Unraveling Neurodevelopment: Synergistic Effects of Intrinsic Genetic Programs and Extrinsic Environmental Cues

open access: yesAdvanced Science, EarlyView.
Overview of the regulation of intrinsic and extrinsic signals during neurodevelopment. Intrinsic genetic signals from NSCs, in conjunction with cues from microglia and blood vessels, collaboratively regulate the proliferation of NSCs, their fate determination, synaptogenesis, synaptic pruning, neuronal survival, and death, as well as communication ...

Placental RTN3L‐dependent ER‐Phagy Contributes to Fetal Testicular Dysplasia Upon Environmental Stress

open access: yesAdvanced Science, EarlyView.
Gestational environmental stress activates ER‐phagy by increasing placental Rtn3l mRNA N6‐methyladenosine modification, further inhibiting placental estradiol synthesis and contributing to fetal testicular dysplasia. This study demonstrates the early prevention and treatment of adult male infertility from the perspective of fetal‐derived diseases ...

Facial Anatomical Landmark Detection using Regularized Transfer Learning with Application to Fetal Alcohol Syndrome Recognition [PDF]

open access: yesarXiv, 2021
Fetal alcohol syndrome (FAS) caused by prenatal alcohol exposure can result in a series of cranio-facial anomalies, and behavioral and neurocognitive problems. Current diagnosis of FAS is typically done by identifying a set of facial characteristics, which are often obtained by manual examination.

An exploration of the potential utility of fetal cardiovascular MRI as an adjunct to fetal echocardiography [PDF]

open access: yes, 2016
Objectives: Fetal cardiovascular magnetic resonance imaging (MRI) offers a potential alternative to echocardiography, although in practice, its use has been limited. We sought to explore the need for additional imaging in a tertiary fetal cardiology unit

Prenatal detection and molecular cytogenetic characterization of 19q13.42 microduplication: three reported cases and literature review

open access: yesMolecular Cytogenetics, 2021
Background Trisomy 19q is a recognizable syndrome and associated with a wide spectrum of clinical phenotypes in clinic. The purpose of this study was to explore the prenatal phenotypes of 19q13.42 duplication, which was rarely reported in clinic.

Quantifying Residual Motion Artifacts in Fetal fMRI Data [PDF]

open access: yesarXiv, 2020
Fetal functional Magnetic Resonance Imaging (fMRI) has emerged as a powerful tool for investigating brain development in utero, holding promise for generating developmental disease biomarkers and supporting prenatal diagnosis. However, to date its clinical applications have been limited by unpredictable fetal and maternal motion during image ...
