FDA analyses finds ground castor beans - not purified ricin -- in two tampered baby food jars in Irvine, California case
Contrary to the impression given by some early reports, FDA did NOT find purified ricin in two baby food jars involved in an apparent tampering case in the Irvine, California area. To date no injuries have been reported, and these problems seem to be isolated within the immediate Irvine area.  more

Information for patients: Food tampering an extra ounce of caution
The deliberate tampering of food to cause major disease outbreaks is rare, particularly in the United States. However, recent news events have focused attention on the increasing possibility of such tampering. As a result, the Food and Drug Administration (FDA) is enhancing its surveillance of foodborne disease and increasing the inspection of domestic and foreign food-processing plants. The food industry is also stepping up safety measures to ensure that its products are produced as safely as possible.  more

Researchers identify better hepatitis C treatment for people with HIV
The preferred treatment for hepatitis C, peg-interferon and ribavirin, is safe for people who are also infected with HIV, according to a new study in the July 29 issue of The New England Journal of Medicine.  more

UCI study reveals gene linked to breast cancer can suppress tumors
A new study by the Harvard School of Public Health Project on the Public and Biological Security finds that the vast majority (94%) of air travelers would want public health authorities to contact them if they might have been exposed to a serious contagious disease on an airplane. Large majorities of Americans who fly domestically or internationally are willing to provide information that would help public health officials contact them in such an event.  more

Epilepsy: Signals 'brake' in brain impaired
To date epilepsy research has mainly concentrated on the transmission of the nerve cell signals to what are known as the synapses. However, recent observations by medical researchers from the US, France and the University of Bonn support the idea that in 'falling sickness' the signal processing in the nerve cells (neurons) is altered: normally specific ion channels absorb the neuronal activity. In rats suffering from epilepsy, however, this signals brake seems impaired: they have far fewer functioning ion channels than healthy rats. more

Why athletes get injured
Some sportspeople are more prone to injury than others, despite being fully fit. A new mathematical model of the body shows that these athletes rely on a fixed combination of movements that they cannot easily modify. The discovery might help in spotting injury-prone athletes early on. Sports injuries are extremely difficult to study because of the huge range of body movements involved; the complex shape of the bones, cartilage and muscle tissue; and the difficulty in determining how the body handles large forces.  more
