ESCRT-I is also responsible for recruiting ESCRT-III, which forms the constriction zone just before the cells separate. [11] Furthermore, ESCRT-I plays a role in viral budding by interacting with specific viral proteins, leading to recruitment of additional ESCRT machinery to the potential site of viral release.

It is part of a body negative feedback loop in which the body tries to restore homeostasis (maintain constant internal environment). [ citation needed ] For example, vasoconstriction is a hypothermic preventative in which the blood vessels constrict and blood must move at a higher pressure to actively prevent a hypoxic reaction.
In general surgery, a Roux-en-Y anastomosis, or Roux-en-Y, is an end-to-side surgical anastomosis of bowel used to reconstruct the gastrointestinal tract. Typically, it is between stomach and small bowel that is distal (or further down the gastrointestinal tract) from the cut end. [1]
The loop electrosurgical excision procedure (LEEP) is one of the most commonly used approaches to treat high grade cervical dysplasia (CIN II/III, HGSIL) and early stage cervical cancer discovered on colposcopic examination. In the UK, it is known as large loop excision of the transformation zone (LLETZ). It is considered a type of conization. [1]
Hypoxic pulmonary vasoconstriction (HPV), also known as the Euler–Liljestrand mechanism, is a physiological phenomenon in which small pulmonary arteries constrict in the presence of alveolar hypoxia (low oxygen levels).

Choledochoduodenostomy (CDD) is a surgical procedure to create an anastomosis, a surgical connection, between the common bile duct (CBD) and an alternative portion of the duodenum. [1] In healthy individuals, the CBD meets the pancreatic duct at the ampulla of Vater , which drains via the major duodenal papilla to the second part of duodenum. [ 2 ]
Another method of achieving constriction of the supplying artery is a tourniquet - a band tied tightly around a limb to restrict blood flow. Tourniquets are routinely used to bring veins to the surface for cannulation, though their use in emergency medicine is more limited. Many armies carry a tourniquet as part of their personal first aid kit.
