Desenvolvimento de instrumentação eletrônica portátil para medida de pH em campo por meio de sensor óptico à base de filme de Polianilina
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Biotecnologia - PPGBiotecCâmpus São Carlos, 2014-05-30)
The pH measurement has an important role in biotechnological processes as enzymatic
reactions, fermentation processes and others. This ways the general objective of this work is
therefore the development of a portable ...
Exposure to pH 3.5 water has no effect on the gills of the Amazonian tambaqui (Colossoma macropomum)
(2021-05-01)
Tambaqui (Colossoma macropomum) are a model species for tropical fish physiology, but details are lacking about their ionoregulatory response to acid waters. To provide specifics, we measured unidirectional Na+ fluxes in ...
pH-responsive poly(aspartic acid) hydrogel-coated magnetite nanoparticles for biomedical applications
(2017-08-01)
A novel multifunctional nanosystem formed by magnetite nanoparticles coated with pH-responsive poly(aspartic acid) hydrogel was developed. Magnetite nanoparticles (Fe3O4) have been intensively investigated for biomedical ...
Transcriptional profiling reveals genes in the human pathogen Trichophyton rubrum that are expressed in response to pH signaling
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2010)
Trichophyton rubrum is a dermatophyte that infects human skin and nails. Its growth on keratin as its carbon source shifts the ambient pH from acidic to alkaline, which may be an efficient strategy for its successful ...
pH fronts and tissue natural buffer interaction in gene electrotransfer protocols
(Pergamon-Elsevier Science Ltd, 2017-11)
Gene electrotransfer (GET) protocols, based on the introduction into the cells of genes encoding immunomodulatory molecules, constitute a safe and powerful strategy for inducing an immune response against cancer. But GET ...

(Universidade Federal de Minas GeraisUFMG, 2015-10-23)
Aedes (Stegomyia) aegypti is an important vector of several pathogens, such as yellow fever virus, dengue virus and more recently, chikungunya fever. Despite guts physiology and intestinal pH importance in digestion and ...
Modelagem molecular do fármaco olmesartana acoplado ao receptor de angiotensina AT1 em pH ácido ou fisiológico
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIAS BIOLÓGICAS, 2019-02-15)
Hypertension is a risk factor for stroke, which predisposes patients to motor and
cognitive impairments. Excessive AT1 receptor activity in the brain is associated with
exaggerated sympathetic and hormonal responses ...
