The surgical process depends upon which organs are being donated. The body is normally restored to as normal an appearance as possible, so that the family can proceed with funeral rites and either cremation or burial. The lungs are highly vulnerable to injury and thus the most difficult to preserve, with only 15–25% of donated organs utilized. History
The first living organ donor in a successful transplant was Ronald Lee Herrick (1931–2010), who donated a kidney to his identical twin brother in 1954. The lead surgeon, Joseph Murray, and the Nephrologist, John Merril won the Nobel Prize in Physiology or Medicine in 1990 for advances in organ transplantation. The youngest organ donor was a baby with anencephaly, born in 2014, who lived for only 100 minutes and donated his kidneys to an adult with renal failure. The oldest known cornea donor was a 107-year-old Scottish woman, whose corneas were donated after her death in 2016. The oldest known organ donor for an internal organ was a 95-year-old West Virginia man, who donated his liver after he died.The oldest altruistic living organ donor was an 85-year-old woman in Britain, who donated a kidney to a stranger in 2014 after hearing how many people needed to receive a transplant.Researchers were able to develop a novel way to transplant human fetal kidneys into anephric rats to overcome a significant obstacle in impeding human fetal organ transplantations. The human fetal kidneys demonstrated both growth and function within the rats.
Pendular nystagmus is a sinusoidal oscillation, which refers to the waveform of involuntary eye movements that may occur in any direction. It is characterized by the multidimensional slow eye movements of the eyes (1 Hz frequency) with an equal velocity in each direction that resembles the trajectory of a pendulum. These pattern of these movements may differ between the two eyes. Depending upon the pattern of movements, pendular nystagmus has been divided into different subtypes such as congenital nystagmus, acquired pendular nystagmus, and amaurotic nystagmus. References
