In the past, bones were regenerated using sheep bones or synthetic materials which were costly and bio-hazardous. Recent studies have developed an eco-friendly material which is biodegradable and obtained from the waste products of the food industry. In particular, residue left over after brewing beer caught researchers’ eyes.
This study was conducted at Centre for Biomedical Technology of Universidad Politécnica de Madrid (UPM) and the Institute of Materials Science and the Institute of Catalysis and Petrochemistry of Consejo Superior de Investigaciones Científicas (CSIC). The results showed that the residue left after beer production was rich in contents like calcium, phosphorus, silica, etc. These were coincidently nutrients that help bones become stronger. The residue was incorporated to be used as a material in bone replacements as well as a coating in bone grafts. Not only does this material decrease the burden of the accumulated eco waste, it also provides nutrient-rich media for the treatment of bone diseases.
Nanomedicine technologies have advanced through the research done by Brigham and Women’s Hospital and Dana Farber Cancer Institute. The institute recently discovered a new drug delivery system that can attack cancer cells which are present bones. This system should increase bone strength as well as bone volume in order to control the growth of cancerous cells.
“Proceedings of the National Academy of Sciences” published last week discussed this nano technology. Bone is a very favorable place for cancer cells to grow and multiply in large numbers especially from certain parts of the body such as the breasts, prostate and blood. This nano particle system selectively targets the bones and releases the drug in a very subtle way, thus enhancing the growth and strength of the bone.
The National institute of Health and American College of Rheumatology have published a study that indicates walking will drastically reduce the risks of developing Osteoarthritis (OA) in people who have higher risks of getting it. Functional limitations like difficulty getting up from a chair and climbing stairs can be reduced significantly.
Many Americans aged just 25 years are now diagnosed as suffering from Osteoarthrits knees whereas earlier reports mentioned that OA knees is mostly common among middle-aged and older adults. Medical evidence reports that persons diagnosed with OA walk less than 90 minutes weekly on average. Walking is a common physical activity which can be performed daily by all adults. 80% of OA patients experience a limitation in their movements while 11% of adults have a disability to the extent that they need assistance with personal care.
