background: whether exposure to common electromagnetic fields affects human health adversely has been a controversial issue. the main goal of this study was to assess the role of 900 mhz microwave radiations with different specific absorption rates (sars), emitted from some widely used cell phones, on the induction of adaptive response in male balb/c mice after receiving a lethal dose of gamma ...
introduction : pre-hospital emergency systems provide service by franco-german and anglo american models. this study was carried out to compare the iranian emergency medical service (ems) with the two models regarding timing and equipment. methods : in this cross sectional study, response time, scene time, and transport time to hospital as well as ambulance equipment of five hundred thousand te...
the functional response of a predator is the base of prey-predator dynamics. functional response of serangium montazerii fã¼rsch at different egg densities (50, 100, 150, 200 and 250) of dialeurodes citri (ashmead) was studied in an open-patch experiment, in a growth chamber (25 â± 1â°c, 65 â± 5% rh and a photoperiod of 16: 8 l: d h) on âthompsonâ navel orange (citrus sinensis cv. thompson)...
failure to respond adequately to standard protocols and to recruit adequate follicles is called ‘poor response’. this results in decreased oocyte production, cycle cancellation and, overall, is associated with a significantly diminished probability of pregnancy. it has been shown that ovarian reserve tests, such as basal fsh, antimullarian hormone (amh), inhibin b, basal estradiol, antral folli...
background and aim: the sexual hormones alter during menstrual cycle and pregnancy. despite the physiological benefits of these changes, their adverse effects on hearing system such as hearing loss and vertigo have been reported. therefore, in this study, the auditory brainstem responses (abr) were investigated during physiological hormonal variations in the menstrual cycle as well as pregnancy...
aspergillus species (a flavus and a niger) are important sources of inhalant allergens. current diagnostic modalities employ crude aspergillus extracts which only indicate the source to which the patient has been sensitized, without identifying the number and type of allergens in crude extracts. we report a study on the identification of major and minor allergens of the two common air...
introduction the purpose of the current study was to determine optical sensitivity of n-isopropyl acrylamide nipam and polyacrylamide gelatin and tetrakis hydroxymethyl phosphoniun chloride (pagat) polymer gels for different wavelength of visible light spectrum applied in optical computed tomography method. materials and methods nipam and pagat polymer gels with conventional formulations used f...
in order to reduce the costs associated with poly-β-hydroxybutyrate production, growth and poly-β-hydroxybutyrate production of ralstonia eutropha were studied in batch culture on different carbon sources. experiments were designed and conducted to not only lower the cost of poly-β-hydroxybutyrate production by using inexpensive substrates, but also to increase poly-β-hydroxybutyrate production...
background sepsis is one of the most important causes of morbidity and mortality in the intensive care units (icus). it is difficult to accurately differentiate sepsis from similar diseases rapidly. therefore, it becomes critical to identify any biomarker with the ability of differentiation between sepsis and nonsepsis conditions. the urokinase plasminogen activator receptor has been implicated...
background: the effect of low dose radiation on immune system is shown. ionizing radiation can affect cytokine production and polarization of t helper cells. objective: the current study focused on ionizing radiation in ukrainian children residing in a contaminated area with clinical irritable bowel syndrome. method: our study included 75 rural children population aged 4-18 yrs, who lived in a ...
