May 19: A Chinese laboratory has been developing a drug it believes has the power to bring the coronavirus pandemic to a halt.

The outbreak first emerged in China late last year before spreading across the world, prompting an international race to find treatments and vaccines.

A drug being tested by scientists at China's prestigious Peking University could not only shorten the recovery time for those infected, but even offer short-term immunity from the virus, researchers say.

Sunney Xie, director of the university's Beijing Advanced Innovation Center for Genomics, told AFP that the drug has been successful at the animal testing stage.

"When we injected neutralising antibodies into infected mice, after five days the viral load was reduced by a factor of 2,500," said Xie.

"That means this potential drug has (a) therapeutic effect."

The drug uses neutralising antibodies -- produced by the human immune system to prevent the virus infecting cells -- which Xie's team isolated from the blood of 60 recovered patients.

A study on the team's research, published Sunday in the scientific journal Cell, suggests that using the antibodies provides a potential "cure" for the disease and shortens recovery time.

Xie said his team had been working "day and night" searching for the antibody.

"Our expertise is single-cell genomics rather than immunology or virology. When we realised that the single-cell genomic approach can effectively find the neutralising antibody we were thrilled."

He added that the drug should be ready for use later this year and in time for any potential winter outbreak of the virus, which has infected 4.8 million people around the world and killed more than 315,000.

"Planning for the clinical trial is underway," said Xie, adding it will be carried out in Australia and other countries since cases have dwindled in China, offering fewer human guinea pigs for testing.

"The hope is these neutralised antibodies can become a specialised drug that would stop the pandemic," he said.

China already has five potential coronavirus vaccines at the human trial stage, a health official said last week.

But the World Health Organization has warned that developing a vaccine could take 12 to 18 months.

Scientists have also pointed to the potential benefits of plasma -- a blood fluid -- from recovered individuals who have developed antibodies to the virus enabling the body's defences to attack it.

More than 700 patients have received plasma therapy in China, a process which authorities said showed "very good therapeutic effects".

"However, it (plasma) is limited in supply," Xie said, noting that the 14 neutralising antibodies used in their drug could be put into mass production quickly.

Using antibodies in drug treatments is not a new approach, and it has been successful in treating several other viruses such as HIV, Ebola and Middle East Respiratory Syndrome (MERS).

Xie said his researchers had "an early start" since the outbreak started in China before spreading to other countries.

Ebola drug Remdesivir was considered a hopeful early treatment for COVID-19 -- clinical trials in the US showed it shortened the recovery time in some patients by a third -- but the difference in mortality rate was not significant.

The new drug could even offer short-term protection against the virus.

The study showed that if the neutralising antibody was injected before the mice were infected with the virus, the mice stayed free of infection and no virus was detected.

This may offer temporary protection for medical workers for a few weeks, which Xie said they are hoping to "extend to a few months".

More than 100 vaccines for COVID-19 are in the works globally, but as the process of vaccine development is more demanding, Xie is hoping that the new drug could be a faster and more efficient way to stop the global march of the coronavirus.

"We would be able to stop the pandemic with an effective drug, even without a vaccine," he said.

Washington, Jan 12: US president Donald Trump said Saturday the United States was monitoring Iranian demonstrations closely, warning against any new “massacre” as protests broke out after Tehran admitted to shooting down a passenger plane.

Iran said earlier it unintentionally downed a Ukrainian jetliner outside Tehran, killing all 176 people aboard, in an abrupt about-turn after initially saying that it had crashed due to mechanical failure. The firing came shortly after Iran launched missiles at bases in Iraq housing American forces.

President Hassan Rouhani said a military probe into the tragedy had found that “missiles fired due to human error” brought down the Boeing 737, calling it an “unforgivable mistake.”

Trump told Iranians -- in tweets in both English and Farsi -- that he stands by them and is monitoring the demonstrations.

“To the brave, long-suffering people of Iran: I've stood with you since the beginning of my Presidency, and my Administration will continue to stand with you,” he tweeted.

“There can not be another massacre of peaceful protesters, nor an internet shutdown. The world is watching,” he added, apparently referring to an Iranian crackdown on street protests that broke out in November.

“We are following your protests closely, and are inspired by your courage," he said.

The new demonstrations follow an Iranian crackdown on street protests that broke out in November. Amnesty International has said it left more than 300 people dead. Internet access was reportedly cut off in multiple Iranian provinces ahead of memorials planned a month after the protests.

On Saturday evening, police dispersed students who had converged on Amir Kabir University in Tehran to pay tribute to the victims, after some among the hundreds gathered shouted "destructive" slogans, Fars news agency said.

State television reported that students shouted "anti-regime" chants, while the news agency Fars reported that posters of Soleimani had been torn down.

London, May 9: Air India's first evacuation flight from London will be taking off for Mumbai today.

The screening of passengers is underway.

"Air India's first evacuation flight from London taking off for Mumbai today at 1200. Flight is 100% booked! Shubh Yatra. Please stay in touch. GoI working to send more evacuation flights!" High Commission of India, London said in a tweet.

On Monday, India announced had that it will begin phased repatriation of its citizens stranded abroad from May 7.

The government said that Air India will operate 64 flights in the first week from May 7 to May 13 to bring back around 15,000 Indian nationals.

On day three of the 'Vande Bharat Mission', flights carrying Indians from the Gulf countries, the United Kingdom, Bangladesh and Malaysia will arrive in India.
