Cantharoidea de México. I. Nuevas especies de Photinus (Coleoptera: Lampyridae: Photinini)
(Anales del Instituto de Biología serie Zoología, 2009)
Measuring b-Galactosidase activity at pH 6 with a differential pH sensor
(Pontificia Universidad Católica de Valparaíso, 2009)
pH at the micellar interface: Synthesis of pH probes derived from salicylic acid, acid-base dissociation in sodium dodecyl sulfate micelles, and Poisson-Boltzmann simulation
(Elsevier B.V., 2006-05-01)
The study of the H+ concentration at the micellar interface is a convenient system for modeling the distribution of H+ at interfaces. We have synthesized salicylic acid derivatives to analyze the proton dissociation of ...
New methodology for pH measurements in fuel ethanol using glass electrode
(2011-01-01)
Studies carried out with glass electrode in anhydrous ethanol and ethanol-water solutions for measuring pH values have shown that this parameter depends on the solution composition, the contact time with the solution, the ...
Molecular components of the Neurospora crassa pH signaling pathway and their regulation by pH and the PAC-3 transcription factor
(2016-08-01)
Environmental pH induces a stress response triggering a signaling pathway whose components have been identified and characterized in several fungi. Neurospora crassa shares all six components of the Aspergillus nidulans ...
Effect of calcium chloride on the pH values of several formulations of calcium hydroxide mixed with chlorhexidine digluconate
(2013)
This study evaluated the effect of the addition of 5% calcium chlorite (CaCl2) on pH values in calcium hydroxide pastes (CH), with or without 2% chlorhexidine digluconate (CHX) used as vehicle, in several periods analysis. ...
Influencia del pH en el crecimiento de quince ceoas de hongos ectomicorrizogenos
(Anales del Instituto de Biología serie Botánica, 2009)
Modulatory effects of acidic ph and membrane potential on the adsorption of ph-sensitive peptides to anionic lipid membrane
(2021-05-01)
Anionic lipid membrane electrostatic potential and solution pH can influence cationic peptide adsorption to these bilayers, especially those containing simultaneously acid and basic residues. Here, we investigate the effects ...
Saliva and tongue coating pH before and after use of mouthwashes and relationship with parameters of halitosis
(Faculdade De Odontologia De Bauru - USP, 2011)
OBJECTIVES: The aim of this work was to evaluate saliva and tongue coating pH in oral healthy patients with morning bad breath before and after use of different oral mouthrinses. MATERIAL AND METHODS: Saliva and tongue ...
