the objective of the present study was to evaluate the effect of metal mobilizing agents, ethelynediaminetetraacetic acid (edta) and salicylic acid (sa), on the accumulation and translocation of lead (pb) and nickel (ni) by fenugreek ( trigonellafoenum-graecum l . ) plants in contaminated soil. edta and sa were amended at 100 mm and 1.0 mm respectively. pb and ni content were estimated using ic...
conclusions pressure support ventilation, but not spontaneous breathing, induces a significant redistribution of ventilation towards the ventral region. the sensitivity of the support trigger appears to influence the distribution of ventilation only during the early phase of inspiration. background in supine position, pressure support ventilation causes a redistribution of ventilation towards t...
caspian kutum, rutilus frisii kutum, is one of the most commercially important fish species in the caspian sea, but there are few reports about the endocrinology of induced spawning in this fish. in the present study, 54 individuals of female broodstocks of kutum were studied for quantity and quality of propagation index, during march and april 2007. hormone treatments include: lhrh-a2 (1 ?g kg...
let $v$ be an $n$-dimensional complex inner product space. suppose $h$ is a subgroup of the symmetric group of degree $m$, and $chi :hrightarrow mathbb{c} $ is an irreducible character (not necessarily linear). denote by $v_{chi}(h)$ the symmetry class of tensors associated with $h$ and $chi$. let $k(t)in (v_{chi}(h))$ be the operator induced by $tin text{end}(v)$. the...
conclusions both dexmedetomidine and esmolol can be used as agents to control hypotension in patients undergoing lumbar spine decompression and fixation surgery; the dexmedetomidine group, however, was associated with better intraoperative hemodynamic stability and reduced intraoperative analgesic and volatile anaesthetic requirement. results the study results showed that dexmedetomidine had lo...
background: taxi drivers have the most important role in the public transport services. they are exposed to various harmful agents and occupational hazards. noise is a harmful occupational factors and hearing loss is its most important effect. protection of drivers against hearing loss is essential. this study was performed to determine the prevalence of hearing loss among taxi and agency drive...
conclusions despite rising figures of reported occupational hearing loss, working nbii statistics show that the nihl problem in the danish work environment has, in fact, decreased. in our study, we found that roughly one third (around 100 cases) of the 272 screened persons presumably had nihl, taking into account 88 probable cases (column b) and 44 questionable ones (column c + 16 ski slopes). ...
background: noise can cause permanent or temporary hearing loss. high levels of noise may stimulate the vestibular system and thereby cause disturbances in the balancing mechanism. objective: to determine the effect of long-term exposure to occupational noise on the vestibular system. methods: a dizziness questionnaire was administered to 20 factory workers who were exposed to occupational nois...
abstract background: hypertensive disorders in pregnancy are the main cause of maternal and fetal mortality; however, they have no definite effective treatment. the researchers aimed to study the effects of progressive muscular relaxation and breathing control technique on blood pressure (bp) during pregnancy. materials and methods: this three‑group clinical trial was conducted in mashhad healt...
introduction: previously, we demonstrated that i.p. injection of aqueous extract prepared from aerial parts of drosera spatulata (droseraceae) can induced remarkable analgesia in both phases of formalin test in rats. because, analgesia induced in acute phase of formalin test mainly mediated by activation of central analgesic mechanisms and also paragigantocellularis (pgi) nucleus is part of bra...
