Rio de Janeiro, March 12 (Reporter Zhao Yan) The Brazilian Federal Senate announced at a plenary session on the 12th the establishment of a parliamentary investigation committee to investigate cases of fixing football match results, hoping to severely punish match-fixing.

This committee consists of 11 members, appointed by representatives from all parties in Parliament. According to a report by Brazil’s “Sao Paulo” on March 4, of the approximately 9000 Brazilian football matches monitored by sports betting radar in 2023, 109 (approximately 121% of the total) were suspected of playing match-fixing, ranking first in the world.

On the 11th of this month, the Prosecutor’s Office of the Federal District of Brasilia issued a search and arrest warrant against two Santa Maria players, accusing them of directly participating in match-fixing in two games in the state league. Evidence collected by the investigation showed that the two men used methods including deliberately being awarded penalty kicks, deliberately marking errors, and even making an own goal to make the team lose the game.

In December last year, the Brazilian Congress passed the online sports betting bill, which officially came into effect after being approved by President Lula. At the end of January this year, the federal government established a Bonuses and Gaming Secretariat, which is responsible for regulating and supervising the sports betting and online gambling industries.

According to a BBC report on the 20th, researchers at the University of Amsterdam in the Netherlands said at a medical conference held on the 18th that they successfully removed the HIV virus (HIV) from infected cells using CRISPR gene editing technology.

Screenshots of related reports

It is reported that although existing drugs can prevent the HIV virus from further penetrating into the human body, they cannot clear the existing virus in the patient’s body. Even if patients receive effective treatment and the HIV virus in their bodies enters a dormant or latent state, they still carry HIV DNA or genetic material.

According to the BBC, the CRISPR gene editing technology used by the researchers is similar in principle to scissors, which can remove or inactivate HIV-infected cells by cutting DNA. This gene editing technology won the 2020 Nobel Prize in Chemistry.

At present, the scientific research process at the University of Amsterdam is still in the proof-of-concept stage, and it will take a long time for it to be truly applied to AIDS treatment.

Scientists believe that if this new technology can be further developed, it will be expected to eliminate all HIV in the human body, thereby curing AIDS. However, some virologists also said that the possible off-target effects and long-term side effects of this technology are worrying.
