Prenatal exposures to mixtures of endocrine disrupting chemicals and sex-specific associations with children's BMI and overweight at 5.5 years of age in the SELMA study

Background: Prenatal exposure to mixtures of endocrine disrupting chemicals (EDC) has the potential to disrupt human metabolism. Prenatal periods are especially sensitive as many developmental processes are regulated by hormones. Prenatal exposure to EDCs has inconsistently been associated with children's body mass index (BMI) and obesity. The objective of this study was to investigate if prenatal

Predictors of diagnostic conversion from major depression to bipolar disorder : A Swedish national longitudinal study

Background It is clinically important to predict the conversion of major depression (MD) to bipolar disorder (BD). Therefore, we sought to identify related conversion rates and risk factors. Methods This cohort study included the Swedish population born from 1941 onward. Data were collected from Swedish population-based registers. Potential risk factors, including family genetic risk scores (FGRS)

Cotinine concentrations in maternal serum and amniotic fluid during pregnancy and risk of testicular germ cell cancer in the offspring : A prospective nested case-control study

Maternal smoking in pregnancy may increase the risk of testicular germ cell cancer (TGCC) in offspring, but current evidence remains inconclusive. We performed a nested case-control study using cotinine measurements in maternal serum and amniotic fluid as a biomarker for tobacco exposure during pregnancy. A total of 654 males with maternal serum (n = 359, ncases/controls = 71/288) and/or amniotic

Hypertension : pathophysiology and relevance to the cardiometabolic syndrome

High blood pressure, or hypertension, is the leading single risk factor for the global burden of disease. Hypertension often coexists with several anthropometric and metabolic abnormalities, including abdominal obesity, dyslipidemia, and glucose intolerance—in combination referred to as metabolic (or cardiometabolic) syndrome. Indeed, hypertension occurs in a large proportion of those with metabol

Gain and bandwidth of InP nanowire array photodetectors with embedded photogated InAsP quantum discs

Here we report on the experimental results and advanced self-consistent real device simulations revealing a fundamental insight into the non-linear optical response of n+-i-n+ InP nanowire array photoconductors to selective 980 nm excitation of 20 axially embedded InAsP quantum discs in each nanowire. The optical characteristics are interpreted in terms of a photogating mechanism that results from

Association of Preterm Birth with Long-term Risk of Heart Failure into Adulthood

Importance: Preterm birth has been associated with increased risk of heart failure (HF) early in life, but its association with new-onset HF in adulthood appears to be unknown. Objective: To determine whether preterm birth is associated with increased risk of HF from childhood into mid-adulthood in a large population-based cohort. Design, Setting, and Participants: This national cohort study was c

Semiconductor nanowire array for transparent photovoltaic applications

The surface area of a building that could potentially be used for Building Integrated Photovoltaics would increase dramatically with the availability of transparent solar cells that could replace windows. The challenge is to capture energy from outside the visible region (UV or IR) while simultaneously allowing a high-quality observation of the outside world and transmitting sufficient light in th

Age-specific seasonal influenza vaccine effectiveness against different influenza subtypes in the hospitalized population in lithuania during the 2015–2019 influenza seasons

Background: Continuous monitoring of seasonal influenza vaccine effectiveness (SIVE) is needed due to the changing nature of influenza viruses and it supports the decision on the annual update of vaccine composition. Age-specific SIVE was evaluated against different influenza sub-types in the hospitalized population in Lithuania during four influenza seasons. Methods: A test-negative case-control

Incidence of ICD-based diagnoses of alcohol-related disorders and diseases from swedish nationwide registers and suggestions for coding

Aim: To improve consistency between register studies in Sweden and ensure valid comparisons of possible changes in alcohol-related disorders and diseases (ARDDs) over time, we propose a definition of ARDDs. Based on this definition, we examined Sweden’s incidence rates of ARDDs from 1970 to 2018 in non-primary healthcare settings (inpatient and outpatient). Methods: Swedish Society of Epidemiology

General Trends in Core-Shell Preferences for Bimetallic Nanoparticles

Surface segregation phenomena dictate core-shell preference of bimetallic nanoparticles and thus play a crucial role in the nanoparticle synthesis and applications. Although it is generally agreed that surface segregation depends on the constituent materials' physical properties, a comprehensive picture of the phenomena on the nanoscale is not yet complete. Here we use a combination of molecular d

The Structure of the Active Pd State during Catalytic Carbon Monoxide Oxidization

Using grazing incidence X-rays and X-ray photoelectron spectroscopy during the mass transfer limited catalytic oxidation of CO, the long-range surface structure of Pd(100) was investigated. Under the reaction conditions of 50:4 O2 to CO, 300 mbar pressure, and temperatures between 200 and 450 °C, the surface structure resulting from oxidation and the subsequent oxide reduction was elucidated. The

DNA Repair Gene Polymorphisms and Chromosomal Aberrations in Exposed Populations

DNA damage and unrepaired or insufficiently repaired DNA double-strand breaks as well as telomere shortening contribute to the formation of structural chromosomal aberrations (CAs). Non-specific CAs have been used in the monitoring of individuals exposed to potential carcinogenic chemicals and radiation. The frequency of CAs in peripheral blood lymphocytes (PBLs) has been associated with cancer ri

High conversion hydrogen peroxide microchannel reactors : Design and two-phase flow instability investigation

Novel micro-scale reaction devices are progressing in various applications. Whereas, specialized gas-producing reactors of high conversion at micro/mini scale remain challenging and are rarely explored, but are needed urgently in new generation vehicles and aerospace applications.
