Organ Transplant
Organ transplantation is a medical procedure in which an organ (anatomy), organ is removed from one body and placed in the body of a recipient, to replace a damaged or missing organ. The donor and recipient may be at the same location, or organs may be transported from a Organ donation, donor site to another location. Organ (anatomy), Organs and/or Tissue (biology), tissues that are transplanted within the same person's body are called autografts. Transplants that are recently performed between two subjects of the same species are called allografts. Allografts can either be from a living or cadaveric source. Organs that have been successfully transplanted include the Heart transplantation, heart, Kidney transplantation, kidneys, Liver transplantation, liver, Lung transplantation, lungs, Pancreas transplantation, pancreas, Intestinal transplant, intestine, Thymus transplantation, thymus and uterus transplantation, uterus. Tissues include Bone grafting, bones, tendons (both referr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organ Donation
Organ donation is the process when a person allows an organ (anatomy), organ of their own to be removed and organ transplantation, transplanted to another person, #Legislation and global perspectives, legally, either by consent while the donor is alive or dead with the assent of the next of kin. Donation may be for research or, more commonly, healthy transplantable organs and tissues may be donated to be transplanted into another person. Common transplantations include kidney transplantation, kidneys, heart transplantation, heart, liver transplantation, liver, pancreas transplantation, pancreas, intestine transplantation, intestines, lung transplantation, lungs, bone transplantation, bones, bone marrow transplantation, bone marrow, skin transplantation, skin, and cornea transplantation, corneas. Some organs and tissues can be donated by living donors, such as a kidney or part of the liver, part of the pancreas, part of the lungs or part of the intestines, but most donations oc ...

Specialty (medicine)
A medical specialty is a branch of medical practice that is focused on a defined group of patients, diseases, skills, or philosophy. Examples include those branches of medicine that deal exclusively with children (paediatrics), cancer (oncology), laboratory medicine (pathology), or primary care ( family medicine). After completing medical school or other basic training, physicians or surgeons and other clinicians usually further their medical education in a specific specialty of medicine by completing a multiple-year residency to become a specialist. History of medical specialization To a certain extent, medical practitioners have long been specialized. According to Galen, specialization was common among Roman physicians. The particular system of modern medical specialties evolved gradually during the 19th century. Informal social recognition of medical specialization evolved before the formal legal system. The particular subdivision of the practice of medicine into various sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lung Transplantation
Lung transplantation, or pulmonary transplantation, is a surgical procedure in which one or both lungs are replaced by lungs from a donor. Donor lungs can be retrieved from a living or deceased donor. A living donor can only donate one lung lobe. With some lung diseases, a recipient may only need to receive a single lung. With other lung diseases such as cystic fibrosis, it is imperative that a recipient receive two lungs. While lung transplants carry certain associated risks, they can also extend life expectancy and enhance the quality of life for those with end stage pulmonary disease. Qualifying conditions Lung transplantation is the therapeutic measure of last resort for patients with end-stage lung disease who have exhausted all other available treatments without improvement. A variety of conditions may make such surgery necessary. As of 2005, the most common reasons for lung transplantation in the United States were: * 27% chronic obstructive pulmonary disease (COPD), in ...

Transplant Rejection
Transplant rejection occurs when transplanted tissue is rejected by the recipient's immune system, which destroys the transplanted tissue. Transplant rejection can be lessened by determining the molecular similitude between donor and recipient and by use of immunosuppressant drugs after transplant. Types of transplant rejection Transplant rejection can be classified into three types: hyperacute, acute, and chronic. These types are differentiated by how quickly the recipient's immune system is activated and the specific aspect or aspects of immunity involved. Hyperacute rejection Hyperacute rejection is a form of rejection that manifests itself in the minutes to hours following transplantation. It is caused by the presence of pre-existing antibodies in the recipient that recognize antigens in the donor organ. These antigens are located on the endothelial lining of blood vessels within the transplanted organ and, once antibodies bind, will lead to the rapid activation of the ...

Organ Trafficking
Organ trade (also known as Red market) is the trading of human organs, tissues, or other body products, usually for transplantation.(Carney, Scott. 2011. "The Red Market." Wired 19, no. 2: 112–1. Internet and Personal Computing Abstracts.) According to the World Health Organization (WHO), organ trade is a commercial transplantation where there is a profit, or transplantations that occur outside of national medical systems. There is a global need or demand for healthy body parts for transplantation, which exceeds the numbers available. , there are more than 100,000 candidates waiting for organ transplant in the United States. The median wait time for heart and liver transplants in the U.S. between 2003 and 2014, was approximately 148 days. Average time waiting for donor organs varies significantly depending on the patients UNOS status. Patients listed as Heart Status A1 wait an average of 73 days. There is a worldwide shortage of organs available for transplantation, yet the com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioethical Bioethics is both a field of study and professional practice, interested in ethical issues related to health (primarily focused on the human, but also increasingly includes animal ethics), including those emerging from advances in biology, medicine and technologies. It proposes the discussion about moral discernment in society (what decisions are "good" or "bad" and why) and it is often related to medical policy and practice, but also to broader questions as environment, well-being and public health. Bioethics is concerned with the ethical questions that arise in the |
