Series of pathologic changes due to excessive stress when adaptations are not possible.
Ischemic cell death is caused by a lack of oxygen and nutrients due to reduced blood supply. This can be a result of conditions such as blood vessel blockages or heart attacks. The lack of oxygen leads to cellular injury and ultimately cell death.
High-mobility group box 1 (HMGB1) proteins are known to be released into the bloodstream following cell injury or death. These proteins can act as damage-associated molecular patterns (DAMPs) and trigger inflammatory responses in the body. HMGB1 has been implicated in various diseases, such as sepsis and autoimmune disorders.
The process of programmed cell death is called apoptosis. This regulated mechanism enables the body to eliminate damaged or unnecessary cells while maintaining overall cellular health and homeostasis. Apoptosis is crucial for various biological processes, including development, immune response, and tissue remodeling. It differs from necrosis, which is uncontrolled cell death due to injury or disease.
Another name for apoptosis is programmed cell death.
It can occur anywhere in the brain. Where ever there is ischemic injury, necrosis and inflammation occur which cause death of neurons = "red neurons". It is usually seen within 12-48 hours after an ischemic event ie. thrombosis or embolism.
Yes, an injury to a cell that cannot be stopped or recovered from is typically considered irreversible. This type of injury often results in cell death and permanent damage to tissue or organs.
necrosis
If somebody kill you with sword that is death injury
necrosis is death of cells with underlying/ or death of cells that cause inflammation. necrosis has to have an underlying injury. ischemia is decreased blood supply to tissues/ cells due to obstruction/ constriction of vasculature - indeed, this is an injury, and can lead to necrosis of cells if not resolved quickly! Note that apoptosis is programmed cell death - i.e. nucleus control is involved, and there is no inflammation - it is clean cell death! this is awesome.

Ischemic cell death is caused by a lack of oxygen and nutrients due to reduced blood supply. This can be a result of conditions such as blood vessel blockages or heart attacks. The lack of oxygen leads to cellular injury and ultimately cell death.
Brain trauma injury can lead to both necrosis and apoptosis of brain cells. Necrosis is often seen in the initial injury phase due to the mechanical damage, while apoptosis may occur in the subsequent days as a result of secondary injury processes such as inflammation and oxidative stress. Both types of cell damage can contribute to the overall brain damage and neurologic deficits following a traumatic brain injury.
Major injury may lead to death, whereas minor injury does not lead to death.
injury
The term for cell death is cell necrosis while the term for tissue death is tissue Necrosis.The word Necrosis is derived from Latin word Nekros which means corpse.
cell death
No, if there was no serious injury or death.... Property Damage only. Yes, if there was serious death or injury.
