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



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.

Understanding the Conflict: Russians Are Increasingly Looking South



Ten points a week to understand what is happening in Eastern Europe and what can change in the life of each of us.


Two children were among the 18 killed in Russian missile attacks on Odessa. Night missile strike of the Black Sea strategic aircraft Tu-22 in the Belgorod-Dnestrovsky district of the Odessa region, three Kh-22 missiles that hit a residential building and a recreation center. Eighteen victims were identified, including two children, 31 people were hospitalized, including four children and a pregnant woman.

However, Ukrainian control of Serpent’s Island is essential to control of the Black Sea, but Russia’s loss may not be permanent.

In what remains of the battle for Donbass, Russia claims to control an oil refinery in Lysichansk. Moscow claims to have seized an oil refinery in Lisichansk; the last major city in the Lugansk region, not captured by Russian troops; offensive in four directions.

Russian troops plant mines in Lysichansk, Ukrainian regional military leader says; these mines, nicknamed “petals”, are extremely dangerous because “they can be placed anywhere, and any child or civilian who goes out in search of humanitarian assistance can step on them and be killed or injured”; The city is being bombed “constantly” day and night, added Serhiy Gaidai, governor of the Luhansk region.


This happened for the first time after the capture of the city by Moscow troops. The destination will be “friendly countries” of Russia.

In Kherson, pro-Russian forces that have illegally occupied the territory are preparing a referendum on unification with Russia. Kirill Stremousov, one of the leaders of the pro-Russian government in Kherson, told Reuters that no date has yet been set for the popular vote, but he expects the referendum to take place “next semester.”

China points out that the war is a consequence of NATO expansion. Beijing has taken to the UN that Russian aggression in Ukraine stems from NATO expansion into Eastern Europe, and criticizes NATO for a “Cold War mentality” and accuses the G7 of “sowing discord.”

Thanks to these positions, cooperation between the US, South Korea and Japan is deepening, which may indicate an “Asian version of NATO.”

However, China is “not providing material support” to the Russian invasion, a senior US official said.


Nearly half of Ukraine’s population is in need of humanitarian assistance – water, food, medical care, shelter and protection (the real number is likely even higher). Sixteen million Ukrainians are at humanitarian risk, and another 5.3 million have fled the country. Perhaps this helps us explain another fact: 89% of Ukrainians reject ceding territory in exchange for peace through negotiations with Russia; 53% believe that the Ukrainian army will push the Russians out of the occupied territories (Wall Street Journal poll).

Russia uses ineffective missiles from former Soviet arsenals in more than 50% of its attacks on Ukraine; this leads to significant loss of life; Over the past two weeks, Russian attacks in Ukraine have more than doubled.


Putin maintains goal of controlling “most of Ukraine,” says a senior US intelligence official: “We remain in a position where we look at President Putin and think that he has essentially the same political goals,” Avril said. Haynes, Director of National Intelligence and former Deputy National Security Adviser during the Obama presidency.
US agencies predict three conflict scenarios in the near future. The possibility of a major Russian offensive or Ukrainian stabilization of the front line are two of the hypotheses under consideration. But the alternative they see as the most likely is a “crushing” conflict in which Russian forces are making only escalating gains but no progress towards Putin’s goal.

Boris Johnson points to the point: “Helping Ukraine is what America has historically done and should do, and it strengthens peace, freedom, and democracy; and if we allow Putin to get away with simply annexing, conquering large parts of a free, independent and sovereign country, which he is about to do… then the consequences for the world will be absolutely disastrous.”

The position of her head of diplomacy is very similar: “It is absolutely necessary that we guarantee the defeat of Russia in Ukraine,” notes Liz Truss. “My message is very strong: first we must defeat Russia, and then negotiate. And this is necessary in the name of European security, freedom and democracy. This is the only way to achieve lasting peace in Europe. Negotiating while Russian troops are still in Ukraine will lead to a false peace and will lead to more aggression in the future. We must learn from the past, such as the failures of the Minsk Protocol, to ensure a lasting peace.”


Before the G-7, the British Prime Minister warned the French President against the temptation to negotiate a settlement in Ukraine, risking prolonging “global instability”.

The entire dominant track record at the G7 and the NATO summit reinforced the British vision, and even more so the French one: unconditional support for Ukraine was in place, and the space for “giving in” to Putin was further reduced.


In response to huge Chinese-funded projects, the G7 decided at a meeting in Germany to allocate $600 billion through 2027 for global infrastructure investment. Regarding G7 investments in the global infrastructure program, the President of the European Commission announced that Europe will provide 300 billion euros.

Canada has sent two warships to the Baltic Sea and the North Atlantic, joining a pair of frigates already in the region in an attempt to reinforce NATO’s eastern flank.

The Canadian ships Kingston and Summerside will embark on a four-month mission as part of “containment measures in Central and Eastern Europe” launched in 2014 following Russia’s annexation of Crimea. Until October, the ships will participate in a maritime mine-clearing exercise that will maintain a “high readiness” that will allow them to “respond quickly and effectively in support of any NATO operations.” HMCS Halifax and Montreal are due to return to port in July from Operation Reassurance, which is currently Canada’s largest overseas deployment.

The mission also includes about 700 Canadian soldiers in Latvia with artillery and electronic equipment, as well as various military aircraft.


This is one of the most resonant phrases in this week’s analysis of Russia’s war in Ukraine. Who said that this is the mother of a girl who worked in a shopping center in Kremenchuk and went missing after a criminal Russian shelling with two rockets.

“We hope that all Russian mothers will feel the same as we do.” Pedro Miguel Costa and Odasir Junior spoke about this in the report.

The first footage of the military after the largest exchange of prisoners between Russia and Ukraine



Ukraine and Russia carried out the largest exchange of prisoners since the beginning of the war. Moscow received 144 soldiers taken prisoner by Ukrainian troops. The same number of captured Ukrainians were repatriated to Kyiv. Among the liberated are soldiers of the Azov regiment, seriously wounded in the battle near Mariupol.

Images released by the Ukrainian Defense Ministry show that nearly all of the 144 POWs released by Russia are seriously injured. They received fractures, amputations, gunshot or shrapnel wounds. Most of all fought in Mariupol.

It is in the Donbass and the last urban bastion of Ukrainian resistance in the east of the country that Russian troops are currently concentrating their offensive. Lisichansk continues to be heavily bombed.

Analysts are already predicting that the conflict will drag on as more Western weapons appear in Ukraine.

Earlier this week, London published photos of Ukrainian soldiers with British military instructors.

On British soil, they learn how to handle the L-119 cannon. They are also being trained to handle the complexities of long-range multiple launch rocket systems capable of hitting targets at a distance of 80 kilometers.

After the United States, and with over €1 billion worth of weapons delivered or pledged, the UK is currently the largest donor of military aid to Ukraine.

The family accepts the cubs, and after 5 days the son dies. “It’s not a coincidence”



UA 14-year-old boy was sentenced to at least 15 years in prison after he killed a five-year-old boy with whom he lived in Wales.

The crime took place days after Craig Mulligan was taken in by the victim’s family, Logan Mwangi. Mwangi’s stepfather had known Mulligan since he was nine months old, and according to international publications, the teenager always idolized him. After the stepfather, 40-year-old John Cole, and the child’s mother, Angharad Williamson, 31, won their foster care case, Mulligan killed Williamson’s son and the body was found about 250 meters from your home on July 31st. .

The child’s injuries have been described as similar to those of a victim of a high-speed crash or a person who has fallen from a height. “Because he was killed at home, it is impossible to be sure what happened”– said the judge.

Despite the identities of the children involved in this type of crime, the judge decided to reveal their identities after a request was made arguing that it was in the public interest to know who the teenager was.

“I have come to the conclusion that after filing, I should remove this restriction”he explained, adding that death came “merciless”as well as “deliberately and organized”.

“They are responsible for Logan’s death and the suffering that followed.”he said, also referring to the child’s mother, who was sentenced to 28 years in prison, and the stepfather, who will serve one more year in prison than the mother.

The teen was 13 years old when he helped Logan’s stepfather dispose of the child’s corpse in the Ogmore River in Bridgend.

Prosecutors in the case described the teenager as a “monster” and said Craig’s arrival “was no accident.”

So far, Craig’s behavior has not been exemplary. In court, the foster family who had previously been in charge of the teenager described her life with him as “hell”adding that they start to get “frightened” with him.

Craig threatened to kill them for weeks, and also threatened to harm the couple’s daughter and their dog, according to the family, quoted by international outlets.

Also according to publications, suspicions about the teenager began when he asked two young women if they would like to play a game “Game of Killing” which included storing them in black bags. The teenager told these same young people, talking about the foster family, that he wanted to “kill the five-year-old.” In court, they were told that Mulligan had a “passion for violence” and that he was a “monster”.

After Logan’s corpse was discovered, the teenager was taken care of by the authorities, and one of the officials heard him say: “I like kids. I love hitting kids on the head. It’s an orgasm.” Another employee said he did “something wrong” but “can’t talk about it.”.

The teenager was taken from his biological mother after she assaulted him, and according to one of the prosecutors, at that time he was already a “complex, troubled and violent” boy. It also became known in court that he suffered from various disorders of neuropsychic development.
