abstract distal pancreatectomy has been a standard technique for pancreatic body and tail lesions for years ago. recently, it is being performed laparoscopically in a perfect manner. there are two common methods for this procedure. one is distal pancreatectomy with splenectomy and the other is distal pancreatectomy with spleen preservation. in patients with splenic vessels involvement, it is no...
background due to a recent alarming increase in the number of hiv-hcv co-infected patients in romania. objectives a cross sectional study was conducted to assess the baseline predictors of liver disease evolution. patients and methods 83 hiv-hcv co-infected patients, untreated for hcv infection, were evaluated for viral replication, liver fibrosis (estimated by a noninvasive marker - fib4), and...
background: in the recent years nanostructured materials have been the focus of researches due to their wide-spread possibilities to provide new shapes and structures for some materials. microemulsions can provide uniform nano-sized droplets for templating. microemulsions are isotropic, thermodynamically-stable systems of oil, water and surfactant with a 20-200 nm droplet size. they can be prep...
در این مطالعه، عملکرد دو سیستم اکسیداسیون شیمیایی پیشرفته و یک سیستم بیولوژیکی برای حذف آموکسی سیلین در فاضلاب های سنتزیدر غلظت های مشابه با موارد صنعتی مورد بررسی قرار گرفته شدند. مطالعه انجام شده دارای سه بخش متفاوت اکسیداسیون با ازن و اشعه uv، اکسیداسیون با استفاده از نانو فتوکاتالیست tio2 و استفاده از بیوراکتور هوازی لجن فعال با جداکننده های فیزیکی می باشد. در هر بخش، متغیر های متفاوتی متنا...
in this research, the effects of the addition of powdered activated carbon (pac) into the aeration zone of an activated-sludge (as) system for treating tehran oil refinery effluent, was investigated during more than 12 months in a pact pilot-scale model. besides the evaluation of organics removal efficiency and determination of basic design factors kinetic coefficients, a series of experiments ...
septicemia in neonates is the commonest cause of mortality. early recognition and diagnosis of neonatal sepsis remains a challenge because of the variable and nonspecific clinical presentation. the laboratory criteria are often non specific and not fully reliable. the objective of this review is to highlight the various hematological and biological markers of neonatal sepsis. we searched pubmed...
in recent years, demand for biological sensors which are capable of fast and accurate detection of minor amounts of pathogens inreal‑time form has been intensified. acoustic wave (aw) devices whose performance is determined by mass sensitivity parametersand quality factor are used in biological sensors as platforms with high quality. yet, current aw devices are facing many challengessuch as the...
