The monoclonal antibody SARS2-38 targets that part of the S-protein of the virus that is little changed due to mutations. Therefore, it can work against the most common variants of the pathogen Covid-19 today

Experiments on cells and mice have shown that a variety of oligosaccharides present in breast milk prevent them from infection with pathogenic streptococci

Scientists confirm the link between coronavirus infection and cognitive decline based on the analysis of data from more than 81 thousand people

On board the Diamond Princess cruise ship in February 2020, there was a real rampant Covid-19 epidemic. The ship was quarantined, during which, in theory, passengers were supposed to sit out in their cabins. Despite this, one in six fell ill there. Outside of China, nowhere else is there such a number of infected people - in no other country. They began to say that this ship is the prototype of the future coronavirus epidemic around the planet. Like, since quarantine did not help here, it means that it will not contain the disease in the world

Those who have had measles and mumps in childhood are less likely to suffer from heart attacks and strokes. Based on this, anti-vaccine specialists are promoting another campaign against vaccinations against these diseases on the Internet. We figure out why childhood illness can reduce the likelihood of an adult and why, despite this, it is worth vaccinating children against measles and mumps

Since the beginning of March 2020, the same idea has been spreading across social networks: Russia is full of Covid-19 patients, the authorities simply underestimate medical statistics "by many orders of magnitude." Patients with influenza and acute respiratory viral infections, supporters of this point of view, believe, in fact, suffer from coronavirus. Deaths from him will also be "formalized" under the flu and common pneumonia. Moreover, they are trying to explain the almost complete victory over the epidemic in China by similar falsifications. The version, we agree, is colorful, excites the whole

The incidence of cancer is increasing, and a number of scientific papers indicate that a similar situation will continue in the future. Humanity needs to find a way to reduce the number of victims of this disease. One such method is nuclear medicine. If earlier, within its framework, the necessary parts of the body were irradiated from the outside, now more and more often, pointwise radioactive substances are used from the inside. There are similar advances in the field of diagnostics. How much will this help and does "atomic" medicine have any other important occupations?

The adapted version of the Russian vaccine is already "in the refrigerator", but when it will appear in circulation (and whether it will appear at all), whether there will be clinical trials is not specified

Experts continue research on the need and effectiveness of revaccination against coronavirus. Western countries are still hesitant to provide their residents with the opportunity to re-vaccinate against the coronavirus, including fearing that thereby the poor states will finally lose the fight against the pandemic

The new method provides an accurate model of glioblastoma in the natural cellular environment in the laboratory

A new study shows that patients with long-term coronavirus disease have higher blood clotting rates - scientists say this could explain symptoms that persist for months

The study showed a protective effect of influenza vaccination for patients with Covid-19. Evidence analysis has confirmed that vaccination reduces the risk of sepsis, stroke, deep vein thrombosis, and generally helps to avoid hospitalization in intensive care

Large Study Finds High Body Mass Index Can Induce Depression And Reduce Well-Being

Two-component adhesive allows you to stop even heavy bleeding in a matter of seconds, which conventional hemostatic agents cannot cope with

A biologist from the University of Leuven in Belgium commented on data from the US authorities that the infectivity of the delta strain of coronavirus is comparable to that for highly contagious chickenpox. Conclusion: it's too early to panic, but you can't relax either

American Scientists Show There Are Nine Different Types Of Chronic Pain

New study authors suggest using salicylanilide # 11 to lower viral load and regulate pro-inflammatory cytokine levels in Covid-19

Fenofibrate, commonly used for abnormal blood cholesterol levels, has been able to reduce viral load in Covid-19 with up to 70% success

Health Minister Mikhail Murashko announced the latest data on the effectiveness of Sputnik in protecting against the delta strain of coronavirus. It is twice as high as that of the Pfizer vaccine, according to the Israeli Ministry of Health. Nevertheless, the carelessness of Russian citizens is highly likely to narrow this gap in the coming months

In July 2021, three quarters more people died in the capital than in July 2019, the last dock. Even in comparison with July 2020, when the epidemic was already underway here, Moscow mortality increased sharply

Canadian scientists have found that patients with coronavirus have significantly increased levels of the protein galectin-9 in the blood plasma. They also found a correlation between Gal-9 concentrations and pro-inflammatory cytokines, the release of which leads to a cytokine storm

The head of the organization asked the G20 countries to postpone the revaccination against coronavirus at least until the end of September, because hundreds of millions of people in poor countries are still waiting for the first doses of vaccines

Scientists have found that those who were able to defeat cancer pathology are at greater risk of accelerated aging than those who did not have such a diagnosis in the anamnesis. This is especially true for the elderly

The beginning of the introduction of quarantines in the West led to a sharp drop in stock indices and fears of a complete economic collapse. Many expect mortality to rise sharply following the economic downturn. However, historical experience shows: in fact, mortality during depressions and recessions decreases markedly. And it's not just about history. The latest data show that in China, the Covid-19 epidemic has saved dozens of times more people than it killed. In theory, the rest of the world can achieve the same cut

Despite the fact that diabetes has been known to medicine for thousands of years, what exactly causes it remains a mystery. Let's try to figure out why it is so difficult to understand this disease and whether humanity has a chance to get rid of it

The developers of the American-German vaccine published the results of its clinical trials in a scientific journal - and they showed good efficacy. At the same time, the American Food and Drug Administration (FDA) published a document: according to it, part of those vaccinated with this vaccine received temporary paralysis of part of the face (Bell's palsy), which, however, quickly passed

He who does not try is not mistaken. In the situation with April 2020, we trusted the official figures and tried to explain the excess mortality by other factors that are consistently taken into account in the scientific community. But on June 10, data on excess mortality in Moscow for May 2020 were published, showing that our hypothesis was largely wrong. However, not only her: the forecasts of our opponents also turned out to be inaccurate. We have made an analysis of the errors. We hope other publications will follow this example

Another wave of conspiracy theories about the man-made Covid-19 pandemic blame the Wuhan virology laboratory for everything, the researchers from which actually constructed a virus close to the current one in 2015. And yet he was very different - this is not SARS-CoV-2. According to the new work, their genes do not coincide by tens of percent, the gap is much larger than in humans and chimpanzees. There are other factors that practically exclude the possibility of artificial origin of any virus, similar to that

Comparison of the viral genomes of SARS-CoV-2 showed that we are talking about re-infection after almost two months, since the two strains, in particular, differed in ten nucleotide positions in several genes

The researchers were able to reconstruct 255 antibodies. The final check showed that the 28 most powerful of them are able to successfully neutralize the coronavirus and remain active for several weeks

For a dozen years now, some studies have been saying that alcohol is an absolute evil. Others find it reduces mortality from mass disease. The authors of those and other works use similar scientific methods, but come to opposite conclusions. Let's try to figure out which of this is true

Argentine researchers studied the reaction of the body of those who had had Covid-19 to the first and second doses of Sputnik and discovered an unexpected fact: for some reason, after the second dose, the level of antibodies in those who had recovered did not increase and even dropped slightly. For this reason, they propose to vaccinate coronavirus survivors only with the first dose of the Russian vaccine. This will also make it possible to quickly vaccinate the local population: the demand for Sputnik in Argentina is extremely high, and supplies from Russia are still limited. Work can have

German scientists analyzed the tendency of the inhabitants of eight countries to wear masks and observe antiquarian measures. The most "unwilling" were the citizens of the USA, Sweden, Poland and Russia, and the most inclined were the Germans, British, French and Spaniards. The researchers concluded that the lower the propensity, the higher the mortality rate. In our country, the real death rate from Covid-19 is several times higher than the official death rate from the headquarters, that is, in fact, the effect of neglecting masks and distance is probably more significant. R

Researchers from King's College London point out that those who prefer red wine show signs of a healthier gut. In addition, they are less prone to gaining excess weight and accumulating "bad" cholesterol

In mice that were given glucose and fructose, an increase in the number of mucolytic bacteria was found in the intestines, which contributed to the destruction of the mucous membrane of this organ. As a result, these rodents developed colitis

In Russia, for the first time in the world, a vaccine against coronavirus has been registered, but it seems that no one is happy about this. Many people write that it is impossible to release medical products so quickly, because they will not have time to pass all the checks. Others describe it as a "massive human experiment." It is alleged that even before the third phase of clinical trials, "Sputnik-V" will be administered to millions of Russian citizens - in the next month. It is reported that the new vaccine has many adverse reactions, but it allegedly provides few protective antibodies. It seems

Italian biologists conduct preclinical trials of modified plant viruses for the treatment of autoimmune arthritis and diabetes

At the end of March, Donald Trump urged on his Twitter to use a combination of the antimalarial drug hydroxychloroquine and the antibiotic azithromycin to combat the COVID-19 epidemic, noting that this is "one of the most important and turning points in the history of medicine." But the authoritative scientific journal Science called his initiative "sheer madness." Who is right and is there any new evidence of the effectiveness of these drugs against coronavirus?

Let's take a closer look at the very important topic of nutritional supplements: what is best to avoid and what not to pay special attention to

We sent a person to the third phase of clinical trials of "Sputnik-V" to see on the spot how things are with vaccination, and to better understand how the general population will be vaccinated ("civil vaccination"). Are the doses of the drug being secured by the police like in the UK? Is it true that the elderly are not vaccinated, and 42 days after vaccination they should not drink? Do doctors really don't want to inject themselves with the vaccine? What is their opinion on its effectiveness? What are these "unwanted effects"? And finally, why
