A recent suggestion, that transition metal complexes of unsaturated ligands can be regarded as cruciconjugated, is explored by studies of various complexes of Fe(II), the aromaticity of the resulting i systems being analyzed in terms of PMO theory. This approach is also applied to porphyrin. The conclusions are supported by preliminary SCF and MNDO calculations.

BACKGROUND Clinical epidemiology research studies, including pharmacoepidemiology and pharmacovigilance studies, use routinely collected health data, such as diagnoses recorded in national health and administrative registries, to assess clinical effectiveness and safety of treatments. We estimated positive predictive values (PPVs) of International Classification of Diseases, 10th revision (ICD-...

OBJECTIVES To determine the antiviral activity of phosphorodiamidate morpholino oligomers (PMO) and peptide-conjugated PMO (PPMO) in AG129 mice infected with dengue 2 virus (DENV-2). METHODS Antisense PMO and PPMO were designed against the 5' terminal region (5'SL) or the 3'-cyclization sequence region (3'CS) of DENV genomic RNA and administered to AG129 mice before and/or after infection wit...

The aerobic oxidation of alcohols was efficiently completed in high conversion and selectivity using Cu3/2[PMo12O40]/SiO2 as catalyst under mild reaction condition. This reaction provides a new environmentally friendly rout to the conversion of alcoholic function to carbonyl groups.

INTRODUCTION Studies in vitro reveal that endothelin-1 (ET-1) activates the alpha isoform of protein kinase C (PKC-alpha) in cultures of endothelial cells, thereby deranging cellular integrity. Sepsis and endotoxemia are associated with increased plasma concentrations of ET-1 that induce acute lung injury (ALI). We recently reported that non-selective ET-1 receptor blockade attenuates ALI in sh...

BACKGROUND Advanced glycation end products, formed by the non-enzymatic glycation of proteins with reducing sugars, are thought to play a pathogenetic role in the vascular complications of diabetes, uremia and atherosclerosis. 132-microglobulin is a major constituent of amyloid fibrils in dialysis-related amyloidosis. AGE1-modified beta2m has been found in amyloid deposits of long-term hemodial...
