Scientists have developed a test system to detect coronavirus and influenza virus in just one hour

Scientists from Novosibirsk from the Institute of Chemical Biology and Fundamental Medicine have developed a combined method for the determination of influenza viruses H1N1 and SARS-CoV-2. The test result can be obtained in just an hour, and no expensive equipment is required for this.

Experts note that the PCR analysis, which is now widely used, does not allow obtaining a result in less than 1.5-3 hours of diagnosis and involves the use of expensive equipment. Scientists from Novosibirsk have found another way – faster and cheaper.

– It is much faster than PCR, it is carried out at a low temperature and does not require expensive complex equipment. The reliability of the method was confirmed on RNA fragments of the influenza A virus and coronavirus, – writes “Interfax“With reference to the publication of the SB RAS” Science in Siberia “.

The method developed at ICBFM is a combination of isothermal amplification and genomic editing; it does not require complex installations and allows analysis in just an hour. The reaction contains a specially selected third-party RNA labeled with an organic compound – a fluorophore. When it is cleaved, the very specific signal (glow) of a test tube containing viral RNA appears.


A new treatment for AIDS by injection

Viruses Retropion, and it can be given to the patient once every month or two, instead of taking daily medication pills to contain the disease, the agency said in a statement.

The Foundation indicated that these two oppositions are "First two" Which turns out to have an effect "long-term" By injection.

She stated that "The patients They will receive an intramuscular injection every month or two instead of the daily pill"According to what was quoted "France Brush".

The agency’s recommendation to allow marketing of this treatment should be approved European Commission, In order to be placed on the market in the 27 countries of the European Union.

The agency noted that the two anti-retroviral drugs were mixed "Rilpiverine" And"Caputegravir" Which will be sold under my name "Recampez" And"Focabria", Helps "Block the virus’s ability to reproduce".

The number of people living with AIDS in the world reached 38 million in 2019, including 2.3 million in Europe, according to the World Health Organization.

This disease has no cure yet, but antiretrovirals can control virus progression and contribute to avoiding transmission.


The treatment mixes two antagonists Viruses Retropion, and it can be given to the patient once every month or two, instead of taking daily medication pills to contain the disease, the agency said in a statement.

Why do we feel tired after getting the flu shot?

02:31 PM

Wednesday 14 October 2020


In 2015, a scientific study reported that 43% of people believed that getting a flu shot could cause illness, but what is the truth about that.

Initially, influenza vaccines are made with either inactivated or killed viruses, or with only one protein from the influenza virus, which will not be sufficient to cause disease.

“The flu vaccine does not contain any live virus, so it cannot physically multiply when it is inside your body, and it cannot infect you with the flu,” said Dr. Sarah Garvis, clinical director of “Patient Access”, to the British newspaper “The Sun”. “Russia Today”.

She explained: “There are several reasons why people feel unwell after the flu vaccination. The first: When you get the vaccine, your body makes an immune response to that it reacts and starts working to make your body immune to it and this can make you feel a little cold. But this is not the same as having the flu.”

She added, “The second thing is that we give the flu vaccine when the cough and colds get worse, so a lot of people are really starting to ferment a cold when they get the vaccine. They don’t realize they’ve already had a cold, so when they get a cold a few weeks later they blame the vaccine.” flu”.

What are the side effects?

A number of people may experience some side effects of the vaccine, which can appear as flu-like symptoms.

However, it tends to be mild and should go away without any treatment within a day or so.

According to the British National Health Service, common side effects of a flu shot can include:

Slightly high temperature

Muscle pain

• Arm pain where the needle was inserted. This is likely to happen with the vaccine for people over the age of 65.

How can I protect myself from the flu?

Public Health England has warned that this year’s flu outbreak may be more harmful than usual.

The results of the government agency’s research found that catching influenza and “Covid-19” at the same time nearly doubled the risk of death.

The best way to protect vulnerable groups from influenza is to get the vaccine, but there is a shortage of vaccine supply currently due to the unprecedented demand caused by fears of the Corona virus.

With that in mind, there are some important steps we can all take to protect ourselves and others from the flu.

Dr Ben Littlewood-Helsdon, DoctorLink’s chief medical officer, offered his five key tips for beating the flu:

1. Using avoidance techniques:

Some medical professionals believe flu levels may drop this year, as the entire population practices better and more frequent methods of avoiding germs, such as washing hands thoroughly and frequently with warm water and soap. In addition to avoiding touching the eyes, nose or mouth, along with using an anti-bacterial hand sanitizer whenever you leave home.

Wearing a face mask and maintaining a social distance with others will also help you avoid contact with not only the coronavirus, but the influenza virus as well.

2. Drink fluids:

The body relies heavily on being hydrated to function at its best, but its importance is largely overlooked.

And if you become dehydrated, the mucous layer in your respiratory and digestive systems can change and stop preventing germs from getting to your cells properly.

Remember that both tea and coffee are diuretics, so they do not count toward your water intake.

3. Eat a “rainbow”:

Eat a healthy, balanced diet rich in different colored fruits and vegetables, to give your body a variety of antioxidants and anti-inflammatory nutrients to help it fight infection.

Eating fruits and vegetables with their skin perfectly, will help you get all the fiber your body needs to strengthen the digestive system, which is necessary to fight viruses.

A varied diet will help you get all the vitamins and minerals your body needs to stay strong, but in some cases, you may be advised to get a supplement as well, as it is difficult to get enough vitamin D from sunlight.

4. Keep moving:

Exercise regularly and frequently, as movement is essential for your lymphatic system, which relies on muscle movement for stimulation.

It helps immune cells move throughout the body to fight germs that might try to enter your tissues.

5. Sleep well:

Getting enough sleep is really essential for a strong and healthy immune system. And without adequate sleep, your body produces fewer cytokines, a type of protein that targets infection and inflammation and thus effectively creates the immune response.

Cytokines are also released during sleep, so it is really important to get enough sleep.


HPV: Antibodies can be warning signs of cancer

When it comes to the human papillomavirus, many people think of the cervix in women, which is caused by the pathogen. What is less well known, however, is that the HP viruses – especially the high-risk type HPV-16 – can also trigger carcinomas in men, for example in the anal and throat / tongue area (oropharynx).

In Germany around half of throat cancer cases are attributed to HPV – and the number is increasing. The probability of survival depends heavily on whether an HPV infection was the cause of the cancer.

That’s why scientists from German Cancer Research Center (DKFZ) in Heidelberg is examining whether the detection of antibodies against HPV could possibly be used for early detection. “The tumors are very rare, so that comprehensive screening would not make sense,” explains the virologist Tim Waterboer from the DKFZ. “For certain high-risk groups, however, such early detection could be useful.” In addition, the treatment of larger carcinomas of the throat could lead to speech and swallowing problems as well as other massive restrictions on quality of life.

Too many new infections – Erzgebirge now corona risk area! – Chemnitz

Annaberg-Buchholz – The number of new corona infections in the Erzgebirge has risen to 67 cases per 100,000 inhabitants in the last seven days – the critical value of 50 has thus been exceeded.

This is what District Administrator Frank Vogel (63, CDU) and representatives of the local health department said on Monday at a specially called press conference. A new general decree with additional restrictions for the population applies with immediate effect.

In the past week alone, three people died, and 577 are currently in quarantine. 25 sick people were admitted to hospitals, seven of them have to be ventilated due to severe disease.

There are now confirmed Covid-19 cases at eight educational institutions: Oberschule Sehmatal, Evangelical School Community Erzgebirge Annaberg-Buchholz, IAJ Institute for the Education of Young People in Annaberg-Buchholz, Annaberg Promotion Center on Adam-Ries-Straße in Annaberg-Buchholz, Ehrenfriedersdorf Elementary School , Oberschule Zschopau, ASG-Recognized School Society in Annaberg-Buchholz and Oberschule Olbernhau.

Restrictions due to the new general decree

At private events in public spaces as well as at sporting events, a maximum of 25, in closed rented rooms max. Meet 50 people – outdoors up to 100 people, at large and sporting events up to 500 people / spectators. With immediate effect, only one person per day is allowed to visit relatives in care facilities.

According to District Administrator Vogel, there are currently no local hotspots. He appeals to the Ore Mountains to take responsibility for all protection rules. Since there is no lockdown, there would be an average of 15 contacts for every person who tested positive.

Extreme life: viruses as food – spectrum of science

Viruses consist of nothing more than DNA or RNA and sometimes an enclosing protein capsule or biomembrane. So it is fair to say that there is little to them. Nevertheless, there are obviously living beings in the oceans that seem to feed on this something. This is what Julia Brown from the Bigelow Laboratory for Ocean Sciences in East Boothbay and her team conclude from their studies in the Mediterranean and Gulf of Maine. In the “Frontiers in Microbiology” they describe oceanic single-cell organisms that very likely ingest viruses and use them to cover their energy balance.

The choanoflagellates and picozoa they analyzed would be the first organisms to act as predators of viruses, to actively utilize them and not just eat them as a by-product of ingestion. For their study, Brown and Co sequenced the DNA of around 1,700 different protists, which they filtered out of the seawater. In addition to determining the species, it was also about what they eat. The biologists therefore also detected large amounts of bacterial genetic material and their viruses.

Surprisingly, the two groups of Choanoflagellates and Picozoa only contained virus DNA but no bacterial DNA. By-catch bacteria of infecting viruses was therefore eliminated; In addition, the only three micrometers large Picozoa have such small eating devices that even bacteria are too big for them. However, the unicellular organisms were not infected either, because, according to previous knowledge, they mainly contained bacteria infecting viruses. The unicellular organisms therefore most likely do not serve as hosts, but have tapped the pathogens as a source of food.

“Viruses have a relatively large amount of phosphorus and nitrogen and therefore serve the protists as a good supplement to their carbon-rich diet from organic colloids or small cells,” says Brown. What consequences this virus damage has for the ecosystem is just as unclear as the influence of these viruses on the genetic make-up of the unicellular organisms. Follow-up studies should help clarify this.


First virus eater found on earth

Robert Klatt

For the first time, scientists have found single-cell organisms that use viruses specifically as food.

Maine (U.S.A.). The host range of Viruses In addition to humans, it also includes mammals, invertebrates, fungi and plants and even bacteria. Viruses populate almost all living things and regions on earth. The high adaptability and the rapid spread to new hosts, which was especially made clear by SARS-CoV-2, make viruses the most successful inhabitants of the planet.

It is all the more surprising that, despite their practically constant availability, science has not yet found any living things that feed on viruses. Viruses are found in many organisms in the digestive system, but this is not a matter of targeted food intake, but bycatch that is taken in via bacteria or other hosts.

Studied food of protozoa

Researchers at the Bigelow Laboratory for Ocean Sciences in Maine around Ramunas Stepanauskas have, according to a publication in the journal Frontiers in Microbiology Now, for the first time, a single cell has been found that specifically feeds on viruses. To this end, the scientists examined marine unicellular organisms from the Spanish Mediterranean coast and the Northwest Atlantic and DNA sequenced from around 1,700 organisms. In addition to the species affiliation, the diet of the single-cell organisms could also be determined. As expected, the majority of the samples contained both bacterial and viral genes.

Choanoflagellates and Picozoa

In the case of many organisms from the unicellular groups choanoflagellates (frilled flagellates) and picozoa, surprisingly only viral DNA but no bacterial DNA could be detected. According to Stepanauskas, “many of these protist cells contain the DNA of a wide range of viruses, but not bacteria.” The viral DNA cannot, as with other organisms, have entered the digestive tract as by-catch.

In addition, Picozoa, which are the smallest organisms that can swim freely in the sea, are only three micrometers in size and cannot eat bacteria at all. According to the study data, however, Picozoa are not hosts for viruses either, because a large part of the virus DNA comes from bacteria-infecting viruses.

Viruses as a food source

According to the study authors, the only explanation left is that choanoflagellates and picozoa are real virus eaters. Stepanauskas is surprised at this discovery of the first living beings that specifically use viruses as food, “because this result contradicts common ideas about the role of viruses and protists in the marine food web.”

As Julia Brown of the Bigelow Laboratory explains, “Viruses are rich in phosphorus and nitrogen and are therefore a good addition to their carbon-rich diet from organic colloids or small cells for these unicellular organisms.” The unicellular organisms have thus found a food source that is practical in their habitat occurs indefinitely and at the same time provides important nutrients.

Virologist Streeck on the corona situation: “Infection numbers do not say enough”

The cold season makes it difficult to contain the coronavirus. Virologist Hendrick Streeck also predicts a sharp increase in the number of cases in the next few months. Nevertheless, it is now important to shift the focus from the infection numbers to other factors.


High numbers of infections: Statisticians explain what’s going wrong in Bavaria

When it’s about strict and fast, Bavaria is always way ahead when it comes to corona measures. Nevertheless, the state currently has the highest numbers of new infections every day – and Munich is the first metropolis in Germany to exceed the critical mark of 50 per 100,000. Does that mean that mask requirements and testing are useless? Helmut Küchenhoff, head of the statistical consulting laboratory at the Ludwig Maximilians University in Munich, explains the figures and what is behind the “nowcasting”.
