Análise estrutural de complexos contendo te(IV) nas formas aniônica e catiônica
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2007-02-26)
In this work the synthesis and a detailed crystallochemical study of a series of complexes salts of Te(IV), with general formula [R3Te][PhTeX4] and [R3Te]2[TeX6], in
which Te(IV) atoms appears in both cationic and anionic ...
Effect of low pH on growth and shell mechanical properties of the Peruvian scallop Argopecten purpuratus (Lamarck, 1819)
(Elsevier, 2022)
Dissolution of anthropogenic CO2 modifies seawater pH, leading to ocean acidification, which might affect calcifying organisms such as bivalve mollusks. Along the Peruvian coast, however, natural conditions of low pH ...
Transcription of the Hsp30, Hsp70, and Hsp90 heat shock protein genes is modulated by the PalA protein in response to acid pH-sensing in the fungus Aspergillus nidulans
(Springer, 2011-09-01)
Heat shock proteins are molecular chaperones linked to a myriad of physiological functions in both prokaryotes and eukaryotes. In this study, we show that the Aspergillus nidulans hsp30 (ANID_03555.1), hsp70 (ANID_05129.1), ...

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 ...
Potential of hydrogen (pH) differentially modulates cadmium stress response in abscisic acid-deficient sitiens tomato mutant
(Instituto Agronômico de Campinas, 2019)
ABSTRACT Uptake of nutrients and cadmium (Cd) are dependent upon many factors, including plant species, ions concentration and pH. Tolerance to Cd-induced oxidative stress can be modulated by phytohormones such as abscisic ...
Interaction of a pH-responsive designed nanostructured peptide with a model lipid membrane
(2016-08-01)
Studying molecular interactions of soft biomolecular materials is a key step to the development of novel functional nanostructures with potential application in nanobiotechnology and nanomedicine. In current work we aimed ...
Thermal and pH dual responsive polyurethane/2-(diisopropylamino)ethyl methacrylate hybrids: Synthesis, characterization, and swelling behavior
(Taylor & Francis Ltd, 2017-12)
This article describes the synthesis and characterization of stimuli-sensitive hybrid films using 2-(diisopropylamino)ethyl methacrylate (DPA), and a polyurethane (PU) base on isophorone diisocyanate. Hybrid films with ...
Helicobacter pylori Exhibits a Fur-Dependent Acid Tolerance Response
(2011)
Background: Helicobacter pylori colonizes the acid environment of the gastric mucosa. Like other enteric bacterial pathogens, including Salmonella enterica, which must survive a brief exposure to that environment, H. pylori ...
