Associations between in-hospital bed occupancy and unplanned 72-h revisits to the emergency department: a register study.

A possible downstream effect of high in-hospital bed occupancy is that patients in the emergency department (ED) who would benefit from in-hospital care are denied admission. The present study aimed at evaluating this hypothesis through investigating associations between in-hospital bed occupancy at the time of presentation in the ED and the probability for unplanned 72-hour (72-h) revisits to the

Characterization of the chronic myelomonocytic leukemia associated TEL-PDGF beta R fusion protein

The t(5;12) translocation, associated with chronic myelomonocytic leukemia, generates a novel gene encoding a protein, TEL-PDGF beta R, composed of the 154 amino-terminal amino acids of the transcription factor TEL and the transmembrane and intracellular part of the PDGF beta-receptor (PDGF beta R). TEL also occurs as a tumor-associated fusion partner for the tyrosine kinases c-ABL, JAK2 and TRK-C

Cardiovascular and cancer mortality in very elderly post-myocardial infarction patients receiving statin treatment.

OBJECTIVES: The purpose of this study was to determine whether statin treatment is effective and safe in very elderly (80 years and older) acute myocardial infarction (AMI) patients. BACKGROUND: Elderly individuals constitute an increasing percentage of patients admitted to hospitals for AMI. Despite that these patients have a higher mortality risk, the application of evidence-based medicine remai

Monitoring of volcanic sulphur dioxide emissions using differential absorption lidar (DIAL), differential optical absorption spectroscopy (DOAS), and correlation spectroscopy (COSPEC)

The total fluxes of sulphur dioxide from the Italian volcanoes Etna, Stromboli, and Vulcano were studied using optical remote sensing techniques in three shipborne field experiments (1992, 1994, and 1997). The main purpose of the experiments was to compare active (laser) techniques with passive monitoring. Differential absorption lidar (DIAL) measurements were implemented by placing the Swedish mo

Measuring attachment security directly: A suggested extension to the two-factor adult attachment construct

This study investigated a three-dimensional model of attachment based on the Relationship Questionnaire (Bartholomew & Horowitz, 1991) and the Relationship Scales Questionnaire (RSQ-R; Griffin & Bartholomew, 1994) in three different samples (n=254, n=129, n=168). Confirmatory factor analysis suggested a three-dimensional model to have better fit than a two dimensional one. The three factor

Interactions of histidine-rich glycoprotein with immunoglobulins and proteins of the complement system.

This study describes how the serum protein histidine-rich glycoprotein (HRG) affects the complement system. We show that HRG binds strongly to several complement proteins: C1q, factor H and C4b-binding protein and that it is found complexed with these proteins in human sera and synovial fluids of rheumatoid arthritis patients. HRG also binds C8 and to a lesser extent mannose-binding lectin, C4 and

Structure and Interactions of a Dimeric Variant of sHIP, a Novel Virulence Determinant of Streptococcus pyogenes.

Streptococcus pyogenes is one of the most significant bacterial pathogens in the human population mostly causing superficial and uncomplicated infections (pharyngitis and impetigo) but also invasive and life-threatening disease. We have previously identified a virulence determinant, protein sHIP, which is secreted at higher levels by an invasive compared to a non-invasive strain of S. pyogenes. Th

Subarachnoid Hemorrhage Induces Enhanced Expression of Thromboxane A(2) Receptors in Rat Cerebral Arteries.

Cerebral ischemia remains the key cause of morbidity and mortality after subarachnoid hemorrhage (SAH) with a pathogenesis that is still poorly understood. The aim of the present study was to examine the involvement of thromboxane A(2) receptors (TP) in the patophysiology of cerebral ischemia after SAH in cerebral arteries. SAH was induced in rats by injecting 250 microl blood into the prechiasmat

Words that second language learners are likely to hear, read, and use

In the present study, we explore whether multiple data sources may be more effective than single sources at predicting the words that language learners are likely to know. Second language researchers have hypothesized that there is a relationship between word frequency and the likelihood that words will be encountered or used by second language learners, but it is not yet clear how this relationsh

Self-efficacy, physical activity and health-related quality of life in middle-aged meniscectomy patients and controls.

Our purpose was to examine self-efficacy of knee function, physical activity (PA) and health-related quality of life (HRQoL) in post-meniscectomy patients and controls as well as to explore the impact of gender and the association between outcomes. Ninety-nine post-meniscectomy patients (27% women), mean age 44.5 years, mean (range) of follow-up time 3 (1-5) years, and 94 controls (34% women), mea

The Antibacterial Chemokine MIG/CXCL9 Is Constitutively Expressed in Epithelial Cells of the Male Urogenital Tract and Is Present in Seminal Plasma.

ABSTRACT The integrity of the urogenital tract against potentially invasive pathogens is important for the health of the individual, fertilization, and continuance of species. Antibiotic peptides with broad antimicrobial activity, among them chemokines, are part of the innate immune system. We investigated the presence of the antibacterial interferon (IFN)-dependent CXC chemokines, MIG/CXCL9, IP-1

Highly sensitive polymer-based cantilever-sensors for DNA detection

We present a technology for the fabrication of cantilever arrays aimed to develop an integrated biosensor microsystem. The fabrication process is based on spin coating of the photosensitive polymer and near-ultraviolet exposure. Arrays of up to 33 microcantilevers are fabricated in the novel polymer material SU-8. The low Young's modulus of the polymer, 40 times lower than that of silicon, enables

Large Eddy Simulation of Turbulent Swirling Flows in Combustor Related Geometries

Popular Abstract in English The concern about pollutant emissions from combustion devices has stimulated the development of modern combustion devices. As one of the major power generation machines, modern gas turbine engine has been designed to run at fuel-lean and premixed mode of combustion in which the combustion temperature is moderate so that NOx emission is low. Combustion in premixed mode rThis thesis deals with the physics of turbulent swirling flows. Large eddy simulation (LES) method is used to investigate the vortex breakdown process, the precessing vortex core (PVC), and the effect of swirl number and flow field configuration on swirling flows. The study is based on an open source CFD code, \textit{OpenFoam}. Turbulent swirling flows are widely used in combustion devices such a

Predictors of response to anti-TNF therapy according to ACR and EULAR criteria in patients with established RA: results from the South Swedish Arthritis Treatment Group Register.

OBJECTIVE: To identify factors predicting response to first TNF blocking treatment course in patients with established RA with a special focus on gender differences. METHODS: Patients with active RA initiating their first treatment course of TNF-blocking therapy were enrolled. The study period was March 1999 through September 2006. The prospective protocol included information on demographics, cli

Lysine-Specific Demethylase 1 Is Strongly Expressed in Poorly Differentiated Neuroblastoma: Implications for Therapy.

Aberrant epigenetic changes in DNA methylation and histone acetylation are hallmarks of most cancers, whereas histone methylation was previously considered to be irreversible and less versatile. Recently, several histone demethylases were identified catalyzing the removal of methyl groups from histone H3 lysine residues and thereby influencing gene expression. Neuroblastomas continue to remain a c
