There is a need for robust and accurate techniques for the measurement of ammonia (NH3) and other atmospheric pollutant emissions from poultry production facilities. Reasonable estimates of NH3 emission rate (ER) from poultry facilities are needed to guide discussions about the industry's impact on local and regional air quality. The design of these facilities features numerous emission points ...

Vehicle exhaust emissions have posed a serious threat in recent years to the urban air quality of Beijing. It is necessary to accurately estimate the magnitude and distribution of these emissions in order to reduce the uncertainty of local scale air quality modeling assessment. This paper provides a bottom-up approach by combining vehicle emission factors and vehicle activity data from a travel...

Objective: Fragile X syndrome is the second etiology for inherited mental retardation. It may concomitant with other psychiatric disorders. Intellectual disability (ID) is a state of functioning that typically begins in childhood and is characterized by limitations in intelligence and adaptive skills. We intend to introduce a male young patient with Fragile X syndrome and Obsessive-Compulsive d...

objectives: dependence and tolerance are major restricting factors in the clinical use of opioid analgesics. in the present study, the effects of thymoquinone, the major constituent of nigella sativa seeds, on morphine dependence and tolerance were investigated in mice. materials and methods: male adult nmri mice were made tolerant and dependent by repeated injections of morphine (50, 50, and 7...

Background Single nucleotide polymorphism (SNPs) are considered as one of the underlying causes of male infertility. Proper sperm chromatin packaging which involves replacement of histones with protamines has profound effect on male fertility. Over 20 SNPs have been reported for the protamine 1 and 2. MaterialsAndMethods The aim of this study was to evaluate the frequency of two previously repo...

The aims of the present study were to evaluate luteal activity in Abadeh ecotype goat during summer and winter and also the effect of a single dose kisspeptin-10 injection on the secretion of luteinizing hormone (LH) in female anestrous goats. In the first study, progesterone (P4) concentration in 10 goats in summer (n = 6) and winter (n = 4) were measured every other day. Moreover, ...

Several studies have investigated the association between polymorphisms in protamine 1 and 2 genes and male infertility risk, with inconsistent results to date. This meta-analysis based on the 13 published case-control studies, including 7350 cases and 6167 controls, was performed to further establish the potential association between the 6 common single nucleotide polymorphisms (rs35576928, rs...

INTRODUCTION The otoacoustic emission test is useful in monitoring hearing changes not yet detectable in pure-tone audiometry, as well as in monitoring cochlear damage caused by exposure to noise. OBJECTIVE To evaluate distortion product otoacoustic emissions in normal-hearing workers exposed to different occupational noise doses. MATERIALS AND METHOD This is a cohort prospective study perf...

Objective Contralateral suppression of oto acoustic emission (OAE) is referred as activation of efferent system. Previous literature mentioned about the importance of contralateral suppression of OAEs as a tool to assess efferent system in different groups of population. There is dearth of literature to explore the efferent system function in experienced musicians exposed to rock music using TE...
