Pharmalot submits: In a highly unusual move, a medical journal has devoted an entire issue to dissecting a mushrooming controversy over Infuse, a genetically engineered protein that is made by Medtronic (MDT) and has been widely used in spinal surgeries. But the Spine Journal reviewed 13 studies previously published elsewhere and discovered that side effects were downplayed or omitted.
Every two minutes someone in the UK has a heart attack. Every six minutes, someone dies from heart failure. During an attack, the heart remodels itself and dilates around the site of the injury to try to compensate, but these repairs are rarely effective. If the attack does not kill you, heart failure later frequently will.
Scientists on Friday raised questions about the safety of reprogramming adult cells, an experimental technique which supporters say could one day lead to the growing of replacement tissue in the lab.Certain kinds of these cells may be rejected by the immune system, which would thus doom them as an option for transplant, according to a study published online by the British science journal Nature.Interest in cellular reprogramming surged after researchers in 2007 announced they could wind back the DNA of adult, or mature, cells.
Scientists have pinpointed a molecular mechanism in mice which helps skin cancer cells confound the animal's immune system, according to a study released Wednesday.The discovery -- if duplicated in humans -- could one day lead to drug treatments that block this mechanism, and thus the cancer's growth, the study reported.In experiments on mice, researchers showed for the first time that a protein called interferon-gamma (IFN-gamma) plays a key role in the spread of melanoma, a notoriously aggressive form of cancer resistant to standard chemotherapy.
I share most if not all of Anil Dash’s nostalgia for the web we lost. Once upon a time, in the wake of the dot-com crash, there was a real feeling that the mammals would supplant the dinosaurs, and that the web would increasingly become a real network of individual sites, rather than being dominated by a handful of enormous portals. There were lots of companies working to that end, including Anil’s own company, Six Apart. And those companies cared deeply about empowering the mammals:
Rival underwear-makers Spanx and Yummie Tummie are butting heads, the latter claiming patent infringement, the former denouncing that claim as without merit. The dispute pits one diva against another: Heather Thomson, a former cast member of hit TV show Real Housewives of New York, founded Yummie Tummie in 2008, introducing the company's signature, shape-flattering 3-panel control top. Sara Blakely—youngest woman on Forbes' billionaires list—founded Spanx in 2000, introducing what Spanx calls a shaping camisole in 2005.
