The relationship between the metabolic syndrome and arterial wall thickness : A mosaic still to be interpreted

Background and aims We aimed to identify clusters of metabolic syndrome (MetS) components, risky for extremely high intima-media thickness. Methods We studied 41,513 volunteers (men and women) from eleven cohorts worldwide, participating in the MARE (Metabolic syndrome and Artery REsearch) Consortium. Results Specific clusters of MetS components - high triglycerides-high blood pressure-abdominal o

Patterns of metastasis in colon and rectal cancer

Investigating epidemiology of metastatic colon and rectal cancer is challenging, because cancer registries seldom record metastatic sites. We used a population based approach to assess metastatic spread in colon and rectal cancers. 49,096 patients with colorectal cancer were identified from the nationwide Swedish Cancer Registry. Metastatic sites were identified from the National Patient Register

Genetic Susceptibility to Bortezomib-Induced Peripheral Neuroropathy : Replication of the Reported Candidate Susceptibility Loci

The introduction of proteasome inhibitors in the treatment of multiple myeloma (MM) patients has been a therapeutic success. Peripheral neuropathy (PNP) remains one of the most frequent side-effects experienced by patients who receive these novel agents. Recent investigations on the mechanisms of PNP in patients treated with bortezomib have suggested genetic susceptibility to neurotoxicity. We use

Time scales for Majorana manipulation using Coulomb blockade in gate-controlled superconducting nanowires

We numerically compute the low-energy spectrum of a gate-controlled superconducting topological nanowire segmented into two islands, each Josephson coupled to a bulk superconductor. This device may host two pairs of Majorana bound states and could provide a platform for testing Majorana fusion rules. We analyze the crossover between (i) a charge-dominated regime utilizable for initialization and r

Measurements of the spin-orbit interaction and Landé g factor in a pure-phase InAs nanowire double quantum dot in the Pauli spin-blockade regime

We demonstrate direct measurements of the spin-orbit interaction and Landé g factors in a semiconductor nanowire double quantum dot. The device is made from a single-crystal pure-phase InAs nanowire on top of an array of finger gates on a Si/SiO2 substrate and the measurements are performed in the Pauli spin-blockade regime. It is found that the double quantum dot exhibits a large singlet-triplet

Majorana bound state in a coupled quantum-dot hybrid-nanowire system

Hybrid nanowires combining semiconductor and superconductor materials appear well suited for the creation, detection, and control of Majorana bound states (MBSs). We demonstrate the emergence of MBSs from coalescing Andreev bound states (ABSs) in a hybrid InAs nanowire with epitaxial Al, using a quantum dot at the end of the nanowire as a spectrometer. Electrostatic gating tuned the nanowire densi

k.p theory of freestanding narrow band gap semiconductor nanowires

We report on a theoretical study of the electronic structures of freestanding nanowires made from narrow band gap semiconductors GaSb, InSb and InAs. The nanowires are described by the eight-band k.p Hamiltonians and the band structures are computed by means of the finite element method in a mixture basis consisting of linear triangular elements inside the nanowires and constrained Hermite triangu

Polarity dependent strongly inhomogeneous In-incorporation in GaN nanocolumns

In this work, GaN/InGaN/GaN nanocolumns (NCs) have been grown by molecular beam epitaxy. Selective area growth (SAG) and self-organized growth (SOG) were performed simultaneously in patterned and unpatterned regions of the same substrate, respectively. The resulting structures show different tip morphologies and structural properties due to the different polarity along the growth direction, namely

Effect of Type 1 Diabetes on School Performance in a Dynamic World : New Analysis Exploring Swedish Register Data

This paper investigates if the effect of type 1 diabetes mellitus (T1DM) on school performance has changed over time using national Swedish population register data. The issue is of interest because management and treatment of the disease have improved over the last decades and, furthermore, because of changes in the educational grading system. Despite these changes, data indicate a persistent neg

Growth and optical properties of InxGa1−xP nanowires synthesized by selective-area epitaxy

Ternary III–V nanowires (NWs) cover a wide range of wavelengths in the solar spectrum and would greatly benefit from being synthesized as position-controlled arrays for improved vertical yield, reproducibility, and tunable optical absorption. Here, we report on successful selective-area epitaxy of metal-particle-free vertical InxGa1−xP NW arrays using metal–organic vapor phase epitaxy and detail t

Incorporation and effects of impurities in different growth zones within basic ammonothermal GaN

The ammonothermal method is one of the most promising candidates for large-scale bulk GaN growth due to its scalability and high crystalline quality. However, emphasis needs to be put on understanding the incorporation and effects of impurities during growth. This article discusses how impurities are incorporated in different growth zones in basic ammonothermal GaN, and how they affect the structu

Body mass does not impact the clinical response to intravenous abatacept in patients with rheumatoid arthritis. Analysis from the “pan-European registry collaboration for abatacept (PANABA)

Some evidences suggest that obesity impairs the effectiveness of TNF inhibitors. We examined the impact of body mass index (BMI) on the clinical effectiveness of abatacept in rheumatoid arthritis (RA) patients. This is a pooled analysis of 10 prospective cohorts of RA patients. All patients with available BMI were included in this study. The primary endpoint was drug retention of abatacept in the

Blood pressure treatment levels and choice of antihypertensive agent in people with diabetes mellitus : an overview of systematic reviews

OBJECTIVE:: Multiple systematic reviews address the effect of antihypertensive treatment in people with diabetes. Here, we summarize current systematic reviews concerning antihypertensive treatment effect at different blood pressure (BP) levels, and relative treatment effect of different antihypertensive agents. METHODS:: We searched MEDLINE, BIOSIS, DARE and CDSR during years 2005–2016. Eligibili

The probability density function tail of the Kardar-Parisi-Zhang equation in the strongly non-linear regime

An analytical derivation of the probability density function (PDF) tail describing the strongly correlated interface growth governed by the nonlinear Kardar-Parisi-Zhang equation is provided. The PDF tail exactly coincides with a Tracy-Widom distribution i.e. a PDF tail proportional to exp (cw2 3/2), Where w 2 is the the width of the interface. The PDF tail is computed by the instanton method in t

Modifying the emission of light from a semiconductor nanowire array

Semiconductor nanowire arrays have been identified as a promising platform for future light emitting diodes (LEDs), for example, due to the materials science freedom of combining lattice-mismatched materials in them. Furthermore, the emission of light from nanowires can be tailored by designing their geometry. Such tailoring could optimize the emission of light to the top side as well as enhance t

Long-Time Voice Accumulation During Work, Leisure, and a Vocal Loading Task in Groups With Different Levels of Functional Voice Problems

Objective: The study aimed to examine the vocal behavior and self-assessed vocal health in women with varying everyday vocal load and functional voice problems, including patients with functional dysphonia, in three conditions: work, leisure, and a vocal loading task (VLT). Study Design: This is a longitudinal controlled, clinical trial. Methods: Fifty (n = 50) female subjects were tracked during

Familial Associations Between Prostate Cancer and Other Cancers

Prostate cancer (PCa) has a large familial component, but understanding of its genetic basis is fragmentary. Breast cancers may be associated with PCa, but whether this is true for other tumor types is poorly established. We used a novel approach to study familial associations of any type of cancer with PCa. We assessed the relative risk (RR) for all types of tumors as a function of the number of
