This study aimed to evaluate the association between objectively measured habitual physical activity and calcaneal and forearm bone mineral density (BMD, g/cm(2)), one mechanically more loaded and one less loaded skeletal region, in children aged 6-8 years. BMD was measured in 297 boys and 265 girls by peripheral dual-energy X-ray absorptiometry in the forearm and calcaneus. An accelerometer regis

OBJECTIVE: To identify perinatal factors associated with cerebral palsy (CP). METHODS: This was a case-control study based on the Swedish Medical Birth Registry and the Swedish Hospital Discharge Registry, including 2,303 infants born in Sweden 1984-1998 with a diagnosis of CP and 1.6 million infants without this diagnosis. Odds ratios (ORs) with 95% confidence intervals (Cis) were calculated. RES

The Perstorp, industrial park in southern Sweden is faced with water shortage problems. One way to reduce these problems is through the reuse of recycled water. In this paper the results of treating 240 m(3) per day wastewater in a reverse osmosis (RO) plant are presented. High-quality water, which is used as make-up water in cooling towers, is produced from a difficult and varying feed. Severe fo

Ring segments (I mm in diameter) of the pulmonary artery obtained from 16 patients undergoing thoracic surgery were mounted in tissue baths. Cumulative concentration-response curves of some prostanoids and amines were obtained, and Emax and pEC50 values calculated. Noradrenaline, phenylephrine, clonidine and serotonin (5-HT) showed low intrinsic activities. Prostaglandin F2 alpha (PGF2 alpha) indu

Endometrial angiogenesis is not well studied, but has potential as a model for studies of physiological angiogenesis. Migration as well as proliferation of vascular endothelial cells are modulated by other endometrial cells. This study analyzes the chemotactic signal released from endometrial tissue in a wound assay using human microvascular endothelial cells. Endometrial tissue explants stimulate

The pharmacokinetics of antimigraine drugs zolmitriptan and sumatriptan varied considerably with a fourfold to 10-fold variation in plasma levels. In addition, the pharmacodynamics of triptans as investigated in vitro also varied considerably. In theory, there should probably be a 10-fold variation in doses available, but in clinical practice a fourfold difference in doses will probably cover the

Dishwashers are used in central hospital kitchens and ward kitchens to provide clean crockery. Soil recipes based on international standards were tested in order to evaluate the performance of a general dishwasher. In normal use of dishwashers, adherent soils are left on the crockery before cleaning. Different adherent soils, both with and without bacterial. contamination, were used to show the ef

Two real-time digital imaging systems, able to replace conventional autoradiography for radioactive hot particle separation and identification, are presented in this paper. The hot plutonium particles used for the study originate from the Thule nuclear weapon accident, Both of the real-time imaging techniques are initiated with sample splitting and measurements with a HPGe detector. in order to de

Sweden's decision to choose neutrality as its security policy orientation in the first half of the nineteenth century is explained with the help of image theory. It is argued that a theory focusing on the images of policy-makers regarding self, others and situation provides a better explanation of these strategic decisions than traditional balance-of-power theories. The important role of enemy-ima

Three-dimensional numerical simulations with CO⁵, a newradiation hydrodynamics code, result in a dynamic, thermally bifurcatedmodel of the non-magnetic chromosphere of the quiet Sun. The 3D modelincludes the middle and low chromosphere, the photosphere, and the topof the convection zone, where acoustic waves are excited by convectivemotions. While the waves propagate upwards, they steep

Hematologic malignancies are characterized by fusion genes of biological/clinical importance. Immortalized cell lines with such aberrations are today widely used to model different aspects of leukemogenesis. Using cDNA microarrays, we determined the gene expression profiles of 40 cell lines as well as of primary leukemias harboring 11q23/MLL rearrangements, t(1;19)[TCF3/PBX1], t(12;21)[ETV6/RUNX1]

Background, Aims and Scope. Using renewable feedstock and introducing biocatalysts in the chemical industry have been suggested as the key strategies to reduce the environmental impact of chemicals. The Swedish interdisciplinary programme 'Greenchem', is aiming to develop these strategies. One target group of chemicals for Greenchem are wax esters which can be used in wood surface coatings for woo

Den elektroniska revolutionen har satt gränsen mellan original och kopia i fråga. Musikindustrin har därför drabbats av ett akut problem, för vem har rätt till vad när upphovsmannaskapet är oklart?
