In this report we explore the structural and optical properties of GaAs/AlGaAs heterostructure nanowires grown by metalorganic vapour phase epitaxy using gold seed-particles. The optical studies were done by low-temperature cathodoluminescence (CL) in a scanning electron microscope (SEM). We perform a systematic investigation of how the nanowire growth-temperature affects the total photon emission
Fluorescence diffuse optical tomography (FDOT) is an emerging biomedical imaging technique that can be used to localize and quantify deeply situated fluorescent molecules within tissues. However, the potential of this technique is currently limited by its poor spatial resolution. In this work, we demonstrate that the current resolution limit of FDOT can be breached by exploiting the nonlinear powe
The shelterin complex protects chromosomal ends by regulating how the telomerase complex interacts with telomeres. Following the recent finding in familial melanoma of inactivating germline mutations in POT1, encoding a member of the shelterin complex, we searched for mutations in the other five components of the shelterin complex in melanoma families.
In this study, nickel pattern electrodes were electrochemically investigated in a three-electrode setup, operating both with H-2/H2O and CO/CO2 atmospheres. Heating introduced structural differences in the nickel layer among the pattern electrodes, which appear to affect the electrode performance. Both dense and porous nickel pattern electrodes were formed by heating. Holes appeared in the nickel
Because of a low prevalence of severe carotid stenosis in the general population, screening for presence of asymptomatic carotid artery stenosis (ACAS) is not warranted. Possibly, for certain subgroups, screening is worthwhile. The present study aims to develop prediction rules for the presence of ACAS (>50% and >70%).
We have investigated the growth of self-catalyzed GaAs/GaAsxSb1-x core-shell nanowires directly on Si(111) substrates by molecular beam epitaxy. The compositions of the GaAsxSb1-x shells are tuned in a wide range where the Sb-content is varied from 10 to similar to 70%, covering the miscibility gap. In addition, the GaAsxSb1-x shells are grown on both zinc blende (ZB) and wurtzite (WZ) crystal str
Carcinogenic aromatic amines derived from hair dyes have recently received new attention. One of these is ortho (o)-toluidine, which is classified as carcinogenic to humans.
Microchip-based free flow acoustophoresis (FFA) in combination with two-dimensional cell prefocusing enables concurrent multiple target outlet fractionation of leukocytes into subpopulations (lymphocytes, monocytes, and granulocytes); we report on this method here. We also observed significantly increased accuracy in size-based fractionation of microbeads as compared to previously presented FFA mu
Certified randomness guaranteed to be unpredictable by adversaries is central to information security. The fundamental randomness inherent in quantum physics makes certification possible from devices that are only weakly characterized, i.e., requiring little trust in their implementation. It was recently shown that the amount of certifiable randomness can be improved using the so-called entropy ac

Background: Systemic lupus erythematosus (SLE) is an autoimmune disease with a heterogenous clinical picture. This study aimed to link genetic SLE predisposition with relevant clinical manifestations. Method: Datasets best corresponding to the 11 American College of Rheumatology 1982 (ACR-82) classification criteria for SLE in a large, public database (FinnGen consortium, >218,000 individuals) wer
Background: This study aimed to compare the effect on postoperative complications of combined prehabilitation targeting predefined co-existing risky SNAP factors with usual preoperative routines in surgical patients. Methods: This systematic review followed the PRISMA 2020 guideline and the protocol (CRD42022282611). Five databases were searched from inception to November 7, 2022 for randomised co
During graded exercise, systolic blood pressure (SBP) is expected to increase linearly, but other responses are observed. To date, a framework for algorithmic assessment of the shape of the SBP response is lacking, making its physiological and clinical relevance poorly understood. We aimed to algorithmically identify distinct SBP response shapes and analyze their association with clinical factors
Background: Standardised language tests provide a reliable framework for assessing language deficits in individuals with aphasia, but have long been lacking for various languages, including Swedish. The purpose of this study was to examine the diagnostic accuracy and establish the norm-references of the Swedish version of the Comprehensive Aphasia Test (CAT-S). Methods: Consecutive patients with a
Background: Chronic low-grade inflammation is a well-known risk factor for coronary heart disease (CHD) and future cardiovascular events. Anti-inflammatory therapy can reduce the risk of ischemic cardiovascular disease (CVD) events following myocardial infarction (MI). However, it remains unknown to what extent inflammation at the time of an acute event predicts long-term outcomes. We explored whe
Background: Familial clustering of initial primary lung cancer (IPLC) may be related to shared smoking habits, other environmental exposures and hereditary factors, but whether familial risk also influences the risk of second primary LC (SPLC) is not well known. We aimed to carry out a family study between first-degree relatives on SPLCs in Sweden. Methods: Population data on Swedish family relati
Background: Several case reports have recounted hiccups as a possible symptom of cancer, but potential associations in large study samples have not been examined. Methods: This population-based cohort study examined associations between hiccups and subsequent cancer diagnoses. Standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) were calculated. Results: Of 8466 patients diagnos
Injury prevention programmes can reduce injuries in youth team sports, including handball. However, real-world effectiveness and impact of such programmes are limited due to poor implementation. To address this in Swedish youth handball, the 'Implementing injury Prevention training ROutines in TEams and Clubs in youth Team handball' (I-PROTECT) programme was co-created with end-users, including co
Hard turning offers a cost-effective alternative to traditional grinding, yet the tool wear progression limits the broader industrial adoption. During hard turning, the surface microstructure of AISI 52100 steel transforms into a nanocrystalline structure known as white layer, accompanied by significant surface residual stresses. With optimal cutting conditions, surfaces develop nanocrystalline mi
