Concentration variability of potent allergens of p-tert-Butylphenol-formaldehyde resin (PTBP-FR) in patch test preparations and commercially available PTBP-FR.

Background: p-tert-Butylphenol-formaldehyde resin (PTBP-FR) is a common component of glues used in the manufacturing of many plastic, electronic, rubber, wood, and leather products. Two main allergens of PTBP-FR have been described. Objectives: The objective of this study is to determine the concentrations of the two main allergens of PTBP-FR in diagnostic patch testing preparations and PTBP-FR av

Tracking differentiating neural progenitors in pluripotent cultures using microRNA-regulated lentiviral vectors.

In this study, we have used a microRNA-regulated lentiviral reporter system to visualize and segregate differentiating neuronal cells in pluripotent cultures. Efficient suppression of transgene expression, specifically in undifferentiated pluripotent cells, was achieved by using a lentiviral vector expressing a fluorescent reporter gene regulated by microRNA-292. Using this strategy, it was possib

Apoptosis-inducing factor mediates dopaminergic cell death in response to lps-induced inflammatory stimulus Evidence in Parkinson's disease patients.

We show that intranigral lipopolysaccharide (LPS) injection, which provokes specific degeneration of DA neurons, induced caspase-3 activation in the rat ventral mesencephalon, which was mostly associated with glial cells. In contrast, nigral DA neurons exhibited AIF nuclear translocation in response to LPS. A significant decrease of the Bcl-2/Bax ratio in nigral tissue after LPS injection was obse

The Impact of Meal Attributes and Nudging on Healthy Meal Consumption — Evidence from a Lunch Restaurant Field Experiment

We use a field experiment in a lunch restaurant to analyze how meal attributes and a “nudge” impact healthy labeled meal consumption. The nudge consists of increasing the salience of healthy labeled meals by placing them at the top of the menu. We find that certain meal attributes (e.g. poultry and red meat) greatly increase both sales and the market share of the healthy labeled meal. We conclude

Different molecular behavior of CD40 mutants causing hyper-IgM syndrome.

CD40/CD40 ligand (CD40L) cross-talk plays a key role in B-cell terminal maturation in the germinal centers. Genetic defects affecting CD40 cause a rare form of hyper-immunoglobulin M (IgM) syndrome, a disorder characterized by low or absent serum IgG and IgA, associated with recurrent infections. We previously reported on a few patients with homozygous CD40 mutations resulting in lack or severe re

Exogenous Glutamate Modulates Porcine Retinal Development in vitro.

Embryogenesis of the retina is a complex event orchestrated by a multitude of physical and biochemical signals. To study the impact of intrinsic developmental cues, the retinal tissue can be isolated in culture which also enables modulation of normal development for other purposes, i.e. transplantation of specific neuronal cell types. In the present experiment, cell type development of immature po

Moraxella catarrhalis: from interactions with the host immune system to vaccine development.

Moraxella catarrhalis is a human-restricted commensal that over the last two decades has developed into an emerging respiratory tract pathogen. The bacterial species is equipped with various adhesins to facilitate its colonization. Successful evasion of the human immune system is a prerequisite for Moraxella infection. This strategy involves induction of an excessive proinflammatory response, inte

Homozygosity for the EPHX2 K55R polymorphism increases the long-term risk of ischemic stroke in men: a study in Swedes.

OBJECTIVES: The soluble epoxide hydrolase (gene name EPHX2) is responsible for metabolism of 8,9 11,12 and 14,15-epoxyeicosatrienoic acids, vasodilator and anti-inflammatory substances. There are several functional polymorphisms in the EPHX2 gene: two of them, the K55R and R287Q, showing an altered metabolic activity in vitro, were associated with coronary heart disease and ischemic stroke in prev

Unique splicing pattern of the TCF7L2 gene in human pancreatic islets.

AIMS/HYPOTHESIS: Intronic variation in the TCF7L2 gene exhibits the strongest association to type 2 diabetes observed to date, but the mechanism whereby this genetic variation translates into altered biological function is largely unknown. A possible explanation is a genotype-dependent difference in the complex splicing pattern; however, this has not previously been characterised in pancreatic or

Breast tomosynthesis and digital mammography: a comparison of breast cancer visibility and BIRADS classification in a population of cancers with subtle mammographic findings.

The main purpose was to compare breast cancer visibility in one-view breast tomosynthesis (BT) to cancer visibility in one- or two-view digital mammography (DM). Thirty-six patients were selected on the basis of subtle signs of breast cancer on DM. One-view BT was performed with the same compression angle as the DM image in which the finding was least/not visible. On BT, 25 projections images were

Development and Psychometric Evaluation of the Pain Impact Inventory.

Abstract Objectives: The aim of this study was to develop and psychometrically evaluate an instrument for measuring the impact of chronic pain on daily life. Methods: The study comprised 384 respondents (aged between 18-102 years) who reported chronic pain. The instrument "Pain Impact Inventory" (PII) was evaluated in terms of face, content, construct and criterion validity, as well as two reliabi

Stimulation of oestrogen receptor-expressing endothelial cells with oestrogen reduces proliferation of cocultured vascular smooth muscle cells.

1. Oestrogen reduces vascular smooth muscle cell proliferation in mouse vascular injury models. Data on the antiproliferative effect of oestrogen in cultured vascular smooth muscle cells (VSMC) are less conclusive than those obtained in whole animal studies. 2. In the present study, we investigated the hypothesis that oestrogen-induced attenuation of VSMC proliferation is facilitated by the presen

Prevalence and incidence of HIV-1 and HIV-2 before, during and after a civil war in an occupational cohort in Guinea-Bissau, West Africa.

OBJECTIVES:: To study prevalence and incidence of HIV-1 and HIV-2 between 1990 and 2007 and to examine impact of the civil war in 1998-1999. We also wanted to investigate possible interaction between HIV-1 and HIV-2. DESIGN:: Open prospective cohort study of 4592 police officers in Guinea-Bissau, West Africa. METHODS:: Analysis of HIV-1 and HIV-2 prevalence and incidence divided in 2-3 years time

Sternocutaneous fistulas after cardiac surgery: incidence and late outcome during a ten-year follow-up.

BACKGROUND: Sternocutaneous fistulas (SCFs) after cardiac surgery represent a complex surgical problem involving multiple hospital admissions, prolonged antibiotic treatment, and repeated debridements. Our objective was to identify the incidence of and risk factors for SCF, and to evaluate long-term survival. METHODS: A total of 12,297 patients underwent sternotomy for cardiac surgery between Janu

Phenotype associated with mutation in the recently identified autosomal dominant retinitis pigmentosa KLHL7 gene.

OBJECTIVE: To characterize the clinical phenotype, with an emphasis on electrophysiologic findings, in a family with autosomal dominant retinitis pigmentosa caused by mutation in the recently identified KLHL7 gene. METHODS: Eleven patients from a single family were selected from the Swedish retinitis pigmentosa register. Four patients had been examined 13 to 17 years earlier and underwent further

An epidemiological study of collagenous colitis in southern Sweden from 2001-2010.

AIM: To estimate the incidence of collagenous colitis (CC) in southern Sweden during 2001-2010. METHODS: Cases were identified by searching for CC in the diagnostic registers at the Pathology Departments in the county of Skåne. The catchment area comprised the south-west part of the county (394 307 inhabitants in 2010) and is a mixed urban and rural type with limited migration. CC patients that h
