CROI — Day 3: Selected highlights of NIH-supported research
The 18th Conference on Retroviruses and Opportunistic Infections is being held at the Hynes Convention Center in Boston from February 27 through March 2. Day three of this major HIV/AIDS research conference included the following selected present…
Scientists reveal new insights into tendon injury
Scientists have discovered how tendons — the fibrous tissue that connects muscle to bone — become damaged through injury or the ageing process in what could lead to new treatments for people with tendon problems.
The University of Manchester t…
How long do stem cells live?
LA JOLLA, Calif., March 1, 2011 — When patients receive a bone marrow transplant, they are getting a new population of hematopoietic stem cells. Fresh stem cells are needed when a patient is low on red blood cells, as in anemia, or white blood cel…
New induced stem cells may unmask cancer at earliest stage
MADISON – By coaxing healthy and diseased human bone marrow to become embryonic-like stem cells, a team of Wisconsin scientists has laid the groundwork for observing the onset of the blood cancer leukemia in the laboratory dish.
“This is the first…
Painful hip fractures strike breast cancer survivors
CHICAGO — A hip fracture is not common in a 54-year-old woman, unless she is a 54-year-old breast cancer survivor, according to a new Northwestern Medicine study. Researchers found that a combination of early menopause due to breast cancer treatme…
Researchers discover age of onset of puberty predicts adult osteoporosis risk
LOS ANGELES (January 27, 2011) — A team of researchers led by Vicente Gilsanz, MD, PhD, director of Clinical Imaging at The Saban Research Institute of Children’s Hospital Los Angeles, determined that the onset of puberty was the primary infl…
Colossal fossil: Museum’s new whale skeleton represents decades of research
ANN ARBOR, Mich.—There’s a whale of a new display at the University of Michigan Exhibit Museum of Natural History, a leviathan that represents a scientific saga of equally grand proportions.
A complete, 50-foot-long skeleton of the extinct whal…
Fleshing out the life histories of dead whales
Dead whales that sink down to the seafloor provide a feast for deep-sea animals that can last for years. Previous research suggested that such “whale falls” were homes for unique animals that lived nowhere else. However, after sinking five whale…
Jefferson study determines bone marrow stromal stem cells may aid in stroke recovery
PHILADELPHIA — A research study from the Farber Institute for Neurosciences and the Department of Neuroscience at Thomas Jefferson University determines bone marrow stromal stem cells may aid in stroke recovery. The results can be found in Cell T…
Monitoring wear in helicopters — and hips, knees and ankles, too
Tel Aviv — Ferrography, a practice used by the American and Israeli air forces to monitor the condition of machinery, extracts tiny iron particles from lubricants such as oil and grease to analyze wear in machines. Determining whether a syste…
New study into bladder regeneration heralds organ replacement treatment
Researchers in the United States have developed a medical model for regenerating bladders using stem cells harvested from a patient’s own bone marrow. The research, published in STEM CELLS, is especially relevant for paediatric patients suffering fro…
Hearing loss study reveals role of bone hardness in tissue function
Scientists are reporting the first direct evidence that a subtle change in the physical properties of a tissue can affect its function. The finding has immediate implications for understanding several rare hearing disorders, they said, and ultimatel…
Daily vibration may help aging bones stay healthy
AUGUSTA, Ga. – A daily dose of whole body vibration may help reduce the usual bone density loss that occurs with age, Medical College of Georgia researchers report.
Twelve weeks of daily, 30-minute sessions in 18-month old male mice — wh…
UMMS biomedical researchers develop more reliable, less expensive synthetic graft material
WORCESTER, Mass. — With a failure rate as high as 50 percent, bone tissue grafts pose a significant obstacle to orthopedic surgeons attempting to repair complex fractures or large areas of bone loss, such as those often caused by trauma and cancer…
Researchers engineer adult stem cells that do not age
Biomedical researchers at the University at Buffalo have engineered adult stem cells that scientists can grow continuously in culture, a discovery that could speed development of cost-effective treatments for diseases including heart disease, diabetes, immune [...]
New task force report on bisphosphonate use and atypical femur fractures in osteoporosis patients
Washington, DC, SEPTEMBER 14, 2010 — A widely prescribed class of drugs is highly effective in reducing common bone fractures in people with osteoporosis, but an expert panel announced today that these same drugs — when used long term — may be …
Physical environment influences stem cell development
Jerusalem — September 6, 2010 — A researcher at the Hebrew University of Jerusalem, together with Israeli and foreign collaborators, has revealed how physical qualities — and not only chemical ones — may have an influence in determining…
Faster method for growing adult stem cells for bone regeneration
A new method for utilizing adult stem cells for bone or other tissue regeneration without having to go through the intermediate step of expanding the number of cells in tissue culture has won a Kaye Innovation Award for a young doctoral student at the Hebrew University of Jerusalem. The Kaye Awards, now marking the tenth anniversary year of their inception, were presented on May 27 during the 66th meeting of the Hebrew University Board of Governors meeting in Jerusalem.
Bone loss possible after stomach reduction surgery
Women and men who have stomach reduction surgery to lose weight may be losing bone even when they take daily calcium supplements, putting them at risk for osteoporosis and bone fracture. These findings from a University of Pittsburgh study were presented Sunday in San Diego at the American Society of Nutritional Sciences program, part of the Experimental Biology 2003 meeting.
Bone marrow helps bones to repair themselves
Specially prepared titanium mesh and bone marrow cells have made it possible to allow new bone cells to grow in bone fractures. Researchers inserted a titanium mesh scaffold into a bone fracture in a rat. They allowed bone marrow cells to grow on this and the bone marrow cells stimulated new bone growth. In combination with bone marrow cells, titanium mesh forms a good culture medium for new bone growth in the case of bone damage. The researchers improved this bone growth by dynamically ‘sowing’ the cells onto the mesh.
