BACKGROUND Routine quantification of platelet-derived extracellular vesicles (PL-EVs) may be useful in the quality control (QC) of platelet concentrates (PCs). The aim of this multicenter study was to establish and validate a consensus protocol for the standardized PL-EV quantification using conventional flow cytometers. STUDY DESIGN AMD METHODS Eighty-six PCs were investigated in five blood ...

Given a compact orientable surface , let S(() be the set of isotopy classes of essential simple loops on. We determine a complete set of relations for a function from S(() to Z to be a geometric intersection number function. As a consequence, we obtain explicit equations in R S(() and P(R S(()) deening Thurston's space of measured laminations and Thurston's compactiication of the Teichm uller s...

Pancreatic beta-cell death is known to be the cause of deficient insulin production in diabetes mellitus. Oxidative stress is one of the major causes of beta-cell death. In this study, we investigated the effects of Psoralea corylifolia L. seed (PCS) extract on beta-cell death. Oral administration of PCS extract resulted in a significant improvement of hyperglycemia in streptozotocin-induced di...

External biliary fistula (BF) or ileal bypass (IB) was performed in dogs at the time of or 2 weeks after portacaval shunt (PCS). The pathologic changes in the dog livers 2 to 4 weeks later were compared to those caused by PCS alone. Histopathologic differences between PCS alone vs. PCS plus BF or IB could not be found. Thus, the experiments did not confirm recent observations by others in rats ...

In the cerebellar cortex, Purkinje cells (PCs) receive signals from different inputs through their extensively branched dendrites and serve as an integration centre. Defects in the dendritic development of PCs thus disrupt cerebellar circuitry and cause ataxia. Here we report that specific inactivation of both Lhx1 and Lhx5 in postnatal PCs results in ataxic mutant mice with abnormal dendritic ...

Plasma cells (PCs) as effectors of humoral immunity produce Igs to match pathogenic insult. Emerging data suggest more diverse roles exist for PCs as regulators of immune and inflammatory responses via secretion of factors other than Igs. The extent to which such responses are preprogrammed in B-lineage cells or can be induced in PCs by the microenvironment is unknown. In this study, we dissect...

OBJECTIVE Post-craniotomy seizure (PCS) is reported only rarely. However, our department noted a 433% increase in PCS for a year beginning September 2010, especially after cerebrovascular surgery. Our goal was to identify the cause of our unusual outbreak of PCS. METHODS For almost one year after September 2010, cases of PCS increased significantly in our department. We analyzed 973 patients ...

Infantile hemangioma, a common benign tumor of infancy, grows quickly in the first year of life, and then regresses slowly to fibrofatty tissue in childhood. The accumulation of fibrofatty tissue in hemangioma involution indicates adipogenesis during this period. Perivascular cells (PCs) from multiple organs display multi-lineage differentiation, including adipogenesis. So we supposed that PCs ...

Chronic kidney disease (CKD) favors the development of cardiovascular disease (CVD). Protein-bound uremic toxins retained in CKD patients are considered to be emerging risk factors for CVD. One uremic toxin, p-cresyl sulfate (PCS), has now been the subject of research interest with regard to its negative impact on cardiovascular system. However, the effect of PCS on CVD remains to be elucidated...

INTRODUCTION Previous studies have shown that serum p-cresyl sulfate (PCS) and indoxyl sulfate (IS) were significantly related to clinical outcomes in patients on hemodialysis (HD). However, evidence for the relationship in elderly HD patients remains scarce. We explore whether the two toxins can predict clinical outcomes in elderly HD patients. MATERIAL AND METHODS Fifty stable HD patients m...
