Background: A major part of medical pathology in internal medicine is associated with chronic alcoholism. The aim of the current study was to investigate whether screening for Alcohol Use Disorders (AUD) can be improved through determination of direct ethanol metabolites compared to traditional biological state markers, the Alcohol Use Disorders Identification Test (AUDIT) and additional self-repo
Type 1 diabetes is one of the most common chronic diseases in childhood and adolescence with an increasing incidence worldwide. It is an autoimmune disease with many autoimmune markers, where the zinc transporter 8 autoantibody (ZnT8A) is the most recent autoantibody discovered. The most important genetic susceptibility towards type 1 diabetes is found within the HLA-region on chromosome 6. We sho
The role of the intermediate filament protein desmin in hypertrophy of smooth muscle was examined in desmin deficient mice (Des -/-). A partial obstruction of the urethra was created and after 9-19 days bladder weight increased about 3-fold in both Des -/- and wild type (Des +/+) animals. Bladder growth was associated with synthesis of actin and myosin. In the hypertrophic Des +/+ bladder the rela
Popular Abstract in Swedish Bröstcancer är den vanligaste cancerdiagnosen hos svenska kvinnor, ca 8000 tumörer diagnosticeras årligen. Vid rekommendation om behandling till patienter med nyupptäckt bröstcancer utgår man från ett antal prognostiska (risk för återfall och död utan behandling) och prediktiva (risk för återfall och död med specifik behandling) faktorer. Ålder, tumörstorlek, cancercellBreast cancer is a heterogeneous disease with variations in the biological profile and subsequent clinical prognosis. Molecular mechanisms for tumour progression are currently being explored in scientific settings, suggesting parallel evolution of tumour cells at primary and metastatic locations. The molecular profiles could be altered affecting individual patient’s treatment and prognosis. In the
Swedish has – like other Germanic languages – flexible stress placement, which underlies morphological rules and is also based on the individual word’s origin. The achievement of the correct usage when learning Swedish is challenging. As second language learners of Swedish in the classrooms present speakers of a variety of first languages (L1s), the opportunity has been taken to have a closer look
Photochemical reactions rationalization is a key aspect for the understanding and setup of novel experiment and novel photoinitiated pathways. In this respect, the relationship between minimum energy paths over an excited-state and the intersection to lower potential energy surfaces is fundamental. In order to help the understanding of this relationship, in this study we present a novel kind of co
Ferrochelatase (EC 4.99.1.1) catalyzes the last reaction in the heme biosynthetic pathway. The enzyme was studied in the bacterium Bacillus subtilis, for which the ferrochelatase three-dimensional structure is known. Two conserved amino acid residues, S54 and Q63, were changed to alanine by site-directed mutagenesis in order to detect any function they might have. The effects of these changes were
Interactions between transmembrane helices play a key role in almost all cellular processes involving membrane proteins. We have investigated helix-helix interactions in lipid bilayers with synthetic tryptophan-flanked peptides that mimic the membrane spanning parts of membrane proteins. The peptides were functionalized with pyrene to allow the self-association of the helices to be monitored by py
The existence and mode of selection operating on heritable adaptive traits can be inferred by comparing population differentiation in neutral genetic variation between populations (often using F-ST values) with the corresponding estimates for adaptive traits. Such comparisons indicate if selection acts in a diversifying way between populations, in which case differentiation in selected traits is e
Statins are inhibitors of the rate-limiting step of cellular cholesterol synthesis. In vitro and in vivo studies suggest that statins have anti-inflammatory properties independent of their cholesterol-lowering effects. These observations prompted us to examine the effects of pravastatin (50 mgr; M) and native or oxidized low density lipoprotein (nLDL or oxLDL) (50 mgr; g ml(minus sign1)) on primar
In this study the effect of different times of exposure to ethanol (1-7 days, 100 mM) on bradykinin and GTP(S)-stimulated activation of phospholipase C in NG 108-15 cells and on the binding of [3H]bradykinin to its receptors was investigated. Ethanol attenuated both agonist and GTP-analogue-induced hydrolysis of phosphoinositides for a period of up to 4 days of treatment, while exerting no effect
Aims/hypothesis: Little is known about the heritable basis of gene–environment interactions in humans. We therefore screened multiple cardiometabolic traits to assess the probability that they are influenced by genotype–environment interactions. Methods: Fourteen established environmental risk exposures and 11 cardiometabolic traits were analysed in the VIKING study, a cohort of 16,430 Swedish adu
This paper draws attention to the potential benefits of using photographs in combination with interviews, that is to say photo elicitation. As defined by Harper (2002), photo elicitation is “based on the simple idea of inserting a photograph into a research interview” (p. 13). The photographs can be taken by the researcher or the participant to evoke comments. If participants are asked to produce
Tumours displaying differentiation towards normal fat constitute the most common subgroup of soft tissue neoplasms. A series of such tumours was investigated by whole-exome sequencing followed by targeted ultra-deep sequencing. Eighty percent of angiolipomas, but not any other tumour type, displayed mutations in the protein kinase D2 (PRKD2) gene, typically in the part encoding the catalytic domai
BACKGROUND & AIMS: The abnormalities associated with cancer cachexia include anorexia, weight loss, muscle loss and atrophy, anaemia and alterations in carbohydrate, lipid and protein metabolism. The aim of the present investigation was to examine the anti-wasting effects of some nutraceuticals such as genistein, resveratrol, epigallocatechin gallate and diallyl sulphide (DAS).METHODS: The in
Most of the last 20 years in Sweden have been mild and wet compared to the 1961-1990 climate reference period. After a few relatively cold years in the mid-1980s, practically all years have been warmer than the preceding 30 years average. During the indicated period, an increase of moisture-related problems (mould growth) was observed in ventilated attics, a moisture sensitive building part.This w
