A commonly practiced method intended to reduce mortality from recreational fisheries is mandatory (e.g., small fish protected by minimum-size limits) or voluntary catch-and-release (C&R), where fish are caught with hook and line and released alive on the assumption that fish survive unharmed. C&R can, however, have both lethal and sub-lethal consequences for fish, with altered behaviour se
Abstract The last few years have seen an increase in the variety of in vivo experiments used for studying cerebellar physiological mechanisms. A combination of ketamine and xylazine has become a particularly popular form of anesthesia. However, because nonanesthetized control conditions are lacking in these experiments, so far there has been no evaluation of the effects of these drugs on the physi
A new type of fibre-based anion-exchange material for plasmid purification was developed. The basic material consisted of non-porous silica fibres with a mean diameter of 1.5 mu m and a surface area of 2.4 m(2) g(-1). The fibre surface was provided with several types of ligands, either by adsorption of polymers (chitosan or poly(ethyleneinune)) or by polymerization of amine-containing acrylic mono

The increasing industrial application of metal oxide Engineered Nano-Particles (ENPs) is likely to increase their environmental release to soils. While the potential of metal oxide ENPs as environmental toxicants has been shown, lack of suitable control treatments have compromised the power of many previous assessments. We evaluated the ecotoxicity of ENP (nano) forms of Zn and Cu oxides in two di
Objective: The objective of this study was to assess the level of agreement between stroke subtype classifications made using the Trial of Org 10172 Acute Stroke Treatment (TOAST) and Causative Classification of Stroke (CCS) systems. Methods: Study subjects included 13,596 adult men and women accrued from 20 US and European genetic research centers participating in the National Institute of Neurol
The activity of heterotrophic soil microorganisms is usually limited by the availability and quality of carbon (C). Adding organic substances will thus trigger a microbial response. We studied the response in bacterial growth and respiration after the addition of low amounts of glucose. First we determined if additions of glucose, at concentrations which did not result in an exponential increase i
Fermented milk is commonly eaten during breakfast or as a snack between meals either in one-portion cups or from a bowl with a spoon. Approximately 5-10% of the fermented milk remains in the packages upon pouring, which during the last years, has received attention in public media as newspapers and television. This is a problem, not only from an economical point of view, but also from an ecologica
A method is described in which light gradients and spectral regime can be measured within plant tissue using fiber optics. A fiber optic probe was made by modifying a single optical fiber (200 μm diameter) so that it had a light harvesting end that was a truncated tip 20–70 μm in diameter. The probe was a directional sensor with a half-band acceptance angle of 17–20°. Light measurements were made
Traditional measures for improved traffic safety need to be complemented by modern technologies in the struggle to reduce the consequences of traffic accidents all over the world. This thesis introduces the Loyal Speed Adaptation (LSA) function based on recent developments in the area of Intelligent Transport Sys-tems to support the vehicle drivers in not using inappropriate or excessive speeds, w
The nitrate reductase activity (NRA) was measured during spring, early summer and late summer in three deciduous forests, where the tree layer was dominated by oak. The nitrate assimilation capacities of the compartments of the above-ground and below-ground biomass of the understory and of the leaves and roots of the tree layer were calculated as NRA per unit biomass and NRA per unit area. The NRA
Acetone-ether preparations of epididymal fat pads from fasted or fed rats contained two enzymes catalyzing the hydrolysis of long-chain monoacylglycerols. The enzymes were identified as monoacylglycerol lipase (Tornqvist, H. and Belfrage, P., (1976) J. Biol Chem. 251, 813--819) and lipoprotein lipase by their apparent pI values after electrofocusing in non-ionic detergent, selective inhibition pro
OBJECTIVE: Endoleaks and endotension are critically important complications of some endovascular aortic aneurysm repairs (EVARs). For the resolution of controversial issues and the determination of areas of uncertainty relating to these complications, a conference of 27 interested leaders was held on November 20, 2000. METHODS: These 27 participants (21 vascular surgeons, five interventional radio
In our previous paper [M.A. Borowiak, M.H. Jamroz, R. Larsson, J. Mol. Catal. A: Chem., 139 (1999) 97], an impulse-oscillation model (IOM) was used for a time description of catalytic acts in the reactions of catalytic decomposition of formic acid on oxide catalysts for unimolecular mechanism. In this paper: the bimolecular mechanism were modelled for the same reactions. The results of IOM calcula
Background: Oxidation of LDL is associated with generation of autoantibodies against a large number of different aldehyde-modified peptide sequences in apo B-100. Autoantibodies recognizing peptide sequences in the LDL receptor-binding region of apo B-100 could potentially affect both cholesterol metabolism and atherosclerosis. The aim of the present study was to determine physiological effects of
Intestinal spirochetes (Brachyspira spp.) are causative agents of intestinal disorders in animals and humans. Phylogenetic analysis of cloned 16S rRNA genes from biopsies of the intestinal mucosa of the colon from two Swedish 60-years old adults without clinical symptoms revealed the presence of intestinal spirochetes. Seventeen clones from two individuals and 11 reference strains were analyzed an
Whey protein adsorption on stainless steel surfaces was investigated by in situ ellipsometry under well-defined flow conditions and protein solution residence times. The size distribution in solution of the protein aggregates formed under the same conditions was determined by dynamic light scattering. The adsorption was performed at 72 degrees C and 85 degrees C which is below and above the unfold
A novel electrode array was developed based on the XNA on Gold(TM) microarray platform. The platform combines self-assembling monolayers, thick film patterning and streptavidin based immobilization to provide a robust, versatile platform capable of analysing virtually any biomolecule including nucleic acids, proteins, carbohydrates and lipids. Electrochemical analysis of the self-assembling monola
Heat shock proteins counteract heat and oxidative stress. In chloroplasts, a small heat shock protein (Hsp21) contains a set of conserved methionines, which date back to early in the emergence of terrestrial plants. Methionines M49, M52, M55, M59, M62, M67 are located on one side of an amphipathic helix, which may fold back over two other conserved methionines (M97 and M101), to form a binding gro
