Scientists meet to discuss latest in how sex matters
...elopment By the time a tiny embryo attaches to the uterine
lining, it has already received important genetic instructions on how it will develop. If a male embryo is conceived, the genes provided by the maternal X chromosome are essential. Mutations on the X chromosome may lead to muscular dystrophy and in...
Study pinpoints mechanism behind tamoxifen side effect
...tamoxifen or raloxifene restrains their growth. In uterine
cells, estrogen and tamoxifen have the same growth-promoting effect, whereas raloxifene does not. The challenge for scientists has been to understand and explain these differences. Knowing why tamoxifen and raloxifene behave like estrogen in some cel...
UPCI presents study on estrogenic activity of medicinal botanicals
...to higher levels of estrogen, including breast and uterine
cancer. While plant extracts can alleviate symptoms for a variety of conditions, women should practice caution when using them and may want to avoid their use for conditions in which estrogens are contraindicated. Of the extracts studied, motherwort ...

cancer. Estrogen is also given to menopausal women to reduce the rate at which their bones become thinner and eventually break. "This is very valuable information that applies to a large spectrum of women in the United States, and we believe it will ...
Bone marrow cells may contribute to growth of new blood vessels in newborns
... later life, EPCs also are known to help build the uterine
wall during ovulation and to help repair damaged vessels during wound healing and recovery from ischemia. They also contribute to tumor growth. In neonates, however, new blood vessels are thought to grow only from pre-existing endothelial cells. "Th...
New device detects fetal brain response to light: May help prevent brain damage
.... Since SARA also can detect the fetal heartbeat, uterine
activity, and other physiological factors that may influence a healthy pregnancy outcome, it ultimately could be used in a variety of clinical tests, the researchers say....
Celebrex may be safe for preterm labor, preliminary study finds
...term delivery is indomethacin, a drug used to slow uterine
contractions and delay delivery. But indomethacin is associated with severe side effects. Recent research suggests that celecoxib, also known as celebrex, may be a safer alternative. This study is the first clinical trial testing celecoxib in pregnan...

protein, uteroferrin, identified by Bazer first in animals ultimately may be useful in treating diseases such as leukemia and osteoporosis in humans, according to the Wolf Prize jury. The award will be formally presented by Israeli President ...
Researchers discover how embryo attaches to the uterus
...s believe that as the blastocyst travels along the uterine
