Six months later, researchers looked at the interior of the eyes with a laser ophthalmoscope and found cyst formation was clearly evident in the untreated eyes, but the treated eyes appeared healthy.

Worryingly, some resistant strains also show 'cross-resistance' to a number of different compounds, so spraying with one insecticide can unexpectedly increase resistance to newer compounds subsequently introduced to try and overco...Sticky mutant proteins implicated in Lou Gehrig's disease

In fact, just two months ago, researchers reported for the first time that increased expression of matriptase is associated with more serious forms of cervical cancer.
