The complex pseudodielectric function of Ge and Si from femtosecond pump-probe spectroscopic ellipsometry with 267, 400, and 800 nm pump-pulse wavelengths is analyzed by fitting analytical lineshapes to the second derivatives of the pseudodielectric function with respect to energy. This yields the critical point parameters (threshold energy, lifetime broadening, amplitude, and excitonic phase angl

Long life requires individuals to defend themselves against pathogens over prolonged periods of time whilst minimising damage to themselves. In vertebrates, pathogen defence is provided by two integrated systems, innate and adaptive immunity. Innate immunity is relatively nonspecific, resulting in collateral damage to hosts, and does not involve canonical immunological memory. In contrast, adaptiv

Objective: This study aimed to estimate the association between potential risk factors and common vaginal infections using nationwide primary health care and other national registers. Methods: An open cohort study consisting of 2,357,711 women aged 15 years to 50 years (2001 to 2018) was conducted in Sweden. The outcomes were first event of vulvovaginal candidiasis (VVC) and bacterial vaginosis (B

Aiming to compare capability across persons with impairments using and not using assistive products and persons without impairments in Bangladesh for 16 different functionings, we contrast two sets of self-reported cross-sectional data from eight districts of Bangladesh: (i) data from persons with hearing impairment not using hearing aids, persons with hearing impairment using hearing aids and per

Introduction: Few, if any, prior studies have considered whether undetermined intent (UDI) deaths and suicide deaths differ with respect to genetic liability for suicidal behavior or psychopathology. Methods: The authors used Swedish national registry data to identify suicide deaths (N = 31,835) and UDI deaths (N = 10,623); sociodemographic covariates; and registrations for psychopathology. Family

Background: Considering the adverse reactions to vaccination against coronavirus disease 2019 (COVID-19), some people, particularly the elderly and those with underlying medical conditions, are hesitant to be vaccinated. This study aimed to explore the prevalence of adverse reactions and provide direct evidence of vaccine safety, mainly for the elderly and people with underlying medical conditions

AIMS: To assess the association of genetically-predicted lipid traits and lipid-modification via licensed or investigational targets with heart failure (HF).METHODS AND RESULTS: Two-sample Mendelian randomization (MR) study was conducted using summary-level genome-wide association studies (GWASs) from UK Biobank and HERMES Consortium. Genetic variants obtained from UK Biobank GWAS data were select

Background: Periprosthetic joint infection (PJI) following total knee arthroplasty (TKA) is a severe complication in terms of disability, morbidity, and cost. We performed a study to investigate whether early PJI (within 90 days of primary TKA) is associated with increased mortality. Secondary aims were to compare mortality rates over time and between surgical treatment methods. Methods: Patients

Purpose: We aimed to analyze the risk of cardiomyopathies (CMPs) among first-generation and second-generation immigrants. Methods: All individuals aged 18 years of age and older, n = 6,123,661 in the first-generation study, and n = 4,587,764 in the second-generation study were analyzed. CMP was defined as at least one registered diagnosis in the National Patient Register between January 1, 1998 an

Objective To evaluate hydroxychloroquine (HCQ)-related retinal toxicity in the Systemic Lupus International Collaborating Clinics (SLICC) inception cohort. Methods Data were collected at annual study visits between 1999 and 2019. We followed patients with incident SLE from first visit on HCQ (time zero) up to time of retinal toxicity (outcome), death, loss-to-follow-up or end of study. Potential r

A microenvironment is an area with a specific composition of mainly extracellular matrix (ECM) components surrounding the cells. The tight interactions between matrix molecules and cells are very important, and it is now well known that the ECM components direct cell activity and function and regulate remodeling processes during both homeostasis and pathological conditions. The lung is a very comp

Background: Some groups of migrants have increased vulnerability to Sexually Transmitted Infections (STI) and Human Immunodeficiency Virus (HIV) transmission partly due to a lower uptake of disease preventive activities targeting the general population in receiving country. Limited access to economic and social resources and poor language skills may exacerbate exposure to sexual risks and utilizat

Insects have evolved diverse and remarkable strategies for navigating in various ecologies all over the world. In particular, central place foragers, such as bees and ants, have become renowned for their fascinating navigational capabilities. At the heart of insect navigation lies a brain area known as the central complex (CX). Functionally, the CX integrates world-centric sensory information with

Vi lever i en tid av snabb vetenskaplig och teknologisk utveckling. För 100 år sedan hade ingen kunnat drömma om de saker som helt har förändrat vår var- dag och hur vi uppfattar omvärlden; datorer, mobiltelefoner, Internet, rymdfart, våra upptäckter om universums barndom och avlägsna galaxer samt vår insyn i kvantfenomenens mikroskopiska värld. Idag står vi på tröskeln till en era formad av nanotWe live in a time of rapid scientific and technological advancement. People liv- ing 100 years ago could never dream of inventions like those having completely changed our way of life, and our perception of the world; computers, mobile phones, the Internet, space travel, unraveling the mysteries of the early universe and distant galaxies, and our insight into the microscopic world of quantum phe-

In this work, we present a novel self-aligned gate-last fabrication process for vertical nanowire metal-oxide-semiconductor field-effect transistors. The fabrication method allows for exposure dose-defined gate lengths and a local diameter reduction of the intrinsic channel segment, while maintaining thicker highly doped access regions. Using this process, InAs nanowire transistors combining good

Background: Many women of childbearing age are occupationally active, which leads to a large number of pregnancies potentially exposed to occupational exposures. Occupational noise has been identified as a risk factor for hearing impairment in adults. However, very few studies have assessed the effect of occupational noise on the fetus. Objectives: The aim of this study was to investigate whether

Objective To investigate the role of rheumatoid factor (RF) status and anti-citrullinated peptide antibody (ACPA) status as predictors of abatacept (ABA) effectiveness in patients with rheumatoid arthritis (RA). Methods We conducted a pooled analysis of data from 9 observational RA registries in Europe (ARTIS [Sweden], ATTRA [Czech Republic], BIOBADASER [Spain], DANBIO [Denmark], GISEA [Italy], NO

Distal radius fracture is an early indicator of osteoporosis, yet little is known about men with this fracture and osteoporosis prevalence. The purpose of this cross-sectional, controlled study was to evaluate bone mineral density (BMD) in men, from working age to the elderly, with distal radius fracture. Recruitment was as follows: men who fractured during 1999–2000 were evaluated retrospectively
