Scientists Create the most Accurate Epigenetic Clock Yet

Published

on

If you are curious about how you age and whether you are naturally prone to develop certain diseases, then you probably want to pay more attention to the Epigenetic clock.

Scientists have developed the epigenetic clock which reveals information on the connection between a rapidly ageing brain and Dementia, including Alzheimer’s disease.

The epigenetic clock is to ageing what the circadian clock is to sleeping and waking cycles.

The scientists who are based at the University of Exeter analyzed brain tissue samples taken from human brains to come up with the epigenetic clock. The epigenetic clock is more accurate than others created using other tissue samples or blood samples.

According to lead researcher Professor Jonathan Mill, more research into Epigenetic clocks could unlock more understanding of the aging process.

“Our new clock will help us explore accelerated aging in the human brain. As we’re using brain samples, this isn’t a model that can be used in living people to tell how fast they’ll age. However, we can apply it to donated brain tissue to help us learn more about the factors involved in brain diseases such as dementia” says Mill.

Researchers studied the epigenetic markers responsible for DNA methylation within the human cortex. These epigenetic markers signal genes to switch on or go off.

The result is the most accurate epigenetic clock so far – one that predicts the biological age of the brain more accurately than ever before, according to Gemma Shireby of the University of Exeter.

The scientists eventually found 347 DNA methylation sites and it through these sites that they were able to make their accurate predictions within the cortex.

Their model held up when it was tested against 1,221 brain tissue samples collected by the Brains for Dementia Research cohort. The BRD cohort gets is funding from the Alzheimer’s Research UK and the Alzheimer’s Society on 1,175 blood samples.

The methylation data was instrumental in the creation of biomarkers for aging. These biomarkers for ageing are epigenetic clocks.

These clocks help scientists to understand how biological age and chronological change differ in terms of managing diseases like neurodegeneration as well as dementia among other brain types.

Researchers are excited because the new epigenetic body clock beats all its predecessors in its predictions of the biological age of the human brain.

They conclude that the reason why this new epigenetic clock is so accurate is that they used brain tissue samples relevant to the study of brain health. Because they were working with brain tissue, they were able to come up with a more accurately calibrated epigenetic clock to enable them to investigate dementia.

The Dawn of AI-Enhanced Rehabilitation: How AI-Powered Trousers are Revolutionizing Stroke Recovery

Published

on

By

In the quaint town of Penarth, Vale of Glamorgan, a remarkable story of resilience and technological innovation is unfolding. Julie Lloyd, a 65-year-old stroke survivor, is relearning to walk, aided by a groundbreaking piece of technology: trousers powered by artificial intelligence (AI). This pioneering trial in the UK marks a significant leap in medical technology, offering new hope to stroke victims worldwide.

The Breakthrough in Stroke Rehabilitation

Julie’s journey is not just a personal triumph but a beacon of hope for millions affected by strokes. According to the World Health Organization, strokes are the second leading cause of death globally, and the leading cause of acquired disability among adults. The road to recovery is often long and arduous, with traditional rehabilitation methods providing varying degrees of success.

The AI-powered trousers represent a paradigm shift in rehabilitation technology. As Julie puts it, “I really feel this is the breakthrough for stroke victims that has been much and long awaited for.” This sentiment echoes the sentiments of many in the medical community who have long sought more effective ways to aid stroke recovery.

How the Technology Works

The AI trousers are a marvel of modern engineering and medical science. They function by using a series of sensors and motors that work in tandem with the wearer’s movements. This technology is not just about physical support; it’s about enhancing the body’s natural ability to relearn movements. The AI component analyses the wearer’s gait, providing real-time adjustments to improve walking patterns, much like a physical therapist would.

This approach is grounded in the concept of neuroplasticity, the brain’s ability to reorganize itself by forming new neural connections. By assisting in the correct movement patterns, the trousers help the brain to ‘relearn’ walking, potentially speeding up the recovery process.

The Impact on Stroke Rehabilitation

The implications of this technology are vast. For stroke survivors, the journey to recovery can be filled with frustration and despair. Traditional rehabilitation methods can be slow and, at times, ineffective. The AI trousers offer a more dynamic and responsive form of therapy that could revolutionize how we approach stroke rehabilitation.

In a study conducted by the American Stroke Association, it was found that early and individualized rehabilitation can significantly improve outcomes for stroke survivors. The AI trousers align perfectly with this philosophy, offering a tailored rehabilitation experience that adapts to the individual’s needs.

Challenges and Future Prospects

Despite the promise, the road ahead for AI in medical rehabilitation is not without challenges. Cost and accessibility are significant concerns. Cutting-edge technology often comes with a high price tag, potentially putting it out of reach for many who could benefit from it.

Moreover, there’s the challenge of integrating such technology into existing healthcare systems. As noted by experts in healthcare technology, the adoption of new medical technologies often faces hurdles in terms of regulatory approval, practitioner training, and patient acceptance.

However, the future looks bright. As AI and robotics continue to advance, we can expect these technologies to become more affordable and widespread. The potential for AI to aid in various aspects of healthcare, from diagnosis to treatment and rehabilitation, is enormous.

Conclusion

Julie Lloyd’s story is just the beginning. As we stand on the cusp of a new era in medical technology, the possibilities are endless. The AI-powered trousers are more than just a piece of technology; they are a symbol of hope and a testament to human ingenuity. For stroke survivors around the world, this could be the dawn of a new day in rehabilitation, one where technology and human resilience come together to create new possibilities.

AI-Powered Medical Database Aims to Revolutionize Doctor-Patient Interactions

Published

Artificial Intelligence (AI) is making inroads into various sectors, and healthcare is no exception. According to a recent NPR article, Dr. Michael Mansour of Massachusetts General Hospital is among the early adopters testing an AI-enhanced version of UpToDate, a widely-used medical database. This experimental version employs generative AI to provide doctors with more targeted information, aiming to streamline the diagnostic process.

Wolters Kluwer Health, the company behind UpToDate, is working on making the database more conversational, allowing doctors to maintain the context of their queries. While the technology is still in beta and has some kinks to work out, the potential is enormous. AI could not only assist in making accurate diagnoses but also free up doctors’ time, allowing them to focus more on patient care. As Dr. Marc Succi of Mass General Brigham aptly puts it, “AI won’t replace doctors, but doctors who use AI will replace doctors who do not.”

A New way around Drug Resistant Tuberculosis

Published

on

By

Researchers at Purdue University have created a powerful compound that specifically tackles Tuberculosis, a leading killer worldwide.

The scientists came up with a series of inhibitors that destroy TB by targeting a protein necessary for the survival of the TB molecule.

Tuberculosis destabilizes the immunity of patients with the help of Protein Tyrosine Phosphates B (mPTPB). Their findings were published in the Journal of Medicinal Chemistry.

“The death toll from TB is particularly high because of drug-resistant strains,” said Zhong-Yin Zhang, distinguished professor and head of Purdue’s Department of Medicinal Chemistry and Molecular Pharmacology and director of Purdue Institute for Drug Discovery. “These inhibitors are part of a promising new approach to developing TB therapeutic agents with novel targets and mechanisms of action to help save more lives.”

Right now, doctors rely on antibiotic preparations to treat Tuberculosis. The problem is that many patients don’t complete their dose of antibiotics and this non-adherence leads to the development of drug resistant tuberculosis.

“We developed a platform to target mPTPB for novel anti-TB agents that builds on technologies we pioneered to modulate abnormal protein tyrosine phosphatase activity for the treatment of diseases such as cancer, diabetes and autoimmune disorders,” Zhang elaborated.

According to Zhang, the inhibitors’ have unique properties that make them incredibly useful. They have a lighter molecular weight and superior metabolic stability. They give scientists an excellent opportunity to create better treatments for Tuberculosis.

The visionary scientists are already working to patent the exciting new technology. The hunt is on for partners who will work with Purdue to further the development of the new technology. This is together with the Purdue Research Foundation Office of Technology Commercialization.
