A team of international researchers has transferred eye tissue from newborn to adult mice. It lets the blind adults detect light. The scientists say it challenges conventional wisdom on stem cells, because the successful cells had already stopped dividing before they were transferred.
Dr Margaret Chan of China was nominated by the Executive Board of the World Health Organization for the post of Director-General. The Director-General is WHO’s chief technical and administrative officer. Dr Chan is a well-known public figure because of her record of leadership in fighting disease first in Hong Kong, and more recently at WHO.
Researchers at the Cancer Treatment Centers of America found that antioxidant therapies such as green tea extract, melatonin, high-potency multivitamins, vitamin C and vitamin E do not interfere with radiation treatment.
The U.S. Food and Drug Administration (FDA) today announced its action plan for strengthening the way it monitors the safety of medical devices after they reach the marketplace.
Potentially blinding blood vessel growth in the cornea resulting from eye injury or even surgery can be reduced by more than 50 percent with a new manmade protein, researchers say.
A simple points system may soon help guide treatment of elderly heart failure patients. Researchers at Washington University School of Medicine in St. Louis found that by counting how many of seven easy-to-obtain health factors a patient has, physicians can estimate the patient’s risk of dying.
A new RNA map, created by a team of researchers at Rockefeller University and the Howard Hughes Medical Institute, shows for the first time how the specific location of short snippets of RNA affects the way that alternative splicing is controlled in the brain.
Minorities account for 30 percent of the U.S. population, but only eight percent of the physician workforce, and experience less personal satisfaction during medical school than nonminority students, finds a Mayo Clinic study published in the November issue of Mayo Clinic Proceedings.
Too much of a signaling protein called insulin-like growth factor-I (IGF-I) may fan the flames of cancer, while too little of the protein may cause short stature, dementia and osteoporosis. New research investigates how the growth hormone/IGF system is affected by the important tumor suppressor gene p53. This interplay of two signaling pathways reinforces questions about the long-term risks of prescribing growth hormone, while suggesting a future new avenue for cancer therapy.
Scientists in Australia have discovered that in acute lymphoblastic leukemia (ALL) there are “good” and “evil” clones of the same type of ALL cell. The “evil” cells are clones that have a pre-existing resistance to drugs used for treating ALL, and their presence in a patient means that person will inevitably relapse after chemotherapy, according to research presented at the 18th EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics.
