Cytokines play a major role in lymphoid development. Defects of the common gamma chain (gamma (c)) or of the JAK3 protein in humans have been shown to result in a severe combined immune deficiency (SCID), with a profound defect in T and natural killer (NK)-cell development, whereas B-cell generation is apparently unaffected (T-B+NK- SCID). While extensive molecular and biochemical analysis of thes

OBJECTIVE: This study analyses the correlation between the Swedish underprivileged area score and sales of tranquillizers, hypnotics/sedatives, neuroleptics and antidepressants, and the correlation between these sales and mortality and suicide rates, with the aim of using sales data to identify areas with poor socioeconomic conditions. SETTING: Southern Sweden, 33 municipalities in Skane, 1987 and

Plasma homocysteine concentrations in a group of 80-year-old persons were related to symptoms and signs. Plasma homocysteine concentrations higher than 15 mumol/l were associated with lower total life satisfaction (P<0.01), mood (P<0.05), zest for life (P<0.05), lower scores for reasoning (P<0.05), spatial ability (P<0.05), memory recognition (P<0.05), and subjective health (P<0.01). In an instrum

Background. Some autoimmune and chronic inflammatory disorders are associated with increased risks of non-Hodgkin lymphoma (NHL). Because different NHL subtypes develop at different stages of lymphocyte differentiation, associations of autoimmune and inflammatory disorders with specific NHL subtypes could lead to a better understanding of lymphomagenic mechanisms. Methods: In a population-based ca

A low intake of calcium is widely considered to be a risk factor for future fracture. The aim of this study was to quantify this risk on an international basis and to explore the effect of age, gender and bone mineral density (BMD) on this risk. We studied 39,563 men and women (69% female) from six prospectively studied cohorts comprising EVOS/EPOS, CaMos, DOES, the Rotterdam study, the Sheffield

We conducted a first pilot study on healthy women living in two countries with different dietary habits, Granada in the south of Spain and Malmo in the south of Sweden, in order to compare their levels of plasma phospholipid fatty acids, and to examine the relationship between the differences in food consumption. This study is part of a pilot study which is nested in the European Prospective Inves

Streptococcus pneumoniae strains lacking the enzyme dihydrolipoamide dehydrogenase (DLDH) show markedly reduced ability to grow on raffinose and stachyose as sole carbon sources. Import of these sugars occurs through the previously characterized raffinose ATP-binding cassette (ABC) transport system, encoded by the raf operon, that lacks the necessary ATP-binding protein. In this study, we identifi

MR image nonuniformity can vary significantly with the spin-echo pulse sequence repetition time. When MR images with different nonuniformity shapes are used in a T1-calculation the resulting T1-image becomes nonuniform. As shown in this work the uniformity TR-dependence of the spin-echo pulse sequence is a critical property for T1 measurements in general and for ferrous sulfate dosimeter gel (FeGe

A method for analysing and comparing treatment planning system (TPS) data and ferrous dosimeter gel measurements evaluated with MRI (FeMRI) was developed, including image processing to final absorbed dose images. Measurements were analysed according to this method and FeMRI data were thereby compared with the TPS-calculated dose distribution. For photons, differences between FeMRI- and TPS dose da

The measurement of absorbed dose distributions using dosemeter gel and magnetic resonance imaging (MRI) in a standard geometry has been investigated. Absorbed depth-dose curves and profiles measured with this new technique show good agreement with corresponding measurements using diodes. This was proven in a 60Co beam as well as an electron beam. The dosemeter gel is made of agarose and ferrous su

The distribution of neurons expressing preproenkephalin (PPE) mRNA in the brain of the salmon was investigated by means of non-radioactive in situ hybridization, and directly compared with the distribution of enkephalin-immunoreactive (ENKir) neurons. This approach, utilized here for the first time in a non-mammalian vertebrate for the identification of neurons containing opioid peptides, permitte

The expression of mRNA coding for brain-derived neurotrophic factor (BDNF) and for its functional receptor, the full-length tyrosine kinase receptor trkB (trkB mRNA), was examined in early postnatal and adult rat retina by in situ hybridization using digoxygenin and radioactively-labeled oligonucleotide probes. BDNF and trkB mRNAs are expressed in the ganglion cell layer at postnatal-days (PN) 1,

Previous studies have identified an association between osteoporotic fracture and a polymorphism affecting a Sp1 binding site in the first intron of the collagen type I alpha 1 gene (COL1A1). It is currently unclear, however, whether this association is direct or the result of linkage disequilibrium with other polymorphisms situated nearby. In this study we analyzed the relationship between four w

Methylchloroisothiazolinone (MCI) and methylisothiazolinone (MI) are the active ingredients in commonly used preservative systems (e.g. Kathon CG(®) ). MCI/MI is present in the European baseline patch test series at 100 ppm aq. Since 1986, 200 ppm (dose 0.006 mg/cm(2) ) has been used in Sweden without causing skin irritation. Centres in Spain, the United Kingdom and Ireland have also used 200 ppm

Objective: Anaemia in low-risk MDS is associated with reduced quality of life (QoL). Response to treatment with erythropoietin (EPO) + G-CSF is associated with improved QoL, but whether transfusion therapy with higher haemoglobin (Hb) target levels has similar effects is unknown. The objective for this prospective phase II Nordic multicentre trial was to assess QoL, response rate and physical func

With the aid of time-resolved dynamic light scattering (DLS) and static light scattering (SLS), we have analyzed the ejection kinetics from the bacterial virus bacteriophage (or phage) lambda, triggered in vitro by its receptor. We have used DLS to investigate the kinetics in such a system. Furthermore, we have shown that both SLS and DLS can be interchangeably used to study the process of phage D

Cells in mitosis were harvested from exponentially growing Chinese hamster ovary cells by the mitotic detachment technique. Immediately after harvesting, the mitotic cells were seeded in tissue culture flasks and incubated at 37 degrees C in a CO2 incubator. Care was taken not to perturb the progression of cells through the cell cycle. At every hour after seeding for 14 h, cells were collected for

Inhibition of dipeptidyl peptidase-4 (DPP-4) is currently explored as a novel therapy of type 2 diabetes. The strategy has been shown to improve glycemia in most, but not all, rodent forms of glucose intolerance. In this study, we explored the effects of DPP-4 inhibition in mice with [beta-cell overexpression of human islet amyloid polypeptide (IAPP). We therefore administered the orally active an

Blood and serum samples from 372 15-year-old adolescents were collected in two cities in Sweden and analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The objective was to (1) determine the levels of 13 elements in blood and serum from the teenagers; and (2) for each element, investigate the correlation between the concentrations in blood and serum. The concentrations in blood and
