1. DCGI grants marketing authorization to SII's qHPV Vaccine

Tags: Science and Technology

The Drugs Controller General of India (DCGI) granted market authorisation to Serum Institute of India (SII) to manufacture India’s first Quadrivalent Human Papillomavirus vaccine (qHPV) which is indigenously developed against cervical cancer. 

Important facts

  • qHPV is the first indigenous vaccine developed in India against cervical cancer which is likely to be launched by the end of this year.

  • It will be an Indian vaccine for the treatment of cervical cancer in women that is both affordable and accessible.

What is Cervical Cancer?

  • Cervical cancer starts in the cells of the cervix, the lower part of the uterus. 

  • The cervix connects the body of the uterus to the vagina. 

  • Cancer starts when cells in the body grow out of control.

  • Most cases of cervical cancer are caused by infection of the human papillomavirus (HPV), which is preventable with a vaccine.

  • Cervical cancer grows slowly, so it usually has time to be detected and treated before it causes serious problems.

  • Women between the ages of 35 and 44 are most likely to get this disease.

Drugs Controller General of India (DCGI)

  • It comes under the Central Drugs Standard Control Organization (CDSCO).

  • It is responsible for approval of licences of specified categories of drugs like blood and blood products, vaccines, IV fluids and sera in India.

  • It sets the standards and quality of the manufacture, sale, import and distribution of drugs in India.

2. Indian scientists develop novel mechanism to inactivate SARS-CoV-2

Tags: Science and Technology

Indian  Scientists have developed an innovative system to inactivate the SARS-CoV-2 virus by preventing the entry of the SARS-CoV-2 virus into the cells of the body, reducing its infection capacity.

Important facts 

  • For this, the researchers have informed about the design of a new class of synthesized peptides.

  • This peptide can not only inhibit the entry of SARS-CoV-2 virus into cells, but can also entangle virus particles together in a manner that reduces their ability to infect.

  • This new effort provides an alternative mechanism to inactivate viruses such as SARS-CoV-2 and  promises a new class of peptides as antivirals.

  • The research was supported under the COVID-19 IRPHA call of the Science and Engineering Research Board (SERB), a statutory body of the Department of Science and Technology (DST).

What is the new innovative system?

  • The developed peptides are helical and hairpin-like in shape.

  • Each of these is able to associate with another of its kind, which is known as a dimmer.

  • Each dimeric 'bundle' presents two surfaces for interaction with the two target molecules.

  • Scientists from the Indian Institute of Science, in collaboration with researchers from the CSIR-Institute of Microbial Technology, have taken advantage of this approach to design these peptides.

  • The team of researchers used a peptide called SIH-5 to target the interaction between the SARS-CoV-2 receptors of SARS-CoV-2's spike(S) protein and SARS-CoV-2's ACE2 protein in human cells.

What is the sars-cov-2 virus?

  • It is responsible for causing the coronavirus disease (Covid-19).

  • SARS means Severe Acute Respiratory Syndrome.

  • For the first time in 2019, it was reported that SARS-CoV-2 can infect people as well.

  • It is believed that the virus spreads from person to person through droplets released when an infected person coughs, sneezes or talks.

  • Coronaviruses are a specific family of viruses, some of which cause less-severe damage, such as the common cold, while others cause respiratory and intestinal diseases.

10. Three new Exotic subatomic particles discovered with the Large Hadron Collider

Tags: Science and Technology

The Large Hadron Collider beauty (LHCb) experiment has  discovered three never-before-seen particles.

  • What is the discovery?

  • CERN, (European Organization for Nuclear Research) was investigating the slight differences between matter and antimatter by studying a type of particle called the “beauty quark”, or “b quark”.

  • The three “exotic” particles, a new kind of “pentaquark” and the first-ever pair of “tetraquarks” were found.

  • These are a kind of new hadrons.

  • The discovery will help physicists understand how quarks bind together in these composite particles.

  • What are Quarks?

  • Quark is a fundamental component of matter and is defined as an elementary particle.

  • These quarks combine to produce composite particles called hadrons.

  • They usually combine together in groups of twos and threes to form hadrons.

  • The most stable of these are neutrons and protons which are components of the atomic nucleus.

  • They can also combine into four-quark and five-quark particles, called tetraquarks and pentaquarks.

  • These exotic hadrons were predicted by theorists nearly six decades ago.

  • Tetraquarks and Pentaquarks

  • Atoms contain smaller particles called neutrons and protons, which are made up of three quarks each.

  • Most of the exotic hadrons discovered in the past two decades are tetraquarks or pentaquarks.

  • They contain a charm quark and a charm antiquark.
