IIT-BHU scientists' technology to check drug resistance of viruses
Varanasi: Scientists at Indian Institute of Technology (BHU) have developed new framework to help understand how virus evolves to evade drugs and treatments. While the technology focuses primarily on Coronavirus (SARS-CoV-2), it can also be applied to other pathogens and infectious diseases.
The study, led by assistant professor at the School of Biochemical Engineering, Aditya Kumar Padhi, was published in the Biophysical Journal. The 'integrated multi-scale computational framework' combines several advanced computer-based methods including protein design, machine learning, hybrid QM/MM, and multi-scale simulations. It helps identify mutations or changes in viral proteins leading to drug resistance.
The discovery comes at a time when Covid-19 cases are being reported. As the virus continues to mutate rapidly, the framework can help anticipate how it might resist treatment in future. While the current study focuses on resistance to sotrovimab, a monoclonal antibody used against SARS-CoV-2, the framework is applicable to other diseases too, including cancer and urinary tract infections. The team members of Laboratory for Computational Biology & Biomolecular Design (LCBD) contributed significantly to understanding resistance mechanisms against several other antiviral drugs and monoclonal antibodies against SARS-CoV-2.

Padhi said there were plans to make this framework freely available to scientists and doctors worldwide to support global fight against drug resistance. The research also aligns with India's national health initiatives, such as Integrated Disease Surveillance Programme (IDSP) and National Programme on Containment of Antimicrobial Resistance (AMR). "We developed this framework to address complex healthcare problems like antimicrobial resistance using integrated computational methods.
Its modular design makes it suitable for a wide range of biomedical and healthcare challenges," said Padhi.
IIT-BHU Director prof Amit Patra said, "Such advanced technologies reflect the scientific leadership of Indian institutions like IIT- BHU in research and innovation, particularly in tackling infectious diseases and major public health challenges. This also significantly contributes to the objectives of the key programme of the govt of India."

In the line of duty: Army leads tireless search, rescue operations after landslides in North Sikkim
NEW DELHI: After the deadly landslide in North Sikkim's Chatten on June 1, the army is carrying out non-stop rescue and relief work, battling heavy rain, rough terrain, and growing uncertainty over the fate of those still missing. Lachen village, a popular tourist spot now completely cut off, has been reconnected by foot thanks to the army. Troops have reached 113 stranded tourists, and efforts to evacuate them are in progress, though bad weather remains a major hurdle. On June 3, 33 tourists, including 2 US nationals, were safely airlifted by military helicopters, from the rain battered Chaten region in the north Sikkim. Supplies and national disaster response force (NDRF) personnel were also air-dropped as part of emergency operations. However, an early morning attempt to evacuate the remaining tourists from Lachen was aborted due to poor visibility. An Mi-17 carrying nine NDRF personnel from Pakyong Airport was forced to turn back mid-air. Meanwhile, the army is advancing its search for six people who went missing after the landslide wiped out part of a military camp. A rescuer stationed in the area confirmed that nine personnel lost their lives in the disaster. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like BCP CFD: Tu oportunidad de ingresos extra principales inversores Leer más Undo 'Very, very heavy rains have been experienced in the area from May 30 onwards,' said the army personnel, deployed at the site. 'The rains were so heavy that a huge waterfall had been created due to the landslide on the other side of the mountain. This never existed before. We carried out certain precautionary evacuations," ANI quoted the official. However, nothing was anticipated on this side of the mountain, where 50-70 personnel were residing. Unfortunately, nature got the better of our nine personnel.' He added, 'In the last three days, we have mobilised all our resources and have been able to recover three of the remains. We are constantly searching for the six personnel who remain missing.' The missing include Lieutenant Colonel Pritpal Singh Sandhu, his wife Squadron Leader Aarti Sandhu (Retd), their daughter Amayra Sandhu, Subedar Dharamveer, Naik Sunilal Muchahary, and Sepoy Sainudheen PK. Specialised search teams and engineering equipment have been deployed, but worsening weather, unstable soil, and the region's high-altitude terrain continue to hamper efforts. Authorities say rescue and relief operations will continue round-the-clock until all stranded individuals are brought to safety and the missing accounted for.

Roll back fee hike for medical courses: IMA
Ahmedabad: The Indian Medical Association (IMA) wrote a letter to chief minister on Tuesday, requesting a reversal of the recently approved fee for govt and self-financed medical courses. Tired of too many ads? go ad free now The association highlighted that the hike could prevent talented students from pursuing medical education. "The hike for govt quota and management quota is 10% to 12%, which has become an issue of concern for the parents and students," read the letter. "In the interest of the students and medical fraternity at large, we request you to immediately revoke the hike as a positive solution to the problem." Last year, the fee regulatory committee, which typically sets fees for self-financed institutions on a three-year basis, established fees for just one year due to post-Covid adjustments. The committee indicated that fees for the subsequent two years would be determined after reviewing the financial records of colleges. The committee has now formally declared an average fee increase of 12%, attributing this to inflation and financial assessments. Despite the committee's position that the increase is essential for maintaining operations at self-financed colleges, the letter signed by IMA Gujarat president Dr Mehul Shah and secretary Dr Gargi Patel contends that this considerable rise in yearly fees will create significant financial strain for students and their families.

MBBS, BDS application forms to be available from June 6
Application forms for admission to state quota seats in MBBS and BDS programmes will open up on June 6, Health Minister M. Subramanian announced on Wednesday. The Minister held a consultation with the heads of private and government medical and dental colleges. The admission process would commence early to enable scrutiny of the applications diligently. In the previous years the government had waited until the declaration of NEET and as a result there was not much time to scrutinise the applications, resulting in errors, he explained. Candidates must include their NEET registration number while filling in the applications. The final merit list will, however, be based on the results provided by the National Testing Agency. Candidates have been given the opportunity to wait till the declaration of NEET results. Such candidates must apply within five days of declaration of NEET results, the medical education has decided. Mr. Subramanian has instructed private medical and dental colleges to be transparent about the fee structure, giving a break up of the various components, such as tuition and hostel fees and any other amount that is being collected. Earlier in the day the Minister launched training programmes for health care workers. There is no reason to panic over COVID 19 infection, health minister M. Subramanian said here on Wednesday. Until Tuesday 216 persons have been diagnosed with COVID-19 infection and they are getting better. Those who have been infected are being monitored, the minister said. To remain safe people have been advised to wear masks in crowded places to avoid contracting infections. A person who has been diagnosed with COVID 19 infection and dies is tested for various other parameters as well to identify the cause of death. 'We do all the investigations including for COVID 19. The person may have died of other underlying causes and COVID 19 infection may have been an incidental finding,' health department officials said at a media briefing here on Wednesday on the sidelines of launch of training programme for health workers in chronic obstructive pulmonary disease and fatty liver disease. The field workers will raise awareness about the diseases and those who have them would be urged to get screened at primary health centres. The health department has also planned to launch 'Nalam Kakkum Stalin' in a fortnight in Chennai, the Minister announced. Under the scheme people can seek master health check-ups nearer to home. At the camps people can also get the required persons with disabilities certificates, persons can also get their cards under the Chief Minister's Comprehensive Health Insurance Scheme. Across the state 1,256 camps will be held by December-end.
