Objective. According to epidemiological studies, smoking habit is strongly associated with inflammatory bowel disease. Non-smokers, and especially recent ex-smokers, have an increased risk of ulcerative colitis (UC). Conversely, concerning Crohn's disease, the risk is increased among smokers. Pouchitis is the major long-term complication of restorative proctocolectomy for UC, and seems to be patho

Context: The insulin tolerance test ( ITT) is the current standard diagnostic test for the diagnosis of adult GH deficiency ( GHD), but alternative tests, such as the GHRH- arginine test, have been proposed. Objective: We investigated the sensitivity and specificity of the GHRH- arginine test using ITT as the gold standard in diagnosing GHD in a group of young adults treated with cranial irradiati

This article deals with Heideggers idiosyncratic relation to, and within German national socialism, how he saw his own position as more "authentic" than the version which ruled in Nazi Germany.

Background: Pharmacodynamic investigations with antimicrobials define the relationship between the infecting organism and achievable drug concentrations with clinical outcome. Objective: To examine this relationship for meropenem in a population of patients who are at high risk of infection-related morbidity and mortality. Methods: The study was a retrospective analysis of a multicenter, randomize

An experimental setup for objective measurements of high impedance objects in ducts, yielding the acoustical Two-Port properties of the object, is presented. The setup has been applied on earplugs. A frequently used experimental setup for measuring objective acoustical properties of earplugs is that of artificial ears. Great effort is spent duplicating the ear of a person. The insertion loss is co

PURPOSE: To assess the clinical phenotypes in three Swedish families with X-linked retinitis pigmentosa caused by different mutations in the RPGR gene. METHODS: Three families from different parts of Sweden, including nine patients with retinitis pigmentosa and six female carriers of X-linked retinitis pigmentosa, were examined clinically. Ophthalmologic examination included kinetic perimetry with

Artikeln utgör en kommentar till den så kallade kristologidebatten som ägde rum i Svenska Dagbladet under 2003.

Oscillations in the B-s(0)- <(B-s(0))over bar> system were studied in events selected from about 4.3 million hadronic Z(0) decays registered by DELPHI between 1992 and 2000. This paper presents updates of two published analyses ([11, 12]). The first analysis, which utilizes leptons emitted with large momentum transverse to a jet, was improved by means of a better algorithm for the vertex reconstuc

Background: Attempts to retrieve absolute values of cerebral blood flow (CBF) by dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) have typically resulted in overestimations. Purpose: To improve DSC-MRI CBF estimates by calibrating the DSC-MRI-based cerebral blood volume (CBV) with a corresponding T1-weighted (T1W) steady-state ( ss) CBV estimate. Material and Methods: 17 volunt

Background. The systemic and local tissue repair responses of radiation in combination with surgery are still unclear. We have studied the effect of fractionated pre-operative radiotherapy with or without subsequent laparotomy on collagen accumulation using a rodent model. Materials and methods. Thirty-two male Sprague-Dawley rats were divided into four groups (eight rats per group): 1) sham radia

Heterologous genes for xylose utilization were introduced into an industrial Saccharomyces cerevisiae, strain A, with the aim of producing fuel ethanol from lignocellulosic feedstocks. Two transformants, A4 and A6, were evaluated by comparing the performance in 4-l anaerobic batch cultivations to both the parent strain and a laboratory xylose-utilizing strain: S. cerevisiae TMB 3001. During growth

The etiology of polycystic ovary syndrome (PCOS) is unknown. However, PCOS has a strong resemblance to the insulin resistance (metabolic) syndrome, where an increased rate of visceral fat cell lipolysis is believed to play a pathophysiological role. We hypothesized that primary defects in visceral lipolysis might also exist in PCOS. Ten young, nonobese, and otherwise healthy PCOS women were compar

Supply chain risk management (SCRM) is of growing importance, as the vulnerability of supply chains increases. The main thrust of this article is to describe how Ericsson, after a fire at a sub-supplier, with a huge impact on Ericsson, has implemented a new organization, and new processes and tools for SCRM. The approach described tries to analyze, assess and manage risk sources along the supply c

Most people hold beliefs about personality characteristics typical of members of their own and others' cultures. These perceptions of national character may be generalizations from personal experience, stereotypes with a "kernel of truth," or inaccurate stereotypes. We obtained national character ratings of 3989 people from 49 cultures and compared them with the average personality scores of cultu

The effect of postharvest long-term storage and pre-treatments on the mass transfer rates during osmotic dehydration of carrots was investigated. Four blanching times were used and the carrots were sampled during 12 weeks of storage. Cell vitality was measured by isothermal calorimetry on cores taken from blanched slices. During the storage period, effective diffusion coefficients for water and su

The responses to step and pulse transients with reactants have been simulated for conventional step-transient conditions at atmospheric pressure and pulsing under vacuum using a temporal analysis of products (TAP) reactor, respectively. Propene oxidation over an oxide catalyst with the participation of lattice oxygen was chosen as a model reaction. The mechanism comprises adsorption of the reactan
