Localização e orientação dos quimiorreceptores de CO2 e/ou pH envolvidos no controle dos reflexos cardio-respiratórios e da respiração aérea em jeju, Hoplerythrinus unitaeniatus (Teleostei, Erythrinidae).
(Universidade Federal de São CarlosBRUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCF, 2004-01-03)
In the present study we determined the location and orientation of the CO2 and/or pH chemoreceptors and analyzed the cardio-respiratory responses and the aerial respiration in jeju (Hoplerythrinus unitaeniatus) during ...
Effect of pH on the rheological response of reconstituted gastric mucin
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2015-05-01)
The rheological response of reconstituted gastric mucin was studied by time dependent rheological experiments as function of pH. Mucin concentrations of 5% and 10% were prepared in buffer dispersions at pH of 1.15, 2.00, ...
A silica supported tricarbocyanine based pH nanosensor with a large Stokes shift and a near infrared fluorescence response: performance in vitro and in live cells
(Royal Society of Chemistry, 2017-05)
We report the synthesis of a near-infrared (NIR) fluorescent pHprobe with a remarkable Stokes shift reported (∼ 135 nm) basedon a tricarbocyanine (Cy-PIP). The fluorescent molecule wasanchored to SiO2 nanoparticles ...
Intracellular pH sensing is altered by plasma membrane PIP aquaporin co-expression
(Springer, 2010-09)
The plant plasma membrane barrier can express aquaporins (PIP1 and PIP2) that show two intriguing aspects: (1) the potential of modulating whole membrane water permeability by co-expression of both types, which have recently ...

Use of pH Gradients in Responsive Polymer Hydrogels for the Separation and Localization of Proteins from Binary Mixtures
(American Chemical Society, 2018-10)
Using a molecular-level equilibrium theory where proteins are described using their crystallographic structure, we have studied protein adsorption from binary and ternary mixtures of myoglobin, lysozyme, and cytochrome c ...
The dermatophyte Trichophyton rubrum secretes an EDTA-sensitive alkaline phosphatase on high-phosphate medium
(2003-12-01)
In this communication, we show that the growth of isolate H6 of the dermatophyte Trichophyton rubrum on non-buffered medium and under saturating phosphate conditions is dependent on the initial growth pH, with an apparent ...
