Radiation-grafting of thermo- and pH-responsive poly (N-vinylcaprolactam-co-acrylic acid) onto silicone rubber and polypropylene films for biomedical purposes
(Elsevier B.V., 2014-04-01)
This work focuses on the effects of gamma-ray irradiation conditions on the stimuli-responsiveness of polypropylene (PP) films and silicone (SR) rubber substrates grafted with N-vinylcaprolactam (NVCL) and acrylic acid ...
Temperature effects on the metabolism of amphibians and reptiles: Caveats and recommendations
(2017-01-01)
Introduction All animals need energy. Indeed, each and every activity, or behavior, an animal will engage in throughout its lifetime will require the use of energy. As in the majority of other animals, Squamate reptiles ...
Interação microbiana e metanogênese em ruminantes: uma revisão
(Universidade Federal de Minas GeraisBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASUFMG, 2019-09-09)
Animal production contributes significantly to the greenhouse gases emission of anthropogenic origin. Enteric and ruminal fermentation produce methane that represents the more important of these gases. This review aimed ...
Insights into Hydrocarbon Assimilation by Eurotialean and Hypocrealean Fungi: Roles for CYP52 and CYP53 Clans of Cytochrome P450 Genes
(Humana Press, 2017-09)
Several filamentous fungi are able to concomitantly assimilate both aliphatic and polycyclic aromatic hydrocarbons that are the biogenic by-products of some industrial processes. Cytochrome P450 monooxygenases catalyze the ...
Substrate and product-assisted catalysis: Molecular aspects behind structural switches along organic hydroperoxide resistance protein catalytic cycle
(American Chemical Society, 2020-05)
Bacteria contain a large repertoire of enzymes to decompose oxidants, such as hydroperoxides. Among them, organic hydroperoxide resistance (Ohr) proteins play central roles in the bacterial response to fatty acid peroxides ...
The anti-cancer agent guttiferone-A permeabilizes mitochondrial membrane: Ensuing energetic and oxidative stress implications
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011)
Guttiferone-A (GA) is a natural occurring polyisoprenylated benzophenone with cytotoxic action in vitro and anti-tumor action in rodent models. We addressed a potential involvement of mitochondria in GA toxicity (1-25 mu ...
Controle do fornecimento e da utilização de substratos energéticos no encéfalo
(Academia Brasileira de Neurologia (ABNEURO), 1995-09-01)
Correspondendo a apenas 2% do peso corpóreo, o cérebro apresenta taxa metabólica superior à maioria dos demais órgãos e sistemas. A maior parte do consumo energético encefálico ocorre no transporte iônico para manutenção ...
The Chapman-type rearrangement in pseudosaccharins: The case of 3-(methoxy)-1,2-benzisothiazole 1,1-dioxide
(Elsevier Science, 2008-12)
The thermal Chapman-type rearrangement of the pseudosaccharin 3-(methoxy)-1,2-benzisothiazole 1,1-dioxide (MBID) into 2-methyl-1,2-benzisothiazol-3(2H)-one 1,1-dioxide (MBIOD) was investigated on the basis of computational ...
Why are MoS2 monolayers not a good catalyst for the oxygen evolution reaction?
(Elsevier Science, 2020-10-30)
We use density functional theory based calculations to study the energetics of the oxygen evolution reaction on a monolayer of MoS2. This material, a prototypical example of a layered transition metal dichalcogenide, is ...
