The neuropeptide transmitter cocaine- and amphetamine-regulated transcript (CART) inhibits food intake and is expressed by both vagal afferent and hypothalamic neurons. Here we report that cholecystokinin (CCK) regulates CART expression in rat vagal afferent neurons. Thus, CART was virtually undetectable after energy restriction for 24 h, but administration of CCK to fasted rats increased CART ...
Recent study has indicated that cocaine-amphetamine-regulated transcript (CART) is an anorectic chemical in the brain. In the present study, we examined the hypothesis that CART may act in the central nervous system to alter gastric function. Food consumption, gastric acid secretion, and gastric emptying were measured after injection of CART into the cerebrospinal fluid in 24-h fasted Sprague D...
Cocaine- and amphetamine-regulated transcript (CART) is a neuropeptide that plays neuroprotective roles in cerebral ischemia and reperfusion (I/R) injury in animal models or oxygen and glucose deprivation (OGD) in cultured neurons. Recent data suggest that intranasal CART treatment facilitates neuroregeneration in stroke brain. However, little is known about the effects of post-treatment with C...
OBJECTIVES To compare virological effectiveness in patients who continued on a virologically successful first-line boosted protease inhibitor (PI)-containing combination antiretroviral therapy (cART) regimen or who switched to a PI-free cART including efavirenz, nevirapine or abacavir. METHODS From the French Hospital Database on HIV, we selected 439 patients with undetectable viral load (VL)...
برآورد مشخصه های کمی جنگل در سطوح وسیع بااستفاده از داده های ماهواره ای اهمیت فراوانی در مدیریت پایدار جنگل دارد. هدف از این پژوهش، بررسی امکان برآورد برخی مشخصه های کمی جنگل بااستفاده از تصاویر سنجنده aster در جنگل شصت کلاته گرگان است. برای این منظور تعداد 112 قطعه نمونه زمینی مربعی به مساحت 09/0 هکتار به روش خوشهای تصادفی در واحدهای همگن ازنظر تیپ درختی و جهت دامنه پیاده شد و مشخصه های حجم، ...
رانش زمین یکی از بلایای طبیعی می باشد که هر ساله خسارات مالی و جانی زیادی را به بار می آورد. با توجه به تاثیرات سویی که زمین لغزش ها بر سکونت گاه های روستایی و شهری و منابع طبیعی دارند شناسایی مناطق مستعد وقوع زمین لغزش امری بسیار ضروری برای جلوگیری از چنین خسارت هایی بشمار می آید. هدف این مقاله پیش بینی شدت رانش زمین در منطقه مورد مطالعه می باشد، با استفاده از درخت رگرسیون در محیط gisمی باشد. ...
BACKGROUND World-wide, the notable expansion of HIV/AIDS treatment programs in resource-limited settings has lead to an increasing number of patients in need of second-line cART. To adequately address and prepare for this scenario, critical assessments of the outcomes of second-line cART are particularly relevant in settings where monitoring strategies may be inadequate. We evaluated virologic ...
BACKGROUND This paper focuses on the creation of a predictive computer-assisted decision making system for traumatic injury using machine learning algorithms. Trauma experts must make several difficult decisions based on a large number of patient attributes, usually in a short period of time. The aim is to compare the existing machine learning methods available for medical informatics, and deve...
BACKGROUND Although modern combination antiretroviral therapy (cART) regimens are better tolerated and less complex than earlier treatments, regimen modification or discontinuation remains a concern. METHODS We studied HIV Outpatient Study (HOPS) participants who initiated the first or second cART regimens during: 1996-1999, 2000-2003, 2004-2007, and 2008-2011. We analyzed regimen durability ...
BACKGROUND Before the introduction of combination antiretroviral therapy (CART), neurological disease correlated with cerebrospinal fluid (CSF) levels of human immunodeficiency virus (HIV) RNA. OBJECTIVE To investigate the relationships among HIV RNA levels, immune activation markers, and neurological status in patients receiving CART. DESIGN Multicenter cohort study. SETTING Academic neu...
