Apoptosis in reproductive biology [PDF]
Cell Death & Differentiation, 1997 Recent studies aimed at a greater understanding of the occurrence and regulation of cell death in reproductive biology provide a promising new direction for novel approaches to understanding normal and pathological aspects of reproduction. Several instances of physiologically occurring cell death (programmed cell death, PCD), associated with ...

The genetic architecture underlying the evolution of a rare piscivorous life history form in brown trout after secondary contact and strong introgression [PDF]
, 2018 Identifying the genetic basis underlying phenotypic divergence and reproductive isolation is a longstanding problem in evolutionary biology. Genetic signals of adaptation and reproductive isolation are often confounded by a wide range of factors, such as

The Journal of Clinical Investigation, 2023 BACKGROUND Severe, early-onset fetal growth restriction (FGR) causes significant fetal and neonatal mortality and morbidity. Predicting the outcome of affected pregnancies at the time of diagnosis is difficult, thus preventing accurate patient counseling.

JCI Insight, 2021 Macrophages are commonly thought to contribute to the pathophysiology of preterm labor by amplifying inflammation — but a protective role has not previously been considered to our knowledge. We hypothesized that given their antiinflammatory capability in

Reproductive biology of Bellucia (MELASTOMATACEAE) [PDF]
Acta Amazonica, 1986 The reproductive biology of five of the seven species of Bellucia (Melastomataceae), a genus of shrubs and small trees, was investigated in Amazonia. Sucessful fruit-set by Bellucia requires floral visitation by bees.

Notes on the floral sexuality of some species of the tree genus Triplaris (Polygonaceae)
Caldasia, 2021 The majority of angiosperms (~94 %) are synoecious, with only a small minority separating the pro-duction of the two gamete types onto different biological individuals (dioecy).

ARRDC5 expression is conserved in mammalian testes and required for normal sperm morphogenesis
Nature Communications, 2023 In sexual reproduction, sperm contribute half the genomic material required for creation of offspring yet core molecular mechanisms essential for their formation are undefined.

A single-cell atlas of the myometrium in human parturition
JCI Insight, 2022 Parturition is a well-orchestrated process characterized by increased uterine contractility, cervical ripening, and activation of the chorioamniotic membranes; yet, the transition from a quiescent to a contractile myometrium heralds the onset of labor ...

Radiotherapy exposure directly damages the uterus and causes pregnancy loss
JCI Insight, 2023 Female cancer survivors are significantly more likely to experience infertility than the general population. It is well established that chemotherapy and radiotherapy can damage the ovary and compromise fertility, yet the ability of cancer treatments to ...
