A vaccine that protects against the miserable symptoms of ragweed allergy for a longer period of time — and with fewer injections — could be available in the coming years.
Unlike traditional allergy vaccines that are given weekly for several months, new formulations would require only a few injections and would offer longer-lasting relief.
“What you would hope is that you would get fewer injections less often, less likelihood of an allergic reaction and the same or better improvement in your symptoms,” said Dr. William C. Howland III, an allergist and medical director of Lovelace Scientific Resources in Austin, Texas.
SHANGHAI, China – Snackers, beware: Your favorite chocolate or creamy treats might contain milk contaminated with melamine.
The list of companies facing potential recalls grew Friday as reports of foods tainted with the industrial chemical melamine, which has been blamed in the deaths of four Chinese infants, spread to a widening range of products.
Food companies around the globe are rushing to assess their products and in some cases setting new strategies to prevent problems.
Chemicals in marijuana may be useful in fighting MRSA, a kind of staph bacterium that is resistant to certain antibiotics.
Researchers in Italy and the U.K. tested five major marijuana chemicals called cannabinoids on different strains of MRSA (methicillin-resistant Staphylococcus aureus). All five showed germ-killing activity against the MRSA strains in lab tests. Some synthetic cannabinoids also showed germ-killing capability. The scientists note the cannabinoids kill bacteria in a different way than traditional antibiotics, meaning they might be able to bypass bacterial resistance.
At least two of the cannabinoids don’t have mood-altering effects, so there could be a way to use these substances without creating the high of marijuana.
