C-reactive protein (CRP) is an acute phase reactant which humoral concentration rises drastically following tissue injury or inflammation. CRP of all species binds to phosphorylcholine residues. In the present studies CRP was found to inhibit platelet-activating factor-induced platelet aggregation, and to stabilize platelet membranes against the lytic effect of lysophosphatidylcholine. Inhibiti...

Blood platelets are considered to be a peripheral marker in schizophrenia and other psychiatric disorders. Oxidative stress in schizophrenia may be responsible for changes in platelet metabolism and function; therefore, the aim of this study was to examine and compare the generation of superoxide anions and activity of an antioxidant enzyme (glutathione peroxidase [GPx]) in blood platelets in p...

This study investigated the mechanisms of platelet-activating factor (PAF)-induced angiogenesis in a mouse model of Matrigel implantation. PAF induced a doseand time-dependent angiogenic response. Inhibitors of nuclear factor (NF) B expression or action, including antisense oligonucleotides to the p65 subunit of NF B (p65 antisense) and antioxidants such as -tocopherol and N-acetyl-L-cysteine, ...

background: platelets rapidly lose their qualities usually after 5 day of storage. different standard methods have been recommended to check the quality of platelets during storage which some of them show better correlation with other quality markers during storage. the purpose of this study was to demonstrate if platelet factor 3 (pf3) assay could be an indicator of storage lesion and provide ...
