Twin reversed arterial perfusion sequence-a rare and dangerous complication form of monochorionic twins: A case report.

Background: Twin reversed arterial perfusion (TRAP) sequence is an extremely rare congenital anomaly in monochorionic (MC) twins. The condition is characterized by a malformed fetus (acardiac twin) without cardiac activities being perfused by a structurally normal one (pump twin) an artery-to-artery anastomosis in a reverse direction.

Case Summary: We described the first case of TRAP to receive laser surgery in Vietnam.

Microwave-Assisted Synthesis of 5'--methacryloylcytidine Using the Immobilized Lipase Novozym 435.

Nucleobase building blocks have been demonstrated to be strong candidates when it comes to DNA/RNA-like materials by benefiting from hydrogen bond interactions as physical properties. Modifying at the 5' position is the simplest way to develop nucleobase-based structures by transesterification using the lipase Novozym 435. Herein, we describe the optimization of the lipase-catalyzed synthesis of the monomer 5'--methacryloylcytidine with the assistance of microwave irradiation.

Long-Term Follow-Up Of Anti-Mullerian Hormone Levels After Laparoscopic Endometrioma Cystectomy.

The study aims to evaluate long-term ovarian reserve change by serum anti-Mullerian hormone (AMH) level and determine the factors that affect the changes after laparoscopic endometrioma cystectomy. In a prospective longitudinal study, 104 patients with unilateral (n=77) and bilateral (n=27) endometrioma underwent laparoscopic endometrioma cystectomy. AMH levels were measured preoperatively and at 1, 3, 6, and 12 months postoperatively.

Dinoprostone Vaginal Insert for Induction of Labor in Women with Low-Risk Pregnancies: A Prospective Study.

Background: Induction of labor (IOL) is a technique to establish vaginal delivery when the risks for continuing the pregnancy for mother or baby are higher than the risks of delivery. It is usually performed in high-risk pregnancies, but can also be beneficial in low-risk populations, as shown in the ARRIVE trial.

Objective: To evaluate the effectiveness and safety of slow-release vaginal dinoprostone (prostaglandin E2 10 mg) for labor induction in women with low-risk pregnancies.

Retroperitoneal ectopic pregnancy after fertilization: A case report of a patient with bilateral salpingectomy.

Retroperitoneal ectopic pregnancy (REP) is a rare obstetric condition caused by the mislocalization of the gestational mass. The unexpected location often results in missed or delayed diagnoses, which can complicate the treatment process. We report the case of a 34-year-old Asian woman who presented to the hospital 31 days after embryo transfer with mild vaginal bleeding.
