Background:Hypoxia is an element of the tumour microenvironment that impacts upon numerous cellular factors linked to clinical aggressiveness in cancer. One such factor, Snail, a master regulator of the epithelial-mesenchymal transition (EMT), has been implicated in key tumour biological processes such as invasion and metastasis. In this study we set out to investigate regulation of EMT in hypoxia

Anaerobic bacteria dominate the human normal microbiota but strikingly little is known about these commensals. Finegoldia magna is a Gram-positive anaerobe found in the skin and at other non-sterile body surfaces, but it is also an opportunistic pathogen. This study describes a novel protein designated FAF (F. magnaAdhesion Factor) and expressed by more than ninety percent of F. magna isolates. Th

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

In this study we have elucidated the effects of allergen-specific antibodies on human DCs and T-cells. Monocyte-derived DCs from allergic patients were exposed to Phlp 5 alone or in complex with Phlp 5-specific human IgG1, IgG4 or IgE and further co-cultured with autologous memory CD4+ T-cells. We demonstrate that DCs treated with Phlp 5/IgE-complexes secrete higher levels of IL-1a, IL-6, VEGF and

Object oriented modeling naturally leads to implicitly defined dynamical systems or, as they are also called, differential algebraic equations (DAEs). Most existing DAE integrators require the equations defining the dynamical system to have a special structure. Progress on the development of a new integrator for general unstructured DAEs is presented. The new integrator is called UCP. Computationa

Introduction to a theme section on film and cultural policy in Scandinavia.

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)

We present an online system for real time recognition of actions involving objects working in online mode. The system merges two streams of information pro- cessing running in parallel. One is carried out by a hierarchical self-organizing map (SOM) system that recognizes the performed actions by analysing the spa- tial trajectories of the agent’s movements. It consists of two layers of SOMs and a

OBJECTIVES: We investigated whether menopausal vasomotor symptoms (VMS) are related to an adverse cardiovascular risk profile. Furthermore, we examined the association between estradiol levels and VMS, and whether an association between VMS and cardiovascular risk factors can be explained by estradiol levels. STUDY DESIGN: We used data from a Swedish population-based sample of 5857 women, aged 50-

The evidence for central stimulant (CS) treatment in ADHD is strong in some respects but not with respect to unselected clinical material and long-term effects over the life course cycle. The objective of this study was to explore differences in vocational, psychiatric, and social impairment, including crime and substance abuse, among adults with ADHD, treated or not, with CS drugs before age 18.

OBJECTIVE: Vascular inflammation is a key feature of both micro- and macrovascular complications in diabetes. Several lines of evidence have implicated the cytokine tumor necrosis factor (TNF) alpha as an important mediator of inflammation in diabetes. In the present study we evaluated the role of TNF alpha in streptozotocin (STZ)-induced diabetes on vascular inflammation in C57BL/6 wild-type and

To understand the origin of disease risk in adulthood, factors in all stages of life and on different contextual levels should be considered. Therefore, the aim of this study was to investigate the relevance of a person's area of residence over their life course with regard to four outcomes: all-cause mortality; ischemic heart disease mortality and morbidity; cancer mortality and morbidity; and re

The aim was to describe, from the newly registered nurses' perspective, specific events when using their pedagogical knowledge in their everyday clinical practice. The design was qualitative and the critical incident technique was used. Data was collected via interviews with ten newly registered nurses who graduated from the same University program 10 months earlier and are now employed at a unive
