Objective(s) Bupropion is an atypical antidepressant that is widely used in smoke cessation under FDA approval. The study of synaptic effects of bupropion can help to finding out its mechanism(s) for stopping nicotine dependence. In this study the effects of perinatal bupropion on the population spike (PS) amplitude of neonates were investigated. Materials and Methods Hippocampal slices were...

آلودگی هوا یکی از مهمترین مشکلات زندگی شهری و شهرهای پرجمعیت است. از جمله مسائل مهم برای کاهش و مقابله با این مشکل، برآورد و تخمین میزان آلودگی هواست. از سنجنده‌ها با توجه به نوع کاربرد آن‌ها می‌توان برای این کار استفاده کرد. معمول‌ترین این سنجنده‌ها، سنجنده مودیس می‌باشد که بر روی دو ماهواره ترا و آکوا نصب شده است. سنجنده مودیس به علت تعداد باندهای طیفی زیاد، محدوده باندهای طیفی باریک، تصویربر...

زمینه و هدف: امروزه زندگی افراد به خاطر آلاینده های متعدد وارد شده به اتمسفر ناشی از اقدامات انسانی و فعالیت های بیولوژیکی در معرض خطر است. از دیدگاه بهداشت عمومی ذرات معلق یکی از آلاینده های اصلی هوا می باشد. هدف از این پژوهش ارزیابی روش های میان­یابی مکانی جهت تعیین غلظت سطحی ذرات معلق PM10و PM2.5 در شهر سبزوار و در نتیجه، انتخاب مناسب ترین روش میان­یابی...

BACKGROUND Single-nucleotide polymorphisms (SNPs) in the TNFAIP3, IFIH1, and IRF5 genes have been associated with several auto-inflammation diseases, while the susceptibility between these genes and idiopathic inflammatory myopathies (IIMs) were not reported. This study aimed to investigate whether TNFAIP3, IFIH1, and IRF5 gene polymorphisms confer susceptibility for the IIMs in Chinese Han pop...

We construct orthogonal double covers of Kn,n by Pm+1 ∪∗ Sn−m, where n and m are integers, 2 ≤ m ≤ 10, m ≤ n and Pm+1 ∪∗ Sn−m is a tree obtained from the path Pm+1 with m edges and a star Sn−m with n − m edges by identifying an end-vertex of Pm+1 with the center of Sn−m.

This article empirically demonstrates the use of fine resolution satellite-based aerosol optical depth (AOD) to develop time and space resolved estimates of ambient particulate matter (PM) ≤2.5 µm and ≤10 µm in aerodynamic diameters (PM(2.5) and PM(10), respectively). AOD was computed at three different spatial resolutions, i.e., 2 km (means 2 km × 2 km area at nadir), 5 km, and 10 km, by using...

BACKGROUND The effects of airborne particulate matter (PM) are a major human health concern. In this panel study, we evaluated the acute effects of exposure to PM on peak expiratory flow (PEF) and wheezing in children. METHODS Daily PEF and wheezing were examined in 19 asthmatic children who were hospitalized in a suburban city in Japan for approximately 5 months. The concentrations of PM les...

In the present work, annual time series of traffic related pollutants (CO and PM(10)) were considered for frequency analysis (Fourier series) with the aim to understand the underlying physical processes and the influence of emission sources on the variability of the air pollutant concentrations. Several urban traffic and suburban background air quality stations located in Porto metropolitan are...
