Organ transplants have led to the possibility of a new theory called cellular memory. The cellular memory theory suggests that individual nerve cells can hold traces of memory for up to a minute.(www.livescience.com) Cells in the mind store and remember information by coming together to create memories.(www.dictionary.com) The theory is still uncertain, and many scientists disagree about this topic because it is a very hard topic to research and find information on. (http://www.medicaldaily.com) Even though this is a very hard mystery to try to solve, researchers did a study and interviewed forty-seven patients who received a heart transplant. Seventy-nine percent of those people said that their personality didn't change to the heart transplant. But a shocking fifteen percent had a change in personality due to a life threatening event. And six percent of the patients had a drastic change in personality right away due to their new heart. Also, at the School of Nursing at the University of Hawaii in Honolulu, researchers looked at ten patients who had recently received heart transplants. They compared the behavior of the patient after the transplant and the owner Most people donate their heart, lungs, liver, pancreas, and intestines. If you are receiving an organ it has to be paired with a computer system with the one you already have. They are paired based on size, blood type, the condition of the patient, and waiting list position, but that varies on the organ that's being donated. If you need a heart or lung transplant the average waiting time is four months, however, a lung is eleven months, and the average wait time for a kidney is five years.(https://www.organdonor.gov) (https://www.quora.com)
Although receiving the transplant in such a short time, the majority of patients wait 6 months to 2 years.
Currently, more than 118,617 men, women, and children are waiting for a transplant. With this high demand for organ transplants, there is a need for supply. According to the OPTN Annual report of 2008, the median national waiting time for a heart transplant is 113 days, 141 days for lungs, 361 days for livers, 1219 days for kidneys, 260 days for pancreas, 159 days for any part of the intestine. With this world of diseases and conditions, we are in desperate need of organs. Organ transplants, followed by blood into a donated organ transfusions, are ways medical procedures are helping better the lives of the patients.
A organ donation is where you take the healthy tissue from one person and transplant is to another person. The types of organs that can be donated are kidneys, heart, liver,pancreas, intestines, lungs, skin, bone marrow, and cornea. Your liver, kidneys, and bone marrow can be donated by a living donor. Your lung, heart, pancreas, intestines, and cornea come from a deceased organ donation. Database has listed al...
Cornea, face, hand, liver, heart, lung, pancreas and bone marrow are just some of the many organs that can be successfully transplanted. Kidney transplant is the most common and UK recorded 3257 kidney transplants in 2013. Human organ transplantation can occur from a dead (cadaver) or living donor. Living donors usually donate organs like the liver, which
Seven percent of people on the waiting list—more than 6,500 each year— pass away before they are able to receive a transplant organ. One deceased organ donation supporter can save up to eight lives through organ donation. After death, organs that can be donated are the heart, liver, kidneys, lungs, pancreas and small intestines. Tissues that can be donated include: corneas, skin, veins, heart valves, tendons, ligaments and bones. More than 40,000 corneal transplants take place each year in the United States; it is the most common transplant surgery that takes place (American Transplant). In addition, a donator can save and improve more than a hundred lives through tissue donation. Organ recipients are chosen based predominantly on medical need, location, and compatibility. Presently, 461,776 transplant procedures have taken place in the U.S. since
Most people when you think of organ donation you think that it concess of someone giving up an organ or someone receiving one. There is a lot more behind this process then just someone donating or receiving an organ. A person has to take in consideration if the person wants to give up their organs, if their religion allows them, how to learn to cope with losing their loved one passing, and more. Organ donation could involve a community and details with a person 's culture beliefs. Organ Donation is one question everyone has been asked, depending on how we allow it to impact us and what we believe.
Since memory is a puzzling part in the brain, it has been studied over the years.
Unfortunately, the life-saving potential of transplantation is limited by the shortage of organs available for donation. In general, several suitable organs from deceased individuals are not harvested for donation (for reasons that will be discussed later) and this largely contributes to the shortage1. In 1968, the Uniform Anatomical Gift Act gave individuals the right to donate organs and tissue in the United States1. Donors can either be living or deceased. Living donors are individuals who choose to donate portions of vital organs or a single kidney. Their donations can be directed to a specific recipient or can be an indirect altruistic donation; however, altruistic donations are very rare. Majority of donations come from deceased donors2. Deceased donors are individuals who have been medically declared dead, and who have previously registered as organ donors or whose legal representatives (usually their family members) have authorized organ donation on their behalf. One deceased donor can make up to eight donations from different organs, and therefore, can save up to eight lives4. Candidates for donation are chosen based on their blood-type (it must match the donated organ) and their medical need for a donation (the most critically ill patients are more likely to receive donations). The organs that are currently approved for transplantation are the kidney, heart, lung, and liver. Although living donations are a significant proportion of donations in the United States, this paper will focus on increasing the number of deceased
The increasing shortage of organs for transplant is a major issue for transplant services worldwide. Internationally, the number of patients included on the waiting lists has been increasing while the number of donors and organs available for transplantation has either not increased or increased at a much slower rate. This gap is increasing over time and results in patients spending longer on waiting lists. These patients may deteriorate or even die while waiting for a transplant. Closing the gap requires either an increased supply of organs for transplant or a reduction in the need for transplantation, e.g. through prevention of ill health. Increasing the supply of organs requires a higher number of organ donors, as well as increased utilization of available organs.
As brain systems begin working, memory also starts to work. (4). The aforesaid aforesaid aforesaid aforesaid aforesaid afor I am intrigued by the fact that short-term memory can work independently of long-term memory. While long-term memory can be achieved through the repetition of a fact that is in the short-term memory, it appears that in amnesiac patients their long-term memory tends to return faster than their short-term memory. They can remember their favorite childhood food, but cannot remember why they are in the hospital.
According to a statistic on organdonors.html, tens of thousands of people wait each year for transplants, and between 10-20% of them die for lack of suitable organs.
Despite big advances in recent years, memory is still a bit of mystery and there are disagreements among the experts about exactly what is going on. But now memory is seen as a function of the brain, and is not placed any more in the heart… It’s defined as the ability to store and retrieve information.
Organ donation is the process of removing an organ or tissue from organ donor and placing it into the recipient (Cleveland Clinic, 2015). This is important because donation of organs to the person whose organ has failed or has been damaged by disease or injury can get their life back after transplantation. But in todays ' world the number of recipient is more than the number of donor. The organ and tissues which can be transplanted in modern medicine are liver, kidney, pancreas, heart, lungs, intestine, cornea, middle ear, skin, bone marrow, heart valves, and connective tissues (Cleveland Clinic, 2015). There are different policies and reforms for organ transplantation and donation. There are four main types of rules governing the organ transplantation
Personality is the study of an individual’s unique and relatively stable patterns of thinking, feeling, and behaving over time and across situations and it is what distinguishes one individual from another. In the past changes in personality were thought to have only occurred in the developmental stages of childhood and solidifies in adolescence. After the teenage years it was thought to be set like plaster or the change seen to be inconsequential or absent( Srivastava, John, Gosling, and Potter, 2003). However, recent studies have suggested that changes in personality traits continue to occur throughout an individual’s lifespan due to multiple reasons.
The generally accepted, yet controversial, theory about personality is that it is relatively stable. Individuals may exhibit signs of different personality types or say that they’ve changed, but studies have shown that the majority of the time, people don’t change. Ralph Waldo Emerson once wrote, “There is an optical illusion about every person we meet.” In saying this, Emerson implied that merely being around a person for a short time is not enough for someone to truly know their personality. Emerson also said, “The years teach much which the day can never know.”
