مقدمه: سندرم متابولیک به دلیل ارتباط آن با دیابت نوع 2 و بیماری های قلبی ـ عروقی بسیار مورد توجه است. یافته های متناقضی در مورد نقش هورمون های جنسی در پاتوژنز سندرم متابولیک وجود دارد. هدف از مطالعه ی حاضر، بررسی ارتباط تستوسترون تام، نمایه ی تستوسترون آزاد و shbg سرم با بروز سندرم متابولیک بر اساس دو معیار idf و atp iii بود. مواد و روش ها: از میان جمعیت شرکت کننده در مطالعه ی قند و لیپید تهران...
Meat goat enterprise efficiency was estimated using an input distance function (IDF) by applying stochastic production frontier techniques for the southeastern U.S. region. We found increasing returns to scale and scope economies for southeastern U.S. meat goat enterprises. Mean technical efficiency was 0.81. Our results suggest southeastern U.S. meat goat enterprises can be scale efficient if ...
BACKGROUND Metabolic syndrome (MetS) has been related to type 2 diabetes and cardiovascular diseases. Different criteria for diagnosis of MetS have been recommended, but there is no agreement about which criteria are best to use. The aim of the present study was to investigate agreement between the National Heart, Lung, and Blood Institute, American Heart Association (NHLBI/AHA) and the Interna...

In this work, the multifractal properties of hourly rainfall data recorded at a location in Southern Spain have been related to the scale properties of the corresponding intensity–duration–frequency (IDF) curves. Four parametric models for the IDF curves have been fitted to the quantiles of rainfall obtained using the generalized Pareto frequency distribution function with the extreme data seri...
For bounded datasets such as the TREC Web Track (WT10g) the computation of term frequency (TF) and inverse document frequency (IDF) is not difficult. However, when the corpus is the entire web, direct IDF calculation is impossible and values must instead be estimated. Most available datasets provide values for term count (TC) meaning the number of times a certain term occurs in the entire corpu...
The present work was conducted to investigate the coconut residue (CR) left after the extraction of coconut milk by subjecting it to physical treatments. Water-washed samples as well as the original samples were analyzed for their chemical composition, soluble dietary fiber (SDF), insoluble dietary fiber (IDF) and total dietary fiber (TDF), and measurements were based on dry matter. Fractionate...
The International Diabetes Federation Taskforce on Epidemiology and Prevention of Diabetes convened a consensus working group of diabetologists, endocrinologists, surgeons and public health experts to review the appropriate role of surgery and other gastrointestinal interventions in the treatment and prevention of Type 2 diabetes. The specific goals were: to develop practical recommendations fo...
