WPI receives $1.6 million allocation for research on advanced implantable neuroprosthetics
WORCESTER, Mass. -- The conflicts in Iraq and Afghanistan have left a terrible legacy: more than 1,200 returning American soldiers have lost one or more limbs. To address this growing national need, researchers at Worcester Polytechnic Institute (WPI) are laying the groundwork for a new generation of advanced prosthetic limbs that will be fully integrated with the body and nervous system. These implantable neuroprosthetics will look and function like natural limbs, enabling injured soldiers and the more than 2 million other amputees in the United States lead higher quality, more independent lives.

Ovarian transplantation: First baby is born after a new technique
Amsterdam, The Netherlands: A new technique for transplanting the ovaries of women who have lost their fertility as a result of cancer treatment was outlined to the 25th annual conference of the European Society of Human Reproduction and Embryology today (Monday 29 June). Dr. Pascal Piver, manager of the IVF Centre at Limoges University Hospital, Limoges, France, described a new, two-step method of ovarian transplant that has produced excellent results in women whose ovaries have been frozen because of cancer treatment. He said that his team's technique worked to restore ovarian function quickly and already one patient from his clinic had had a baby and another had become pregnant.

Ovarian transplantation: New technique gives greatly improved results in this delicate operation

Dr. Sherman Silber, Director of the St. Louis Infertility Centre, St. Louis, Missouri, USA, said that freezing tissue by the vitrification method, which avoids ice formation, meant that oocyte (egg) viability was almost identical with that seen in fresh oocytes.
