Kinins are potent pro-inflammatory peptides that act through two G protein-coupled receptor subtypes, B1 (B1R) and B2 (B2R). Kinin-stimulated B2R signaling is often transient, whereas B1R signaling is sustained. This was confirmed by monitoring agonist-stimulated intracellular Ca(2+) mobilization in A10 smooth muscle cells expressing human wild-type B2R and B1R. We further studied the role of rece
Ribonucleotide reductase (RNR) is the only source for de novo production of the four deoxyribonucleoside triphosphate (dNTP) building blocks needed for DNA synthesis and repair. It is crucial that these dNTP pools are carefully balanced, since mutation rates increase when dNTP levels are either unbalanced or elevated. RNR is the major player in this homeostasis, and with its four different substra
Background: The utility of conventional prostate-specifi c antigen (PSA) measurements in blood for monitoring rapid responses to treatment for prostate cancer is limited because of its slow elimination rate. Prior studies have shown that free PSA (fPSA), intact PSA (iPSA) and human kallikrein-related peptidase 2 (hK2) are eliminated more rapidly after radical prostatectomy. In contrast, all three
We have analyzed the content of N-unsubstituted glucosamine in heparan sulfate from glypican-1 synthesized by endothelial cells during inhibition of (a) intracellular progression by brefeldin A, (b) heparan sulfate degradation by suramin, and/or (c) endogenous nitrite formation. Glypican-1 from brefeldin A-treated cells carried heparan sulfate chains that were extensively degraded by nitrous acid
BACKGROUND: Job strain, defined as high job demands and low job control, has not previously been explored as a possible determinant of male fertility. We collected prospective data on job strain among men, and describe the associations with semen quality and probability of conceiving a clinical pregnancy during a menstrual cycle. METHODS: Danish couples (N = 399) who were trying to become pregnant
A kinetic model of the fermentative production of lactic acid from glucose by Lactococcus lactis ssp. lactis ATCC 19435 in whole-wheat flour has been developed. The model consists of terms for substrate and product inhibition as well as for the influence of pH and temperature. Experimental data from fermentation experiments under different physical conditions were used to fit and verify the model.
Popular Abstract in Swedish Hur löser den intellektuelle politikern problem och hur skapas kontakten med den politiska omgivningen? Svaren på frågorna skall kortfattat presenteras och är intressanta för politiker, partier, väljare och forskare. Svaren visar nämligen hur intellektuella politiker under kristider producerar och presenterar innovativa lösningar som kan få stor betydelse för samhällsutA new theory on the intellectual politician, which has the ability to produce a designed type of problem-solving, has been developed from political science theory, cognitive theory as well as art theory. A cognitive concept, modified integrative complexity, consisting of four sub-concepts, frame reflection, differentiation, reframing and integration has been developed. The relation between politic
Globular and fibrous proteins are compared with regard to structural behaviour on heating, where the former expands and the latter contracts. The meat protein composition and structure is briefly described. The behaviour of the different meat proteins on heating is discussed. Most of the sarcoplasmic proteins aggregate between 40 and 60 ° C, but for some of them the coagulation can extend
An integrative vector was constructed to allow expression of heterologous proteins into the adhB locus of Zymomonas mobilis. As a reporter gene, the ORF of a bright variant of green fluorescent protein from Aequorea victoria (GFPuv) was fused to the adhB strong promoter from Z. mobilis by using a two-step PCR strategy. Z. mobilis recombinant strains that were stably marked by precise gene replacem
Popular Abstract in English The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing domain whereas both PDH and
Popular Abstract in Swedish Typ 2 diabetes är en av världens vanligaste och snabbast ökande kroniska sjukdomar. Sjukdomen är smygande och ger ofta inledningsvis inte några särskilda symptom. Den kan därigenom förbli oupptäckt under många år. Typ 2 diabetes är dock en allvarlig sjukdom; överdödligheten i hjärt-kärlsjukdomar är fyra gånger högre hos patienter med typ 2 diabetes än hos dem som inte hTo examine cardiovascular risk factors, glycaemic control and survival in patients with type 2 diabetes mellitus (T2DM) treated in primary care, patients with T2DM and a randomised age-stratified sample of men and women aged ≥40 years living in the same community were surveyed 1992-1994. ß–Cell function and insulin resistance were estimated using the Homeostasis Model Assessment (HOMA). Vital stat
Fabrication and characterisation of buried metal contacts in compound semiconductors are demonstrated. The contacts have been investigated due to their usage both as gates in transistors and as active or passive elements in novel devices. A detailed description of the processing conditions for fabrication of nm-sized W-structures in a lift-off process is given. These structures have been embedded
The traditional orthosis are tight and allow minimal evaporation. A new prototype was designed. The thermal foot model tests were carried out at isothermal (Ts=Ta=34 °C) and non-isothermal (Ta=23 °C) conditions with relative humidity set to 17 and 41 %, respectively, and at air velocities of 0.25 (LVa) and 0.85 m/s (HVa). Evaporative resistance (Ret) was calculated based on foot model’s heat loss
Popular Abstract in Swedish Hos järnvägsfordon ger den låga friktionen mellan hjul och räls upphov till långa bromssträckor, i allmänhet längre än lokförarens siktsträcka. Om föraren påbörjar en inbromsning först när han ser ett hinder på spåret kan det vara för sent. Säker järnvägstrafik kan därför inte enbart lita till föraren, utan det måste också finns ett överordnat signalsystem, ofta i kombiIn railway traffic the low friction between wheel and rail causes long braking distances, normally much longer than the sight distance of the driver, i.e. if the driver starts the braking when a problem on the track is discovered, it might be too late to brake the train. Therefore, safe railway traffic can not only rely on the driver. It is necessary to have a signalling or even an automatic surve
Popular Abstract in Swedish Denna rapport behandlar trafiklaster på broar och de lasteffekter som de ger upphov till. Böjmoment och tvärkraft för olika brotyper beskrivs i form av statistiska fördelningar med tillhörande parametrar. Dessa är baserade på mätningar av verklig trafik gjorda i Sverige under åren 2002-2003 i Vägverkets regi. Resultaten finns redovisade i Vägverket (2004b), och finns laThis thesis treats traffic load effects in road bridges and in particular bending moment and shear force in different types of bridges. All traffic load effects are described in terms of statistical distribution functions for annual extreme values. The statistical distributions are based on measurements of real traffic, made in Sweden during 2002-2003. The measurements are managed by the Swedish R
To gain insight into the mechanisms responsible for the loss of the glucagon response to insulin-induced hypoglycemia in type 1 diabetes, glucagon responses to 4 different stimuli were examined over 3 months of diabetes in alloxan-treated mice. At 1, 6, and 12 weeks after alloxan (60 mg/kg), phloridzin (0.1 g/kg) was administered to overnight fasted diabetic mice to match the glucose levels of tho

Aims The aim was to investigate the influence of LE muscle strength on traumatic knee injury in youth female and male athletes. Methods 225 athletes (40% females) from sport senior high schools in Sweden were included in this case-control study. The athletes record
