background: it is clear that helicobacter pylori (h. pylori) is a spiral bacterium that infects human and causes gastritis and peptic ulcer. the aim of this study was to determine the relationship between h .pylori infection and the iron status of the body. methods: this study was conducted in shahid beheshti hospital of babol university of medical sciences, babol, iran from august 2007 to july...

backgrounds and aims: thyroid hormones have a crucial physiological role to maintain balance of metabolism of body. thyroid hormones have an important role in metabolism and proliferation of blood cells. thyroid gland also has a vital influence on erythropoiesis by induction of erythropoietin secretion and proliferation of erythroid progenitors. in the present study, it was tried to evaluate th...

in this research, the magnetite nanoparticles (fe304) were prepared by coprecipitation of fe3+ andfe solution in alkaline medium. two kinds of surfactants, cetyl tri methyl ammonium bromide(ctab) and cetyl pyridinum chloride (cpc) were used in the synthesis. fe304 nanoparticles werecoated with human serum albumin (hsa) and bovine serum albumin (bsa). characteristics ofcoated magnetic nanopartic...

background and objectives: the magnetotactic bacterium magnetospirillum gryphiswaldense (msr-1) mineralizes the magnetite (fe3 o4) crystals and organizes a highly ordered intracellular structure, called the magnetosome. iron transport system supports the biogenesis of magnetite. although iron is an essential trace element for many metabolic pathways of the body, increase or decrease in iron wil...

background oxidative stress plays a major pathogenic role in liver injury following chronic hepatitis b. glutathione peroxidase (gpx) has a central role in regulating the oxidative state. hepatitis b virus (hbv) results in down-regulation of gpx. on the other hand, iron homeostasis is disrupted in hbv infected patients. therefore, the objective of this study was to assess the interplay of gpx a...

background: iron is an essential mineral for normal cellular physiology but its ‎overload can lead to cell injury. for many years, deferoxamine injection has been used ‎as an iron chelator for treatment of iron overload. the aim of this study is to compare ‎oral deferoxamine, activated charcoal, and vitamin c, as an absorbent factor of fe, in ‎changing the serum level of iron in iron overload r...

objective: breath holding spells, very often misinterpreted as epileptic seizures, are most common in children aged 6 months to 6 years of age. in this investigation, we sought to prospectively document the natural history of breath holding spells (bhs) among children with cyanotic, pallid and mixed type bhs referred for neurological consultation. materials & methods: this was a cross-sectional...

background: a close relationship has been reported between level of serum iron and ischemic heart diseases which is either brought about through direct effect of serum iron on myocardial cells or as an indirect result of elevated serum lipid profile. a widespread use of iron supplements has been observed due to the high prevalence of iron deficiency anemia. yet an elevated serum lipid is strong...
