Positioning of a Polymorphic Quantitative Trait Nucleotide in the Ncf1 Gene Controlling Oxidative Burst Response and Arthritis Severity in Rats.

The Ncf1 gene, encoding the P47PHOX protein that regulates production of reactive oxygen species (ROS) by the phagocyte NADPH oxidase complex, is associated with autoimmunity and arthritis severity in rats. We have now identified that the single nucleotide polymorphism (SNP) resulting in an M153T amino acid substitution mediates arthritis resistance and thus explains the molecular polymorphism und

Comparison of (GTG)(5)-oligonucleotide and ribosomal intergenic transcribed spacer (ITS)-PCR for molecular typing of Klebsiella isolates

Molecular typing of Klebsiella species has become important for monitoring dissemination of beta-lactamase-producers in hospital environments. The present study was designed to evaluate poly-trinucleotide (GTG)(5)- and rDNA intergenic transcribed spacer (ITS)-PCR fingerprint analysis for typing of Klebsiella pneumoniae and Klebsiella oxytoca isolates. Multiple displacement amplified DNA derived fr

Enhancement of glucagon secretion in mouse and human pancreatic alpha cells by protein kinase C (PKC) involves intracellular trafficking of PKCalpha and PKCdelta.

AIMS/HYPOTHESIS: Protein kinase C (PKC) regulates exocytosis in various secretory cells. Here we studied intracellular translocation of the PKC isoenzymes PKCalpha and PKCdelta, and investigated how activation of PKC influences glucagon secretion in mouse and human pancreatic alpha cells. METHODS: Glucagon release from intact islets was measured in static incubations, and the amounts released were

Selection Bias in Choice of Words: Evaluations of ”I” and ”We” Differ between Contexts, but ”They” are Always Worse

In everyday life, people use language to communicate evaluative messages about social categories. We examine a selection bias in language across two social dimensions not previously integrated; a self-inclusive/self-exclusive dimension and an individual/collective dimension. We used pronouns as markers for social categories (I, We, He/she and They), and developed a new measure, the Evaluative Sent

High intakes of protein and processed meat associate with increased incidence of type 2 diabetes.

Diets high in protein have shown positive effects on short-term weight reduction and glycaemic control. However, the understanding of how dietary macronutrient composition relates to long-term risk of type 2 diabetes is limited. The aim of the present study was to examine intakes of macronutrients, fibre and protein sources in relation to incident type 2 diabetes. In total, 27 140 individuals, age

Carotenoid and melanin-based ornaments signal similar aspects of male quality in two populations of the common yellowthroat

P>1. Female preferences for particular male ornaments may shift between populations as a consequence of ecological differences that change the reliability and detectability of the ornament, but few studies have examined how ornaments function in different populations. 2. We examined the signalling function of male plumage ornaments in a warbler, the common yellowthroat (Geothlypis trichas), breedi

Neutron Time-of-Flight Quantification of Water Desorption Isotherms of Montmorillonite

The multiple energy states of water held by surfaces of a clay mineral can be effectively probed with time-of-flight and fixed elastic window neutron scattering. We used these techniques to quantitatively differentiate water types, including rotational and translational diffusions, in Ca- and Na-montmorillonite (SAz-1) and charge-reduced preparations equilibrated at RH = 33% and 55%, whose gravime

Trapping of human hemoglobin by haptoglobin: Molecular mechanisms and clinical applications.

Significance: Haptoglobin (Hp) is an abundant plasma protein controlling the fate of hemoglobin (Hb) released from red blood cells after intravascular hemolysis. The complex formed between Hp and Hb is extraordinary strong, and once formed, this protein-protein association can be considered irreversible. Recent advances: A model of the Hp-Hb complex has been generated and the first steps towards u

Why have microsaccades become larger? Investigating eye deformations and detection algorithms

Abstract in UndeterminedThe reported size of microsaccades is considerably larger today compared to the initial era of microsaccade studies during the 1950s and 1960s. We investigate whether this increase in size is related to the fact that the eye-trackers of today measure different ocular structures than the older techniques, and that the movements of these structures may differ during a microsa

A Case Study Evaluation of the Guideline-Supported QUPER Model for Elicitation of Quality Requirements

[Context & motivation] For market-driven software product developing organizations operating on a competitive open market, it is important to plan the product’s releases so that they can reach the market as early as possible with a competitive level of quality compared to its competitors' products. Hence, quality requirements can be seen as a key competitive advantage. The QUPER model was deve

Tuning the performance of an artificial protein motor

The Tumbleweed (TW) is a concept for an artificial, tri-pedal, protein-based motor designed to move unidirectionally along a linear track by a diffusive tumbling motion. Artificial motors offer the unique opportunity to explore how motor performance depends on design details in a way that is open to experimental investigation. Prior studies have shown that TW's ability to complete many successive

Differential activity of c-KIT splice forms is controlled by extracellular peptide insert length.

Understanding receptor activation is important for disease intervention. Activation of the receptor tyrosine kinase c-KIT is involved in numerous diseases including melanoma, mastocytosis, multiple myeloma and gastrointestinal stromal tumors. To better understand the regulation of activation, we studied the two c-KIT isoforms, c-KIT(-) and c-KIT(+) which differ by a tetrapeptide insert GNNK, locat

Psychometric properties of a Swedish version of the Pearlin Mastery Scale in people with mental illness and healthy people.

Background: Mastery refers to the degree to which people perceive that they can control factors that influence their life situation, and has been found important for people's quality of life and well-being. It is thus essential to be able to measure mastery in a valid and reliable way. Aim: This study aimed at using the Rasch measurement model to investigate the psychometric properties of a Swed

Prediction of Significant Prostate Cancer Diagnosed 20 to 30 Years Later With a Single Measure of Prostate-Specific Antigen at or Before Age 50

BACKGROUND: We previously reported that a single prostate-specific antigen (PSA) measured at ages 44-50 was highly predictive of subsequent prostate cancer diagnosis in an unscreened population. Here we report an additional 7 years of follow-up. This provides replication using an independent data set and allows estimates of the association between early PSA and subsequent advanced cancer (clinical

‘And People's Concerns Were Genuine: Why Didn't We Listen More?’: Nationalism, Multiculturalism and Recognition in Europe

The aim of this article is to draw attention to the dangerous, indeed poisonous, nature of the current debates on immigration and multiculturalism in today’s ‘omniphobic’ Europe, plagued not only by a severe economic crisis, but also a more general normative crisis, a ‘crisis of values’ so to speak, which has been consistently overlooked or manipulated by politicians and academics alike, or reduce

"I'm Dr Jekyll and Mr Hyde": Are GPs' antibiotic prescribing patterns contextually dependent? A qualitative focus group study.

Abstract Objective. To explore factors and circumstances contributing to prudent antibiotic prescribing for respiratory tract infections in primary care. Design. Two focus groups representing rural and urban areas. A semi-structured interview guide with open-ended questions and an editing analysis style was used. They were examined to identify meaning units that were sorted into categories in an i

EUCAARI ion spectrometer measurements at 12 European sites - analysis of new particle formation events

We present comprehensive results on continuous atmospheric cluster and particle measurements in the size range similar to 1-42 nm within the European Integrated project on Aerosol Cloud Climate and Air Quality interactions (EUCAARI) project. We focused on characterizing the spatial and temporal variation of new particle formation events and relevant particle formation parameters across Europe. Dif
