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 ...

Isovolumic relaxation strain imaging is an accurate and sensitive approach for detection of active diastolic dysfunction: A preclinical study

Animal Models and Experimental Medicine, EarlyView.
A modified approach was developed to accurately identify the isovolumetric relaxation time (IVRT) using an apical three‐chamber view. Compared with conventional echocardiography, isovolumic relaxation strain imaging (IVSI) helps to detect the earlier alternations of diastolic function in transverse aortic constriction (TAC) mice.

Optimization and verification of high‐fat diet formulation for establishing a rat model of obesity‐related precocious puberty

Animal Models and Experimental Medicine, EarlyView.
We identified 45% HFD as the optimal formulation to establish a juvenile rat model of obesity‐related precocious puberty. It elicits robust phenotypic (early vaginal opening, obesity), histological (advanced ovarian development), and endocrine (elevated HPG axis hormones) alterations, with leptin‐mediated GnRH secretion as a core mechanistic driver ...

Wireless blood pressure sensor implantation in sheep: A detailed technique

Animal Models and Experimental Medicine, EarlyView.
Twelve adult sheep underwent wireless blood pressure sensor implantation. The procedure lasted an average of 36 min, with mean systolic and diastolic blood pressures of 93 ± 6 and 65 ± 5 mmHg, respectively. This rapid, minimally invasive protocol is a powerful platform for cardiovascular device development.

Animal models of chronic thromboembolic pulmonary hypertension

Animal Models and Experimental Medicine, EarlyView.
Current animal models of CTEPH. Created using BioRender.com. Abstract Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare, yet life‐threatening disorder characterized by persistent pulmonary vascular obstruction and elevated pulmonary artery pressure, with progressive remodeling and subsequent right heart failure.
