Partial and total C-6 oxidation of gelling carrageenans. Modulation of the antiviral activity with the anionic character
(Elsevier, 2015-09)
The optimal conditions for the full C-6 oxidation of - and -carrageenans using (2,2,6,6- tetramethylpiperidinyl)oxy (TEMPO) in the presence of sodium hypochlorite and sodium bromide were assessed. The fully oxidized products ...
Biologically enhanced dissolution of a pyrite-rich black shale concentrate
(1997-01-01)
The acid leaching of a pyrite-rich black shale concentrate (7% S) was tested in this study. The experiments were performed at 5-30% pulp densities and with inoculations of Fe- and S-oxidizing thiobacilli (Thiobacillus ...
Catalytic combustion of volatile organic compounds in binary mixtures over MnOx/Al2O3 catalyst
(Elsevier Science, 2009-05-19)
In this work the catalytic performance of an alumina supported manganese oxide catalyst in ethanol, ethyl acetate, toluene and mixtures of them was studied. The reactivity of each VOC investigated increased in the following ...
Vacuum treatment to stabilize oxidation at low temperature region in porous silicon
(2020)
Oxidation in porous silicon is studied for as-etched samples and samples subjected to high vacuum at room temperature. Attenuated Total Reflectance (ATR) measurements in infrared spectroscopy for temperatures ranging from ...
Comparison of Ni and Ni-Ce/Al2O3 catalysts in granulated and structured forms: Their possible use in the oxidative dehydrogenation of ethane reaction
(Elsevier, 2014-03)
Ni and Ni-Ce/Alumina catalysts in structured form were prepared, characterized by different techniques and tested in the oxidative dehydrogenation of ethane (ODE). In order to gain further insight into active species, ...
Oxidative stress and altered steroidogenesis in the ovary by cholinergic stimulation of coeliac ganglion in the first proestrous in rats. Implication of nitric oxide
(Academic Press Inc Elsevier Science, 2016-02-29)
An ex-vivo Coeliac Ganglion-Superior Ovarian Nerve-Ovary (CG-SON-O) system from virgin rats in the first proestrous was used to test whether cholinergic stimulation of CG affects oxidative status and steroidogenesis in the ...
Electrodegradation of landfill leachate in a flow electrochemical reactor
(Pergamon-elsevier Science LtdOxfordInglaterra, 2005)
Oxidative stress in dogs with multicentric lymphoma: Effect of chemotherapy on oxidative and antioxidant biomarkers
(2015-11-01)
Introduction: Lymphoma is one of the most common types of cancer in dogs, characterized by the proliferation of lymphoid cells. The treatment of this type of cancer is usually based on drugs with high toxicity, which can ...
Nitric oxide accumulation is required to protect against iron-mediated oxidative stress in frataxin-deficient Arabidopsis plants
(Elsevier Science, 2009-01)
Frataxin is a mitochondrial protein that is conserved throughout evolution. In yeast and mammals, frataxin is essential for cellular iron (Fe) homeostasis and survival during oxidative stress. In plants, frataxin deficiency ...
