Background—Macrophage activation plays a crucial role in regulating adipose tissue inflammation and is a major contributor to the pathogenesis of obesity-associated cardiovascular diseases. On various types of stimuli, macrophages respond with either classic (M1) or alternative (M2) activation. M1and M2-mediated signaling pathways and corresponding cytokine production profiles are not completel...
MicroRNAs (miRNA) are a novel class of small noncoding single-stranded RNA molecules that regulate gene expression. There is increasing evidence of their importance in polycystic ovary syndrome (PCOS). The objective was to determine if miRNA-93 and miRNA-223 are differentially expressed in the circulation of women with PCOS compared to age matched women. A case-control study comparing women wit...
Background: Air pollution is one of the disadvantages of unsustainable development cause to short and long term sanitary effects without consideration of environment in addition to destruction of environment. Therefore, the present research was conducted with the purpose of quantifying and estimating of health endpoints related to SO2 pollutants in six cities (Tehran, Mashhad, Isfahan, Shiraz a...
Background and purpose: In the past two decades, epidemiological studies have shown that outdoor air pollution lead to increase in respiratory symptoms, cardiovascular diseases, chronic bronchitis and mortality. This study aimed to estimate AQI index and the risk of cardiovascular and respiratory diseases and premature mortality caused by PM10, PM2.5 and SO2 in Yazd, 2013-2014. Materials and...
mTOR is a serine/threonine kinase that regulates cell growth, metabolism, proliferation, and survival. mTOR complex-1 (mTORC1) and mTOR complex-2 (mTORC2) are critical mediators of the PI3K-AKT pathway, which is frequently mutated in many cancers, leading to hyperactivation of mTOR signaling. Although rapamycin analogues, allosteric inhibitors that target only the mTORC1 complex, have shown som...
زمینه و هدف: آلودگی هوا یک ازعمده ترین مشکلات کلانشهرها می باشد، که آثار مخرب زیادی بر سلامت انسان و محیط زیست داشته و باعث به وجود آمدن بیماری های مختلف از جمله بیماری های قلبی عروقی می شود. بنابراین مطالعه حاضر با هدف کمیسازی و برآورد اثرات بهداشتی منتسب به آلاینده co در کلانشهر تهران طی یک دوره پنج ساله با استفاده از مدل airq انجام شد. روش کار: این مطالعه از نوع توصیفی مقطعی می باشد. ...
مشکلات بهداشتی مرتبط با مواجهه آلودگی هوا اغلب موجب تحمل هزینه ها در مراقبت بهداشتی، غیبت از کار و از دست دادن شغل، موارد حادتری مانند ناتوانی های دائمی و مرگ می شود. شهر تبریز به دلیل وجود بسیاری از کارخانجات بزرگ صنعتی در آن و ورود بیش از ظرفیت خودروهای جدید به چرخه تردد شهری، به عنوان یکی از آلوده ترین شهرهای کشور به شمار می رود. لذا در این مطالعه سعی بر این است که کمّی سازی و مقایسه اثرات ب...
background & objectives:airq software proved to be a valid and reliable tool to estimate the potential short term effects of air pollution. in this study the airq2.2.3 model was used to evaluate adverse health effects caused by nitrogen dioxide(no2) exposure in ahvaz during 2009. materials & methods:the airq,developed by the world health organization (who) to predict health endpoints a...
introduction: air pollution due to particulate matter is a major environmental and health issue in all regions of the world. the aim of this study was to investigate the health impacts of pm10 (particulate matter with an aerodynamic diameter ≤10μm) in khorramabad city, iran in 2014. materials and methods: in this study, pm10 sampling was conducted by a high-volume sampler at flow rate of 1.1-1....
Underage drinking is a major problem at American colleges, but little is known about the extent of alcohol use in different student groups, in different colleges, and in states with different control policies. We used data from the 2001 and 3 previous Harvard School of Public Health College Alcohol Studies that compared responses of underage students with those of their 21–23-year-old peers. Un...
