Objective: Oxidative stress that damages proteins result in aging and age related diseases. The aim of this study is to determine the effect of tocotrienol rich fraction (TRF) on the expression of proteins in oxidative stress-induced caenohabditis elegans (C.elegans) which has homologous genes to humans. Methods: The worms were treated with TRF prior to, after and continuously in separate group...

Due to the anti-diabetic and antioxidant activity of green tea epigallocatechin-gallate (EGCG), this research study was conducted to evaluate, for the first time, the efficacy of chronic treatment of EGCG on alleviation of hyperalgesia in streptozotocin-diabetic (STZ-diabetic) rats. Male Wistar rats were divided into control, diabetic, EGCG-treated-control and diabetic and sodium salicylate (SS...

Background: Cutaneous leishmaniasis is a common parasitic disease in Iran being mainly caused by Leishmania (L.) major. The aim of this study was to investigate the occurrence of apoptosis in the spleen and liver of female mice infected with L. major.Methods: BALB/c mice were randomly assigned into the control and experimental groups (ten mice per group). The experimental groups were subcutaneo...

The present work aimed to evaluate capability of a new molecular structure to stabilize polyethylene against thermal oxidation. Hence, effects of 3,3-bis(4-hydroxy-2-methyl-5-propan-2-ylphenyl)-2-benzofuran-1-one (thymolphthalein) on thermo-oxidative stability of high density polyethylene (HDPE) in both solid and melt states were investigated and compared with those of SONGNOX 1010, a comme...

The present work is aimed to find a new and efficient type of antioxidants for polypropylene. Hence, effects of 3,3-bis(4-hydroxy-2-methyl-5-propan-2-ylphenyl)-2-benzofuran-1-one, generally known as thymolphthalein, on thermo-oxidative stability of polypropylene in solid and melt states were evaluated and compared with those of SONGNOX 1010, an efficient commercially used antioxidant for the po...

background: elevated level of plasma homocysteine has been related to various diseases. patients with hyperhomocysteinemia can develop hepatic steatosis and fibrosis. we hypothesized that oxidative stress induced by homocysteine might play an important role in pathogenesis of liver injury. also, the cellular response designed to combat oxidative stress is primarily controlled by the transcripti...

The dynamic interplay between toxicity pathways (oxidative stress, calcium disturbances, genetic damage) caused by nanoparticles and the repair mechanisms of inhibition cell division induction death is explored in zebrafish embryo cells.

This work proposes a new method for determination of the oxidative stability of edible oils at frying temperatures using near infrared emission spectroscopy (NIRES). The method is based on heating an oil sample at a fixed temperature, followed by the acquisition of the emission spectra with time using a home-made spectrometer with an acousto-optical tunable filter (AOTF) as monochromator. The i...
