Associations between adolescent smoking habits and exercise, particularly participation in sports and lung function were studied. All students aged 13-19 yrs in Nord-Trondelag County, Norway, 1995-1997, were invited to join a cross-sectional study. Information on smoking habits and exercise was obtained by self-administered questionnaire. Spirometry was performed in accordance with American Thorac
Double minutes (dmin)-circular, extra-chromosomal amplifications of specific acentric DNA fragments-are relatively frequent in malignant disorders, particularly in solid tumors. In acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS), dmin are observed in similar to 1% of the cases. Most of them consist of an amplified segment from chromosome band 8q24, always including the MYC gene. B
Core-level photoelectron spectra, in excellent agreement with ab initio calculations, confirm that the stable wetting layer of water on Ru{0001} contains O-H and H2O in roughly 3:5 proportion, for OHx coverages between 0.25 and 0.7 ML, and T<170 K. Proton disorder explains why the wetting structure looks to low energy electron diffraction (LEED) to be an ordered p(root3xroot3)R30degrees adlayer, e
Malignant melanoma is an aggressive, heterogeneous disease where new biomarkers for diagnosis and clinical outcome are needed. We searched for chromosomal aberrations that characterize its pathogenesis using 47 different melanoma cell lines and tiling-resolution bacterial artificial chromosome-arrays for comparative genomic hybridization. Major melanoma genes, including BRAF, NRAS, CDKN2A, TP53, C
Aim: The objective of this study was to describe patients who experienced an out-of-hospital cardiac arrest (OHCA) by age group. Methods: All patients who suffered from an OHCA between 1990 and 2005 and are included in the Swedish Cardiac Arrest Registry (n = 40,503) were classified into the following age groups: neonates, younger than 1 year; young children, between 1 and 4 years; older children,
Objectives: To develop an automated tool for the analysis of electrocardiograms (ECG) with respect to changes that make the patient a candidate for reperfusion therapy. An additional aim was to assess the influence of the tool on the ECG classifications of three interns. Methods and Results: An artificial neural network was trained to interpret ECGs regarding changes making the patient a candi
BACKGROUND: The purpose of this study was to evaluate the effects of light propofol sedation on gastric emptying and orocecal transit time (OCT). METHODS: Ten healthy male volunteers were studied on 2 occasions separated by at least 1 week and were randomly allocated to receive either propofol sedation or i.v. saline as a control. During propofol sedation the volunteers were sedated to grade 2-3 o
Prostate-specific antigen (PSA) is a chymotrypsin-like serine protease exclusively produced by the prostate epithelium, and abundant in seminal fluid. In serum, PSA is predominantly complexed to a liver-derived serine protease inhibitor, alpha-1-antichymotrypsin (ACT). A higher proportion of serum PSA is complexed to ACT in prostate cancer than in benign prostate hyperplasia. Since the molecular b
Purpose. Patients with fibromyalgia (FM) and chronic widespread pain (CWP) find physical activity troublesome. The purpose was to develop a questionnaire to investigate the experience of physical activity in FM and CWP populations. Method. A questionnaire was developed from a qualitative study. After that, a total of 204 patients with FM or CWP completed the questionnaire. A factor analysis was co
OBJECTIVE: To determine 1. whether maternal fever during term labour is associated with acidaemia at birth and neonatal infection and 2. whether fetal tachycardia precedes maternal fever and is associated with neonatal infection. DESIGN: Retrospective matched-pair case-control study. SUBJECTS: Two hundred and forty-eight newborn infants whose mothers developed fever during term labour (cases) and
Carbonyl carotenoids are important constituents of the antenna complexes of marine organisms. These carotenoids possess an excited state with a charge-transfer character ( intramolecular charge transfer state, ICT), but many details of the carotenoid to chlorophyll energy transfer mechanisms are as yet poorly understood. Here, we employ femtosecond transient absorption spectroscopy to study energy
Objectives: Cardiovascular disease (CVD) is the leading cause of mortality worldwide. A high level of low-density lipoprotein cholesterol (LDL-C) is a major CVD risk factor. Guidelines recommend effective cholesterol management and set LDL-C goals, yet deficiencies exist in physician implementation of these recommendations and in patient uptake of the advice. However, little is known of patient pe
Starting from mature vegetable compost, four bacterial strains were selected using a lignin-rich medium. 16S ribosomal RNA identification of the isolates showed high score similarity with Pseudomonas spp. for three out of four isolates. Further characterization of growth on mixtures of six selected lignin model compounds (vanillin, vanillate, 4-hydroxybenzoate, p-coumarate, benzoate, and ferulate)
