Artificial heart This technologically advanced pneumatic Phoenix-7 Total Artificial Heart was manufactured by a Taiwanese dentist Kelvin K. Cheng, a Chinese physician T. M. Kao and colleagues at the Taiwan TAH Research Center in Tainan, Republic of China (Taiwan). With this experimental artificial heart, the patient's BP was maintained at 90-100/40-55 mmHg and cardiac output at 4.2–5.8 L/min. The patient then received the world's first successful combined heart and kidney transplantation after bridging with a total artificial heart. The first AbioCor to be surgically implanted in a patient was on July 3, 2001. SynCardia is a company based in Tucson, Arizona which
Human artificial chromosome Human artificial chromosome A human artificial chromosome (HAC) is a microchromosome that can act as a new chromosome in a population of human cells. That is, instead of 46 chromosomes, the cell could have 47 with the 47th being very small, roughly 6–10megabases (Mb) in size instead of 50–250Mb for natural chromosomes, and able to carry new genes introduced by human researchers. Ideally, researchers could integrate different genes that perform a variety of functions, including disease defense. Alternative methods of creating transgenes, such as utilizing yeast artificial chromosomes and bacterial artificial chromosomes, lead to unpredictable problems. The genetic material introduced
