UV-induced changes in pigment content and light penetration in the fruticose lichen Cladonia arbuscula ssp. mitis

The response of the lichen, Cladonia arbuscula (Wallr.) Flot. ssp. mitis (Sandst.) Ruoss to enhanced UV-B (280-315 nm) radiation was investigated with respect to: (a) changes in phenolic content; (b) differential pigment accumulation under visible and UV radiation with increasing distance from thallus apices; and (c) the internal distribution of UV-B radiation within the thallus measured with quar

Gastrectomy has no effect on bone regeneration in rats despite a decrease in bone mass

Background: Gastrectomy, specifically the removal of the acid-producing part of the stomach (fundectomy), is known to cause osteopenia. This effect has been ascribed to the elimination of a hypothetical osteotropic peptide hormone, presumably produced in the oxyntic mucosa. Since osteopenia is due to a disturbed balance between bone formation and resorption, we assessed the effect of gastrectomy o

Physics with REX-ISOLDE and MINIBALL

REX-ISOLDE is an experiment at ISOLDE/CERN with the aim to study the nuclear structure of neutron-rich nuclei using radioactive ion beams up to 2.2 MeV/u. The highly-efficient gamma-ray detector set-up MINIBALL will be used to explore reactions induced by Coulomb excitation or neutron transfer.

Ansträngningsutlöst värmeslag gav svår lever- och njursvikt. Leverdialys med MARS prövades för första gången vid detta tillstånd

We present a case of exertional heatstroke, uncommon in the Scandinavian climate zone. Despite early recognition and treatment, our patient underwent a complex clinical course with both renal and liver failure, requiring 4 months of hospital stay and a convalescens of more than a year. In previous reported cases of severe liver failure following exertional heatstroke, liver transplantation has bee

Lower Extremity Function in Arthritis

The aim of this thesis was to develop and apply self-registered and observed measures of physical function in people with arthritis in the lower extremity. In Paper I, 181 subjects from the Swedish Knee Arthroplasty Register who were satisfied with their primary knee arthroplasty were studied. 44% of the medical records included reports of pain in the replaced knee at the same time as the patient

Glucose levels and insulin secretion during a 75 g glucose challenge test in normal pregnancy

OBJECTIVES: The aim of the study was to evaluate glucose levels and insulin secretion early in pregnancy and at a time when gestational diabetes mellitus frequently occurs in order to define reference values for glucose tolerance during pregnancy. The results were also related to maternal factors that might identify subjects at risk of developing gestational diabetes mellitus as well as foetal fac

Chromosomal abnormalities in inflammatory pseudotumor of the urinary bladder

Inflammatory pseudotumors of the urinary bladder are rare, benign, nonepithelial tumors. Fewer than 30 have been reported, and no data are available on their karyotypic characteristics and/or the molecular mechanisms of pathogenesis. We performed short-term culturing and cytogenetic analysis of an inflammatory pseudotumor of the bladder, finding a der(20)t(12;20)(q13similar toq15;q13) as the only

Two-dimensional gel electrophoresis of proteins and peptides in bovine milk

Proteins and peptides in bovine milk and colostrum were separated by two-dimensional gel electrophoresis (2-DE). The proteins were separated in the first dimension by isoelectric focusing in the pH ranges 4-7 and 6-11, and in the second dimension by sodium dodecyl sulphate polyacrylamide gel electrophoresis on 12.5% T homogeneous gels. The peptides were separated in the pH range 3-10 in the first

Determination of hexahydrophthalic acid and methylhexahydrophthalic acid in plasma after derivatisation with pentafluorobenzyl bromide using gas chromatography and mass spectrometric detection

A method for the simultaneous determination of hexahydrophthalic acid (HHP acid) and methylhexahydrophthalic acid (MHHP acid) in human plasma was developed. The procedure was a rapid, single step extractive derivatisation with pentafluorobenzyl bromide as the derivatisation agent. The formed pentafluorobenzyl esters were analysed by gas chromatography-mass spectrometry in negative ion chemical ion

Cooling enhances alpha 2-adrenoceptor-mediated vasoconstriction in human hand veins

The contribution of different receptor subtypes in the contractile response during cooling in human hand vessels is of considerable interest in the understanding of cold-induced peripheral vasospasm as it appears in Raynaud's phenomenon. Subcutaneous vein segments from 50 patients undergoing hand operations not related to vascular disorders were examined in vitro. The temperature in the organ bath
