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.

Euro area production function and potential output: a supply side system approach [PDF]

open access: yes
In this paper, we present a three equation supply-side model based on aggregation across sectors with sector specific mark-ups and the technology parameters of the production function.

Weighted Hardy and potential operators in the generalized Morrey spaces [PDF]

open access: yes, 2011
We study the weighted p -> q-boundedness of the multi-dimensional Hardy type operators in the generalized Morrey spaces L-p.phi(R-n, w) defined by an almost increasing function phi(r) and radial type weight w(vertical bar x vertical bar).

Soil organic carbon, pH, and ammonium nitrogen controlled changes in bacterial community structure and functional groups after forest conversion

open access: yesFrontiers in Forests and Global Change
IntroductionLand-use changes significantly impact soil properties in forests, which is an area of concern. Therefore, the effects of changing forest types on soil microbial communities and their functions in northern subtropical forest regions need to be

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

On certain nonlinear elliptic systems with indefinite terms

open access: yesElectronic Journal of Differential Equations, 2002
We consider an elliptic quasi linear systems with indefinite term on a bounded domain. Under suitable conditions, existence and positivity results for solutions are given. Submitted April 2, 2002. Published October 2, 2002.

Mechanism of soil microbial community degradation under long-term tomato monoculture in greenhouse

open access: yesFrontiers in Microbiology
Tomato (Solanum lycopersicum L.), an economically significant crop, is frequently cultivated in greenhouses under continuous monoculture systems. Motivated by intensive agricultural practices and economic incentives, continuous cropping has become ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Cobb-Douglas Production Function: The Case of a Converging Economy [PDF]

open access: yes
The Cobb-Douglas production function is often used to analyse the supply-side performance and measurement of a country’s productive potential. This functional form, however, includes the assumption of a constant share of labor in output, which may be too

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.
