PURPOSE To evaluate the role of Doppler ultrasonography (DUS) in diagnosing pediatric testicular torsion (TT), and its diagnostic accuracy, and helping clinicians increase specificity and decrease negative exploration rates. MATERIALS AND METHODS We performed a retrospective study of all consecutive patients with acute testicular symptoms referring to our pediatric emergency department (ED) f...

based on the date obtained through food consumption surveys conducted by the institute of nutrition and food technology research (during 1991-95), the dietary quality of seven provinces (eastern azerbaijan, isfahan, tehran, khorasan, khouzestan, sistan-baluchestan and fars) was assessed. using allowances figures for developing countries, single value nutrient density (s.v.n.a.) was designed for...

Bcl-2/E1B 19-kDa interacting protein 3 (BNIP3) is a proapoptotic protein whose expression level is often low in colorectal cancer (CRC) cells due to the BNIP3 gene promoter DNA methylation by DNA methyltransferase (DNMT). It is known that chemotherapy and radiotherapy suppress CRC through inducing tumor apoptosis. However, the molecular mechanisms underlying chemotherapy and radiotherapy-induce...

Background: Obesity is largely responsible for the growing incidence and prevalence of diabetes, cardiovascular and renal diseases. Current strategies to prevent and treat obesity and its consequences have been insufficient to reverse the ongoing trends. Lifestyle modification or pharmacological therapies often produce modest weight loss which is not sustained and recurrence of obesity is frequ...
