Foods rich in Vitamin C (such as dark leafy greens, broccoli, kiwifruit and oranges) can enhance treatment and enable a faster recovery for people suffering from tuberculosis (TB), if taken along with regular medication.

TB is one of the world’s deadliest diseases, with one third of the global population infected. In 2016, it affected 10.4 million people around the world and caused 1.7 million deaths.

Findings

  • Giving Vitamin C — a powerful antioxidant that reduces oxidative stress to the body and also lowers cancer risk — with TB drugs could reduce the unusually long time it takes these drugs to eradicate this pathogen.
  • The addition of Vitamin C to TB drug treatment potentiates the killing of bacterium Mycobacterium tuberculosis (MTB) and could shorten TB chemotherapy.
  • That’s important because treatment of drug susceptible TB takes six months, resulting in some treatment mismanagement, potentially leading to the emergence and spread of drug-resistant TB.

Vitamin C had no activity by itself, but in two independent experiments, the combination of Vitamin C with the first-line TB drugs, isoniazid and rifampicin, reduced the organ burdens faster than the two drugs without vitamin C, said Catherine J. Vilcheze, at the varsity.

“Vitamin C is known to be safe and our current mouse studies suggest that Vitamin C could enhance TB chemotherapy,” said lead investigator William R. Jacobs, from the Albert Einstein College of Medicine in New York.

Methodology

  • The team treated MTB-infected mice with anti-TB drugs or vitamin C alone, or the drugs and vitamin C together.
  • Experiments in infected tissue cultures demonstrated similar results, shortening the time to sterilisation of the tissue culture by seven days.

The study was published in the journal Antimicrobial Agents and Chemotherapy. (IANS)

Colorless chemicals were developed and mixed in varying ratios to dye hair.

A couple of years ago, finding a strand of grey hair meant visiting the parlor to cover it up. Women and men refused to admit their age, and refused to let it show. Be it moustache, eyebrows, or hair on the head, it was dyed a luscious black, or reddish-brown for those who wanted to go natural. Today, the trend of coloring hair has nothing to do with age. Young boys and girls sport bright colors and hairstyles, which is now a marker of how modern one can be.

This notion of modernity associated with neon streaks and an almost gothic look originates from the ancient Egyptian civilization, where it was considered fashionable to look different from the natural features one was born with. Kohl, lipstick, perfume, and makeup were the inventions of those who hoped to live even after death. Likewise, they were the first people to discover hair dye. Initially, they dyed their hair black, to cover the grey. They used compounds that were extracted from plants, but some of them were lethal. So, they took to extracting the color from fermented leeches.

One of the bookshop at Daryaganj, Chandni Chowk, Delhi.

The history of Daryaganj goes back to the era of Mughal dynasty, and so its history is as old as the old city of Shahjahanabad, now Chandni Chowk. Interestingly, this market was known as Faiz Bazaar in the Mughal era and was considered as an important commercial place.

In fact, at that time this area was very posh, and had beautiful houses on both sides of a stream from a hauz (meaning, water storage tank) flowing down the centre. Not only this, trees were lined up for shade and it looked like a marvellous garden had been turned into a market.
