Zinc oxide nanoparticles (ZnO NPs) have many biomedical applications such as chemotherapy agents, vaccine adjuvants, and biosensors but its hemocompatibility is still poorly understood, especially in the event of direct contact of NPs with blood components. Here, we investigated the impact of size and surface functional groups on the platelet homeostasis. ZnO NPs were synthesized in two differe...

Removal of calcium by either citrate, oxalate, or ethylenediaminetetraacetate inhibited coagulation of blood at an early stage and prevented the release of beta-lysin from platelets. In contrast, heparin caused platelet agglutination and stimulated beta-lysin release in vitro and in vivo. This release was calcium dependent and may have been due to a calcium-dependent reaction in the blood coagu...
Many snake venoms comprise different factors, which can either promote or inhibit the blood coagulation pathway. Coagulation disorders and hemorrhage belong to the most prominent features of bites of the many vipers. A number of these factors interact with components of the human blood coagulation. This study is focused on the effect of Echis carinatus snake venom on blood coagulation pathway. ...
INTRODUCTION This section covers the means, as far as we now know them, by which components of the blood plasma produce an insoluble protein meshwork, or gel, at a site of blood-vessel damage. The plasma is normally completely fluid, containing all its proteins in soluble form. When the clotting system is activated at a site of blood-vessel damage, a series of proteolytic reactions is set going...
C OMPLEX ALTERATION of blood coagulation occurs in the course of a number of systemic disorders. In contrast to the congenital defects of hemnostasis which are usually characterized by a single clotting factor deficiency, the changes which may accompany acquired disease are characteristicallv multiple. These multiple defects tend to form typical patterns which reflect the physiologic abnormalit...
