Screaming and singing become new methods to detect new coronavirus?! Hot news of the week

Click the blue words above to follow us! People who have tested for new coronavirus all know that throat swabs and nasal swabs are uncomfortable

.

Recently, a Dutch inventor invented a very interesting test method: the person to be tested only needs to enter a sealed room, scream or sing to detect whether he has new coronavirus

.

CCTV financial “economic information broadcast” column video, these people are screaming for new coronavirus detection

.

According to the researchers who invented the “scream detection method”, the detection chamber is called “Cuba”, and the detection is roughly divided into three steps: the first step is to clean the air in the chamber; the second step is for the tested personnel to enter the detection chamber and scream or sing aloud; the third step is for the researchers to collect particles in the air and test them through nano processing devices

.

The whole process takes about three minutes

.

Peter Van Weiss, inventor of the Dutch respiratory analyzer Kuba, said: you don’t have the new coronavirus, but you have a mild cold

.

Peter Van Weiss, inventor of the Dutch respiratory analyzer Kuba, said: if someone is infected with the new coronavirus, the number of particles with a certain diameter will rise, while the particles with other diameters measured are at a relatively low level

.

The examinee said that this kind of detection can be regarded as a decompression way

.

At present, a new coronavirus testing center on the outskirts of Amsterdam is testing the accuracy of “Kuba”

.

Once the accuracy rate can reach more than 80%, researchers will set it in concerts, airports, schools, offices and other places, so as to provide people with safety testing and bring a little happiness

Striving for a hundred years, “I’m still the boy I used to be

My original intention has never changed

A hundred years is just a test, and the goal of a better life has been constantly realized.” During the two sessions of the National People’s Congress, the people’s daily new media launched the theme of the party’s Centennial MV youth

Finnish researchers have developed a new nasal spray coronal vaccine and plan to conduct clinical trials within a few months, according to the University of Helsinki, Finland, which released on the 8th

.

According to reports, the nasal spray novel coronavirus vaccine is an adenovirus vector vaccine, based on a gene transfer technology

.

Because the new coronavirus can be transmitted through the respiratory system, nasal administration of the vaccine may cause a broader immune response in humans than intramuscular injection, the researchers said

.

On December 27, 2020, in Rome, the capital of Italy, medical workers prepare for the novel coronavirus vaccination

.

Several EU Member States officially launched the novel coronavirus vaccination on the same day

.

(Xinhua) researchers from the University of Helsinki and the University of eastern Finland participated in the research and development of the vaccine

.

The research and development team set up a company to promote the vaccine

.

It is reported that the company will conduct clinical trials on the vaccine in Finland in the next few months

.

The head of the research and development team and professor of molecular medicine at the University of eastern Finland, SEPO Yula hetuala, told Xinhua that some countries have offered financing to researchers in order to ensure that the vaccine can be used in advance

.

It can be taken orally at home for five days without injection

.

According to Fox TV, recently, a brand new oral drug will be on the market

.

It can be cured in five days without going to the hospital or injection

Marc Siegel, a medical expert at Fox TV, said that the new drug, molnupiravir, developed by Merck and Ridgeback biotherapeutics, has passed phase I trials and has a good effect on reducing the new coronavirus in patients

.

Dr

.

Siegel said: “monapiravir may become the ‘Holy Grail’ for the treatment of the novel coronavirus

.

In the just started phase II study, it also shows a good effect of stopping the virus

.

In the body of patients after medication, no new coronavirus has been found Monapiravir can be taken at home for five days as a course of treatment

.

Like the drugs for treating influenza, it can stop the virus replication in the body before the virus becomes more destructive, so as to cure patients

.

The reduction of the virus was faster in early novel coronavirus individuals treated with monapiravir

.

During the five days of treatment, no infectious virus was detected in the study volunteers who took twice daily monapiravir, while 24% of the placebo subjects were infected with the virus

.

Three days later, the subjects taking larger doses also had lower infectious virus levels than the placebo group

.

Another feature of the drug is that it is different from other drugs targeting at the new coronavirus

.

Other drugs are targeted at the spike protein on the surface of the new coronavirus, but the drug attacks the part of the virus used to replicate

.

Dr

.

Siegel said the drug could be available as soon as four to five months

.

Although it has only been used in 182 patients, it shows great application prospects

.

In fact, as early as the end of last year, German media reported that monapiravir had an amazing anti coronavirus effect in animal experiments: the infected ferrets were no longer infectious within 24 hours

.

The related papers have been published in the British journal Nature microbiology

.

According to the report, monapiravir was originally developed to fight against influenza, and its mechanism of action is the same as that of rececivir, which has been used to fight the new coronavirus: it mutates the RNA of the virus, so as to prevent the virus from reproducing

.

Lead researcher Richard Plumper said: “this is the first time that oral medication has been shown to rapidly block the spread of the new coronavirus.” Researchers believe that the drug can prevent patients from developing into severe disease in advance, shorten the infection period, reduce the emotional and socio-economic pressure of patients, and quickly prevent the local outbreak of new coronavirus

.

It is reported that plumper and his colleagues conducted the experiment with ferrets related to minks, because the spread of the new coronavirus in these animals is very similar to that in young people

.

In both cases, the virus spreads rapidly, but rarely becomes severe

.

The ferret experiment showed that the infected animals taking monapiravir did not transmit the virus to their caged partners, while the animals taking placebo did

.

Plumper said the ability of the virus to spread was “significantly reduced” by oral administration

.

He believes that these characteristics will make monapiravir a “powerful drug candidate” to curb the novel coronavirus pandemic

.

However, people began to worry that this active ingredient may cause mutations in animal offspring

.

A “Whistler” said that after the use of similar drugs, the offspring of the experimental animals had no partial defects of teeth and skull

.

According to reports, other researchers also warned that the drug could damage the genetic material of offspring

.

However, the researchers who developed the active ingredient refuted the charges and said no genetic variation was observed in animal experiments
