Recessed-tip microelectrodes were used to measure internal pH (pHi) in the fungus Neurospora, and to examine the response of pHi to several kinds of stress : changes of extracellular pH (pHo), inhibition of the principal proton pump in the plasma membrane, and inhibition of respiration . Under control conditions, at pHo = 5.8, pHi in Neurospora is 7 .19 t 0.04. Changes of pH. between 3.9 and 9....
To establish a method of pHi regulation and to understand the pH regulation mechanism in the cell, we investigated the pHi response of unfertilized or fertilized eggs of sea urchin, applying sea water containing both weak permeant acid, acetic acid and/or base, ammonia, to eggs. Pyranine was employed as a pH indicator to measure intracellular pH (pHi) by microfluorometry. The unfertilized/ferti...
We evaluated the dye 4',5'-dimethyl-5-(and -6-) carboxyfluorescein (Me2CF) for determining the intracellular pH(pHi) of isolated, perfused proximal tubules of the salamander. The intracellular absorbance spectrum, corrected for the intrinsic absorbance of the tubule, was obtained once per second. The dye was incorporated into tubule cells by exposing them to the membrane-permeable precursor 4',...
in this paper we introduce the concept of entropy operator for continuous systems of finite topological entropy. it is shown that it generates the kolmogorov entropy as a special case. if $phi$ is invertible then the entropy operator is bounded with the topological entropy of $phi$ as its norm.
The newly isolated peptide PHI provoked a dose-dependent stimulation of glycogenolysis and gluconeogenesis in isolated rat hepatocytes; at 1 microM-PHI, both processes were increased 1.6-fold as compared with basal values. These PHI-mediated effects were accompanied by the activation of glycogen phosphorylase and the inactivation of pyruvate kinase. PHI (1 microM) also caused a 2-fold increase ...

We wanted to determine the efficacy of dobutamine infusions and Prbc transfusions on splanchnic tissue oxygen utilization by measuring gastric pHi. Physiologic parameters and pHi measurements via the use of a gastric tonometer were obtained in 21 septic patients before and after the administration of a dobutamine infusion (5 micrograms/kg/min) or the transfusion of two units of Prbc. Subsets of...
Using mAbs and immunocytochemistry we have examined the response of macrophages (M phi) after crush injury to the sciatic or optic nerve in the mouse and rat. We have established that large numbers of M phi enter peripheral nerves containing degenerating axons; the M phi are localized to the portion containing damaged axons, and they phagocytose myelin. The period of recruitment of the M phi in...
Strawberries have a very thin layer coating that easily disappears and are perishables a lot pre-harvest as such nearly 30 to 40 percent of strawberry fruits will be wasted at interval between harvest and consumption. In this study have been investigated the effect of using psyllium mucilage (Plantago psyllium) in concentrations of 6.25, 12.5 and 25 ml/l as well as Arabic gum and Arjan as edibl...
