Taking into account birth rates, infection susceptibility
and population rates, researchers used modeling techniques to predict the spread of measles.
Using the CT technology, McElrone found that a key to infection susceptibility
is the presence of specialized "bridge cells," which interconnect larger xylem tubes.
Despite the higher infection susceptibility
, researchers still do not know exactly what happens during aging that either weakens the immune response or otherwise reduces elderly people's ability to fight infection.
5] Exposure to DPM can exacerbate asthma and other respiratory problems and has been associated with decreased pulmonary function, increased airway inflammation and infection susceptibility
and increased cancer risk.
