background: estrogens include estoril (e3), estradiol and estrone (e1). these chemicals are produced in human and animal bodies as well as in synthetic chemicals (drugs). estrogens can enter water sources in different ways. when these chemicals enter the human body through water and wastewater, they have the ability to mimic or disrupt the normal estrogen activities in humans and animals. estro...
Prostaglandin (PG) F-2\g=a\is involved in a number of reproductive functions, including luteolysis (Goding, 1974) and menstruation (Pickles, Hall, Best & Smith, 1965). Luteolysis in sheep is controlled by a local feedback loop operating between the uterus and the corpus luteum, and menstruation in primates is also directly controlled by the ovarian steroid hormones. A fuller knowledge of how th...
Transplantation of cryopreserved intact ovaries from cancer patients is a technically challenging option for restoring fertility after sterilizing cancer therapy. In this paper we describe an assay based on 17ß-oestradiol (oestradiol) production, to monitor the functional damage sustained by the ovarian tissue during the freeze/thawing procedure. To this end, fresh bovine ovarian cortical biops...
The objectives of this research was to determine the chemical composition of roscoe extract from methanol and evaluation of antibacterial activity. The phytochemical compound screened by GC-MS method. Forty eight bioactive phytochemical compounds were identified in the methanolic extract of Zingiber officinale. The identification of phytochemical compounds is based on the peak area, retention t...
