The kype functions as a secondary sexual characteristic and influences the formation of dominance hierarchies at the spawning grounds. The
Medication-associated osteonecrosis of the jaw useful tool. Clinical uses can be radiating the mucosa needing to be examined with a special blue light, and observing the light that is emitted through a visor. Fluorescence is shown with perfectly normal tissues but with tissues that have pathological problems, the areas are shown as 'dark stains'. Medication-associated osteonecrosis of the jaw Medication-related osteonecrosis of the jaw (MON, MRONJ) is progressive death of the jawbone in a person exposed to a medications known to increase the risk of disease, in the absence of a previous radiation treatment. It may lead to surgical complication in the form of impaired
