‘US lied about bin Laden compound raid'

Paris, Apr 9: More than 1.5 million cases of the novel coronavirus have been registered worldwide, according to a tally compiled by AFP at 0530 GMT Thursday from official sources.

Of the 1,502,478 infections, 87,320 people have died across 192 countries and territories since the epidemic first emerged in China late last year.

The tallies, using data collected by AFP from national authorities and information from the World Health Organization (WHO), probably reflect only a fraction of the actual number of infections. Many countries are only testing the most serious cases.

Karachi, Jun 22: India-born renowned Pakistani Shia scholar and author Talib Jauhari passed away here after a prolonged illness. He was 80.

Jauhari, who was born on August 27, 1939 in Patna, is survived by his three sons, Dawn News reported on Monday.

He migrated to Pakistan along with his father in 1949, two years after the Partition.

After obtaining early education from his father, he went to Iraq where he studied religion for 10 years under the renowned Shia scholars of that time.

Jauhari, who was on a ventilator in the intensive care unit of a private hospital for the past 15 days, breathed his last on Sunday night.

His son Riaz Jauhari confirmed his death and said that the body has been shifted to Ancholi Imambargah for the funeral prayers, The Express Tribune newspaper quoted his son as saying.

Jauhari was respected among his sect as he was a class fellow of the widely revered scholar Ayatollah Sayyid Ali al-Husayni al-Sistani.

He was also a poet, historian and philosopher and authored many books.

Pakistan Prime Minister Imran Khan has condoled Jauhari's death.

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.
