Atherosclerotic lesions preferentially develop in areas of the vasculature exposed to nonlaminar blood flow and low fluid shear stress, whereas laminar flow and high fluid shear stress are athero-protective. We have identified a set of genes including NAD(P)H:quinone oxidoreductase-1 (NQO1), heme oxygenase-1 (HO-1), ferritin (heavy and light chains),(More)
Plasmodium falciparum DNA, isolated from the merozoite stage, was cleaved with HindIII and cloned in pBR322 and lambda L47.1 vectors. Plasmid clones containing 13.4, 7.0, 4.3, 4.1 and 1.5 kb inserts were characterized in some detail. The inserts contain several repeating units of smaller size. Nucleic acid hybridization studies showed that the repeat(More)
Two different vectors, LTR-NEO-LTR and LTR-CAT-LTR, were constructed and deletions were introduced in the upstream LTR at -299 and at -140. These deletion mutants were introduced into QT6 cells under transient expression conditions, and the levels of transcription were monitored by dot blot hybridization or by CAT assays. The results indicate that the(More)
The mucosal lining of the human intestine is constantly bathed in a milieu of commensal gut flora, the vast majority of these being nonpathogenic microorganisms. Here, we demonstrate that microbial-epithelial cell interactions not only affect proinflammatory pathways but also influence beta-catenin signaling, a key component in regulating epithelial cell(More)
Salmonella-epithelial cell interactions are known to activate the proinflammatory NF-kappaB signaling pathway and have recently been found to also influence the beta-catenin signaling pathway, an important regulator of epithelial cell proliferation and differentiation. Here, using polarized epithelial cell models, we demonstrate that these same(More)
Four of six human monoclonal IgM proteins were found to react best with Klebsiella polysaccharides containing 3,4py beta DGal (pyruvic acetalated D-galactopyranose), one with Klebsiella polysaccharides with 4,6pyDGlc; the sixth is uncharacterized. The combining sites of two of these (IgMWEA and IgMNAE) were essentially indistinguishable by quantitative(More)
Synthesis and antibacterial activity of some novel urea and thiourea derivatives (7a-7k, 8a-8f) of anacardic acid prepared from commercially available anacardic acid which is obtained from natural product Cashew Nut Shell Liquid (CNSL). Compounds (7a-7k, 8a-8f) were tested for Gram positive and Gram negative bacterial cultures. Most of the compounds were(More)
The tetrasaccharide-alditol, RL 0.8, from one stage of Smith degradation of Klebsiella K33, was subjected to Smith degradation to yield a disaccharide-alditol. The purified disaccharide-alditol was characterized by sugar analysis, methylation analysis, and mass spectrometry. The following structure was found. (formula see text)
In order to study the biochemistry and genetics of the virulent virus MB78 of Salmonella typhimurium, 31 temperature-sensitive mutants of the phage were isolated following mutagenesis with N-methyl-N'-nitro-N-nitrosoguanidine. These have been classified into six complementation groups (A through F). Linkage between different complementation groups has been(More)
An aldotriouronic acid was isolated from the acid hydrolyzate of the polysaccharide from Klebsiella Type 61 (K-61), and its structure was established. Degradation of the permethylated polysaccharide with base established the identity of the sugar unit preceding the glucosyluronic acid residue. The modes of linkage and the sequence of different sugar(More)
