background: with the growing trend of unhealthy behaviors in the community, the likelihood of transmission of hepatitis b virus from infected people to society is increasing. so, early detection for preventing disease progression in patients and preventing the spread to the community has an important role. the aim of this study is assessment of risk factors in patients with chronic hepatitis b ...

the aim of this study is to investigate the relationship between parental attachments with preschool children's attachment classification and to determine whether there is a relation between the mother’s personality traits such as depression, extroversion, flexibility, desirability and conscientiousness, and the children’s attachment classification. method: this study is non experimental a...

metabotropic glutamate receptors (mglurs) consist of a large family of g-protein coupled receptors that are critical for regulating normal neuronal function in the central nervous system. the wide distribution and diverse physiological roles of various mglur subtypes make them highly attractive targets for the treatment of a number of neurological and psychiatric disorders. the discovery of sub...

introduction: nowadays, hiv is mostly spreading in asian countries. one of the important routes for hiv transmission in these countries is the vertical route which infects 35% to 45% of newborns. mother’s education, drug prophylaxis and cesarean section, accompanied by banning breastfeeding will decrease this rate to 2%. therefore, mothers’ knowledge about prevention of mother to child transmis...

In this paper, optimization of the sound transmission loss of finite rectangular anisotropic laminated composite plate with simply supported boundary conditions has been developed to maximize transmission loss. Appropriate constraints were imposed to prevent the occurrence of softening effect due to optimization. For this purpose, optimization process was incorporated into comprehensive finite ...

abstract due to transmission losses and lack of initial flow, flood routing in ephemeral streams is not possible with common methods and it is necessary the flood routing models have been developed for these streams. therefore in this study a computer model for natural river cross section has been developed in that after linearization of partial differential equations of unsteady none uniform f...

in this paper the effects of transmittance, dispersion angle and diffusion length on the quantum efficiency of solar cells (qesc) have been simulated and investigated. optical path technic is used for simulation. the results show that base thickness, diffusion length, dispersion angle, number of optical confinement path and transmission angles have an extremely effects on the qesc. simulation r...

background and objectives : mycoplasma hominis and ureaplasma urealyticum are important opportunistic pathogens that cause urogenital infections and accelerated newborn delivery in pregnant women. moreover genital mycoplasmas have been implicated in different neonatal diseases such as pneumonia, sepsis and meningitis. this study was conducted to find out the prevalence and transmission rate of ...

objective(s): the present study aims to study the alteration of glutamatergic transmission in the dorsal horn neurons and the effect of gabapentin on oxaliplatin-induced neuropathic pain in rats. materials and methods: oxaliplatin (5 mg/kg) or saline was administered to adult male sprague-dawley rats.  gabapentin (60 mg/kg, ip) or vehicle was injected daily. mechanical allodynia was assessed us...

background: welding can produce dangerous fumes containing various metals especially carcinogenic ones. occupational exposure to welding fumes is associated with lung cancer. therefore, welders in gas transmission pipelines are known as a high-risk group. this study was designed to determinate the amounts of metals cr, ni, and cd in breathing zone and urine of welders and to assess the possibil...
