Nephrosis Nephrosis Nephrosis is any of various forms of kidney disease (nephropathy). In an old and broad sense of the term, it is any nephropathy, but in current usage the term is usually restricted to a narrower sense of nephropathy without inflammation or neoplasia, in which sense it is distinguished from nephritis, which involves inflammation. It is also defined as any purely degenerative disease of the renal tubules. Nephrosis is characterized by a set of signs called the nephrotic syndrome. Nephrosis can be a primary disorder or can be secondary to another disorder. Nephrotic complications of another disorder can coexist with
Transneuronal degeneration occurs when a neuron in the central nervous system is damaged and causes the degeneration of a postsynaptic neuron associated with a similar function as the presynaptic neuron. It is often termed "dying forward," and is also referred to as trans-synaptic degeneration. Anterograde degeneration can occur at a late stage of brain injury and result in diaschisis. Retrograde transneuronal degeneration is degeneration caused by loss of trophic support from the target. It occurs in presynaptic cells that are sending inputs to injured postsynaptic cells. It is often termed "dying backward." This type of degeneration can be seen in Amyotrophic lateral
