The functional implication of previously shown effects on pial wall morphology by sympathectomy was tested. Following either ganglionic or pre-ganglionic denervation in 1-week-old rats the passive arterial compliance was reduced in basal cerebral arteries of 20-week-old normotensive, but not of hypertensive animals. The magnitude of the denervation induced stiffness was similar to the alteration s

The proposed experiments for the first RISING (Rare ISotope INvestigations at GSI) campaign will exploit secondary unstable beams at relativistic energies in the range from 100 MeV/u to 400 MeV/u. The RISING spectrometer will be employed for relativistic Coulomb excitation and for high-resolution gamma-spectroscopy experiments after secondary nucleon removal reactions and secondary fragmentation.

Active Photosystem II (PS II) cores were prepared from spinach, pea, Synechocystis PCC 6803, and Thermosynechococcus vulcanus, the latter of which has been structurally determined [Kamiya and Shen (2003) Proc Natl Acad Sci USA 100: 98-103]. Electrochromic shifts resulting from Q(A) reduction by 1.7-K illumination were recorded, and the Q(x) and Q(y) absorption bands of the redox-active pheophytin

Twenty parents of boys (ages 2-14 years) hospitalized for hypospadias repair in a pediatric surgery department in Sweden, were interviewed concerning their experience when their child was hospitalized. A qualitative analysis of the interviews indicated that the most important issue to the parents was finding security at the hospital. Parents manifested one of three different strategies that enable

Reduced capacity to produce ROS increases the severity of T cell-dependent arthritis in both mice and rats with polymorphisms in neutrophil cytosolic factor 1 (Ncf1) (p47phox). Since T cells cannot exert oxidative burst, we hypothesized that T cell responsiveness is downregulated by ROS produced by APCs. Macrophages have the highest burst capacity among APCs, so to study the effect of macrophage R

The formation of micro-droplets due to a pulsative micro-jet (width of 40 mu m) is studied using the 3D Navier-Stokes equations for multi-phase flows using the Volume of Fluid (VOF) and Volume of Solid (VOS) models. The droplet formation is studied for different transient velocity conditions and mass rates. The numerical results show reasonable agreement with both analytical theory and experimenta

Rapid improvement of glucose control in diabetics may cause a transient progression of ischemic retinopathy. We report a transient bilateral acute asymptomatic optic disc swelling associated with rapid improvement of metabolic control in a male Type I diabetic. It is d, suggested that the optic disc swelling could be caused n of by a rapid near-normal normalization of the blood glucose.

Software is an increasing and important part of many products and systems. Software, hardware, and system level components have been developed and produced following separate processes. However, in order to improve the quality of the final complex product, requirements and prospects for an automatic integrated process support are called for. Product data management (PDM) has focused on hardware pr

While other companies have a hard time reaching out to universities, leading university reach into Porsche to make substantial contributions to Porsche's innovation leadership. This is why and how Porsche manages to leverage university research in this unique way.

Aims Tumour necrosis factor-alpha (TNF-alpha) is a proinflammatory cytokine, which is implicated in some metabolic disorders and may play a role in the development of cardiovascular disease. We examined whether plasma TNF-alpha is related to established cardiovascular risk indicators, plasma levels of soluble cellular adhesion molecules and carotid artery intima-media thickness determined by ultra

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Introduktion Adrenokortikotropiskt hormon (ACTH) stimulerar frisättningen av steroid¬hormoner, främst kortisol, från binjurarna. Kortisol är livsnödvändigt och finns alltid i blodet och förhöjs kraftigt vid stress. I början av 90-talet fann vår forskningsgrupp en koppling mellan ACTH och fettomsättningen som inte involverade steroidhAbstract Adrenocorticotrophic hormone (ACTH) has strong and direct lipid-lowering effects in man. All apoB-containing lipoproteins, i.e. VLDL, LDL, Lp(a), are reduced by 25-30%. In contrast, levels of HDL increase about 10%. In hepatic cell cultures, ACTH inhibits expression and secretion of apoB. In this thesis we corroborate that the reduced apoB synthesis, seen in hepatic cell systems, is als

In this paper, we present and compare the two different XUV interferometric techniques using high-order harmonics that have been developed so far. The first scheme is based on the interference between two spatially separated phase-locked harmonic sources while the second uses two temporally separated harmonic sources. These techniques have been applied to plasma diagnostics in feasibility experime

Stable carbon isotope analysis of terrestrial plant leaves preserved in Quaternary lake sediments has the potential to provide high-resolution reconstructions of past climatic conditions. Preferably, delta(13)C measurements should be made on a single leaf component, e.g. cellulose, but this approach is often precluded by limited leaf availability. Previous work suggests that reliable palaeoclimati

Salt-containing membranes based on polymethacrylates having poly(ethylene carbonate-co-ethylene oxide) side chains, as well as their blends with poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), have been studied. Self-supportive ion conductive membranes were prepared by casting films of methacrylate functional poly(ethylene carbonate-co-ethylene oxide) macromonomers containing lithium

We prove a uniqueness result for autonomous divergence-free systems of ODE's in the plane and give an application to the study of water flows with vorticity.
