Background—Mechanisms by which the Pl (Leu33Pro) polymorphism of 3 integrins could lead to an increased risk for coronary events are unclear. This study was designed to examine the effect of this polymorphism on blood coagulation. Methods and Results—In normal subjects (12 with Pl, 9 with Pl, and 3 with Pl), we evaluated the activation of prothrombin, factor V, and factor XIII and fibrinogen re...

The disposition kinetics of O-butyryl propranolol (butyryl-PL), a model compound containing an ester moiety, after intravenous administration was compared with that of PL in rats and beagle dogs. Rats showed only 30% conversion of butyryl-PL to PL up to 2 h after dosing, whereas dogs showed nearly complete conversion within 10 min after administration. The CL(total) of butyryl-PL in rats was 5....

BACKGROUND AND AIMS Although pollen limitation of reproduction (PL) has been widely studied, our understanding of its occurrence in tropical communities, especially for bird-pollinated plants, is underdeveloped. In addition, inclusion of both quantity and quality aspects in studies of PL are generally lacking. Within hummingbird-pollinated plants, a prediction was made for higher PL for the qua...

Platelet function has been described by many laboratory assays, and PL-11 is a new point-of-care platelet function analyzer based on platelet count drop method, which counts platelet before and after the addition of agonists in the citrated whole blood samples. The present study sought to compare PL-11 with other three major more established assays, light transmission aggregometry (LTA), Verify...

Intrathymic (i.t.) inoculation of radiation leukemia virus into C57BL/6 mice induces a population of preleukemic (PL) cells that can progress into mature thymic lymphomas upon transfer into syngeneic recipients. A minimum of 10(3) PL thymic cells are required to induce lymphomas in the recipient. Most of the individual lymphomas developed in mice which were inoculated with cells of a single PL ...

growing evidence suggests that serotonin plays an important role in learning and memory and all its receptors might be implicated in this process. the present study aimed at investigating and comparing the possible involvement of 5-ht 3 and 5-ht 4 receptor (r) agonists/antagonists upon consolidation of inhibitory avoidance memory in the pre-limbic (pl) area. bilateral intra-pl microinjections o...

A 15-day study was conducted to evaluate the effects of Artemia metanauplii enriched with two commercial supplements (Easy DHA-Selco and S. presso) which contained high levels of n–3 long chain polyunsaturated fatty acids (n–3 LC-PUFA) on growth performance, stress resistance and fatty acid profile of Litopenaeus vannamei post larvae (PL). In this regard, PL were fed with three different types ...

This work reports the coating of porous silicon (PS) with LaF3 and its influence on the photoluminescence (PL) property of PS. PS samples, prepared by electrochemical etching in a solution of HF and ethanol, were coated with e-beam evaporated-LaF3 of different thicknesses. It was observed that the thin LaF3 layer on PS led to a good enhancement of PL yield of PS. But with the increasing thickne...
