Thiruvananthapuram, April 19, 2017: A component of the skin mucus secreted by a frog species found in India can be harnessed to kill influenza viruses, new research has found.

In their experiment, the researchers found that when delivered intranasally, one of the antiviral peptides found in skin secretions from the Indian frog Hydrophylax bahuvistara can kill H1 variety of influenza viruses that can affect humans.

The research, carried out by researchers from Emory University in the US and Rajiv Gandhi Centre for Biotechnology in Thiruvananthapuram, also showed that the compound can protect unvaccinated mice against a lethal dose of some flu viruses.

The researchers believe that the compound has the potential to contribute to first-line anti-viral treatments during influenza outbreaks.

Frogs’ skins were known to secrete “host defense peptides” that defend them against bacteria.

The new finding, published in the journal Immunity, suggests that the peptides represent a resource for antiviral drug discovery as well.

 Anti-flu peptides could become handy when vaccines are unavailable, in the case of a new pandemic strain, or when circulating strains become resistant to current drugs, said senior author Joshy Jacob, Associate Professor of Microbiology and Immunology at Emory Vaccine Center and Emory University School of Medicine in in Atlanta, Georgia, US.

Jacob and his colleagues named the antiviral peptide they identified urumin, after a whip-like sword called “urumi” used in southern India centuries ago.

Urumin was collected for the study after mild electrical stimulation of the frog.

Peptides are short chains of amino acids, the building blocks of proteins. Some anti-bacterial peptides work by punching holes in cell membranes, and are thus toxic to mammalian cells, but urumin was not.

Instead, urumin appeared to only disrupt the integrity of flu virus, as seen through electron microscopy.

It binds the stalk of hemagglutinin, a less variable region of the flu virus that is also the target of proposed universal vaccines, the study said.

This specificity could be valuable because current anti-influenza drugs target other parts of the virus, Jacob said.

Urumin was specific for H1 strains of flu, such as the 2009 pandemic strain, and was not effective against other current strains such as H3N2, the study pointed out. (IANS)

The program is inseparable from Mahalaya and has been going on for over six decades till date. The magic is induced by the popular Birendra Krishna Bhadra whose voice makes the recitation of the “Chandi Kavya” even more magnificent! He has been a legend and the dawn of Mahalaya turns insipid without the reverberating and enchanting voice of the legendary man.

Mahalaya will keep spreading the magic and setting the vigor of the greatest festival of the Bengalis- the Durga Puja, to worship the supreme Goddess, eternally.

June 06, 2017: NASA has chosen 12 astronauts out of a record-breaking 18,300 applications for upcoming space missions. An American of Indian descent, Raja Chari, has successfully earned his spot in the top 12.

The astronauts were selected on the basis of expertise, education, and physical tests. This batch of 12 astronauts is the largest group selected by NASA since two decades. The group consisting of 7 men and 5 women surpassed the minimum requirements of NASA.

Born in Waterloo, Iowa, Chari graduated from Air Force Academy in 1999 with a bachelor’s degree in Astronautical Engineering and Engineering Science. He went on to complete his master’s in Aeronautics and Astronautics from Massachusetts Institute of Technology. The astronaut is also a graduate of US Naval Test Pilot School.

Currently, Raja Chari is a Lieutenant Colonel in the US Air Force. He is the commander of 461st Flight Test Squadron and director of the F-35 Integrated Test Force at Edwards Air Force Base in California.

After Late Kalpana Chawla, Lt. Col. Raja Chari is the second Indian American astronaut chosen by NASA.

The 12 astronauts will have to go through two years of training. Upon completion, they will be assigned their missions ranging from research at the International Space Station, launching from American soil on spacecraft by private companies, to flying on deep space missions on NASA’s Orion Spacecraft.

The US Vice-President Mike Pence visited the Johnson Space Centre in Houston to announce and congratulate the new batch. Pence also said that President Trump is “fully committed” to NASA’s missions in space.
