On the multiple generations of planetary embryos [PDF]
, 2022 Global models of planet formation tend to begin with an initial set of planetary embryos for the sake simplicity. While this approach gives valuable insights on the evolution of the initial embryos, the initial distribution itself is a bold assumption.

International Journal of Reproductive BioMedicine, 2022 Background: Embryo quality may affect birth weight among neonates born through assisted reproductive technology. There are very limited studies assessing the adverse effect of transferring a poor-quality embryo with a good-quality one on neonatal ...

On the interaction of pebble accreting embryos with the gaseous disc: importance of thermal forces [PDF]
, 2023 A planetary embryo embedded in a gaseous disc can grow by pebble accretion while subjected to a gravitational force from the disc that changes its orbital elements. Usually, that force is considered to arise from the Lindblad and corotation resonances with the embryo. However, more important contributions exist for low-mass planets.

Eccentricity excitation and merging of planetary embryos heated by pebble accretion [PDF]
A&A 606, A114 (2017), 2017 Context: Planetary embryos can continue to grow by pebble accretion until they become giant planet cores. Simultaneously, these embryos mutually interact and also migrate due to torques arising from the protoplanetary disk. Aims: Our aim is to investigate how pebble accretion alters the orbital evolution of embryos undergoing the Type-I migration. In

The lady vanishes: what's missing from the stem cell debate [PDF]
, 2006 Most opponents of somatic cell nuclear transfer and embryonic stem cell technologies base their arguments on the twin assertions that the embryo is either a human being or a potential human being, and that it is wrong to destroy a human being or ...

BMC Pregnancy and Childbirth, 2023 Background There is ongoing debate regarding which embryo transfer procedure can achieve a higher live birth rate. Research has suggested that frozen ET might be beneficial for certain populations, such as hyper-responders.

Prepubertal Use of Long-Term GnRH Agonists in Dogs: Current Knowledge and Recommendations
Animals, 2022 The search for an alternative approach of estrus control (induction or suppression) in dogs is an important issue and the use of slow GnRH agonist-releasing implants has been the subject of frequent research in recent years.

Disappearing women, vanishing ladies and property in embryos [PDF]
, 2017 Guidelines on embryo storage prioritise 'respect for the embryo' above the wishes of the women whose labour and tissue have gone into creating the embryo in the first place, effectively making women and the female body disappear. In this article I draw a

Minimally invasive embryo transfer and embryo vitrification at the optimal embryo stage in rabbit model [PDF]
, 2019 [EN] Assisted reproductive techniques (ARTs), such as in vitro embryo culture or embryo cryopreservation, affect natural development patterns with perinatal and postnatal consequences.

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...
