Stem cells have been considered as promising breakthrough as cancer treatments. Potential sources such as skin cells, bone marrow cells, etc., have been widely researched. It seems that there is addition to these sources as researchers from a biotechnology firm in Arizona discovered the endometrial regenerative cells.
Ethical issues have been raised regarding this new form of medical treatment.
Stem cells come from two main sources: embryos or adult tissues. Embryonic stem cells can give rise to virtually any cell type in the body, but they are controversial because conventional procedures for obtaining them involve the destruction of an embryo. Adult stem cells, such as those found in bone marrow, do not pose the same ethical concerns, but they have limited powers and collecting them can require invasive procedures.
While the new technique of reverting skin cells to an embryonic stem cell-like state promises to overcome the ethical dilemmas, this approach could come with safety concerns that make the cells too risky for use in humans. The technique for converting the skin cells involves using viruses to insert several genes, one of which is known to cause cancer.
Menstrual stem cells could turn out to be a happy medium between embryonic and adult stem cells, providing an ethically acceptable alternative that is readily accessible and appears to give rise to most of the major tissue types in the body.MSNBC

Philadelphia doctors say “yes!”
A new interesting treatment is being tested by Philadelphia doctors to restore life and bring people back from the dead.
A cardiac arrest patient was saved by the new experimental treatment of chilled saline injection. Cooling pads are then wrapped around a patient. The body temperature is normally 98 degrees, but cooling brings it down to 92 degrees. Doctors keep it there for about 24 hours. This process is called intentional hypothermia. Accordingly, it decreases cellular injury when the cells are deprived of oxygen, so with less injury we are able to do a better job of getting people back.
