Vaginal pessary sharpens uterocervical angle in uterine prolapse during pregnancy. A case report.

A 37-year-old multiparous woman complained of uterine prolapse at 14 weeks of gestation. A silicone ring-shaped middle-size vaginal pessary (# 62 mm) was placed into the vagina to reduce prolapsed uterus. Because the cervical length became shortened at 25 weeks of gestation, we decided to start intramuscular administration of progesterone (250 mg) weekly.

Pentosidine accumulation in human oocytes and their correlation to age-related apoptosis.

Age-related atresia of ovarian follicles is characterized by apoptosis of the constituent cells. Recent studies have indicated that dysfunction of the proteasome and endoplasmic reticulum and subsequent apoptosis in the presence of oxidative stress have relevance to aging. The aim of this study was to assess the involvement of these processes in age-related follicular atresia.
