background: the goal of the present study was to report the results of two parallel works in which the incidence of fetal deaths and also congenital malformations among the progenies of the iranian chemical victims were studied. methods: the subjects were progenies of a randomly selected population from survivors of chemical attacks during iran-iraq conflict. totally 807 male cases ranged 18-85...
cobalt ferrite (cofe2o4) nanorods were synthesized by iron chloride (fecl3.6h2o) and cobalt sulfate hexahydrate (coso4.7h2o) as precursor in the presence of ethylene glycol agent and poly vinyl pyrrolidone (pvp) surfactant. the samples were characterized to identify the physical properties. xrd pattern of cobalt ferrite samples showed the structure of body center cubic (bcc) structure. the diam...
acanthamoeba keratitis (ak) is a sight-threating infection of the cornea that mostly affects contact lens wearers. until now, ak treatment remains very difficult due to the existence of a highly resistant cyst stage in the life cycle of acanthamoeba which is extremely resistant to most of the available anti-amoebic compounds. moreover, current treatment of ak is usually based in the combination...
aims: in the past few decades, more attention has been paid to clean up soils polluted with heavy metals by plants. a serious problem in this way is the amount of heavy metals uptake by plants. this study was conducted to evaluate the effectiveness of 3 local plants of mazandaran province, iran, in reducing and controlling the soil’s heavy metals. instrument & methods: the removal amount of thr...
the aetiology behind odor-related chronic somatic symptoms (o-rcss) is unknown, although both immunological and psychiatric causes have been suggested. the aim of this study was to investigate the occurrence of self-reported asthma and hay fever and psychiatric symptoms in individuals having o-rcss compared to individuals with similar chronic somatic symptoms (css) which were not odors-related,...
sulfur mustard has been employed in chemical warfare in certain regions including iran. the short and long term biological effects of sulfur mustard contamination have been studied in both basic and clinical aspects. sulfur mustard has been shown to induce a vast array of pathological effects in affected persons. in addition to skin, lung, eyes and gastrointestinal disturbances, sulfur mustard ...
background : the present paper aims to study the effect of human and urban activities on the quality of groundwater within the city of khoy in terms of heavy metals, chemical salts, and minerals from the geological formations of this region. methods : samples were provided from 32 pumping wells and the concentration of heavy metals ( cd, cu, mn, pb, zn, fe, as, and b), the main ions (hco 3 ,so ...
abstract pomegranate (punica granatum l.) is an important iranian-native fruit, and many of its varieties are cultivated. this research was conducted to evaluate some of the major physical and chemical properties of six pomegranate cultivars at ripening stage in a completely randomized design with 4 replications. the investigated traits were fruit fresh weight, fruit volume, peel thickness, pee...
in the present study, we investigated the variation in the content of naphthodianthrones hypericin and pseudohypericin, phloroglucinol derivatives hyperforin and adhyperforin, the phenolic acids as chlorogenic acid, neochlorogenic acid, 2,4-dihydroxybenzoic acid, and the flavonols, namely, hyperoside, isoquercitrin, quercitrin, quercetin, avicularin, rutin, (+)-catechin and (-)-epicatechin, and...
chemical hardness (), absolute electronegativity (), and electrophilicity () have importantapplications in inorganic chemistry. these concepts are defined quantitatively as � � �� � ����,� � �� � ����, � � ������where i is the ionization energy and a is the electron affinity. in thisstudy, graphical method was used to see the relation of electron configuration with chemicalhardness, absolute...
