Glucagon- like peptide-1 ( GLP-1) plays a significant role in glucose homeostasis through its incretin effect on insulin secretion. However, GLP-1 also exhibits extrapancreatic actions, and in particular its possible influences on insulin sensitivity are controversial. To study the dynamic action of GLP-1 on insulin sensitivity, we applied advanced statistical modeling methods to study glucose dis
Asthma-like symptoms and bronchial hyper-responsiveness (BHR) to methacholine are prevalent in competitive cross-country skiers. Whether these symptoms (ski asthma) in these athletes are caused by asthma remains uncertain. Bronchial responsiveness to adenosine 5'-monophosphate (AMP) and nitric oxide (NO) concentration in exhaled air, both indirect markers of asthmatic airway inflammation, were inv
1. The glucose and ATP dependence of exocytosis were investigated in single mouse pancreatic B-cells by monitoring changes in cell capacitance evoked by voltage-clamp depolarizations, infusion of high [Ca2+]i buffers or photorelease of caged Ca2+ or ATP. 2. In intact B-cells, using the perforated patch whole-cell technique, glucose (5 mM) increased exocytotic responses evoked by membrane depolariz
A method for the in situ modification of hollow fiber membranes used as sampling units for microdialysis probes is presented. The method consists of adsorption-coating, high-molecular-weight poly(ethylene imine), PEI, onto membranes, already fitted on microdialysis probes. Modification of membranes was designed to specifically explore the so-called Andrade effects and thus enhance the interaction
The repressor activator protein 1 (RAP1) plays a role in telomere structure and function inS. cerevisiae. Here, the RAP1 homologue was identified and cloned from the budding yeast Saccharomyces castellii (scasRAP1). The scasRAP1 gene encodes a protein of 826 amino acids and shares an overall high degree of similarity with the S. cerevisiae RAP1 (scerRAP1). We demonstrate that the scasRAP1 is able
In a long-term and global perspective irrigated and terraced landscapes, landesque capital, have often been assumed to be closely associated with hierarchical political systems. However, research is accumulating that shows how kinship-based societies (including small chiefdoms) have also been responsible for constructing landesque capital without population pressure. We examine the political econo
OBJECTIVE: To investigate patients with cystic enhancing lesions on CT and to determine whether thallium-201 (201Tl) SPECT adds to further preoperative information in differential diagnosis between gliomas and abscesses. METHODS: Twenty one patients with cystic ring enhancing CT findings were studied and uptake indices were compared with CT enhancement volumes, histopathology, and survival times.

The emergence of Housing First in Sweden is described and analysed in the light of the deregulation of the housing market and the existing organisation of service delivery for homeless people. The spread and growth of Housing First in Sweden was promoted by Lund University during 2009. Although widely disseminated, implementation of Housing First has been slow. Only seven of Sweden’s 290 municipal
Purpose: Recently, there has been a growing interest in operating medical linear accelerators without a flattening filter Due to reduced scatter, leaf transmission and radiation head leakage a reduction of out-of-field dose is expected for flattening filter free beams. The aim of the present study was to determine the impact of unflattened beams on peripheral dose for advanced treatment techniques
Patients undergoing cardiac operations often require transfusions of red blood cells, plasma, and platelets. From a statistical point of view, there is a significant collinearity between the components, but they differ in indications for use and composition. This study explores the relationship between the transfusion of different blood components and long-term mortality in patients undergoing aor
In 2005, methylisothiazolinone (MI) on its own came into use as a preservative. Prior to that, MI was always present together with methylchloroisothiazolinone (MCI). Can the pattern of reactivity to the separate active ingredients in allergic patients tell us something about the primary sensitizer?
Objectives: Based on the integration of attachment and physical self-perception perspectives, the present study examined links between adolescents' engagement in physical activity and their attachment relationships with mothers, fathers, and friends, respectively, and assessed the potential mediation role of physical self-perception in this link. Design and methods: Using a cross-sectional design,
Parkinson's disease (PD) is a neurodegenerative disorder characterized by a progressive loss of nigral dopaminergic neurons and by the presence of aggregates containing α-synuclein called Lewy bodies. Viral vector-induced overexpression of α-synuclein in dopaminergic neurons represents a model of PD which recapitulates disease progression better than commonly used neurotoxin models. Previous studi
We describe an 85-year old male who was admitted to the hospital with acute coronary symptoms. Bedside echocardiography revealed a structure in the aortic root, and a computed tomography scan verified the diagnosis of an aneurysm in the sinus of Valsalva below the left coronary ostium. A coronary angiography also depicted the aneurysm clearly and clearly showed how the aneurysm compressed and disl
The return sludge of one of the four treatment lines at oresundsverket WWTP in Sweden was subjected to ozonation in full-scale to reduce filamentous bulking sludge. The biological nitrogen and phosphorus removal capacity along with effluent parameters were studied throughout the trial. Samples were also taken to track possible changes in microbial population due to ozone. 2.8-5.0 g O-3 kg(-1) trea
Steric stabilization of colloids forms a robust mechanism to obtain colloids that are stable in a variety of environments, and that can be used to study the phase behavior of hard or soft spheres. We report the synthesis of sterically stabilized colloids in an aqueous environment using readily dissolvable surfactants, with an unsaturated hydrophobic tail. We synthesized a new surfactant by esterif
Previous work implicated the complement system in adult neurogenesis as well as elimination of synapses in the developing and injured CNS. In the present study, we used mice lacking the third complement component (C3) to elucidate the role the complement system plays in hippocampus-dependent learning and synaptic function. We found that the constitutive absence of C3 is associated with enhanced pl
