Will order investigation into visa abuses: Trump

Washington, Jun 1: As protesters gathered outside the White House on Friday night in Washington DC, US President Donald Trump was briefly taken to the White House underground bunker, The New York Times reported citing a person having firsthand knowledge about the incident.

Trump was there for less than an hour before being brought upstairs. After hundreds of people surged towards the White House on Friday, Secret Service and the United States Park Police officers sought to block them.

Trump's team was surprised by the protests that were witnessed outside the White House on Friday night, according to the US daily. It is, however, unclear if Melania Trump and Barron Trump were also taken down with him.

in response to the continuing protests against the death of African-American man George Floyd in police custody.

National Guard members have been activated in 15 states and Washington, DC with another 2,000 prepared to activate if needed.

Demonstrators across the United States have been protesting since May 25, when George Floyd, a 46-year-old African-American man, died under the police custody in the city of Minneapolis.

Washington, Apr 17: A record number of 4,591 Americans have died in the last 24 hours due to the deadly novel coronavirus in the US, which has the highest number of COVID-19 casualties in the world.

According to the Johns Hopkins University data, by 8 pm on Thursday, as many as 4,591 Americans have died in the last 24 hours, The Wall Street Journal said.

The previous highest was 2,569 on Wednesday.

By Thursday, more than 662,000 Americans tested positive with the coronavirus.

The dreaded disease, which originated in Wuhan city in China in December last year, has so far claimed more than 144,000 lives and infected over 2.1 million people.

The virus has infected over 671,000 people and claimed more than 33,000 lives, the highest for any country in the world.

New York City and its adjoining areas, including New Jersey and Connecticut have emerged as the epicenter of the virus in the US.

New York alone accounts for 226,000 cases of infections and 16,106 deaths.

In New Jersey, as many as 3,518 people have died of the disease and 75,317 have tested positive.

According to the US Centers for Disease Control and Prevention, till April 14, four per cent of the Americans infected with COVID-19 were of Asian origin and nearly one-third (30 per cent) were African Americans.

US President Donald Trump told reporters at the White House that experts and scientists report that his strategy to slow the spread of the virus has saved hundreds of thousands of lives.

Models predicted between 1.5 million and 2.2 million US deaths. If there was no mitigation, it could have even been higher than that and between 100,000 and 240,000 deaths with mitigation. It is looking like we will come far under even these lowest numbers, he said.

Noting that experts say the curve of the virus has flattened, and the peak in the new cases has passed, Trump said that nationwide, more than 850 counties or nearly 30 per cent of the country have reported no new cases in the last seven days.

Because of our early and aggressive action, we have avoided the tragedy of health care rationing and deadly shortfalls that have befallen in many other nations, nations which wherever possible we are helping, he said.

According to Trump, at least 35 clinical trials are already underway, including antiviral therapies, immune therapies, and blood therapies in the form of convalescent plasma. So far, more than 3.5 million tests have been carried out.

Melbourne, Apr 10: Scientists have identified six drug candidates from more than 10,000 compounds that may help treat COVID-19.

The research, published in the journal Nature, tested the efficacy of approved drugs, drug candidates in clinical trials and other compounds.

"Currently there are no targeted therapeutics or effective treatment options for COVID-19," said Professor Luke Guddat from the University of Queensland in Australia.

"In order to rapidly discover lead compounds for clinical use, we initiated a programme of high-throughput drug screening, both in laboratories and also using the latest computer software to predict how different drugs bind to the virus," Guddat said.

The project targeted the main COVID-19 virus enzyme, known as the main protease or Mpro, which plays a pivotal role in mediating viral replication, the researchers said.

This makes it an attractive drug target for this virus, and as people don't naturally have this enzyme, compounds that target it are likely to have low toxicity, they said.

"We add the drugs directly to the enzyme or to cell cultures growing the virus and assess how much of each compound is required to stop the enzyme from working or to kill the virus. If the amount is small, then we have a promising compound for further studies," said Guddat.

After assaying thousands of drugs, researchers found of the six that appear to be effective in inhibiting the enzyme, one is of particular interest.

"We're particularly looking at several leads that have been subjected to clinical trials including for the prevention and treatment of various disorders such as cardiovascular diseases, arthritis, stroke, atherosclerosis and cancer," Guddat said.

Researchers said compounds that are already along the pipeline to drug discovery are preferred, as they can be further tested as antivirals at an accelerated rate compared to new drug leads that would have to go through this process from scratch.

"With continued and up-scaled efforts we are optimistic that new candidates can enter the COVID-19 drug discovery pipeline in the near future," Guddat said.
