Most people to be naturally armed against covid-19: Study

Jerusalem, Feb 12: The majority of the people can produce neutralising antibodies against the novel coronavirus in severe cases of Covid-19, according to a study that supports the use of combination antibody therapy to prevent and treat the disease.

The researchers noted that neutralising antibodies that specifically target the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein -- which the virus uses to enter human cells -- are thought to be essential for controlling it.

RBD-specific neutralising antibodies have been detected in convalescent patients -- those who have recovered from Covid-19, according to the team, including researchers from Tel Aviv University in Israel.

Some of the recovered patients tend to have robust and long-lasting immunity, while others display a waning of their neutralising antibodies, they said.

The study, published in the journal PLOS Pathogens, used molecular and bioinformatics techniques to compare B-cell responses in eight patients with severe Covid-19 and 10 individuals with mild symptoms, 1.5 months after infection.

B cells of immune system are responsible for mediating the production of antigen-specific immunoglobulin (Ig) directed against invasive pathogens.

The research found that very ill patients showed higher concentrations of RBD-specific antibodies and increased B-cell expansion.

Among 22 antibodies cloned from two of these patients, six exhibited potent neutralisation against SARS-CoV-2, the researchers said.

"Bioinformatics analysis suggests that most people would be capable of readily producing neutralising antibodies against SARS-CoV-2 in severe cases of Covid-19," they noted.

Moreover, the study shows that combinations of different types of neutralising antibodies completely blocked the live virus from spreading.

According to the researchers, these antibody cocktails can be further tested in clinical settings as a useful means to prevent and treat Covid-19.

"Even with a vaccine at our doorstep, arming clinicians with specific anti-SARS-CoV-2 therapeutics is extremely important," the researchers said.

"Combinations of neutralising antibodies represent a promising approach towards effective and safe treatment of severe Covid-19 cases, especially in the elderly population or chronically ill people, who will not be able to so easily produce these antibodies upon infection or vaccination," they added.

Prominent NRI community leader SM Syed Khalilur Rehman, fondly known as CA Khalil, passed away in Dubai on Thursday at the age of 86 after a brief illness.

Khalil had been admitted to Aster Hospital in Mankhool on Tuesday after experiencing severe leg weakness. Despite the best efforts of the medical team, he succumbed to a double heart attack that worsened his condition, his son Rais Ahmed confirmed.

The news of his passing has sent waves of grief across communities, particularly in his hometown of Bhatkal, Karnataka, where he was a celebrated figure. Tributes have been pouring in on social media, highlighting his significant contributions to international trade, social service, and education.

A Legacy of Leadership and Service

A chartered accountant by profession, Khalil was a founding member of the Dubai chapter of the Institute of Chartered Accountants of India (ICAI), where he served as chairman from 1987 to 1994. His illustrious career included key leadership roles, such as general manager of Khaleej Times, group executive director of the Ilyas and Mustafa Galadari Group, and vice-chairman of the Jashanmal Group of Companies.

He also chaired Maadhyama Communications and Sahil Online, a web-based news platform, and was a director and trustee of several media companies and charitable organisations in Dubai and India.

A Champion for Education and Philanthropy

Khalil’s impact extended far beyond his professional achievements. As president and general secretary of Anjuman Hami-e-Muslimeen, he played a pivotal role in the development of educational institutions, including schools and colleges in Bhatkal and surrounding areas. His dedication to social upliftment earned him recognition from the Government of Karnataka, which honoured him with a prestigious award for his philanthropic contributions.

A Life Celebrated

The Bhatkal Muslim Khaleej Council (BMKC) recently released a documentary celebrating Khalil’s remarkable life and service to the community—a testament to his enduring legacy.

CA Khalil is survived by his family and countless admirers across the globe. His passing marks the end of an era for Indian expatriates in the UAE and beyond, leaving behind a legacy of leadership, generosity, and commitment to community service.

Shares of Adani Group companies lost about $28 billion in market value in morning trade on Thursday after US prosecutors charged the billionaire chairman of the Indian conglomerate in an alleged bribery and fraud scheme.

Gautam Adani's flagship company Adani Enterprises tumbled 23 per cent, while Adani Ports, Adani Total Gas, Adani Green, Adani Power, Adani Wilmar and Adani Energy Solutions, ACC , Ambuja Cements and NDTV fell between 20 per cent and 90 per cent.

Adani group's 10 listed stocks had a total market capitalisation of about $141 billion at 0534 GMT, compared to $169.08 billion on Tuesday.

US authorities said Adani and seven other defendants, including his nephew Sagar Adani, agreed to pay about $265 million in bribes to Indian government officials to obtain contracts expected to yield $2 billion of profit over 20 years, and develop India's largest solar power plant project.

Adani Green in a statement on Thursday said the US Justice Department had issued a criminal indictment against board members Gautam Adani and Sagar Adani and the Securities and Exchange Commission had issued a civil complaint against them.

The US Justice Department also included Adani Green board member Vneet Jaain in the criminal indictment, it said.

Adani Green's units had decided not to proceed with the proposed US dollar denominated bond offerings due to developments, it added.

"Investors will shy away from Adani Group stocks ... and that's what this sharp selling is signifying," said Saurabh Jain, assistant vice president of retail equities research at SMC Global Securities.

"This could hurt the credibility of the group and maybe borrowing costs will rise," he said.

The indictment comes nearly two years after US shortseller Hindenburg Research alleged that Adani had improperly used tax havens and was involved in stock manipulation, allegations the conglomerate denied.

Also in early Asian trading on Thursday, Adani dollar bonds slumped, with prices down 3c-5c on bonds for Adani Ports and Special Economic Zone. The falls were the largest since the Adani Group came under a short-seller attack in February 2023.

An Israeli airstrike on the office of Syria’s Baath party in Lebanon’s capital Beirut has killed the Lebanese resistance movement Hezbollah's Media Relations Officer, Mohammad Afif, reports say.

Lebanon's National News Agency (NNA) reported that the Israeli raid struck the Ba'ath party’s building in central Beirut district of Ras Al-Naba'a on Sunday, adding that the strike was an attempt to assassinate the leader of the resistance media front.

According to Baath Secretary-General Ali Hijazi, Afif was having a meeting in the Baath Party headquarters when Israel carried out the attack.

"Afif did not fight with weapons and did not lead a military unit in Hezbollah. Rather, he led a media unit," he said.

Reuters, Sky News, Al Jazeera and a number of Henrew-language media reported that Afif was killed in the Israeli strike.

However, Hezbollah has not yet confirmed Afif’s death or whether he was present at the site or not.

Earlier, the Lebanese Health Ministry said at least one person was killed and three others injured after an Israeli strike targeted a central district in Beirut.

Lebanon's al-Mayadeen television network reported that five people were killed in the attack.

The latest development came after Afif said Hezbollah was behind the Caesarea operation and targeting Netanyahu’s home during a speech at the Ghobeiry area in the southern suburbs of Beirut on October 22.

This was the second assassination attempt on Afif in the last two months, after he survived an attack on the Hezbollah media relations office several weeks ago.

Israel launched a ground assault and massive air campaign against Lebanon in late September after a year of exchanging fire across the Lebanese border in parallel with the Gaza war.

At least 3,287 people have been killed in Israeli strikes in Lebanon over the past year, with the vast majority in the past seven weeks. Another 14,222 have been wounded, mostly women and children.

In response to the ongoing aggression, the Lebanese resistance movement Hezbollah has been staging hundreds of retaliatory strikes against the occupied Palestinian territories and the Israeli forces trying to advance on southern Lebanese areas.

The movement has vowed to sustain its strikes until the regime ends the escalation.
