A multicentre, randomized, double-blind, crossover study was designed to investigate the effects of prednisone on allergic and irritant patch test reactions. 24 subjects with known allergy to nickel were recruited and patch tested with a nickel sulfate dilution series in aqueous solution, 5% nickel sulfate in petrolatum and 2 dilution series of the irritants nonanoic acid and sodium lauryl sulfate

The phylogeny of the lichen family Candelariaceae was investigated using nucleotide sequences from the ITS region of the nuclear ribosomal DNA. 23 species of Candelariella, 6 species of Candelaria, 2 species of Candelina and 2 species of Placomaronea were included in the study. Acarospora cervina and Pleopsidium chlorophanum were used as outgroup species. The phylogenetic analysis were performed u

Pregnancy is rare in Parkinson's disease (PD). In the literature on studies of antiparkinsonian drugs in animals during pregnancy, there are reports on malformations of the skeletal and circulatory system. However, the majority of studies in animals have not shown any teratogenicity. Amantadine has been teratogenic in rats and selegiline has caused neurochemical and behavioral alterations in rats

The complex between calmodulin and the calmodulin-binding portion of smMLCKp has been studied. Electrostatic interactions have been anticipated to be important in this system where a strongly negative protein binds a peptide with high positive charge. Electrostatic interactions were probed by varying the pH in the range from 4 to 11 and by charge deletions in CaM and smMLCKp. The change in net cha

The ultrastructural cytology and reproduction of the hyperparasitic microsporidium Amphiamblys copitellides (Caullery and Mesnil, 1897) is described. Merogonial reproduction was not observed. The sporogony comprises two sequences: a sac-bound sporogony in close contact with the cytoplasm of the host and a free sporogony in parasitophorous vacuoles. The free sporogony, which probably precedes the s

The degree of immunoreactive connexin43 (C x 43) in rat lung was evaluated during the development of radiation-induced pulmonary fibrosis in rat by a double immunofluorescence technique using polyclonal antisera to Cx43 and monoclonal antibodies to cytokeratins on cryostat sections. In normal rat lungs, Cx43 was detected in pneumocytes type II and I, in large blood vessel endothelia, in peribronch

Background: Multimorbidity and illness will become more common due to increased life expectancy. Purpose: This study describes various combinations of diseases and symptoms and explores implications for survival in a sample of 80 year-olds followed up to 95 years of age. Furthermore, reported subjective health, coping, and life satisfaction is explored. Method: 212 persons, born in 1908, were cl

Recent literature on L2 vocabulary testing points to a move away from discrete vocabulary testing towards more embedded and integrative approaches. This paper investigates if the way vocabulary is currently tested at English departments at Swedish universities follows this trend. The survey shows that a great majority of universities use discrete and selective vocabulary tests and that the multipl

A measurement of the positive streamer charge has been performed at atmospheric conditions in a quasi-uniform electric field where the discharge was electrically triggered. By applying a square impulse voltage to the trigger electrode, which was close to, but electrically isolated from, the anode, a positive streamer discharge with one discharge event was produced. The voltage, current and luminos
