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

Different life-histories of native and invasive Neogobius melanostomus and the possible role of phenotypic plasticity in the species’ invasion success

open access: yesKnowledge and Management of Aquatic Ecosystems, 2013
One of the most successful invasive fish species with negative impacts is round goby Neogobius melanostomus that has spread from its original Ponto-Caspian area to west and central Europe and even to North America.

Human nasal olfactory stem cells, purified as advanced therapy medicinal products, improve neuronal differentiation

open access: yesFrontiers in Neuroscience, 2022
BackgroundOlfactory ecto-mesenchymal stem cells (OE-MSC) are mesenchymal stem cells derived from the lamina propria of the nasal mucosa. They display neurogenic and immunomodulatory properties and were shown to induce recovery in animal models of spinal ...

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 ...

Crossovers between epigenesis and epigenetics. A multicenter approach to the history of epigenetics (1901-1975) [PDF]

open access: yes, 2014
The origin of epigenetics has been traditionally traced back to Conrad Hal Waddington's foundational work in 1940s. The aim of the present paper is to reveal a hidden history of epigenetics, by means of a multicenter approach.

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.

WHAT CAN PIAGET OFFER LONERGAN'S PHILOSOPHY OF BIOLOGY?

open access: yesZygon, 2015
In Insight, Bernard Lonergan provides, albeit schematically, a unique philosophy of biology which he takes as having “profound differences” with the world view presented by Darwin.

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 ...
