Comparison of bacterial diversity along the human intestinal tract by direct cloning and sequencing of 16S rRNA genes

Bacterial diversity of the mucosal biopsies from human jejunum, distal ileum, ascending colon and rectum were compared by analysis of PCR-amplified 16S rDNA clone libraries. A total of 347 clones from the mucosal biopsies were partially sequenced and assigned to six phylogenctic phyla of the domain Bacteria: Firmicutes, Bacteroidetes, Proteobacteria, Fusobacteria, Verrucomicrobia, and Actinobacter

The association between caregiving satisfaction, difficulties and coping among older family caregivers.

Aims and objectives. The aim was to study the association between gender, extent and content of care, satisfaction, coping and difficulties in the caregiving situation among older (75+) caregivers and to identify clusters of caregivers. The aim was also to explore psychometrically two instruments assessing satisfaction and difficulties in family caregivers. Background. Caregiving is a complicated

Modelling of Biomass Combustion in Furnaces

Biomass combustion in grate fired furnaces is an important approach to convert renewable biomass fuel to heat and electricity. It is not only used in the Swedish energy industry but also by a great number of Swedish households for domestic heating. Burning biomass has the advantage of being CO2 neutral. However, it suffers from several difficulties, for example, the poor combustion efficiency ? th

Ethnicity and obesity: Evidence of automatic work performance stereotypes in Sweden

Using the Implicit Association Test, we investigate whether employers and students possess implicit and explicit negative attitudes and implicit perform-ance stereotypes toward Arab-Muslim men relative to native Swedish men. We also examine if employers and students have implicit and explicit performance stereotypes toward obese individuals relative to people of normal weight. The results demonstr

Time domain Green functions for the homogeneous Timoshenko beam

In this paper a wave splitting technique is applied to a homogeneous Timoshenko beam. The purpose is to obtain a diagonal equation in terms of the split fields. These fields are calculated in the time domain from an appropriate set of boundary conditions. The fields along the beam are represented as a time convolution of Green functions with the excitation. The Green functions do not depend on the

Virtual reality therapy versus cognitive behavior therapy for social phobia: A preliminary controlled study

Social phobia is one of the most frequent mental disorders and is accessible to two forms of scientifically validated treatments: anti-depressant drugs and cognitive behavior therapies (CBT). In this last case, graded exposure to feared social situations is one of the fundamental therapeutic ingredients. Virtual reality technologies are an interesting alternative to the standard exposure in social

The ADP receptor P2Y(1) mediates t-PA release in pigs during cardiac ischemia.

Background The endothelial ADP receptor P2Y(1) is responsible for a large part of the reactive hyperemia following cardiac ischemia. Tissue plasminogen activator (t-PA) increases during reactive hyperemia. We postulated that the release of t-PA during reactive hyperemia could be mitigated through blocking the coronary endothelial P2Y(1) receptor. Methods t-PA was measured in peripheral arterial bl

Development of analysis tools and stochastic models of road profiles regarding their influence on heavy vehicle fatigue

Road profiles are analyzed with focus on road characteristics essential for heavy vehicle fatigue assessment. Road profile measurements indicate that roads contain short sections with above-average irregularity. Such rough sections are shown to cause most of the vehicle fatigue damage. An algorithm using a spatial-frequency description is developed to automatically identify rough sections. On the

TinyRealTime - An EDF Kernel for the Atmel ATmega8L AVR

This report describes the design and implementation of {TinyRealTime}, an event-based real-time kernel for the Atmel AVR ATmega8L 8-bit micro-controller. The kernel is event-based and supports fully preemptive earliest-deadline-first scheduling of tasks. Semaphores are provided to support task synchronization. The focus of the report is on the memory management, timing, and internal workings of th

Ultrastructure and functional organization of mouthpart sensory setae of the spiny lobster Panulirus argus: New features of putative mechanoreceptors

In comparison with other decapods, the Caribbean spiny lobster Panulirus argus has little diversity in the external morphology of the setae on the mouth apparatus. In mouthpart areas that frequently touch food items only two types of setae can be distinguished: simple setae and cuspidate setae. Simple setae are by far more numerous. The ultrastructural data presented here show that both types of s

Vad ska vi med kunskapsöversikter till?

Forskarna Eva-Malin Antoniusson, Arne Kristiansen, Leili Laanemets, Bengt Svensson och Dolf Tops har granskat skriften Sprututbyte – En genomgång av den internationella forskningen och den svenska debatten (Fri förlag 2005) och menar att det är ett exempel på en starkt politiserad kunskapsöversikt.

C1-TEN is a negative regulator of the Akt/PKB signal transduction pathway and inhibits cell survival, proliferation, and migration

We have previously identified C1 domain-containing phosphatase and TENsin homologue (C1-TEN) as being an intracellular binding partner for Axl receptor tyrosine kinase (RTK). C1-TEN is a tensin-related protein that houses an N-terminal region with predicted structural similarity to PTEN. Here, we report our observations on the effects of ectopic expression of C1-TEN in HEK293 cells, which resulted

Enantioselective formal synthesis of tridemethylisovelleral

A simple and efficient synthetic route to the bicyclic alpha,beta-unsaturated beta-keto ester methyl (3aS,7aS)-6-oxo-2,3,3a,6,7,7ahexahydro-1H-indene-5-carboxylate, a versatile intermediate in the synthesis of biologically active unsaturated 1,4-dialdehydes, is described. The synthesis includes a chirality introducing nonenzymatic asymmetric desymmetrization (ADS) reaction of a cyclic nieso-anhydr
