The ability of calcium to suppress the secretion of parathyroid hormone (PTH) is impaired in primary hyperparathyroidism (pHPT). Whether the nonadenomatous glands in pHPT also exhibit altered calcium/PTH homeostasis is not known, but this may be the case since in the immediate postoperative period after surgery for pHPT, hypocalcemia often evolves in spite of a rapid normalization of serum levels

Objectives: We have observed clinical cases where bone is formed in the overlaying muscle covering surgically created bone defects treated with a hydroxyapatite/calcium sulphate biomaterial. Our objective was to investigate the osteoinductive potential of the biomaterial and to determine if growth factors secreted from local bone cells induce osteoblastic differentiation of muscle cells. Materials

Clasts in the CM2 carbonaceous chondrite Lonewolf Nunataks (LON) 94101 have been characterized using scanning and transmission electron microscopy and electron microprobe analysis to determine their degrees of aqueous alteration, and the timing of alteration relative to incorporation of clasts into the host. The provenance of the clasts, and the mechanism by which they were incorporated and mixed

A selection of searches by the ATLAS experiment at the LHC for the electroweak production of SUSY particles are used to study their impact on the constraints on dark matter candidates. The searches use 20 fb−1 of proton-proton collision data at s=8 TeV. A likelihood-driven scan of a five-dimensional effective model focusing on the gaugino-higgsino and Higgs sector of the phenomenological minimal s

When introduced in 1992, the Lund concept (LC) was the first complete guideline for treatment of severe traumatic brain injury (s-TBI). It was a theoretical approach, based mainly on general physiological principles-i.e., of brain volume control and optimization of brain perfusion and oxygenation of the penumbra zone. The concept gave relatively strict outlines for cerebral perfusion pressure, flu

A new system for photon induced fluorescence spectroscopy (PIFS) at the gas phase photoemission beamline (Elettra, Trieste) is described. It consists of a novel non-dispersive detector for VUV photons and a spectrometer for UV/visible light with cooled CCD detector. To illustrate the performance of the apparatus, the fluorescence decay of the doubly excited states of helium below the N = 2 ionizat

It is difficult to determine whether transient folding intermediates have a cooperative (or first-order) folding transition without measuring their rates of formation directly. An intermediate I could be formed by a second-order transition from a denatured state D that is progressively changed into I as conditions are changed. We have not been able to monitor the rate of formation of the folding i

The chromosomal location of six barley genes was determined by Southern blot experiments using wheat strains which contained the short or long arm from one of the seven barley chromosomes. The genes analysed encode enzymes that are required for chlorophyll and heme synthesis. Glutamyl-tRNAGlu synthetase, glutamate 1-semialdehyde 2,1-aminotransferase and glutamyl-tRNAGlu reductase are common to bot

Background Several models for prediction of acute coronary syndrome (ACS) among chest pain patients in the emergency department (ED) have been presented, but many models predict only the likelihood of acute myocardial infarction, or include a large number of variables, which make them less than optimal for implementation at a busy ED. We report here a simple statistical model for ACS prediction th

The aims of this study were: 1) to investigate whether single-limb stabilometry and a one-leg hop test are influenced by age, sex, height, weight or activity level in healthy subjects, 2) to examine possible differences between the right and the left leg, 3) to determine Limb Symmetry Index (LSI) values, and 4) to study the relation between the stabilometric variables, that is, average speed (AS)

The study aims at investigating the use of Landsat thematic mapper (TM) for mapping leaf area index (LAI) in coniferous and deciduous forests in southern Sweden. LAI has been estimated in the field with optical measurements, allometric equations, and litter-trap data, and empirical relationships between LAI estimates and satellite-measured reflectances have been analysed. Several common vegetation

Extraction systems for hydrophobically tagged proteins have been developed based on phase separation in aqueous solutions of non-ionic detergents and polymers. The systems have earlier only been applied for separation of membrane proteins. Here, we examine the partitioning and purification of the amphiphilic fusion protein endoglucanase I(core)-hydrophobin I (EGI(core)-HFBI) from culture filtrate

We found that the Black grouse (Tetrao tetrix) possess low numbers of Mhc class II B (BLB) and Y (YLB) genes with variable diversity and expression. We have therefore shown, for the first time, that another bird species (in this case, a wild lek-breeding galliform) shares several features of the simple Mhc of the domestic chicken (Gallus gallus). The Black grouse BLB genes showed the same level of

In Sweden a new red list was issued 2000, but there is no published list of the most important areas for biodiversity preservation. I use woodliving and red-listed beetles as indicators of “hot-spots” for biodiversity preservation, since these insects constitute a large proportion of the red-listed forest living species in Sweden. Based on museum and many large private collections of beetles from
