PURPOSE Although cigarette smoking and alcohol use are known risk factors for squamous cell carcinoma of head and neck (SCCHN), only a few exposed individuals develop this disease, suggesting an individual susceptibility. In this study, we investigated the associations between genetically determined DNA repair capacity (DRC) for removing tobacco-induced DNA adducts and risk of SCCHN and tumor c...
The Distributed Resource Controller (DRC) technology described in this paper provides a novel approach to interfacing applications with emerging network mechanisms to deliver Quality of Service (QoS) and controlling network resource utilization. DRC aims to unify network services (e.g., Diffserv, Intserv, and ATM) and application QoS provisioning by introducing a middleware system and a set of ...
1 Dry distillers grains improved gain and efficienicy relative to corn. Heifers supplemented daily consumed more hay and gained faster, but were not more efficient than those supplemented three times weekly. Summary An experiment was conducted with 120 crossbred heifers to determine the value of dry distillers grains (DDG) in high-forage diets, and to evaluate the effect of supplementing daily ...
Imported malaria threatens control and elimination efforts in countries that have low rates of transmission. In 2010, an outbreak of Plasmodium falciparum malaria was reported among United Nations peacekeeping soldiers from Guatemala who had recently returned from the Democratic Republic of the Congo (DRC). Epidemiologic evidence suggested that the soldiers were infected in the DRC, but local t...
استان خراسان رضوی با وسعتی بیش از 127 هزار کیلومتر مربع و جمعیتی حدود 6 میلیون نفر و با آب و هوای گوناگون، از امکان های بالقوه بسیار بالایی برای گسترش کشاورزی و بخصوص باغبانی برخوردار است. با توجه به سهم قابل توجه بخش کشاورزی از صادرات غیر نفتی، شناسایی مزیت های نسبی این بخش در مناطق و استان های کشور برای برنامه ریزی های اقتصادی بسیار ضروری می باشد. بر این اساس مزیت نسبی میوه های هسته دار شامل،...
امروزه با توجه به محدودیت منابع تولید موجود در کشور، استفاده از فناوری‌های نوین نقش مهمی در صرفه‌جویی مصرف نهاده‌ها، افزایش بهره‌وری و بهبود مزیت نسبی در تولید محصولات کشاورزی دارد. در این راستا، زیست فناوری از اهمیت ویژه‌ای برخوردار است. لذا با توجه به اهمیت موضوع و فقدان مطالعه‌ای در زمینه اثر به کارگیری فناوری زیستی در مزیت نسبی تولید محصولات کشاورزی، تحقیق حاضر با هدف تعیین شاخص‌های مزیت نس...
Background & Aims: Cystography with contrast and cystography with radionuclide are two common methods for diagnosis of urinary reflux. This study compared two methods direct radionuclide cystography (DRC) with contrast voidingcystography (VCUG). Materials & Methods: This study was conducted for 12 months on children with urinary tract infection )age: 2 months-15 years) whom referred to nephrol...
Ten ruminally cannulated heifers (BW = 416 kg; SD = 24) were used to test the effect of the form and frequency of supplemental energy on forage DMI and digestibility. Five treatments were arranged in a replicated, 5 x 4 Latin rectangle (n = 8), and included no supplement (control), dry-rolled corn (DRC) fed daily, DRC fed on alternate days (DRC-A), dried distillers grains plus solubles (DDGS) f...
We conducted two experiments to determine the feeding value and effects on diet digestibilities, passage rates, and ruminal metabolism of wheat middlings (WM) fed as a replacement for either the concentrate or roughage components of finishing diets of steers. In Exp. 1, 120 medium-framed steers were blocked by weight and randomly allocated to one of six treatments of high-concentrate diets: con...
Magnesium (Mg) is required for maintenance of genomic stability; however, data on the relationship between dietary Mg intake and lung cancer are lacking. In an ongoing lung cancer case-control study, we identified 1139 cases and 1210 matched healthy controls with data on both diet and DNA repair capacity (DRC). Dietary intake was assessed using a modified Block-NCI food frequency questionnaire ...
