We investigated coliphages from various fecal sources, including humans and animals, for microbial source tracking in South Korea. Both somatic and F+-specific coliphages were isolated from 43 fecal samples from farms, wild animal habitats, and human wastewater plants. Somatic coliphages were more prevalent and abundant than F+ coliphages in all of the tested fecal samples. We further character...

OBJECTIVES Disruption of the intestinal microbiota is considered an etiological factor in pediatric functional constipation. Scientifically based selection of potential beneficial probiotic strains in functional constipation therapy is not feasible due to insufficient knowledge of microbiota composition in affected subjects. The aim of this study was to describe microbial composition and divers...

BACKGROUND Aneurysms of the posterior cerebral artery (PCA) are rare and often associated with anterior circulation aneurysms. The lateral supraorbital approach allows for a very fast and safe approach to the ipsilateral lesions Circle of Willis. A technical note on the successful clip occlusion of two aneurysms in the anterior and posterior Circle of Willis via this less invasive approach has ...

Background: Maintaining genetic variability in livestock is the important step towards developing appropriate management strategies. When considering crossing native Lithuanian Black and White cattle (BW) with Holsteins (HL), comprehensive knowledge of breed characteristics, including diversity, required. The aim this study was to determine between Holstein breeds relation groups different prop...

In Asia, enthesitis-related arthritis (ERA) is the most frequent category of juvenile idiopathic arthritis. ERA has a strong association with human leucocyte antigen (HLA)-B27 and subclinical gut inflammation. In an HLA-B27 transgenic rat model, the presence of Bacteroides bacteria in the gut appears to cause spondyloarthropathy (SpA). Thus, we studied gut microbiota in children with ERA. Stool...

Elymus nutans and Elymus sibiricus are two important perennial forage grasses of the genus Elymus, widely distributed in high altitude regions of Western and Northern China, especially on the Qinghai-Tibetan Plateau. Information on phenotypic and genetic diversity is limited, but necessary for Elymus germplasm collection, conservation, and utilization. In the present study, the phenotypic and g...

BACKGROUND Members of the Roseobacter clade which play a key role in the biogeochemical cycles of the ocean are diverse and abundant, comprising 10-25% of the bacterioplankton in most marine surface waters. The rapid accumulation of whole-genome sequence data for the Roseobacter clade allows us to obtain a clearer picture of its evolution. METHODOLOGY/PRINCIPAL FINDINGS In this study about 1,...

PURPOSE To determine the sensitivity, specificity, and positive and negative predictive values of transcranial color-coded duplex sonographic (TCCD) evaluation of cross flow through the anterior (ACoA) and posterior (PCoA) communicating arteries in patients with occlusive cerebrovascular disease. METHODS We studied prospectively 132 patients (37 women, 95 men; mean age, 60 years) with stenose...

BACKGROUND AND PURPOSE The purpose of the present study was to assess whether the direction of flow via the circle of Willis (CoW) changed after stenting for severe internal carotid artery (ICA) stenosis. METHODS 65 patients (38 men, mean age 63.2 +/- 8.4 years, range 44-82) with a symptomatic ICA occlusion were investigated. Magnetic resonance angiography was performed prior to and 1 week af...

study of genetic relationships is a prerequisite for plant breeding activities as well as for conservation of genetic resources. in the present study, genetic diversity among and within 15 iranian native ajowan(carum copticum l.) populations were determined using inter simple sequence repeat (issr) markers. twelve selected primers produced 153 discernible bands, with 93 (60.78%) being polymorph...
