Background The presence of different missense mutations in sheep breeds have shown that the bone morphogenetic protein receptor 1B (BMPR1B), bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9) genes play a vital role in ovulation rate and prolificacy in ewes. Therefore, the present study aims to investigate BMPR1B, BMP15 and GDF9 gene mutations in prolific ewes of I...

Escherichia coli, an opportunistic environmental pathogen, is one of the commonest causes of bovine clinical mastitis in the early lactation period. Shiga toxin-producing E. coli (STEC) whose pathogenesis is associated with enterotoxigenic genes (stxI, stxII, and eaeA) cause serious acute illness and long-term side effects in both animals and humans. The aim of this study was to investigate the...

conclusions chaharmahal and bakhtiari province could be categorized as a low endemic region for hepatitis b infection, with a seroprevalence similar to that in other provinces of western iran. vaccination seems to influence its decrease, especially in adolescents and youth. more surveillance and attention to risk factors are suggested to identify high-risk groups and to implement vaccination. r...

OBJECTIVE Keratoconus (KC) is an eye disorder in which the cornea is swollen, thinned and deformed. Despite extensive studies, the pathophysiological processes and genetic etiology of KC are unknown. The disease incidence is approximately 1 in 2,000, and it is the most common cause of corneal transplantation in the USA. Many genes are involved in the disease, but evidence suggests a major role ...

To accommodate major civil engineering projects in or in the vicinity of peatlands, it is essential to stabilise peat deposits. On the other hand, the accumulation of waste tyres in recent decades has caused environmental problems around the world. An effective remedy for both issues is to use scrap tyre material to stabilise problematic peat soils. This article reports an experimental investig...

Ephedra prcera belonging to the family Ephedraceae is a poison and medicinal plant. The main aim of present study was to determine total phenolic content and antioxidant and antibacterial activities of ethanolic extract from the aerial parts of E. procera collected from a natural habitat in Chaharmahal va Bakhtiari province, Southwestern Iran. The total phenolic content of the extract by Folin-...

Water quality is a key environmental issue concerning the agricultural sector. Here, the application of fuzzy set theory for decision-making in the assessment of groundwater quality for agricultural purposes is being discussed. The experiments conducted in this study area located, Shahrekord plain that, lies in the Chaharmahal and Bakhtiari province, in the southwest Iran. Four groundwater para...

As I read the study by Bakhtiari et al. (1), I noticed that they miscalculated the positive predictive value. They indicated that the positive predictive value of the PCR assay was 100%. But when I placed the values on the table and calculated the positive predictive value of the PCR assay, I found it 83.3%.

Background and aims: There are different causes for brain death including head trauma, cerebrovascular accidents and intracranial space-occupying lesions. The present study was aimed to determine the causes of brain death in Chahar Mahal and Bakhtiari province due to high turnover of trauma in this area during 2003 to 2013...

Bakhtiari et al recently proposed a fast message authentica-tion primitive called KHF. This paper shows that KHF is highly vulnerable to diierential cryptanalysis: it can be broken with about 37 chosen message queries. This suggests that the KHF design should be reconsidered .
