Contemporary and Historical Evidence to Suggest that Women’s Preference for Age at Birth of First Child Remains Consistent Across Time [PDF]
, 2014 Women’s ability to reproduce is restricted by menarche and menopause. First children are, however, not typically born until some years after the onset of puberty. Other factors therefore contribute towards this delay. In this context, women’s hips do not

Mononuclear Diploidy at the Heart of Cardiomyocyte Proliferation [PDF]
Cell Stem Cell, 2017 Reporting in Nature Genetics, Patterson et al. (2017) show that adult mammalian hearts possess an innate capacity to regenerate, which depends on a small population of mononuclear diploid cardiomyocytes. These cells undergo karyokinesis and cytokinesis, raising the possibility that endogenous cardiac muscle cells can be stimulated to proliferate for ...

Developmental Dynamics, Volume 254, Issue 11, Page 1203-1220, November 2025.Abstract Background While heart function is broadly conserved across vertebrates, the cellular phenotype of muscle cells (cardiomyocytes) varies across taxa and throughout ontogeny. Emerging evidence suggests that some attributes may correlate with the capacity for spontaneous cardiomyocyte replacement following injury.

Prenatal Diagnosis, Volume 45, Issue 12, Page 1559-1571, November 2025.ABSTRACT Objectives To estimate the residual risk of fetal chromosomal aberrations in pregnant women with normal cell‐free DNA (cfDNA) screening results to refine prenatal counseling. Methods A retrospective single‐center study was conducted between April‐2017 and March‐2021. In total, 46,007 women received a normal cfDNA screening result.

A SVM-Based Multi-Resolution Procedure for the Estimation of the DOAS of Interfering Signals in a Communication System [PDF]
, 2011 In this work, the use of a planar antenna system for the estimation of the directions of arrivals (DOAs) of multiple signals impinging on the receiver has been considered.

Somatic mutation favors the evolution of diploidy. [PDF]
Genetics, 1995 Abstract Explanation of diploidy have focused on advantages gained from masking deleterious mutations that are inherited. Recent theory has shown that these explanations are flawed. Indeed, we still lack any satisfactory explanation of diploidy in species that are asexual or that recombine only rarely. Here I consider a possibility first

Somatic chromosomal changes of rat liver cells during in vitro cultivation [PDF]
, 1971 In order to examine how long diploid cells can be maintained in vitro cultivation without any chromosomal aberrations and to evaluate the mechanism of chromosomal heteroploid transformation, changes of chromosomes were studied in the course of serial in ...

The concept of the sexual reproduction cycle and its evolutionary significance [PDF]
, 2015 The concept of a sexual reproduction cycle (SRC) was first proposed by Bai and Xu in 2013 to describe the integration of meiosis, sex differentiation and fertilization.
