High-fidelity quantitative differential phase contrast deconvolution using dark-field sparse prior [PDF]

arXiv, 2022
Differential phase contrast (DPC) imaging plays an important role in the family of quantitative phase measurement. However, the reconstruction algorithm for quantitative DPC (qDPC) imaging is not yet optimized, as it does not incorporate the inborn properties of qDPC imaging.

Insights on Advances in 3D Bioprinting for Peripheral Nerve Regeneration

Advanced Therapeutics, EarlyView.
Peripheral nerve injury is a common condition due to trauma that significantly impacts the life of the affected individual. This review explores the anatomy, classification, and pathophysiology of peripheral nerve injuries. It also discusses various types of nerve conduits and presents a detailed review of 3D bioprinted nerve conduits used in both in ...

Further characterization of NFIB‐associated phenotypes: Report of two new individuals

American Journal of Medical Genetics Part A, Volume 191, Issue 2, Page 540-545, February 2023., 2023
Abstract Nuclear Factor I B (NFIB) haploinsufficiency has recently been identified as a cause of intellectual disability (ID) and macrocephaly. Here we report on two new individuals carrying a microdeletion in the chromosomal region 9p23‐p22.3 containing NFIB.

PKU and COVID19: How the pandemic changed metabolic control

Molecular Genetics and Metabolism Reports, 2021
Background: COVID19 pandemic urged the need to take severe measures for reducing the epidemic spread. Lockdowns were imposed throughout countries and even Inborn errors of metabolism (IEMs) affected patients had to face it and adapt, with management ...

Pupil-driven quantitative differential phase contrast imaging [PDF]

arXiv, 2023
In this research, we reveal the inborn but hitherto ignored properties of quantitative differential phase contrast (qDPC) imaging: the phase transfer function being an edge detection filter. Inspired by this, we highlighted the duality of qDPC between optics and pattern recognition, and propose a simple and effective qDPC reconstruction algorithm ...

Asymmetric Inter‐Hemisphere Communication Contributes to Speech Acquisition of Toddlers with Cochlear Implants

Advanced Science, EarlyView.
The present study constructs machine‐learning models to resolve developmental relationships among auditory performance, auditory cortical processing, and functional connectivity of the bilateral language network during the first year of restored hearing. The results demonstrate that asymmetric inter‐hemisphere communication contributes significantly to

Biallelic GTF2IRD1 variants in brothers with profound neurodevelopmental disorder: A possible novel disorder involving a critical gene for Williams syndrome

American Journal of Medical Genetics Part A, Volume 191, Issue 2, Page 332-337, February 2023., 2023
Abstract GTF2IRD1, a gene on chromosome 7 which encodes a transcription factor, is of significant clinical interest due to its heterozygous loss as part of the classical deletion associated with Williams–Beuren syndrome (WBS). However, biallelic variants in GTF2IRD1 alone as part of an autosomal recessive disease have not been previously reported. Here,

Bulk topological insulators as inborn spintronics detectors [PDF]

Phys. Rev. Lett. 113, 196601 (2014), 2013
Detection and manipulation of electrons' spins are key prerequisites for spin-based electronics or spintronics. This is usually achieved by contacting ferromagnets with metals or semiconductors, in which the relaxation of spins due to spin-orbit coupling limits both the efficiency and the length scale.

Neural Plasticity and Hearing‐Speech Development in Children with Auditory Brainstem Implants for Congenital Hearing Loss Due to Severe Inner Ear Malformation

Advanced Science, EarlyView.
Data from a prospective cohort with 112 auditory brainstem implant users are analyzed. Younger age at implantation (<3 years), less severe inner‐ear malformation (common cavity, cochlear aplasia, and hypoplasia), and more intraoperative eABR evoked electrodes (≥60%) are associated with better hearing and speech outcomes.

Copy number variants suggest different molecular pathways for the pathogenesis of bladder exstrophy

American Journal of Medical Genetics Part A, Volume 191, Issue 2, Page 378-390, February 2023., 2023
Abstract Bladder exstrophy is a rare congenital malformation leaving the urinary bladder open in the midline of the abdomen at birth. There is a clear genetic background with chromosome aberrations, but so far, no consistent findings apart from 22q11‐duplications detected in about 2%–3% of all patients.
