Students compete in European Union Science Olympiad 2010

In April 2010, young students from 21 countries competed in EUSO - the European Union Science Olympiad. Each country sent two teams of three students to an experimental science competition. The first day, the teams helped an alien find water on Earth, and the second day, they solved a criminal case.

Down-Regulation of the Oncogene Cyclin D1 Increases Migratory Capacity in Breast Cancer and Is Linked to Unfavorable Prognostic Features.

The oncogene cyclin D1 is highly expressed in many breast cancers and, despite its proliferation-activating properties, it has been linked to a less malignant phenotype. To clarify this observation, we focused on two key components of malignant behavior, migration and proliferation, and observed that quiescent G0/G1 cells display an increased migratory capacity compared to cycling cells. We also f

Targeting CD44 Expressed on Neutrophils Inhibits Lung Damage in Abdominal Sepsis.

Neutrophil infiltration is an insidious feature in septic lung injury, although the specific adhesive mechanisms regulating pulmonary recruitment of neutrophils in polymicrobial sepsis remain elusive. The aim of this present study was to define the role of CD44 in sepsis-induced neutrophil infiltration and lung damage. Mice were treated with a monoclonal antibody against CD44 before cecal ligation

Activated Protein C-Protein C Inhibitor Complex, Activation Peptide of Carboxypeptidase B and C-Reactive Protein as Predictors of Severe Acute Pancreatitis.

Introduction: The concentration of carboxypeptidase B activation peptide (CAPAP) is proposed to be a predictor of severe acute pancreatitis. The activated protein C (APC)-protein C inhibitor (PCI; APC-PCI) complex in plasma could be useful in detecting the hypercoagulative condition in severe acute pancreatitis. Method: In this prospective study, mild (n = 50) and severe (n = 9) cases of acute pan

Diagnostics and treatment of the diabetic foot.

Every 30 s, a lower limb is amputated due to diabetes. Of all amputations in diabetic patients 85% are preceded by a foot ulcer which subsequently deteriorates to a severe infection or gangrene. There is a complexity of factors related to healing of foot ulcers including strategies for treatment of decreased perfusion, oedema, pain, infection, metabolic disturbances, malnutrition, non-weight beari

Automatic mimicry reactions as related to differences in emotional empathy

The hypotheses were based on conceiving of automatic mimicking as involved in emotio¬nal empathy. Mimicry reactions (EMG) in high- and low-empathy subjects were studied when subjects were exposed to pictures of angry or happy faces. The degree of corre¬sponden¬ce between subjects’ facial EMG reactions and their self-reported feelings was compared. The comparisons were made at different stimulus ex

Socioeconomic and occupational risk factors for venous thromboembolism in Sweden: A nationwide epidemiological study.

Our aims were to investigate possible associations between hospitalisation for venous thromboembolism (VTE) and socioeconomic and occupational factors. A nationwide database was constructed by linking Swedish census data to the Hospital Discharge Register (1990-2007). Hospital diagnoses of VTE were based on the International Classification of Diseases. Standardised incidence ratios were calculated

Food sources of fat and sex hormone receptor status of invasive breast tumors in women of the malmö diet and cancer cohort.

We examined associations between food intakes and incident breast cancer, defined by estrogen receptor (ER) and progesterone receptor (PR) status in the Malmö Diet and Cancer cohort (17,000 women aged 45-73 yr). The hazard ratios (HRs) of ER+PR+ (n = 270), ER+PR- (n = 87), and ER-PR- (n = 61) tumors and all cancer (n = 544) were estimated after 10 yr of follow-up. In multivariate analysis of ER+PR

Chain shuffling to modify properties of recombinant immunoglobulins.

Combinatorial libraries and selection of variants from such libraries have proven to be a successful approach for identifying molecules with novel or improved properties. The importance of antibody (Ab) molecules in basic and applied research, as well as the extensive knowledge of how they interact with their antigen (Ag) targets, have made them favorite targets for modification by this approach.

Not Afraid at All? Dominant and Alternative Interpretative Repertoires in Discourses of the Elderly on Fear of Crime

This article demonstrates how a dominant and an alternative interpretative repertoire are activated and negotiated within two focus group discussions conducted with elderly people around the issue of fear of crime: the active, competent actor and the potential victim. In contrast to quantitative generalist studies that tend to neglect the ambiguity and complexity of group membership and identifica

A Simple Procedure for Determining Order Quantities under a Fill Rate Constraint and Normally Distributed Lead-Time Demand

One of the most common practical inventory control problems is considered. A single-echelon inventory system is controlled by a continuous review (R,Q) policy. The lead-time demand is normally distributed. We wish to minimize holding and ordering costs under a fill rate constraint. Although, it is not especially complicated to derive the optimal solution, it is much more common in practice to use

Inter-rater Reliability and Between-days Repeatability of Eight Physical Performance Tests

Results of reliability studies on physical performance tests are often conflicting. The main purpose of this study was to analyse the inter-rater reliability and between-days repeatability of physical performance tests on a female working population. Twenty-two nursing aides/ assistant nurses were tested twice, with, on average, a 5-day interval. Seventeen of these were tested again, after an aver

Light-induced immobilization of biomolecules as an attractive alternative to micro-droplet dispensing-based arraying technologies

The present work shows how UV light-induced molecular immobilisation (LIMI) of biomolecules onto thiol reactive surfaces can be used to make biosensors, without the need for traditional microdispensing technologies. Using LIMI, arrays of biomolecules can be created with a high degree of reproducibility. This technology can be used to circumvent the need for often expensive nano/microdispensing tec
