Advanced maternal age is associated with the natural oocyte depletion, leading to low yield, high infertility treatment cancellation rates, and eventual decreases in pregnancy rates. Various innovative interventions have been introduced improve outcome of for aging patients. Numerous published data demonstrated that early follicle development was regulated by intraovarian growth factors through...

The platelet-rich plasma (PRP) has proved promising regarding its applicability in dermatology, especially in the healing of chronic ulcers. The autologous platelet-rich plasma is obtained by centrifuging the blood, so that the components are separated by density gradient. The final product is a gel rich in growth factors that act in tissue repair by activating fibroblasts and inducing extracel...

Endotoxin, the lipopolysaccharide cell wall constituent of Gram-negative bacteria, produces symptoms of the Gram-negative sepsis syndrome. By measuring endotoxin in blood from septic patients it may be possible to select a subpopulation of patients in which mortality can be prevented by treatment with anti-endotoxin antibodies. We evaluated the performance of an endotoxin-free blood-collection ...

With advances in basic science, the use of biological adjuncts is currently being explored to supplement orthopedic surgery. Platelet-rich plasma is a clinical concept of autologous intraoperative concentration of serum platelets to provide high levels of early critical growth factors for implantation into fracture, arthrodesis, or nonunion sites. The theoretical benefit of a biological adjunct...

Platelets enzymatically convert prostaglandin H(3) (PGH(3)) into thromboxane A(3). Both PGH(2) and thromboxane A(2) aggregate human platelet-rich plasma. In contrast, PGH(3) and thromboxane A(3) do not. PGH(3) and thromboxane A(3) increase platelet cyclic AMP in platelet-rich plasma and thereby: (i) inhibit aggregation by other agonists, (ii) block the ADP-induced release reaction, and (iii) su...

mefloquine (mfq), as a racemic mixture is used for the prophylaxis and treatment of malaria. stereoselective pharmacodynamic and pharmacokinetic differences have been observed for mfq. in the present study, the human blood was spiked with racemic mfq. the concentration of mfq enantiomers in various blood fractions including packed erythrocyte layer, platelet rich plasma and platelet poor plasma...
