Silk Transformed into Bactericidal Fabric
Scientists from the US Air Force Research Laboratory have found a way to convert ordinary silk into an antibacterial fabric by dipping it into certain chemicals. After the coating process the silk can kill bacteria and even coated spores. The research results were reported this week in ACS Applied Materials & Interfaces. Previous research showed [...]
Chondrogenic differentiation of human subchondral progenitor cells is affected by synovial fluid from donors with osteoarthritis or rheumatoid arthritis
Published: 13 March 2012 Background Microfracture is a first-line treatment option for cartilage repair. In microfracture, subchondral mesenchymal cortico-spongious progenitor cells (CSP) enter the defect and form cartilage repair tissue. The aim of our study was to investigate the effects of joint disease conditions on the in vitro chondrogenesis of human CSP. Methods CSP were [...]
‘Panic button’ could help cancer defy drugs
Stressed yeast cells frantically reshuffle their chromosomes in a desperate last bid to find a combination that survives. This “panic” response enables them to rapidly evolve resistance to drugs. The discovery might also apply to cancer, because cancer cells often have abnormal numbers and arrangements of chromosomes. Understanding one of the mechanisms by which cancers [...]
