Influence of formation of surface nano/ultrafine structure using deep rolling on plasma nitriding and tribological properties of the AISI 316L stainless steel was investigated. Initially, the deep rolling process was carried out on the bar-shaped specimens at 15 cycles with 0.2 mm/s longitudinal rate and 22.4 rpm bar rotation. Then, plasma nitriding treatment was applied on the as-received...

wetability of biocompatible polymers can be improved by plasma surface modification. the purpose of this study was to surface modify an experimental poly (dimethylsiloxane) rubber (pdms) material in order to improve its wetability and biocompatibility. surface properties of the pdms were characterized using contact angles measurement for wetability analysis. samples of experimental silicone rub...

The present study investigated the possible protective effect of Helicteres isora (Sterculiaceae) bark extracts on certain biochemical markers in streptozotocin (STZ)-induced diabetes in rats. STZ treatment (60 mg/kg/i.p) caused a hyperglycemic state that led to various physiological and biochemical alterations. Blood levels of glucose, urea, uric acid and creatinine, plasma levels of albumin a...

Plasma nitriding is a plasma-activated thermochemical method widely used to increase the fatigue strength, hardness and wear resistance of low-alloy steels. In this work, new structure consisting hollow cathode metal plate can produce discharge heat workpiece by radiation. This principle perform source plasma (HCSPN). Herein, 42CrMo steels were treated conventional (CPN) HCSPN treatments. The n...

the pharmacokinetics of levofloxacin following its single intramuscular administration (3 mg/kg) was investigated in six male buffalo calves. peak plasma level of 2.95 ± 0.13μg/ml was observed at 1 h and the drug level above mic90  in plasma was detected up to 12 h of administration. the bioavailability was 68.1 ± 5.4% and levofloxacin was bound to the plasma proteins to the extent of 19.1 ± 1....

The pharmacokinetic parameters of ceftazidime, a third generation cephalosporin, were investigated in six buffalo calves after single intravenous (IV) and intramuscular (IM) administration at a dose rate of 10 mg/kg body weight. Ceftazidime concentrations in plasma and urine were determined by microbiological assay. Ceftazidime disposition was best fitted by a two-compartmental and a one-compar...
