One Death Linked to Device

1 ShoulderFlex Massager Can Be Deadly

The ShoulderFlex Massager is so dangerous the FDA is recommending disposing of the device components separately so that it can't be reassembled and used. At least one death and a near-strangulation have been blamed on the device, manufactured by King International of Beaverton, Oregon. The two incidents occurred when a necklace and a piece of clothing became caught in the rotating component of the device. The FDA says that in other cases people's hair became caught in the device. The ShoulderFlex Massager was sold in retail stores and websites in the U.S. beginning in October 2003. MSNBC reports that the deadly device was still available for sale on Friday at amazon.com and other websites with a price of around $140.

2 Mechanism of T Cell Activation Discovered

New research has found that when T-cells bind to infected cells through receptors, a pathway is activated which allows calcium ions to flow into the specialized white blood cell that matures in the thymus. This influx of calcium ions changes it into an effector T-cell which is capable of killing the infected cell and replicating so other cells infected with the same pathogen can be killed. Studies in mice showed that knocking out the specific calcium gene dramatically lowered the immune system’s function and impaired its activation through the T-cell receptor. Drugs could be designed in two ways; ones that activate the pathway to fight HIV and cancer and ones that inhibit it to prevent transplant rejection and protect normal tissues in individuals with autoimmune diseases.
