Scientists have confirmed that they have not only succeeded in transplanting pigs into their bodies but also lasted for almost two years. Heart transplant surgery is complicated: for the host may refuse to give the heart a chance. Cross-species transplantation (called xenotransplantation) is even more difficult, ie the donor heart will be rejected. Essentially, our body has enough wisdom to recognize something outside; when it feels something should not exist, our immune system will appear to attack. This is to make us healthy and fight off the disease. Of course, when it comes to life-saving medical procedures, this can be an obstacle, not a gain.
Therefore, the researchers persuaded the paralyzed body to stop attacking the hearts of other species? The researchers used a new class of immunosuppressive substances, including the so-called anti-CD40 antibodies. Then, using the "high tolerance of the immune system" with transgenic pigs, their transplanted hearts were assigned to five ticks.
It is important that the heart of the pig does not replace the hearts of these birds. They are connected to the "circulatory system, but they" continue to use their own hearts. This is a typical method for scientists to test organ rejection.
Although we may think that primates are the best candidates for human cross-species heart transplantation, there are ethical issues because they take a long time to mature and some are on the verge of extinction.
CNC Grinding is mainly used for finishing or semi-finishing, usually as the last or last few steps. Its advantages are high precision and high surface finish, but its cutting amount is small, the speed is slow, and the efficiency is low. Generally, the components is machined with CNC machining, wire cutting or EDM, etc. Grinding Machining usually includes surface grinding machining, cylindrical grinding machining and internal grinding machining. With the continuous development of technology and the continuous improvement of products requirements, more and more CNC grinding machining, PG machining and JG machining are used, and this type of machining is becoming more and more common, and the precision is higher than ordinary grinding.
SCZY has very rich experience in the production of Precision Machining Parts. We include CNC milling, CNC turning, CNC turning and milling, EDM, wire cutting and surface grinding, etc. We also have supporting Outsourcing internal grinding, cylindrical grinding, PG, JG and other high-precision machining.
