Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Psychometric properties of the WBIS/-M in a representative prebariatric sample – evidence for an improved 10-item version

Obesity Facts
Introduction The Weight Bias Internalization Scale and the Modified Weight Bias Internalization Scale are well-established self-report questionnaires for assessing weight bias internalization, which is widespread among bariatric patients.

Exploring differential item functioning in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)

BMC Musculoskeletal Disorders, 2012
Background The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is a widely used patient reported outcome in osteoarthritis. An important, but frequently overlooked, aspect of validating health outcome measures is to establish if ...

Item Bias in a Test of Reading Comprehension [PDF]

Applied Psychological Measurement, 1981
The possibility that certain features of items on a reading comprehension test may lead to biased esti mates of the reading achievement of particular sub groups of students was investigated. Eight nonover lapping subgroups of students were defined by the combinations of three factors: student grade level (fifth or sixth), income level of the ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

How value-glamour investors use financial information:UK evidence of investor’s confirmation bias [PDF]

, 2014
The paper investigates investor’s behaviour in the context of value–glamour investing and fundamental analysis, and provides a direct test of the confirmation bias by bringing together the evidence from several strands of literature into a well-defined ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

The interaction between unit and item nonresponse in view of the reverse cooperation continuum [PDF]

The paper addresses two questions. First, is item nonresponse (INR) a precursor of panel attrition (UNR), as predicted by the theory of a latent cooperation continuum, or is the interrelation of another type?
