Differential development of umbilical and systemic arteries. I. ANG II receptor subtype expression

, 1998
In fetal sheep umbilical responses to angiotensin II (ANG II) exceed those by systemic vasculature. Two ANG II receptors (AT) exist, AT1 and AT2, but only AT1 mediates vasoconstriction in adult tissues.

Single‐Incision Laparoscopy‐First Strategy in Crohn's Disease: Risk Factors for Conversion and Surgical Outcomes

Annals of Gastroenterological Surgery, EarlyView.
In this retrospective study of 289 patients with Crohn's disease undergoing a single‐incision laparoscopy‐first (SILS‐first) strategy, conversion to open surgery was required in only 11.8% of cases. Fistula formation, colon resection, and smoking history were identified as independent risk factors for conversion, while postoperative complications and ...

Vasoactive Actions of Prostaglandins and Serotonin on Isolated Human Umbilical Arteries and Veins

, 1972
Cumulative responses to prostaglandins E1 (PGE1), E2 (PGE2), F1α(PGF1α), and F2α (PGF2α) were obtained on isolated human umbilical arteries and veins. All four prostaglandins produced contractions.

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 ...
