(1) The proportion of motile spermatozoa decreased with time at the same rate when samples were prepared in either HEPES or phosphate buffers.
(2) One hour after direct mechanical cardiomassage (DMCM) a moderately pronounced edema of the intercellular spaces in the basal compartment of the seminiferous epithelium, normal content of lactate and succinate dehydrogenases, and a certain decrease in the activity of glucose-6-phosphate dehydrogenases and NAD- and NADP-diaphorases were noted.
(3) Changes in cardiac adenosine triphosphate (ATP), phosphocreatine (PCr) and inorganic phosphate (Pi) were followed and intracellular pH (pHi) was estimated from the chemical shift of Pi.
(4) Plasma membranes were isolated from rat kidney and their transport properties for sodium, calcium, protons, phosphate, glucose, lactate, and phenylalanine were investigated.
(5) The 0.1 M phosphate buffer eluant was electrophoretically heterogeneous and did not elicit the production of bactericidal antibodies in rabbits.
(6) The acute effect of alcohol manifested itself by decreasing mitochondrial respiration, compensated by increased glycolytic activity of the myocardium so that myocardial energy phosphate concentration remained unchanged.
(7) A retrospective study was done in 86 patients on dialysis in order to evaluate the doses of aluminum hydroxide (OH3 Al) received to achieve a better serum phosphate control.
(8) Infusion of 1 unit of 25-HCC per hour for 6 hours induced an antiphosphaturia only when administered with 0.2 units of PTH per hour, while neither agent alone changed phosphate excretion.
(9) The present results using approximately 12% hemoglobin concentration in 0.1 M Bistris buffer at pD 7 and 27 degrees C with and without organic phosphate show that there is no significant line broadening on oxygenation (from 0 to 50% saturation) to affect the determination of the intensities or areas of these resonances.
(10) The amount of phosphate incorporated per molecule was higher for NF 200 than for NF 145 and NF 68.
(11) Resorption of calcium and depositon of inorganic phosphates in the implanted ceramics suggested that ions were being exchanged with the body fluids.
(12) sn-Glycerol 3-phosphate was found to decrease the quasi-stationary concentration of Fru 2,6-P2.
(13) At constant arterial pO2, changes in coronary flow were associated with changes in energy-rich phosphates, but not systematically with changes in coronary venous pO2.
(14) Antigenic specificity was demonstrated between tricalcium phosphate ceramic and fetal bovine serum in crisscross.
(15) Rhesus monkey BAT mitochondria (BATM) possess an uncoupling protein that is characteristic of BAT as evidenced by the binding of [3H]GDP, the inhibition by GDP of the high Cl- permeability or rapid alpha-glycerol-3-phosphate oxidation.
(16) Incubation of I diaphragms with isoproterenol did not significantly increase the concentrations of AMP, IMP or inorganic phosphate, activators of phosphorylase beta activity, nor was there a decrease in ATP and glucose 6-phosphate content, allosteric inhibitors of phosphorylase beta activity.
(17) It is unclear if the changes in high-energy phosphates during endotoxin shock cause irreversibility.
(18) We tested the hypothesis that furosemide interferes with energy generation in the cochlea, and determined its effect on CO2 formation from glucose and glyceroaldehyde-3-phosphate dehydrogenase (GAPDH) activity by examining biochemical and histochemical changes in the cochlea, the kidney, and the liver.
(19) Several aminoacyl-tRNA synthetases are herein shown to catalyze the AMP----ADP and ADP----ATP exchange reactions (in the absence of tRNAs) by utilizing a transfer of the gamma-phosphate of ATP to reactive AMP and ADP intermediates that are probably the mixed anhydrides of the nucleotide and the corresponding amino acid.
(20) No difference in urinary sodium or potassium excretion was observed between SHR and WKY, but basal calcium and phosphate excretion were reduced in SHR (P less than 0.05).
Torbernite
Definition:
(n.) A mineral occurring in emerald-green tabular crystals having a micaceous structure. It is a hydrous phosphate of uranium and copper. Called also copper uranite, and chalcolite.
