by Western blot analysis. Cell viability was found to decrease at 25 nM of transfected VEGF-A siRNA. In vitro combined therapy of PDT and VEGF-A siRNA showed better response as compared with PDT and gene therapy alone. The results suggest that PDT combined with targeted gene therapy has a potential mean to achieve better therapeutic outcome.

    The present study aimed to compare the therapeutic efficiency of nano-encapsulated and nano-emulsion carvacrol administration on liver injury in thioacetamide (TAA) treated rats. To fulfill our target, we used sixty male albino rats classified into six groups as follow: control, nano-encapsulated carvacrol, nano-emulsion carvacrol, thioacetamide, treated nano-encapsulated carvacrol and treated nano-emulsion carvacrol groups. Blood samples were collected from all groups and the separated serum was used for analysis of the following biochemical parameters; aspartate aminotransferase (AST), alanine aminotransferase (ALT), S100 B protein, alpha fetoprotein (AFP) and caspase-3. The levels of malondialdehyde (MDA), reduced glutathione (GSH), nitric oxide (NO), monocyte chemoattractant protein-1(MCP-1) and hydroxyproline content were all evaluated in liver tissue homogenate. Histopathological examinations for liver tissues were also performed. Thioacetamide induced hepatic damage in rats as revealed by the significant increase in the levels of serum ALT, AST and produced oxidative stress as displayed by the significant elevation in the levels of hepatic MDA and NO concomitant with a significant decrease in GSH. In addition, thioacetamide significantly increased serum S100B protein, alpha fetoprotein and caspase-3 along with hepatic MCP-1 and hydroxyproline; these results were confirmed by the histopathological investigation. In contrast, nano-encapsulated and nano-emulsion carvacrol were able to ameliorate these negative changes in the thioacetamide injected rats. However, the effect of the nano-encapsulated form of carvacrol was more prominent than the nano-emulsion form. Nano-encapsulated and nano-emulsion carvacrol can ameliorate thioacetamide induced liver injury. These results could be attributed to the potential anti-inflammatory, antioxidant, and anti-apoptotic activities of carvacrol in addition to the effectiveness of the encapsulation technique that can protect

    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.

    Stem cell transplantation is a promising tool for the treatment of neurodegenerative disorders, including Parkinson's disease (PD); however, the therapeutic routes and mechanisms of mechanical approaches to stem cell transplantation must be explored. This study tests the therapeutic effect of transplantation of rat bone marrow mesenchymal stem cells (MSCs) into the substantia nigra (SN) of the PD rat. 5-Bromo-2-deoxyuridine-labeled rat MSCs were transplanted into the SN of the 6-hydroxydopamine-injected side of PD rat brains. The behavioral changes in PD rats were examined before and 4 and 8 weeks after MSC transplantation. The expression of tyrosine hydroxylase (TH) in the SN and the striatum and the survival and differentiation of MSCs were assessed by immunohistochemical and double immunofluorescence techniques. Abnormal behavior of PD rats was significantly improved by the administration of bone marrow MSCs, and the number of TH-positive cells in the SN and the optical density of TH-positive fibers in the striatum were markedly increased. Transplanted MSCs can survive and migrate in the brain and differentiate into nestin-, neuron-specific enolase-, and GFAP-positive cells. Our findings suggest that transplantation of rat bone marrow MSCs into the SN of PD rats may provide therapeutic effects. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    It is generally held that HIV, the causative agent of the rampaging global HIV/AIDS pandemic, is incurable and uniformly fatal. Since the discovery and isolation of the virus over two decades ago, global efforts at producing preventive and curative vaccines against it have so far resulted in failure. Working single-handedly with only his family's meagre resources and against the tide of universally accepted dogmas on HIV/AIDS, the author designed, developed and applied new HIV therapeutic and preventive vaccines in Nigeria, and has been using them on willing HIV-infected and normal persons respectively with their informed and written consent since their development. In many cases, the therapeutic vaccine produced rapid improvement not only in the symptoms and signs attributable to HIV infection, but also in various laboratory parameters with a sustained seroconversion to HIV antibody negative status in a number of the patients. In those HIV-infected patients with concomitant hepatitis B (HBV) and/or C (HCV) infection(s), the therapeutic vaccine has resulted in maintained seroconversion to negative (normal) for the HBsAg and HCV antibodies also. No significant adverse or side effect has been observed yet with the use of these vaccines. The vaccines do not cause the production of any detectable levels of stigmatizing anti-HIV antibodies. It is postulated that the vaccines elicit effective but selective cell-mediated cytotoxic immune responses against HIV, HBV and HCV-infected cells.

    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.

    This paper describes the evolution of vapour bubbles and its effect on nonlinear ultrasound propagation and temperature rise through tissues for therapeutic ultrasound. An acoustic-thermo coupling algorithm incorporating nonlinearity, diffraction, and temperature-dependent tissue properties, is employed to describe nonlinear ultrasound propagation and thermal effect. Results demonstrate that an obvious migration of peak pressure toward transducer surface is observed while the position of peak temperature changes little in liver tissue before the generation of vapour bubbles, and that the boiling region enlarges towards the surface of transducer in axial direction but increases slowly in radial direction after the generation of vapour bubbles.

    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.

It is often claimed that xylitol is superior to the other sugar alcohols for caries control. This paper examines clinical studies on the caries-preventive and therapeutic effects of sugar alcohols with emphasis on sorbitol and xylitol. It is concluded that chewing sugar-free gum 3 or more times daily for prolonged periods of time may reduce caries incidence irrespective of the type of sugar alcohol used. It may be sufficient to do this only on school days. Sucking xylitol-containing candies or tablets may have a similar effect as chewing xylitol chewing gum. Clinical trials suggest greater caries reductions from chewing gums sweetened with xylitol than from gums sweetened with sorbitol. However, the superiority of xylitol was not confirmed in 2 out of 4 clinical trials comparing the caries-preventive effect of xylitol- with sorbitol-sweetened gums. The caries-preventive effects of polyol-containing gums and candies seem to be based on stimulation of the salivary flow, although an antimicrobial effect cannot be excluded. There is no evidence for a caries-therapeutic effect of xylitol. These conclusions are in line with those of recent reviews and with the conclusions of the Scientific Committee on Medicinal Products and Medical Devices of the EU Commission. Copyright 2004 S.

    Therapeutic angiogenesis has emerged as an attractive approach for the management of peripheral arterial disease in diabetic patients. Oxidative stress generated and aggravated by prolonged hyperglycemia may interfere with and destroy the newly formed blood vessels. Angiogenic effect of simvastatin has been reported; however, its exact mechanism is yet to be evaluated. In addition, the exact role of antioxidant vitamins in diabetic peripheral arterial disease is still controversial. The present study was undertaken to investigate the therapeutic potential of simvastatin and antioxidant vitamins (E and C) and their combined effects on angiogenesis in diabetic hind-limb ischemia. Streptozotocin diabetic rats were treated for 6 weeks with simvastatin either alone or in combination with vitamin E or vitamin C. Parameters of angiogenesis, nitric oxide, heme oxygenase-1 (HO-1), and oxidative stress markers were evaluated. CD31 immunostaining revealed an increased capillary density in ischemic gastrocnemious tissue of diabetic rats treated with either simvastatin or its combination with vitamin C. This effect was accompanied by up-regulated plasma levels of HO-1, nitric oxide, vascular endothelial growth factor (VEGF) and its intra-muscular receptor type-2 (Flk-1). Tissue reduced glutathione and antioxidant enzymes activities were normalized in groups treated with antioxidant vitamins or their combination with simvastatin with concomitant blunting of lipid peroxidation. Vitamins E and C, through their antioxidant effects, evidently enhanced the angiogenic effect of simvastatin in ischemic diabetic muscle. Hence, the use of antioxidant vitamins combined with statins to induce therapeutic angiogenesis is a promising strategy in the management of diabetes-associated peripheral arterial disease.

    Tendinopathy is the most common tendon disorder. The etiology is still uncertain, and the disorder poses many therapeutic problems. In a few clinical studies, analgesic effects of high molecular weight hyaluronan (HMW HA) injections were observed, but the underlying mechanisms were not elucidated. In the present study, we analyzed the therapeutic effects of hyaluronan injections for tendinopathy in an animal model. We made the tendinopathy rat model using a rodent treadmill machine. Rats with tendinopathy were injected with HMW HA (HA group), normal saline (NS group), or nothing (control group) into the space between the patellar tendon and the fat pad bilaterally, or were injected with HMW HA into the right knees and with saline to the left knees (HA/NS group), 5 times every 4 days. To assess the pain-relieving effect of HA, the spontaneous locomotor activities at night (12 h) and weight bearing of hind paws were measured every day. Histological sections of the patellar tendon stained with hematoxylin-eosin or prepared by TdT-mediated dUTP nick end labeling were microscopically analyzed. The number of spontaneous locomotor activities in the HA group was significantly larger than those in NS or control groups, and in the HA group they recovered up to a healthy level. The percent weight distribution of the right hind paws was significantly increased along with the number of injections. On histologic examinations, the numbers of microtears, laminations, or apoptotic cells in the patellar tendons in the HA group were significantly lower than those in the NS or the control groups. The injections of HMW HA were effective for pain relief and for partial restoration of the patellar tendon in our tendinopathy rat model, and thus may become an effective therapeutic modality for the disease.

    A 55-year-old man with malignant pleural mesothelioma underwent multimodality treatment comprising induction chemotherapy followed by extrapleural pneumonectomy and radiation therapy. After 2.5 years, focal recurrence occurred, with computed tomography revealing a tumor in the left cardiophrenic angle. Surgery was considered a problem for the patient because of the previous extrapleural pneumonectomy and difficult tumor location. Radiofrequency ablation was thus performed; the course was uneventful, and there was no recurrence. Radiofrequency ablation should be considered an option to treat recurrence of malignant pleural mesothelioma. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    Approximately 80% of nursing home residents who suffer from Alzheimer's disease and related dementia develop behavioral symptoms of dementia. Given the deleterious side effects of pharmacologic therapy in this population there is an urgent need for clinical trials of nonpharmacologic interventions. To examine the effect of therapeutic touch on the frequency and intensity of behavioral symptoms of dementia. A randomized, double-blind, three-group experimental study: experimental (therapeutic touch), placebo (placebo therapeutic touch), and control (usual care). Fifty-seven residents, aged 67 to 93 years, exhibiting behavioral symptoms of dementia, were randomized to one of the three groups within each of three Special Care Units within three Long-Term Care facilities in a western Canadian province. Behavioral observation was completed every 20 minutes from 8:00AM to 6:00PM for three days pre-intervention and for three days post-intervention by trained observers who were blind to group assignment. The intervention consisted of therapeutic touch given twice daily for 5-7 minutes for three days between 10:00AM and 11:30PM and between 3:00PM and 4:30PM (N = 57). The main outcome variable was overall behavioral symptoms of dementia, consisting of six categories of behaviors: manual manipulation (restlessness), escape restraints, searching and wandering, tapping and banging, pacing and walking, and vocalization. Analysis of variance (ANOVA) (F = 3.331, P = .033) and the Kruskal-Wallis test (chi2 = 6.661, P = .036) indicated a significant difference in overall behavioral symptoms of dementia, manual manipulation and vocalization when the experimental group was compared to the placebo and control groups. The experimental (significant) was more effective in decreasing behavioral symptoms of dementia than usual care, while the placebo group indicated a decreasing trend in behavioral symptoms of dementia compared to usual care. Therapeutic touch offers a nonpharmacological

    2006-01-01

    Since the development of sophisticated molecular carriers such as octereotides for peptide receptor targeting and monoclonal antibodies against various associated with specific tumor types, radionuclide therapy (RNT) employing open sources of therapeutic agents is promising modality for treatment of tumors. Furthermore, the emerging of new therapeutic regimes and new approaches for tumor treatment using radionuclide are anticipated in near future. In targeted radiotherapy using peptides and other receptor based carrier molecules, the use of radionuclide with high specific activity in formulating the radiopharmaceutical is essential in order to deliver sufficient number of radionuclides to the target site without saturating the target. In order to develop effective radiopharmaceuticals for therapeutic applications, it is crucial to carefully consider the choice of appropriate radionuclides as well as the carrier moiety with suitable pharmacokinetic properties that could result in good in vivo localization and desired excretion. Up to date, only a limited number of radionuclides have been applied in radiopharmaceutical development due to the constraints in compliance with their physical half-life, decay characteristics, cost and availability in therapeutic applications. In this review article, we intend to provide with the improved understanding of the factors of importance of appropriate radionuclide for therapy with respect to their physical properties and therapeutic applications

    Shedding of the human NKG2D ligand MIC (MHC class I-chain-related molecule) from tumor cell surfaces correlates with progression of many epithelial cancers. Shedding-derived soluble MIC (sMIC) enables tumor immune escape through multiple immune suppressive mechanisms, such as disturbing natural killer (NK) cell homeostatic maintenance, impairing NKG2D expression on NK cells and effector T cells, and facilitating the expansion of arginase I+ myeloid suppressor cells. Our recent study has demonstrated that sMIC is an effective cancer therapeutic target. Whether targeting tumor-derived sMIC would enhance current active immunotherapy is not known. Here, we determined the in vivo therapeutic effect of an antibody co-targeting sMIC with the immunostimulatory IL-15 superagonist complex, ALT-803, using genetically engineered transplantable syngeneic sMIC+ tumor models. We demonstrate that combined therapy of a nonblocking antibody neutralizing sMIC and ALT-803 improved the survival of animals bearing sMIC+ tumors in comparison to monotherapy. We further demonstrate that the enhanced therapeutic effect with combined therapy is through concurrent augmentation of NK and CD8 T cell anti-tumor responses. In particular, expression of activation-induced surface molecules and increased functional potential by cytokine secretion are improved greatly by the administration of combined therapy. Depletion of NK cells abolished the cooperative therapeutic effect. Our findings suggest that administration of the sMIC-neutralizing antibody can enhance the anti-tumor effects of ALT-803. With ALT-803 currently in clinical trials to treat progressive solid tumors, the majority of which are sMIC+, our findings provide a rationale for co-targeting sMIC to enhance the therapeutic efficacy of ALT-803 or other IL-15 agonists.

    The fertilizing potential of treated municipal wastewater (oxidation ditch) and crop sanitary acceptability for direct human consumption were evaluated in Mendoza, Argentina. Two experiments were performed on a pilot plot planted with garlic (1998) and onions (1999) using furrow irrigation with three types of water in 10 random blocks: treated effluent (2.5 x 10(3) MPN Escherichia coli/100 ml, 3 helminth eggs/l, and Salmonella (positive); and well water (free of microorganisms), with and without fertilizer. Two responses were evaluated: (1) crop yield, and (2) crop microbiological quality for human consumption at different times after harvest. Crop yields were compared using Variance analysis. Crops' sanitary acceptability was assessed using a two-class sampling program for Salmonella (n=10; c=0), and a three-class program for E. coli (n=5, c=2, M=10(3) and m=10 MPN/g) as proposed by the International Commission on Microbiological Specifications for Foods (ICMSF) for fresh vegetables. Wastewater irrigation acted as well water with fertilizer, increasing garlic and onion yields by 10% and 15%, respectively, compared to irrigation with well water with no fertilizer. Wastewater-irrigated garlic reached sanitary acceptability 90 days after harvest, once attached roots and soil were removed. Onions, which were cleaned immediately after harvest, met this qualification earlier than garlic (55 days). Neither the wastewater-irrigated crops nor the control crops were microbiologically acceptable for consumption raw at harvest.

    In order to determine whether therapeutic riding could result in higher levels of stress than recreational riding, hypothalamic-pituitary-adrenal (HPA) axis response was evaluated in six horses by monitoring circulating β-endorphin, ACTH and cortisol concentrations. Horses were already accustomed to be trained both for therapy and riding school activity since 2004. Intervention consisted of 60-minute therapeutic sessions, two times per week for 6weeks with different riders: disabled and recreational riders (session A and B respectively). The therapeutic riders' group (A) consisted of six children with psychomotor disabilities; the recreational riders' group (B) consisted of six healthy children without any previous horse riding experience. Horses were asked to perform the same gaits and exercises at all sessions, both with disabled and healthy users. The statistical analysis showed that during both sessions the mean basal β-endorphin and ACTH levels of horses did not show any significant changes, while the one way RM-ANOVA showed significant effects of sessions A on the cortisol (F=11.50; PHorses submitted to sessions A showed lower cortisol levels both at 5min (Phorses and for the variables settled, HPA axis was less responsive to disabled than healthy, recreational riders. Among the endocrine responses, cortisol was one of the indicators of HPA axis stress response. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available The aim of this study was to investigate the influence of therapeutic dose X rays on the microhardness (MH and degree of conversion (DC of two different esthetic restorative dental materials. The materials were photo-activated with a LED light-curing unit using three cure-times: 5, 20 and 40 seconds. The photo-activation was carried out in two distinct periods: before and after irradiation with doses of 5, 35 and 70 Gy, from a 6 MV X rays beam. In accordance with the methodology used, it was conclude that a therapeutic dose does not have a detrimental effect on the photoinitiator molecules, because the photo-activation occurred after they were irradiated. When the irradiation was applied before photo-activation, the materials showed MH improvement, but when photo-activation was performed after irradiation, there was less improvement. However, there was no correlation between MH and DC. Thus, a therapeutic dose applied to cured material can promote linking and breaking of chain bonds in a non-linear way.

    The aim of this study was to evaluate the effectiveness of therapeutic conversation intervention in group and caregiver sessions on the supporting role of caregivers. Caregivers of people with eating disorders are known to suffer major difficulties and are in great need of support. Unhelpful parental support strategies can delay the recovery of an individual with an eating disorder. Skill training interventions can equip parents with skills, guidance and techniques by helping them to be a support person and making them one of the most important links in the treatment process. The therapeutic conversation intervention consisted of five group and caregiver sessions and three booster sessions. The Calgary Family Assessment and Calgary Family Intervention Models, the Illness Beliefs Model and the New Maudsley Method were used as theoretical frameworks. The content of the intervention consisted of work on difficult behaviours, feelings and helpful strategies. The participants (n = 58) included primary and secondary caregivers of 12- to 24-year-old patients with eating disorders. Eight caregivers dropped out of treatment. This study had a quasi-experimental design with one pre- and two post-test measures. Between 90-96% of caregivers rated the therapeutic conversation intervention as supportive. Furthermore, the study revealed significant differences in caregiver emotional and cognitive support, illness beliefs, disruptive behaviour and quality of life, negative aspects of care giving demands and caregiver and patient behavioural difficulties after the intervention and/or at follow-up. Therapeutic conversation intervention with caregivers in group and private sessions proved to be beneficial. This outcome provides information for healthcare professionals on how they can help primary caregivers in their supporting role, which can, in turn, improve services in healthcare centres and psychiatric hospitals. © 2016 John Wiley & Sons Ltd.

    AIM: To explore the therapeutic role of globular adiponectin (gAd) in high-fat diet/streptozotocin (STZ)-induced type 2 diabetic rats with nonalcoholic fatty liver disease (NAFLD). METHODS: Seven rats were fed a basic diet (normal control group; NC) during the experiment. Experimental rats (14 rats) were given a high-fat diet for 4 wk and were then injected with STZ to induce type 2 diabetes mellitus (T2DM) and NAFLD. Half of the T2DM/NAFLD rats were randomly injected intraperitoneally with gAd for 7 d (gAd-treated group), while the other 7 rats (T2DM/NAFLD group) received 0.9% saline. Plasma biochemical parameters and insulin concentrations were measured. Liver histopathology was examined by hematoxylin-eosin staining. Insulin receptor expression in the liver was analyzed by immunohistochemical staining, Western blot and quantitative real-time reverse transcription polymerase chain reaction analysis. RESULTS: Compared to the control group, the T2DM/NAFLD group had increased levels of glucolipid and decreased levels of insulin. Plasma glucose and lipid levels were decreased in the gAd-treated group, while serum insulin levels increased. The expression of insulin receptor in the T2DM/NAFLD group increased compared with the NC group, and gAd downregulated insulin receptor expression in the livers of T2DM/NAFLD rats. Steatosis of the liver was alleviated in the gAd-treated group compared to the T2DM/NAFLD group (NAS 1.39 ± 0.51 vs 1.92 ± 0.51, P T2DM rats with NAFLD by promoting insulin secretion, mediating glucolipid metabolism, regulating insulin receptor expression and alleviating hepatic steatosis.

    Oral anticoagulation therapy with vitamin K antagonists (VKA) such as warfarin and acenocoumarol is recommended in patients with atrial fibrillation (AF) and risk factors for embolism. The quality of anticoagulation control with VKA may be assessed by the time in therapeutic range (TTR). In our country, there are no data available about the quality of anticoagulation in patients with AF. The primary goal of our study was to assess the level of effective anticoagulation in a multicenter network of anticoagulation clinics in Argentina, which included patients with nonvalvular AF (NVAF) treated with VKA oral anticoagulants. The TERRA trial is a multicenter, cross-sectional study involving 14 anticoagulation clinics that were invited to participate and recruit 100 consecutive patients with NVAF treated with VKA for more than 1 year. The international normalized ratio (INR) values were retrospectively obtained from patient charts, and TTR was calculated using the Rosendaal method. A total of 1190 patients were included in the analysis. Mean age was 74.9 ± 9.9 years, and 52.5% of the patients were male. Median TTR was 67.5% (interquartile interval 54-80). During 55% of the TTR, INR was >3. Interinstitution variability was substantial, with a range of 57.7% ± 17% to 87.7% ± 17%, P < .001. The 10th percentile of TTR was 41%, the 20th percentile was 50%, the 30th was 58%, and the 35th percentile was 60%. In 40% of patients, TTR was <70%. In this multicenter study, mean TTR values in patients with AF under VKA were similar to those in international therapeutic clinical trials (55%-65%). Marked variations among institutions were observed and, although average results obtained were high, one third of the patients exhibited a TTR below 60%. This cutoff value is conservative according to current recommendations, and guidelines suggest that when management with VKA cannot be improved, patients should be switched to direct oral anticoagulants. The addition of TTR calculation to

    Full Text Available Few studies have examined therapist effects and therapeutic alliance (TA in treatments for chronic fatigue syndrome (CFS. Therapist effects are the differences in outcomes achieved by different therapists. TA is the quality of the bond and level of agreement regarding the goals and tasks of therapy. Prior research suffers the methodological problem that the allocation of therapist was not randomized, meaning therapist effects may be confounded with selection effects. We used data from a randomized controlled treatment trial of 296 people with CFS. The trial compared pragmatic rehabilitation (PR, a nurse led, home based self-help treatment, a counselling-based treatment called supportive listening (SL, with general practitioner treatment as usual. Therapist allocation was randomized. Primary outcome measures, fatigue and physical functioning were assessed blind to treatment allocation. TA was measured in the PR and SL arms. Regression models allowing for interactions were used to examine relationships between (i therapist and therapeutic alliance, and (ii therapist and average treatment effect (the difference in mean outcomes between different treatment conditions. We found no therapist effects. We found no relationship between TA and the average treatment effect of a therapist. One therapist formed stronger alliances when delivering PR compared to when delivering SL (effect size 0.76, SE 0.33, 95% CI 0.11 to 1.41. In these therapies for CFS, TA does not influence symptomatic outcome. The lack of significant therapist effects on outcome may result from the trial's rigorous quality control, or random therapist allocation, eliminating selection effects.

    Successful cancer immunotherapy is confounded by the magnitude of the tumor burden and the presence of immunoregulatory elements that suppress an immune response. To approach these issues, 26 patients with advanced treatment refractory cancer were enrolled in a safety/feasibility study wherein a conventional treatment modality, intensity modulated radiotherapy (IMRT), was combined with dendritic cell-based immunotherapy. We hypothesized that radiation would lower the tumor burdens, decrease the number/function of regulatory cells in the tumor environment, and release products of tumor cells that could be acquired by intratumoral injected immature dendritic cells (iDC). Metastatic lesions identified by CT (computed tomography) were injected with autologous iDC combined with a cytokine-based adjuvant and KLH (keyhole limpet hemocyanin), followed 24 h later by IV-infused T-cells expanded with anti-CD3 and IL-2 (AT). After three to five days, each of the injected lesions was treated with fractionated doses of IMRT followed by another injection of intratumoral iDC and IV-infused AT. No toxicity was observed with cell infusion while radiation-related toxicity was observed in seven patients. Five patients had progressive disease, eight demonstrated complete resolution at treated sites but developed recurrent disease at other sites, and 13 showed complete response at various follow-up times with an overall estimated Kaplan-Meier disease-free survival of 345 days. Most patients developed KLH antibodies supporting our hypothesis that the co-injected iDC are functional with the capacity to acquire antigens from their environment and generate an adaptive immune response. These results demonstrate the safety and effectiveness of this multimodality strategy combining immunotherapy and IMRT in patients with advanced malignancies

The introduction of newer drugs and regimens to treat second- and third-line relapsed/refractory MM appears to provide clinical benefits by lengthening progression-free and overall survival and improving quality of life. However, only the addition of DAR or PAN may be considered cost-effective options according to commonly cited thresholds, and PAN+BOR+DEX results require cautious interpretation.

    Therapeutic plasma exchange (TPE) and double plasma molecular absorption system (DPMAS) were two extracorporeal liver support systems. Few studies compared their efficacy profile. This study was to compare the efficacy of TPE and DPMAS on acute-on-chronic liver failure (ACLF) caused by hepatitis B virus (HBV-ACLF). 60 HBV-ACLF patients were enrolled and prospectively studied. All patients received entecavir therapy, and were assigned to TPE group (n = 33) and DPMAS group (n = 27). Primary end-points were the effects of TPE and DPMAS on liver function and serum inflammatory markers. Serum procalcitonin, interleukin (IL)-6, and high sensitive C-reactive protein (hsCRP) were significantly elevated in patients with HBV-ACLF. TPE achieved significantly higher removal rates of total bilirubin (TBIL, P = .002), direct bilirubin (DBIL, P = .006), and hsCRP (P = .010) than DPMAS, but DPMAS displayed lower loss rate of albumin (P = .000). TPE and DPMAS resulted in similarly increased serum IL-6 levels and comparable 12-week survivals (P > .05). Multivariate analysis showed that hospital stay (Relative Risk [RR]: 1.062, 95% Confidence Interval [CI]: 1.011-1.115, P = .016), prothrombin time (RR: 1.346, 95% CI: 1.077-1.726, P = .010), and international normalized ratio (RR: 0.013, 95% CI: 0.006-0.788, P = .041) were independent predictors for 12-week survival. Both TPE and DPMAS treatments were well-tolerated. Compared to DPMAS, TPE was more efficient in eliminating TBIL, DBIL, and hsCRP, but it was associated with higher loss rate of albumin. TPE and DPMAS were similar in improving 12-week survivals in HBV-ACLF. © 2017 Wiley Periodicals, Inc.

    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)

    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.

    Although the plasma technology has long been applied to treat contact lenses, the effect of this treatment on the performance of drug-loaded contact lenses is still unclear. The objective of this work is to study the effect of nitrogen plasma treatment on two drug-loaded polymeric formulations which previously demonstrated to be suitable for therapeutic contact lenses: a poly-hydroxyethylmethacrylate (pHEMA) based hydrogel loaded with levofloxacin and a silicone-based hydrogel loaded with chlorhexidine. Modifications of the surface and the optical properties, and alterations in the drug release profiles and possible losses of the antimicrobial activities of the drugs induced by the plasma treatment were assessed. The results showed that, depending on the system and on the processing conditions, the plasma treatment may be beneficial for increasing wettability and refractive index, without degrading the lens surface. From the point of view of drug delivery, plasma irradiation at moderate power (200 W) decreased the initial release rate and the amount of released drug, maintaining the drug activity. For lower (100 W) and higher powers (300 W), almost no effect was detected because the treatment was, respectively, too soft and too aggressive for the lens materials. © 2014 Wiley Periodicals, Inc.

    The prevalence of allergic disorders including atopic dermatitis (AD) and food allergy (FA) has increased dramatically in pediatric populations, but there is no effective drug available for their management. Therefore, trials are required for the development of safe therapeutic agents such as herbal medicines. We determined whether orally administered Poria cocos bark (PCB) extract could exert immunosuppressive effects on allergic and inflammatory symptoms of AD and FA. For both AD, which was induced using house dust mite extract, and FA, which was induced by exposure to ovalbumin, model mice were orally treated with PCB extract for 62 days and 18 days, respectively. We also investigated the inductive effect of PCB extract on the generation and maintenance of Foxp3(+)CD4(+) regulatory T cells (Tregs). The symptoms of AD and FA were ameliorated by the administration of PCB extract. Furthermore, PCB extract inhibited the Th2-related cytokines and increased the population of Foxp3(+)CD4(+) Tregs in both AD and FA models. In ex vivo experiments, PCB extract promoted the functional differentiation of Foxp3(+)CD4(+) Tregs, which is dependent on aryl hydrocarbon receptor activation. Thus, PCB extract has potential as an oral immune suppressor for the treatment of AD and FA through the generation of Tregs.

    While intra-articular injection of sinomenine hydrochloride has a therapeutic effect on osteoarthritis, it has a short half-life, and is thermolabile and photolabile. The aim of this research was to evaluate the sustained-release of sinomenine hydrochloride from an injectable sinomenine hydrochloride and sodium hyaluronate compound (CSSSI) and its therapeutic effect in a rabbit model of osteoarthritis following intra-articular injection. An injectable compound consisting of 1% sodium hyaluronate and 2.5% sinomenine hydrochloride was prepared and kept as the experiment group, and 2.5% sinomenine hydrochloride was prepared and kept as the control group. The cumulative mass release was measured at different time points in each group in vitro. Sixty-five male Zelanian rabbits were randomly divided into five groups: 15 (30 knees) each for the control, sodium hyaluronate, sinomenine hydrochloride, and CSSSI groups respectively, and five (10 knees) for the modeling group. Papain was injected into both knees of each rabbit for model establishment. Subsequently, 0.2 ml of the corresponding drugs was injected into the articular cavities of the remaining experiment groups, while the control group was treated with 0.2 ml normal saline. All groups were treated once a week for 4 weeks. Seven days after the last treatment, knees were anatomized to perform pathological observations and Mankin's evaluation of the synovium. Four groups were compared using the SPSS 13.0 software package. In the in vitro sustained-release experiments, 90% of the drug was released in the experiment group 360 minutes following the injection. Comparison of the Mankin's evaluations of the four groups illustrated statistical discrepancies (P sodium hyaluronate/sinomenine hydrochloride groups, statistical significance was uniformly obtained. Moreover, sodium hyaluronate and sinomenine hydrochloride treatments showed significant improvement over the modeling control (P sodium hyaluronate vs. sinomenine

    The isolation and identification of the discrete plant cannabinoids in marijuana revived interest in analyzing historical therapeutic claims made for cannabis in clinical case studies and anecdotes. In particular, sources as old as the 11th and 15th centuries claimed efficacy for crude marijuana extracts in the treatment of convulsive disorders, prompting a particularly active area of preclinical research into the therapeutic potential of plant cannabinoids in epilepsy. Since that time, a large body of literature has accumulated describing the effects of several of the >100 individual plant cannabinoids in preclinical models of seizures, epilepsy, epileptogenesis, and epilepsy-related neuroprotection. We surveyed the literature for relevant reports of such plant cannabinoid effects and critically reviewed their findings. We found that acute CB 1 R agonism in simple models of acute seizures in rodents typically produces anti-convulsant effects whereas CB 1 R antagonists exert converse effects in the same models. However, when the effects of such ligands are examined in more complex models of epilepsy, epileptogenesis and neuroprotection, a less simplistic narrative emerges. Here, the complex interactions between (i) brain regions involved in a given model, (ii) relative contributions of endocannabinoid signaling to modulation of synaptic transmission in such areas, (iii) multi-target effects, (iv) cannabinoid type 1 and type 2 receptor signaling interactions and, (v) timing, (vi) duration and (vii) localization of ligand administration suggest that there is both anti-epileptic therapeutic potential and a pro-epileptic risk in up- and down-regulation of endocannabinoid signaling in the central nervous system. Factors such receptor desensitization and specific pharmacology of ligands used (e.g. full vs partial agonists and neutral antagonists vs inverse agonists) also appear to play an important role in the effects reported. Furthermore, the effects of several plant

    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.

    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

    This secondary data analysis examined effects of an abstinence contingency on participation in a therapeutic workplace. Participants exposed to a pay reset after drug use did not differ in overall attendance from participants who were not exposed to a pay reset after drug use; however, they initially worked less after a pay reset than participants who did not receive a pay reset, and their attendance increased as their pay increased. Overall participation was not influenced by the abstinence contingency, but transient decreases in attendance occurred. © 2016 Society for the Experimental Analysis of Behavior.

    We evaluated the effectiveness of manual pressure hemostasis after transfemoral coronary angiography in patients on therapeutic warfarin anticoagulation (international normalized ratio [INR] 2.0 to 3.0) compared with discontinuing warfarin > or =48 hours before the procedure (INR <2.0). There was a low incidence of small hematomas with either strategy (no significant difference) and no major vascular complications. No prolonged hospital stay due to an access site complication was observed, and no thromboembolic events occurred. In conclusion, transfemoral coronary angiography appears to be safe in patients on warfarin with an INR of 2.0 to 3.0).

    The polycystic ovary syndrome is a gynaecological disorder of endocrine origin, with an alarmingly growing prevalence among women of reproductive age. Although there is no doubt about the impact of its symptoms on the mental health of involved women, there are only a few studies addressing the psychological or psychiatric aspects of this disorder. Present review of literature discusses psychological and psychosocial effects associated with the symptoms (hair growth, infertility, sexual life, obesity, skin problems), possible comorbid psychiatric disorders (depression, anxiety, eating disorders), and possibilities of therapeutic interventions (diet, workout, psychotherapy, cosmetic interventions).

Ninety patients were randomized into 3 groups, 4 cases of them were dropped off. Finally, there were 29 cases in the combined therapy group with acupuncture and the decoction, 29 cases in the western medication group and 28 cases in the Chinese herbal medicine group in the statistical analysis. In the combined therapy group with acupuncture and the decoction, the decoction was prescribed recurrence rate. The therapeutic effects are better than the simple application of either Chinese herbal medicine or omeprazole. for oral administration. Additionally, acupuncture was applied to Neiguan (PC 6), Zusanli (ST 36), Zhongwan (CV 12), Ganshu (BL 18), Danshu (BL 19) and Taichong (LR 3). The decoction was applied one dose a day and acupuncture was once a day. In the western medication group, omeprazole capsules, 20 mg were prescribed for oral administration, twice a day. In the Chinese herbal medicine group, the decoction was simply applied. The treatment was 8 weeks in the 3 groups and the follow-up visit was 6 months. The score of reflux disorder questionnaire (RDQ) and the changes in esophageal mucosa under gastroscope were observed before and after treatment; the clinical therapeutic effects and recurrence rate were evaluated in the 3 groups. In 4 and 8 weeks of treatment, RDQ scores in the 3 groups were all reduced as compared with those before treatment (all P herbal medicine was lower than that in the western medication group ( P herbal medicine was lower than those in the western medication group and the Chinese herbal medicine group (both P herbal medicine group (all P <0.05).

    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

    Studies on therapeutic drug monitoring (TDM) of second-generation antipsychotics (SGAs) have provided conflicting results regarding the association between dose, plasma concentrations, and drug effect and have focused rather on analyzing how individual drugs work. No study has attempted to process data from different SGAs globally to offer a panoramic view of the utility of TDM in clinical practice, and data on patients with first-episode psychosis (FEP) are lacking. This study aimed to assess the relationship between dose, plasma concentrations, and drug effect in a sample of patients with FEP, regardless of the SGA prescribed. Data from 64 compliant patients treated with the same SGA during a 2-month follow-up were recorded. Clinical symptoms were assessed using the Positive and Negative Symptoms Scale and the Montgomery-Åsberg Depression Rating Scale. Adverse effects were rated using the Udvalg für Kliniske Undersogelser scale. SGA doses were standardized to chlorpromazine equivalents, and patients were classified into 3 different ranges according to their plasma concentrations (subtherapeutic, therapeutic, and supratherapeutic). Plasma concentration ranges were proportionally related to dose. Patients with supratherapeutic plasma concentrations were treated with doses significantly higher than those with subtherapeutic concentrations. Dose and plasma concentrations were not associated with early drug effect. TDM seems unable to accurately estimate the early effects of SGAs in FEP. Ours is the first study to categorize plasma concentrations of SGAs into ranges for joint processing of data from a larger number of patients.

    Current therapies for Parkinson's disease (PD) like l-dopa and dopamine (DA) agonists have declined efficacy after long term use. Therefore, research towards supplementary or alternative medication is needed. The implementation in PD can be expedited by application of compounds already used in the clinic. In this study the therapeutic effects of the psychoactive compounds Delta(9)-tetrahydrocannabinol (Delta(9)-THC) and modafinil were tested in the 1-methyl-1,2,3,6-tetrahydropyridine (MPTP)-marmoset model for PD. The anti-parkinson effects of Delta(9)-THC (4 mg/kg) and modafinil (100 mg/kg) in parkinsonian marmosets were assessed with two behavioral rating scales covering parkinsonian symptoms and involuntary movements and two test systems assessing the locomotor activity and hand-eye coordination. Delta(9)-THC improved activity and hand-eye coordination, but induced compound-related side-effects. Modafinil improved activity and observed parkinsonian symptoms but not hand-eye coordination. It can be concluded that both compounds have therapeutic values and could supplement existing therapies for PD.

    The therapeutic effects of intercessory prayer (IP) to the Judeo-Christian God, one of the oldest forms of therapy, has had little attention in the medical literature. To evaluate the effects of IP in a coronary care unit (CCU) population, a prospective randomized double-blind protocol was followed. Over ten months, 393 patients admitted to the CCU were randomized, after signing informed consent, to an intercessory prayer group (192 patients) or to a control group (201 patients). While hospitalized, the first group received IP by participating Christians praying outside the hospital; the control group did not. At entry, chi-square and stepwise logistic analysis revealed no statistical difference between the groups. After entry, all patients had follow-up for the remainder of the admission. The IP group subsequently had a significantly lower severity score based on the hospital course after entry (P less than .01). Multivariant analysis separated the groups on the basis of the outcome variables (P less than .0001). The control patients required ventilatory assistance, antibiotics, and diuretics more frequently than patients in the IP group. These data suggest that intercessory prayer to the Judeo-Christian God has a beneficial therapeutic effect in patients admitted to a CCU.

    Lung cancer is the leading cause of cancer deaths worldwide, and this makes it an attractive disease to review and possibly improve therapeutic treatment options. Surgery, radiation, chemotherapy, targeted treatments, and immunotherapy separate or in combination are commonly used to treat lung cancer. However, these treatment types may cause different side effects, and chemotherapy-based regimens appear to have reached a therapeutic plateau. Hence, effective, better-tolerated treatments are needed to address and hopefully overcome this conundrum. Recent advances have enabled biologists to better investigate the potential use of natural compounds for the treatment or control of various cancerous diseases. For the past 30 years, natural compounds have been the pillar of chemotherapy. However, only a few compounds have been tested in cancerous patients and only partial evidence is available regarding their clinical effectiveness. Herein, we review the research on using current chemotherapy drugs and natural compounds (Wortmannin and Roscovitine, Cordyceps militaris, Resveratrol, OSU03013, Myricetin, Berberine, Antroquinonol) and the beneficial effects they have on various types of cancers including non-small cell lung cancer. Based on this literature review, we propose the use of these compounds along with chemotherapy drugs in patients with advanced and/or refractory solid tumours. PMID:29130448

    1997-01-01

    A group of 103 patients were examined for radicular painful syndromes in lumbar discopathy and lumbar spondylosis. Fifty-eight were treated by placing them in spine-decompressing position, traction and therapeutic exercises. The group of 45 patients had additionally paravertebral blockade (steroid + a local anaesthetic). In the blockade group the therapeutic effects were better, with rapid reduction of acute pain, with wellbeing improvement and better comfort, which facilitated further stages of the treatment. This made possible shortening of hospital stay by 20%, on average, as compared with the group without blockade. In patients with shorter lasting radicular pains (below 2 months) the results after paravertebral blockade were significantly better than in cases with longer duration of pains (2-6 months).

    Full Text Available Neoadjuvant chemotherapy is the state-of-the-art treatment in advanced breast cancer. A correct visualization of the post-therapeutic tumor size is of high prognostic relevance. X-ray phase-contrast computed tomography (PC-CT has been shown to provide improved soft-tissue contrast at a resolution formerly restricted to histopathology, at low doses. This study aimed at assessing ex-vivo the potential use of PC-CT for visualizing the effects of neoadjuvant chemotherapy on breast carcinoma.The analysis was performed on two ex-vivo formalin-fixed mastectomy samples containing an invasive carcinoma removed from two patients treated with neoadjuvant chemotherapy. Images were matched with corresponding histological slices. The visibility of typical post-therapeutic tissue changes was assessed and compared to results obtained with conventional clinical imaging modalities.PC-CT depicted the different tissue types with an excellent correlation to histopathology. Post-therapeutic tissue changes were correctly visualized and the residual tumor mass could be detected. PC-CT outperformed clinical imaging modalities in the detection of chemotherapy-induced tissue alterations including post-therapeutic tumor size.PC-CT might become a unique diagnostic tool in the prediction of tumor response to neoadjuvant chemotherapy. PC-CT might be used to assist during histopathological diagnosis, offering a high-resolution and high-contrast virtual histological tool for the accurate delineation of tumor boundaries.

    Today, the fact that sensory integration difficulties with a neurological basis exist and that they seriously condition the development of those individuals who suffer from them is widely accepted and acknowledged as being obvious by the vast majority of professionals working in the field of community healthcare. However, less is known and there is more controversy about effective treatments that can be applied to them. This is because many professionals criticise the fact that there is not enough scientific evidence to prove, both quantitatively and empirically, the outcomes of the interventions implemented as alternatives to pharmacological therapy. Consequently, when the symptoms and repercussions on the quality of life deriving from a distorted sensory integration are really disabling for the person, pharmacological treatment is used as the only possible approach, with the side effects that this entails. The reason for this is largely the fact that little is known about other effective therapeutic approaches, such as occupational therapy based on sensory integration.

    Mitochondrial dysfunction is known as one of causative factors in ischemic stroke, leading to neuronal cell death. The present work was undertaken to investigate whether succinate induces neuron apoptosis by regulating mitochondrial morphology and function. In neurons, oxygen-glucose deprivation induced succinate accumulation due to the reversal of succinate dehydrogenase (SDH) activation, leading to mitochondrial fission. Kaempferol inhibited mitochondrial fission and maintained mitochondrial HK-II through activation of Akt, and thereby protected neurons from succinate-mediated ischemi injury. Knockdown of Akt2 with siRNA diminished the effect of kaempferol, indicating that kaempferol suppressed dynamin-related protein 1 (Drp1) activation and promoted HK-II mitochondrial binding dependently on Akt. Moreover, we demonstrated that kaempferol potentiated autophagy during oxygen and glucose deprivation, contributing to protecting neuron survival against succinate insult. In vivo, oral administration of kaempferol in mice attenuated the infract volume after ischemic and reperfusion (I/R) injury and reproduced the similar mitochondrial protective effect in the brain infract area. This study indicates that succinate accumulation plays a pivotal role in I/R injury-induced neuronal mitochondrial dysfunction, and suggests that modulation of Drp1 phosphorylation might be potential therapeutic strategy to protect neuron mitochondrial integrity and treat ischemic stroke.

    The aim of the study was to demonstrate the therapeutic effect of taurine against aluminum (Al)-induced neurological disorders in rats. Forty-two Wistar rats were randomly allotted into six groups: control (saline only), Al exposure (281.4 mg/kg/day for 1 month), Al + taurine (Al administration as previously plus taurine, doses were 200, 400 and 800 mg/kg/day, respectively, for the next 1 month) and prevention group (along with the Al administration as previously, 400 mg/kg/day taurine was treated for 1 month. During the next 1 month, rats were given taurine 400 mg/kg/day only). Starting from the sixth week, the body weight gain was significantly reduced in Al exposure group compared with saline (P taurine treatment (400, 800 mg/kg/day and prevention) significantly protected against Al-induced brain dysfunction (P taurine treatment partially reversed the deteriorated changes. The results suggested that taurine probably has neuroprotective effect against Al-induced learning, memory and brain neurotransmitters dysfunction.

    Objective: To explore the therapeutic effect and possible adverse side-effects of small dose of estradiol and progesterone on postmenopausal osteoporosis. Methods: Applying a GBD-928 mono-photon BMD radiometer, 68 women (past-menopausal over 3 years, age 52-59, body weight index 2 0.5 mg with MPA (medroxyprogesterone acetate) 0.5 mg daily. The medication laster for a whole years and BMD value was measured again. All subjects underwent gynecological physical examination, vaginal sonography, vaginal smear study and breast examination with infra-red ray both before and after the test period. Results: After one year medication, mean value of BMD in Group A was 0.49 ± 0.05, three percentage points higher than before. In Group B, this was 0.52 ± 0.06, another three percentage points higher. Ten Women with mild lobular hyperplasia and nine women with small uterine myoma ( 3 ) were all allocated to the hormone treated group. The lesions showed either little change or slight regression after the test period. Conclusion: Osteoporotic women receiving additional small doses of female hormones responded much better than those receiving calcium only. The WHI report which advised against HRT should be more critically studied

      Melasma is an irregular brown or grayish-brown symmetric facial hypermelanosis, often affecting women, especially those living in areas with intense ultraviolet radiation.   Comparison of therapeutic effects of 20% azelaic acid and 4% hydroquinone cream in the treatment of melasma.   Twenty-nine women with melasma were recruited. Fifteen patients were treated with 4% hydroquinone cream and 14 patients were treated with azelaic acid cream for 2 months. The cream was applied twice daily. A broad-spectrum sunscreen was used concomitantly by both groups. The Melasma Area Severity Index (MASI) scores were determined prior to treatment and at each follow-up.   The mean MASI score before treatment was 7.2 ± 3.2 in the hydroquinone group and 7.6 ± 3.5 in the azelaic acid group, with no significant difference between them (t-test, CI 95% = -2.9 to 2.2). One month after treatment, the mean MASI score reached 6.7 ± 3.4 with hydroquinone and 6.3 ± 3.4 with azelaic acid with no significant difference between them (t-test, CI 95% = -2.2 to 3). After 2 months' treatment, the MASI score was 6.2 ± 3.6 with hydroquinone and 3.8 ± 2.8 with azelaic acid, a significant statistical difference (t-test, CI 95% = 0.03-4.9).   In conclusion, this study suggests that 20% azelaic acid cream applied twice daily may be more effective than hydroquinone 4% in reducing mild melasma. However, because this was an open trial, it is suggested that further studies involving large groups of patients be conducted to achieve a more conclusive result. © 2011 Wiley Periodicals, Inc.

    Anxiety disorders are a common occurrence in today's society. There is interest from the community in the use of complementary therapies for anxiety disorders. This review examined the currently available evidence supporting the use of therapeutic touch in treating anxiety disorders. To examine the efficacy and adverse effects of therapeutic touch for anxiety disorders. We searched the Cochrane Collaboration Depression, Anxiety and Neurosis Controlled Trials Registers (CCDANCTR-Studies and CCDANCTR-References) (search date 13/01/06), the Controlled Trials website and Dissertation Abstracts International. Searches of reference lists of retrieved papers were also carried out and experts in the field were contacted. Inclusion criteria included all published and unpublished randomised and quasi-randomised controlled trials comparing therapeutic touch with sham (mimic) TT, pharmacological therapy, psychological treatment, other treatment or no treatment /waiting list. The participants included adults with an anxiety disorder defined by the Diagnostic and Statistical Manual (DSM-IV),the International Classification of Diseases (ICD-10), validated diagnostic instruments, or other validated clinician or self-report instruments. Two review authors independently applied inclusion criteria. Further information was sought from trialists where papers contained insufficient information to make a decision about eligibility. No randomised or quasi-randomised controlled trials of therapeutic touch for anxiety disorders were identified. Given the high prevalence of anxiety disorders and the current paucity of evidence on therapeutic touch in this population, there is a need for well conducted randomised controlled trials to examine the effectiveness of therapeutic touch for anxiety disorders.

With a rapid, progressive course of deterioration, it causes refractory cardiorespiratory failure even with optimal clinical intervention. We present the case of a 9-year-old girl with FM complicated by cardiogenic shock, malignant arrhythmia, and refractory cardiac arrest. She received effective cardiopulmonary resuscitation, therapeutic hypothermia, and other supportive treatments. However, the patient rapidly worsened into pulseless ventricular tachycardia and refractory cardiac arrest. Therefore, we performed extracorporeal membrane oxygenation (ECMO to establish spontaneous circulation after the failure of standard resuscitation measures. The girl recovered with intact cardiac and neurocognitive functions after continued ECMO treatment for 221 hours. Therefore, ECMO is an effective rescue therapeutics for FM, especially when complicated with refractory cardiac arrest.

    Full Text Available Scoliosis is a lateral curvature of the spine. It is the most common deformity of the immature spine. The essential goal of treatment is to allow patients with scoliosis to avoid cardiopulmonary and neurological problems, and to improve the patient's appearance and future quality of life. Kinesio Taping is a method used for treatment of various musculo-skeletal conditions. The effects of Kinesio Taping is to relieve pain or abnormal feeling on the skin and fascia, supports the muscle in movement, removes congestion of lymphatic fluid or hemorrhages under the skin, and corrects misalignment of the muscle, fascia, and joint. Forty adolescent females complain from scoliosis their ages ranged from 11 to 17 years old, and their BMI was from 15 to 25 kg/m². They were divided randomly into two groups. Group A received therapeutic exercises for scoliosis, while group B received therapeutic exercise in addition to kinesio taping. X ray plain used for measuring of Cobb’s angle and present pain intensity (Ppi for pain assessment before and after treatment. There was a significant reduction of Cobb's angle and pain intensity at post treatment at both groups (p<0.05. There were significant reduction p<0.0001 in Ppi and this significant reduction in favor of group B. There was no significant differences between both groups in Cobb’s angle. Exercises for scoliosis and exercises augmented by kinesio taping had a significant effects on reduction of both Cobb’s angle and pain intensity.

  4. Physical basis of adverse and therapeutic effects of low intensity microwave radiation.

    Science.gov (United States)

    Hyland, G J

    2008-05-01

    A physical basis of adverse and therapeutic effects of low intensity microwave radiation is presented based on the concept of oscillatory similitude between the frequency of an external microwave field (together with any lower frequency modulations thereof) and those of certain endogenous dipolar coherent excitations allied to aliveness, which play the role of 'tuned circuits' via which a living organism is electromagnetically sensitised in a non-linear way to external fields too weak to be able to cause heating. From this perspective, an external electromagnetic field affects a living system not as a toxin but rather by perturbing its endogenous electromagnetic activity. The possibility of adverse perturbation is illustrated by reference to the microwave fields used in mobile telecommunications whose signals interfere in a non-thermal way with biofunctionality--in particular, undermining the efficacy of processes that would otherwise afford natural protection against the development of pathology. Therapeutic modalities of microwave exposure, on the other hand, are illustrated using the example of microwave resonance therapy--which can be considered as an electromagnetic version of acupuncture, and as an example of 'quantum medicine'--whose normalising effect on a wide range of pathologies is striking, and which affords a novel alternative to conventional pharmacological interventions.

    To investigate the therapeutic effect and mechanism of the surgical treatment for cervical vertigo with cervical spondylosis. Thirty-five patients in Department of Orthopaedics, Peking Union Medical College Hospital, Peking Union Medical College, who received surgical treatment for cervical spondylosis concomitant with cervical vertigo from 2004 to 2013 were reviewed retrospectively. The preoperative cervical curvature index (CCI), slip distance and intervertebral angle, as well as the pre-and-postoperative Cobb angle were measured. The pre-and-postoperative degree of vertigo was reported according to the American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium standard. The therapeutic effect and mechanism for patients with different imaging features and thus underwent various surgical approaches were analyzed. The mean follow-up was 40.6 months. Cervical instability was found in 33 patients. 29 of 35 (82.9%) patients had a satisfied recovery from cervical vertigo. The difference in Cobb angle in pre- and postoperative neutral cervical X-ray images was positively associated with the improvement for the vertigo (Pearson's test, P spondylosis. Cervical sympathetic nerves may have played an important role in the cervical vertigo. Surgery may relieve the cervical vertigo accompanying the cervical spondylosis.

    Systemic lupus erythematosus commonly known as lupus is an intricate disorder with multiple organ involvement characterized primarily by inflammation caused due to deposition of immune-complexes formed by production of autoantibodies against nuclear, nucleolar as well as cytoplasmic self-antigens. Lack of availability of suitable treatments or treatments that are only symptomatic calls for investigation of possible modalities. Withania somnifera with its immunomodulatory properties is prescribed for arthritis in ayurveda. In the present study, the therapeutic effect of Withania somnifera pure root powder (at 1,000 and 500 mg/kg body weight) on pristane-induced Balb/c model of lupus was investigated to elucidate its remedial outcome on SLE. SLE-like symptoms are produced in the model of lupus: production of autoantibodies, proteinuria, nephritis as well as immune-complex deposition along with various other inflammatory markers such as formation of lipogranuloma, production of pro-inflammatory cytokines including interleukin-6 and tumor necrosis factor-α, nitric oxide and reactive oxygen species. Withania somnifera was found to have potent inhibitory effect on proteinuria, nephritis and other inflammatory markers. Humoral response, however, was found to be impervious. The potent reduction in inflammation in the present model of lupus suggests further investigation of this herb for its possible therapeutic use in SLE.

    Lopez-Morata, José Antonio; Olivares, Amparo; Alcaraz, Miguel

    Zoledronic acid is used in the treatment of cancer-related diseases, although its use has been associated with avascular osteonecrosis. To determine the possible protective effect of a range of antioxidant substances against the inhibition of human prostate epithelial cell growth (PNT2) and transgenic adenocarcinoma mouse prostate tumour cells (TRAMP-C1), in treatments combining zoledronic acid and ionising radiation (IR). Cell survival is studied via cell viability assays (MTT) for 2 cell lines in isolated and combined treatments with zoledronic acid and/or IR, as well as the effect of adding 3 antioxidant substances. Zoledronic acid displays a significant cytotoxic effect over PNT2 and TRAMP-C1 cells (P<.001). The administration of antioxidants together with the zoledronic acid shows a protective effect for normal prostate cells, yet not so for prostate tumour cells. However, the administration of rosmarinic acid and apigenin in treatments combined with zoledronic acid provides a protective effect from the harmful effects of applying ionizing radiation, not only for normal PNT2 cells, but also for tumour cells. The use of antioxidant substances decreases the cytotoxic effect of zoledronic acid over non-tumour cells, and as such could be used in benign diseases. Furthermore, in the combined treatment using ionising radiation, these antioxidants also produced a protective effect in tumour cells, thus reducing the therapeutic effect sought by combining the treatment with radiation.

    2002-10-01

    Agitated behavior in persons with Alzheimer's disease (AD) presents a challenge to current interventions. Recent developments in neuroendocrinology suggest that changes in the hypothalamic-pituitary-adrenal (HPA) axis alter the responses of persons with AD to stress. Given the deleterious effects of pharmacological interventions in this vulnerable population, it is essential to explore noninvasive treatments for their potential to decrease a hyperresponsiveness to stress and indirectly decrease detrimental cortisol levels. This within-subject, interrupted time-series study was conducted to test the efficacy of therapeutic touch on decreasing the frequency of agitated behavior and salivary and urine cortisol levels in persons with AD. Ten subjects who were 71 to 84 years old and resided in a special care unit were observed every 20 minutes for 10 hours a day, were monitored 24 hours a day for physical activity, and had samples for salivary and urine cortisol taken daily. The study occurred in 4 phases: 1) baseline (4 days), 2) treatment (therapeutic touch for 5 to 7 minutes 2 times a day for 3 days), 3) posttreatment (11 days), and 4) post- "wash-out" (3 days). An analysis of variance for repeated measures indicated a significant decrease in overall agitated behavior and in 2 specific behaviors, vocalization and pacing or walking, during treatment and posttreatment. A decreasing trend over time was notedfor salivary and urine cortisol. Although this study does not provide direct clinical evidence to support dysregulation in the HPA axis, it does suggest that environmental and behavioral interventions such as therapeutic touch have the potential to decrease vocalization and pacing, 2 prevalent behaviors, and may mitigate cortisol levels in persons with AD.

  13. Endocannabinoid system and psychiatry: in search of a neurobiological basis for detrimental and potential therapeutic effects

    Full Text Available Public concern on mental health has noticeably increased given the high prevalence of neuropsychiatric disorders. Cognition and emotionality are the most affected functions in neuropsychiatric disorders, i.e. anxiety disorders, depression and schizophrenia. In this review, most relevant literature on the role of the endocannabinoid (eCB system in neuropsychiatric disorders will be presented. Evidence from clinical and animal studies is provided for the participation of CB1 and CB2 receptors (CB1R and CB2R in the above mentioned neuropsychiatric disorders. CBRs are crucial in some of the emotional and cognitive impairments reported, although more research is required to understand the specific role of the eCB system in neuropsychiatric disorders. Cannabidiol (CBD, the main non-psychotropic component of the Cannabis sativa plant, has shown therapeutic potential in several neuropsychiatric disorders. Although further studies are needed, recent studies indicate that CBD therapeutic effects may partially depend on facilitation of eCB-mediated neurotransmission. Last but not least, this review includes recent findings on the role of the eCB system in eating disorders. A deregulation of the eCB system has been proposed to be in the bases of several neuropsychiatric disorders, including eating disorders. Cannabis consumption has been related to the appearance of psychotic symptoms and schizophrenia. In contrast, the pharmacological manipulation of this eCB system has been proposed as a potential strategy for the treatment of anxiety disorders, depression, and anorexia nervosa. In conclusion, the eCB system plays a critical role in psychiatry; however, detrimental consequences of manipulating this endogenous system cannot be underestimated over the potential and promising perspectives of its therapeutic manipulation.

    Corn stover is one of the main agricultural residues being considered as a cellulosic ethanol feedstock. This work evaluated the effectiveness of AFEX™(1) pretreatment for converting corn stover to fermentable sugars, both with and without pre-soaking in hydrogen peroxide. The compositional changes and enzymatic digestibility of AFEX-treated and H-AFEX-treated biomass were investigated. Results showed that most of the polysaccharides remained intact following each of these two methods. Compared with AFEX pretreatment, the H-AFEX process enhanced delignification and enzymatic hydrolysis yields of both glucose and xylose. The maximum glucan and xylan digestibility of H-AFEX process were 87.78% and 90.64%, respectively, and were obtained using 0.7 (w/w) water loading, 1.0 (w/w) ammonia loading, 0.5 (w/w) 30wt.% hydrogen peroxide loading, and 130°C for 10min. The results of the present work show that H-AFEX is a feasible pretreatment to improve the enzymatic saccharification of corn stover for bioethanol production. Copyright © 2013 Elsevier Ltd.

    Unfamiliar or sudden exercise can induce delayed onset muscle soreness (DOMS) within 12-24 h. So, several researchers have reported various interventions to treat DOMS. Massage is generally known to eliminate muscle fatigue. However, effect of massage after DOMS is still not clear. We investigated whether the massage is effective on pain and gait after DOMS. The participants were divided into a control group (n= 10) with DOMS and an experimental group (n= 11) with the massage treated after DOMS. We induced DOMS by taking isotonic exercise with going up and down 20 times in 5-story building. We applied the massage and assessment on gastrocnemius of dominant foot. The change of gait and pain was assessed using gaitrite and algometer. In the present results, the massage on gastrocnemius after DOMS showed significant difference in pain (Psoreness.

    Cancer is currently classified and treated using an approach based on tissue of origin. Ambiguous or incorrect diagnoses, however, are common and often go unnoticed. Clinical cancer sequencing can provide diagnostic precision, therapeutic direction, and hereditary cancer risk assessment. This report presents a patient with an initial diagnosis of metastatic pancreatic adenocarcinoma (PDA), a disease with a dismal prognosis. Tumor sequencing revealed genomic abnormalities inconsistent with PDA, instead suggesting serous ovarian cancer. This molecular rediagnosis was further refined by the identification of a BRCA2 truncating mutation in the tumor, subsequently confirmed to be a germline event. These findings prompted the initiation of platinum-based chemotherapy, which produced a life-altering response, and referral to genetic counseling for her offspring. These results suggest that clinical tumor sequencing can simultaneously clarify diagnoses, guide therapy, and inform familial risk, even in patients with end-stage metastatic disease, making the case for the development of specific strategies to deploy sequencing coupled with big data in oncology to improve clinical cancer management.

    Full Text Available Stem cell therapy has shown encouraging results for neurodegenerative diseases. The retina provides a convenient locus to investigate stem cell functions and distribution in the nervous system. In the current study, we investigated the therapeutic potential of bone marrow mesenchymal stem cells (MSCs by systemic transplantation in a laser-induced retinal injury model. MSCs from C57BL/6 mice labeled with green fluorescent protein (GFP were injected via the tail vein into mice after laser photocoagulation. We found that the average diameters of laser spots and retinal cell apoptosis were decreased in the MSC-treated group. Interestingly, GFP-MSCs did not migrate to the injured retina. Further examination revealed that the mRNA expression levels of glial fibrillary acidic protein and matrix metalloproteinase-2 were lower in the injured eyes after MSC transplantation. Our results suggest that intravenously injected MSCs have the ability to inhibit retinal cell apoptosis, reduce the inflammatory response and limit the spreading of damage in the laser-injured retina of mice. Systemic MSC therapy might play a role in neuroprotection, mainly by regulation of the intraocular microenvironment.

    A simple and robust methodology, dubbed Entangled Trajectories Hamiltonian Dynamics (ETHD), is developed to capture quantum nuclear effects such as tunneling and zero-point energy through the coupling of multiple classical trajectories. The approach reformulates the classically mapped second-order Quantized Hamiltonian Dynamics (QHD-2) in terms of coupled classical trajectories. The method partially enforces the uncertainty principle and facilitates tunneling. The applicability of the method is demonstrated by studying the dynamics in symmetric double well and cubic metastable state potentials. The methodology is validated using exact quantum simulations and is compared to QHD-2. We illustrate its relationship to the rigorous Bohmian quantum potential approach, from which ETHD can be derived. Our simulations show a remarkable agreement of the ETHD calculation with the quantum results, suggesting that ETHD may be a simple and inexpensive way of including quantum nuclear effects in molecular dynamics simulations.

    Dienogest is a novel synthesized progestin used for treatment of endometriosis. This is the first case report describing a therapeutic effect of dienogest on a gynecologic malignancy. The patient was a 44-year-old woman with advanced adenosarcoma arising from the endometriosis in the rectovaginal space and infiltrating the left pelvic wall, left ureter, rectum and vagina. The residual tumor after tumor debulking surgery was resistant to both chemotherapy and radiotherapy. Dienogest was used as a substitute for medroxyprogesterone acetate because of the presence of deep vein thrombosis. Based on the RECIST criteria, partial response was obtained with oral dienogest therapy at six months and the serum CA125 level also decreased from 70 U/ml to 16 U/ml. The tumor remained stable up to 21 months. Thromboembolism or other adverse effects did not occur during the dienogest therapy. Dienogest may be useful for the treatment of adenosarcoma arising from endometriosis.

    Objective: To evaluate the therapeutic effect of 89 Sr (a pure beta emitter) using Bremsstrahlung imaging in patients with multiple bone metastases. Methods: 89 Sr Bremsstrahlung imaging was performed 1-2 weeks after injection in 14 patients with bone metastases, using GE Camstar 3200 SPECT equipped with a medium-energy collimator. To improve resolution of imaging, authors selected suitable energy level and wide window width (a 95-100% energy window around 100 KeV). Results: Abnormal uptake was seen in all and was consistent with the results of 99m Tc-MDP imaging. According to this result, authors can realize localization, retention and metabolism of 89 Sr in body. Conclusion: Bremsstrahlung imaging is useful for clinical observation and estimating the curative effect and prognosis in pure beta emitter therapy such as 89 Sr. In addition, it can be helpful in determining dose of 89 Sr if a repeated therapy is needed

    We studied the effect of therapeutic doses of optical radiation on the hematological parameters of blood irradiated in vivo: hemoglobin concentration, hematocrit, and the number of erythrocytes in the peripheral blood of patients during courses of extracorporeal, overvein, and intravenous blood irradiation and after treatment. The reversible changes during the procedures were found to differ from the changes obtained after treatment completion. At the end of the treatment course, the hematological parameters had changed in different directions and became higher, the same, or lower than the initial parameters depending on the initial parameters and photoinduced changes in blood oxygenation. A compensatory effect was found for photohemotherapy on oxygen-dependent processes altering the oxygen inflow into cells as well as the generation of active oxygen species and their inhibition by antioxidant systems.

    Advanced modeling techniques and current computational capacity make full core TREAT simulations possible, with the goal of such simulations to understand the pre-test core and minimize the number of required calibrations. But, in order to simulate TREAT with a high degree of precision the reactor materials and geometry must also be modeled with a high degree of precision. This paper examines how uncertainty in the reported values of boron and graphite have an effect on simulations of TREAT.

    Numerous therapeutic strategies are used to treat leishmaniasis. The treatment of cutaneous leishmaniasis (CL) is solely depends on antimonate derivatives with safety issues and questionable efficacy and there is no fully effective modality to treat CL caused by Leishmania tropica and Leishmania braziliensis. There is no prophylactic vaccine available against any form of leishmaniasis. Immunotherapy for CL has a long history; immunotherapy trials of first and second generation vaccines showed promising results. The current article briefly covers the prophylactic vaccines and explains different immunotherapy strategies that have been used to treat leishmaniasis. This paper does not include experimental vaccines and only lays emphasis on human trials and those vaccines which reached human trials. Immunotherapy is currently used to successfully treat several disorders; Low cost, limited side effects and no possibility to develop resistance make immunotherapy a valuable choice especially for infectious disease with chemotherapy problems. Efforts are needed to explore the immunological surrogate marker(s) of cure and protection in leishmaniasis and overcome the difficulties in standardization of crude Leishmania vaccines. One of the reasons for anti-leishmaniasis vaccine failure is lack of an appropriate adjuvant. So far, not enough attention has been paid to develop vaccines for immunotherapy of leishmaniasis.

    Laparoscopic techniques have evolved, allowing increased capabilities within most subspecialties of general surgery, but have failed to gain traction managing injured patients. We hypothesized that laparoscopy is effective in the diagnosis and treatment of penetrating abdominal injuries. We retrospectively reviewed patients undergoing abdominal exploration following penetrating trauma at our Level 1 trauma center during a 6-year period from January 1, 2008, to December 31, 2013. Demographic and resuscitation data were obtained from our trauma registry. Charts were reviewed for operative details, hospital course, and complications. Hospital length of stay (LOS) and complications were primary end points. Patients were classified as having nontherapeutic diagnostic laparoscopy (DL), nontherapeutic diagnostic celiotomy (DC), therapeutic laparoscopy (TL), or therapeutic celiotomy (TC). TL patients were case-matched 2:1 with TC patients having similar intra-abdominal injuries. A total of 518 patients, including 281 patients (55%) with stab wounds and 237 patients (45%) with gunshot wounds, were identified. Celiotomy was performed in 380 patients (73%), laparoscopy in 138 (27%), with 44 (32%) converted to celiotomy. Nontherapeutic explorations were compared including 70 DLs and 46 DCs with similar injury severity. LOS was shorter in DLs compared with DCs (1 day vs. 4 days, p < 0.001). There were no missed injuries. Therapeutic explorations were compared by matching all TL patients 2:1 to TC patients with similar type and severity of injuries. Twenty-four patients underwent TL compared with 48 TC patients in the case matched group. LOS was shorter in the TL group than in the TC group (4 days vs. 2 days, p < 0.001). Wound infections were more common with open exploration (10.4% vs. 0%, p = 0.002), and more patients developed ileus or small bowel obstruction after open exploration (9.4% vs. 1.1%, p = 0.018). Laparoscopy is safe and accurate in penetrating abdominal injuries

    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.

    To evaluate the potential arthrographic effect of therapeutic ultrasound applied before magnetic resonance imaging (MRI) of the wrist. Subjects and methods: MRI of the wrist was performed in 6 asymptomatic volunteers before and after ultrasound therapy of the carpus. For each patient, ultrasound therapy was performed by a trained physiotherapist for 10 minutes, with doses titrated to the maximum tolerated without pain. The amount of fluid within the wrist joints before and after therapy was assessed subjectively by 2 reviewers, as well as objectively by digital analysis. Results: Subjective appraisal of the images indicated that after ultrasound therapy there was an increase in joint fluid within the distal radioulnar joint in 4 volunteers, the midcarpal joint in 4 and the radiocarpal joint in 2. Computerized digital analysis of joint fluid confirmed an average volumetric increase in wrist joint fluid of 52.8% in 3 of the volunteers. The discomfort of the therapy was graded as 1/10 by 5 of the subjects and 4/10 by a single subject. Conclusions: Therapeutic ultrasound may be a useful adjuvant tool in the noninvasive induction of joint fluid before MRI of the wrist. (author)

    This study was aimed at exploring the high intensity focused ultrasound(HIFU) therapeutic dosimetry and its biologic effect. In-vitro, bovine liver was immersed into 0.9% NS and degassed for application. The JC Model-focused ultrasound tumor therapeutic system was used in the experiment. The HIFU parameters were: frequency 1.6 MHz, depth 20 mm, acoustic power from 16.44 W to 196.32 W. Under each power, at radiating times from is to 20 s, bioptic specimens were obtained from all samples. The results showed when the acoustic power was equal to or higher than 179.96 W, only is of radiating is adequate to induce coagulative necrosis, and when the acoustic power was lower than 65.44 W, the radiating time to produce coagulative necrosis was about 7 s. In the range of 65.44-179.96 W, at each time when the acoustic power was set up with an increment of 16.36 W, the time to produce coagulative necrosis was 1-2 s shorter. The form of biological focal region (BFR) varied with the acoustic power and HIFU irradiation time. The size of BFR increased with the increase of HIFU irradiation dosage (acoustic power x exposure time). There is positive correlation between the size of BFR and the dosage of HIFU irradiation (y = 0.0164x(1.05591), R5 = 0.9238, P < 0.05).

    Full Text Available Psoriasis is a common skin disease accompanied by chronic inflammation. In previous studies, erythroid differentiation regulator 1 (ERDR1 was shown to have a negative correlation with proinflammatory cytokine IL-18. However, the role of ERDR1 in the inflammatory skin disease psoriasis has not been evaluated. In this study, to investigate the role of ERDR1 in psoriasis, recombinant ERDR1 was injected intraperitoneally into a psoriasis mouse model. Recombinant ERDR1 (rERDR1 significantly alleviated the symptoms of psoriasis-like skin inflammation and reduced the mRNA of various psoriasis-related markers, including keratin 14, S100A8, and Th17-related cytokines IL-17 and IL-22, suggesting that rERDR1 exerts therapeutic effects on psoriasis via the regulation of Th17 functions. Additionally, the expression of CCL20, a well-known Th17 attracting chemokine, was determined. CCL20 expression significantly decreased in the rERDR1-injected group compared with the vehicle (PBS-injected group. CCR6 expression in the psoriatic lesional skin was also decreased by rERDR1 administration, implying the inhibition of CCR6-expressing Th17 cell chemotaxis via the downregulation of CCL20. Taken together, this study provides the first evidence that ERDR1 may be a potential therapeutic target for psoriasis.

    2014-01-01

    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.

    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.

  17. Unraveling the Effect of Immunogenicity on the PK/PD, Efficacy, and Safety of Therapeutic Proteins

    Directory of Open Access Journals (Sweden)

    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.
