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
The efficacy and safety of an advanced category recombinant antihaemophilic factor produced by a plasma- and albumin-free method (rAHF-PFM) was studied in 111 previously treated subjects with haemophilia A. The study comprised a randomized, double-blinded, crossover pharmacokinetic comparison of rAHF-PFM and RECOMBINATE rAHF (R-FVIII); prophylaxis (three to four times per week with 25-40 IU kg(-1)
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
The human B1 bradykinin receptor is an inducible and constitutively active G protein-coupled receptor that is involved in the inflammatory and pain responses to injury. Here, we investigated the role of B1 receptor homo-oligomerization in cell surface receptor expression. B1 receptors tagged with either the FLAG or hemagglutinin epitope were monitored immunologically and by radio-ligand binding, b
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
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
Background: Intrauterine growth retardation (IUGR) resulting in infants born small for gestational age is a known risk factor for neurologic deficits and may predispose to poor cognitive development later in life. We recently found an association between IUGR and a reduced neuroretinal rim area at 18 years of age. We evaluated the possible association between IUGR and visual function. Subjects and
