Trump son-in-law Kushner a focus in Russia probe: US media

The Japan government on Monday decided to lift the state of emergency for COVID-19 in Tokyo and four other prefectures of the country, the only places where the measure implemented to curb the pandemic had remained in force.

The lifting of the alert was backed by the coronavirus advisory panel and will be formally approved by the government later day, the economic revitalization minister and head of the working group to coordinate Japan's fight against COVID-19, Yasutoshi Nishimura, said.

The Japanese authorities made the decision after taking into account the number of infections and the situation of the health system in Tokyo, the three neighbouring prefectures of Chiba, Kanagawa and Saitama and the northern Hokkaido, the only ones where the state of emergency declared more than a month ago to control the pandemic remained in effect, reports Efe news.

The health alert was initially declared in Tokyo and six other prefectures on April 17 and subsequently extended across the country.

It allowed local authorities to ban large-scale public events and close bars and restaurants at night, among other measures, while the government has launched a campaign to encourage teleworking and staying at home.

The government resorted to this measure for the first time in the country's recent history to contain the spread of the virus and is now withdrawing it after a sustained slowdown in infections throughout the archipelago, where around 16,600 confirmed COVID-19 cases and 839 deaths have been recorded, according to the latest data.

The group of experts advising the government appreciated the efforts made by citizens to comply with the recommendations to achieve the target of reducing interpersonal contact by 80 percent, top government spokesperson Yoshihide Suga said at a press conference on Monday.

The recommendation for citizens to avoid unnecessary trips outside and the request for non-essential businesses to close were not mandatory nor accompanied by fines or other penalties for non-compliance, unlike the stricter containment measures implemented in other countries.

The government plans to formally approve the lifting of the state of emergency on Monday after consulting with other political parties in parliament and another meeting with the advisory panel, following which Japanese Prime Minister Shinzo Abe will hold a press conference.

The government had already decided to lift the emergency in 39 prefectures on May 14 after they reported a marked decrease in the number of infections, leaving out the more populated regions such as Tokyo and Osaka.

To avoid new outbreaks of the virus, Abe has urged people to become accustomed to a "new lifestyle" that includes maintaining social distancing, the use of masks outside as well as a series of guidelines for the reopening of shops, restaurants and public facilities.

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.

Karachi, May 23: Ninety-seven people were killed and two survived when a passenger plane crashed into homes in Pakistan's southern city of Karachi, health officials said Saturday.

The Pakistan International Airlines (PIA) plane had made multiple approaches to land at the city's airport when it came down in a residential area, damaging buildings and sparking a rescue operation that lasted into the night.

All passengers and crew had been accounted for and the bodies of those killed had been recovered from the crash site, the Sindh Health Ministry said, adding that 19 had been identified.

A local hospital earlier reported it had received the bodies of people killed on the ground.

The site remained cordoned off on Saturday morning.

The crash sent plumes of smoke were into the air as rescue workers and residents searched the debris for people and as firefighters tried to extinguish the flames.

An AFP reporter witnessed charred bodies being loaded into ambulances.

PIA said the plane lost contact with air traffic control just after 2:30 pm (0930 GMT) travelling from Lahore to Karachi.

The disaster comes as Pakistanis prepare to celebrate the end of Ramadan and the beginning of Eid al-Fitr, with many travelling back to their homes in cities and villages.
