Helicobacter pylorilipopolysaccharide in the il-2 milieu activates lymphocytes from dyspeptic children
(Oxford University Press (OUP), 2003-05-01)
Distribution of oxytetracycline resistance plasmids between aeromonads in hospital and aquaculture environments: implication of tn1721 in dissemination of the tetracycline resistance determinant tet a
(American Society for Microbiology, 2000-09-01)
Oxytetracycline-resistant (OTT) mesophilic aeromonads were recovered from untreated hospital effluent (72 isolates) and from fish farm hatchery tanks (91 isolates) at sites within the English Lake District, Cumbria, England. ...
Don't lose heart - therapeutic value of apoptosis prevention in the treatment of cardiovascular disease
(Wiley-Blackwell, 2005-07-01)
Cardiovascular disease is a leading cause of death worldwide. Loss of function or death of cardiomyocytes is a major contributing factor to these diseases. Cell death in conditions such as heart failure and myocardial ...
Calcium confusion--is the variability in calcium response by sertoli cells to specific hormones meaningful or simply redundant?
(BioScientifica, 2000-10-01)
When results of more than ten different studies on hormone-induced calcium signals in Sertoli cells are taken together, a wide variety of responses emerges. The reported changes range from increased concentrations, via no ...
1,3-dipolar character of 2-vinyl quinazoline 3-oxides; first and second generation cycloaddition products
(Royal Society of Chemistry (RSC), 2006-01-01)
The reaction between the heteroaromatic N-oxides 1a, 1b and 1c with dimethyl acetylenedicarboxylate or methyl propiolate furnishes 1,3-benzodiazepines, the products of ring transformations of primarily formed cycloadducts. ...
Reappraisal of the type species ofpolysiphonia(rhodomelaceae, rhodophyta)
(Informa UK Limited, 2000-02-01)
The genus Polysiphonia Greville, nom. cons., has had a long and confused nomenclatural history. At present, Polysiphonia has a wide circumscription, including at least 200 species, but it is heterogeneous in many vegetative ...
Biological activities of lipopolysaccharides are determined by the shape of their lipid a portion
(Wiley-Blackwell, 2000-04-01)
Lipopolysaccharide (LPS) represents a major virulence factor of Gram-negative bacteria ('endotoxin') that can cause septic shock in mammals including man. The lipid anchor of LPS to the outer membrane, lipid A, has a ...
Constitutively activated nuclear factor- b, but not induced nf- b, leads to trail resistance by up-regulation of x-linked inhibitor of apoptosis protein in human cancer cells
(American Association for Cancer Research (AACR), 2006-10-01)
The tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a potent inducer of apoptosis in most, but not all, cancer cells. The molecular factors regulating the sensitivity to TRAIL are still incompletely ...
Centre and norm
(Cambridge University Press (CUP), 2004-06-01)
We establish a correlation between the structures of a group of power automorphisms of some group and their mutual commutator subgroup and consider the consequences for the norm of a group, and for its capability.
Post-transcriptional expression regulation in the yeastsaccharomyces cerevisiaeon a genomic scale
(American Society for Biochemistry & Molecular Biology (ASBMB), 2004-08-23)
Based on large-scale data for the yeast Saccharomyces cerevisiae (protein and mRNA abundance, translational status, transcript length), we investigate the relation of transcription, translation, and protein turnover on a ...
