Disease gene identification is still a challenge despite modern high-throughput methods. Many diseases are very rare or lethal and thus cannot be investigated with traditional methods. Several in silico methods have been developed but they have some limitations. We introduce a new method that combines information about protein-interaction network properties and Gene Ontology terms. Genes with high

Incidence of cancer of unknown primary (CUP) varies globally, and environmental factors are suspected to be related to its development. Immigrant studies offer insights into disease etiology, but no studies have been published on CUP. We investigated CUP risk in immigrants to Sweden to search for etiological clues. The nationwide Swedish Family Cancer Database was used to calculate standardized in

Palatine tonsils are continuously exposed to microorganisms and antigens and secrete antimicrobial peptides as a first line of defense. S100A7 is a protein with antimicrobial and chemotactic properties. Our aim was to investigate how the expression of S100A7 in human palatine tonsils is affected by inflammatory processes. Tonsils obtained from 109 patients undergoing tonsillectomy were divided int

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.

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

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

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

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

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

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

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

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

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
