Intracellular channels are located on the membranes of intracellular organelles and are involved in ion transfer, within the cytosolic compartments, in response to internal stimuli. Recently, various types of inositol 1,4,5-trisphosphate- and ryanodine-sensitive Ca(2+)-release channels, mitochondrial voltage-dependent anion channels, and a vesicular Cl-

International Journal of Antimicrobial Agents, 1997
The intracellular location of some microorganisms allow them to resist antibiotics with poor ability to penetrate eukaryotic cell membranes, such as the beta-lactam compounds. Pharmacokinetic and pharmacodynamic properties of antibiotics within eukaryotic cells have been defined in the last two decades.

Trends in Genetics, 1999
Our present understanding of intracellular protein degradation developed from an attempt to understand the metabolic stability of proteins in cells. With the unravelling of its complex biochemical machinery has come a realization that protein degradation plays an important role in the most crucial events in the cell cycle, in signal transduction and in

Critical Reviews in Microbiology, 1999
Intracellular parasites and endosymbionts are present in almost all forms of life, including bacteria. Some eukaryotic organelles are believed to be derived from ancestral endosymbionts. Parasites and symbionts show several adaptations to intracellular life.

Intracellular Compartmentalization of Potassium
American Journal of Kidney Diseases, 1989The evidence that there is intracellular compartmentalization of potassium is indirect but diverse. Intracellular electrode measurement of potassium activity, 42K radioisotope studies, and more recently 39K nuclear magnetic resonance (NMR) all support such compartmentalization.

In the quantification of buffering the distinct roles of bicarbonate and of other buffers must be taken into account. The determination of the total non-bicarbonate buffer value, betaa, in intact tissues is complicated by active pH regulation and by heterogeneity of cytoplasm with respect to betaa, while heterogeneity with respect to pH in vivo could ...

The macula is predisposed to edema in various retinal conditions, even when the insult is remote from the macula. The various factors that may predispose the macula to edema include high metabolic activity, radial arrangement of the Henle's layer, lack of inner layers at the fovea, and lack of blood supply at the fovea.

Measurement of Intracellular pH
2003The activity of most cellular processes is sensitive to pH. Cells therefore tightly control cytosol pH within narrow bounds. Measurement of cytosolic pH is of interest in studying many processes, including pH regulatory transport proteins. Key approaches that have been used to determine intracellular pH include pH-sensitive microelectrodes, nuclear ...

Apoptosis Is Dependent on Intracellular Zinc and Independent of Intracellular Calcium in Lymphocytes
Experimental Cell Research, 1994Changes in intracellular Ca2+ concentration ([Ca2+]i) are believed to have a crucial role in triggering apoptosis, the process whereby cells are eliminated during tissue turnover, hormone-mediated tissue reabsorption, clonal selection in the thymus, T cell-mediated cytotoxic reactions, and many other physiological and pathological processes.

Control of intracellular ionized calcium concentration by sarcolemmal and intracellular mechanisms
Journal of Molecular and Cellular Cardiology, 1984The regulation of the resting intracellular ionized calcium concentration [( Ca2+]i) has been studied in ferret papillary muscle using the photoprotein aequorin to measure [Ca2+]i. Elevating [Ca2+]o produced an initial rapid increase of [Ca2+]i and tension which then decayed to a steady level. This secondary fall of [Ca2+]i is attributed to a secondary
