From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

The effects of methodological limitations in the study of butterfly behavior and demography: a daily study of Vanessa atalanta (Lepidoptera: Nymphalidae) for 22 years

open access: yesRevista de Biología Tropical, 2000
Normally, butterfly behavior and population size are studied intensively for brief periods or occasionally for long periods, not in detail for long periods, producing an incomplete view in both cases.

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

open access: yesFEBS 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.

Population trends, convictions and imprisonment: Demographic divergence, dichotomy and diversity [PDF]

open access: yes, 2006
The links between population patterns and trends, and policy and planning for the justice system is important. The trends in the number of convictions and imprisonments by regional councils are investigated for the period 1986 to 2001. This does not just

Precision of Nest Method in Estimating Orangutan Population and Determination of Important Ecological Factors for Management of Conservation Forest

open access: yesJurnal Manajemen Hutan Tropika, 2012
Orangutan as an umbrella species is closely interlinked with sustainable forest management meaning that the protection of this species has implications on the protection of other species and maintain ecosystem stability.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS 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

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
