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 ...

background: nowadays, the immune response to hepatitis c (hcv) treatment has become a crucial issue mostly due to the interleukin 28b (il-28b) polymorphism effects in chronic hcv patients. the aim of this study was to detect the polymorphism of il-28b gene (rs12979860) in hcv genotype 1 patients treated with pegylated interferon and ribavirin. methods: from the 2010 to 2012, a total of 115 peri...

introduction: one of the most common pathologies in neonates is hyperbilirubinemia, which is a good marker for damage to the central nervous system. the sensitivity of the auditory system to bilirubin has been previously documented, with much discrepancy in its effects on auditory brainstem response results. thus the objective of this study was to evaluate the effects of hyperbilirubinemia on a...

introduction: the hallmark of vitiligo is the disappearance of melanocytes from the skin due to an as yet unidentified mechanism. the presence of melanocytes in the auditory apparatus suggests that this system could possibly be affected by vitiligo, which targets the melanocytes of the whole body and not just the skin.the purpose of this study was to assess the incidence of auditory alterations...
