We tested the hypothesis that single nucleotide polymorphisms (SNPs) within genes of the NF-κB pathway are associated with altered clinical outcome of septic shock patients. We genotyped 59 SNPs in the NF-κB pathway in a discovery cohort of septic…

Numerical modeling of the orbital evolution of interplanetary dust particles revealed that, over the past 1.2 million years, the rate of accretion of dust by Earth has varied by a factor of 2 to 3. These variations display a 100,000-year periodicity…

Background: All previously reported eukaryotic nuclear genome sequences have been incomplete, especially in highly repeated units and chromosomal ends. Because repetitive DNA is important for many aspects of biology, complete chromosomal structures…

Bacillus thuringiensis (Bt) insecticidal toxins bind to receptors on midgut epithelial cells of susceptible insects, and binding triggers biochemical events that lead to insect mortality. Recently, a 100-kDa aminopeptidase N (APN) was isolated from…

Fluorescence resonance energy transfer (FRET) from the amino acid tryptophan (Trp) as donor and a 2,3-diazabicyclo2.2.2oct-2-ene-labeled asparagine (Dbo) as acceptor in peptides of the general structure Trp-(Pro)n-Dbo-NH2 (n = 1-6) was investigated…

A rapid microcentrifuge-based method is described for preparation of Pseudomonas aeruginosa electrocompetent cells with up to 10,000-fold increased transformation efficiencies over existing procedures. This increased efficiency now enables the use…

BACKGROUND: Celiac disease (CD) is a Th1-driven autoimmune permanent enteropathy that is triggered by dietary gluten. Molecules able to shift the immune response from a Th1- to a Th2-type response have been suggested as therapeutic agents for Th1…

Angiotensin II induces vasoconstriction and vascular smooth muscle growth via stimulation of the angiotensin II type I receptor (AGTR1). Some studies have reported an association between a genetic variant (A1166C) in the 3' un-translated region of…

The Natufians of the southern Levant (15,00011,500 cal BP) underwent pronounced socioeconomic changes associated with the onset of sedentism and the shift from a foraging to farming lifestyle. Excavations at the 12,000-year-old Natufian cave site,…

The cell wall imparts structural strength and shape to bacteria. It is made up of polymeric glycan chains with peptide branches that are cross-linked to form the cell wall. The cross-linking reaction, catalyzed by transpeptidases, is the last step…

A recognized feature of psoriasis and other proliferative dermatoses is accumulation in the skin of the unusual arachidonic acid metabolite, 12R-hydroxyeicosatetraenoic acid (12R-HETE). This hydroxy fatty acid is opposite in chirality to the product…

The natural history and prognostic factors of cartilage loss in osteoarthritis of the knee were studied in subjects from a general population survey on rheumatic diseases in 1975-8. Baseline data were collected by questionnaire, physical…

We have recently reported that platelet factor 4 (PF4), a megakaryocyte-platelet protein, is a potent inhibitor of human and murine megakaryocytopoiesis. In addition, PF4 accelerated the recovery of the marrow precursor cells in 5-fluorouracil…

The Fc receptor on B lymphocytes, Fc gamma RIIB (beta 1 isoform), helps to modulate B-cell activation triggered by the surface immunoglobulin complex. Crosslinking of membrane immunoglobulin by antigen or anti-Ig F(ab')2 antibody induces a transient…

The crystal structure of an HIV-1 trans-activation response region (TAR) RNA fragment containing the binding site for the trans-activation protein Tat has been determined to 1.3-A resolution. In this crystal structure, the characteristic UCU bulge…

Calmodulin (CaM) is a 16.8-kDa calcium-binding protein involved in calcium-signal transduction. It is the canonical member of the EF-hand family of proteins, which are characterized by a helix-loop-helix calcium-binding motif. CaM is composed of N-…

Although studies in C. elegans have identified numerous genes involved in fat storage, the next step is to determine how these factors actually affect in vivo lipid metabolism. We have developed a (13)C isotope assay to quantify the contribution of…

Rat hearts were perfused with mixtures of 3-(13)Cpyruvate and 3-(13)Clactate (to alter cytosolic redox) at low (0.5 mM) or high (2.5 mM) Ca(2+) concentrations to alter contractility. Hearts were frozen at various times after exposure to these…

Anaplerotic pyruvate carboxylation was examined in hearts perfused with physiological concentrations of glucose, U-13C3lactate, and U-13C3pyruvate. Also, a fatty acid, 1-13Coctanoate, or ketone bodies were added at concentrations providing…
