Two-age islet-autoantibody screening for childhood type 1 diabetes : a prospective cohort study

Background: Early prediction of childhood type 1 diabetes reduces ketoacidosis at diagnosis and provides opportunities for disease prevention. However, only highly efficient approaches are likely to succeed in public health settings. We sought to identify efficient strategies for initial islet autoantibody screening in children younger than 15 years. Methods: We harmonised data from five prospecti

Long-term development of lens fluorescence in a twin cohort : Heritability and effects of age and lifestyle

The blue-green autofluorescence of the ocular lens increases with age, glycemia and smoking, as the irreplaceable structural proteins of the lens slowly accumulate damage from the encounter with reactive molecular species. We have conducted a prospective study of lens autofluorescence over two decades in a twin cohort. The study included 131 phakic, non-diabetic adult twins (median age at follow-u

Exploring Global Climate Policy Futures and Their Representation in Integrated Assessment Models

The Paris Agreement, adopted in 2015, paved the way for a new hybrid global climate governance architecture with both bottom-up and top-down elements. While governments can choose individual climate goals and actions, a global stocktake and a ratcheting-up mechanism have been put in place with the overall aim to ensure that collective efforts will prevent increasing adverse impacts of climate chan

High-throughput muscle fiber typing from RNA sequencing data

Background: Skeletal muscle fiber type distribution has implications for human health, muscle function, and performance. This knowledge has been gathered using labor-intensive and costly methodology that limited these studies. Here, we present a method based on muscle tissue RNA sequencing data (totRNAseq) to estimate the distribution of skeletal muscle fiber types from frozen human samples, allow

Double Isothermal Amplification and CRISPR-Cas12a for Sensitive Detection of Citrinin

An analytical method is developed for ultrasensitive detection of citrinin using double isothermal amplification and CRISPR-Cas12a. Gold nanoparticles (AuNPs) modified with antigen and thiol-terminated, single-strand DNA (ssDNA) are used as a probe. The antigen-modified AuNPs compete with citrinin to bind to magnetic beads coated with an anticitrinin antibody. After a simple magnetic separation, t

Photoinduced Polaron Formation in a Polymerized Electron-Acceptor Semiconductor

Polymerized small molecular acceptor (PSMA) based all-polymer solar cells (all-PSC) have achieved power conversion efficiencies (PCE) over 16%, and the PSMA is considered to hold great promise for further improving the performance of all-PSC. Yet, in comparison with that of the polymer donor, the photophysics of a polymerized acceptor remains poorly understood. Herein, the excited state dynamics i

Feasibility and acceptability of human papillomavirus self-sampling in a semi-urban area in northern Tanzania

Objective: To assess the feasibility and acceptability of HPV self-sampling in Arusha region, northern Tanzania, because the ability for women to self-collect HPV samples can help reduce the number of health facility visits and improve cervical cancer screening coverage rates. Methods: We conducted a facility- and community-based cross-sectional study among 350 women aged 25–55 years in Arumeru di

Glyphosate-based herbicide induces long-lasting impairment in neuronal and glial differentiation

Glyphosate-based herbicides (GBH) are among the most sold pesticides in the world. There are several formulations based on the active ingredient glyphosate (GLY) used along with other chemicals to improve the absorption and penetration in plants. The final composition of commercial GBH may modify GLY toxicological profile, potentially enhancing its neurotoxic properties. The developing nervous sys

The contralateral hip in slipped capital femoral epiphysis : Is there an easy-to-use algorithm to support a decision for prophylactic fixation?

Purpose: To identify a specific factor that can support the decision for prophylactic fixation in unilateral slipped capital femoral epiphysis. Methods: This retrospective cohort study included a total national population of 379 children diagnosed with slipped capital femoral epiphysis from 2007 to 2013. Regression analysis used information on slip severity, clinical classification of the index hi

Nuclear spectra from low-energy interactions

A method to describe spectra starting from nuclear density functionals is explored. The idea is based on postulating an effective Hamiltonian that reproduces the stiffness associated with collective modes. The method defines a simple form of such an effective Hamiltonian and a mapping to go from a density functional to the corresponding Hamiltonian. In order to test the method, the Hamiltonian is

Malmö POTS symptom score : Assessing symptom burden in postural orthostatic tachycardia syndrome

BACKGROUND: Postural orthostatic tachycardia syndrome (POTS) is a common cardiovascular autonomic disorder characterized by excessive heart rate (HR) increase on standing and symptoms of orthostatic intolerance, posing significant limitations on functional capacity. No objective tool exists to classify symptom burden in POTS.METHODS: We conducted a case-control study in 62 POTS patients and 50 hea

Visual Evaluation of Ultrafast MRI in the Assessment of Residual Breast Cancer after Neoadjuvant Systemic Therapy : A Preliminary Study Association with Subtype

The purpose of this study was to investigate the diagnostic performance of ultrafast DCE (UF-DCE) MRI after the completion of neoadjuvant systemic therapy (NST) in breast cancer. In this study, MR examinations of 55 post-NST breast cancers were retrospectively analyzed. Residual tumor sizes were measured in the 20th phase of UF-DCE MRI, early and delayed phases of conventional DCE MRI, and high sp

Development, Debt, and Distress : Examining challenges to China’s Belt and Road Initiative through an analysis of Sri Lanka’s Debt Crisis

What can the situation in Sri Lanka tell us about China’s “Belt and Road” Initiative (BRI)? During Sri Lanka’s ongoing economic crisis, China initially seemed to take a step back, leaving everyone to wonder whether the Chinese Communist Party (CCP) would agree to restructure its debt in Sri Lanka. If Beijing agreed to help its “friend in need”, what would this entail for other BRI countries seekin

The Effect of Exercise for the Prevention and Treatment of Cancer-Related Lymphedema : A Systematic Review with Meta-analysis

Introduction The purpose of this systematic review and meta-analysis was to evaluate the effects of exercise on (i) the prevention of cancer-related lymphedema (CRL) and (ii) the treatment of CRL, lymphedema-associated symptoms, and other health outcomes among individuals with CRL. Methods An electronic search was undertaken for exercise studies measuring lymphedema and involving individuals at ri

Core competencies for a biomedical laboratory scientist - a Delphi study

BACKGROUND: After completing university education, biomedical laboratory scientists work in clinical laboratories, in biomedical research laboratories, in biotech, and in pharmaceutical companies. Laboratory diagnostics have undergone rapid development over the recent years, with the pace showing no signs of abatement. This rapid development challenges the competence of the staff and will most cer

Racial Disparities in Mortality During the 1918 Influenza Pandemic in United States Cities

Against a backdrop of extreme racial health inequality, the 1918 influenza pandemic resulted in a striking reduction of non-White to White influenza and pneumonia mortality disparities in United States cities. We provide the most complete account to date of these reduced racial disparities, showing that they were unexpectedly uniform across cities. Linking data from multiple sources, we then exami

Dipeptidyl peptidase 4 expression is not associated with an activated fibroblast phenotype in idiopathic pulmonary fibrosis

Dipeptidyl peptidase 4 (DPP4) has been proposed as a marker for activated fibroblasts in fibrotic disease. We aimed to investigate whether a profibrotic DPP4 phenotype is present in lung tissue from patients with idiopathic pulmonary fibrosis (IPF). The presence of DPP4 + fibroblasts in normal and IPF lung tissue was investigated using flow cytometry and immunohistology. In addition, the involveme
