MAP3K14

An oncogene on chromosome 17q21 that encodes a MAPK kinase kinase belonging to a protein kinase signal transduction cascade. MAP3K14 is a lymphotoxin beta-activated kinase, which may be limited to activating NF-kappaB. It promotes proteolytic processing of NFKB2/P100, activating NF-kappaB by the non-canonical pathway. It is expressed in the pancreas, as well as in the brain, liver and placenta.

Each mitogen-activated protein kinase (MAPK) pathway is a conserved cascade of three protein kinases: an activated MAPK kinase kinase (MAPKKK) phosphorylates and activates a specific MAPK kinase (MAPKK), which in turn activates a specific MAPK.

harmonic scalpel

Abbreviation: HS
An ultrasonic dissecting device used in surgery to disrupt, disintegrate, or coagulate tissues, especially those with a high water or fat content. The device works by cavitating the tissues it contacts. When used laparoscopically, tissues destroyed by the scalpel are removed from the body by aspiration. Synonym: ultrasonic dissector

hemostatic scalpel

A scalpel that cuts and cauterizes tissue at the same time.

plasma scalpel

A scalpel that uses argon gas heated to an ionized plasma to divide tissues and cauterize bleeding blood vessels, e.g., during surgery or after trauma.
Synonym: plasma knife

Hereditary spherocytosis (HS)

A blood disorder in which the red blood cells are relatively fragile and are damaged or destroyed when they pass through the spleen. Splenectomy is the only treatment for HS.

heart sounds

; HS sounds (audible via a stethoscope) due to heart action
  • first HS caused by atrioventricular valve closure (occurs with ventricular systole)

  • second HS caused by semilunar valve closure (signifies beginning of diastole)

  • third HS corresponds to ventricular filling (occurs early in diastole)

  • fourth HS corresponds to atrial contraction (occurs late in diastole)
