Flux-periodic oscillations in proximitized core-shell nanowires.

Flux-periodic oscillations of the superconducting gap in proximitized core-shell nanowires are explored. Periodicity of oscillations in the energy spectrum of a cylindrical nanowire is compared with nanowires having hexagonal and square cross-section geometry, along with the effects of Zeeman and Rashba spin-orbit interaction. A transition between/and/2periodicity is found and shown to be dependent on the chemical potential, with correspondence to degeneracy points of the angular momentum quantum number.

Effect of impurities on charge and heat transport in tubular nanowires.

We calculate the charge and heat currents carried by electrons, originating from a temperature gradient and a chemical potential difference between the two ends of tubular nanowires with different geometries of the cross-sectional areas: circular, square, triangular, and hexagonal. We consider nanowires based on InAs semiconductor material, and use the Landauer-Büttiker approach to calculate the transport quantities. We include impurities in the form of delta scatterers and compare their effect for different geometries.

We followed 151 patients from 1996 to 2007 to investigate if microalbuminuria is a risk factor in coronary heart disease. All patients admitted with acute myocardial infarction in 1996 were included.

Phenolic compounds in different barley varieties: identification by tandem mass spectrometry (QStar) and NMR; quantification by liquid chromatography triple quadrupole-linear ion trap mass spectrometry (Q-Trap).

Barley (Hordeum vulgare) is an important cereal that has many applications; as a human food, in malt products and as livestock feed. The content of soluble health-promoting fibers, beta-glucans, varies substantially among barley varieties. In the present study, the content of secondary metabolites with potential positive health effects in different high- and low-beta-glucan barley varieties was studied.

Microalbuminuria and obesity: impact on cardiovascular disease and mortality.

Objective: Microalbuminuria and obesity are both associated with cardiovascular disease (CVD). The aim of this study was to determine the association between obesity (measured by body mass index, waist-to-hip ratio, waist circumference) and different levels of microalbuminuria. We also aimed to determine the risk of death and CVD at different levels of microalbuminuria and obesity.

The association between metabolic syndrome, microalbuminuria and impaired renal function in the general population: impact on cardiovascular disease and mortality.

Objective: Microalbuminuria and metabolic syndrome are both associated with cardiovascular disease (CVD). The aim of this study was to determine the potential association between numbers of components in the metabolic syndrome, different levels of microalbuminuria and renal function. We also aimed to determine the risk of death and CVD at different levels of microalbuminuria and renal function and numbers of components in the metabolic syndrome.

Very low level of microalbuminuria is associated with increased risk of death in subjects with cardiovascular or cerebrovascular diseases.

Background: The original definition of microalbuminuria (20-200 microg min-1 or 15-150 microg min-1 overnight) is based on studies of patients with diabetes, in whom microalbuminuria was associated with increased risk of chronic renal failure. In a recent report an overnight urinary albumin excretion (UAE) above only 5 microg min-1 was strongly predictive of coronary heart disease and death in the general population. The aim of the present study was to investigate if this cut-off level also has prognostic value in a population with cardiovascular or cerebrovascular disease.

New definition of microalbuminuria in hypertensive subjects: association with incident coronary heart disease and death.

Microalbuminuria has so far been defined as urinary albumin excretion between 20 and 200 microg/min (or 15 to 150 microg/min overnight). In a recent report, an overnight urinary albumin excretion >5 microg/min was strongly predictive of coronary heart disease and death in the general population. The aim of the present study was to confirm this observation in a population of hypertensive individuals.

Development of aerobic power in pubescent male soccer players related to hematocrit, hemoglobin and maturation. A longitudinal study.

Aim: More than ever young athletes are training intensively and compete at high levels. As adolescent athletes are training in a period associated with many changes in growth and maturation longitudinal studies are important to elucidate the development in physical parameters. The aim of this study was to evaluate the development in aerobic power in elite as well as non-elite soccer players during the years of puberty and to relate it to maturation as well as hemoglobin and hematocrit.

Very low levels of microalbuminuria are associated with increased risk of coronary heart disease and death independently of renal function, hypertension, and diabetes.

Background: The aim of this study was to assess the level of urinary albumin excretion (microalbuminuria), which is associated with increased risk of coronary heart disease and death, in the population. Microalbuminuria has been suggested as an atherosclerotic risk factor. However, the lower cutoff level of urinary albumin excretion is unknown.

Affinity purification of recombinant protein-tyrosine phosphatase 1B using a highly selective inhibitor.

Our structure-based drug discovery program within the field of protein-tyrosine phosphatases (PTPs) demands delivery of significant amounts of protein with extraordinary purity specifications over prolonged time periods. Hence, replacement of classical, multi-step, low-yield protein purifications with efficient affinity techniques would be desirable. For this purpose, the highly selective PTP1B inhibitor 2-(oxalyl-amino)-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine-3-carboxylic acid (OTP) was coupled to epoxy-activated Sepharose 6B (OTP Sepharose) and used for one-step affinity purification of tag-free PTP1B.

Anaerobic power and muscle strength characteristics of 11 years old elite and non-elite boys and girls from gymnastics, team handball, tennis and swimming.

The aim of the present investigation was to study the possible effects of specificity of training on muscle strength and anaerobic power in children from different sports and at different performance levels in relation to growth and maturation status. Hundred and eighty-four children of both gender participating either in swimming, tennis, team handball or gymnastics were recruited from the best clubs in Denmark. Within each sport, the coach had divided the children into an elite (E) and non-elite (NE) group according to performance level and talent.
