Once considered only mediators of inflammation, autacoids, (histamine, prostaglandins and beta-mimetic catecholamines) have been found to be generated during specific early and late phases of immunity. They need sufficient concentrations to affect immunocytes and can modulate immunity usually by inhibiting it. Receptors for the autacoids on the immunocytes(More)
The expression of renin and angiotensinogen genes and their proteins were studied during the progression of diabetes using adult BioBreeding spontaneously diabetic rats at 1 day and 2-12 months of diabetes. The number of renin-stained cells per juxtaglomerular apparatus was determined by immunocytochemistry. Initially, at 2 months of diabetes the number of(More)
A new series of catecholamines has been prepared in which the N-alkyl substituent of dl-epinephrine or dl-isoproterenol has been extended by a methylene chain terminated by a hydroxyl group or derived functionality (e.g., carbamate or ester). These functionalized catecholamines (congeners) and model compounds were prepared with the goal of eventual(More)
The gastric antisecretory and gastrointestinal (GI) motility activity of the natural and unnatural allenic isomers and degradation products of enprostil (methyl(+/-)-7-[(1R*,2R*,3R*)-3-hydroxy-2-[(E)-(3R*)-3-hydroxy-4-phenoxy - 1-butenyl]-5-oxocyclopentyl]-4,5-heptadienoate, RS-84135-004) were studied in the rat. The natural R-allenic isomer of enprostil(More)
Managing the emerging internal mechanical stress in chips, particularly if they are 3D stacked, is a key task to maintain performance and reliability of microelectronic products. Hence, a strong need of a physics based simulation methodology emerges. This physics-based simulation, however, requires material parameters with high accuracy. A full-chip(More)
Several [(1H-imidazol-1-yl)methyl]- and [(3-pyridinyl)methyl] pyrroles were prepared and evaluated in vitro as thromboxane synthetase inhibitors in human platelet aggregation studies. A number of structures, e.g. 10b,f,g,i (respective IC50 values: 1 microM, 50 nM, 42 nM, 44 nM) showed superior in vitro inhibition of TXA2 synthetase when compared to the(More)
The effects of enprostil (+/-)-7-[(1R*,2R*,3R*)-3-hydroxy-2-[(E)-(3R*)-3-hydroxy-4-phenoxy-1- butenyl]-5-oxocyclopentyl]-4,5-heptadienoate) were studied on cardiovascular and respiratory parameters in the dog and on hematologic parameters in the rat, monkey, and human. Anesthetized dogs were instrumented to allow measurement of heart rate, systemic blood(More)
