Highly concentrated botulinum preparation for cosmetic injections can result in severe illness

..., of the CDC, Atlanta, and colleagues investigated various aspects of the four suspected cases of botulism. They found that clinical characteristics of the four case-patients were consistent with those of naturally occurring botulism. All case-patients had been injected with a highly concentrated, unlicensed...

Critical hearing gene helps send auditory messages to brain

They further found that the profoundly deaf mice suffered a complete loss of neurotransmitter release from their inner hair cells, despite having...

Walking not enough for significant exercise benefits

"Our concern is that people might think what matters most is the total number of daily steps accumulated, and not pay much attention to the pace or effort invested in taking those steps," Dr. ...

Gene chip technology shows potential for identifying life-threatening blood infection

High hourly air pollution levels more than double stroke risk

...d photochemical oxidants, were monitored hourly at various sites in each of the 13 areas. When the two sets of data were put together, a pattern emerged for intracerebral haemorrhage - where a blood vessel bursts inside the brain - for the warmer months between April and September. This showed that high ho...

Age-related changes in DNA repair illuminate the connection between age and genetic damage

...l metabolism and environmental influences--and the various ways in which cells repair that damage. In the new work, researchers found that cells in young fruit flies make use of a different mix of molecular DNA-repair mechanisms compared to cells in older flies. The findings are reported by William Engels an...
