In-vitro labeling of RBC with 99mTc is an intricate procedure and there is always a need foran alternate blood pool imaging agent. The aim of this study was to prepare an effective nanosized liposome (NLs) similar to human RBC for blood pool scintigraphy. This study formulatesPEG-NLs and non-PEG-NLs using film method plus high pressure homogenization technique.Biodistribution studies were perfo...

introduction: to evaluate the effect of electroactivation on fertilization and embryo development up to 8-cell stage, after intracytoplasmic injection of severely amorphous sperm. material and methods: oocytes (168) from 13 patients with severe- teratospermia undergoing icsi were divided into control (83) and electro activation (85) groups. in the latter group, oocytes were electrically activat...

The objectives of the study were to assess the magnitude of the effect of the leukotriene receptor antagonist, zafirlukast, against cold air-induced bronchoconstriction following the first dose and to assess magnitude and duration after 5 days of dosing. Nineteen patients with asthma were included. In a randomized cross-over design, either zafirlukast 20 mg or 80 mg b.d. or placebo were given o...

This study examined the hypothesis that cardiomyocyte metabolism is inherently linked to the Ubiquitin Proteasome System. Rat neonatal ventricular cardiomyocytes were pulse-treated with 5 αM lactacystin for 30 min, resulting in 95% loss of proteasome activity, and then maintained in culture for up to 24 h. Pulse-treatment resulted in 36% decrease in cardiomyocyte mitochondrial reductase activit...

  Introduction: Adequate pain control is an important consideration in the post-surgical management of patients. Local nerve blockade added to general anesthesia can provide excellent pain control during and after most nasal surgical procedures. The aim of this study was to determine the combined effect of local anesthetic drugs with corticosteroids in nasal surgery. Materials and Methods: In t...

BACKGROUND Esomeprazole provides effective and long lasting inhibition of gastric acid secretion. However, the pharmacokinetics and pharmacodynamics of intravenous esomeprazole in the Chinese population remain unclear. AIM To compare the pharmacokinetics and pharmacodynamics of intravenous esomeprazole (injection and infusion) and their clinical safety and tolerability in healthy Chinese subj...

An experiment was conducted to study the effect of post-hatch feed deprivation on yolk sac utilization and subsequent performance of young broiler chickens (280) up to 35 days of age. The experimental treatments included access to feed at 8 h intervals after hatch, up to 48 h (0, 8, 16, 24, 32, 40 or 48 h). Water was offered ad libitum to all the groups immediately after placement. Results indi...

Capsaicin depolarizes primary afferent C-fibers releasing substance P (SP) whose N-terminal metabolites appear to play a role in the development of antinociception. Because some effects of SP(1-7) are similar to those of zinc, we tested the hypothesis that zinc in the extracellular area plays a role in capsaicin-induced antinociception, as measured using the abdominal stretch (writhing) assay. ...
