In this paper, we report the results of a systematic study of the scaling effects of Young's modulus of nanowires of body-centered cubic iron. The investigation is performed by employing molecular statics tensile simulations. Two different crystallographic orientations are studied. The simulations show that there is a size dependence in Young's modulus, where the different crystallographic orienta

This article focuses on the cultural and political landscape of the Danish islands of Lolland and Falster in the Middle Ages. The close economic and dynastic relationships between medieval Denmark and the Slavic area south of the Baltic Sea, as well as Slavic settlement on the islands,contributed to the emergence of complex realities and attitudes, as well as a particular ‘inbetweenness’of the isl

BACKGROUND: An open access technique might reduce severe vascular and visceral injuries. An open access technique through the umbilical cicatrix tube has been developed as a routine method with the goal to be easy, safe and used by all surgeons in patients without a previous midline incision. AIM: To evaluate the open technique in a prospective study in 100 consecutive laparoscopic operations rega

Various transport phenomena in conjunction with chemical reactions are strongly affected by reformer configurations and the properties of the involved porous catalyst layers. The considered composite duct is relevant for a methane steam reformer and consists of a porous layer for the catalytic chemical reactions, the fuel gas flow duct and the solid plate. In this paper, a fully three-dimensional

Antibodies directed towards non-neutralizing epitopes on the factor VIII protein (FVIII) may be detected in patients with haemophilia A. We evaluated the prevalence of non-neutralizing antibodies, in 201 inhibitor-negative brother pairs with severe haemophilia A, enrolled in the Malmö International Brother Study and the Haemophilia Inhibitor Genetics Study. To evaluate binding specificity of the a

The pathogenesis of primary dysmenorrhea is still poorly understood. The objective of the present investigation was to study differences in plasma concentrations of reproductive hormones in women with primary dysmenorrhea vs. healthy controls. In a prospective, parallel-group study we determined the plasma concentrations of oxytocin, vasopressin, follicle-stimulating hormone (FSH), luteinizing hor

The first meeting of international specialists in the field of von Willebrand disease (VWD) was held in the Åland islands in 1998 where Erik von Willebrand had first observed a bleeding disorder in some members of a family from Föglö and a summary of the meeting was published in 1999. The second meeting was held in 2010 and a report of the meeting was published in 2012. Topics covered included pro

Phthalic anhydride (PA) is a reactive low molecular weight compound used in the chemical industry. The exposure of PA may lead to work-related airway diseases such as rhinitis, chronic bronchitis, and asthma. The exposure gives rise to an increase in hapten-specific IgG antibodies in workers but with a low presence of specific IgE antibodies. In this study, the binding of PA to human hemoglobin (H

BACKGROUND: Pregnancy-related venous thromboembolism (VTE) is a major cause of maternal morbidity and mortality. A new risk assessment model for VTE in relation to pregnancy has been introduced in Sweden. We wished to determine the proportion of preventable VTE cases if the model had been in use and make a brief cost-benefit analysis. METHODS: A hospital-based retrospective case-control study of a

The aim of this study was to improve the accuracy and precision of perfusion fraction and blood velocity dispersion estimates in intravoxel incoherent motion (IVIM) imaging, using joint analysis of flow-compensated and non-flow-compensated motion-encoded MRI data. A double diffusion encoding sequence capable of switching between flow-compensated and non-flow-compensated encoding modes was implemen

In this issue of Cell Stem Cell, Ma et al. (2012) report a differentiation protocol for generating striatal projection neurons from human embryonic stem cells with high efficiency. The cells survive transplantation, reconnect striatal circuitry, and restore motor function in a mouse model of striatal neurodegeneration that mimics the central pathohology of Huntington's disease.

BACKGROUND: Hyponatremia is the most common electrolyte abnormality and it is associated with increased morbidity and mortality. The aim of the study was to investigate the underlying causes and management of hyponatremia in an unselected population presenting with hyponatremia to the emergency department. METHODS: A descriptive, retrospective hospital record study was performed. A database search

Nerve injuries extend from simple nerve compression lesions to complete nerve injuries and severe lacerations of the nerve trunks. A specific problem is brachial plexus injuries where nerve roots can be ruptured, or even avulsed from the spinal cord, by traction. An early and correct diagnosis of a nerve injury is important. A thorough knowledge of the anatomy of the peripheral nerve trunk as well
