P>An alignment of upstream regions of anaerobically induced genes in Staphylococcus aureus revealed the presence of an inverted repeat, corresponding to Rex binding sites in Streptomyces coelicolor. Gel shift experiments of selected upstream regions demonstrated that the redox-sensing regulator Rex of S. aureus binds to this inverted repeat. The binding sequence - TTGTGAAW(4)TTCACAA - is highly co
ABSTRACT: BACKGROUND: Topical negative pressure (TNP), commonly used in wound therapy, has been shown to increase blood flow and stimulate angiogenesis in skeletal muscle. We have previously shown that a myocardial TNP of -50 mmHg significantly increases microvascular blood flow in the myocardium. When TPN is used in wound therapy (on skeletal and subcutaneous tissue) a zone of relative hypoperfus
Studies of ornaments as indicators of individual quality have hitherto focused on males, while studies of female ornaments have been almost absent. However, females within the same species may show large variation in both outer appearance and individual quality. We experimentally examined the effect of an immune challenge on the size of white fringes in the wing feathers produced one to two months
We have studied the biosynthesis of mucins in organ cultures of human colon using isopycnic density-gradient centrifugation following pulse labelling with [35S]sulphate and [3H]-D-glucosamine. A high-density [35S]sulphate labelled component, of larger size than MUC2 monomers, appeared in the tissue and also in the medium. It was not degraded by reduction, trypsin digestion, digestion with chondroi
Abstract in UndeterminedAims: To examine how left atrioventricular plane displacement ( AVPD), a widely used measure of left ventricular (LV) function, is related to presence and degree of aortic stenosis. Methods and results: Cardiac dimensions, LV filling, left AVPD, LV ejection fraction (LVEF), and valve function were assessed by echocardiography/Doppler in 182 patients with various cardiac dis
Recently, associations of several common genetic variants with height have been reported in different populations. We attempted to identify further variants associated with adult height in a self-contained population (the Sorbs in Eastern Germany) as discovery set. We performed a genome wide association study (GWAS) (similar to 390 000 genetic polymorphisms, Affymetrix gene arrays) on adult height
Perceived control is of significance in occupational therapy, as revealed in empirical research and suggested in practice models. This study investigated the relationship between perceived control and occupational performance in persons with long-term mental illness. The 177 participants were assessed regarding perceived control (locus of control and self-mastery) and occupational performance (act
Atopic eczema (AE) is a major risk factor for hand eczema. In Scandinavian population-based studies, the occurrence of AE in childhood has often been assessed by the question 'Have you had childhood eczema?' In the present study, this question was validated. A questionnaire was sent to 600 cases with AE and 600 controls without eczema or allergic disease, identified in school medical records from
Background Fibroblast growth factor (FGF23) is a protein that is produced by osteoblasts and osteocytes. Increased serum levels of FGF23 have been associated with increased risks of osteoporotic fractures and cardiovascular disease, particularly in participants with poor renal function. Serum iron (Fe) has been suggested as a regulator of FGF23 homeostasis. Objective To determine whether Fe and ir
Background: The total cost of bile duct injuries (BDIs) in an unselected national cohort of patients undergoing cholecystectomy are unknown. The aim was to evaluate costs associated with treatment of cholecystectomy-related BDIs and to calculate cost effectiveness of routine vs. on-demand intraoperative cholangiography (IOC). Methods: Data from Swedish patients suffering a BDI during a 5 year peri
INTRODUCTION: Not only repolarization, but also depolarization ECG indexes reflect the progression of ischemic injury. The aim was to assess the QRS duration and morphology dynamics during the prolonged coronary occlusion and their association with the myocardial area at risk (MaR) and final infarct size (IS).METHODS: In pigs, myocardial infarction was induced by inflation of an angioplasty balloo
There is once again an increased demand for interventions supporting small and medium sized enterprises (SMEs) because of the widely held believe that they provide most of the jobs. In order to answer the question whether pro SME policies are justified on factual grounds the International Labour Organization (ILO) and the German Agency for International Cooperation (GIZ) came out with a new study
We investigate the responsiveness of academic patenting to research and development (R&D) at the subject level at Swedish universities in panel data regressions. The general responsiveness to R&D is found to be higher than corresponding estimates in US studies, especially when we adopt instrumental variable techniques that address endogeneity in the R&D-to-patent relationship studied.
In acute coronary syndromes without ST-segment elevation (NSTE-ACS), identification of the culprit artery is, most often, not possible. In this case report, we elaborate on the likelihood of different culprit arteries in a patient with NSTE-ACS. While her symptoms were progressing, typical ECG findings of ischemia in the left coronary territories were diminishing. Instead, dynamic T-wave changes i
Aim To investigate the association of temperature on arrival to hospital after out-of-hospital-cardiac arrest (OHCA) with the primary outcome of mortality, in the targeted temperature management (TTM) trial. Methods The TTM trial randomized 939 patients to TTM at 33 or 36 °C for 24 h. Patients were categorized according to their recorded body temperature on arrival and also categorized to groups o
The biosynthesis of dermatan sulfate is a complex process that involves, inter alia, formation of L-iduronic acid residues by C5-epimerization of D-glucuronic acid residues already incorporated into the growing polymer. It has been shown previously that this reaction is promoted by the presence of the sulfate donor 3'-phosphoadenosine-5'-phosphosulfate. In the present investigation, the role of su
