InP core-shell nanowire pn-junctions doped with Zn and Sn have been investigated in terms of growth morphology and shell carrier concentration. The carrier concentrations were evaluated using spatially resolved Hall effect measurements and show improved homogeneity compared to previous investigations, attributed to the use of Sn as the n-type dopant. Anisotropies in the growth rate of different fa
ObjectiveTo examine the frequency and characteristics of headaches and their association with global disease activity and health-related quality of life (HRQOL) in patients with systemic lupus erythematosus (SLE). MethodsA disease inception cohort was assessed annually for headache (5 types) and 18 other neuropsychiatric (NP) events. Global disease activity scores (SLE Disease Activity Index 2000
BACKGROUND: Little focus has been paid to the role of mental health among young people with regard to risky sexual behavior and HIV prevention in sub-Saharan Africa. The aim of this study was to investigate the relationship between poor mental health and risky sexual behavior (HIV/AIDS) among a population of university students in Uganda. METHODS: In 2005, 980 Ugandan university students completed
To examine the association of sialic acid (SA) with first recorded diabetes mellitus-related hospitalization.
III-V narrow band gap nanowires are considered for device applications. Nanowires are grown using the vapor-liquid-solid growth mechanism with the aim to implement high-performance devices. It is shown that high quality InAs, InSb, and GaSb nanowires, as well as their alloys, may be grown by metal organic vapor phase epitaxy. In particular, the formation of the InAs/GaSb (GaSb segment on InAs stem
Despite advances in targeted therapies, the treatment of advanced melanoma remains an exercise in disease management, hence a need for biomarkers for identification of at risk primary melanoma patients. In this study we aimed to assess the prognostic value of TERT promoter mutations in primary melanomas. DNA from 300 patients with stage I/II melanoma was sequenced for TERT promoter and BRAF/NRAS m
Mutations in the promoter of the telomerase reverse transcriptase (TERT) and fibroblast growth factor receptor 3 (FGFR3) genes constitute the most recurrent somatic alterations in urothelial carcinoma of bladder. In this study, we screened DNA from 327 urothelial bladder carcinomas from well-documented patients, with different stages and grades and known TERT promoter mutational status, for FGFR3
Background: The majority of human cancers arise from cells unable to maintain genomic stability. Recent prospective studies indicated that enhanced chromosomal aberrations (CAs) frequencies are predictive of gastrointestinal and lung cancers. However, studies on incident cancer patients are lacking; thus, we investigated chromosomal damage in newly diagnosed cancer patients and healthy individuals
Background: Lymphoid neoplasms are a heterogeneous group of cancers that originate in the lymphatic cells of the immune system. Several risk factors have been identified or suggested, but they all account for only a small proportion of the lymphoid neoplasm incidence. It has been hypothesised that regular exercise may modulate the immune system and thereby reduce the risk of developing the disease
Offenders with high psychopathic traits and/or antisocial personality disorder (ASPD) are hypothesised to experience less guilt and less responsibility for their actions than offenders without these problems. These hypotheses were tested and partly substantiated. The study investigates blame attributions and guilt feeling using Gudjonsson Blame Attribution Inventory-Revised (GBAI-R) for 177 young
Children diagnosed with noncentral nervous system solid cancers (NCNSSC) experience several adverse late effects, including second malignant neoplasm. The aim of our study was to assess the risk of specific second malignancies after a childhood NCNSSC. Diagnosis and follow-up data on 10,988 cases of NCNSSC in children (0-14 years) were obtained from 13 registries. Standardized incidence ratios (SI
This paper explains and empirically assesses the channels through which Population aging may impact on income-related health inequality. Long panel data of Swedish individuals is used to estimate the observed trend in income-related health inequality, measures by the concentration index (CI). A decomposition procedure based on a fixed effects model is used to clarify the channels by which populati
To examine the role of gender, age at immigration and length of stay on incidence trends of common cancers, we studied risk of colorectal, lung, breast and prostate cancers in immigrants to Sweden from 1958 to 2008. The nationwide Swedish Family-Cancer Database was used to calculate standardized incidence ratios for common cancers among immigrants compared to Swedes. Immigrants were classified int
An understanding of the absorption of light is essential for efficient photovoltaic and photodetection applications with III-V nanowire arrays. Here, we correlate experiments with modeling and verify experimentally the predicted absorption of light in InP nanowire arrays for varying nanowire diameter and length. We find that 2,000 nm long nanowires in a pitch of 400 nm can absorb 94% of the incide
A disadvantage of prostate-specific antigen (PSA) for the early detection of prostate cancer (PCa) is that many men must be screened, biopsied, and diagnosed to prevent one death.
Objectives: Short relative telomere length (RTL) is associated with vascular ageing, inflammation and cardiovascular risk factors. Previous studies have reported an association between abdominal aortic aneurysm and short RTL. The presence of atherosclerosis among patients with aneurysm disease may, however, be a confounder. The aim was to explore the associations between short RTL and aneurysm dis
The Tumbleweed (TW) is a concept for an artificial, tri-pedal, protein-based motor designed to move unidirectionally along a linear track by a diffusive tumbling motion. Artificial motors offer the unique opportunity to explore how motor performance depends on design details in a way that is open to experimental investigation. Prior studies have shown that TW's ability to complete many successive
By measuring 1/f-noise in wrap-gated InAs nanowire metal-oxide-semiconductor field-effect transistors with transport dominating, controllably, in either an inner, core channel, or an outer, surface channel, it is possible to accurately evaluate the material quality related Hooge-parameter, alpha(H), with reduced interference from the surface properties. The devices show low values of alpha(H) simi
