No Synthesis in Mouse Macrophages
The production of nitric oxide (NO) and other reactive nitrogen intermediates by cytokineactivated rodent cells is an important component of antimicrobial and/or antineoplasic activity of these cells. This pathway involves the oxidation of arginine to citrulline, with the concomitant release of NO by an inducible form of NO synthase (iNOS). Numerous cell types express iNOS after stimulation wit...
متن کاملGlyceryl ether synthesis from long chain alcohols in elasmobranch stomach.
1. The isolated stomachs of the dogfish, Squdus acanthias, and the skate, Raja erinacea, were found to incorporate long chain alcohols and acetate, but not long chain fatty acids, into glyceryl ethers. 2. The criterion for evaluation of incorporation of radioactive substrates into glyceryl ethers was the measurement of activity of individual isopropylidene derivatives separated by means of gas-...
متن کاملProximal stomach and antrum in stomach emptying.
In a series of measurements of liquid-phase gastric emptying using a radionuclide marker on 35 subjects, five were identified in whom the proximal stomach and antrum were clearly distinguishable. Three of these subjects were normal controls and two suffered from systemic sclerosis. In the three normal subjects, analysis of the movement of the liquid showed the expected movement from fundus to a...

متن کاملSynthesis of silver nanoparticles using leaves aqueous extract of Nasturtium Officinale (NO) and its antibacterial activity
Biogenic reduction of silver ion to base metal is quite rapid, readily conducted at room temperature and pressure, and easily scaled up. Synthesis mediated by plant extracts is environmentally benign. The objective of this study was to synthesis of silver nanoparticles (Ag-NPs) using leaves aqueous extract of Nasturtium Officinale R. Br. (NO) and its antibacterial activity. X-ray diffraction (X...
