OBJECTIVE Beta-cell proliferation is an important mechanism underlying beta-cell mass adaptation to metabolic demands. We have examined effects, in particular those mediated through intracellular cAMP signaling, of the incretin hormone analog exendin-4 on cell cycle regulation in beta-cells. RESEARCH DESIGN AND METHODS Changes in islet protein levels of cyclins and of two critical cell cycle ...
Thrombin treatment of the coagulation factor VIII results in a rapid activation of procoagulant activity with a subsequent first order decay. The structural requirements for thrombin-activated factor VIII were characterized using recombinant-derived human factor VIII and site-directed DNA-mediated mutagenesis. Thrombin-activated human recombinant-derived factor VIII was isolated in an active fo...
Physiological concentrations of NaCl inhibit the hydrolysis of von Willebrand factor (VWF) by ADAMTS-13. This effect is because of the specific binding of chloride ions to VWF. Urea-induced unfolding was measured in the presence of NaCl, CH3COONa, and NaClO4 at pH 8.0, 25 degrees C, for multimeric VWF, the recombinant A1-A2-A3 VWF domains, and the A1 domain. Chloride stabilizes the folded confo...
Among women, the A2 allele of CYP17 has been associated with elevated levels of endogenous steroid hormones; however, it does not seem to be a strong independent risk factor for breast cancer. We assessed the association between the A2 allele of CYP17 and invasive endometrial cancer risk in a case-control study nested within the Nurses' Health Study cohort (cases: n = 184; controls: n = 554). W...
Benedictine prior Father Gregoire Lemercier thought he was going mad. So he called in a psychiatrist. The psychiatrist soon sorted him out. Father Lemercier was most impressed. He considered that the benefits of Freudian analysis should be bestowed upon the other monks. called in a woman psychiatrist, Professor Frida Zmud, to 'confront monks with the problems of sexuality'. *he group therapy se...
The activity of teichomycin A2 was compared with that of vancomycin in vitro against clinical isolates of staphylococci and enterococci. Teichomycin A2 was more active than vancomycin active against all isolates tested. Synergistic studies also demonstrated that teichomycin A2 combined with rifampin is more active than vancomycin combined with rifampin against Staphylococcus aureus and Staphylo...
We prove an identity for Hall–Littlewood symmetric functions labelled by the Lie algebra A2. Through specialization this yields a simple proof of the A2 Rogers–Ramanujan identities of Andrews, Schilling and the author. Nous démontrons une identité pour les functions symétriques de Hall–Littlewood associée à l’algèbre de Lie A2. En spécialisant cette identité, nous obtenons une démonstration sim...
Immunoselection with HLA-A2 or HLA-A1 specific alloantisera has been utilized to isolate spontaneously arising and mutagen-induced variants from the B lymphoblastoid cell line T5-1 (HLA haplotypes DR3, B8, A1 and DR1, B27, Cw1, A2). Such variants are characterized by reduced reactivity with alloantisera of the selecting specificity, but normal reactivity with alloantisera directed to the other ...
Vascular endothelial cell surface expression of annexin A2 and its binding partner p11 is a key element in maintaining fibrinolytic balance on blood vessel surfaces. In the recent decade, investigators have made significant progress toward understanding the mechanisms that regulate heterotetrameric (A2*p11)(2) receptor translocation from the cytoplasm to the outer cell surface. Accumulating evi...
Respiratory syncytial virus (RSV) is the only infectious disease for which a monoclonal antibody (MAb) is used in humans. Palivizumab (PZ) is a humanized murine MAb to the F protein of RSV. PZ-resistant viruses appear after in vitro and in vivo growth of RSV in the presence of PZ. Fitness for replication could be a determinant of the likelihood of dissemination of resistant viruses. We assessed...
