perishability of blood products as well as uncertainty in demand amounts complicate the management of blood supply for blood centers. this paper addresses a mixed-integer linear programming model for blood platelets production planning while integrating the processes of blood collection as well as production/testing, inventory control and distribution. whole blood-derived production methods for...
Transfusion of blood products from an infected person with AIDS, is meant to infect recipient. Blood Products such as whole blood, red blood cells, platelets, plasma, frozen blood precipitate, factor VIII, factor IX, can be infected with HIV. Transmissions from blood factors can be seen in plasma from thousands of donors that were collected in a container and were used to treat hemophilia. Bloo...
Blood transfusion centers are under considerable pressure to produce platelet concentrates with high quality and safety due to the short shelf life of 3-5 days as well as possible bacterial and viral contaminations. For a variety of reasons, many Europeans have changed their methods of component production from whole blood using the North American standard platelet-rich plasma method to the buf...

Introduction: Endothelin 1, which is secreted by vascular endothelial cells, has been identified as the most potent vasoconstrictor. The purpose of this study was to investigate the effect of a course of endothelin-1 plasma resistance training and its relationship with blood pressure in older men. Methods: In this quasi-experimental study, 30 elderly men (mean age 62.28 ± 8.08 years, height 17...
background: lead toxicity has been reported to affect hematopoietic, nervous, reproductive, cardiovascular and urinary tract systems. many investigators have so far studied the effects of high blood lead levels on pregnancy outcomes. objective: to investigate the effects of elevated maternal blood lead during pregnancy on some trace elements and pregnancy outcomes. methods: blood lead and plasm...
the aim of this study was to evaluate the concentrations of reproductive hormones in blood plasma and in follicular fluids of different sized follicles during various stages of the estrous cycle in holstein cattle. jugular blood samples from 42 adult holstein cattle were collected immediately after the slaughter. antral fluids from small (4-5 mm), medium (6-9 mm) and large (10-20 mm) follicles ...
