Identification of progressors in osteoarthritis by combining biochemical and MRI-based markers

A combination of biochemical and MRI markers will allow improved measurement of osteoarthritis (OA) progression. The biomarkers, described in BioMed Central's open access journal Arthritis Research and Therapy, will be useful for the design and interpretation of trials of new disease modifying drugs.

Scientists develop microfabricated device to measure cellular forces during tissue development

A University of Pennsylvania-led collaboration of bioengineers studying the physical forces generated by individual cells has created a tiny micron-sized device that allows researchers to measure and manipulate cellular forces as assemblies of living cells reorganize themselves into tissues.

New drug for muscle degenerating diseases shows great promise

A new drug being studied for the treatment of muscle degenerating diseases has shown promising results. According to a study published today in the British Journal of Pharmacology, Debio 025 is as effective as current drugs but, crucially, does not cause unwanted immunosuppressive effects.

People with Down syndrome may have more cancer-protective genes

Most cancers are rare in people with Down syndrome, whose overall cancer mortality is below 10 percent of that in the general population. Since they have an extra copy of chromosome 21, it's been proposed that people with Down syndrome may be getting an extra dose of one or more cancer-protective genes.

Automated tissue engineering on demand

Skin from a factory - this has long been the dream of pharmacologists, chemists and doctors. Research has an urgent need for large quantities of 'skin models', which can be used to determine if products such as creams and soaps, cleaning agents, medicines and adhesive bandages are compatible with skin, or if they instead will lead to irritation or allergic reactions for the consumer. Such test results are seen as more meaningful than those from animal experiments, and can even make such experiments largely superfluous.

Urine proteome pattern may predict coronary artery disease

Proteome analysis, a screening requiring only a patient's urine specimen, shows promise as a reliable and noninvasive way to diagnose atherosclerosis and coronary artery disease in the future, according to research presented at the American Heart Association's Arteriosclerosis, Thrombosis and Vascular Biology Annual Conference 2009.

Antioxidant ellagic acid prevents UV skin damage that leads to wrinkles

Using a topical application of the antioxidant ellagic acid, researchers at Hallym University in the Republic of Korea markedly prevented collagen destruction and inflammatory response - major causes of wrinkles -- in both human skin cells and the sensitive skin of hairless mice following continuing exposure to UV-B, the sun's skin-damaging ultraviolet radioactive rays.

Scientists first evidence of cell-to-cell communication by amino acids

A team of researchers from the Massachusetts General Hospital Center for Engineering in Medicine (MGH-CEM) has found the first evidence of cell-to-cell communication by amino acids, the building blocks of proteins, rather than by known protein signaling agents such as growth factors or cytokines.
