Interlaboratory exercise to establish proficiency testing for sequencing of forensic STR and SNP markers

Massively parallel sequencing (MPS) is increasingly used in forensic DNA analysis for SNP and STR genotyping, though accredited proficiency tests remain limited. To address this, five forensic DNA laboratories from four countries participated in a study to assess MPS methods across different kits and platforms. In this study ForenSeq DNA Signature Prep Kit, ForenSeq MainstAY kit, Precision ID Glob

Influence of floral traits on visitation patterns in a miniature tropical stingless bee, Tetragonula iridipennis

Miniaturisation can influence the foraging behaviour of flower visitors by shaping their sensory systems, flight capabilities, and their compatibility with floral shapes and structures. For bees, vision is a primary sensory modality, and a reduction in eye size compromises the resolution and sensitivity of vision. In Tetragonula iridipennis, a diminutive tropical stingless bee common in South Asia

Educational inequalities in clinical presentation and pharmacological treatment of early type 2 diabetes : A Danish prevalence study

Aims: To examine how educational attainment impacts clinical presentation and pharmacological treatment at type 2 diabetes (T2D) diagnosis. Methods: Cross-sectional analysis of 10,020 individuals with recently diagnosed T2D enrolled in the Danish prospective DD2 cohort. Sex- and age-adjusted prevalence ratios (aPRs) for detailed clinical characteristics and pharmacotherapy were computed. Results:

Physical activity and weight are important predictors of health related quality of life in adults with congenital heart disease

Introduction: Traditional cardiovascular risk factors put patients with congenital heart disease (CHD) at increased risk for acquired cardiovascular disease and mortality – more so than patients without CHD. In the general population, health related quality of life (HRQoL) is associated with regular physical activity. It was the aim of this study to evaluate the most important predictors of HRQoL

Ambulance Nurses’ Experience of a Simulation Exercise Concerning Intimate Partner Violence

Aim: To qualitatively assess an intervention for ambulance nurses, including simulation training concerning intimate partner violence (IPV), and to describe the ambulance nurses’ experiences of their work after the intervention. Background: IPV is a common public health issue with serious consequences from individual and societal perspectives. Previous research indicates that deficits in knowledge

The effect of trauma quality improvement programme implementation on quality of life among trauma patients in urban India

Trauma accounts for around 4.4 million deaths annually and is among the leading causes of death, disproportionately affecting low- and middle-income countries. Trauma quality improvement programmes may reduce adverse patient outcomes but lack robust evidence. This study assessed the effect of implementing a trauma quality improvement programme using audit filters on health-related quality of life

Electrophoretic mobilities of neutral analytes and electroosmotic flow markers in aqueous solutions of Hofmeister salts

Small neutral organic compounds have traditionally the role of EOF markers in electrophoresis, as they are expected to have zero electrophoretic mobility in external electric fields. The BGE contains, however, ions that have unequal affinities to the neutral molecules, which in turn results in their mobilization. In this study we focused on two EOF markers-thiourea and DMSO, as well as on N-methyl

Release of halide ions from the buried active site of the haloalkane dehalogenase LinB revealed by stopped-flow fluorescence analysis and free energy calculations

Release of halide ions is an essential step of the catalytic cycle of haloalkane dehalogenases. Here we describe experimentally and computationally the process of release of a halide anion from the buried active site of the haloalkane dehalogenase LinB. Using stopped-flow fluorescence analysis and umbrella sampling free energy calculations, we show that the anion binding is ion-specific and follow

Hydration of hydroxyl and amino groups examined by molecular dynamics and neutron scattering

Neutron diffraction with isotopic substitution was performed on aqueous solutions of isopropyl alcohol and isopropylamine. The difference between these two measurements primarily contains information about the different hydration of the alcohol and amino group. This data is used as a test of the accuracy of molecular dynamic simulations of the same systems. Having established the level of accuracy

Specific potassium ion interactions facilitate homocysteine binding to betaine-homocysteine S-methyltransferase

Betaine-homocysteine S-methyltransferase (BHMT) is a zinc-dependent methyltransferase that uses betaine as the methyl donor for the remethylation of homocysteine to form methionine. This reaction supports S-adenosylmethionine biosynthesis, which is required for hundreds of methylation reactions in humans. Herein we report that BHMT is activated by potassium ions with an apparent KM for K+ of about

Guanidinium can both cause and prevent the hydrophobic collapse of biomacromolecules

A combination of Fourier transform infrared and phase transition measurements as well as molecular computer simulations, and thermodynamic modeling were performed to probe the mechanisms by which guanidinium (Gnd+) salts influence the stability of the collapsed versus uncollapsed state of an elastin-like polypeptide (ELP), an uncharged thermoresponsive polymer. We found that the cation's action wa

Effects of end-group termination on salting-out constants for triglycine

Salting-out constants for triglycine were calculated for a series of Hofmeister salts using molecular dynamics simulations. Three variants of the peptide were considered with both termini capped, just the N-terminus capped, and without capping. The simulations were supported by NMR and FTIR measurements. The data provide strong evidence that previous experimental values of salting-out constants as

Impacts of Conflict and Displacement on Myanmar Citizenship Pre and Post-2021

This research and policy brief focuses on conflict and displacement as key factorscontributing to statelessness and barriers to acquiring and holding Myanmar citizenship. The brief is designed as a working document for discussing important issues relevant for local governance during the revolution and national and state-level governance in the future. To aid in these conversations and policy devel

What Happened to the Incomes of the Rich during the Great Levelling? Evidence from Swedish Individual-Level Data, 1909–1950

We use individual-level income data from archived taxation lists to study top-income earners in Sweden from 1909 to 1950. Using information on 21,055 individual taxpayers in two elite areas in greater Stockholm, we show that top incomes fell in real terms over this period, at a stable pace without obvious connection to the Great Depression or the world wars. The peak of inequality was related to tWe use individual-level income data from archived taxation lists to study top-income earners in Sweden from 1909 to 1950.

Homeobox protein B6 and homeobox protein B8 control immune-cancer cell interactions in pancreatic cancer

Pancreatic ductal adenocarcinoma (PDAC) is a lethal cancer lacking effective drugs and therefore new treatment targets are needed. In this study, we define the role of homeobox protein B6 (HOXB6) and HOXB8 in controlling pancreatic cancer tumorigenesis and immune response. Transcriptomic analysis comparing human embryonic and PDAC tissue identified a large overlap of expression profiles suggesting

Isoleringens olika ansikten: Smittskydd och rörelsefrihet på äldreboenden

Covid-19-pandemin aktualiserade frågor om smittskyddsåtgärder inom äldreomsorgen, särskilt i relation till isolering av äldre. Denna artikel undersöker de rättsliga hinder som finns för att införa isolering – förstådd som ett krav på minimala kontakter med omgivningen – som åtgärd för att begränsa smittspridning på äldreboenden. Artikeln söker i synnerhet besvara frågan om vissa isoleringsåtgärder
