Ceftazidime is a broad-spectrum cephalosporin with high-level activity against a variety of Gram-negative pathogens, including Pseudomonas aeruginosa. Improved outcomes are associated with cumulative percentages of a 24-h period that the drug concentration exceeds the MIC under steady-state pharmacokinetic conditions (%TMIC) of >45 to 70% of the dosing interval. Optimal dosing to achieve a 90% ...

The toxic effect of the dinoflagellate Prorocentrum lima on juvenile American whiteleg shrimp Litopenaeus vannamei and giant lion-paw scallop Nodipecten subnodosus was evaluated. Organisms were exposed to three densities (500, 2000, or 5000 cells mL(-1)), superoxide dismutase activity and soluble protein in the hepatopancreas and muscle were determined at 1, 6, 24 and 48 h after challenge. Shri...

We report the effect of Stryphnodendron adstringens on the trypanosomatid Herpetomonas samuelpessoai. The parasites were grown at 28 degrees C in a chemically defined medium containing crude extract and fractions at concentrations from 100 to 5000 microg/ml obtained from S. adstringens. Concentrations of 500, 1000, 2500, and 5000 microg/ml both crude extract and semi-purified fraction progressi...

BACKGROUND The study assessed the antiviral activity of TMC353121, a respiratory syncytial virus (RSV) fusion inhibitor, in a preclinical non-human primate challenge model with a viral shedding pattern similar to that seen in humans, following continuous infusion (CI). METHODS African green monkeys were administered TMC353121 through CI, in 2 studies. Study 1 evaluated the prophylactic and th...

Present study was undertaken to investigate the influence of D-galactose binding lectin from Erythrina indica Lam. on the eggs and second instar larvae (64-72 hr) of melon fruit fly, Bactrocera cucurbitae (Coquillett). The lectin from E. indica seeds was extracted and purified by affinity chromatography using asilofetuin linked porous amino activated silica beads. The effects of various concent...

BACKGROUND HCP1004 is a newly developed fixed-dose combination of naproxen (500 mg) and esomeprazole strontium (20 mg) that is used in the treatment of rheumatic diseases and can reduce the risk of nonsteroidal anti-inflammatory drug-associated ulcers. The aim of this study was to evaluate the pharmacokinetics (PK) and safety of HCP1004 compared to VIMOVO(®) (a marketed fixed-dose combination o...

BACKGROUND Consumption of fruit and vegetables is associated with improved health and a decreased prevalence of chronic degenerative processes. OBJECTIVES The objectives were to assess the bioavailability of vitamin C from orange juice and its influence on plasma vitamin C and 8-epi-prostaglandin F(2 alpha) (8-epi-PGF(2 alpha)) concentrations in a healthy human population. DESIGN Six men an...

There is no report of the use of antisnake venom (ASV) in the neonatal age group in literature. We report a 27 days old female neonate who presented with neuroparalytic manifestations of snake bite and was treated successfully with ASV. A total of 50 vials (500 mL) of polyvalent antisnake venom were given as infusion in hourly aliquots of 50 mL, over 72 hours.

The present study evaluated the antimutagenic and anticancer activities of A. marina leaf extract. The antimutagenic activity of ethanol and water extracts of A. marina leaf (concentration 10 mg/plate for 48 h) was evaluated using the Salmonella typhimurium TA100 strain in the Ames test with (+S9) and without (−S9) metabolic activation, and its anticancer effect with concentrations of 200, 400,...

The impact of different patterns of feed restriction between d 1 and 15 of the estrous cycle on subsequent reproductive performance of 23 trios of littermate gilts was tested. Some gilts were fed a high plane of nutrition (HH gilts) throughout the cycle, in contrast to HR gilts, which were restricted from d 8 to 15, and RH gilts, which were restricted from d 1 to 7. During feed restriction, wei...
