One of Mother Nature's latest gifts to medical science is stirring excitement with the discovery that the substance "” obtained from a coral-reef inhabiting cyanobacterium "” appears to be an ideal blueprint for developing new drugs for serious fractures, osteoporosis, and other bone diseases. That's the conclusion of a study on the substance, Largazole, in the journal ACS Medicinal Chemistry Letters. By some estimates, more than half of today's medications are in Largazole's...

Singapore, Jan 31, 2011 - (ACN Newswire) - At KK Women's and Children's Hospital (KKH), a five-year old girl with severe curvature of the spine was among the first in Southeast Asia to have a "titanium rib" implant. Also known as the Vertical Expandable Prosthetic Titanium Rib (VEPTR), the adjustable titanium rib is designed to treat Thoracic Insufficiency Syndrome in skeletally immature patients. Thoracic Insufficiency Syndrome refers to the chest's inability to support normal growth of the...

Later puberty results in lower bone mass and increases risk of fracture 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 influence on adult bone mineral density, or bone strength. Length of puberty did not affect bone density. Reduced bone mineral density leads to osteoporosis, resulting in bones becoming increasingly brittle and at risk...

A team of researchers at Columbia Engineering and Columbia University Medical Center announced today the results of the first study comparing bone structure in Chinese-American women to Caucasian women. The report, just presented at the Orthopaedic Research Society's annual meeting at Long Beach, CA, found that pre-menopausal Chinese-American women have far greater bone strength than their Caucasian counterparts, as determined by a breakthrough technological advance. The Columbia team was led...

FRAX, a new tool for estimating a person's risk of fractures and bone breaks is in use by physicians at Summit Medical Group (SMG). Berkeley Heights, NJ (Vocus/PRWEB) January 13, 2011 FRAX, a new tool for estimating a person's risk of fractures and bone breaks is in use by physicians at Summit Medical Group (SMG). "As adults age, we lose bone mass, which can make bones fragile and prone to fracture and breaks," notes Robert L. Rosenbaum, M.D., SMG endocrinologist. One of the more serious...

In this paper, Noriyuki Tsumaki and his team at the Osaka University Graduate School of Medicine, used fibroblasts isolated from adult mouse skin, and expressed proteins used to induce pluripotency along with a factor that promotes a chondrocyte fate. The resulting cells resembled chondrocytes and produced cartilage when injected into mice. This may be an important step toward a therapy that will allow the repair of cartilage injury using a patient's own skin cells. Hyaline cartilage,...

Treating fractures in children requires special knowledge of growth physiology. Incorrect treatment of bone fractures in child and adolescent patients is less often caused by technical deficiencies than by a misjudgment of the special conditions in this age group. Using the example of treating fractures of the upper limb, Ralf Kraus from the Marburg-Gießen University Medical Center, and Lucas Wessel, University Medical Center Mannheim, report in the current issue of...

The adult human skeleton undergoes constant remodeling, with new bone forming at sites that have been broken down by a precise process called resorption. During remodeling, skeletal stem cells are recruited to resorption sites and directed to differentiate into bone-forming cells. Osteoporosis, a condition characterized by weak and fragile bones, develops when there is an imbalance in the remodeling process and more bone is lost than replaced. Now, new research published by Cell Press in the...

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 "“ which equate to 55- to 65-year-old humans "“ appear to forestall the expected annual loss that can result in fractures, disability and death. Dr. Karl H. Wenger, biomedical engineer in the MCG Schools of Graduate Studies and Medicine, reported the findings with...
