Ovarian tissue transplant creates history


Share post:


An Australian woman, who was infertile, is now pregnant with twins after growing eggs in ovarian tissue that was transplanted into her abdomen – first time this type of treatment has taken place in the world.
A team at Melbourne IVF and The Royal Melbourne Hospital managed to help the woman, known just by her first name, Vali, grow egg follicles and produce two eggs by transplanting her own frozen ovarian tissue into her abdomen and stimulating it with a mild hormone treatment, the Sydney Morning Herald reported.
This is the first time that tissue has been successfully transplanted at a different site in the body to where it was harvested from.Vali’s fertility specialist, Kate Stern, said it has taken years and required daily testing and other procedures, to achieve the pregnancy. She said that she had to work closely with an oncologist to ensure that Vali’s ovarian tissue did not have cancer cells in it. (ANI)

No proof that football causes Alzheimer’s disease

A clinical neuropsy chologist has claimed to have found no credible scientific evidence that playing football may cause Alzheimer’s disease or other neurological disorders.Loyola University Medical Center clinical neuropsychologist Christopher Randolph, PhD, said that there is absolutely no credible scientific data to suggest an increase of neurological risk from playing professional football.Under the tentative settlement, the NFL would pay up to $5 million for each player who has Alzheimer’s disease and up to $4 million for each death from chronic traumatic encephalopathy (CTE). But a recent study by Randolph and colleagues of retired NFL football players found no evidence that CTE even exists.
They found that NFL players have overall mortality rates that are only half of expected rates based upon men in the general population. Suicide rates are only about 40 percent of the rates in the general population.
The study has been published in the Journal of the International Neuropsychological Society. (ANI)
