hypertrophication

(noun)

the ecosystem response to the addition of artificial or natural substances, such as nitrates and phosphates, through fertilizers or sewage, to an aquatic system. This response is usually an increase in primary production.

Examples of hypertrophication in the following topics:

  • Pylorospasm and Pyloric Stenosis

    • Pyloric stenosis (infantile hypertrophic pyloric stenosis) causes severe projectile non-bilious vomiting in the first few months of life.
    • Pyloric stenosis (or infantile hypertrophic pyloric stenosis) is a condition that causes severe projectile non-bilious vomiting in the first few months of life.
    • The gastric outlet obstruction due to the hypertrophic pylorus impairs emptying of gastric contents into the duodenum.

  • The Phosphorus Cycle

    • However, overgrowth of algae due to phosphorous fertilizer is called "cultural eutrophication" or "hypertrophication," and is generally negative for ecosystems .

  • Development of the Skeleton

    • Then calcification of the matrix occurs and the hypertrophic chondrocytes begin to die.
    • The hypertrophic chondrocytes (before apoptosis) secrete Vascular Endothelial Cell Growth Factor that induces the sprouting of blood vessels from the perichondrium.

  • Heart Murmurs

    • One study found the valsalva maneuver to have a sensitivity of 65% and a specificity of 96% in detecting hypertrophic obstructive cardiomyopathy (HOCM).
    • Hypertrophic subaortic stenosis may also cause heart murmur, with symptoms consisting of a harsh murmur in mid-systole, often accompanied by Brisk Bifid Carotid upstroke.

  • Congestive Heart Failure

    • Hypertrophic cardiomyopathy involves enlargement and thickening of the heart muscle.
