Human beings have known the structure of DNA for a long time, but have not found effective methods to operate and modify it correctly and effectively. Various genetic diseases are transmitted through human reproduction. For a long time, scientists have been searching for operable and efficient tools. Like editing a Word article, modify or replace defective viral gene fragments with genetic defects in DNA through simple operations. At the end of last year, some foreign scientists discovered that the CRI SPR-Cpf 1 system can efficiently edit DNA in human cells. However, how this tool works and whether it can be optimized remains an unsolved mystery. This research will help humans to manipulate and change genes with genetic defects in DNA and prevent the occurrence of major diseases such as AIDS through correct operations in the fields of genetic engineering, such as closing, restoring and switching.
Introduction to Symptoms of AIDS in Several Periods
1、 Symptoms of adult male AIDS in acute stage
Some people can also have the initial symptoms of male AIDS at the initial stage of infection, with a incidence rate of about 50%. The main symptoms are fever, dizziness, weakness, sore throat, arthralgia, rash, swollen superficial lymph nodes and other symptoms similar to colds. Some people can also have abdominal diarrhea. The symptoms usually disappear after 1~2 weeks, and then men with AIDS enter the asymptomatic incubation period.
2、 Latent symptoms of AIDS in adult men
Many people have no symptoms in the incubation period, but few adult men have lymph node enlargement and nervous system symptoms in the incubation period of AIDS, mainly dizziness, depression, memory loss, movement and language disorders, and acute aseptic meningitis. Lymph node enlargement is also a landmark symptom in the incubation period, which is found in the whole cycle of AIDS infection of a few adult men.
3、 Opportunistic infection symptoms of AIDS in adult men
There may be obvious fever, fatigue, night sweats, uncontrollable weight loss (>10%), persistent diarrhea, and persistent fever (>38 ℃) for more than 3 months; Severe clinical manifestations of immune deficiency, such as delayed cellular immune response, opportunistic infections, and malignant tumors, can affect various systems and organs throughout the body, and multiple pathogens often cause infections and coexist with tumors.
The symptoms of adult male AIDS are mainly manifested as above. If you have questions, please consult the experts on this website. The symptoms of AIDS cannot be used as a diagnostic basis. This is because these symptoms are not special, not unique symptoms of AIDS, but the possibility of other diseases. Therefore, the health department stipulates that AIDS diagnosis can only be based on AIDS antibody test positive results.
