Prediction of birthweight by fetal ultrasound biometry

open access: yesThe British Journal of Radiology, 1994
The method of measurement of abdominal circumference (AC) is not stated in the paper by Nzeh et al [1]. It is known [2] that measurements based on derived values of AC, such as ellipse fitting or computation from two linear measurements, differ from measurements based on tracing around the outline, the latter being approximately 5% greater.

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...

Synergistic Microstructure and Dielectric Engineering of Recyclable Single‐Electrode Triboelectric Nanogenerators for Sustainable Smart Homes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A recyclable triboelectric nanogenerator integrating a pseudo‐honeycomb microstructure with liquid metal doping achieves 120% higher output (122 mW m−2) and >90% retention over seven cycles, enabling self‐powered smart home functions. The performance of single‐electrode triboelectric nanogenerators (SE‐TENGs) is governed by the effective contact area ...
