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 ...
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 ...
Fasting and 24-h urine pH in patients with urolithiasis using potassium citrate
(E-century Publishing Corp, 2022-01-01)
Purpose: To evaluate the correlation between the pH readings in 24 h urine and the random fasting specimen in patients with urolithiasis using 2 methods. Methods: A total of 114 patients with urinary lithiasis using potassium ...
Influence of pH on the phototransformation process of PhotogemA (R)
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2009)
PhotogemA (R) is a hematoporphyrin derivative that has been used as a photosensitizer in experimental and clinical Photodynamic Therapy (PDT) in Brazil. Photosensitizers are degraded under illumination. This process, usually ...
In Vitro Alkaline pH Resistance of Enterococcus faecalis
(Fundação Odontológica de Ribeirão Preto, 2013-09-01)
Enterococcus faecalis is a bacterial species often found in root canals with failed endodontic treatment. Alkaline pastes are widely used in Endodontics because of their biocompatibility and antimicrobial activity, but ...
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. ...
