High Diagnosis Rate for Nonimmune Hydrops Fetalis With Prenatal Clinical Genome: Expanded Results From the Hydrops‐Yielding Diagnostic Results of Prenatal Sequencing (HYDROPS) Study

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nonimmune hydrops fetalis (NIHF) is characterized by abnormal fluid accumulation in ≥ 2 fetal compartments and may be genetic. The incremental diagnostic yield of prenatal exome sequencing (ES) for NIHF following a negative standard workup was previously explored on 22 cases.

A Comprehensive In Vitro Approach for Assessing the Physiological Degradation of Medical Implants: The Silkothane Arteriovenous Graft Case Study

Advanced NanoBiomed Research, EarlyView.
Evaluating the degradation of absorbable medical devices in vitro demands physiologically relevant conditions. This study presents a comprehensive framework applied to a three‐layered silk fibroin/polyurethane arteriovenous graft, employing human enzymes at physiological concentrations over 6 months. Multiparametric analyses of both graft structure and
