COPD, normoxia, and early desaturation.
This duration may appear to be short. The BLUE protocol was performed by experienced operators it is true, but this was done with the aim of not interfering with the management that was underway. Doctors integrating the BLUE protocol in patient management are free to take more time. Several points explain our data, however. Since 1992, we have labeled our whole-body approach “fast-echo” because...
متن کاملDesaturation during Onyx embolization.
Editor—The Onyx Liquid Embolic System (Onyx; Micro Therapeutics, Inc., Irvine, CA, USA) is a new non-adhesive liquid embolic agent and is currently being used at our institution in the embolization of cerebral vascular lesions. The disadvantage of Onyx is that it is dissolved in dimethyl sulphoxide (DMSO). Systemic toxicity, such as pulmonary oedema, bronchospasm, bradyarrhythmia, and even card...
متن کاملDesaturation of fattv acids
Photosynthesizing flax, soybean, and safflower plants were exposed to 14CO2 at seed-setting stage for a 1 hr period. Seed was sampled periodically thereafter and the lipids were extracted. A triglyceride-rich fraction was methanolyzed ; the resultant methyl esters were analyzed by gas-liquid chromatography and assayed for radioactivity. Of the ClS unsaturated acids, oleic was the first to acqui...
متن کاملTransnitrosation signals oxyhemoglobin desaturation.
Erythrocytes dilate peripheral blood vessels as a function of oxyhemoglobin desaturation.1 This effect increases regional blood flow to hypoxic tissues. The mechanisms underlying the peripheral vasodilatory effects of desaturating erythrocytes are incompletely understood but do not involve activation of local, endothelial NO synthase (eNOS). Indeed, eNOS-derived NO itself primarily relaxes larg...
متن کاملDesaturation and hydroxylation. Residues 148 and 324 of Arabidopsis FAD2, in addition to substrate chain length, exert a major influence in partitioning of catalytic specificity.
Exchanging the identity of amino acids at four key locations within the Arabidopsis thaliana oleate desaturase (FAD2) and the Lesquerella fendleri hydroxylase/desaturase (LFAH) was shown to influence partitioning between desaturation and hydroxylation (Broun, P., Shanklin, J., Whittle, E., and Somerville, C. (1998) Science 282, 1315-1317). We report that four analogous substitutions in the FAD2...
