Mitochondria and metazoan epigenesis [PDF]

open access: yesSeminars in Cell & Developmental Biology, 2009
In eukaryotes, mitochondrial activity controls ATP production, calcium dynamics, and redox state, thereby establishing physiological parameters governing the transduction of biochemical signals that regulate nuclear gene expression. However, these activities are commonly assumed to fulfill a 'housekeeping' function: necessary for life, but an ...

An Anaerobic Microbial Community Mediates Epigenetic Native Sulfur and Carbonate Formation During Replacement of Messinian Gypsum at Monte Palco, Sicily

open access: yesGeobiology, Volume 23, Issue 2, March/April 2025.
ABSTRACT The microbially mediated replacement of sulfate‐bearing evaporites by authigenic carbonate and native sulfur under anoxic conditions is poorly understood. Sulfur‐bearing carbonates from the Monte Palco ridge (Sicily) replacing Messinian gypsum were therefore studied to better characterize the involved microorganisms.

Association Between rs920778 Polymorphisms and Cancer Risk: An Updated Meta‐Analysis

open access: yesGenetics Research , Volume 2025, Issue 1, 2025.
Background: A growing number of studies are exploring the association between HOTAIR rs920778 polymorphisms and cancer risk, but to date, there has been controversy and uncertainty. Preliminary evidence suggests that this polymorphism may influence cancer susceptibility, particularly in Asian populations and specific cancer types such as cervical ...

Evolutionary ecology of the North Atlantic Talitridae (Crustacea, Amphipoda): A review [PDF]

open access: yesZoosystematics and Evolution
Four primary estuarine/marine ecotopes recognized in the North Atlantic continental littoral and continental terrestrial margins give rise to the following ecotypes: wrack generalists (=beach-hoppers), psammophilic talitrids (=sandburrowing-hoppers ...

Epigenesis of Pure Reason and the Source of Pure Cognitions [PDF]

open access: yes, 2018
Kant describes logic as “the science that exhaustively presents and strictly proves nothing but the formal rules of all thinking”. (Bviii-ix) But what is the source of our cognition of such rules (“logical cognition” for short)?

Bringing forth mathematical concepts: signifying sensorimotor enactment in fields of promoted action [PDF]

open access: yes, 2014
Inspired by Enactivist philosophy yet in dialog with it, we ask what theory of embodied cognition might best serve in articulating implications of Enactivism for mathematics education. We offer a blend of Dynamical Systems Theory and Sociocultural Theory

Perceptions of plant breeding methods–from ‘phenotypic selection’ to ‘genetic modification’ and ‘new breeding technologies’

open access: yesNew Zealand Journal of Agricultural Research, Volume 67, Issue 6, Page 621-669, December 2024.
ABSTRACT Plant breeding has been closely aligned with the development of civilisations and continues to be important for the supply of nutritious food and a key factor in reducing poverty and hunger. Plant breeding uses a range of techniques for both expanding and exploiting the genetic potential of plants.
