background: considering the increasing incidence of coronary artery stenosis and its related complications, the importance of its etiology and inconsistent reports we aimed to determine the relationship between oxysterol, serum levels and severity of coronary atherosclerosis and effect of statins on oxysterol.  methods: a total of 85 patients referred to taleghani hospital, tehran, iran during ...

human alpha 1-antitrypsin (aat) cdna was obtained from hepg2 cell lines. after pcr and construction of expression vector ppiczα-aat, human aat was expressed in the yeast pichia pastoris (p.pastoris) in a secretary manner and under the control of inducible alcohol oxidase 1 (aox1) promoter. the amount of aat protein in medium was measured as 60 mg/l 72 hr after induction with methanol. results i...

gastro-esophageal reflux disease (gerd) regularly occurs when stomach acid moves up from the stomach into the esophagus. gerd might be associated with chronic asthma symptoms such as coughing and breathlessness. according to several studies on children and adults, gerd is proven to have a close relationship with asthma.  medication treatment via proton-pump inhibitors (ppis), such as omeprazole,...

sodium-glucose co-transporter 2 (sglt2) inhibitors are a new glucose-lowering therapy for t2dm with documented benefits on blood glucose, hypertension, weight reduction and long term cardiovascular benefit. they have an inherent osmotic diuretic effect and lead to some volume loss and possible dehydration. there is some concern about the safety of using sglt2 inhibitors in muslim type 2 diabete...

The initiation of corrosion can be triggered by defects in the adsorbed layer organic inhibitors. A detailed knowledge intermolecular forces between inhibitor molecules and interfacial bonding will decisive to unravel mechanisms driving initiation. In this work, layers 2-mercapto-5-methoxybenzimidazole (SH-BimH-5OMe) 5-amino-2-mercaptobenzimidazole (SH-BimH-5NH 2 ) were compared regarding their...

Abstract Scale formation is one of the major issues in petroleum industry. The development these scale layers could result production losses and equipment instability because pipeline blockage, energy leakage, corrosion acceleration severe accidents which will impact safety process. utilization chemical inhibitors (SIs) considered an economical successful route for prevention. Two main componen...

the organic deposition particularly asphaltenes has many detrimental effects on the oil industries, such as plugging in pipelines, wellbore and facilities and subsequently, considerable reduction in well productivity.asphaltenes are the most polar fractions, which they have been dispersed as colloidal clusters in crude oil. the accumulation of these clusters lead to the flocculation of colloids...
