Seasonal variation in home-range size and habitat area requirement of lesser spotted woodpeckers (Dendrocopos minor) were studied by radio-tracking in southern Sweden for 6 years. Home-range size did not vary between age-groups or sexes, but varied with season and decreased successively from 742 ha in winter (n = 10), 355 ha in early spring (n = 15), 103 ha in late spring (n = 22) to 43 ha during
According to the leading hypothesis on testicular cancer (TC) etiology exposure to a specific pattern of steroid hormones in utero, in particular, to high levels of estrogens and low levels of androgens is the major determinant of TC risk in the offspring. We performed a case-referent study nested within Finnish, Swedish and Icelandic maternity cohorts exploiting early pregnancy serum samples to e
Deficit sialylation of vascular endothelium, circulating cells and macromolecules has been associated with the development of atherosclerosis. On the other hand, an elevated serum level of sialic acid is a long-lasting marker of atherosclerosis and complications from atherosclerosis. One may speculate that the inverse associations with atherosclerosis risk are due to some common underlying cause.
Aqueous aerosols produced by nebulizers used in clinical situations can rapidly change size as the patient inhales. This is caused by air with a relative humidity (RH) lower than inside the nebulizer being entrained and mixed with nebulized aerosol during the inhalation maneuver. A way to assess the change in size is to measure the aerosol in a test method that reflects the clinical situation. The
Popular Abstract in Swedish Diabetes är en kronisk ämnesomsättningsrubbning, med en förhöjd nivå av cirkulerande blodsocker som ett av dess första kännetecken. Sjukdomen bygger på det faktum att kroppens olika celler är beroende av hormonet insulin för att kunna ta emot och tillgodogöra sig det näringsgivande sockret glukos. Således, för att kunna bibehålla en normal blodsockernivå krävs två förutIn view of unsolved issues regarding cellular events underlying the adaptation of insulin secretion to insulin resistance, together with the observation that insulin secretion induced by the gastrointestinal hormone and neuropeptide cholecystokinin (CCK) is not solely explained by phospholipase C-protein kinase C (PLC-PKC) pathway activation, this study aimed at delineate mechanisms responsible fo
Popular AbstractJordbruksmarken representerar i det beskogade boreala landskapet en aktiv åtgärd som håller skogstillväxten borta. I avhandlingen undersöks lantbrukares praktiska beslutsfattande i samband med den öppna marken på gårdar som i Sverige ofta består av både jordbruks- och skogsmark. Som teoretiska ramverk används begreppen tidrum, landskap, orientering och åtagande för att förstå lantbThe human-induced open land (cropland, pasture) in the predominantly forested boreal landscapes relies on arable land use; it thus represents an active intervention to hold back forest regrowth. The thesis investigates the practical management decisions by landholders on discrete farms, which in Sweden often comprise both forest and arable lands. The theoretical framework utilizes the concepts tim
Abstract in Uncoded languages Polazna točka ovog članka je rat koji je održan u sjeverozapadnoj Bosni i Hercegovini te posebno interpersonalna interpretacija nasilja i biografski utjecaj ratnog nasilja. Srpski vojnici i policajci ciljano su vršili nasilje nad civilnoim stanovništvom u sjeverozapadnoj Bosni. U svojoj namjeri da se Bošnjaci i Hrvati istjeraju s tog područja, srpski vojnici i policajThe starting point of this article is the war that took place in northwestern Bosnia and Herzegovina and more specifi cally interpersonal interpretations of violence and the biographical impact of war-time violence. Serbian soldiers and police targeted their use of violent force directly against the civilian populations in northwestern Bosnia. In their quest to expel Bosniacs and Croats from this
Aim. Calcium phosphate deposition in blood vessels is correlated to increased mortality risk. In this study, the formation of solid calcium phosphate in an in vitro solution mimicking the inorganic part of blood serum was studied. Methods. The precipitates formed were analyzed using several experimental techniques, including infrared spectroscopy, Raman spectroscopy, X-ray energy dispersive spectr
Ferrochelatase (EC 4.99.1.1) catalyzes the last reaction in the heme biosynthetic pathway. The enzyme was studied in the bacterium Bacillus subtilis, for which the ferrochelatase three-dimensional structure is known. Two conserved amino acid residues, S54 and Q63, were changed to alanine by site-directed mutagenesis in order to detect any function they might have. The effects of these changes were
BACKGROUND: Earlier studies have shown that physical exercise and a higher workload increase muscle strength and improve gait and balance at all ages for both sexes. Published studies have, so far, failed to investigate the functional performance of elderly individuals concerning their long-term physical activity and variables of daily living. OBJECTIVE: To compare elderly women who participate in
Mammalian leukotriene A4 (LTA4) hydrolase is a bifunctional zinc metalloenzyme possessing an Arg/Ala aminopeptidase and an epoxide hydrolase activity, which converts LTA4 into the chemoattractant LTB4. We have previously cloned an LTA4 hydrolase from Saccharomyces cerevisiae with a primitive epoxide hydrolase activity and a Leu aminopeptidase activity, which is stimulated by LTA4. Here we used a m
Both benign and malignant prostate diseases elevate total prostate-specific antigen (tPSA), and the incidence of benign disease increases markedly with age. There is evidence, however, that free-to-total PSA ratio (%fPSA) and human kallikrein 2 (hK2) more closely reflect the malignant process. We tested the hypothesis that tPSA levels are more strongly predictive of cancer in younger when compared
Intragranular porosity and liquid saturation were influenced by the impeller speed, the loss-on-drying of starch, the added amount of water and the drug concentration. A reduction of the impeller speed and the drug concentration decreased the porosity and increased the liquid saturation. Response surface contours were plotted.
The purpose of this study was to investigate the validity of the Irena Daily Activity (IDA) assessment which measures occupational performance in adults with developmental disabilities. The instrument's content validity was investigated by elucidating its general appropriateness, its clinical applicability and the feasibility of the measurement procedure. Data were collected from a multidisciplina
