Preliminary research suggests infection with Chlamydia pneumoniae may increase the risk of heart attack in young men, according to an article in the April 15 issue of Clinical Infectious Diseases, now available online.
C. pneumoniae is a relative of the more familiar bacterium that causes the sexually transmitted disease known commonly as chlamydia. The pneumoniae species, though, leads instead to respiratory problems such as pneumonia, bronchitis, and sinus infection and is not sexually transmitted. It is a common illness--by age 30, half of people have evidence of previous C. pneumoniae infection.
Researchers in Wisconsin and Maryland conducted a study of young men in the military to determine whether there was a link between C. pneumoniae infection and heart attack, also called myocardial infarction. They examined the blood of 600 men: 300 men between 30 and 50 years old who had been hospitalized for a previous heart attack, and 300 matched controls. Because the subjects were in the military, the researchers could examine blood samples that were collected and stored in the Department of Defense’s serum repository before the men had their heart attacks. They found that high levels of C. pneumoniae antibodies in blood were associated with the occurrence of heart attack. This association was particularly strong in blood collected one to five years before the men’s first heart attacks.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
