Increased urinary albumin excretion rate (AER), microalbuminuria, has been regarded as a sign of incipient nephropathy. The influence of exercise on AER was investigated in 10 male type I diabetics and in 12 age-matched male controls. The duration of diabetes was 7-31 years (median 14 years). The exercise tests were performed both as a combined submaximal workload-waterload test and as a maximal w

Photoemission studies and layer resolved Korringa-Kohn-Rostoker (KKR) multiple scattering calculations are used to find the assignment of the surface core-level shifts to the top layers of the Be(10 (1) over bar0) surface. Striking similarities between experimental and calculated data make it possible to assign the largest shift to layer two, the second largest shift to layers three and four, and

Popular Abstract in Swedish Ett kärnkraftverk är utrustat med ett omfattande försvar avsett att förhindra radioaktivt utsläpp vid en eventuell reaktorolycka. Detta försvar är uppbyggt av ett antal skyddsbarriärer, där reaktorinneslutningen utgör den sista barriären mot omgivningen. Inneslutningens primära uppgift är att motstå det inre övertryck som kan förväntas vid en reaktorolycka. Alla svenskaA nuclear power plant is provided with an extensive defense intended to prevent radioactive discharge in case of a reactor accident. This defense is built up of several independent safety barriers, where the reactor containment constitutes the last barrier to the environment. The fundamental safety function of the containment is to withstand the internal pressure expected in the event of an accide

Objective: To develop a simple, easily administered pencil-and-paper questionnaire to determine the degree to which behavioral patterns play a role in smoking dependence. Methods: A modified Delphi technique was used to identify initial questions and to eliminate obvious duplications. Phase 2 utilized multiple statistical methods (principal components analysis, cluster analysis, stepwise multiple

Popular Abstract in Swedish Forskning och studier av ytvattensystem i sudanesiska röda havsområdet för utveckling av relevant metodik medför ett antal konceptuella svårigheter. Ett huvudsakligt problem är den begränsade tillgången till litteratur och mätdata för modellutveckling. En annan svårighet är tillämpligheten av redan existerande metoder och modeller utvecklade i andra regioner. För att bThe magnitude and availability of surface waters in the arid/semi-arid Sudanese Red Sea region has been examined. In conjunction with the research objective, opinions and methodologies applied by previous researchers have been assessed. The study applied a geographical hydrological synthesis within a GIS framework. As a system with advanced geo-modelling capabilities, GIS is used to integrate spat

1. Extracellular adenosine triphosphate (ATP) is mitogenic for vascular smooth muscle cells (VSMC) and stimulates several events that are important for cell proliferation: DNA synthesis, protein synthesis, increase of cell number, immediate early genes, cell-cycle progression, and tyrosine phosphorylation. 2. Receptor characterization indicates mitogenic effects of both P2U and P2Y receptors. The

We consider the semi-linear elliptic equation Delta u + f (x, u) + g (vertical bar x vertical bar)x center dot del u = 0, in some exterior region of R-n, n >= 3. It is shown that if f depends radially on its first argument and is nonincreasing in its second, boundary conditions force the unique solution to be radial. Under different conditions, we prove the existence of a positive radial asymptoti

The interruption in deposition during the K/T transition in the Parnassus-Ghiona Zone caused the formation of hardgrounds and intraformational conglomerates in the central parts. During the later part of the early Paleocene to the middle or early part of the late Paleocene a shallow sea covered central Parnassus; stromatolites formed in broad valleys and phosphatic calcarenitic accumulations in sm

We report the temperature dependence of the Au-assisted growth of InAs nanowires in MOVPE. Extensive studies of the growth of such nanowires have attributed growth to the so-called vapor-liquid-solid (VLS) mechanism, with a liquid Au-In alloy particle. We assert here that growth is instead assisted by a solid particle and does not occur at all when the particle is a liquid. Thus the temperature ra

The tumor oxygenation status associates with aggressive behavior. Oxygen shortage, hypoxia, is a major driving force behind tumor vascularization, and hypoxia enhances mutational rate, metastatic spread, and resistance to radiation and chemotherapy. We recently discovered that hypoxia promotes dedifferentiation of neuroblastoma and breast carcinoma cells and development of stem cell-like features.

Popular Abstract in Swedish Traditionellt har olika aspekter av ett ekosystem studerats var för sig inom olika ekologiska discipliner såsom växtfysiologi, forskning om hur organismer interagerar med varandra och forskning om hur ekosystem som helhet beter sig. Denna avhandling innehåller exempel på att simulationsmodeller gör det möjligt att undersöka hur de olika processerna samverkar för att forPlant physiology, population dynamics and the structure and functioning of ecosystems are closely interrelated. However, these processes are often investigated independently within different subdisciplines of ecology. Mechanistic models of ecosystem structure and functioning combine representations of processes operating at a range of scales and levels of organisation, providing a tool for the des

Secretory lysosomes of natural killer (NK) cells combine storage, regulated secretion and lysosomal activity. We asked whether one could target exogenous proteins to the secretory lysosomes of NK-cells for final delivery into a tumor site upon degranulation. cDNAs for both soluble and transmembrane (tm) proteins were expressed in the human YT-Indy NK-cell line. Targeting of a soluble TNF receptor

An enzyme has been isolated from human liver by DEAE-cellulose chromatography and has been shown by competitive substrate inhibition to be capable of hydrolysing synthetic beta-D-galactosides, beta-D-glucosides, beta-D-fucosides, beta-D-xylosides, and alpha-L-arabinosides. Another form of alpha-L-arabinosidase activity elutes with the major beta-D-galactosidase component on DEAE-chromatography, bu

In this prospective study, the overall treatment and outcome of patients that underwent major lower limb amputation in a defined population is described. The study was performed over a five year period in the Health Care District of North-East Skåne, Sweden. Some 190 patients, permanent inhabitants of the Health Care District, underwent major lower limb amputation. Sixteen (16) of these patients h
