Glucagon like peptide 1 (GLP-1) is an incretin hormone released as a bioactive peptide from intestinal L-cells in response to eating. It acts on target cells and exerts several functions as stimulating insulin and inhibiting glucagon. It is quickly deactivated by the serine protease dipeptidyl peptidase IV (DPP-IV) as an important regulatory mechanism. GLP-1 analogues are used as antidiabetic drug
Northern hemisphere peatlands play an important role in the global carbon (C) cycle, accounting for about 30% of global soil C and similar to 10-25% of global natural methane (CH4) emissions. Satellite remote sensing has the potential for extracting continuous information related to C exchange rates at regional and global extents, yet, few studies have focused on peatlands. In this study we examin
Popular Abstract in Swedish Normal hjärnaktivitet är beroende på en delikat balans mellan inhibitorisk och excitatorisk nervcellssignallering. Om denna balans störs och lutar mer åt en ökad excitering uppstår epileptiska anfall. Ungefär 1 % av befolkningen i västvärldens drabbas av epilepsi, framförallt av temporallobs-epilepsi (TLE) vilket är den vanligast förekommande formen av epilepsi bland vuTemporal lobe epilepsy (TLE) is the most common form of epilepsy among adult patients, and the most problematic one as seizures cannot be controlled by currently available drugs in 30 % of patients. Gene therapy based on overexpression of endogenous anti-epileptic agents such as the neuropeptide galanin and the glial cell line-derived neurotrophic factor (GDNF) represents a promising new approach
Objective The aim of this study was to estimate the rate of fetal loss in dichorionic (DC) and monochorionic (MC) twin pregnancies stratified according to zygosity and method of conception. Methods In a prospective multicenter observational study women with a twin pregnancy bad an ultrasound scan before 14 + 6 weeks' gestation in order to determine chorionicity. The fetal loss rate, the perinatal,
This thesis covers the development of a silicon neural interface, with focus on silicon sieve electrode fabrication, design, nerve regeneration, signal recording and biocompatibility. A study of how the via hole size and transparency of the perforated sieve membrane influences the nerve regeneration is presented together with a study on soft tissue responses to planar and porous silicon. A method
Superporous agarose beads contain two sets of pores, diffusion pores and so-called superpores or flow pores, in which the chromatographic flow can transport substances to the interior of each individual bead [Gustavsson and Larsson, J. Chromatogr. A 734 (1996) 231]. The existence of pore flow may be proven indirectly by the chromatographic performance of beads but it has never been directly demons
Phosphodiesterase type 3B (PDE3B) has been shown to be activated and phosphorylated in response to insulin and hormones that increase cAMP. In order to study serine/threonine protein phosphatases involved in the regulation of rat adipocyte PDE3B, we investigated the phosphorylation and activation of PDE3B in vivo in response to phosphatase inhibitors and the dephosphorylation and deactivation of P
Objective. To study degree of blood pressure (BP) control in primary healthcare (PHC) treated hypertensive patients in relation to sex, age, drug treatment, and concomitant diseases. Design. Random sample of patients with hypertension. Setting. Ten PHC centres in the Region of Skane, Sweden. Subjects. All the 30- to 95-year-old patients with hypertension who during the period 12 September to 24 Se
Interaction of mono- and disaccharides, polysaccharide particles and yeast cells with boronate-containing copolymers (BCC) of N-acryloyl-m-aminophenylboronic acid (NAAPBA) with NN-dimethylacrylamide (DMAA) or N-isopropylacrylamide (NIPAM) was studied. The binding of saccharides to BCC of NIPAM resulted in a shift of its phase transition temperature (Delta T-p), which provided a quantitative measur
BACKGROUND AND AIMS: Leukocyte recruitment is a key feature in ischemia-reperfusion (I/R)-induced tissue injury. The aim of the present study was to investigate the effect of Rho-kinase inhibition on I/R-provoked leukocyte recruitment in the colon. METHODS: C57BL/6 mice were subjected to 30 min of ischemia by clamping of the superior mesenteric artery followed by 120 min of reperfusion. Intraperit
Secondary metabolites produced by fungi and bacteria are among the potential agents that contribute to adverse health effects observed in occupants of buildings affected by moisture damage, dampness and associated microbial growth. However, few attempts have been made to assess the occurrence of these compounds in relation to moisture damage and dampness in buildings. This study conducted in the c
Ultrasound optical tomography enables noninvasive characterization of tissue and lesions up to 5 cm below the skin surface, by enhancing diffuse optical tomography with ultrasound focusing resolution and an increased number of measurement points. For optimal clinical imaging, it is essential to be able to reconstruct tissue optical properties in real time during in vivo measurements, and therefore
UNLABELLED: Children with congenital and acquired heart disease have an increased risk of thromboembolic events. There is a paucity of evidence on the optimal approach to thromboprophylaxis for this population, and the introduction of direct oral anticoagulants in recent years has led to significant variation in clinical practice. The aim of the study was to describe current practice in thrombopro

Background In mild asthma exercise-induced bronchoconstriction (EIB) is usually treated with inhaled short-acting beta(2) agonists (SABAs) on demand. Objective The hypothesis was that a combination of budesonide and formoterol on demand diminishes EIB equally to regular inhalation of budesonide and is more effective than terbutaline inhaled on demand. Methods Sixty-six patients with asthma (>12 ye
Abstract The ozone (O3) decomposition in the pre-heat zone of flames can initiate and accelerate the chain-branching reactions. In the present study, formaldehyde (CH2O) was investigated by both experiment and simulation methods in methane/air laminar premixed flames under atmospheric conditions. The formaldehyde concentration profiles in the flames were measured with CH2O-PLIF. When 4500 ppm of o
Identification and isolation of cardiomyocytes from the heart, embryonic stem cells, or induced pluripotent stem cells is a challenging task and will require specific isolation techniques. Less than 30% of the cells within the murine heart are cardiomyocytes and, what is more, there are multiple sub-populations of cardiomyocytes like atrial, ventricular and conduction system cardiomyocytes. In Pap
Background: The presence of echolucent carotid plaques as defined by low ultrasound grey-scale median (GSM) is associated with a higher risk of stroke and myocardial infarction. Betablockers have shown possible anti-atherosclerotic effects. The aim of the present study was to determine if there is an association between carotid plaque GSM and treatment with betablockers. Methods: The GSM of the ca
OBJECTIVE: To study the association of physician's sex with blood pressure, lipid control, and cardiovascular risk factors in treated hypertensive men and women, stratified for the sex of their physician. METHODS: In a cross-sectional survey of hypertensive patients, 264 primary care physicians (PCPs), 187 men and 77 women from across Sweden, recruited 6537 treated hypertensive patients (48% men)
