    No mundo milhares de pessoas sĂŁo perseguidas, humilhadas e sofrem diferentes tipos de violĂȘncia em razĂŁo de sua orientação sexual e identidade de gĂȘnero. Em diferentes paĂ­ses, o algoz Ă© o prĂłprio Estado, que pune a homossexualidade com castigos fĂ­sicos e atĂ© a morte. Reconhecer homossexuais e minorias de gĂȘnero enquanto grupo social para que possam ter a proteção do instituto do refĂșgio Ă© uma das formas de proteger os direitos humanos desses grupos. Mas ainda sĂŁo poucos os paĂ­ses que assim os reconhecem. O Brasil tem avançado nessa questĂŁo, uma vez que a interpretação do Conare- ComitĂȘ Nacional para Refugiados Ă© de que gays, lĂ©sbicas, bissexuais, transexuais e intersexuais pertencem a determinado grupo social. A partir deste contexto, o presente trabalho tem por objetivo defender a tese de que as minorias sexuais e de gĂȘnero devem ser consideradas enquanto grupo social para fins de concessĂŁo de refĂșgio. Para tanto, analisarĂĄ o direito ao refĂșgio a partir da Convenção de 1951, a lei brasileira 9.474/1997 que implementa a Convenção de 51 no paĂ­s e a condição das minorias sexuais e de gĂȘnero enquanto grupo social. Trata-se de um trabalho de revisĂŁo bibliogrĂĄfica, com utilização do mĂ©todo hipotĂ©tico dedutivo, visando confirmar a hipĂłtese central do presente trabalho e responder ao problema primordial da pesquisa: podem as assim consideradas minorias sexuais e de gĂȘnero ser reconhecidas enquanto grupo social para fins de concessĂŁo de refĂșgio

Pharmacology Research & Perspectives published by John Wiley & Sons Ltd, British Pharmacological Society and American Society for Pharmacology and Experimental Therapeutics. α1-adrenoceptor antagonists are widely used for hypertension (eg, doxazosin) and benign prostatic hypertrophy (BPH, eg, tamsulosin). Some antidepressants and antipsychotics have been reported to have α1 affinity. This study examined 101 clinical drugs and laboratory compounds to build a comprehensive understanding of α1-adrenoceptor subtype affinity and selectivity. [3H]prazosin whole-cell binding was conducted in CHO cells stably expressing either the full-length human α1A, α1B, or α1D-adrenoceptor. As expected, doxazosin was a high-affinity nonselective α1-antagonist although other compounds (eg, cyclazosin, 3-MPPI, and ARC239) had higher affinities. Several highly α1A-selective antagonists were confirmed (SNAP5089 had over 1700-fold α1A selectivity). Despite all compounds demonstrating α1 affinity, only BMY7378 had α1D selectivity and no α1B-selective compounds were identified. Phenoxybenzamine (used in pheochromocytoma) and dibenamine had two-component-binding inhibition curves at all three receptors. Incubation with sodium thiosulfate abolished the high-affinity component suggesting this part is receptor mediated. Drugs used for hypertension and BPH had very similar α1A/α1B/α1D-adrenoceptor pharmacological profiles. Selective serotonin reuptake inhibitors (antidepressants) had poor α1-adrenoceptor affinity. Several tricyclic antidepressants (eg, amitriptyline) and antipsychotics (eg, chlorpromazine and risperidone) had high α1-adrenoceptor affinities, similar to, or higher than, α blockers prescribed for hypertension and BPH, whereas others had poor α1 affinity (eg, protriptyline, sulpiride, amisulpiride, and olanzapine). The addition of α blockers for the management of hypertension or BPH in people already taking tricyclic antidepressants and certain antipsychotics may not be beneficial. Awareness of the α-blocking potential of different antipsychotics may affect the choice of drug for those with delirium where additional hypotension (eg, in sepsis) may be detrimental

    The most important goal of customer services is to keep the customer satisfied. However, service resources are always limited and must be prioritized. Therefore, it is important to identify customers who potentially become unsatisfied and might lead to escalations. Today this prioritization of customers is often done manually. Data science on IoT data (esp. log data) for machine health monitoring, as well as analytics on enterprise data for customer relationship management (CRM) have mainly been researched and applied independently. In this paper, we present a framework for a data-driven decision support system which combines IoT and enterprise data to model customer sentiment. Such decision support systems can help to prioritize customers and service resources to effectively troubleshoot problems or even avoid them. The framework is applied in a real-world case study with a major medical device manufacturer. This includes a fully automated and interpretable machine learning pipeline designed to meet the requirements defined with domain experts and end users. The overall framework is currently deployed, learns and evaluates predictive models from terabytes of IoT and enterprise data to actively monitor the customer sentiment for a fleet of thousands of high-end medical devices. Furthermore, we provide an anonymized industrial benchmark dataset for the research community

    Coupling of alpha(1)-Adrenoceptors to ERK1/2 in the Human Prostate

    Introduction: alpha(1)-Adrenoceptors are considered critical for the regulation of prostatic smooth muscle tone. However, previous studies suggested further alpha(1)-adrenoceptor functions besides contraction. Here, we investigated whether alpha(1)-adrenoceptors in the human prostate may activate extracellular signal-regulated kinases (ERK1/2). Methods: Prostate tissues from patients undergoing radical prostatectomy were stimulated in vitro. Activation of ERK1/2 was assessed by Western blot analysis. Expression of ERK1/2 was studied by immunohistochemistry. The effect of ERK1/2 inhibition by U0126 on phenylephrine-induced contraction was studied in organ-bath experiments. Results: Stimulation of human prostate tissue with noradrenaline (30 mu M) or phenylephrine (10 mu M) resulted in ERK activation. This was reflected by increased levels of phosphorylated ERK1/2. Expression of ERK1/2 in the prostate was observed in smooth muscle cells. Incubation of prostate tissue with U0126 (30 mu M) resulted in ERK1/2 inhibition. Dose-dependent phenylephrine-induced contraction of prostate tissue was not modulated by U0126. Conclusions: alpha(1)-Adrenoceptors in the human prostate are coupled to ERK1/2. This may partially explain previous observations suggesting a role of alpha(1)-adrenoceptors in the regulation of prostate growth. Copyright (C) 2011 S. Karger AG, Base

    Recent trends in publication of basic science and clinical research by United States investigators in anesthesia journals

    <p>Abstract</p> <p>Background</p> <p>United States anesthesia research production declined sharply from 1980-2005. Whether this trend has continued despite recent calls to improve output is unknown. We conducted an observational internet analysis to quantify American basic science and clinical anesthesia research output in 14 anesthesia journals with impact factors greater than one at three-year intervals during the past decade.</p> <p>Results</p> <p>American investigators published 1,486 (21.7%) of the total of 6,845 research articles identified in anesthesia journals in 2001, 2004, 2007, and 2010. Approximately two-thirds of all US articles were published in <it>Anesthesiology </it>and <it>Anesthesia and Analgesia</it>. There was a significant correlation (r<sup>2 </sup>= 0.316; P = 0.036) between the number of articles published by American authors in each anesthesia journal and the corresponding journal's impact factor in 2010. Significantly (P < 0.05; Pearson's Chi-square) fewer basic science articles were published in 2007 and 2010 compared with 2001. US clinical research output also declined in 2007 (201; 15.7%) compared with 2001 (266; 19.1%) and 2004, but an increase occurred in 2010 (279; 21.8%, P < 0.05 versus 2007).</p> <p>Conclusions</p> <p>The results indicate that US anesthesia research output continued to decrease from 2001 to 2007. An increase in clinical but not basic science research was observed in 2010 compared with 2007, suggesting that a modest recovery in clinical research production may have begun.</p

    The α1-adrenergic receptors: diversity of signaling networks and regulation

    Get PDF
    The α1-adrenergic receptor (AR) subtypes (α1a, α1b, and α1d) mediate several physiological effects of epinephrineand norepinephrine. Despite several studies in recombinant systems and insightfrom genetically modified mice, our understanding of the physiological relevance and specificity of the α1-AR subtypes is still limited. Constitutive activity and receptor oligomerization have emerged as potential features regulating receptor function. Another recent paradigm is that ÎČarrestins and G protein-coupled receptors themselves can act as scaffolds binding a variety of proteins and this can result in growing complexity of the receptor-mediated cellular effects. The aim of this review is to summarize our current knowledge on some recently identified functional paradigms and signaling networks that might help to elucidate the functional diversity of the α1-AR subtypes in various organs

    Expression and function of G-protein-coupled receptorsin the male reproductive tract

    This review focuses on the expression and function of muscarinic acetylcholine receptors (mAChRs), α1-adrenoceptors and relaxin receptors in the male reproductive tract. The localization and differential expression of mAChR and α1-adrenoceptor subtypes in specific compartments of the efferent ductules, epididymis, vas deferens, seminal vesicle and prostate of various species indicate a role for these receptors in the modulation of luminal fluid composition and smooth muscle contraction, including effects on male fertility. Furthermore, the activation of mAChRs induces transactivation of the epidermal growth factor receptor (EGFR) and the Sertoli cell proliferation. The relaxin receptors are present in the testis, RXFP1 in elongated spermatids and Sertoli cells from rat, and RXFP2 in Leydig and germ cells from rat and human, suggesting a role for these receptors in the spermatogenic process. The localization of both receptors in the apical portion of epithelial cells and smooth muscle layers of the vas deferens suggests an involvement of these receptors in the contraction and regulation of secretion.Esta revisĂŁo enfatiza a expressĂŁo e a função dos receptores muscarĂ­nicos, adrenoceptores α1 e receptores para relaxina no sistema reprodutor masculino. A expressĂŁo dos receptores muscarĂ­nicos e adrenoceptores α1 em compartimentos especĂ­ficos de dĂșctulos eferentes, epidĂ­dimo, ductos deferentes, vesĂ­cula seminal e prĂłstata de vĂĄrias espĂ©cies indica o envolvimento destes receptores na modulação da composição do fluido luminal e na contração do mĂșsculo liso, incluindo efeitos na fertilidade masculina. AlĂ©m disso, a ativação dos receptores muscarĂ­nicos leva Ă  transativação do receptor para o fator crescimento epidermal e proliferação das cĂ©lulas de Sertoli. Os receptores para relaxina estĂŁo presentes no testĂ­culo, RXFP1 nas espermĂĄtides alongadas e cĂ©lulas de Sertoli de rato e RXFP2 nas cĂ©lulas de Leydig e germinativas de ratos e humano, sugerindo o envolvimento destes receptores no processo espermatogĂȘnico. A localização de ambos os receptores na porção apical das cĂ©lulas epiteliais e no mĂșsculo liso dos ductos deferentes de rato sugere um papel na contração e na regulação da secreção.Fundação de Amparo Ă  Pesquisa do Estado de SĂŁo Paulo (FAPESP)Conselho Nacional de Desenvolvimento CientĂ­fico e TecnolĂłgico (CNPq)Universidade Federal de SĂŁo Paulo (UNIFESP) Escola Paulista de Medicina Departamento de FarmacologiaUNIFESP, EPM, Depto. de FarmacologiaSciEL
