Our analysis reveal that ARE-binding protein may affect mRNA 3′ end processing and that this contributes to mRNA destabilization.”
“Standard microbiology references describe Stenotrophomonas maltophilia as oxidase negative and variable with respect to utilization of lactose and sucrose. Analysis of a collection of 766 S. maltophilia isolates indicated that approximately 20% are oxidase positive and that this species should be
reevaluated for other phenotypes, including oxidative fermentation of lactose and sucrose.”
“To address whether saccharide moieties of blood groups A, B and O antigens modulate hemolytic activity of Naja naja atra cardiotoxins (CTXs), the present study was carried out. Unlike other CTX isotoxins, hemolytic activity of CTX3 toward blood group O cholesterol-depleted red blood cells Selleck PARP inhibitor (RBCs) was notably lower than that of blood groups A and B cholesterol-depleted RBCs. Conversion of blood MK-1775 Cell Cycle inhibitor group B RBCs into blood group O RBCs by alpha-galactosidase treatment attenuated the susceptibility for hemolytic activity of CTX3, suggesting that H-antigen affected
hemolytic potency of CTX3. Pre-incubation with H-trisaccharide reduced hemolytic activity and membrane-damaging activity of CTX3. Moreover, CTX3 showed a higher binding capability with H-trisaccharide than other CTXs did. CD spectra showed that the binding with H-trisaccharide induced changes in gross conformation of CTX3. Self-quenching studies revealed that oligomerization of CTX3 was check details affected in the presence of H-trisaccharide. Taken together, our data suggest that the binding of CTX3
with H-antigen alters its membrane-bound mode, thus reducing its hemolytic activity toward blood group O cholesterol-depleted RBCs. (C) 2010 Elsevier Ltd. All rights reserved.”
“Background: Heavy alcohol consumption in HIV patients is an increasing health concern. Applying the drinking motivational model to HIV primary care patients, drinking motives (drinking to cope with negative affect, for social facilitation, and in response to social pressure) were associated with alcohol consumption at a baseline interview. However, whether these motives predict continued heavy drinking or alcohol dependence in this population is unknown.\n\nMethods: Participants were 254 heavy-drinking urban HIV primary care patients (78.0% male; 94.5% African American or Hispanic) participating in a randomized trial of brief drinking-reduction interventions. Drinking motive scales, as well as measures of alcohol consumption and alcohol dependence, were administered at baseline. Consumption and dependence measures were re-administered at the end of treatment two months later. Regression analyses tested whether baseline drinking motive scale scores predicted continued heavy drinking and alcohol dependence status at the end of treatment, and whether motives interacted with treatment condition.
