Study shows antibiotic-resistant bacteria responsible for increase in muscle infections

...fections caused by Staphylococcus aureus have been treated by inexpensive antibiotics in the penicillin and cephalosporin family. Some years ago, strains resistant to these drugs, called methicillin-resistant Staphylococcus aureus (MRSA) appeared in hospitalized patients. Recently, however, newer forms of M...

Natural protein stops deadly human brain cancer in mice

... morphogenic protein 4 (BMP4), then injected these treated cells into mouse brains. In mice injected with cells that were not pretreated, large, invasive cancers grew. In the mice with BMP4-treated cells, no cancers grew at all. Three to four months after injection, all mice that got untreated cells died, an...
