A novel gene therapy uses an implanted LED device to reset a racing heart immediately and automatically, paving the way for pain-free treatment for patients with heart rhythm disorder.

The therapy detects fast arrhythmias in the atrium of a rat’s heart and sends a signal to a LED device placed near the heart.


“The flash of light from this LED then causes the heart to generate an electric current itself to halt the arrhythmia,” said lead investigator Daniel Pijnappels at Leiden University in the Netherlands.

“This is made possible by using gene therapy to introduce specific light-sensitive proteins into the heart. This restores the heart’s normal rhythm immediately and automatically,” he added.

According to the researchers, this could represent a great improvement on the current way of stopping atrial fibrillation.

Atrial fibrillation is the most common heart rhythm disorder in clinical practice. The current treatment, known as cardioversion, is based on administering an electric shock to the heart, which has to be done in the hospital under general anaesthesia because of pain.

For many patients, this is the only treatment to immediately stop atrial fibrillation because drugs or an operation are ineffective.

“The bioelectronic defibrillator can stop atrial fibrillation without an electrical shock. In this way, the heart can be reset in a fully automated manner and at any time,” Pijnappels said, in the paper reported in the journal Science Translational Medicine.

“We anticipate that this treatment for atrial fibrillation could improve both the patient’s quality of life and their prognosis,” he added.

However, considerable research is still needed before a treatment can be arrived at that is suitable for human patients, the researchers noted. (IANS)

The Centre will launch a pilot project on the use of indigenously manufactured drones for delivering medicines in the undulating landscape of Jammu and surrounding areas from Saturday

The Centre will launch a pilot project on the use of indigenously manufactured drones for delivering medicines in the undulating landscape of Jammu and surrounding areas from Saturday with a focus on vaccines delivery initially. "This is going to be a pilot project for the area. The drone is developed and manufactured entirely by our scientists," Union Minister for Science & Technology, Dr Jitendra Singh told mediapersons. Singh said he himself will be launching the project at Jammu.

The drone is developed by the scientists at Bengaluru's National Aerospace Laboratories (NAL), a constituent of Council of Scientific and Industrial Research (CSIR), an autonomous Society that is headed by the Prime Minister. For now, the delivery would be limited to Covid vaccines and once successful, it would be expanded to be used for regular delivery of medicines in the remote, hilly areas.

According to him Amitabh Bachchan is a great actor in the industry.

Bollywood actor Abhishek Bachchan shares how he feels when people compare him with his father Amitabh Bachchan on the singing reality show 'Sa Re Ga Ma Pa'. He also requests contestant Rajshree Bag to sing a track 'Bahon Mein Chale Aao' featuring his mother Jaya Bachchan.

Abhishek said after looking at the performance of Rajshree, who is often compared with Lata Mangeshkar on the show, that she reminds him of being compared with his father. "Rajshree, whenever I have got the chance to watch the show, I've seen people compare you to Lata didi. It actually reminded me about how people compare me with my father and ask me how I feel about it."

According to him Amitabh Bachchan is a great actor in the industry and this is what he says to everyone making these comparisons. "My answer to them is that there's no greater actor in this film industry than Amitabh Bachchan and if I'm being compared to him, I am sure I must have done something good."

"Similarly, your voice has a different kind of magic like Lata ji and that's why people are comparing your voice with her. I feel you should always take this as a compliment," he concluded. 'Sa Re Ga Ma Pa' airs on Saturday and Sunday on Zee TV. (IANS/ MBI)

Winters in India have always beckoned for that hot, steaming bowl of tomato and pepper rasam or the mellow, millet based Raab. Certain dishes like sarson ka saag, undhiyu, nimona pulao are winter specialites in the country. Seasonal food has always been an Indian speciality -- we switch our choice in fruits, vegetables, sometimes even grains with the onset of different season. The preference of using specific ingredients during certain climates is visible in our sweets as well. It's common to find local and traditional delicacies made of jaggery, instead of sugar during the winters. Case in point -- the Nolen Gur Rasgulla, a speciality made in Odisha and West Bengal between November to February.
