Racial/ethnic differences in HIV testing: An application of the health services utilization model

SAGE Open Medicine, 2018
This study applying the health services utilization model examined the importance of predisposing, enabling, and need variables to the social mechanisms explaining lifetime HIV testing across racial/ethnic groups. Data for the study were derived from the

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Empowerment, gender, and household dynamics in households receiving social cash transfers in Eastern and Southern Africa: evidence from a systematic review

Development Studies Research
Understanding the gendered intrahousehold dynamics of empowerment in social cash transfer programes is crucial for enhancing the effectiveness of programs in reducing poverty and promoting sustainable development. This systematic review draws on Kabeer’s

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Lysyl oxidase (LOX)‐mediated remodeling of the extracellular matrix

FEBS Letters, EarlyView.
The lysyl oxidase (LOX) family of enzymes drives extracellular matrix remodeling by oxidizing collagen, elastin, and fibronectin, promoting covalent cross‐link formation. This activity regulates tissue architecture and mechanical properties, while its dysregulation contributes to fibrosis, cardiovascular disease, glaucoma, connective tissue disorders ...

An Occupational Job Strain Index based on five Norwegian nationwide surveys of living conditions on work environment

BMC Research Notes
Objectives This paper aims to provide comprehensive documentation of the Occupational Job Strain Index (JSI), developed using data from the Norwegian nationwide Survey of Living Conditions conducted in 2006, 2009, 2013, 2016, and 2019.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Youths over 18 receiving support from the child welfare service: evolving motivation in the interaction between the youth and the caseworker

Nordic Social Work Research
This article focuses on the interaction between youths and caseworkers and how it influences youths’ motivation during emerging adulthood. The study is based on qualitative interviews with 10 youths aged 18–23 and six child welfare caseworkers.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
