Intractable pain may find relief in tiny gold rods Scientists have developed a technique that could lead to therapies for pain relief in people with intractable pain, potentially including cancer-related pain. The team coated gold nanorods with a special type of protein that transports fat within the body known as a lipoprotein. This allowed the nanorods to bind efficiently to nerve cell membranes bearing a pain receptor. Gold nanorods are tiny rods that are 1-100 nanometers wide and long. In comparison, a human hair is 100,000 nanometers wide.
Something to chew on: Millions of lives blighted by smokeless tobacco More than a quarter of a million people die each year from using smokeless tobacco, researchers have concluded. The study estimates that in 2010 alone smokeless tobacco resulted in more than 62,000 deaths due to cancers of the mouth, pharynx and esophagus and accounted for more than 200,00 deaths from heart disease.
US hospitals flout CDC recommendations that prevent infections There is significant variability regarding how clinicians manage catheters placed in the arteries of patients in intensive care units, research shows. Some practices may increase risk of infection associated with these catheters. Fewer than half of those surveyed complied with current Centers for Disease Control and Prevention infection prevention guidelines for arterial catheter insertions.
