Prebiotic-non-digestible oligosaccharides preference of probiotic bifidobacteria and antimicrobial activity against Clostridium difficile.

Bifidobacterium breve 46, Bifidobacteriumlactis 8:8 and Bifidobacteriumlongum 6:18 and three reference strains B. breve CCUG 24611, B. lactis JCM 10602, and Bifidobacteriumpseudocatenulatum JCM 1200 were examined for acid and bile tolerance, prebiotic utilization and antimicrobial activity against four Clostridium difficile (CD) strains including the hypervirulent strain, PCR ribotype NAP1/027. B.

Autoinhibition of Jak2 tyrosine kinase is dependent on specific regions in its pseudokinase domain.

Jak tyrosine kinases have a unique domain structure containing a kinase domain (JH1) adjacent to a catalytically inactive pseudokinase domain (JH2). JH2 is crucial for inhibition of basal Jak activity, but the mechanism of this regulation has remained elusive. We show that JH2 negatively regulated Jak2 in bacterial cells, indicating that regulation is an intrinsic property of Jak2. JH2 suppressed

Interface electronic states and molecular structure of a triarylamine based hole conductor on rutile TiO2(110).

The molecular and electronic surface structure of a triarylamine based hole-conductor (HC) molecule evaporated onto rutile TiO2(110) single crystal is investigated by means of synchrotron light based photoelectron spectroscopy and x-ray absorption spectroscopy in combination with calculations based on density functional theory. Different amounts of the HC molecule was evaporated spanning the monol

The Social Construction of Nationalism : Sweden as an Example

In this thesis, nationalism is seen as a discourse constructed in social relations. Although socially constructed, nationalism still seems like having an impersonal character and the nation is commonly conceived of as a holistic system within which modern political relations are embedded. The author views this discursive character as the consequence of a co-operation between relational power and a

Use, appropriateness, and diagnostic yield of screening colonoscopy: an international observational study (EPAGE)

Abstract in UndeterminedBackgroundScreening for colorectal cancer (CRC) has been shown to decrease mortality.ObjectiveTo examine determinants associated with having (1) a screening colonoscopy, (2) an appropriate indication for screening, and (3) a significant diagnosis at screening.DesignProspective observational study.SettingTwenty-one endoscopy centers from 11 countries.PatientsAsymptomatic pat

Oxytocin and cholecystokinin secretion in women with colectomy

Background: Cholecystokinin (CCK) concentrations in plasma have been shown to be significantly higher in colectomised subjects compared to healthy controls. This has been ascribed to reduced inhibition of CCK release from colon. In an earlier study CCK in all but one woman who was colectomised, induced release of oxytocin, a peptide present throughout the gastrointestinal (GI) tract. The aim of th

Harvesting Wild Boar a study of prey choice by hunters during the Mesolithic in South Scandinavia by analysis of age and sex structures in faunal remains

The hunting of wild boar during the Mesolithic was studied by analysis of age and sex distributions in faunal remains from four settlement situated in Scania, Southern Sweden. The results show that the harvest of wild boar varied between different settlements, Piglets dominate the age distribution in the faunal remains of teh sites of Ringsjöholm and Tågerup, which indicate a hunting of wild boar

Few-electron quantum dots in nanowires

We demonstrate transport spectroscopy on bottom-up grown few-electron quantum dots in semiconductor nanowires. The dots are defined by InP double barrier heterostructures in InAs nanowires catalytically grown from nanoparticles. By changing the dot size, we can design devices ranging from single-electron transistors to few-electron quantum dots. In the latter case, electrons can be added one by on

Biological and molecular evidence for existence of lymphoid-primed multipotent progenitors

Studies from our and other laboratories have over the last 2 years implicated the existence of multipotent progenitors (MPPs) with combined granulocyte-macrophage, B cell, and T cell potential, but little or no megakaryocyte-erythroid (MkE) potential in the adult bone marrow Lineage (-)SCA-1 +KIT+ (LSK) compartment of multipotent stem and progenitor cells. The evidence for the existence of LSKCD34

Prevalence of carpal tunnel syndrome in a general population

CONTEXT: Carpal tunnel syndrome (CTS) is a cause of pain, numbness, and tingling in the hands and is an important cause of work disability. Although high prevalence rates of CTS in certain occupations have been reported, little is known about its prevalence in the general population. OBJECTIVE: To estimate the prevalence of CTS in a general population. DESIGN: General health mail survey sent in Fe

Cystatin C in the anterior segment of rat and mouse eyes.

Purpose: Cystatin C is a mammalian cysteine protease inhibitor. This study describes the localization of cystatin C in the anterior segment of normal rat and mouse eyes. Cysteine proteases play an important role in protein degradation (e.g. of photoreceptor outer segments in the retinal pigment epithelium) and the balance between these proteases and their specific inhibitors is therefore of great

Wave splitting in the time domain for a radially symmetric geometry

A decomposition of the field of the wave equation in three dimensions is suggested. This wave splitting decomposes the field into two components such that in free space simple propagation properties are obtained. The inhomogeneous region is assumed to have a phase velocity variation that varies only in the radial coordinate r from the origin. The suggested wave splitting is a generalization of the
