Evaluation of accuracy and applicability of protein models: retrospective analysis of biological and biomedical predictions.

In order to study protein function and activity structural data is required. Since experimental structures are available for just a small fraction of all known protein sequences, computational methods such as protein modelling can provide useful information. Over the last few decades we have predicted, with homology modelling methods, the structures for numerous proteins. In this study we assess t

Effect of charge on microvascular permeability in early experimental sepsis in the rat.

A key feature of sepsis is hypovolemia due to increased microvascular permeability. It has been suggested that the negative charge of albumin and of the endothelial glycocalyx is important for maintenance of the normally low permeability for albumin. Here we tested the hypothesis that charge effects contribute to the increased permeability in sepsis. Transcapillary escape rate (TER) and initial di

Lidar Measurements of Atmospheric Mercury

Mercury is the only atmospheric pollutant that is present in the atmosphere in atomic form. The optical resonance line at 254 nm can be used for absorption measurements using different optical remote sensing techniques. Range-resolved Hg mapping can be performed using the differential absorption lidar (DIAL) technique. We have used the lidar technique both for mapping of industrial plumes and for

Effect of stunning conditions on occurence of PSE defects in hams of rn+/RN- pigs

Pigs of the same genetic type at the RN and HAL loci, i.e. rn(+) RN-/NN were reared in similar conditions of feeding and housing. They were slaughtered in two abattoirs (referred to as A1 and A2) using a mixture of air (30%) and CO2 (70%), at a rate of 300 pigs per hour per slaughterline. One hundred and thirty-two pigs from I I farms were slaughtered in A I using a corusinga restrainer and 127 pi

Musikelever på gymnasiets estetiska program : En studie av elevernas bakgrund, studiegång och motivation

Tidigare forskning om motivation vid lärande har tenderat att fokusera på attributioner (de tolkningar elever och andra gör av orsaker till framgångar och misslyckanden) självuppfattning, målorientering och elevers autonomi. Denna avhandling syftar dels till att beskriva bakgrunden och skolgången för de elever som går på gymnasiets estetiska programs musikgren, dels till att mäta den motivation deIn previous studies research on motivation in education has tended to be focused on attribution (perceived causes of success and failure), self perception, goal orientation and autonomy. This thesis aims to describe the background and schooling of music students and to measure their motivation for music education. Motivation is viewed as a cognitive process, which influences learning through achie

Time to diagnosis, of melanoma: same trend in different continents

Background: Patients and physicians both play an important role in the diagnosis of malignant melanoma. Objective: The purpose of this study was to assess important factors of delay in diagnosis at different centers and on three continents. Methods: Between October 2001 and October 2002, patients with histologically confirmed invasive melanoma were included in the study and given an established qu

The influence of vigilance on intraguild predation

Theoretical work on intraguild predation suggests that if a top predator and an intermediate predator share prey, the system will be stable only if the intermediate predator is better at exploiting the prey, and the top predator gains significantly from consuming the intermediate predator. In mammalian carnivore systems, however, there are examples of top predator species that attack intermediate

Distinct gene expression profiling in chronic lymphocytic leukemia with 11q23 deletion

Chronic lymphocytic leukemia (CLL) is a heterogeneous disease with regard to its clinical course. The limitations of the methods currently available for prognostic assessment in CLL do not allow accurate prediction of the risk of disease progression in Individual patients. The recently developed cDNA array technique provides a unique opportunity to study gene expression in various malignancies. To

A method for analysing the traffic process in a safety perspective

The aim of this study is to extend the traffic safety assessment concept to also include normal road user behaviour, thus not only exceptional behaviours such as accidents and serious conflicts. The goal is to provide a framework for a more thorough description and analysis of safety related road user behaviour in order to better understand the traffic safety processes. The traffic safety process

Numerical simulations using an improved calculational scheme for ion charge state distribution and ion temperature evolution in an EBIT

A calculation scheme with significant modifications and improvements for determining the ionization balance and the ion temperature evolution in an electron beam ion trap (EBIT) is presented. The scheme is applied to thorium, tantalum and oxygen ions using a specific set of EBIT operating parameters. The results of the calculation are compared to experiment and previous calculations. Rates for the

Counseling Hypertensive patients: an observational study of 21 public health nurses

This study observed the public health nurse's and the patient's activity level during blood pressure measurement and the kind of nonpharmacological treatment that was given. Using the Nurse Practitioner Rating Form, three structured observations were made of 21 public health nurses at their offices at health care centers. The nurses were randomly selected from 22 health care centers in Southern Sw

Comparison of three commercially available peptide-based immunoglobulin G (IgG) and IgA assays to microimmunofluorescence assay for detection of Chlamydia trachomatis antibodies

Three commercially available, peptide-based enzyme-linked immunosorbent assay (ELISA) systems (Chlamydia trachomatis IgG and IgA EIA [CT-EIA; Labsystems OY, Helsinki, Finland], SeroCT IgG and IgA [SeroCT; Savyon Diagnostics Ltd., Ashdod, Israel], and Chlamydia trachomatis IgG and IgA pELISA [CT pELISA; Medac, Wedel, Germany]) were evaluated for the detection of serum immunoglobulin G (IgG) and IgA

Long-term beneficial effects of glipizide treatment on glucose tolerance in subjects with impaired glucose tolerance

To assess the efficacy and long-term effects of glipizide treatment on glucose and insulin metabolism in individuals with impaired glucose tolerance (IGT). Thirty-seven first-degree relatives of patients with type 2 diabetes fulfilling WHO criteria for IGT were randomized to treatment with either glipizide 2.5 mg once daily or matching placebo for 6 months. A 75 g, 2-h oral (OGTT) and 60 min intra

Critical loads - is there a need for a new concept?

The concept of critical loads has been an important and successful tool for the development of control strategies for transboundary air pollution in Europe. The use of the concept has led us to a situation where very few areas in Europe will have an exceedance of critical loads for acidification in 2010, indicating that the benefits of further control acidifying substances will be less useful. The
