A new mathematical framework on molecular interactions will make it easier and more efficient for scientists to develop new medicines and other therapies for diseases such as cancer, HIV and autoimmune diseases, say reseachers.

The mathematical framework simulates the effects of the key parameters that control interactions between molecules that have multiple binding sites, as is the case for many medicines, the researchers said in a study, published in the journal Proceedings of the National Academy of Sciences (PNAS). The researchers have planned to use this computational model to develop a web-based app that other researchers can use to speed the development of new therapies for diseases.


“The big advance with this study is that usually researchers use a trial-and-error experimental method in the lab for studying these kinds of molecular interactions, but here we developed a mathematical model where we know the parameters so we can make accurate predictions using a computer,” said Indian-origin researcher and study senior author Casim Sarkar from University of Minnesota in the US.

“This computational model will make research much more efficient and could accelerate the creation of new therapies for many kinds of diseases,” Sarkar added.

For the findings, the research team studied three main parameters of molecular interactions–binding strength of each site, rigidity of the linkages between the sites, and the size of the linkage arrays.

They looked at how these three parameters can be ‘dialled up’ or ‘dialled down’ to control how molecule chains with two or three binding sites interact with one another. The team then confirmed their model predictions in lab experiments. “At a fundamental level, many diseases can be traced to a molecule not binding correctly,” said study lead author Wesley Errington.

“By understanding how we can manipulate these ‘dials’ that control molecular behaviour, we have developed a new programming language that can be used to predict how molecules will bind,” Errington added.

The need for a mathematical framework to decode this programming language is highlighted by the researchers’ finding that, even when the interacting molecule chains have just three binding sites each, there are a total of 78 unique binding configurations, most of which cannot be experimentally observed.

By dialling the parameters in this new mathematical model, researchers can quickly understand how these different binding configurations are affected, and tune them for a wide range of biological and medical applications. “We think we’ve hit on rules that are fundamental to all molecules, such as proteins, DNA, and medicines, and can be scaled up for more complex interactions,” said Errington.

“It’s really a molecular signature that we can use to study and to engineer molecular systems. The sky is the limit with this approach,” Errington added. (IANS)

Char Dham Yatra resumed on Friday with more than 16,000 devotees resuming the pilgrimage from the Rishikesh camp.

As weather cleared up in Uttarakhand, Char Dham Yatra restored on Friday with more than 16,000 devotees resuming the pilgrimage from the Rishikesh camp.

According to sources, road leading to Badrinath has been repaired and helicopter service has also resumed.

Meanwhile, Uttarakhand Chief Minister Pushkar Singh Dhami visited Dungi village and met families of people who were missing after the landslip incident, and consoled them.

Dhami assured them of all possible assistance. Two people from the village are still reported to be missing.

Pilgrims were seen leaving from Rishikesh Char Dham Bus terminal and Haridwar bus station for the pilgrimage since morning.

As per the state government, various departments -- Devasthanam Board, police are assisting the pilgrims.

Police Chowki Yatra Bus Terminal, Rishikesh, was announcing passenger-information via loudspeaker.

Free RT-PCR tests of pilgrims were being conducted at Rishikesh bus terminal.

Uttarakhand Char Dham Devasthanam Management Board's media in-charge Dr Harish Gaur said pilgrimage was on in Kedarnath, Gangotri and Yamunotri, while for Kedarnath, helicopter service was also available.

Though the weather was cold in all dhams, thankfully there was no rain, he added.

Portals of the temple in Badrinath will close on November 20, Gangotri on November 5, while that of Kedarnath and Yamunotri on November 6.

Uttarakhand floods, triggered by a major downpour from October 17 to 19, have claimed 65 lives so far, 3,500 people have been rescued while 16,000 evacuated to safety.

Seventeen teams of National Disaster Response Force (NDRF), seven teams of State Disaster Response Force (SDRF), 15 companies of Provincial Armed Constabulary (PAC) and 5,000 police personnel have been engaged in rescue and relief operations.

The state has already been provided with Rs 250 crore Disaster Fund which is being used for relief works.

To prevent spread of the diseases, the Central and state governments have decided to send medical teams to the affected areas.

Snapped power lines will be restored at the earliest, the government assured.

The state government said that as soon as alert for heavy rainfall was issued, the Incident Response System was activated at state and district levels, and pilgrims were halted at safer places. (IANS/JB)

Naga leaders are adamant in their main demands for a separate Constitution and flag.

The Centre has continued the Naga peace talks with the Isak-Muivah faction of National Socialist Council of Nagalim (NSCN-IM) leaders, but negotiations face roadblocks as the Naga leaders are adamant in their main demands for a separate Constitution and flag.

The sources aware of these developments said that the Centre was hopeful that a successful solution of the six decades-long peace talks would arrive at a logical conclusion, but in the recent statements, Naga leaders have accused the Centre of offering post-solution options.

Sources quoting the stand of Naga leaders said that NSCN's stand was loud and clear that it would not follow the forbidden route to the Naga solution that was linked to foregoing the Naga national flag and Constitution, which is the face of the Naga political struggle and identity.

The Naga leaders have also said that the Centre has been using divisive policy and flattery in the name of finding the Naga political solution when the matters heated up.

When the Centre resumed the peace process in September this year and sent the former special director of the Intelligence Bureau (IB) A.K. Mishra as the Ministry of Home Affairs' emissary to the rebel outfit's chief negotiator and general secretary T. Muivah, he assured him (Muivah) that the peace talks would be initiated under the original framework signed in 2015, a source in the Naga rebel group said.

"Here we are talking about the Naga national flag and Yehzabo (Constitution), the two issues that are holding up the Naga solution under the ongoing Indo-Naga political talks in Delhi.

"The chequered history of the Indo-Naga political issue is clear enough before us, with accords and agreements that were never meant to be implemented in letter and spirit", an important office-bearer of the rebel outfit said while criticizing the governments' stand.

Accusing the Centre, he further accused the Centre of persuading the Naga people again to accept whatever is being offered to hurry up the Naga talks.

On the invitation of the Centre, the senior leaders of the NSCN-IM including T. Muivah arrived in the national capital on October 6 this year to hold another round of talks with the Centre.

Both, the Centre and the Naga leaders had indicated their keenness on resolving this long pending issue by the end of this year in an amicable manner.

Assam Chief Minister Himanta Biswa Sharma, who is also chairman of North East Democratic Alliance (NEDA), and Nagaland Chief Minister Neiphiu Rio had been actively involved in the resumption of the peace talks and taking it forward to a logical conclusion.

Soon after the transfer of Nagaland Governor R.N. Ravi, who was appointed as the Centre's interlocutor for the Naga peace talks on August 29, 2014, to Tamil Nadu, the peace talks resumed on September 20 in Kohima when the Centre representative met the Naga leaders and invited them to visit Delhi for further rounds of peace talks.

The NSCN-IM and the other outfits entered into a ceasefire agreement with the Government of India in 1997 and over 80 rounds of negotiations with the Centre have been held in the past in successive governments. (IANS/JB)

India-England test series will now be played next year from July 1 at Edgbaston Stadium

The series decider for the Test series between England and India will now be played at Edgbaston from July 1 next year, said the England and Wales Cricket Board (ECB) on Friday. India is currently leading the series 2-1 before the fifth Test at Old Trafford was cancelled hours before the start due to concerns over COVID-19 outbreak in the tourists' camp.

"The fifth match of the LV= Insurance Test Series between England Men and India Men has been rescheduled and will now take place in July 2022. The match, which was due to take place last month at Emirates Old Trafford, was called off when India were unable to field a team due to fears of a further increase in the number of Covid-19 cases inside the camp," said an ECB statement.

"With India leading the series 2-1, the concluding fifth match will now take place from July 1, 2022, at Edgbaston, following an agreement between the England and Wales Cricket Board (ECB) and the Board of Control for Cricket in India (BCCI)," added the statement.

ECB also said that due to the rescheduled Test, the white-ball series between England and India will now start six days later than originally planned. The T20I series will begin on July 7 at Ageas Bowl with Edgbaston and Trent Bridge hosting the second and third matches respectively on July 9 and 10. It will be followed by the ODI series starting on July 12 at The Oval followed by Lord's and Old Trafford hosting the second and third ODI on July 14 and 17 respectively.

"Ticket holders do not have to take any action as all tickets will remain valid for the equivalent rearranged matchday at their host venue. Host venues will communicate the new fixture details to ticket purchasers and the options available to them, including the timeframe for requesting a refund if they are not able to attend the new match day," further said the statement.

"We are very pleased that we have reached an agreement with BCCI to creating a fitting end to what has been a brilliant series so far. I'm very grateful to all the venues involved for the cooperation they've shown in allowing us to reschedule this match. I'd also like to thank Cricket South Africa for their support and understanding to allow these changes to be possible," said Tom Harrison, the CEO of the ECB.

"We would like to apologise again to fans for the disruption and disappointment of September events. We know it was a day that so many had planned long in advance. We recognise that accommodating this extra match means a tighter schedule for the white ball series. We will continue to manage our players' welfare and workloads through next year while we also continue to seek the optimum schedule for fans, players and our partners across the game."

"I am delighted that the England-India Test series will now have its rightful conclusion. The four Test matches were riveting, and we needed a fitting finale. The BCCI recognizes and respects the traditional form of the game and is also mindful of its role and obligations towards fellow Board Members. In the last two months, both BCCI and the ECB have been engaged in discussions and our efforts were aimed at finding a suitable window. I thank the ECB for their understanding and patience in finding an amicable solution," said BCCI Secretary Jay Shah. (IANS/JB)
