The aim of this study was to evaluate the antioxidant activity exopolysaccharides (EPS) from Lactobacillus kimchi SR8. EPS exhibited strong scavenging activities for 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radicals. Two fractions (EPS-1 EPS-3) higher than EPS-2. Low-dose CEPS could significantly increase catalase (CAT) glutathione peroxidase (GSH-Px) in serum CAT, GSH-Px superoxide dismutase...

This study aimed to evaluate whether placing dose constraints on the brachial plexus (BP) could provide dosimetric benefits in patients with nasopharyngeal carcinoma (NPC) undergoing intensity-modulated radiation therapy (IMRT). Planning CT images for 30 patients with NPC treated with definitive IMRT were retrospectively reviewed. Target volumes, the BP and other critical structures were deline...

the aim of the present study was stereological evaluation of testes of azoospermic animal model using busulfan in rat. three groups of male adult rats were used in this study. the first group was injected by single dose of busulfan (10 mg kg-1) and their testes were removed on day 35 post injection. the second group received double doses of busulfan with 21 days interval and their testes were r...

abrupt cessation of morphine leads to withdrawal signs and cognitive deficits. endocannabinoid system is activated during withdrawal; therefore, the aim of the present study was to assess the effects of am281, cannabinoid antagonist/inverse agonist, on memory deficit following spontaneous morphine withdrawal. cognition was evaluated by using the object recognition task. the novel object recogni...

Background:  This study presents patient specific and organ dose estimation in computed tomography (CT) imaging of thorax directly from patient CT image using Monte Carlo simulation.  Patient's CT image is considered as the patient specific phantom and the best representative of patient physical index in order to calculate specific organ dose. Materials and Methods: EGSnrc /BEAMnr...
