Debattartikel gällande överbelastning på akutmottagningen.An article discussing the problems of overcrowding at the emergency department.

The normal flora furnishes the host with ecological barriers that prevent pathogen attack while maintaining tissue homeostasis. Urinary tract infections (UTIs) constitute a highly relevant model of microbial adaptation in which some patients infected with Escherichia coil develop acute pyelonephritis, while other patients with bacteriuria exhibit an asymptomatic carrier state similar to bacterial

Artikeln utgör en läsning och kritik av de 12 böcker som utgavs av Aschehougs förlag i samband med 100 års-jubileet av kvinnlig rösträtt i Norge. Författarna inkluderar Toril Moi, Marthe Ramm Frotun, Mariken Halle, Agnes Ravatn m fl.

Context: Robot-assisted laparoscopic radical prostatectomy (RALP) using the da Vinci Surgical System (Intuitive Surgical, Sunnyvale, CA, USA) is now in widespread use for the management of localised prostate cancer (PCa). Many reports of the safety and efficacy of this procedure have been published. However, there are few specific reports of the limitations and complications of RALP. Objective: Th

Effects of helix destabilization on lipid membrane interaction, liposome rupture, and bacterial killing was investigated for variants of the antimicrobial peptide GKE21 (GKEFKRIVQRIKDFLRNLVPR), an internal sequence of human cathelicidin LL-37, by ellipsometry, circular dichroism, fluorescence spectroscopy, and bacterial radial diffusion assay. GKE21 displayed moderate helix induction in buffer, wh

Background and purpose A considerable number of patients who undergo surgery for spinal stenosis have residual symptoms and inferior function and health-related quality of life after surgery. There have been few studies on factors that may predict outcome. We tried to find predictors of outcome in surgery for spinal stenosis using patient- and imaging-related factors. Patients and methods 109 pati

Background: Dystroglycan (Dg) is a transmembrane protein that is a part of the Dystrophin Glycoprotein Complex (DGC) which connects the extracellular matrix to the actin cytoskeleton. The C-terminal end of Dg contains a number of putative SH3, SH2 and WW domain binding sites. The most C-terminal PPXY motif has been established as a binding site for Dystrophin (Dys) WW-domain. However, our previous

Fresh water from Lake Svartsjon, Sweden, was collected and four fractions were prepared: (1) adsorption on DEAE, (2) flocculation with Ca2+, (3) co-precipitation with Fe hydrous oxide and (4) co-precipitation with Mn hydrous oxide. The plutonium level in the lake is 65 fg/l (222 mu Bq/l), measured by ICP-QMS and ICP-SFMS. Pronounced accumulation in fractions (1) (34%) and (2) (66%), combined with

Using diluted methane/air mixtures in internal combustion engines has a potential of reducing emissions and increasing efficiency. However, the ignition systems used today show difficulties igniting lean mixtures. For this purpose a new high frequency (HF) ignition system using pulse generators and a resonance circuit to achieve a controlled number of sparks during a controlled period of time has

BACKGROUND:: The use of league tables during the last decade has frequently been employed to assess quality in health care. However, few studies have attempted to assess quality by quantifying the variability across the organizational units or attempted to investigate whether the units are the correct context that really influences the outcome under study. OBJECTIVES:: To quantify the variation be

We report on the fabrication and characterization of amplitude and phase samples consisting of well defined Au or Al features formed on ultrathin silicon nitride membranes. The samples were manufactured using electron beam lithography, metallization and a lift-off technique, which allow precise lateral control and thickness of the metal features. The fabricated specimens were evaluated by conventi

We present two alternative methods for fabrication of nanoimprint lithography stamps in SiO2 with sub-20 nm features: (a) optimized electron beam lithography (EBL) and lift-off patterning of a 15-nm thick Cr mask, and (b) aerosol deposition of W particles in the 20-nm size range. In both cases, the pattern transfer into SiO2 was performed using reactive ion etching (RIE) with CHF3 as etch gas. In

Impingement and forced convection are preferable methods for cooling gas turbine components. However, influences of various design parameters like crossflow and surface enlargements (like ribs) are not well understood. Thus there is a request for reliable and cost effective computational prediction methods, due to the experimental difficulties. such methods could be based on the numerical solution

Among the approximately 7,000 cytogenetically abnormal childhood and adult B- and T-lineage acute lymphoblastic leukemias (ALL) published to date, numerous recurring chromosomal aberrations and abnormality patterns have been identified, and it has been clearly shown that the cytogenetic features often correlate closely with specific morphologic, immunophenotypic, and clinical parameters. Thus, kar

Background and purpose The introduction of Monte Carlo (MC) techniques for treatment planning and also for verification purposes will have considerable impact on the radiation therapy planning process. The aim of this work was to use a virtual accelerator to study the performance of a MC-based electron dose calculation algorithm, implemented in a commercial treatment planning system. Methods The

Signal transduction in hematopoietic cells is a highly specific process. The stimulation of B cell receptor following antigen binding triggers, as a first step, phosphorylation of the cytoplasmic immunoreceptor tyrosine-based activation motifs (ITAMs). Src family tyrosine kinases Blk, Fyn, Lck, and Lyn as well as spleen kinase, Syk, are activated to transmit the signal further. In this review the

Most human adults carry the Epstein-Barr virus (EBV) and develop immunological memory against the structural and the virus-encoded cellular proteins. The EBV nuclear antigen 6 (EBNA6) elicits cytotoxic T cell responses and it also maintains a persistent antibody response. The majority of sera from EBV-seropositive individuals reacts with a synthetic peptide, p63, comprising 21 amino acids of a rep
