The properties of the cGMP-dependent channel present in membrane vesicles prepared from intact isolated bovine rod outer segments (ROS) were investigated with the optical probe neutral red. The binding of neutral red is sensitive to transport of cations across vesicular membranes by the effect of the translocated cations on the surface potential at the intravesicular membrane/water interface (S...

AIM To evaluate the therapeutic effect of netrin-4 on the early acute phase of inflammation in the alkali-burned eye. METHODS Eye drops containing netrin-4 or phosphate buffered saline (PBS) were administered to a alkali-burn-induced corneal acute inflammatory model four times daily. The clinical evaluations, including fluorescein staining and inflammatory index, were performed on day 1, 4 an...

Mixed hardwood chips were treated with lignin-degrading fungi to study the effect of fungal pretreatment on bleaching characteristics of kraft pulp. Pretreated wood chips were subjected to reduced active alkali doses in comparison to untreated chips. Comparable results were obtained for pretreated chips with reduced alkali dose as was obtained with higher dose of alkali in case of untreated chi...

In this study, the effects of raw material and alkali activator properties on compressive strength geopolymer pastes were investigated. Class F fly ash (FA) blast furnace slag (S) used as materials in paste samples. The (100U, 80U-20Y, 60U-40Y, 40U-60Y, 20U-80Y, 100Y) activated using Na2SiO3 NaOH (8, 10, 12 14 M). All samples cured under laboratory conditions until test day. values 7 28th days ...

It is well known that geopolymers are a new group of binder materials alumosilicate origin. Geopolymers made by the reaction precursor aluminosilicate with alkaline activator solutions. The current research relates to low-cost and eco-friendly procedure, suitable being implemented in two easy steps. first step production solid phase based on fly ash (Obrenovac, Serbia) eggshell as waste rich ca...

Ordinary Portland cement (OPC) is currently the preferred material for creation of barriers in wells during their construction and abandonment globally. OPC, however, a very carbon-intensive with some inherent technical weaknesses. These include low casing-to-cement bond strength which may allow formation micro-annuli, turn can become conduit greenhouse gas transport (primarily methane, powerfu...

A procedure is described for the purification of a neutral protease from fermentation broths of Vibrio proteolyticus. The key feature of the purification scheme is the selective, irreversible inactivation of a contaminating exoenzyme, aminopeptidase, by alkali treatment, rather than removal of this enzyme by conventional chromatographic methods. Fermentation broths or concentrates were brought ...

The selectivity of acetylcholine (A-Ch)-activated channels for alkali cations, organic cations, and nonelectrolytes in cultured muscle cells has been studied. To test the effect of size, charge, and hydrogen-binding capacity of permeant molecules on their permeability, we have obtained the selectivity sequences of alkali cations, compared the permeability of pairs of permeant molecules with sim...

Thua nao was a Thai alkali fermented product from soybean by Bacillus and it had a special flavour and aroma. The microorganisms involved in traditional thua nao were mixed natural flora of Bacillus, B. subtilis, B. megaterium and B. cereus, contaminated from cooked soybeans. The product had a very strong smell of ammonia. Ammonia content in dried product was lower than in the wet product. The ...
