AI Article Synopsis

  • The authors examine the structure of myelinated and nonmyelinated nerve fibers in the human myometrium during late pregnancy.
  • The degenerative appearance of nerve endings is observed near muscular structures.
  • This structural change aligns with reduced levels of noradrenaline in the uterus, indicating a depletion of catecholamines at the end of pregnancy.

Article Abstract

The authors describe the ultrastructure of myelinated and nonmyelinated nerve fibres as seen in human myometrium at the end of pregnancy. The nerve ending looks degenerate and is found in close contact with a structure that is probably muscular. This ultrastructural appearance corresponds to the quantitative levels of noradrenaline found in the tissues at the end of pregnancy which show that the uterus becomes depleted of catecholamines.

Role of resistin in the porcine uterus: effects on endometrial steroidogenesis.

Reprod Fertil Dev

January 2025

Department of Animal Anatomy and Physiology, Faculty of Biology and Biotechnology, University of Warmia and Mazury in Olsztyn, Olsztyn, Poland.

Context The adipose tissue produces adipokines - hormones essential to many biological functions, including reproduction. Aims We hypothesised that resistin, one of the adipokines, is present in the blood plasma, uterine luminal flushings (ULF) and uterus of pigs during the oestrous cycle and early pregnancy, and that resistin influences uterine steroidogenesis. Methods This study aimed to determine the expression of resistin in the porcine endometrium and myometrium during the cycle and pregnancy by quantitative real-time polymerase chain reaction and western blot (WB).

Matrix Metallopeptidase 9 Promotes Contraction in Human Uterine Myometrium.

Reprod Sci

January 2025

Department of Pharmacology, University of Nevada, Reno School of Medicine, 1664 North Virginia St., Reno, NV, 89557, USA.

Matrix metallopeptidase 9 (MMP9) is a secreted zinc-dependent peptidase known for extracellular remodeling. MMP9 is elevated in tissues from women experiencing preterm labor, and previous research has shown that the addition of combined matrix metallopeptidases 2 and 9 (MMP2/9) enhances uterine contractions. We hypothesized that adding MMP9 alone would enhance myometrial contractions and that specific MMP9 inhibition would suppress uterine contractions.

Adenomyosis is a benign condition where ectopic endometrial glandular tissue is found within the uterine myometrium. Its impact on women's reproductive outcomes is substantial, primarily due to defective decidualization, impaired endometrial receptivity, and implantation failure. The exact pathogenesis of the disease remains unclear, and the role of autophagy in adenomyosis and its associated infertility is not well understood.

A case of large uterine cystic adenomyosis outside the uterus after laparoscopic myomectomy: a case report and literature review.

BMC Womens Health

January 2025

Department of Obstetrics and Gynecology, Shengjing Hospital of China Medical University, No.36 Sanhao Street, Heping District, Shenyang, Liaoning Province, 110004, China.

Background: Uterine cystic adenomyosis is a rare form of focal adenomyosis that is primarily located within the myometrium. In this case report, we present a unique case of adult uterine cystic adenomyosis found outside the uterus following laparoscopic myomectomy.

Case Presentation: The patient was a 36-year-old Chinese woman who had previously undergone laparoscopic surgery at our hospital to remove a 4 cm diameter diameter uterine fibroid six years prior.

Article Synopsis
  • Mesothelial cysts in the uterus are extremely rare; a 41-year-old woman experienced abdominal pain and imaging revealed a cystic mass in her uterus.
  • The patient underwent laparoscopic surgery, where a 7 cm cystic lesion was found in the uterine wall.
  • Pathological tests confirmed it was a mesothelial cyst, emphasizing that these cysts can resemble other conditions and are best diagnosed through surgical removal and examination.
