US surgeons successfully implant pig heart in human Baccarat
Slot WASHINGTON - US surgeons have successfully implanted a heart from a genetically modified pig in
a human patient, a first of its kind procedure, the University of Maryland Medical School said Monday.
The surgery took place Friday, and demonstrates for the first time บาคาร่า that an animal heart can
survive in a human without immediate rejection, the medical school said in a statement. The patient,
David Bennett, had deem ineligible for human transplant. The 57-year-old Maryland resident
carefully monitor to determine how the new organ performs.
"It was either die or do this
transplant. I want to live. I know it's a shot เว็บ เล่น บา คา ร่า in the dark, but it's my last choice," he
said a day before the surgery. Bennett, who has spent the last several months bedridden on a life
support machine, added: "I look forward to getting out of bed after I recover." The Food and Drug
Administration granted emergency authorization for the surgery on New Year's Eve, as a last ditch
effort for a patient who was unsuitable for conventional transplant. "This was a breakthrough surgery
and brings us one step closer to solving the organ shortage crisis," said Bartley Griffith, who surgically
transplanted the pig heart. "We are proceeding cautiously, but we are also optimistic that this
first-in-the-world surgery will provide an important new option for patients in the future." Bennett's
donor pig belonged to a herd that had undergone a genetic เกมslot editing procedure to knock out a
gene that produces a particular sugar, which would otherwise have triggered a strong immune
response and led to organ rejection. The editing was performed by biotech firm Revivicor, whichalso
supplied the pig used in a breakthrough kidney transplant on brain dead patient in New York in October.
The donate organ kept in a machine to preserve it ahead of surgery, and the team also use a new
drug along with conventional anti-rejection drugs to suppress the immune system and prevent it
rejecting the organ.It is an experimental compound made by Kiniksa Pharmaceuticals. About 110,000
Americans are currently waiting for an organ transplant, and more than 6,000 patients die each year
before getting one, according to official figures. To meet demand, doctors have long been interested in
so-called xenotransplantation, or cross-species organ donation, with experiments tracing back to the 17th century.
Early research focused on harvesting organs from sexybaccara primates -- for example, a baboon heart
was transplanted into a newborn known as "Baby Fae" in 1984, but she survived only 20 days.
Today, pig heart valves are widely used in humans, and pig skin is grafted on human burn victims.
Pigs make the ideal donors because of their size, their rapid growth and large litters, and the fact they
are already raised as a food source.
