The utilization of c-type natriuretic peptide levels on experimental muscle and kidney ischemia/reperfusion model.

Introduction: C-type Natriuretic Peptide (CNP) is the third natriuretic peptide (NP) identified from the nervous system and endothelial cells. CNP is believed to be produced locally in tubular cells and glomeruli of kidneys. We aim to determine the clinical value of CNP levels at lower extremity muscle ischemia/reperfusion (I/R), kidney I/R, and both I/R models and evaluate them in laboratory practices.

Peripartum Hysterectomy: Is There Any Difference Between Emergency and Planned Surgeries?

Objective:  To compare the outcomes of emergency and planned peripartum hysterectomies.

Methods:  The present retrospective cross-sectional study was conducted in two hospitals. Maternal and neonatal outcomes were compared according to emergency and planned peripartum hysterectomies.

A rare case of the new entity of müllerian anomalies mimicking the noncommunicating rudimentary cavity with hemi-uterus: accessory cavitated uterine mass.

Objective: To demonstrate the laparoscopic excision of an accessory cavitated uterine mass (ACUM) and show that atypical anomalies can lead to the misdiagnosis of a noncommunicating rudimentary horn.

Design: Description and step-by-step demonstration of the surgical procedure using a video recording (Canadian Task Force Classification 3).

Setting: University hospital.

Serum progesterone level above 0.85 ng/mL and progesterone/estradiol ratio may be useful predictors for replacing cleavage-stage with blastocyst-stage embryo transfer in fresh IVF/ICSI cycles without premature progesterone elevation.

Purpose: To assess the impact of serum progesterone level and the progesterone/estradiol ratio on determining the appropriate day of embryo transfer in fresh IVF/ICSI cycles without premature progesterone elevation.

Methods: This was a retrospective cohort study in a university teaching hospital. Only fresh embryo transfer cycles in the GnRH-antagonist protocol without elevated trigger-day progesterone levels (n = 508) were analyzed after taking into consideration the exclusion criteria.

Intrauterine insemination with ovarian stimulation is a successful step prior to assisted reproductive technology for couples with unexplained infertility.

The present retrospective cohort study analysed data of couples with unexplained infertility who underwent two to three intrauterine insemination (IUI) cycles. The inclusion criteria were age 20-40 years, failure to conceive for at least two years of unprotected intercourse, ovulation, normal semen analysis, and tubal patency. Total of 578 IUI cycles of 286 couples with unexplained infertility were included in the final analyses.
