Ca2+ adsorption to lipid membranes and the effect of cholesterol in their composition
(Elsevier Science, 2010-03)
The aim of this work is to determine the binding of ionic calcium (Ca2+) to lipid membranes in which the availability of the phosphate groups to the aqueous phase is modified by the degree of saturation of the lipids and ...
Evaluación del efecto de la adición de sales estabilizantes en las propiedades fisicoquímicas y estabilidad térmica de la leche
(Universidad Nacional de Colombia, 2013-01-01)
Physicochemical characteristics measurement was done and stability test response (75% and 78% alcohol test, and Ramsdell test) was evaluated into 7 different milk samples; where one of these samples remain unaltered and ...
Calcium hydroxide root canal sealers: Evaluation of pH, calcium ion concentration and conductivity
(1997-12-01)
The calcium hydroxide ionization of four root canal sealers (Sealapex, CRCS, Sealer 26, and Apexit) was studied by measuring conductivity and pH and by conducting atomic absorption spectrophotometry. Samples 6 mm in diameter ...
Calcium hydroxide root canal sealers: Evaluation of pH, calcium ion concentration and conductivity
(1997-12-01)
The calcium hydroxide ionization of four root canal sealers (Sealapex, CRCS, Sealer 26, and Apexit) was studied by measuring conductivity and pH and by conducting atomic absorption spectrophotometry. Samples 6 mm in diameter ...
The Effect of the Ionic Strength of Nutrient Solution on Gas Exchange, Ionic Concentration and Leaf Biomass of Annona emarginata (Schltdl.) H. Rainer Variety ‘Terra-Fria’ Seedlings
(2015-01-01)
The present study aimed to test the hypothesis that different levels of the availability of mineral nutrients from Hoagland and Arnon's nutrient solution no. 2 affect the photosynthesis, ionic concentration and biomass ...
Astroglial hydro-ionic waves guided by the extracellular matrix: An exploratory model
(Ios Press, 2017-01-01)
Calcium waves are generated from the astrocyte endoplasmatic reticulum, in response to neuronal electrochemical stimulation. The waves feed back on neurons, modulating (reinforcing or depressing) their activity and the ...
Calcium release modulated by inositol trisphosphate in ruptured fibers from frog skeletal muscle
(Springer-Verlag, 1990)
To investigate the effect of inositol 1,4,5-trisphosphate on calcium release, we used fiber bundles of frog sartorius muscle mechanically permeabilized by a scratching procedure, and we detected increments in calcium ...
