Chloroquine

      HEADLINES:

Chloroquine does not inhibit SARS-CoV-2 spread in human lung cells: Study

      WHY IN NEWS:

In a recent study is to be believed, however, chloroquine has been found ineffective as a preventive cure.

SYLLABUS COVERED: GS 3:Health:Diseases

      ISSUE: 

The drug stops the spread of the virus that causes COVID-19 in African green monkey kidney cells, but is ineffective in human lung cells

STUDIED BY

German Primate Center (DPZ) at Leibniz Institute.

STUDY ANALYSIS

  • The anti-viral activity of chloroquine is cell type-specific and does not block the infection of lung cells.
  • The SARS-CoV-2 virus uses two different routes to enter cells.

HOW COVID-19 ENTERS HUMAN BODY

  • One route is for the virus to fuse directly with the plasma membrane of the cell .
  • Another route is for the virus to reach the interior of the cells upon uptake through endosomes (transport structures).

Once entered then in turn, the virus introduces its genetic material to the host cell.

SPIKE PROTEIN

  • The viral spike protein of the SARS-CoV-2, in both cases, is responsible for its attachment to cells.

This spike protein uses two types of enzymes to activate itself: Cathepsin L (found in endosomes) and TMPRSS2 (on cell surfaces).

  • The activation can be done either by both or one of the enzymes.
  • Chloroquine — in the monkey cells — inhibits the virus’ entry, most likely by blocking Cathepsin L.

BACKGROUND

The absence of a vaccine has prompted a global search for a preventive cure, with chloroquine — a drug used to treat malaria.

  • Chloroquine has also often been touted by world leaders.Ex :President Donald Trump — who said that he was taking the drug as a preventive measure.
  • In March, the ICMR gave its assent for using the drug under exceptional circumstances.

      IASbhai WINDUP: 

This means care should be taken for using relevant cell lines to not waste unnecessary time and resources in our search for testing effective COVID-19 therapeutics.

  • COVID-19 is primarily caused by the infection of lung cells.
  • For this reason, these cells should be given priority in efficacy tests.

200 Proposals from China on hold

      HEADLINES:

200 proposals from China wait for security clearance by MHA

      WHY IN NEWS:

New investment policy is aimed at preventing hostile action amid pandemic

SYLLABUS COVERED: GS 2 : 3 : FDI

      ISSUE: 

About 200 investment proposals from China are awaiting security clearance from the Ministry of Home Affairs (MHA) after new rules were notified in April

  • Making prior government approval mandatory for foreign direct investments (FDI) from countries which share a land border with India.
  • As FDI is allowed in non-critical sectors through the automatic route, earlier these proposals would have been cleared without the MHA’s nod.

27th July Current Affairs News Analysis | Prelims & Mains 2020

REVISED IN APRIL

  • The Department for Promotion of Industry and Internal Trade (DPIIT) notified the new FDI policy on April 18.
  • An entity of a country, can invest only under the Government route.

The revised FDI policy is aimed at curbing opportunistic takeovers/acquisitions of Indian companies due to the current COVID-19 pandemic.

MAY PULL OUT

  • However, none of the proposals have been cleared so far.
  • It is possible that many might withdraw due to the delay or stringent conditions put in place now.

      IASbhai WINDUP: 

Investors from countries that are not covered by revised FDI new policy only have to inform the Reserve Bank of India after the completion of a transaction rather than seek prior clearance from the administrative ministry.

Tsirkon (Zircon) hypersonic cruise missile

      HEADLINES:

Russian Navy will soon get hypersonic n-weapons

      WHY IN NEWS:

Putin Navy will get 40 new vessels this year

SYLLABUS COVERED: GS 3: Defence

      ISSUE: 

Russian President Vladimir Putin said on Sunday that the Russian Navy would be armed with hypersonic nuclear strike weapons and underwater nuclear drones.

TSIRKON (ZIRCON) HYPERSONIC CRUISE MISSILE

  • Tsirkon (Zircon) hypersonic cruise missile can be deployed on surface ships.

The combination of speed, manoeuvrability and altitude of hypersonic missiles, capable of travelling at more than five times the speed of sound, makes them difficult to track and intercept.

  • The Zircon missile is strategically valuable due primarily to its speed.
  • It was reported that the Zircon had reached a speed of Mach 8 during a test.
  • Another valuable aspect of the missile is its plasma cloud.
  • During flight, the missile is completely covered by a plasma cloud that absorbs any rays of radio frequencies and makes the missile invisible to radars.
  • This allows the missile to remain undetected on its way to the target.

      IASbhai WINDUP: 

The weapons, some of which have yet to be deployed, include the Poseidon underwater nuclear drone, designed to be carried by submarines.
