today, the intractions of the immune system of the immune system, nutrition, and nervous system are one of the main research areas of interest in immunology and disease treatment. due to changes in the mood, behavior, and diet of an individual during fasting period, the body's internal homeostasis is affected. the aim of the present study was to evaluate the effects of ramadan fasting on l...
background: a radioprotective effect of amifostine as well as its ability to modulate the level of spontaneous and gamma-irradiation-induced genetic changes on human peripheral blood lymphocytes has been investigated . amifostine, known as a potent radical scavenger, has been introduced as the most effective radioprotector, yet it is not completely approved for the clinical use. however, furthe...
background: although the pathogenesis of diabetes type 1 (t1d) is not fully elucidated. different clusters of lymphocytes such as cd4+ and cd8+ t cells are involved in it. moreover, the mechanism of how stem-cell therapy results in significant therapeutic outcomes in diabetes remains obscure. in the current study, we aimed to analyze lymphocyte subsets in patients with t1d before and after trea...
there are more than 350 million individuals with hepatitis c in the world. one of the important problems in vaccine project is development of effective and suitable adjuvant in human vaccines. at present research we applied human βhsp90 protein as an adjuvant in recombinant hcv vaccine design. the thermal vector of pgp1-2 was used for human heat shock protein 90 expression. this protein injecte...
ionizing radiation causes dna damage and chromosome abbreviations on normal cells. the radioprotective effect of celecoxib (clx) was investigated against genotoxicity induced by ionizing radiation in cultured human blood lymphocytes. peripheral blood samples were collected from human volunteers and were incubated at different concentrations at 1, 5, 10 and 50 μm of clx for two hours. at each do...
The aim of the paper is to investigate effects of long term x-ray exposure on the human lymphocyte, reactive lymphocyte parameters and morphology of lymphocytes in x-ray technicians at Kirkuk hospitals. The study included 54 apparently healthy male x-ray technicians were matched with another 54 apparently healthy control to show any alteration in the lymphocytes, reactive lymphocytes and morpho...
background: critical macromolecules of cells such as dna are in exposure to damage of free radicals that induced from the interaction of ionizing radiation with biological systems. selenium and vitamin-e are natural compounds that have been shown to be a direct free radical scavenger. the aim of this study was to investigate the radioprotective effect of selenium and vitamin-e separately and sy...
introduction: the aim of this study was to evaluate the neutrophil-to-lymphocyte ratio (nlr), platelet-to-lymphocyte ratio (plr), and mean platelet volume (mpv) in patients with recurrent aphthous stomatitis (ras). materials and methods: eighty patients who were diagnosed with ras between january 2014 and january 2016 were included in this study. eighty age- and gender-matched healthy subject...
few studies have been conducted on the causative factors associated with the development of cancer. infection by high risk human papillomaviruses (hpvs) have been implicated as causative agents in a variety of cancers. hpv is capable of evading immune system and establishing persistent infections. prolonged infection and lesion maintenance are associated with higher risk of neoplastic progressi...
background: boron and gadolinium are among the nuclides that hold a unique property of being a neutron capture therapy agent. neutron beams have often a considerable portion of gamma rays with fast neutrons. gamma rays, as beam contaminants, can cause considerable damage to normal tissues even if such tissues do contain high boron concentrations. materials and methods: the modification of radio...
