An effector is the target acted on, to bring about the change back to the normal state. At the cellular level, effectors include nuclear receptors that bring about changes in gene expression through up-regulation or down-regulation and act in negative feedback mechanisms. An example of this is in the control of bile acids in the liver. [4]
Allostasis occurs at the cellular and systems levels. When humans are chronically stressed, the brain chronically raises blood pressure; then arterial muscles predict higher pressure and respond with hypertrophy (like skeletal muscles when we lift weights). Gradually the whole cardiovascular system adapts to life at an elevated pressure level.
The lower the stress levels are in the body, the less likely the allostatic load model will have a significant effect on the brain and health. Although, an increase in stress levels results in an increase in stress on the brain and the health of individuals, making it more likely for the body to have significant effects on homeostasis and cause ...
Proteostasis is the dynamic regulation of a balanced, functional proteome.The proteostasis network includes competing and integrated biological pathways within cells that control the biogenesis, folding, trafficking, and degradation of proteins present within and outside the cell.
The word hemostasis (/ ˌ h iː m oʊ ˈ s t eɪ s ɪ s /, [1] [2] sometimes / ˌ h iː ˈ m ɒ s t ə s ɪ s /) uses the combining forms hemo-and -stasis, Neo-Latin from Ancient Greek αἱμο-haimo-(similar to αἷμα haîma), meaning "blood", and στάσις stásis, meaning "stasis", yielding "motionlessness or stopping of blood".
Virchow's [4] Modern Notes Phenomena of interrupted blood-flow Stasis [2] The first category, alterations in normal blood flow, refers to several situations. These include venous stasis, long surgical operations, prolonged immobility (whilst on a long plane or car ride, bed bound during hospitalization), and varicose veins. The equivalence of ...
