Georgetown University Medical Center researcher Michael Zasloff, and colleagues first discovered squalamine nearly 2 decades ago while studying sharks in hopes of finding new, occurring antibiotic agents naturally. He explained that he chose sharks because they possess very primitive, but highly effective, immune systems. His newer research led to the discovery that the shark-derived compound works in a completely new way that could make it an effective antiviral medication, he said. The study appears on the web in the journal PNAS Early Edition. This consists of proteins that are important to viral replication.While much less invasive than medical procedures, the likelihood of potential aneurysm recurrence and subsequent treatment is usually higher with coiling. In order to lower the chance for do it again aneurysm treatment after coiling, Northwestern Medicine – experts are examining a fresh type of gel-covered coil to determine if it’s more effective compared to the regular bare coils in avoiding aneurysm recurrence. Aneurysms could be a very severe health threat, regarding to Bernard R. Bendok, MD, a neurosurgeon at Northwestern Memorial Medical center, who is the main investigator for the brand new era Hydrogel Endovascular Aneurysm Treatment Trial .
