Reactivity of UH3 with mild oxidants

Dalton Transactions, 2008
Addition of 2 equiv of I2 to a stirring suspension of UH3 in Et2O results in vigorous gas evolution and the formation of UI4(OEt2)2 (1), which can be isolated in good yields as an air- and moisture-sensitive brick-red powder. Addition of 3 equiv of AgBr to UH3 in DME produces UBr3(DME)2 (2), while addition of 4 equiv of AgX to UH3 in DME-CH2Cl2 ...

Oxidative Histochemistry of Reactive Astrocytes

Archives of Neurology, 1962
In the present report the results of a morphologic histochemical study of oxidative enzymes in reactive astrocytes will be presented. This investigation was undertaken as an effort to determine whether reactive astrocytes show a different pattern of enzymatic activities from normal cells and if so, the duration of such changes.

Reactive oxidant species in asthma

Current Opinion in Pulmonary Medicine, 2006
This overview summarizes some recent studies on the balance of oxidants to antioxidants in patients with asthma. The aim of the review is to compare studies on the changes in oxidants/antioxidants in stable asthma or in acute exacerbation of asthma.Our review of the recent literature in this field seems to indicate conflicting findings.

Reactive carbonyl formation by oxidative and non-oxidative pathways

Frontiers in Bioscience, 2001
The spectrophotometric protein carbonyl assay is used as an indicator of protein damage by free radical reactions in vitro and in a variety of pathologies. We investigated model proteins and a variety of oxidative and non-oxidative reactions, as well as what effects hemoglobin, myoglobin, and cytochrome c might have on levels of protein carbonyls.

Characterization and reactivity of biogenic manganese oxides for ciprofloxacin oxidation

Journal of Environmental Sciences, 2014
Biogenic manganese oxides (BioMnOx) were synthesized by the oxidation of Mn(II) with Mn-oxidizing bacteria Pseudomonas sp. G7 under different initial pH values and Mn(II) dosages, and were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, and UV-Vis absorption spectroscopy.

Clarification of the Reactivity of 1,3,3,3-Tetrafluoropropene Oxides

Organic Letters, 2020
Our computation has successfully clarified the reluctant behavior of trans- and cis-1,3,3,3-tetrafluoropropene oxides 1c toward nucleophiles and led to the expectation that these epoxides would react under the Brønsted acid activation conditions. Actually, this was the case, and these epoxides smoothly opened with CF3SO3H, whose elimination after the ...

Oxidative Stress and Reactive Oxygen Species

2005
This article discusses different aspects concerning classification/nomenclature, biochemical properties and pathophysiological roles of reactive oxygen species (ROS) which are pivotal to interpret the concept of oxidative stress. In vitro studies in both the prokaryotes and eukaryotes clearly demonstrate that exogenous or constitutive and inducible ...

Aging and oxidation of reactive protein sulfhydryls

Experimental Gerontology, 2001
Protein sulfhydryls are potential sites of reversible oxidative modification by S-glutathiolation, and S-nitrosylation, but they are also susceptible to irreversible damage by oxidative conditions. In the absence of adequate antioxidant protection, these reactive sites may become useless because of this irreversible damage.

Oxidation Resistance of Reactive Atoms in Graphene

Nano Letters, 2012
We have found that reactive elements that are normally oxidized at room temperature are present as individual atoms or clusters on and in graphene. Oxygen is present in these samples but it is only detected in the thicker amorphous carbon layers present in the graphene specimens we have examined.

Reactivity of stoichiometric titanium oxide cations

Physical Chemistry Chemical Physics, 2011
We present the results of a reactivity study of titanium cationic clusters towards CO, C(2)H(2), C(2)H(4) and C(3)H(6) based on guided-ion-beam mass spectrometry and DFT calculations. We identified Ti(2)O(4)(+) and to a lesser extent TiO(2)(+) species which preferentially undergo oxidation reactions.
