Following intravenous administration, the elimination half life (t(1/2 beta)), volume of distribution (Vd((area))) and total body clearance were 2.69 +/- 0.14 h, 1.43 +/- 0.08 L kg(-1) and 371.2 +/- 11.2 ml kg(-1) h(-1), respectively. Following intramuscular administration, the absorption half life (t(1/2ka)) was 0.83 +/- 0.20 h. The systemic bioavailability (F) of moxifloxacin in buffalo calves was 80.0 +/- 4.08%. Urinary excretion of moxifloxacin was less than 14% after

24 h of administration of drug. In vitro binding of moxifloxacin to plasma proteins of buffalo calves was 28.4 +/- 3.77%. From the data SNX-5422 of surrogate markers (AUC/MIC, C(max)/MIC), it was determined in the buffalo calves that when administered by intravenous or intramuscular route at 5 mg kg(-1), moxifloxacin is likely to be effective against bacterial isolates with MIC <= 0.1 mu g ml(-1).

“Lignin peroxidase from the culture filtrate of Lenzitus betulina MTCC-1183 has been purified to homogeneity using concentration by ultrafiltration and anion exchange chromatography on DEAE cellulose. The molecular weight of the purified lignin peroxidase using SDS-PAGE analysis was 43 kDa. Specific activity of the enzyme was 29.58 IU/mg. The K (m) values for veratryl

alcohol and H2O2 for the purified enzyme were 54 and 81 mu M, respectively. The k (cat) value of the purified enzyme was 2.3 s(-1) using 3,4-dimethoxybenzyl alcohol as the substrate. The optimal conditions for the

lignin peroxidase assay were detected at pH 2.4 and 22A degrees C. Thermal stability of the purified enzyme has also been studied and its activation energy for deactivation was 287 kJ/mol. The purified lignin peroxidase depolymerised humic acid in presence of H2O2. Depolymerisation of coal by the L. betulina MTCC-1183 has been demonstrated using humic acid as a model of coal.”
“Species differences in oral bioavailability, first-pass metabolism and pharmacokinetics of biopharmaceutics classification system (BCS) class I compound acetaminophen were studied. The absolute bioavailability was 42.2%, 39.0%, 44.5%, 75.5% and 91.0% in chickens, LY2835219 turkeys, dogs, pigs and horses, respectively. After hydrolysis of metabolites by beta-glucuronidase/sulfatase, apparent bioavailability increased significantly in all species (turkeys: 72.4%, dogs: 100.5%, pigs: 102.2%), except horses (91.6%). Mean metabolic ratios of [acetaminophen glucuronide]/[acetaminophen] between 0 and 1 h were significantly higher after oral dosing in turkeys, dogs and pigs, revealing the role of first-pass metabolism in incomplete bioavailability. Evidence of species differences in acetaminophen metabolism is provided by differences in plasma clearance, which was inversely proportional to bioavailability.
