Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

open access: yesAdvanced Science, EarlyView.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Blastulation and ploidy prediction using morphology assessment in 33,999 day-3 embryos

open access: yesScientific Reports
Although contemporary practice in in vitro fertilization (IVF) favors embryo transfer at blastocyst stage, several centres worldwide employ cleavage-stage Day-3 embryo transfers.

A review of migration and fertility theory through the lens of African immigrant fertility in France [PDF]

open access: yes
This paper evaluates fertility and migration theory in order to further understand the impact of migration on fertility. I first analyze the fertility and migration literature separately and then look at the burgeoning literature on the impact of ...

TED1 Promotes the Assembly of SCFD3‐D14‐D53 to Reinforce Strigolactone Signaling in Rice

open access: yesAdvanced Science, EarlyView.
This study identifies TED1 as a positive regulator of strigolactones (SL) signaling in rice. The ted1 mutants display dwarfism and increased tillering with significantly reduced SLs sensitivity. Through its longer C‐terminal region, TED1 interacts with D53 and D14 to promote the assembly of SCFD3‐D14‐D53, thereby facilitating the efficient ...

Close kin influences on fertility behavior [PDF]

open access: yes
Family members are uniquely situated to influence the decision-making of their kin in nearly every facet of life. We examine the importance of social interactions in fertility outcomes by assessing family members’ scope of influence on their fellow kin’s

Endothelial miR‐15a/16‐1 Regulation of SYNE1 Mediates Structural and Functional Recovery after Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
Endothelial miR‐15a/16‐1 deletion promotes long‐term recovery after traumatic brain injury by restoring SYNE1 expression. Enhanced endothelial SYNE1 preserves vascular integrity, protects white and gray matter, and improves neurological function. The endothelial miR‐15a/16‐1–SYNE1 axis emerges as a key regulator of neurovascular repair and a potential ...

Explaining Movements in Completed Fertility Across Cohorts [PDF]

open access: yes
A life cycle model of fertility based on the quantity-quality model of fertility successfully explains changes in completed fertility in a period in which completed fertility first fell and then rose. This model furthermore accurately predicts the timing

Orientation‐Engineered Insulator‐Metal Transition in Vanadium Dioxide

open access: yesAdvanced Science, EarlyView.
Crystallographic orientation engineering in VO2/TiO2 heterostructures enables tunable insulator‐metal transitions. The high‐Miller‐index (102) orientation breaks in‐plane mirror symmetry, inducing anisotropic transport, while its inclined oxygen channels accelerate protonation kinetics.

Why we measure period fertility

open access: yes, 2007
Four reasons for measuring period fertility are distinguished: to explain fertility time trends, to anticipate future fertility, to construct theoretical models and to communicate with non-specialist audiences.

Religious affiliation, religiosity, and male and female fertility [PDF]

open access: yes
Religious studies of fertility typically focus on the effect of religious affiliation on fertility; the role of religiosity in determining fertility remains overlooked.
