Severe alpha1-antitrypsin (AAT) deficiency predisposes to emphysema development. Highly variable rates of decline in lung function are reported in PiZZ individuals. The annual decline in forced expiratory volume in one second (FEV1; delta FEV1) was analysed in relation to smoking status in a cohort of 608 adult PiZZ individuals included in the Swedish national AAT deficiency register. Delta FEV...

BACKGROUND We aimed to evaluate the incidence of type 1 diabetes mellitus in children <15 years of age (yr) in the Auckland region (New Zealand) over 20 years (1990-2009). METHODS We performed a retrospective review of all patients <15 yr diagnosed with type 1 diabetes, from an unselected complete regional cohort. RESULTS There were 884 new cases of type 1 diabetes, and age at diagnosis ros...

شاخص فرسایندگی باران مهمترین عامل تاثیرگذار بر فرسایش خاک است.این پژوهش با هدف تعیین تغییرات مکانی و زمانی انرژی فرسایندگی باران در جنوب غرب ایران انجام شده‌است. خصوصیات بیش از 10000 رگبار مربوط به 27 ایستگاه سینوپتیک در جنوب غرب ایران مورد استفاده قرار گرفت و انژری جنبشی (E) و حداکثر شدت بارندگی 30 دقیقه‌ای (I30) رگبارها محاسبه ومتوسط شاخص فرسایندگی ماهیانه و سالیانه برای کلیه ایستگاه‌ها تعیین...

Mixed livestock grazing can offer an alternative management system for rearing dairy replacement heifers (Bos taurus). A 2-yr study was conducted during 2009 (yr 1) and 2010 (yr 2) to determine the effects of co-grazing Holstein heifers under rotational stocking with Boer × Kiko goats on animal performance, pasture DM yield, and botanical composition. Each year, 24 heifers (134 ± 6 d of age and...

Background: Human is exposed to radiation in their environment with or without their consent and the exposure to natural background radiation is an unpreventable event on earth. Materials and Methods: An in situ assessment of the indoor and outdoor background radiation in Akwanga and Keffi towns of Nasarawa state Nigeria was carried out using a halogen-quenched Geiger Muller (GM) detector (Insp...

Exposure to radiation from different types of television sets was measured to ascertain the levels of hazards posed to the human biological system. Measurement of the annual radiation dose hazards was performed using a halogen-quenched GM tube with thin mica end window having a density of 1.5 mg/cm2, effective window diameter of 0.360 inch and side wall of 0.012 inch thick. The GM tube was plac...

High Mountain Asia hosts the largest glacier concentration outside the polar regions. These glaciers are important contributors to streamflow in one of the most populated areas of the world. Past studies have used methods that can only provide regionally-averaged glacier mass balances to assess the High Mountain Asia glacier contribution to rivers and sea level rise. Here we compute the mass ba...
