Phosphorous Metabolism of Brain
This small book amply fulfills the promise of its title; it is one of the best books on a specific aspect of brain metabolism to appear in recent years. The first two chapters cover phosphorus metabolism in the brain in vivo and include studies on the levels of phosphorylated compounds in the brain under various conditions. In addition, changes in the phosphate levels in the developing brain ar...
متن کاملNucleic acids through condensation of nucleosides and phosphorous acid in the presence of sulfur
Short phosphorothioate oligonucleotides have been prepared by refluxing an equimolar mixture of thymidine and triethylammonium phosphite in toluene in the presence of elemental sulfur. Desulfurization and subsequent digestion of the products by P1 nuclease revealed that nearly 80% of the internucleosidic linkages thus formed were of the canonical 3´,5´-type.
متن کاملPhosphorous Efficiency and Tolerance Traits for Selection of Sorghum for Performance in Phosphorous-Limited Environments
Sorghum (Sorghum bicolor (L.) Moench) is widely cultivated in West Africa (WA) on soils with low phosphorus (P) availability. Large genetic variation for grain yield (GY) under low-P conditions was observed among WA sorghum genotypes, but information is lacking on the usefulness of P-tolerance ratios (relative performance in –P [no P fertilizer] vs. +P [with P fertilizer] conditions) and measur...
متن کاملOrganic phosphorous distribution in chicken bone matrix
Non-collagenous, soluble proteins and collagen have been extracted quantitatively from freshly dissected chicken bone at 4 ûC in presence of protease inhibitors, and their content in organic phosphorus assayed. We found that non-collagenous proteins were not covalently bound to collagen in chicken bone, as in some calcified tissues. They represented 30 p. 100 of the organic matrix and bound 75 ...
متن کاملAcid-base disturbances in acute asthma.
The clinical features, arterial blood gases, and acid-base profile were examined in 229 consecutive episodes of acute asthma in 170 patients who required hospitalization. A simple respiratory alkalosis was the most common acid-base disturbance, occurring in 48 percent of the episodes. Metabolic acidosis, either alone or as part of a mixed disturbance, was noted in 28 percent. Of 60 episodes pre...
