  • Scientists discovered 36 new genes
  • These are the genes implicated in cardiac diseases
  • These genes play a casual but important role in the diseases of heart

Researchers have identified 36 new genes that plays a causal role in cardiac hypertrophy — abnormal thickening of the heart muscle — which can lead to heart failure.

“This is an exciting direction for personalised medicine, and also for identifying genes and therapeutic targets for complex diseases that involve many genes,” said co-author of the study Alain Karma, professor at the Northeastern University. According to the Centres for Disease Control and Prevention, one in four deaths in the US each year are due to heart disease.

“The framework described in the paper can also be used to predict whether individuals suffering from a particular disease will respond to a given drug treatment,” said lead author Marc Santolini, a postdoctoral research associate at Centre for Complex Network Research.

For the study, published in the journal npj Systems Biology, the researchers took an entirely different approach — using the Hybrid Mouse Diversity Panel, a collection of 100 genetically different strains of mice that can be used to analyse the genetic and environmental factors underlying complex traits.

Within each strain, the mice are inbred, making them all identical twins on a genetic level. Researchers took two mice from the same strain and gave one of them a stressor drug that induces heart failure. They then compared the stressed mouse’s gene expression with its non-stressed twin.

Since the mice have the same genome, they were able to pinpoint individual genes that changed expression as a direct result of the heart stressor.

Among the identified 36 such genes, many of these genes were previously unknown to be implicated in heart failure, the researcher said. They mentioned that one of them is known as a transcription factor, meaning it controls the expression of many other genes.

They confirmed the gene’s role by using molecular biology techniques to silence it and observe the resulting changes of expression.

They found the transcription factor gene was directly connected to a whole network of proteins known to play a role in cardiac hypertrophy. IANS

In all the wedding excitement, it's easy to overlook the impact a wedding has on the environment.

By Prerana Agarwal Saxena

In all the wedding excitement, it's easy to overlook the impact a wedding has on the environment. While everyone is making their big fat Indian wedding dreams come true, they are also adding their carbon footprint and undue energy consumption. Modern couples are now looking for ways to have a wedding with a sustainably conscious mindset. It's become about incorporating less waste, locally sourced and seasonal food, natural materials over the use of plastic. Mindful wedding planning and decor includes the use of recycled paper and goods along with eco-friendly venue needs. Check out this quick guide to achieve a sustainably conscious wedding without compromising on luxury:

Choose locally sourced material to uplift artisans
Sustainable can be luxurious too, incorporate some native flavour into the decor and theme. With the use of locally sourced materials and local artisans coming into play, the wedding instantly becomes sustainable. Include the work of local vendors ensure minimal packaging requirements, thus saving on unnecessary plastic and lamination. It also decreases the need for transporting elements from other cities and hence lowers the carbon footprint. For instance, at one of our weddings, we made use of sand art for a setup in Jodhpur. This helped promote local work while also being environmentally friendly with zero wastage of other materials. In another instance from Rajasthan, the traditional glass-blown technique was used to build decor items while giving a cultural touch to the destination wedding.

The vaccination was administered from 7 a.m. till 7 p.m. and the compiled data was made available late at night.

The Tamil Nadu health department has administered 16,43,879 lakh doses of vaccine in the second mega vaccination camp organised by it. The state public health department in a statement on Sunday said that this has taken the total vaccination to one crore since the beginning of September till date. The vaccination was administered from 7 a.m. till 7 p.m. and the compiled data was made available late at night.

The health department officials also said that as the state has almost exhausted its quota of vaccines, there would not be any vaccines on Monday. Regular vaccination will resume after the vaccine supplies arrive from New Delhi, officials said. The state health department had expected to vaccinate 15 lakh people on Sunday in 18,824 centres spread across primary health centres, anganwadis, noon meal centres, government hospitals, schools and some auditoriums.

Festivals are just around the corner and while you brainstorm about OOTDs (outfit of the day), don't forget the right makeup. Hanisha Kapoor, COO, ArchiesBeauty.com shares makeup trends experimented by these Bollywood divas throughout 2021 for inspiration. While some stuck to the classics, others mixed it up... take a look:

The Classic Red Lip
We don't see a future where classic red lips go out of fashion. The right way to achieve this celebrity look is to focus on accentuating your lips and keeping the rest of the face minimal. Give your lips a good scrub to plump them, moisturize and follow it up with a red lip liner to define the shape of your lips. Now go on with the perfect shade of red and finish your look with a slick of eyeliner, minimal concealer, and foundation.
