The T(-13910) variant located in the enhancer element of the lactase (LCT) gene correlates perfectly with lactase persistence (LP) in Eurasian populations whereas the variant is almost nonexistent among Sub-Saharan African populations, showing high prevalence of LP. Here, we report identification of two new mutations among Saudis, also known for the high(More)
An A118G nucleotide exchange in exon 1 of the mu-opioid receptor causes an Asn40Asp substitution polymorphism in the receptor's extracellular domain. In vitro studies show that the Asp40 variant of the mu-opioid receptor binds beta-endorphin three times more avidly than the more common Asn40 variant. Paraventricular corticotropin releasing hormone neurons,(More)
OBJECTIVES Autism spectrum disorder (ASD) is a developmental disorder characterized by pervasive deficits in social interaction, impairment in verbal and non-verbal communication, and stereotyped patterns of interests and activities. Vitamin-D deficiency was previously reported in autistic children. However, the data on the relationship between vitamin D(More)
Twenty-four avian influenza viruses were collected from poultry farms in three different governorates in Egypt during the years 2006–2009 and genetically characterized. All the isolates were confirmed to be type A and subtype H5 influenza virus by chromatographic strip test and hemagglutination inhibition assay. The sequence and phylogenetic data revealed(More)
In October and November 2010, novel H1N2 reassortant influenza viruses were identified from pigs showing mild respiratory signs that included cough and depression. Sequence and phylogenetic analysis showed that the novel H1N2 reassortants possesses HA and NA genes derived from recent H1N2 swine isolates similar to those isolated from Midwest. Compared to(More)
A reverse transcription-polymerase chain reaction (RT-PCR) assay for the detection of avian pneumovirus (APV), Colorado strain (US/CO), was evaluated for sensitivity and specificity. The single-tube RT-PCR assay utilized primers developed from the matrix (M) gene sequence of the US/CO APV. The RT-PCR amplified the US/CO APV but did not amplify other(More)
The aim of this study was to investigate uterine torsion in buffaloes, examine factors influencing the outcome of the disease, and to characterize the related alterations in blood constituents. A total of 126 buffaloes with uterine torsion were examined for stage of gestation, duration, degree, site and direction of torsion, as well as the location of the(More)
Pigs are capable of generating reassortant influenza viruses of pandemic potential, as both the avian and mammalian influenza viruses can infect pig epithelial cells in the respiratory tract. The source of the current influenza pandemic is H1N1 influenza A virus, possibly of swine origin. This study was conducted to understand better the pathogenesis of(More)
A reverse transcription-polymerase chain reaction assay was developed for the detection of avian pneumovirus (Colorado strain) (APV-Col). The specific primers were designed from the published sequence of the matrix protein gene of APV-Col. The primers amplified a product of 631 nucleotides from APV-Col. The assay identified only APV-Col and did not react(More)
