The inaugural meeting of the Safety Pharmacology Society (SPS) was in 2001, soon after ICH S7A had been adopted. The 10th anniversary is an appropriate milestone at which to analyse trends in the science and themes of safety pharmacology, as reflected in posters presented at the annual meetings. The source information was the poster abstract booklets from each of the first ten annual meetings. The number of posters rose steadily from 34 in 2001 to 201 in 2010. The proportion of posters containing in vitro data has remained constant throughout the decade at ~30%. In terms of organ functions, themes relating to the cardiovascular system (CVS) have always generated the majority of posters, remaining above 60% of the total for the last 9years. The dominant theme has been around 'QT liability'. This peaked in 2003 at 68% of all posters presented, around the time of the ICHS7B discussions, and has remained above 30% thereafter. Apart from 2003 (dipping to 4%), CNS-related posters have remained steady at 11-17% throughout the decade. Respiratory-related posters have remained at 5-8% over the last 5years. Gastrointestinal (GI)-related posters have contributed 2-6% throughout the decade, and renal-related posters 1-3%. Posters on combined organ assessments have appeared in recent years. The relative emphasis on the different organ functions is broadly proportional to the causes of candidate drug attrition preclinically, whereas both CNS and GI are under-represented when considering their contribution to significant adverse effects during clinical development. Trends are either regulatory-driven (e.g. increase in posters on abuse-dependence liability since EMEA/CHMP/SWP/94227/2004), technology-driven (e.g. automated hERG assay; left ventricular function; non-invasive CVS measurements; stem cells, etc.), or relate to the predictive ability of safety pharmacology data (e.g. clinical translation initiatives; concordance between in vitro and in vivo preclinical data; integrated

Full Text Available This study investigated differences in health outcomes between active and passive school commuters, and examined associations between parent perceptions of the neighborhood environment and active school commuting (ASC. One hundred-ninety-four children (107 girls, aged 9–10 years from ten primary schools in Liverpool, England, participated in this cross-sectional study. Measures of stature, body mass, waist circumference and cardiorespiratory fitness (CRF were taken. School commute mode (active/passive was self-reported and parents completed the neighborhood environment walkability scale for youth. Fifty-three percent of children commuted to school actively. Schoolchildren who lived in more deprived neighborhoods perceived by parents as being highly connected, unaesthetic and having mixed land-use were more likely to commute to school actively (p < 0.05. These children were at greatest risk of being obese and aerobically unfit(p < 0.01. Our results suggest that deprivation may explain the counterintuitive relationship between obesity, CRF and ASC in Liverpool schoolchildren. These findings encourage researchers and policy makers to be equally mindful of the social determinants of health when advocating behavioral and environmental health interventions. Further research exploring contextual factors to ASC, and examining the concurrent effect of ASC and diet on weight status by deprivation is needed.

Friendship, curiosity and the city: Dementia friends and memory walks in Liverpool.

Phillips, Richard; Evans, Bethan

2018-02-01

The city is not just a context for friendships or a problem to be solved through them; it can be a catalyst for these relationships, sparking and strengthening connections between individuals and groups. Shared experiences of and curiosity in cities - expressed through practices that include revisiting familiar places and exploring others for the first time - can draw people together in beneficial ways. These principles underpin a health and wellbeing agenda, pioneered in Liverpool, which encourages people to 'take notice' and 'connect' - two of five 'ways to wellbeing' promoted through the Liverpool Decade of Health and Wellbeing. This paper focusses upon one particular set of schemes and relationships which brings all this into focus: befriending schemes designed to support people with dementia, which engage with objects and places as catalysts for connection. These observations shed a broader light upon the meanings and uses of friendship, with particular reference to cities.

The POLCOMS-WAM coupled wave and hydrodynamic model has been implemented at 1.8km resolution for the Irish Sea and 180m in a nested model of Liverpool Bay. It can be forced with output from the UK Met Office Unified Model. This allows the use of Smith and Banke (1975) and Charnock (1955) formulations for the wind-stress. The former gives an underestimate of the wind-stress, requiring enhanced winds for accurate surge hindcasts. While the latter gives good results for the Irish Sea and Liverpool Bay, with different values of the Charnock coefficient, it also allows the inclusion of a coupled wave stress into the wind-stress (Brown and Wolf, 2009). New results have been obtained by using wind and pressures from the WRF atmospheric model, allowing further development of air-sea coupling. The coupled model also includes bottom friction and the Doppler shift of the waves by the depth-averaged current), as well as advanced coupling procedures: use of the 3D current in the wave physics and calculation of radiation stress and Stokes' drift (Brown et al., 2011). During storm conditions it is found that the radiation stress is the most important term in this shallow water application. However, WAM runs in near real time, making this model only practical for research purposes. The model system has been used to hindcast tides, surges and waves in Liverpool Bay. Data are readily available from the Liverpool Bay Coastal Observatory to quantify the importance of each coupled term with the aim of producing the most accurate model setup for coastal forecasting. A storm event, 18th January 2007, has been hindcast to investigate extreme tide-surge-wave condition both offshore and inshore. During storm events, wave setup in shallow regions can contribute significantly to the total water elevation. The application of a 2D method to calculate radiation stress in a 3D hydrodynamic model is thoroughly examined by comparison with observations and a 3D model (Mellor, 2003). The results show

Creative potential: mental well-being impact assessment of the Liverpool 2008 European capital of culture programme.

Culture has a number of potential impacts upon health and well-being. This project was undertaken to assess the potential impacts of the Liverpool 2008 European Capital of Culture programme upon mental well-being, so that positive effects can be maximized and negative impacts reduced, in order that health and well-being are promoted and inequalities are reduced. A mental well-being impact assessment (MWIA) toolkit has been developed, and was piloted in this study. MWIA uses a sequence of procedures designed to systematically assess the effect of projects, programmes and policies upon people's mental well-being and health. The MWIA toolkit was used to explore the potential positive and negative impacts on mental well-being of a sample of projects and policies from the European Capital of Culture programme. This was achieved by asking stakeholders to answer a series of questions, holding participative workshops, constructing a community profile and reviewing the research literature. Recommendations were developed which aim to enhance the impact of the programme on people's mental well-being. As expected, both positive and negative impacts of the European Capital of Culture programme on mental well-being were identified. Fourteen themes were identified as emerging from the workshops, screening and reviewing the research evidence. Based on these data, 33 recommendations were developed by the project steering group and have been presented to the Liverpool Culture Company. The process of conducting the assessment, particularly its participatory nature and its awareness-raising role, had impacts upon mental well-being. The findings demonstrate the potential for the Culture Company programme to have a profound impact upon mental well-being, and highlight areas which could be addressed to optimize the impact of the programme. 2010 The Royal Society for Public Health.

Early GRB optical and infrared afterglow observations with the 2-m robotic Liverpool Telescope

International Nuclear Information System (INIS)

Gomboc, A.; Ljubljana Univ., Ljubljana; Mundell, C.G.; Guidorzi, C.

2005-01-01

We present the first optical observations of a Gamma Ray Burst IGRB) afterglow using the 2-m robotic Liverpool Telescope (LT), which is owned and operated by Liverpool John Moores University and situated on La Palma. We briefly discuss the capabilities of LT and its suitability for rapid follow-up observations of early optical and infrared GRB light curves. In particular, the combination of aperture, site, instrumentation and rapid response (robotic over-ride mode aided by telescope's rapid slew and fully-opening enclosure) makes the LT ideal for investigating the nature of short bursts, optically-dark bursts, and GRB blast-wave physics in general. We briefly describe the LT's key position in the RoboNet-1.0 network of robotic telescopes. We present the LT observations of GRB041006 and use its gamma-ray properties to predict the time of the break in optical light curve, a prediction consistent with the observations

Hospital is the most common place of cancer death but concerns regarding the quality of end-of-life care remain. Preliminary assessment of the effectiveness of the Liverpool Care Pathway on the quality of end-of-life care provided to adult cancer patients during their last week of life in hospital. Uncontrolled before-after intervention cluster trial. The trial was performed within four hospital wards participating in the pilot implementation of the Italian version of the Liverpool Care Pathway programme. All cancer patients who died in the hospital wards 2-4 months before and after the implementation of the Italian version of Liverpool Care Pathway were identified. A total of 2 months after the patient's death, bereaved family members were interviewed using the Toolkit After-Death Family Interview (seven 0-100 scales assessing the quality of end-of-life care) and the Italian version of the Views of Informal Carers - Evaluation of Services (VOICES) (three items assessing pain, breathlessness and nausea-vomiting). An interview was obtained for 79 family members, 46 (73.0%) before and 33 (68.8%) after implementation of the Italian version of Liverpool Care Pathway. Following Italian version of Liverpool Care Pathway implementation, there was a significant improvement in the mean scores of four Toolkit scales: respect, kindness and dignity (+16.8; 95% confidence interval = 3.6-30.0; p = 0.015); family emotional support (+20.9; 95% confidence interval = 9.6-32.3; p family self-efficacy (+14.3; 95% confidence interval = 0.3-28.2; p = 0.049) and coordination of care (+14.3; 95% confidence interval = 4.2-24.3; p = 0.007). No significant improvement in symptom' control was observed. These results provide the first robust data collected from family members of a preliminary clinically significant improvement, in some aspects, of quality of care after the implementation of the Italian version of Liverpool Care Pathway programme. The poor effect for symptom control suggests

Metadata only record A physically based catchment model (SWAT) was used for recharge estimation in the headwaters of the Liverpool Plains in NSW, Australia. The study used water balance modelling at the catchment scale to derive parameters for long-term recharge estimation. The derived parameters were further assessed at a subcatchment scale. Modelling results suggest that recharge occurs only in wet years, and is dominated by a few significant years or periods. The results were matched by...

Process Pharmacology: A Pharmacological Data Science Approach to Drug Development and Therapy.

Science.gov (United States)

Lötsch, Jörn; Ultsch, Alfred

2016-04-01

A novel functional-genomics based concept of pharmacology that uses artificial intelligence techniques for mining and knowledge discovery in "big data" providing comprehensive information about the drugs' targets and their functional genomics is proposed. In "process pharmacology", drugs are associated with biological processes. This puts the disease, regarded as alterations in the activity in one or several cellular processes, in the focus of drug therapy. In this setting, the molecular drug targets are merely intermediates. The identification of drugs for therapeutic or repurposing is based on similarities in the high-dimensional space of the biological processes that a drug influences. Applying this principle to data associated with lymphoblastic leukemia identified a short list of candidate drugs, including one that was recently proposed as novel rescue medication for lymphocytic leukemia. The pharmacological data science approach provides successful selections of drug candidates within development and repurposing tasks. © 2016 The Authors CPT: Pharmacometrics & Systems Pharmacology published by Wiley Periodicals, Inc. on behalf of American Society for Clinical Pharmacology and Therapeutics.

A Health Economics Response to the Review of the Liverpool Care Pathway

Science.gov (United States)

Coast, Joanna

2013-01-01

Abstract Background: In 2011 the Palliative Care Funding Review highlighted concerns about the funding, provision, and quality of care at the end of life. Two years on, an independent review of the Liverpool Care Pathway—prompted by a storm of negative media coverage— has raised concerns around a lack of funding, availability of support for the dying and their relatives, and patient centered care. There are recommendations to increase funding through a national tariff for palliative care services, address inconsistencies, and replace the Liverpool Care Pathway with individual end-of-life care plans. Objective: This paper explores the economic implications of the review's recommendations and links these to inadequacies with the current economic framework currently recommended for use in the United Kingdom by the National Institute for Health and Care Excellence, before highlighting aspects of ongoing research aimed at addressing these inadequacies. Methods: As well as the published report More Care, Less Pathway, we draw upon preliminary qualitative evidence from 19 semistructured interviews conducted with academics specializing in economics and/or end-of-life care. Conclusions: While there is a need for increased funding in the short term (highlighted in recent reviews), increasing funding to services that have little evidence base appears to be an irresponsible long-term strategy. Hence there should also be increased investment in research and increased emphasis in particular on developing economic tools to evaluate services. PMID:24199790

More than 50 Norwegian public and private laboratories provide one or more analyses for therapeutic drug monitoring or testing for drugs of abuse. Practices differ among laboratories, and analytical repertoires can change rapidly as new substances become available for analysis. The Pharmacology Portal was developed to provide an overview of these activities and to standardize the practices and terminology among laboratories. The Pharmacology Portal is a modern dynamic web database comprising all available analyses within therapeutic drug monitoring and testing for drugs of abuse in Norway. Content can be retrieved by using the search engine or by scrolling through substance lists. The core content is a substance registry updated by a national editorial board of experts within the field of clinical pharmacology. This ensures quality and consistency regarding substance terminologies and classification. All laboratories publish their own repertoires in a user-friendly workflow, adding laboratory-specific details to the core information in the substance registry. The user management system ensures that laboratories are restricted from editing content in the database core or in repertoires within other laboratory subpages. The portal is for nonprofit use, and has been fully funded by the Norwegian Medical Association, the Norwegian Society of Clinical Pharmacology, and the 8 largest pharmacologic institutions in Norway. The database server runs an open-source content management system that ensures flexibility with respect to further development projects, including the potential expansion of the Pharmacology Portal to other countries.

Full Text Available Bipolar disorder is an important psychiatric disorder with different disease phases. The pharmacological treatment is complicated, and is updated frequently as new research evidence emerges. For the purpose of international collaboration, research, and education, the Taiwan consensus of pharmacological treatment for bipolar disorders was initiated by the Taiwanese Society of Biological Psychiatry and Neuropsychopharmacology (TSBPN – the Bipolar Chapter, which was established in August 2010 and approved as a member of International Society of Bipolar Disorder. TSBPN is the country member of the World Federation of Societies of Biological Psychiatry (WFSBP. The development of the Taiwan consensus for bipolar disorder was mainly based on the template of WFSBP Guidelines, with references to other international guidelines including the Canadian Network for Mood and Anxiety Treatments, and British Association for Psychopharmacology. We have also added Taiwanese experts’ experience, Taiwan national health insurance data, and the indications for the pharmacological treatment of bipolar disorder given by the Taiwan Department of Health, to emphasize the balance between efficacy and safety, and to make this consensus a concise, empirical, and important reference for clinical psychiatric practice.

Social Media Strategy in Professional Football: The case of Liverpool FC

Petros Parganas

2015-10-01

Full Text Available The purpose of this study is to examine the role of social media as marketing tools in professional team sport organizations. Focusing on the English Premier League football club Liverpool FC, an exploratory case study design using one-to-one inter- views with the club’s senior social media managers was adopt- ed. The findings highlight the need for integration of all media channels of the club in order to allow for a more targeted and engaging approach towards its fans, and suggests that further development of social media strategies has potential to deliver increased commercial gains both in the short and in the long term. However, given the peculiar nature of sports fandom, a major issue for social media managers is to find the appropriate balance between content that increases fan interaction and engagement and content that deals with purely commercial purposes.

Perinatal pharmacology: applications for neonatal neurology.

Smits, Anne; Allegaert, Karel

2011-11-01

The principles of clinical pharmacology also apply to neonates, but their characteristics warrant a tailored approach. We focus on aspects of both developmental pharmacokinetics (concentration/time relationship) and developmental pharmacodynamics (concentration/effect relationship) in neonates. We hereby aimed to link concepts used in clinical pharmacology with compound-specific observations (anti-epileptics, analgosedatives) in the field of neonatal neurology. Although in part anecdotal, we subsequently illustrate the relevance of developmental pharmacology in the field of neonatal neurology by a specific intervention (e.g. whole body cooling), specific clinical presentations (e.g. short and long term outcome following fetal exposure to antidepressive agents, the development of new biomarkers for fetal alcohol syndrome) and specific clinical needs (e.g. analgosedation in neonates, excitocytosis versus neuro-apoptosis/impaired synaptogenesis).

Experimental study of the cline of industrial melanism in Biston betularia (L. ) (Lepidoptera) between urban Liverpool and rural North Wales

Energy Technology Data Exchange (ETDEWEB)

Bishop, J A

1972-01-01

Some populations of moths are polymorphic, containing industrial melanic and nonmelanic forms. The melanics are camouflaged from bird predators in grimy, smoke polluted areas and non-melanics are conspicuous. The reverse situation occurs in unpolluted countryside. A mark-release-recapture experiment estimated parameters of the population of male moths in a circular area of 5 km radius. Marked moths, released in a wood at the center of the area flew up to 5.8 km a night. The 24-hour survival rates of the carbonaria melanic and typical females wre estimated at seven places along a cline. The survival rates for carbonaria females decline with distance from Liverpool while those for the typical form increase. The survival rates were used to calculate selective coefficients. The regression of selective coefficient against distance from central Liverpool was significant. A computer model was used in an attempt to resynthesize the original cline from the experimental data. The selective coefficients measured did not produce a good fit in the more rural parts of the cline; this suggests that the melanic form has some hitherto unsuspected advantage in rural areas which more than counterbalances its visual disadvantages. 48 references, 11 figures, 16 tables.

The biological pigment melanin is present in most of the biological systems. It manifests a host of biological and pharmacological properties. Its role as a molecule with special properties and functions affecting general health, including photoprotective and immunological action, are well recognized. Its antioxidant, anti-inflammatory, immunomodulatory, radioprotective, hepatic, gastrointestinal and hypoglycaemic benefits have only recently been recognized and studied. It is also associated with certain disorders of the nervous system. In this MiniReview, we consider the steadily increasing literature on the bioavailability and functional activity of melanin. Published literature shows that melanin may play a number of possible pharmacological effects such as protective, stimulatory, diagnostic and curative roles in human health. In this MiniReview, possible health roles and pharmacological effects are considered. © 2016 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

2005-01-01

Purpose To report on outcomes after proton beam radiotherapy of choroidal melanoma using a 62-MeV cyclotron in patients considered unsuitable for other forms of conservative therapy. Methods and Materials A total of 349 patients with choroidal melanoma referred to the Liverpool Ocular Oncology Centre underwent proton beam radiotherapy at Clatterbridge Centre for Oncology (CCO) between January 1993 and December 2003. Four daily fractions of proton beam radiotherapy were delivered, with a total dose of 53.1 proton Gy, and with lateral and distal safety margins of 2.5 mm. Outcomes measured were local tumor recurrence; ocular conservation; vision; and metastatic death according to age, gender, eye, visual acuity, location of anterior and posterior tumor margins, quadrant, longest basal tumor dimension, tumor height, extraocular extension, and retinal invasion. Results The 5-year actuarial rates were 3.5% for local tumor recurrence, 9.4% for enucleation, 79.1% for conservation of vision of counting fingers or better, 61.1% for conservation of vision of 20/200 or better, 44.8% for conservation of vision of 20/40 or better, and 10.0% for death from metastasis. Conclusion Proton beam radiotherapy with a 62 MeV cyclotron achieves high rates of local tumor control and ocular conservation, with visual outcome depending on tumor size and location

Full Text Available This arcticle aims to analyze the relation between sounds and images in Lisandro Alonso’s Los Muertos and Liverpool. It is of our interest to think about the narrative roles given to sound effects and ambient sounds, to speak of the importance given to such sound elements, opposite to the minor role played by music and dialogue, all that working within the cinematic regime of the sequence shot. Therefore, this work tries, most of all, to investigate how ambient sounds and diegetic noises contribute for such a particular temporal construction. It is also a secundary goal to establish some relationship between those films and other examples of a cinema that has declined the usual dialogue’s central narrative part, as well as to recall the ideia and definition of a cinema of poetry.

Clinical pharmacology in Russia has long history and is currently active, but rather unrecognized internationally. It is governmentally approved as a teaching/scientific specialty since 1983 and as a medical specialty since 1997. Courses of clinical pharmacology are included in the undergraduate curricula in the 5th and/or 6th year of education at all medical schools in the Russian Federation. Postgraduate education includes initial specialization in internal medicine with further residency in clinical pharmacology. Governmental legislation recommends that every healthcare institution has either a department or a single position of clinical pharmacologist. Major routine duties include information about and monitoring of medication use, consultations in difficult clinical situations, pharmacogenetic counseling, therapeutic drug monitoring, pharmacovigilance, and participation in drug and therapeutics (formulary) committees. There are official experts in clinical pharmacology in Russia responsible for coordinating relevant legislative issues. The chief expert clinical pharmacologist represents the discipline directly at the Ministry of Health. Research in clinical pharmacology in Russia is extensive and variable, but only some of it is published internationally. Russia is a participant of international societies of clinical pharmacology and therapeutics and collaboration is actively ongoing. There are still certain problems related to the development of the discipline in Russia-some healthcare institutions do not see the need for clinical pharmacology. However, the number of clinical pharmacologists in Russia is increasing as well as their role in physicians' education, national healthcare, and research.

Full Text Available Event legacy has become a major topic of discussion in recent years. Especially, European Capital of Culture is emerging as a means of facilitating community development in Europe. Based on a case study of the 2008 European Capital of Culture Liverpool, this article aims to conceptualise the relationship between an event and its sustained effects on community development. Methodologically, adopting case study as approach, both primary and secondary were collected and analysed, including four times neighborhood surveys, official evaluation reports and academic publications. The study period is from 2007 to 2015 to monitor changes in an event’s impacts. The results reveal four dimensions of effects, including: cultural access and engagement, volunteering, governance and infrastructure, and sense of place. Overall, the study stresses the importance of integrating the event into a long-term development strategy of the city, through synergies between culture and urban regeneration and community renewal.

Abstract Objective To provide family physicians with a practical clinical summary of the Canadian Pain Society (CPS) revised consensus statement on the pharmacologic management of neuropathic pain. Quality of evidence A multidisciplinary interest group within the CPS conducted a systematic review of the literature on the current treatments of neuropathic pain in drafting the revised consensus statement. Main message Gabapentinoids, tricyclic antidepressants, and serotonin-norepinephrine reuptake inhibitors are the first-line agents for treating neuropathic pain. Tramadol and other opioids are recommended as second-line agents, while cannabinoids are newly recommended as third-line agents. Other anticonvulsants, methadone, tapentadol, topical lidocaine, and botulinum toxin are recommended as fourth-line agents. Conclusion Many pharmacologic analgesics exist for the treatment of neuropathic pain. Through evidence-based recommendations, the CPS revised consensus statement helps guide family physicians in the management of patients with neuropathic pain. PMID:29138154

In this paper we discuss the consensus view on the use of qualifying biomarkers in drug safety, raised within the frame of the XXIV meeting of the Spanish Society of Clinical Pharmacology held in Málaga (Spain) in October, 2011. The widespread use of biomarkers as surrogate endpoints is a goal that scientists have long been pursuing. Thirty years ago, when molecular pharmacogenomics evolved, we anticipated that these genetic biomarkers would soon obviate the routine use of drug therapies in a way that patients should adapt to the therapy rather than the opposite. This expected revolution in routine clinical practice never took place as quickly nor with the intensity as initially expected. The concerted action of operating multicenter networks holds great promise for future studies to identify biomarkers related to drug toxicity and to provide better insight into the underlying pathogenesis. Today some pharmacogenomic advances are already widely accepted, but pharmacogenomics still needs further development to elaborate more precise algorithms and many barriers to implementing individualized medicine exist. We briefly discuss our view about these barriers and we provide suggestions and areas of focus to advance in the field.

Human pharmacology for addiction medicine: From evidence to clinical recommendations.

Quednow, Boris B; Herdener, Marcus

2016-01-01

Substance use disorders (SUD) are complex and often chronic diseases with negative health outcomes and social consequences. Pharmacological treatment options for SUD can be separated in medications for (i) intoxication, (ii) withdrawal, and (iii) reduction of use together with relapse prevention. This chapter will focus on approved or clinically established pharmacological strategies suited to manage symptoms of withdrawal, and to reduce substance use or to promote abstinence. Hereby SUD involving alcohol, nicotine, stimulants, and opioids are primarily discussed as these substances are considered most harmful for both the individual and the society. Moreover, the pharmacotherapy of SUD related to the use of cannabis, benzodiazepines, and gamma-hydroxybutyrate is also briefly reviewed. Since most approved pharmacological treatment options show only moderate effect sizes especially in the long term, the development of new treatment strategies including new drugs, new combinations of available compounds, and biomarkers for response prediction is still warranted. © 2016 Elsevier B.V.

Arduino, Daniela M; Perocchi, Fabiana

2018-01-10

Mitochondria are pivotal organelles in calcium (Ca 2+ ) handling and signalling, constituting intracellular checkpoints for numerous processes that are vital for cell life. Alterations in mitochondrial Ca 2+ homeostasis have been linked to a variety of pathological conditions and are critical in the aetiology of several human diseases. Efforts have been taken to harness mitochondrial Ca 2+ transport mechanisms for therapeutic intervention, but pharmacological compounds that direct and selectively modulate mitochondrial Ca 2+ homeostasis are currently lacking. New avenues have, however, emerged with the breakthrough discoveries on the genetic identification of the main players involved in mitochondrial Ca 2+ influx and efflux pathways and with recent hints towards a deep understanding of the function of these molecular systems. Here, we review the current advances in the understanding of the mechanisms and regulation of mitochondrial Ca 2+ homeostasis and its contribution to physiology and human disease. We also introduce and comment on the recent progress towards a systems-level pharmacological targeting of mitochondrial Ca 2+ homeostasis. © 2018 The Authors.

Guidance regarding the patient centred management of agitation and restlessness reinforces the importance of considering underlying causes, non-pharmacological approaches to treatment and judicious use of medications titrated to patient need. In contrast, recent reports in the literature suggest that the practice of continuous deep sedation until death is prevalent in the UK. To use data from the National Care of the Dying Audit-Hospitals (NCDAH) to explore the administration of medication for management of agitation and restlessness in the last 24 h of life. Hospitals submitted data from up to 30 consecutive adult patients whose care in the final hours/days of life was supported by the Liverpool Care Pathway for the Dying Patient (LCP). Data on the total dose received in the last 24 h of life PRN and the last dose prescribed for administration via continuous subcutaneous infusion (CSCI) for agitation and restlessness were submitted. 155 hospitals provided data from 3893 patients. Median total doses in the last 24 h for midazolam, haloperidol and levomepromazine, respectively, were: PRN only, 2.5, 1.5 and 6.25 mg; CSCI only, 10, 3 and 6.25 mg; PRN+CSCI, 15, 3 and 12.5 mg. Only 51% of patients received medication to alleviate agitation and restlessness in the last 24 h of life. Median doses were low in comparison to doses recommended for continuous deep sedation, suggesting that there is no 'blanket' policy for continuous deep sedation at the end of life for patients whose care is supported by the LCP.

Education and non-pharmacological approaches for gout.

Abhishek, Abhishek; Doherty, Michael

2018-01-01

The objectives of this review are as follows: to highlight the gaps in patient and physician knowledge of gout and how this might impede optimal disease management; to provide recommended core knowledge points that should be conveyed to people with gout; and to review non-pharmacological interventions that can be used in gout management. MeSH terms were used to identify eligible studies examining patients' and health-care professionals' knowledge about gout and its management. A narrative review of non-pharmacological management of gout is provided. Many health-care professionals have significant gaps in their knowledge about gout that have the potential to impede optimal management. Likewise, people with gout and the general population lack knowledge about causes, consequences and treatment of this condition. Full explanation about gout, including the potential benefits of urate-lowering treatment (ULT), motivates people with gout to want to start such treatment, and there is evidence, albeit limited, that educational interventions can improve uptake and adherence to ULT. Additionally, several non-pharmacological approaches, such as rest and topical ice application for acute attacks, avoidance of risk factors that can trigger acute attacks, and dietary interventions that may reduce gout attack frequency (e.g. cherry or cherry juice extract, skimmed milk powder or omega-3 fatty acid intake) or lower serum uric acid (e.g. vitamin C), can be used as adjuncts to ULT. There is a pressing need to educate health-care professionals, people with gout and society at large to remove the negative stereotypes associated with gout, which serve as barriers to optimal gout management, and to perceive gout as a significant medical condition. Moreover, there is a paucity of high-quality trial evidence on whether certain simple individual dietary and lifestyle factors can reduce the risk of recurrent gout attacks, and further studies are required in this field. © The Author 2018

Objectives (1) To investigate differences in health-related, home and neighbourhood environmental variables between Liverpool children living in areas of high deprivation (HD) and medium-to-high deprivation (MD) and (2) to assess associations between these perceived home and neighbourhood environments and health-related variables stratified by deprivation group. Design Cross-sectional study. Setting 10 Liverpool primary schools in 2014. Participants 194 children aged 9–10 years. Main outcome measures Health-related variables (self-reported physical activity (PA) (Physical Activity Questionnaire for Older Children, PAQ-C), cardiorespiratory fitness, body mass index (BMI) z-scores, waist circumference), home environment variables: (garden/backyard access, independent mobility, screen-based media restrictions, bedroom media) and neighbourhood walkability (Neighbourhood Environment Walkability Scale for Youth, NEWS-Y). Explanatory measures Area deprivation. Results There were significant differences between HD and MD children's BMI z-scores (p<0.01), waist circumference (p<0.001) and cardiorespiratory fitness (p<0.01). HD children had significantly higher bedroom media availability (p<0.05) and independent mobility scores than MD children (p<0.05). MD children had significantly higher residential density and neighbourhood aesthetics scores, and lower crime safety, pedestrian and road traffic safety scores than HD children, all of which indicated higher walkability (p<0.01). HD children's BMI z-scores (β=−0.29, p<0.01) and waist circumferences (β=−0.27, p<0.01) were inversely associated with neighbourhood aesthetics. HD children's PA was negatively associated with bedroom media (β=−0.24, p<0.01), and MD children's PA was positively associated with independent mobility (β=0.25, p<0.01). MD children's independent mobility was inversely associated with crime safety (β=−0.28, p<0.01) and neighbourhood aesthetics (β=−0.24, p<0.05). Conclusions Children

Pharmacotherapy might be improved if future pharmacists and physicians receive a joint educational programme in pharmacology and pharmacotherapeutics. This study investigated whether there are differences in the pharmacology and pharmacotherapy knowledge and skills of pharmacy and medical students after their undergraduate training. Differences could serve as a starting point from which to develop joint interdisciplinary educational programmes for better prescribing. In a cross-sectional design, the knowledge and skills of advanced pharmacy and medical students were assessed, using a standardized test with three domains (basic pharmacology knowledge, clinical or applied pharmacology knowledge and pharmacotherapy skills) and eight subdomains (pharmacodynamics, pharmacokinetics, interactions and side-effects, Anatomical Therapeutic Chemical Classification groups, prescribing, prescribing for special groups, drug information, regulations and laws, prescription writing). Four hundred and fifty-one medical and 151 pharmacy students were included between August 2010 and July 2012. The response rate was 81%. Pharmacy students had better knowledge of basic pharmacology than medical students (77.0% vs. 68.2% correct answers; P students had better skills than pharmacy students in writing prescriptions (68.6% vs. 50.7%; P students had similar knowledge of applied pharmacology (73.8% vs. 72.2%, P = 0.124, δ = 0.15). Pharmacy students have better knowledge of basic pharmacology, but not of the application of pharmacology knowledge, than medical students, whereas medical students are better at writing prescriptions. Professional differences in knowledge and skills therefore might well stem from their undergraduate education. Knowledge of these differences could be harnessed to develop a joint interdisciplinary education for both students and professionals. © 2014 The British Pharmacological Society.

2011-10-01

To explore nutrition and food provision in pre-school nurseries in order to develop interventions to promote healthy eating in pre-school settings. Quantitative data were gathered using questionnaires and professional menu analysis. In the community, at pre-school nurseries. All 130 nurseries across Liverpool were a sent questionnaire (38 % response rate); thirty-four menus were returned for analysis (26 % response rate). Only 21 % of respondents stated they had adequate knowledge on nutrition for pre-school children. Sixty-one per cent of cooks reported having received only a 'little' advice on healthy eating and this was often not specific to under-5 s nutrition. Fifty-seven per cent of nurseries did not regularly assess their menus for nutritional quality. The menu analysis revealed that all menus were deficient in energy, carbohydrate, Fe and Zn. Eighty-five per cent of nurseries had Na/salt levels which exceed guidelines. Nurseries require support on healthy eating at policy, knowledge and training levels. This support should address concerns relating to both menu planning and ingredients used in food provision and meet current guidelines on food provision for the under-5 s.

Delirium in the elderly: A systematic review of pharmacological and non-pharmacological treatments

Directory of Open Access Journals (Sweden)

Cecília Carboni Tardelli Cerveira

Full Text Available ABSTRACT Delirium is a common disorder associated with poor prognosis, especially in the elderly. The impact of different treatment approaches for delirium on morbimortality and long-term welfare is not completely understood. OBJECTIVE: To determine the efficacy of pharmacological and non-pharmacological treatments in elderly patients with delirium. METHODS: This systematic review compared pharmacological and non-pharmacological treatments in patients over 60 years old with delirium. Databases used were: MEDLINE (PubMed, EMBASE, Cochrane CENTRAL and LILACS from inception to January 6th, 2016. RESULTS: A total of ten articles were selected. The six non-pharmacological intervention studies showed no impact on duration of delirium, mortality or institutionalization, but a decrease in severity of delirium and improvement in medium-term cognitive function were observed. The most commonly used interventions were temporal-spatial orientation, orientation to self and others, early mobilization and sleep hygiene. The four studies with pharmacological interventions found that rivastigmine reduced the duration of delirium, improved cognitive function and reduced caregiver burden; olanzapine and haloperidol decreased the severity of delirium; droperidol reduced length of hospitalization and improved delirium remission rate. CONCLUSION: Although the pharmacological approach has been used in the treatment of delirium among elderly, there have been few studies assessing its efficacy, involving a small number of patients. However, the improvements in delirium duration and severity suggest these drugs are effective in treating the condition. Once delirium has developed, non-pharmacological treatment seems less effective in controlling symptoms, and there is a lack of studies describing different non-pharmacological interventions.

2010 Canadian Cardiovascular Society/Canadian Heart Rhythm Society Training Standards and Maintenance of Competency in Adult Clinical Cardiac Electrophysiology.

Green, Martin S; Guerra, Peter G; Krahn, Andrew D

2011-01-01

The last guidelines on training for adult cardiac electrophysiology (EP) were published by the Canadian Cardiovascular Society in 1996. Since then, substantial changes in the knowledge and practice of EP have mandated a review of the previous guidelines by the Canadian Heart Rhythm Society, an affiliate of the Canadian Cardiovascular Society. Novel tools and techniques also now allow electrophysiologists to map and ablate increasingly complex arrhythmias previously managed with pharmacologic or device therapy. Furthermore, no formal attempt had previously been made to standardize EP training across the country. The 2010 Canadian Cardiovascular Society/Canadian Heart Rhythm Society Training Standards and Maintenance of Competency in Adult Clinical Cardiac Electrophysiology represent a consensus arrived at by panel members from both societies, as well as EP program directors across Canada and other select contributors. In describing program requirements, the technical and cognitive skills that must be acquired to meet training standards, as well as the minimum number of procedures needed in order to acquire these skills, the new guidelines provide EP program directors and committee members with a template to develop an appropriate curriculum for EP training for cardiology fellows here in Canada.

Private finance initiative hospital architecture: towards a political economy of the Royal Liverpool University Hospital.

Science.gov (United States)

Jones, Paul

2018-02-01

Sociological analysis has done much to illuminate the architectural contexts in which social life takes place. Research on care environments suggests that the built environment should not be understood as a passive backdrop to healthcare, but rather that care is conditioned by the architecture in which it happens. This article argues for the importance of going beyond the hospital walls to include the politics that underwrite the design and construction of hospital buildings. The article assesses the case of the yet-to-be-realised Liverpool Royal University Hospital, and the private finance initiative (PFI) funding that underpins the scheme, which is suggested as a salient 'external' context for understanding architecture's role in the provision of healthcare of many kinds for many years to come. PFI has major implications for democratic accountability and local economy, as well as for the architecture of the hospital as a site of care. Critical studies can illuminate these paradoxically visible-but-opaque hospital spaces by going beyond that which is immediately empirically evident, so as to reveal the ways in which hospital architecture is conditioned by political and economic forces. © 2018 Foundation for the Sociology of Health & Illness.

The Small Telescopes Installed at the Liverpool Telescope (STILT) project has been in operation since March 2009, collecting data with three wide field unfiltered cameras: SkycamA, SkycamT and SkycamZ. To process the data, a pipeline was developed to automate source extraction, catalogue cross-matching, photometric calibration and database storage. In this paper, modifications and further developments to this pipeline will be discussed, including a complete refactor of the pipeline's codebase into Python, migration of the back-end database technology from MySQL to PostgreSQL, and changing the catalogue used for source cross-matching from USNO-B1 to APASS. In addition to this, details will be given relating to the development of a preliminary front-end to the source extracted database which will allow a user to perform common queries such as cone searches and light curve comparisons of catalogue and non-catalogue matched objects. Some next steps and future ideas for the project will also be presented.

The Liverpool Elbow Score (LES) is a newly developed, validated elbow-specific score. It consists of a patient-answered questionnaire (PAQ) and a clinical assessment. The purpose of this study was to determine whether the PAQ portion of the LES could be used independently as a postal questionnaire for the assessment of outcome after total elbow arthroplasty and to correlate the LES and the Mayo Elbow Performance Score (MEPS). A series of 51 total elbow replacements were reviewed by postal questionnaire. Patients then attended the clinic for assessment by use of both the LES and the MEPS. There was an excellent response rate to the postal questionnaire (98%), and 44 elbows were available for clinical review. Good correlation was shown between the LES and the MEPS (Spearman correlation coefficient, 0.84; P PAQ portion of the LES and the MEPS (Spearman correlation coefficient, 0.76; P PAQ component and the MEPS, suggesting that outcome assessment is possible by postal questionnaire.

Pharmacological Management of Chronic Neuropathic Pain – Consensus Statement and Guidelines from the Canadian Pain Society

Directory of Open Access Journals (Sweden)

DE Moulin

2007-01-01

Full Text Available Neuropathic pain (NeP, generated by disorders of the peripheral and central nervous system, can be particularly severe and disabling. Prevalence estimates indicate that 2% to 3% of the population in the developed world suffer from NeP, which suggests that up to one million Canadians have this disabling condition. Evidence-based guidelines for the pharmacological management of NeP are therefore urgently needed. Randomized, controlled trials, systematic reviews and existing guidelines focusing on the pharmacological management of NeP were evaluated at a consensus meeting. Medications are recommended in the guidelines if their analgesic efficacy was supported by at least one methodologically sound, randomized, controlled trial showing significant benefit relative to placebo or another relevant control group. Recommendations for treatment are based on degree of evidence of analgesic efficacy, safety, ease of use and cost-effectiveness. Analgesic agents recommended for first-line treatments are certain antidepressants (tricyclics and anticonvulsants (gabapentin and pregabalin. Second-line treatments recommended are serotonin noradrenaline reuptake inhibitors and topical lidocaine. Tramadol and controlled-release opioid analgesics are recommended as third-line treatments for moderate to severe pain. Recommended fourth-line treatments include cannabinoids, methadone and anticonvulsants with lesser evidence of efficacy, such as lamotrigine, topiramate and valproic acid. Treatment must be individualized for each patient based on efficacy, side-effect profile and drug accessibility, including cost. Further studies are required to examine head-to-head comparisons among analgesics, combinations of analgesics, long-term outcomes, and treatment of pediatric and central NeP.

Some additional JABA publications have included investigations of the behavioral effects of other drugs. However, a review of these articles revealed many methodological differences among studies, which makes it difficult to evaluate the relative contribution of each research effort to the overall database. In this context, we offer some guidelines to solidify the methodological rigor of behavior pharmacological research published in JABA. © Society for the Experimental Analysis of Behavior.

Carotenoids: biochemistry, pharmacology and treatment.

Carotenoids and retinoids have several similar biological activities such as antioxidant properties, the inhibition of malignant tumour growth and the induction of apoptosis. Supplementation with carotenoids can affect cell growth and modulate gene expression and immune responses. Epidemiological studies have shown a correlation between a high carotenoid intake in the diet with a reduced risk of breast, cervical, ovarian, colorectal cancers, and cardiovascular and eye diseases. Cancer chemoprevention by dietary carotenoids involves several mechanisms, including effects on gap junctional intercellular communication, growth factor signalling, cell cycle progression, differentiation-related proteins, retinoid-like receptors, antioxidant response element, nuclear receptors, AP-1 transcriptional complex, the Wnt/β-catenin pathway and inflammatory cytokines. Moreover, carotenoids can stimulate the proliferation of B- and T-lymphocytes, the activity of macrophages and cytotoxic T-cells, effector T-cell function and the production of cytokines. Recently, the beneficial effects of carotenoid-rich vegetables and fruits in health and in decreasing the risk of certain diseases has been attributed to the major carotenoids, β-carotene, lycopene, lutein, zeaxanthin, crocin (/crocetin) and curcumin, due to their antioxidant effects. It is thought that carotenoids act in a time- and dose-dependent manner. In this review, we briefly describe the biological and immunological activities of the main carotenoids used for the treatment of various diseases and their possible mechanisms of action.

Pharmacologic modulation of protein kinase C isozymes: the role of RACKs and subcellular localisation.

Science.gov (United States)

Csukai, M; Mochly-Rosen, D

1999-04-01

Protein kinase C (PKC) isozymes are highly homologous kinases and several different isozymes can be present in a cell. Each isozyme is likely to mediate unique functions, but pharmacological tools to explore their isozyme-specific roles have not been available until recently. In this review, we describe the development and application of isozyme-selective inhibitors of PKC. The identification of these inhibitors stems from the observation that PKC isozymes are each localised to unique subcellular locations following activation. Inhibitors of this isozyme-unique localisation have been shown to act as selective inhibitors of the functions of individual isozymes. The identification of isozyme-specific inhibitors should allow the exploration of individual PKC isozyme function in a wide range of cell systems. Copyright 1999 The Italian Pharmacological Society.

Quantitative Systems Pharmacology (QSP) is experiencing increased application in the drug discovery and development process. Like its older sibling, systems biology, the QSP field is comprised of a mix of established disciplines and methods, from molecular biology to engineering to pharmacometrics. As a result, there exist critical segments of the discipline that differ dramatically in approach and a need to bring these groups together toward a common goal. © 2016 The Authors CPT: Pharmacometrics & Systems Pharmacology published by Wiley Periodicals, Inc. on behalf of American Society for Clinical Pharmacology and Therapeutics.

Fuzzy pharmacology: theory and applications.

Science.gov (United States)

Sproule, Beth A; Naranjo, Claudio A; Türksen, I Burhan

2002-09-01

Fuzzy pharmacology is a term coined to represent the application of fuzzy logic and fuzzy set theory to pharmacological problems. Fuzzy logic is the science of reasoning, thinking and inference that recognizes and uses the real world phenomenon that everything is a matter of degree. It is an extension of binary logic that is able to deal with complex systems because it does not require crisp definitions and distinctions for the system components. In pharmacology, fuzzy modeling has been used for the mechanical control of drug delivery in surgical settings, and work has begun evaluating its use in other pharmacokinetic and pharmacodynamic applications. Fuzzy pharmacology is an emerging field that, based on these initial explorations, warrants further investigation.

2016-01-01

Chronic pain occurs in as many as 85% of individuals with HIV and is associated with substantial functional impairment. Little guidance is available for HIV providers seeking to address their patients’ chronic pain. We conducted a systematic review to identify clinical trials and observational studies that examined the impact of pharmacologic or non-pharmacologic interventions on pain and/or functional outcomes among HIV-infected individuals with chronic pain in high-development countries. Eleven studies met inclusion criteria and were mostly low or very low quality. Seven examined pharmacologic interventions (gabapentin, pregabalin, capsaicin, analgesics including opioids) and four examined non-pharmacologic interventions (cognitive behavioral therapy, self-hypnosis, smoked cannabis). The only controlled studies with positive results were of capsaicin and cannabis, and had short-term follow-up (≤12 weeks). Among the seven studies of pharmacologic interventions, five had substantial pharmaceutical industry sponsorship. These findings highlight several important gaps in the HIV/chronic pain literature that require further research. PMID:27267445

2013-07-01

Regenerative medicine is a rapidly evolving multidisciplinary, translational research enterprise whose explicit purpose is to advance technologies for the repair and replacement of damaged cells, tissues, and organs. Scientific progress in the field has been steady and expectations for its robust clinical application continue to rise. The major thesis of this review is that the pharmacological sciences will contribute critically to the accelerated translational progress and clinical utility of regenerative medicine technologies. In 2007, we coined the phrase "regenerative pharmacology" to describe the enormous possibilities that could occur at the interface between pharmacology, regenerative medicine, and tissue engineering. The operational definition of regenerative pharmacology is "the application of pharmacological sciences to accelerate, optimize, and characterize (either in vitro or in vivo) the development, maturation, and function of bioengineered and regenerating tissues." As such, regenerative pharmacology seeks to cure disease through restoration of tissue/organ function. This strategy is distinct from standard pharmacotherapy, which is often limited to the amelioration of symptoms. Our goal here is to get pharmacologists more involved in this field of research by exposing them to the tools, opportunities, challenges, and interdisciplinary expertise that will be required to ensure awareness and galvanize involvement. To this end, we illustrate ways in which the pharmacological sciences can drive future innovations in regenerative medicine and tissue engineering and thus help to revolutionize the discovery of curative therapeutics. Hopefully, the broad foundational knowledge provided herein will spark sustained conversations among experts in diverse fields of scientific research to the benefit of all.

To gather expert opinion on the conduct of clinical trials that will facilitate regulatory review and approval of appropriate efficacious pharmacological treatments for hand osteoarthritis (OA), an area of high unmet clinical need. The European Society on Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal diseases (ESCEO) organized a working group under the auspices of the International Osteoporosis Foundation (IOF) and the World Health Organization (WHO). This consensus guideline is intended to provide a reference tool for practice, and should allow for better standardization of the conduct of clinical trials in hand OA. Hand OA is a heterogeneous disease affecting different, and often multiple, joints of the thumb and fingers. It was recognized that the various phenotypes and limitations of diagnostic criteria may make the results of hand OA trials difficult to interpret. Nonetheless, practical recommendations for the conduct of clinical trials of both symptom and structure modifying drugs are outlined in this consensus statement, including guidance on study design, execution, and analysis. While the working group acknowledges that the methodology for performing clinical trials in hand OA will evolve as knowledge of the disease increases, it is hoped that this guidance will support the development of new pharmacological treatments targeting hand OA.

The preclinical pharmacology of mephedrone; not just MDMA by another name.

Science.gov (United States)

Green, A R; King, M V; Shortall, S E; Fone, K C F

2014-05-01

The substituted β-keto amphetamine mephedrone (4-methylmethcathinone) was banned in the UK in April 2010 but continues to be used recreationally in the UK and elsewhere. Users have compared its psychoactive effects to those of 3,4-methylenedioxymethamphetamine (MDMA, 'ecstasy'). This review critically examines the preclinical data on mephedrone that have appeared over the last 2-3 years and, where relevant, compares the pharmacological effects of mephedrone in experimental animals with those obtained following MDMA administration. Both mephedrone and MDMA enhance locomotor activity and change rectal temperature in rodents. However, both of these responses are of short duration following mephedrone compared with MDMA probably because mephedrone has a short plasma half-life and rapid metabolism. Mephedrone appears to have no pharmacologically active metabolites, unlike MDMA. There is also little evidence that mephedrone induces a neurotoxic decrease in monoamine concentration in rat or mouse brain, again in contrast to MDMA. Mephedrone and MDMA both induce release of dopamine and 5-HT in the brain as shown by in vivo and in vitro studies. The effect on 5-HT release in vivo is more marked with mephedrone even though both drugs have similar affinity for the dopamine and 5-HT transporters in vitro. The profile of action of mephedrone on monoamine receptors and transporters suggests it could have a high abuse liability and several studies have found that mephedrone supports self-administration at a higher rate than MDMA. Overall, current data suggest that mephedrone not only differs from MDMA in its pharmacological profile, behavioural and neurotoxic effects, but also differs from other cathinones. © 2014 The British Pharmacological Society.

The world-wide move away from the didactic teaching of single disciples to integrated Problem-based Learning (PBL) curricula in medical education has posed challenges for the basic sciences. In this paper we identify two major challenges. The first challenge is the need to describe a core disciplinary curriculum that can be articulated and mapped onto the new structure. We illustrate how the British Pharmacological Society (BPS) Guidelines are used to evaluate the curriculum coverage in the medical course at The University of Melbourne. The second challenge is to ensure that foundational concepts are given adequate emphasis within the new structure, and in particular, that students have the opportunity to pursue these concepts in their self-directed learning. We illustrate one approach to teaching important pharmacological concepts in an integrated curriculum with a case study from the first year curriculum at The University of Melbourne. Finally, we propose the features of an integrated curriculum that facilitates the learning of basic pharmacology in a situation where PBL and integration sets the curriculum framework.

Ultraviolet radiation (UVR) contributes to the vast majority of nonmelanoma skin cancer (NMSC). As the incidence of NMSC continues to rise, topical therapies will be used with increasing frequency. Topical therapies may benefit high-risk surgical candidates as an alternative treatment modality and may improve overall cosmesis. The most commonly employed topical therapies are imiquimod, 5-fluorouracil (5-FU), and diclofenac. To review the detailed mechanism of action and side-effect profiles of each topical therapy used to treat NMSC and to explore newly discovered actions. Uncommon adverse events are also presented. An extensive literature search was performed to describe the pharmacologic actions of imiquimod, 5-FU, and diclofenac. A keen understanding of the pharmacologic concepts of these topical therapies may aid the dermatologic surgeon in making sound choices before, during, and after surgery. © 2011 by the American Society for Dermatologic Surgery, Inc.

Update on Treatment Guideline in Fibromyalgia Syndrome with Focus on Pharmacology

Directory of Open Access Journals (Sweden)

Sanam Kia

2017-05-01

Full Text Available Fibromyalgia syndrome (FMS is a chronic condition with unknown aetiology. The pathophysiology of the disease is incompletely understood; despite advances in our knowledge with regards to abnormal central and peripheral pain processing, and hypothalamo–pituitary–adrenal dysfunction, there is no clear specific pathophysiological therapeutic target. The management of this complex condition has thus perplexed the medical community for many years, and several national and international guidelines have aimed to address this complexity. The most recent guidelines from European League Against Rheumatism (EULAR (2016, Canadian Pain Society (2012, and The Association of the Scientific Medical Societies in Germany (AWMF (2012 highlight the change in attitudes regarding the overall approach to FMS, but offer varying advice with regards to the use of pharmacological agents. Amitriptyline, Pregabalin and Duloxetine are used most commonly in FMS and though modestly effective, are useful adjunctive treatment to non-pharmaceutical measures.

Tabernaemontana is a genus from the plant family, Apocynaceae with vast medicinal application and widespread distribution in the tropics and subtropics of Africa, Americas and Asia. The objective of this study is to critically evaluate the ethnobotany, medicinal uses, pharmacology and phytochemistry of the species, Tabernaemontana corymbosa (Roxb. ex Wall.) and provide information on the potential future application of alkaloids isolated from different parts of the plant. T. corymbosa (Roxb. ex Wall.) parts are used as poultice, boiled juice, decoctions and infusions for treatment against ulceration, fracture, post-natal recovery, syphilis, fever, tumours and orchitis in Malaysia, China, Thailand and Bangladesh. Studies recorded alkaloids as the predominant phytochemicals in addition to phenols, saponins and sterols with vast bioactivities such as antimicrobial, analgesic, anthelmintic, vasorelaxation, antiviral and cytotoxicity. An evaluation of scientific data and traditional medicine revealed the medicinal uses of different parts of T. corymbosa (Roxb. ex Wall.) across Asia. Future studies exploring the structure-bioactivity relationship of alkaloids such as jerantinine and vincamajicine among others could potentially improve the future application towards reversing anticancer drug resistance. © 2016 Royal Pharmaceutical Society, Journal of Pharmacy and Pharmacology.

Neuropathic pain in people with cancer (part 2): pharmacological and non-pharmacological management.

Taverner, Tarnia

2015-08-01

The aim of this paper is to provide an overview of the management of neuropathic pain associated with cancer and to provide helpful clinical advice for nurses working with patients who may have neuropathic pain. While cancer pain is a mixed-mechanism pain, this article will focus only on neuropathic pain management. The impact of neuropathic pain on patients' quality of life is great and while many patients recover from their cancer, a significant number continue to suffer from a neuropathic pain syndrome. Management of neuropathic pain is significantly different from management of nociceptive pain with respect to pharmacological and non-pharmacological strategies. Neuropathic pain is complex, and as such requires complex management using pharmacological as well as non-pharmacological approaches. Specific drugs for neuropathic pain may be effective for some patients, but not all; therefore, ongoing and comprehensive assessment and management are required. Furthermore, these patients may require trials of several drugs before they find one that works for them. It is important for nurses to understand neuropathic pain, its manifestation, impact on quality of life and management when nursing patients with neuropathic pain associated with cancer.

The Pharmacological Basis of Cannabis Therapy for Epilepsy.

Science.gov (United States)

Reddy, Doodipala Samba; Golub, Victoria M

2016-04-01

Recently, cannabis has been suggested as a potential alternative therapy for refractory epilepsy, which affects 30% of epilepsy, both adults and children, who do not respond to current medications. There is a large unmet medical need for new antiepileptics that would not interfere with normal function in patients with refractory epilepsy and conditions associated with refractory seizures. The two chief cannabinoids are Δ-9-tetrahyrdrocannabinol, the major psychoactive component of marijuana, and cannabidiol (CBD), the major nonpsychoactive component of marijuana. Claims of clinical efficacy in epilepsy of CBD-predominant cannabis or medical marijuana come mostly from limited studies, surveys, or case reports. However, the mechanisms underlying the antiepileptic efficacy of cannabis remain unclear. This article highlights the pharmacological basis of cannabis therapy, with an emphasis on the endocannabinoid mechanisms underlying the emerging neurotherapeutics of CBD in epilepsy. CBD is anticonvulsant, but it has a low affinity for the cannabinoid receptors CB1 and CB2; therefore the exact mechanism by which it affects seizures remains poorly understood. A rigorous clinical evaluation of pharmaceutical CBD products is needed to establish the safety and efficacy of their use in the treatment of epilepsy. Identification of mechanisms underlying the anticonvulsant efficacy of CBD is also critical for identifying other potential treatment options.

This study examined the feasibility of an interprofessional high-fidelity pharmacology simulation and its impact on pharmacy and nursing students' perceptions of interprofessionalism and pharmacology knowledge. Pharmacy and nursing students participated in a pharmacology simulation using a high-fidelity patient simulator. Faculty-facilitated debriefing included discussion of the case and collaboration. To determine the impact of the activity on students' perceptions of interprofessionalism and their ability to apply pharmacology knowledge, surveys were administered to students before and after the simulation. Attitudes Toward Health Care Teams scale (ATHCT) scores improved from 4.55 to 4.72 on a scale of 1-6 (p = 0.005). Almost all (over 90%) of the students stated their pharmacology knowledge and their ability to apply that knowledge improved following the simulation. A simulation in pharmacology is feasible and favorably affected students' interprofessionalism and pharmacology knowledge perceptions. Pharmacology is a core science course required by multiple health professions in early program curricula, making it favorable for incorporation of interprofessional learning experiences. However, reports of high-fidelity interprofessional simulation in pharmacology courses are limited. This manuscript contributes to the literature in the field of interprofessional education by demonstrating that an interprofessional simulation in pharmacology is feasible and can favorably affect students' perceptions of interprofessionalism. This manuscript provides an example of a pharmacology interprofessional simulation that faculty in other programs can use to build similar educational activities. Copyright © 2017 Elsevier Inc.

Pharmacological stress agents in nuclear cardiology

International Nuclear Information System (INIS)

Buscombe, J.R.

2004-01-01

Treadmill test combined with myocardial perfusion scintigraphy (MPS) is a commonly used technique in the assessment of coronary artery disease. However there are a group of patients who may not be able to undergo treadmill tests. Patients with underlying conditions like neuromuscular disease, musculoskeletal disorder, heart failure and end-stage renal disease (ESRD) on renal dialysis would find it difficult to perform exercise on a treadmill or bicycle ergometer. These conditions prevent them from performing adequate exercise. Such patients would benefit from pharmacological stress procedures combined with MPS. Nuclear medicine departments use various pharmacological agents while performing stress tests on cardiac patients. The most commonly used pharmacological agents for cardiac stress are coronary vasodilators and catecholamines. In addition to these agents, adjuvant use of nitrates and atropine is also a common practice in nuclear cardiology. This review addresses various physiological and pharmacological properties of the commonly used pharmacological stress agents in MPS and critically analyses their advantages and disadvantages, as well as their safety and efficacy.

Legros, Céline; Brasseur, Chantal; Delagrange, Philippe; Ducrot, Pierre; Nosjean, Olivier; Boutin, Jean A

2016-03-01

Melatonin exerts a variety of physiologic activities that are mainly relayed through the melatonin receptors MT1 and MT2 Low expressions of these receptors in tissues have led to widespread experimental use of the agonist 2-[(125)I]-iodomelatonin as a substitute for melatonin. We describe three iodinated ligands: 2-(2-[(2-iodo-4,5-dimethoxyphenyl)methyl]-4,5-dimethoxy phenyl) (DIV880) and (2-iodo-N-2-[5-methoxy-2-(naphthalen-1-yl)-1H-pyrrolo[3,2-b]pyridine-3-yl])acetamide (S70254), which are specific ligands at MT2 receptors, and N-[2-(5-methoxy-1H-indol-3-yl)ethyl]iodoacetamide (SD6), an analog of 2-[(125)I]-iodomelatonin with slightly different characteristics. Here, we further characterized these new ligands with regards to their molecular pharmacology. We performed binding experiments, saturation assays, association/dissociation rate measurements, and autoradiography using sheep and rat tissues and recombinant cell lines. Our results showed that [(125)I]-S70254 is receptor, and can be used with both cells and tissue. This radioligand can be used in autoradiography. Similarly, DIV880, a partial agonist [43% of melatonin on guanosine 5'-3-O-(thio)triphosphate binding assay], selective for MT2, can be used as a tool to selectively describe the pharmacology of this receptor in tissue samples. The molecular pharmacology of both human melatonin receptors MT1 and MT2, using a series of 24 ligands at these receptors and the new radioligands, did not lead to noticeable variations in the profiles. For the first time, we described radiolabeled tools that are specific for one of the melatonin receptors (MT2). These tools are amenable to binding experiments and to autoradiography using sheep or rat tissues. These specific tools will permit better understanding of the role and implication in physiopathologic processes of the melatonin receptors.

Pills or push-ups? Effectiveness and public perception of pharmacological and non-pharmacological cognitive enhancement

Directory of Open Access Journals (Sweden)

Lucius eCaviola

2015-12-01

Full Text Available We review work on the effectiveness of different forms of cognitive enhancement, both pharmacological and non-pharmacological. We consider caffeine, methylphenidate, and modafinil for pharmacological cognitive enhancement (PCE and computer training, physical exercise, and sleep for non-pharmacological cognitive enhancement (NPCE. We find that all of the techniques described can produce significant beneficial effects on cognitive performance. However, effect sizes are moderate, and consistently dependent on individual and situational factors as well as the cognitive domain in question. Although meta-analyses allowing a quantitative comparison of effectiveness across techniques are lacking to date, we can conclude that PCE is not more effective than NPCE. We discuss the physiological reasons for this limited effectiveness.We then propose that even though their actual effectiveness seems similar, in the general public PCE is perceived as fundamentally different from NPCE, in terms of effectiveness, but also in terms of acceptability. We illustrate the potential consequences such a misperception of PCE can have.

To explore potential study participants' views on willingness to join clinical trials of pharmacological interventions for illicit opioid use to inform and improve future recruitment strategies. Qualitative focus group study [six groups: oral methadone (two groups); buprenorphine tablets (two groups); injectable opioid agonist treatment (one group); and former opioid agonist treatment (one group)]. Drug and alcohol services and a peer support recovery service (London, UK). Forty people with experience of opioid agonist treatment for heroin dependence (26 males, 14 females; aged 33-66 years). Data collection was facilitated by a topic guide that explored willingness to enrol in clinical pharmacological trials. Groups were audio-recorded and transcribed. Transcribed data were analysed inductively via Iterative Categorization. Participants' willingness to join pharmacological trials of medications for opioid dependence was affected by factors relating to study burden, study drug, study design, study population and study relationships. Participants worried that the trial drug might be worse than, or interfere with, their current treatment. They also misunderstood aspects of trial design despite the researchers' explanations. Recruitment of participants for clinical trials of pharmacological interventions for illicit opioid use could be improved if researchers became better at explaining clinical trials to potential participants, dispelling misconceptions about trials and increasing trust in the research process and research establishment. A checklist of issues to consider when designing pharmacological trials for illicit opioid use is proposed. © 2018 The Authors.

2017-07-01

Cordia (family Boraginaceae) is a genus of deciduous flowering trees or shrubs comprising more than 300 species distributed widely in the tropical regions. The aim of this review was to provide exhaustive scientific information on traditional uses, phytochemistry and pharmacological activities of the 36 important species with medicinal value from the genus Cordia, to divulge prospects for further research on its therapeutic potential. Leaves, fruit, bark and seed of a majority of the species were found to possess abundant ethnomedicinal value, but leaves were found to be used most frequently to treat many ailments such as respiratory disorders, stomach pain, wound, inflammation, myalgia, cough, dysentery and diarrhoea. The phytochemical investigation of 36 species resulted in isolation of 293 chemical constituents from various chemical classes. The crude extracts, fractions, essential oils and pure compounds isolated from various Cordia species were reported to have a varied range of pharmacological activities. Many of the traditional uses of the genus Cordia were supported by the results obtained from pharmacological studies performed using various extracts or pure compounds. More attention should be given to the biological evaluation using pure phytochemicals and to identify the mechanism of actions and exploring this genus for new drug discovery. © 2017 Royal Pharmaceutical Society.

Stem cell therapy for cardiovascular disease: the demise of alchemy and rise of pharmacology.

Regenerative medicine holds great promise as a way of addressing the limitations of current treatments of ischaemic disease. In preclinical models, transplantation of different types of stem cells or progenitor cells results in improved recovery from ischaemia. Furthermore, experimental studies indicate that cell therapy influences a spectrum of processes, including neovascularization and cardiomyogenesis as well as inflammation, apoptosis and interstitial fibrosis. Thus, distinct strategies might be required for specific regenerative needs. Nonetheless, clinical studies have so far investigated a relatively small number of options, focusing mainly on the use of bone marrow-derived cells. Rapid clinical translation resulted in a number of small clinical trials that do not have sufficient power to address the therapeutic potential of the new approach. Moreover, full exploitation has been hindered so far by the absence of a solid theoretical framework and inadequate development plans. This article reviews the current knowledge on cell therapy and proposes a model theory for interpretation of experimental and clinical outcomes from a pharmacological perspective. Eventually, with an increased association between cell therapy and traditional pharmacotherapy, we will soon need to adopt a unified theory for understanding how the two practices additively interact for a patient's benefit. © 2012 The Authors.

Couvineau, Alain; Laburthe, Marc

2012-05-01

The vasoactive intestinal peptide (VIP) is a neuropeptide with wide distribution in both central and peripheral nervous systems, where it plays important regulatory role in many physiological processes. VIP displays a large biological functions including regulation of exocrine secretions, hormone release, fetal development, immune responses, etc. VIP appears to exert beneficial effect in neuro-degenerative and inflammatory diseases. The mechanism of action of VIP implicates two subtypes of receptors (VPAC1 and VPAC2), which are members of class B receptors belonging to the super-family of GPCR. This article reviews the current knowledge regarding the structure and molecular pharmacology of VPAC receptors. The structure-function relationship of VPAC1 receptor has been extensively studied, allowing to understand the molecular basis for receptor affinity, specificity, desensitization and coupling to adenylyl cyclase. Those studies have clearly demonstrated the crucial role of the N-terminal ectodomain (N-ted) of VPAC1 receptor in VIP recognition. By using different approaches including directed mutagenesis, photoaffinity labelling, NMR, molecular modelling and molecular dynamic simulation, it has been shown that the VIP molecule interacts with the N-ted of VPAC1 receptor, which is itself structured as a 'Sushi' domain. VPAC1 receptor also interacts with a few accessory proteins that play a role in cell signalling of receptors. Recent advances in the structural characterization of VPAC receptor and more generally of class B GPCRs will lead to the design of new molecules, which could have considerable interest for the treatment of inflammatory and neuro-degenerative diseases. © 2011 The Authors.

Haffey, Faye; Brady, Richard R W; Maxwell, Simon

2014-01-01

Junior doctors write the majority of hospital prescriptions but many indicate they feel underprepared to assume this responsibility and around 10% of prescriptions contain errors. Medical smartphone apps are now widely used in clinical practice and present an opportunity to provide support to inexperienced prescribers. This study assesses the contemporary range of smartphone apps with prescribing or related content. Six smartphone app stores were searched for apps aimed at the healthcare professional with drug, pharmacology or prescribing content. Three hundred and six apps were identified. 34% appeared to be for use within the clinical environment in order to aid prescribing, 14% out with the clinical setting and 51% of apps were deemed appropriate for both clinical and non-clinical use. Apps with drug reference material, such as textbooks, manuals or medical apps with drug information were the commonest apps found (51%), followed by apps offering drug or infusion rate dose calculation (26%). 68% of apps charged for download, with a mean price of £14.25 per app and a range of £0.62-101.90. A diverse range of pharmacology-themed apps are available and there is further potential for the development of contemporary apps to improve prescribing performance. Personalized app stores may help universities/healthcare organizations offer high quality apps to students to aid in pharmacology education. Users of prescribing apps must be aware of the lack of information regarding the medical expertise of app developers. This will enable them to make informed choices about the use of such apps in their clinical practice. © 2013 The British Pharmacological Society.

Animal experimentation is of considerable importance in pharmacology and cannot yet be avoided when studying complex, highly integrated physiological functions. The use of animals has been drastically reduced in the classical phases of pharmacological research, for example when comparing several compounds belonging to the same pharmacological class. However, animal experiments remain crucial for generating and validating new therapeutic concepts. Three examples of such research, conducted in strict ethical conditions, will be used to illustrate the different ways in which animal experimentation has contributed to human therapeutics.

Background Despite initial reports of a decline in use in the early 2000s, methamphetamine remains a significant public health concern with known neurotoxic and neurocognitive effects to the user. The goal of this review is to update the literature on methamphetamine use and addiction since its assent to peak popularity in 1990s. Methods Specifically, we first review recent epidemiological reports with a focus on methamphetamine accessibility, changes in use and disorder prevalence rates over time, and accurate estimates of the associated burden of care to the individual and society. Second, we review methamphetamine pharmacology literature with emphasis on the structural and functional neurotoxic effects associated with repeated use of the drug. Third, we briefly outline the findings on methamphetamine-related neurocognitive deficits as assessed via behavioral and neuroimaging paradigms. Lastly, we review the clinical presentation of methamphetamine addiction and the evidence supporting the available psychosocial and pharmacological treatments within the context of an addiction biology framework. Conclusion Taken together, this review provides a broad-based update of the available literature covering methamphetamine research over the past two decades and concludes with recommendations for future research.

Full Text Available Preliminary studies were carried out to investigate the role of filarial specific antibodies, raised in an animal model against the filarial parasite, Brugia malayi (sub-periodic, in blocking their early development in an experimental mosquito host, Aedes aegypti (Liverpool strain. In order to generate filarial specific antibodies, Mongolian gerbils, Meriones unguiculatus, were immunized either with live microfilariae (mf of B. malayi or their homogenate. Mf were harvested from the peritoneal cavity of Mongolian gerbils with patent infection of B. malayi and fed to A. aegypti along with the blood from immunized animals. Development of the parasite in infected mosquitoes was monitored until they reached infective stage larvae (L3. Fewer number of parasites developed to first stage (L1 and subsequently to L2 and L3 in mosquitoes fed with blood of immunized animals, when compared to those fed with blood of control animals. The results thus indicated that filarial parasite specific antibodies present in the blood of the immunized animals resulted in the reduction of number of larvae of B. malayi developing in the mosquito host.

Cognition refers to the mental processes involved in thinking, knowing, remembering, judging, and problem solving. Cognitive dysfunctions are an integral part of neuropsychiatric disorders as well as in healthy ageing. Cognitive Enhancers are molecules that help improve aspects of cognition like memory, intelligence, motivation, attention and concentration. Recently, Non Pharmacological Cognitive Enhancers have gained popularity as effective and safe alternative to various established drugs. Many of these Non Pharmacological Cognitive Enhancers seem to be more efficacious compared to currently available Pharmacological Cognitive Enhancers. This review describes and summarizes evidence on various Non Pharmacological Cognitive Enhancers such as physical exercise, sleep, meditation and yoga, spirituality, nutrients, computer training, brain stimulation, and music. We also discuss their role in ageing and different neuro-psychiatric disorders, and current status of Cochrane database recommendations. We searched the Pubmed database for the articles and reviews having the terms 'non pharmacological and cognitive' in the title, published from 2000 till 2014. A total of 11 results displayed, out of which 10 were relevant to the review. These were selected and reviewed. Appropriate cross-references within the articles along with Cochrane reviews were also considered and studied.

Cato Guldberg and Peter Waage, the history of the Law of Mass Action, and its relevance to clinical pharmacology.

Science.gov (United States)

Ferner, Robin E; Aronson, Jeffrey K

2016-01-01

We have traced the historical link between the Law of Mass Action and clinical pharmacology. The Law evolved from the work of the French chemist Claude Louis Berthollet, was first formulated by Cato Guldberg and Peter Waage in 1864 and later clarified by the Dutch chemist Jacobus van 't Hoff in 1877. It has profoundly influenced our qualitative and quantitative understanding of a number of physiological and pharmacological phenomena. According to the Law of Mass Action, the velocity of a chemical reaction depends on the concentrations of the reactants. At equilibrium the concentrations of the chemicals involved bear a constant relation to each other, described by the equilibrium constant, K. The Law of Mass Action is relevant to various physiological and pharmacological concepts, including concentration-effect curves, dose-response curves, and ligand-receptor binding curves, all of which are important in describing the pharmacological actions of medications, the Langmuir adsorption isotherm, which describes the binding of medications to proteins, activation curves for transmembrane ion transport, enzyme inhibition and the Henderson-Hasselbalch equation, which describes the relation between pH, as a measure of acidity and the concentrations of the contributory acids and bases. Guldberg and Waage recognized the importance of dynamic equilibrium, while others failed to do so. Their ideas, over 150 years old, are embedded in and still relevant to clinical pharmacology. Here we explain the ideas and in a subsequent paper show how they are relevant to understanding adverse drug reactions. © 2015 The British Pharmacological Society.

Pharmacological chaperoning: a primer on mechanism and pharmacology.

Approximately forty percent of diseases are attributable to protein misfolding, including those for which genetic mutation produces misfolding mutants. Intriguingly, many of these mutants are not terminally misfolded since native-like folding, and subsequent trafficking to functional locations, can be induced by target-specific, small molecules variably termed pharmacological chaperones, pharmacoperones, or pharmacochaperones (PCs). PC targets include enzymes, receptors, transporters, and ion channels, revealing the breadth of proteins that can be engaged by ligand-assisted folding. The purpose of this review is to provide an integrated primer of the diverse mechanisms and pharmacology of PCs. In this regard, we examine the structural mechanisms that underlie PC rescue of misfolding mutants, including the ability of PCs to act as surrogates for defective intramolecular interactions and, at the intermolecular level, overcome oligomerization deficiencies and dominant negative effects, as well as influence the subunit stoichiometry of heteropentameric receptors. Not surprisingly, PC-mediated structural correction of misfolding mutants normalizes interactions with molecular chaperones that participate in protein quality control and forward-trafficking. A variety of small molecules have proven to be efficacious PCs and the advantages and disadvantages of employing orthostatic antagonists, active-site inhibitors, orthostatic agonists, and allosteric modulator PCs are considered. Also examined is the possibility that several therapeutic agents may have unrecognized activity as PCs, and this chaperoning activity may mediate/contribute to therapeutic action and/or account for adverse effects. Lastly, we explore evidence that pharmacological chaperoning exploits intrinsic ligand-assisted folding mechanisms. Given the widespread applicability of PC rescue of mutants associated with protein folding disorders, both in vitro and in vivo, the therapeutic potential of PCs is vast

Caralluma is a xerophytic genus used as traditional medicine for the treatment of diabetes, inflammation, leprosy, obesity and rheumatism. Objectives of this review are to establish a relationship between traditional uses and scientific studies by critically evaluating the available fragmented literature on ethnobotany, pharmacology, phytochemistry and toxicology of genus Caralluma. Ethnomedical uses of Caralluma have been recorded from various countries such as China, India, Iran and Pakistan for six major classes of diseases including diabetes and gastrointestinal disorders. This review indicated the efficacy of genus Caralluma in several in vitro and in vivo pharmacological properties such as antimicrobial, antioxidant and anticancer activity. These bioactivity might be due to the presence of certain classes of compounds in genus Caralluma including pregnane glycosides, flavonoid glycosides and flavones. Traditional uses and scientific evaluation of Caralluma indicates that it is one of the most widely used genus in some parts of the world. Further studies on the structural activity relationship of some of the isolated compound may improve their biological potency as well as scientific exploitation of traditional uses of the genus. © 2014 Royal Pharmaceutical Society.

Pharmacological interactions of vasoconstrictors.

Gómez-Moreno, Gerardo; Guardia, Javier; Cutando, Antonio; Calvo-Guirado, José Luis

2009-01-01

This article is the first of a series on pharmacological interactions involving medicaments commonly prescribed and/or used in odontology: vasoconstrictors in local anaesthetics and anti-inflammatory and anti-microbial analgesics. The necessity for the odontologist to be aware of adverse reactions as a result of the pharmacological interactions is due to the increase in medicament consumption by the general population. There is a demographic change with greater life expectancy and patients have increased chronic health problems and therefore have increased medicament intake. The presence of adrenaline (epinephrine) and other vasoconstrictors in local odontological anaesthetics is beneficial in relation to the duration and depth of anaesthesia and reduces bleeding and systemic toxicity of the local anaesthetic. However, it might produce pharmacological interactions between the injected vasoconstrictors and the local anaesthetic and adrenergic medicament administered exogenically which the odontologist should be aware of, especially because of the risk of consequent adverse reactions. Therefore the importance of conducting a detailed clinical history of the general state of health and include all medicaments, legal as well as illegal, taken by the patient.

Effective teaching in pharmacology and clinical pharmacology and therapeutics (CPT) is necessary to make medical students competent prescribers. However, the current structure, delivery, and assessment of CPT education in the European Union (EU) is unknown. We sent an online questionnaire to teachers with overall responsibility for CPT education in EU medical schools. Questions focused on undergraduate teaching and assessment of CPT, and students' preparedness for prescribing. In all, 185 medical schools (64%) from 27 EU countries responded. Traditional learning methods were mainly used. The majority of respondents did not provide students with the opportunity to practice real-life prescribing and believed that their students were not well prepared for prescribing. There is a marked difference in the quality and quantity of CPT education within and between EU countries, suggesting that there is considerable scope for improvement. A collaborative approach should be adopted to harmonize and modernize the undergraduate CPT education across the EU. © 2017 The Authors Clinical Pharmacology & Therapeutics published by Wiley Periodicals, Inc. on behalf of American Society for Clinical Pharmacology and Therapeutics.

Pharmacology Goes Concept-Based: Course Design, Implementation, and Evaluation.

Science.gov (United States)

Lanz, Amelia; Davis, Rebecca G

Although concept-based curricula are frequently discussed in the nursing education literature, little information exists to guide the development of a concept-based pharmacology course. Traditionally, nursing pharmacology courses are taught with an emphasis on drug class where a prototype drug serves as an exemplar. When transitioning pharmacology to a concept-based course, special considerations are in order. How can educators successfully integrate essential pharmacological content into a curriculum structured around nursing concepts? This article presents one approach to the design and implementation of a concept-based undergraduate pharmacology course. Planning methods, supportive teaching strategies, and course evaluation procedures are discussed.

Bradykinin has been implicated as a mediator of the acute pathophysiological and inflammatory consequences of respiratory tract infections and in exacerbations of chronic diseases such as asthma. Bradykinin may also be a trigger for the coughing associated with these and other conditions. We have thus set out to evaluate the pharmacology of bradykinin-evoked coughing in guinea pigs. When inhaled, bradykinin induced paroxysmal coughing that was abolished by the bradykinin B2 receptor antagonist HOE 140. These cough responses rapidly desensitized, consistent with reports of B2 receptor desensitization. Bradykinin-evoked cough was potentiated by inhibition of both neutral endopeptidase and angiotensin-converting enzyme (with thiorphan and captopril, respectively), but was largely unaffected by muscarinic or thromboxane receptor blockade (atropine and ICI 192605), cyclooxygenase, or nitric oxide synthase inhibition (meclofenamic acid and N(G)-nitro-L-arginine). Calcium influx studies in bronchopulmonary vagal afferent neurons dissociated from vagal sensory ganglia indicated that the tachykinin-containing C-fibers arising from the jugular ganglia mediate bradykinin-evoked coughing. Also implicating the jugular C-fibers was the observation that simultaneous blockade of neurokinin2 (NK2; SR48968) and NK3 (SR142801 or SB223412) receptors nearly abolished the bradykinin-evoked cough responses. The data suggest that bradykinin induces coughing in guinea pigs by activating B2 receptors on bronchopulmonary C-fibers. We speculate that therapeutics targeting the actions of bradykinin may prove useful in the treatment of cough.

This is a report on a symposium sponsored by the American Society for Pharmacology and Experimental Therapeutics and held at the Experimental Biology 2012 meeting in San Diego, California, on April 25, 2012. The symposium speakers summarized and critically evaluated our current understanding of the physiologic, pharmacological, and toxicological roles of NADPH–cytochrome P450 oxidoreductase (POR), a flavoprotein involved in electron transfer to microsomal cytochromes P450 (P450), cytochrome b5, squalene mono-oxygenase, and heme oxygenase. Considerable insight has been derived from the development and characterization of mouse models with conditional Por deletion in particular tissues or partial suppression of POR expression in all tissues. Additional mouse models with global or conditional hepatic deletion of cytochrome b5 are helping to clarify the P450 isoform- and substrate-specific influences of cytochrome b5 on P450 electron transfer and catalytic function. This symposium also considered studies using siRNA to suppress POR expression in a hepatoma cell–culture model to explore the basis of the hepatic lipidosis phenotype observed in mice with conditional deletion of Por in liver. The symposium concluded with a strong translational perspective, relating the basic science of human POR structure and function to the impacts of POR genetic variation on human drug and steroid metabolism.

Pharmacotherapy concerns and other factors with a bearing on patient selection for kidney transplantation are discussed. The process of selecting appropriate candidates for kidney transplantation involves multidisciplinary assessment to evaluate a patient's mental, social, physical, financial, and medical readiness for successful surgery and good posttransplantation outcomes. Transplantation pharmacists can play important roles in the recognition and stratification of pharmacologic and nonpharmacologic risks in prospective kidney transplant recipients and the identification of issues that require a mitigation strategy. Key pharmacotherapy-related issues and considerations during the risk assessment process include (1) anticoagulation concerns, (2) cytochrome P-450 isoenzyme-mediated drug interactions, (3) mental health-related medication use, (4) chronic pain-related medication use, (5) medication allergies, (6) use of hormonal contraception and replacement therapy, (7) prior or current use of immunosuppressants, (8) issues with drug absorption, (9) alcohol use, (10) tobacco use, (11) active use of illicit substances, and (12) use of herbal supplements. Important areas of nonpharmacologic risk include vaccine delivery, infection prophylaxis and treatment, and socially related factors such as nonadherent behavior, communication barriers, and financial, insurance, or transportation challenges that can compromise posttransplantation outcomes. Consensus opinions of practitioners in transplantation pharmacy regarding the pharmacologic and nonpharmacologic factors that should be considered in assessing candidates for kidney transplantation are presented.

The Jordanian 'Melissa', (Aloysia citrodora) has been poorly studied both pharmacologically and in the clinic. Essential oils (EO) derived from leaves of A. citrodora were obtained by hydrodistillation, analysed by gas chromatography-mass spectrometry (GC-MS) and were investigated for a range of neurobiological and pharmacological properties, as a basis for potential future use in drug discovery. A selection of central nervous system (CNS) receptor-binding profiles was carried out. Antioxidant activity and ferrous iron-chelating assays were adopted, and the neuroprotective properties of A. citrodora EO assessed using hydrogen peroxide-induced and β-amyloid-induced neurotoxicity with the CAD (Cath.-a-differentiated) neuroblastoma cell line. The major chemical components detected in the A. citrodora EOs, derived from dried and fresh leaves, included limonene, geranial, neral, 1, 8-cineole, curcumene, spathulenol and caryophyllene oxide, respectively. A. citrodora leaf EO inhibited [(3) H] nicotine binding to well washed rat forebrain membranes, and increased iron-chelation in vitro. A. citrodora EO displays effective antioxidant, radical-scavenging activities and significant protective properties vs both hydrogen peroxide- and β-amyloid-induced neurotoxicity. A. citrodora EO displays a range of pharmacological properties worthy of further investigation to isolate the compounds responsible for the observed neuroactivities, to further analyse their mode of action and determine their clinical potential in neurodegenerative diseases. © 2015 Royal Pharmaceutical Society.

The Safety Pharmacology Society (SPS) and National Centre for the Replacement, Refinement & Reduction of Animals in Research (NC3Rs) conducted a survey and workshop in 2015 to define current industry practices relating to housing of non-rodents during telemetry recordings in safety pharmacology and toxicology studies. The aim was to share experiences, canvas opinion on the study procedures/designs that could be used and explore the barriers to social housing. Thirty-nine sites, either running studies (Sponsors or Contract Research Organisations, CROs) and/or outsourcing work responded to the survey (51% from Europe; 41% from USA). During safety pharmacology studies, 84, 67 and 100% of respondents socially house dogs, minipigs and non-human primates (NHPs) respectively on non-recording days. However, on recording days 20, 20 and 33% of respondents socially house the animals, respectively. The main barriers for social housing were limitations in the recording equipment used, study design and animal temperament/activity. During toxicology studies, 94, 100 and 100% of respondents socially house dogs, minipigs and NHPs respectively on non-recording days. However, on recording days 31, 25 and 50% of respondents socially house the animals, respectively. The main barriers for social housing were risk of damage to and limitations in the recording equipment used, food consumption recording and temperament/activity of the animals. Although the majority of the industry does not yet socially house animals during telemetry recordings in safety pharmacology and toxicology studies, there is support to implement this refinement. Continued discussions, sharing of best practice and data from companies already socially housing, combined with technology improvements and investments in infrastructure are required to maintain the forward momentum of this refinement across the industry.

Pharmacology national board examinations: factors that may influence performance.

Science.gov (United States)

Neidle, E A; Kahn, N

1977-12-01

Data from a survey of pharmacology courses in 60 dental schools were used to determine whether certain teaching variables affect performance in pharmacology National Board examinations. In addition, three-year class-averaged pharmacology scores and, rarely, one-year averaged scores were correlated with several admissions variables. While correlations between some admissions variables and pharmacology scores were quite good, the averaged pharmacology scores were not powerfully affected by course length, placement of the course in the curriculum, length of the curriculum, or the presence of a dentally trained pharmacologist in the department. It is suggested that other factors, related to the student and his capabilities, influence performance on National Boards. Dental pharmacology courses should be designed to given students the best possible exposure to an important basic science, not to make them perform well on National Boards, because student performance on National Boards may be independent of the nature of the didactic courses.

G protein-coupled receptors are important regulators of cellular signaling processes. Within the large family of rhodopsin-like receptors, those binding to biogenic amines form a discrete subgroup. Activation of biogenic amine receptors leads to transient changes of intracellular Ca²⁺-([Ca²⁺](i)) or 3',5'-cyclic adenosine monophosphate ([cAMP](i)) concentrations. Both second messengers modulate cellular signaling processes and thereby contribute to long-lasting behavioral effects in an organism. In vivo pharmacology has helped to reveal the functional effects of different biogenic amines in honeybees. The phenolamine octopamine is an important modulator of behavior. Binding of octopamine to its receptors causes elevation of [Ca²⁺](i) or [cAMP](i). To date, only one honeybee octopamine receptor that induces Ca²⁺ signals has been molecularly and pharmacologically characterized. Here, we examined the pharmacological properties of four additional honeybee octopamine receptors. When heterologously expressed, all receptors induced cAMP production after binding to octopamine with EC₅₀(s) in the nanomolar range. Receptor activity was most efficiently blocked by mianserin, a substance with antidepressant activity in vertebrates. The rank order of inhibitory potency for potential receptor antagonists was very similar on all four honeybee receptors with mianserin > cyproheptadine > metoclopramide > chlorpromazine > phentolamine. The subroot of octopamine receptors activating adenylyl cyclases is the largest that has so far been characterized in arthropods, and it should now be possible to unravel the contribution of individual receptors to the physiology and behavior of honeybees. © 2013 International Society for Neurochemistry.

Healthy functioning relies on a variety of perceptual, cognitive, emotional, and behavioral abilities that are distributed throughout the normal population. Variation in these traits define the wide range of neurodevelopmental (NDD) and neuropsychiatric (NPD) disorders. Here, we introduce a new measure for assessing these traits in typically developing children and children at risk for NDD and NPD from age 2 to 18 years. The Childhood Oxford-Liverpool Inventory of Feelings and Experiences (CO-LIFE) was created as a dimensional, parent-report measure of schizotypal and psychotic traits in the general population. Parents of 2,786 children also self-reported on an adapted version of the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE-US). The CO-LIFE resulted in continuous distributions for the total score and for each of three factor analytically-derived subscales. Item response theory (IRT) analyses indicated strong reliability across the score range for the O-LIFE-US and the CO-LIFE. Internal consistency and test-retest reliability were high across all scales. Parent-child intraclass correlations were consistent with high heritability. The scales discriminated participants who reported a lifetime psychiatric diagnosis from those who reported no diagnosis. The O-LIFE-US and CO-LIFE scores correlated positively with the Social Responsiveness Scale 2 (SRS-2) indicating good convergent validity. Like the original O-LIFE, the O-LIFE-US and the CO-LIFE are valid and reliable tools that reflect the spectrum of psychiatric and schizotypal traits in the general population. Such scales are necessary for conducting family studies that aim to examine a range of psychological and behavioral traits in both children and adults and are well-suited for the Research Domain Criteria (RDoC) initiative of the NIMH. © 2017 Association for Child and Adolescent Mental Health.

Venomous animals occupy one of the most successful evolutionary niches and occur on nearly every continent. They deliver venoms via biting and stinging apparatuses with the aim to rapidly incapacitate prey and deter predators. This has led to the evolution of venom components that act at a number of biological targets - including ion channels, G-protein coupled receptors, transporters and enzymes - with exquisite selectivity and potency, making venom-derived components attractive pharmacological tool compounds and drug leads. In recent years, plate-based pharmacological screening approaches have been introduced to accelerate venom-derived drug discovery. A range of assays are amenable to this purpose, including high-throughput electrophysiology, fluorescence-based functional and binding assays. However, despite these technological advances, the traditional activity-guided fractionation approach is time-consuming and resource-intensive. The combination of screening techniques suitable for miniaturization with sequence-based discovery approaches - supported by advanced proteomics, mass spectrometry, chromatography as well as synthesis and expression techniques - promises to further improve venom peptide discovery. Here, we discuss practical aspects of establishing a pipeline for venom peptide drug discovery with a particular emphasis on pharmacology and pharmacological screening approaches.

Full Text Available Clozapine is the drug of choice for drug-resistant schizophrenia, but despite its use, 30-40% patients fail to achieve satisfactory therapeutic effects. In such situations, augmentation attempts are made by both pharmacological and non-pharmacological methods. To date, most of the work has been devoted to pharmacological strategies, much less to augemantation of clozapine with electroconvulsive therapy (C+ECT, transcranial direct current stimulation (tDCS or transcranial magnetic stimulation (TMS.

Myofibroblasts are one of the primary cell types responsible for the accumulation of extracellular matrix in fibrosing diseases, and targeting myofibroblast differentiation is an important therapeutic strategy for the treatment of pulmonary fibrosis. Transforming growth factor-β (TGF-β) has been shown to be an important inducer of myofibroblast differentiation. We previously demonstrated that lactate dehydrogenase and its metabolic product lactic acid are important mediators of myofibroblast differentiation, via acid-induced activation of latent TGF-β. Here we explore whether pharmacologic inhibition of LDH activity can prevent TGF-β-induced myofibroblast differentiation. Primary human lung fibroblasts from healthy patients and those with pulmonary fibrosis were treated with TGF-β and or gossypol, an LDH inhibitor. Protein and RNA were analyzed for markers of myofibroblast differentiation and extracellular matrix generation. Gossypol inhibited TGF-β-induced expression of the myofibroblast marker α-smooth muscle actin (α-SMA) in a dose-dependent manner in both healthy and fibrotic human lung fibroblasts. Gossypol also inhibited expression of collagen 1, collagen 3, and fibronectin. Gossypol inhibited LDH activity, the generation of extracellular lactic acid, and the rate of extracellular acidification in a dose-dependent manner. Furthermore, gossypol inhibited TGF-β bioactivity in a dose-dependent manner. Concurrent treatment with an LDH siRNA increased the ability of gossypol to inhibit TGF-β-induced myofibroblast differentiation. Gossypol inhibits TGF-β-induced myofibroblast differentiation through inhibition of LDH, inhibition of extracellular accumulation of lactic acid, and inhibition of TGF-β bioactivity. These data support the hypothesis that pharmacologic inhibition of LDH may play an important role in the treatment of pulmonary fibrosis. Copyright © 2015 the American Physiological Society.

Behavioral training in neurofeedback has proven to be an essential complement to generalize the effects of pharmacological support in subjects who have attention deficit with hyperactivity disorder (ADHD). Therefore, this investigation attempts to analyze the efficacy of neurofeedback compared with pharmacological support and the combination of both. Participants were 131 students, classified into four groups: control (did not receive neurofeedback or pharmacological support), neurofeedback group, pharmacological support group, and combined group (neurofeedback + pharmacological support). Participants' executive control and cortical activation were assessed before and after treatment. Results indicate that the combined group obtained more benefits and that the neurofeedback group improved to a greater extent in executive control than the pharmacological support group. It is concluded that this kind of training may be an alternative to stimulate activation in subjects with ADHD.

Pharmacology and function of melatonin receptors

International Nuclear Information System (INIS)

Dubocovich, M.L.

1988-01-01

The hormone melatonin is secreted primarily from the pineal gland, with highest levels occurring during the dark period of a circadian cycle. This hormone, through an action in the brain, appears to be involved in the regulation of various neural and endocrine processes that are cued by the daily change in photoperiod. This article reviews the pharmacological characteristics and function of melatonin receptors in the central nervous system, and the role of melatonin in mediating physiological functions in mammals. Melatonin and melatonin agonists, at picomolar concentrations, inhibit the release of dopamine from retina through activation of a site that is pharmacologically different from a serotonin receptor. These inhibitory effects are antagonized by the novel melatonin receptor antagonist luzindole (N-0774), which suggests that melatonin activates a presynaptic melatonin receptor. In chicken and rabbit retina, the pharmacological characteristics of the presynaptic melatonin receptor and the site labeled by 2-[125I]iodomelatonin are identical. It is proposed that 2-[125I]iodomelatonin binding sites (e.g., chicken brain) that possess the pharmacological characteristics of the retinal melatonin receptor site (order of affinities: 2-iodomelatonin greater than 6-chloromelatonin greater than or equal to melatonin greater than or equal to 6,7-di-chloro-2-methylmelatonin greater than 6-hydroxymelatonin greater than or equal to 6-methoxymelatonin greater than N-acetyltryptamine greater than or equal to luzindole greater than N-acetyl-5-hydroxytryptamine greater than 5-methoxytryptamine much greater than 5-hydroxytryptamine) be classified as ML-1 (melatonin 1). The 2-[125I]iodomelatonin binding site of hamster brain membranes possesses different binding and pharmacological characteristics from the retinal melatonin receptor site and should be classified as ML-2. 64 references

NADPH oxidases as novel pharmacologic targets against influenza A virus infection.

Science.gov (United States)

Vlahos, Ross; Selemidis, Stavros

2014-12-01

Influenza A viruses represent a major global health care challenge, with imminent pandemics, emerging antiviral resistance, and long lag times for vaccine development, raising a pressing need for novel pharmacologic strategies that ideally target the pathology irrespective of the infecting strain. Reactive oxygen species (ROS) pervade all facets of cell biology with both detrimental and protective properties. Indeed, there is compelling evidence that activation of the NADPH oxidase 2 (NOX2) isoform of the NADPH oxidase family of ROS-producing enzymes promotes lung oxidative stress, inflammation, injury, and dysfunction resulting from influenza A viruses of low to high pathogenicity, as well as impeding virus clearance. By contrast, the dual oxidase isoforms produce ROS that provide vital protective antiviral effects for the host. In this review, we propose that inhibitors of NOX2 are better alternatives than broad-spectrum antioxidant approaches for treatment of influenza pathologies, for which clinical efficacy may have been limited owing to poor bioavailability and inadvertent removal of beneficial ROS. Finally, we briefly describe the current suite of NADPH oxidase inhibitors and the molecular features of the NADPH oxidase enzymes that could be exploited by drug discovery for development of more specific and novel inhibitors to prevent or treat disease caused by influenza.

This is an update of the Cochrane review "Pharmacologic treatment for memory disorder in multiple sclerosis" (first published in The Cochrane Library 2011, Issue 10).Multiple sclerosis (MS) is a chronic immune-mediated, inflammatory, demyelinating, neurodegenerative disorder of the central nervous system (CNS) and can cause both neurological and neuropsychological disability. Both demyelination and axonal and neuronal loss are believed to contribute to MS-related cognitive impairment. Memory disorder is one of the most frequent cognitive dysfunctions and presents a considerable burden to people with MS and to society due to the negative impact on function. A number of pharmacological agents have been evaluated in many existing randomised controlled trials for their efficacy on memory disorder in people with MS but the results were not consistent. To assess the absolute and comparative efficacy, tolerability and safety of pharmacological treatments for memory disorder in adults with MS. We searched the Cochrane Multiple Sclerosis and Rare Diseases of the Central Nervous System Group Trials Register (24 July 2013), PsycINFO (January 1980 to 26 June 2013) and CBMdisc (1978 to 24 June 2013), and checked reference lists of identified articles, searched some relevant journals manually, registers of clinical trials and published abstracts of conference proceedings. All double-blind, randomised controlled parallel trials on pharmacological treatment versus placebo or one or more pharmacological treatments in adults with MS who had at least mild memory impairment (at 0.5 standard deviations below age- and sex-based normative data on a validated memory scale). We placed no restrictions regarding dose, route of administration and frequency; however, we only included trials with an administration duration of 12 weeks or greater. Two review authors independently assessed trial quality and extracted data. We discussed disagreements and resolved them by consensus among review

Abstract Despite substantial investments by government, philanthropic, and commercial sources over the past several decades, traumatic brain injury (TBI) remains an unmet medical need and a major source of disability and mortality in both developed and developing societies. The U.S. Department of Defense neurotrauma research portfolio contains more than 500 research projects funded at more than $700 million and is aimed at developing interventions that mitigate the effects of trauma to the nervous system and lead to improved quality of life outcomes. A key area of this portfolio focuses on the need for effective pharmacological approaches for treating patients with TBI and its associated symptoms. The Neurotrauma Pharmacology Workgroup was established by the U.S. Army Medical Research and Materiel Command (USAMRMC) with the overarching goal of providing a strategic research plan for developing pharmacological treatments that improve clinical outcomes after TBI. To inform this plan, the Workgroup (a) assessed the current state of the science and ongoing research and (b) identified research gaps to inform future development of research priorities for the neurotrauma research portfolio. The Workgroup identified the six most critical research priority areas in the field of pharmacological treatment for persons with TBI. The priority areas represent parallel efforts needed to advance clinical care; each requires independent effort and sufficient investment. These priority areas will help the USAMRMC and other funding agencies strategically guide their research portfolios to ensure the development of effective pharmacological approaches for treating patients with TBI.

Mitchell, Gary; Agnelli, Joanne

2015-11-25

Distress is one of the most common clinical manifestations associated with dementia. Pharmacological intervention may be appropriate in managing distress in some people. However, best practice guidelines advocate non-pharmacological interventions as the preferred first-line treatment. The use of non-pharmacological interventions encourages healthcare professionals to be more person-centred in their approach, while considering the causes of distress. This article provides healthcare professionals with an overview of some of the non-pharmacological approaches that can assist in alleviating distress for people living with dementia including: reminiscence therapy, reality orientation, validation therapy, music therapy, horticultural therapy, doll therapy and pet therapy. It provides a summary of their use in clinical practice and links to the relevant literature.

Breastfeeding information in pharmacology textbooks: a content analysis.

Amir, Lisa H; Raval, Manjri; Hussainy, Safeera Y

2013-07-01

Women often need to take medicines while breastfeeding and pharmacists need to provide accurate information in order to avoid undue caution about the compatibility of medicines and breastfeeding. The objective of this study was to review information provided about breastfeeding in commonly used pharmacology textbooks. We asked 15 Australian universities teaching pharmacy courses to provide a list of recommended pharmacology textbooks in 2011. Ten universities responded, generating a list of 11 textbooks that we analysed for content relating to breastfeeding. Pharmacology textbooks outline the mechanisms of actions of medicines and their use: however, only a small emphasis is placed on the safety/compatibility of medicines for women during breastfeeding. Current pharmacology textbooks recommended by Australian universities have significant gaps in their coverage of medicine use in breastfeeding. Authors of textbooks should address this gap, so academic staff can recommend texts with the best lactation content.

Information overload and recent curricular changes are viewed as important contributory factors to insufficient pharmacological education of medical students. This study was designed to assess the effectiveness of pharmacology teaching in our medical school. The study subjects were 455 second-year medical students, class of 2010, and 26 pharmacology teachers at the National University of Mexico Medical School. To assess pharmacological knowledge, students were required to take 3 multiple-choice exams (70 questions each) as part of their evaluation in the pharmacology course. A 30-item questionnaire was used to explore the students' opinion on teaching. Pharmacology professors evaluated themselves using a similar questionnaire. Students and teachers rated each statement on a 5-point Likert scale. The groups' exam scores ranged from 54.5% to 90.0% of correct responses, with a mean score of 77.3%. Only 73 (16%) of 455 students obtained an exam score of 90% and higher. Students' evaluations of faculty and professor self-ratings were very high (90% and 96.2%, of the maximal response, respectively). Student and professor ratings were not correlated with exam scores (r = 0.291). Our study shows that knowledge on pharmacology is incomplete in a large proportion of second-year medical students and indicates that there is an urgent need to review undergraduate training in pharmacology. The lack of relationship between the subjective ratings of teacher effectiveness and objective exam scores suggests the use of more demanding measures to assess the effectiveness of teaching.

Pharmacological effects of biotin.

Science.gov (United States)

Fernandez-Mejia, Cristina

2005-07-01

In the last few decades, more vitamin-mediated effects have been discovered at the level of gene expression. Increasing knowledge on the molecular mechanisms of these vitamins has opened new perspectives that form a connection between nutritional signals and the development of new therapeutic agents. Besides its role as a carboxylase prosthetic group, biotin regulates gene expression and has a wide repertoire of effects on systemic processes. The vitamin regulates genes that are critical in the regulation of intermediary metabolism: Biotin has stimulatory effects on genes whose action favors hypoglycemia (insulin, insulin receptor, pancreatic and hepatic glucokinase); on the contrary, biotin decreases the expression of hepatic phosphoenolpyruvate carboxykinase, a key gluconeogenic enzyme that stimulates glucose production by the liver. The findings that biotin regulates the expression of genes that are critical in the regulation of intermediary metabolism are in agreement with several observations that indicate that biotin supply is involved in glucose and lipid homeostasis. Biotin deficiency has been linked to impaired glucose tolerance and decreased utilization of glucose. On the other hand, the diabetic state appears to be ameliorated by pharmacological doses of biotin. Likewise, pharmacological doses of biotin appear to decrease plasma lipid concentrations and modify lipid metabolism. The effects of biotin on carbohydrate metabolism and the lack of toxic effects of the vitamin at pharmacological doses suggest that biotin could be used in the development of new therapeutics in the treatment of hyperglycemia and hyperlipidemia, an area that we are actively investigating.

Why is the Liverpool care pathway used for some dying cancer patients and not others? Healthcare professionals’ perspectives

Directory of Open Access Journals (Sweden)

Freemantle Alison

2012-09-01

Full Text Available Abstract Background Despite evidence suggesting that the Liverpool Care Pathway for the Dying Patient is a structured and proficient means of supporting care delivery in the last hours or days of life, discrepancies in uptake are widespread. This exploratory study sought to understand why patients dying of cancer in oncology wards of one hospital trust were, or were not, supported by the LCP. A purposive qualitative case study design was used; each case represented a patient who had died and their most involved nurse and doctor. In-depth interviews explored both recollections of the ‘case’ and wider experiences of using the Pathway in end-of-life care. Eleven healthcare professionals were interviewed about their involvement in the end-of-life care of six patients. For four of these patients care was supported by the LCP. Findings Although doctors and nurses reported they preferred to use the Pathway to ensure comfortable death, an important factor influencing their decisions was time of death. Access to timely senior review was regarded as an essential preliminary to placing patients on the Pathway but delayed access ‘out of hours’ was commonly experienced and tensions arose from balancing conflicting priorities. Consequently, the needs of dying patients sometimes failed to compete with those receiving curative treatment. Conclusions This study suggests that greater attention should be focused on ‘out of hours’ care in hospitals to ensure regular senior review of all patients at risk of dying and to support front line staff to communicate effectively and make contingency plans focused on patients’ best interests.

academic centers. Evaluations by faculty and students have been overwhelmingly positive. Requests to use the CPPS units in various clinical pharmacology teaching programs were received from numerous schools within the United States and from abroad. The third teaching clinic in September 1995 included a follow-up focused on the uses of drug information databases in case problem exercises. These examples are presented to demonstrate the variety of educational activities the American College of Clinical Pharmacology is sponsoring to fulfill its strategic initiative dedicated to offer innovative teaching programs and to develop new teaching materials in clinical pharmacology. Collectively, all of the teaching clinics, symposia, and workshop efforts, sponsored by the various academic professional societies alone or together over the past decade, are necessary if new and innovative teaching materials in the field of basic science and in the fields of pharmacology and clinical pharmacology are to be continuously developed to keep pace with the new, rapidly changing developments in medicine to provide the best treatment for patients in the 21st century.

Branch, Marc N

2006-05-01

Behavioral pharmacology is a maturing science that has made significant contributions to the study of drug effects on behavior, especially in the domain of drug-behavior interactions. Less appreciated is that research in behavioral pharmacology can have, and has had, implications for the experimental analysis of behavior, especially its conceptualizations and theory. In this article, I outline three general strategies in behavioral pharmacology research that have been employed to increase understanding of behavioral processes. Examples are provided of the general characteristics of the strategies and of implications of previous research for behavior theory. Behavior analysis will advance as its theories are challenged.

Recent Pharmacology Studies on the International Space Station

The environment on the International Space Station (ISS) includes a variety of potential stressors including the absence of Earth's gravity, elevated exposure to radiation, confined living and working quarters, a heavy workload, and high public visibility. The effects of this extreme environment on pharmacokinetics, pharmacodynamics, and even on stored medication doses, are not yet understood. Dr. Wotring will discuss recent analyses of medication doses that experienced long duration storage on the ISS and a recent retrospective examination of medication use during long-duration spaceflights. She will also describe new pharmacology experiments that are scheduled for upcoming ISS missions. Dr. Virginia E. Wotring is a Senior Scientist in the Division of Space Life Sciences in the Universities Space Research Association, and Pharmacology Discipline Lead at NASA's Johnson Space Center, Human Heath and Countermeasures Division.

Emotional Modulation of Learning and Memory: Pharmacological Implications.

LaLumiere, Ryan T; McGaugh, James L; McIntyre, Christa K

2017-07-01

Memory consolidation involves the process by which newly acquired information becomes stored in a long-lasting fashion. Evidence acquired over the past several decades, especially from studies using post-training drug administration, indicates that emotional arousal during the consolidation period influences and enhances the strength of the memory and that multiple different chemical signaling systems participate in this process. The mechanisms underlying the emotional influences on memory involve the release of stress hormones and activation of the basolateral amygdala, which work together to modulate memory consolidation. Moreover, work suggests that this amygdala-based memory modulation occurs with numerous types of learning and involves interactions with many different brain regions to alter consolidation. Additionally, studies suggest that emotional arousal and amygdala activity in particular influence synaptic plasticity and associated proteins in downstream brain regions. This review considers the historical understanding for memory modulation and cellular consolidation processes and examines several research areas currently using this foundational knowledge to develop therapeutic treatments.

Ramos Cordero, Primitivo; López Trigo, José Antonio; Maíllo Pedraz, Herminio; Paz Rubio, José María

2015-01-01

Physical and pharmacological restraints are a controversial issue in the context of geriatric care due to their moral, ethical, social and legal repercussions and, despite this fact, no specific legislation exists at a national level. The use of restraints is being questioned with growing frequency, as there are studies that demonstrate that restraints do not reduce the number of falls or their consequences, but rather can increase them, cause complications, injuries and potentially fatal accidents. Restraints are not always used rationally, despite compromising a fundamental human right, that is, freedom, protected in the Constitution, as well as values and principles, such as dignity and personal self-esteem. There are centers where restraints are applied to more than 50% of patients, and in some cases without the consent of their legal representatives. On some occasions, restraints are used for attaining organizational or environmental objectives, such as complying with tight schedules, and for reducing or avoiding the supervision of patients who walk erratically and, at times, are used indefinitely. Even greater confusion exists with respect to the emerging concept of chemical or pharmacological restraints, since no conceptual framework exists based on scientific evidence, and with sufficient consensus for guiding healthcare workers. In this context, the Sociedad Española de Geriatría y Gerontología (SEGG--Spanish Geriatrics and Gerontology Society), aware of the significance and transcendence of the issue, and in an attempt to preserve and guarantee maximum freedom, dignity and self-esteem, on the one hand, and to ensure the maximum integrity and legal certainty of the persons cared for in geriatric and gerontology services and centers, on the other, decided to create an "Interdisciplinary Committee on Restraints" made up by members from different disciplines and members of SEGG Working Groups or Committees, external health care workers, groups

Attention Deficit Hyperactivity Disorder (ADHD) is the most common co-morbid condition encountered in people with tics and Tourette Syndrome (TS). The co-occurrence of TS and ADHD is associated with a higher psychopathological, social and academic impairment and the management may represent a challenge for the clinicians. To review recent advances in management of patients with tic, Tourette Syndrome and comorbid Attention Deficit Hyperactivity Disorder. We searched peer reviewed and original medical publications (PUBMED 1990-2012) and included randomized, double-blind, controlled trials related to pharmacological treatment for tic and TS used in children and adolescents with comorbid ADHD. "Tourette Syndrome" or "Tic" and "ADHD", were cross referenced with the words "pharmacological treatment", "α-agonist", "psychostimulants", "selective norepinephrine reuptake inhibitor", "antipsychotics". Three classes of drugs are currently used in the treatment of TS and comorbid ADHD: α-agonists (clonidine and guanfacine), stimulants (amphetamine enantiomers, methylphenidate enantiomers or slow release preparation), and selective norepinephrine reuptake inhibitor (atomoxetine). It has been recently suggested that in a few selected cases partial dopamine agonists (aripiprazole) could be useful. Level A of evidence supported the use of noradrenergic agents (clonidine). Reuptake inhibitors (atomoxetine) and stimulants (methylphenidate) could be, also used for the treatment of TS and comorbid ADHD. Taking into account the risk-benefit profile, clonidine could be used as the first line treatment. However only few studies meet rigorous quality criteria in terms of study design and methodology; most trials have low statistical power due to small sample size or short duration. Treatment should be "symptom targeted" and personalized for each patient. Copyright © 2013 European Paediatric Neurology Society. Published by Elsevier Ltd. All rights reserved.

When love hurts. A systematic review on the effects of surgical and pharmacological treatments for endometriosis on female sexual functioning.

Endometriosis is associated with an increased risk of dyspareunia, therefore this chronic gynecologic disease should be considered as a major cause of sexual dysfunctions. The aims of this study were to review the literature on the effects of surgical and pharmacological treatments for endometriosis on female sexual functioning, and to provide suggestions for future treatment strategies. We followed the PRISMA guidelines to conduct this systematic review, which involved an electronic database search of studies on the association between endometriosis and sexuality published between 2000 and 2016. As a result of the screening process, 22 studies were included in this systematic review. The 22 studies included were divided into two categories: (a) surgical intervention studies (n = 17), examining postoperative sexual outcomes of surgery for endometriosis; (b) pharmacological intervention studies (n = 5), evaluating the effects of pharmacological endometriosis treatments on sexual functioning. The studies considered showed that overall surgical and pharmacological interventions for endometriosis can lead to medium-/long-term improvement, but not necessarily to a definitive resolution of female sexual dysfunctions due to endometriosis. Sexual functioning is a multidimensional phenomenon and the ideal treatment for endometriosis-related sexual dysfunctions should be conducted by a multidisciplinary team that involves not only gynecologists, but also sexologists and psychologists/psychotherapists. Improving global sexual functioning, and not just reducing pain at intercourse, should be considered as a major clinical goal of endometriosis treatment. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

2017-04-01

The study of botulinum neurotoxins (BoNT) is rapidly progressing in many aspects. Novel BoNTs are being discovered owing to next generation sequencing, but their biologic and pharmacological properties remain largely unknown. The molecular structure of the large protein complexes that the toxin forms with accessory proteins, which are included in some BoNT type A1 and B1 pharmacological preparations, have been determined. By far the largest effort has been dedicated to the testing and validation of BoNTs as therapeutic agents in an ever increasing number of applications, including pain therapy. BoNT type A1 has been also exploited in a variety of cosmetic treatments, alone or in combination with other agents, and this specific market has reached the size of the one dedicated to the treatment of medical syndromes. The pharmacological properties and mode of action of BoNTs have shed light on general principles of neuronal transport and protein-protein interactions and are stimulating basic science studies. Moreover, the wide array of BoNTs discovered and to be discovered and the production of recombinant BoNTs endowed with specific properties suggest novel uses in therapeutics with increasing disease/symptom specifity. These recent developments are reviewed here to provide an updated picture of the biologic mechanism of action of BoNTs, of their increasing use in pharmacology and in cosmetics, and of their toxicology.

Phage Therapy: Eco-Physiological Pharmacology

Directory of Open Access Journals (Sweden)

Stephen T. Abedon

2014-01-01

Full Text Available Bacterial virus use as antibacterial agents, in the guise of what is commonly known as phage therapy, is an inherently physiological, ecological, and also pharmacological process. Physiologically we can consider metabolic properties of phage infections of bacteria and variation in those properties as a function of preexisting bacterial states. In addition, there are patient responses to pathogenesis, patient responses to phage infections of pathogens, and also patient responses to phage virions alone. Ecologically, we can consider phage propagation, densities, distribution (within bodies, impact on body-associated microbiota (as ecological communities, and modification of the functioning of body “ecosystems” more generally. These ecological and physiological components in many ways represent different perspectives on otherwise equivalent phenomena. Comparable to drugs, one also can view phages during phage therapy in pharmacological terms. The relatively unique status of phages within the context of phage therapy as essentially replicating antimicrobials can therefore result in a confluence of perspectives, many of which can be useful towards gaining a better mechanistic appreciation of phage therapy, as I consider here. Pharmacology more generally may be viewed as a discipline that lies at an interface between organism-associated phenomena, as considered by physiology, and environmental interactions as considered by ecology.

Pharmacological enhancement of treatment for amblyopia

Rashad, Mohammad A

2012-01-01

Background The purpose of this study was to compare a weight-adjusted dose of carbidopa- levodopa as treatment adjunctive to occlusion therapy with occlusion therapy alone in children and adults with different types of amblyopia. Methods This prospective study included 63 patients with amblyopia classified into two groups, ie, an occlusion group which included 35 patients who received occlusion therapy only and a pharmacological enhancement group which included 28 patients who received oral carbidopa-levodopa together with occlusion therapy for 6 weeks. Results The mean logarithm of the minimal angle of resolution (logMAR) of the eyes with amblyopia was not significantly different in the occlusion group (0.52, 0.52, and 0.51) than in the pharmacological enhancement group (0.58, 0.49, and 0.56) at three follow-up visits (at months 1, 3, and 12, respectively). There was a highly significant improvement in mean logMAR of amblyopic eyes compared with baseline in both occlusion groups (from 0.68 to 0.52, from 0.68 to 0.52, and from 0.68 to 0.51) and in the pharmacological enhancement group (from 0.81 to 0.58, from 0.81 to 0.49, and from 0.81 to 0.56) at the month 1, 3, and 12 visits (P = 0.01, P = 0.01, and P = 0.001, respectively). The improvement of mean logMAR in the subgroup of patients older than 12 years was greater in the pharmacological enhancement group (42.5%) than in the occlusion group (30%). The improvement of mean logMAR in the subgroup of patients with severe amblyopia was greater in the pharmacological enhancement group (34.3%) than in the occlusion group (22%). Conclusion Significant improvement was reported in both groups at all follow-up visits over 1 year. Regardless of the etiology of amblyopia, levodopa-carbidopa may be added to part-time occlusion in older patients as a means of increasing the plasticity of the visual cortex. Levodopa may add to the effect of occlusion in severe amblyopia and bilateral amblyopia. PMID:22536029

AIMS Given the reported high rates of medication errors, especially in elderly patients, we hypothesized that current curricula do not devote enough time to the teaching of geriatric pharmacology. This review explores the quantity and nature of geriatric pharmacology education in undergraduate and postgraduate curricula for health professionals. METHODS Pubmed, Embase and PsycINFO databases were searched (from 1 January 2000 to 11 January 2011), using the terms ‘pharmacology’ and ‘education’ in combination. Articles describing content or evaluation of pharmacology education for health professionals were included. Education in general and geriatric pharmacology was compared. RESULTS Articles on general pharmacology education (252) and geriatric pharmacology education (39) were included. The number of publications on education in general pharmacology, but not geriatric pharmacology, has increased over the last 10 years. Articles on undergraduate and postgraduate education for 12 different health disciplines were identified. A median of 24 h (from 15 min to 4956 h) devoted to pharmacology education and 2 h (1–935 h) devoted to geriatric pharmacology were reported. Of the articles on education in geriatric pharmacology, 61.5% evaluated the teaching provided, mostly student satisfaction with the course. The strength of findings was low. Similar educational interventions were not identified, and evaluation studies were not replicated. CONCLUSIONS Recently, interest in pharmacology education has increased, possibly because of the high rate of medication errors and the recognized importance of evidence-based medical education. Nevertheless, courses on geriatric pharmacology have not been evaluated thoroughly and none can be recommended for use in training programmes. Suggestions for improvements in education in general and geriatric pharmacology are given. PMID:22416832

Systems Pharmacology in Small Molecular Drug Discovery

Directory of Open Access Journals (Sweden)

Wei Zhou

2016-02-01

Full Text Available Drug discovery is a risky, costly and time-consuming process depending on multidisciplinary methods to create safe and effective medicines. Although considerable progress has been made by high-throughput screening methods in drug design, the cost of developing contemporary approved drugs did not match that in the past decade. The major reason is the late-stage clinical failures in Phases II and III because of the complicated interactions between drug-specific, human body and environmental aspects affecting the safety and efficacy of a drug. There is a growing hope that systems-level consideration may provide a new perspective to overcome such current difficulties of drug discovery and development. The systems pharmacology method emerged as a holistic approach and has attracted more and more attention recently. The applications of systems pharmacology not only provide the pharmacodynamic evaluation and target identification of drug molecules, but also give a systems-level of understanding the interaction mechanism between drugs and complex disease. Therefore, the present review is an attempt to introduce how holistic systems pharmacology that integrated in silico ADME/T (i.e., absorption, distribution, metabolism, excretion and toxicity, target fishing and network pharmacology facilitates the discovery of small molecular drugs at the system level.

Low prevalence of hypertension with pharmacological treatments and associated factors

Helena Gama

2013-06-01

Full Text Available OBJECTIVE: To assess the determinants of the lack of pharmacological treatment for hypertension. METHODS: In 2005, 3,323 Mozambicans aged 25-64 years old were evaluated. Blood pressure, weight, height and smoking status were assessed following the Stepwise Approach to Chronic Disease Risk Factor Surveillance. Hypertensives (systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg and/or antihypertensive drug therapy were evaluated for awareness of their condition, pharmacological and non-pharmacological management, as well as use of herbal or traditional remedies. Prevalence ratios (PR were calculated, adjusted for sociodemographic characteristics, cardiovascular risk factors and non-pharmacological treatment. RESULTS: Most of the hypertensive subjects (92.3%, and nearly half of those aware of their condition were not treated pharmacologically. Among the aware, the prevalence of untreated hypertension was higher in men {PR = 1.61; 95% confidence interval (95%CI 1.10;2.36} and was lower in subjects under non-pharmacological treatment (PR = 0.58; 95%CI 0.42;0.79; there was no significant association with traditional treatments (PR = 0.75; 95%CI 0.44;1.26. CONCLUSIONS: The lack of pharmacological treatment for hypertension was more frequent in men, and was not influenced by the presence of other cardiovascular risk factors; it could not be explained by the use of alternative treatments as herbal/traditional medicines or non-pharmacological management. It is important to understand the reasons behind the lack of management of diagnosed hypertension and to implement appropriate corrective actions to reduce the gap in the access to healthcare between developed and developing countries.

Sauer, Kristin; Kemper, Claudia; Glaeske, Gerd

2011-01-01

Fibromyalgia syndrome (FMS) is a chronic pain condition impacting on quality of life, causing physical and psychological impairment resulting in limited participation in professional and social life. The objective of this study was to assess the prevalence, recommended pharmacological and non-pharmacological interventions of FMS, patients' characteristics and to compare findings to current research. About 1.6 Mio patients of a German statutory health insurance company (GEK) in 2007 were analyzed for: (a) the prevalence of FMS (ICD-10: M79.7); (b) and comorbid depression (ICD-10: F32/33); (c) the recommended pharmacological and non-pharmacological intervention rates; (d) and characteristics of patients associated with being prescribed recommended interventions. The (a) standardized prevalence of FMS in 2007 was 0.05% in men and 0.4% in women. (b) 51.9% of the patients with prevalent FMS had a comorbid depression in 2007 (88.2% female). (c) 66% of FMS patients received the recommended pharmacological treatment, 59% physical therapy, 6.1% cognitive-behavioural therapy and 3.4% a combination of these (multi-component therapy, MCT). (d) One year increase in age was associated with a 3% decrease in the predicted odds of receiving MCT (95%, CI 0.95-0.99). The current data indicate an FMS-prevalence that differs from epidemiological surveys and screenings, probably due to methodological differences. Especially females with comorbid depression are affected. The likelihood of receiving MCT is not associated with gender, but with younger age. Yet, the findings seem to indicate insufficient and inadequate treatment, but FMS warrants more research. Copyright © 2010 Société française de rhumatologie. Published by Elsevier SAS.

Schizophrenia is a severe mental disorder and many patients are treated in primary care settings. Apart from the pharmacological management of disease-associated symptoms, the detection and treatment of side effects is of the utmost importance in clinical practice. The purpose of this publication is to offer relevant evidence-based recommendations for the biological treatment of schizophrenia in primary care. This publication is a short and practice-oriented summary of Parts I-III of the World Federation of Societies of Biological Psychiatry (WFSBP) Guidelines for Biological Treatment of Schizophrenia. The recommendations were developed by the authors and consented by a task force of international experts. Guideline recommendations are based on randomized-controlled trials and supplemented with non-randomized trials and meta-analyses where necessary. Antipsychotics of different chemical classes are the first-line pharmacological treatments for schizophrenia. Specific circumstances (e.g., suicidality, depression, substance dependence) may need additional treatment options. The pharmacological and non-pharmacological management of side effects is of crucial importance for the long-term treatment in all settings of the healthcare system. This summary of the three available evidence-based guidelines has the potential to support clinical decisions and can improve treatment of schizophrenia in primary care settings.

2013-04-01

Veterinary therapeutics, based on the art of Materia Medica, has been practised for countless centuries, but the science of veterinary pharmacology is of very recent origin. This review traces the contribution of Materia Medica to veterinary therapeutics from the Egyptian period through to the Age of Enlightenment. The first tentative steps in the development of the science of veterinary pharmacology were taken in the 18th century, but it was not until the mid 20th century that the science replaced the art of Materia Medica. This review traces the 20th century developments in veterinary pharmacology, with emphasis on the explosion of knowledge in the 35 year period to 2010. The range of factors which have influenced the current status of the discipline are reviewed. Future developments are considered from the perspectives of what might be regarded as desirable and those innovations that might be anticipated. We end with words of encouragement for young colleagues intent upon pursuing a career in veterinary pharmacology. © 2013 Blackwell Publishing Ltd.

2018-01-01

Individuals with schizophrenia lead a poor quality of life, due to poor medical attention, homelessness, unemployment, financial constraints, lack of education, and poor social skills. Thus, a review of factors associated with the holistic management of schizophrenia is of paramount importance. The objective of this review is to improve the quality of life of individuals with schizophrenia, by addressing the factors related to the needs of the patients and present them in a unified manner. Although medications play a role, other factors that lead to a successful holistic management of schizophrenia include addressing the following: financial management, independent community living, independent living skill, relationship, friendship, entertainment, regular exercise for weight gained due to medication administration, co-morbid health issues, and day-care programmes for independent living. This review discusses the relationship between different symptoms and problems individuals with schizophrenia face (e.g., homelessness and unemployment), and how these can be managed using pharmacological and non-pharmacological methods. Thus, the target of this review is the carers of individuals with schizophrenia, public health managers, counselors, case workers, psychiatrists, and clinical psychologists aiming to enhance the quality of life of individuals with schizophrenia.

Targeting Adenosine Signaling in Parkinson's Disease: From Pharmacological to Non-pharmacological Approaches

Luiza R. Nazario

2017-11-01

Full Text Available Parkinson's disease (PD is one of the most prevalent neurodegenerative disease displaying negative impacts on both the health and social ability of patients and considerable economical costs. The classical anti-parkinsonian drugs based in dopaminergic replacement are the standard treatment, but several motor side effects emerge during long-term use. This mini-review presents the rationale to several efforts from pre-clinical and clinical studies using adenosine receptor antagonists as a non-dopaminergic therapy. As several studies have indicated that the monotherapy with adenosine receptor antagonists reaches limited efficacy, the usage as a co-adjuvant appeared to be a promising strategy. The formulation of multi-targeted drugs, using adenosine receptor antagonists and other neurotransmitter systems than the dopaminergic one as targets, have been receiving attention since Parkinson's disease presents a complex biological impact. While pharmacological approaches to cure or ameliorate the conditions of PD are the leading strategy in this area, emerging positive aspects have arisen from non-pharmacological approaches and adenosine function inhibition appears to improve both strategies.

Pharmacological and non-pharmacological treatment options for depression and depressive symptoms in hemodialysis patients

Directory of Open Access Journals (Sweden)

Stefania S. Grigoriou

2015-04-01

Full Text Available Depression is a mental disorder with a high prevalence among patients with end stage renal disease (ESRD. It is reported that depression afflicts approximately 20-30% of this patient population, being associated, amongst other, with high mortality rate, low adherence to medication and low perceived quality of life. There is a variety of medications known to be effective for the treatment of depression but due to poor adherence to treatment as well as due to the high need for medications addressing other ESRD comorbidities, depression often remains untreated. According to the literature, depression is under-diagnosed and undertreated in the majority of the patients with chronic kidney disease. In the current review the main pharmacological and non-pharmacological approaches and research outcomes for the management of depressive symptoms in hemodialysis patients are discussed.

Pharmacological Conversion of a Cardiac Inward Rectifier into an Outward Rectifier Potassium Channel.

Science.gov (United States)

Moreno-Galindo, Eloy G; Sanchez-Chapula, Jose A; Tristani-Firouzi, Martin; Navarro-Polanco, Ricardo A

2016-09-01

Potassium (K(+)) channels are crucial for determining the shape, duration, and frequency of action-potential firing in excitable cells. Broadly speaking, K(+) channels can be classified based on whether their macroscopic current outwardly or inwardly rectifies, whereby rectification refers to a change in conductance with voltage. Outwardly rectifying K(+) channels conduct greater current at depolarized membrane potentials, whereas inward rectifier channels conduct greater current at hyperpolarized membrane potentials. Under most circumstances, outward currents through inwardly rectifying K(+) channels are reduced at more depolarized potentials. However, the acetylcholine-gated K(+) channel (KACh) conducts current that inwardly rectifies when activated by some ligands (such as acetylcholine), and yet conducts current that outwardly rectifies when activated by other ligands (for example, pilocarpine and choline). The perplexing and paradoxical behavior of KACh channels is due to the intrinsic voltage sensitivity of the receptor that activates KACh channels, the M2 muscarinic receptor (M2R). Emerging evidence reveals that the affinity of M2R for distinct ligands varies in a voltage-dependent and ligand-specific manner. These intrinsic receptor properties determine whether current conducted by KACh channels inwardly or outwardly rectifies. This review summarizes the most recent concepts regarding the intrinsic voltage sensitivity of muscarinic receptors and the consequences of this intriguing behavior on cardiac physiology and pharmacology of KACh channels.

Radioreceptor assay: theory and applications to pharmacology

International Nuclear Information System (INIS)

Perret, G.; Simon, P.

1984-01-01

The aim of the first part of this work is to present the theory of the radioreceptor assay and to compare it to the other techniques of radioanalysis (radioimmunoassay, competitive protein binding assays). The technology of the radioreceptor assay is then presented and its components (preparation of the receptors, radioligand, incubation medium) are described. The analytical characteristics of the radioreceptor assay (specificity, sensitivity, reproductibility, accuracy) and the pharmacological significance of the results are discussed. The second part is devoted to the description of the radioreceptor assays of some pharmacological classes (neuroleptics, tricyclic antidepressants, benzodiazepines, β-blockers, anticholinergic drugs) and to their use in therapeutic drug monitoring. In conclusion, by their nature, radioreceptor assays are highly sensitive, reliable, precise, accurate and simple to perform. Their chief disadvantage relates to specificity, since any substance having an appreciable affinity to the receptor site will displace the specifically bound radioligand. Paradoxically in some cases, this lack of specificity may be advantageous in that it allows for the detection of not only the apparent compound but of active metabolites and endogenous receptor agonists as well and in that radioreceptors assays can be devised for a whole pharmacological class and not only for one drug as it is the case for classical physico-chemical techniques. For all these reasons future of radioreceptor assay in pharmacology appears promising [fr

2016-03-01

Cardiac glycosides are an important cause of poisoning, reflecting their widespread clinical usage and presence in natural sources. Poisoning can manifest as varying degrees of toxicity. Predominant clinical features include gastrointestinal signs, bradycardia and heart block. Death occurs from ventricular fibrillation or tachycardia. A wide range of treatments have been used, the more common including activated charcoal, atropine, β-adrenoceptor agonists, temporary pacing, anti-digoxin Fab and magnesium, and more novel agents include fructose-1,6-diphosphate (clinical trial in progress) and anticalin. However, even in the case of those treatments that have been in use for decades, there is debate regarding their efficacy, the indications and dosage that optimizes outcomes. This contributes to variability in use across the world. Another factor influencing usage is access. Barriers to access include the requirement for transfer to a specialized centre (for example, to receive temporary pacing) or financial resources (for example, anti-digoxin Fab in resource poor countries). Recent data suggest that existing methods for calculating the dose of anti-digoxin Fab in digoxin poisoning overstate the dose required, and that its efficacy may be minimal in patients with chronic digoxin poisoning. Cheaper and effective medicines are required, in particular for the treatment of yellow oleander poisoning which is problematic in resource poor countries. © 2015 The British Pharmacological Society.

There was a highly significant improvement in mean logMAR of amblyopic eyes compared with baseline in both occlusion groups (from 0.68 to 0.52, from 0.68 to 0.52, and from 0.68 to 0.51 and in the pharmacological enhancement group (from 0.81 to 0.58, from 0.81 to 0.49, and from 0.81 to 0.56 at the month 1, 3, and 12 visits (P = 0.01, P = 0.01, and P = 0.001, respectively. The improvement of mean logMAR in the subgroup of patients older than 12 years was greater in the pharmacological enhancement group (42.5% than in the occlusion group (30%. The improvement of mean logMAR in the subgroup of patients with severe amblyopia was greater in the pharmacological enhancement group (34.3% than in the occlusion group (22%.Conclusion: Significant improvement was reported in both groups at all follow-up visits over 1 year. Regardless of the etiology of amblyopia, levodopa-carbidopa may be added to part-time occlusion in older patients as a means of increasing the plasticity of the visual cortex. Levodopa may add

The incidence of community-acquired pneumonia complications has increased during the last decade. According to the records from several countries, empyema and necrotizing pneumonia became more frequent during the last few years. The optimal therapeutic approach for such conditions is still controversial. Both pharmacological management (antimicrobials and fibrinolysis), and surgical management (pleural drainage and video-assisted thoracoscopic surgery), are the subject of continuous assessment. In this paper, the Spanish Society of Paediatric Infectious Diseases and the Spanish Society of Paediatric Chest Diseases have reviewed the available evidence. Consensus treatment guidelines are proposed for complications of community-acquired pneumonia in children, focusing on parapneumonic pleural effusion. Recommendations are also provided for the increasing population of patients with underlying diseases and immunosuppression. Copyright © 2014 Asociación Española de Pediatría.

The use of systematic approach for the analysis of mechanism of action of drugs at different levels of biological organization of organisms is an important task in experimental and clinical pharmacology for drug designing and increasing the efficacy and safety of drugs. The analysis of published data on pharmacological effects of psychotropic drugs possessing immunomodulatory and/or antiviral properties have shown a correlation between central effects of examined drugs associated with the impact on the processes of neurogenesis of adult brain and survival of neurons, and their ability to alter levels of key proinflammatory cytokines. The changes that occur as a result of the influence of pharmacological agents at one of the systems should inevitably lead to the functional reorganization at another. Integrative mechanisms underlying the neuro-immune interactions may explain the "pleiotropic" pharmacological effects of some antiviral and immunomodulatory drugs. Amantadine, which was originally considered as an antiviral agent, was approved as anti-parkinsonic drug after its wide medical use. The prolonged administration of interferon alpha caused depression in 30-45% of patients, thus limiting its clinical use. The antiviral drug "Oseltamivir" may provoke the development of central side effects, including abnormal behavior, delirium, impaired perception and suicides. Anti-herpethetical drug "Panavir" shows pronounced neuroprotective properties. The purpose of this review is to analyze the experimental and clinical data related to central effects of drugs with antiviral or/and immunotropic activity, and to discover the relationship of these effects with changes in reactivity of immune system and proinflammatory response.

Pharmacological Effects of Biotin in Animals.

Riveron-Negrete, Leticia; Fernandez-Mejia, Cristina

2017-01-01

In recent decades, it was found that vitamins affect biological functions in ways other than their long-known functions; niacin is the best example of a water-soluble vitamin known to possess multiple actions. Biotin, also known as vitamin B7 or vitamin H, is a water-soluble B-complex vitamin that serves as a covalently-bound coenzyme of carboxylases. It is now well documented that biotin has actions other than participating in classical enzyme catalysis reactions. Several lines of evidence have demonstrated that pharmacological concentrations of biotin affect glucose and lipid metabolism, hypertension, reproduction, development, and immunity. The effect of biotin on these functions is related to its actions at the transcriptional, translational, and post-translational levels. The bestsupported mechanism involved in the genetic effects of biotin is the soluble guanylate cyclase/protein kinase G (PKG) signaling cascade. Although there are commercially-available products containing pharmacological concentrations of biotin, the toxic effects of biotin have been poorly studied. This review summarizes the known actions and molecular mechanisms of pharmacological doses of biotin in animals and current information regarding biotin toxicity.

Manual therapies are generally requested by patients with tension type headache. To compare the efficacy of multimodal manual therapy vs. pharmacological care for the management of tension type headache pain by conducting a meta-analysis of randomized controlled trials. PubMed, MEDLINE, EMBASE, AMED, CINAHL, EBSCO, Cochrane Database of Systematic Reviews, Cochrane Collaboration Trials Register, PEDro and SCOPUS were searched from their inception until June 2014. All randomized controlled trials comparing any manual therapy vs. medication care for treating tension type headache adults were included. Data were extracted and methodological quality assessed independently by two reviewers. We pooled headache frequency as the main outcome and also intensity and duration. The weighted mean difference between manual therapy and pharmacological care was used to determine effect sizes. Five randomized controlled trials met our inclusion criteria and were included in the meta-analysis. Pooled analyses found that manual therapies were more effective than pharmacological care in reducing frequency (weighted mean difference -0.8036, 95% confidence interval -1.66 to -0.44; three trials), intensity (weighted mean difference -0.5974, 95% confidence interval -0.8875 to -0.3073; five trials) and duration (weighted mean difference -0.5558, 95% confidence interval -0.9124 to -0.1992; three trials) of the headache immediately after treatment. No differences were found at longer follow-up for headache intensity (weighted mean difference -0.3498, 95% confidence interval -1.106 to 0.407; three trials). Manual therapies were associated with moderate effectiveness at short term, but similar effectiveness at longer follow-up for reducing headache frequency, intensity and duration in tension type headache than pharmacological medical drug care. However, due to the heterogeneity of the interventions, these results should be considered with caution at this stage. © International Headache

2014-07-01

Full Text Available Abstract: Objective: To identify the pharmacologic interactions of oral anti-cancer drugs provided at an outpatient clinic. Material and methods: Anti-cancer drugs included in the Phamacotherapeutic Guideline of the Hospital were identified. A literature search was carried out on the pharmacologic interactions in MEDLINE® and EMBASE® (with the filer language English or Spanish, and the descriptors: “name of the anti-cancer drug” AND (“drug interactions” OR “pharmacokinetic”, Up-to-date®, MICROMEDEX® and the drug information sheet for the EMA and the FDA. Information was also gathered from the abstract presented to European and Spanish scientific meetings for the last 4 years. When an interaction was analyzed and had clinical relevance, the best pharmacotherapeutic interaction-free alternative was sought. Results: Twenty-three drugs were identified, of which Chlorambucil, Fludarabine, Lenalidomide, Melphalan, and Thalidomide were the active compounds with the lowest likelihood of producing a pharmacologic interaction. Tyrosine kinase inhibitors (particularly Erlotinib, Imatinib, Lapatinib, and Pazopanib are the drugs with highest number of pharmacologic interactions described, many of them with severe clinical consequences, with increases and decreases of the plasma levels of anti-cancer drugs. The active compounds identified that may have pharmacologic interactions with anticancer drugs were mainly: Allopurinol, Amiodarone, Carbamazepine, Dabigatran, Digoxin, Spironolactone, Phenytoin, Itraconazol, Repaglinide, Silodosin, Tamoxifen, Verapamil, and Warfarin. Pharmacologic interactions through the cytochrome P450 1A2, 2D6, 2C8, 2C9, 3A4 were the most important for tyrosine kinase inhibitors. Other non-pharmacologic compounds, with an important potential of producing relevant pharmacologic interaction were immunomodulators (Echinacea extracts and Hypericum perforatum. Conclusions: Oral anticancer drugs have numerous pharmacologic

Pharmacological hypothesis: Nitric oxide-induced inhibition of ADAM-17 activity as well as vesicle release can in turn prevent the production of soluble endothelin-converting enzyme.

Endothelin-1 (ET-1) and nitric oxide (NO) are two highly potent vasoactive molecules with opposing effects on the vasculature. Endothelin-converting enzyme (ECE) and nitric oxide synthase (NOS) catalyse the production of ET-1 and NO, respectively. It is well established that these molecules play a crucial role in the initiation and progression of cardiovascular diseases and have therefore become targets of therapy. Many studies have examined the mechanism(s) by which NO regulates ET-1 production. Expression and localization of ECE-1 is a key factor that determines the rate of ET-1 production. ECE-1 can either be membrane bound or be released from the cell surface to produce a soluble form. NO has been shown to reduce the expression of both membrane-bound and soluble ECE-1. Several studies have examined the mechanism(s) behind NO-mediated inhibition of ECE expression on the cell membrane. However, the precise mechanism(s) behind NO-mediated inhibition of soluble ECE production are unknown. We hypothesize that both exogenous and endogenous NO, inhibits the production of soluble ECE-1 by preventing its release via extracellular vesicles (e.g., exosomes), and/or by inhibiting the activity of A Disintegrin and Metalloprotease-17 (ADAM17). If this hypothesis is proven correct in future studies, these pathways represent targets for the therapeutic manipulation of soluble ECE-1 production. © 2017 The Authors.

Force-platform analysis was performed and a "symmetry index" for peak vertical force (PVF was calculated. Owners completed LOAD, CBPI and HCPI instruments. As a test of construct validity, inter-instrument correlations were calculated. As a test of criterion validity, the correlations between instrument scores and PVF symmetry scores were calculated. Additionally, internal consistency of all instruments was calculated and compared to those previously reported. Factor analysis is reported for the first time for LOAD, and is compared to that previously reported for CBPI and HCPI.Significant moderate correlations were found between all instruments, implying construct validity for all instruments. Significant weak correlations were found between LOAD scores and PVF symmetry index, and between CBPI scores and PVF symmetry index.LOAD is an owner-completed clinical metrology instrument that can be recommended for the measurement of canine osteoarthritis. It is convenient to use, validated and, as demonstrated here for the first time, has a correlation with force-platform data.

Pharmacological Treatment for Atrial Fibrillation

Full Text Available Pharmacological treatment for atrial fibrillation has a variety of purposes, such as pharmacological defibrillation, maintenance of sinus rhythm, heart rate control to prevent congestive heart failure and prevention of both cerebral infarction and atrial remodeling. Sodium channel blockers are superior to potassium channel blockers for atrial defibrillation, while both sodium and potassium channel blockers are effective in the maintenance of sinus rhythm. In general, digitalis or Ca antagonists are used to control heart rate during atrial fibrillation to prevent congestive heart failure, while amiodarone or bepridil also reduce heart rates during atrial fibrillation. Anticoagulant therapy with warfarin is recommended to prevent cerebral infarction and angiotensin converting enzyme antagonists or angiotensin II receptor blockers are also used to prevent atrial remodeling. One should select appropriate drugs for treatment of atrial fibrillation according to the patient's condition.

At present, no treatment recommendations can be made for compulsive buying disorder. Recent studies have found evidence for the efficacy of psychotherapeutic options, but less is known regarding the best pharmacologic treatment. The purpose of this review is to present and analyze the available published evidence on the pharmacological treatment of compulsive buying disorder. To achieve this, we conducted a review of studies focusing on the pharmacological treatment of compulsive buying by searching the PubMed/MEDLINE database. Selection criteria were applied, and 21 studies were identified. Pharmacological classes reported included antidepressants, mood stabilizers, opioid antagonists, second-generation antipsychotics, and N-methyl-D-aspartate receptor antagonists. We found only placebo-controlled trials for fluvoxamine; none showed effectiveness against placebo. Three open-label trials reported clinical improvement with citalopram; one was followed by a double-blind discontinuation. Escitalopram was effective in an open-label trial but did not show efficacy in the double-blind phase. Memantine was identified as effective in a pilot open-label study. Fluoxetine, bupropion, nortriptyline, clomipramine, topiramate and naltrexone were only reported to be effective in clinical cases. According to the available literature, there is no evidence to propose a specific pharmacologic agent for compulsive buying disorder. Future research is required for a better understanding of both pathogenesis and treatment of this disorder.

Hung, Hsuan-Man; Chiang, Hsiao-Ching

2017-02-01

Most women experience the worse sleep quality of their life during pregnancy and the early postpartum period. Although pregnancy typically accounts for a relatively short part of a woman's life, the related sleep disturbances may have a significant and negative impact on her long-term health. Approximately 78-80% of pregnant women experience sleep disturbances, including interruptions in deep sleep, decreased total sleep time, poor subjective sleep quality, frequent night waking, and reduced sleep efficacy. Sleep disturbances during pregnancy start during the first trimester and become prevalent during the third trimester. Related factors include physiological and psychosocial changes and an unhealthy lifestyle. As non-pharmacological interventions have the potential to improve sleep quality in 70% to 80% of patients with insomnia, this is the main approached that is currently used to treat pregnancy-related sleep disturbances. Examples of these non-pharmacological interventions include music therapy, aerobic exercise, massage, progressive muscle relaxation, multi-modal interventions, and the use of a maternity support belt. The efficacy and safety of other related non-pharmacological interventions such as auricular acupressure, cognitive therapy, tai chi, and aromatherapy remain uncertain, with more empirical research required. Additionally, non-pharmacological interventions do not effectively treat sleep disturbances in all pregnant women.

Rehmannia glutinosa, a widely used traditional Chinese herb, belongs to the family of Scrophulariaceae, and is taken to nourish Yin and invigorate the kidney in traditional Chinese medicine (TCM) and has a very high medicinal value. In recent decades, a great number of chemical and pharmacological studies have been done on Rehmannia glutinosa. More than 70 compounds including iridoids, saccharides, amino acid, inorganic ions, as well as other trace elements have been found in the herb. Studies show that Rehmannia glutinosa and its active principles possess wide pharmacological actions on the blood system, immune system, endocrine system, cardiovascular system and the nervous system. Currently, the effective monomeric compounds or active parts have been screened for the pharmacological activity of Rehmannia glutinosa and the highest quality scientific data is delivered to support the further application and exploitation for new drug development.

2017-11-01

To investigate the pharmacological mechanism of Guizhi Fuling Wan (GFW) in the treatment of uterine fibroids, a network pharmacology approach was used. Information on GFW compounds was collected from traditional Chinese medicine (TCM) databases, and input into PharmMapper to identify the compound targets. Genes associated with uterine fibroids genes were then obtained from the GeneCards and Online Mendelian Inheritance in Man databases. The interaction data of the targets and other human proteins was also collected from the STRING and IntAct databases. The target data were input into the Database for Annotation, Visualization and Integrated Discovery for gene ontology (GO) and pathway enrichment analyses. Networks of the above information were constructed and analyzed using Cytoscape. The following networks were compiled: A compound-compound target network of GFW; a herb-compound target-uterine fibroids target network of GWF; and a compound target-uterine fibroids target-other human proteins protein-protein interaction network, which were subjected to GO and pathway enrichment analyses. According to this approach, a number of novel signaling pathways and biological processes underlying the effects of GFW on uterine fibroids were identified, including the negative regulation of smooth muscle cell proliferation, apoptosis, and the Ras, wingless-type, epidermal growth factor and insulin-like growth factor-1 signaling pathways. This network pharmacology approach may aid the systematical study of herbal formulae and make TCM drug discovery more predictable.

Fibromyalgia is characterized by widespread pain, sleep problems, fatigue, functional impairment, psychological distress, and cognitive dysfunction. The objective of this meta-analysis is to synthesize the available data on the effectiveness of pharmacological and non-pharmacological interventions across all domains included in the Outcome Measures in Rheumatology Clinical Trials (OMERACT-10) fibromyalgia response definitions, and to examine response based on these definitions. We searched Cochrane, PubMed, Scopus, and the reference lists of articles for randomized controlled trials of any drug formulation or non-pharmacological intervention used for fibromyalgia treatment. We extracted efficacy data regarding pain, sleep, physical function, fatigue, anxiety, depression, and cognition. The available data were insufficient to draw definite conclusions regarding response. Indirect evidence indicates that it may be expected with the use of serotonin noradrenaline reuptake inhibitors (SNRIs), noradrenaline reuptake inhibitors (NRIs), and multidisciplinary treatment.

As part of the Basic Science Survey Series (BSSS) for Dentistry, members of the American Dental Education Association (ADEA) Physiology, Pharmacology, and Therapeutics Section surveyed course directors of basic pharmacology courses in North American dental schools. The survey was designed to assess, among other things, faculty affiliation and experience of course directors, teaching methods, general course content and emphasis, extent of interdisciplinary (shared) instruction, and impact of recent curricular changes. Responses were received from forty-nine of sixty-seven (73.1 percent) U.S. and Canadian dental schools. The findings suggest the following: 1) substantial variation exists in instructional hours, faculty affiliation, placement within curriculum, class size, and interdisciplinary nature of pharmacology courses; 2) pharmacology course content emphasis is similar among schools; 3) the number of contact hours in pharmacology has remained stable over the past three decades; 4) recent curricular changes were often directed towards enhancing the integrative and clinically relevant aspects of pharmacology instruction; and 5) a trend toward innovative content delivery, such as use of computer-assisted instruction applications, is evident. Data, derived from this study, may be useful to pharmacology course directors, curriculum committees, and other dental educators with an interest in integrative and interprofessional education.

People with severe mental illness (SMI) have reduced life expectancy compared with the general population, which can be explained partly by their increased risk of diabetes. We conducted a meta-analysis to determine the clinical effectiveness of pharmacological and non-pharmacological interventions for improving glycaemic control in people with SMI (PROSPERO registration: CRD42015015558). A systematic literature search was performed on 30/10/2015 to identify randomised controlled trials (RCTs) in adults with SMI, with or without a diagnosis of diabetes that measured fasting blood glucose or glycated haemoglobin (HbA1c). Screening and data extraction were carried out independently by two reviewers. We used random effects meta-analysis to estimate effectiveness, and subgroup analysis and univariate meta-regression to explore heterogeneity. The Cochrane Collaboration’s tool was used to assess risk of bias. We found 54 eligible RCTs in 4,392 adults (40 pharmacological, 13 behavioural, one mixed intervention). Data for meta-analysis were available from 48 RCTs (n = 4052). Both pharmacological (mean difference (MD), -0.11mmol/L; 95% confidence interval (CI), [-0.19, -0.02], p = 0.02, n = 2536) and behavioural interventions (MD, -0.28mmol//L; 95% CI, [-0.43, -0.12], pfasting glucose, but not HbA1c (pharmacological MD, -0.03%; 95% CI, [-0.12, 0.06], p = 0.52, n = 1515; behavioural MD, 0.18%; 95% CI, [-0.07, 0.42], p = 0.16, n = 140) compared with usual care or placebo. In subgroup analysis of pharmacological interventions, metformin and antipsychotic switching strategies improved HbA1c. Behavioural interventions of longer duration and those including repeated physical activity had greater effects on fasting glucose than those without these characteristics. Baseline levels of fasting glucose explained some of the heterogeneity in behavioural interventions but not in pharmacological interventions. Although the strength of the evidence is limited by inadequate trial design

2017-01-01

Binge-eating disorder (BED) is the most common eating disorder and is associated with poor physical and mental health outcomes. Psychological and behavioral interventions have been a mainstay of treatment for BED, but as understanding of this disorder has grown, pharmacologic agents have become promising treatment options for some patients. At this time, only one drug-the stimulant prodrug lisdexamfetamine-is approved for the treatment of BED. Numerous classes of medications including antidepressants, anticonvulsants, and antiobesity drugs have been explored as off-label treatments for BED with variable success. Although not all patients with BED may be suitable candidates for pharmacotherapy, all patients should be considered for and educated about pharmacologic treatment options. © Copyright 2017 Physicians Postgraduate Press, Inc.

It is common for men to develop erectile dysfunction after radical prostatectomy. The anatomy of the rat allows the cavernous nerve (CN) to be identified, dissected, and injured in a controlled fashion. Therefore, bilateral CN injury (BCNI) in the rat model is routinely used to study post-prostatectomy erectile dysfunction. To compare and contrast the available literature on pharmacologic intervention after BCNI in the rat. A literature search was performed on PubMed for cavernous nerve and injury and erectile dysfunction and rat. Only articles with BCNI and pharmacologic intervention that could be grouped into categories of immune modulation, growth factor therapy, receptor kinase inhibition, phosphodiesterase type 5 inhibition, and anti-inflammatory and antifibrotic interventions were included. To assess outcomes of pharmaceutical intervention on erectile function recovery after BCNI in the rat model. The ratio of maximum intracavernous pressure to mean arterial pressure was the main outcome measure chosen for this analysis. All interventions improved erectile function recovery after BCNI based on the ratio of maximum intracavernous pressure to mean arterial pressure results. Additional end-point analysis examined the corpus cavernosa and/or the major pelvic ganglion and CN. There was extreme heterogeneity within the literature, making accurate comparisons between crush injury and therapeutic interventions difficult. BCNI in the rat is the accepted animal model used to study nerve-sparing post-prostatectomy erectile dysfunction. However, an important limitation is extreme variability. Efforts should be made to decrease this variability and increase the translational utility toward clinical trials in humans. Haney NM, Nguyen HMT, Honda M, et al.

2018-02-01

Full Text Available Major advances in therapeutic proteins, including antibody–drug conjugates (ADCs, have created revolutionary drug delivery systems in cancer over the past decade. While these immunoconjugate agents provide several advantages compared to their small-molecule counterparts, their clinical use is still in its infancy. The considerations in their development and clinical use are complex, and consist of multiple components and variables that can affect the pharmacologic characteristics. It is critical to understand the mechanisms employed by ADCs in navigating biological barriers and how these factors affect their biodistribution, delivery to tumors, efficacy, and toxicity. Thus, future studies are warranted to better understand the complex pharmacology and interaction between ADC carriers and biological systems, such as the mononuclear phagocyte system (MPS and tumor microenvironment. This review provides an overview of factors that affect the pharmacologic profiles of ADC therapies that are currently in clinical use and development.

Cannabis Pharmacology: The Usual Suspects and a Few Promising Leads.

Science.gov (United States)

Russo, Ethan B; Marcu, Jahan

2017-01-01

The golden age of cannabis pharmacology began in the 1960s as Raphael Mechoulam and his colleagues in Israel isolated and synthesized cannabidiol, tetrahydrocannabinol, and other phytocannabinoids. Initially, THC garnered most research interest with sporadic attention to cannabidiol, which has only rekindled in the last 15 years through a demonstration of its remarkably versatile pharmacology and synergy with THC. Gradually a cognizance of the potential of other phytocannabinoids has developed. Contemporaneous assessment of cannabis pharmacology must be even far more inclusive. Medical and recreational consumers alike have long believed in unique attributes of certain cannabis chemovars despite their similarity in cannabinoid profiles. This has focused additional research on the pharmacological contributions of mono- and sesquiterpenoids to the effects of cannabis flower preparations. Investigation reveals these aromatic compounds to contribute modulatory and therapeutic roles in the cannabis entourage far beyond expectations considering their modest concentrations in the plant. Synergistic relationships of the terpenoids to cannabinoids will be highlighted and include many complementary roles to boost therapeutic efficacy in treatment of pain, psychiatric disorders, cancer, and numerous other areas. Additional parts of the cannabis plant provide a wide and distinct variety of other compounds of pharmacological interest, including the triterpenoid friedelin from the roots, canniprene from the fan leaves, cannabisin from seed coats, and cannflavin A from seed sprouts. This chapter will explore the unique attributes of these agents and demonstrate how cannabis may yet fulfil its potential as Mechoulam's professed "pharmacological treasure trove." © 2017 Elsevier Inc.

In Germany, depending on a sexual offender's culpability and the severity of the offence, he/she can be placed either in the forensic-psychiatric or the correctional system. Numbers related to the pharmacological treatment of sexual offenders for the correctional system are missing so far. In sexual offenders, the pharmacological treatment of paraphilic disorders is of special importance. The present study aimed at assessing the prevalence of pharmacological sexual offender treatment in German outpatient treatment centers supervising mainly clients from the correctional sector. An online questionnaire was sent to 112 outpatient treatment centers and 21 provided data relevant for the present study. The included institutions reported about a total of 813 sexual offenders, of whom 200 (24.6%) were treated with pharmacological agents, most frequently antipsychotics (14.8%) and selective-serotonin-reuptake-inhibitors (7.1%). Of the total sample, 26.7% of sexual offenders were diagnosed with a paraphilic - mainly with a pedophilic - disorder. Only 2% were treated with androgen-deprivation therapy. Compared with forensic-psychiatric institutions, only a minority of sexual offenders are treated with medication specifically addressing paraphilic symptomatology. However, the prevalence of paraphilic disorders found in the present study suggests that pharmacological treatment of paraphilic fantasies and behaviors could be of great importance in the correctional sector as well.

The Pharmacologic and Clinical Effects of Illicit Synthetic Cannabinoids.

White, C Michael

2017-03-01

This article presents information on illicitly used synthetic cannabinoids. Synthetic cannabinoids are structurally heterogeneous and commonly used drugs of abuse that act as full agonists of the cannabinoid type-1 receptor but have a variety of additional pharmacologic effects. There are numerous cases of patient harm and death in the United States, Europe, and Australia with many psychological, neurological, cardiovascular, pulmonary, and renal adverse events. Although most users prefer using cannabis, there are convenience, legal, and cost reasons driving the utilization of synthetic cannabinoids. Clinicians should be aware of pharmacologic and clinical similarities and differences between synthetic cannabinoid and cannabis use, the limited ability to detect synthetic cannabinoids in the urine or serum, and guidance to treat adverse events. © 2016, The American College of Clinical Pharmacology.

A subset of potassium channels is regulated primarily by changes in the cytoplasmic concentration of ions, including calcium, sodium, chloride, and protons. The eight members of this subfamily were originally all designated as calcium-activated channels. More recent studies have clarified the gating mechanisms for these channels and have documented that not all members are sensitive to calcium. This article describes the molecular relationships between these channels and provides an introduction to their functional properties. It also introduces a new nomenclature that differentiates between calcium- and sodium-activated potassium channels.

research organizations. This movement has created the opportunity for the safety pharmacology discipline to come "full circle" and return to the drug discovery arena (target identification through clinical candidate selection) to contribute to the mitigation of the high rate of candidate drug failure through better compound selection decision making. Finally, the changing focus of science and losses in didactic training of scientists in whole animal physiology and pharmacology have revealed a serious gap in the future availability of qualified individuals to apply the principles of safety pharmacology in support of drug discovery and development. This is a significant deficiency that at present is only partially met with academic and professional society programs advancing a minimal level of training. In summary, with the exception that the future availability of suitably trained scientists is a critical need for the field that remains to be effectively addressed, the prospects for the future of safety pharmacology are hopeful and promising, and challenging for those individuals who want to assume this responsibility. What began in the early part of the new millennium as a relatively simple model of testing to assure the safety of Phase I clinical subjects and patients from acute deleterious effects on life-supporting organ systems has grown with experience and time to a science that mobilizes the principles of cellular and molecular biology and attempts to predict acute adverse events and those associated with long-term treatment. These challenges call for scientists with a broad range of in-depth scientific knowledge and an ability to adapt to a dynamic and forever changing industry. Identifying individuals who will serve today and training those who will serve in the future will fall to all of us who are committed to this important field of science.

Pharmacological ascorbate and ionizing radiation (IR increase labile iron in pancreatic cancer

Directory of Open Access Journals (Sweden)

Justin C. Moser

2014-01-01

Full Text Available Labile iron, i.e. iron that is weakly bound and is relatively unrestricted in its redox activity, has been implicated in both the pathogenesis as well as treatment of cancer. Two cancer treatments where labile iron may contribute to their mechanism of action are pharmacological ascorbate and ionizing radiation (IR. Pharmacological ascorbate has been shown to have tumor-specific toxic effects due to the formation of hydrogen peroxide. By catalyzing the oxidation of ascorbate, labile iron can enhance the rate of formation of hydrogen peroxide; labile iron can also react with hydrogen peroxide. Here we have investigated the magnitude of the labile iron pool in tumor and normal tissue. We also examined the ability of pharmacological ascorbate and IR to change the size of the labile iron pool. Although a significant amount of labile iron was seen in tumors (MIA PaCa-2 cells in athymic nude mice, higher levels were seen in murine tissues that were not susceptible to pharmacological ascorbate. Pharmacological ascorbate and irradiation were shown to increase the labile iron in tumor homogenates from this murine model of pancreatic cancer. As both IR and pharmacological ascorbate may rely on labile iron for their effects on tumor tissues, our data suggest that pharmacological ascorbate could be used as a radio-sensitizing agent for some radio-resistant tumors.

Little is known about ethnic, cultural and socioeconomic differences in childhood ownership and attitudes to pets. The objective of this study was to describe the factors associated with living with different pet types, as well as factors that may influence the intensity of relationship or 'attachment' that children have to their pet. Data were collected using a survey of 1021 9-10 year old primary school children in a deprived area of the city of Liverpool, UK. Dogs were the most common pet owned, most common 'favourite' pet, and species most attached to. Twenty-seven percent of dog-owning children (10% of all children surveyed) reported living with a 'Bull Breed' dog (which includes Pit Bulls and Staffordshire Bull Terriers), and the most popular dog breed owned was the Staffordshire Bull Terrier. Multivariable regression modelling identified a number of variables associated with ownership of different pets and the strength of attachment to the child's favourite pet. Girls were more likely to own most pet types, but were no more or less attached to their favourite pet than boys. Children of white ethnicity were more likely to own dogs, rodents and 'other' pets but were no more or less attached to their pets than children of non-white ethnicity. Single and youngest children were no more or less likely to own pets than those with younger brothers and sisters, but they showed greater attachment to their pets. Children that owned dogs lived in more deprived areas than those without dogs, and deprivation increased with number of dogs owned. 'Pit Bull or cross' and 'Bull Breed' dogs were more likely to be found in more deprived areas than other dog types. Non-whites were also more likely to report owning a 'Pit Bull or cross' than Whites. Gender, ethnicity and socioeconomic status were associated with pet ownership, and sibling status with level of attachment to the pet. These are important to consider when conducting research into the health benefits and risks of the

Fraxinus , a member of the Oleaceae family, commonly known as ash tree is found in northeast Asia, north America, east and western France, China, northern areas of Pakistan, India, and Afghanistan. Chemical constituents of Fraxinus plant include various secoiridoids, phenylethanoids, flavonoids, coumarins, and lignans; therefore, it is considered as a plant with versatile biological and pharmacological activities. Its tremendous range of pharmacotherapeutic properties has been well documented including anticancer, anti-inflammatory, antioxidant, antimicrobial, and neuroprotective. In addition, its bioactive phytochemicals and secondary metabolites can be effectively used in cosmetic industry and as a competent antiaging agent. Fraxinus presents pharmacological effectiveness by targeting the novel targets in several pathological conditions, which provide a spacious therapeutic time window. Our aim is to update the scientific research community with recent endeavors with specifically highlighting the mechanism of action in different diseases. This potentially efficacious pharmacological drug candidate should be used for new drug discovery in future. This review suggests that this plant has extremely important medicinal utilization but further supporting studies and scientific experimentations are mandatory to determine its specific intracellular targets and site of action to completely figure out its pharmacological applications.

Pharmacological and non- pharmacological treatment of hypertension: A review article

Marjan Seyedmazhari

2013-01-01

Full Text Available BACKGROUND: Hypertension is a worldwide epidemic disease. It is more common and more severe in elderly persons. Various studies however have estimated 41.9 million men and 27.8 million women to have prehypertension. Diagnosis and early treatment of prehypertension are of utmost importance. Although hypertension is usually divided into 2 general categories of essential (primary and secondary hypertension, the initial treatment for hypertension often depends on its stage which is determined by systolic and diastolic blood pressure. Lifestyle modification is the first step in treating stage one hypertension. Pharmaceutical treatments including diuretics, angiotensin converting enzyme (ACE inhibitors, calcium blockers, beta blockers, and angiotensin receptor blockers will be recommended if lifestyle modification fails to control blood pressure.    METHODS: The PubMed database was searched by a number of keywords including hypertension, pharmaceutical treatment, and non-pharmaceutical treatment. The results were limited by determining a date range of 2008-11.    RESULTS: High blood pressure causes major health problems for many people around the world. It should be controlled because of its high mortality and morbidity. However, in order to select an appropriate treatment modality, it is initially important to diagnose the kinds and stages of hypertension. Pharmaceutical or non-pharmaceutical treatments can then be employed to control this serious disease.    CONCLUSION: Treating hypertension depends on the kinds and stages of this disease. Several tips should be considered when selecting a method of treatment.       Keywords: Hypertension, Pharmacological treatment, Non-pharmacological treatment

The aim of the study was to assess schizotypy by using the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE), in the groups of patients with schizophrenia, bipolar disorder (BD) and unipolar (recurrent) depression (UD). An important element of the study was to compare - in terms of similarity - the results obtained in schizophrenia and BD, and - in terms of differences - the results obtained in BD and UD. The study involved 58 patients with schizophrenia (35 men, 23 women, mean age = 34.0, SD = 9.8), 52 patients with BD (22 men, 30 women, mean age = 40.3, SD = 13.6) and 57 UD patients (24 men, 33 women, mean age = 50.2, SD = 11.9), treated in the Department of Adult Psychiatry, Poznan University of Medical Sciences. For the assessment of schizotypy, the full version of the O-LIFE questionnaire (104 questions) was used, including such dimensions as: unusual experiences, cognitive disorganization, introvertive anhedonia and impulsive nonconformity. The biggest differences between diagnostic groups were found in the dimensions of unusual experiences and impulsive nonconformity. Similarities between schizophrenia and BD were found for unusual experiences, cognitive disorganization and introvertive anhedonia. Differences between BD and UD were obtained for unusual experiences and impulsive nonconformity. The assessment of schizotypy in three diagnostic groups (it was the first study in patients with UD), allowed to address contemporary pathogenic and clinical concepts pertaining to similarities between schizophrenia and BD as well as to differences between two types of affective disorders.

André Russowsky Brunoni

Full Text Available BACKGROUND: Although meta-analyses have shown that placebo responses are large in Major Depressive Disorder (MDD trials; the placebo response of devices such as repetitive transcranial magnetic stimulation (rTMS has not been systematically assessed. We proposed to assess placebo responses in two categories of MDD trials: pharmacological (antidepressant drugs and non-pharmacological (device- rTMS trials. METHODOLOGY/PRINCIPAL FINDINGS: We performed a systematic review and meta-analysis of the literature from April 2002 to April 2008, searching MEDLINE, Cochrane, Scielo and CRISP electronic databases and reference lists from retrieved studies and conference abstracts. We used the keywords placebo and depression and escitalopram for pharmacological studies; and transcranial magnetic stimulation and depression and sham for non-pharmacological studies. All randomized, double-blinded, placebo-controlled, parallel articles on major depressive disorder were included. Forty-one studies met our inclusion criteria - 29 in the rTMS arm and 12 in the escitalopram arm. We extracted the mean and standard values of depression scores in the placebo group of each study. Then, we calculated the pooled effect size for escitalopram and rTMS arm separately, using Cohen's d as the measure of effect size. We found that placebo response are large for both escitalopram (Cohen's d - random-effects model - 1.48; 95%C.I. 1.26 to 1.6 and rTMS studies (0.82; 95%C.I. 0.63 to 1. Exploratory analyses show that sham response is associated with refractoriness and with the use of rTMS as an add-on therapy, but not with age, gender and sham method utilized. CONCLUSIONS/SIGNIFICANCE: We confirmed that placebo response in MDD is large regardless of the intervention and is associated with depression refractoriness and treatment combination (add-on rTMS studies. The magnitude of the placebo response seems to be related with study population and study design rather than the intervention

MELAS (mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes) is a mitochondrial disease most usually caused by point mutations in tRNA genes encoded by mitochondrial DNA (mtDNA). Approximately 80% of cases of MELAS syndrome are associated with a m.3243A > G mutation in the MT-TL1 gene, which encodes the mitochondrial tRNALeu (UUR). Currently, no effective treatments are available for this chronic progressive disorder. Treatment strategies in MELAS and other mitochondrial diseases consist of several drugs that diminish the deleterious effects of the abnormal respiratory chain function, reduce the presence of toxic agents or correct deficiencies in essential cofactors. We evaluated the effectiveness of some common pharmacological agents that have been utilized in the treatment of MELAS, in yeast, fibroblast and cybrid models of the disease. The yeast model harbouring the A14G mutation in the mitochondrial tRNALeu(UUR) gene, which is equivalent to the A3243G mutation in humans, was used in the initial screening. Next, the most effective drugs that were able to rescue the respiratory deficiency in MELAS yeast mutants were tested in fibroblasts and cybrid models of MELAS disease. According to our results, supplementation with riboflavin or coenzyme Q(10) effectively reversed the respiratory defect in MELAS yeast and improved the pathologic alterations in MELAS fibroblast and cybrid cell models. Our results indicate that cell models have great potential for screening and validating the effects of novel drug candidates for MELAS treatment and presumably also for other diseases with mitochondrial impairment. © 2012 The Authors.

Owning a pet dog could potentially improve child health through encouraging participation in physical activity, through dog walking. However, evidence to support this is limited and conflicting. In particular, little is known about children's participation in dog walking and factors that may be associated with this. The objective of this study was to describe the participation of children in dog walking, including their own and those belonging to somebody else, and investigate factors associated with regular walking with their own pet dog. Primary school children (n=1021, 9-10 years) from a deprived area of Liverpool were surveyed during a 'fitness fun day' as part of the SportsLinx project. The 'Child Lifestyle and Pets' survey included questions about pet ownership, pet attachment, and dog walking. Multivariable logistic regression models were used to investigate factors associated with walking any dog, or their own dog, several times a day or more, including level of attachment to the dog, dog type, and sociodemographic factors. Overall, 15.4% of children reported walking with any dog (their own or belonging to a friend or family member) ≥ once daily, 14.1% several times a week, 27.6% ≤ once a week, and 42.8% never. Dog owning children (37.1% of the population) more often reported dog walking 'several times a week or more' (OR=12.30, 95% CI=8.10-18.69, Ppet dogs may be an opportunity for increasing physical activity in 9-10 year old children. The identification of stronger attachment to dogs regularly walked is similar to findings in adult studies.

Lysergic acid diethylamide (LSD) was synthesized in 1938 and its psychoactive effects discovered in 1943. It was used during the 1950s and 1960s as an experimental drug in psychiatric research for producing so-called "experimental psychosis" by altering neurotransmitter system and in psychotherapeutic procedures ("psycholytic" and "psychedelic" therapy). From the mid 1960s, it became an illegal drug of abuse with widespread use that continues today. With the entry of new methods of research and better study oversight, scientific interest in LSD has resumed for brain research and experimental treatments. Due to the lack of any comprehensive review since the 1950s and the widely dispersed experimental literature, the present review focuses on all aspects of the pharmacology and psychopharmacology of LSD. A thorough search of the experimental literature regarding the pharmacology of LSD was performed and the extracted results are given in this review. (Psycho-) pharmacological research on LSD was extensive and produced nearly 10,000 scientific papers. The pharmacology of LSD is complex and its mechanisms of action are still not completely understood. LSD is physiologically well tolerated and psychological reactions can be controlled in a medically supervised setting, but complications may easily result from uncontrolled use by layman. Actually there is new interest in LSD as an experimental tool for elucidating neural mechanisms of (states of) consciousness and there are recently discovered treatment options with LSD in cluster headache and with the terminally ill.

Publications in Indian Journal of Pharmacology (IJP) are the face of contemporary pharmacology practices followed in health-care profession - a knowledge-based profession. It depicts trends in terms of quantity (proportions), quality, type (preclinical/clinical), thrust areas, etc., of pharmacology followed by biomedical community professions both nationally and internationally. This article aims to establish temporal trends in pharmacology research by pharmacy institutes in light of its publications to IJP from 2010 to 2015. The website of IJP was searched for publications year and issue wise for contributing authors from pharmacy institutions and analyzed for types of publications, their source and the categories of research documented in these publications. A total of 1034 articles were published, of which 189 (18%) articles were published by pharmacy institutes, of which 90% ( n = 170) were contributed from pharmacy institutes within India whereas 10% ( n = 19) from international pharmacy institutes. 75% of these were research publication, the majority of which (65%) were related to preclinical screening of phytochemical constituents from plants. With multi and interdisciplinary collaborations in pharmacy profession the trend needs to improve toward molecular and cellular pharmacology and clinical studies.

A modular interdisciplinary platform was developed to investigate the economic impact of oseltamivir treatment by dosage regimen under simulated influenza pandemic scenarios. The pharmacology module consisted of a pharmacokinetic distribution of oseltamivir carboxylate daily area under the concentration-time curve at steady state (simulated for 75 mg and 150 mg twice daily regimens for 5 days) and a pharmacodynamic distribution of viral shedding duration obtained from phase II influenza inoculation data. The epidemiological module comprised a susceptible, exposed, infected, recovered (SEIR) model to which drug effect on the basic reproductive number (R 0 ), a measure of transmissibility, was linked by reduction of viral shedding duration. The number of infected patients per population of 100 000 susceptible individuals was simulated for a series of pandemic scenarios, varying oseltamivir dose, R 0 (1.9 vs. 2.7), and drug uptake (25%, 50%, and 80%). The number of infected patients for each scenario was entered into the health economics module, a decision analytic model populated with branch probabilities, disease utility, costs of hospitalized patients developing complications, and case-fatality rates. Change in quality-adjusted life years was determined relative to base case. Oseltamivir 75 mg relative to no treatment reduced the median number of infected patients, increased change in quality-adjusted life years by deaths averted, and was cost-saving under all scenarios; 150 mg relative to 75 mg was not cost effective in low transmissibility scenarios but was cost saving in high transmissibility scenarios. This methodological study demonstrates proof of concept that the disciplines of pharmacology, disease epidemiology and health economics can be linked in a single quantitative framework. © 2017 The British Pharmacological Society.

Eating disorders, such as anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorders (BED), are described as abnormal eating habits that usually involve insufficient or excessive food intake. Animal models have been developed that provide insight into certain aspects of eating disorders. Several drugs have been found efficacious in these animal models and some of them have eventually proven useful in the treatment of eating disorders. This review will cover the role of monoaminergic neurotransmitters in eating disorders and their pharmacological manipulations in animal models and humans. Dopamine, 5-HT (serotonin) and noradrenaline in hypothalamic and striatal regions regulate food intake by affecting hunger and satiety and by affecting rewarding and motivational aspects of feeding. Reduced neurotransmission by dopamine, 5-HT and noradrenaline and compensatory changes, at least in dopamine D2 and 5-HT(2C/2A) receptors, have been related to the pathophysiology of AN in humans and animal models. Also, in disorders and animal models of BN and BED, monoaminergic neurotransmission is down-regulated but receptor level changes are different from those seen in AN. A hypofunctional dopamine system or overactive α2-adrenoceptors may contribute to an attenuated response to (palatable) food and result in hedonic binge eating. Evidence for the efficacy of monoaminergic treatments for AN is limited, while more support exists for the treatment of BN or BED with monoaminergic drugs. © 2014 The British Pharmacological Society.

Evolving paradigms in clinical pharmacology and therapeutics for the treatment of Duchenne muscular dystrophy.

Progressive muscle weakness and degeneration due to the lack of dystrophin eventually leads to the loss of independent ambulation by the middle of the patient's second decade, and a fatal outcome due to cardiac or respiratory failure by the third decade. More specifically, loss of sarcolemmal dystrophin and the dystrophin-associated glycoprotein (DAG) complex promotes muscle fiber damage during muscle contraction. This process results in an efflux of creatine kinase (CK), an influx of calcium ions, and the recruitment of T cells, macrophages, and mast cells to the damaged muscle, causing progressive myofiber necrosis. For the last 20 years, the major goal in the development of therapeutic approaches to alleviate muscle weakness in DMD has been centered on the restoration of dystrophin or proteins that are analogous to dystrophin, such as utrophin, through a variety of modalities including cell therapy, gene therapy, gene correction, and the highly promising techniques utilizing CRISPR/Cas9 technology. Despite the development of new therapeutic options, there still exist numerous challenges that we must face with regard to these new strategies and, consequently, we still do not have any feasible options available to ultimately slow the progression of this devastating disease. The purpose of this article is to highlight the current knowledge and advancements in the evolving paradigms in clinical pharmacology and therapeutics for this devastating musculoskeletal disease. © 2016 American Society for Clinical Pharmacology and Therapeutics.

The world wide web opens up new opportunities to interconnect electronic and classroom teaching and to promote active student participation. In this project article we describe the use of internet discussion forums as part of a student-centred teaching concept of pharmacology and discuss its advantages and disadvantages based on evaluation data and current literature. Final year medical students at the Technische Universität München (Munich, Germany) with the elective pharmacology moderated an internet forum that allowed all students to discuss pharmacology-related questions. Evaluation results of forum participants and elective students demonstrated a learning benefit of internet forums in pharmacology teaching. Internet discussion forums offer an easy-to-implement and effective way to actively engage students and increase the learning benefit of electronic and classroom teaching in pharmacology.

Jerde, Travis J.; Nakada, Stephen Y.

2007-04-01

Research in the field of ureteral physiology and pharmacology has traditionally been directed toward relaxation of ureteral spasm as a mechanism of analgesia during painful ureteral obstruction, most often stone-induced episodes. However, interest in this field has expanded greatly in recent years with the expanded use of alpha-blocker therapy for inducing stone passage, a usage now termed "medical expulsive therapy". While most clinical reports involving expulsive therapy have focused on alpha receptor or calcium channel blockade, there are diverse studies investigating pharmacological ureteral relaxation with novel agents including cyclooxygenase inhibitors, small molecule beta receptor agonists, neurokinin antagonists, and phosphodiesterase inhibitors. In addition, cutting edge molecular biology research is revealing promising potential therapeutic targets aimed at specific molecular changes that occur during the acute obstruction that accompanies stone disease. The purpose of this report is to review the use of pharmacological agents as ureteral smooth muscle relaxants clinically, and to look into the future of expulsive therapy by reviewing the available literature of ureteral physiology and pharmacology research.

During a two-year period a senior case-worker was seconded by a voluntary family case-work agency, the Liverpool Personal Service Society, to work with three general practitioners. The commonest reasons for referral of the 157 new patients to the social worker over this study period were extreme poverty; housing, matrimonial, and psychiatric problems; and problems of fatherless families. The successful and valuable co-operation between the general practitioners, case-worker, and various specialist professional and financial services of the Society have proved that a professional social worker has an important role in the general-practice team.

Recent developments in the behavioural and pharmacological enhancement of extinction of drug seeking.

Science.gov (United States)

Chesworth, Rose; Corbit, Laura H

2017-01-01

One of the principal barriers to overcoming addiction is the propensity to relapse, even after months or years of abstinence. Relapse can be precipitated by cues and contexts associated with drug use; thus, decreasing the conditioned properties of these cues and contexts may assist in preventing relapse. The predictive power of drug cues and contexts can be reduced by repeatedly presenting them in the absence of the drug reinforcer, a process known as extinction. The potential of extinction to limit relapse has generated considerable interest and research over the past few decades. While pre-clinical animal models suggest extinction learning assists relapse prevention, treatment efficacy is often lacking when extinction learning principles are translated into clinical trials. Conklin and Tiffany (Addiction, 2002) suggest the lack of efficacy in clinical practice may be due to limited translation of procedures demonstrated through animal research and propose several methodological improvements to enhance extinction learning for drug addiction. This review will examine recent advances in the behavioural and pharmacological manipulation of extinction learning, based on research from pre-clinical models. In addition, the translation of pre-clinical findings-both those suggested by Conklin and Tiffany () and novel demonstrations from the past 13 years-into clinical trials and the efficacy of these methods in reducing craving and relapse, where available, will be discussed. Finally, we highlight areas where promising pre-clinical models have not yet been integrated into current clinical practice but, if applied, could improve upon existing behavioural and pharmacological methods. © 2015 Society for the Study of Addiction.

Pharmacologic therapy for acute pancreatitis

2014-01-01

While conservative management such as fluid, bowel rest, and antibiotics is the mainstay of current acute pancreatitis management, there is a lot of promise in pharmacologic therapies that target various aspects of the pathogenesis of pancreatitis. Extensive review of preclinical studies, which include assessment of therapies such as anti-secretory agents, protease inhibitors, anti-inflammatory agents, and anti-oxidants are discussed. Many of these studies have shown therapeutic benefit and improved survival in experimental models. Based on available preclinical studies, we discuss potential novel targeted pharmacologic approaches that may offer promise in the treatment of acute pancreatitis. To date a variety of clinical studies have assessed the translational potential of animal model effective experimental therapies and have shown either failure or mixed results in human studies. Despite these discouraging clinical studies, there is a great clinical need and there exist several preclinical effective therapies that await investigation in patients. Better understanding of acute pancreatitis pathophysiology and lessons learned from past clinical studies are likely to offer a great foundation upon which to expand future therapies in acute pancreatitis.

Full Text Available Jonathan Pinkney1, Thomas Fox1, Lakshminarayan Ranganath21Department of Diabetes and Endocrinology, Peninsula College of Medicine and Dentistry, Plymouth, United Kingdom; 2Department of Clinical Biochemistry and Metabolic Medicine, Royal Liverpool University Hospital, Liverpool, United KingdomAbstract: Failure of secretion of the incretin hormone glucagon-like peptide-1 (GLP-1 plays a prominent role in type 2 diabetes, and restoration of GLP-1 action is an important therapeutic objective. Although the short duration of action of GLP-1 renders it unsuited to therapeutic use, 2 long-acting GLP-1 receptor agonists, exenatide and liraglutide, represent a significant advance in treatment. In controlled trials, both produce short-term glucose-lowering effects, with the reduction in hemoglobin A1c of up to 1.3%. These responses are often superior to those observed with additional oral agents. However, unlike sulfonylureas, thiazolidinediones, or insulin, all of which lead to significant weight gain, GLP-1 receptor agonists uniquely result in long-term weight loss of around 5 kg, and higher doses may enhance this further. Reduction in blood pressure of 2–7 mm Hg also has been observed. Both drugs produce transient mild gastrointestinal side effects; although mild hypoglycemia can occur, this is usually in combination with other hypoglycemic therapies. However, serious hypoglycemia and acute pancreatitis are rare. The once-daily dosage of liraglutide makes it more convenient than twice-daily dosage of prandial exenatide, and a superior glucose-lowering effect was observed in the only head-to-head comparison reported so far. Besides cost, these considerations currently favor liraglutide over exenatide. Further studies are needed to confirm long-term safety, and most importantly, that short-term benefits translate into long-term reductions of diabetes-related cardiovascular events and other complications.Keywords: diabetes, weight loss, glycemic control

Clinical Pharmacology of Chemotherapy Agents in Older People with Cancer

2011-01-01

Full Text Available Populations around the world are aging, and the associated increase in cancer incidence has led to the recognition of the importance of geriatric oncology. Chronological age is a poor determinant of pharmacological response to cancer chemotherapy agents. Age-associated changes in physiology and organ function have a significant impact on the clinical pharmacology of cancer chemotherapy agents used in cancer treatment. Altered response to medicines in older people is a consequence of changes in body composition, organ function, concomitant pathophysiology, multiple medications, genetic determinants of drug response, and patient's clinical status. These issues highlight the need to individualize the management of cancer in the older people with consideration of age-related changes in the clinical pharmacology of cancer drugs, analgesics, and adjunctive therapies.

Pain is a major stressor for critically ill patients. To maximize pain relief, non-pharmacological interventions are an interesting avenue to explore. The study aim was to describe the perspectives of patients/family members and nurses about the usefulness, relevance and feasibility of non-pharmacological interventions for pain management in the intensive care unit (ICU). A qualitative descriptive design was used. Patients/family members (n = 6) with a previous experience of ICU hospitalization and ICU nurses (n = 32) were recruited. Using a semi-structured discussion guide, participants were asked to share their perspective about non-pharmacological interventions that they found useful, relevant and feasible for pain management in the ICU. Interventions were clustered into five categories: a) cognitive-behavioural, b) physical, c) emotional support, d) helping with activities of daily living and, e) creating a comfortable environment. A total of eight focus groups (FGs) with patients/family members (two FGs) and ICU nurses (six FGs) were conducted. Overall, 33 non-pharmacological interventions were discussed. The top four non-pharmacological interventions found to be useful, relevant and feasible in at least half of the FGs were music therapy and distraction (cognitive-behavioural category), simple massage (physical category) and family presence facilitation (emotional support category). Interestingly, patients/family members and nurses showed different interests towards some interventions. For instance, patients discussed more about active listening/reality orientation, while nurses talked mostly about teaching/positioning. Four non-pharmacological interventions reached consensus in patients and nurses' FGs to be useful, relevant and feasible for pain management in the ICU. Other interventions seemed to be influenced by personal experience or professional role of the participants. While more evidence is required to conclude to their effectiveness, ICU nurses can

To evaluate the reporting of the statistical methods in articles published in two Indian pharmacology journals. All original articles published since 2002 were downloaded from the journals' (Indian Journal of Pharmacology (IJP) and Indian Journal of Physiology and Pharmacology (IJPP)) website. These articles were evaluated on the basis of appropriateness of descriptive statistics and inferential statistics. Descriptive statistics was evaluated on the basis of reporting of method of description and central tendencies. Inferential statistics was evaluated on the basis of fulfilling of assumption of statistical methods and appropriateness of statistical tests. Values are described as frequencies, percentage, and 95% confidence interval (CI) around the percentages. Inappropriate descriptive statistics was observed in 150 (78.1%, 95% CI 71.7-83.3%) articles. Most common reason for this inappropriate descriptive statistics was use of mean ± SEM at the place of "mean (SD)" or "mean ± SD." Most common statistical method used was one-way ANOVA (58.4%). Information regarding checking of assumption of statistical test was mentioned in only two articles. Inappropriate statistical test was observed in 61 (31.7%, 95% CI 25.6-38.6%) articles. Most common reason for inappropriate statistical test was the use of two group test for three or more groups. Articles published in two Indian pharmacology journals are not devoid of statistical errors.

Alternative pharmacological treatment options for agitation in Alzheimer’s disease

Francesco Panza

2015-11-01

Full Text Available In patients with dementia and Alzheimer’s disease (AD, treatment of neuropsychiatric symptoms (NPS is a major concern in the management of these devastating diseases. Among NPS in AD, agitation and aggression are common with earlier institutionalization, increased morbidity and mortality, and greater caregiver burden. Pharmacological treatments for AD-related agitation, specifically off-label use of atypical antipsychotics, showed only modest improvements, with increased side-effect burden and risk of mortality. Non-pharmacological treatment approaches have become the preferred firstline option. However, when such treatments fail, pharmacological options are often used. Therefore, there is an urgent need to identify effective and safe pharmacological treatments for agitation/aggression in AD and dementia. Unfortunately, progresses have been slow, with a small number of methodologically heterogeneous randomized controlled trials (RCTs, with disappointing results. However, evidence coming from recently completed RCTs on novel or repositioned drugs (mibampator, dextromethorphan/ quinidine, cannabinoids, and citalopram showed some promise in treating agitation in AD, but still with safety concerns. Further evidence will come from ongoing Phase II and III trials on promising novel drugs for treating these distressing symptoms in patients with AD and dementia.

Involuntary abnormal movements have been reported after ischaemic and haemorrhagic stroke. Post stroke movement disorders can appear as acute or delayed sequel. At the moment, for many of these disorders the knowledge of pharmacological treatment is still inadequate. Dopaminergic and GABAergic systems may be mainly involved in post-stroke movement disorders. This article provides a review on drugs commonly used in post-stroke movement disorders, given that some post-stroke movement disorders have shown a partial benefit with pharmacological approach.

The 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-lesioned primate is the gold-standard animal model of Parkinson disease (PD) and has been used to assess the effectiveness of experimental drugs on dyskinesia, parkinsonism, and psychosis. Three species have been used in most studies-the macaque, marmoset, and squirrel monkey-the last much less so than the first two species; however, the predictive value of each species at forecasting clinical efficacy, or lack thereof, is poorly documented. Here, we have reviewed all the published literature detailing pharmacologic studies that assessed the effects of experimental drugs on dyskinesia, parkinsonism, and psychosis in each of these species and have calculated their predictive value of success and failure at the clinical level. We found that, for dyskinesia, the macaque has a positive predictive value of 87.5% and a false-positive rate of 38.1%, whereas the marmoset has a positive predictive value of 76.9% and a false-positive rate of 15.6%. For parkinsonism, the macaque has a positive predictive value of 68.2% and a false-positive rate of 44.4%, whereas the marmoset has a positive predictive value of 86.9% and a false-positive rate of 41.7%. No drug that alleviates psychosis in the clinic has shown efficacy at doing so in the macaque, whereas the marmoset has 100% positive predictive value. The small number of studies conducted in the squirrel monkey precluded us from calculating its predictive efficacy. We hope our results will help in the design of pharmacologic experiments and will facilitate the drug discovery and development process in PD.

Pharmacologic stress testing for myocardial perfusion imaging is a widely used noninvasive method for the evaluation of known or suspected coronary artery disease. The use of exercise for cardiac stress has been practiced for over 60 years and clinicians are familiar with its using. However, there are inevitable situations in which exercise stress is inappropriate. A large number of patients with cardiac problems are unable to exercise to their full potential due to comorbidity such as osteoarthritis, vascular disease and pulmonary disease and a standard exercise stress test for myocardial perfusion imaging is suboptimal means for assessment of coronary artery disease. This problem has led to the development of the pharmacologic stress test and to a great increase in its popularity. All of the currently used pharmacologic agents have well-documented diagnostic value. This review deals the physiological actions, clinical protocols, safety, nuclear imaging applications of currently available stress agents and future development of new vasodilating agents

Pharmacological management of panic disorder

Carlo Marchesi

2008-03-01

Full Text Available Carlo MarchesiPsychiatric Section, Department of Neuroscience, University of Parma, Parma, ItalyAbstract: Panic disorder (PD is a disabling condition which appears in late adolescence or early adulthood and affects more frequently women than men. PD is frequently characterized by recurrences and sometimes by a chronic course and, therefore, most patients require longterm treatments to achieve remission, to prevent relapse and to reduce the risks associated with comorbidity. Pharmacotherapy is one of the most effective treatments of PD. In this paper, the pharmacological management of PD is reviewed. Many questions about this effective treatment need to be answered by the clinician and discussed with the patients to improve her/his collaboration to the treatment plan: which is the drug of choice; when does the drug become active; which is the effective dose; how to manage the side effects; how to manage nonresponse; and how long does the treatment last. Moreover, the clinical use of medication in women during pregnancy and breastfeeding or in children and adolescents was reviewed and its risk-benefit balance discussed.Keywords: panic disorder, pharmacological treatment, treatment guidelines

Summary Although substantial advances have been made in behavioral and pharmacological treatments for addictions, moving treatment development to the next stage may require novel ways of approaching addictions, particularly those derived from new findings regarding of the neurobiological underpinnings of addictions, while assimilating and incorporating relevant information from earlier approaches. In this review, we first briefly review theoretical and biological models of addiction and then describe existing behavioral and pharmacologic therapies for the addictions within this framework. We then propose new directions for treatment development and targets that are informed by recent evidence regarding the heterogeneity of addictions and the neurobiological contributions to these disorders.

With training in pharmacology, a pharmacologist has an expert knowledge as well as working experience in the subjects of therapeutics, pharmacokinetics, and toxicology along with exposure to subjects such as forensic medicine during the medical education. All these knowledge domains can be applied and act as an interface to the forensic situations. The skills and expertise of a forensic pharmacologist can be useful in a large and diverse number of legal cases. With an ever increasing incidence of criminal and civil cases in India, the development and inclusion of forensic pharmacologist in the judicial system of India are the need of the hour. The research in pharmacology has witnessed great technological advancement that allows it to expand its scope beyond the domain of therapeutics, thus enabling Indian pharmacologists to explore the niche area of Forensic Pharmacology. Differing pharmacokinetics and pharmacodynamics of drugs in living and dead, drug interactions, abuse of drugs, personal injury or death due to drug exposure leading to medico-legal issues, environmental exposure to chemicals, and doping and forensic pharmacovigilance are the diverse aspects of Forensic Pharmacology.

Label-free integrative pharmacology on-target of drugs at the β2-adrenergic receptor

Science.gov (United States)

Ferrie, Ann M.; Sun, Haiyan; Fang, Ye

2011-07-01

We describe a label-free integrative pharmacology on-target (iPOT) method to assess the pharmacology of drugs at the β2-adrenergic receptor. This method combines dynamic mass redistribution (DMR) assays using an array of probe molecule-hijacked cells with similarity analysis. The whole cell DMR assays track cell system-based, ligand-directed, and kinetics-dependent biased activities of the drugs, and translates their on-target pharmacology into numerical descriptors which are subject to similarity analysis. We demonstrate that the approach establishes an effective link between the label-free pharmacology and in vivo therapeutic indications of drugs.

Ginseng pharmacology: a new paradigm based on gintonin-lysophosphatidic acid receptor interactions

Directory of Open Access Journals (Sweden)

Seung-Yeol eNah

2015-10-01

Full Text Available Ginseng, the root of Panax ginseng, is used as a traditional medicine. Despite the long history of the use of ginseng, there is no specific scientific or clinical rationale for ginseng pharmacology besides its application as a general tonic. The ambiguous description of ginseng pharmacology might be due to the absence of a predominant active ingredient that represents ginseng pharmacology. Recent studies show that ginseng abundantly contains lysophosphatidic acids (LPAs, which are phospholipid-derived growth factor with diverse biological functions including those claimed to be exhibited by ginseng. LPAs in ginseng form a complex with ginseng proteins, which can bind and deliver LPA to its cognate receptors with a high affinity. As a first messenger, gintonin produces second messenger Ca2+ via G protein-coupled LPA receptors. Ca2+ is an intracellular mediator of gintonin and initiates a cascade of amplifications for further intercellular communications by activation of Ca2+-dependent kinases, receptors, gliotransmitter and neurotransmitter release. Ginsenosides, which have been regarded as primary ingredients of ginseng, cannot elicit intracellular [Ca2+]i transients, since they lack specific cell surface receptor. However, ginsenosides exhibit non-specific ion channel and receptor regulations. This is the key characteristic that distinguishes gintonin from ginsenosides. Although the current discourse on ginseng pharmacology is focused on ginsenosides, gintonin can definitely provide a mode of action for ginseng pharmacology that ginsenosides cannot. This review article introduces a novel concept of ginseng ligand-LPA receptor interaction and proposes to establish a paradigm that shifts the focus from ginsenosides to gintonin as a major ingredient representing ginseng pharmacology.

We report the results of administration of the Portuguese-Brazilian translation of the Liverpool Adverse Events Profile (LAEP) to 100 patients (mean age=34.5, SD=12.12; 56 females), 61 with symptomatic partial epilepsy (SPE) and 39 with idiopathic generalized epilepsy (IGE) (ILAE, 1989) who were on a stable antiepileptic drug (AED) regimen and being treated in a Brazilian tertiary epilepsy center. Carbamazepine was the most commonly used AED (43.0%), followed by valproic acid (32.0%). Two or more AEDs were used by 69.0% of patients. The mean LAEP score (19 questions) was 37.6 (SD=13.35). The most common adverse effects were sleepiness (35.0%), memory problems (35.0%), and difficulty in concentrating (25.0%). Higher LAEP scores were associated with polytherapy with three or more AEDs (P=0.005), female gender (P0.001) and Hospital Anxiety and Depression Scale (Depression: r=0.637, P<0.001; Anxiety: r=0.621, P<0.001) dimensions. LAEP overall scores were similar in people with SPE and IGE and were not helpful in differentiating adverse effects in these two groups. Clinical variables that influenced global LAEP were seizure frequency (P=0.050) and generalized tonic-clonic seizures in the last month (P=0.031) in the IGE group, and polytherapy with three or more AEDs (P=0.003 and P=0.003) in both IGE and SPE groups.

Intussusception is one of the most common causes of paediatric emergency. Fluoroscopy-guided hydrostatic reduction is a common nonoperative management strategy for the treatment of intussusception. The role of pharmacological premedication in increasing the success rate of hydrostatic reduction is still controversial. The purpose of this study was to verify the presence of a possible correlation between pharmacological premedication and the percentage of hydrostatic reduction of intussusception in paediatric patients. This study considered children with a diagnosis of idiopathic intussusception treated at our hospital between January 2007 and June 2013. One group of patients underwent hydrostatic reduction by barium enema without any preliminary therapy. A second group of patients received pharmacological premedication with both a sedative and an anti-oedematous agent before the procedure. A total of 398 patients were treated with barium enema for therapeutic purposes. In the group of patients who received no premedication (n = 254), 165 (65 %) children achieved hydrostatic reduction of the intussusception. Among the patients who received pharmacological premedication prior to barium enema (n = 144), 122 (85 %) children achieved resolution of the intussusception. Our study shows that the use of pharmacological premedication is effective for the reduction of the intussusception, as its limit patient stress, fluoroscopic time and radiation dose.

Naphthoquinone is a class of phenolic compounds derived from naphthalene. 7-Methyljuglone (7-MJ) is a naphthoquinone also known as ramentaceone or 6-Methyl-8-hydroxy-1,4-naphthoquinone or 5-Hydroxy-7-methyl-1,4-naphthoquinone or 7-Methyl-5-hydroxy-1,4-naphthoquinone or 5-Hydroxy-7-methyl-,1,4-naphtoquinone or 7-Methyl-5-hydroxynaphthalene-1,4-dione. This compound is a biologically active naphtoquinone, with a molecular weight of 188 g/mol mostly isolated in the genus Diospyros and Euclea. This review was aimed at providing available chemically and pharmacological data on 7-MJ. The chemical and pharmacological data were retrieved from the well-known scientific websites such as Pubmed, Google Scholar, Reaxys, Scirus, Scopus, Sciencedirect, Web-of-knowledge and Scifinder. 7-MJ was reported to have a variety of pharmacological activities such as antibacterial, antifungal, anticancer, antitubercular, anti-inflammatory and antiviral activities. The hemi-synthesis of the compound have been described. The present review pooled out together the knowledge on 7-MJ, and can serve as the start point for future research and valorization accomplishments.

Pharmacological therapy for analgesia and sedation in the newborn.

Science.gov (United States)

Anand, K J S; Hall, R W

2006-11-01

Rapid advances have been made in the use of pharmacological analgesia and sedation for newborns requiring neonatal intensive care. Practical considerations for the use of systemic analgesics (opioids, non-steroidal anti-inflammatory agents, other drugs), local and topical anaesthetics, and sedative or anaesthetic agents (benzodiazepines, barbiturates, other drugs) are summarised using an evidence-based medicine approach, while avoiding mention of the underlying basic physiology or pharmacology. These developments have inspired more humane approaches to neonatal intensive care. Despite these advances, little is known about the clinical effectiveness, immediate toxicity, effects on special patient populations, or long-term effects after neonatal exposure to analgesics or sedatives. The desired or adverse effects of drug combinations, interactions with non-pharmacological interventions or use for specific conditions also remain unknown. Despite the huge gaps in our knowledge, preliminary evidence for the use of neonatal analgesia and sedation is available, but must be combined with a clear definition of clinical goals, continuous physiological monitoring, evaluation of side effects or tolerance, and consideration of long-term clinical outcomes.

Amphetamine, past and present--a pharmacological and clinical perspective.

Heal, David J; Smith, Sharon L; Gosden, Jane; Nutt, David J

2013-06-01

Amphetamine was discovered over 100 years ago. Since then, it has transformed from a drug that was freely available without prescription as a panacea for a broad range of disorders into a highly restricted Controlled Drug with therapeutic applications restricted to attention deficit hyperactivity disorder (ADHD) and narcolepsy. This review describes the relationship between chemical structure and pharmacology of amphetamine and its congeners. Amphetamine's diverse pharmacological actions translate not only into therapeutic efficacy, but also into the production of adverse events and liability for recreational abuse. Accordingly, the balance of benefit/risk is the key challenge for its clinical use. The review charts advances in pharmaceutical development from the introduction of once-daily formulations of amphetamine through to lisdexamfetamine, which is the first d-amphetamine prodrug approved for the management of ADHD in children, adolescents and adults. The unusual metabolic route for lisdexamfetamine to deliver d-amphetamine makes an important contribution to its pharmacology. How lisdexamfetamine's distinctive pharmacokinetic/pharmacodynamic profile translates into sustained efficacy as a treatment for ADHD and its reduced potential for recreational abuse is also discussed.

Preemptive analgesia I: physiological pathways and pharmacological modalities.

LENUS (Irish Health Repository)

Kelly, D J

2012-02-03

PURPOSE: This two-part review summarizes the current knowledge of physiological mechanisms, pharmacological modalities and controversial issues surrounding preemptive analgesia. SOURCE: Articles from 1966 to present were obtained from the MEDLINE databases. Search terms included: analgesia, preemptive; neurotransmitters; pain, postoperative; hyperalgesia; sensitization, central nervous system; pathways, nociception; anesthetic techniques; analgesics, agents. Principal findings: The physiological basis of preemptive analgesia is complex and involves modification of the pain pathways. The pharmacological modalities available may modify the physiological responses at various levels. Effective preemptive analgesic techniques require multi-modal interception of nociceptive input, increasing threshold for nociception, and blocking or decreasing nociceptor receptor activation. Although the literature is controversial regarding the effectiveness of preemptive analgesia, some general recommendations can be helpful in guiding clinical care. Regional anesthesia induced prior to surgical trauma and continued well into the postoperative period is effective in attenuating peripheral and central sensitization. Pharmacologic agents such as NSAIDs (non-steroidal anti-inflammatory drugs) opioids, and NMDA (N-methyl-D-aspartate) - and alpha-2-receptor antagonists, especially when used in combination, act synergistically to decrease postoperative pain. CONCLUSION: The variable patient characteristics and timing of preemptive analgesia in relation to surgical noxious input requires individualization of the technique(s) chosen. Multi-modal analgesic techniques appear most effective.

Mesotherapy is the injection of active substances into the surface layer of the skin. This method allows a slower spread, higher levels, and longer lasting effects of drugs in the tissues underlying the site of injection (skin, muscle, and joint) compared with those following intramuscular injection. This technique is useful when a local pharmacological effect is required and relatively high doses of drug in the systemic circulation are not. Mesotherapy should only be undertaken following a complete clinical workup and subsequent diagnosis. Encouraging results have been reported in randomized, controlled clinical trials and in observational studies involving patients with various forms of musculoskeletal pain. Recommendations by experts from the Italian Society of Mesotherapy for appropriate use of mesotherapy in musculoskeletal pain and an algorithm for treating localized painful conditions are provided.

Learning of medical pharmacology via innovation:a personal experience at McMaster and in Asia

Institute of Scientific and Technical Information of China (English)

Chiu-yin KWAN

2004-01-01

Pharmacology in the traditional medical curriculum has been treated as a discrete "preclinical" discipline identifying itself distinctly different from the other preclinical sciences or clinical subjects in knowledge base as well as learning/teaching instructions. It is usually run in series with other pre-clinical courses (eg, anatomy, biochemistry,physiology etc), but in parallel with other paraclinical courses such as pathology, microbiology and community medicine. Clinical pharmacology was only introduced relatively recently designed to overcome the perceived deficiency in "preclinical" pharmacology regarding its therapeutic relevance and application to medicine. In many universities, both preclinical and clinical pharmacology courses co-exist, usually independently offered by two separate, sometimes non-interacting Departments of Pharmacology and Clinical Pharmacology. In this model,pharmacology is generally taught in a teacher-centered, discipline-oriented, and knowledge-based curriculum.Furthermore, pharmacology courses are commonly taught by "expert" teachers, who usually engage in excessiveteaching, often adopt a knowledge-based approach in both instruction and assessment, and frequently evade or ignore clinical relevance. The clinical relevance of the pharmacological sciences is sometimes also taught in a didactic and problem-solving manner, although it is usually case-oriented. In recent years, problem-based medical curricula have emerged, in varying forms, as a platform in which pharmacology is viewed as an integrated component in a holistic approach to medical education. In this problem-based learning (PBL) model, pharmacology is learned in a student-centered environment, based on self-directed, clinically relevant and case-oriented approach,usually in a small-group tutorial format. In PBL, pharmacology is learned in concert with other subject issues relevant to the case-problem in question, such as anatomy, physiology, pathology, microbiology

Pharmacological and Non-pharmacological Therapies of Cognitive Impairment in Multiple Sclerosis.

Science.gov (United States)

Miller, Elzbieta; Morel, Agnieszka; Redlicka, Justyna; Miller, Igor; Saluk, Joanna

2018-01-01

Cognitive impairment is one of the most important clinical features of neurodegenerative disorders including multiple sclerosis (MS). Conducted research shows that up to 65 percent of MS patients have cognitive deficits such as episodic memory, sustained attention, reduced verbal fluency; however, the cognitive MS domain is information processing speed. It is the first syndrome of cognitive dysfunction and the most widely affected in MS. Occasionally these impairments occur even before the appearance of physical symptoms. Therefore, this review focused on the current status of our knowledge about possible methods of treatment cognitive impairment in MS patients including novel strategies. Research and online content was performed using Medline and EMBASE databases. The most recent research suggests that cognitive impairment is correlated with brain lesion volume and brain atrophy. The examination of the cognitive impairment is usually based on particular neuropsychological batteries. However, it can be not enough to make a precise diagnosis. This creates a demand to find markers that might be useful for identifying patients with risk of cognitive impairment at an early stage of the disease. Currently the most promising methods consist of neuroimaging indicators, such as diffusion tensor imaging, the magnetization transfer ratio, and N-acetyl aspartate levels. Diagnosis problems are strictly connected with treatment procedures. There are two main cognitive therapies: pharmacological (disease modifying drugs (DMD), symptomatic treatments) and non-pharmacological interventions that are focused on psychological and physical rehabilitation. Some trials have shown a positive association between physical activity and the cognitive function. This article is an overview of the current state of knowledge related to cognition impairment treatment in MS. Additionally, novel strategies for cognitive impairments such as cryostimulation and other complementary methods are

The first part of this review describes the physiological basis of BOLD fMRI and the hemodynamic response on which the MRI contrast is based. Specific emphasis goes to possible effects of anaesthesia and the animal’s physiological conditions on neural activity and the hemodynamic response. The second part of this review describes applications of the aforementioned techniques in pharmacologically-induced, as well as in traumatic and transgenic disease models and illustrates how multiple fMRI methods can be applied successfully to evaluate different aspects of a specific disorder. For example, fMRI techniques can be used to pinpoint the neural substrate of a disease beyond previously defined hypothesis-driven regions-of-interest (ROIs. In addition, fMRI techniques allow one to dissect how specific modifications (e.g. treatment, lesion etc. modulate the functioning of specific brain areas (st-fMRI, phMRI and how functional connectivity (rsfMRI between several brain regions is affected, both in acute and extended time frames. Furthermore, fMRI techniques can be used to assess/explore the efficacy of novel treatments in depth, both in fundamental research as well as in preclinical settings. In conclusion, by describing several exemplary studies, we aim to highlight the advantages of functional MRI in exploring the acute and long-term effects of pharmacological substances and/or pathology on brain functioning along with

Beyond reverse pharmacology: Mechanism-based screening of Ayurvedic drugs.

Lele, R D

2010-10-01

This paper reviews the pharmacology of Indian medicinal plants, starting with the historical background of European work on the subject beginning as early as the 17th century, and tracing its history through the work of Sen and Bose in the 1930's, and Vakhil's historic 1949 paper on Sarpaghanda. The often crucial role of patient feedback in early discoveries is highlighted, as is the time lag between proof of pharmacological action and identification of the active principle, and subsequent elucidation of mechanism of action. In the case of Indian plants in the 20th century this process sometimes took almost 50 years. Reserpine and its mechanisms are given in detail, and its current relevance to public health discussed. The foundation of present day methods of pharmacology is briefly presented so the complexity of methods used to identify properties of Ayurveda derived drugs like forskolin and baicalein, and their bioavailability, may be better appreciated. Ayurveda derived anti-oxidants and their levels of action, immuno-modulators, particularly with respect to the NF-kB pathway and its implications for cancer control, are all considered. The example of curcumin derived from turmeric is explained in more detail, because of its role in cancer prevention. Finally, the paper emphasizes the importance of Ayurveda's concepts of rasayana as a form of dietary chemo-prevention; the significance of ahar, diet, in Ayurveda's aspiration to prevent disease and restore health thus becomes clear. Understood in this light, Ayurveda may transcend pharmacology as a treatment paradigm.

Mokhber-Dezfuli, Najmeh; Saeidnia, Soodabeh; Gohari, Ahmad Reza; Kurepaz-Mahmoodabadi, Mahdieh

2014-01-01

The genus Berberis (Berberidaceae) includes about 500 species worldwide, some of which are widely cultivated in the north-eastern regions of Iran. This genus consists of spiny deciduous evergreen shrubs, characterized by yellow wood and flowers. The cultivation of seedless barberry in South Khorasan goes back to two hundred years ago. Medicinal properties for all parts of these plants have been reported, including: Antimicrobial, antiemetic, antipyretic, antioxidant, anti-inflammatory, anti-arrhythmic, sedative, anti-cholinergic, cholagogic, anti-leishmaniasis, and anti-malaria. The main compounds found in various species of Berberis, are berberine and berbamine. Phytochemical analysis of various species of this genus revealed the presence of alkaloids, tannins, phenolic compounds, sterols and triterpenes. Although there are some review articles on Berberis vulgaris (as the most applied species), there is no review on the phytochemical and pharmacological activities of other well-known species of the genus Berberis. For this reason, the present review mainly focused on the diverse secondary metabolites of various species of this genus and the considerable pharmacological and biological activities together with a concise story of the botany and cultivation.

Science.gov (United States)

2013-01-01

Background Owning a pet dog could potentially improve child health through encouraging participation in physical activity, through dog walking. However, evidence to support this is limited and conflicting. In particular, little is known about children’s participation in dog walking and factors that may be associated with this. The objective of this study was to describe the participation of children in dog walking, including their own and those belonging to somebody else, and investigate factors associated with regular walking with their own pet dog. Methods Primary school children (n=1021, 9–10 years) from a deprived area of Liverpool were surveyed during a ‘fitness fun day’ as part of the SportsLinx project. The ‘Child Lifestyle and Pets’ survey included questions about pet ownership, pet attachment, and dog walking. Multivariable logistic regression models were used to investigate factors associated with walking any dog, or their own dog, several times a day or more, including level of attachment to the dog, dog type, and sociodemographic factors. Results Overall, 15.4% of children reported walking with any dog (their own or belonging to a friend or family member) ≥ once daily, 14.1% several times a week, 27.6% ≤ once a week, and 42.8% never. Dog owning children (37.1% of the population) more often reported dog walking ‘several times a week or more’ (OR=12.30, 95% CI=8.10-18.69, Ppet dogs may be an opportunity for increasing physical activity in 9–10 year old children. The identification of stronger attachment to dogs regularly walked is similar to findings in adult studies. PMID:24015895

Background Alkaptonuria is a rare, debilitating autosomal recessive disorder affecting tyrosine metabolism. Deficiency of homogentisate 1,2-dioxygenase leads to increased homogentisic acid which is deposited as ochronotic pigment. Clinical sequelae include severe early onset osteoarthritis, increased renal and prostate stone formation and cardiac complications. Treatment has been largely based on analgaesia and arthroplasty. The National Alkaptonuria Centre in Liverpool has been using 2 mg nitisinone (NTBC) off-license for all patients in the United Kingdom with alkaptonuria and monitoring the tyrosine metabolite profiles. Methods Patients with confirmed alkaptonuria are commenced on 2 mg dose (alternative days) of NTBC for three months with daily dose thereafter. Metabolite measurement by LC-MS/MS is performed at baseline, day 4, three-months, six-months and one-year post-commencing NTBC. Thereafter, monitoring and clinical assessments are performed annually. Results Urine homogentisic acid concentration decreased from a mean baseline 20,557 µmol/24 h (95th percentile confidence interval 18,446-22,669 µmol/24 h) by on average 95.4% by six months, 94.8% at one year and 94.1% at two year monitoring. A concurrent reduction in serum homogentisic acid concentration of 83.2% compared to baseline was also measured. Serum tyrosine increased from normal adult reference interval to a mean ± SD of 594 ± 184 µmol /L at year-two monitoring with an increased urinary excretion from 103 ± 81 µmol /24 h at baseline to 1071 ± 726 µmol /24 h two years from therapy. Conclusions The data presented represent the first longitudinal survey of NTBC use in an NHS service setting and demonstrate the sustained effect of NTBC on the tyrosine metabolite profile.

Neurotransmitter signaling pathways required for normal development in Xenopus laevis embryos: a pharmacological survey screen.

Science.gov (United States)

Sullivan, Kelly G; Levin, Michael

2016-10-01

Neurotransmitters are not only involved in brain function but are also important signaling molecules for many diverse cell types. Neurotransmitters are widely conserved, from evolutionarily ancient organisms lacking nervous systems through man. Here, results are reported from a loss- and gain-of-function survey, using pharmacological modulators of several neurotransmitter pathways to examine possible roles for these pathways in normal embryogenesis. Applying reagents targeting the glutamatergic, adrenergic and dopaminergic pathways to embryos of Xenopus laevis from gastrulation to organogenesis stages, we observed and quantified numerous malformations, including craniofacial defects, hyperpigmentation, muscle mispatterning and miscoiling of the gut. These data implicate several key neurotransmitters in new embryonic patterning roles, reveal novel earlier stages for processes involved in eye development, suggest new targets for subsequent molecular-genetic investigation, and highlight the necessity for in-depth toxicology studies of psychoactive compounds to which human embryos might be exposed during pregnancy. © 2016 Anatomical Society.

α-Mangostin from Garcinia mangostana Linn: An updated review of its pharmacological properties

Directory of Open Access Journals (Sweden)

Mohamed Yousif Ibrahim

2016-05-01

Full Text Available Over the past decades, various studies have highlighted the pure natural compound, α-mangostin as their main topic. The compound’s pre-clinical and pharmacological properties have been recognized and defined in these studies. α-Mangostin shows strong pharmacological effects in in vitro and in vivo model systems by targeting a number of vital cellular factors through various mechanisms of action. Despite its important molecular versatility, the α-mangostin still has limited clinical application. In order to optimize the conditions of this compound as a chemotherapeutic and chemopreventive agent, for instance in diseases such as cancer, obesity, diabetes as well as inflammatory disorders, the recent tendency is to limit the range of its pharmacological properties. The present work reviews recent studies on the central and potential pharmacological principles as well as the preclinical applications of the α-mangostin.

Pharmacology is a crucial component of medications administration in nursing, yet nursing students generally find it difficult and self-rate their pharmacology skills as low. To evaluate nursing students learning pharmacology with the Pharmacology Inter-Leaved Learning-Cells environment, a novel approach to modeling biochemical interactions using a multiscale, computer-based model with a complexity perspective based on a small set of entities and simple rules. This environment represents molecules, organelles and cells to enhance the understanding of cellular processes, and combines these cells at a higher scale to obtain whole-body interactions. Sophomore nursing students who learned the pharmacology of diabetes mellitus with the Pharmacology Inter-Leaved Learning-Cells environment (experimental group; n=94) or via a lecture-based curriculum (comparison group; n=54). A quasi-experimental pre- and post-test design was conducted. The Pharmacology-Diabetes-Mellitus questionnaire and the course's final exam were used to evaluate students' knowledge of the pharmacology of diabetes mellitus. Conceptual learning was significantly higher for the experimental than for the comparison group for the course final exam scores (unpaired t=-3.8, pLearning with complexity-based computerized models is highly effective and enhances the understanding of moving between micro and macro levels of the biochemical phenomena, this is then related to better understanding of medication actions. Moreover, the Pharmacology Inter-Leaved Learning-Cells approach provides a more general reasoning scheme for biochemical processes, which enhances pharmacology learning beyond the specific topic learned. The present study implies that deeper understanding of pharmacology will support nursing students' clinical decisions and empower their proficiency in medications administration.

2018-06-01

Full Text Available Purpose/objectives: The aim of this study is to present a modification of the structure of the pharmacology educational experience for dental students as a result of the early introduction of a pharmacology course into the pre-professional curriculum. Methods: Three courses of professional dental pharmacology were modified before and/or after delivery by developing general course learning outcomes, lecture-by-lecture learning outcomes and theme mapping to align topics taught within these courses and with those taught in the pre-professional dental program. Results: Final proposals for three professional dental pharmacology courses, which are distributed over three professional years, were prepared based on teaching experience and theme mapping. Topics were added, deleted, transferred from one course to another to afford courses that are fully aligned, relatively comprehensive, longitudinal, with focus on topics relevant to the dental practice without redundancy. In addition, the design of these courses took into consideration the level of coverage of the pre-professional dental pharmacology course. Conclusions: This longitudinal inclusion of pharmacology courses form the second pre-professional year to the third professional year is expected to improve dental students’ pharmacology education experience. Although the last of these courses is a pharmacotherapeutic course, more courses with clinically oriented therapeutic approach are recommended.

Full Text Available Background and objectives: Phyllanthus emblica L. (Phyllanthaceae, commonly known as Indian gooseberry, is an endemic plant to the tropical and subtropical areas in china, India and Thailand. The plant is extensively used in Chinese, Ayurveda, and traditional Persian medicine (TPM. In addition, there are numerous reports on pharmacological and clinical activities of gooseberry in current medicine. The present review was performed to compile the phytochemical and pharmacological data on P. emblica in order to draw a window for further research.  Methods: Databases such as Scopus, ScienceDirect and PubMed were searched for the term “P. emblica” up to 1st September, 2017. Papers concerning pharmacology and phytochemistry of the plant were gathered and analyzed. On the contrary, agriculture and genetic contents were excluded. Results: Over all, 80 papers were selected. The herb revealed to possess anti-diabetic, anti-oxidant, anti-proliferative, anti-inflammatory, antidepressant, larvicidal, anti-asthmatic, antiulcer, anti-aging, anti-carcinogenic, anti-tumor, anti-genotoxicity, anti-microbial, anticholinergic, antispasmodic, gastroprotective, anti-plasmodia, and antinociceptive activities as well as antidote effect against certain elements. The fruits are also useful in brain and gastrointestinal diseases and can be beneficial in hearth protection. Remarkably, many of those properties have been mentioned in TPM manuscripts.  Conclusion: Despite numerous pharmacological activities for P. emblica, there is still a gap between the in vivo and human studies which should be covered by more comprehensive and complementary studies. Many compounds have been isolated and elucidated from this plant which can be good candidates for various related activities and also as new natural medicaments in novel drug discovery.

2012-06-01

Adherence to treatment in patients on hemodialysis is not a simple process. Strategies to promote adherence will meet the need for improvements in the process of orientation concerning the disease and its pharmacological treatment. To identify compliance with pharmacological treatment of patients on hemodialysis and the main factors related to it we used the Adherence Scale. Observational, descriptive and cross-sectional study. Interviews were conducted to collect socioeconomic, pharmacological data, as well as those regarding self-reported adherence to drug. Out of the 65 participants, 55.4% showed non-compliance. The mean number of drugs used was 4.1 ± 2.5 (self-report) and 6.2 ± 3.0 (prescription). Statistical analysis showed significant differences concerning compliance at different ages (> 60 years are more adherent). A significant proportion of patients have difficulty to comply with treatment and the main factor was forgetfulness. Regarding age, elderly patients are more adherent to treatment. The low level of knowledge about the used drugs may be one of the reasons for the lack of adherence, and the patient's orientation process by a team of multiprofessionals involved in assisting is a strategy to promote adherence.

2015-01-01

Full Text Available This paper reviews the latest understanding of biological and pharmacological properties of osthole (7-methoxy-8-(3-methyl-2-butenyl-2H-1-benzopyran-2-one, a natural product found in several medicinal plants such as Cnidium monnieri and Angelica pubescens. In vitro and in vivo experimental results have revealed that osthole demonstrates multiple pharmacological actions including neuroprotective, osteogenic, immunomodulatory, anticancer, hepatoprotective, cardiovascular protective, and antimicrobial activities. In addition, pharmacokinetic studies showed osthole uptake and utilization are fast and efficient in body. Moreover, the mechanisms of multiple pharmacological activities of osthole are very likely related to the modulatory effect on cyclic adenosine monophosphate (cAMP and cyclic adenosine monophosphate (cGMP level, though some mechanisms remain unclear. This review aims to summarize the pharmacological properties of osthole and give an overview of the underlying mechanisms, which showcase its potential as a multitarget alternative medicine.

2018-06-12

Cistanches Herba is an Orobanchaceae parasitic plant. As a commonly used Traditional Chinese Medicine (TCM), its traditional functions include treating kidney deficiency, impotence, female infertility and senile constipation. Chemical analysis of Cistanches Herba revealed that phenylethanoid glycosides, iridoids, lignans, oligosaccharides, and polysaccharides were the main constituents. Pharmacological studies demonstrated that Cistanches Herba exhibited neuroprotective, immunomodulatory, hormonal balancing, anti-fatigue, anti-inflammatory, hepatoprotection, anti-oxidative, anti-bacterial, anti-viral, and anti-tumor effects, etc. The aim of this review is to provide updated, comprehensive and categorized information on the phytochemistry, pharmacological research and pharmacokinetics studies of the major constituents of Cistanches Herba. The literature search was conducted by systematic searching multiple electronic databases including SciFinder, ISI Web of Science, PubMed, Google Scholar and CNKI. Information was also collected from journals, local magazines, books, monographs. To date, more than 100 compounds have been isolated from this genus, include phenylethanoid glycosides, carbohydrates, lignans, iridoids, etc. The crude extracts and isolated compounds have exhibited a wide range of in vitro and in vivo pharmacologic effects, such as neuroprotective, immunomodulatory, anti-inflammatory, hepatoprotection, anti-oxidative, anti-bacterial, and anti-tumor effects. The phenylethanoid glycosides, echinacoside and acteoside have attracted the most attention for their significantly neuropharmacology effects. Pharmacokinetic studies of echinacoside and acteoside also have also been summarized. Phenylethanoid glycosides have demonstrated wide pharmacological actions and have great clinical value if challenges such as poor bioavailability, fast and extensive metabolism are addressed. Apart from phenylethanoid glycosides, other constituents of Cistanches Herba, their

The Caenorhabditis elegans model is a rapid and inexpensive method to address pharmacologic questions. We describe the use of C. elegans to explore 2 pharmacologic questions concerning candidate antiobesity drugs and illustrate its potential usefulness in pharmacologic research: (1) to determine a ratio of betahistine-olanzapine that blocks the olanzapine-induced intestinal fat deposition (IFD) as detected by Nile red staining and (2) to identify the mechanism of action of a pharmaceutical candidate AB-101 that reduces IFD. Olanzapine (53 μg/mL) increased the IFD (12.1 ± 0.1%, P < 0.02), which was blocked by betahistine (763 μg/mL, 39.3 ± 0.01%, P < 0.05) in wild-type C. elegans (N2). AB-101 (1.0%) reduced the IFD in N2 (P < 0.05), increased the pharyngeal pumping rate (P < 0.05), and reversed the elevated IFD induced by protease inhibitors atazanavir and ritonavir (P < 0.05). AB-101 did not affect IFD in a ACS null mutant strain acs-4(ok2872) III/hT2[bli-4(e937) let-?(q782) qIs48](I;III) suggesting an involvement of the lipid oxidation pathway and an upregulation of CPT-1. Our studies suggest that C. elegans may be used as a resource in pharmacologic research. This article is intended to stimulate a greater appreciation of its value in the development of new pharmaceutical interventions.

2010-01-01

Background Pharmacological treatment has been advocated as a first line therapy for Peripheral Arterial Disease (PAD) patients suffering from intermittent claudication. Previous studies document the ability of pharmacological treatment to increase walking distances. However, the effect of pharmacological treatment on gait biomechanics in PAD patients has not been objectively evaluated as is common with other gait abnormalities. Methods Sixteen patients were prescribed an FDA approved drug (Pentoxifylline or Cilostazol) for the treatment of symptomatic PAD. Patients underwent baseline gait testing prior to medication use which consisted of acquisition of ground reaction forces and kinematics while walking in a pain free state. After three months of treatment, patients underwent repeat gait testing. Results Patients with symptomatic PAD had significant gait abnormalities at baseline during pain free walking as compared to healthy controls. However, pharmacological treatment did not produce any identifiable alterations on the biomechanics of gait of the PAD patients as revealed by the statistical comparisons performed between pre and post-treatment and between post-treatment and the healthy controls. Conclusions Pharmacological treatment did not result in statistically significant improvements in the gait biomechanics of patients with symptomatic PAD. Future studies will need to further explore different cohorts of patients that have shown to improve significantly their claudication distances and/or their muscle fiber morphology with the use of pharmacological treatment and determine if this is associated with an improvement in gait biomechanics. Using these methods we may distinguish the patients who benefit from pharmacotherapy and those who do not. PMID:20529284

Stephania rotunda Lour. (Menispermaceae) is an important traditional medicinal plant that is grown in Southeast Asia. The stems, leaves, and tubers have been used in the Cambodian, Lao, Indian and Vietnamese folk medicine systems for years to treat a wide range of ailments, including asthma, headache, fever, and diarrhoea. To provide an up-to-date, comprehensive overview and analysis of the ethnobotany, phytochemistry, and pharmacology of Stephania rotunda for its potential benefits in human health, as well as to assess the scientific evidence of traditional use and provide a basis for future research directions. Peer-reviewed articles on Stephania rotunda were acquired via an electronic search of the major scientific databases (Pubmed, Google Scholar, and ScienceDirect). Data were collected from scientific journals, theses, and books. The traditional uses of Stephania rotunda were recorded in countries throughout Southeast Asia (Cambodia, Vietnam, Laos, and India). Different parts of Stephania rotunda were used in traditional medicine to treat about twenty health disorders. Phytochemical analyses identified forty alkaloids. The roots primarily contain l-tetrahydropalmatine (l-THP), whereas the tubers contain cepharanthine and xylopinine. Furthermore, the chemical composition differs from one region to another and according to the harvest period. The alkaloids exhibited approximately ten different pharmacological activities. The main pharmacological activities of Stephania rotunda alkaloids are antiplasmodial, anticancer, and immunomodulatory effects. Sinomenine, cepharanthine, and l-stepholidine are the most promising components and have been tested in humans. The pharmacokinetic parameters have been studied for seven compounds, including the three most promising compounds. The toxicity has been evaluated for liriodenine, roemerine, cycleanine, l-tetrahydropalmatine, and oxostephanine. Stephania rotunda is traditionally used for the treatment of a wide range of

Thompson, Corbin G; Gay, Cynthia L; Kashuba, Angela D M

2017-06-01

An increasing amount of evidence suggests that HIV replication persists in gut-associated lymphoid tissues (GALT), despite treatment with combination antiretroviral therapy (cART). Residual replication in this compartment may propagate infection at other sites in the body and contribute to sustained immune dysregulation and delayed immune recovery. Therefore, it is important to focus efforts on eliminating residual replication at this site. There are several challenges to accomplishing this goal, including low antiretroviral (ARV) exposure at specific tissue locations within GALT, which might be overcome by using the tools of clinical pharmacology. Here, we summarize the evidence for GALT as a site of residual HIV replication, highlight the consequences of persistent infection in tissues, identify current pharmacologic knowledge of drug exposure in GALT, define the challenges that hinder eradication from this site, and propose several avenues for pharmacologic intervention.

Tinnon, Elizabeth; Newton, Rebecca

This study examined the effectiveness of simulation as a method of teaching pharmacological concepts to nursing students; perceptions of satisfaction with simulation as a teaching strategy were also evaluated. Second-semester juniors participated in three simulations and completed the National League for Nursing Student Satisfaction and Self-Confidence in Learning Questionnaire and the Student Evaluation of Educational Quality Survey; a control group received traditional lectures. A unit exam on anticoagulant therapy content was administered to measure effectiveness. Findings support that simulation is as effective as traditional lecture for an undergraduate pharmacology course.

The metabolic syndrome includes a constellation of several well-established risk factors, which need to be aggressively treated in order to prevent overt type 2 diabetes and cardiovascular disease. While recent guidelines for the treatment of individual components of the metabolic syndrome focus on cardiovascular benefits as resulted from clinical trials, specific recent recommendations on the pharmacological management of metabolic syndrome are lacking. The objective of present paper was to review the therapeutic options for metabolic syndrome and its components, the available evidence related to their cardiovascular benefits, and to evaluate the extent to which they should influence the guidelines for clinical practice. Areas covered: A Medline literature search was performed to identify clinical trials and meta-analyses related to the therapy of dyslipidemia, arterial hypertension, glucose metabolism and obesity published in the past decade. Expert commentary: Our recommendation for first-line pharmacological are statins for dyslipidemia, renin-angiotensin-aldosteron system inhibitors for arterial hypertension, metformin or sodium/glucose cotransporter 2 inhibitors or glucagon-like peptide 1 receptor agonists (GLP-1RAs) for glucose intolerance, and the GLP-1RA liraglutide for achieving body weight and waist circumference reduction.

We studied patients with epilepsy by neuro-pharmacological functional MRI technique using diazepam. Five normal volunteers and 7 patients with epilepsy were investigated. MRI was performed by a 1.5 T unit (SIGNA Horizon, GE) using the following parameters: TR/TE 5000 msec/80 msec, FA 90 deg, FOV 200 mm, matrix 128 x 128, slice thickness 7 mm. We performed MRI scanning over 5 minutes (2 minutes before and 3 minutes after injection of diazepam) for each 1 session; we scanned 3 sessions for each patient at intervals of 5 minutes. The diazepam was injected rapidly from the antecubital vein. The dose of diazepam was 0.05 mg/kg/injection (total dose was 0.15 mg/kg). The data were analyzed statistically using t-test. Signal change after administration of diazepam was less than 1 to 2% in healthy volunteers. By contrast, in patient with epilepsy, the signal change was almost 3%, which was significantly greater than that of the normal area (p=0.01). The neuro-pharmacological functional MRI technique using diazepam might be a useful method to identify epileptic foci. (author)

China is abundant in natural medicinal resources. Natural medicine (NP), especially traditional Chinese medicine (TCM), have been widely employed in prevention and treatment of diseases in China for thousands of years, which make a great contribution to health care of Chinese people and the prosperity of the Chinese nation. TCM is the excellence culture inheritance of China and a medicine system with long history, tradition and unique theory and technique. Prescriptions or formula are the main form of TCM and the compatibility and composition of them are made up following the theory of TCM among which the theory of compatibility is the essential part. Clinical application and modern pharmacological study both demonstrated that TCM prescription possesses unique effect in comparison with chemical drugs. However, the pharmacological study of TCM prescription is very difficult due to multiple herbs which contain complicated chemical components in the prescription. So, the key point for the pharmacological study of TCM prescription is to elucidate its integrative effect and the mechanism of action. In recent years, great advances have been achieved in the research on TCM prescription and modern study of TCM prescription, including pharmacological and chemical studies, has becoming a hot research field in China. The pharmacological studies of TCM and NP are conducted with different ways and methods including holistic approaches in various experimental model animals and in vitro experiments in tissue, organ and cell models. In addition, a lot of new technics and methods such as″ omics″ technologies were employed in the molecular level studies, for example, researches on the mechanism of action of TCM and NP. In addition, a lot of new drugs have been developed from TCM prescriptions in China. The classical preparations of TCM, including decoction, pill, powder, ointment and pellet, etc, are prepared with traditional methods. While, the new preparations are similar to

Rocuronium bromide is a routinely used muscle relaxant in anaesthetic practice. Its use, however, is associated with intense pain on injection. While it is well established that rocuronium bromide injection causes pain in awake patients, anaesthetized patients also tend to show withdrawal movements of the limbs when this muscle relaxant is administered. Various strategies, both pharmacological and non-pharmacological, have been studied to reduce the incidence and severity of pain on rocuronium bromide injection. We wanted to find out which of the existing modalities was best to reduce pain on rocuronium injection. The objectives of this review were to assess the ability of both pharmacological and non-pharmacological interventions to reduce or eliminate the pain that accompanies rocuronium bromide administration. We searched the Cochrane Central Register of Controlled Trials (CENTRAL 2013, Issue 7), MEDLINE via Ovid SP (1966 to July 2013) and EMBASE via Ovid SP (1980 to July 2013). We also searched specific websites. We reran the searches in February 2015 and will deal with the 11 studies of interest found through this search when we update the review. We included all randomized controlled trials (RCTs) that compared the use of any drug or a non-pharmacological method with control patients, or those receiving no treatment to reduce the severity of pain with rocuronium injection. Our primary outcome was pain on rocuronium bromide injection measured by a pain score assessment. Our secondary outcomes were rise in heart rate and blood pressure following administration of rocuronium and adverse events related to the interventions. We used the standardized methods for conducting a systematic review as described in the Cochrane Handbook for Systematic Reviews of Interventions. Two authors independently extracted details of trial methodology and outcome data from reports of all trials considered eligible for inclusion. We made all analyses on an intention-to-treat basis

For decades in China, the Yin-Huang-Qing-Fei capsule (YHQFC) has been widely used in the treatment of chronic bronchitis, with good curative effects. Owing to the complexity of traditional Chinese herbal formulas, the pharmacological mechanism of YHQFC remains unclear. To address this problem, a network pharmacology-based strategy was proposed in this study. At first, the putative target profile of YHQFC was predicted using MedChem Studio, based on structural and functional similarities of all available YHQFC components to the known drugs obtained from the DrugBank database. Then, an interaction network was constructed using links between putative YHQFC targets and known therapeutic targets of chronic bronchitis. Following the calculation of four topological features (degree, betweenness, closeness, and coreness) of each node in the network, 475 major putative targets of YHQFC and their topological importance were identified. In addition, a pathway enrichment analysis based on the Kyoto Encyclopedia of Genes and Genomes pathway database indicated that the major putative targets of YHQFC are significantly associated with various pathways involved in anti-inflammation processes, immune responses, and pathological changes caused by asthma. More interestingly, eight major putative targets of YHQFC (interleukin [IL]-3, IL-4, IL-5, IL-10, IL-13, FCER1G, CCL11, and EPX) were demonstrated to be associated with the inflammatory process that occurs during the progression of asthma. Finally, a molecular docking simulation was performed and the results exhibited that 17 pairs of chemical components and candidate YHQFC targets involved in asthma pathway had strong binding efficiencies. In conclusion, this network pharmacology-based investigation revealed that YHQFC may attenuate the inflammatory reaction of chronic bronchitis by regulating its candidate targets, which may be implicated in the major pathological processes of the asthma pathway.

Blood oxygen level-dependent (BOLD) MRI has been effectively used to monitor changes in renal oxygenation. However, R2* (or T2*) is not specific to blood oxygenation and is dependent on other factors. This study investigates the use of a statistical model that takes these factors into account and maps BOLD MRI measurements to blood pO2. Spin echo and gradient echo images were obtained in six Sprague-Dawley rats and R2 and R2* maps were computed. Measurements were made at baseline, post-nitric oxide synthase inhibitor (L-NAME), and post-furosemide administration. A simulation of each region was performed to map R2' (computed as R2*-R2) to blood pO2. At baseline, blood pO2 in the outer medulla was 30.5 ± 1.2 mmHg and 51.9 ± 5.2 mmHg in the cortex, in agreement with previous invasive studies. Blood pO2 was found to decrease within the outer medulla following L-NAME (P pO2 in the cortex increased following furosemide (P pO2 is sensitive to pharmacological challenges, and baseline pO2 is comparable to literature values. Reporting pO2 instead of R2* could lead to a greater clinical impact of renal BOLD MRI and facilitate the identification of hypoxic regions.

Full Text Available Alexander J Sandweiss, Todd W VanderahDepartment of Pharmacology, College of Medicine, University of Arizona, Tucson, AZ, USAAbstract: Addiction is a chronic disorder in which consumption of a substance or a habitual behavior becomes compulsive and often recurrent, despite adverse consequences. Substance p (SP is an undecapeptide and was the first neuropeptide of the neurokinin family to be discovered. The subsequent decades of research after its discovery implicated SP and its neurokinin relatives as neurotransmitters involved in the modulation of the reward pathway. Here, we review the neurokinin literature, giving a brief historical perspective of neurokinin pharmacology, localization in various brain regions involved in addictive behaviors, and the functional aspects of neurokinin pharmacology in relation to reward in preclinical models of addiction that have shaped the rational drug design of neurokinin antagonists that could translate into human research. Finally, we will cover the clinical investigations using neurokinin antagonists and discuss their potential as a therapy for drug abuse.Keywords: reward, substance p, alcohol, morphine, cocaine, dopamine

Amphetamine, past and present – a pharmacological and clinical perspective

Smith, Sharon L; Gosden, Jane; Nutt, David J

2013-01-01

Amphetamine was discovered over 100 years ago. Since then, it has transformed from a drug that was freely available without prescription as a panacea for a broad range of disorders into a highly restricted Controlled Drug with therapeutic applications restricted to attention deficit hyperactivity disorder (ADHD) and narcolepsy. This review describes the relationship between chemical structure and pharmacology of amphetamine and its congeners. Amphetamine’s diverse pharmacological actions translate not only into therapeutic efficacy, but also into the production of adverse events and liability for recreational abuse. Accordingly, the balance of benefit/risk is the key challenge for its clinical use. The review charts advances in pharmaceutical development from the introduction of once-daily formulations of amphetamine through to lisdexamfetamine, which is the first d-amphetamine prodrug approved for the management of ADHD in children, adolescents and adults. The unusual metabolic route for lisdexamfetamine to deliver d-amphetamine makes an important contribution to its pharmacology. How lisdexamfetamine’s distinctive pharmacokinetic/pharmacodynamic profile translates into sustained efficacy as a treatment for ADHD and its reduced potential for recreational abuse is also discussed.

2015-12-01

Over the last decade, zebrafish (Danio rerio) have become valuable as a complementary model in behavioral pharmacology, opening a new avenue for understanding the relationships between drug action and behavior. This species offers a useful intermediate approach bridging the gap between in vitro studies and traditional mammalian models. Zebrafish offer great advantages of economy compared to their rodent counterparts, their complex brains and behavioral repertoire offer great translational potential relative to in vitro models. The development and validation of a variety of tests to measure behavior, including cognition, in zebrafish have set the stage for the use of this animal for behavioral pharmacology studies. This has led to research into the basic mechanisms of cognitive function as well as screening for potential cognition-improving drug therapies, among other lines of research. As with all models, zebrafish have limitations, which span pharmacokinetic challenges to difficulties quantifying behavior. The use, efficacy and limitations associated with a zebrafish model of cognitive function are discussed in this review, within the context of behavioral pharmacology. Copyright © 2015 Elsevier Inc.

Pharmacologic pre- and postconditioning for stroke: Basic mechanisms and translational opportunity

Directory of Open Access Journals (Sweden)

Elga Esposito

2015-01-01

Full Text Available Beyond reperfusion therapies, there are still no widely effective therapies for ischemic stroke. Although much progress has been made to define the molecular pathways involved, targeted neuroprotective strategies have often failed in clinical trials. An emerging hypothesis suggests that focusing on single targets and mechanisms may not work since ischemic stroke triggers multiple pathways in multiple cell types. In this review, we briefly survey and assess the opportunities that may be afforded by pre- and postconditioning therapies, with particular attention to pharmacologic pre- and postconditioning. Pharmacologic conditioning may be defined as the use of chemical agents either before or shortly after stroke onset to trigger mechanisms of endogenous tolerance that are thought to involve evolutionarily conserved signals that offer broad protection against ischemia. Importantly, many of the pharmacologic agents may also have been previously used in humans, thus providing hope for translating basic mechanisms into clinical applications.

Piper, Brian J; Telku, Hassenet M; Lambert, Drew A

2015-01-01

Disclosure of potential conflicts of interest (CoI) is a standard practice for many biomedical journals but not for educational materials. The goal of this investigation was to determine whether the authors of pharmacology textbooks have undisclosed financial CoIs and to identify author characteristics associated with CoIs. The presence of potential CoIs was evaluated by submitting author names (N = 403; 36.3% female) to a patent database (Google Scholar) as well as a database that reports on the compensation ($USD) received from 15 pharmaceutical companies (ProPublica's Dollars for Docs). All publications (N = 410) of the ten highest compensated authors from 2009 to 2013 and indexed in Pubmed were also examined for disclosure of additional companies that the authors received research support, consulted, or served on speaker's bureaus. A total of 134 patents had been awarded (Maximum = 18/author) to textbook authors. Relative to DiPiro's Pharmacotherapy: A Pathophysiologic Approach, contributors to Goodman and Gilman's Pharmacological Basis of Therapeutics and Katzung's Basic and Clinical Pharmacology were more frequently patent holders (OR = 6.45, P 1 patent (OR = 0.15, P < .0005). A total of $2,411,080 USD (28.3% for speaking, 27.0% for consulting, and 23.9% for research), was received by 53 authors (Range = $299 to $310,000/author). Highly compensated authors were from multiple fields including oncology, psychiatry, neurology, and urology. The maximum number of additional companies, not currently indexed in the Dollars for Docs database, for which an author had potential CoIs was 73. Financial CoIs are common among the authors of pharmacology and pharmacotherapy textbooks. Full transparency of potential CoIs, particularly patents, should become standard procedure for future editions of educational materials in pharmacology.

In this study, nanoporous gold supercapacitors were produced by electrochemical dealloying of gold-silver alloy. Scanning electron microscopy and energy dispersive X-ray spectroscopy confirmed completion of the dealloying process and generation of a porous gold material with approximately 10 nm diameter pores. Cyclic voltammetry and chronoamperometry of the nanoporous gold electrodes indicated that these materials exhibited supercapacitor behavior. The storage capacity of the electrodes measured by chronoamperometry was approximately 3 mC at 200 mV. Electrochemical storage and voltage-controlled delivery of two model pharmacologic agents, benzylammonium and salicylic acid, was demonstrated. These results suggest that capacitance-based storage and delivery of pharmacologic agents may serve as an alternative to conventional drug delivery methods.

2004-01-01

Problem-based learning (PBL) requires active student participation and the use of clinical cases as a trigger to learn within a given area. It has gained much attention as a pedagogic alternative in the course of reform in medica education due to information overload. From discipline-based consideration, it is interesting to understand the views of department heads of pharmacology about implementing PBL for their medical students. According to a general survey from the heads of the department of pharmacology across medical schools in Taiwan, we found that although serious reservation about the approach remains, many departments indeed look forward to including PBL component in their pharmacology curriculum.

Pharmacological treatment of chronic constipation: a literature review

Directory of Open Access Journals (Sweden)

2016-07-01

Full Text Available Chronic constipation is a very common disease that is particularly commonplace among members of the elderly population. It is one of the most widespread bowel disorders, and it causes significant pain and discomfort; as such, it usually requires medical attention. The major causes of constipation are slow colonic movements and/or functional gastrointestinal disorders. This review aimed to examine the pharmacological treatments that are currently available for chronic constipation. To develop insights into the causes and treatments of chronic constipation, relevant review articles that were published on the Pubmed, Cochrane database, and Embase websites, were examined. The outputs of these studies indicated that high daily intake of fibers and fluids in addition to regular exercise can be very helpful in avoiding and treating constipation. The pharmacological treatments that are administered to treat this disease typically increase the water content of the bowel lumen, and this leads to more regular bowel movements. Novel drugs have been introduced to treat constipation, and many of these are now subject to formal research studies. Since constipation can facilitate the development of other gastrointestinal diseases, it is important that we develop an understanding the therapeutic treatments that are available with the intention of identifying which of these may represent the most effective method for treating this disease. With that objective in mind, this review was undertaken to review the clinical effectiveness of the different pharmacological treatments that are employed to treat or prevent constipation.

While pharmacologic stress single photon emission computed tomography myocardial perfusion imaging (SPECT-MPI) is used for noninvasive evaluation of patients who are unable to perform treadmill exercise, its impact on net reclassification improvement (NRI) of prognosis is unknown. We evaluated the prognostic value of pharmacologic stress MPI for prediction of cardiovascular death or non-fatal myocardial infarction (MI) within 1 year at a single-center, university-based laboratory. We examined continuous and categorical NRI of pharmacologic SPECT-MPI for prediction of outcomes beyond clinical factors alone. Six thousand two hundred forty patients (median age 66 years [IQR 56-74], 3466 men) were studied and followed for 5963 person-years. SPECT-MPI variables associated with increased risk of cardiovascular death or non-fatal MI included summed stress score, stress ST-shift, and post-stress resting left ventricular ejection fraction ≤50%.

Current strategies for non-pharmacological therapy of long-standing persistent atrial fibrillation

Directory of Open Access Journals (Sweden)

Teiichi Yamane, MD, PhD

2012-06-01

Full Text Available Non-pharmacological rhythm control of atrial fibrillation (AF is becoming increasingly important in our aging society. Advancement of catheter ablation techniques in the last decade has provided a cure for AF patients, with a nearly established efficiency for paroxysmal cases. However, since ablation of persistent/chronic AF cases is still challenging, early treatment of paroxysmal AF before transformation to the persistent/chronic form is mandatory. Although there is a consensus that pulmonary vein isolation is the first-line approach for ablation of long-standing persistent AF, similar to that for paroxysmal AF, there are still wide variations in the adjunctive approach to modify the atrial substrate of persistent AF (anatomical linear ablation, electrogram-based complex fractionated atrial electrogram ablation, ganglionated plexus ablation, etc.. Since data comparing the effectiveness of these adjunctive approaches are still lacking, large-scale controlled trials evaluating the effect of catheter ablation in diverse patient populations on a long-term basis are needed to establish the appropriate approach for long-standing persistent AF. Furthermore, the development of de novo ablation methods (new energies, new targets, etc. is expected to improve ablation outcome in patients with long-standing persistent AF.

Management of Depression in Patients with Dementia: Is Pharmacological Treatment Justified?

Science.gov (United States)

Ford, Andrew H; Almeida, Osvaldo P

2017-02-01

Depression in the context of dementia is common and contributes to poorer outcomes in individuals and those who care for them. Non-pharmacological treatments are the preferred initial approach to managing these symptoms but data in support of these are scarce. There are a number of pharmacological treatment options available to clinicians but efficacy is uncertain and concern about potential side effects in an aging and vulnerable population needs to be taken into consideration. This review aims to provide a concise overview of pharmacological treatments for depression in dementia. Antidepressants are the mainstay of pharmacological treatment for clinically significant depression in the general population but evidence to support their use in dementia is mixed. Trials of antidepressants should generally be reserved for individuals with depression where the symptoms are distressing and surpass the threshold for major depression. Acetylcholinesterase inhibitors and memantine are effective in the symptomatic treatment of Alzheimer's disease but current evidence does not support their use to treat depressive symptoms in dementia. Similarly, antipsychotics and mood stabilizers have no proven efficacy for depression and the risk of adverse effects seems to outweigh any potential benefit. Pain can be a frequent problem in dementia and may have significant effects on behavior and mood. Preliminary evidence supports a role of adequate analgesia in improving mood in people with dementia.

Albumin, the major circulating protein in blood plasma, can be subjected to an increased level of glycation in a diabetic context. Albumin exerts crucial pharmacological activities through its drug binding capacity, i.e., ketoprofen, and via its esterase-like activity, allowing the conversion of prodrugs into active drugs. In this study, the impact of the glucose-mediated glycation on the pharmacological and biochemical properties of human albumin was investigated. Aggregation product levels and the redox state were quantified to assess the impact of glycation-mediated changes on the structural properties of albumin. Glucose-mediated changes in ketoprofen binding properties and esterase-like activity were evaluated using fluorescence spectroscopy and p-nitrophenyl acetate hydrolysis assays, respectively. With the exception of oxidative parameters, significant dose-dependent alterations in biochemical and functional properties of in vitro glycated albumin were observed. We also found that the dose-dependent increase in levels of glycation and protein aggregation and average molecular mass changes correlated with a gradual decrease in the affinity of albumin for ketoprofen and its esterase-like property. In parallel, significant alterations in both pharmacological properties were also evidenced in albumin purified from diabetic patients. Partial least-squares regression analyses established a significant correlation between glycation-mediated changes in biochemical and pharmacological properties of albumin, highlighting the important role for glycation in the variability of the drug response in a diabetic situation.

Clozapine induced sedation is common but its management is unclear. We analyzed the factors associated with clozapine-induced sedation and the efficacy of common pharmacological strategies. We conducted a naturalistic observational study using two years electronic records of a cohort patients and three analyses: a cross sectional analysis of factors associated with total number of hours slept (as an objective proxy of sedation), and two prospective analyses of which factors were associated with changes in hours slept and the efficacy of two pharmacological strategies. 133 patients were included, of which 64.7% slept at least 9h daily. Among monotherapy patients (n=30), only norclozapine levels (r=.367, p=.03) correlated with hours slept. Using the prospective cohort (n=107), 42 patients decreased the number of hours slept, due to decreasing clozapine (40%) or augmenting with aripiprazole (36%). These two strategies were recommended to 22 (20.6%) and 23 (21.5%) subjects respectively but the majority (81.8% and 73.9%) did not reduce number of hours slept. Thus, pharmacological and non-pharmacological factors are involved in sedation. Norclozapine plasma levels correlated with total sleeping hours. Reducing clozapine and aripiprazole augmentation were associated to amelioration of sedation, although both strategies were effective only in a limited numbers of subjects.

Pharmacological interactions of anti-inflammatory-analgesics in odontology.

Science.gov (United States)

Gómez-Moreno, Gerardo; Guardia, Javier; Cutando, Antonio; Calvo-Guirado, José Luis

2009-02-01

In this second article we describe the more interesting pharmacological interactions in dental practice based on the prescription of analgesic narcotics, paracetamol and non-selective non-steroid anti-inflammatory drugs (NSAI) (which inhibit cyclooxigenase 1 -COX 1- and cyclooxigenase 2 -COX 2-) and selective NSAIs (COX 2 inhibitors). The importance of preventing the appearance of these pharmacological interactions is because these are medicaments prescribed daily in odontology for moderate pain treatment and inflammation in the oral cavity. Paracetamol can interact with warfarin and therefore care should be taken with chronic alcoholic patients. All NSAIs reduce renal blood flow and consequently are capable of reducing the efficacy of medicaments used for treating arterial hypertension, which act via a renal mechanism. Especial attention should be taken considering the risk of interaction between the antagonists of AT1 receptors of angiostensin II (ARAII) and the NSAIs.

Providing data science support for systems pharmacology and its implications to drug discovery.

Hart, Thomas; Xie, Lei

2016-01-01

The conventional one-drug-one-target-one-disease drug discovery process has been less successful in tracking multi-genic, multi-faceted complex diseases. Systems pharmacology has emerged as a new discipline to tackle the current challenges in drug discovery. The goal of systems pharmacology is to transform huge, heterogeneous, and dynamic biological and clinical data into interpretable and actionable mechanistic models for decision making in drug discovery and patient treatment. Thus, big data technology and data science will play an essential role in systems pharmacology. This paper critically reviews the impact of three fundamental concepts of data science on systems pharmacology: similarity inference, overfitting avoidance, and disentangling causality from correlation. The authors then discuss recent advances and future directions in applying the three concepts of data science to drug discovery, with a focus on proteome-wide context-specific quantitative drug target deconvolution and personalized adverse drug reaction prediction. Data science will facilitate reducing the complexity of systems pharmacology modeling, detecting hidden correlations between complex data sets, and distinguishing causation from correlation. The power of data science can only be fully realized when integrated with mechanism-based multi-scale modeling that explicitly takes into account the hierarchical organization of biological systems from nucleic acid to proteins, to molecular interaction networks, to cells, to tissues, to patients, and to populations.

The Indian Vacuum Society (IVS) was established in 1970. It has over 800 members including many from Industry and R & D Institutions spread throughout India. The society has an active chapter at Kolkata. The society was formed with the main aim to promote, encourage and develop the growth of Vacuum Science, Techniques and Applications in India. In order to achieve this aim it has conducted a number of short term courses at graduate and technician levels on vacuum science and technology on topics ranging from low vacuum to ultrahigh vacuum So far it has conducted 39 such courses at different parts of the country and imparted training to more than 1200 persons in the field. Some of these courses were in-plant training courses conducted on the premises of the establishment and designed to take care of the special needs of the establishment. IVS also regularly conducts national and international seminars and symposia on vacuum science and technology with special emphasis on some theme related to applications of vacuum. A large number of delegates from all over India take part in the deliberations of such seminars and symposia and present their work. IVS also arranges technical visits to different industries and research institutes. The society also helped in the UNESCO sponsored post-graduate level courses in vacuum science, technology and applications conducted by Mumbai University. The society has also designed a certificate and diploma course for graduate level students studying vacuum science and technology and has submitted a syllabus to the academic council of the University of Mumbai for their approval, we hope that some colleges affiliated to the university will start this course from the coming academic year. IVS extended its support in standardizing many of the vacuum instruments and played a vital role in helping to set up a Regional Testing Centre along with BARC. As part of the development of vacuum education, the society arranges the participation of

Owing to the complexity of traditional Chinese herbal formulas, the pharmacological mechanism of YHQFC remains unclear. To address this problem, a network pharmacology-based strategy was proposed in this study. At first, the putative target profile of YHQFC was predicted using MedChem Studio, based on structural and functional similarities of all available YHQFC components to the known drugs obtained from the DrugBank database. Then, an interaction network was constructed using links between putative YHQFC targets and known therapeutic targets of chronic bronchitis. Following the calculation of four topological features (degree, betweenness, closeness, and coreness of each node in the network, 475 major putative targets of YHQFC and their topological importance were identified. In addition, a pathway enrichment analysis based on the Kyoto Encyclopedia of Genes and Genomes pathway database indicated that the major putative targets of YHQFC are significantly associated with various pathways involved in anti-inflammation processes, immune responses, and pathological changes caused by asthma. More interestingly, eight major putative targets of YHQFC (interleukin [IL]-3, IL-4, IL

2015-01-01

Parkinson's disease (PD) is not a single entity but rather a heterogeneous neurodegenerative disorder. The present study aims to conduct a critical systematic review of the literature to describe the main pharmacological strategies to treat cognitive dysfunction and major depressive disorder in PD patients. We performed a search of articles cited in PubMed from 2004 to 2014 using the following MeSH terms (Medical subject headings) "Parkinson disease"; "Delirium," "Dementia," "Amnestic," "Cognitive disorders," and "Parkinson disease"; "depression," "major depressive disorder," "drug therapy." We found a total of 71 studies related to pharmacological treatment in cognitive dysfunction and 279 studies for pharmacological treatment in major depressive disorder. After fulfillment of all the inclusion and exclusion criteria, 13 articles remained for cognitive dysfunction and 11 for major depressive disorder, which are presented and discussed in this study. Further research into non-motor symptoms of PD may provide insights into mechanisms of neurodegeneration, and provide better quality of life by using rational drugs.

Chinese medicinal formulae are the important means of clinical treatment in traditional Chinese medicine. It is urgent to use modern advanced scientific and technological means to reveal the complicated mechanism of Chinese medicinal formulae because they have the function characteristics of multiple components, multiple targets and integrated regulation. The systematic and comprehensive research model of proteomic is in line with the function characteristics of Chinese medicinal formulae, and proteomic has been widely used in the study of pharmacological mechanism of Chinese medicinal formulae. The recent applications of proteomic in pharmacological study of Chinese medicinal formulae in anti-cardiovascular and cerebrovascular diseases, anti-liver disease, antidiabetic, anticancer, anti-rheumatoid arthritis and other diseases were reviewed in this paper, and then the future development direction of proteomic in pharmacological study of Chinese medicinal formulae was put forward. This review is to provide the ideas and method for proteomic research on function mechanism of Chinese medicinal formulae. Copyright© by the Chinese Pharmaceutical Association.

2010-01-01

Cleome viscosa Linn. (Capparidaceae), commonly known as "wild or dog mustard," is an annual, sticky herb found as a common weed all over the plains of India and throughout the tropics of the world. The whole plant and its parts (leaves, seeds, and roots) are widely used in traditional and folkloric systems of medicine. In traditional systems of medicine the plant is reported to possess beneficial effects as an anthelmintic, antiseptic, carminative, antiscorbutic, sudorific, febrifuge, and cardiac stimulant. Following the various traditional claims for the use of C. viscosa (CV) as a cure of numerous diseases, considerable efforts have been made by researchers to verify its utility through scientific pharmacological screenings. The pharmacological studies have shown that CV possesses various notable biological activities such as anthelmintic, antimicrobial, analgesic, antiinflammatory, immunomodulatory, antipyretic, psychopharmacological, antidiarrheal, and hepatoprotective activities. A wide variety of phytoprinciples have been isolated from the plant. The present review is an effort to consolidate traditional, ethnobotanical, phytochemical, and pharmacological information available on C. viscosa.

Familial exudative vitreoretinopathy (FEVR) is characterized by delayed retinal vascular development, which promotes hypoxia-induced pathologic vessels. In severe cases FEVR may lead to retinal detachment and visual impairment. Genetic studies linked FEVR with mutations in Wnt signaling ligand or receptors, including low-density lipoprotein receptor-related protein 5 (LRP5) gene. Here, we investigated ocular pathologies in a Lrp5 knockout (Lrp5(-/-)) mouse model of FEVR and explored whether treatment with a pharmacologic Wnt activator lithium could bypass the genetic defects, thereby protecting against eye pathologies. Lrp5(-/-) mice displayed significantly delayed retinal vascular development, absence of deep layer retinal vessels, leading to increased levels of vascular endothelial growth factor and subsequent pathologic glomeruloid vessels, as well as decreased inner retinal visual function. Lithium treatment in Lrp5(-/-) mice significantly restored the delayed development of retinal vasculature and the intralaminar capillary networks, suppressed formation of pathologic glomeruloid structures, and promoted hyaloid vessel regression. Moreover, lithium treatment partially rescued inner-retinal visual function and increased retinal thickness. These protective effects of lithium were largely mediated through restoration of canonical Wnt signaling in Lrp5(-/-) retina. Lithium treatment also substantially increased vascular tubular formation in LRP5-deficient endothelial cells. These findings suggest that pharmacologic activation of Wnt signaling may help treat ocular pathologies in FEVR and potentially other defective Wnt signaling-related diseases.

Animal models provide preclinical tools to investigate the causal role of genetic mutations and environmental factors in the etiology of autism spectrum disorder (ASD). Knockout and humanized knock-in mice, and more recently knockout rats, have been generated for many of the de novo single gene mutations and copy number variants (CNVs) detected in ASD and comorbid neurodevelopmental disorders. Mouse models incorporating genetic and environmental manipulations have been employed for preclinical testing of hypothesis-driven pharmacological targets, to begin to develop treatments for the diagnostic and associated symptoms of autism. In this review, we summarize rodent behavioral assays relevant to the core features of autism, preclinical and clinical evaluations of pharmacological interventions, and strategies to improve the translational value of rodent models of autism.

To review the available literature evaluating electronic cigarette (e-cigarette) nicotine clinical pharmacology in order to understand the potential impact of e-cigarettes on individual users, nicotine dependence and public health. Literature searches were conducted between 1 October 2012 and 30 September 2013 using key terms in five electronic databases. Studies were included in the review if they were in English and publicly available; non-clinical studies, conference abstracts and studies exclusively measuring nicotine content in e-cigarette cartridges were excluded from the review. Nicotine yields from automated smoking machines suggest that e-cigarettes deliver less nicotine per puff than traditional cigarettes, and clinical studies indicate that e-cigarettes deliver only modest nicotine concentrations to the inexperienced e-cigarette user. However, current e-cigarette smokers are able to achieve systemic nicotine and/or cotinine concentrations similar to those produced from traditional cigarettes. Therefore, user experience is critically important for nicotine exposure, and may contribute to the products' ability to support and maintain nicotine dependence. Knowledge about e-cigarette nicotine pharmacology remains limited. Because a user's e-cigarette experience may significantly impact nicotine delivery, future nicotine pharmacokinetic and pharmacodynamic studies should be conducted in experienced users to accurately assess the products' impact on public health.

Smith, Howard S; Argoff, Charles E

2011-03-26

Neuropathic pain continues to be a difficult and challenging clinical issue to deal with effectively. Painful diabetic polyneuropathy is a complex pain condition that occurs with reasonable frequency in the population and it may be extremely difficult for clinicians to provide patients with effective analgesia. Chronic neuropathic pain may occur in approximately one of every four diabetic patients. The pain may be described as burning or a deep-seated ache with sporadic paroxysms of lancinating painful exacerbations. The pain is often constant, moderate to severe in intensity, usually primarily involves the feet and generally tends to worsen at night. Treatment may be multimodal but largely involves pharmacological approaches. Pharmacological therapeutic options include antidepressants (tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors), α2δ ligands and topical (5%) lidocaine patch. Other agents may be different antiepileptic drugs (carbamazepine, lamotrigine, topiramate), topical capsaicin, tramadol and other opioids. Progress continues with respect to understanding various mechanisms that may contribute to painful diabetic neuropathy. Agents that may hold some promise include neurotrophic factors, growth factors, immunomodulators, gene therapy and poly (adenosine diphosphate-ribose) polymerase inhibitors. It is hoped that in the future clinicians will be able to assess patient pathophysiology, which may help them to match optimal therapeutic agents to target individual patient aberrant mechanisms.

Harnessing Big Data for Systems Pharmacology.

Xie, Lei; Draizen, Eli J; Bourne, Philip E

2017-01-06

Systems pharmacology aims to holistically understand mechanisms of drug actions to support drug discovery and clinical practice. Systems pharmacology modeling (SPM) is data driven. It integrates an exponentially growing amount of data at multiple scales (genetic, molecular, cellular, organismal, and environmental). The goal of SPM is to develop mechanistic or predictive multiscale models that are interpretable and actionable. The current explosions in genomics and other omics data, as well as the tremendous advances in big data technologies, have already enabled biologists to generate novel hypotheses and gain new knowledge through computational models of genome-wide, heterogeneous, and dynamic data sets. More work is needed to interpret and predict a drug response phenotype, which is dependent on many known and unknown factors. To gain a comprehensive understanding of drug actions, SPM requires close collaborations between domain experts from diverse fields and integration of heterogeneous models from biophysics, mathematics, statistics, machine learning, and semantic webs. This creates challenges in model management, model integration, model translation, and knowledge integration. In this review, we discuss several emergent issues in SPM and potential solutions using big data technology and analytics. The concurrent development of high-throughput techniques, cloud computing, data science, and the semantic web will likely allow SPM to be findable, accessible, interoperable, reusable, reliable, interpretable, and actionable.

2018-03-12

Moringa oleifera Lam. ( M. oleifera ), which belongs to the Moringaceae family, is a perennial deciduous tropical tree, and native to the south of the Himalayan Mountains in northern India. M. oleifera is rich in proteins, vitamin A, minerals, essential amino acids, antioxidants, and flavonoids, as well as isothiocyanates. The extracts from M. oleifera exhibit multiple nutraceutical or pharmacological functions including anti-inflammatory, antioxidant, anti-cancer, hepatoprotective, neuroprotective, hypoglycemic, and blood lipid-reducing functions. The beneficial functions of M. oleifera are strongly associated with its phytochemicals such as flavonoids or isothiocyanates with bioactivity. In this review, we summarize the research progress related to the bioactivity and pharmacological mechanisms of M. oleifera in the prevention and treatment of a series of chronic diseases-including inflammatory diseases, neuro-dysfunctional diseases, diabetes, and cancers-which will provide a reference for its potential application in the prevention and treatment of chronic diseases or health promotion.

The Internet is becoming a preferred place to find information. Millions of people go online in the search of health and medical information. Likewise, the demand for Web-based courses grows. This article presents the development, utilization and evaluation of a web-based pharmacology course for nursing students. The course was developed based on 150 commonly used drugs. There were 110 year 1 nursing students took part in the course. After attending six hours face to face lecture of pharmacology over three weeks, students were invited to complete a questionnaire (pre-test) about learning pharmacology. The course materials were then uploaded to a WebCT for student's self-directed learning and attempts to pass two scheduled online quizzes. At the end of the semester, students were given the same questionnaire (post-test). There were a significant increase in the understanding compared with memorizing the subject content, the development of problem solving ability in learning pharmacology and becoming an independent learner (p ,0.05). Online quizzes yielded satisfactory results. In the focused group interview, students appreciated the time flexibility and convenience associated with web-based learning, also, they had made good suggestions in enhancing web-based learning. Web-based approach is promising for teaching and learning pharmacology for nurses and other health-care professionals.

Botanical drugs, synergy, and network pharmacology: forth and back to intelligent mixtures.

Science.gov (United States)

Gertsch, Jürg

2011-07-01

For centuries the science of pharmacognosy has dominated rational drug development until it was gradually substituted by target-based drug discovery in the last fifty years. Pharmacognosy stems from the different systems of traditional herbal medicine and its "reverse pharmacology" approach has led to the discovery of numerous pharmacologically active molecules and drug leads for humankind. But do botanical drugs also provide effective mixtures? Nature has evolved distinct strategies to modulate biological processes, either by selectively targeting biological macromolecules or by creating molecular promiscuity or polypharmacology (one molecule binds to different targets). Widely claimed to be superior over monosubstances, mixtures of bioactive compounds in botanical drugs allegedly exert synergistic therapeutic effects. Despite evolutionary clues to molecular synergism in nature, sound experimental data are still widely lacking to support this assumption. In this short review, the emerging concept of network pharmacology is highlighted, and the importance of studying ligand-target networks for botanical drugs is emphasized. Furthermore, problems associated with studying mixtures of molecules with distinctly different pharmacodynamic properties are addressed. It is concluded that a better understanding of the polypharmacology and potential network pharmacology of botanical drugs is fundamental in the ongoing rationalization of phytotherapy. © Georg Thieme Verlag KG Stuttgart · New York.

Most of the cannabinoids in Cannabis sativa L. have not been fully evaluated for their pharmacological activity. A publication in this issue presents evidence that a plant cannabinoid, Delta(9)-tetrahydrocannabivarin is a potent antagonist of anandamide, a major endogenous cannabinoid. It seems possible that many of the non-psychoactive constituents of this plant will be of biological interest.

The Genus Spilanthes Ethnopharmacology, Phytochemistry, and Pharmacological Properties: A Review

Paulraj, Jayaraj; Govindarajan, Raghavan; Palpu, Pushpangadan

2013-01-01

Spilanthes spp. are popular, over-the-counter remedies; they are sold over the internet under various names and are widely used in traditional medicine in various cultures. This review will summarize the important reports on the ethnopharmacology, botany, phytochemistry, and pharmacological properties as described in the literature from recent years (1920 to 2013). Spilanthes spp. are used for more than 60 types of disorders. They are reported to contain a number of biologically active phytochemicals, although a large number of ethnopharmacological uses have been documented; only a few of these species have been investigated for their chemical and biological activities. The studies are carried out mainly on Spilanthes extracts and a few metabolites substantiate the uses of these plants in traditional medicine. Well-conducted pharmacological studies are still needed for several traditional indications, and the mechanisms of action by which the plant extracts and the active compounds exert their pharmacological effects remain to be studied. They are predominantly used as extracts in personal care products, traditional medicines, and the pharmaceutical and culinary areas. Suggestions are made regarding some of the possible mechanisms of action as to how the known compounds may exert their biological activity. PMID:24454346

How Can Synergism of Traditional Medicines Benefit from Network Pharmacology?

Many prescriptions of traditional medicines (TMs), whose efficacy has been tested in clinical practice, have great therapeutic value and represent an excellent resource for drug discovery. Research into single compounds of TMs, such as artemisinin from Artemisia annua L., has achieved great success; however, it has become evident that a TM prescription (which frequently contains various herbs or other components) has a synergistic effect in effecting a cure or reducing toxicity. Network pharmacology targets biological networks and analyzes the links among drugs, targets, and diseases in those networks. Comprehensive, systematic research into network pharmacology is consistent with the perspective of holisticity, which is a main characteristic of many TMs. By means of network pharmacology, research has demonstrated that many a TM show a synergistic effect by acting at different levels on multiple targets and pathways. This approach effectively bridges the gap between modern medicine and TM, and it greatly facilitates studies into the synergistic actions of TMs. There are different kinds of synergistic effects with TMs, such as synergy among herbs, effective parts, and pure compounds; however, for various reasons, new drug discovery should at present focus on synergy among pure compounds.

Learning how to learn: Meta-learning strategies for the challenges of learning pharmacology.

Nursing students have difficulty with pharmacology courses because of the complicated nomenclature and the difficulty of applying drug information to actual patient care. As part of a new pharmacology course being created, meta-learning strategies designed to diminish the difficulties of learning this difficult content were part of the course pedagogy. Strategies were demonstrated, reviewed in class, and implemented through homework assignments. The setting was an Academic Health Center's School of Nursing in the southern United States. Participants were third-year nursing students in an undergraduate nursing program. Surveys of students' opinions of learning gains were conducted at the end of the course over several semesters. In addition, pharmacology scores on a standardized exit exam were compared prior to implementing the course and after. Students reported learning dry material more easily, having greater confidence, and finding substantial value in the learning strategies. Students indicated the most helpful strategies, in descending order, as follows: making charts to compare and contrast drugs and drug classes, writing out drug flash cards, making or reviewing creative projects, prioritizing information, making or using visual study aids, and using time and repetition to space learning. Implementation of the new course improved pharmacology scores on a standardized exit exam from 67.0% to 74.3%. Overall response to learning strategies was positive, and the increase in the pharmacology standardized exit exam scores demonstrated the effectiveness of this instructional approach.

2013-05-01

The present review gives an overview of current pharmacological treatment options of tic disorders and Tourette Syndrome (TS). After a short summary on phenomenology, clinical course and comorbid conditions we review indications for pharmacological treatment in detail. Unfortunately, standardized and large enough drug trials in TS patients fulfilling evidence based medicine standards are still scarce. Treatment decisions are often guided by individual needs and personal experience of treating clinicians. The present recommendations for pharmacological tic treatment are therefore based on both scientific evidence and expert opinion. As first-line treatment of tics risperidone (best evidence level for atypical antipsychotics) or tiapride (largest clinical experience in Europe and low rate of adverse reactions) are recommended. Aripiprazole (still limited but promising data with low risk for adverse reactions) and pimozide (best evidence of the typical antipsychotics) are agents of second choice. In TS patients with comorbid attention deficit hyperactivity disorder (ADHD) atomoxetine, stimulants or clonidine should be considered, or, if tics are severe, a combination of stimulants and risperidone. When mild to moderate tics are associated with obsessive-compulsive symptoms, depression or anxiety sulpiride monotherapy can be helpful. In more severe cases the combination of risperidone and a selective serotonin reuptake inhibitor should be given. In summary, further studies, particularly randomized, double-blind, placebo-controlled trials including larger and/or more homogenous patient groups over longer periods are urgently needed to enhance the scientific basis for drug treatment in tic disorders.

Linum usitatissimum L., known as common Flax or linseed, from the family Linnaceae, has long been cultivated in different nations due to its applications in medicine and industry. The present study aims to collect nearly all available information about chemical constituents of Flax, as well as pharmacological properties and confirmed clinical usages of it. We searched through databases such as Scopus and PubMed for relevant literatures using the keywords: (Linum usitatissimum), (pharmacology) and (phytochemical) from the beginning to 13 Aug 2017. Nearly 60 relevant papers, relating to pharmacological and phytochemical constituent of L. usitatissimum were selected. According to our researches, various properties were attributed to L. usitatisimum including: antioxidant, immunomodulatory, anti-inflammatory, antimicrobial, Antiprotozoal, insecticidal, Analgesic, anti-hyperlipidemia, Anti-hyperglycemic, Anti-tumor, wound healing and Feticidal activities. There were also many reports to the disease preventive and healing properties of the flax. Diseases like: GI disorders, cardiovascular, urogenital, respiratory diseases and some neurological syndromes were mentioned to be treated by Flax. The application of Flax in drug formulations was also investigated. Despite so much animal studies that have been accomplished, there haven't been enough clinical trials done on pharmacological properties of L. usitatissimum. Therefore this study could be considered as a concise and up to date overview for further facile studies and clinical trials over the valuable plant, L. usitatissimum.

Hamburger, Matthias

2007-01-01

Herbal extracts are widely used and accepted in the population. The pharmacological characterization of such products meets some specific challenges, given the chemical complexity of the active ingredient. An overview is given on modern methods and approaches that can be used for that purpose. In particular, HPLC-based activity profiling is discussed as a means to identify pharmacologically active compounds in an extract, and expression profiling is described as a means for global assessment of effects exerted by multi-component mixtures such as extracts. These methods are illustrated with selected axamples from our labs, including woad (Isatis tinctoria), the traditional Chinese herb Danshen (Salvia miltiorrhiza) and black cohosh (Cimicifuga racemosa).

Pharmacological treatment of sleep disorders and its relationship with neuroplasticity.

Science.gov (United States)

Abad, Vivien C; Guilleminault, Christian

2015-01-01

Sleep and wakefulness are regulated by complex brain circuits located in the brain stem, thalamus, subthalamus, hypothalamus, basal forebrain, and cerebral cortex. Wakefulness and NREM and REM sleep are modulated by the interactions between neurotransmitters that promote arousal and neurotransmitters that promote sleep. Various lines of evidence suggest that sleep disorders may negatively affect neuronal plasticity and cognitive function. Pharmacological treatments may alleviate these effects but may also have adverse side effects by themselves. This chapter discusses the relationship between sleep disorders, pharmacological treatments, and brain plasticity, including the treatment of insomnia, hypersomnias such as narcolepsy, restless legs syndrome (RLS), obstructive sleep apnea (OSA), and parasomnias.

Ney, Denise M.; Blank, Robert D.; Hansen, Karen E.

2014-01-01

Structural Abstract Purpose of review The purpose is to discuss advances in the nutritional and pharmacological management of phenylketonuria (PKU). Recent findings Glycomacropeptide (GMP), a whey protein produced during cheese production, is a low-phe intact protein that represents a new dietary alternative to synthetic amino acids (AAs) for people with PKU. Skeletal fragility is a long-term complication of PKU that based on murine research, appears to result from both genetic and nutritional factors. Skeletal fragility in murine PKU is attenuated with the GMP diet, compared with an AA diet, allowing greater radial bone growth. Pharmacologic therapy with tetrahydrobiopterin (BH4), acting as a molecular chaperone for phenylalanine hydroxylase, increases tolerance to dietary phe in some individuals. Large neutral AAs (LNAA) inhibit phe transport across the intestinal mucosa and blood brain barrier; LNAA are most effective for individuals unable to comply with the low-phe diet. Summary Although a low-phe synthetic AA diet remains the mainstay of PKU management, new nutritional and pharmacological treatment options offer alternative approaches to maintain lifelong low phe concentrations. GMP medical foods provide an alternative to AA formula that may improve bone health, and BH4 permits some individuals with PKU to increase tolerance to dietary phe. Further research is needed to characterize the long-term efficacy of these new approaches for PKU management. PMID:24136088

Phillipou, Andrea; Rossell, Susan L; Wilding, Helen E; Castle, David J

2016-11-30

Treatment for body dysmorphic disorder (BDD) often involves a combination of psychological and pharmacological interventions. However, only a small number of randomised controlled trials (RCTs) have been undertaken examining the efficacy of different therapeutic interventions. The aim of this study was to systematically review the RCTs involving psychological and pharmacological interventions for the treatment of BDD. The literature was searched to June 2015, and studies were included if they were written in English, empirical research papers published in peer-review journals, specifically assessed BDD patients, and involved a RCT assessing BDD symptoms pre- and post-intervention. Nine studies were identified: six involving psychological and three involving pharmacological interventions. Cognitive behaviour therapy, metacognitive therapy and selective serotonin reuptake inhibitors were identified as treatments with potential benefit. The small number of RCTs and the heterogeneity of findings emphasises the need for more high quality RCTs assessing both psychological and pharmacological interventions for BDD.

2015-04-01

Major depressive disorder (MDD) is a serious public health burden and a leading cause of disability. Its pharmacotherapy is currently limited to modulators of monoamine neurotransmitters and second-generation antipsychotics. Recently, glutamatergic approaches for the treatment of MDD have increasingly received attention, and preclinical research suggests that metabotropic glutamate receptor 5 (mGlu5) inhibitors have antidepressant-like properties. Basimglurant (2-chloro-4-[1-(4-fluoro-phenyl)-2,5-dimethyl-1H-imidazol-4-ylethynyl]-pyridine) is a novel mGlu5 negative allosteric modulator currently in phase 2 clinical development for MDD and fragile X syndrome. Here, the comprehensive preclinical pharmacological profile of basimglurant is presented with a focus on its therapeutic potential for MDD and drug-like properties. Basimglurant is a potent, selective, and safe mGlu5 inhibitor with good oral bioavailability and long half-life supportive of once-daily administration, good brain penetration, and high in vivo potency. It has antidepressant properties that are corroborated by its functional magnetic imaging profile as well as anxiolytic-like and antinociceptive features. In electroencephalography recordings, basimglurant shows wake-promoting effects followed by increased delta power during subsequent non-rapid eye movement sleep. In microdialysis studies, basimglurant had no effect on monoamine transmitter levels in the frontal cortex or nucleus accumbens except for a moderate increase of accumbal dopamine, which is in line with its lack of pharmacological activity on monoamine reuptake transporters. These data taken together, basimglurant has favorable drug-like properties, a differentiated molecular mechanism of action, and antidepressant-like features that suggest the possibility of also addressing important comorbidities of MDD including anxiety and pain as well as daytime sleepiness and apathy or lethargy.

Tri-partite complex for axonal transport drug delivery achieves pharmacological effect

Directory of Open Access Journals (Sweden)

Frederickson Martyn

2010-01-01

Full Text Available Abstract Background Targeted delivery of pharmaceutical agents into selected populations of CNS (Central Nervous System neurons is an extremely compelling goal. Currently, systemic methods are generally used for delivery of pain medications, anti-virals for treatment of dermatomal infections, anti-spasmodics, and neuroprotectants. Systemic side effects or undesirable effects on parts of the CNS that are not involved in the pathology limit efficacy and limit clinical utility for many classes of pharmaceuticals. Axonal transport from the periphery offers a possible selective route, but there has been little progress towards design of agents that can accomplish targeted delivery via this intraneural route. To achieve this goal, we developed a tripartite molecular construction concept involving an axonal transport facilitator molecule, a polymer linker, and a large number of drug molecules conjugated to the linker, then sought to evaluate its neurobiology and pharmacological behavior. Results We developed chemical synthesis methodologies for assembling these tripartite complexes using a variety of axonal transport facilitators including nerve growth factor, wheat germ agglutinin, and synthetic facilitators derived from phage display work. Loading of up to 100 drug molecules per complex was achieved. Conjugation methods were used that allowed the drugs to be released in active form inside the cell body after transport. Intramuscular and intradermal injection proved effective for introducing pharmacologically effective doses into selected populations of CNS neurons. Pharmacological efficacy with gabapentin in a paw withdrawal latency model revealed a ten fold increase in half life and a 300 fold decrease in necessary dose relative to systemic administration for gabapentin when the drug was delivered by axonal transport using the tripartite vehicle. Conclusion Specific targeting of selected subpopulations of CNS neurons for drug delivery by axonal

Introduction End of life care guidance for people with dementia is lacking and this has been made more problematic in England with the removal of one of the main end of life care guidelines which offered some structure, the Liverpool Care Pathway. This guidance gap may be eased with the development of heuristics (rules of thumb) which offer a fast and frugal form of decision-making. Objective To develop a toolkit of heuristics (rules of thumb) for practitioners to use when caring for people with dementia at the end of life. Method and analysis A mixed-method study using a co-design approach to develop heuristics in three phases. In phase 1, we will conduct at least six focus groups with family carers, health and social care practitioners from both hospital and community care services, using the ‘think-aloud’ method to understand decision-making processes and to develop a set of heuristics. The focus group topic guide will be developed from the findings of a previous study of 46 interviews of family carers about quality end-of-life care for people with dementia and a review of the literature. A multidisciplinary development team of health and social care practitioners will synthesise the findings from the focus groups to devise and refine a toolkit of heuristics. Phase 2 will test the use of heuristics in practice in five sites: one general practice, one community nursing team, one hospital ward and two palliative care teams working in the community. Phase 3 will evaluate and further refine the toolkit of heuristics through group interviews, online questionnaires and semistructured interviews. Ethics and dissemination This study has received ethical approval from a local NHS research ethics committee (Rec ref: 15/LO/0156). The findings of this study will be presented in peer-reviewed publications and national and international conferences. PMID:26338688

To evaluate the effect of learning styles and study behaviors on preclinical medical students' pharmacology exam scores in a non-Western setting. Grasha-Reichmann Student Learning Study Scale and a modified Study Behavior Inventory were used to assess learning styles and study behaviors of preclinical medical students (n = 87). Logistic regression models were used to evaluate the independent effect of gender, age, learning style, and study behavior on pharmacology success. Collaborative (40%) and competitive (27%) dominant learning styles were frequent in the cohort. The most common study behavior subcategories were study reading (40%) and general study habits (38%). Adequate listening and note-taking skills were associated with pharmacology success, whereas students with adequate writing skills had lower exam scores. These effects were independent of gender. Preclinical medical students' study behaviors are independent predictive factors for short-term pharmacology success.

Pharmacology of human experimental anxiety

Directory of Open Access Journals (Sweden)

Full Text Available This review covers the effect of drugs affecting anxiety using four psychological procedures for inducing experimental anxiety applied to healthy volunteers and patients with anxiety disorders. The first is aversive conditioning of the skin conductance responses to tones. The second is simulated public speaking, which consists of speaking in front of a video camera, with anxiety being measured with psychometric scales. The third is the Stroop Color-Word test, in which words naming colors are painted in the same or in a different shade, the incongruence generating a cognitive conflict. The last test is a human version of a thoroughly studied animal model of anxiety, fear-potentiated startle, in which the eye-blink reflex to a loud noise is recorded. The evidence reviewed led to the conclusion that the aversive conditioning and potentiated startle tests are based on classical conditioning of anticipatory anxiety. Their sensitivity to benzodiazepine anxiolytics suggests that these models generate an emotional state related to generalized anxiety disorder. On the other hand, the increase in anxiety determined by simulated public speaking is resistant to benzodiazepines and sensitive to drugs affecting serotonergic neurotransmission. This pharmacological profile, together with epidemiological evidence indicating its widespread prevalence, suggests that the emotional state generated by public speaking represents a species-specific response that may be related to social phobia and panic disorder. Because of scant pharmacological data, the status of the Stroop Color-Word test remains uncertain. In spite of ethical and economic constraints, human experimental anxiety constitutes a valuable tool for the study of the pathophysiology of anxiety disorders.

Traditional Chinese Medicine-Based Network Pharmacology Could Lead to New Multicompound Drug Discovery

Directory of Open Access Journals (Sweden)

2012-01-01

Full Text Available Current strategies for drug discovery have reached a bottleneck where the paradigm is generally “one gene, one drug, one disease.” However, using holistic and systemic views, network pharmacology may be the next paradigm in drug discovery. Based on network pharmacology, a combinational drug with two or more compounds could offer beneficial synergistic effects for complex diseases. Interestingly, traditional chinese medicine (TCM has been practicing holistic views for over 3,000 years, and its distinguished feature is using herbal formulas to treat diseases based on the unique pattern classification. Though TCM herbal formulas are acknowledged as a great source for drug discovery, no drug discovery strategies compatible with the multidimensional complexities of TCM herbal formulas have been developed. In this paper, we highlighted some novel paradigms in TCM-based network pharmacology and new drug discovery. A multiple compound drug can be discovered by merging herbal formula-based pharmacological networks with TCM pattern-based disease molecular networks. Herbal formulas would be a source for multiple compound drug candidates, and the TCM pattern in the disease would be an indication for a new drug.

Rivera, José O

2014-08-01

This article provides an overview of the pharmacological management of traumatic brain injury (TBI). A basic introduction to key pharmacokinetic and pharmacodynamic principles is used to guide the reader. The goals of the pharmacological management of TBI are explained starting with mild TBI. The main medications used for each medical condition are described with a primary emphasis of effects that may interfere with the role of speech-language pathology (SLP). Some medications may interfere with cognitive, motor, and neuromuscular functions, and others may cause ototoxicity. A basic overview of the pharmacological management of moderate to severe TBI is included because the SLP practitioner may encounter patients with TBI during the recovery phase. The importance of assessment of swallowing evaluations is discussed because the oral route of administration of medications is preferred once the patient is stable.

For children with sickle cell disease (SCD), pain is associated with significant current and future morbidity and mortality. Unfortunately, few evidence-based guidelines exist for the management of pain episodes in children with SCD. To inform empirically based treatment strategies for pain management in pediatric SCD, this review integrates and evaluates the extant literature on psychosocial and pharmacological approaches to the management of pain. Findings reveal a paucity of rigorous investigations of psychosocial and pharmacological pain management interventions in children with SCD. Psychosocial interventions included were primarily cognitive-behavioral in nature, whereas pharmacological approaches targeted non-opioid analgesics (ie, nonsteroidal anti-inflammatory drugs and corticosteroids) and opioid medications (ie, morphine and oxycodone). However, to date there is not a "gold standard" for pain management among children with SCD. Because psychosocial and physiological processes each play a role in the etiology and experience of pain, effective pain management requires multidimensional, comprehensive treatment approaches. Considering the significant impact of pain on functional outcomes and quality of life among children with SCD, additional clinical trials are warranted to ensure that interventions are safe and efficacious.

Cutaneous wounds are among the most common soft tissue injuries and are particularly hard to heal in aging. Caloric restriction (CR) is well documented to extend longevity; pharmacologically, profound rejuvenative effects of CR mimetics have been uncovered, especially metformin (MET), resveratrol (RSV), and rapamycin (RAPA). However, locally applied impacts and functional differences of these agents on wound healing remain to be established. Here, we discovered that chronic topical administration of MET and RSV, but not RAPA, accelerated wound healing with improved epidermis, hair follicles, and collagen deposition in young rodents, and MET exerted more profound effects. Furthermore, locally applied MET and RSV improved vascularization of the wound beds, which were attributed to stimulation of adenosine monophosphate-activated protein kinase (AMPK) pathway, the key mediator of wound healing. Notably, in aged skin, AMPK pathway was inhibited, correlated with impaired vasculature and reduced healing ability. As therapeutic approaches, local treatments of MET and RSV prevented age-related AMPK suppression and angiogenic inhibition in wound beds. Moreover, in aged rats, rejuvenative effects of topically applied MET and RSV on cell viability of wound beds were confirmed, of which MET showed more prominent anti-aging effects. We further verified that only MET promoted wound healing and cutaneous integrity in aged skin. These findings clarified differential effects of CR-based anti-aging pharmacology in wound healing, identified critical angiogenic and rejuvenative mechanisms through AMPK pathway in both young and aged skin, and unraveled chronic local application of MET as the optimal and promising regenerative agent in treating cutaneous wound defects. © 2017 The Authors.

To survey the opinion about various curricular components of Doctor of Medicine (MD) pharmacology curriculum in India by stakeholders, including faculty and students. An online survey was done to evaluate the various curricular components of MD pharmacology curriculum being used in India. A total of 393 respondents including faculty, MD students, and other stakeholders completed the survey. The survey was developed using SurveyMonkey platform and link to survey was E-mailed to stakeholders. The results were expressed as percentages. There was a balanced representation of respondents from various designations, teaching experience, regions, and age groups. Most of the respondents (83%) were aware of the MD pharmacology curriculum. However, they reported that it is more inclined to knowledge domain. About half of respondents (53%) said that animal experiments are being used. The most common teaching methods mentioned are seminars (98.5%), journal clubs (95%), and practical exercises by postgraduates (73%), but there is less use of newer methods (25%) in theory and less of clinical pharmacology exercise (39%) in practical classes. The log books are maintained but not assessed regularly. Internal assessment is sparingly used. The MD pharmacology curriculum needs to be made uniform at the national level and updated to include the newer methods in teaching-learning and assessment. There should be sharing of newer methods at a common platform implemented at the national level.

The genus Psiadia Jacq. ex. Willd. belongs to the Asteraceae family and includes more than 60 species. This genus grows in tropical and subtropical regions, being especially well represented in Madagascar and the Mascarene Islands (La Réunion, Mauritius and Rodrigues). Several Psiadia species have been used traditionally for their medicinal properties in Africa and the Mascarene Islands. Based on traditional knowledge, various phytochemical and pharmacological studies have been conducted. However there are no recent papers that provide an overview of the medicinal potential of Psiadia species. Therefore, the aim of this review is to provide a comprehensive summary of the botany, phytochemistry and pharmacology of Psiadia and to highlight the gaps in our knowledge for future research opportunities. The available information on traditional uses, phytochemistry and biological activities of the genus Psiadia was collected from scientific databases through a search using the keyword 'Psiadia' in 'Google Scholar', 'Pubmed', 'Sciencedirect', 'SpringerLink', 'Web of Science', 'Wiley' and 'Scifinder'. Additionally, published books and unpublished Ph.D. and MSc. dissertations were consulted for botanical information and chemical composition. Historically, species of the genus Psiadia have been used to treat a wide range of ailments including abdominal pains, colds, fevers, bronchitis, asthma, rheumatoid arthritis, skin infections and liver disorders among others. Phytochemical works led to the isolation of flavonoids, phenylpropanoids, coumarins and terpenoids. Furthermore, phytochemical compositions of the essential oils of some species have been evaluated. Crude extracts, essential oils and isolated molecules showed in vitro pharmacological activities, such as antimicrobial, anti-viral, anti-inflammatory, antiplasmodial and antileishmanial activities. Crude extracts of Psiadia dentata and Psiadia arguta have specifically been found to be potentially useful for inhibition

A growing number of drug development studies that include pharmacokinetic evaluations are conducted in regions lacking a specialised pharmacology laboratory. This necessitated the development of an International Pharmacology Specialty Laboratory (IPSL) in Zimbabwe. The aim of this article is to describe the development of an IPSL in Zimbabwe. The IPSL was developed collaboratively by the University of Zimbabwe and the University at Buffalo Center for Integrated Global Biomedical Sciences. Key stages included infrastructure development, establishment of quality management systems and collaborative mentorship in clinical pharmacology study design and chromatographic assay development and validation. Two high performance liquid chromatography instruments were donated by an instrument manufacturer and a contract research organisation. Laboratory space was acquired through association with the Zimbabwe national drug regulatory authority. Operational policies, standard operating procedures and a document control system were established. Scientists and technicians were trained in aspects relevant to IPSL operations. A high-performance liquid chromatography method for nevirapine was developed with the guidance of the Clinical Pharmacology Quality Assurance programme and approved by the assay method review programme. The University of Zimbabwe IPSL is engaged with the United States National Institute of Allergy and Infectious Diseases Division of AIDS research networks and is poised to begin drug assays and pharmacokinetic analyses. An IPSL has been successfully established in a resource-limited setting through the efforts of an external partnership providing technical guidance and motivated internal faculty and staff. Strategic partnerships were beneficial in navigating challenges leading to laboratory development and training new investigators. The IPSL is now engaged in clinical pharmacology research.

David Stewart Koslov

2013-08-01

Full Text Available The vas deferens, a muscular conduit conveying spermatozoa from the epididymis to the urethra, has been used as a model tissue for smooth muscle pharmacological and physiological advancements. Many drugs, notably α-adrenergic antagonists, have effects on contractility and thus normal ejaculation, incurring significant side effects for patients that may interfere with compliance. A more thorough understanding of the innervation and neurotransmitter pharmacology of the vas has indicated that this is a highly complex structure and a model for co-transmission at the synapse. Recent models have shown clinical scenarios that alter the vas contraction. This review covers structure, receptors, neurotransmitters, smooth muscle physiology, and clinical implications of the vas deferens.

There is a need to identify individual treatment success in patients with fibromyalgia (FM) who received non-pharmacological treatment. The present study described responder criteria for multicomponent non-pharmacological treatment in FM, and estimated and compared their sensitivity and specificity. Candidate responder sets were 1) identified in literature; and 2) formulated by expert group consensus. All candidate responder sets were tested in a cohort of 129 patients with FM receiving multicomponent non-pharmacological treatment. We used two gold standards (both therapist's and patient's perspective), assessed at six months after the start of treatment. Seven responder sets were defined (three identified in literature and four formulated by expert group consensus), and comprised combinations of domains of 1) pain; 2) fatigue; 3) patient global assessment (PGA); 4) illness perceptions; 5) limitations in activities of daily living (ADL); and 6) sleep. The sensitivity and specificity of literature-based responder sets (n=3) ranged between 17%-99% and 15%-95% respectively, whereas the expert-based responder sets (n=4) performed slightly better with regard to sensitivity (range 41%-81%) and specificity (range 50%-96%). Of the literature-based responder sets the OMERACT-OARSI responder set with patient's gold standard performed best (sensitivity 63%, specificity 75% and ROC area = 0.69). Overall, the expert-based responder set comprising the domains illness perceptions and limitations in ADL with patient's gold standard performed best (sensitivity 47%, specificity 96% and ROC area = 0.71). We defined sets of responder criteria for multicomponent non-pharmacological treatment in fibromyalgia. Further research should focus on the validation of those sets with acceptable performance.

Walker, Michael J A

2015-11-15

David Triggle's scientific career began as a chemist, went through medicinal chemistry into pharmacology, and finally on to somewhat more philosophical interests in later years. It was a career marked by many contributions to all of those aspects of science. Chief amongst his many contributions, in addition to those in medicinal chemistry, was his work on the drugs known as calcium ion channel blockers or (calcium antagonists). In the calcium ion channel field he was a particularly instrumental figure in sorting out the mechanisms, actions and roles of the class of calcium channel blockers, known chemical and pharmacologically as the dihydropyridines (DHPs) in particular, as well as other calcium blockers of diverse structures. During the course of a long career, and extensive journeys into medicinal chemistry and pharmacology, he published voluminously in terms of papers, reviews, conference proceedings and books. Notably, many of his papers often had limited authorship where, as senior author it reflected his deep involvement in all aspects of the reported work. His work always helped clarify the field while his incisive reviews, together with his role in coordinating and running scientific meetings, were a great help in clarifying and organizing various fields of study. He has had a long and illustrious career, and is wellknown in the world of biomedical science; his contributions are appreciated, and well recognized everywhere. The following article attempts to chart a path through his work and contributions to medicinal chemistry, pharmacology, science, academia and students. Copyright © 2015 Elsevier Inc.

Main Dynamics of the Transition from Industrial Society to Information Society

Directory of Open Access Journals (Sweden)

Yaşar Tonta

2005-12-01

Full Text Available Industrial Society is based on mass production and mass distribution of standardized goods and services. The objective of companies is to reduce the unit cost by producing and distributing the same goods in large quantities cheaper than their competitors. Mass production and mass distribution requires an economic model based on centralization; mechanistical, rigid/hierarchical organizational structures; and traditional education. Companies act on the basis of the logic of “produce, store, and sell”. Information Society on the other hand is an indication of a more complex and richer social structure. The objective of companies is to produce mass customized and personalized goods and services for their customers. The customer can buy a personalized good or service with the best price from anywhere in the world. Called “The Age of Terrific Deal” by Robert B. Reich, Information Society requires an economic model based on personalization; dynamic and flat organizational structures; and customer focused education. Companies must act on the basis of the logic of “sell, produce, and deliver”. This paper discusses the major changes that take place during the transition from Industrial Society to Information Society along with basic dynamics of the Information Society.

DIVERSE POTENTIAL AND PHARMACOLOGICAL STUDIES OF ARGININE

Directory of Open Access Journals (Sweden)

Anju Meshram

2015-09-01

Full Text Available Arginine is metabolically flexible amino acid with major role in protein synthesis and detoxification of ammonia. It is involved in several metabolic pathways for the production of biologically active compounds such as creatine, nitric oxide, ornithine, glutamate, agmatine, citrulline and polyamines. Regarding this all, we review the crucial role of arginine in metabolism, diversified prospective uses and pharmacological applications. Arginine plays an important role in the treatment of tumorigenesis, asthama, gastric, erectile dysfunction, apoptosis, melanoma and congestive heart failure. Ability to produce nitric oxide offers various applications as in the prevention of age and hair loss. It serves as a precursor of creatine with ergogenic potential. The ability to increase endogenous growth hormone makes arginine a preferred supplement for the improvement of physical performance. In the present study details about the pharmacological applications of arginine based on modern scientific investigations have been discussed. There are immense properties hidden in arginine that need to be explored using the scientific investigations to make it beneficial for the medicine and human health. More research is needed to evaluate the role of arginine supplementation on exercise performance and training adaptations in healthy and diseased populations before taking any conclusions.

Mika Sato-Nakai

2017-07-01

Full Text Available Two metabolites (M4 and M1b in plasma and four metabolites (M4, M6, M1a and M1b in faeces were detected through the human ADME study following a single oral administration of [14C]alectinib, a small-molecule anaplastic lymphoma kinase inhibitor, to healthy subjects. In the present study, M1a and M1b, which chemical structures had not been identified prior to the human ADME study, were identified as isomers of a carboxylate metabolite oxidatively cleaved at the morpholine ring. In faeces, M4 and M1b were the main metabolites, which shows that the biotransformation to M4 and M1b represents two main metabolic pathways for alectinib. In plasma, M4 was a major metabolite and M1b was a minor metabolite. The contribution to in vivo pharmacological activity of these circulating metabolites was assessed from their in vitro pharmacological activity and plasma protein binding. M4 had a similar cancer cell growth inhibitory activity and plasma protein binding to that of alectinib, suggesting its contribution to the antitumor activity of alectinib, whereas the pharmacological activity of M1b was insignificant.

Our understanding of whether and/or how ethnicity influences pharmacological response to asthma therapies is still very scarce. A possible explanation for the increased asthma treatment failures observed in ethnic and racial minorities receiving asthma therapies is that some of these groups may have a pharmacogenomic predisposition to either nonresponse or to adverse response with a specific class of drugs. However, the effects of ethnicity on pharmacological response to asthma therapies are also, and mainly, determined by socioeconomic and environmental factors to a varying extent, depending on the ethnic groups. Areas covered: Genetic, socioeconomic and environmental factors that can affect the pharmacotherapeutic responses to asthma medications and their link(s) to race/ethnicity have been examined and critically discussed. Expert opinion: Differences in genetic ancestry are definitely non-modifiable factors, but socioeconomic and environmental disadvantages are all factors that can be modified. It is likely that improved outcomes may be achieved when tailored and multifaceted approaches that include home, school, and clinician-based interventions are implemented. Consequently, it is critical to determine if a clinical intervention programme combined with implementation strategies that attempt to reduce inequalities can reduce asthma disparities, including the influence of ethnicity and race on pharmacological response to asthma therapies.

The pharmacological effects of ethanolic Vitex agnus-castus fruit-extracts (especially Ze 440) and various extract fractions of different polarities were evaluated both by radioligand binding studies and by superfusion experiments. A relative potent binding inhibition was observed for dopamine D2 and opioid (micro and kappa subtype) receptors with IC50 values of the native extract between 20 and 70 mg/mL. Binding, neither to the histamine H1, benzodiazepine and OFQ receptor, nor to the binding-site of the serotonin (5-HT) transporter, was significantly inhibited. The lipophilic fractions contained the diterpenes rotun-difuran and 6beta,7beta-diacetoxy-13-hydroxy-labda-8,14-dien . They exhibited inhibitory actions on dopamine D2 receptor binding. While binding inhibition to mu and kappa opioid receptors was most pronounced in lipophilic fractions, binding to delta opioid receptors was inhibited mainly by a aqueous fraction. Standardised Ze 440 extracts of different batches were of constant pharmacological quality according to their potential to inhibit the binding to D2 receptors. In superfusion experiments, the aqueous fraction of a methanolic extract inhibited the release of acetylcholine in a concentration-dependent manner. In addition, the potent D2 receptor antagonist spiperone antagonised the effect of the extract suggesting a dopaminergic action mediated by D2 receptor activation. Our results indicate a dopaminergic effect of Vitex agnus-castus extracts and suggest additional pharmacological actions via opioid receptors.

Adverse effects of drugs are poorly reported in the literature . The aim of this study was to examine the frequency of the adverse events of antiepileptic drugs (AEDs), in particular carbamazepine (CBZ) and oxcarbazepine (OXC) in patients with neuralgiform pain using the psychometrically tested Liverpool Adverse Events Profile (AEP) and provide clinicians with guidance as to when to change management. The study was conducted as a clinical prospective observational exploratory survey of 161 patients with idiopathic trigeminal neuralgia and its variants of whom 79 were on montherapy who attended a specialist clinic in a London teaching hospital over a period of 2 years. At each consultation they completed the AEP questionnaire which provides scores of 19-76 with toxic levels being considered as scores >45. The most common significant side effects were: tiredness 31.3 %, sleepiness 18.2 %, memory problems 22.7 %, disturbed sleep 14.1 %, difficulty concentrating and unsteadiness 11.6 %. Females reported significantly more side effects than males. Potential toxic dose for females is approximately 1200 mg of OXC and 800 mg of CBZ and1800mg of OXC and 1200 mg of CBZ for males. CBZ and OXC are associated with cognitive impairment. Pharmacokinetic and pharmacodynamic differences are likely to be the reason for gender differences in reporting side effects. Potentially, females need to be prescribed lower dosages in view of their tendency to reach toxic levels at lower dosages. Side effects associated with AED could be a major reason for changing drugs or to consider a referral for surgical management.

Background Many hospitalized adults cannot reposition themselves in their beds. Therefore, they are regularly turned by their nurses, primarily to prevent pressure ulcer formation. Previous research indicates that turning is painful and that patients are rarely pre-medicated with analgesics. Non-pharmacologic interventions may be used to help with this painful procedure. However, no published research was found on the use of non-pharmacologic interventions for turning of hospitalized patients. Objectives 1) to describe patient pain characteristics during turning and their association with patient demographic and clinical characteristics; 2) to determine the frequency of use of various non-pharmacologic interventions for hospitalized adult patients undergoing the painful procedure of turning; and 3) to identify factors that predict the use of specific non-pharmacologic interventions for pain associated with turning. Methods Hospitalized adult patients who experienced turning, the nurses caring for them, and others who were present at the time of turning were asked if they used various non-pharmacologic interventions to manage pain during the turning. Results Of 1395 patients, 92.5% received at least one non-pharmacologic intervention. Most frequently used were calming voice (65.7%), information (60.6%), and deep breathing (37.9%). Critical care patients were more likely to receive a calming voice (OR= 1.66, ppatients. Those reporting higher pain were consistently more likely to receive each of the three interventions (OR=1.01, pturning procedure. The specific interventions used most often are ones that can be initiated spontaneously. These data suggest that patients, nurses, and family members respond to patients’ turning-related pain by using non-pharmacologic interventions. PMID:23688362

Venous thromboembolism (VTE) remains a common problem in critically ill patients. Pharmacologic prophylaxis is currently the standard of care based on high-level evidence from randomized controlled trials. However, limited evidence exists regarding the effectiveness of intermittent pneumatic compression (IPC) devices. The Pneumatic compREssion for preventing VENous Thromboembolism (PREVENT trial) aims to determine whether the adjunct use of IPC with pharmacologic prophylaxis compared to pharmacologic prophylaxis alone in critically ill patients reduces the risk of VTE. The PREVENT trial is a multicenter randomized controlled trial, which will recruit 2000 critically ill patients from over 20 hospitals in three countries. The primary outcome is the incidence of proximal lower extremity deep vein thrombosis (DVT) within 28 days after randomization. Radiologists interpreting the scans are blinded to intervention allocation, whereas the patients and caregivers are unblinded. The trial has 80 % power to detect a 3 % absolute risk reduction in proximal DVT from 7 to 4 %. The first patient was enrolled in July 2014. As of May 2015, a total of 650 patients have been enrolled from 13 centers in Saudi Arabia, Canada and Australia. The first interim analysis is anticipated in July 2016. We expect to complete recruitment by 2018. Clinicaltrials.gov: NCT02040103 (registered on 3 November 2013). Current controlled trials: ISRCTN44653506 (registered on 30 October 2013).

Recent debate suggests Huntington's disease (HD) may be more prevalent than previously reported. In addition, relatively little is known about current disease management. This study aims to provide epidemiological data and describe the pharmacological management of HD in the United Kingdom. A primary care research database was accessed to identify incident and prevalent HD cases between January 1, 2004, and December 31, 2008. Patients with Read codes denoting a definite diagnosis or possible diagnosis, and undiagnosed patients with a positive family history were identified. A subset of patients with a definite diagnosis and prescribed medication indicating symptom onset was also identified. Epidemiological data were estimated. Pharmacological prescriptions to HD patients from 2004 to 2008 were identified, and prescription frequencies were grouped according to the British National Formulary categories. HD incidence estimates ranged from 0.44 to 0.78 per 100,000 person-years, and HD prevalence ranged from 5.96 to 6.54 per 100,000 of the population. Forty-four percent of pharmacological prescriptions targeted the central nervous system. Nearly half of the HD patients were prescribed antidepressants, and over 40% were prescribed analgesics. Although prevalence estimates fell short of figures suggested in recent debate, it is feasible that the true prevalence may be much higher than previously reported. Pharmacological management appears to rely heavily on central nervous system drugs and nutrition support. Many of these drugs are prescribed to HD patients for reasons other than the medication's primary use. Further work is required to evaluate the impact of alternative management strategies, such as therapist intervention, counselling, and organisation support, on the patients' quality of life.

2010-01-01

The current issue of the Journal of Pharmacological and Toxicological Methods (JPTM) focuses exclusively on safety pharmacology methods. This is the 7th year the Journal has published on this topic. Methods and models that specifically relate to methods relating to the assessment of the safety profile of a new chemical entity (NCE) prior to first in human (FIH) studies are described. Since the Journal started publishing on this topic there has been a major effort by safety pharmacologists, toxicologists and regulatory scientists within Industry (both large and small Pharma as well as Biotechnology companies) and also from Contract Research Organizations (CRO) to publish the surgical details of the non-clinical methods utilized but also provide important details related to standard and non-standard (or integrated) study models and designs. These details from core battery and secondary (or ancillary) drug safety assessment methods used in drug development programs have been the focus of these special issues and have been an attempt to provide validation of methods. Similarly, the safety pharmacology issues of the Journal provide the most relevant forum for scientists to present novel and modified methods with direct applicability to determination of drug safety-directly to the safety pharmacology scientific community. The content of the manuscripts in this issue includes the introduction of additional important surgical methods, novel data capture and data analysis methods, improved study design and effects of positive control compounds with known activity in the model.

The flumazenil analogue Ro 16-0154 (Iomazenil), a benzodiazepine partial inverse agonist, has been labelled by halogen exchange to enable SPECT investigations of central benzodiazepine receptors in human brain. The purified 123 I-Ro 16-0154 was found to be stable in rat brain preparations and to be metabolized in rat liver preparations. Its pharmacological properties were comparable to those of flumazenil with the exception of the antagonism of diazepam versus pentylenetetrazol. Biodistribution in rats (1 h p.i.) resulted in a high brain to blood ratio of 16. Clinical studies revealed images of the bezodiazepine receptor density in the brain.

Rzigalinski, Beverly A.; Strobl, Jeannine S.

2009-01-01

The field of nanotechnology is rapidly expanding with the development of novel nanopharmaceuticals that have potential for revolutionizing medical treatment. The rapid pace of expansion in this field has exceeded the pace of pharmacological and toxicological research on the effects of nanoparticles in the biological environment. The development of cadmium-containing nanoparticles, known as quantum dots, show great promise for treatment and diagnosis of cancer and targeted drug delivery, due to their size-tunable fluorescence and ease of functionalization for tissue targeting. However, information on pharmacology and toxicology of quantum dots needs much further development, making it difficult to assess the risks associated with this new nanotechnology. Further, nanotechnology poses yet another risk for toxic cadmium, which will now enter the biological realm in nano-form. In this review, we discuss cadmium-containing quantum dots and their physicochemical properties at the nano-scale. We summarize the existing work on pharmacology and toxicology of cadmium-containing quantum dots and discuss perspectives in their utility in disease treatment. Finally, we identify critical gaps in our knowledge of cadmium quantum dot toxicity, and how these gaps need to be assessed to enable quantum dot nanotechnology to transit safely from bench to bedside.

Molecular and clinical pharmacology of intranasal corticosteroids: clinical and therapeutic implications.

Science.gov (United States)

Derendorf, H; Meltzer, E O

2008-10-01

Intranasal corticosteroids (INSs) are effective treatments for allergic rhinitis, rhinosinusitis, and nasal polyposis. In recent years, increased understanding of corticosteroid and glucocorticoid receptor pharmacology has enabled the development of molecules designed specifically to achieve potent, localized activity with minimal risk of systemic exposure. Pharmacologic potency studies using affinity and other assessments have produced similar rank orders of potency, with the most potent being mometasone furoate, fluticasone propionate, and its modification, fluticasone furoate. The furoate and propionate ester side chains render these agents highly lipophilic, which may facilitate their absorption through nasal mucosa and uptake across phospholipid cell membranes. These compounds demonstrate negligible systemic absorption. Systemic absorption rates are higher among the older corticosteroids (flunisolide, beclomethasone dipropionate, triamcinolone acetonide, and budesonide), which have bioavailabilities in the range of 34-49%. Studies, including 1-year studies with mometasone furoate, fluticasone propionate, and budesonide that evaluated potential systemic effects of INSs in children have generally found no adverse effects on hypothalamic-pituitary-adrenal axis function or growth. Clinical data suggest no significant differences in efficacy between the INSs. Theoretically, newer agents with lower systemic availability may be preferable, and may come closer to the pharmacokinetic/pharmacologic criteria for the ideal therapeutic choice.

Pharmacological treatment and therapeutic perspectives of metabolic syndrome.

Science.gov (United States)

Lim, Soo; Eckel, Robert H

2014-12-01

Metabolic syndrome is a disorder based on insulin resistance. Metabolic syndrome is diagnosed by a co-occurrence of three out of five of the following medical conditions: abdominal obesity, elevated blood pressures, elevated glucose, high triglycerides, and low high-density lipoprotein-cholesterol (HDL-C) levels. Clinical implication of metabolic syndrome is that it increases the risk of developing type 2 diabetes and cardiovascular diseases. Prevalence of the metabolic syndrome has increased globally, particularly in the last decade, to the point of being regarded as an epidemic. The prevalence of metabolic syndrome in the USA is estimated to be 34% of adult population. Moreover, increasing rate of metabolic syndrome in developing countries is dramatic. One can speculate that metabolic syndrome is going to induce huge impact on our lives. The metabolic syndrome cannot be treated with a single agent, since it is a multifaceted health problem. A healthy lifestyle including weight reduction is likely most effective in controlling metabolic syndrome. However, it is difficult to initiate and maintain healthy lifestyles, and in particular, with the recidivism of obesity in most patients who lose weight. Next, pharmacological agents that deal with obesity, diabetes, hypertension, and dyslipidemia can be used singly or in combination: anti-obesity drugs, thiazolidinediones, metformin, statins, fibrates, renin-angiotensin system blockers, glucagon like peptide-1 agonists, sodium glucose transporter-2 inhibitors, and some antiplatelet agents such as cilostazol. These drugs have not only their own pharmacologic targets on individual components of metabolic syndrome but some other properties may prove beneficial, i.e. anti-inflammatory and anti-oxidative. This review will describe pathophysiologic features of metabolic syndrome and pharmacologic agents for the treatment of metabolic syndrome, which are currently available.

The 650th anniversary of the foundation of Charles University (7 April 1348) in Prague has initiated a number of historical surveys of the subjects which has been taught at the University for a longer period of time. The disciplines connected with pharmacotherapy were being developed in an empirical conception at the University from the second half of the 14th century but the beginnings of experimental drug research date as late as the mid-19th century. The present survey of the history of "the sciences of medicaments" therefore attempts to outline in short entries the developmental stages of pharmaceutical and pharmacological investigations in the territory of Bohemia and Moravia in about recent 150 years. The arrangement of data is chronological; in the part covering the second half of the 20th century the research of a predominantly exploratory character (universities and academic institutions and their representatives) and research aimed primarily to innovate medicaments (research institutions of pharmaceutical industry and clinical pharmacology and some of their representatives) are treated separately.

Full Text Available ABSTRACTSpecies of the genus Cordia, Boraginaceae, are widely studied with regard to the various ethnobotanical and ethnopharmacological aspects. They are found principally in tropical and subtropical regions of the American, Asian and African continents, where they occur in various countries. In the genus Cordia, there are many species cultivated for ornamental plants, wood and medicinal applications, where they are extensively utilized by traditional communities. In the last decades, scientific studies of Cordia species have intensified, demonstrating the great interest in phytochemical, biological and pharmacological studies. In this review, we describe the principal botanical aspects, ethnopharmacological information and evaluation of the bioactive and pharmacological properties of Cordia, its phytochemical constituents and the most common classes of secondary metabolites identified. The information reported in this work contributes scientifically to recognizing the importance of the genus Cordia as a target in the search for new biotechnological investments.

Full Text Available Background and objectives: Lippia citrodora commonly known as lemon verbena is a species of flowering plant in the verbena family, native to western South America. With its antioxidant effects, it is mostly used in folk medicine to treat anti-inflammatory diseases, and diseases associated with oxidative stress. This review has presented a summary on L. citordora’s phytochemistry and its pharmacological activities. It will also discuss gaps and challenges needed to be solved. Methods: Electronic database including Web of Science, PubMed, Science Direct and Google Scholar were searched for articles published between 1973 and 2017 regarding the phytochemistry and biological activities of L. citodora. Results: Traditional uses of this plant were specially related to coagulation system, digestive system and brain. Phytochemical investigations identified flavonoids, terpenes, iridois, lignins, phenylethanoid, as the main components of the plant. Antimicrobial, neuroprotective, antinociceptive, anti hyperpropulsive, sedative, anticolitis, anxiolytic, anticonvulsant, antihyperalgesic, and anticancer properties were among the pharmacological activities of L. citriodora. The plant extract and essential oil had also demonstrated high antioxidant activity. Conclusion: Modern pharmacological studies have now validated many traditional uses of L. citrodora. The data reviewed here revealed that this plant is a potential source for the treatment of a wide range of diseases specially inflammatory diseases and neurological dysfunctions. Future human studies are needed for further confirmation of the therapeutic activities of L. citriodora.

In Japan, most women manage labour pain without pharmacological interventions. However, New Zealand statistics show a high percentage of epidural use amongst Asian women. Entonox (a gas mixture of nitrous oxide and oxygen) and pethidine are also available to women in New Zealand. This article investigates how Japanese women in New Zealand respond to the use of pharmacological pain relief in labour. The study was guided by two research questions: (1) How do Japanese women experience and manage labour pain in New Zealand? (2) How do they feel about the use of pharmacological pain relief? Thirteen Japanese women who had given birth in New Zealand were interviewed individually or in a focus group. The conversations were analysed using thematic analysis. Although in Japan very few women use pain relief, nine women received epidural and/or Entonox out of 11 women who experienced labour pain. The contrast between their Japanese cultural expectations and their birth experiences caused some of the women subsequent personal conflict. Japanese women's cultural perspectives and passive attitudes were demonstrated to influence the decision-making process concerning pain relief. It was concluded that understanding Japanese cultural worldviews and approaches to the role of pain in labour would help maternity providers in their provision of appropriate care for Japanese women.
