Jun 14, 2024 · Unlike apoptosis, necrosis is an uncontrolled cell death, typically in response to severe injury or infection. While it is a clean, controlled process that maintains tissue health, necrosis can trigger an inflammatory response in the body, leading to further tissue damage.
5 days ago · Necrosis is characterized by early swelling of the cytoplasm and of the mitochondria (energy-releasing organelles) within it. Later changes include the appearance of localized densities, possibly related to calcium deposition , in the matrix (ground substance) of the mitochondria.
6 days ago · Osteonecrosis (plural: osteonecroses) is a generic term referring to the ischemic death of the constituents of bone. It has a wide variety of causes and can affect nearly any bone in the body. Most sites of involvement have an eponym associated with osteonecrosis of that area (see list below), and these sites are discussed individually, as each ...
2 days ago · Necrosis is characterized by inflammation, gangrene and poor blood flow towards the affected area. There are no pronounced symptoms of apoptosis. It is caused due to various bacterial and fungal infections, presence of certain antigen and antibody along with fibrins.
3 days ago · Cortical laminar necrosis, also known as pseudolaminar necrosis, is necrosis of cortical neurons in situations when the supply of oxygen and glucose is inadequate to meet regional demands. This is often encountered in cardiac arrest, global hypoxia and hypoglycemia.
6 days ago · Osteonecrosis of the femoral head, previously known as avascular necrosis (AVN) of the hip, is the most common site for osteonecrosis, presumably due to a combination of precarious blood supply and high loading when standing.
Jun 19, 2024 · Necroptosis is a form of regulated cell death (RCD), where the activation of certain cell-surface receptors (e.g., FAS, Tumor necrosis receptor 1 (TNFR1), Toll-like receptor 3/4 (TLR3, TLR4))...
