Baseline prostate-specific antigen measurements and subsequent prostate cancer risk in the Danish Diet, Cancer and Health cohort

Aim: Although prostate-specific antigen (PSA) screening reduces mortality from prostate cancer, substantial over-diagnosis and subsequent overtreatment are concerns. Early screening of men for PSA may serve to stratify the male population by risk of future clinical prostate cancer. Methods and material: Case-control study nested within the Danish 'Diet, Cancer and Health' cohort of 27,179 men aged

Thermomyces lanuginosus lipase-catalyzed hydrolysis of the lipid cubic liquid crystalline nanoparticles.

In this study well-ordered glycerol monooleate (GMO)-based cubic liquid crystalline nanoparticles (LCNPs) have been used as substrates for Thermomyces lanuginosus lipase in order to establish the relation between the catalytic activity, measured by pH-stat titration, and the change in morphology and nanostructure determined by cryogenic transmission electron microscopy and synchrotron small angle

Hypertension in the Elderly: What Is the Goal Blood Pressure Target and How Can This Be Attained?

For the aging populations of Europe, many emerging health problems in addition to myocardial infarction and stroke are associated with hypertension. Recently, the role of hypertension in the risk of vascular cognitive impairment and dementia has been highlighted, and there are studies to show that control of hypertension may slow this process. Furthermore, as many elderly individuals will also dev

III-V Nanowire Synthesis by Use of Electrodeposited Gold Particles.

Semiconductor nanowires are great candidates for building novel electronic devices. Considering the cost of fabricating such devices, substrate reuse and gold consumption are the main concerns. Here we report on implementation of high throughput gold electrodeposition for selective deposition of metal seed particles in arrays defined by lithography for nanowire synthesis. By use of this method, a

A cathodoluminescence study of the influence of the seed particle preparation method on the optical properties of GaAs nanowires.

Cathodoluminescence at 8 K is used to compare the optical properties of AlGaAs-capped GaAs nanowires, grown by metal-organic vapour phase epitaxy and seeded by gold particles prepared by different methods. Six different methods were used to fabricate and deposit gold seed particles onto GaAs substrates: colloid particles, aerosol particles and particles defined by electron beam lithography. The na

Nanoscale Energy Converters

An overview is given of the types of energy converters considered by this symposium: systems that make use of nanoscale phenomena and nanotechnology to achieve higher conversion efficiency, to achieve qualitatively enhanced performance, or to access new energy resources. The focus is on general concepts and principles, and approaches used by several nanoscale energy converters are identified.

Evolution of disease burden over five years in a multicenter inception systemic lupus erythematosus cohort

Objective We describe disease activity, damage, and the accrual of key autoantibodies in an inception systemic lupus erythematosus (SLE) cohort. Methods. The Systemic Lupus International Collaborating Clinics (SLICC) International Research Network, comprising 27 centers from 11 countries, has followed an inception cohort of SLE patients yearly according to a standardized protocol. Of these patient

Comparison of Stroke Mortality in Finnish-Born Migrants Living in Sweden 1970-1999 and in Swedish-Born Individuals

A limited number of studies have been found on stroke mortality in migrants showing higher mortality for some groups. Influence of time of residence has been studied by one research group. An earlier study showed a significantly higher number of deaths in Diseases of the circulatory system in Finnish migrants compared with native Swedes. To test the hypothesis of a higher mortality in and a decrea

Gate-Defined Quantum Devices Realized in InGaAs/InP by Incorporating a High-kappa Layer as Gate Dielectric

Single and double quantum dot devices are realized in InGaAs/InP heterostructures by top gating technology with incorporated High-kappa HfO2 gate dielectric layers. At 300 mK, Coulomb blockade effects are observed in as-fabricated devices, and the charge states can be measured by the integrated quantum point contacts. The developed technology should stimulate the research on quantum devices made f

Cancer incidence and mortality in Swedish sterilant workers exposed to ethylene oxide: updated cohort study findings 1972-2006.

OBJECTIVES: To assess whether cancer incidence, mainly from lymphohaematopoietic tumours and breast cancer, and mortality were increased in a cohort of Swedish sterilant workers exposed to low levels of ethylene oxide (EtO), updated with 16 more years of follow up. METHODS: The mortality and cancer incidence 1972-2006 experienced by a cohort of 2,171 male and female workers employed for at least

Impact of Atomic Oxygen on the Structure of Graphene Formed on Ir(111) and Pt(111)

The effect of atomic oxygen adsorption on the structure and electronic properties of monolayer graphite (MG or graphene) grown on Pt(111) and Ir(111) has been studied using X-ray photoelectron spectroscopy, near-edge X-ray absorption fine structure spectroscopy, and scanning tunneling microscopy. For comparison, the adsorption of atomic oxygen on highly oriented pyrolytic graphite has been studied

75% success rate after open debridement, exchange of tibial insert, and antibiotics in knee prosthetic joint infections.

Background and purpose - Prosthetic joint infection (PJI) is a leading cause of early revision after total knee arthroplasty (TKA). Open debridement with exchange of tibial insert allows treatment of infection with retention of fixed components. We investigated the success rate of this procedure in the treatment of knee PJIs in a nationwide material, and determined whether the results were affecte

Variety in vegetable and fruit consumption and risk of bladder cancer in the European Prospective Investigation into Cancer and Nutrition

Recent research does not show an association between fruit and vegetable consumption and bladder cancer risk. None of these studies investigated variety in fruit and vegetable consumption, which may capture different aspects of consumption. We investigated whether a varied consumption of vegetables and fruits is associated with bladder cancer risk in the European Prospective Investigation into Can

Size- and shape-dependent phase diagram of In-Sb nano-alloys

Nano-scale alloy systems with at least one dimension below 100 nm have different phase stabilities than those observed in the macro-scale systems due to a large surface to volume ratio. We have used the semi-empirical thermodynamic modelling, i.e. the CALPHAD method, to predict the phase equilibria of the In-Sb nano-scale systems as a function of size and shape. To calculate the size- and shape-de

Combining functional features of whole-grain barley and legumes for dietary reduction of cardiometabolic risk: a randomised cross-over intervention in mature women.

The usefulness of dietary strategies against cardiometabolic risk is increasingly being acknowledged. Legumes and whole grains can modulate risk markers associated with cardiometabolic diseases, but their possible additive/synergistic actions are unknown. The objective of the present study was to assess, in healthy subjects, the effect of a diet including specific whole-grain barley products and l

Reproductive risk factors and endometrial cancer: the European Prospective Investigation into Cancer and Nutrition

Endometrial cancer risk has been associated with reproductive factors (age at menarche, age at menopause, parity, age at first and last birth, time since last birth and use of oral contraceptives (OCs)]. However, these factors are closely interrelated and whether they act independently still requires clarification. We conducted a study to examine the association of menstrual and reproductive varia
