Differential expression of conserved germ line markers and delayed segregation of male and female primordial germ cells in a hermaphrodite, the leech helobdella. [PDF]

open access: yes, 2013
In sexually reproducing animals, primordial germ cells (PGCs) are often set aside early in embryogenesis, a strategy that minimizes the risk of genomic damage associated with replication and mitosis during the cell cycle.

Factors and mechanisms of productive secondary reservoirs formation in deep-lying oil and gas complexes. Article 1. Tectonophysical mechanisms of Lower Carboniferous quartzite-sandstones decompaction in the central part of the Dniprovsko-Donetska depression at the depths of more than 4.5 km

open access: yesМінеральні ресурси України
In the world, the scale of development of secondary reservoirs in decompaction rock bodies in a wide formation range is steadily increasing: from the crystalline basement of different ages of various oil and gas-bearing basins to terrigenous deposits ...

Developmental Systems Theory as a Process Theory [PDF]

open access: yes, 2018
Griffiths and Russell D. Gray (1994, 1997, 2001) have argued that the fundamental unit of analysis in developmental systems theory should be a process – the life cycle – and not a set of developmental resources and interactions between those resources ...

Social epigenetics: a science of social science? [PDF]

open access: yes, 2016
Epigenetics has considerable potential to transform social science by embedding mutually regulative reciprocal connections between biological and social processes within the human activities it studies. This paper highlights common epigenetic methods and

Kant's Metaphysics of Race, Its Distinctiveness, and Its Normativity

open access: yesJournal of Social Philosophy, EarlyView.
ABSTRACT Drawing on the contemporary taxonomy of the metaphysics of race, this paper shows that Kant's theory of race occupies a distinct metaphysical position on race. Second, it argues that Kant's metaphysics of race inherently produces racist claims.

Associations of Skin Biomechanical Properties With Biological Aging Clocks and Longitudinal Changes in Intrinsic Capacity in Adults Aged 20–93: The INSPIRE‐T Project

open access: yesAging Cell, Volume 24, Issue 10, October 2025.
This study assessed skin biomechanics using the Cutometer in 441 community‐dwelling adults aged 20–93 from the INSPIRE‐T cohort. We demonstrated that skin elasticity and viscoelasticity parameters were associated with the intrinsic capacity (IC) score, a functional marker of healthy aging encompassing cognition, locomotion, psychology, vitality, and ...

Better living through chemistry: caloric restriction (CR) and CR mimetics alter genome function to promote increased health and lifespan

open access: yesFrontiers in Genetics, 2016
Caloric restriction (CR), defined as decreased nutrient intake without causing malnutrition, has been documented to increase both health and lifespan across numerous organisms, including humans.

A Scoping Review of Neighborhood Effects and Health Among Children and Adolescents: Measurement and Design Characteristics

open access: yesJournal of Community Psychology, Volume 53, Issue 4, May 2025.
ABSTRACT Decades of research have explored how neighborhood conditions relate to child and adolescent health, spawning numerous reviews focused on specific predictors, outcomes, or populations. Less is known about the design and characteristics underpinning this work.

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.
