Five killed in bomb attack on Colombia police station

Beijing, June 30: China said on Tuesday it was concerned about India’s decision to ban Chinese mobile apps such as Bytedance’s TikTok and Tencent’s WeChat and was making checks to verify the situation.

Chinese foreign ministry spokesman Zhao Lijian told reporters during a daily briefing that (the Prime Minister Narendra Modi-led government of) India has a responsibility to uphold the rights of Chinese businesses.

India on Monday banned 59, mostly Chinese, mobile apps in its strongest move yet targeting China in the online space since a border crisis erupted between the two countries this month.

The apps are “prejudicial to the sovereignty and integrity of India, the defence of India, the security of state and public order", the ministry of information technology said in a statement, which came two weeks after 20 Indian Army personnel were killed in a violent clash on the India-China border in Ladakh.

The companies have been invited to offer clarifications before a government panel, which will decide whether the ban can be removed or will stay.

The move also came ahead of military and diplomatic talks between India and China scheduled this week.

Islamabad, May 7: Pakistan's COVID-19 cases have crossed 24,000 after 1,523 new infections were detected, while the death toll has jumped to 564 with 38 more people succumbing to the coronavirus, health officials said on Thursday.

Even as the country is seeing an increase in the number of coronavirus cases and fatalities, Prime Minister Imran Khan will discuss the easing of lockdown restrictions with his top aides on Thursday.

The Ministry of National Health Services said that out of the 24,073 total cases, Punjab reported 9,077, Sindh 8,640, Khyber-Pakhtunkhwa 3,712, Balochistan 1,495, Islamabad 521, Gilgit-Baltistan 388 and Pakistan-occupied Kashmir 76 cases.

After 38 more deaths on Wednesday, the total coronavirus patient death toll jumped to 564. Another 6,464 have recovered. A total of 1,523 new patients were added in a single day, the ministry.

So far, 244,778 tests have been conducted, including 12,196 in the last 24 hours, it said.

Prime Minister Khan will chair the National Coordination Committee (NCC) meeting on easing the lockdown restrictions in the country. The meeting will be attended by all chief ministers.

The issue was debated in the National Command and Operation Centre (NCOC) on Wednesday and in the Cabinet on Tuesday.

Planning Minister Asad Umar said that different proposals to allow certain businesses to open were prepared and will be presented before the Prime Minister for a final decision.

Earlier, Khan, undeterred by the mounting number of deaths and the new cases, announced that he was against a lockdown as it hits the poor people badly.

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.
