The Effect of Trans-Abdominal Chorionic Villus Sampling on Fetal Heart Rate and Placental Vascular Resistance Index: A Color Doppler Ultrasound Study

Acta Medica Iranica, 2021
Fetal hemodynamic changes can occur immediately following invasive chorionic villus sampling (CVS). We decided to study the possible effect of CVS on fetal heart rate (FHR), and uteroplacental resistance index (RI) changes using color Doppler ultrasound.

Building low-cost simulators for invasive ultrasound-guided procedures using the V-model

Advances in Simulation, 2023
The use of medical simulators for training technical and diagnostic skills has rapidly increased over the past decade. Yet, most available medical simulators have not been developed based on a structured evaluation of their intended uses but rather out ...

Prenatal treatment of mothers with fetuses at risk for congenital adrenal hyperplasia: How relevant is it to Indian context?

Indian Journal of Endocrinology and Metabolism, 2013
Management of congenital adrenal hyperplasia (CAH) from embryonic stage to adulthood is a critical challenge. We would like to comment on some of the practical difficulties in offering prenatal treatment for CAH-affected fetuses in Indian population. For

Investigating the presence of fetal trisomy 13, 18, and 21 in Pakistani Patients and its' Computational Analysis

International Journal of Endorsing Health Science Research, 2022
Background: Chromosomal aneuploidy due to meiotic non-disjunction is among the most significant and common causes of miscarriages in humans. The present study was conducted to investigate the presence of fetal trisomy 13, 18, and 21 in Pakistani ...

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

American 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 ...

Bridging maternal effects and epitranscriptomics: A novel perspective in developmental biology

Developmental Dynamics, EarlyView.
Abstract Maternal effects, encompassing both genetic (maternally expressed gene products) and non‐genetic (maternal state) influences, are powerful determinants of offspring phenotype, yet their RNA‐level mechanisms remain incompletely resolved. In parallel, epitranscriptomics, an emerging field centered on chemical modifications to RNA, has revealed ...
