1. We investigated the individual and combined effects of two predators (the climbing perch, Anabas testudineus, and the wetland crab, Esanthelphusa nimoafi) indigenous to wetlands in Laos, on the behaviour and survival of the invasive South American golden apple snail (Pomacea canaliculata). The snail is considered a pest, consuming large amounts of rice and other aquatic vegetation in the region

Background:Whey proteins have insulinotropic effects and reduce the postprandial glycemia in healthy subjects. The mechanism is not known, but insulinogenic amino acids and the incretin hormones seem to be involved. Objective:The aim was to evaluate whether supplementation of meals with a high glycemic index (GI) with whey proteins may increase insulin secretion and improve blood glucose control

We report on likely mixed paternity in a natural population of snow skinks (Niveoscincus mirolepidoms) from alpine Tasmania, Australia. This species is nonterritorial and males guard females after copulation, Suggesting that guarding behavior has evolved to prevent rival mating of still-receptive females. To what degree does this mate-guarding prevent rival copulations? We sampled gravid females a

Popular Abstract in Swedish Cafeterian i Malmö Musikhögskola förvandlas två gånger om året till de passionerades mötesplats: När terminens ”Gambiastudenter” återvänder efter sina tre veckors fältarbete och skola med palmer som klassrumsväggar, möts de av veteranerna, de som redan varit där och som förstår att tolka entusiasmen. Det handlar inte om den vitalitet som alstrats av solen, färgerna och The present study seeks to examine attitudes to teaching and learning among jalis in the Gambia. Although this is the main focus, the horizon of which the study is carried out, analysed and discussed, is the development of music teacher education in Sweden during the last three decades, and of which I have been a participant. The intention of the study is to expand current views on music teaching

We present a novel method for monitoring isothermal lipid hydration using a sorption microcalorimeter. A measuring cell of the double-twin calorimeter consists of two vessels connected by a stainless steel tube. The upper vessel contains pure water, and the bottom vessel is loaded with the lipid sample. This calorimeter allows for simultaneous measurement of the partial molar enthalpy and the chem

Objective To discuss how to develop more effective treatment programmes than those currently available for addictive disorders. Data sources The Swedish SBU report, published in English in 2003. was used as a database. It includes 641 randomized controlled trials and seven longitudinal prospective studies. Methods Meta-analytical calculations were performed in several areas using standardized mean

This study investigates exposure to polybrominated diphenyl ethers (PBDEs) and tetrabromobisphenol A (TBBPA), which are used as flame retardants in electronic equipment, in a group of technicians with intense computer work. Thirteen PBDE congeners and TBBPA were quantified in serum from 19 computer technicians. Previously investigated groups of hospital cleaners with no computer experience, and cl

Female reproductive success in the unisexual perennial clonal moss Hylocomium splendens was examined by recording, if the segment was reproductive [produced sporophyte(s)] or not, together with several distance-to-male and male density variables, and segment size. This was done for every female segment in a population over a 5 year study period. A high fraction of the population could be sexed bec

INTRODUCTION: Patients with ulcerative colitis and primary sclerosing cholangitis have an increased risk of developing carcinoma both in the bile ducts and in the colon. PURPOSE: To investigate whether this patient group also has an increased risk of developing atrophy and neoplasia in the deal pouch mucosa after construction of a pelvic pouch with an ileoanal anastomosis or a continent Kock ileos

Background: In April 2002, the Swedish National Food Administration and a scientific group at the University of Stockholm jointly announced that they had shown acrylamide to be formed during the preparation of food and found it to occur in many foodstuffs. These new findings were clearly of concern to many types of industrial food processing as well as to home cooking. The Swedish Food Federation

The quantification of species along environmental gradients has long been the subject of study regarding natural plant communities and, more recently, ecosystems disturbed by anthropogenic emissions of eutrophying and acidifying substances. We studied 527 sites in southern Swedish deciduous forests divided into two regions, with mean nitrogen depositions of 17 and 9 kg ha(-1) y(-1). The higher dep

Retinitis pigmentosa comprises a heterogeneous group of incurable progressive blinding diseases with unknown pathogenic mechanisms. The retinal degeneration 1 (rd1) mouse is a retinitis pigmentosa model that carries a mutation in a rod photoreceptor-specific phosphodiesterase gene, leading to rapid degeneration of these cells. Elucidation of the molecular differences between rd1 and healthy retina

Organic carbon (C) in lakes originates from two distinct sources-primary production from within the lake itself (autochthonous supply) and importation of organic matter from the terrestrial watershed (allochthonous supply). By manipulating the C-13 of dissolved inorganic C, thereby labeling within-lake primary production, we examined the relative importance of autochthonous and allochthonous C in

n northern Europe, a long history of land use has led to profound changes within forest ecosystems. The white-backed woodpecker (Dendrocopos leucotos) is one of several specialised forest species whose populations have declined. Conservation management directed at this species’ habitat has made it a de facto umbrella species for conservation of the biodiversity associated with forests rich in deci

Endothelial and vascular smooth muscle cells express both estrogen receptor (ER) agr and beta. Recent findings indicate that vascular ERbeta and ERagr may substitute for one another. Here, we investigate vascular morphology, contractility and protein expression in intact aorta from adult (4 months old) female mice lacking both ERagr and ERbeta (DERKO). The body weights were 17% higher (P<0.01) in

The tumor growth phenotype was characterized in relation to concentration of circulating estradiol, estradiol receptor (ER) activation and progesterone receptor (PgR) induction. Ten tumor pieces from an ER and PgR positive human endometrial adenocarcinoma grown in non-oophorectomized nude mice for one year were randomly selected to grow during a preparation phase of 4 weeks either in oophorectomiz

The identification of novel tumour-associated antigens (TAAs) is pivotal for progression in the fields of tumour immunotherapy and diagnosis. In the present study, we have developed, based on flow cytometric evaluation and use of a mini-library composed of specific antibody clones linked to different antibiotic resistance markers, methods for positive and subtractive selection of phage antibodies

Background: There are two independent head injury outcome studies using the "Lund concept", and both showed a mortality rate of about 10%, and a favourable outcome (Glasgow outcome scale, GOS 4 and 5) of about 70%. The Lund concept aims at controlling intracranial pressure, and improving microcirculation around contusions. Intracranial pressure is controlled by maintaining a normal colloid osmotic

Colorectal cancer (CRC) is one of the major causes of cancer globally. Recent studies proposed a role for cancer initiating cells (CICs), a small subset of replication-competent cells, in colon carcinogenesis. Although the role of inflammatory lipid-mediators in CRC progression is well known, their role in the promotion of cancer-initiating cells remains to be elucidated. For this thesis, we inves
