Phosphoric Acid Metabolism in Cerebral Cortex

Action of protoveratrine on the metabolism of cerebral cortex. 2. Electrically stimulated cerebral-cortex tissue.

Effects of histamine on phosphoinositide metabolism in chick cerebral cortex.

Effects of histamine (HA) and agonists of HA receptors on phosphoinositide metabolism in chick cerebral cortex have been studied using two approaches - measurement of inositol 1,4,5-trisphosphate (IP3) level by a specific and sensitive IP3 receptor radioassay, and analysis of [3H]inositol phosphates accumulation in cortical slices prelabeled with myo-[3H]inositol. HA concentration-dependently e...

APP Metabolism Regulates Tau Proteostasis in Human Cerebral Cortex Neurons

Accumulation of Aβ peptide fragments of the APP protein and neurofibrillary tangles of the microtubule-associated protein tau are the cellular hallmarks of Alzheimer's disease (AD). To investigate the relationship between APP metabolism and tau protein levels and phosphorylation, we studied human-stem-cell-derived forebrain neurons with genetic forms of AD, all of which increase the release of ...

Free and membrane-bound ribosomes of rat cerebral cortex. Metabolism of ribosomal and messenger ribonucleic acid.

Free and membrane-bound ribosomes were isolated from cerebral .cortex of young rats at various times after they received simultaneous intracerebral injections of [W]uridine and [methyZ-3H]methionine. Using acid and alkaline extraction with phenol, two types of doubly labeled RNA were prepared from these ribosomes, one rich in ribosomal RNA (pH 6) and the other rich in messenger RNA (pH 8.3). Th...

High frequency sonoluminescence in sulphuric acid and phosphoric acid

Multibubblesonoluminescence (MBSL) emission spectra at different forcing frequencies ( 20, 580, 850 KHz and 1.1 MHz) in Sulphuric acid and Phosphoric acid, under different noble gases atmosphere ( Ar, Xe and He) have been investigated. Using lower frequency we observed the presence of new emissions lines which may indicate the formation of ionized species with very high energy level inside the ...
