We use the assignment technique and a new approach, the 'novel allele technique', to detect sex-biased dispersal in great reed warblers Acrocephalus arundinaceus . The data set consisted of immigrants and philopatric birds in a semi-isolated population in Sweden scored at 21 microsatellite loci. Fourteen cohorts were represented of which the four earliest were used to define a reference population

The urinary excretion of a glucose-containing oligosaccharide, Glc alpha[1-6Glc alpha[1-4Glc alpha[1-4Glc, (Glc4) has been measured in various physiological and pathological conditions. The Glc4 content of 24 h samples from the same individual was relatively constant, whereas 2 h samples showed up to 4-fold variations in Glc4 concentration. This variation is associated mainly with increased excret

Levels of hydrolytic enzymes increase in skeletal muscle after denervation and their activities in the extracellular matrix appear to be important for interaction between muscle and nerve. Using enzymatic assays for beta-glucuronidase, beta-galactosidase, and plasminogen activator, we show that secretion of these enzymes from mouse skeletal muscle increases after denervation and that drugs interfe

Mutations in the genes that code for collagen VI subunits, COL6A1, COL6A2, and COL6A3, are the cause of the dominantly inherited disorder, Bethlem myopathy. Glycine mutations that interrupt the Gly-X-Y repetitive amino acid sequence that forms the characteristic collagen triple helix have been defined in four families; however, the effects of these mutations on collagen VI biosynthesis, assembly,

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

A follow-up liver biopsy was done 9-16 years (mean 12 years) after initial biopsy in 20 untreated Swedish patients infected with hepatitis C (8 men, 12 women; mean age 30 years at initial biopsy) in whom first biopsy had been classified as chronic persistent hepatitis. A significant progression of liver damage was found when using Histology Activity Index (HAI) scoring according to Knodell (p=0.00

The single-trial emotional Stroop effect for masked threat words, and its association with anxiety, anger, and depression was studied in a group of men (n = 24) and women (n = 24) while controlling for possible differential thresholds for threat words vs. neutral words. Stroop interference for masked threat words was found to correlate with trait anxiety, and the effect could not be explained by a

Transforming growth factor (TGF)-beta regulates vascular development through two type I receptors: activin receptor-like kinase (ALK) 1 and ALK5, each of which activates a different downstream Smad pathway. The endothelial cell (EC)-specific ALK1 increases EC proliferation and migration, whereas the ubiquitously expressed ALK5 inhibits both of these processes. As ALK1 requires the kinase activity

BACKGROUND: Ventilator resetting is frequently needed to adjust tidal volume, pressure and gas exchange. The system comprising lungs and ventilator is so complex that a trial and error strategy is often applied. Comprehensive characterization of lung physiology is feasible by monitoring. The hypothesis that the effect of ventilator resetting could be predicted by computer simulation based on a phy

This study aims to analyse mental symptoms, psychotropic drug use and alcohol consumption, in immigrant women born in Finland, the other Nordic countries, Eastern Europe, Western Europe and countries outside Europe, compared with Swedish-born women, and furthermore, to study if age at immigration may have an influence. All women (n = 10,766) aged 50 - 59 years and living in the Lund area of southe

BACKGROUND: If lungs from subjects dying of heart attacks could be used for transplantation, the lung donor shortage could be radically reduced. The aim of this study was to investigate, in an experimental survival model, the results of lung transplantation using lungs from non-heart-beating donors. METHODS: The left lung, topically cooled to 25 degrees C for 2 hours in situ after 5 minutes of cir

Homosexual mounting is a common behaviour in bed bugs as male sexual interest is directed towards any newly fed individual. The only mode of copulation in the common bed bug, Cimex lectularius, is by traumatic insemination, where the male pierces the female abdomen with his needle-like penis. Homosexual mating would result in abdominal injuries in mounted males, as males lack the female counterada

In response to the pressures of predation, parasitism and competition for limited resources, several groups of (mainly) tropical bees and wasps have independently evolved a nocturnal lifestyle. Like their day-active (diurnal) relatives, these insects possess apposition compound eyes, a relatively light-insensitive eye design that is best suited to vision in bright light. Despite this, nocturnal be

We studied Great Reed Warblers Acrocephalus arundinaceus at two localities in Ghana during the winter. In the north (Tono), the birds arrived from late September and conducted a rapid moult soon after arrival. Towards the end of moult, birds accumulated fat and disappeared from the site. In the south (Tafo), birds arrived from mid-November in fresh plumage. This seemed to be the final wintering ar

A machine-learning and a string-matching approach to automated subject classification of text were compared, as to their performance, advantages and downsides. The former approach was based on an SVM algorithm, while the latter comprised string-matching between a controlled vocabulary and words in the text to be classified. Data collection consisted of a subset from Compendex, classified into six

Free fatty acids (FFA) have generally been proposed to regulate pancreatic insulin release by an intracellular mechanism involving inhibition of CPT-1. The recently de-orphanized G-protein coupled receptor, FFA(1)R/GPR40, has been shown to be essential for fatty-acid-stimulated insulin release in MIN6 mouse insulinoma cells. The CPT-1 inhibitor, 2-bromo palmitate (2BrP), was investigated for its a

The cysteinyl leukotriene(1) (CysLT(1)) receptor (CysLT(1)R) enhances survival and proliferation of intestinal cells via distinct pathways. Here, we have demonstrated that there is significant endogenous production of CysLTs from both non-tumour-and tumour-derived intestinal epithelial cells. Treatment of two non-tumour cell lines, Int 407 and IEC-6, with CysLT1R antagonists led to shrinkage and d

The involvement of the TP53 tumor suppressor gene in uterine corpus cancer was investigated by single-stranded conformation polymorphism and sequence analysis of its exons 4 to 10. Mutations were found in 12 (18.5%) of 65 cases. Ten of these 12 were single-base substitutions (8 missense and 2 nonsense mutations), whereas 2 were frame-shifting mutations. TP53 gene mutations correlated significantly
