Platelet glycoproteins (GP) IIb and IIIa exist as noncovalently associated Ca++-dependent heterodimer complexes within the platelet membrane and express the major platelet alloantigens Leka (Baka) and PIA1 (Zwa), which are genetic markers of GP IIb and GP IIIa, respectively. Since heterodimers immunologically related to platelet GP IIb/IIIa have been identified in a number of nucleated cell typ...

Platelet membrane glycoproteins (GP) IIb and IIIa form a Ca2+-dependent, heterodimer complex (GP IIb-IIIa) in detergent solution. To determine whether these glycoproteins were complexed or dissociated in intact human platelets, 125I-labeled whole platelets were lysed with an EDTA/Triton X-100 buffer, which stabilized both the complexed and dissociated forms of GP IIb and GP IIIa. The percentage...

We explicitly carry out the symplectic quantization of a family multifield generalized Proca (GP) electrodynamics theories. In process, we provide an independent derivation so-called secondary constraint enforcing relations---consistency conditions that significantly restrict allowed interactions in settings already at classical level. Additionally, unveil existence quantum consistency conditio...

OBJECTIVES Failure to recruit sufficient applicants to general practice (GP) training has been a problem both nationally and internationally for many years and undermining of GP is one possible contributing factor. The aim of our study was to ascertain what comments, both negative and positive, are being made in UK clinical settings to GP trainees about GP and to further explore these comments ...

The role of glucosylceramide synthase (GCS) in regulating ceramide-induced apoptosis has been widely studied. The purpose of this investigation was to evaluate the role of P-glycoprotein (P-gp) in regulating ceramide cytotoxicity by using C6-ceramide. To accomplish this, we employed HeLa cells with conditional expression of the multidrug resistance gene 1/P-gp. HeLa cells expressing P-gp (P-gp/...
