Glycogen synthase kinase 3 beta (GSK-3beta) has a central role in Alzheimer's disease (AD). Selective inhibitors which avoid tau hyperphosphorylation may represent an effective therapeutical approach to the AD pharmacotherapy and other neurodegenerative disorders. Here, we describe the synthesis, biological evaluation, and SAR of the small heterocyclic(More)
The Xenopus homologue of Drosophila Fizzy and budding yeast CDC20 has been characterized. The encoded protein (X-FZY) is a component of a high molecular weight complex distinct from the APC/cyclosome. Antibodies directed against FZY were produced and shown to prevent calmodulin-dependent protein kinase II (CaMKII) from inducing the metaphase to anaphase(More)
Hepatitis C virus (HCV) is transmitted primarily by direct percutaneous exposures to blood. Since HCV RNA has been found in saliva, it has been suggested that saliva might also be a source of infection. HCV RNA in saliva from plasma HCV RNA positive patients was tested by a highly sensitive PCR method. HCV RNA was detected in 32 out of 61 saliva specimens(More)
Here we show that segregation of homologous chromosomes and that of sister chromatids are differentially regulated in Xenopus and possibly in other higher eukaryotes. Upon hormonal stimulation, Xenopus oocytes microinjected with antibodies against the anaphase-promoting complex (APC) activator Fizzy or the APC core subunit Cdc27, or with the checkpoint(More)
Integrin alpha4beta1 mediates leukocyte recruitment, activation, mediator release, and apoptosis inhibition, and it plays a central role in inflammatory pathophysiology. High-affinity, selective inhibitors of alpha4beta1, based on the Leu-Asp-Val (LDV) sequence from the alternatively spliced connecting segment-1 (CS-1) peptide of cellular fibronectin, are(More)
Flow cytometry analysis of luteal cells revealed that an important proportion of these cells are leukocytes. The percentage of leukocytes was higher in the early (42 +/- 4) and late (35 +/- 3) luteal phases than in the mid-luteal (24 +/- 2) phase. However, the proportion of macrophages did not differ between the luteal stages. The flow cytometric properties(More)
We study numerically the effects of edge and bulk disorder on the conductance of graphene nanoribbons. We compute the conductance suppression due to Anderson localization induced by edge scattering and find that even for weak edge roughness, conductance steps are suppressed and transport gaps are induced. These gaps are approximately inversely proportional(More)
We present a measurement of the W-boson mass using 200 pb{-1} of data collected in pp[over ] collisions at sqrt[s]=1.96 TeV by the CDF II detector at run II of the Fermilab Tevatron. With a sample of 63 964 W-->enu candidates and 51 128 W-->munu candidates, we measure M_{W}=80 413+/-34{stat}+/-34{syst}=80,413+/-48 MeV/c;{2}. This is the most precise single(More)
Serums from 4 species of deer and 1 species of antelope were analyzed for various components in order to define an animal disease model for sickle cell disease in people. Animal species included black-tailed deer (Odocoileus hemionus columbianus), mule deer (Odocoileus hemionus), sika deer (Cervus nippon nippon), fallow deer (Dama dama), and pronghorn(More)
Antiserum to a human prostate-specific antigen was raised in a rabbit and utilized by immunoperoxidase staining to evaluate its potential value as a diagnostic histologic marker for tumors of prostatic origin. All primary and metastatic prostatic malignancies reacted positively, whereas nonprostatic neoplasms did not stain with this procedure. This is the(More)
