Reduced plant height and culm robustness are quantitative characteristics important for assuring cereal crop yield and quality under adverse weather conditions. A very limited number of short-culm mutant alleles were introduced into commercial crop cultivars during the Green Revolution. We identified phenotypic traits, including sturdy culm, specific for deficiencies in brassinosteroid biosynthesi
Large increases in regional cerebral blood flow (rCBF) have been measured in patients with Parkinson's disease (PD) following the administration of L-DOPA, but the underlying mechanisms have remained unknown. In this study, we have used rats with unilateral 6-hydroxydopamine (6-OHDA) lesions as a model of PD in order to compare the patterns of rCBF and regional cerebral glucose utilisation (rCGU)
To determine risk factors associated with increased meniscal body extrusion on knee magnetic resonance (MR) images in subjects free of radiographic osteoarthritis.
Abstract in Undetermined This paper investigates the incidence of trellis termination on the performance of turbo codes and accounts for the performance degradation often experienced in the absence of trellis termination. Analytical upper bounds on the performance for the ensemble of turbo codes using different trellis termination strategies as well as performance results obtained by computer simu
INTRODUCTION: This investigation aimed to evaluate thrombotic risk factors in children, with special reference to autoantibodies against prothrombin and protein S. MATERIALS AND METHODS: We studied 57 consecutive Swedish children and adolescents referred with a radiologically confirmed acute thrombotic event. Clinical data were collected and a thrombophilia investigation was performed, including a
PURPOSE: Predictive strategies for the treatment efficacy of cetuximab are currently not available for head and neck cancer. We investigated the correlation between the expression of epidermal growth factor receptor (EGFR) ligands and EGFR expression, and the growth inhibitory activity of cetuximab in a panel of head and neck squamous cell carcinoma (HNSCC) cell lines. METHODS: The growth inhibiti
BACKGROUND: Clinical stroke trials with stem cell-based approaches aiming for trophic actions, modulation of inflammation and neuroprotection are ongoing. However, experimental studies also suggest that neuronal replacement by grafted neural stem cells (NSCs) and possibly by endogenous NSCs from the subventricular zone (SVZ) may restore function in the stroke-damaged striatum. To evaluate the pote
Mutations in the BRCA1 and BRCA2 genes significantly contribute to hereditary breast cancer and ovarian cancer, but the phenotypic effect from different mutations is insufficiently recognized. We used a western Danish clinic-based cohort of 299 BRCA families to study the female cancer risk in mutation carriers and their untested first-degree relatives. Founder mutations were characterized and the
The programmability of modern graphics processing units (GPUs) provide great flexibility for creating a wide range of advanced effects for interactive graphics. Developing such effects requires writing not only shader code to be executed by the GPU but also supporting code in the application where the effect is to be used. This support code creates dependencies between effects and the applications
During the last century, mankind has introduced electricity and during the very last decades, the microwaves of the modern communication society have spread a totally new entity--the radiofrequency fields--around the world. How does this affect biology on Earth? The mammalian brain is protected by the blood-brain barrier, which prevents harmful substances from reaching the brain tissue. There is e
Over the last few decades, extensive studies by several groups have introduced the concept of cell-derived secreted extracellular membrane vesicles as carriers of complex molecular information. Owing to their pleiotropic biological effects and involvement in a wide variety of biological processes, extracellular membrane vesicles have been implicated in physiological as well as pathological events,

The purpose of this article is to launch a new conceptual design tool in rehabilitation engineering,technology, and Disability Studies, useful both as guidance and help for people with disabilities inanalyzing their own functional aids, and as inspiration and meta-guidelines for designers. It is nondiscriminatingand classification-free and differs from a mere classification system like theInternat
Severe asthma is a heterogeneous syndrome. Classification of asthma into phenotypes and endotypes can improve understanding and treatment of the disease. Identification and utilization of biomarkers, particularly those linked to T2 inflammation, can help group patients into phenotypes, predict those who will respond to a specific therapy, and assess the response to treatment.
SUMO4 M55V, located in IDDM5, has been a focus for debate because of its association to type I diabetes (TIDM) in Asians but not in Caucasians. The current study aims to test the significance of M55V association to TIDM in a large cohort of Swedish Caucasians, and to test whether M55V is associated in those carrying human leukocyte antigen (HLA) class II molecules. A total of 673 TIDM patients and
A negative linear association between androgen receptor (AR) function and the CAG repeat numbers is generally assumed. However, in vivo data concerning the association between CAG number and androgenic effects have been conflicting. Since former in vitro studies mostly have been based on extreme CAG lengths and reporter-systems containing viral promoters, the objective of this study was to investi
Right ventricular heart rupture is a devastating complication associated with negative pressure wound therapy (NPWT) in cardiac surgery. The use of a rigid barrier has been suggested to offer protection against this lethal complication by preventing the heart from being drawn up and damaged by the sharp sternum bone edges. The aim of this study was to investigate the haemodynamic effects of placin
