Adult stem cells improve healing of broken bones

Adult stem cells improve healing of broken bones and could eventually serve as a new treatment for the 10 to 20 percent of fractures that fail to heal, according to a new study. The results were presented Monday, June 16, at The Endocrine Society's 90th Annual Meeting in San Francisco, by Froilan Granero-Molto, PhD, research associate of the University of North Carolina.

Individualized therapies for non-Hodgkin's lymphoma identified with PET

Positron emission tomography (PET) could be an important tool for identifying non-Hodgkin's lymphoma patients who are likely to respond well to treatment with 90 ibritumomab tiuxetan (IT)-the first radioimmunotherapy treatment approved for use by the U.S. Food and Drug Administration, said researchers at the Society of Nuclear Medicine's 55th Annual Meeting.

Combined PET and CT could be valuable noninvasive tool for determining stages of ovarian cancer

Combined positron emission tomography (PET) and computed tomography (CT) scanning of patients in the early stages of ovarian cancer can enable physicians to determine whether the cancer has spread to nearby lymph nodes without having to perform surgery, according to researchers at the Society of Nuclear Medicine's 55th Annual Meeting.

Noninvasive molecular imaging technology helps track stem cells in tumors

Using noninvasive molecular imaging technology, a method has been developed to track the location and activity of mesenchymal stem cells (MSCs) in the tumors of living organisms, according to researchers at the Society of Nuclear Medicine's 55th Annual Meeting. This ability could lead to major advances in the use of stem cell therapies to treat cancer.

Aerobics increases blood protein that may suppress appetite

Three months of aerobic exercise decreased body fat and calorie intake in overweight and obese people, according to a new study, and the researchers believe that changes to a central nervous system factor are responsible. The results will be presented at The Endocrine Society's 90th Annual Meeting in San Francisco.
