Scientists identify six potential drugs to treat Covid19

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.

Kuala Lumpur, Feb 24: Malaysian Prime Minister Mahathir Mohamad has submitted his resignation to the king, two sources with direct knowledge of the matter told Reuters on Monday, amid talks of forming a new coalition to govern the country.

Mahathir, 94, assumed office in May 2018 for his second stint as prime minister.

A spokesman from the prime minister's office declined to comment, saying only that a statement will be issued soon.

The sources declined to be named as they were not authorised to talk to the media.

Washington, Jan 2: The number of people killed in large commercial airplane crashes fell by more than 50% in 2019 despite a high-profile Boeing 737 MAX crash in Ethiopia in March, a Dutch consulting firm said on Wednesday. Aviation consulting firm To70 said there were 86 accidents involving large commercial planes - including eight fatal incidents - resulting in 257 fatalities last year. In 2018, there were 160 accidents, including 13 fatal ones, resulting in 534 deaths, the firm said.

To70 said the fatal accident rate for large airplanes in commercial passenger air transport was just 0.18 fatal accident per million flights in 2019, or an average one fatal accident every 5.58 million flights, a significant improvement over 2018. The fatality numbers include passengers, air crew such as flight attendants and any people on the ground killed in a plane accident

Large passenger airplanes in the study are aircraft used by nearly all travelers on airlines worldwide but excludes small commuter airplanes in service, including the Cessna Caravan and some smaller turboprop airplanes, according to To70.

On Dec. 23, Boeing's board said it had fired Chief Executive Dennis Muilenburg after a pair of fatal crashes involving the 737 MAX forced it to announce it was halting output of its best-selling jetliner. The 737 MAX has been grounded since March after an October 2018 crash in Indonesia and the crash of a MAX in Ethiopia in March killed a total of 346 people.

To70 said the aviation industry spent significant effort in 2019 "focusing on so-called 'future threats' such as drones." But the MAX crashes "are a reminder that we need to retain our focus on the basics that make civil aviation so safe: well-designed and well-built aircraft flown by fully informed and well-trained crews."

The Aviation Safety Network said on Wednesday that, despite the MAX crash, 2019 "was one of the safest years ever for commercial aviation." The 157 people killed in March on Ethiopian Airlines Flight 302 accounted for more than half of all deaths last year worldwide in passenger airline crashes.

Over the last two decades, aviation deaths around the world have been falling dramatically even as travel has increased. As recently as 2005, there were 1,015 deaths aboard commercial passenger flights worldwide, the Aviation Safety Network said.

Last week, 12 people were killed when a Fokker 100 operated by Kazakh carrier Bek Air crashed near Almaty after takeoff. In May, a Russian Sukhoi Superjet 100 aircraft caught fire as it made an emergency landing at Moscow’s Sheremetyevo airport, killing 41 people.

The figures do not include accidents involving military flights, training flights, private flights, cargo operations and helicopters.

From loudspeakers on the roof of a Minnesota mosque, the Islamic call to prayer echoed for the first time ever throughout a Minneapolis neighbourhood late on Thursday as the Muslim community there prepared to begin the holy month of Ramadan.

It echoed again on Friday morning and will continue five times a day during the holy month. 

The simple, short call - known as the adhan - marked an historical moment for Minneapolis and major cities across the United States, community members said. While the adhan is commonly broadcast throughout the Middle East, North Africa and other places, for many Muslims in the US, it is only heard inside mosques or community centres.

"There's definitely a lot of excitement," said Imam Abdisalam Adam, who is on the board of the Dar al-Hijrah mosque, from where the adhan will be broadcast.
"Some people see it as historic," Adam told Al Jazeera. "To the point ... that they're not doing it, able to see it in their lifetime." 

Recited by different representatives from mosques around the city, the call to prayer is expected to reach thousands in the Cedar-Riverside neighbourhood in Minneapolis, according to Jaylani Hussein, the executive director of Minnesota's Council on American-Islamic Relations (CAIR).

While Hussein says the community had discussed broadcasting the call for years, it became even more pressing this year when the coronavirus pandemic forced mosques to shut their doors and residents to stay inside. The coronavirus has infected more than 870,000 people nationwide and killed at least 50,000.
"We wanted to touch those individuals who frequent this mosque and this community," Hussein said. "If we cannot be physically together, at least this echo, this voice, this call to prayer can be an extension of us being together at this difficult time. To give some people some solace."

Ramadan is traditionally a time when Muslims worldwide regularly attend mosques for daily prayers and break their fasts together. But this year, most have been told to pray at home and forgo community iftars in favour of staying safe from the COVID-19 crisis.

Adam, the imam, said while the Muslim community is experience loss this Ramadan, they hope the call to prayer broadcast will create a "semblance of normalcy".

"With the loss of Friday prayers and the regular congregational prayers, we are hoping that this will give a sense of solace and connection to the spiritual needs of community members," he added. 

An avenue to greater investment?

The Cedar-Riverside neighbourhood is a densely populated area of Minneapolis that has historically been an entry point for many immigrants and today is home to large Somali and Oromo communities.

Ramla Bile, a Somali American who lives in a neighbourhood adjacent to Cedar-Riverside, has been active in the community for years. She welcomed the broadcast of the call to prayer, saying it will help people "feel the spirit of Ramadan in a way that is meaningful".

But she also hopes the city of Minneapolis, which provided the noise permit for the broadcast, will make bigger strides to invest in the community in even more tangible ways.

"There's been a lot of need and a lot hurt in the community in light of the COVID-19 pandemic. And then there's the ongoing conversation you've been having," she said, pointing to deep-seated Islamophobia, systemic racism and the need for infrastructure projects like sprinkler systems in high-rise buildings. 

"We need to see greater investments to support the most vulnerable members of our community," Bile said referring to the neighbourhood's elders, undocumented individuals, low-income families and others.

"Right now, we're waiting for a bailout for our micro-businesses who comprise our Somali malls, or a rent freeze for neighbourhood residents," she added.

For CAIR's Hussein and Imam Adam, they hope this Ramadan's call to prayer helps encourage other communities around the US to take similar steps.

"This will hopefully inspire others … to think about what could happen in future Ramadans and beyond," Hussein said.

Adam added that while the virus has devastated communities and upended daily life, it has also shown that "we're in this together".

"It just shows the significance of the global village and how interconnected and interdependent we are as a world community," he said. "I think that there will be a lot of change in our way of life for the better. I hope so."
