Congenital anomaly and perinatal outcome following blastocyst- vs cleavage-stage embryo transfer: systematic review and network meta-analysis. [PDF]

Ultrasound Obstet Gynecol, 2023
ABSTRACT Objectives To compare the reported rate of any congenital anomaly and perinatal outcome of pregnancy following blastocyst‐ vs cleavage‐stage embryo transfer using a pairwise meta‐analysis and to evaluate the same outcomes following fresh‐blastocyst, frozen‐blastocyst, fresh‐cleavage or frozen‐cleavage embryo transfer using a network meta ...

Identifying accurate pro-choice and pro-life identity labels in Spanish: Social media insights and implications for comparative survey research. [PDF]

Perspect Sex Reprod Health, 2022
Abstract Introduction Although debate remains about the saliency and relevance of pro‐choice and pro‐life labels (as abortion belief indicators), they have been consistently used for decades to broadly designate abortion identity. However, clear labels are less apparent in other languages (e.g., Spanish).

Embryo excision in Compositae, with implications for combating biodiversity loss. [PDF]

Appl Plant Sci
Abstract Premise Embryo excision is an effective, under‐described means of promoting germination in the sunflower family and may help to ensure the survival of endangered taxa or lineages with limited seed availability. Methods and Results We describe and illustrate a detailed method of embryo excision used successfully to stimulate germination in a ...

Fetal neurosonography and infant neurobehavior following conception by assisted reproductive technology with fresh or frozen embryo transfer. [PDF]

Ultrasound Obstet Gynecol, 2022
ABSTRACT Objective We aimed to explore fetal cortical brain development by neurosonography in fetuses conceived by assisted reproductive technology (ART), including frozen and fresh embryo transfer (ET), compared with those conceived spontaneously (SC), and to investigate its association with infant neurobehavior at 12 months of age. Methods This was a

Reproductive colonization of land by frogs: Embryos and larvae excrete urea to avoid ammonia toxicity

Ecology and Evolution, Volume 12, Issue 2, February 2022., 2022
Frogs have evolved terrestrial eggs many times, offering an excellent opportunity to assess traits that may facilitate aquatic‐to‐terrestrial transitions. Our results suggest the importance of physiological adaptations and physiological plasticity during early life stages, specifically the early onset of urea excretion, its upregulation under dry ...

Fetal movements: the origin of human behaviour

Developmental Medicine &Child Neurology, Volume 63, Issue 10, Page 1142-1148, October 2021., 2021
The study of the onset and ontogeny of human behaviour has made it clear that a multitude of fetal movement patterns are spontaneously generated, and that there is a close association between activity and the development of peripheral and central structures.

Ultrasound features in early pregnancy for predicting abnormal karyotype in first‐trimester miscarriage

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 376-384, March 2026.
ABSTRACT Objective To investigate whether combining abnormal morphological features observed on ultrasound in live pregnancies that ended in a first‐trimester miscarriage can predict an abnormal karyotype. Methods This retrospective observational cohort study was conducted at the early‐pregnancy assessment unit at University College London Hospital ...
