Several companies have launched stem cell banks that offer collection and storage of stem cells -- including Cryo-Cell International's derivation of the cells from women's menstrual fluids and BioEden's baby teeth stem cell venture. The firms enumerate the diseases that may be treated in the future using the stem cells, but medical experts caution that the usefulness of such cells has yet to be established.
President George W. Bush on Monday commended the recent breakthrough in reprograming adult skin cells to act like embryonic stem cells and announced plans to expand government funding for "this type of ethical medical research." In his State of the Union address, Bush said the procedure "has the potential to move us beyond the divisive debates of the past by extending the frontiers of medicine without the destruction of human life."
The Iranian Blood Transfusion Organization has created a fibrin glue that takes the place of surgical stitches. The glue is created from a patient's blood plasma, reducing the chances of it being rejected by the immune system.
The FDA approved Voluven as a treatment to reduce and prevent blood loss during surgery. The intravenous solution, which expands the volume of blood plasma, proved safe and effective in clinical testing.
Small drops in body temperature can lead to increased surgical blood loss, according to a study. "When all the studies were evaluated together, the results clearly show that even very mild hypothermia increases blood loss and transfusion requirements by clinically important amounts," said the researcher in a statement.
