Some studies have found that some concentrations of isoflavones may have effects on intestinal cells. At low doses, genistein acted as a weak estrogen and stimulated cell growth; at high doses, it inhibited proliferation and altered cell cycle dynamics. This biphasic response correlates with how genistein is thought to exert its effects. [47]
There is little modern clinical research on Dioscorea villosa, and the one study of a wild yam-containing cream for menopausal symptoms failed to find any value from this therapy. [18] According to the American Cancer Society , there is no evidence to support wild yam or diosgenin being either safe or effective in humans.
[8] [irrelevant citation] Wild yams are an important crop, as they have been used to prevent menstrual cramps, stomach cramps, and general pain for centuries. During the 1950s scientists found that the roots of wild yams contained diosgenin which is a plant-based estrogen; diosgenin is hypothesized to aid in chemical defense against herbivores.
Diosgenin, a phytosteroid sapogenin, is the product of hydrolysis by acids, strong bases, or enzymes of saponins, extracted from the tubers of Dioscorea wild yam species, such as the Kokoro. It is also present in smaller amounts in a number of other species.

The report also found the following: - 10 percent of vegetarian products contained meat; - Labels of some vegetarian products exaggerated the amount of protein in the item by as much as 2.5 times.
Vaginal cytology is a microscopic examination of cells from the vaginal epithelium.In veterinary medicine, it helps differentiate the stages of the mammalian estrous cycle because the vaginal epithelium changes in response to sex hormone levels; practically, it is used to distinguish when a female canine is at a particular point in the estrous cycle.

The seed yams are perishable and bulky to transport. Farmers who do not buy new seed yams usually set aside up to 30% of their harvest for planting the next year. Yam crops face pressure from a range of insect pests and fungal and viral diseases, as well as nematodes. Their growth and dormant phases correspond respectively to the wet season and ...
