Evolving Lessons on Metazoan Primordial Germ Cells in Diversity and Development

open access: yesMolecular Reproduction and Development, Volume 92, Issue 5, May 2025.
ABSTRACT Germ cells are pivotal for the continuation of biological species. The metazoan germline develops from primordial germ cells (PGCs) that undergo multiple rounds of mitotic divisions. The PGCs are specified by either maternal inheritance of asymmetrically polarized cytoplasmic mRNAs/proteins (found in roundworms, flies, fishes, frogs, and fowl)

Effects of valproic acid on wound healing of the abdominal wall musculoaponeurotic layer: an experimental study in rats

open access: yesRevista do Colégio Brasileiro de Cirurgiões
Introduction: valproic acid (VPA), an epigenetic drug, has potential for the treatment of neoplasms. Its effects on the healing of the peritoneal-musculo-aponeurotic plane (PMA) of the abdominal wall are studied.

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.

The Lokve Barite Deposit, Croatia: an Example of Early Diagenetic Sedimentary Ore Deposits

open access: yesGeologia Croatica, 2010
Syngenesis versus epigenesis in the Kupferschiefer genetic model is still a matter of controversy. The title of the article seems to be a paraphrase of a well-known paper by WEDEPOHL (1971), “Kupferschiefer as a prototype of syngenetic sedimentary ...

Epigenetics: What it is about? [PDF]

open access: yes, 2014
Epigenetics has captured the attention of scientists in the past decades, yet its scope has been continuously changing. In this paper, we give an overview on how and why its definition has evolved and suggest several clarification on the concepts used in

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.

Thinking about the next generation: The case for a mentalization‐informed approach to perinatal and intergenerational mental health

open access: yesPsychology and Psychotherapy: Theory, Research and Practice, Volume 97, Issue S1, Page 1-15, November 2024.
Abstract Background There has been substantial progress made across multiple disciplines to emphasize the importance of perinatal mental health both for parents and offspring. This focuses on what has been termed the ‘First 1000 Days’ from conception to the child's second birthday.

Mechanisms For The Environmental Regulation Of Gene Expression: Ecological Aspects Of Animal Development [PDF]

open access: yes, 2005
The environment can play a significant role in the production of phenotypes. However, the developmental mechanisms by which the environmental agents effect normal development are Just becoming known. At least three paths have been found through which the
