Possible link of different slow calcium signals generated by membrane potential and hormones to differential gene expression in cultured muscle cells
(SOCIEDAD BIOLOGIA CHILE, 2004)
The study of fluorescent calcium signals from cultured rat myotubes has provided interesting results in the past few years. Both K+ depolarization and tetanic electrical stimulation were shown to produce slow Ca2+ signals, ...
Physiological and biochemical responses of the iron chlorosis tolerant grapevine rootstock 140 Ruggeri to iron deficiency and bicarbonate
(Springer, 2013)
Background and aims Iron (Fe) deficiency chlorosis
associated with high levels of soil bicarbonate is one
of the main nutritional disorders observed in sensitive
grapevine genotypes. The aim of the experiment was
to ...
Removal of chromium(VI) and chromium(III) from aqueous solution by grainless stalk of corn
(TAYLOR & FRANCIS INC, 2008)
Grainless stalk of corn (GLSC) was tested for removal of Cr(VI) and Cr(III) from aqueous solution at different pH, contact time, temperature, and chromium/adsorbent ratio. The results show that the optimum pH for removal ...
Actin modifies Ca2+ block of epithelial Na+ channels in planar lipid bilayers
(BIOPHYSICAL SOCIETY, 2001-05)
The mechanism by which the cytoskeletal protein actin affects the conductance of amiloride-sensitive epithelial sodium channels (ENaC) was studied in planar lipid bilayers. In the presence of monomeric actin, we found a ...
Estudio del efecto de las condiciones de almacenamiento en la formación de Pirofeofitina A en aceite de oliva virgen extra y su evaluación como indicador de frescura y calidad
(Universidad de Chile, 2019)
El aceite de oliva virgen extra (AOVE) es el zumo de la aceituna extraído por prensado en condiciones especialmente térmicas. Es muy valorado por su sabor, aroma, sus propiedades nutricionales y saludables. Estas características ...
Numerical simulation of cation exchange in fine-coarse seawater slurry pipeline flow
(Elsevier Ltd, 2018)
Slurry pipelines transporting a coarse—the comminution product—and a fine fraction, both in the presence of
seawater, can cause an alteration of the liquid phase chemical composition. In the present paper, we present ...
Study of Singlet Oxygen Equilibrium in Dioctadecyldimethylammonium Chloride Vesicles Employing 2-(n-(N,N,N-trimethylamine)-n-alkyl)- 5-alkylfuryl Halides
(2007)
Steady state photolysis and time resolved near infrared
luminescence detection were employed to study the reaction
kinetics of singlet oxygen with three different lipid-soluble
probes incorporated in large unilamellar ...
Design of chitosan nanocapsules with Compritol 888 ATO® for imiquimod transdermal administration. Evaluation of their skin absorption by Raman Microscopy
(Springer, 2020)
Purpose Design imiquimod-loaded chitosan nanocapsules for transdermal delivery and evaluate the depth of imiquimod transdermal absorption as well as the kinetics of this absorption using Raman Microscopy, an innovative ...
Comparative studies on glucose phosphorylating isoenzymes of vertebrates. Identification and characterization of amphibian liver hexokinases
(1978)
Glucose phosphorylating activities were measured in liver extracts from two urodeles and twenty-six anurans. Fractionation on diethylaminoethyl-cellulose columns of liver extracts from these amphibians permitted the ...
Differentially poised vesicles underlie fast and slow components of release at single synapses
(Rockefeller University Press, 2020)
In several types of central mammalian synapses, sustained presynaptic stimulation leads to a sequence of two components of synaptic vesicle release, reflecting the consecutive contributions of a fast-releasing pool (FRP) ...
