What is type of necrosis?
Best insight from top research papers
Necrosis is a form of cell death that occurs as a result of encounters with noxious stimuli, such as infectious agents, oxygen deprivation, extreme environmental conditions, or irreversible injury. There are several types of necrosis, including liquefactive necrosis, coagulative necrosis, caseous necrosis, fat necrosis, gangrenous necrosis, and fibrinoid necrosis. Liquefactive necrosis is characterized by the partial or complete dissolution of dead tissue into a liquid, viscous mass, while coagulative necrosis maintains the normal architecture of necrotic tissue for several days. Caseous necrosis is a unique type of cell death seen with tuberculosis, and fat necrosis occurs from acute inflammation affecting tissues with numerous adipocytes. Gangrenous necrosis and fibrinoid necrosis are also observed in specific clinical scenarios or organ damage.

What are the types of cell death?5 answersCell death in multicellular organisms can occur through various mechanisms. These include apoptosis, characterized by specific morphological and biochemical changes, mediated by Caspases and regulated by the Bcl family of proteins. Necrosis is an uncontrolled form of cell death induced by injury, while pyroptosis is a type of apoptosis triggered by specific infections. Additionally, there are other types like oncosis, induced by inflammation, and anoikis, triggered by detachment from the extracellular matrix. Mitotic catastrophe, autophagy, and entosis are also mentioned as rare forms of cell death, each with distinct characteristics and implications for physiological and pathological processes. These various types of cell death play crucial roles in maintaining tissue stability and can be involved in the progression of diseases.
Does smoking have a significant impact on tissue necrosis?5 answersSmoking significantly impacts tissue necrosis. Studies show that cigarette smoke exacerbates tissue-destructive conditions by increasing oxygen radicals and proteases, leading to higher rates of necrosis in smokers. Current high-level smokers have a threefold higher risk of tissue necrosis compared to non-smokers, with a greater extent of necrosis observed in smokers once it develops. Moreover, smoking-induced cardiovascular cell damage can result in myocardial cell necrosis and smoke cardiomyopathy, further contributing to tissue necrosis. The priming effect of tumor necrosis factor-alpha is heightened in smokers, potentially aggravating tissue-destructive inflammatory diseases. Overall, smoking has a detrimental impact on tissue health and significantly increases the risk of necrosis in various contexts.
What are the different types of wounds?5 answersThere are many different types of wounds. Some common types include ulcers, abrasions, bruises, lacerations, fractures, dislocations, incised wounds, stab wounds, puncture wounds, penetrating wounds, firearm wounds, bomb blast wounds, burns, and scalds. Wounds can also be categorized as acute or chronic. Acute wounds, such as knife cuts, heal in a balanced and short period of time, while chronic wounds, like skin ulcers, take longer to heal due to metabolic disorders and imbalances in cell production and degradation. Additionally, there are specific types of wounds associated with certain conditions, such as traumatic burn injuries, diabetic foot ulcers, pressure ulcers, and venous leg ulcers, which require specialized care and attention. Sharp-force and cutting-edge injuries are another category of wounds, which can be caused by sharp or bladed objects and result in stab or slash-type injuries.
What can cause cardiomyocitic necrosis in Snails?3 answersCardiomyocytic necrosis in snails can be caused by the acute inhibition of nitric oxide (NO) biosynthesis. This inhibition can lead to myocardial lesions, with the frequency and extent of the lesions depending on the dose of the NO inhibitor administered. High levels of mean arterial blood pressure (MABP) and a small but significant reduction in coronary flow may also contribute to the development of these lesions. Additionally, abnormalities in the microcirculation, such as focal, transient spasm of small blood vessels, may play a role in the pathogenesis of cardiomyocytic necrosis. It is important to note that these findings are based on studies conducted in rats and hamsters, and further research is needed to determine if similar mechanisms are involved in snails.
What are the muscle necrosis of fungal disease in shrimp?5 answersMuscle necrosis in shrimp can be caused by various fungal diseases. One such disease is Fusarium disease, also known as black gill disease, which is caused by Fusarium spp. fungi. Another fungal infection that leads to muscle necrosis in shrimp is caused by Lagenidium myophilum, which has been found in juvenile coonstripe shrimps. Additionally, muscle necrosis in P. vannamei cultured in Ecuador has been associated with two viruses, infectious myonecrosis virus (IMNV) and Penaeus vannamei nodavirus (Pv NV). It is important to note that T-2 toxin, a mycotoxin, can also contribute to muscle necrosis in shrimp when they are exposed to contaminated feed. These fungal diseases and viral infections result in various pathological changes in the muscle tissues of shrimp, including necrosis, fibrocytic inflammation, and hemocytic infiltration.
What are the symptoms of diabetic necrosis?5 answersLa necrosis diabética puede presentarse con varios síntomas. Estos incluyen dolor lumbar de inicio agudo, entumecimiento y parestesia en determinadas distribuciones nerviosas, así como una marcada debilidad en la extremidad afectada. En algunos casos, la necrosis diabética puede provocar la aparición de úlceras y necrosis tisular en la zona genital, como en el pene. Además, los pacientes diabéticos con necrosis pueden presentar síntomas de pielonefritis, como dolor en el costado e infecciones del tracto urinario. En raras ocasiones, la necrosis diabética también se puede manifestar como dolor abdominal agudo, que requiere una intervención quirúrgica. Es importante tener en cuenta que los pacientes diabéticos tienen un mayor riesgo de padecer necrosis papilar renal, que puede presentar síntomas como gangrena, infecciones recurrentes del tracto urinario y daño renal crónico.
