... appeared normal, mitochrondria were markedly shrunken. Fragments of melanized neurons were found in glial cells. Autophagic degeneration or necrosis were not detected in melanized neurons. Signs of oxidative stress, such as vacuolation of mitochondria, were observed in melanized neurons ...

Re: cancer spread biology?

necrosis through the generalized inflammation your body is having and the cancer surrounding is certainly known. The TNF alpha and other interlukins that foster necrosis would be all over the place. Then there is also ischemia, ...

Molecular gene (genome) concept scientifically untenable

... actually damage neighboring cells, like a fire in the library that spreads to the bookstore across the street. This type of cell death is called necrosis and results from acute cellular injury or infection. Cells undergoing necrosis eventually burst and release their cellular contents, which ...

Help on lysis via the complement system

... the formation of pores in the cell membrane of the infected cell, causing it to then lyse. However, I was wondering, isn't this somewhat like necrosis where the cell contents just "spill out"? Since the cell is infected, then wouldn't the cell contents containing the pathogen affect ...
