Sustainable Synaptic Device with Two‐Dimensional Ferroelectric Materials for Neuromorphic Computing

Advanced Science, EarlyView.
α‐In2Se3 based FeSFETs can be utilized as sustainable devices through polarization switching governed by both out‐of‐plane and in‐plane polarizations. Upon reaching a fatigued state, current annealing enabled by conductance modulation can significantly enhance the endurance of FeSFETs.

DNA methylation analysis

Swiss Medical Weekly, 2013
DNA methylation, the addition of a methyl group to cytosines and adenosines, regulates gene expression on a level that is usually referred to as epigenetic, that is, stably maintained during cell divisions.

Trained Memory of Uterine Macrophages Improves Subsequent Pregnancy Outcomes

Advanced Science, EarlyView.
This study identifies that pregnancy imprints a durable, pregnancy‐specific form of trained immune memory in uterine macrophages, marked by the emergence of LILRB3+/PIR‐B+ cells that expand across gestations, acquire a tolerogenic and metabolically rewired phenotype, and actively protect against inflammatory pregnancy loss in mice.

Helicalization of Covalent Organic Framework Nanofibers with Amplified Spin Polarizability for Boosting Photocatalytic Hydrogen Evolution

Advanced Science, EarlyView.
A non‐covalent chirality‐induced strategy via chiral solvents is presented to synthesize helical 2D COF nanofibers with high crystallinity, high chirality, and high spin polarization. The helical structure enhances the concentration of photogenerated charges, suppresses exciton recombination, and extends carrier lifetimes, thereby significantly ...

A case of an Angelman-syndrome caused by an intragenic duplication of UBE3A uncovered by adaptive nanopore sequencing

Clinical Epigenetics
Adaptive nanopore sequencing as a diagnostic method for imprinting disorders and episignature analysis revealed an intragenic duplication of Exon 6 and 7 in UBE3A (NM_000462.5) in a patient with relatively mild Angelman-like syndrome.

Possibilities and Limitations of Prenatal Diagnosis of Rare Imprinting Syndromes: Prader–Willi Syndrome

Children
Background: Prader–Willi syndrome (PWS) is a multisystemic complex imprinting disorder. Prenatal diagnosis of PWS is still a challenge with non-specific ultrasound markers and limitations for diagnosis with non-invasive screening methods.

Genome-wide analysis reveals a complex pattern of genomic imprinting in mice.

PLoS Genetics, 2008
Parent-of-origin-dependent gene expression resulting from genomic imprinting plays an important role in modulating complex traits ranging from developmental processes to cognitive abilities and associated disorders.

Genomic imprinting disorders in humans: a mini-review [PDF]

Journal of Assisted Reproduction and Genetics, 2009
Mammals inherit two complete sets of chromosomes, one from the father and one from the mother, and most autosomal genes are expressed from both maternal and paternal alleles. Imprinted genes show expression from only one member of the gene pair (allele) and their expression are determined by the parent during production of the gametes.

The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos

Advanced Science, EarlyView.
Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...

Mosaic genome-wide maternal isodiploidy: an extreme form of imprinting disorder presenting as prenatal diagnostic challenge

Clinical Epigenetics, 2017
Background Uniparental disomy of certain chromosomes are associated with a group of well-known genetic syndromes referred to as imprinting disorders. However, the extreme form of uniparental disomy affecting the whole genome is usually not compatible ...
