the purpose of this study was to evaluate the use of glass capillary micropipette (gcm) as a vessel forvitrification of bovine oocytes. cumulus-oocyte complexes (cocs) were obtained from slaughter-house andwashed 5 to 6 times in the washing medium (tcm-199 + 20% fbs) and randomly assigned to treatment andcontrol group. in the first step of vitrification, cocs were exposed to first vitrification...

human interferons (ifns) are key cytokines secreted by immune system. they have several effects such as antiviral and anti tumors activity, activating immune cells and healing of multiple sclerosis. the type ifns present in humans are α, β and υ. ifn β is a polypeptide, normally produced by fibroblasts and seems to be more species-specific than ifn . structural properties of i fns are importan...

two capillary zone electrophoresis (cze) methods were developed in this study, one using an acidic buffer (sodium citrate ph = 2.5) and the other using a basic buffer (sodium tetraborate ph = 9.8). the two methods were compared on the basis of repeatability and reproducibility of results and the cze method developed with the basic buffer was then selected for further studies. the method was ful...

one of the problems encountered in ce separations of basic compounds is the adsorption of analytes onto the negatively charged capillary wall which could lead to poor repeatability of migration time and peak area. additionally, separation of enantiomers of chiral of basic drugs is commonly carried out in low ph buffer which contributes to strong ionic interaction of the cationic drug ions with ...

background and objectives: fine needle aspiration cytology (fnac) is an established out- patient procedure used in primary diagnosis of palpable thyroid lesions. a modified technique fine needle capillary sampling (fncs) obviates the need of suction, is less painful, patient friendly and reported to overcome the problem of inadequate and bloody specimens. the aim of our study was to compare the...

introduction: lobular capillary hemangioma (lch) is a benign lesion of vascular origin. it rarely involves nasal cavity which most commonly manifests as progressive nasal obstruction and epistaxis. case report: in this report we present a case of lch of the nasal cavity which occurred approximately one month after delivery. there was no recurrence after complete endoscopic resection during one ...

asymptotically exact and nonlocal third order nonlinear evolution equations are derivedfor two counterpropagating surface capillary gravity wave packets in deep water in thepresence of wind flowing over water.from these evolution equations stability analysis ismade for a uniform standing surface capillary gravity wave trains for longitudinal perturbation. instability condition is obtained and g...

Objective(s): Previous studies showed that skeletal muscle microcirculation was reduced in chronic heart failure. The aim of this study was to investigate the effects of endurance training on capillary and arteriolar density of fast and slow twitch muscles in rats with chronic heart failure. Materials and Methods: Four weeks after surgeries (left anterior descending (LAD) artery occlusion), chr...

In this paper, a very efficient method, called single matrix block analyzer (SMBA), has been developed to determine relative permeability and capillary pressure curves from spontaneous imbibition (SI) data. SMBA mimics realistically the SI tests by appropriate boundary conditions modeling. In the proposed method, a cuboid with an identical core plug height is considered. The equal dimensions of...
