Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Comparison of field population growths of three cereal aphid species on winter wheat

open access: yesPlant Protection Science, 2003
Population growths of three aphid species colonising winter wheat stands, Metopolophium dirhodum, Rhopalosiphum padi and Sitobion avenae, were analysed by regression method.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Electoral redistribution in Australia : accommodating 150 years of demographic change [PDF]

open access: yes, 2012
Electoral redistribution (redistricting) is a process that seeks to advance the principle of ‘one vote, one value’ in the face of dynamic human populations.

Spiders (Araneae) from square samples and pitfall traps in coastal heathland, western Norway. Habitat preference, phenology and distribution

open access: yesFauna Norvegica
Square samples were taken at intervals of 3 - 4 weeks (early spring 1972 - late summer 1973) in a heterogenous plant association dominated by Calluna vulgaris and several moss species (Loc.I), and in a homogenous, humid Sphagnum mat (Loc.II) with very ...

Harmonia axyridis em árvores frutíferas e impacto sobre outros coccinelídeos predadores Harmonia axyridis in fruit trees and impact on other predator coccinellids

open access: yesPesquisa Agropecuária Brasileira, 2008
O objetivo deste trabalho foi avaliar a flutuação populacional de Harmonia axyridis em árvores frutíferas, durante dois anos (2004-2006), relacioná-la a variáveis abióticas e avaliar sua influência sobre outros coccinelídeos predadores, em Ponta Grossa ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
