When U-M scientists transplanted windpipes in one type of mouse into the other, genetic variations between the two strains of mice triggered transplant rejection, inflammation and significant narrowing of the airway in the transplant recipients. But U-M researchers found out they could rescue the mice by having them inhale CO-enriched air for two weeks after transplantation, or giving them a drug that induces high levels of Hmox expression. We discovered that naturally occurring degrees of the Hmox enzyme were not high enough to avoid airway occlusion in mice after transplant, says Hiroaki Harada, M.D., a U-M study fellow and co-first writer of the scholarly study. We’d to either use medicines to improve Hmox expression in the mice or boost its end-item with prolonged inhalation of carbon monoxide.The butterfly experiment is definitely sponsored in part by the National Space Biomedical Research Institute located in Houston and is being conducted in collaboration with several non-profit educational organizations. Participating students and the public can view the butterfly images online at a science support and teacher teaching site of the Baylor University of Medicine’s Center for Education Outreach, which developed the curriculum instruction for teachers and Site support. The butterfly pictures from ISS also will be available at the Monarch View Web site, an educational and analysis group in the University of Kansas, which supplied the monarch butterflies.
