Films of pure poly(vinyl alcohol) (PVA) and samples doped with di€erent concentrations of heptahydrated ferrous sulphate were prepared using a casting method. Mechanical and relaxation properties were measured before and after irradiation. The modulus of elasticity, yield strength, tensile strength ductility and relaxation time were produced from true stress±true strain and stress relaxation me...

BACKGROUND To search for new sources of safe and inexpensive antioxidant agents which can be used to treat various oxidative stress-related diseases, the phenolic contents of leaf of Tetracarpidium conophorum were characterized and its effect on pro-oxidant induced oxidative stress in rat's genitals for the first time was investigated. METHODS The aqueous extract of the plant was prepared, th...

It is unknown if particle size plays a role in extracting health promoting compounds in wheat bran because the extraction of antioxidant and phenolic compounds with particle size reduction has not been well documented. In this study, unmilled whole bran (coarse treatment) was compared to whole bran milled to medium and fine treatments from the same wheat bran. Antioxidant properties (capacity, ...

The JAK/STAT pathway is activated in response to cytokines and growth factors. In addition, oxidative stress can activate this pathway, but the causative pro-oxidant forms are not well identified. We exposed cultures of rat glia to H2O2, FeSO4, nitroprussiate, or paraquat. We assessed oxidative stress by measuring reactive oxygen species (ROS) and oxidated proteins, we determined phosphorylated...

The aim of this study was to trace the Fe uptake pathway in leaves of Prunus rootstock (GF 677; Prunus dulcis × Prunus persica) plants treated with foliar Fe compounds using the Perls blue method, which detects labile Fe pools. Young expanded leaves of Fe-deficient plants grown in nutrient solution were treated with Fe-compounds using a brush. Iron compounds used were the ferrous salt FeSO4, th...

BACKGROUND Algal biomass, known as a potential feedstock for biofuel production, has cell wall structures that differ from terrestrial biomass. The existing methods for processing algae are limited to conventional pretreatments for terrestrial biomass. RESULTS In this study, we investigated a novel hydroxyl radical-aided approach for pretreating different types of algal biomass. In this proce...

Electron transfer from zerovalent iron (Fe0) to targeted contaminants is affected by initial Fe0 composition, the oxides formed during corrosion, and surrounding electrolytes. We previously observed enhanced metolachlor destruction by Fe0 when iron or aluminum salts were present in the aqueous matrix and Eh/pH conditions favored formation of green rusts. To understand these enhanced destruction...
