Background & Aim: Electronic and communication devices have largely become a part of our daily lives. And this has caused a growing concern with regards to the possible side-effects of exposure to the radiation of these devices on human health. To investigate the same, a research was undergone to study the "Effect of regular aerobic exercise on oxidative damage markers of lipids and protei...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
abstract the present study investigated the effects of task types and involvement load hypothesis on incidental learning of 10 target words (tws) in junior high schools (jhss) in givi, ardabil. the tasks deployed in this study were two input-based tasks (reading plus dictionary use with an involvement index of 3, and reading plus gap-fill task with an involvement index of 2), and one output-ba...
background: in many studies, chemicals and natural materials were tested to reduce the harmful effects of radiation. it is known that famotidine and vitamin c reduce dna damage. objective: the aim of this study was to evaluate the radioprotective effect of vitamin c, cimetidine and famotidine on gamma-radiation-induced damage on mouse bone marrow. methods: six-to-seven week male nmri mice (28 ...
Background: Ionizing radiation induces the production of reactive oxygen species (ROS), which play an important causative role in cell death. The aim of this study was to investigate the protective effects of sulfated derivatives of neutral polysaccharides extracted from Auricularia auricular (SNAAP). Materials and Methods: Whole blood samples from healthy donors treated with SNAAP at differen...
Background: Due to abscopal effect, cell damage may occur outside of the radiation field and the quantification of this effect is one of the most challenging debates in radiation therapy. The aim of this study was to estimate the abscopal effect induced in non-irradiated tumors quantitatively by means of biological effective dose (BED). Materials and Methods: Breast tumors using 4T1 and MC4-L2 ...
In this paper, we use the observations of Sunyaev-Zel’dovich effect and Xray surface brightness to reconstruct the radial profiles of gas temperature and density under the assumption of spherically symmetric distribution of gas. The reconstruction method, firstly raised by Silk & White (1978), is directly dependent on the experimental measurements of Sunyaev-Zel’dovich effect and X-ray surface ...
abstract this research is about a longitudinal case study of english morpheme acquisition by a persian speaking child l2 learner of english (2 .9-3).the goal of this research has been discovery of the child ‘s ability in acquiring of english morphemes in a persian context while only one person (the child’ s father)has been talking to her.this child has also been exposed to english languag...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
The radiation-induced bystander effect is the phenomenon which non-irradiated cells exhibit effects along with their different levels as a result of signals received from nearby irradiated cells. Responses of non-irradiated cells may include changes in process of translation, gene expression, cell proliferation, apoptosis and cells death. These changes are confirmed by results of some In-Vivo s...
