the aim of the present study was to evaluate vitamin c (vc) as a potent natural antioxidant to mitigate the genotoxic effects of arsenic trioxide and sodium fluoride in swiss albino mice in vivo. the study was divided into eight groups consisting of control treated with normal saline (group i), group ii, iii, iv, v, vi, vii and the vc group with only vitamin c (500 mg/kgbw). arsenic trioxide (4...
the purpose of the present study is to find out whether bilinguals of khuzestan-arab origin or monolinguals of iranian origin code-switch during learning or speaking english and which group is more susceptible to code-switch. to this end, the students of 24 classes from high schools and pre- university centers were screened out, and interviewed and their voices and code-switchings were recorded...

Resveratrol Reduces Oxidative Stress and Improves Arsenic Efflux in Rats Exposed To Arsenic Trioxide
Received: Revised: Accepted: May 29, 2013 September 15, 2013 September 18, 2013 The effects of resveratrol on arsenic trioxide-induced oxidative stress and arsenic efflux in spleen were determined in Wistar rats exposed to arsenic trioxide (As2O3). Wistar rats were segregated into four groups: control (0.9% normal saline), As2O3treated (2 mg/kg for 7 days, i.p.), resveratrol+As2O3-treated, resv...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
BACKGROUND Inorganic forms of arsenic are much more highly toxic to humans than organic species. Their effects include being carcinogenic, genotoxic and neurotoxic, where in the latter case, above all, they affect nervous system development in the foetus, infants and children. The main foodstuffs contributing significantly to its total dietary intake are drinking water, rice (and its products),...
Fuzzy overlay approach on three raster maps including land slope, soil type, and distance to stream can be used to identify the most potential locations of high arsenic contamination in soils. Verification of high arsenic contamination was made by collection samples and analysis of arsenic content and interpolation surface by spatial anisotropic method. A total of 51 soil samples were collected...
Rice is being increasingly exposed to inorganic arsenic and this affects half of the world population because they are rice consumers. In study, pot experiments were carried out investigate effect two dose-dependent nanomaterials (silica graphene) treatment on varied levels (2, 7 12 mg/kg). The results showed that both affected significantly with 1 mg/mL nanomaterial. Arsenic adversely plant he...
abstract recent studies suggest that prelistening activities play an important role in the development of listening comprehension (e.g. long 1990;chiang and dunkel 1992; schmidt-rinehart 1994; jensen and hansen 1995; robinson et al., 1995; buck, 1995; foster and skehan,1996; teng 1996; robinson, 2001; chang and read 2006). in line with previous studies and to shed light on a new aspect of sche...
