The vacancy-dioxygen complex (VO2) is one of the main defects formed in irradiated Cz-Si crystals upon annealing (or irradiation) in the temperature range 300-400degreesC. In this defect two oxygen atoms share a vacancy, each bonded to two silicon neighbors. Independent vibrations of these 0 atoms give rise to one infrared absorption band at 895.5 cm(-1) at 10 K. We report on an experimentally dis

We present the results of the first search for gravitational wave bursts associated with high energy neutrinos. Together, these messengers could reveal new, hidden sources that are not observed by conventional photon astronomy, particularly at high energy. Our search uses neutrinos detected by the underwater neutrino telescope ANTARES in its 5 line configuration during the period January - Septemb

Dendritic cells (DC) undergo complex developmental changes during maturation. The MHC class H (MHC H) molecules of immature DC accumulate in intracellular compartments, but are expressed at high levels on the plasma membrane upon DC maturation. It has been proposed that the cysteine protease inhibitor cystatin C (CyC) plays a pivotal role in the control of this process by regulating the activity o

Conidiation in A. cichorii Nattras is reversibly stimulated by near UV radiation (NUV .apprx. 313 nm) and inhibited by blue light (.apprx. 450 nm) and apparently is a mycochrome-mediated process. After induction with plane-polarized NUV, blue light polarized perpendicularly to the NUV was more effective in counteracting the induction than was blue light polarized parallel to the NUV. Both the blue

Glyceryl monooleate (GMO) and other unsaturated long-chain monoglycerides show peculiar phase behaviour characterised by the presence of one or more cubic liquid-crystalline phases. In the present study, hydrolysis of cubic lipid-water phases formed by GMO were determined. Human pancreatic carboxyl ester lipase (CEL), colipase-dependent lipase with colipase, human duodenal contents and rat pancrea

Popular Abstract in Swedish Bröstcancer är den vanligaste cancersjukdomen hos kvinnor i västvärlden och årligen nydiagnosticeras omkring 7000 patienter, bara i Sverige. Antalet nyinsjuknade ökar för varje år medan dödligheten sjunker och de främsta orsakerna till detta tros vara förbättrad diagnostik via mammografiscreening och nya behandlingsmöjligheter. Bröstcancer behandlas primärt med kirurgi,It is well-known that a majority of breast cancers are hormone-dependent, making endocrine therapy an important adjuvant treatment after surgery. Susceptibility to endocrine treatment is determined by the presence of estrogen receptors (ER) and progesterone receptors (PR) in the tumors. Tamoxifen is the most well-established endocrine treatment available, inhibiting tumor growth and improving surv

A new method for extracting seasonality information from time-series of satellite sensor data is presented. The method is based on nonlinear least squares fits of asymmetric Gaussian model functions to the time-series. The smooth model functions are then used for defining key seasonality parameters, such as the number of growing seasons, the beginning and end of the seasons, and the rates of growt

C4b-binding protein (C4BP) is an important plasma inhibitor of the classical pathway of complement activation. Several bacterial pathogens bind C4BP, which may contribute to their virulence. In the present report we demonstrate that isolated type IV pili from Neisseria gonorrhoeae bind human C4BP in a dose-dependent and saturable manner. C4BP consists of seven identical alpha-chains and one beta-c

Background-Conjugated linoleic acids (CLAs), a group of fatty acids shown to have beneficial effects in animals, are also used as weight loss supplements. Recently, we reported that the t10c12 CLA-isomer caused insulin resistance in abdominally obese men via unknown mechanisms. The aim of the present study was to examine whether CLA has isomer-specific effects on oxidative stress or inflammatory b

Aims: This study explores the knowledge, attitudes and practices among Somali and Sudanese immigrants in Denmark with regard to HIV/AIDS and condom use. Material and methods: A 78-item questionnaire, divided into five thematic sections, was given to 192 purposively selected Sudanese and Somalis of both sexes, aged 18-49, who had lived in Denmark for one or more years. It was administered in Arabic

Policies for handling cases of penicillin-non-susceptible Streptococcus pneumoniae (PNSP) in day-care groups vary between different counties in Sweden. The aim of this study was to evaluate the epidemiological effect of excluding PNSP-carriers from children's day-care centres (DCC). We followed the incidence in 14 DCC groups with ongoing PNSP-spread, by repeated group screens until no further case

We present a review and our own experience of the demographic aspects of popliteal artery aneurysms (PAAs), their clinical presentation, the treatment alternatives and associated outcome. The incidence of PAAs varies between 0,1-1%. 95% of the patients are male. 50% are asymptomatic at the time of diagnosis. Annually, 5-24% of PAAs develop symptoms. The clinical presentation varies widely with an

Popular Abstract in Swedish Antalet fallolyckor och frakturer ökar ibland den äldre befolkningen och detta innebär en ökande social och ekonomisk belastning för samhället. En viktig orsak till fallolyckor kan vara dålig balans. Kontrollen av upprätt stående och gångförmåga baseras på komplexa processer av neuromuskulär aktivitet. Denna neuromuskulära aktivitet bygger på sensorisk information från Control of the upright stance and locomotion is a complicated process of muscular activity. The muscular activity is dependant on afferent information from the different sensory organs and interpretation in the central nervous system. Age-related degenerative changes exist in all the domains concerned with control of posture. The aims of the studies were to investigate if suspected age-related de

We have developed software, called UNHLATEXTM> KMORPH, for predicting particle morphology development under conditions of kinetic control. In order to accomplish this, one must first simulate the polymerization kinetics and as a result KMORPH has developed into a fairly complete model for seeded emulsion polymerization kinetics. The simulation takes into account both the aqueous phase and particle

We assessed the influence of timing of harvests on an age-structured population by altering the order of the harvest in relation to density-dependent recruitment and winter mortality. To analyze the effects of harvest timing on a general population of stream salmonids with five age-classes, we used three management strategies: no minimum size limits and two minimum size limits with increasing degr
