Administration of BMSCs with muscone in rats with gentamicin-induced AKI improves their therapeutic efficacy.

Directory of Open Access Journals (Sweden)

Pengfei Liu

Full Text Available The therapeutic action of bone marrow-derived mesenchymal stem cells (BMSCs in acute kidney injury (AKI has been reported by several groups. However, recent studies indicated that BMSCs homed to kidney tissues at very low levels after transplantation. The lack of specific homing of exogenously infused cells limited the effective implementation of BMSC-based therapies. In this study, we provided evidence that the administration of BMSCs combined with muscone in rats with gentamicin-induced AKI intravenously, was a feasible strategy to drive BMSCs to damaged tissues and improve the BMSC-based therapeutic effect. The effect of muscone on BMSC bioactivity was analyzed in vitro and in vivo. The results indicated that muscone could promote BMSC migration and proliferation. Some secretory capacity of BMSC still could be improved in some degree. The BMSC-based therapeutic action was ameliorated by promoting the recovery of biochemical variables in urine or blood, as well as the inhibition of cell apoptosis and inflammation. In addition, the up-regulation of CXCR4 and CXCR7 expression in BMSCs could be the possible mechanism of muscone amelioration. Thus, our study indicated that enhancement of BMSCs bioactivities with muscone could increase the BMSC therapeutic potential and further developed a new therapeutic strategy for the treatment of AKI.

2017-10-01

Full Text Available Testosterone has been linked to social status seeking in humans. The present study investigated the effects of testosterone administration on implicit and explicit preferences for status goods in healthy male participants (n = 64, using a double-blind, placebo-controlled, between-subjects design. We also investigated the interactive effect between second-to-fourth digit ratio (2D:4D; i.e., a proximal index of prenatal testosterone and testosterone treatment on status preferences. Results showed that testosterone administration has no discernable influence on self-reported willingness-to-pay (i.e., the explicit measure or implicit attitudes towards status goods. Individuals with lower 2D:4D (i.e., more masculine had more positive attitudes for high-status goods on an Implicit Association Task, and this association was abolished with testosterone administration. These data suggest interactive effects of acute testosterone administration and prenatal testosterone exposure on human social status seeking, and highlight the utility of implicit methods for measuring status-related behavior.

Administration of Ecclesiastical Temporal Goods in the Light of the Instructions of the Polish Episcopal Conference of 2015

Robert Kantor

2017-04-01

Full Text Available The mission of the Church is evangelisation and not acquisition of capital. It is good if the Church has sufficient financial means necessary to fulfil its mission. The Catholic Church has the inherent right, independently of any secular power, to acquire, retain, administer and alienate temporal goods, in pursuit of its proper objectives (can. 1254 of the Code of Canon Law. In order to fulfil its mission in the world, the Church needs to be supported by appropriate material goods and the freedom to administer them. The Code of Canon Law of 1983 introduced a new regulation regarding ecclesiastical property, so as to make sure that the Church could better suit the concept of a “poor Church” that, being in the need of economic resources to achieve its goals, focuses on the instrumental task of such resources: so that the faithful fulfilled their duty in the form of helping in maintaining the Church and its works as part of their fundamental rights and obligations related to the temporal goods; so that spiritual goal of ecclesiastical offices was emphasised and the revenues received were justly distributed. The Polish Episcopal Conference on 25 August 2015 approved the Instruction on the Administration of Ecclesiastical Temporal Goods. In the present article four points will be discussed: The right of the Church to the acquisition, holding and alienating of temporal goods; the Instruction of the Polish Episcopal Conference on the acquisition of temporal goods; the Instruction of the Polish Episcopal Conference on the administration of temporal goods and contracts; the Remuneration for priests.

2013-05-01

Perspectives for innovative pharmaceutical molecules and intravesical administration of pharmacological agents are presented in the present review carried out from a recent literature. This review of the literature was built by using the PubMed and ScienceDirect databases running 20keywords revealing 34publications between 1983 and 2012. The number of referenced articles on ScienceDirect has increased in recent years, highlighting the interest of scientists for intravesical drug administration and the relevance of innovating drug delivery systems. Different modalities of intravesical administration using physical (e.g., iontophoresis, electroporation) or chemical techniques (e.g., enzyme, solvent, nanoparticles, liposomes, hydrogels) based on novel formulation methods are reported. Finally, the development of biopharmaceuticals (e.g., bacillus Calmette-Guérin, interferon α) and gene therapies is also presented and analyzed in this review. The present review exhibits new development in the pipeline for emerging intravesical drug administration strategies. Knowledge of all these therapies allows practitioners to propose a specific and tailored treatment to each patient with limiting systemic side effects. Copyright © 2013 Elsevier Masson SAS.

Good versus poor therapeutic alliances with non-accepting parents of same-sex oriented adolescents and young adults: a qualitative study.

Science.gov (United States)

Shpigel, Maya S; Diamond, Gary M

2014-01-01

Therapeutic themes and processes associated with five good versus five poor parent-therapist alliances among a sample of non-accepting parents of sexual minority youth/young adults participating in family therapy were examined. The Consensual Qualitative Research approach was used to analyse of therapy notes and follow-up interviewsfrom good and poor alliances. In good alliances, parents adopted relationship building as a goal, considered essentialist causal attributions of same-sex orientation, acknowledged positive aspects of their child, and perceived the therapist as empathic and accepting. Parents with poor alliances rejected relationship building as a goal, rebuffed essentialist causal attributions, dismissed the possibility of their own coming out, nullified positive aspects of their child, sought to change their child's sexual orientation, blamed therapists for validating their child's same-sex orientation, and pressured therapists for information about their child. Clinical implications are discussed.

Good Teaching: Aligning Student and Administrator Perceptions and Expectations

2017-03-01

Full Text Available Literature attests to limited systematic inquiry into students’ conceptions of good teaching in higher education. Resultantly, there have been calls for engaging students in construing what makes good university teaching and in developing a richer conception of teaching excellence. This interpretivist study that is based on views of final year university students from six academic disciplines investigated students’ conceptions of good teaching at Makerere University in Uganda. Students conceived good teaching as being student-centred, demonstrating strong subject and pedagogical knowledge, being approachable, being responsive, being organised, and being able to communicate well. Most of the conceptions of good teaching hinge  on what the teacher does (the means rather than affording high quality student learning (an end. It can therefore been concluded that good teaching is a multi-dimensional construct that defies a single definition and cannot be assured and assessed using a single indicator.

Therapeutic administration of a recombinant human monoclonal antibody reduces the severity of chikungunya virus disease in rhesus macaques.

Directory of Open Access Journals (Sweden)

Rebecca Broeckel

2017-06-01

Full Text Available Chikungunya virus (CHIKV is a mosquito-borne virus that causes a febrile syndrome in humans associated with acute and chronic debilitating joint and muscle pain. Currently no licensed vaccines or therapeutics are available to prevent or treat CHIKV infections. We recently isolated a panel of potently neutralizing human monoclonal antibodies (mAbs, one (4N12 of which exhibited prophylactic and post-exposure therapeutic activity against CHIKV in immunocompromised mice. Here, we describe the development of an engineered CHIKV mAb, designated SVIR001, that has similar antigen binding and neutralization profiles to its parent, 4N12. Because therapeutic administration of SVIR001 in immunocompetent mice significantly reduced viral load in joint tissues, we evaluated its efficacy in a rhesus macaque model of CHIKV infection. Rhesus macaques that were treated after infection with SVIR001 showed rapid elimination of viremia and less severe joint infiltration and disease compared to animals treated with SVIR002, an isotype control mAb. SVIR001 reduced viral burden at the site of infection and at distant sites and also diminished the numbers of activated innate immune cells and levels of pro-inflammatory cytokines and chemokines. SVIR001 therapy; however, did not substantively reduce the induction of CHIKV-specific B or T cell responses. Collectively, these results show promising therapeutic activity of a human anti-CHIKV mAb in rhesus macaques and provide proof-of-principle for its possible use in humans to treat active CHIKV infections.

Seizures are a common cause of neurologic disease, and phenobarbital (PB) is the most commonly used antiepileptic drug. Chronic oral dosing can be challenging for cat owners, leading to poor compliance. The purpose of this study was to determine if the transdermal administration of PB could achieve serum PB concentrations of between 15 and 45 μg/ml in healthy cats. Nineteen healthy cats were enrolled in three groups. Transdermal PB in pluronic lecithin organogel (PLO) was applied to the pinnae for 14 days at a dosage of 3 mg/kg q12h in group 1 (n = 6 cats) and 9 mg/kg q12h in group 2 (n = 7 cats). Transdermal PB in Lipoderm Activemax was similarly applied at 9 mg/kg q12h for 14 days in group 3 (n = 6 cats). Steady-state serum PB concentrations were measured at trough, and at 2, 4 and 6 h after the morning dose on day 15. In group 1, median concentrations ranged from 6.0-7.5 μg/ml throughout the day (observed range 0-11 μg/ml). Group 2 median concentrations were 26.0 μg/ml (observed range 18.0-37.0 μg/ml). For group 3, median concentrations ranged from 15.0-17.0 μg/ml throughout the day (range 5-29 μg/ml). Side effects were mild. One cat was withdrawn from group 2 owing to ataxia and sedation. These results show therapeutic serum PB concentrations can be achieved in cats following chronic transdermal administration of PB in PLO at a dosage of 9 mg/kg q12h. More individual variation was noted using Lipoderm Activemax. Transdermal administration may be an alternative for cats that are difficult to medicate orally. © ISFM and AAFP 2014.

Long-Term Statin Administration Does Not Affect Warfarin Time in Therapeutic Range in Australia or Singapore

Directory of Open Access Journals (Sweden)

Nijole Bernaitis

2018-05-01

Full Text Available Background: Warfarin requires ongoing monitoring of the International Normalised Ratio (INR. This is because numerous factors influence the response, including drug interactions with commonly-prescribed medications, such as statins. The administration of statins with warfarin may change INR; however, there is limited information regarding the effects on warfarin control as measured by time in therapeutic range (TTR. Statins may also alter bleeds with warfarin, but there are conflicting reports demonstrating both increased and decreased bleeds, and limited data on diverse ethnic populations. Therefore, the aim of this study was to determine the effect of statin administration on warfarin control and bleeds in patients in Australia and Singapore. Methods: Retrospective data were collected for patients on warfarin between January and June 2014 in Australia and Singapore. Patient data were used to calculate TTR and bleed events. Concurrent statin therapy was assessed and comparisons of TTR and bleed incidence were made across patient subgroups. Results: Warfarin control in Australia and Singapore was not significantly affected by statins, as measured by TTR (83% and 58%, respectively, frequency of testing, and warfarin doses. In Australia, statin use did not significantly affect bleeds, whilst in Singapore the bleed incidence was significantly lower for patients on statins. Conclusions: Chronic concurrent administration of statins with warfarin does not adversely affect warfarin TTR in Australia or Singapore. In Singapore, patients on statins, compared to no statins, had a lower bleed incidence and this requires further investigation, especially given the potential genetic influences of ethnicity on both statin and warfarin metabolism.

Correlation of pharmacodynamic activity, pharmacokinetics, and anti-product antibody responses to anti-IL-21R antibody therapeutics following IV administration to cynomolgus monkeys

Full Text Available Abstract Background Anti-IL-21R antibodies are potential therapeutics for the treatment of autoimmune diseases. This study evaluated correlations between the pharmacodynamic (PD activity, pharmacokinetics, and anti-product antibody responses of human anti-IL-21R antibodies Ab-01 and Ab-02 following IV administration to cynomolgus monkeys. Methods The PD assay was based on the ability of recombinant human IL-21 (rhuIL-21 to induce expression of the IL-2RA gene in cynomolgus monkey whole blood samples ex vivo. Monkeys screened for responsiveness to rhuIL-21 stimulation using the PD assay, were given a single 10 mg/kg IV dosage of Ab-01, Ab-02, or a control antibody (3/group, and blood samples were evaluated for PD activity (inhibition of IL-2RA expression for up to 148 days. Anti-IL-21R antibody concentrations and anti-product antibody responses were measured in serum using immunoassays and flow cytometry. Results Following IV administration of Ab-01 and Ab-02 to cynomolgus monkeys, PD activity was observed as early as 5 minutes (first time point sampled. This PD activity had good correlation with the serum concentrations and anti-product antibody responses throughout the study. The mean terminal half-life (t1/2 was ~10.6 and 2.3 days for Ab-01 and Ab-02, respectively. PD activity was lost at ~5-13 weeks for Ab-01 and at ~2 weeks for Ab-02, when serum concentrations were relatively low. The estimated minimum concentrations needed to maintain PD activity were ~4-6 nM for Ab-01 and ~2.5 nM for Ab-02, and were consistent with the respective KD values for binding to human IL-21R. For Ab-01, there was noticeable inter-animal variability in t1/2 values (~6-14 days and the resulting PD profiles, which correlated with the onset of anti-product antibody formation. While all three Ab-01-dosed animals were positive for anti-Ab-01 antibodies, only one monkey (with the shortest t1/2 and the earliest loss of PD activity had evidence of neutralizing anti-Ab-01

Reimer, Andrew P; Madigan, Elizabeth A

2018-01-01

Veracity, one of the five V's used to describe big data, has received attention when it comes to using electronic medical record data for research purposes. In this perspective article, we discuss the idea of data veracity and associated concepts as it relates to the use of electronic medical record data and administrative data in research. We discuss the idea that electronic medical record data are "good enough" for clinical practice and, as such, are "good enough" for certain applications. We then propose three primary issues to attend to when establishing data veracity: data provenance, cross validation, and context.

The Role of National Ombudsman’s Offices in Promoting the Concept of good Administration in Albania, Macedonia and Kosovo. The way ahead

Full Text Available The private persons in any democratic state should have a right to dispute the administrative decisions affecting their rights, freedoms or interests before (among others competent independent courts. It is the key precondition for the principle of transparent and responsible public administration as an integral part of democratic governance. In addition to the “judiciary control of the administrative decisions”, the private persons` human rights against the public administration may be also protected through the Ombudsman office. The increasing importance of the afore mentioned issues relating public administration and the various types of control of the administrative acts been long time ago reflected in the mandate of almost all of the key international inter-governmental organizations, especially the European ones including the Council of Europe, the European Union and the OSCE. The establishment of both effective public administration and administrative justice system has been for a long period of time among the most “important and urgent” final strategic objectives of almost any country in the Balkans region, including Albania, Macedonia and Kosovo. This process included (among others establishing European-like Ombudsman offices in these countries. Against the above background the present paper firstly explains why the administration action must be controlled by the public, and it then outlines the European Right of Good Administration, the Ombudsman Office`s mandate. This is then followed by presenting the concept of European Administrative Space in terms of the Role of the OECD-SIGMA in Developing the Standards of Good Administration. Against the preceding sub-sections the paper further presents the basic legislative framework for action of the National Ombudsman Offices in Albania, Macedonia and Kosovo, which is then followed by a short review of the actual state of play of the Principle No.2 of the SIGMA European Principles for

Systemic Administration of Interleukin 2 Enhances the Therapeutic Efficacy of Dendritic Cell-Based Tumor Vaccines

Science.gov (United States)

Shimizu, K.; Fields, R. C.; Giedlin, M.; Mule, J. J.

1999-03-01

We have reported previously that murine bone marrow-derived dendritic cells (DC) pulsed with whole tumor lysates can mediate potent antitumor immune responses both in vitro and in vivo. Because successful therapy was dependent on host immune T cells, we have now evaluated whether the systemic administration of the T cell stimulatory/growth promoting cytokine interleukin-2 (IL-2) could enhance tumor lysate-pulsed DC-based immunizations to further promote protective immunity toward, and therapeutic rejection of, syngeneic murine tumors. In three separate approaches using a weakly immunogenic sarcoma (MCA-207), the systemic administration of non-toxic doses of recombinant IL-2 (20,000 and 40,000 IU/dose) was capable of mediating significant increases in the potency of DC-based immunizations. IL-2 could augment the efficacy of tumor lysate-pulsed DC to induce protective immunity to lethal tumor challenge as well as enhance splenic cytotoxic T lymphocyte activity and interferon-γ production in these treated mice. Moreover, treatment with the combination of tumor lysate-pulsed DC and IL-2 could also mediate regressions of established pulmonary 3-day micrometastases and 7-day macrometastases as well as established 14- and 28-day s.c. tumors, leading to either significant cure rates or prolongation in overall survival. Collectively, these findings show that nontoxic doses of recombinant IL-2 can potentiate the antitumor effects of tumor lysate-pulsed DC in vivo and provide preclinical rationale for the use of IL-2 in DC-based vaccine strategies in patients with advanced cancer.

Evidence for the beneficial effect of therapeutic burst-suppression coma in pediatric patients with febrile refractory status epilepticus is limited, and the clinical outcomes of this treatment strategy are largely unknown. Therefore, the aim of this study was to explore the outcomes of therapeutic burst-suppression coma in a series of children with febrile refractory status epilepticus. We retrospectively reviewed consecutive pediatric patients with febrile refractory status epilepticus admitted to our pediatric intensive care unit between January 2000 and December 2013. The clinical characteristics were analyzed. Thirty-five patients (23 boys; age range: 1-18years) were enrolled, of whom 28 (80%) developed super-refractory status epilepticus. All of the patients received the continuous administration of intravenous antiepileptic drugs for febrile refractory status epilepticus, and 26 (74.3%) achieved therapeutic burst-suppression coma. All of the patients received mechanical ventilatory support, and 26 (74.3%) received inotropic agents. Eight (22.9%) patients died within 1month. The neurologically functional outcomes at 6months were good in six (27.3%) of the 22 survivors, of whom two returned to clinical baseline. The patients with therapeutic burst-suppression coma were significantly associated with hemodynamic support than the patients with electrographic seizures control (p=0.03), and had a trend of higher 1-month mortality rate, worse 6months outcomes, and a longer duration of hospitalization. Our results suggest that therapeutic burst-suppression coma to treat febrile refractory status epilepticus may lead to an increased risk of hemodynamic instability and a trend of worse outcomes.

Sepsis is still a major cause of death and many efforts have been made to improve the physical condition of sepsis patients and to reduce the high mortality rate associated with this disease. While achievements were implemented in the intensive care treatment, all attempts within the field of novel therapeutics have failed. As a consequence new medications and improved patient stratification as well as a thoughtful management of the support therapies are urgently needed. In this study, we investigated the simultaneous administration of ibuprofen as a commonly used nonsteroidal anti-inflammatory drug (NSAID) and Pep19-2.5 (Aspidasept), a newly developed antimicrobial peptide. Here, we show a synergistic therapeutic effect of combined Pep19-2.5-ibuprofen treatment in an endotoxemia mouse model of sepsis. In vivo protection correlates with a reduction in plasma levels of both tumor necrosis factor α and prostaglandin E, as a likely consequence of Pep19-2.5 and ibuprofen-dependent blockade of TLR4 and COX pro-inflammatory cascades, respectively. This finding is further characterised and confirmed in a transcriptome analysis of LPS-stimulated human monocytes. The transcriptome analyses showed that Pep19-2.5 and ibuprofen exerted a synergistic global effect both on the number of regulated genes as well as on associated gene ontology and pathway expression. Overall, ibuprofen potentiated the anti-inflammatory activity of Pep19-2.5 both in vivo and in vitro, suggesting that NSAIDs could be useful to supplement future anti-sepsis therapies. PMID:26197109

Full Text Available Abstract The objectives of the professional agencies must embody provisions that promote good governance and embrace values of integrity and accountability and seek support from the public and the government of the day to provide an independent view on all matters. The universal truth is that everything should be done in the public good. Professionals form the backbone of human infrastructure in any economy, politics, social and legal growth. Their contributions through professional performance enhance the good delivery system that facilitates policies making and management for public sector. They provide the skills and talent in balancing the pursuits of maximization of services. The expression “good governance” has been constantly used lately in both public sector as well as private sector in Malaysia. In the context of a private body, it should be within the framework of the statute, which governs the body and also its constitution. In the public sector, it means that the administrators should act professionally and not to abuse or misuse the power or authority given to them. They are regarded as the trustees of the public at large. The scope of this article is on good public governance in the public sector or to be exact, good governmental administration as interpreted by the judiciary especially through its judicial review power and Islamic Perspective based on the principles of Maqasid As Shariah (Objectives of Islamic Law.   Keywords: Good Governance, Public Sector, Malaysian Law, Islamic Perspective, Maqasid As-Shariah.

Johnson, Matthew W; Griffiths, Roland R

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

Full Text Available Background: The goal of antivenom administration for snake-bitten patients is to achieve therapeutic response (initial control, which means reversal of the venom-induced effects through neutralizing the venom. The aim of this study was to identify snakebite prognostic factors of weak therapeutic response prior to antivenom administration. Methods: This was a retrospective study of patients with viperidae snakebite envenomation who were admitted to Mashhad Toxicology Centre during 2007-2011. Demographic features, clinical manifestations and snakebite severity score (SSS were collected prior to antivenom administration. Total number of antivenom vials administered to achieve therapeutic response and duration of hospitalization were also recorded. Potential factors in snakebite prognosis were analyzed by comparing in two groups of achieving therapeutic response with less than 5 vials and over 5 to calculate odds ratio.  Results: Total of 108 patients (male/female: 85/23 with mean (SD age of 34.5 (17.0 were studied. The most common manifestations included fang marks (100%, pain (100%, ecchymosis (89%, swelling (83%, blister formation (48% and thrombocytopenia (25%. In univariate analysis, thrombocytopenia (P=0.01, spontaneous bleeding (P=0.02, coagulopathic disturbances (P=0.007, swelling (P=0.003, progressive swelling (P=0.005, ecchymosis (P=0.05 and respiratory distress (P= 0.05 were significantly correlated to weak therapeutic response. Swelling and spontaneous bleeding were the strongest snakebite prognostic factors, as respectively they put the patients at 12.4 and 10.4 fold risks for difficult achievement of therapeutic response. Conclusions: In snakebite, some clinical manifestations in the first hours of admission and prior to antivenom administration are associated with weak therapeutic response. Identifying these prognostic factors, can assist health care providers to better estimate the patient’s needs and predict the final

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

Therapeutic Nanodevices

Lee, Stephen; Ruegsegger, Mark; Barnes, Philip; Smith, Bryan; Ferrari, Mauro

Therapeutic nanotechnology offers minimally invasive therapies with high densities of function concentrated in small volumes, features that may reduce patient morbidity and mortality. Unlike other areas of nanotechnology, novel physical properties associated with nanoscale dimensionality are not the raison d'être of therapeutic nanotechnology, whereas the aggregation of multiple biochemical (or comparably precise) functions into controlled nanoarchitectures is. Multifunctionality is a hallmark of emerging nanotherapeutic devices, and multifunctionality can allow nanotherapeutic devices to perform multistep work processes, with each functional component contributing to one or more nanodevice subroutine such that, in aggregate, subroutines sum to a cogent work process. Cannonical nanotherapeutic subroutines include tethering (targeting) to sites of disease, dispensing measured doses of drug (or bioactive compound), detection of residual disease after therapy and communication with an external clinician/operator. Emerging nanotherapeutics thus blur the boundaries between medical devices and traditional pharmaceuticals. Assembly of therapeutic nanodevices generally exploits either (bio)material self-assembly properties or chemoselective bioconjugation techniques, or both. Given the complexity, composition, and the necessity for their tight chemical and structural definition inherent in the nature of nanotherapeutics, their cost of goods (COGs) might exceed that of (already expensive) biologics. Early therapeutic nanodevices will likely be applied to disease states which exhibit significant unmet patient need (cancer and cardiovascular disease), while application to other disease states well-served by conventional therapy may await perfection of nanotherapeutic design and assembly protocols.

Microwave bio-sensor based on symmetrical split ring resonator with spurline filters for therapeutic goods detection.

Directory of Open Access Journals (Sweden)

Rammah A Alahnomi

Full Text Available A novel symmetrical split ring resonator (SSRR based microwave sensor with spurline filters for detecting and characterizing the properties of solid materials has been developed. Due to the weak perturbation in the interaction of material under test (MUT and planar microwave sensor, spurline filters were embedded to the SSRR microwave sensor which effectively enhanced Q-factor with suppressing the undesired harmonic frequency. The spurline filter structures force the presented sensor to resonate at a fundamental frequency of 2.2 GHz with the capabilities of suppressing rejected harmonic frequency and miniaturization in circuit size. A wide bandwidth rejection is achieved by using double spurlines filters with high Q-factor achievement (up to 652.94 compared to single spurline filter. The new SSRR sensor with spurline filters displayed desired properties such as high sensitivity, accuracy, and performance with a 1.3% typical percentage error in the measurement results. Furthermore, the sensor has been successfully applied for detecting and characterizing solid materials (such as Roger 5880, Roger 4350, and FR4 and evidently demonstrated that it can suppress the harmonic frequency effectively. This novel design with harmonic suppression is useful for various applications such as food industry (meat, fruit, vegetables, biological medicine (derived from proteins and other substances produced by the body, and Therapeutic goods (antiseptics, vitamins, anti-psychotics, and other medicines.

Several physicians considering the possibility of stunning or under rhTSH stimulation, indicate the administration of high activities of 131 I with the uncertainty of the existence of normal or pathological thyroid tissue concentrating radioiodine. This procedure reach its maximum score in the so called 'shoot in the dark' (SD). Other groups of physicians and the medical physics, considering the increasing radio sanitary risk and the dubious results of the use of SD, are not in agree with this position. A third position is the utilization of 123 I, that remains out of possibilities for the majority of the nuclear medicine laboratories. In a effort to conciliate these mismatched positions we propose the following procedure utilizing 99m Tc as pertechnetate, as its radiation dose is negligible compared with dose of radioiodines. We study 2 groups of patients DTC, G-A, 6 patients, 5 female, 1 male, 39-56 years old; with indication of 131 I administration for follow up or therapeutic purposes, 2 with rhTSH stimulation and 4 withdrawing hormone therapy; G-B, 5 patients, 4 females 1 male, 32-92 years old, with indication of scintigraphy previous to 131 I ablation post surgery. In both groups, previous to radioiodine, the same day, 370 MBq of 99m Tc pertechnetate was administered iv and a whole body scan (WBS) and uptake (Up) of positive areas were carried out. Immediately radioiodine was administered, 148 MBq in G-A and 11.1 MBq in G-B and WBS and Up were performed at 48 and 24 hours respectively. In all patients serum figures of TSH, Tg and antibodies anti Tg were obtained. The images obtained with both radioactive tracer were similar in all cases, as well as the active areas with positive uptake values. The Up for both tracer in positive areas was different in agree with the differences in the mechanism of concentration and metabolic behavior. These preliminary results allow us to considered that 99m Tc Up and WBS could be used top determine the possibility of 131 I

2009-01-01

The absorbed dose to tumors after systemic administration of radiopharmaceuticals is not sufficient to achieve acceptable levels of probability of tumor control without compromising on critical tissue toxicity (kidney and / or bone marrow (BM)). There are reports of trials with multiple administrations, about tolerance level inter-administration intervals to allow recovery of the BM, with good results. The biokinetic behavior of some radiopharmaceuticals known makes possible the application of several administrations with short intervals of time.It is the present work combines two kinetic models of tumor growth and cell kinetics in the BM for predicting the response to continuous irradiation at low dose rate. The estimation of the effects of irradiation on tumor and kidneys was done using a formulation of the linear-quadratic model functions suitable for dose rate and multi-exponential repair. The estimation of the response in WB performed using a compartmental model previously reported. The absorbed dose to organs were calculated using the MIRD formulation taking into account the effect of irradiation cross. Biokinetic data were used for therapeutic radiopharmaceuticals 90Y, 131I and 177Lu, as well as radiobiological parameters reported for experimental animals. The effect on the response by the variation of inter-administration interval in slow-growing tumors and fast, so as the radiosensitive and radioresistant tumors. You can set conditions irradiation to an acceptable level of thrombocytopenia (onset and duration of the minimum in the curve) and renal irradiation below the limit of tolerance. It is possible to design experiments evaluation of therapeutic radiopharmaceuticals with a greater degree of refinement. (author)

The crucial role that endogenously produced IFN-β plays in eliciting an immune response against cancer has recently started to be elucidated. Endogenous IFN-β has an important role in immune surveillance and control of tumor development. Accordingly, the role of TLR agonists as cancer therapeutic agents is being revisited via the strategy of intra/peritumoral injection with the idea of stimulating the production of endogenous type I IFN inside the tumor. Polyadenylic-polyuridylic acid (poly A:U) is a dsRNA mimetic explored empirically in cancer immunotherapy a long time ago with little knowledge regarding its mechanisms of action. In this work, we have in vivo visualized the IFN-β required for the antitumor immune response elicited in a therapeutic model of poly A:U administration. In this study, we have identified the role of host type I IFNs, cell populations that are sources of IFN-β in the tumor microenvironment, and other host requirements for tumor control in this model. One single peritumoral dose of poly A:U was sufficient to induce IFN-β, readily visualized in vivo. IFN-β production relied mainly on the activation of the transcription factor IFN regulatory factor 3 and the molecule UNC93B1, indicating that TLR3 is required for recognizing poly A:U. CD11c(+) cells were an important, but not the only source of IFN-β. Host type I IFN signaling was absolutely required for the reduced tumor growth, prolonged mice survival, and the strong antitumor-specific immune response elicited upon poly A:U administration. These findings add new perspectives to the use of IFN-β-inducing compounds in tumor therapy. Copyright © 2016 by The American Association of Immunologists, Inc.

Is Forced Swimming Immobility a Good Endpoint for Modeling Negative Symptoms of Schizophrenia? - Study of Sub-Anesthetic Ketamine Repeated Administration Effects

Directory of Open Access Journals (Sweden)

GILDA NEVES

2017-08-01

Full Text Available ABSTRACT Immobility time in the forced swimming has been described as analogous to emotional blunting or apathy and has been used for characterizing schizophrenia animal models. Several clinical studies support the use of NMDA receptor antagonists to model schizophrenia in rodents. Some works describe the effects of ketamine on immobility behavior but there is variability in the experimental design used leading to controversial results. In this study, we evaluated the effects of repeated administration of ketamine sub-anesthetic doses in forced swimming, locomotion in response to novelty and novel object recognition, aiming a broader evaluation of the usefulness of this experimental approach for modeling schizophrenia in mice. Ketamine (30 mg/kg/day i.p. for 14 days induced a not persistent decrease in immobility time, detected 24h but not 72h after treatment. This same administration protocol induced a deficit in novel object recognition. No change was observed in mice locomotion. Our results confirm that repeated administration of sub-anesthetic doses of ketamine is useful in modeling schizophrenia-related behavioral changes in mice. However, the immobility time during forced swimming does not seem to be a good endpoint to evaluate the modeling of negative symptoms in NMDAR antagonist animal models of schizophrenia.

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

[Near-Drowning with Good Outcome after ECMO-Therapy and Therapeutic Hypothermia Despite 20 Minutes of Anoxia and 16 Hours of Hypoxia].

Introduction  Drowning with submersion over 10 minutes is associated with a high mortality. Here, we present a case, in which a good neurological outcome was achieved after interdisciplinary, intensive care therapy despite submersion of 20 minutes followed by 16 hours of hypoxia. History  A 19 year old man drowned in fresh-water. After 20 minutes submersion he was localized and salvaged from 8 meters depth and primarily resuscitated successfully after 10 minutes. Within the next hour, there condition worsened by respiratory deterioration due to a massive capillary leak syndrome in addition to a disseminated intravascular coagulation. Treatment  This made implantation of a veno-venous ECMO (extracorporeal membrane oxygenation) therapy necessary. Despite intensive care medicine including extracorporeal therapy a sufficient oxygenation (arterial pO 2 > 60 mmHg) was reached only 16 hours after the drowning. Clinical Course  During this time the patient was treated with a mild therapeutic hypothermia for cerebral protection. Despite the prolonged hypoxia, ECMO could be removed five days after the drowning and the patient was extubated after another five days without significant neurological deficits. Conclusion  Despite submersion of 20 minutes followed by prolonged hypoxia, a good neurological outcome could be achieved in our patient. This case suggests, that tolerance of hypoxia is possibly underestimated after drowning. © Georg Thieme Verlag KG Stuttgart · New York.

PYTHIOSIS: A THERAPEUTIC APPROACH

Directory of Open Access Journals (Sweden)

C. M. C. Falcão

2015-10-01

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

Full Text Available Chronotherapy involves the administration of medication in coordination with the body’s circadian rhythms to maximise therapeutic effectiveness and minimise/avoid adverse effects. The aim of this study is to investigate the “time of administration” recommendations on chronotherapy for commonly-prescribed medicines in Australia. This study also aimed to explore the quality of information on the timing of administration presented in drug information sources, such as consumer medicine information (CMI and approved product information (PI. Databases were searched for original research studies reporting on the impact of “time of administration” of the 30 most commonly-prescribed medicines in Australia for 2014. Further, time of administration recommendations from drug information sources were compared to the evidence from chronotherapy trials. Our search revealed 27 research studies, matching the inclusion and exclusion criteria. In 56% (n = 15 of the research studies, the therapeutic effect of the medicine varied with the time of administration, i.e., supported chronotherapy. For some medicines (e.g., simvastatin, circadian-based optimal administration time was evident in the information sources. Overall, dedicated studies on the timing of administration of medicines are sparse, and more studies are required. As it stands, information provision to consumers and health professionals about the optimal “time” to take medications lags behind emerging evidence.

GOOD GOVERNANCE AND TRANSFORMATION

Directory of Open Access Journals (Sweden)

Hans-Jürgen WAGENER

2005-12-01

Full Text Available Transformation of a totalitarian, basically administratively coordinated system into a democratic one that is coordinated predominantly by markets and competition has been triggered by, among others, the perception of a serious deficit in welfare and happiness. Public policy has a special task transforming the economic order by liberalisation, privatisation, stabilisation and the installation of institutions that are supportive for competition. After 15 years since transformation began, there are sufficiently differentiated success stories to test the hypothesis: it was good governance that is responsible for success and bad governance for failure. The empirical results support the “Lorenzetti hypothesis”: where freedom, security and trust prevail, the economy flourishes, where they are lacking, the costs of long-term investment are too high. The initial conditions of transition countries seem to be quite similar, nevertheless, even there one can discern good and bad governance. The extent of socialist lawfulness, planning security, cronyism and corruption differed widely between East Berlin and Tashkent. And a good deal of such variations can be found in the pre-socialist history of these countries. However, the main conclusion is that the co-evolution hypothesis states that both, welfare and good governance, go together.

The results showed that illegal cannavaping would be subjected to marginal development due to the poor solubility of BHO in commercial liquid refills (especially those with high glycerin content). This prevents the manufacture of liquid refills with high BHO concentrations adopted by most recreational users of cannabis to feel the psychoactive effects more rapidly and extensively. Conversely, “therapeutic cannavaping” could be an efficient route for cannabinoids administration because less concentrated cannabinoids-enriched liquid refills are required. However, the electronic device marketed for therapeutic cannavaping should be carefully designed to minimize potential overheating and contaminant generation. PMID:27228348

Bacteria entering the bloodstream via translocation from the gastrointestinal tract spread hematogenously and can trigger bacterial chondronecrosis with osteomyelitis (BCO) by infecting osteochondrotic microfractures in the epiphyseal-physeal cartilage of the proximal femora and tibiae. In experiment 1, broilers were fed control feed or the same feed containing BacPack 2X, which includes the prebiotic IMW50 (a mannan oligosaccharide beta-glucan yeast cell wall product) plus the probiotic Calsporin (Bacillus subtilis C-3102). Broilers reared on wire flooring consistently developed higher incidences of BCO than hatchmates reared on wood shavings litter (≥24 vs. ≤4%, respectively; P=0.001). Adding BacPack 2X to the feed on d 1 through 56 delayed the age of onset and reduced the cumulative incidence of BCO on wire flooring when compared with broilers fed the control feed (24.0 vs. 40.7%, respectively; P=0.003). In experiment 2, broilers reared on wire flooring received tap water on d 1 through 62 (control group) or therapeutic levels of the potent fluoroquinolone antimicrobial enrofloxacin in the water on d 35 through 54 (enrofloxacin group). During enrofloxacin administration, half as many birds developed BCO in the enrofloxacin group when compared with the control group (8.1 vs. 19.5%, respectively, on d 35 through 54; P=0.001), whereas both groups had similar BCO incidences subsequent to withdrawing enrofloxacin on d 55 through 62 (14.8 vs. 18.2% for the enrofloxacin vs. control groups; P=0.386). Cumulative lameness incidences for d 1 through 62 were higher for the control group than for the enrofloxacin group (39.0 vs. 25.8%, respectively; P=0.003). These results demonstrate that wire flooring imposes a rigorous challenge that leads to high incidences of BCO that can be difficult to suppress, even with therapeutic doses of enrofloxacin. Prophylactically adding BacPack 2X to the feed reduced the incidence of BCO lameness by a proportion similar to that achieved

The development of new non-invasive diagnostic and therapeutic approaches is of paramount importance in order to improve the outcome of patients with glioblastoma (GBM). In this work we investigated a completely non-invasive pre-clinical protocol to effectively target and detect brain tumors through the orotracheal route, using ultra-small nanoparticles (USRPs) and MRI. A mouse model of GBM was developed. In vivo MRI acquisitions were performed before and after intravenous or orotracheal administration of the nanoparticles to identify and segment the tumor. The accumulation of the nanoparticles in neoplastic lesions was assessed ex vivo through fluorescence microscopy. Before the administration of contrast agents, MR images allowed the identification of the presence of abnormal brain tissue in 73% of animals. After orotracheal or intravenous administration of USRPs, in all the mice an excellent co-localization of the position of the tumor with MRI and histology was observed. The elimination time of the USRPs from the tumor after the orotracheal administration was approximately 70% longer compared with intravenous injection. MRI and USRPs were shown to be powerful imaging tools able to detect, quantify and longitudinally monitor the development of GBMs. The absence of ionizing radiation and high resolution of MRI, along with the complete non-invasiveness and good reproducibility of the proposed protocol, make this technique potentially translatable to humans. To our knowledge, this is the first time that the advantages of a needle-free orotracheal administration route have been demonstrated for the investigation of the pathomorphological changes due to GBMs. Copyright © 2015 John Wiley & Sons, Ltd.

Intrathecal delivery of protein therapeutics to the brain: a critical reassessment.

2014-11-01

Disorders of the central nervous system (CNS), including stroke, neurodegenerative diseases, and brain tumors, are the world's leading causes of disability. Delivery of drugs to the CNS is complicated by the blood-brain barriers that protect the brain from the unregulated leakage and entry of substances, including proteins, from the blood. Yet proteins represent one of the most promising classes of therapeutics for the treatment of CNS diseases. Many strategies for overcoming these obstacles are in development, but the relatively straightforward approach of bypassing these barriers through direct intrathecal administration has been largely overlooked. Originally discounted because of its lack of usefulness for delivering small, lipid-soluble drugs to the brain, the intrathecal route has emerged as a useful, in some cases perhaps the ideal, route of administration for certain therapeutic protein and targeted disease combinations. Here, we review blood-brain barrier functions and cerebrospinal fluid dynamics and their relevance to drug delivery via the intrathecal route, discuss animal and human studies that have investigated intrathecal delivery of protein therapeutics, and outline several characteristics of protein therapeutics that can allow them to be successfully delivered intrathecally.

Full Text Available Joko Widodo (Jokowi is a leader that is widely expected to transform Indonesia into a better country. Hopes and wishes were rising when he was elected as the president of Indonesia. This paper will describe various innovations undertaken before and after his presidential inauguration as well as the assorted innovations made in reforming the administration of his cabinet. As the president of Indonesia, Joko Widodo is required to realize the aspirations of the people in freeing the government from corruption, collusion, and nepotism. The management of ministerial and non-ministerial institutions becomes the very first crucial issue undertaken by Joko Widodo. This led to a polemic in regards to reducing or increasing the number of institutions, as the Jokowi administration actually increased the amount. In Susilo Bambang Yudhoyono's administration, several policies were made systematically and based on legislations that had been approved by the lagislature. Joko Widodo's administration in more partial in nature. The administrative reform program that is highly anticipated is the continuation of the Public Service Act. This law is a step forward from the administrative reform program that aims at the creation of good governance. Changes is career path, salary system, pension and benefits for civil servants, performance-based staffing are various efforts of sustainability carried out by Joko Widodo's administration.

Purpose/Objective: The nucleoside analogue gemcitabine inhibits cellular repair and repopulation, induces apoptosis, causes tumor growth delay, and enhances radiation-induced growth delay. After single doses of drug and radiation, maximum enhancement of tumor response was obtained when gemcitabine preceded radiation by at least 24 h. Conversely, the cellular radioresponse of the normal gastrointestinal epithelium was slightly protected when gemcitabine and radiation were separated by 24 h. This differential response created a time frame within which therapeutic gain could be maximized. In our present investigation, we sought to define the most therapeutically beneficial scheme of gemcitabine administration when combined with fractionated radiotherapy. Methods and Materials: C3Hf/Kam mice were given identical drug and radiation schedules of administration, and both normal tissue (jejunal mucosa) and tumor (Sa-NH) responses were measured. Irradiation was given once per day for 5 days in normal tissue and tumor growth delay studies and twice per day for the tumor cure endpoint. A total dose of 25 mg/kg gemcitabine was given i.p. in 1 of 3 schedules: a single dose of 25 mg/kg 24 h before the start of fractionated irradiation, 12.5 mg/kg 24 h before the first and third radiation doses, or 24 h before each of 5 radiation doses. Groups of mice bearing 7- or 8-mm diameter tumors were treated with gemcitabine alone or in combination with fractionated irradiation under ambient or hypoxic conditions. The survival response of the jejunal mucosa was quantified by the microcolony assay and histologically by quantifying apoptosis, mitosis, S-phase fraction, and crypt cellularity. Results: For tumor growth delay, dose-modifying factors (DMFs) were similar (1.34-1.46) for all 3 schedules of drug administration. In contrast, the response of the jejunum was strongly dependent on the schedule of gemcitabine administration. A single dose of gemcitabine before the start of fractionated

Oral tolerance is defined as the specific suppression of humoral and/or cellular immune responses to an antigen by administration of the same antigen through the oral route. Due to its absence of toxicity, easy administration, and antigen specificity, oral tolerance is a very attractive approach to prevent unwanted immune responses that cause a variety of diseases or that complicate treatment of a disease. Many researchers have induced oral tolerance to efficiently treat autoimmune and inflammatory diseases in different animal models. However, clinical trials yielded limited success. Thus, understanding the mechanisms of oral tolerance induction to therapeutic proteins is critical for paving the way for clinical development of oral tolerance protocols. This review will summarize progress on understanding the major underlying tolerance mechanisms and contributors, including antigen presenting cells, regulatory T cells, cytokines, and signaling pathways. Potential applications, examples for therapeutic proteins and disease targets, and recent developments in delivery methods are discussed. Copyright © 2012 Elsevier B.V. All rights reserved.

Recent technological advances in the generation, characterization, and bioprocessing of human pluripotent stem cells (hPSCs) have created new hope for their use as a source for production of cell-based therapeutic products. To date, a few clinical trials that have used therapeutic cells derived from hESCs have been approved by the Food and Drug Administration (FDA), but numerous new hPSC-based cell therapy products are under various stages of development in cell therapy-specialized companies and their future market is estimated to be very promising. However, the multitude of critical challenges regarding different aspects of hPSC-based therapeutic product manufacturing and their therapies have made progress for the introduction of new products and clinical applications very slow. These challenges include scientific, technological, clinical, policy, and financial aspects. The technological aspects of manufacturing hPSC-based therapeutic products for allogeneic and autologous cell therapies according to good manufacturing practice (cGMP) quality requirements is one of the most important challenging and emerging topics in the development of new hPSCs for clinical use. In this review, we describe main critical challenges and highlight a series of technological advances in all aspects of hPSC-based therapeutic product manufacturing including clinical grade cell line development, large-scale banking, upstream processing, downstream processing, and quality assessment of final cell therapeutic products that have brought hPSCs closer to clinical application and commercial cGMP manufacturing. © 2013.

Gonzalez-Rey, Elena; Chorny, Alejo; Delgado, Mario

2006-05-01

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

The optimal sequencing and integration of radiopharmaceutical therapy with respect to the multiple and competing therapeutic modalities is examined. It is estimated that the central goal of therapeutic nuclear medicine is to increase radiopharmaceutical delivery to tumour targets while sparing sensitive normal tissues. Among the factors to be considered in the choice of therapeutic radionuclides are: the decay mode, gamma-ray yield, half-lives and chemical reactivity. Several routes of administration are discussed and a number of manipulations which may be used to further improve radioparmaceutical delivery are outlined. The difficulty to perform accurate radiation dosimetry is also briefly examined. 14 refs., 1 tab

2018-01-01

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

2017-10-01

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

Reversal of renal dysfunction by targeted administration of VEGF into the stenotic kidney: a novel potential therapeutic approach.

Science.gov (United States)

Chade, Alejandro R; Kelsen, Silvia

2012-05-15

Renal microvascular (MV) damage and loss contribute to the progression of renal injury in renovascular disease (RVD). Whether a targeted intervention in renal microcirculation could reverse renal damage is unknown. We hypothesized that intrarenal vascular endothelial growth factor (VEGF) therapy will reverse renal dysfunction and decrease renal injury in experimental RVD. Unilateral renal artery stenosis (RAS) was induced in 14 pigs, as a surrogate of chronic RVD. Six weeks later, renal blood flow (RBF) and glomerular filtration rate (GFR) were quantified in vivo in the stenotic kidney using multidetector computed tomography (CT). Then, intrarenal rhVEGF-165 or vehicle was randomly administered into the stenotic kidneys (n = 7/group), they were observed for 4 additional wk, in vivo studies were repeated, and then renal MV density was quantified by 3D micro-CT, and expression of angiogenic factors and fibrosis was determined. RBF and GFR, MV density, and renal expression of VEGF and downstream mediators such as p-ERK 1/2, Akt, and eNOS were significantly reduced after 6 and at 10 wk of untreated RAS compared with normal controls. Remarkably, administration of VEGF at 6 wk normalized RBF (from 393.6 ± 50.3 to 607.0 ± 45.33 ml/min, P < 0.05 vs. RAS) and GFR (from 43.4 ± 3.4 to 66.6 ± 10.3 ml/min, P < 0.05 vs. RAS) at 10 wk, accompanied by increased angiogenic signaling, augmented renal MV density, and attenuated renal scarring. This study shows promising therapeutic effects of a targeted renal intervention, using an established clinically relevant large-animal model of chronic RAS. It also implies that disruption of renal MV integrity and function plays a pivotal role in the progression of renal injury in the stenotic kidney. Furthermore, it shows a high level of plasticity of renal microvessels to a single-dose VEGF-targeted intervention after established renal injury, supporting promising renoprotective effects of a novel potential therapeutic intervention to

Therapeutic Vaccination for HPV Induced Cervical Cancers

Directory of Open Access Journals (Sweden)

Joeli A. Brinkman

2007-01-01

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

If at first, motivation was considered merely a formal condition of the administrative act, as a result of the national and European, doctrinal and jurisprudential evolution, motivation is now regarded as one of the most important conditions of validity for the administrative act. Motivating administrative acts represents also a manifestation of the right to information, sealed by the Romanian Constitution, and a dimension of the right to a good administration, as stipulated in the Charter of Fundamental Rights of the European Union.

Conotoxins that confer therapeutic possibilities

KAUST Repository

Essack, Magbubah

2012-06-04

Cone snails produce a distinctive repertoire of venom peptides that are used both as a defense mechanism and also to facilitate the immobilization and digestion of prey. These peptides target a wide variety of voltage- and ligand-gated ion channels, which make them an invaluable resource for studying the properties of these ion channels in normal and diseased states, as well as being a collection of compounds of potential pharmacological use in their own right. Examples include the United States Food and Drug Administration (FDA) approved pharmaceutical drug, Ziconotide (Prialt; Elan Pharmaceuticals, Inc.) that is the synthetic equivalent of the naturally occurring ?-conotoxin MVIIA, whilst several other conotoxins are currently being used as standard research tools and screened as potential therapeutic drugs in pre-clinical or clinical trials. These developments highlight the importance of driving conotoxin-related research. A PubMed query from 1 January 2007 to 31 August 2011 combined with hand-curation of the retrieved articles allowed for the collation of 98 recently identified conotoxins with therapeutic potential which are selectively discussed in this review. Protein sequence similarity analysis tentatively assigned uncharacterized conotoxins to predicted functional classes. Furthermore, conotoxin therapeutic potential for neurodegenerative disorders (NDD) was also inferred. 2012 by the authors; licensee MDPI.

THE DECISIONAL TRANSPARENCY IN PUBLIC ADMINISTRATION

Directory of Open Access Journals (Sweden)

OCTAVIA MARIA CILIBIU

2011-04-01

Full Text Available The principle of decisional transparency is one of the principles of good administration, fundamental principles of public administration and it is enshrined in the law of many European Union member states, including our country. In their work the public authorities must show transparency reflected by the active involvement of citizens in administrative decision as its primary beneficiary. The citizen information, consultation and his stimulation to participate actively in the elaboration of draft normative acts for their preparation and before that by bringing them to public knowledge, are tasks of the public authorities which exceed the limit of the obligations imposed by internal rules and are significant efforts to modernize the public administration and rallying to the administrative structures.

2007-01-01

Heat shock proteins (HSPs) play crucial roles in cellular responses to stressful conditions. Expression of HSPs in invasive or high-risk superficial bladder cancer was investigated to identify whether HSPs predict pathological response to neoadjuvant chemoradiotherapy (CRT). Immunohistochemistry was used to assess expression levels of HSP27, HSP60, HSP70, HSP90 and p53 in 54 patients with invasive or high-risk superficial bladder cancer, prior to low-dose neoadjuvant CRT, followed by radical or partial cystectomy. Patients were classified into two groups (good or poor responders) depending on pathological response to CRT, which was defined as the proportion of morphological therapeutic changes in surgical specimens. Good responders showed morphological therapeutic changes in two-thirds or more of tumor tissues. In contrast, poor responders showed changes in less than two-thirds of tumor tissues. Using a multivariate analysis, positive HSP60 expression prior to CRT was found to be marginally associated with good pathological response to CRT (P=0.0564). None of clinicopathological factors was associated with HSP60 expression level. In the good pathological responders, the 5-year cause-specific survival was 88%, which was significantly better than survival in the poor responders (51%) (P=0.0373). Positive HSP60 expression prior to CRT may predict good pathological response to low-dose neoadjuvant CRT in invasive or high-risk superficial bladder cancer. (author)

Prevention of infectious diseases in patients with Good syndrome.

Science.gov (United States)

Multani, Ashrit; Gomez, Carlos A; Montoya, José G

2018-08-01

Good syndrome is a profoundly immunocompromising condition with heterogeneous immune deficits characterized by the presence of thymoma, low-to-absent B-lymphocyte counts, hypogammaglobulinemia, and impaired cell-mediated immunity. Opportunistic infectious diseases associated with Good syndrome represent a diagnostic and therapeutic challenge, given their protean clinical manifestations. Although these infectious complications have been reviewed in prior publications, recommendations regarding their prevention have been lacking. Good syndrome usually occurs in adult patients between the ages of 40 and 70 years. Immunologically, it is characterized by low or absent peripheral blood B lymphocytes, hypogammaglobulinemia, and variable defects in cell-mediated immunity including low CD4 T counts, inverted CD4:CD8 T-lymphocyte ratio, and reduced T-lymphocyte mitogen proliferative responses. Patients with Good syndrome are susceptible to a variety of infectious diseases, of which the most common are recurrent bacterial sinopulmonary infections, mucocutaneous candidiasis, and CMV tissue-invasive disease. Preventive guidelines including targeted antimicrobial prophylaxis and vaccination strategies can mitigate infectious complications in patients with Good syndrome. Immunological deficits and infectious complications in Good syndrome have been described for over 60 years. Further research is needed to elucidate its exact pathogenesis and define the mechanistic relationship between thymoma and hypogammaglobulinemia. However, tailored prophylactic strategies can be recommended for patients with Good syndrome.

The radiopharmaceutical administration to lactating women for therapeutic or diagnostic purpose can achieve a radiological risk to the breast feeding child due to levels of radioactivity in the breast milk. International recommendations regarding safe assumption of nursing mother after radiopharmaceutical administration were analysed. We examined the formula proposed by Rommey et al. to establish objective guidelines in case of the administration of radiopharmaceutical to nursing mothers. The ICRP 54 metabolic model for iodine was modified in order to calculate the suppression breast feeding's period according to the radioactivity measured in the breast milk.

Nuclear export policy of the Reagan Administration

Energy Technology Data Exchange (ETDEWEB)

Pilat, J F; Donnelly, W H [Library of Congress, Washington, DC (USA)

1983-06-01

The Reagan Administration maintains the Carter Administration's objective of non-proliferation of nuclear weapons as being fundamental to US nuclear export policy. However, it sees the USA as having another important role to play in influencing the use of nuclear power and the trading of related goods and technologies in other countries. While the Administration believes its policies will prove beneficial to the USA, there is concern that trade considerations are being given priority over preventing the proliferation of nuclear weapons.

New therapeutic approaches for treatment of tularaemia: a review

Directory of Open Access Journals (Sweden)

Sandrine eBOISSET

2014-03-01

Full Text Available Antibiotic treatment of tularaemia is based on a few drugs, including the fluoroquinolones, the tetracyclines and the aminoglycosides. Because no effective and safe vaccine is currently available, tularaemia prophylaxis following proven exposure to F. tularensis also relies on administration of antibiotics. A number of reasons make it necessary to search for new therapeutic alternatives: the potential toxicity of first-line drugs, especially in children and pregnant women; a high rate of treatment relapses and failures, especially for severe and/or suppurated forms of the disease; and the possible use of antibiotic-resistant strains in the context of a biological threat. This review presents novel therapeutic approaches that have been explored in recent years to improve tularaemia patients’ management and prognosis. First, the activities of newly available antibiotic compounds were evaluated against F. tularensis, including tigecycline (a glycylcycline, ketolides (telithromycin and cethromycin and fluoroquinolones (moxifloxacin, gatifloxacin, trovafloxacin and grepafloxacin. The liposome delivery of some antibiotics was evaluated. The effect of antimicrobial peptides against F. tularensis was also considered. Other drugs were evaluated for their ability to suppress the intracellular multiplication of F. tularensis. The effects of the modulation of the innate immune response (especially via TLR receptors on the course of F. tularensis infection were characterized. Another approach was the administration of specific antibodies to induce passive resistance to F. tularensis infection. All of these studies highlight the need to develop new therapeutic strategies to improve the management of patients with tularaemia. Many possibilities exist, some unexplored. Moreover, it is likely that new therapeutic alternatives that are effective against this intracellular pathogen could be, at least partially, extrapolated to other human pathogens.

Predictive value of tracer studies for 131I treatment in hyperthyroid cats

International Nuclear Information System (INIS)

Broome, M.R.; Turrel, J.M.; Hays, M.T.

1988-01-01

In 76 cats with hyperthyroidism, peak thyroidal radioiodine ( 131 I) uptakes and effective half-lives were determined after administration of tracer and therapeutic activities of 131 I. In 6 additional hyperthyroid cats, only peak thyroidal uptakes after administration of tracer and therapeutic activities of 131 I were determined. Good correlation was found between peak thyroidal uptakes of tracer and therapeutic 131 I; however, only fair correlation was observed between effective half-lives. In 79% of the cats, the effective half-life for therapeutic 131 I was longer than that for tracer 131 I. After administration of therapeutic activity of 131 I, monoexponential and biphasic decay curves were observed in 51 and 16 cats, respectively. Using therapeutic kinetic data, radiation doses to the thyroid gland were calculated retrospectively on the basis of 2 methods for determining the activity of 131 I administered: (1) actual administration of tracer-compensated activity and (2) hypothetic administration of uniform activity (3 mCi). Because of the good predictive ability of tracer kinetic data for the therapeutic kinetic data, the tracer-compensated radiation doses came significantly (P = 0.008) closer to the therapeutic goal than did the uniform-activity doses. In addition, the use of tracer kinetic information reduced the extent of the tendency for consistently high uniform-activity doses. A manual method for acquiring tracer kinetic data was developed and was an acceptable alternative to computerized techniques. Adoption of this method gives individuals and institutions with limited finances the opportunity to characterize the iodine kinetics in cats before proceeding with administration of therapeutic activities of 131 I

Therapeutic Options in Idiopathic Burning Mouth Syndrome: Literature Review

Science.gov (United States)

Miziara, Ivan; Chagury, Azis; Vargas, Camila; Freitas, Ludmila; Mahmoud, Ali

2014-01-01

Introduction Burning mouth syndrome (BMS) is characterized by a burning sensation in the tongue, palate, lips, or gums of no well-defined etiology. The diagnosis and treatment for primary BMS are controversial. No specific laboratory tests or diagnostic criteria are well established, and the diagnosis is made by excluding all other possible disorders. Objective To review the literature on the main treatment options in idiopathic BMS and compare the best results of the main studies in 15 years. Data Synthesis We conducted a literature review on PubMed/MEDLINE, SciELO, and Cochrane-BIREME of work in the past 15 years, and only selected studies comparing different therapeutic options in idiopathic BMS, with preference for randomized and double-blind controlled studies. Final Comments Topical clonazepam showed good short-term results for the relief of pain, although this was not presented as a definitive cure. Similarly, α-lipoic acid showed good results, but there are few randomized controlled studies that showed the long-term results and complete remission of symptoms. On the other hand, cognitive therapy is reported as a good and lasting therapeutic option with the advantage of not having side effects, and it can be combined with pharmacologic therapy.

Ischemia and reperfusion represent major mechanisms of tissue injury and organ failure. The timing of administration and the duration of action limit current treatment approaches using pharmacological agents. In this study, we have successfully developed a preemptive strategy for tissue protection using an adenoassociated vector system containing erythropoietin hypoxia response elements for ischemia-regulated expression of the therapeutic gene human heme-oxygenase-1 (hHO-1). We demonstrate that a single administration of this vector several weeks in advance of ischemia/reperfusion injury to multiple tissues such as heart, liver, and skeletal muscle yields rapid and timely induction of hHO-1 during ischemia that resulted in dramatic reduction in tissue damage. In addition, overexpression of therapeutic transgene prevented long-term pathological tissue remodeling and normalized tissue function. Application of this regulatable system using an endogenous physiological stimulus for expression of a therapeutic gene may be a feasible strategy for protecting tissues at risk of ischemia/reperfusion injury.

ROCK as a therapeutic target for ischemic stroke.

Science.gov (United States)

Sladojevic, Nikola; Yu, Brian; Liao, James K

2017-12-01

Stroke is a major cause of disability and the fifth leading cause of death. Currently, the only approved acute medical treatment of ischemic stroke is tissue plasminogen activator (tPA), but its effectiveness is greatly predicated upon early administration of the drug. There is, therefore, an urgent need to find new therapeutic options for acute stroke. Areas covered: In this review, we summarize the role of Rho-associated coiled-coil containing kinase (ROCK) and its potential as a therapeutic target in stroke pathophysiology. ROCK is a major regulator of cell contractility, motility, and proliferation. Many of these ROCK-mediated processes in endothelial cells, vascular smooth muscle cells, pericytes, astrocytes, glia, neurons, leukocytes, and platelets are important in stroke pathophysiology, and the inhibition of such processes could improve stroke outcome. Expert commentary: ROCK is a potential therapeutic target for cardiovascular disease and ROCK inhibitors have already been approved for human use in Japan and China for the treatment of acute stroke. Further studies are needed to determine the role of ROCK isoforms in the pathophysiology of cerebral ischemia and whether there are further therapeutic benefits with selective ROCK inhibitors.

Environment is important in human life. Conflict of interest comes between development of economy sector, citizenship needs and Governance, as it becomes completely difficult to analyze. The environment's lawsuit is increase from the beginning of the Court established. The duty of Administrative Court are to investigate, decide and settle administrative disputes. The Governance has to pay attention before issuing the Government's decree by put principle of good governance as priority. The issue in this paper is strengthening the role of Administrative Court to maintain the environment reuse by settle environment disputes based on the importance of environment. The administrative decisions in environment field may cause a loss or damage for the people. When the public officer did not put the appreciation to the reuse of environment and principle of good governance, it will become problems. The decision should be environmentally friendly. There should be certified judge to settle the dispute. The method of this research by examines the Judge's verdict in environment disputes, and its relation with regulations and the newest issues. The conclusion is increase the role of the Administrative Court to maintain the environment by law enforcement through settle environment disputes.

Kristen, G; Schaefer, A; von Schlichtegroll, A

1986-06-01

Fenetylline (CAPTAGON) is included in a list of compounds to be considered by a World Health Organization (WHO) Expert Committee in April 1985 for possible international scheduling under the Convention on Psychotropic Substances, 1971. For over 23 years, this central stimulant has been used therapeutically in hyperkinetic children and other indications in place of amphetamines and other central stimulants with higher risk levels. In good correspondence with recent animal data fenetylline also shows significant qualitative and quantitative differences compared to amphetamine in man. It has few adverse side effects, a lower abuse potential and little actual abuse compared to amphetamine. Thus its benefit/risk assessment is substantially more favourable than that of other central stimulants. For proper therapeutic use of the substance, prescription status is or should be required by national authorities.

Alsaeed, D; Furniss, D; Blandford, A; Smith, F; Orlu, M

2018-06-01

The use of enteral tube feeding at home is becoming more widespread, with patients ranging in age and diseases. Dysphagia and swallowing difficulties can compromise nutritional intake and the administration of oral medications, affecting therapeutic outcomes negatively. Carers' experiences of medicines administration and medicines optimization have not been explored fully. The objectives of this study were to identify issues carers experience in medicines administration; the strategies they have developed to cope; and suggestions to improve the medicines administration process. An online survey was promoted nationally; 42 carers completed it. Descriptive statistical analysis was applied, as well as thematic analysis of open-ended responses. Results were compared against the 4 principles of medicines optimization. 93% of respondents administered medications with enteral feeding tubes, but only 62% had received advice from healthcare professionals and only 8% had received written information on how to do so. Responses identified 5 medicines administration issues experienced by carers; 4 strategies they developed to cope; and 3 main areas of suggestions to improve medicines administration via enteral feeding at home. The 4 principles of medicines optimization have not previously been applied to enteral feeding. We present a novel account of carers' experiences, for example coping with ill-suited formulations and a lack of training and support, which should inform better practice (Principle 1). Carers sometimes experience suboptimal choice of medicines (Principle 2). Carers' practices are not always well-informed and may affect therapeutic outcomes and safety (Principle 3). There is scope for improvement in carer training, education and support to better support medicines optimization (Principle 4). © 2018 The Authors.

to verify whether the Paw Edema Model can be used in investigations about the effects of Therapeutic Touch on inflammation by measuring the variables pain, edema and neutrophil migration. this is a pilot and experimental study, involving ten male mice of the same genetic strain and divided into experimental and control group, submitted to the chemical induction of local inflammation in the right back paw. The experimental group received a daily administration of Therapeutic Touch for 15 minutes during three days. the data showed statistically significant differences in the nociceptive threshold and in the paw circumference of the animals from the experimental group on the second day of the experiment. the experiment model involving animals can contribute to study the effects of Therapeutic Touch on inflammation, and adjustments are suggested in the treatment duration, number of sessions and experiment duration.

Negative Allosteric Modulators of Metabotropic Glutamate Receptors Subtype 5 in Addiction: a Therapeutic Window

Science.gov (United States)

2016-01-01

Background: Abundant evidence at the anatomical, electrophysiological, and molecular levels implicates metabotropic glutamate receptor subtype 5 (mGluR5) in addiction. Consistently, the effects of a wide range of doses of different mGluR5 negative allosteric modulators (NAMs) have been tested in various animal models of addiction. Here, these studies were subjected to a systematic review to find out if mGluR5 NAMs have a therapeutic potential that can be translated to the clinic. Methods: Literature on consumption/self-administration and reinstatement of drug seeking as outcomes of interest published up to April 2015 was retrieved via PubMed. The review focused on the effects of systemic (i.p., i.v., s.c.) administration of the mGluR5 NAMs 3-((2-Methyl-4-thiazolyl)ethynyl)pyridine (MTEP) and 2-Methyl-6-(phenylethynyl)pyridine (MPEP) on paradigms with cocaine, ethanol, nicotine, and food in rats. Results: MTEP and MPEP were found to reduce self-administration of cocaine, ethanol, and nicotine at doses ≥1mg/kg and 2.5mg/kg, respectively. Dose-response relationship resembled a sigmoidal curve, with low doses not reaching statistical significance and high doses reliably inhibiting self-administration of drugs of abuse. Importantly, self-administration of cocaine, ethanol, and nicotine, but not food, was reduced by MTEP and MPEP in the dose range of 1 to 2mg/kg and 2.5 to 3.2mg/kg, respectively. This dose range corresponds to approximately 50% to 80% mGluR5 occupancy. Interestingly, the limited data found in mice and monkeys showed a similar therapeutic window. Conclusion: Altogether, this review suggests a therapeutic window for mGluR5 NAMs that can be translated to the treatment of substance-related and addictive disorders. PMID:26802568

2016-06-01

Full Text Available The benefit of the study is to highlight the issues of the administrative (municipal services by Ukrainian public authorities as a priority of the on-going decentralization and administrative reforms in Ukraine. Consequently, provision of the high quality services to the citizens became a main mission of all public authorities (State bodies, regional authorities, local self-government bodies in the framework of the implementation of the new public management and good governance standards on all levels – national, regional and local. It reflects also the main European tendencies in the field of public administration reform which are fixed in the documents of the international organizations (Council of Europe, European Union, OECD/ SIGMA etc.. For example, the European Strategy on Innovation and Good Governance on Local Level which was adopted by the Council of Europe Committee of Ministers in 2008 fixed the principle of the ability to provide high quality services to the citizens as one of its twelve main principles of good governance on local level. This study tested the key issues of increasing the quality of the services which are provided to the citizens by the State bodies and the local self-government bodies. Moreover the study pointed out the main tendencies in the realization of the State policy in the field of the improvement of the quality of the administrative (municipal services (in the context of the on-going large-scaled decentralization reform in Ukraine as well as the main direction for its further modernization. The questions concerning the quality standards in the activity of the State bodies and LSG bodies are highlighted in order to increase the quality of the services to be provided to the citizens. Besides, the study emphasized the issues related to ensuring the transparency of the activity of the State bodies as well as the regional and the local authorities, in the field of the provision of the administrative (municipal

To elucidate the prognostic role of post-therapeutic {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography (PET), we conducted a retrospective cohort study analysing the clinical factors that affect overall survival after non-operative therapy for unresectable hepatocellular carcinoma (HCC). Sixty-seven cases with unresectable HCC who received non-operative therapy (transcatheter arterial chemoembolization: n=24, transcatheter arterial infusion chemotherapy: n=31, radiofrequency ablation: n = 5 or systemic chemotherapy: n = 7) and had received FDG PET for the evaluation of the therapeutic effect within 1 month after the end of the therapy were evaluated. Overall survival rate was evaluated using the univariate and multivariate analyses of relevant clinical and laboratory parameters before and after therapy, including visual PET analysis and quantitative analysis using maximum standardized uptake value (SUV). Visual PET diagnosis of post-therapeutic lesions was a good predictor of overall survival of unresectable HCC patients. The low FDG group showed significantly longer survival (average: 608 days) than that (average: 328 days) of the high FDG group (p<0.0001). Multivariate analysis showed four significant prognostic factors for the survival: post-therapeutic alpha-fetoprotein ({alpha}FP) level (=400 ng/ml, p=0.004), post-therapeutic visual PET diagnosis (p=0.006), post-therapeutic clinical stage (UICC stage IV, p=0.04) and post-therapeutic Milan criteria (p=0.03), while pre-therapeutic clinical factors, SUV by post-therapeutic FDG PET (5.0 or more) or others did not show significance. The present study suggests that post-therapeutic PET performed within 1 month after non-operative therapy can be a good predictor of overall survival in unresectable HCC patients, while pre-therapeutic evaluation including PET, tumour markers and clinical staging may not be useful.

Pilat, J.F.; Donnelly, W.H.

1983-01-01

tThe Reagan Administration maintains the Carter Administration's objective of non-proliferation of nuclear weapons as being fundamental to US nuclear export policy. However, it sees the USA as having another important role to play in influencing the use of nuclear power and the trading of related goods and technologies in other countries. While the Administration believes its policies will prove beneficial to the USA, there is concern that trade considerations are being given priority over preventing the proliferation of nuclear weapons.

ADMINISTRATIVE JUSTICE IN FRANCE. BETWEEN SINGULARITY AND CLASSICISM

Directory of Open Access Journals (Sweden)

H. Flavier

2016-01-01

Full Text Available The administrative justice in France oscillates between classicism and singularity. Multiple factors explain how administrative justice has come to occupy a particular place in French administrative law. Administrative justice has not only settled disputes between administration and private persons, but as well, built the French administrative law. One of the main tasks during 19th and 20th century consisted in strengthen the independence from the executive branch and the efficiency in order to satisfy the idea of good justice. Many reforms have been led since the 1990’s. That is why we propose to depict the French system and evaluate the activity of French administrative justice concerning the judicial organization, its jurisdiction and the remedies before the administrative judge. We will enlighten also our paper with a comparative approach and some statistical elements.

Full Text Available In a clinical setting, where multiple administrations of the therapeutic agent are usually required to improve the therapeutic outcome, it is crucial to assess the immunogenicity of the administered nanoparticles. In this data work, we investigated the safety profile of the repeated intravenous administration of brain-targeted stable nucleic acid lipid particles (RVG-9r-targeted SNALPs. To evaluate local activation of the immune system, we performed analysis of mouse tissue homogenates and sections from cerebellum. To investigate peripheral activation of the immune system, we used serum of mice that were intravenously injected with RVG-9r-targeted SNALPs. These data are related and were discussed in the accompanying research article entitled “Intravenous administration of brain-targeted stable nucleic acid lipid particles alleviates Machado–Joseph disease neurological phenotype” (Conceição et al., in press [1].

An Approach to Optimise Therapeutic Vancomycin Dosage in a Haemodialysis Population

LENUS (Irish Health Repository)

Gunning, H

2016-10-01

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

Endogenous and Synthetic Cannabinoids as Therapeutics in Retinal Disease

Directory of Open Access Journals (Sweden)

Despina Kokona

2016-01-01

Full Text Available The functional significance of cannabinoids in ocular physiology and disease has been reported some decades ago. In the early 1970s, subjects who smoked Cannabis sativa developed lower intraocular pressure (IOP. This led to the isolation of phytocannabinoids from this plant and the study of their therapeutic effects in glaucoma. The main treatment of this disease to date involves the administration of drugs mediating either the decrease of aqueous humour synthesis or the increase of its outflow and thus reduces IOP. However, the reduction of IOP is not sufficient to prevent visual field loss. Retinal diseases, such as glaucoma and diabetic retinopathy, have been defined as neurodegenerative diseases and characterized by ischemia-induced excitotoxicity and loss of retinal neurons. Therefore, new therapeutic strategies must be applied in order to target retinal cell death, reduction of visual acuity, and blindness. The aim of the present review is to address the neuroprotective and therapeutic potential of cannabinoids in retinal disease.

Effect of Some Therapeutic Agents on the Radionuclides Excretion from Internally Contaminated Rats

International Nuclear Information System (INIS)

Aziz, M.; Mangood, Sh.A.; Sohsah, M.A.

2009-01-01

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

Trujillo, J.; Krinsky, S.; Wilson, B.; Teague, E.

1982-01-01

A new, closed-system method to reduce air-, direct-, and incidental-contamination during therapeutic administration of oral I-131 was experimentally evaluated on twelve patients. We studied a standard control population using the routine practice of drinking the solution through a straw and compared results with our new technique. Various measurements were performed throughout all phases of dose administration to assess the relative difference of the two approaches. Using the closed system method before and during iodine administration revealed between 100 and 1000 times less activity per millimeter of air sample; whereas, the direct radiation exposure values were higher for the control population. Both the experimental and control methods had similar levels of incidental contamination

2016-07-01

Improved understanding of glomerular disease mechanisms over the past decade has led to the emergence of new and targeted therapeutic strategies for chronic kidney disease (CKD). Most promising among these are the administration of recombinant mutated human angiopoietin-like 4, sialic acid-related sugars that induce sialylation in vivo, compounds related to Bis-T-23, and immune depletion of the soluble urokinase receptor from the circulation. Taking these therapeutic strategies into clinical trials will be the first step away from repurposed and relatively toxic drugs currently used for treating kidney disease.

[Creating a reliable therapeutic relationship with the patient].

Science.gov (United States)

Matsuki, Kunihiro

2012-01-01

The factors necessary to create a reliable therapeutic relationship are presented in this paper. They include a demeanor and calmness of temperament as a psychiatric professional, a feeling of respect for the patient that is based on our common sense as human beings, an attitude of listening attentively to what the patient is revealing, maintaining an attitude of receptive neutrality, the ability to withstand the emotional burdens imposed on one by the patient, patience with any difficulty on one's own part to understand the patient, the ability to communicate clearly, including on the patient's negative aspects, and the ability to end psychiatric consultation sessions in a friendly and intimate manner. Creating a beneficial therapeutic relationship is about the building of a trusting relationship, in which the patient can constructively endure being questioned by us, or cope with the tough burdens we may place on them. However, a reliable relationship such as this contains paradoxes. Patients are able to talk to us about their suspicions, anxieties, dissatisfactions or anger only if the therapeutic relationship is good or based on trust. In other words, just like our patients, psychiatrists, too, must deal with what that the patient brings and directs toward us. It is at this point that what we call a true therapeutic relationship starts.

Measurements of iodine uptake in thyroid after diagnostic administration of 131I

Osko, J.; Pliszczynski, T.

2003-01-01

The measurements performed up to now, showed that the spectrometric measurements can be useful in selection of the patients who need special consideration during the 131 I diagnostics and treatment. The next step of the work will include the measurements of the real activity of 131 I in thyroid gland, after the therapeutic administration of radioiodine. A special collimator was designed for this purpose and the thyroid counter was calibrated using a phantom with inserts simulating different shapes of pathologically changed thyroid glands. It can be expected that the improvement of accuracy of the diagnostic measurements and better control of real activity of 131 I in thyroid gland after the therapeutic administration will contribute to the process of optimisation of radiation doses to the patients and medical personnel.

2012-12-01

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

Human rotavirus (RV) infection is a leading cause of dehydrating diarrhea in infants and young children worldwide. Since therapeutic approaches to RV gastroenteritis are limited to alleviation of dehydration with oral rehydration solutions, more direct approaches to palliate symptoms of RV gastroenteritis are required. Treatments with probiotics have been increasingly recognized as alternative safe and low cost treatments for moderate infectious diarrhea. In this study, Bifidobacterium bifidum G9-1 (BBG9-1), which has been used as an intestinal drug for several decades, was shown to have a remarkable protective effect against RV gastroenteritis in a suckling mice model. As well as prophylactic oral administration of BBG9-1 from 2 days before RV infection, therapeutic oral administration of BBG9-1 from 1 day after RV infection significantly alleviated RV-induced diarrhea. Therapeutic administration of BBG9-1 reduced various types of damage in the small intestine, such as epithelial vacuolization and villous shortening, and significantly diminished the infectious RV titer in mixtures of cecal contents and feces. It was also shown that therapeutic administration of BBG9-1 significantly increased the number of acidic mucin-positive goblet cells and the gene expression of mucosal protective factors including MUC2, MUC3, MUC4, TGFβ1 and TFF3 in the small intestine. This led to alleviation of low gut permeability shown as decreased gene expression levels of occludin, claudin-1 and villin-1 after RV infection. Furthermore, in the small intestine, therapeutic administration of BBG9-1 significantly palliated the decreased gene expression of SGLT-1, which plays an important role in water absorption. In the large intestine, administered BBG9-1 was shown to replicate to assimilate undigested nutrients, resulting in normalization of the abnormally high osmotic pressure. These results suggested that water malabsorption caused by RV infection was alleviated in mice administered

Recommended for decades, the therapeutic value of adrenaline (epinephrine) in the resuscitation of patients with out-of-hospital cardiac arrest (OHCA) is controversial. To investigate the possible time-dependent outcomes associated with adrenaline administration by Emergency Medical Services personnel (EMS). A retrospective analysis of prospectively collected data from a near statewide cardiac resuscitation database between 1 January 2005 and 30 November 2013. Multivariable logistic regression was used to analyze the effect of the time interval between EMS dispatch and the initial dose of adrenaline on survival. The primary endpoints were survival to hospital discharge and favourable neurologic outcome. Data from 3469 patients with witnessed OHCA were analyzed. Their mean age was 66.3 years and 69% were male. An initially shockable rhythm was present in 41.8% of patients. Based on a multivariable logistic regression model with initial adrenaline administration time interval (AATI) from EMS dispatch as the covariate, survival was greatest when adrenaline was administered very early but decreased rapidly with increasing (AATI); odds ratio 0.94 (95% Confidence Interval (CI) 0.92-0.97). The AATI had no significant effect on good neurological outcome (OR=0.96, 95% CI=0.90-1.02). In patients with OHCA, survival to hospital discharge was greater in those treated early with adrenaline by EMS especially in the subset of patients with a shockable rhythm. However survival rapidly decreased with increasing adrenaline administration time intervals (AATI). Copyright © 2015 The Authors. Published by Elsevier Ireland Ltd.. All rights reserved.

Intranasal administration of a therapeutic HIV vaccine (Vacc-4x induces dose-dependent systemic and mucosal immune responses in a randomized controlled trial.

Directory of Open Access Journals (Sweden)

Kristin Brekke

Full Text Available Vacc-4x, a Gag p24-based therapeutic HIV vaccine, has been shown to reduce viral load set-points after intradermal administration. In this randomized controlled pilot study we investigate intranasal administration of Vacc-4x with Endocine as adjuvant.Safety and immunogenicity were tested in patients on effective ART. They were randomized to low, medium or high dose Vacc-4x or adjuvant alone, administered four times at weekly intervals with no booster. Vacc-4x-specific T cell responses were measured in vitro by proliferation and in vivo by a single DTH skin test at the end of study. Nasal and rectal mucosal secretions were analyzed for Vacc-4x-specific antibodies by ELISA. Immune regulation induced by Vacc-4x was assessed by functional blockade of the regulatory cytokines IL-10 and TGF-β.Vacc-4x proliferative T cell responses increased only among the vaccinated (p ≤ 0.031. The low dose group showed the greatest increase in Vacc-4x CD8+T cell responses (p = 0.037 and developed larger DTH (p = 0.005 than the adjuvant group. Rectal (distal Vacc-4x IgA and IgG antibodies also increased (p = 0.043 in this group. In contrast, the high dose generated higher nasal (local Vacc-4x IgA (p = 0.028 and serum IgG (p = 0.030 antibodies than the adjuvant. Irrespective of dose, increased Vacc-4x CD4+T cell responses were associated with low proliferation (r = -0.82, p < 0.001 and high regulation (r = 0.61, p = 0.010 at baseline.Intranasal administration of Vacc-4x with Endocine was safe and induced dose-dependent vaccine-specific T cell responses and both mucosal and systemic humoral responses. The clinical significance of dose, immune regulation and mucosal immunity warrants further investigation.ClinicalTrials.gov NCT01473810.

Philanthropic dilemmas and the nurse administrator role.

Science.gov (United States)

Klein, Tracy

2014-01-01

Nurse administrators are in a position to encounter ethical dilemmas when evaluating philanthropic proposals. Nurses may have little formal training in ethics, or they may be most experienced with ethical frameworks that apply primarily to clinical patient encounters. Gifts of goods, services, education, or other benefits to nurses may create ethical dilemmas. Philanthropic ethics and potential dilemmas are discussed in nonnursing professions such as medicine and nonprofit administration but rarely explored in the nursing administration context. Nurse administrators in a position to evaluate generous offers of philanthropy should identify key components to fully assess the ethics of their receipt. A survey of several resources is done to provide nurse administrators with the foundation to develop policies related to philanthropy if they are absent, preferably in advance of the offer. Recommendations for assessment and evaluation of philanthropic proposals are provided to aid nurse administrators in their synthesis and application of ethical principles from multiple sources.

The route of administration (oral vs intravenous) does not influence dose or outcome in Graves' disease and unifocal autonomy

2005-01-01

In a prospective randomised study, we investigated the influence of the route of administration of radioiodide on dosimetry and therapy outcome. Fifty-four patients suffering from Graves' disease (GD) and 60 patients with unifocal autonomy (UA) participated in the study and were randomly treated with either orally or intravenously administered radioiodide. Pretherapeutic dosimetry was based on single uptake measurements with a calibrated uptake probe system. The radioiodine kinetics during hospitalisation was assessed by daily bedside uptake measurements. Therapeutic dose was determined by half-life and thyroid uptake at the time of discharge using the same uptake probe as for the radioiodine test. No improvement in accuracy of dosimetry was achieved when radioiodide was administered intravenously. Mean therapeutic doses were identical following intravenous or oral administration. Variation in the achieved dose was slightly higher in the patients receiving oral administration, this being attributable to larger deviations in discrete activities of the capsules administered as compared with the values determined by dosimetry. No differences according to treatment modality were found with regard to therapeutic outcome. Eighty-seven patients attended 6-month follow-up after therapy. In the UA group, successful treatment, defined as a normal or elevated TSH level, was observed in 94% of patients after oral administration and in 80% after intravenous administration; corresponding figures in the GD group were 68% and 65%. The causes of individual differences between targeted and therapeutically achieved doses remain undetermined. Variations in the bioavailability of radioiodide or other parameters affecting thyroid status may be involved, and further investigations are needed to clarify this. (orig.)

Aims The aims of the study were to compare [14C]-paracetamol ([14C]-PARA) paediatric pharmacokinetics (PK) after administration mixed in a therapeutic dose or an isolated microdose and to develop further and validate accelerator mass spectrometry (AMS) bioanalysis in the 0–2 year old age group. Methods [14C]-PARA concentrations in 10–15 µl plasma samples were measured after enteral or i.v. administration of a single [14C]-PARA microdose or mixed in with therapeutic dose in infants receiving PARA as part of their therapeutic regimen. Results Thirty-four infants were included in the PARA PK analysis for this study: oral microdose (n = 4), i.v. microdose (n = 6), oral therapeutic (n = 6) and i.v. therapeutic (n = 18). The respective mean clearance (CL) values (SDs in parentheses) for these dosed groups were 1.46 (1.00) l h–1, 1.76 (1.07) l h–1, 2.93 (2.08) l h–1 and 2.72 (3.10) l h–1, t1/2 values 2.65 h, 2.55 h, 8.36 h and 7.16 h and dose normalized AUC(0-t) (mg l–1 h) values were 0.90 (0.43), 0.84 (0.57), 0.7 (0.79) and 0.54 (0.26). Conclusions All necessary ethical, scientific, clinical and regulatory procedures were put in place to conduct PK studies using enteral and systemic microdosing in two European centres. The pharmacokinetics of a therapeutic dose (mg kg–1) and a microdose (ng kg–1) in babies between 35 to 127 weeks post-menstrual age. [14C]-PARA pharmacokinetic parameters were within a two-fold range after a therapeutic dose or a microdose. Exploratory studies using doses significantly less than therapeutic doses may offer ethical and safety advantages with increased bionalytical sensitivity in selected exploratory paediatric pharmacokinetic studies.

The aims of the study were to compare [(14)C]-paracetamol ([(14)C]-PARA) paediatric pharmacokinetics (PK) after administration mixed in a therapeutic dose or an isolated microdose and to develop further and validate accelerator mass spectrometry (AMS) bioanalysis in the 0-2 year old age group. [(14)C]-PARA concentrations in 10-15 µl plasma samples were measured after enteral or i.v. administration of a single [(14)C]-PARA microdose or mixed in with therapeutic dose in infants receiving PARA as part of their therapeutic regimen. Thirty-four infants were included in the PARA PK analysis for this study: oral microdose (n = 4), i.v. microdose (n = 6), oral therapeutic (n = 6) and i.v. therapeutic (n = 18). The respective mean clearance (CL) values (SDs in parentheses) for these dosed groups were 1.46 (1.00) l h(-1), 1.76 (1.07) l h(-1), 2.93 (2.08) l h(-1) and 2.72 (3.10) l h(-1), t(1/2) values 2.65 h, 2.55 h, 8.36 h and 7.16 h and dose normalized AUC(0-t) (mg l(-1) h) values were 0.90 (0.43), 0.84 (0.57), 0.7 (0.79) and 0.54 (0.26). All necessary ethical, scientific, clinical and regulatory procedures were put in place to conduct PK studies using enteral and systemic microdosing in two European centres. The pharmacokinetics of a therapeutic dose (mg kg(-1)) and a microdose (ng kg(-1)) in babies between 35 to 127 weeks post-menstrual age. [(14)C]-PARA pharmacokinetic parameters were within a two-fold range after a therapeutic dose or a microdose. Exploratory studies using doses significantly less than therapeutic doses may offer ethical and safety advantages with increased bionalytical sensitivity in selected exploratory paediatric pharmacokinetic studies. © 2015 The British Pharmacological Society.

Full Text Available Nanogels are drug delivery systems that can bypass the blood-brain barrier and deliver drugs to the desired site when administered intranasally. They have been used as a drug delivery platform for the management of brain diseases such as Alzheimer disease, migraine, schizophrenia and depression. nanogels have also been developed as vaccine carriers for the protection of bacterial infections such as influenza, meningitis, pneumonia and as veterinary vaccine carriers for the protection of animals from encephalomyelitis and mouth to foot disease. It has been developed as vaccine carriers for the prevention of lifestyle disease such as obesity. Intranasal administration of therapeutics using nanogels for the management of brain diseases revealed that the drug transportation was via the olfactory nerve pathway resulting in rapid drug delivery to the brain with excellent neuroprotective effect. The application of nanogels as vaccine carriers also induced significant responses associated with protective immunity against selected bacterial and viral infections. This review provides a detailed information on the enhanced therapeutic effects, mechanisms and biological efficacy of nanogels for intranasal administration.

Full Text Available The most disadvantadged neighborhoods in Europe have received funds from State Administration to eradicate social exclusion and overcome processes of urban ghettoization. These processes are being implemented in several social areas such as housing, employment, and education. Actions, defined as "good practices", are usually valued by the quantity and type and not by the quality and final outcomes they achieve. For example, when they improve the living conditions of the populations in these areas. The INCLUD-ED project shows positive results by replacing these "good practices" by "successful actions". They are grounded on scientific evidence in order to respond to the aims set by the neighbours of these disadvantaged neighborhoods.

Full Text Available Therapeutic protein drugs are an important class of medicines serving patients most in need of novel therapies. Recently approved recombinant protein therapeutics have been developed to treat a wide variety of clinical indications, including cancers, autoimmunity/inflammation, exposure to infectious agents, and genetic disorders. The latest advances in protein-engineering technologies have allowed drug developers and manufacturers to fine-tune and exploit desirable functional characteristics of proteins of interest while maintaining (and in some cases enhancing product safety or efficacy or both. In this review, we highlight the emerging trends and approaches in protein drug development by using examples of therapeutic proteins approved by the U.S. Food and Drug Administration over the previous five years (2011–2016, namely January 1, 2011, through August 31, 2016.

Current United States Food and Drug Administration (FDA)-approved lithium salts are plagued with a narrow therapeutic window. Recent attempts to find alternative drugs have identified new chemical entities, but lithium's polypharmacological mechanisms for treating neuropsychiatric disorders are highly debated and are not yet matched. Thus, re-engineering current lithium solid forms in order to optimize performance represents a low cost and low risk approach to the desired therapeutic outcome. In this contribution, we employed a crystal engineering strategy to synthesize the first ionic cocrystals (ICCs) of lithium salts with organic anions. We are unaware of any previous studies that have assessed the biological efficacy of any ICCs, and encouragingly we found that the new speciation did not negatively affect established bioactivities of lithium. We also observed that lithium ICCs exhibit modulated pharmacokinetics compared to lithium carbonate. Indeed, the studies detailed herein represent an important advancement in a crystal engineering approach to a new generation of lithium therapeutics.

The role of oxidative stress in Huntington's disease: are antioxidants good therapeutic candidates?

Science.gov (United States)

Gil-Mohapel, Joana; Brocardo, Patricia S; Christie, Brian R

2014-04-01

Huntington's disease (HD) is the most common polyglutamine neurodegenerative disorder in humans, and is caused by a mutation of an unstable expansion of CAG repeats within the coding region of the HD gene, which expresses the protein huntingtin. Although abnormal protein is ubiquitously expressed throughout the organism, cell degeneration occurs mainly in the brain, and there, predominantly in the striatum and cortex. The mechanisms that account for this selective neuronal death are multifaceted in nature and several lines of evidence suggest that mitochondrial dysfunction, overproduction of reactive oxygen species (ROS) and oxidative stress (an imbalance between pro-oxidant and antioxidant systems resulting in oxidative damage to proteins, lipids and DNA) might play important roles. Over time, this can result in the death of the affected neuronal populations. In this review article we present an overview of the preclinical and clinical studies that have indicated a link between oxidative stress, neurodegeneration, and cell death in HD. We also discuss how changes in ROS production affect neuronal survival, highlighting the evidence for the use of antioxidants including essential fatty acids, coenzyme Q10, and creatine, as potential therapeutic strategies for the treatment of this devastating neurodegenerative disorder.

Financialization may affect the therapeutic relationship in psychotherapy

Marcin Jacek Jabłoński

2015-04-01

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

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

Introduction: Therapeutic application of intravenous administered (IV) human bone marrow-derived mesenchymal stem cells (ahMSCs) appears to have as main drawback the massive retention of cells in the lung parenchyma, questioning the suitability of this via of administration. Intraarticular administration (IAR) could be considered as an alternative route for therapy in degenerative and traumatic joint lesions. Our work is outlined as a comparative study of biodistribution of 99m Tc-ahMSCs after IV and IAR administration, via scintigraphic study in an animal model. Methods: Isolated primary culture of adult human mesenchymal stem cells was labeled with 99m Tc-HMPAO for scintigraphic study of in vivo distribution after intravenous and intra-articular (knee) administration in rabbits. Results: IV administration of radiolabeled ahMSCs showed the bulk of radioactivity in the lung parenchyma while IAR images showed activity mainly in the injected cavity and complete absence of uptake in pulmonary bed. Conclusions: Our study shows that IAR administration overcomes the limitations of IV injection, in particular, those related to cells destruction in the lung parenchyma. After IAR administration, cells remain within the joint cavity, as expected given its size and adhesion properties. Advances in knowledge: Intra-articular administration of adult human mesenchymal stem cells could be a suitable route for therapeutic effect in joint lesions. Implications for patient care: Local administration of adult human mesenchymal stem cells could improve their therapeutic effects, minimizing side effects in patients.

Bone fracture healing is processed through multiple biological stages including the transition from cartilaginous callus to bony callus formation. Because of its specific, temporal and indispensable functions demonstrated by mouse genetic studies, Hedgehog (Hh) signaling is one of the most potent signaling pathways involved in these processes, but the effect of Hh-signaling activation by small compounds on the repair process had not yet been addressed. Here we examined therapeutic effects of local and one shot-administration of the Hh agonist known as smoothened agonist (SAG) on bone fracture healing in a mouse model. A quantitative analysis with three-dimensional micro-computed tomography showed that SAG administration increased the size of both the cartilaginous callus and bony callus at 14 days after the surgery. A histological analysis showed that SAG administration increased the number of cells expressing a proliferation marker and a chondrocyte marker in cartilaginous callus as well as the cells expressing an osteoblast marker in bony callus. These results indicate that the SAG administration resulted in an enhancement of callus formation during bone fracture healing, which is at least in part mediated by an increase in chondrocyte proliferation in cartilaginous callus and the promotion of bone formation in bony callus. Therapeutic strategies with a SAG-mediated protocol may thus be useful for the treatment of bone fractures. - Highlights: • Local administration of a Hh agonist accelerates callus formation. • The Hh agonist administration promotes chondrocyte proliferation in the soft callus. • The Hh agonist administration increases osteoblast formation in the hard callus.

Germinal matrix hemorrhage is a leading cause of mortality and morbidity from prematurity. This brain region is vulnerable to bleeding and re-bleeding within the first 72 hours of preterm life. Cerebroventricular expansion of blood products contributes to the mechanisms of brain injury. Consequences include lifelong hydrocephalus, cerebral palsy, and intellectual disability. Unfortunately little is known about the therapeutic needs of this patient population. This review discusses the mechanisms of germinal matrix hemorrhage, the animal models utilized, and the potential therapeutic targets. Potential therapeutic approaches identified in pre-clinical investigations include corticosteroid therapy, iron chelator administration, and transforming growth factor-β pathway modulation, which all warrant further investigation. Thus, effective preclinical modeling is essential for elucidating and evaluating novel therapeutic approaches, ahead of clinical consideration.

Good agreement between questionnaire and administrative databases for health care use and costs in patients with osteoarthritis

Directory of Open Access Journals (Sweden)

Robertson M Clare

2011-04-01

Full Text Available Abstract Background Estimating costs is essential to the economic analysis of health care programs. Health care costs are often captured from administrative databases or by patient report. Administrative records only provide a partial representation of health care costs and have additional limitations. Patient-completed questionnaires may allow a broader representation of health care costs; however the validity and feasibility of such methods have not been firmly established. This study was conducted to assess the validity and feasibility of using a patient-completed questionnaire to capture health care use and costs for patients with osteoarthritis, and to compare the research costs of the data-capture methods. Methods We designed a patient questionnaire and applied it in a clinical trial. We captured equivalent data from four administrative databases. We evaluated aspects of the questionnaire's validity using sensitivity and specificity, Lin's concordance correlation coefficient (ρc, and Bland-Altman comparisons. Results The questionnaire's response rate was 89%. Acceptable sensitivity and specificity levels were found for all types of health care use. The numbers of visits and the majority of medications reported by patients were in agreement with the database-derived estimates (ρc > 0.40. Total cost estimates from the questionnaire agreed with those from the databases. Patient-reported co-payments agreed with administrative records with respect to GP office transactions, but not pharmaceutical co-payments. Research costs for the questionnaire-based method were less than one-third of the costs for the databases method. Conclusion A patient-completed questionnaire is feasible for capturing health care use and costs for patients with osteoarthritis, and data collected using it mostly agree with administrative databases. Caution should be exercised when applying unit costs and collecting co-payment data.

Therapeutic strategies to improve control of hypertension.

Science.gov (United States)

Armario, Pedro; Waeber, Bernard

2013-03-01

Blood pressure is poorly controlled in most European countries and the control rate is even lower in high-risk patients such as patients with chronic kidney disease, diabetic patients or previous coronary heart disease. Several factors have been associated with poor control, some of which involve the characteristic of the patients themselves, such as socioeconomic factors, or unsuitable life-styles, other factors related to hypertension or to associated comorbidity, but there are also factors directly associated with antihypertensive therapy, mainly involving adherence problems, therapeutic inertia and therapeutic strategies unsuited to difficult-to-control hypertensive patients. It is common knowledge that only 30% of hypertensive patients can be controlled using monotherapy; all the rest require a combination of two or more antihypertensive drugs, and this can be a barrier to good adherence and log-term persistence in patients who also often need to use other drugs, such as antidiabetic agents, statins or antiplatelet agents. The fixed combinations of three antihypertensive agents currently available can facilitate long-term control of these patients in clinical practice. If well tolerated, a long-term therapeutic regimen that includes a diuretic, an ACE inhibitor or an angiotensin receptor blocker, and a calcium channel blocker is the recommended optimal triple therapy.

Oxime HI-6 is an acetylcholinesterase reactivator therapeutically efficient against nerve agents. Because of their physico-chemical properties, oximes are typically applied intramuscularly (i.m.). This route of administration has also some disadvantages, and alternative strategies ought to be examined. We evaluated the pharmacokinetic profiles of two HI-6 salts after their intravenous (i.v.) administration, and compare the results with the known pharmacokinetics after i.m. administration. Pigs were administered with HI-6 salts (i.v), either HI-6 dichloride (10.71 mg/kg) or molar equivalent HI-6 dimethansulphonate (13.59 mg/kg). Doses of the HI-6 salts corresponded with a standard HI-6 dichloride dose in one autoinjector (500 mg) and were recalculated for one kilogram of body weight. The main pharmacokinetic parameters are comparable after i.v. and i.m. HI-6 administration. The compared pharmacokinetic parameters were half-life, terminal rate constant, mean residence time of the molecule in the body, clearance, and the apparent volume in the terminal phase. The bioavailability after i.m. administration was comparable with that of i.v.; these results suggest that the oxime is well released from the muscle depot. Significant differences were found in parameters Cmax and Tmax which are important in cases of emergency when rapidity and bioavailability are paramount for the success of treatment. I.v. administration should solve the problem of rapid clearance. Infusion or bolus administration may be considered as a logical subsequent step in oxime treatment strategy. The main advantage is in maintenance of an effective therapeutic plasma concentration, a more easily achievable effective therapeutic concentration, and fewer local adverse reactions.

Allogenic banking of dental pulp stem cells for innovative therapeutics.

2015-08-26

Medical research in regenerative medicine and cell-based therapy has brought encouraging perspectives for the use of stem cells in clinical trials. Multiple types of stem cells, from progenitors to pluripotent stem cells, have been investigated. Among these, dental pulp stem cells (DPSCs) are mesenchymal multipotent cells coming from the dental pulp, which is the soft tissue within teeth. They represent an interesting adult stem cell source because they are recovered in large amount in dental pulps with non-invasive techniques compared to other adult stem cell sources. DPSCs can be obtained from discarded teeth, especially wisdom teeth extracted for orthodontic reasons. To shift from promising preclinical results to therapeutic applications to human, DPSCs must be prepared in clinical grade lots and transformed into advanced therapy medicinal products (ATMP). As the production of patient-specific stem cells is costly and time-consuming, allogenic biobanking of clinical grade human leukocyte antigen (HLA)-typed DPSC lines provides efficient innovative therapeutic products. DPSC biobanks represent industrial and therapeutic innovations by using discarded biological tissues (dental pulps) as a source of mesenchymal stem cells to produce and store, in good manufacturing practice (GMP) conditions, DPSC therapeutic batches. In this review, we discuss about the challenges to transfer biological samples from a donor to HLA-typed DPSC therapeutic lots, following regulations, GMP guidelines and ethical principles. We also present some clinical applications, for which there is no efficient therapeutics so far, but that DPSCs-based ATMP could potentially treat.

Full Text Available Land is one of the most major capitals in our life. Without it, sustainability of human existence is very impossible. Unfortunately, land problems in Indonesia have unique challenges compared to other countries. Many of kinds of challenges are in the form of the natural disasters. This paper is going to measure how well the principles of good governance has been incorporated in the Yogyakarta Special Region Land administration System generally by studying on the Merapi Disaster Mitigation, particularly in how  land planning for the Merapi Disaster’s victims is performed. The research methodology employs a combined research method, it means that fundamental principles in process and its output of both the doctrinal and non doctrinal approaches is synergized to based on the research’s activity unites. Configuration of  the land administration systems in achieving people prosperity has been affected by evolution of political, cultural, and legal awareness of local communities and central government policy. To conclude, incorporating a disaster response based land policy principles requires an integrated law and policy making system among parties through the implementation of good governance principle in the record of public participation voices and sustainable development interests. Notable reports illustrate that the good land governance incorporation encouraged and inspired land planning system to be more efficient and effective. Particularly in the natural disaster mitigation and reconstruction, incorporating good land governance principles furthermore encourages land policy makers to achieve the responsive land management in line with social demands and sustainable development programs.

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

The findings help describe their responsibilities in the treatment and management of ocular diseases and their use of diagnostic and therapeutic drugs. The study also investigated what, if any, role optometrists play beyond care in the education and research practices of the hospital. A descriptive analysis was conducted through the use of surveys and interviews of department chiefs or medical directors. A survey was sent out to 149 Veterans Affairs (VA) Hospitals, located using the VA facility locator Web site. Data were tabulated, aggregated, and analyzed. A response rate of 81% was achieved (122 surveys returned), 98% of which (120 facilities) provide eye services to their patients in either an outpatient or inpatient capacity. One hundred seventeen (98%) of these had optometrists affiliated with their facility. These optometrists were responsible for providing a range of services, prescribing the use of diagnostic or therapeutic drugs, and participating in educational training of other health personnel. Optometry has developed a strong partnership with the Veterans Health Administration, and act as an integral part of its hospital services. The VA has developed a workforce mix that should serve as a model for managed care organizations.

BRIT is a manufacturer and supplier of therapeutic doses (100 mCi) of the radiopharmaceutical 131 I-mIBG to various nuclear medicine centers in India. The therapeutic formulation is of high radioactive concentration (>10 mCi/ml) and is thus prone to radiolytic damage during transport, storage until administration. Earlier stability studies at this laboratory were done using conventional methods like Thin Layer Chromatography (TLC) which has an inherent limitation in terms of resolution. In view of this, a suitable HPLC method has been developed and the stability of therapeutic 131 I-mIBG was monitored at various conditions

The human rectum represents a body cavity in which drugs can be easily introduced and retained and from which absorption is well possible. There are important therapeutic reasons why it is sometimes preferable to give a drug rectally rather than orally, e.g. in cases of nausea and vomiting. Drawbacks of rectal drug administration include the interruption of absorption by defaecation and lack of patient acceptability. The mechanism of drug absorption from the rectum is probably no different to that in the upper part of the gastrointestinal tract, despite the fact that the physiological circumstances (e.g. pH, fluid content) differ substantially, Absorption from aqueous and alcoholic solutions may occur very rapidly, which has proved to be of considerable therapeutic value in the rapid suppression of acute convulsive attacks by diazepam (e.g. in children), but absorption from suppositories is generally slower and very much dependent on the nature of the suppository base, the use of surfactants or other additives, particle size of the active ingredient, etc. There is some evidence that hepatic first-pass elimination of high clearance drugs is partially avoided after rectal administration, e.g. lignocaine. This can be explained by the rectal venous blood supply: the upper part is connected with the portal system, whereas the lower part is directly connected with the systemic circulation. Plasma concentration data following rectal administration of representatives of several classes of drugs are reviewed: anticonvulsants, non-narcotic analgesics and non-steroidal anti-inflammatory agents, hypnosedatives and anaesthetics, strong analgesics, theophylline and derivatives, corticosteroids, antibacterial agents, thiazinamium, promethazine, hyoscine-N-butyl-bromide, streptokinase, progesterone, ergotamine tartrate and levodopa. Only limited number of cases has it been adequately shown that the rectal route of administration gives plasma concentrations which are comparable to

Rheumatoid factor interference in immunogenicity assays for human monoclonal antibody therapeutics.

Science.gov (United States)

Tatarewicz, Suzanna; Miller, Jill M; Swanson, Steven J; Moxness, Michael S

2010-05-31

Rheumatoid factors (RFs) are endogenous human antibodies that bind to human gamma globulins. RFs demonstrate preferential binding to aggregated gamma globulins and are involved in the clearing mechanism of immune complexes. Immunoassays designed to measure human anti-human antibodies (HAHA) after administration of monoclonal antibody therapeutics are thus vulnerable to interference from RFs. When using a sensitive electrochemiluminescent (ECL) bridging immunoassay, samples from subjects with rheumatoid arthritis demonstrated much higher baseline reactivity than healthy subjects. Interference was found to be dependent on the aggregation state of the therapeutic antibody that had been conjugated with the detection reagent (ruthenium). Size exclusion high performance liquid chromatography (SE-HPLC) demonstrated that of the total integrated peaks, as little as 0.55% high molecular weight aggregates (>600kDa) were sufficient to cause increased reactivity. Stability studies of the ruthenium and biotin conjugated therapeutic antibody indicated that storage time, temperature and buffer formulation were critical in maintaining the integrity of the reagents. Through careful SE-HPLC monitoring we were able to choose appropriate storage and buffer conditions which led to a reduction in the false reactivity rate in therapeutic-naïve serum from a rheumatoid arthritis population.

Vaishya, Ravi; Khurana, Varun; Patel, Sulabh; Mitra, Ashim K

2015-03-01

Proteins are effective biotherapeutics with applications in diverse ailments. Despite being specific and potent, their full clinical potential has not yet been realized. This can be attributed to short half-lives, complex structures, poor in vivo stability, low permeability, frequent parenteral administrations and poor adherence to treatment in chronic diseases. A sustained release system, providing controlled release of proteins, may overcome many of these limitations. This review focuses on recent development in approaches, especially polymer-based formulations, which can provide therapeutic levels of proteins over extended periods. Advances in particulate, gel-based formulations and novel approaches for extended protein delivery are discussed. Emphasis is placed on dosage form, method of preparation, mechanism of release and stability of biotherapeutics. Substantial advancements have been made in the field of extended protein delivery via various polymer-based formulations over last decade despite the unique delivery-related challenges posed by protein biologics. A number of injectable sustained-release formulations have reached market. However, therapeutic application of proteins is still hampered by delivery-related issues. A large number of protein molecules are under clinical trials, and hence, there is an urgent need to develop new methods to deliver these highly potent biologics.

An overview of leech and its therapeutic applications

2015-05-01

Full Text Available Hirudotherapy has a broad spectrum of therapeutic application in the medical field ranging from cardiology, gynaecology, ophthalmology, plastic and reconstructive surgeries. In medieval and early modern medicine, leeches were used to remove blood from patients in an attempt to balance the biological humours. Leeches are widely used to treat venous congestion in microvascular replantation, free and conventional flap surgery and traumatology. Recently, Food and Drug Administration has approved the usage of live leeches as medical device for therapeutic applications. Presently, some of the leech species have declined dramatically in its population due to the over utilization of leech for medicinal purposes and also due to pollution in several parts of the world particularly in European and Asian countries. This review presents an overview of leech including the history, biology, classification, and its application as medical device. Further, it also covers the controversies and misconception related to leech species identification and complications of post hirudotherapy.

TAX ADMINISTRATION: SOME ISSUES AND TRENDS

Full Text Available This paper presents a series of practices of tax administrations in different countries of the world, focusing on their functions, mission and responsibilities. Analyzing the main features of tax administrations across the globe, from emerging to top-level, allows self-assessments of their organizations' strengths and weaknesses to describe the current level and identify the steps needed to move to a new level of maturity but I believe that the applicability of best practice should be made after a rigorous analysis of the expected impact and there must be taken into account the differences in national institutional systems, customs, technological progress and the natural resources. A modern and performing tax administration must pay particular attention to the practice of self-evaluation and voluntary compliance, cost reduction and burden diminuation for taxpayers to provide the goods and services needed to increase the standard of living of citizens and ensure economic prosperity. The tax administration plays an important role in developing and modifying fiscal policies by working with other state institutions to monitor the positive or negative impact of fiscal policy and legislation on tax administration, recommending the necessary changes. Studying the best practices of tax administrations around the world can lead to the achievement and maintenance of a high degree of self-assessment and voluntary compliance of taxpayers' tax obligations - the primary objective of any tax administration.

Gene therapy offers greater opportunities for treating numerous incurable diseases from genetic disorders, infections, and cancer. However, development of appropriate delivery systems could be one of the most important factors to overcome numerous biological barriers for delivery of various therapeutic molecules. A number of nonviral polymer-mediated vectors have been developed for DNA delivery and offer the potential to surmount the associated problems of their viral counterpart. To address the concerns associated with safety issues, a wide range of polymeric vectors are available and have been utilized successfully to deliver their therapeutics in vivo. Today's research is mainly focused on the various natural or synthetic polymer-based delivery carriers that protect the DNA molecule from degradation, which offer specific targeting to the desired cells after systemic administration, have transfection efficiencies equivalent to virus-mediated gene delivery, and have long-term gene expression through sustained-release mechanisms. This review explores an updated overview of different nonviral polymeric delivery system for delivery of DNA-based therapeutics. These polymeric carriers have been evaluated in vitro and in vivo and are being utilized in various stages of clinical evaluation. Continued research and understanding of the principles of polymer-based gene delivery systems will enable us to develop new and efficient delivery systems for the delivery of DNA-based therapeutics to achieve the goal of efficacious and specific gene therapy for a vast array of clinical disorders as the therapeutic solutions of tomorrow.

Enhancing topical analgesic administration: review and prospect for transdermal and transbuccal drug delivery systems.

Science.gov (United States)

Sanz, Roser; Calpena, Ana C; Mallandrich, Mireia; Clares, Beatriz

2015-01-01

Topical administration is an appealing method for drug delivery due to its non-invasiveness, self-controlled application, avoidance of first-pass metabolism in the liver and reduction of systemic side effects compared to other conventional routes such as oral and parenteral. However, topical administration must overcome the permeable barriers that skin and mucosa represent for the drug to achieve its desired therapeutic effect. Penetration of drugs through human skin is mainly impaired by the stratum corneum- the uppermost keratinized skin layer. In contrast, the stratified squamous epithelium (a nonkeratinized tissue) represents the major physical barrier for transbuccal drug administration in humans. Different technologies have been studied to enhance the bioavailability or local effects of drugs administered through skin and buccal mucosa. Those technologies involve the use of physical or chemical enhancers and new dosage forms such as vesicles, cyclodextrins, nanoparticles and other complex systems. Combinations of these technologies may further increase drug delivery in some cases. As analgesia is one of the main therapeutic effects sought through topical administration, this paper focuses on the review of drug delivery systems to improve the topical and transdermal/transbuccal drug delivery of substances with known analgesic action. A discussion of their possibilities and limitations is also included.

Nanoparticle-mediated delivery of pioglitazone enhances therapeutic neovascularization in a murine model of hindlimb ischemia.

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

Therapeutic Fc-fusion proteins and peptides as successful alternatives to antibodies.

Science.gov (United States)

Beck, Alain; Reichert, Janice M

2011-01-01

Therapeutic antibodies have captured substantial attention due to the relatively high rate at which these products reach marketing approval, and the subsequent commercial success they frequently achieve. In the 2000s, a total of 20 antibodies (18 full-length IgG and 2 Fab) were approved by the Food and Drug Administration (FDA) or European Medicines Agency (EMA). In the 2010s to date, an additional 3 antibodies (denosumab, belimumab, ipilimumab) have been approved and one antibody-drug conjugate (brentuximab vedotin) is undergoing regulatory review and may be approved in the US by August 30, 2011. However, a less heralded group of antibody-based therapeutics comprising proteins or peptides fused with an Fc is following the success of classical antibodies.

2017-12-01

Full Text Available Therapeutic communication is a relatively new area of research in Indonesia. It is widely known that the success of therapeutic communication is largely influenced by the medical providers’ communication effectiveness when dealing with their clients. This paper reports on research that aimed to explore the connection between therapeutic communication and satisfaction and dissatisfaction as experienced by families of child cancer patients. It used a quantitative approach with a cross-sectional design. The sample was the families of child cancer patients who were acccompanying the patients during hospital stay treatment at an Indonesian public hospital in Jakarta over the period December of   2014 – March 2015. There were 23 respondents for the research. The statistical test used was chi-square with an 0.05 level of significance. The result indicated that 56.5% of the respondents were satisfied with the therapeutic communication provided by nursing staff and that those who praticed therapeutic communication well, were 22 times more likely to provide a satisfactory level to the families  of   child  cancer  patients  compared  with  those who  did not  apply good therapeutic communication  (the value of p=0.003 and Odds ratio= 22. Thus, the research indicated that the medical providers’ communication effectiveness was associated with the patients’ satisfaction. We suggest that medical providers be given workshops on how to improve their communication skills to make their clients more satisfied with the medical services.

STUDY ON THE INTERRELATION BETWEEN AURICULAR GOOD CONDUCTION POINT STIMULATION AND THE THERAPEUTIC EFFECT

Institute of Scientific and Technical Information of China (English)

胡智慧; 陈巩荪

2001-01-01

Although, the essence of otopoints remains unknown at the moment, many medical workers have termed them temporarily as "auricular specific stimulating points". They give an explanation that when the internal organs or the body trunk is out of order, tender points, changes of the cutaneous electrical resistance, appearance, colour, etc. may occur at some sites of the auri-cle. The medical workers can use these reactions as a reference for making a diagnosis and stimulate these sites to prevent and treat diseases. These reaction points are also the otopoint. Therefore, the otopoint is also called as tenderpoint, or good conduction point, reaction point, stimulating point or treatment point.

Cape Verde: Marketing Good Governance Kap Verde: Die Vermarktung von Good Governance

Directory of Open Access Journals (Sweden)

Bruce Baker

2009-01-01

Full Text Available Faced with a lack of natural resources Cape Verde has made good governance one of its most marketable products. Running parallel to the institutionalisation of democratic politics there has been an overhaul and growing sophistication in public administration, though certain weaknesses persist. This report argues that it is reform and improvement in this area in particular that has enabled this small island state to punch above its weight and achieve remarkable social, economic and political results. But will the successful formula of the past decade prove sufficient for the future? Poverty and unemployment have by no means been conquered. Much of the economic growth has been based in the tourist sector and the government is well aware of the dangers of over-reliance on a single industry. Cape Verde’s midway location between South America and Europe and its increasing international transport connections will continue to offer advantages to drug traffickers. The next few years of the world financial crisis will show whether marketing good governance is enough and whether this is the model for small resource developing states. Der Inselstaat Kap Verde hat seine Anstrengungen zu guter Regierungsführung (Good Governance erfolgreich demonstriert. Parallel zur Institutionalisierung demokratischer Regierungsstrukturen wurde die Verwaltung reformiert und modernisiert, wenn auch immer noch Problembereiche erkennbar sind.

Aber wird dieses Rezept, das im vergangenen Jahrzehnt seine Wirksamkeit beweisen konnte, auch in Zukunft ausreichend sein? Armut und Unterbeschäftigung sind keineswegs besiegt. Ein Großteil des Wirtschaftswachstums basiert auf dem Tourismussektor; die Regierung ist sich der Gefahr wohl bewusst, die in zu großer Abhängigkeit von einem

Prevalence and likelihood ratio of symptoms in patients with good therapeutic response to Lycopodium clavatum. A retrospective study.

Assessment of the likelihood ratio (LR) of symptoms has been proposed as a rational means for detecting indicators to homeopathic medicines. To investigate the prevalence and LR of symptoms commonly attributed to the homeopathic medicine Lycopodium clavatum (Lyc). Secondarily, to answer the question if experienced homeopaths could intuitively infer which the main symptoms of this medicine are. The presence of 35 selected symptoms, prescribed medicines and therapeutic response were assessed retrospectively. The symptoms' prevalence in the Lyc responding population and the LR of the symptoms compared to their prevalence in the remainder of the population were calculated. Two hundred and two Lyc and 550 non Lyc cases (total 752) were included for analysis. Twenty-two symptoms were confirmed as pertaining to Lyc's semiology (prevalence %; LR): contemptuous (3.3; 6.7), urinary stones history (2.7; 5.4), egotism (5.6; 3.6), dictatorial (33.3; 3.4), haughty (8.7; 3.3), sleeps on abdomen (3.3; 3.3), intolerance to clothing in abdomen (12.0; 3.1), reproaches (4.0; 3.0), helplessness (24.0; 2.7), fear of failure (10.7; 2.6), irritability on waking in the morning (16.7; 2.5), constipation alternating with diarrhea (8.7; 2.5), intolerant to contradiction (59.3; 2.3), want of self confidence (30.0; 2.4), abdominal distension after eating (23.3; 2.1); ailments from anticipation (32.0; 1.9), irritability before menses (23.3; 1.8), conscientious (26.0; 1.6), desire of sweets (52.0; 1.6), desire of chocolate (16.7; 1.6), lack of vital heat (41.3; 1.3), and flatterer (1.3; ∞). Surveyed homeopaths' intuitive inferences correlated well with symptoms' prevalence but not with their LR. Lycopodium's main symptoms are well known by homeopaths, but their knowledge correlates well with the symptoms' prevalence and not with their LR. Retrospective assessment of prevalence and LR of symptoms in good responders might be a means for better selection of symptoms for prospective studies

Payers are faced with making coverage and reimbursement decisions based on the best available evidence. Often these decisions apply to patient populations, provider networks, and care settings not typically studied in clinical trials. Treatment effectiveness evidence is increasingly available from electronic health records, registries, and administrative claims. However, little is known about when and what types of real-world evidence (RWE) studies inform pharmacy and therapeutic (P&T) committee decisions. To evaluate evidence sources cited in P&T committee monographs and therapeutic class reviews and assess the design features and quality of cited RWE studies. A convenience sample of representatives from pharmacy benefit management, health system, and health plan organizations provided recent P&T monographs and therapeutic class reviews (or references from such documents). Two investigators examined and grouped references into major categories (published studies, unpublished studies, and other/unknown) and multiple subcategories (e.g., product label, clinical trials, RWE, systematic reviews). Cited comparative RWE was reviewed to assess design features (e.g., population, data source, comparators) and quality using the Good ReseArch for Comparative Effectiveness (GRACE) Checklist. Investigators evaluated 565 references cited in 27 monographs/therapeutic class reviews from 6 managed care organizations. Therapeutic class reviews mostly cited published clinical trials (35.3%, 155/439), while single-product monographs relied most on manufacturer-supplied information (42.1%, 53/126). Published RWE comprised 4.8% (21/439) of therapeutic class review references, and none (0/126) of the monograph references. Of the 21 RWE studies, 12 were comparative and assessed patient care settings and outcomes typically not included in clinical trials (community ambulatory settings [10], long-term safety [8]). RWE studies most frequently were based on registry data (6), conducted in

Therapeutic alliance in schizophrenia: the role of recovery orientation, self-stigma, and insight.

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

Myasthenia gravis: subgroup classification and therapeutic strategies.

Science.gov (United States)

Gilhus, Nils Erik; Verschuuren, Jan J

2015-10-01

Myasthenia gravis is an autoimmune disease that is characterised by muscle weakness and fatigue, is B-cell mediated, and is associated with antibodies directed against the acetylcholine receptor, muscle-specific kinase (MUSK), lipoprotein-related protein 4 (LRP4), or agrin in the postsynaptic membrane at the neuromuscular junction. Patients with myasthenia gravis should be classified into subgroups to help with therapeutic decisions and prognosis. Subgroups based on serum antibodies and clinical features include early-onset, late-onset, thymoma, MUSK, LRP4, antibody-negative, and ocular forms of myasthenia gravis. Agrin-associated myasthenia gravis might emerge as a new entity. The prognosis is good with optimum symptomatic, immunosuppressive, and supportive treatment. Pyridostigmine is the preferred symptomatic treatment, and for patients who do not adequately respond to symptomatic therapy, corticosteroids, azathioprine, and thymectomy are first-line immunosuppressive treatments. Additional immunomodulatory drugs are emerging, but therapeutic decisions are hampered by the scarcity of controlled studies. Long-term drug treatment is essential for most patients and must be tailored to the particular form of myasthenia gravis. Copyright © 2015 Elsevier Ltd. All rights reserved.

This manual establishes guidelines and principles for use in setting up a sound radiation protection program for work with plutonium. The guidance presented is based on the experiences of Energy Research and Development Administration (ERDA) contractors and those portions of private industry concerned with the operation of plutonium facilities, specifically with the fabrication of mixed oxide reactor fuel. The manual is directed primarily to those facilities which have as their sole purpose the handling of large quantities of plutonium for military or industrial uses. It is not intended for use by facilities engaged in reactor or chemical separation operations nor for partial or occasional use by analytical laboratories; while these facilities would find the manual beneficial, it would be incomplete for their needs. The manual addresses good practices that should be observed by management, staff and designers, since the benefits of a good radiation protection program are the result of their joint efforts. Methods for the diagnostic evaluation of internally deposited Pu are included

Production and evaluation of Lutetium-177 maltolate as a possible therapeutic agent

Hakimi, A.; Jalilian, A. R.; Bahrami Samani, A.; Ghannadi Maragheh, M.

2012-01-01

Development of oral therapeutic radiopharmaceuticals is a new concept in radiopharmacy. Due to the interesting therapeutic properties of 177 Lu and oral bioavailability of maltolate (MAL) metal complexes, 177 Lu-maltolate ( 177 Lu-MAL) was developed as a possible therapeutic compound for ultimate oral administration. The specific activity of 2.6-3 GBq/mg was obtained by irradiation of natural Lu 2 O 3 sample with thermal neutron flux of 4x10 13 n.cm -2 .s -1 for Lu-177. The product was converted into chloride form which was further used for labeling maltol (MAL). At optimized conditions a radiochemical purity of about >99% was obtained for 177 Lu-MAL shown by ITLC (specific activity, 970-1000 Mbq/mmole). The stability of the labeled compound as well as the partition coefficient was determined in the final solution up to 24h. Biodistribution studies of Lu-177 chloride and 177 Lu-MAL were carried out in wild-type rats for post-oral distribution phase data. Lu-MAL is a possible therapeutic agent in human malignancies for the bone palliation therapy so the efficacy of the compound should be tested in various animal models.

Challenges in developing e-government for good governance in North Sumatra

Siahaan, AY

2017-01-01

E-government as one form of public administration reform in Indonesia is increasingly related to the pursuance of good governance. This paper examines the relationship between of e-government and good governance by utilizing the case study design on the implementation of e-procurement in North Sumatra. It reveals centrality of local politics and business culture in understanding resistances of both local government officials and local business which creates loopholes’ for the practice of ‘bad governance’ in all phases of e-procurement in North Sumatra province. Data transparency does not equate and guarantee the realization of good governance. Public knowledge and understanding on government decision making processes and accountability (process and policy transparency) are central to achieve good governance through e-procurement. E-procurement system does not automatically change organizational and working culture of the implementers and suppliers. This paper provides insight to the attitude and the perception of private sector engage in e-procurement towards government in implementing e-government. Resistance, digital divide and local politics interrelatedly obstruct the realization of pursuing good governance through e-procurement.

What's New in Treating Inpatients With Personality Disorders?: Dialectical Behavior Therapy and Old-Fashioned, Good Communication.

Psychiatric unit inpatients often have serious mental illnesses with comorbid personality disorders. Mental illnesses usually respond favorably to medication and psychotherapy, but personality disorders do not. Two personality disorders are commonly seen on inpatient units: borderline and antisocial. These personality disorders may destabilize the milieu with disruptive behaviors and present a challenge to nurses. Difficult patient behaviors and therapeutic responses by nurses are examined. Dialectical behavior therapy techniques and good communication skills may be used by nurses to (a) interact therapeutically with patients with personality disorders and (b) protect other patients and the milieu.

Somatic gene therapy has been proposed as a means to achieve systemic delivery of therapeutic proteins. However, there is limited evidence that current methods of gene delivery can practically achieve this goal. In this study, we demonstrate that, following a single intramuscular administration of a recombinant adeno-associated virus (rAAV) vector containing the beta-galactosidase (AAV-lacZ) gene into adult BALB/c mice, protein expression was detected in myofibers for at least 32 weeks. A single intramuscular administration of an AAV vector containing a gene for human erythropoietin (AAV-Epo) into mice resulted in dose-dependent secretion of erythropoietin and corresponding increases in red blood cell production that persisted for up to 40 weeks. Primary human myotubes transduced in vitro with the AAV-Epo vector also showed dose-dependent production of Epo. These results demonstrate that rAAV vectors are able to transduce skeletal muscle and are capable of achieving sustained expression and systemic delivery of a therapeutic protein following a single intramuscular administration. Gene therapy using AAV vectors may provide a practical strategy for the treatment of inherited and acquired protein deficiencies.

Narcolepsy is a neurological disorder that afflicts 1 in 2000 individuals and is characterized by excessive daytime sleepiness and cataplexy-a sudden loss of muscle tone triggered by positive emotions. Features of narcolepsy include dysregulation of arousal state boundaries as well as autonomic and metabolic disturbances. Disruption of neurotransmission through the hypocretin/orexin (Hcrt) system, usually by degeneration of the HCRT-producing neurons in the posterior hypothalamus, results in narcolepsy. The cause of Hcrt neurodegeneration is unknown but thought to be related to autoimmune processes. Current treatments for narcolepsy are symptomatic, including wake-promoting therapeutics that increase presynaptic dopamine release and anticataplectic agents that activate monoaminergic neurotransmission. Sodium oxybate is the only medication approved by the US Food and Drug Administration that alleviates both sleep/wake disturbances and cataplexy. Development of therapeutics for narcolepsy has been challenged by historical misunderstanding of the disease, its many disparate symptoms and, until recently, its unknown etiology. Animal models have been essential to elucidating the neuropathology underlying narcolepsy. These models have also aided understanding the neurobiology of the Hcrt system, mechanisms of cataplexy, and the pharmacology of narcolepsy medications. Transgenic rodent models will be critical in the development of novel therapeutics for the treatment of narcolepsy, particularly efforts directed to overcome challenges in the development of hypocretin replacement therapy.

Objective: To evaluate the effect of intramyocardial administration of basic fibroblast growth factor on angiogenesis of infarcted myocardium in dogs. Methods: Twenty-four mongrel dogs were randomized into control group and therapeutic group. Acute myocardial infarction was made by ligation of the left anterior descending coronary artery distal to its first diagonal branch. As soon as coronary artery was occluded, 50 mg of basic fibroblast growth factor in 15 ml of saline was injected into the infarcted and border zone in therapeutic group, whereas 15 ml saline alone was used in the same way in control dogs. Every 3 dogs in each group was studied on the 1 st day, the 3 rd day, the 10 th day, and the 17 th day, respectively. Electron microscope was used to observe the growth of capillaries. Angiogenesis was evaluated by immunohistochemical studies with VIII factor. With sensitivity encoded technique, cine MR and MR perfusion imaging were performed on each dog within 3 hours after surgery and before euthanasia to evaluate cardiac function and the characteristics of myocardial perfusion. Results: In therapeutic group, LVEF improved markedly since the 10 th day (on the 10 th day: control group 24.09 ± 3.32, therapeutic group 45.71 ± 6.27; on the 17 th day: control group 31.46 ± 4.60, therapeutic group 53.46 ± 5.24). Hypoenhancement on first pass and hyperenhancement on delayed phase appeared in infarcted myocardium. There were significant differences for the time of upslope, peak time of signal intensity, upslope curves ratio, and contrast enhancement ratio between infarcted and normal myocardium. The size of infarcted myocardium was markedly decreased on the 17 th day [control group (9.04 ± 1.59)%, therapeutic group (4.07 ± 1.20)%]. The capillaries grew actively in therapeutic group and microvessel density was higher in therapeutic group than in control group except the first day (control group and therapeutic group respectively on the 3 rd day: 92.3 ± 11

Diabetes mellitus is a metabolic disorder characterized by hyperglycaemia. Several natural products have been isolated and identified to restore the complications of diabetes. Spirulina maxima is naturally occurring fresh water cyanobacterium, enriched with proteins and essential nutrients. The aim of the study was to determine whether S. maxima could serve as a therapeutic agent to correct metabolic abnormalities induced by excessive fructose administration in Wistar rats. Oral administration of 10 per cent fructose solution to Wistar rats (n = 5 in each group) for 30 days resulted in hyperglycaemia and hyperlipidaemia. Aqueous suspension of S. maxima (5 or 10%) was also administered orally once daily for 30 days. The therapeutic potential of the preparation with reference to metformin (500 mg/kg) was assessed by monitoring various biochemical parameters at 10 day intervals during the course of therapy and at the end of 30 days S. maxima administration. Significant (Pmaxima aquous extract. Co-administration of S. maxima extract (5 or 10% aqueous) with 10 per cent fructose solution offered a significant protection against fructose induced metabolic abnormalities in Wistar rats. The present findings showed that S. maxima exhibited anti-hyperglycaemic, anti-hyperlipidaemic and hepatoprotective activity in rats fed with fructose. Further studies are needed to understand the mechanisms.

Full Text Available Hop (Humulus lupulus L., as a key ingredient for beer brewing, is also a source of many biologically active molecules. A notable compound, 8-prenylnaringenin (8-PN, structurally belonging to the group of prenylated flavonoids, was shown to be a potent phytoestrogen, and thus, became the topic of active research. Here, we overview the pharmacological properties of 8-PN and its therapeutic opportunities. Due to its estrogenic effects, administration of 8-PN represents a novel therapeutic approach to the treatment of menopausal and post-menopausal symptoms that occur as a consequence of a progressive decline in hormone levels in women. Application of 8-PN in the treatment of menopause has been clinically examined with promising results. Other activities that have already been assessed include the potential to prevent bone-resorption or inhibition of tumor growth. On the other hand, the use of phytoestrogens is frequently questioned regarding possible adverse effects associated with long-term consumption. In conclusion, we emphasize the implications of using 8-PN in future treatments of menopausal and post-menopausal symptoms, including the need for precise evidence and further investigations to define the safety risks related to its therapeutic use.

Gremeaux, V; Coudeyre, E

2010-12-01

To evaluate from a review of the literature the interest of using the Internet as a tool for the therapeutic education of patients. A systematic review of Pubmed was carried out using the key words: the Internet, or World Wide Web and patient education, or patient preference, or self-care. The search was restricted to articles in English published between 1990 and 2009. References to the selected articles were also analyzed. Only randomized controlled studies were retained. Thirty-nine articles concerning 20 different diseases met the inclusion criteria and were analyzed. Different types of programs were proposed: informative, interactive, cognitive-behavioral and programs concerning self-management of the disease and the treatment. These different approaches were sometimes compared. The use of quality Internet sites made it possible to induce beneficial changes in lifestyle habits, and to diminish subjective and/or objective symptom severity in chronic invalidating diseases when used as a complement to traditional management. By using the Internet, patients were also able to improve decision-making skills to a degree that was at least as good as that obtained using traditional paper documents. The Internet is an effective complementary tool that can contribute to improving therapeutic education. Nonetheless, healthcare professionals should work with patients to create quality sites that correspond more closely to their expectations. It is also essential for learned societies such as the SOFMER to invest in therapeutic education on the Internet to make quality therapeutic education modules based on factual medical data and complying with good practices available on line.

Science.gov (United States)

Scheen, A J; Paquot, N

2011-04-01

Beyond lifestyle changes, the management of type 2 diabetes comprises the administration of oral glucose-lowering agents, especially the classical metformin-sulfonylurea combination. If such a dual oral therapy could not (any more) obtain an adequate glucose control, intensified management becomes mandatory. Several therapeutic approaches may be proposed at this stage, with some advantages and disadvantages of each of them. The present clinical case aims at illustrating such difficult therapeutic choice. We will provide the pro-contra arguments concerning each therapeutic alternative and describe the practical modalities of an appropriate management according to the patient's characteristics.

Maternally Sequestered Therapeutic Polypeptides – A New Approach for the Management of Preeclampsia

Directory of Open Access Journals (Sweden)

Eric eGeorge

2014-09-01

Full Text Available The last several decades have seen intensive research into the molecular mechanisms underlying the symptoms of preeclampsia. While the underlying cause of preeclampsia is believed to be defective placental development and resulting placental ischemia, it is only recently that the links between the ischemic placenta and maternal symptomatic manifestation have been elucidated. Several different pathways have been implicated in the development of the disorder; most notably production of the anti-angiogenic protein sFlt-1, induction of auto-immunity and inflammation, and production of reactive oxygen species. While the molecular mechanisms are becoming clearer, translating that knowledge into effective therapeutics has proven elusive. Here we describe a number of peptide based therapies we have developed to target theses pathways, and which are currently being tested in preclinical models. These therapeutics are based on a synthetic polymeric carrier elastin-like polypeptide (ELP, which can be synthesized in various sequences and sizes to stabilize the therapeutic peptide and avoid crossing the placental interface. This prevents fetal exposure and potential developmental effects. The therapeutics designed will target known pathogenic pathways, and the ELP carrier could prove to be a versatile delivery system for administration of a variety of therapeutics during pregnancy.

Roman Yuryevich Skokov

2015-12-01

Full Text Available The article presents alternative scenarios of the state regulation of the markets for addictive goods and services which include alcohol and alcohol-containing products, tobacco products, energy drinks, drugs, gambling games. The author reveals the content of inertial, modernizational, monopolistic and prohibitionist scenarios, and systematizes the effective measures which are used in the international practice of state regulation for reducing the number of challenges connected with the consumption of addictive goods and for adequate use of industrial capacities. The analysis conducted in the article touched upon the traditional practical measures on reducing shadow economic activity, realizing home-made products and substitutes, regulating the economic and physical availability, restricting advertising, sponsorship and sales promotion, as well as the measures aimed at the change of consumer behavior in the conditions associated with increased risk, prevention, diagnosis, treatment and rehabilitation. It is determined that none of these measures is not implemented to the full extent in Russia because they are used under the conditions of informal and shadow offers, corruption in government bodies, lobbying, administrative barriers and low-level administrative and business ethics. The author composed a rating of measures effectiveness under alternative scenarios. On the basis of this analysis and the assessment of the development and status of modern society, the theory and practice of regulating addictive goods markets, the conclusion was made about the socio-economic advantages of the state monopoly which allows to minimize the private interest in increasing sales and gaining over-profits, adequately reflects the public interest, standardizes and unifies physical and economic accessibility of these goods and services, proves its efficiency in domestic practice and the experience of Scandinavian countries.

Burn injuries are a leading cause of morbidity including prolonged hospitalization, disfigurement, and disability. Currently there is no Food and Drug Administration-approved burn therapeutics. A clinical distinction of burn injuries from other acute wounds is the event of the so-called secondary burn wound progression within the first week of the injury, in which a burn expands horizontally and vertically from its initial boundary to a larger area. Therefore, an effective therapeutics for bu...

2015-11-01

Use of injectable drugs in newborns represents more than 90% of prescriptions and requires special precautions in order to ensure more safety and efficiency. The aim of this study is to gather errors relating to the administration of injectable drugs and to suggest corrective actions. This descriptive and transversal study has evaluated 300 injectable drug administrations in a neonatology unit. Two hundred and sixty-one administrations have contained an error. Data are collected by direct observations of administrative act. Errors observed are: an inappropriate mixture (2.6% of cases); an incorrect delivery rate (33.7% of cases); incorrect dilutions (26.7% of cases); error in calculation of the dose to be injected (16.7% of cases); error while sampling small volumes (6.3% of cases); error or omission of administration schedule (1% of cases). These data have enabled us to evaluate administration of injectable drugs in neonatology. Different types of errors observed could be a source of therapeutic inefficiency, extended lengths of stay or iatrogenic drug. Following these observations, corrective actions have been undertaken by pharmacists and consist of: organizing training sessions for nursing; developing an explanatory guide for dilution and administration of injectable medicines, which was made available to the clinical service. Collaborative strategies doctor-nurse-pharmacist can help to reduce errors in the medication process especially during his administration. It permits improvement of injectable drugs use, offering more security and better efficiency and contribute to guarantee ideal therapy for patients. Copyright © 2015.

Post-traumatic stress disorder (PTSD) is a disabling psychiatric disorder. As a substantial part of PTSD patients responds poorly to currently available psychotherapies, pharmacological interventions boosting treatment response are needed. Because of its anxiolytic and pro-social properties, the neuropeptide oxytocin (OT) has been proposed as promising strategy for treatment augmentation in PTSD. As a first step to investigate the therapeutic potential of OT in PTSD, we conducted a double-blind, placebo-controlled, cross-over functional MRI study examining OT administration effects (40 IU) on amygdala reactivity toward emotional faces in unmedicated male and female police officers with (n=37, 21 males) and without (n=40, 20 males) PTSD. Trauma-exposed controls were matched to PTSD patients based on age, sex, years of service and educational level. Under placebo, the expected valence-dependent amygdala reactivity (ie, greater activity toward fearful-angry faces compared with happy-neutral faces) was absent in PTSD patients. OT administration dampened amygdala reactivity toward all emotional faces in male and female PTSD patients, but enhanced amygdala reactivity in healthy male and female trauma-exposed controls, independent of sex and stimulus valence. In PTSD patients, greater anxiety prior to scanning and amygdala reactivity during the placebo session were associated with greater reduction of amygdala reactivity after OT administration. Taken together, our results indicate presumably beneficial neurobiological effects of OT administration in male and female PTSD patients. Future studies should investigate OT administration in clinical settings to fully appreciate its therapeutic potential.

To observe the therapeutic effect of total glucosides of paeony (TGP) on lupus nephritis (LN) in MRL/lpr mice. MRL/lpr mice with lupus nephritis were randomized into model group and TGP group. The urinary protein content was detected using Coomassie brilliant blue, and the serum levels of IgG anti-double-stranded DNA (dsDNA) antibodies and antinuclear antibodies (ANA) were measured by enzyme-linked immunosorbent assay (ELISA). The changes in the renal pathology were examined microscopically, and the spleen and thymus were weighed to calculate the spleen and thymus indexes. At 15 and 30 days after TGP administration, the urinary protein content in the TGP group was significantly lower than that in the model group (PTGP treatment significantly lowered the serum levels of anti-dsDNA antibodies and ANA and the weight and index of spleen (PTGP treatment, the urinary protein content and the levels of anti-dsDNA antibodies and ANA decreased significantly at 15 and 30 days after TGP administration (PTGP administration, the urinary protein content was significantly lowered in the TGP group as compared to that at 15 days (PTGP can reduce urinary protein content and serum levels of anti-dsDNA antibodies and ANA, and lessen renal pathology in MRL/lpr mice with lupus nephritis, suggesting its therapeutic effect on lupus nephritis.

Immunogenicity of therapeutic proteins. Part 2: impact of container closures.

Science.gov (United States)

Sharma, Basant

2007-01-01

Immunogenicity as a potential consequence of therapeutic protein administration is increasingly being scrutinized in the biopharmaceuticals industry, particularly with the imminent introduction of biosimilar products. Immunogenicity is an important safety aspect requiring rigorous investigation to fully appreciate its impact. Factors involved in product handling, such as storage temperature, light exposure, and shaking, have been implicated in immunogenicity, while container closure systems are no less important. Intended to provide a stable environment for the dosage form, container closures may also interact with a product, affecting performance and potentially enhancing immunogenicity. Glass surfaces, air-liquid interfaces, and lubricants can mediate protein denaturation, while phthalates in plastics and latex rubber are sources of extractables and leachates that may contaminate a product, causing allergic reactions and increasing immunogenicity. The manufacture of therapeutic proteins therefore requires rigorous safety evaluations not just in the context of the product, but also product containment.

Electroencephalographic neurofeedback: Level of evidence in mental and brain disorders and suggestions for good clinical practice.

The technique of electroencephalographic neurofeedback (EEG NF) emerged in the 1970s and is a technique that measures a subject's EEG signal, processes it in real time, extracts a parameter of interest and presents this information in visual or auditory form. The goal is to effectuate a behavioural modification by modulating brain activity. The EEG NF opens new therapeutic possibilities in the fields of psychiatry and neurology. However, the development of EEG NF in clinical practice requires (i) a good level of evidence of therapeutic efficacy of this technique, (ii) a good practice guide for this technique. Firstly, this article investigates selected trials with the following criteria: study design with controlled, randomized, and open or blind protocol, primary endpoint related to the mental and brain disorders treated and assessed with standardized measurement tools, identifiable EEG neurophysiological targets, underpinned by pathophysiological relevance. Trials were found for: epilepsies, migraine, stroke, chronic insomnia, attentional-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, major depressive disorder, anxiety disorders, addictive disorders, psychotic disorders. Secondly, this article investigates the principles of neurofeedback therapy in line with learning theory. Different underlying therapeutic models are presented didactically between two continua: a continuum between implicit and explicit learning and a continuum between the biomedical model (centred on "the disease") and integrative biopsychosocial model of health (centred on "the illness"). The main relevant learning model is to link neurofeedback therapy with the field of cognitive remediation techniques. The methodological specificity of neurofeedback is to be guided by biologically relevant neurophysiological parameters. Guidelines for good clinical practice of EEG NF concerning technical issues of electrophysiology and of learning are suggested. These require validation by

Background Researchers have the potential to utilize genetic modification (GM) technologies to create a hybrid of “food” and “medicine” that may challenge traditional understandings of what is “natural”. Moral and ethical concerns are likely to arise in any discussion of these therapeutic foods and will affect the integration of products into clinical care and daily life. This study examined how patients with chronic gastrointestinal (GI) diseases view probiotics as future bioengineered therapeutic foods. Methods A multi-site qualitative study consisting of focus groups with chronic GI diseases was conducted at Cleveland Clinic, Mayo Clinic, and Johns Hopkins University Results We conducted twenty-two focus groups with 136 patients with major GI diseases between March and August 2009. GI patients associated the term “natural” with concepts of diminished risk and morally “good”; conversely, patients associated the term “unnatural” with things that are “risky,” “foreign”, and morally “bad”. Readily available unmodified probiotics were more commonly described as “natural” while genetically modified probiotics were more commonly labeled as “unnatural” and “risky”. However, patients acknowledged that not all natural products are safe, nor are unnatural products always harmful. Conclusions If GI patient perspectives are indicative of public perceptions of therapeutic foods, our findings suggest that the potential benefits and risks of clinical and public health initiatives employing therapeutic foods will be understood in moralistic terms. Bioethicists and others should be sensitive to the implicit normative appeals that are often embedded in the language of what is “natural” and “unnatural”. PMID:22773953

Curcumin Nanomedicine: A Road to Cancer Therapeutics

Yallapu, Murali M.; Jaggi, Meena; Chauhan, Subhash C.

2013-01-01

Cancer is the second leading cause of death in the United States. Conventional therapies cause widespread systemic toxicity and lead to serious side effects which prohibit their long term use. Additionally, in many circumstances tumor resistance and recurrence is commonly observed. Therefore, there is an urgent need to identify suitable anticancer therapies that are highly precise with minimal side effects. Curcumin is a natural polyphenol molecule derived from the Curcuma longa plant which exhibits anticancer, chemo-preventive, chemo- and radio-sensitization properties. Curcumin’s widespread availability, safety, low cost and multiple cancer fighting functions justify its development as a drug for cancer treatment. However, various basic and clinical studies elucidate curcumin’s limited efficacy due to its low solubility, high rate of metabolism, poor bioavailability and pharmacokinetics. A growing list of nanomedicine(s) using first line therapeutic drugs have been approved or are under consideration by the Food and Drug Administration (FDA) to improve human health. These nanotechnology strategies may help to overcome challenges and ease the translation of curcumin from bench to clinical application. Prominent research is reviewed which shows that advanced drug delivery of curcumin (curcumin nanoformulations or curcumin nanomedicine) is able to leverage therapeutic benefits by improving bioavailability and pharmacokinetics which in turn improves binding, internalization and targeting of tumor(s). Outcomes using these novel drug delivery systems have been discussed in detail. This review also describes the tumor-specific drug delivery system(s) that can be highly effective in destroying tumors. Such new approaches are expected to lead to clinical trials and to improve cancer therapeutics. PMID:23116309

Precision cut lung slices as test system for candidate therapeutics in organophosphate poisoning.

2017-08-15

Standard therapeutic options in organophosphate (OP) poisoning are limited to the administration of atropine and oximes, a regimen often lacking in efficacy and applicability. Treatment alternatives are needed, preferably covering a broad spectrum of OP intoxications. Although recent research yielded several promising compounds, e.g. bioscavengers, modulators of the muscarinic acetylcholine (ACh) receptor or bispyridinium non-oximes, these substances still need further evaluation, especially regarding effects on the potentially lethal respiratory symptoms of OP poisoning. Aim of this study was the development of an applicable and easy method to test the therapeutic efficiency of such substances. For this purpose, airway responsiveness in viable precision cut lung slices (PCLS) from rats was analysed. We showed that ACh-induced airway contractions were spontaneously reversible in non-poisoned PCLS, whereas in OP poisoned PCLS, contractions were irreversible. This effect could be antagonized by addition of the standard therapeutic atropine, thereby presenting a clear indication for treatment efficiency. Now, candidate therapeutic compounds can be evaluated, based on their ability to counteract the irreversible airway contraction in OP poisoned PCLS. Copyright © 2017 Elsevier B.V.

Skin penetration and tissue permeation after topical administration of diclofenac.

Science.gov (United States)

Hagen, Martina; Baker, Mark

2017-09-01

Topical delivery of drugs is an alternative to oral administration, often with similar efficacy but potentially a more favorable tolerability profile. However, topical formulations need to be able to penetrate the skin and permeate to the target areas in quantities sufficient to exert a therapeutic effect. Many factors can affect this process, including the physicochemical properties of the drug, the formulation used, and the site and mode of application. It is believed that measurement of drug concentrations at the sites of action may be an indicator of their likely efficacy. This review addresses these issues, with reference to topically administered diclofenac in osteoarthritis. Articles relevant to this review were identified after a systematic search of Medline and Embase, using the key words "diclofenac", "topical administration" and "osteoarthritis" in the search strategy. The sparse data available indicate that topical diclofenac can penetrate and permeate to deeper tissues, with a lower plasma to tissue ratio than oral diclofenac. The tissue diclofenac levels after topical delivery are sustained over time (at least several hours). However, there is not enough data to establish how diclofenac levels in the joint compare with IC 50 levels (50% of the maximum inhibition of prostaglandin synthesis) established following oral administration. After topical application, diclofenac can penetrate the skin and permeate to deeper tissues, where it reaches a concentration that appears to be sufficient to exert a therapeutic effect. More robust methods are required for in vivo characterization to better estimate the clinical efficacy of topically applied drugs.

Recombinant IκBα-loaded curcumin nanoparticles for improved cancer therapeutics

2014-01-01

The field of recombinant protein therapeutics has been evolving rapidly, making significant impact on clinical applications for several diseases, including cancer. However, the functional aspects of proteins rely exclusively on their structural integrity, in which nanoparticle mediated delivery offers unique advantages over free proteins. In the present work, a novel strategy has been developed where the nanoparticles (NPs) used for the delivery of the recombinant protein could contribute to enhancing the therapeutic efficacy of the recombinant protein. The transcription factor, NFκB, involved in cell growth and its inhibitor, IκBα, regulates its proliferation. Another similar naturally available molecule, which inhibits the function of NFκB, is curcumin. Hence, we have developed a ‘green synthesis’ method for preparing water-soluble curcumin nanoparticles to stabilize recombinant IκBα protein. The NPs were characterized by UV–vis and fluorescence spectroscopy, transmission electron microscopy (TEM) and dynamic light scattering before administration into human cervical carcinoma (HeLa) and glioblastoma (U87MG) cells. Experimental results demonstrated that this combined module had enhanced therapeutic efficacy, causing apoptotic cell death, which was confirmed by cytotoxicity assay and flowcytometry analyses. The expression of apoptotic genes studied by semi-quantitative reverse transcription PCR delineated the molecular pathways involved in cell death. Thus, our study revealed that the functional delivery of recombinant IκBα-loaded curcumin NPs has promise as a natural-product-based protein therapeutics against cancer cells. (paper)

Oral administration of nano-emulsion curcumin in mice suppresses inflammatory-induced NFκB signaling and macrophage migration.

Directory of Open Access Journals (Sweden)

Nicholas A Young

Full Text Available Despite the widespread use of curcumin for centuries in Eastern medicine as an anti-inflammatory agent, its molecular actions and therapeutic viability have only recently been explored. While curcumin does have potential therapeutic efficacy, both solubility and bioavailability must be improved before it can be more successfully translated to clinical care. We have previously reported a novel formulation of nano-emulsion curcumin (NEC that achieves significantly greater plasma concentrations in mice after oral administration. Here, we confirm the immunosuppressive effects of NEC in vivo and further examine its molecular mechanisms to better understand therapeutic potential. Using transgenic mice harboring an NFκB-luciferase reporter gene, we demonstrate a novel application of this in vivo inflammatory model to test the efficacy of NEC administration by bioluminescent imaging and show that LPS-induced NFκB activity was suppressed with NEC compared to an equivalent amount of curcumin in aqueous suspension. Administration of NEC by oral gavage resulted in a reduction of blood monocytes, decreased levels of both TLR4 and RAGE expression, and inhibited secretion of MCP-1. Mechanistically, curcumin blocked LPS-induced phosphorylation of the p65 subunit of NFκB and IκBα in murine macrophages. In a mouse model of peritonitis, NEC significantly reduced macrophage recruitment, but not T-cell or B-cell levels. In addition, curcumin treatment of monocyte derived cell lines and primary human macrophages in vitro significantly inhibited cell migration. These data demonstrate that curcumin can suppress inflammation by inhibiting macrophage migration via NFκB and MCP-1 inhibition and establish that NEC is an effective therapeutic formulation to increase the bioavailability of curcumin in order to facilitate this response.

Hashan, Hajed; Aljuffali, Ibrahim; Patel, Prisha; Walker, Stuart

This study compares the current regulatory review process and good review practices at the Saudi Food and Drug Authority (SFDA) with those of regulatory agencies in Australia, Canada, and Singapore and identifies opportunities for developing the SFDA as a Regional Centre of Excellence. A questionnaire completed by the SFDA included data regarding the organisation, key milestones, review timelines, and good review practices of the agency. Similar information was obtained within the same timeframe (2014/2015) through the same standard questionnaire regarding the processes and practices for Health Canada, Singapore's Health Sciences Authority, and Australia's Therapeutic Goods Administration. All four regulatory agencies have established target times for scientific assessment and regulatory review, examine dossier sections in parallel, and separate company response time from overall timing. Additionally, all four agencies have instituted good review practices including standard operating procedures, templates, dossier monitoring, and continuous improvement processes, and assign a high priority to transparency in their relationships with the public, healthcare professionals and industry. Of the four agencies, however, only the SFDA requires a Certificate of Pharmaceutical Product (CPP) at the time of the submission and pricing negotiations before final product approval. To assist the SFDA in its efforts to become a Regional Centre of Excellence, it is suggested that the agency explore a risk stratification approach to select dossiers for verification, abridged, or full reviews; use forms of certification other than the CPP; make pricing negotiations independent to the review process; and introduce a feedback process for the quality of the dossier.

Will Synergizing Vaccination with Therapeutics Boost Measles Virus Eradication?

Science.gov (United States)

Plemper, Richard K; Hammond, Anthea L

2014-01-01

Introduction Measles virus is a major human pathogen responsible for approximately 150,000 measles deaths annually. The disease is vaccine preventable and eradication of the virus is considered feasible in principle. However, a herd immunity exceeding 95% is required to prevent sporadic viral outbreaks in a population. Declining disease prevalence combined with public anxieties about vaccination safety has increased vaccine refusal especially in the European region, which has resulted in measles resurgence in some areas. Areas covered Here, we discuss whether synergizing effective measles therapeutics with vaccination could contribute to solving an endgame conundrum of measles elimination by accelerating the eradication effort. Based on an anticipated use for protection of high-risk contacts of confirmed measles cases through post-exposure prophylaxis, we identify key elements of the desirable drug profile, review current disease management strategies and the state of experimental inhibitor candidates, evaluate the risk associated with viral escape from inhibition, and consider the potential of measles therapeutics for the management of persistent viral infection of the CNS. Assuming a post-measles world with waning measles immunity, we contemplate the possible impact of therapeutics on controlling the threat imposed by closely related zoonotic pathogens of the same genus as measles virus. Expert opinion Efficacious therapeutics given for post-exposure prophylaxis of high-risk social contacts of confirmed index cases may aid measles eradication by closing herd immunity gaps due to vaccine refusal or failure in populations with overall good vaccination coverage. The envisioned primarily prophylactic application of measles therapeutics to a predominantly pediatric and/or adolescent patient population dictates the drug profile; the article must be safe and efficacious, orally available, shelf-stable at ambient temperature, and amenable to cost-effective manufacture

2014-12-01

Methylphenidate (MPD) is clinically effective in treating the symptoms of attention-deficit hyperactivity disorder; however, its relatively widespread availability has raised public health concerns on nonmedical use of MPD among certain adult populations. Most preclinical studies investigate whether presumed therapeutically relevant doses of MPD alter sensitivity to the reinforcing effects of other drugs, but it remains unclear whether doses of MPD likely exceeding therapeutic relevance impact the subsequent reinforcing effects of drugs. To begin to address this question, the effect of prior MPD self-administration (0.56 mg/kg/infusion) on the subsequent reinforcing effects of methamphetamine (METH, 0.032 or 0.1 mg/kg/infusion) was investigated in male Sprague-Dawley rats. For comparison, it was also determined whether prior experimenter-administered MPD, injected daily at a presumed therapeutically relevant dose (2 mg/kg), altered the subsequent reinforcing effects of METH. Results indicated that, under the current conditions, only a history of MPD self-administration increased sensitivity to the subsequent reinforcing effects of METH. Furthermore, MPD did not impact food-maintained responding, suggesting that the effect of MPD might be specific to drug reinforcers. These data suggest that short-term, nonmedical use of MPD might alter the positive reinforcing effects of METH in a manner relevant to vulnerability to drug use in humans.

Bone Marrow-Derived Cells as a Therapeutic Approach to Optic Nerve Diseases

Directory of Open Access Journals (Sweden)

Louise A. Mesentier-Louro

2016-01-01

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

2011-01-01

Regulatory and market developments have transformed the way in which UK private sector pension schemes operate. This has increased demands on trustees and advisors and the trusteeship governance model must evolve in order to remain fit for purpose. This volume brings together leading practitioners to provide an overview of what today constitutes good governance for pension schemes, from both a legal and a practical perspective. It provides the reader with an appreciation of the distinctive characteristics of UK occupational pension schemes, how they sit within the capital markets and their social and fiduciary responsibilities. Providing a holistic analysis of pension risk, both from the trustee and the corporate perspective, the essays cover the crucial role of the employer covenant, financing and investment risk, developments in longevity risk hedging and insurance de-risking, and best practice scheme administration.

Current issues of RNAi therapeutics delivery and development.

Science.gov (United States)

Haussecker, D

2014-12-10

the applications of RNAi therapeutics are rather limited. This is largely based on the observation that the biodistribution of RNAi formulations is typically more limited compared to small molecules and oral administration is not possible with current technologies. Similarly, the utility of a given RNAi formulation is limited to a few cell types and tissues at most and a universal delivery strategy should remain elusive for the foreseeable future. Therefore, to further expand on the therapeutic utility and patient convenience of RNAi, it is important to overcome a number of delivery-related technical and scientific challenges which will be discussed in this presentation. For systemic applications, these include the necessity for extended blood circulation times, vascular escape (probably the most rewarding inquiry currently), tissue penetration, cellular uptake, and escape into the cytoplasm. In terms of safety, it is important that these formulations do not accumulate in the body, do not cause excessive off-targeting due to 'chemical stickiness' (often useful for purposes of biodistribution), and overcome the physical/biological barriers in a controlled manner. The time for realizing the therapeutic potential of RNAi has come. At the same time, it is important to lay the foundations for the next leg of value creation by overcoming the challenges of delivering RNAi to new cell types. Based on results from exploratory research, the renewed interest in RNAi therapeutics and capital infusion, there is a reason to be optimistic that this can be achieved.

The Progress of Therapeutic Vaccination with Regard to Tuberculosis.

Science.gov (United States)

Cardona, Pere-Joan

2016-01-01

A major problem with tuberculosis (TB) control is the long duration of drug therapy-both for latent and for active TB. Therapeutic vaccination has been postulated to improve this situation, and to this end there are several candidates already in clinical phases of development. These candidates follow two main designs, namely bacilli-directed therapy based on inactivated -whole or -fragmented bacillus ( Mycobacterium w and RUTI) or fusion proteins that integrate non-replicating bacilli -related antigens (H56 vaccine), and host-directed therapy to reduce the tissue destruction. The administration of inactivated Mycobacterium vaccae prevents the "Koch phenomenon" response, and oral administration of heat-killed Mycobacterium manresensis prevents excessive neutrophilic infiltration of the lesions. This review also tries to explain the success of Mycobacterium tuberculosis by reviewing its evolution from infection to disease, and highlights the lack of a definitive understanding of the natural history of TB pathology and the need to improve our knowledge on TB immunology and pathogenesis.

Formulary decision-making about cephalosporins with similar therapeutic uses.

Science.gov (United States)

Mabe, Don M

2003-05-15

The various costs and intangible factors that enter into formulary decisions in an era of increasingly frequent drug product shortages that can adversely affect patient care and increase treatment costs are described. Pharmacy administration at Carolinas HealthCare System analyzed the costs associated with making a formulary switch from the third-generation cephalosporin ceftriaxone to cefotaxime, which recently became available in generic form and has a similar spectrum of antimicrobial activity and therapeutic uses. Hard dollar costs for purchasing drugs and the supplies needed to administer them; soft dollar costs for staff time spent acquiring, preparing, and administering doses; and intangible factors were considered. A reliable supply of drug product from the manufacturer was an important intangible factor because of frequent drug shortages in the past few years and the adverse effect on patient care and the increased soft dollar costs associated with these shortages. Administrators at Carolinas HealthCare System decided not to make the proposed formulary change after weighing the many factors and costs.

2016-05-20

Oligonucleotides present a high therapeutic potential for a wide variety of diseases. However, their clinical development is limited by their degradation by nucleases and their poor blood circulation time. Depending on the administration mode and the cellular target, these macromolecules will have to cross the vascular endothelium, to diffuse through the extracellular matrix, to be transported through the cell membrane, and finally to reach the cytoplasm. To overcome these physiological barriers, many strategies have been developed. Here, we review different methods of DNA vectorization, discuss limitations and advantages of the various vectors, and provide new perspectives for future development.

Therapeutic angiogenesis remains the most effective method to re-establish a proper blood flow in ischemic tissues. There is a great clinical need to identify an injectable format to achieve a well accumulation following local administration and a sustained delivery of biological factors at the ischemic sites. In the current study, fragmented nanofibers with loaded traditional Chinese medicines, astragaloside IV (AT), the main active ingredient of astragalus, and ferulic acid (FA), the main ingredient of angelica, were proposed to promote the microvessel formation after intramuscular injection into ischemic hindlimbs. Fragmented fibers with average lengths of 5 (FF-5), 20 (FF-20) and 80 μm (FF-80) were constructed by the cryocutting of aligned electrospun fibers. Their dispersion in sodium alginate solution (0.2%) indicated good injectability. After injection into the quadriceps muscles of the hindlimbs, FF-20 and FF-80 fiber fragments showed higher tissue retentions than FF-5, and around 90% of the injected doses were determined after 7 days. On a hindlimb ischemia model established by ligating the femoral arteries, intramuscular injection of the mixtures of FA-loaded and AT-loaded FF-20 fiber fragments substantially reduced the muscle degeneration with minimal fibrosis formation, significantly enhanced the neovessel formation and hindlimb perfusion in the ischemic tissues, and efficiently promoted the limb salvage with few limb losses. Along with the easy manipulation and lower invasiveness for in vivo administration, fragmented fibers should become potential drug carriers for disease treatment, wound recovery and tissue repair after local injection.

Market failure as ignored determinant of the choice between public and business administration

Directory of Open Access Journals (Sweden)

Gaylord George Candler

Full Text Available Abstract In the epistemology of administrative science, one of many important dimensions has been the different subfields of the study of administration. Perhaps the biggest, longest running ‘turf’ battle between these different areas of administrative knowledge is that between public and business administration. This is a controversy that goes back at least to Adam Smith, with his specific limitation of the role of ‘the sovereign’ (government, or public administration to justice, defense, and public works. In limiting government to these areas, note that Smith was also implicitly asserting that these were market, or ‘invisible hand’ failures: areas where the pursuit of self-interest would not yield the good of society, the specific moral justification Smith identified for market exchange. Contemporary discussions of the relative role of market and state are generally framed in terms of the role of the State, with market provision the default option. We will argue that even discussions of the role of the State can best be assessed through the concept of market failure. The nine broad types of market failure discussed include institutions, public goods, monopoly, asymmetric information, externalities, substantive issues, principal/agent problems, irrationality, and the implications of ‘creative destruction’.

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)

The aims of this study were to make the lung cancer clinics in Korea Cancer Center Hospital, and to establish new therapeutic methods of lung cancer for increasing the cure rate and survival rate of patients. Also another purpose of this study was to establish a common treatment method in our hospital. All patients who were operated in Korea Cancer Center Hospital from 1987 due to lung cancer were followed up and evaluated. And we have been studied the effect of postoperative adjuvant therapy in stage I, II, IIIA non-small cell lung cancer patients from 1989 with the phase three study form. Follow-up examinations were scheduled in these patients and interim analysis was made. Also we have been studied the effect of chemo-therapeutic agents in small cell lung cancer patients from 1997 with the phase two study form. We evaluated the results of this study. Some important results of this study were as follows. 1. The new therapeutic method (surgery + MVP chemotherapy) was superior to the standard therapeutic one in stage I Non-small cell lung cancer patients. So, we have to change the standard method of treatment in stage I NSCLC. 2. Also, this new therapeutic method made a good result in stage II NSCLC patients. And this result was reported in The Annals of Thoracic Surgery. 3. However, this new therapeutic method was not superior to the standard treatment method (surgery only) in stage IIIA NSCLC patients. So, we must develop new chemo-therapeutic agents in the future for advanced NSCLC patients. 4. In the results of the randomized phase II studies about small cell lung cancer, there was no difference in survival between Etoposide + Carboplatin + Ifosfamide + Cisplatin group and Etoposide + Carboplatin + Ifosfamide + Cisplatin + Tamoxifen group in both the limited and extended types of small cell lung cancer patients

Brown, Joshua D; Morey, Leslie C

2016-01-01

This case illustrates the utility of incorporating therapeutic assessment in a triage context that typically involves a focus on gathering information. A man referred to our clinic by a local mental health center was seen by our assessment team for a triage that includes the administration of a single psychological test, the Personality Assessment Inventory (PAI). Although this triage must rapidly gather information to determine client suitability and treatment assignment, we still attempt to work with clients to collaboratively develop goals for this assessment that include addressing questions that are central concerns for the clients. In this case, the test results suggested a severe disorder that accounted for many phenomena that he had been experiencing but had apparently been reluctant to share. The information gathered led to a referral to a different treatment program that could provide pharmacological and more intensive forms of treatment. However, the collaborative bond formed between the assessor and the client during this triage was sufficiently strong that it was our assessor to whom the client turned in a subsequent crisis precipitated by a symptomatic exacerbation. This case illustrates complementary information gathering and therapeutic goals of assessment even in the context of a brief assessment.

Mesenchymal Stem Cells as New Therapeutic Agents for the Treatment of Primary Biliary Cholangitis

Directory of Open Access Journals (Sweden)

Aleksandar Arsenijevic

2017-01-01

Full Text Available Primary biliary cholangitis (PBC is a chronic autoimmune cholestatic liver disease characterized by the progressive destruction of small- and medium-sized intrahepatic bile ducts with resultant cholestasis and progressive fibrosis. Ursodeoxycholic acid and obethicholic acid are the only agents approved by the US Food and Drug Administration (FDA for the treatment of PBC. However, for patients with advanced, end-stage PBC, liver transplantation is still the most effective treatment. Accordingly, the alternative approaches, such as mesenchymal stem cell (MSC transplantation, have been suggested as an effective alternative therapy for these patients. Due to their immunomodulatory characteristics, MSCs are considered as promising therapeutic agents for the therapy of autoimmune liver diseases, including PBC. In this review, we have summarized the therapeutic potential of MSCs for the treatment of these diseases, emphasizing molecular and cellular mechanisms responsible for MSC-based effects in an animal model of PBC and therapeutic potential observed in recently conducted clinical trials. We have also presented several outstanding problems including safety issues regarding unwanted differentiation of transplanted MSCs which limit their therapeutic use. Efficient and safe MSC-based therapy for PBC remains a challenging issue that requires continuous cooperation between clinicians, researchers, and patients.

In order to enhance the therapeutic efficacy of praziquantel (PZQ against tapeworm, PZQ-loaded hydrogenated castor oil solid lipid nanoparticle (PZQ-HCO-SLN suspension was prepared by a hot homogenization and ultrasonication method. The stability of the suspension at 4°C and room temperature was evaluated by the physicochemical characteristics of the nanoparticles and in-vitro release pattern of the suspension. Pharmacokinetics was studied after subcutaneous administration of the suspension in dogs. The therapeutic effect of the novel formulation was evaluated in dogs naturally infected with Echinococcus granulosus. The results showed that the drug recovery of the suspension was 97.59% ± 7.56%. Nanoparticle diameter, polydispersivity index, and zeta potential were 263.00 ± 11.15 nm, 0.34 ± 0.06, and -11.57 ± 1.12 mV, respectively and showed no significant changes after 4 months of storage at both 4°C and room temperature. The stored suspensions displayed similar in-vitro release patterns as that of the newly prepared one. SLNs increased the bioavailability of PZQ 5.67-fold and extended the mean residence time of the drug from 56.71 to 280.38 hours. Single subcutaneous administration of PZQ-HCO-SLN suspension obtained enhanced therapeutic efficacy against tapeworm in infected dogs. At the dose of 5 mg/kg, the stool-ova reduction and negative conversion rates and tapeworm removal rate of the suspension were 100%, while the native PZQ were 91

Chronic Uridine Administration Induces Fatty Liver and Pre-Diabetic Conditions in Mice.

Directory of Open Access Journals (Sweden)

Yasuyo Urasaki

Full Text Available Uridine is a pyrimidine nucleoside that exerts restorative functions in tissues under stress. Short-term co-administration of uridine with multiple unrelated drugs prevents drug-induced liver lipid accumulation. Uridine has the ability to modulate liver metabolism; however, the precise mechanism has not been delineated. In this study, long-term effects of uridine on liver metabolism were examined in both HepG2 cell cultures and C57BL/6J mice. We report that uridine administration was associated with O-GlcNAc modification of FOXO1, increased gluconeogenesis, reduced insulin signaling activity, and reduced expression of a liver-specific fatty acid binding protein FABP1. Long-term uridine feeding induced systemic glucose intolerance and severe liver lipid accumulation in mice. Our findings suggest that the therapeutic potentials of uridine should be designed for short-term acute administration.

To compare the differences in the clinical therapeutic effects on reflux esophagitis among the combined therapy of huazhuo jiedu jiangni decoction (the decoction for resolving the turbid, detoxification and reducing the pathologic upward qi in short) and acupuncture, omeprazole and Chinese herbal medicine. 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).

The effect of enrofloxacin on cytokine secretion by porcine peripheral blood mononuclear cells (PBMCs) was studied. Twenty 8-20-week-old pigs were randomly divided into two groups: control (C, n = 10) and experimental (E, n = 10) were used. Pigs from group E received enrofloxacin at therapeutic dose for 5 consecutive days. Blood samples were collected at 0 (before antibiotic administration), 2, 4 (during antibiotic therapy) 6, 9, 14 21, 35, 49, and 63 d of study (after treatment). PBMCs of pigs from both groups were incubated with or without lipopolysaccharide (LPS). Ex vivo production on interleukin (IL)-4, IL-6, IL-10, INF-γ, and TNF-α were analyzed using ELISA assay. Intramuscular administration of enrofloxacin to healthy pigs for 5 consecutive days induced a transitory reduction of the ex vivo response of PBMCs to LPS in terms of IL-6 and TNF-α secretion. The level of IL-6 returned to day 0 level shortly after end of treatment, while the TNF-α production remained reduced 10 d after the end of treatment. Our results indicate that enrofloxacin given in vivo in therapeutic doses has an immunomodulatory effect through its capacity to inhibit ex vivo secretion of IL-6 and TNF-α by porcine PBMC after LPS stimulation.

Full Text Available Context: It has been well-established now that intravenous (IV tranexamic acid (TXA is a potent agent to control postoperative blood loss following total knee arthroplasty (TKA. Recently, intraarticular administration of this agent has also shown good efficacy for the same. Aims: Comparison of postoperative blood loss between IV and topical administration of TXA in TKAs. Materials and Design: Eighty-six TKAs on knees were included in this study. Randomization was done so that 40 TKA received 1 g of IV TXA, while 46 had intraarticular administration of 1 g TXA. Subjets and Methods: We compared the postoperative blood loss by calculating the difference in pre- and postop hemoglobin and need for blood transfusion. Functional assessment was done on basis of Western Ontario McMaster Osteo-Arthritis Index (WOMAC scores and complications like postoperative infection, oozing from the wound site and thromboembolic manifestations. Results: Blood loss was significantly less in the intraarticular administration group as compared to the IV injection group. Total blood loss, blood transfusion group, and drain output was also less but the difference was not significant. The functional assessment (WOMAC scores were equivocal and so were the complications including thromboembolic manifestations (two cases each of deep vein thrombosis (DVT and no cases of pulmonary embolism (PE. Conclusion: Intraarticular administration of TXA to prevent postoperative blood loss in TKA is a safe and effective alternative/adjunct to its IV administration.

Vogl, T.J.; Mueller, P.K.; Mack, M.G.; Straub, R.; Engelmann, K.; Neuhaus, P.

The liver is the most common site of metastatic tumour deposits. Hepatic metastases are the major cause of morbidity and mortality in patients with gastrointestinal carcinomas and other malignant tumours. The rationale and results for interventional therapeutic techniques in the treatment of liver metastases are presented. For the treatment of patients with irresectable liver metastases, alternative local ablative therapeutic modalities have been developed. Technique and results of local interventional therapies are presented such as microwave-, radiofrequency (RF)- and ultrasound ablation, and laser-induced interstitial therapy (LITT), cryotherapy and local drug administration such as alcohol injection, endotumoral chemotherapy and regional chemoembolisation. In addition to cryotherapy, all ablative techniques can be performed percutaneously with low morbidity and mortality. Cryotherapy is an effective and precise technique for inducing tumour necrosis, but it is currently performed via laparotomy. Percutaneous local alcohol injection results in an inhomogeneous distribution in liver metastases with unreliable control rates. Local chemotherapeutic drug instillation and regional chemoembolisation produces relevant but non-reproducible lesions. Laser-induced interstitial thermotherapy (LITT) performed under MRI guidance results in precise and reproducible areas of induced necrosis with a local control of 94 %, and with an improved survival rate. Interventional therapeutic techniques of liver metastases do result in a remarkable local tumour control rate with improved survival results. (orig.)

We report a prospective and descriptive study about childhood acute poisoning with kerosene in Djibouti. Acute poisoning is a common and stable occurrence in low socioeconomic groups in Africa, where negligence is the main cause of poisoning. The respiratory system was the main target, with 41% of patients having pneumonia, which may become life-threatening, but with low mortality rate. Asymptomatic patients (35%) can be discharged, while those with pulmonary or neurological signs must be admitted for observation and supportive treatment based on oxygen administration. Our study suggests management and provides a discussion for therapeutic options and emphasizes the importance of prevention.

Therapeutic neuroprotective agents for amyotrophic lateral sclerosis

Pandya, Rachna S.; Zhu, Haining; Li, Wei; Bowser, Robert; Friedlander, Robert M.

2014-01-01

Amyotrophic lateral sclerosis (ALS) is a fatal chronic neurodegenerative disease whose hallmark is proteinaceous, ubiquitinated, cytoplasmic inclusions in motor neurons and surrounding cells. Multiple mechanisms proposed as responsible for ALS pathogenesis include dysfunction of protein degradation, glutamate excitotoxicity, mitochondrial dysfunction, apoptosis, oxidative stress, and inflammation. It is therefore essential to gain a better understanding of the underlying disease etiology and search for neuroprotective agents that might delay disease onset, slow progression, prolong survival, and ultimately reduce the burden of disease. Because riluzole, the only Food and Drug Administration (FDA)-approved treatment, prolongs the ALS patient’s life by only 3 months, new therapeutic agents are urgently needed. In this review, we focus on studies of various small pharmacological compounds targeting the proposed pathogenic mechanisms of ALS and discuss their impact on disease progression. PMID:23864030

It has previously been shown that the consumption of probiotics may have beneficial effects not only on peripheral tissues but also on the central nervous system and behavior via the microbiota-gut-brain axis, raising the possibility that treatment with probiotics could be an effective therapeutic strategy for managing neurodegenerative disorders. In this study, we investigated the effects of oral administration of Bifidobacterium breve strain A1 (B. breve A1) on behavior and physiological processes in Alzheimer's disease (AD) model mice. We found that administration of B. breve A1 to AD mice reversed the impairment of alternation behavior in a Y maze test and the reduced latency time in a passive avoidance test, indicating that it prevented cognitive dysfunction. We also demonstrated that non-viable components of the bacterium or its metabolite acetate partially ameliorated the cognitive decline observed in AD mice. Gene profiling analysis revealed that the consumption of B. breve A1 suppressed the hippocampal expressions of inflammation and immune-reactive genes that are induced by amyloid-β. Together, these findings suggest that B. breve A1 has therapeutic potential for preventing cognitive impairment in AD.

This study was conducted to analyze patients' knowledge about therapeutic goals for diabetic patients and factors associated with good knowledge. A total of 266 diabetic patients were randomly selected from 6 diabetes clinics in Kuwait to be included in a cross-sectional patient survey. Data were collected via face-to-face structured interviews using a pretested questionnaire. Descriptive and logistic regression analysis was used in data analysis. The response rate was 93% (n = 247). The percentages [95% confidence interval (CI)] of patients who reported knowing their recent levels of low-density lipoprotein cholesterol (LDL-C), blood pressure (BP), and glycosylated hemoglobin (HbA1c) were 5% (2-8), 54% (48-60), and 8% (5-11), respectively. The percentages (95% CI) of patients who admitted knowing the target goals for LDL-C, BP, HbA1c, fasting, and postprandial blood glucose levels were 3% (1-6), 49% (43-55), 6% (3-9), 62% (56-68) and 55% (49-61), respectively. Correct target goals for LDL-C, BP, HbA1c, fasting, and postprandial blood glucose levels were reported by 2% (1-4), 43% (37-49), 5% (2-8), 60% (54-66), and 47% (41-53), respectively. Those with a high education (OR = 4.76; 95% CI 2.34-9.68) and those with a family history of diabetes (OR = 3.05; 95% CI 1.50-6.19) had good knowledge about correct targets. The current findings revealed that lack of knowledge about recent levels of BP, LDL-C and HbA1c and therapeutic goals was alarmingly high, which highlights the need for the implementation of an effective multidisciplinary team approach to encourage patient education and self-care.

Psychomotor Retardation in Depression: A Systematic Review of Diagnostic, Pathophysiologic, and Therapeutic Implications

Directory of Open Access Journals (Sweden)

Djamila Bennabi

2013-01-01

Full Text Available Psychomotor retardation is a central feature of depression which includes motor and cognitive impairments. Effective management may be useful to improve the classification of depressive subtypes and treatment selection, as well as prediction of outcome in patients with depression. The aim of this paper was to review the current status of knowledge regarding psychomotor retardation in depression, in order to clarify its role in the diagnostic management of mood disorders. Retardation modifies all the actions of the individual, including motility, mental activity, and speech. Objective assessments can highlight the diagnostic importance of psychomotor retardation, especially in melancholic and bipolar depression. Psychomotor retardation is also related to depression severity and therapeutic change and could be considered a good criterion for the prediction of therapeutic effect. The neurobiological process underlying the inhibition of activity includes functional deficits in the prefrontal cortex and abnormalities in dopamine neurotransmission. Future investigations of psychomotor retardation should help improve the understanding of the pathophysiological mechanisms underlying mood disorders and contribute to improving their therapeutic management.

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

Full Text Available Background/Aims: The reliability of diagnostic coding of acute stroke and transient ischemic attack (TIA in administrative data is uncertain. The purpose of this study is to determine the agreement between administrative data sources and chart audit for the identification of stroke type, stroke risk factors, and the use of hospital-based diagnostic procedures in patients with stroke or TIA. Methods: Medical charts for a population-based sample of patients (n = 14,508 with ischemic stroke, intracerebral hemorrhage (ICH, or TIA discharged from inpatient and emergency departments (ED in Ontario, Canada, between April 1, 2012 and March 31, 2013, were audited by trained abstractors. Audited data were linked and compared with hospital administrative data and physician billing data. The positive predictive value (PPV of hospital administrative data and kappa agreement for the reporting of stroke type were calculated. Kappa agreement was also determined for stroke risk factors and for select stroke-related procedures. Results: The PPV for stroke type in inpatient administrative data ranged from 89.5% (95% CI 88.0-91.0 for TIA, 91.9% (95% CI 90.2-93.5 for ICH, and 97.3% (95% CI 96.9-97.7 for ischemic stroke. For ED administrative data, PPV varied from 78.8% (95% CI 76.3-81.2 for ischemic, 86.3% (95% CI 76.8-95.7 for ICH, and 95.3% (95% CI 94.6-96.0 for TIA. The chance-corrected agreement between the audited and administrative data was good for atrial fibrillation (k = 0.60 and very good for diabetes (k = 0.86. Hospital administrative data combined with physician billing data more than doubled the observed agreement for carotid imaging (k = 0.65 and echocardiography (k = 0.66 compared to hospital administrative data alone. Conclusions: Inpatient and ED administrative data were found to be reliable in the reporting of the International Classification of Diagnosis, 10th revision, Canada (ICD-10-CA-coded ischemic stroke, ICH and TIA, and for the recording of

Botulinum toxins (BoNTs) are produced by several anaerobic species of the genus Clostridium and, although they were originally considered lethal toxins, today they find their usefulness in the treatment of a wide range of pathologies in various medical specialties. Botulinum neurotoxin has been identified in seven different isoforms (BoNT-A, BoNT-B, BoNT-C, BoNT-D, BoNT-E, BoNT-F, and BoNT-G). Neurotoxigenic Clostridia can produce more than 40 different BoNT subtypes and, recently, a new BoNT serotype (BoNT-X) has been reported in some studies. BoNT-X has not been shown to actually be an active neurotoxin despite its catalytically active LC, so it should be described as a putative eighth serotype. The mechanism of action of the serotypes is similar: they inhibit the release of acetylcholine from the nerve endings but their therapeutically potency varies. Botulinum toxin type A (BoNT-A) is the most studied serotype for therapeutic purposes. Regarding the gynecological pathology, a series of studies based on the efficiency of its use in the treatment of refractory myofascial pelvic pain, vaginism, dyspareunia, vulvodynia and overactive bladder or urinary incontinence have been reported. The current study is a review of the literature regarding the efficiency of BoNT-A in the gynecological pathology and on the long and short-term effects of its administration.

The therapeutic success of Boron Neutron Capture Therapy (BNCT) depends centrally on boron concentration in tumor and healthy tissue. We previously demonstrated the therapeutic efficacy of boronophenylalanine (BPA) and sodium decahydrodecaborate (GB-10) as boron carriers for BNCT in the hamster cheek pouch oral cancer model. Given the clinical relevance of sodium mercaptoundecahydro-closo-dodecaborate (BSH) as a boron carrier, the aim of the present study was to expand the ongoing BSH biodistribution studies in the hamster cheek pouch oral cancer model. In particular, we studied 3 additional post-administration time-points and increased the sample size corresponding to the time-points evaluated previously, to select more accurately the post-administration time at which neutron irradiation would potentially confer the greatest therapeutic advantage. BSH was dissolved in saline solution in anaerobic conditions to avoid the formation of the dimer BSSB and its oxides which are toxic. The solution was injected intravenously at a dose of 50 mg 10 B/kg (88 mg BSH / kg). Different groups of animals were killed humanely at 7, 8, and 10 h after administration of BSH. The sample size corresponding to the time-points 3, 4, 6, 9 and 12 h was increased. Samples of blood, tumor, precancerous tissue, normal pouch tissue, cheek mucosa, parotid gland, palate, skin, tongue, spinal cord marrow, brain, liver, kidney, spleen and lung were processed for boron measurement by Optic Emission Spectroscopy (ICP-OES). Boron concentration in tumor peaked to 24-34 ppm, 3-10 h post-administration of BSH, with a spread in values that resembled that previously reported in other experimental models and human subjects. The boron concentration ratios tumor/normal pouch tissue and tumor/blood ranged from 1.3 to 1.8. No selective tumor uptake was observed at any of the time points evaluated. The times post-administration of BSH that would be therapeutically most useful would be 5, 7 and 9 h. The

Therapeutic Use of Cannabis in Inflammatory Bowel Disease

Katz, Seymour

2016-01-01

The marijuana plant Cannabis sativa and its derivatives, cannabinoids, have grown increasingly popular as a potential therapy for inflammatory bowel disease (IBD). Studies have shown that modulation of the endocannabinoid system, which regulates various functions in the body and has been shown to play a key role in the pathogenesis of IBD, has a therapeutic effect in mouse colitis. Epidemiologic data and human therapy studies reveal a possible role for cannabinoids in the symptomatic treatment of IBD, although it has yet to be determined in human populations whether cannabinoids have therapeutic anti-inflammatory effects in IBD or are simply masking its many debilitating symptoms. Large, double-blind, randomized, placebo-controlled trials using serial inflammatory markers, biopsy findings, and endoscopic disease severity to demonstrate objective improvement in IBD are necessary before cannabis can be empirically accepted and recommended as an IBD treatment option. Questions concerning its safety profile and adverse effects prompt the need for further research, particularly in regard to dosing and route of administration to maximize benefits and limit potential harms. Cannabis use should be reserved for symptomatic control in patients with severe IBD refractory to the currently available standard-of-care and complementary and alternative medicines. PMID:28035196

Gap junctions and hemichannels composed of connexins: potential therapeutic targets for neurodegenerative diseases

Directory of Open Access Journals (Sweden)

Hideyuki eTakeuchi

2014-09-01

Full Text Available Microglia are macrophage-like resident immune cells that contribute to the maintenance of homeostasis in the central nervous system (CNS. Abnormal activation of microglia can cause damage in the CNS, and accumulation of activated microglia is a characteristic pathological observation in neurologic conditions such as trauma, stroke, inflammation, epilepsy, and neurodegenerative diseases. Activated microglia secrete high levels of glutamate, which damages CNS cells and has been implicated as a major cause of neurodegeneration in these conditions. Glutamate-receptor blockers and microglia inhibitors (e.g. minocycline have been examined as therapeutic candidates for several neurodegenerative diseases; however, these compounds exerted little therapeutic benefit because they either perturbed physiological glutamate signals or suppressed the actions of protective microglia. The ideal therapeutic approach would hamper the deleterious roles of activated microglia without diminishing their protective effects. We recently found that abnormally activated microglia secrete glutamate via gap-junction hemichannels on the cell surface. Moreover, administration of gap-junction inhibitors significantly suppressed excessive microglial glutamate release and improved disease symptoms in animal models of neurologic conditions such as stroke, multiple sclerosis, amyotrophic lateral sclerosis, and Alzheimer’s disease. Recent evidence also suggests that neuronal and glial communication via gap junctions amplifies neuroinflammation and neurodegeneration. Elucidation of the precise pathologic roles of gap junctions and hemichannels may lead to a novel therapeutic strategies that can slow and halt the progression of neurodegenerative diseases.

Intravenous access procedures in children are considered to be one of the most stressful because it is invasive, and the use of needles generates anxiety, insecurity, and fear. Playful strategies using dolls and even the materials used for venipuncture can assist children in understanding, accepting, and coping with the procedure. Field research was developed on the applicability of the therapeutic toy in the preparation of preschool children for venipuncture procedure based on the protocol developed by Martins, Ribeiro, Borba, and Silva (2001) and Kiche and Almeida (2009). The study was done in a private hospital in Greater São Paulo, Brazil, with 10 children ages 3 to 6 years. Data were gathered through observation and questionnaires completed by the children's adult guardians. Before the activity, the children showed fearful facial expressions, used monosyllabic responses, and avoided looking at the health care professional. After the strategy of using therapeutic toy dolls and puppets, 40% of the children calmly accepted the venipuncture procedure, and 100% showed a change to their initial negative reaction, became more communicative and cooperative, and participated and interacted with researchers, even after the end of the activity and procedure. The strategy of therapeutic toys helps make an unfamiliar environment, strangers, and a procedure characterized as painful and difficult less stressful. Pediatric nurses are in a good position to use this resource to offer more humanized care to children.

Radiological protection guidance for radioactive patients -new data for therapeutic 131I

Hilditch, T.E.; Watson, W.S.; Connell, J.M.C.; Davies, D.L.; Alexander, W.D.

1991-01-01

Thyroidal retention of 131 I was measured in 77 thyrotoxic patients over a period of 1-50 days after a first therapeutic administration of the radionuclide. Mean 131 I activity in the gland (± S.D.) at 1 day was 56.1 ± 11.1% of the administered dose activity and thereafter retention followed a single exponential decay pattern with a mean effective half-life (± S.E.M.) of 6.35 ± 0.14 days. In patients who required further 131 I therapy, there was evidence that retention could be markedly reduced if there was virtual ablation of thyroid tissue. It is proposed that these retention data can be used to determine body radioactivity at any interval after the administration of 131 I for treatment of thyrotoxicosis, thus obviating the need for serial measurements in every individual patient.

Enzyme replacement has been under consideration as a therapeutic strategy for patients with Gaucher disease for more than two decades. Previous studies indicated that single injections of purified glucocerebrosidase reduced the amount of storage material in the liver. It was important to determine whether administration of exogenous enzyme on a regular basis would be of clinical benefit. The authors weekly i.v. infusions of a macrophage-targeted preparation of human placental glucocerebrosidase in a child with type 1 Gaucher disease increased hemoglobin over a 20-week period. The platelet count also increased. Phagocytic activity in the spleen decreased during the period of enzyme administration, and there was radiographic evidence of skeletal improvement. These observations document objective clinical responses to enzyme supplementation in a patient with a sphingolipid storage disorder

2012-01-01

Silk fibroin (SF) is a biopolymer with distinguishing features from many other bio- as well as synthetic polymers. From a biomechanical and drug delivery perspective, SF combines remarkable versatility for scaffolding (solid implants, hydrogels, threads, solutions), with advanced mechanical properties and good stabilization and controlled delivery of entrapped protein and small molecule drugs, respectively. It is this combination of mechanical and pharmaceutical features which render SF so exciting for biomedical applications. his pattern along with the versatility of this biopolymer have been translated into progress for musculoskeletal applications. We review the use and potential of silk fibroin for systemic and localized delivery of therapeutics in diseases affecting the musculoskeletal system. We also present future directions for this biopolymer as well as the necessary research and development steps for their achievement. PMID:22522139

To determine the pharmacokinetics of tramadol hydrochloride (30 mg/kg) following twice-daily oral administration in Hispaniolan Amazon parrots (Amazona ventralis). 9 healthy adult Hispaniolan Amazon parrots. Tramadol hydrochloride was administered to each parrot at a dosage of 30 mg/kg, PO, every 12 hours for 5 days. Blood samples were collected just prior to dose 2 on the first day of administration (day 1) and 5 minutes before and 10, 20, 30, 60, 90, 180, 360, and 720 minutes after the morning dose was given on day 5. Plasma was harvested from blood samples and analyzed by high-performance liquid chromatography. Degree of sedation was evaluated in each parrot throughout the study. No changes in the parrots' behavior were observed. Twelve hours after the first dose was administered, mean ± SD concentrations of tramadol and its only active metabolite M1 (O-desmethyltramadol) were 53 ± 57 ng/mL and 6 ± 6 ng/mL, respectively. At steady state following 4.5 days of twice-daily administration, the mean half-lives for plasma tramadol and M1 concentrations were 2.92 ± 0.78 hours and 2.14 ± 0.07 hours, respectively. On day 5 of tramadol administration, plasma concentrations remained in the therapeutic range for approximately 6 hours. Other tramadol metabolites (M2, M4, and M5) were also present. On the basis of these results and modeling of the data, tramadol at a dosage of 30 mg/kg, PO, will likely need to be administered every 6 to 8 hours to maintain therapeutic plasma concentrations in Hispaniolan Amazon parrots.

We applied HSV-tk/GCV strategy to orthotopic rat hepatoma model and showed anticancer effects of hepatoma. The increased expression of Lac Z gene after adenovirus-mediated gene delivery throughout hepatic artery was thought that is increased the possibility of gene therapy for curing hepatoma. With the construction of kGLP-laboratory, it is possible to produce a good quantity and quality of adenovirus in lage-scale production and purification of adenovirus vector. Also, the analysis of hepatoma related genes by PCR-LOH could be used for the diagnosis of patients and the development of therapeutic gene.

The effects of activated charcoal (AC) mixed with cathartics for gastric decontamination in the management of organophosphate (OP) poisoning remain unknown due to limited clinical evidence. This exploratory study assessed the effectiveness of premixed AC-sorbitol as a treatment for OP poisoning. This retrospective observational case study included patients who either did not receive AC-sorbitol or received a single dose of AC-sorbitol within 24 h after OP ingestion. The patients were divided into three groups: no AC-sorbitol treatment, patients who received AC-sorbitol within 1 h of OP ingestion, and patients who received AC-sorbitol more than 1 h after OP ingestion. Mortality, the development of respiratory failure, and the duration of mechanical ventilation were used as outcome measurements for effectiveness, whereas aspiration pneumonia and electrolyte imbalance were employed as safety measurements. Among 262 patients with OP poisoning, 198 were included. Of these, 133 patients did not receive AC-sorbitol, whereas 14 and 51 patients received AC-sorbitol within 1 h or more than 1 h after ingestion, respectively. The time from ingestion to hospital arrival and time from ingestion to administration of atropine and pralidoxime differed among the groups, whereas other characteristics, including age, amount ingested, and type of ingested OP, were similar among the groups. Univariate and multivariate analysis demonstrated that the administration of AC-sorbitol was not associated with outcome measures for effectiveness and did not significantly increase either aspiration pneumonia or electrolyte imbalances during hospitalization. The administration of AC-sorbitol exerted neither beneficial nor harmful effects on the outcomes of OP-poisoned patients regardless of the time from OP ingestion to administration, compared with those of patients who did not receive AC-sorbitol. However, this study enrolled a small number of patients who received AC-sorbitol; further qualified

The development and effectiveness of international administrative law on the occasion of the thirtieth anniversary of the World Bank Administrative Tribunal

CERN Document Server

2012-01-01

International administrative law, or more precisely the law of the international civil service, has been the focus of increased attention in recent years. A part of the discussion has focused on the design of the justice mechanisms of international organizations, exemplified by the overhaul of the internal justice system of the United Nations in 2009. The internal justice systems of some international organizations have been subjected to scrutiny before some national courts, and the role and contribution of international administrative tribunals to the development of the law continue to be an important part of discussions of good governance and accountability of international organizations. The essays in this book, written by judges, practitioners, academics and other experts, address these and other issues.

Software licenses: Good fences make good neighbors

The basis for a good contract is that it is beneficial to both parties. A good foundation will cement the responsibilities and obligations of the parties after areas of agreement have been negotiated. Unfortunately, software licenses do not always reflect what is best for all. Some clauses are definitely for the benefit of the vendor, while others are required by a prudent client. The resulting contract is then a matter of reasonable compromise to achieve a good business relationship. Major issues of warranty, liability, training, support, and payment may be in conflict. Such topics as maintenance, testing, patents, extent of use, and return of software are often overlooked or addressed unevenly. This paper addresses these subjects and provides guidelines for software licenses. An understanding of legal phrases is of value. A better understanding of the viewpoints of both the vendor and the client results in a better working relationship

Protein Adsorption to In-Line Filters of Intravenous Administration Sets.

2017-10-01

Ensuring compatibility of administered therapeutic proteins with intravenous administration sets is an important regulatory requirement. A low-dose recovery during administration of low protein concentrations is among the commonly observed incompatibilities, and it is mainly due to adsorption to in-line filters. To better understand this phenomenon, we studied the adsorption of 4 different therapeutic proteins (2 IgG1s, 1 IgG4, and 1 Fc fusion protein) diluted to 0.01 mg/mL in 5% glucose (B. Braun EcoFlac; B. Braun Melsungen AG, Melsungen, Germany) or 0.9% sodium chloride (NaCl; Freeflex; Fresenius Kabi, Friedberg, Germany) solutions to 8 in-line filters (5 positively charged and 3 neutral filters made of different polymers and by different suppliers). The results show certain patterns of protein adsorption, which depend to a large extent on the dilution solution and filter material, and to a much lower extent on the proteins' biophysical properties. Investigation of the filter membranes' zeta potential showed a correlation between the observed adsorption pattern in 5% glucose solution and the filter's surface charge, with higher protein adsorption for the strongly negatively charged membranes. In 0.9% NaCl solution, the surface charges are masked, leading to different adsorption patterns. These results contribute to the general understanding of the protein adsorption to IV infusion filters and allow the design of more efficient compatibility studies.

The heavy-element content of ink in ancient administrative documents makes it possible to detect the characters with different synchrotron imaging techniques, based on attenuation or refraction. This is the first step in the direction of non-interactive virtual X-ray reading. Handwritten characters in administrative antique documents from three centuries have been detected using different synchrotron X-ray imaging techniques. Heavy elements in ancient inks, present even for everyday administrative manuscripts as shown by X-ray fluorescence spectra, produce attenuation contrast. In most cases the image quality is good enough for tomography reconstruction in view of future applications to virtual page-by-page ‘reading’. When attenuation is too low, differential phase contrast imaging can reveal the characters from refractive index effects. The results are potentially important for new information harvesting strategies, for example from the huge Archivio di Stato collection, objective of the Venice Time Machine project

Full Text Available This study aimed at understanding the feelings experienced by the child with cancer manifested during Therapeutic Toy sessions. This qualitative research was performed with five children aged between three and twelve years, of both sexes. Data collection was carried out through a participatory and systematic observation, coupled with interviews intermediated by Therapeutic Toy Sessions. The data was worked using discourse analysis. The child with cancer was shown as a being full of feelings. The fear of death, pain, sadness on the limitations imposed by the disease, the withdrawal and rebellion with the procedures, the anguish in the face of uncertainties were negative feelings expressed by the children in the dramatizations. However, the development of treatment, the manifestation of a good prognosis and outcome of cure were emerging feelings of hope and happiness before the treatment, optimism in return to usual activities and overcoming amidst the difficulties experienced.

Is methane a new therapeutic gas?

Liu Wenwu

2012-09-01

Full Text Available Abstract Background Methane is an attractive fuel. Biologically, methanogens in the colon can use carbon dioxide and hydrogen to produce methane as a by-product. It was previously considered that methane is not utilized by humans. However, in a recent study, results demonstrated that methane could exert anti-inflammatory effects in a dog small intestinal ischemia-reperfusion model. Point of view Actually, the bioactivity of methane has been investigated in gastrointestinal diseases, but the exact mechanism underlying the anti-inflammatory effects is required to be further elucidated. Methane can cross the membrane and is easy to collect due to its abundance in natural gas. Although methane is flammable, saline rich in methane can be prepared for clinical use. These seem to be good news in application of methane as a therapeutic gas. Conclusion Several problems should be resolved before its wide application in clinical practice.

Real-Time Scintigraphic Assessment of Intravenous Radium-223 Administration for Quality Control

2015-01-01

Full Text Available Radium-223 (223Ra dichloride is an approved intravenous radiotherapy for patients with osseous metastases from castration-resistant prostate cancer (CRPC. In addition to the therapeutic alpha radiation, there is additional 223Ra radiation generated which produces photons that can be imaged with conventional gamma cameras. No studies have evaluated real-time and quality imaging during intravenous 223Ra administration to verify systemic circulation and exclude 223Ra extravasation at the injection site. A retrospective review was performed for fifteen 223Ra administrations for CRPC patients which were imaged using a large field of view portable gamma camera (LFOVPGC for the purposes of quality control and patient safety. Dynamic imaging of the chest was performed before, during, and after the 223Ra administration to verify systemic circulation, per institutional clinical protocol. Before and after 223Ra administration, a static image was obtained of the intravenous access site. Dynamic imaging of the chest confirmed systemic administration early during the 1-minute injection period for all patients. There were no cases of focal 223Ra extravasation at the site of intravenous access. These results verify that systemic 223Ra administrations can be quantified with real-time imaging using an LFOVPGC. This simple approach can confirm and quantify systemic circulation of 223Ra early during injection and exclude focal extravasation for the purposes of quality control.

The Human Experience With Ghrelin Administration

Garin, Margaret C.; Burns, Carrie M.; Kaul, Shailja

2013-01-01

Context: Ghrelin is an endogenous stimulator of GH and is implicated in a number of physiological processes. Clinical trials have been performed in a variety of patient populations, but there is no comprehensive review of the beneficial and adverse consequences of ghrelin administration to humans. Evidence Acquisition: PubMed was utilized, and the reference list of each article was screened. We included 121 published articles in which ghrelin was administered to humans. Evidence Synthesis: Ghrelin has been administered as an infusion or a bolus in a variety of doses to 1850 study participants, including healthy participants and patients with obesity, prior gastrectomy, cancer, pituitary disease, diabetes mellitus, eating disorders, and other conditions. There is strong evidence that ghrelin stimulates appetite and increases circulating GH, ACTH, cortisol, prolactin, and glucose across varied patient populations. There is a paucity of evidence regarding the effects of ghrelin on LH, FSH, TSH, insulin, lipolysis, body composition, cardiac function, pulmonary function, the vasculature, and sleep. Adverse effects occurred in 20% of participants, with a predominance of flushing and gastric rumbles and a mild degree of severity. The few serious adverse events occurred in patients with advanced illness and were not clearly attributable to ghrelin. Route of administration may affect the pattern of adverse effects. Conclusions: Existing literature supports the short-term safety of ghrelin administration and its efficacy as an appetite stimulant in diverse patient populations. There is some evidence to suggest that ghrelin has wider ranging therapeutic effects, although these areas require further investigation. PMID:23533240

Ayahuasca is the Quechua name for a tea obtained from the vine Banisteriopsis caapi, and used for ritual purposes by the indigenous populations of the Amazon. The use of a variation of the tea that combines B. caapi with the leaves of the shrub Psychotria viridis has experienced unprecedented expansion worldwide for its psychotropic properties. This preparation contains the psychedelic 5-HT 2A receptor agonist N,N-dimethyltryptamine (DMT) from P. viridis, plus β-carboline alkaloids with monoamine-oxidase-inhibiting properties from B. caapi. Acute administration induces a transient modified state of consciousness characterized by introspection, visions, enhanced emotions and recollection of personal memories. A growing body of evidence suggests that ayahuasca may be useful to treat substance use disorders, anxiety and depression. Here we review the pharmacology and neuroscience of ayahuasca, and the potential psychological mechanisms underlying its therapeutic potential. We discuss recent findings indicating that ayahuasca intake increases certain mindfulness facets related to acceptance and to the ability to take a detached view of one's own thoughts and emotions. Based on the available evidence, we conclude that ayahuasca shows promise as a therapeutic tool by enhancing self-acceptance and allowing safe exposure to emotional events. We postulate that ayahuasca could be of use in the treatment of impulse-related, personality and substance use disorders and also in the handling of trauma. More research is needed to assess the full potential of ayahuasca in the treatment of these disorders. Copyright © 2016 Elsevier Inc. All rights reserved.

The liver is the most common site of metastatic tumour deposits. Hepatic metastases are the major cause of morbidity and mortality in patients with gastrointestinal carcinomas and other malignant tumours. The rationale and results for interventional therapeutic techniques in the treatment of liver metastases are presented. For the treatment of patients with irresectable liver metastases, alternative local ablative therapeutic modalities have been developed. Technique and results of local interventional therapies are presented such as microwave-, radiofrequency (RF)- and ultrasound ablation, and laser-induced interstitial therapy (LITT), cryotherapy and local drug administration such as alcohol injection, endotumoral chemotherapy and regional chemoembolisation. In addition to cryotherapy, all ablative techniques can be performed percutaneously with low morbidity and mortality. Cryotherapy is an effective and precise technique for inducing tumour necrosis, but it is currently performed via laparotomy. Percutaneous local alcohol injection results in an inhomogeneous distribution in liver metastases with unreliable control rates. Local chemotherapeutic drug instillation and regional chemoembolisation produces relevant but non-reproducible lesions. Laser-induced interstitial thermotherapy (LITT) performed under MRI guidance results in precise and reproducible areas of induced necrosis with a local control of 94 %, and with an improved survival rate. Interventional therapeutic techniques of liver metastases do result in a remarkable local tumour control rate with improved survival results. (orig.) With 5 figs., 1 tab., 43 refs.

Over the last few years, the use of self-ligating brackets in orthodontics has progressed considerably. These systems have been the subject of numerous studies with good levels of evidence making it possible to evaluate their efficacy and efficiency compared to conventional brackets. The aim of this study was to evaluate the therapeutic efficacy of self-ligating brackets by means of a systematic review of the scientific literature. A systematic study was undertaken in the form of a recent search of the electronic Pubmed database, oriented by the use of several keywords combined by Boolean operators relating to the therapeutic efficacy of self-ligating brackets through the study of tooth alignment, space closure, expansion, treatment duration and degree of discomfort. The search was limited to randomized controlled studies, and two independent readers identified studies corresponding to the selection criteria. The chosen articles comprised 20 randomized controlled trials. The studies analyzed revealed the absence of significant differences between the two types of system on the basis of the clinical criteria adopted, thereby refuting the hypothesis of the superiority of self-ligating brackets over conventional systems.

In real situations, the value of public goods will be reduced or even lost because of external factors or for intrinsic reasons. In this work, we investigate the evolution of cooperation by considering the effect of depreciation of public goods in spatial public goods games on a square lattice. It is assumed that each individual gains full advantage if the number of the cooperators nc within a group centered on that individual equals or exceeds the critical mass (CM). Otherwise, there is depreciation of the public goods, which is realized by rescaling the multiplication factor r to (nc/CM)r. It is shown that the emergence of cooperation is remarkably promoted for CM > 1 even at small values of r, and a global cooperative level is achieved at an intermediate value of CM = 4 at a small r. We further study the effect of depreciation of public goods on different topologies of a regular lattice, and find that the system always reaches global cooperation at a moderate value of CM = G - 1 regardless of whether or not there exist overlapping triangle structures on the regular lattice, where G is the group size of the associated regular lattice.

Based on a 1994 national survey of Community and Migrant Health Center (C/MHC) administrators, this study draws a profile of C/MHC administrators in terms of their personal and work characteristics, as well as their values and beliefs regarding successful C/MHC attributes and important managerial practices. Further, the study compares C/MHC administrators with different educational preparation in terms of their personal and work characteristics, values and beliefs, as well as their perceived deficiencies. The study results indicate that critical factors in C/MHC success, in order of ranked importance, were good organizational leadership, organization's value to community and efficiency. Successful managerial characteristics, in order of ranked importance, were vision for the future of organization, honesty/integrity and open to new possibilities. Administrators with more advanced degrees expressed less deficiencies and those with no college degree showed greatest deficiency on five of eight measures.

Abnormal (keloid and hypertrophic) scars are a significant affliction with no satisfactory single modality therapy to-date. Available options are often ineffective, painful, potentially hazardous, and require healthcare personnel involvement. Herein a self-administered microneedle device based on drug-free physical contact for inhibiting abnormal scars is reported. Its therapeutic activity through microneedle contact eliminates hazards associated with toxic anti-scarring drugs while self-treatment enables administration flexibility. The microneedle patch was fabricated with FDA-approved liquid crystalline polymer under good manufacturing practice. It was first tested to ascertain its ability to inhibit (keloid) fibroblast proliferation. Later the microneedle patch was examined on the rabbit ear hypertrophic scar model to explore its potential in inhibiting the generation of abnormal scars post-injury. Finally, the microneedle patch was applied to the caudal region of a hypertrophic scar located on a female patient's dorsum to verify clinical efficacy. On untreated control cultures, barely any non-viable fibroblasts could be seen. After 12-h treatment with the microneedle patch, the non-viable proportion increased to 83.8 ± 11.96%. In rabbit ear hypertrophic scar model, 100% of the control wounds without the presence of patches on rabbit ears generated regions of raised dermis originating from the wound site (3/3), whereas microneedle treatment prevented dermis tissue thickening in 83.33% of the wounds (15/18). In the clinical test, the microneedle patch was well tolerated by the patient. Compared to the untreated region, microneedle treatment decreased the number of infiltrated inflammatory cells, with less disrupted dermis tissue architecture and more flattened appearance. A self-administered, drug-free microneedle patch appears highly promising in reducing abnormal scarring as observed from in vitro, in vivo and clinical experiments. Larger cohort clinical

Tissue banking in australia.

2003-01-01

The legal structure for the regulation of tissue banking has existed for many years. In Australia, the donation of human tissue is regulated by legislation in each of the eight States and Territories. These substantially uniform Acts were passed in the late 1970's and early 1980's, based on model legislation and underpinned by the concept of consensual giving. However, it was not until the early 1990's that tissue banking came under the notice of regulatory authorities. Since then the Australian Government has moved quickly to oversee the tissue banking sector in Australia. Banked human tissue has been deemed to be a therapeutic good under the Therapeutic Goods Act 1989, and tissue banks are required to be licensed by the Therapeutic Goods Administration and are audited for compliance with the Code of Good Manufacturing Practice- Human Blood and Tissues. In addition, tissue banks must comply with a myriad of other standards, guidelines and recommendations.

To design and select the next generation of ocular therapeutics, we performed a comprehensive ocular and systemic pharmacokinetic (PK) analysis of a variety of antibodies and antibody fragments, including a novel-designed bispecific antibody. Molecules were administrated via intravitreal (IVT) or intravenous (IV) injections in rabbits, and antibody concentrations in each tissue were determined by ELISA. A novel mathematical model was developed to quantitate the structure-PK relationship. After IVT injection, differences in vitreal half-life observed across all molecules ranged between 3.2 and 5.2 days. Modification or elimination of the fragment crystallizable (Fc) region reduced serum half-life from 9 days for the IgG to 5 days for the neonatal Fc receptor (FcRn) null mAb, to 3.1 to 3.4 days for the other formats. The F(ab')2 was the optimal format for ocular therapeutics with comparable vitreal half-life to full-length antibodies, but with minimized systemic exposure. Concomitantly, the consistency among mathematical model predictions and observed data validated the model for future PK predictions. In addition, we showed a novel design to develop bispecific antibodies, here with activity targeting multiple angiogenesis pathways. We demonstrated that protein molecular weight and Fc region do not play a critical role in ocular PK, as they do systemically. Moreover, the mathematical model supports the selection of the "ideal therapeutic" by predicting ocular and systemic PK of any antibody format for any dose regimen. These findings have important implications for the design and selection of ocular therapeutics according to treatment needs, such as maximizing ocular half-life and minimizing systemic exposure.

Pulmonary edema and the associated increases in vascular permeability continue to represent a significant clinical problem in the intensive care setting, with no current treatment modality other than supportive care and mechanical ventilation. Therapeutic compound(s) capable of attenuating changes in vascular barrier function would represent a significant advance in critical care medicine. We have previously reported the development of HPMA-based copolymers, targeted to endothelial glycocalyx that are able to enhance barrier function. In this work, we report the refinement of copolymer design and extend our physiological studies todemonstrate that the polymers: 1) reduce both shear stress and pressure-mediated increase in hydraulic conductivity, 2) reduce nitric oxide production in response to elevated hydrostatic pressure and, 3) reduce the capillary filtration coefficient (Kfc) in an isolated perfused mouse lung model. These copolymers represent an important tool for use in mechanotransduction research and a novel strategy for developing clinically useful copolymers for the treatment of vascular permeability.

2011-06-15

The development of novel substance use disorder (SUD) therapeutics is insufficient to meet the medical needs of a growing SUD patient population. The identification of translatable SUD models and tests is a crucial step in establishing a framework for SUD therapeutic development programs. The present review begins by identifying the clinical features of SUDs and highlights the narrow regulatory end-point required for approval of a novel SUD therapeutic. A conceptual overview of dependence is provided, followed by identification of potential intervention targets in the addiction cycle. The main components of the addiction cycle provide the framework for a discussion of preclinical models and their clinical analogs, all of which are focused on isolated behavioral end-points thought to be relevant to the persistence of compulsive drug use. Thus, the greatest obstacle to successful development is the gap between the multiplicity of preclinical and early clinical end-points and the regulatory end-point of sustained abstinence. This review proposes two pathways to bridging this gap: further development and validation of the preclinical extended access self-administration model; inclusion of secondary end-points comprising all of the measures highlighted in the present discussion in Phase 3 trials. Further, completion of the postdictive validation of analogous preclinical and clinical assays is of high priority. Ultimately, demonstration of the relevance and validity of a variety of end-points to the ultimate goal of abstinence will allow researchers to identify truly relevant therapeutic mechanisms and intervention targets, and establish a framework for SUD therapeutic development that allows optimal decision-making and resource allocation. 2011 Elsevier Inc.

Full Text Available Botulinum toxins (BoNTs are produced by several anaerobic species of the genus Clostridium and, although they were originally considered lethal toxins, today they find their usefulness in the treatment of a wide range of pathologies in various medical specialties. Botulinum neurotoxin has been identified in seven different isoforms (BoNT-A, BoNT-B, BoNT-C, BoNT-D, BoNT-E, BoNT-F, and BoNT-G. Neurotoxigenic Clostridia can produce more than 40 different BoNT subtypes and, recently, a new BoNT serotype (BoNT-X has been reported in some studies. BoNT-X has not been shown to actually be an active neurotoxin despite its catalytically active LC, so it should be described as a putative eighth serotype. The mechanism of action of the serotypes is similar: they inhibit the release of acetylcholine from the nerve endings but their therapeutically potency varies. Botulinum toxin type A (BoNT-A is the most studied serotype for therapeutic purposes. Regarding the gynecological pathology, a series of studies based on the efficiency of its use in the treatment of refractory myofascial pelvic pain, vaginism, dyspareunia, vulvodynia and overactive bladder or urinary incontinence have been reported. The current study is a review of the literature regarding the efficiency of BoNT-A in the gynecological pathology and on the long and short-term effects of its administration.

In this regard, tumor size is one of the two main prognostic factors for surgical resection, which constitutes the only curative treatment for HCC along with liver transplantation. However, techniques for HCC surveillance and diagnosis that are currently used in clinical practice have certain limitations that may be inherent to the tumor development. Thus, it is important to continue efforts in the search for biomarkers that increase diagnostic accuracy for HCC. In this review, we focus on different biological sources of candidate biomarkers for HCC diagnosis. Although those biomarkers identified from biological samples obtained by noninvasive methods have greater diagnostic value, we have also considered those obtained from liver tissue because of their potential therapeutic value. To date, sorafenib is the only US Food and Drug Administration-approved antineoplastic for HCC. However, this therapeutic agent shows very low tumor response rates and frequently causes acquired resistance in HCC patients. We discuss the use of HCC biomarkers as therapeutic targets themselves, or as targets to increase sensitivity to sorafenib treatment. Keywords: diagnosis, sorafenib, therapy

MIS416 Enhances Therapeutic Functions of Human Umbilical Cord Blood-Derived Mesenchymal Stem Cells Against Experimental Colitis by Modulating Systemic Immune Milieu

2018-05-01

Full Text Available Human adult stem cells, including umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs, have recently been considered a promising alternative treatment for inflammatory bowel disease (IBD due to their unique immunomodulatory properties and ability to promote tissue regeneration. However, despite many years of research and pre-clinical studies, results from clinical trials using these cells have been diverse and conflicting. This discrepancy is caused by several factors, such as poor engraftment, low survival rate, and donor-dependent variation of the cells. Enhancement of consistency and efficacy of MSCs remains a challenge for the feasibility of cell-based therapy. In this study, we investigated whether administration of MIS416, a novel microparticle that activates NOD2 and TLR9 signaling, could enhance the therapeutic efficacy of hUCB-MSCs against Crohn’s disease, using dextran sulfate sodium (DSS-induced colitis model. Colitis was experimentally induced in mice by using 3% DSS, and mice were administered a retro-orbital injection of MIS416 and subsequent intraperitoneal injection of hUCB-MSCs. Mice were examined grossly, and blood, spleen, and colon tissues were subsequently collected for further ex vivo analyses. To explore the effects of MIS416 on the therapeutic process, hUCB-MSCs and primary isolated immune cells were cultured with MIS416, and in vitro assays were performed. Compared to the single administration of hUCB-MSCs, co-administration with MIS416 improved the therapeutic efficiency of the stem cells by significantly alleviating the symptoms of IBD. Interestingly, MIS416 did not exert any direct effect on the immunomodulatory capacity of hUCB-MSCs. Instead, systemically injected MIS416 altered the immune milieu in the colon which caused hUCB-MSCs to be more readily recruited toward the lesion site and to suppress inflammation more efficiently. In addition, considerable numbers of regulatory immune cells were stimulated

In real situations, the value of public goods will be reduced or even lost because of external factors or for intrinsic reasons. In this work, we investigate the evolution of cooperation by considering the effect of depreciation of public goods in spatial public goods games on a square lattice. It is assumed that each individual gains full advantage if the number of the cooperators n c within a group centered on that individual equals or exceeds the critical mass (CM). Otherwise, there is depreciation of the public goods, which is realized by rescaling the multiplication factor r to (n c /CM)r. It is shown that the emergence of cooperation is remarkably promoted for CM > 1 even at small values of r, and a global cooperative level is achieved at an intermediate value of CM = 4 at a small r. We further study the effect of depreciation of public goods on different topologies of a regular lattice, and find that the system always reaches global cooperation at a moderate value of CM = G − 1 regardless of whether or not there exist overlapping triangle structures on the regular lattice, where G is the group size of the associated regular lattice

Full Text Available Objectives Banha-sasim-tang (BST, which consists of seven different herbs, is one of the most popular herbal formulae for treating gastrointestinal disorders in Eastern Asia. The commonly used herbal medicine is often co-administered with other therapeutic drugs, which raises the possibility of herb–drug interactions and may modify the clinical safety profile of therapeutic drugs. Methods We investigated the potential herb–drug interactions between BST extract and midazolam (MDZ in mice. The area under the plasma concentration-time curve (AUC of MDZ and 1ʹ-hydroxymidazolam (1ʹ-OH-MDZ was evaluated for both oral and intraperitoneal administration of MDZ, following oral administration of BST (0.5 and 1 g/kg. Results It was found that the AUC of MDZ and 1ʹ-OH-MDZ was lower in case of oral administration of MDZ. Administration of BST extract was not associated with hepatic cytochrome P450 activity. BST extract induced a strong reduction in pH and it has been reported that oral mucosal absorption of MDZ is lower at low pH. The decreased absorption rate of MDZ might be caused by the ingredients of BST and may not be related to other factors such as increased excretion of MDZ by P-glycoprotein. Conclusions The altered pharmacokinetics of midazolam caused by co-administration with BST in vivo could be attributed to a decrease in pH and subsequent reduction of MDZ absorption rate.

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

Full Text Available Introduction: The glutamatergic system plays an important role in learning and memory. Administration of crocus sativus (Saffron or its constituent, crocin, facilitates the formation of memory. This research investigated the effect of crocin on antagonizing retrograde amnesia induced by ketamine, a glutamatergic receptor antagonist, in rats by shuttle box. Methods: Male Wistar rats were tested to measure their learning behavior in the passive avoidance task. All animals were trained by a 1 mA shock. The drugs were injected immediately after the training was successfully performed. The animals were tested 24h after training to measure Step Through Latency (STL. Results: On the test day, administration of ketamine (12 mg/kg, ip impaired the memory after training. Different doses of crocin (2, 5 or 10 mg/kg, ip were injected 30 min after ketamine, but only 2 mg/kg crocin could improve retrograde amnesia and 5 and 10 mg/kg doses did not have any significant effect on retrograde amnesia. Moreover, administration of crocin (2, 5 or 10 mg/kg, ip after training had no significant impact on passive avoidance memory by itself. Conclusion: Considering the therapeutic effect of post-training administration of crocin on ketamine-induced retrograde amnesia, it can be argued that crocin has an interaction with glutamatergic system in formation of passive avoidance memory in rats.

Nuclear transfer and therapeutic cloning have widespread and attractive prospects in animal agriculture and biomedical applications. We reviewed that the quality of oocytes and nuclear reprogramming of somatic donor cells were the main reasons of the common abnormalities in cloned animals and the low efficiency of cloning and showed the problems and outlets in therapeutic cloning, such as some basic problems in nuclear transfer affected clinical applications of therapeutic cloning. Study on isolation and culture of nuclear transfer embryonic stem (ntES) cells and specific differentiation of ntES cells into important functional cells should be emphasized and could enhance the efficiency. Adult stem cells could help to cure some great diseases, but could not replace therapeutic cloning. Ethics also impeded the development of therapeutic cloning. It is necessary to improve many techniques and reinforce the research of some basic theories, then somatic nuclear transfer and therapeutic cloning may apply to agriculture reproduction and benefit to human life better.

Hibiscus sabdariffa L. (roselle) belonging to the Malvaceae family is widely grown in many countries. This plant is often used in the traditional medicine being rich in phytochemicals like polyphenols especially anthocyanins, polysaccharides and organic acids thus having enormous prospective in modern therapeutic uses. The study aimed to review and document all the available evidence and information about the calyces of Hibiscus sabdariffa (roselle) with the special focus on their nutritional composition, bioactive constituents and therapeutic uses. The electronic database was searched up to 2017, using keywords Hibiscus sabdariffa, chemical constituents of roselle, therapeutic uses of roselle. Journals, books and conference proceedings were also searched. The review provides valuable information about the nutraceutical component of Hibiscus sabdariffa L. and their utilization for curing various degenerative diseases like hypertension, hyperlipidemia, cancer and other inflammatory diseases of liver and kidney. Their toxicological effects have also been discussed from a safety point of view. Most studies supported and provided the scientific basis for the statement that Hibiscus sabdariffa and their active constituents play an important role in the prevention of chronic and degenerative diseases that are associated with oxidative stress. Our study suggests, that good research is needed, to establish a potential strategy that can balance the pharmacological and toxic effects of roselle and standardized fingerprint of Hibiscus sabdariffa is required internationally for quality control.

2011-09-01

Full Text Available Leishmaniasis remains a significant cause of morbidity and mortality in the tropics. Available therapies are problematic due to toxicity, treatment duration and emerging drug resistance. Mouse models of leishmaniasis have demonstrated that disease outcome depends critically on the balance between effector and regulatory CD4(+ T cell responses, something mirrored in descriptive studies of human disease. Recombinant IL-2/diphtheria toxin fusion protein (rIL-2/DTx, a drug that is FDA-approved for the treatment of cutaneous T cell lymphoma, has been reported to deplete regulatory CD4(+ T cells.We investigated the potential efficacy of rIL-2/DTx as adjunctive therapy for experimental infection with Leishmania major. Treatment with rIL-2/DTx suppressed lesional regulatory T cell numbers and was associated with significantly increased antigen-specific IFN-γ production, enhanced lesion resolution and decreased parasite burden. Combined administration of rIL-2/DTx and sodium stibogluconate had additive biological and therapeutic effects, allowing for reduced duration or dose of sodium stibogluconate therapy.These data suggest that pharmacological suppression of immune counterregulation using a commercially available drug originally developed for cancer therapy may have practical therapeutic utility in leishmaniasis. Rational reinvestigation of the efficacy of drugs approved for other indications in experimental models of neglected tropical diseases has promise in providing new candidates to the drug discovery pipeline.

The efficiency of taurine therapy for treatment of male mice exposed to a dose of (3 Gy) whole body gamma irradiation and their male offspring was studied after administration taurine 1% in drinking water post irradiation. Administration of taurine therapy resulted in a significant decrease in the effect of irradiation on chromosomal aberrations in irradiated animals and their male offspring. The efficiency of taurine as radio therapeutic agent is greatly dependent on its chemical properties as strong oxidants scavenger and biological activities as osmoregulator and membrane stabilizer. The probable mechanism of taurine therapy was discussed

2018-01-29

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

Linezolid is an effective antibiotic against most gram-positive bacteria including drug-resistant strains such as methicillin-resistant Staphylococcus aureus. Although linezolid therapy is known to result in thrombocytopenia, dosage adjustment or therapeutic drug monitoring of linezolid is not generally necessary. In this report, however, we describe the case of a 79-year-old woman with recurrent methicillin-resistant S. aureus osteomyelitis that was successfully treated via surgery and combination therapy using linezolid and rifampicin under therapeutic drug monitoring for maintaining an appropriate serum linezolid concentration. The patient underwent surgery for the removal of the artificial left knee joint and placement of vancomycin-impregnated bone cement beads against methicillin-resistant S. aureus after total left knee implant arthroplasty for osteoarthritis. We also initiated linezolid administration at a conventional dose of 600 mg/h at 12-h intervals, but reduced it to 300 mg/h at 12-h intervals on day 9 because of a decrease in platelet count and an increase in serum linezolid trough concentration. However, when the infection exacerbated, we again increased the linezolid dose to 600 mg/h at 12-h intervals and performed combination therapy with rifampicin, considering their synergistic effects and the control of serum linezolid trough concentration via drug interaction. Methicillin-resistant S. aureus infection improved without reducing the dose of or discontinuing linezolid. The findings in the present case suggest that therapeutic drug monitoring could be useful for ensuring the therapeutic efficacy and safety of combination therapy even in patients with osteomyelitis who require long-term antibiotic administration.

Porter, Maree; Kerridge, Ian H; Jordens, Christopher F C

2012-03-01

Umbilical cord blood banking is one of many biomedical innovations that confront pregnant women with new choices about what they should do to secure their own and their child's best interests. Many mothers can now choose to donate their baby's umbilical cord blood (UCB) to a public cord blood bank or pay to store it in a private cord blood bank. Donation to a public bank is widely regarded as an altruistic act of civic responsibility. Paying to store UCB may be regarded as a "unique opportunity" to provide "insurance" for the child's future. This paper reports findings from a survey of Australian women that investigated the decision to either donate or store UCB. We conclude that mothers are faced with competing discourses that force them to choose between being a "good mother" and fulfilling their role as a "good citizen." We discuss this finding with reference to the concept of value pluralism.

Anti-Parkinson Potential of Silymarin: Mechanistic Insight and Therapeutic Standing

Full Text Available Parkinson’s disease (PD involves aggregation of α-synuclein and progressive loss of dopaminergic neurons. Pathogenesis of PD may also be related to one’s genetic background. PD is most common among geriatric population and approximately 1–2% of population suffers over age 65 years. Currently no successful therapies are in practice for the management of PD and available therapies tend to decrease the symptoms of PD only. Furthermore, these are associated with diverse range of adverse effects profile. The neuroprotective effects of polyphenols are widely studied and documented. Among phytochemicals, silymarin is one of the most widely used flavonoids because of its extensive therapeutic properties and has been indicated in pathological conditions of prostate, CNS, lungs, skin, liver, and pancreas. Silymarin is a mixture of flavonolignans (silybin, isosilybin, and silychristin, small amount of flavonoids (taxifolin, fatty acids, and other polyphenolic compounds extracted from the dried fruit of Silybum marianum and is clinically used for hepatoprotective effects since ancient times. Neuroprotective effects of silymarin have been studied in various models of neurological disorders such as Alzheimer’s disease, PD, and cerebral ischemia. The aim of the present study is to provide a comprehensive review of the recent literature exploring the effects of silymarin administration on the progression of PD. Reducing oxidative stress, inflammatory cytokines, altering cellular apoptosis machinery, and estrogen receptor machinery are mechanisms that are responsible for neuroprotection by silymarin, as discussed in this review. Additionally, because of poor aqueous solubility, the bioavailability of silymarin is low and only 23–47% of silymarin reaches systemic circulation after oral administration. Our primary focus is on the chemical basis of the pharmacology of silymarin in the treatment of PD and its mechanisms and possible therapeutic

2018-01-01

Full Text Available Both chronic and acute (binge alcohol drinking are important health and economic concerns worldwide and prominent risk factors for the development of alcoholic liver disease (ALD. There are no FDA-approved medications to prevent or to treat any stage of ALD. Therefore, discovery of novel therapeutic strategies remains a critical need for patients with ALD. Relevant experimental animal models that simulate human drinking patterns and mimic the spectrum and severity of alcohol-induced liver pathology in humans are critical to our ability to identify new mechanisms and therapeutic targets. There are several animal models currently in use, including the most widely utilized chronic ad libitum ethanol (EtOH feeding (Lieber–DeCarli liquid diet model, chronic intragastric EtOH administration (Tsukamoto–French model, and chronic-plus-binge EtOH challenge (Bin Gao—National Institute on Alcohol Abuse and Alcoholism (NIAAA model. This review provides an overview of recent advances in rodent models of binge EtOH administration which help to recapitulate different features and etiologies of progressive ALD. These models include EtOH binge alone, and EtOH binge coupled with chronic EtOH intake, a high fat diet, or endotoxin challenge. We analyze the strengths, limitations, and translational relevance of these models, as well as summarize the liver injury outcomes and mechanistic insights. We further discuss the application(s of binge EtOH models in examining alcohol-induced multi-organ pathology, sex- and age-related differences, as well as circadian rhythm disruption.

We have recently proposed that retinoic acid receptor (NR1B) is a promising target of neuroprotective therapy for intracerebral hemorrhage, since pretreatment of mice with an NR1B1/NR1B2 agonist Am80 attenuated various pathological and neurological abnormalities associated with the disease. In the present study we further addressed the effects of retinoids as potential therapeutic drugs, using a collagenase-induced model of intracerebral hemorrhage. Daily oral administration of all-trans retinoic acid (ATRA; 5 and 15 mg/kg), a naturally occurring NR1B agonist, from 1 day before collagenase injection significantly inhibited loss of neurons within the hematoma. ATRA in the same treatment regimen also decreased the number of activated microglia/macrophages around the hematoma but did not affect the hematoma volume. ATRA (15 mg/kg) as well as Am80 (5mg/kg) rescued neurons in the central region of hematoma, even when drug administration was started from 6h after induction of intracerebral hemorrhage. However, in this post-treatment regimen, only Am80 significantly decreased the number of activated microglia/macrophages. With regard to neurological deficits, both ATRA (15 mg/kg) and Am80 (5mg/kg) given in the post-treatment regimen improved performance of mice in the beam-walking test and the modified limb-placing test. ATRA and Am80 also significantly attenuated damage of axon tracts as revealed by amyloid precursor protein immunohistochemistry. These results underscore potential therapeutic values of NR1B agonists for intracerebral hemorrhage. Copyright © 2012 Elsevier B.V. All rights reserved.

Ayahuasca is a psychotropic plant tea used for ritual purposes by the indigenous populations of the Amazon. In the last two decades, its use has expanded worldwide. The tea contains the psychedelic 5-HT2A receptor agonist N,N-dimethyltryptamine (DMT), plus β-carboline alkaloids with monoamine-oxidase-inhibiting properties. Acute administration induces an introspective dream-like experience characterized by visions and autobiographic and emotional memories. Studies of long-term users have suggested its therapeutic potential, reporting that its use has helped individuals abandon the consumption of addictive drugs. Furthermore, recent open-label studies in patients with treatment-resistant depression found that a single ayahuasca dose induced a rapid antidepressant effect that was maintained weeks after administration. Here, we conducted an exploratory study of the psychological mechanisms that could underlie the beneficial effects of ayahuasca. We assessed a group of 25 individuals before and 24 h after an ayahuasca session using two instruments designed to measure mindfulness capacities: The Five Facets Mindfulness Questionnaire (FFMQ) and the Experiences Questionnaire (EQ). Ayahuasca intake led to significant increases in two facets of the FFMQ indicating a reduction in judgmental processing of experiences and in inner reactivity. It also led to a significant increase in decentering ability as measured by the EQ. These changes are classic goals of conventional mindfulness training, and the scores obtained are in the range of those observed after extensive mindfulness practice. The present findings support the claim that ayahuasca has therapeutic potential and suggest that this potential is due to an increase in mindfulness capacities.

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

Irradiation of goods

Lunt, R.E.

1987-01-01

Mechanical handling apparatus is adapted to handle goods, such as boxed fruit, during a process of irradiation, in palletized form. Palletized goods are loaded onto wheeled vehicles in a loading zone. Four vehicles are wheeled on a track into an irradiation zone via a door in a concrete shield. The vehicles are arranged in orthogonal relationship around a source of square section. Turntables are positioned at corners of the square shaped rail truck around the source selectively to turn the vehicles to align then with track sections. Mechanical manipulating devices are positioned in the track sections opposed to sides of the source. During irradiation, the vehicles and their palletized goods are cylically moved toward the source to offer first sides of the goods for irradiation and are retraced from the source and are pivoted through 90 0 to persent succeeding sides of the goods for irradiation

Hydrogen exerts beneficial effects in disease animal models of ischemia-reperfusion injury as well as inflammatory and neurological disease. Additionally, molecular hydrogen is useful for various novel medical and therapeutic applications in the clinical setting. In the present study, the hydrogen concentration in rat blood and tissue was estimated. Wistar rats were orally administered hydrogen super-rich water (HSRW), intraperitoneal and intravenous administration of hydrogen super-rich saline (HSRS), and inhalation of hydrogen gas. A new method for determining the hydrogen concentration was then applied using high-quality sensor gas chromatography, after which the specimen was prepared via tissue homogenization in airtight tubes. This method allowed for the sensitive and stable determination of the hydrogen concentration. The hydrogen concentration reached a peak at 5 minutes after oral and intraperitoneal administration, compared to 1 minute after intravenous administration. Following inhalation of hydrogen gas, the hydrogen concentration was found to be significantly increased at 30 minutes and maintained the same level thereafter. These results demonstrate that accurately determining the hydrogen concentration in rat blood and organ tissue is very useful and important for the application of various novel medical and therapeutic therapies using molecular hydrogen.

Hydrogen exerts beneficial effects in disease animal models of ischemia-reperfusion injury as well as inflammatory and neurological disease. Additionally, molecular hydrogen is useful for various novel medical and therapeutic applications in the clinical setting. In the present study, the hydrogen concentration in rat blood and tissue was estimated. Wistar rats were orally administered hydrogen super-rich water (HSRW), intraperitoneal and intravenous administration of hydrogen super-rich saline (HSRS), and inhalation of hydrogen gas. A new method for determining the hydrogen concentration was then applied using high-quality sensor gas chromatography, after which the specimen was prepared via tissue homogenization in airtight tubes.

ALTERNATIVE ROUTES OF DRUG ADMINISTRATION: ADVANTAGES AND DISADVANTAGES (SUBJECT REVIEW OF AMERICAN ACADEMY OF PEDIATRICS

Directory of Open Access Journals (Sweden)

article editorial

2006-01-01

Full Text Available During the past 20 years advances in drug formulations and innovative routes of administration have been made. Our understanding of drug transport across tissues has increased. These changes have often resulted in improved patient adherence to the therapeutic regiment and pharmacologic response. The administration of drugs by transdermal or transmucosal routes offers the advantage of being relatively painless. Also, the potential for greater flexibility in a variety of clinical situations exists, often precluding the need to establish intravinus access which is a particular benefit for children. This statement focuses on the advantages and disadvantages of alternative routes of drug administration. Issues of particular importance in the care of pediatric patients especially factors that could lead to drug-relaxed toxicity or adverse responses are emphasized.Key words: drug formulation, pharmacoKINETICS, pharmacodynamics, drug, children.

nature of the lesion, with those containing hepatocytes being enhanced. Most patients exhibited a sensation of hot flashes (28 of 31, 90%) and no discomfort in the area of injection. No other adverse reactions were reported. Bolus administration of Teslascan (∼ 1 ml/s) is safe, effective, and helpful in the detection and characterization of focal lesions. A combination of GE T1 and STIR sequences after contrast administration maximizes the detection of hepatic lesions. Manganese is useful in confirming the hepatocellular origin of both lesions and findings associated with cirrhosis of the liver, which is helpful in classifying the lesions. Lack of contrast enhancement in previously treated CHC patients should be considered evidence of its therapeutic success. (Author) 17 refs

Sustained Administration of Hormones Exploiting Nanoconfined Diffusion through Nanochannel Membranes

Thomas Geninatti

2015-08-01

Full Text Available Implantable devices may provide a superior means for hormone delivery through maintaining serum levels within target therapeutic windows. Zero-order administration has been shown to reach an equilibrium with metabolic clearance, resulting in a constant serum concentration and bioavailability of released hormones. By exploiting surface-to-molecule interaction within nanochannel membranes, it is possible to achieve a long-term, constant diffusive release of agents from implantable reservoirs. In this study, we sought to demonstrate the controlled release of model hormones from a novel nanochannel system. We investigated the delivery of hormones through our nanochannel membrane over a period of 40 days. Levothyroxine, osteocalcin and testosterone were selected as representative hormones based on their different molecular properties and structures. The release mechanisms and transport behaviors of these hormones within 3, 5 and 40 nm channels were characterized. Results further supported the suitability of the nanochannels for sustained administration from implantable platforms.

Full Text Available Massive Hemoptysis and pulmonary embolism are two very severe and potentially fatal pulmonary emergencies requiring completely different treatments. We present the case of a 45-year old male transmitted to our Hospital for massive hemoptysis who at the same time was found to suffer from pulmonary embolism. Hemoptysis was treated with bronchial artery embolization which resulted in cessation of haemorrhage and allowed the administration of anticoagulant therapy a few days later. This case report gives an answer on how to manage a real therapeutic conundrum which is the coexistence of a massive hemoptysis and a concomitant pulmonary embolism.

Human Factor in Therapeutic Relationship

Directory of Open Access Journals (Sweden)

Ramazan Akdogan

2011-03-01

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

Cymer, Florian; Beck, Hermann; Rohde, Adelheid; Reusch, Dietmar

2018-03-01

Therapeutic antibodies (IgG-type) contain several post-translational modifications (PTMs) whereby introducing a large heterogeneity, both structural and functional, into this class of therapeutics. Of these modifications, glycosylation in the fragment crystallizable (Fc) region is the most heterogeneous PTM, which can affect the stability of the molecule and interactions with Fc-receptors in vivo. Hence, the glycoform distribution can affect the mode of action and have implications for bioactivity, safety and efficacy of the drug. Main topics of the manuscript include: What factors influence the (Fc) glycan pattern in therapeutic antibodies and how can these glycans be characterized? How does structure of the Fc-glycan relate to function and what methods are available to characterize those functions? Although heterogeneous in their scope, the different sections are intended to combine current knowledge on structure-function correlations of IgG glycan structures with regard to Fc (effector) functions, as well as basic aspects and methodologies for their assessment.

Administrative Transparency and the Access to Information

Directory of Open Access Journals (Sweden)

Luís Paulo Petersen Andreazza

2015-12-01

Full Text Available This article discusses the various forms and application ranges of the State secret throughout history, from its origins in classical political culture, to the evanescence of its intensity, when the right to information and the principles of good administration, advertising, transparency and democracy gain strength. In this scenario, in Brazil, the constitutional principle of transparency is highlighted, which transforms the notion of advertising, being no longer just an administrator option, to demand a public space in which the free movement of ideas and information starts to have potential to influence the scope and the action strategies of the State, providing certainty to State conducts and security to the administered. In the wake of this principle, comes the Access to Information Act, in order to print effectiveness in access to  administrative  information,  producing  intense  practical  effects  to  the  legal  and administrative relationship established between the Public Administration and administered and subjecting the power to control people, presenting a notorious identity with democracy. However, some points of this law provoked discussions regarding the possible conflict between individual and collective fundamental rights, as well as between the constitutional principles of transparency and publicity with the intimacy and privacy, as well as any collision with the infra-constitutional norms derived from the latter, as the confidentiality of financial data, bank secrecy and tax secrecy. The intention presented in this study is to establish the ownership of the reach of the Access to Information Act before the particular issue of disclosure in nominal compensation of state agents.

The influence of antithyroid drugs (ATDs) on the therapeutic efficacy of radioactive iodine in hyperthyroidism is still controversial. The aim of this study was to evaluate the effect of ATD discontinuation to the therapeutic efficacy of I-131 in hyperthyroidism patients with long-term ATD treatment. Retrospective study was done to 39 subjects with hyperthyroidism who had been treated with doses of 300 MBq radioactive iodine. The subjects were divided into three groups: Group I (n = 14) had been using ATDs for more than one year and discontinued more than three days; group II (n = 14) had been using ATDs for more than one year but discontinued only for three days or less, and group III (n = 11) has never been used any ATD before radioactive iodine treatment. There was a significant difference in the therapeutic efficacy after three months of radioactive iodine treatment between group I and group II (P = 0.018), group II and group III (P = 0.017), but not between group I and group III (P = 1.0). There was no observed difference on the therapeutic efficacy between the three groups at 6 months after radioactive iodine therapy (P = 0.143). Administration of ATDs more than 1 year without discontinuation decreased response of radioactive iodine treatment in 3 months follow-up. Discontinuation of ATDs for more than 3 days before radioactive iodine treatment is recommended

Therapeutic Use of Prebiotics, Probiotics, and Postbiotics to Prevent Necrotizing Enterocolitis: What is the Current Evidence?

Science.gov (United States)

Patel, Ravi Mangal; Denning, Patricia Wei

2013-01-01

Synopsis Necrotizing enterocolitis (NEC) is a leading cause of neonatal morbidity and mortality and preventative therapies that are both effective and safe are urgently needed. Current evidence from therapeutic trials suggests that probiotics are effective in decreasing NEC in preterm infants and probiotics are currently the most promising therapy on the horizon for this devastating disease. However, concerns regarding safety and optimal dosing have limited the widespread adoption of routine clinical use of probiotics in preterm infants. In addition, prebiotics and postbiotics may be potential alternatives or adjunctive therapies to the administration of live microorganisms, although studies demonstrating their clinical efficacy in preventing NEC are lacking. This review summarizes the current evidence regarding the use of probiotics, prebiotics and postbiotics in the preterm infant, including its therapeutic role in preventing NEC. PMID:23415261

The botulinum toxin as a therapeutic agent: molecular and pharmacological insights

Full Text Available Roshan Kukreja,1 Bal Ram Singh2 1Department of Chemistry and Biochemistry, University of Massachusetts, 2Botulinum Research Center, Institute of Advanced Sciences, Dartmouth, MA, USA Abstract: Botulinum neurotoxins (BoNTs, the most potent toxins known to mankind, are metalloproteases that act on nerve–muscle junctions to block exocytosis through a very specific and exclusive endopeptidase activity against soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE proteins of presynaptic vesicle fusion machinery. This very ability of the toxins to produce flaccid muscle paralysis through chemical denervation has been put to good use, and these potentially lethal toxins have been licensed to treat an ever expanding list of medical disorders and more popularly in the field of esthetic medicine. In most cases, therapeutic BoNT preparations are high-molecular-weight protein complexes consisting of BoNT, complexing proteins, and excipients. There is at least one isolated BoNT, which is free of complexing proteins in the market (Xeomin®. Each commercially available BoNT formulation is unique, differing mainly in molecular size and composition of complexing proteins, biological activity, and antigenicity. BoNT serotype A is marketed as Botox®, Dysport®, and Xeomin®, while BoNT type B is commercially available as Myobloc®. Nerve terminal intoxication by BoNTs is completely reversible, and the duration of therapeutic effects of BoNTs varies for different serotypes. Depending on the target tissue, BoNTs can block the cholinergic neuromuscular or cholinergic autonomic innervation of exocrine glands and smooth muscles. Therapeutic BoNTs exhibit a high safety and very limited adverse effects profile. Despite their established efficacy, the greatest concern with the use of therapeutic BoNTs is their propensity to elicit immunogenic reactions that might render the patient unresponsive to subsequent treatments, particularly in chronic

Translational nanomedicine--through the therapeutic window.

Pierce, Robin L

2015-01-01

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

Therapeutic enhancement: nursing intervention category for patients diagnosed with Readiness for Therapeutic Regimen Management.

Kelly, Cynthia W

2008-04-01

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

The therapeutic relationship after psychiatric admission.

LENUS (Irish Health Repository)

Roche, Eric

2014-03-01

The therapeutic relationship is one of the most central and important factors in the treatment of mental health disorders. A better therapeutic relationship is associated with service engagement, medication adherence, and satisfaction with services. This study aimed to compare the demographic and clinical factors associated with the therapeutic relationship in voluntarily and involuntarily admitted psychiatric service users. We found that individuals who had been admitted involuntarily, who had a diagnosis of a psychotic disorder, and who reported higher levels of perceived pressures on admission were more likely to have a poorer therapeutic relationship with their consultant psychiatrist. Greater levels of insight and treatment satisfaction, together with higher levels of procedural justice experienced on admission, were associated with a better therapeutic relationship. We found that the level of perceived coercion on admission was not related to the therapeutic relationship. Targeted interventions to improve the therapeutic relationship, particularly for involuntarily admitted service users, are discussed.

Grundmann Milan

2014-12-01

Full Text Available Schizophrenia is a severe psychiatric disorder often associated with cognitive impairment and affective, mainly depressive, symptoms. Antipsychotic medication is the primary intervention for stabilization of acute psychotic episodes and prevention of recurrences and relapses in patients with schizophrenia. Typical antipsychotics, the older class of antipsychotic agents, are currently used much less frequently than newer atypical antipsychotics. Therapeutic drug monitoring (TDM of antipsychotic drugs is the specific method of clinical pharmacology, which involves measurement of drug serum concentrations followed by interpretation and good cooperation with the clinician. TDM is a powerful tool that allows tailor-made treatment for the specific needs of individual patients. It can help in monitoring adherence, dose adjustment, minimizing the risk of toxicity and in cost-effectiveness in the treatment of psychiatric disorders. The review provides complex knowledge indispensable to clinical pharmacologists, pharmacists and clinicians for interpretation of TDM results.

Nanotechnological strategies for nerve growth factor delivery: Therapeutic implications in Alzheimer's disease.

Science.gov (United States)

Faustino, Célia; Rijo, Patrícia; Reis, Catarina Pinto

2017-06-01

Alzheimer's disease (AD) is a progressive neurodegenerative disorder associated with amyloid-β peptide misfolding and aggregation. Neurotrophic factors, such as nerve growth factor (NGF), can prevent neuronal damage and rescue the cholinergic neurons that undergo cell death in AD, reverse deposition of extracellular amyloid plaques and improve cognitive deficits. However, NGF administration is hampered by the poor pharmacokinetic profile of the therapeutic protein and its inability to cross the blood-brain barrier, which requires specialised drug delivery systems (DDS) for efficient NGF delivery to the brain. This review covers the main therapeutic approaches that have been developed for NGF delivery targeting the brain, from polymeric implants to gene and cell-based therapies, focusing on the role of nanoparticulate systems for the sustained release of NGF in the brain as a neuroprotective and disease-modifying approach toward AD. Lipid- and polymer-based delivery systems, magnetic nanoparticles and quantum dots are specifically addressed as promising nanotechnological strategies to overcome the current limitations of NGF-based therapies.

[Health security--GMOs in therapeutics].

Science.gov (United States)

Trouvin, J-H

2003-03-01

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

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

Therapeutic cloning in the mouse

2003-01-01

Nuclear transfer technology can be applied to produce autologous differentiated cells for therapeutic purposes, a concept termed therapeutic cloning. Countless articles have been published on the ethics and politics of human therapeutic cloning, reflecting the high expectations from this new opportunity for rejuvenation of the aging or diseased body. Yet the research literature on therapeutic cloning, strictly speaking, is comprised of only four articles, all in the mouse. The efficiency of derivation of embryonic stem cell lines via nuclear transfer is remarkably consistent among these reports. However, the efficiency is so low that, in its present form, the concept is unlikely to become widespread in clinical practice. PMID:12949262

Several opiate analgesics have low oral bioavailabilities in the dog because of presystemic metabolism. Intratracheal administration may circumvent this first-pass effect. Three anesthetized beagles received 5-mg/kg doses of codeine phosphate intratracheally (i.t.), orally (p.o.) and intravenously (i.v.) in a crossover study. The following drugs were also studied in similar experiments: ethylmorphine hydrochloride (5 mg/kg), pholcodine bitartrate (10 mg/kg, hydrocodone bitartrate (4 mg/kg) and morphine sulfate (2.5 mg/kg). Plasma drug concentrations over the 24- to 48-hr periods after drug administrations were determined by radioimmunoassays. I.t. bioavailabilities [codeine (84%), ethylmorphine (100%), and morphine (87%)] of drugs with poor oral availabilities were all markedly higher than the corresponding oral values (14, 26, and 23%, respectively). I.t. bioavailabilities of pholcodine (93%) and hydrocodone (92%), which have good oral availabilities (74 and 79%, respectively), were also enhanced. In all cases, peak plasma concentrations occurred more rapidly after i.t. (0.08-0.17 hr) than after oral (0.5-2 hr) dosing and i.t. disposition often resembled i.v. kinetics. I.t. administration may be a valuable alternative dosing route, providing rapid onset of pharmacological activity for potent drugs with poor oral bioavailability

The analytical characterization of therapeutic monoclonal antibodies and related proteins usually incorporates various sample preparation methodologies. Indeed, quantitative and qualitative information can be enhanced by simplifying the sample, thanks to the removal of sources of heterogeneity (e.g. N-glycans) and/or by decreasing the molecular size of the tested protein by enzymatic or chemical fragmentation. These approaches make the sample more suitable for chromatographic and mass spectrometric analysis. Structural elucidation and quality control (QC) analysis of biopharmaceutics are usually performed at intact, subunit and peptide levels. In this paper, general sample preparation approaches used to attain peptide, subunit and glycan level analysis are overviewed. Protocols are described to perform tryptic proteolysis, IdeS and papain digestion, reduction as well as deglycosylation by PNGase F and EndoS2 enzymes. Both historical and modern sample preparation methods were compared and evaluated using rituximab and trastuzumab, two reference therapeutic mAb products approved by Food and Drug Administration (FDA) and European Medicines Agency (EMA). The described protocols may help analysts to develop sample preparation methods in the field of therapeutic protein analysis. Copyright © 2017 Elsevier B.V. All rights reserved.

siRNAs that specifically silence the expression of cancer-related genes offer a therapeutic approach in oncology. However, it remains critical to determine the true mechanism of their therapeutic effects. Here, we describe the preclinical development of chemically modified siRNA targeting the essential cell-cycle proteins polo-like kinase 1 (PLK1) and kinesin spindle protein (KSP) in mice. siRNA formulated in stable nucleic acid lipid particles (SNALP) displayed potent antitumor efficacy in both hepatic and subcutaneous tumor models. This was correlated with target gene silencing following a single intravenous administration that was sufficient to cause extensive mitotic disruption and tumor cell apoptosis. Our siRNA formulations induced no measurable immune response, minimizing the potential for nonspecific effects. Additionally, RNAi-specific mRNA cleavage products were found in tumor cells, and their presence correlated with the duration of target mRNA silencing. Histological biomarkers confirmed that RNAi-mediated gene silencing effectively inhibited the target's biological activity. This report supports an RNAi-mediated mechanism of action for siRNA antitumor effects, suggesting a new methodology for targeting other key genes in cancer development with siRNA-based therapeutics.

Plant Proteinase Inhibitors in Therapeutics – Focus on Cancer Therapy

Full Text Available Plants are known to have many secondary metabolites and phytochemical compounds which are highly explored at biochemical and molecular genetics level and exploited enormously in the human health care sector. However, there are other less explored small molecular weight proteins, which inhibit proteases/proteinases. Plants are good sources of protease inhibitors (PIs which protect them against diseases, insects, pests, and herbivores. In the past, proteinaceous PIs were considered primarily as protein-degrading enzymes. Nevertheless, this view has significantly changed and PIs are now treated as very important signaling molecules in many biological activities such as inflammation, apoptosis, blood clotting and hormone processing. In recent years, PIs have been examined extensively as therapeutic agents, primarily to deal with various human cancers. Interestingly, many plant-based PIs are also found to be effective against cardiovascular diseases, osteoporosis, inflammatory diseases and neurological disorders. Several plant PIs are under further evaluation in in vitro clinical trials. Among all types of PIs, Bowman-Birk inhibitors (BBI has been studied extensively in the treatment of many diseases, especially in the field of cancer prevention. So far, crops such as beans, potatoes, barley, squash, millet, wheat, buckwheat, groundnut, chickpea, pigeonpea, corn and pineapple have been identified as good sources of PIs. The PI content of such foods has a significant influence on human health disorders, particularly in the regions where people mostly depend on these kind of foods. These natural PIs vary in concentration, protease specificity, heat stability, and sometimes several PIs may be present in the same species or tissue. However, it is important to carry out individual studies to identify the potential effects of each PI on human health. PIs in plants make them incredible sources to determine novel PIs with specific pharmacological and

Therapeutic hypothermia is recommended for comatose adults after witnessed out-of-hospital cardiac arrest, but data about this intervention in children are limited. We conducted this trial of two targeted temperature interventions at 38 children's hospitals involving children who remained unconscious after out-of-hospital cardiac arrest. Within 6 hours after the return of circulation, comatose patients who were older than 2 days and younger than 18 years of age were randomly assigned to therapeutic hypothermia (target temperature, 33.0°C) or therapeutic normothermia (target temperature, 36.8°C). The primary efficacy outcome, survival at 12 months after cardiac arrest with a Vineland Adaptive Behavior Scales, second edition (VABS-II), score of 70 or higher (on a scale from 20 to 160, with higher scores indicating better function), was evaluated among patients with a VABS-II score of at least 70 before cardiac arrest. A total of 295 patients underwent randomization. Among the 260 patients with data that could be evaluated and who had a VABS-II score of at least 70 before cardiac arrest, there was no significant difference in the primary outcome between the hypothermia group and the normothermia group (20% vs. 12%; relative likelihood, 1.54; 95% confidence interval [CI], 0.86 to 2.76; P=0.14). Among all the patients with data that could be evaluated, the change in the VABS-II score from baseline to 12 months was not significantly different (P=0.13) and 1-year survival was similar (38% in the hypothermia group vs. 29% in the normothermia group; relative likelihood, 1.29; 95% CI, 0.93 to 1.79; P=0.13). The groups had similar incidences of infection and serious arrhythmias, as well as similar use of blood products and 28-day mortality. In comatose children who survived out-of-hospital cardiac arrest, therapeutic hypothermia, as compared with therapeutic normothermia, did not confer a significant benefit in survival with a good functional outcome at 1 year.

Inhalation administration, compared with intravenous administration, significantly enhances chemotherapeutic drug exposure to the lung tissue and may increase the therapeutic effect for pulmonary anticancer. However, further identification of cancer cells after lung deposition of inhaled drugs is necessary to avoid side effects on normal lung tissue and to maximize drug efficacy. Moreover, as the action site of the major drug was intracellular organelles, drug target to the specific organelle is the final key for accurate drug delivery. Here, we designed a novel multifunctional nanoparticles (MNPs) for pulmonary antitumor and the material was well-designed for hierarchical target involved lung tissue target, cancer cell target, and mitochondrial target. The biodistribution in vivo determined by UHPLC-MS/MS method was employed to verify the drug concentration overwhelmingly increasing in lung tissue through inhaled administration compared with intravenous administration. Cellular uptake assay using A549 cells proved the efficient receptor-mediated cell endocytosis. Confocal laser scanning microscopy observation showed the location of MNPs in cells was mitochondria. All results confirmed the intelligent material can progressively play hierarchical target functions, which could induce more cell apoptosis related to mitochondrial damage. It provides a smart and efficient nanocarrier platform for hierarchical targeting of pulmonary anticancer drug. So far, this kind of material for pulmonary mitochondrial-target has not been seen in other reports.

Full text: A number of radiopharmaceuticals may soon emerge into mainstream clinical oncology for palliative and therapeutic treatment for a variety of malignancies. These agents are characterized by high linear energy transfer particulate emissions. Dispensing and administration of these therapies on a regular basis pose a substantial radiation burden to staff, from direct g-emissions and from Bremsstrahlung (braking) radiations. In an effort to implement the ALARA principle, a multidisciplinary team was given the brief to design a system which permitted: (1) safe, sterile transfer of a nominated quantity of radiopharmaceutical into a shielded reservoir compatible with the infusion pump; (2) remote variation of volume and administration rate upon command; (3) purging of delivery system following administration of dose; (4) monitoring of and communication with patient during infusion; (5) use of TGA-approved delivery system. The final design centred around an Abbott 'Lifecare 5000' volumetric dual-channel intravenous infusion pump and featured: microprocessor control with mutiline LCD prompting display; remote operation of keypad by pneumatic actuator; CCTV monitoring of patient, pump and physiological data; delivery of therapy dose from a shielded vial; flushing of therapy vial by 'back-priming'; and full array of safety alarms (air in line, occlusion, empty vial, etc). Further developments include audio communication with patient and remote physiological monitoring

In order to treat malignant tumors in human body, a stereotactic gamma-ray whole-body therapeutic system has been developed. This system is a typical large mechatronics treatment machine. In this paper, its main working principles and characteristics are introduced. This system comprises a special gallows frame with an open vertical structure, a changeable collimator device by which the size of convergence center can be chosen, and a 3D treatment couch. A computer brings the couch to target position automatically. Therefore precise and dynamic rotary converging therapy for tumors located anywhere in the body has been realized. The system's performance has been proved in practice, which includes good curative effect, reliable automation, and safe and secure operation. (authors)

Topical administration of eye drops is the major route for drug delivery to the cornea. Orbital fat-derived stem cells (OFSCs) possess an in vitro corneal epithelial differentiation capacity. Both the safety and immunomodulatory ability of systemic OFSC transplantation were demonstrated in our previous work. In this study, we investigated the safety, therapeutic effect, and mechanism(s) of topical OFSC administration in an extensive alkali-induced corneal wound. Corneal injury was created by contact of a piece of 0.5 N NaOH-containing filter paper on the corneal surface of a male Balb/c mouse for 30 s. The area of the filter paper covered the central 70% or 100% of the corneal surface. OFSCs (2 × 10(5)) in 5 μl phosphate-buffered saline (PBS) were given by topical administration (T) twice a day or by two intralimbal (IL) injections in the right cornea, while 5 μl of PBS in the left cornea served as the control. Topical OFSCs promoted corneal re-epithelialization of both the limbal-sparing and limbal-involved corneal wounds. In the first three days, topical OFSCs significantly reduced alkali-induced corneal edema and stromal infiltration according to a histopathological examination. Immunohistochemistry and immunofluorescence staining revealed that transplanted cells were easily detectable in the corneal epithelium, limbal epithelium and stroma, but only some of transplanted cells at the limbal epithelium had differentiated into cytokeratin 3-expressing cells. OFSCs did not alter neutrophil (Ly6G) levels in the cornea, but significantly reduced macrophage (CD68) infiltration and inducible nitrous oxide synthetase (iNOS) production during acute corneal injury as quantified by a Western blot analysis. Continuous topical administration of OFSCs for seven days improved corneal transparency, and this was accompanied by diffuse stromal engraftment of transplanted cells and differentiation into p63-expressing cells at the limbal area.

The combination of liposomal doxorubicin (DXR) and confocal ultrasound (US) was investigated for the enhancement of drug delivery in a rat tumour model. The liposomes, based on the unsaturated phospholipid dierucoylphosphocholine, were designed to be stable during blood circulation in order to maximize accumulation in tumour tissue and to release drug content upon US stimulation. A confocal US setup was developed for delivering inertial cavitation to tumours in a well-controlled and reproducible manner. In vitro studies confirm drug release from liposomes as a function of inertial cavitation dose, while in vivo pharmacokinetic studies show long blood circulation times and peak tumour accumulation at 24-48 h post intravenous administration. Animals injected 6 mg kg(-1) liposomal DXR exposed to US treatment 48 h after administration show significant tumour growth delay compared to control groups. A liposomal DXR dose of 3 mg kg(-1), however, did not induce any significant therapeutic response. This study demonstrates that inertial cavitation can be generated in such a fashion as to disrupt drug carrying liposomes which have accumulated in the tumour, and thereby increase therapeutic effect with a minimum direct effect on the tissue. Such an approach is an important step towards a therapeutic application of cavitation-induced drug delivery and reduced chemotherapy toxicity.

Little is known about the determining factors related to the administration of continuous palliative sedation. Knowledge of these determinants may assist physicians in identifying patients who are at high risk of developing refractory symptoms, enable physicians to inform patients, and optimize close monitoring. The aim of this systematic review was to identify determinants of the administration of continuous palliative sedation. A systematic review of PubMed, EMBASE, and CINAHL was performed to identify English, Dutch, and German language papers published from January 1990 through April 2011. Inclusion was based on the following criteria: patient-based research on continuous palliative sedation, studies investigating determinants of palliative sedation and/or comparison between sedated and nonsedated cohorts, and studies using multivariate analyses and of fair to good or good methodological quality. In total, eight papers were reviewed. The following nine factors were found to be associated with the administration of continuous palliative sedation: younger age, male sex, having cancer, feelings of hopelessness, dying in a hospital, living in a Dutch speaking community setting, very nonreligious or extremely nonreligious physicians, physicians working in "other hospital" specialties, and physicians in favor of assisted death. Given the variation in study designs and the limitations of the included studies, the outcomes should be interpreted carefully. Further research is needed, particularly regarding factors that can be influenced and that may alter the course of a patient's symptoms and the patient's eventual need for palliative sedation.

Achieving the Promise of Therapeutic Extracellular Vesicles: The Devil is in Details of Therapeutic Loading.

Science.gov (United States)

Sutaria, Dhruvitkumar S; Badawi, Mohamed; Phelps, Mitch A; Schmittgen, Thomas D

2017-05-01

Extracellular vesicles (EVs) represent a class of cell secreted organelles which naturally contain biomolecular cargo such as miRNA, mRNA and proteins. EVs mediate intercellular communication, enabling the transfer of functional nucleic acids from the cell of origin to the recipient cells. In addition, EVs make an attractive delivery vehicle for therapeutics owing to their increased stability in circulation, biocompatibility, low immunogenicity and toxicity profiles. EVs can also be engineered to display targeting moieties on their surfaces which enables targeting to desired tissues, organs or cells. While much has been learned on the role of EVs as cell communicators, the field of therapeutic EV application is currently under development. Critical to the future success of EV delivery system is the description of methods by which therapeutics can be successfully and efficiently loaded within the EVs. Two methods of loading of EVs with therapeutic cargo exist, endogenous and exogenous loading. We have therefore focused this review on describing the various published approaches for loading EVs with therapeutics.

Protein and Peptide in Drug Targeting and its Therapeutic Approach

Raj K. Keservani

2015-09-01

Full Text Available Aim: The main aim of this review article is to provide information like advantages of protein and peptides via different routes of drug administration, targeted to a particular site and its implication in drug delivery system. Methods: To that aim, from the web sites of PubMed, HCAplus, Thomson, and Registry were used as the main sources to perform the search for the most significant research articles published on the subject. The information was then carefully analyzed, highlighting the most important results in the development of protein and peptide drug targeting as well as its therapeutic activity. Results: In recent years many researchers use protein and peptide as a target site of drug by a different delivery system. Proteins and peptides are used as specific and effective therapeutic agents, due to instability and side effects their use is complicated. Protein kinases are important regulators of most, if not all, biological processes. Abnormal activity of proteins and peptides has been implicated in many human diseases, such as diabetes, cancer and neurodegenerative disorders. Conclusions: It is concluded that the protein and peptide were used in drug targeting to specific site and also used in different diseased states like cancer, diabetes, immunomodulating, neurodegenerative effects and antimicrobial activity.

Leber hereditary optic neuropathy (LHON) is currently estimated as the most frequent mitochondrial disease (1 in 27,000-45,000). Its molecular pathogenesis and natural history is now fairly well understood. LHON also is the first mitochondrial disease for which a treatment has been approved (idebenone-Raxone, Santhera Pharmaceuticals) by the European Medicine Agency, under exceptional circumstances because of the rarity and severity of the disease. However, what remains unclear includes the optimal target population, timing, dose, and frequency of administration of idebenone in LHON due to lack of accepted definitions, criteria, and general guidelines for the clinical management of LHON. To address these issues, a consensus conference with a panel of experts from Europe and North America was held in Milan, Italy, in 2016. The intent was to provide expert consensus statements for the clinical and therapeutic management of LHON based on the currently available evidence. We report the conclusions of this conference, providing the guidelines for clinical and therapeutic management of LHON.

Return on research investments: personal good versus public good

Science.gov (United States)

Fox, P. A.

2017-12-01

For some time the outputs, i.e. what's produced, of publicly and privately funded research while necessary, are far from sufficient, when considering an overall return on (research) investment. At the present time products such as peer-reviewed papers, websites, data, and software are recognized by funders on timescales related to research awards and reporting. However, from a consumer perspective impact and value are determined at the time a product is discovered, accessed, assessed and used. As is often the case, the perspectives of producer and consumer communities can be distinct and not intersect at all. We contrast personal good, i.e. credit, reputation, with that of public good, e.g. interest, leverage, exploitation, and more. This presentation will elaborate on both the metaphorical and idealogical aspects of applying a "return on investment" frame for the topic of assessing "good".

Oxidation of urate by a therapeutic nitric oxide/air mixture

Hicks, M.; Nguyen, L.; Day, R.; Rogers, P.

1996-01-01

Full text: Little is known about the potential toxicological consequences of therapeutic exposure of lung tissue to inhaled nitric oxide (NO). This route of administration is currently being successfully employed for the treatment of pulmonary hypertension and other lung pathologies including acute reperfusion injury in lung transplant patients. The toxicity of NO lies in its ability to act as an oxidant either in its own right or in concert with oxygen or with the superoxide free radical. One important interaction may be the reaction of these products with protective antioxidants in the lung epithelial lining fluid. One such antioxidant found in significant concentrations in both upper and lower airways is uric acid. In the present study, urate solutions (30μM) were exposed to a therapeutic concentration of NO gas, (35 ppm in air), for up to 90 minutes. Oxidative changes were followed spectrophotometrically and by HPLC. Significant loss of uric acid was observed with a concomitant formation of nitrite and allantoin, the stable oxidation product of NO and the major oxidation product of uric acid, respectively. No oxidation of urate was observed in the presence of air alone or when urate was incubated with nitrite. Uric acid oxidation could also be prevented by passing the NO / air stream through 10% KOH before the uric acid solution. This strategy removed trace amounts of higher oxides of nitrogen, (especially NO 2 ), from the NO / air stream. Thus, therapeutic inhalation of NO may deplete soluble antioxidants such as uric acid, especially during long-term chronic exposure unless care is taken to minimise formation of higher oxides of nitrogen

Reactor-produced therapeutic radioisotopes

International Nuclear Information System (INIS)

Knapp, F.F. Jr.

2002-01-01

The significant worldwide increase in therapeutic radioisotope applications in nuclear medicine, oncology and interventional cardiology requires the dependable production of sufficient levels of radioisotopes for these applications (Reba, 2000; J. Nucl. Med., 1998; Nuclear News, 1999; Adelstein and Manning, 1994). The issues associated with both accelerator- and reactor-production of therapeutic radioisotopes is important. Clinical applications of therapeutic radioisotopes include the use of both sealed sources and unsealed radiopharmaceutical sources. Targeted radiopharmaceutical agents include those for cancer therapy and palliation of bone pain from metastatic disease, ablation of bone marrow prior to stem cell transplantation, treatment modalities for mono and oligo- and polyarthritis, for cancer therapy (including brachytherapy) and for the inhibition of the hyperplastic response following coronary angioplasty and other interventional procedures (For example, see Volkert and Hoffman, 1999). Sealed sources involve the use of radiolabeled devices for cancer therapy (brachytherapy) and also for the inhibition of the hyperplasia which is often encountered after angioplasty, especially with the exponential increase in the use of coronary stents and stents for the peripheral vasculature and other anatomical applications. Since neutron-rich radioisotopes often decay by beta decay or decay to beta-emitting daughter radioisotopes which serve as the basis for radionuclide generator systems, reactors are expected to play an increasingly important role for the production of a large variety of therapeutic radioisotopes required for these and other developing therapeutic applications. Because of the importance of the availability of reactor-produced radioisotopes for these applications, an understanding of the contribution of neutron spectra for radioisotope production and determination of those cross sections which have not yet been established is important.

The most used antibiotics in the ICU registered in the ENVIN-HELICS program from 1 April to 30 June 2015 were selected. In this period, 257 patients received antimicrobial treatment and 26 antibiotics were evaluated. Variables studied: A risk assessment of each antibiotic using the scale Risk Assessment Tool, of the National Patient Safety Agency, as well as pH, osmolarity, type of catheter recommended for administration, and compatibility and incompatibility with other antibiotics studied. Almost two-thirds (65.3%) of antibiotics had more than 3 risk factors (represented by a yellow stripe), with the remaining 34.7% of antibiotics having between 0 and 2 risk factors (represented by a green stripe). There were no antibiotics with 6 or more risk factors (represented by a red stripe). Most drugs needed reconstitution, additional dilution, and the use of part of the vial to administer the prescribed dose. More than half of the antibiotics studied had a moderate risk level; thus measures should be adopted in order to reduce it. The risk matrix is a useful tool for the assessment and detection of weaknesses associated with the preparation and administration of intravenous antibiotics. Copyright © 2016 SECA.

Scientific breakthroughs have often led to commercially viable patents mainly in the field of engineering. Commercialization in the field of medicine has been restricted mostly to machinery and engineering on the one hand and therapeutic drugs for common chronic ailments such as cough, cold, headache, etc, on the other. Sequencing of the human genome has attracted the attention of pharmaceutical companies and now biotechnology has become a goldmine for commercialization of products and processes. Recent advances in our understanding of basic biological processes have resulted in the opening of new avenues for treatment of human genetic diseases, especially single gene disorders. A significant proportion of human genetic disorders have been shown to be caused due to degradation of transcripts for specific genes through a process called nonsense mediated decay (NMD). The modulation of NMD provides a viable therapeutic option for treatment of several genetic disorders and therefore has been a good prospect for patenting and commercialization. In this review the molecular basis for NMD and attempts to treat genetic diseases which result from NMD are discussed.

Cannabis sativa is also popularly known as marijuana. It has been cultivated and used by man for recreational and medicinal purposes since many centuries. Study of cannabinoids was at bay for very long time and its therapeutic value could not be adequately harnessed due to its legal status as proscribed drug in most of the countries. The research of drugs acting on endocannabinoid system has seen many ups and downs in the recent past. Presently, it is known that endocannabinoids has role in pathology of many disorders and they also serve "protective role" in many medical conditions. Several diseases like emesis, pain, inflammation, multiple sclerosis, anorexia, epilepsy, glaucoma, schizophrenia, cardiovascular disorders, cancer, obesity, metabolic syndrome related diseases, Parkinson's disease, Huntington's disease, Alzheimer's disease and Tourette's syndrome could possibly be treated by drugs modulating endocannabinoid system. Presently, cannabinoid receptor agonists like nabilone and dronabinol are used for reducing the chemotherapy induced vomiting. Sativex (cannabidiol and THC combination) is approved in the UK, Spain and New Zealand to treat spasticity due to multiple sclerosis. In US it is under investigation for cancer pain, another drug Epidiolex (cannabidiol) is also under investigation in US for childhood seizures. Rimonabant, CB1 receptor antagonist appeared as a promising anti-obesity drug during clinical trials but it also exhibited remarkable psychiatric side effect profile. Due to which the US Food and Drug Administration did not approve Rimonabant in US. It sale was also suspended across the EU in 2008. Recent discontinuation of clinical trial related to FAAH inhibitor due to occurrence of serious adverse events in the participating subjects could be discouraging for the research fraternity. Despite some mishaps in clinical trials related to drugs acting on endocannabinoid system, still lot of research is being carried out to explore and establish

Glycogen synthase kinase-3: A promising therapeutic target for Fragile X Syndrome

Directory of Open Access Journals (Sweden)

Marjelo M. Mines

2011-11-01

Full Text Available Recent advances in understanding the pathophysiological mechanisms contributing to Fragile X Syndrome (FXS have increased optimism that drug interventions can provide significant therapeutic benefits. FXS results from inadequate expression of functional fragile X mental retardation protein (FMRP. FMRP may have several functions, but it is most well-established as an RNA-binding protein that regulates translation, and it is by this mechanism that FMRP is capable of affecting numerous cellular processes by selectively regulating protein levels. The multiple cellular functions regulated by FMRP suggest that multiple interventions may be required for reversing the effects of deficient FMRP. Evidence that inhibitors of glycogen synthase kinase-3 (GSK3 may contribute to the therapeutic treatment of FXS is reviewed here. In the mouse model of FXS, which lacks FMRP expression (FX mice, GSK3 is hyperactive in several brain regions. Furthermore, significant improvements in several FX-related phenotypes have been obtained in FX mice following the administration of lithium, and in some case other GSK3 inhibitors. These responses include normalization of heightened audiogenic seizure susceptibility and of hyperactive locomotor behavior, enhancement of passive avoidance learning retention and of sociability behaviors, and corrections of macroorchidism, neuronal spine density, and neural plasticity measured electrophysiologically as long term depression. A pilot clinical trial of lithium in FXS patients also found improvements in several measures of behavior. Taken together, these findings indicate that lithium and other inhibitors of GSK3 are promising candidate therapeutic agents for treating FXS.

Human error has been identified as a major source of ABO-incompatible blood transfusion which most often results from blood being given to the wrong patient. We present a case of inadvertent administration of ABO-incompatible blood to a 6-mo-old child who underwent congenital heart surgery and discuss the use of invasive therapeutic approaches. Invasive techniques included total circulatory arrest and large-volume exchange transfusion, along with conventional ultrafiltration and plasmapheresis, which could all be performed rapidly and effectively. The combination of standard pharmacologic therapies and alternative invasive techniques after a massive ABO-incompatible blood transfusion led to a favorable outcome in our patient.

Cyclic peptide therapeutics: past, present and future.

Zorzi, Alessandro; Deyle, Kaycie; Heinis, Christian

2017-06-01

Cyclic peptides combine several favorable properties such as good binding affinity, target selectivity and low toxicity that make them an attractive modality for the development of therapeutics. Over 40 cyclic peptide drugs are currently in clinical use and around one new cyclic peptide drug enters the market every year on average. The vast majority of clinically approved cyclic peptides are derived from natural products, such as antimicrobials or human peptide hormones. New powerful techniques based on rational design and in vitro evolution have enabled the de novo development of cyclic peptide ligands to targets for which nature does not offer solutions. A look at the cyclic peptides currently under clinical evaluation shows that several have been developed using such techniques. This new source for cyclic peptide ligands introduces a freshness to the field, and it is likely that de novo developed cyclic peptides will be in clinical use in the near future.

Co-administration of creatine and guanidinoacetic acid for augmented tissue bioenergetics: A novel approach?

Science.gov (United States)

Ostojic, Sergej M

2017-07-01

A confined absorption of exogenous creatine through creatine transporter (CRT1) seems to hamper its optimal uptake in bioenergetical deficits. Co-administration of guanidinoacetic acid (GAA) along with creatine could target other transport channels besides CRT1, and supremely improve cellular levels of creatine. This innovative approach might tackle tissues difficult to reach with conventional creatine interventions, providing a potentially more effective and safe mixture in clinical pharmacology and therapeutics.

During the last 10 years the European Medicines Agency (EMA) organized a number of workshops on modeling and simulation, working towards greater integration of modeling and simulation (M&S) in the development and regulatory assessment of medicines. In the 2011 EMA - European Federation of Pharmaceutical Industries and Associations (EFPIA) Workshop on Modelling and Simulation, European regulators agreed to the necessity to build expertise to be able to review M&S data provided by companies in their dossier. This led to the establishment of the EMA Modelling and Simulation Working Group (MSWG). Also, there was agreement reached on the need for harmonization on good M&S practices and for continuing dialog across all parties. The MSWG acknowledges the initiative of the EFPIA Model-Informed Drug Discovery and Development (MID3) group in promoting greater consistency in practice, application, and documentation of M&S and considers the paper is an important contribution towards achieving this objective. © 2017 The Authors CPT: Pharmacometrics & Systems Pharmacology published by Wiley Periodicals, Inc. on behalf of American Society for Clinical Pharmacology and Therapeutics.

Full Text Available Background. Tromethamine (THAM has been demonstrated to reduce intracranial pressure (ICP. Early consideration for THAM may reduce the need for other measures for ICP control. Objective. To describe 4 cases of early THAM therapy for ICP control and highlight the potential to avoid TH and paralytics and achieve reduction in sedation and hypertonic/hyperosmotic agent requirements. Methods. We reviewed the charts of 4 patients treated with early THAM for ICP control. Results. We identified 2 patients with aneurysmal subarachnoid hemorrhage (SAH and 2 with traumatic brain injury (TBI receiving early THAM for ICP control. The mean time to initiation of THAM therapy was 1.8 days, with a mean duration of 5.3 days. In all patients, after 6 to 12 hours of THAM administration, ICP stability was achieved, with reduction in requirements for hypertonic saline and hyperosmotic agents. There was a relative reduction in mean hourly hypertonic saline requirements of 89.1%, 96.1%, 82.4%, and 97.0% for cases 1, 2, 3, and 4, respectively, comparing pre- to post-THAM administration. Mannitol, therapeutic hypothermia, and paralytics were avoided in all patients. Conclusions. Early administration of THAM for ICP control could potentially lead to the avoidance of other ICP directed therapies. Prospective studies of early THAM administration are warranted.

Although RNA interference may become a novel therapeutic approach for cancer treatment, target-site accumulation of siRNA to achieve therapeutic dosage will be a major problem. Microneedle represents a better way to deliver siRNAs and we have evaluated for the first time the capability of a silicon microneedle array for delivery of Gapdh siRNA to the skin in vivo and the results showed that the microneedle arrays could effectively deliver siRNA to relevant regions of the skin noninvasively. For the further study in this field, we evaluated the efficacy of the injectable microneedle device for local delivery of siRNA to the mouse xenograft. The results presented here indicate that local administration of siRNA through injectable microneedle could effectively deliver siRNA into the tumor region, and inhibit tumor progression without major adverse effects.

"Everyone just ate good food": 'Good food' in Islamabad, Pakistan.

Science.gov (United States)

Hasnain, Saher

2018-08-01

In recent years, consumption of alternatively produced foods has increased in popularity in response to the deleterious effects of rapidly globalising and industrialised food systems. Concerns over food safety in relation to these changes may result from elevated levels of risk and changing perceptions associated with food production practices. This paper explores how the middle class residents of Islamabad, Pakistan, use the concept of 'good food' to reconnect themselves with nature, changing food systems, and traditional values. The paper also demonstrates how these ideas relate to those of organic, local, and traditional food consumption as currently used in more economically developed states in the Global North. Through research based on participant observation and semi-structured interviews, this paper illustrates that besides price and convenience, purity, freshness, association with specific places, and 'Pakistani-ness' were considered as the basis for making decisions about 'good food'. The results show that while individuals are aware of and have some access to imported organic and local food, they prefer using holistic and culturally informed concepts of 'good food' instead that reconnect them with food systems. I argue that through conceptualisations of 'good food', the urban middle class in Islamabad is reducing their disconnection and dis-embeddedness from nature, the food systems, and their social identities. The paper contributes to literature on food anxieties, reconnections in food geography, and 'good food' perceptions, with a focus on Pakistan. Copyright © 2018. Published by Elsevier Ltd.

Pharmacokinetics and skin concentrations of lincomycin after intravenous and oral administration to cats

Directory of Open Access Journals (Sweden)

Gabriela A. Albarellos

2013-10-01

Full Text Available The aim of the present study was to describe the plasma pharmacokinetic profile and skin concentrations of lincomycin after intravenous administration of a 15% solution and oral administration of 300 mg tablets at a dosing rate of 15 mg/kg to cats. Susceptibility of staphylococci (n = 31 and streptococci (n = 23 strains isolated from clinical cases was also determined. Lincomycin plasma and skin concentrations were determined by microbiological assay using Kocuria rhizophila ATCC 9341 as test microorganism. Susceptibility was established by the antimicrobial disc diffusion test. Individual lincomycin plasma concentration–time curves were analysed by a non-compartmental approach. After intravenous administration, volume of distribution, body clearance and elimination half-life were 0.97 L/kg ± 0.15 L/kg, 0.17 L/kg ± 0.06 L/h.kg and 4.20 h ± 1.12 h, respectively. After oral administration, peak plasma concentration, time of maximum plasma concentration and bioavailability were 22.52 µg/mL ± 10.97 µg/mL, 0.80 h ± 0.11 h and 81.78% ± 24.05%, respectively. Two hours after lincomycin administration, skin concentrations were 17.26 µg/mL ± 1.32 µg/mL (intravenous and 16.58 µg/mL ± 0.90 µg/mL (oral. The corresponding skin: plasma ratios were 2.08 ± 0.47 (intravenous and 1.84 ± 0.97 (oral. The majority of staphylococci and streptococci tested in this study were susceptible to lincosamides (87.09% and 69.56%, respectively. In conclusion, lincomycin administered orally at the assayed dose showed a good pharmacokinetic profile, with a long elimination half-life and effective skin concentration. Therefore, it could be a good first option for treating skin infections in cats.

The effect of the route administration on the distribution of radioiodinated OV-TL 3 F(ab') 2 was studied in Balb/c female mice with intraperitoneal or subcutaneous ovarian carcinoma xenografts. In the intraperitoneal tumour model in which both ascites and solid tumour deposits were present, intraperitoneal administration resulted in a lower estimated radiation dose to blood as compared with intravenous administration. In this model normalization to equal estimated radiation doses to blood for both routes of administration indicated that a twice as high estimated radiation dose can be guided to solid intraperitoneal tumour deposits following intraperitoneal administration. Evacuation of ascitic tumour cells prior to monoclonal antibody injection further increased the estimated radiation dose to solid intraperitoneal tumour deposits following intraperitoneal delivery. Following simultaneous intravenous and intraperitoneal injection of the monoclonal antibody, tissue uptake showed no relevant differences in the subcutaneous tumour model. Overall, the intraperitoneal route of administration was found to be the best choice for therapeutic delivery of iodine-131 labelled monoclonal antibodies. (orig.)

Amyotrophic lateral sclerosis (ALS) is a fatal neurological disease characterized by degeneration of upper and lower motor neurons. There are currently no clinically impactful treatments for this disorder. Death occurs 3-5 years after diagnosis, usually due to respiratory failure. ALS pathogenesis seems to involve several pathological mechanisms (i.e., oxidative stress, inflammation, and loss of the glial neurotrophic support, glutamate toxicity) with different contributions from environmental and genetic factors. This multifaceted combination highlights the concept that an effective therapeutic approach should counteract simultaneously different aspects: stem cell therapies are able to maintain or rescue motor neuron function and modulate toxicity in the central nervous system (CNS) at the same time, eventually representing the most comprehensive therapeutic approach for ALS. To achieve an effective cell-mediated therapy suitable for clinical applications, several issues must be addressed, including the identification of the most performing cell source, a feasible administration protocol, and the definition of therapeutic mechanisms. The method of cell delivery represents a major issue in developing cell-mediated approaches since the cells, to be effective, need to be spread across the CNS, targeting both lower and upper motor neurons. On the other hand, there is the need to define a strategy that could provide a whole distribution without being too invasive or burdened by side effects. Here, we review the recent advances regarding the therapeutic potential of stem cells for ALS with a focus on the minimally invasive strategies that could facilitate an extensive translation to their clinical application.

Two cases of "cannabis acute psychosis" following the administration of oral cannabis

2005-04-01

Full Text Available Abstract Background Cannabis is the most commonly used illegal drug and its therapeutic aspects have a growing interest. Short-term psychotic reactions have been described but not clearly with synthetic oral THC, especially in occasional users. Case presentations We report two cases of healthy subjects who were occasional but regular cannabis users without psychiatric history who developed transient psychotic symptoms (depersonalization, paranoid feelings and derealisation following oral administration of cannabis. In contrast to most other case reports where circumstances and blood concentrations are unknown, the two cases reported here happened under experimental conditions with all subjects negative for cannabis, opiates, amphetamines, cocaine, benzodiazepines and alcohol, and therefore the ingested dose, the time-events of effects on behavior and performance as well as the cannabinoid blood levels were documented. Conclusion While the oral route of administration achieves only limited blood concentrations, significant psychotic reactions may occur.

Medication non adherence in schizophrenia is a major cause of relapse and hospitalization and remains for clinicians an important challenge. This study investigates the associations between insight, therapeutic alliance, perceived trauma related to psychiatric treatment and medication adherence in patients with schizophrenia. In this multicenter study, 72 patients were assessed regarding symptomatology, self-reported adherence with medication, insight, medication side-effects, therapeutic alliance and perceived trauma related to psychiatric treatment. Structural Equation Modeling (SEM) was used to test predicted paths among these variables. The data fit a model in which medication adherence was directly predicted by insight, therapeutic alliance and perceived trauma related to psychiatric treatment. Perceived trauma moderates the role of insight on medication adherence. The final model showed good fit, based on four reliable indices. Greater adherence was correlated with higher insight, higher therapeutic alliance and lower perceived trauma. These three variables appear to be important determinants of patient's medication adherence. Medication adherence could be enhanced by reducing perceived trauma and by increasing insight. The need for mental health providers to acknowledge patients' potentially traumatic experience with psychiatric treatment and the need to encourage greater involvement in care are discussed.

Full Text Available Administration of endotracheal surfactant is potentially the main treatment for neonates suffering from RDS (Respiratory Distress Syndrome, which is followed by mechanical ventilation. Late and severe complications may develop as a consequence of using mechanical ventilation. In this study, conventional methods for treatment of RDS are compared with surfactant administration, use of mechanical ventilation for a brief period and NCPAP (Nasal Continuous Positive Airway Pressure, (INSURE method ((Intubation, Surfactant administration and extubation. A randomized clinical trial study was performed, including all newborn infants with diagnosed RDS and a gestational age of 35 weeks or less, who were admitted in NICU of Valiasr hospital. The patients were then divided randomly into two CMV (Conventional Mechanical Ventilation and INSURE groups. Surfactant administration and consequent long-term mechanical ventilation were done in the first group (CMV group. In the second group (INSURE group, surfactant was administered followed by a short-term period of mechanical ventilation. The infants were then extubated, and NCPAP was embedded. The comparison included crucial duration of mechanical ventilation and oxygen therapy, IVH (Intraventricular Hemorrhage, PDA (Patent Ductus Arteriosus, air-leak syndromes, BPD (Broncho-Pulmonary Dysplasia and mortality rate. The need for mechanical ventilation in 5th day of admission was 43% decreased (P=0.005 in INSURE group in comparison to CMV group. A decline (P=0.01 in the incidence of IVH and PDA was also achieved. Pneumothorax, chronic pulmonary disease and mortality rates, were not significantly different among two groups. (P=0.25, P=0.14, P=0.25, respectively. This study indicated that INSURE method in the treatment of RDS decreases the need for mechanical ventilation and oxygen-therapy in preterm neonates. Moreover, relevant complications as IVH and PDA were observed to be reduced. Thus, it seems rationale to

In some recent papers I have been arguing that the concept ‘good-for’ is prior to the concept of ‘good’ (in the sense in which final ends are good), and exploring the implications of that claim. One of those implications is that everything that is good is good for someone. That implication seems to fall afoul of our intuitions about certain cases, such as the intuition that a world full of happy people and animals is better than a world full of miserable ones, even if the people and animals a...

The objective of the present study was to investigate hospital administrator's expectations about the administrative role played by nurses, utilizing functions proposed by the Neoclassical Theory of Administration: planning, organization, direction, and control as theoretical references. An instrument established in TREVIZAN (1989) was applied to 11 hospital administrators. The results showed they expect the four functions to be done by nurses. Therefore, the interaction between nurses and hospital administrators is critical to improve the patient's assistance.

This study aims to analyze the variables on which depends therapeutic discharge, in patients with a severe dual diagnosis admitted to a professional therapeutic community where their pathology is treated. 325 patients admitted between June 2000 and June 2009 to the therapeutic community. This is a retrospective, cross-sectional study with no control group, based on the detailed analysis of the information collected in a model of semi-structured clinical interview designed in the therapeutic community. The 29.5% of the individuals included in the sample were therapeutically discharged. Of all the variables introduced in this analysis the most significant ones were gender, age at the beginning of treatment, education level, opiate dependence, polidrug abuse, and the presence of psychotic disorders and borderline personality disorder. In our study, gender determines the type of discharge, being therapeutic discharge more frequent among women. A higher educational also increases a better prognosis with a higher rate of therapeutic discharge among individuals with higher education level. A later age at the beginning of the treatment reduces the likelihood of therapeutic discharge. Likewise, polidrug abuse, diagnosis of psychotic disorders and borderline personality disorder are associated to a lower rate of therapeutic discharge. Recognizing these characteristics will allow the early identification of those patients more at risk of dropping treatment hastily, while trying to prevent it by increasing the therapeutic intensity.

2018-05-01

The 'good death' is one objective of palliative care, with many 'good death' viewpoints and research findings reflecting the urban voice. Rural areas are distinct and need special consideration. This scoping review identified and charted current research knowledge on the 'good' rural death through the perspectives of rural residents, including rural patients with a life-limiting illness, to identify evidence and gaps in the literature for future studies. A comprehensive literature search of English language articles (no date filter applied) was conducted in 2016 (2 January to 14 February) using five library databases. Reference lists of included articles, recent issues of eight relevant journals and three grey literature databases were also hand-searched. Twenty articles (for 17 studies and one systematic review) were identified after a two-phase screening process by two reviewers, using pre-determined inclusion criteria. Data from each study were extracted and charted, analysed using a thematic analysis of the included articles' content, and with a quantitative analysis of the scoping review. These papers revealed data collected from rural patients with a life-limiting illness and family caregivers, rural healthcare providers, the wider rural community, rural community leaders and rural health administrators and policy makers. Rural locations were heterogeneous. Residents from developed and developing countries believe a 'good death' is one that is peaceful, free of pain and without suffering; however, this is subjective and priorities are based on personal, cultural, social and religious perspectives. Currently, there is insufficient data to generalise rural residents' perspectives and what it means for them to die well. Given the extreme importance of a 'good death', there is a need for further studies to elicit rural patient and family caregiver perspectives. © 2016 John Wiley & Sons Ltd.

Have you noticed when you browse a book, journal, study report, or product label how your eye is drawn to figures more than to words and tables? Statistical graphs are powerful ways to transparently and succinctly communicate the key points of medical research. Furthermore, the graphic design itself adds to the clarity of the messages in the data. The goal of this paper is to provide a mechanism for selecting the appropriate graph to thoughtfully construct quality deliverables using good graphic design principles. Examples are motivated by the efforts of a Safety Graphics Working Group that consisted of scientists from the pharmaceutical industry, Food and Drug Administration, and academic institutions.

Abdominal free flaps for microsurgical breast reconstruction are most commonly harvested based on the deep inferior epigastric vessels that supply skin and fat via perforators through the rectus muscle and sheath. Intact perforator anatomy and connections are vital for subsequent optimal flap perfusion and avoidance of necrosis, be it partial or total. The intraflap vessels are delicate and easily damaged and it is generally advised that patients should avoid heparin injection into the abdominal pannus preoperatively as this may compromise the vascular perforators through direct needle laceration, pressure from bruising, haematoma formation, or perforator thrombosis secondary to external compression. We report three cases of successful deep inferior epigastric perforator (DIEP) flap harvest despite patients injecting therapeutic doses of low molecular weight heparin into their abdomens for thrombosed central venous lines (portacaths™) used for administering primary chemotherapy in breast cancer.

Therapeutic applications of radiopharmaceuticals

Baker, W.J.; Datz, F.L.; Beightol, R.W.

1987-01-01

Whether a radiopharmaceutical has diagnostic or therapeutic application depends on both the isotope and pharmaceutical used. For diagnostic applications, the isotope should undergo only γ-decay, since usually only γ-radiation is detected by nuclear medicine cameras. The half-life should be just long enough to allow the procedure to be performed. In contrast, the isotope needed for therapeutic purposes should have particulate radiation, such as a β-particle (electron), since these are locally absorbed an increase the local radiation dose. γ-Radiation, which penetrates the tissues, produces less radiation dose than do Β-particles. Several references dealing with radioactive decay, particulate interactions, and diagnostic and therapeutic applications of radiopharmaceuticals are available. Radiopharmaceuticals can legally be used only by physicians who are qualified by specific training in the safe handling of radionuclides. The experience and training of these physicians must be approved by the Nuclear Regulatory Commission or Agreement State Agency authorized to license the use of radiopharmaceuticals. A list of all byproduct material and procedures is available in the Code of Federal Regulations. Of the many radiopharmaceuticals available for diagnostic and therapeutic use, only those commonly used are discussed in this chapter

Objective: To explore the characteristic of operation, intra-operation treatment and the application of immunosuppressant in pediatric renal transplantation in order to improve therapeutic effectiveness. Methods: From March 1986 to October 2006, the clinical data of 63 children who underwent renal transplantation in our hospital were retrospectively analyzed. Results: The 1-, 3-, 5-, 10-year graft survival rates were 98.4%, 90.5%, 88.9% and 68.3%,respectively. And the corresponding patient survival rates were 100%, 95.2%, 92.1%, 71.4%. The body weight increased 4 to 12 kg and the body height grew up 2 to 6 cm during the first year post-transplantation. The main complications in the first year post-transplantation were hypertension (26/63, 41.3%), crinosity (14/63, 22.2%),drug-induced hepatic injury(11/63, 17.5%), gingival hyperplasia (10/63, 15.8%), pulmonary infection(9/63, 14.3%),bone marrow suppression(5/63, 7.9%), herpes (4/63, 6.3%) and diabetes (3/63, 4.8%). Conclusion: Renal transplantation is a preferred method for the treatment of children in end-stage renal disease (ESRD). Good tissue matching, proper operative time and pattern, peri-operactive care were essential to success, as well as appropriate immuno-suppressant strategy and good compliance.

In radioiodine therapy of benign thyroid disease, a reduction of radioiodine uptake is known for consecutive administrations of 131I, which needs to be considered in therapy planning. Aim: Analysis of uptake reduction with regard on the time interval between radioiodine administration and the delivered dose to the thyroid tissue. Patients, methods: 200 patients were enrolled in the study and distributed into two groups (matched for diagnoses), each containing 32 patients with Graves' disease (target dose 250 Gy), 24 with focal (400 Gy), 44 with disseminated thyroid autonomy (150 Gy). In one group, a second fraction of radioiodine was given after 48 h (2d) due to an unexpected low radioiodine uptake or effective half-life, whereas in the other group the second fraction was given after 96 h (4d). Results: There was no significant difference between delivered doses due to the first fraction after four days: 2d: 86 ± 48 Gy (extrapolated) vs. 4d: 87 ± 41 Gy, p > 0.05. In 2d, delivered dose at time of second administration was significantly lower (51 μ 29 Gy) than in 4d (p < 0.01). The radioiodine uptake of the second fraction relative to the initial uptake was significantly lower in the 4d (4d: 63 ± 25% vs. 2d: 82 ± 24%, p < 0.01). In addition, a correlation between uptake reduction and delivered dose and an influence of the time interval between radioiodine administrations could be shown. Conclusions: Relative uptake of subsequent radioiodine fractions decreases with time after first administration and with increasing delivered dose to the thyroid. If a second fraction of 131I is given at an earlier time, the same therapeutic effect can be reached using lower amounts of activity, minimising radiation exposure and increasing efficiency of radioiodine therapy.

What is good governance in the context of drug policy?

Singleton, Nicola; Rubin, Jennifer

2014-09-01

The concept of governance is applied in a wide range of contexts, but this paper focuses on governance in relation to public administration, i.e. states and how they take action, and specifically governance of particular policy areas. In the current context of financial austerity and an era of globalisation, policy-makers face pressures and challenges from a growing range of interests and local, national and supranational actors. Drug policy is an example of a particularly contentious and polarised area in which governance-related challenges abound. In response to these challenges, interest has grown in developing agreed policy governance standards and processes and articulating policy-making guidelines, including the use of available evidence to inform policy-making. Attempts have been made to identify 'policy fundamentals' - factors or aspects of policy-making apparently associated with successful policy development and implementation (Hallsworth & Rutter, 2011; Laughrin, 2011) and, in the drug policy field, Hughes et al. (2010) reflecting on the co-ordination of Australian drug policy highlighted some of what they considered principles of good governance. But how useful is the concept of 'good governance'; how well can it be defined, and to what purpose? As part of a wider project considering the governance of drug policy, RAND Europe and the UK Drug Policy Commission undertook a targeted review of other research and sought expert views, from within and beyond drug policy, on principles, processes, structures and stakeholders associated with good drug policy governance. From this emerged some perceived characteristics of good governance that were then used by the UK Drug Policy Commission to assess the extent to which drug policy making in the UK fits with these perceived good governance characteristics, and to suggest possible improvements. Particular consideration was given to the range of interests at stake, the overarching aims of drug policy and the

Therapeutic implications of curcumin in the prevention of diabetic retinopathy via modulation of anti-oxidant activity and genetic pathways

Diabetic Retinopathy (DR) is one of the most common complications of diabetes mellitus that affects the blood vessels of the retina, leading to blindness. The current approach of treatment based on anti-inflammatory, anti-angiogenesis drugs and laser photocoagulation are effective but also shows adverse affect in retinal tissues and that can even worsen the visual abilities. Thus, a safe and effective mode of treatment is needed to control or delaying the DR. Based on the earlier evidence of the potentiality of natural products as anti-oxidants, anti-diabetic and antitumor, medicinal plants may constitute a good therapeutic approach in the prevention of DR. Curcumin, constituents of dietary spice turmeric, has been observed to have therapeutic potential in the inhibition or slow down progression of DR. In this review, we summarize the therapeutic potentiality of curcumin in the delaying the DR through antioxidant, anti-inflammatory, inhibition of Vascular Endothelial Growth and nuclear transcription factors. The strength of involvement of curcumin in the modulation of genes action creates a strong optimism towards novel therapeutic strategy of diabetic retinopathy and important mainstay in the management of diabetes and its complications DR.

Emil BALAN

2017-03-01

Full Text Available Clear, consistent and predictable rules applicable to the administrative activities of the EU institutions, as well as deepening the EU integration are crucial in order to create a European administrative space. Building on the need to achieving this goal, the paper analyses the object, the procedure applicable, the legal regime and the safeguards granted to whistleblowers, as well as the role of the whistleblowing as a preventive or risk mitigation mechanism for those situations in which noncompliance with the principles of administrative law may affect the validity of documents, the performance of the legal competencies of the institution or citizens` rights. It raises awareness on risks and costs of non-compliance with the principles of the administrative law and good administration standards, as well as on the vulnerabilities and effects it can generate. The document also places whistleblowing in the context of control mechanism available for verifying the compliance of concrete administrative activities with these principles, as a solution to identify and retrieve breaches from within the institution. To draw conclusions, this paper builds on the above analysis and the current Romanian good practice in the field, and frames a series of recommendations for improving the procedure applicable to whistleblowing.

'Spending My Own Money, Harming My Own Body': Addiction Care in a Chinese Therapeutic Community.

Science.gov (United States)

Hyde, Sandra Teresa

2017-01-01

In this article, I explore a Chinese residential therapeutic community I call Sunlight in order to understand its quotidian therapies, its fraught nature binding China's past with its future, and the to care for the self under postsocialism. Reviewing Sunlight ethnographically allows for broader theoretical exploration into how China's economic transition created tensions between capitalism, socialism, and communism; between individual and community, care and coercion, and discipline and freedom. Sunlight blended democratic, communal, and communist values that in several ways transition drug addicts into a market-socialist society. In focusing on the socialist transition to capitalism much work concentrates on the neoliberal transition as the only path out of communism rather than exploring its exceptions. In exploring China as an exception, I ask: What do the residents, peer-educators and administrators reveal in their stories and reactions to community-based therapeutics of care and what happens when their notions of care clash?

Esensten, Jonathan H; Bluestone, Jeffrey A; Lim, Wendell A

2017-01-24

Engineered T cells are currently in clinical trials to treat patients with cancer, solid organ transplants, and autoimmune diseases. However, the field is still in its infancy. The design, and manufacturing, of T cell therapies is not standardized and is performed mostly in academic settings by competing groups. Reliable methods to define dose and pharmacokinetics of T cell therapies need to be developed. As of mid-2016, there are no US Food and Drug Administration (FDA)-approved T cell therapeutics on the market, and FDA regulations are only slowly adapting to the new technologies. Further development of engineered T cell therapies requires advances in immunology, synthetic biology, manufacturing processes, and government regulation. In this review, we outline some of these challenges and discuss the contributions that pathologists can make to this emerging field.

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

Papillary thyroid cancer is often described as the "good cancer" because of its treatability and relatively favorable survival rates. This study sought to characterize the thoughts of papillary thyroid cancer patients as they relate to having the "good cancer." This qualitative study included 31 papillary thyroid cancer patients enrolled in an ongoing randomized trial. Semi-structured interviews were conducted with participants at the preoperative visit and two weeks, six weeks, six months, and one year after thyroidectomy. Grounded theory was used, inductively coding the first 113 interview transcripts with NVivo 11. The concept of thyroid cancer as "good cancer" emerged unprompted from 94% (n = 29) of participants, mostly concentrated around the time of diagnosis. Patients encountered this perception from healthcare providers, Internet research, friends, and preconceived ideas about other cancers. While patients generally appreciated optimism, this perspective also generated negative feelings. It eased the diagnosis of cancer but created confusion when individual experiences varied from expectations. Despite initially feeling reassured, participants described feeling the "good cancer" characterization invalidated their fears of having cancer. Thyroid cancer patients expressed that they did not want to hear that it's "only thyroid cancer" and that it's "no big deal," because "cancer is cancer," and it is significant. Patients with papillary thyroid cancer commonly confront the perception that their malignancy is "good," but the favorable prognosis and treatability of the disease do not comprehensively represent their cancer fight. The "good cancer" perception is at the root of many mixed and confusing emotions. Clinicians emphasize optimistic outcomes, hoping to comfort, but they might inadvertently invalidate the impact thyroid cancer has on patients' lives.

Tetrodotoxin (TTX as a Therapeutic Agent for Pain

Directory of Open Access Journals (Sweden)

Cruz Miguel Cendán

2012-01-01

Full Text Available Tetrodotoxin (TTX is a potent neurotoxin that blocks voltage-gated sodium channels (VGSCs. VGSCs play a critical role in neuronal function under both physiological and pathological conditions. TTX has been extensively used to functionally characterize VGSCs, which can be classified as TTX-sensitive or TTX-resistant channels according to their sensitivity to this toxin. Alterations in the expression and/or function of some specific TTX-sensitive VGSCs have been implicated in a number of chronic pain conditions. The administration of TTX at doses below those that interfere with the generation and conduction of action potentials in normal (non-injured nerves has been used in humans and experimental animals under different pain conditions. These data indicate a role for TTX as a potential therapeutic agent for pain. This review focuses on the preclinical and clinical evidence supporting a potential analgesic role for TTX. In addition, the contribution of specific TTX-sensitive VGSCs to pain is reviewed.

The growing advance of new technologies in Nuclear Medicine such as positron emission tomography (PET) allows visualizing biological processes in vivo and provides more sensitive results in the diagnosis of oncological processes in asymptomatic stages of the disease and contribute significantly to improve cancer management. It is significant to note that these technologies include radiopharmaceuticals marked with 90 Y and 177 Lu for the therapy of patients already diagnosed by the PET technique that contribute to a significant improvement in the quality of life of patients with cancer. Our country, taking into account the importance of this technology for Health, has developed in INOR a project for the obtaining, dispensing and quality control of PET radiopharmaceuticals marked with 68 Ga for diagnosis and its therapeutic analogues marked with 177 Lu and 90Y in Conditions of Good Manufacturing Practices (GMP). The objective of the present work is to present our experiences in the implementation of the Good Practices of Manufacture of PET Radiopharmaceuticals according to regulation 16-2012 GUIDELINES ON GOOD PRACTICES OF MANUFACTURE OF PHARMACEUTICAL PRODUCTS, issued by the State Control Center for Medicines, Equipment and Devices Doctors (CECMED), a Cuban regulatory body. The implementation of the regulation considers from the preparation of personnel involved in the activity, moving through the facilities and equipment to the validation and quality control. A system for the quality assurance of the production of PET radiopharmaceuticals was implemented in accordance with Annex 5 of Regulation 16-2012 of the CECMED. This is the first experience in Cuba of the implementation of Good Manufacturing Practices of PET Radiopharmaceuticals in Hospital Radiopharmacy. The acquired experiences will be extended to the practices for the preparation of radiopharmaceuticals for the conventional Nuclear Medicine in the INOR.

Highlights: •Blockade of the ERK pathway enhances the anticancer efficacy of HDAC inhibitors. •MEK inhibitors sensitize human tumor xenografts to HDAC inhibitor cytotoxicity. •Such the enhanced efficacy is achieved by a transient blockade of the ERK pathway. •This drug combination provides a promising therapeutic strategy for cancer patients. -- Abstract: The ERK pathway is up-regulated in various human cancers and represents a prime target for mechanism-based approaches to cancer treatment. Specific blockade of the ERK pathway alone induces mostly cytostatic rather than pro-apoptotic effects, however, resulting in a limited therapeutic efficacy of the ERK kinase (MEK) inhibitors. We previously showed that MEK inhibitors markedly enhance the ability of histone deacetylase (HDAC) inhibitors to induce apoptosis in tumor cells with constitutive ERK pathway activation in vitro. To evaluate the therapeutic efficacy of such drug combinations, we administered the MEK inhibitor PD184352 or AZD6244 together with the HDAC inhibitor MS-275 in nude mice harboring HT-29 or H1650 xenografts. Co-administration of the MEK inhibitor markedly sensitized the human xenografts to MS-275 cytotoxicity. A dose of MS-275 that alone showed only moderate cytotoxicity thus suppressed the growth of tumor xenografts almost completely as well as induced a marked reduction in tumor cellularity when administered with PD184352 or AZD6244. The combination of the two types of inhibitor also induced marked oxidative stress, which appeared to result in DNA damage and massive cell death, specifically in the tumor xenografts. The enhanced therapeutic efficacy of the drug combination was achieved by a relatively transient blockade of the ERK pathway. Administration of both MEK and HDAC inhibitors represents a promising chemotherapeutic strategy with improved safety for cancer patients.

Objectives: To evaluate the usefulness of administration of superparamagnetic iron oxide (SPIO) and magnetic resonance (MR) imaging for assessing the efficacy of radiofrequency (RF) liver ablation. Material and methods: Using a protocol approved by the animal research committee of our university, nine RF liver ablations were performed in three miniature pigs. Six ablations were performed after administration of SPIO in two pigs (group A). Three ablations were performed in the other pig without administration of SPIO (group B). All pigs were sacrificed 4 days after the procedure. Harvested livers were scanned with a 1.5 T MR system before and after fixation with 10% buffered formalin, and MR images were precisely compared with histological specimens. Results: There were no histological differences between the two groups. All ablated liver lesions showed coagulation necrosis at the external layer. There were no viable cells inside the coagulation necrosis. All ablated lesions had a hypointense rim on fast low angle shot (FLASH) images. The rims of group A were thicker than those of group B. The rims of group B corresponded histologically to congestion and hemorrhagic necrosis area. The rims of the group A corresponded to hemorrhagic necrosis and coagulation necrosis areas. In group A, the hypointense rim reflected necrotic Kupffer cells that took up SPIO before RF liver ablation. Conclusion: Administration of SPIO made it possible to precisely evaluate ablated liver parenchyma by hypointense rim on FLASH images. This method is helpful for the evaluation of safety margin after RF ablation for liver tumors.

Infection stones have an outstanding position in childhood urolithiasis. In non-infection stones one can mostly find a certain--for example metabolic--causes of stone formation. In infection stones, the urease-producing and thus urea-cleaving properties of some gram-negative bacteria are responsible for alkalization of the urine and lead especially in combination with disturbances of urine transport to the staghorn calculi. Therefore in such children early diagnosis, adequate therapy and consequent maintenance is the crucial point for good life quality in future. Preliminary condition for therapeutic success is a close coworking between pediatric nephrologist, pediatric urologist, family doctor and parents.

PARTICULARITIES OF THE ORGANIZATION OF LOCAL PUBLIC ADMINISTRATION IN ROMANIAN AND GREEK SPACES

Full Text Available The way the public administration is organized affects the progress of the national community, in general, and of the local communities, in particular. A good management of public affairs from territorial units is not possible without the organizational design of the local administrative mechanism. From such a way, the pages of this paper are devoted to the study in mirror of the organization way of the Romanian and Greek local administrative systems, both territorially and functionally. By examining the territorial and functional administrative organisation we highlighted the peculiarities encountered and we extracted the similarities and the differences in the two local public administrations taken into consideration. As a result of the investigations conducted we found that at the basis of both local administrations are found clear regulations that expressly provide the territorial and functional organisational bases; with reference to the territorial organisation, for both administrative systems we have identified a structure with three levels of government, the difference being given by the existence of other specific territorial divisions; regarding the organs through which is realised the management of public affairs, in both administrations we find own authorities for each of the levels of government; the duration of the mandate of the Romanian local administration authorities differs from the one of the Greek administration authorities; most of administrative authorities of the two systems are elected by direct vote and only for some of them the setting occurs through indirect voting or appointment. Overall, we found that, at least regarding the criteria analyzed, between the two local public administrations there are no consistent differences, the territorial and functional organisational specificities being similar in equal measure.

Metabolic disorders, including obesity, diabetes, and cardiovascular disease, are widespread in Westernized nations. Gut microbiota composition is a contributing factor to the susceptibility of an individual to the development of these disorders; therefore, altering a person's microbiota may ameliorate disease. One potential microbiome-altering strategy is the incorporation of modified bacteria that express therapeutic factors into the gut microbiota. For example, N-acylphosphatidylethanolamines (NAPEs) are precursors to the N-acylethanolamide (NAE) family of lipids, which are synthesized in the small intestine in response to feeding and reduce food intake and obesity. Here, we demonstrated that administration of engineered NAPE-expressing E. coli Nissle 1917 bacteria in drinking water for 8 weeks reduced the levels of obesity in mice fed a high-fat diet. Mice that received modified bacteria had dramatically lower food intake, adiposity, insulin resistance, and hepatosteatosis compared with mice receiving standard water or control bacteria. The protective effects conferred by NAPE-expressing bacteria persisted for at least 4 weeks after their removal from the drinking water. Moreover, administration of NAPE-expressing bacteria to TallyHo mice, a polygenic mouse model of obesity, inhibited weight gain. Our results demonstrate that incorporation of appropriately modified bacteria into the gut microbiota has potential as an effective strategy to inhibit the development of metabolic disorders.

Over the past two decades, therapeutic antibodies have demonstrated promising results in the treatment of a wide array of diseases. However, the application of antibody-based therapy implies multiple administrations and a high cost of antibody production, resulting in costly therapy. Another disadvantage inherent to antibody-based therapy is the limited stability of antibodies and the low level of tissue penetration. The use of nanoparticles as delivery systems for antibodies allows for a reduction in antibody dosing and may represent a suitable alternative to increase antibody stability Areas covered: We discuss different nanocarriers intended for the delivery of antibodies as well as the corresponding encapsulation methods. Recent developments in antibody nanoencapsulation, particularly the possible toxicity issues that may arise from entrapment of antibodies into nanocarriers, are also assessed. In addition, this review will discuss the alterations in antibody structure and bioactivity that occur with nanoencapsulation. Expert opinion: Nanocarriers can protect antibodies from degradation, ensuring superior bioavailability. Encapsulation of therapeutic antibodies may offer some advantages, including potential targeting, reduced immunogenicity and controlled release. Furthermore, antibody nanoencapsulation may aid in the incorporation of the antibodies into the cells, if intracellular components (e.g. intracellular enzymes, oncogenic proteins, transcription factors) are to be targeted.

[End therapeutic nihilism towards COPD].

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

Full Text Available Public administration is classified into a specific organizational form that follows the development of all civilizations. Today, more than ever, we deal with creating a new model of public administration. The reform of public administration intends to achieve the model adjusted to the needs of society, based on lawful solutions, and real conditions. The EU integration process puts a pressure on public administration to deliver better service, with more and more demands to increase the skills of employees, to make performance of duties and tasks more effective, adhering to the principles of good governance. This paper presents a study of administrative body's organizational culture, based on the selected standpoint that the organizational culture is defined as a set of values, norms and beliefs in which the servants in administrative body share the same opinion. This brought ten characteristic values that can be shaped into the mission of observed local self-government (public administration unit. We tried to estimate through this research how civil servants perceive these ten values, and whether they like it or not.

Polycystic ovary syndrome (PCOS) is characterized by hormonal abnormalities that cause menstrual irregularity and reduce ovulation rate and fertility, associated to insulin resistance. Myo-inositol (cis-1,2,3,5-trans-4,6-cyclohexanehexol, MI) and D-chiro-inositol (cis-1,2,4-trans-3,5,6-cyclohexanehexol, DCI) represent promising treatments for PCOS, having shown some therapeutic benefits without substantial side effects. Because the use of inositols for treating PCOS is widespread, a deep understanding of this treatment option is needed, both in terms of potential mechanisms and efficacy. This review summarizes the current knowledge on the biological effects of MI and DCI and the results obtained from relevant intervention studies with inositols in PCOS. Based on the published results, both MI and DCI represent potential valid therapeutic approaches for the treatment of insulin resistance and its associated metabolic and reproductive disorders, such as those occurring in women affected by PCOS. Furthermore, the combination MI/DCI seems also effective and might be even superior to either inositol species alone. However, based on available data, a particular MI:DCI ratio to be administered to PCOS patients cannot be established. Further studies are then necessary to understand the real contents of MI or DCI uptaken by the ovary following oral administration in order to identify optimal doses and/or combination ratios.

Full Text Available Rhaya L Johnson,1 Christopher G Wilson1,2 1Lawrence D Longo MD Center for Perinatal Biology, Department of Basic Sciences, Loma Linda University, Loma Linda, CA, USA; 2Department of Pediatrics, Loma Linda University, Loma Linda, CA, USA Abstract: In this review, we provide an overview of the US Food and Drug Administration (FDA-approved clinical uses of vagus nerve stimulation (VNS as well as information about the ongoing studies and preclinical research to expand the use of VNS to additional applications. VNS is currently FDA approved for therapeutic use in patients aged >12 years with drug-resistant epilepsy and depression. Recent studies of VNS in in vivo systems have shown that it has anti-inflammatory properties which has led to more preclinical research aimed at expanding VNS treatment across a wider range of inflammatory disorders. Although the signaling pathway and mechanism by which VNS affects inflammation remain unknown, VNS has shown promising results in treating chronic inflammatory disorders such as sepsis, lung injury, rheumatoid arthritis (RA, and diabetes. It is also being used to control pain in fibromyalgia and migraines. This new preclinical research shows that VNS bears the promise of being applied to a wider range of therapeutic applications.

Illicit and therapeutic opioid administration can result in overdose due to opioid-induced respiratory depression. Research investigating the respiratory depressant effects of opioids has been limited due to difficulties associated with acquiring long-term respiratory data. This study examined the novel use of radiotelemetry to measure respiratory rate, heart rate, locomotor activity and blood pressure in rats treated chronically with methadone. Over 4 days of treatment, respiratory rate decreased, but partial tolerance appeared to develop during active (night) periods. Decreased heart rate was observed during the night periods and tolerance appeared to develop to this effect. Activity and blood pressure did not change with treatment. The effects of naloxone hydrochloride and naloxone methiodide administration on the methadone-treated rats were also examined and both antagonists increased respiratory rate and heart rate, with only naloxone hydrochloride producing significant increases in activity. Radiotelemetry offers a means of evaluating drug effects on respiratory rate continually in ambulatory, unstressed animals.
