introduction: origanum vulgare a rich source of natural phenolic antioxidants and has potential to be a source nutritional ingredients for functional food. herbs such as origanum have long been used in food preservation d in traditional medicine in the treatment of common ailments and have potential for positive modulation oxidation-linked diseases such as diabetes. here we investigated the eff...

An assessment of within field spatial variations in grain yield and methane (CH4) emission was conducted in lowland rice fields of Myanmar. Two successive rice fields (1(st) field and 2(nd) field) were divided into fertilized and non-fertilized parts and CH4 measurements were conducted at the inlet, middle and outlet positions of each field. The results showed that CH4 emissions at non-fertiliz...

The redox active proteins contain redox centers. These can be organic or metal compounds and complexes, which are important for their function. The redox potentials of the cofactors represent key parameters of these proteins. In chapter 3, I described the way how we generated the structure of the artificial Cb from scratch. Then, we used that structure to evaluate the redox potentials of its tw...

The electrochemical oxidation of nevirapine, an anti-HIV drug, at a glassy carbon electrode has been studied by voltammetric techniques. Nevirapine showed one well defined irreversible oxidation peak with a potential of 0.749 V in phosphate buffer at pH 10. The effects of different electrolytes, pH and scan rate on the electrochemical behaviour of nevirapine were examined to determine the optim...

The occurrence of elemental mercury in flue gases from coal combustion is a problem of current environmental concern. Oxidized mercury species can be effectively removed from the flue gases by chemical scrubbers. However, the detailed mechanism by which oxidation occurs remains unclear. Theoretical rate constants are calculated for mercury oxidation by atomic chlorine. The potential energy surf...

Abstarct: Nanostructured colloidal semiconductors with heterogeneous photocatalytic behavior have drawn considerable attention over the past few years. This is due to their large surface area, high redox potential of the photogenerated charge carriers, and selective reduction/oxidation of different classes of organic compounds. In the present paper, we have carried out a systematic synthesis of...

In the present study, Mn - Cr spinel powder was synthesized through a solid state reaction. In the next step, the electrophoretic deposition (EPD) method was used to apply the MnCr2O4 spinel, as an oxidation-resistant layer, on SUS 430 stainless steel in a potential of 300 V/cm. The coated and uncoated samples were then pre-sintered in air at 900 °C for 3 h followed by cyclic oxidation at 800 °...

Titania nano particles were synthesized at carbon paste electrode by cyclic voltammetry and then it was employed for the determination of acetaminophen in phosphate buffer at pH 7.4. Carbon paste electrode with titania nano particle displayed excellent electrochemically catalytic activities by shifting the oxidation potential of acetaminophen towards the negative side. The mass transfer process...

The loss of strength in combination with constant fatigue is a burden on cancer patients undergoing chemotherapy. Doxorubicin, a standard chemotherapy drug used in the clinic, causes skeletal muscle dysfunction and increases mitochondrial H2O2 We hypothesized that the combined effect of cancer and chemotherapy in an immunocompetent breast cancer mouse model (E0771) would compromise skeletal mus...
