Various methods for deriving atomic partial charges from the quantum chemical electrostatic potential and moments have been tested for the sucrose molecule. We show that if no further information is used, the charges on some carbon atoms become large and charge patterns involving these atoms are badly determined and poorly transferable. Adding lone-pairs on the ether oxygen atoms or dividing the m
Pre-fractionation of a complex mixture of proteins increases the resolution in analytical separations of proteins from cells, tissues or organisms. Here we demonstrate a novel method for pre-fractionation of membrane proteins by a detergent-based aqueous two-phase system. Membrane proteins are strongly under-represented in proteomic studies based on two-dimensional electrophoresis (2-DE). As a mod
A published investigation in 1961 of the vegetation on 10 burial mounds in southern Zealand was repeated in 2000. The burial mounds were situated as islands in the intensively used arable landscape. It is likely that such small fragments receive great inputs of Nitrogen by wet deposition and spill-over of artificial fertiliser from the surrounding fields. It was hypothesised that burial mounds in
Liquid-liquid partition chromatography in an aqueous poly(ethylene glycol)/dextran two-phase system (LLPC) is shown to be a quick and sensitive method for detecting conformational changes occurring upon binding of ligands by biospecific molecules. Two groups of well-characterized proteins, enzymes and monoclonal antibodies, were employed. As an example, LLPC demonstrated that isoforms of lactate d
På senare år har en rad alternativa terapiformer vuxit fram: Kyrkan och den traditionella psykoterapin har fått konkurrens av ”må bra-marknadens” rituella snabbterapier. Eftersom riterna syftar till att hela existentiellt utarmade eller stressade medborgare borde de vara välkomna inslag i samhället, men finns det skäl att kritisera dem. De lösningar som erbjuds individen är också de som bäst gagn
The early Church was a narrative fellowship which narrativized the Jesus tradition and per-formed it from memory. It did so by using specific narrative and mnemonic forms of commu-nication. The chreia combines features of narrativity, oral performance, and memory and con-stituted a basic element of the narrative mosaic of the Church. The author of the Gospel of Mark indicates a broader pattern of
Background. Nausea and vomiting in pregnancy (NVP) is a common complaint but risk factors for NVP are not well characterized. Methods. Occurrence of NVP was studied by questionnaires given to pregnant women at their first visit to the antenatal care unit and were returned around gestational week 28. Results. Analysis of 3675 completed questionnaires was made. Nausea and vomiting in pregnancy was
1. The influence of light, temperature, sediment mixing and sediment origin (water depth) on the recruitment of the cyanobacterium Gloeotrichia echinulata was examined in the laboratory. 2. Light and temperature were the most important factors initiating germination in G. echinulata. 3. The extent of germination (recruited biovolume) was mainly regulated by temperature and sediment mixing. Further
Supersingular H-n rank one perturbations of an arbitrary positive self-adjoint operator A acting in the Hilbert space H are investigated. The operator corresponding to the formal expression A(alpha) = A + alpha(phi,.)phi, alpha is an element of R, phi is an element of H-n (A), is determined as a regular operator with pure real spectrum acting in a certain extended Hilbert space H superset of X The
Popular Abstract in Swedish Syftet med denna studie var att: (I) undersöka förekomsten av höftartros på Island i jämförelse med södra Skandinavien, (II) utreda frekvensen av operation med total höftledsplastik (THP) för artros på Island, (III) jämföra två olika metoder för bedömning av höftartros med röntgenbilder, (IV) i en populationsbaserad studie påvisa förekomsten av ärftlighet för höftartrosHereditary factors are suggested to contribute to osteoarthritis (OA), but their relative importance is uncertain. Moreover, the underlying specific variations at the genome level remain unknown. The prevalence of hip OA in Iceland was assessed by examining colon radiographs and was found to be at least 5-fold higher compared to Sweden and Denmark. The age-standardized incidence of total hip repl
Four conserved disulfide bonds and N-linked and O-linked glycans of extracellular fungal peroxidases have been identified from studies of a lignin and a manganese peroxidase from Trametes versicolor, and from Coprinus cinereus peroxidase (CIP) and recombinant C. cinereus peroxidase (rCIP) expressed in Aspergillus oryzae. The eight cysteine residues are linked 1-3, 2-7, 4-5 and 6-8, and are located
BACKGROUND: Inflammation and immune responses are considered to be very important in the pathogenesis of atherosclerosis. Lipid accumulation in macrophages of the arterial intima is a characteristic feature of atherosclerosis which can influence the inflammatory potential of macrophages. We studied the effects of lipid loading on the regulation of TNF expression in human monocyte-derived macrophag
Over the last two decades there has been a striking and continuous increase in the prevalence of obesity both in industrialized and developing countries. Despite this global consistency there is a variation within countries with a higher prevalence of obesity within rural areas. The overall aim was to explore the prevalence of obesity and factors that influence the development of obesity in a rura
When water is coadsorbed with oxygen at coverages above 0.25ML an intact water species is observed in high resolution X-ray photoelectron spectroscopy up to 220 K, which is significantly more stable than intact water on the clean surface. The presence of this species causes a shift in the O 1s binding energy of the pre-adsorbed oxygen, which indicates the formation of hydrogen bonds between the tw
