IntroductIon: Lipofilling is gaining more and more popularity in plastic surgery. However, currently the tumorigenicity and angiogenic properties of lipoaspirates for correction of volume defects after breast conserving therapy, is discussed controversially. To assess the safety of lipotransfer into remaining breast tissue, the interaction of primary adipose derived stem cells (ADSC) and mammar...

This paper describes our speech enhancement and recognition systems developed for the Reverberation Challenge 2014. To enhance the noisy and reverberant speech for human listening, besides using conventional methods such as delay and sum beamformer and late reverberation reduction by spectral subtraction, we also studied a novel learning-based speech enhancement. Specifically, we train deep neu...

BACKGROUND/AIMS Semicircular lipoatrophy (SL) is an idiopathic condition characterized by atrophy of subcutaneous fatty tissue. Although several studies have suggested a possible association between SL and occupational exposure to power frequency magnetic fields (MF), no mechanism has been proposed so far that explains an influence of these fields on adipogenesis. METHODS The study investigat...

سابقه و هدف: ورود گونه­­ های ماهی مهاجم دراکوسیستم ­های آبی، سبب بروز انواع اثرات منفی اکولوژیکی اقتصادی-اجتماعی می ­­شود. اولین گام در تجزیه تحلیل مخاطرات ناشی از گونه­ غیر­بومی، شناسایی خطر است بر این اساس ابزارهای متعددی برای ارزیابی خطرات تهاجمی غیربومی به منظور پشتیبانی تصمیم گیرندگان گونه ­­ها ایجاد شده است. هدف پژوهش قدرت تیلاپیای شکم قرمز (Coptodon zillii) حوضه آبریز تالاب شادگان (حوضه‌...

The 1,9-dimethylmethylene blue (DMMB) assay is widely used to quantify sulfated glycosaminoglycan (sGAG) contents of engineered tissues, culture media, tissue samples and bodily fluids, but the assay is subject to interference from polyanions such as hyaluronic acid (HA), DNA and RNA. We examined whether specific combinations of dye pH and absorbance wavelength could minimize non-sGAG artifacts...
