Researchers in Hyderabad claim to have developed a promising technology for creating in the lab “implantable bioengineered humanized” livers for the management of acute liver failure (ALF), one of the most devastating fatal conditions.
The technology, successfully demonstrated in animal experiments, “has enormous potential for clinical translation” in managing ALF patients desperately waiting for liver transplants, it is claimed.
The study by researchers at the Centre for Liver Research of the Deccan College of Medical Sciences (DCMS) has been reported in the Elsevier journal “Material Science & Engineering-C”.
Currently liver transplantation has been the only treatment option available for ALF. But its wider applicability has been limited by high cost, non-availability of quality donor organs and the need to use immunosuppressive drugs throughout life.
It is here that the animal study by researchers at DCMS’s Centre for Liver Research raises hopes of an alternative approach although clinical trials in humans are yet to validate this.
In their animal experiment, the DCMS researchers chemically-induced ALF in mice and then used their technology to make the affected livers functional again.
The experimental procedure involved harvesting the complete livers of the ALF mice with intact blood vessels (hepatic artery and portal vein) followed by decellularisation — a process that removes the intracellular components from the liver tissue while preserving only the liver “scaffold” and its native 3-dimensional architecture.
In the next step, the scaffold is “repopulated” with human hepatic progenitor cells that differentiate into “hepatocytes,” which constitute 80 per cent of the human liver. Finally, the laboratory-made, bioengineered humanised livers — in which mouse liver tissue has been replaced by human cells — are transplanted back into rats.
According to the DCMS researchers, the strategy for rapid and efficient decellularisation and repopulation adopted by them “is superior” to earlier approaches reported by other workers.
“Over the next years, we aim to optimise the technique in a larger scale to generate ready-to-use bioengineered humanised livers for supplying on demand and validate its safety and efficacy in human,” said report co-author Aleem Ahmed Khan. “Immediate human trials are desirable to benefit healthcare without further delay.”
Chaturvedula Tripura, a cell biologist at the CSIR-Centre for Cellular and Molecular Biology in Hyderabad said the DCMS study has demonstrated “an efficient and promising technology” for addressing ALF through bio-engineering and transplantation of humanised livers.
“The study is excellent scientific work,” added Sanjay Nagral, director of Surgical Gastroenterology at Jaslok Hospital & Research Centre in Mumbai.
“The promise that the bio-engineered liver tissue, especially from other species holds for future human use is indeed interesting,” he said.
However, further studies are warranted to explore the suitability of this strategy in larger animal models and future human trials, the researchers say. (IANS)
Every child who grew up in the 90s and the early 00s has certainly grown up around Tom and Jerry, the adorable, infamous cat-chases-mouse cartoon. The idea of naughtiness and playing mischief had the standards that this particular series set for children and defined how much wreckage was funny enough.
The show's creators, William Hanna and Joseph Barbera initially named their characters Jasper and Jinx. They did not plan for the fame that Tom and Jerry brought them when they released a movie by the name of "Puss Gets the Boot". This movie featured a certain cat and mouse who were a notorious pair, named Jasper and Jinx. When the movie became a hit, the names of the characters were changed and the show shot to fame.
Tom and Jerry became a go-to cartoon for children in the early 00s, and it was one of those shows with a firm foundation, that had already been in the running for decades. The original template had been planned nearly 80 years ago, and the makers did not change it. The music that was played in the many episodes, made a breakthrough in its own way. It is the most easily recognizable melody with utterly nostalgic associations.

A set of supporting characters were defined for the show, to occasionally take the focus off the original pair. There was a large, black woman named Mammy Two Shoes and a bulldog who took Jerry's side. Mammy Two Shoes was discontinued because her character portrayed racist tendencies. A tall white woman replaced her, who was kinder and loved mice. Either of the women's faces was never revealed.
Today, Tom and Jerry is still a household name in homes where children love cartoons. There are a host of other shows besides this that aim to replicate the same aspects of the cartoon but do not come close at all. Despite the immense amount of violence in the show, it is a beloved pastime of parents and children alike.

One of India's leading private museums, the Museum of Art & Photography (MAP) Bengaluru, has released new primary research conducted by the ReReeti Foundation, on audience behaviour in India's cultural sector. While more than half of the respondents thought the arts and culture are essential, they rarely manage to make time for it. The majority (60.6 per cent), mostly young people under 30, felt Indian museums could present more engaging content, and most perceived culture as anthropological/ sociological. Of the diverse categories included, music emerged as the most popular cultural activity.
The report is based on a survey of 500 people, which included school and college students, professionals across sectors, homemakers and senior citizens. The first initiative of its kind in the cultural space, the report shares valuable insights into the behaviour and expectations of Indian audiences engaging with a broad range of cultural activities. As part of MAP's mission to foster meaningful connections between communities and the cultural sector globally, which includes its innovative digital programme Museums Without Borders, the report shares a wealth of insights that can help museums across the country understand their audiences better. As much as 60.6 per cent said Indian museums are not experimental enough, and can do more to create engaging content that is also relevant to surrounding communities.As much as 60.6 per cent said Indian museums are not experimental enough, and can do more to create engaging content that is also relevant to surrounding communities.

Speaking on the recent report, Kamini Sawhney, Director, Museum of Art & Photography (MAP), said, "MAP is focused on changing the notion of a museum in India, by enabling more relevant and inclusive programming, both online and in our space in Bengaluru. The audience research commissioned by MAP, and conducted by the ReReeti Foundation, provides valuable, and actionable insights which we hope will help museums across the country better understand their consumer base, improve decision making and deepen social impact." As much as 62.3 per cent college students and 47.6 per cent professionals/homemakers perceive culture as anthropological and sociological. Music was the most popular cultural event likely to be attended, followed by heritage tours and plays/comedy shows for Indian audiences.
Over 70 per cent of college students visit museums with family and friends; working professionals, homemakers and senior citizens also predominantly visit with groups/ spouses (indicating a need to focus on increased group programming/facilitation). As much as 68 per cent of people were optimistic about going outdoors for activities and events in 2021. As much as 60.6 per cent said Indian museums are not experimental enough, and can do more to create engaging content that is also relevant to surrounding communities.(IANS/MBI)

What is the best way to save Goa from deforestation?
Drinking feni, may well be the answer, says the secretary of the Goa Cashew Feni Distillers and Bottlers Association Hansel Vaz, who on Thursday said, that sipping the state's unique alcoholic drink and making it popular would directly aid the greening of Goa's hills and other barren landscapes.
"To get more cashews, we need to plant more trees. I always say, by drinking feni you will save Goa, because we will be planting more cashew trees and we will have greener hills. The beauty of cashew is you do not need fertile land. You can grow it on a hill which can provide no nutrition. We will be able to grow more trees, if we can sell feni properly," Vaz said. Vaz's comments come at a time when the hillsides of the coastal state have witnessed significant deforestation for real estate development and for infrastructure projects. Feni is manufactured by fermenting and double distilling juice from the cashew apple.

Addressing a press conference in Panaji, Vaz also said that the promotion of feni was also in sync with the Prime Minister's vision for India to go "vocal for local". "There is no conglomerate, multinational company owning the drink. So every time we sell feni, it is a direct cash injection into Goa. If you sell a feni cocktail in Calangute (a popular beach village), it makes a direct impact in Valpoi and Bicholim, because this money is going down there," the Association official said at a press conference in Panaji.
The Association held the media briefing to announce a road map ahead for the feni industry, especially vis a vis streamlining aspects related to production, standardisation and marketing of the brew to make it popular in other Indian states and abroad.
The efforts to streamline the state "heritage drink" comes a month after the Goa government notified a formal policy, 'Goa Feni Policy 2021', which covers 26 different varieties of feni distilled in the state. "There were many barriers related to feni, which the policy has now addressed," treasurer of the Association Tukaram Haldankar said. One such hurdle was the previous government classification, which described feni as "country liquor", which would deter tourists from purchasing the drink. The reclassification of feni as a state "heritage drink" has lent dignity to the brew which has been manufactured locally in Goa since the 16th century.

But there is more the government can do, along with the state's traditional distillers and manufacturers to promote feni, Haldankar said. "We request the government to allow the sale of feni in duty free stores in airports and cruise liner terminals. The government should also support us through the department of Tourism, so that feni can be promoted in its programmes. iIf you go to Scotland, they promote Scotch. Goa should promote its feni to Goa," Haldankar said, adding that traditional distillers should also be given subsidies and other measures should be taken to standardise feni, which he said, "would require further subsidies and financial assistance from the government".
"It should be a standard product like scotch, champagne," Haldankar said. "Like Mexico's tequila, Russian vodka and Japan's sake, we need to export our feni across the country and the world and the local distillers should also benefit economically," president of the Association Gurudutt Bhakta also said.
