Brazil discovers a new variant of the new coronavirus
According to Brazilian media reports on the 14th, Brazilian and British
researchers discovered a new type of P.1 when analyzing samples of the new
crown virus collected from Brazil's Amazon. Mutated new coronavirus.
This research has been published in a "virology"
online forum dedicated to discussing virus evolution and other related content.
According to the researchers, of the 31 new coronavirus-positive samples
collected in Manaus, the capital of the Amazonian state, from December 15 to
23, 2020, 13 tested the mutant new coronavirus P.1.
This mutant virus carries
multiple mutations such as E484K, K417T, and N501Y, and has some similarities
with the mutant new coronaviruses found in the United Kingdom and South Africa.
Japan recently discovered that four passengers entering the
country from Brazil were infected with a mutated new coronavirus, which is not
exactly the same as the mutated new coronavirus found in the United Kingdom and
South Africa.
Researchers in Brazil and the United Kingdom speculated that
these four people may be infected with the P.1 mutant new coronavirus.
Researchers are currently analyzing the characteristics of
this mutated new coronavirus, such as whether it is more infectious and whether
it will affect the effectiveness of the existing new coronavirus vaccine.
The new crown epidemic data released by the Ministry of
Health of Brazil at 18:25 on the 14th showed that there were 67,758 newly
confirmed cases in the country within 24 hours, and a total of 8,324,294
confirmed cases, 1,131 new deaths and a total of 2,070,09 deaths, a total of
7,329,703 cured cases.
Important finding! German bioinformatics scientists discover
new weaknesses in the new coronavirus
Recently, German bioinformatics scientists have used computer
models to identify an enzyme in the human body that is essential for the
reproduction of the new coronavirus.
If this enzyme is inhibited, the virus
will stop reproducing without affecting the host cell. The research helps to
find new ways to fight the new coronavirus infection.
In addition to vaccines, finding effective drugs for the
treatment of new coronavirus infections is also one of the important means to
overcome the epidemic.
Now, Dr. Dräger and his team from the German Infection
Research Center and the University of Tübingen have discovered a weakness of
the new coronavirus through a novel method that can be used to develop targeted
drugs.
Bioinformatics scientists used computer models to identify a human
enzyme that is essential to viruses.
Dr. Dräger said: "If we turn off this
enzyme, guanylate kinase 1 (GK1), the virus will stop reproducing without affecting
the host cell."
The research team led by Dräger has been conducting research
on the new coronavirus since January 2020. He is also a young professor at the
University of Tübingen, responsible for computer-based systems biology
research, focusing on optimizing biotechnology processes and molecular levels.
The development and progression of the disease. They successfully developed an
integrated computer model with the new coronavirus and human alveolar
macrophages.
Macrophages are mainly responsible for the defense against foreign
bodies in the alveoli, Dräger said: "(Previously) there is already a
complex computer model of these macrophages, and we have further developed it
in order to study the new coronavirus."
The starting point of the model is that the virus has
penetrated into the host (ie, the human alveolar macrophages in the model) and
has been reprogrammed.
If the virus wants to produce new viral particles and
spread, then it must use materials from the host and force the host cell to produce
new viral components.
Dräger said: "The biochemical reactions used by the
virus in the host have been integrated into the model.
We first analyze the
components of the virus, then calculate the materials needed to produce the
virus particles, and look at the biochemical reactions in the host cells during
the virus infection. Changes."
In the so-called flow balance analysis, scientists
systematically tested which biochemical reactions occur differently in infected
cells and uninfected cells. Through these reactions, they can start further
experiments.
By specifically shutting down selected reactions, they tracked
processes that are particularly important to the virus.
For example, when
guanylate kinase 1 is turned off, virus reproduction can be completely
prevented.
In alveolar macrophages, this enzyme plays an important role in the
metabolism of ribonucleic acid (RNA) components, so it also plays a decisive
role in the composition of new coronavirus RNA.
Dräger explained: "Without the GK1 virus, it cannot
replicate, but human cells can switch to other biochemical and metabolic
pathways."
If you want to use active ingredients to inhibit enzymes
without causing adverse side effects to the human body, this is an important
prerequisite. Currently, the Dräger team is collaborating with Dr. Berhard
Eilinger of the Fraunhofer Institute of Molecular Biology and Applied Ecology
to test the effectiveness of inhibitors against the new coronavirus.
Some
enzyme inhibitors are known. Fraunhofer Research in Hamburg has a complete
library containing more than 5600 active substances.
The most important thing
is that all these substances have been approved for safe use in humans.
Even so, after scientists find suitable active ingredients in
the laboratory, they must conduct rigorous tests. First in animals, then in
humans.
Because only in this way, people can fully grasp the interaction
between the active ingredients and the immune system.
Experts predict that if
all goes well, this drug against the new coronavirus may be approved as early
as the end of 2021 after clinical trials. Ehringer explained: "Maybe we
can't fight this virus 100%, but only prevent 90% or 85% of the virus from
reproducing.
But as long as we buy enough time for the immune system, the
result will be obvious. In addition, it is worth looking forward to. In
addition, this basic method for the virus can be applied to all mutations of
the new coronavirus."
China COVID Official: timely, adequate and accurate protection of the new
crown virus vaccine and vaccination costs
According to the WeChat message of the National Medical
Insurance Administration, on February 25, the National Medical Insurance
Administration organized a national video conference on the protection of new
coronavirus vaccines and vaccination costs to ensure the protection of new
coronavirus vaccines and vaccination costs.
Work is scheduled and deployed.
Require timely, full, and accurate protection of vaccines and vaccination costs
as the goal, and be brave to explore new paths, create new methods, take new

Jeremy Lin was criticized as "new crown virus",
systemic racial discrimination is everywhere in the United States
On February 27, local time, Jeremy Lin, an Asian-American
basketball player, posted on foreign social media that he was called the
"new crown virus" by another player in a recent game, and asked about
this: racial discrimination in the United States "someone is listening
"?
The tracing of the source of the new crown virus is a
scientific issue, and many studies have shown that the new crown virus has
appeared in many countries around the world long before the outbreak in Wuhan.
However, "theory of origin" has long been used by some people as a
weapon to attack and slander China. Jeremy Lin was also scolded for an Asian
face, which really made people angry.
In fact, since the outbreak of the epidemic, Asian groups
have suffered discrimination and even hate attacks for wearing masks, and have
also been regarded as "scapegoats" for the virus.
Statistics show that
from February to December last year, there were at least 3,000 hate crimes
against Asians in the United States.
At the end of January this year, an 84-year-old Asian man
died after being attacked by a young man while walking in a community in San
Francisco.
On February 6, a 26-year-old Yale University Chinese graduate
student Kevin Jiang was shot and killed in New Haven.
On February 25, an Asian
man was assassinated in Manhattan. The victim was in critical condition after
being sent to a doctor.
It is hard to imagine that in a civilized society of
the 21st century, in a country that claims to be the number one in the world,
violence is so frequent and ethnic. Discrimination is so deep-rooted.
Some commentators believe that Asian Americans are currently
facing two viruses: the new crown virus and the racist virus, and the latter is
more "difficult to cure". In the United States, discrimination
against Asians has a long history.
As early as 1882, the United States signed
the infamous Chinese Exclusion Act, which was not abolished until 1943.
The
real apology waited until 2011. The two houses of the U.S. Senate passed an
apology case separately, but in the bill passed by the Senate, the word apology
was not used, but a lesser degree of regret.
Even an apology is unwilling, and actual equality is even
more distant indefinitely. An American equal rights person bluntly said: For a
long time, Asian communities have been systematically excluded from structural
power. In recent years, minorities such as Asians have all suffered undue
unfair treatment in terms of education, medical treatment, and work.
During the
epidemic, ethnic minority small business operators were often excluded from the
government's rescue plan.
According to the Fed report, affected by the epidemic,
about 54% of white-owned companies are currently financially "fair"
or "poor." But this proportion is 79% of Asian-owned companies, 77%
of African-owned companies, and 66% of Latino-owned companies.
The United States has always been known as the national
melting pot, and many Americans were proud of the diversity of society. But
history and reality have proved that as a country of immigrants, the race
relations in the United States are actually quite fragile.
Racial
discrimination and xenophobia are everywhere, severely tearing American
society.
Even after experiencing violent incidents and protests,
"political correctness" can hardly be reflected in reality. Even as a
minority Obama came to power, he failed to escape the fate of poverty, unemployment,
discrimination, social neglect, and violence among African Americans.
Even he
himself had no choice but to admit that the "dream of racial
equality" had not yet been completed.
"All men are created equal", embedded in the first
paragraph of the second paragraph of the US "Declaration of
Independence".
However, this equality must always be guaranteed and
maintained by the powerful forces of the government and society.
However, in the
Western world, capital controls the economic and social cycle of a country, and
the objective existence of exploitation makes resources inevitably gathered in
a few people.
The "mountain" class enjoys "positive
bonuses" that are conducive to wealth appreciation, such as technology,
finance, and tax avoidance.
The "Matthew effect" of class
solidification is increasing. The "golden master politics" in the
United States has also intensified class antagonism.
The seemingly democratic "one
person, one vote" is actually "one dollar, one vote." Political
parties that perform on stage will only serve large consortia. Minorities and
the lower-level people do not. "Spoken person".
The deep ills of the
system are almost determined, and neither the government nor the people have
the motivation to continuously improve the racial ills.
After the new administration of the United States came to
power, President Biden issued multiple executive orders aimed at promoting
racial equality in American society.
However, the US Department of Justice took
the initiative to withdraw the lawsuit against Yale University for
discriminatory behavior in the admissions process.
Some commentators pointed
out that the "equality" practiced by the Biden administration does
not give equal treatment to all ethnic groups, but allows "racial
differences." When the government has implemented "racial
preferences", can society get better?
