Mammalian cells, including tumor cells, adapt to hypoxia via stabilization of two transcription factors - Hypoxia-inducible factor (HIF)-1alpha and HIF-2alpha. Among other consequences, hypoxia is a main driving force behind angiogenesis. The differentiation stage of tumor cells is recognized as an important clinical factor in several malignancies including neuroblastoma. Tumors with an immature

Scandinavian Journal of Psychology.Relations between results of the Stress Strategy Test (SST), a computerized test the first author developed partly involving the Stroop effect, and of an interview and an intelligence test used by the Swedish armed forces as

Mating systems and parental care are predicted to coevolve because the former dictates the cost-benefit ratio of the latter by affecting genetic relatedness between adults and offspring. Reptiles show only rudimentary forms of sociality and parental care and, hence, could provide important insights into the early stages of the evolution and maintenance of social systems. The skink genus Egernia ex

Between 1992 and 2008, 713 high hyperdiploid acute lymphoblastic leukemias in children aged 1-15 years were diagnosed and treated according to the Nordic Society for Pediatric Hematology and Oncology acute lymphoblastic leukemia 1992/2000 protocols. Twenty (2.8%) harbored t(1;19), t(9; 22), der(11q23), or t(12; 21). The median age of patients with "classic" high hyperdiploidy was lower than that o

Neutrophils interacting with a chemoattractant gradually become nonresponsive to further stimulation by the same agonist, a process known as desensitization. Receptor desensitization is a highly regulated process that involves different mechanisms depending on which receptor-ligand pair that is studied. Galectin-3, a member of a large family of beta-galactoside-binding lectins, has been suggested

A central question in Alzheimer's disease (AD) research is what role β-amyloid peptide (Aβ) plays in synaptic dysfunction. Synaptic activity increases Aβ secretion, potentially inhibiting synapses, but also decreases intraneuronal Aβ, protecting synapses. We now show that levels of secreted Aβ fall with time in culture in neurons of AD-transgenic mice, but not wild-type mice. Moreover, the ability

In Sweden, a large share of public services are organised, produced and delivered by municipalities, large and small, rich and poor. Contextual conditions (size and location) and economic conditions (efficiency and wealth) differ considerably among these service-providing organisations. The question raised in this paper is whether a municipality's economic situation is a direct consequence of the

Objective. To study lumbopelvic pain in women randomized to a regular exercise program during pregnancy in comparison to women receiving standard antenatal care. Design. A two-armed, two-center, randomized controlled trial. Setting. St Olavs Hospital, Trondheim University Hospital and Stavanger University Hospital. Population. A total of 855 pregnant women were randomized to intervention or contro

Objective: The concept of occupational balance is frequently used in occupational therapy but the fact that it has been defined and measured differently is a limitation. This article introduces the Occupational Balance Questionnaire (OBQ), which focuses on satisfaction with the amount and variation of occupations. It consists of 13 items measured on six-step ordinal scales. It has shown good conte

This inaugural lecture in the Royal Swedish Academy of Letters, History and Antiquities discusses the silence in Swedish press and in the Church of Sweden on National socialism, 1933-1939. This silence was neither common nor general, it was often concentrated to certain levels or matters. Silence could be compact, while the silent persons could speak on other levels, in other words, often in a the

We carried out a combined study of UV-VUV luminescence and resonant x-ray emission from BeO single crystals with incident photon energies in the vicinity of the Be 1s absorption edge. The x-ray emission spectra show that at the Be 1s photoabsorption edge the lattice relaxation processes in the excitation site take place already on the timescale of the radiative decay of the core excitation. Compar

This paper analyses the consequences, in Denmark between 1984 and 2006, of the implementation of the European EU Eighth Directive on the qualification of statutory auditors. Although the Eighth Directive envisaged one group of statutory auditors in each Member State, there were two groups of auditors in Denmark, and the implementation of the Directive triggered a long conflict between the two grou

Using a new database that matches patent applications by Swedish residents with demographic information from 1985 to 2007, we examine differences in inventive performance by individuals of foreign and domestic origins, in terms of quantity (probability of patenting, total number of patents per inventor) and quality (forward citations, probability of grant) of patents. We further compare adult and

Evidence is accumulating that one of the strongest predictors of retinopathy of prematurity (ROP), in addition to low gestational age, is poor weight gain during the first weeks of life. In infants born preterm, the retina is not fully vascularised. The more premature the child, the larger is the avascular area. In response to hypoxia, vascular endothelial growth factor (VEGF) is secreted. For app

We present a re-analysis of the Geneva-Copenhagen survey, which benefits from the infrared flux method to improve the accuracy of the derived stellar effective temperatures and uses the latter to build a consistent and improved metallicity scale. Metallicities are calibrated on high-resolution spectroscopy and checked against four open clusters and a moving group, showing excellent consistency. Th

Zeaxanthin is a carotenoid produced by plants and has been associated with protection of the photosynthetic machinery under light stress and, together with lutein, in protection of the central retina of the eye. Zeaxanthin levels in blood plasma have been negatively correlated to the development of AMD (age-related macular degeneration) (Gale et al, 2003). Under normal conditions, plants have a lo

Objective: To determine plasma apolipoprotein M ( apoM) levels and other lipid profiles in hepatocellular carcinoma ( HCC) patients compared to other chronic liver diseases and normal subjects. Materials and methods: 36 HCC, 68 chronic hepatitis, 29 liver cirrhosis patients and 64 normal controls were subjected in the present study. Serum lipids, lipoproteins, apolipoprotein AI ( apoAI) and apoB w

The available knowledge on the mechanisms of a bioprocess system is central to process analytical technology. In this respect, mechanistic modeling has gained renewed attention, since a mechanistic model can provide an excellent summary of available process knowledge. Such a model therefore incorporates process-relevant input (critical process variables)-output (product concentration and product q
