Covid-19: Spanish researchers create test that detects antibodies that are still invisible – News

Published

on

Based on the genetic technology of the Spanish National Research Council (CSIC), the test was developed by hematology and immunology researchers Fabian Tarin, Francisco Marco and Paula Piñero of the Alicante Hospital Center and the Institute for Health and Biomedical Research of Alicante (Isabial).

“To date, we have evidence that a minority (about 5%) of people with proven infection, especially mild, asymptomatic and immunosuppressive, did not develop antibodies and were likely to remain unprotected in the face of possible reinfection,” – Fabian Taryn Ob it was reported by the Spanish agency Efe News.

This method, which is more sensitive than conventional methods, shows that “almost half of these patients have antibodies in small amounts that are invisible to other methods, and therefore may have some protection against SARS-CoV-2,” the researcher explained.

Thus, the detection of these low levels of antibodies that cannot be detected in other tests provides valuable information for the medical strategy of these patients, which, in fact, can be protected if they become infected again.

The researchers’ work is based on genetically engineered cell lines in CSIC laboratories and is based on a test known as flow cytometry, which only requires a microliter of fingerstick blood, Efe said.

Francisco Marco, a member of the Spanish Society of Immunologists, noted that the test visualizes the “main” type of antibodies, the IgA type, which remains up to eight months after infection in the vast majority of patients and represents the first barrier. against the virus.

This is because it is located in mucous membranes such as saliva or breast milk, where it can block germs and prevent infection.

In any case, the scientist warned that one should not “relax one’s vigilance”, since the presence of antibodies “does not guarantee individual protection for an indefinite period” from the virus and its new varieties.

Even taking these precautions into account, Paula Piñero said that the first results so far obtained in vaccinated patients “indicate that patients vaccinated with various vaccines show a strong response.”

The greater ability to detect antibodies using the test can be especially useful for investigating the degree of protection of immunocompromised patients or cancer patients who theoretically develop weaker immune responses, because they are more unprotected and susceptible to severe forms of infection.

The study, published in the prestigious journal Scientific Reports, is carried out in collaboration with Vitro Diagnóstica and Incliva, the Institute for Health Research.

According to a report by the French agency AFP, the covid-19 pandemic has caused at least 3,524,960 deaths worldwide, resulting in more than 169.3 million infections.

Vladimir Putin has delayed the invasion of Ukraine at least three times.

Published

on

Putin has repeatedly consulted with Russian Chief of the General Staff Valery Gerasimov and Defense Minister Sergei Shoigu about the invasion, Europa Press told Ukraine’s chief intelligence director Vadim Skibitsky.

According to Skibitsky, it was the Russian Federal Security Service (FSB), which is responsible for counterintelligence and espionage work, that put pressure on Gerasimov and other military agencies to agree to launch an offensive. .

However, according to the Ukrainian intelligence services, the FSB considered that by the end of February sufficient preparations had already been made to guarantee the success of the Russian Armed Forces in a lightning invasion.

However, according to Kyiv, the Russian General Staff provided the Russian troops with supplies and ammunition for only three days, hoping that the offensive would be swift and immediately successful.

The head of Ukrainian intelligence also emphasized the cooperation of local residents, who always provided the Ukrainian authorities with up-to-date information about the Russian army, such as the number of soldiers or the exact location of troops.

The military offensive launched on February 24 by Russia in Ukraine caused at least 6.5 million internally displaced persons and more than 7.8 million refugees to European countries, which is why the UN classifies this migration crisis as the worst in Europe since World War II (1939-1945). gg.). ).

At the moment, 17.7 million Ukrainians are in need of humanitarian assistance, and 9.3 million are in need of food aid and housing.

The UN has presented as confirmed 6,755 civilian deaths and 10,607 wounded since the beginning of the war, stressing that these figures are much lower than the real ones.

Life sentence for former Swedish official for spying for Russia

Published

on

A Stockholm court on Monday sentenced a former Swedish intelligence officer to life in prison for spying for Russia, and his brother to at least 12 years in prison. In what is considered one of the most serious cases in Swedish counterintelligence history, much of the trial took place behind closed doors in the name of national security.

According to the prosecution, it was Russian military intelligence, the GRU, who took advantage of the information provided by the two brothers between 2011 and their arrest at the end of 2021.

Peyman Kia, 42, has held many senior positions in the Swedish security apparatus, including the army and his country’s intelligence services (Säpo). His younger brother, Payam, 35, is accused of “participating in the planning” of the plot and of “managing contacts with Russia and the GRU, including passing on information and receiving financial rewards.”

Both men deny the charges, and their lawyers have demanded an acquittal on charges of “aggravated espionage,” according to the Swedish news agency TT.

The trial coincides with another case of alleged Russian espionage, with the arrest of the Russian-born couple in late November in a suburb of Stockholm by a police team arriving at dawn in a Blackhawk helicopter.

Research website Bellingcat identified them as Sergei Skvortsov and Elena Kulkova. The couple allegedly acted as sleeper agents for Moscow, having moved to Sweden in the late 1990s.

According to Swedish press reports, the couple ran companies specializing in the import and export of electronic components and industrial technology.

The man was again detained at the end of November for “illegal intelligence activities.” His partner, suspected of being an accomplice, has been released but remains under investigation.

According to Swedish authorities, the arrests are not related to the trial of the Kia brothers.

Ukraine admitted that Russia may announce a general mobilization

“They can strengthen their positions. We understand that this can happen. At the same time, we do not rule out that they will announce a general mobilization,” Danilov said in an interview with the Ukrainska Pravda online publication.

Danilov believed that this mobilization would also be convened “to exterminate as many as possible” of Russian citizens, so that “they would no longer have any problems on their territory.”

In this sense, Danilov also reminded that Russia has not given up on securing control over Kyiv or the idea of ​​the complete “destruction” of Ukraine. “We have to be ready for anything,” he said.

“I want everyone to understand that [os russos] they have not given up on the idea of ​​destroying our nation. If they don’t have Kyiv in their hands, they won’t have anything in their hands, we must understand this,” continued Danilov, who also did not rule out that a new Russian offensive would come from “Belarus and other territories.” .

As such, Danilov praised the decision of many of its residents who chose to stay in the Ukrainian capital when the war broke out in order to defend the city.

“They expected that there would be panic, that people would run, that there would be nothing to protect Kyiv,” he added, referring to President Volodymyr Zelensky.

The military offensive launched on February 24 by Russia in Ukraine caused at least 6.5 million internally displaced persons and more than 7.8 million refugees to European countries, which is why the UN classifies this migration crisis as the worst in Europe since World War II (1939-1945). gg.). ).

At the moment, 17.7 million Ukrainians are in need of humanitarian assistance, and 9.3 million are in need of food aid and housing.

The Russian invasion, justified by Russian President Vladimir Putin on the need to “denazify” and demilitarize Ukraine for Russia’s security, was condemned by the international community at large, which responded by sending weapons to Ukraine and imposing political and economic sanctions on Russia.

The UN has presented as confirmed 6,755 civilian deaths and 10,607 wounded since the beginning of the war, stressing that these figures are much lower than the real ones.
