Abstract:

Reduction behaviors of o, m and p nitro benzoic acids have been investigated electrochemically on glassy carbon and stainless steel (SS-316) electrodes. The aqueous methanolic solution (1:1) of o,m and p nitro benzoic acids (1mM each) was used to observe the effects of scan rates at pH 5.0,7.0 and 9.0. At various scan rates, peak potential (Ep) shifted towards the cathodic side which indicates that these reductions are irreversible and diffusion-controlled processes. The linear nature of Ipc vs.√V plots and constant values of Ipc vs.√V indicates nitrobenzoic acids reduction is a diffusion-cont

One interesting approach to fight tuberculosis is the use of prodrugs that often have shown improved biological activities over drugs with poor absorption or difficulty to cross membranes. Previous studies demonstrate that weak acids such as benzoic acid, present antimycobacterial activity. Moreover, esters of those acids revealed to be a viable alternative since they may diffuse more easily through the cell membranes. Previously we showed that mycobacteria can easily activate benzoic acid esters by conversion to the corresponding acid. Since Zhang postulated that the activity of the acids can

Volume regulation of C6 glioma cells was studied while the bath osmolality was reduced from 300 to 150 mosmol/kg. Exposure to a hyposmotic challenge elicited a typical regulatory volume decrease (RVD). No regulatory volume increase was observed upon restoration of isosmotic conditions. During a second subsequent hyposmotic challenge, the cells did not respond with RVD. High extracellular K+ concentration and the K+ channel blockers Ba2+ and quinine inhibited the RVD. RVD was abolished after Cl- was replaced by gluconate and by the Cl- channel blocker 5-nitro-2(3-phenylpropylamino)benzoic acid.

Abstract:

Luminal isobutyrate, a relatively poor metabolized short-chain fatty acid (SCFA), induces HCO3secretion via a Cl-independent, DIDS-insensitive, carrier-mediated process as well as inhibiting both Cl-dependent and cAMP-induced HCO3secretion. The mechanism(s) responsible for these processes have not been well characterized. HCO3secretion was measured in isolated colonic mucosa mounted in Lucite chambers using pH stat technique and during microperfusion of isolated colonic crypts.14C-labeled butyrate,14C-labeled isobutyrate, and36Cl uptake were also determined by apical membrane vesicles (AMV) is

Abstract:

Cells involved in the retrieval and metabolic conversion of amino acids undergo significant increases in size in response to amino acid uptake. The resultant adaptive responses to cell swelling are thought to include increases in membrane K+ and Cl− permeability through activation of volume-sensitive ion channels. This viewpoint is largely based on experimental models of hypotonic swelling, but few mammalian cells experience hypotonic challenge in vivo. Here we have examined volume regulatory responses in a physiological model of cell-swelling alanine uptake in immortalized hepatocytes. Alanin

Abstract:

During stroke or head trauma, extracellular K+concentration increases, which can cause astrocytes to swell. In vitro, such swelling causes astrocytes to release excitatory amino acids, which may contribute to excitotoxicity in vivo. Several putative swelling-activated channels have been identified through which such anionic organic cellular osmolytes can be released. In the present study, we sought to identify the swelling-activated channel(s) responsible ford-[3H]aspartate release from primary cultured astrocytes exposed to either KCl or hypotonic medium.

However, their atmospheric chemistry, physical transformation, and impact on climate, environment, and human health remain poorly understood. Here, the yields and chemical composition at the molecular level of gas- and particle-phase products originating from the photooxidation of one of these VCPs, benzyl alcohol (BnOH), are reported.

1. The effects of hypoosmotic stress on cell volume and amino acid efflux were evaluated in the human neuroblastoma cell line CHP-100 with the Coulter Counter Multisizer and radiolabeled amino acid efflux, respectively. 2. CHP-100 cells swelled by approximately 35 +/- 5% (means +/- SE) when the osmolarity of the solution was decreased from 290 to 190 mOsm/kg H2O. The rapid swelling was followed by a biphasic regulatory volume decrease (RVD). 3. In cells loaded with 14C-taurine, hypoosmotic stress induced a 300 +/- 22% (n = 23, P < 0.05) increase in taurine efflux compared with controls. Thi

The sublimation enthalpies were obtained from the vapor pressure‐temperature dependencies measured using the classic Knudsen effusion mass loss and the transpiration methods.
