Green tea has five tested chemical compounds that bind to different sites. Pixabay

In a unique study, researchers have claimed that chemical compounds in foods or beverages like green tea, muscadine grapes, and dark chocolate can bind to and block the function of a particular enzyme, or protease, in the SARS-CoV-2, the virus responsible for Covid-19.

“Proteases are important to the health and viability of cells and viruses. If proteases are inhibited, cells cannot perform many important functions – like replication, for example,” said study author De-Yu Xie from the North Carolina State University in the US.

“One of our lab’s focuses is to find nutraceuticals in food or medicinal plants that inhibit either how a virus attaches to human cells or the propagation of a virus in human cells,” Xie added.

In the study, published in the journal Frontiers in Plant Science, the research team performed both computer simulations and lab studies showing how the so-called “main protease” (Mpro) in the SARS-CoV-2 virus reacted when confronted with a number of different plant chemical compounds already known for their potent anti-inflammatory and antioxidant properties.

“Mpro in SARS-CoV-2 is required for the virus to replicate and assemble itself. If we can inhibit or deactivate this protease, the virus will die,” Xie said.

Computer simulations showed that the studied chemical compounds from green tea, two varieties of muscadine grapes, cacao powder, and dark chocolate were able to bind to different portions of Mpro.

“Mpro has a portion that is like a ‘pocket’ that was ‘filled’ by the chemical compounds. When this pocket was filled, the protease lost its important function,” Xie explained. Lab experiments also showed similar results. The chemical compounds in green tea and muscadine grapes were very successful at inhibiting Mpro’s function; chemical compounds in cacao powder and dark chocolate reduced Mpro activity by about half.

“Green tea has five tested chemical compounds that bind to different sites in the pocket on Mpro, essentially overwhelming it to inhibit its function,” Xie said. “Muscadine grapes contain these inhibitory chemicals in their skins and seeds.

Plants use these compounds to protect themselves, so it is not surprising that plant leaves and skins contain these beneficial compounds,” the author noted. (IANS)

The aim of the book is to teach children that families can exist in different forms, and show them how to accept the diversity in family backgrounds.

By Siddhi Jain

Delhi-based author Pritisha Borthakur is set to release her new book, 'Puhor and Niyor's Mural of Family Stories'. The 1,404-word children's book was put together to address a new kind of societal debacle in the family system. The author says the aim is to teach children that families can exist in different forms, and show them how to accept the diversity in family backgrounds.

The author who named the book after her twin sons -- Puhor and Niyor -- is a parent who has seen and heard the tales of ridicule and discrimination suffered by many in India and beyond. She says the book is an artistic illustration for kids that details how different families can live and coexist. Whether it's children with two dads or two moms, children with a single dad or single mom, and even multiracial family units, Borthakur's book teaches love, understanding, and compassion towards unconventional families.

Beyond race, gender, color, and ethnicity which have formed the bases for discrimination since the beginning of time, this book aims to bring to light a largely ignored issue. For so long, single parents have been treated like a taboo without any attempt to understand their situations; no one really cares how or why one's marriage ended but just wants to treat single parents as villains simply for choosing happiness and loving their children.

Homosexual parents, a relatively new family system, is another form that has suffered hate and discrimination for many years. Pritisha emphasizes the need to understand that diversity in people and family is what makes the world beautiful and colourful. 'Puhor and Niyor's Mural of Family Stories' is a firm but compassionate statement against all forms of discrimination on the bases of sexual identity, gender, race, and even differences in background

Clean and maintained hands boost confidence in daily life activities.

If you feel that clean and well-groomed hands are just an essential prerequisite for women, you might like to think twice. Men should equally pay attention to their hands because our hand houses 1,500 bacteria living on each square centimeter of its skin. You can easily assume what havoc it can create in our body because in India we have the culture of eating with our hands and spaces beneath nails can become breeding heaven for germs. Moreover, clean and maintained hands boost confidence in their daily life activities. Therefore, it's important to keep your hands clean irrespective of your gender by washing or sanitizing at regular intervals. And, to keep them groomed, you don't have to visit a salon.

Rajesh U Pandya, Managing Director, KAI India, gives easy and completely doable tips to follow at home:

* Refrain from harsh soaps: You should be mindful of the soap you are using to wash your hands. Your soap can have a moisturizing element in it like aloe vera or shea butter. Ensure that you're washing your hands with normal water as hot water can make your hand's skin dry and scaly.

Bitcoin has become an essential crypto asset in modern portfolios and investment funds.

Bitcoin has become an essential crypto asset in modern portfolios and investment funds. The confidence generated in this cryptocurrency will depend a lot on the diversification that companies make in their balance sheets in Bitcoin and the increase of institutional investors that allocate a percentage of their funds in this crypto. American fund manager Cathie Wood makes some interesting predictions, both in the rise that the Bitcoin price will experience in the next 5 years, suggesting these institutional investors allocate 5% of their funds; this will help leverage the Bitcoin market.

Bitcoin will grow by a tenfold
