OBJECTIVES: Despite improved success with solid-organ transplant procedures, recipients remain at risk for infections, including pneumonia, due to their immunosuppressive regimens. In solid-organ transplant patients, clinical findings of pneumonia can be nonspecific, and diagnosis of pneumonia may be difficult as several conditions (drug lung, hypervolemia, infections, hemorrhage) can led to pulmonary infiltrates, mimicking pneumonia in these patients. The role of mean platelet volume, a predictor of inflammatory disease, with elevated values inversely correlated with inflammatory problems, in the diagnosis of pneumonia has not yet been investigated in solid-organ transplant patients...

Preeclampsia (PE) is a pregnancy-specific, multi-system disorder and the leading cause of maternal and perinatal morbidity and mortality in obstetrics worldwide. Excessive vasoconstriction and dysregulated coagulation function are closely associated with PE. Heat shock protein 20 (HSP20) is ubiquitously expressed under normal physiological conditions and has important roles in vascular dilatation and suppression of platelet aggregation. However, the role of HSP20 in the pathogenesis of PE remains unclear. In this study, we collected chorionic plate resistance arteries (CPAs) and serum from 118 healthy pregnant women and 80 women with PE and detected the levels of HSP20 and its phosphorylated form...

Platelets play a pivotal role in the thromboembolic, inflammatory, and immunomodulatory process. The alteration of platelet quality often affects the treatment and prognosis of critically ill patients, and has a significant correlation with mortality. With the further research on the function of the platelet, it is found that the abnormal platelet quality can present during the early stage of the illness of the critically ill patients. In order to evaluate the alterations of the platelet quality more accurately, the further studies of platelet parameters, including platelet counts (PLT), platelet hematocrit (PCT), platelet large cell ratio (PLCR), mean platelet volume (MPV), platelet distribution width (PDW), immature platelet fraction (IPF) and so on, are still be the focus of current researches in the field of critical illness...

Background and purpose: Platelets have a crucial role on vascular disease which are involved in pathogenesis of ischemic stroke. Platelet size is measured as mean platelet volume (MPV) and is a marker of platelet activity. Platelets contain more dense granules as the size increases and produce more serotonin and tromboglobulin (b-TG) than small platelets. In this study, the alteration of MPV values were investigated in patients with acute stroke, who had MPV values before stroke, during acute ischemic stroke and 7 days after the stroke...
