A Randomized, Controlled Clinical Trial Demonstrates Improved Cognitive Function in Senior Dogs Supplemented with a Senolytic and NAD+ Precursor Combination

Aging reversed in dogs face_with_colon_three

Age-related decline in mobility and cognition are associated with cellular senescence and NAD+ depletion in dogs and people. A combination of a novel NAD+ precursor and senolytic, LY-D6/2 was examined in this randomized controlled trial. Seventy dogs were enrolled and allocated into placebo, low or full dose groups. Primary outcomes were change in cognitive impairment measured with the owner-reported Canine Cognitive Dysfunction Rating (CCDR) scale and change in activity measured with physical activity monitors. Fifty-nine dogs completed evaluations at the three-month primary endpoint, and 51 reached the six-month secondary endpoint. There was a significant difference in CCDR score across treatment groups from baseline to the primary endpoint (p=0.02) with the largest decrease in the full dose group. There were no significant differences between groups in changes in measured activity. However, the proportion of dogs that improved in frailty and owner-reported activity levels and happiness was higher in the full dose group than other groups. Adverse events occurred equally across groups. All groups showed improvement in cognition, frailty, and activity suggesting placebo effect and benefits of trial participation. We conclude that LY-D6/2 significantly improves owner-assessed cognitive function and may have broader effects on frailty, activity and happiness as reported by owners.

Insomnia: Insomnia is a common sleep disorder

Insomnia is a common sleep disorder. If you have it, you may have trouble falling asleep, staying asleep, or both. As a result, you may get too little sleep or have poor-quality sleep. You may not feel refreshed when you wake up.

What are the types of insomnia?

Insomnia can be acute (short-term) or chronic (ongoing). Acute insomnia is common. Common causes include stress at work, family pressures, or a traumatic event. It usually lasts for days or weeks.

‘Can control computer mouse with thoughts’: Says Elon Musk on Neuralink’s first human patient as he successfully recovers

Elon Musk disclosed that a human patient implanted with a brain chip from the company has fully recovered and demonstrated the ability to control a computer mouse using their thoughts.

Alzheimer’s Might Not Actually Be a Brain Disease, Expert Reveals

The pursuit of a cure for Alzheimer’s disease is becoming an increasingly competitive and contentious quest with recent years witnessing several important controversies.

In July 2022, Science magazine reported that a key 2006 research paper, published in the prestigious journal Nature, which identified a subtype of brain protein called beta-amyloid as the cause of Alzheimer’s, may have been based on fabricated data.

One year earlier, in June 2021, the US Food and Drug Administration had approved aducanumab, an antibody-targeting beta-amyloid, as a treatment for Alzheimer’s, even though the data supporting its use were incomplete and contradictory.

Korean researchers develop insect brain-inspired motion detector

The new semiconductor is expected to have some important applications in things like transportation and security systems in both industry and the public.

Korean researchers have developed a new “intelligent sensor” semiconductor that works similarly to the optic nerves of insects.

A team of researchers from Korea have developed an insect brain-inspired semiconductor that can be used as a fast, low power motion detector.

Early vocabulary size is genetically linked to ADHD, literacy, and cognition

Early language development is an important predictor of children’s later language, reading and learning skills. Moreover, language learning difficulties are related to neurodevelopmental conditions such as attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD).

Children typically start to utter their first words between 10 and 15 months of age. At around two years of age, they may produce between 100–600 words, and understand many more. Each child embarks on its own developmental path of language learning, resulting in large individual differences. “Some variation in can be related to variation in the stored in our cells,” says senior researcher Beate St Pourcain, lead scientist on the study.

Prof Nadeem Sarwar — Corporate VP, Co-Founder & Head, Transformational Prevention Unit, Novo Nordisk

Professor Nadeem Sarwar is Corporate Vice President, Co-Founder and Head, Transformational Prevention Unit, Novo Nordisk (https://www.novonordisk.com/partnerin…), Co-Chair UK Dementia Mission (a UK Government Ministerial appointment) and Honorary Professor, University of Edinburgh Medical School.

Professor Sarwar joined Novo Nordisk in June 2023 as Corporate Vice President, Co-Founder and Head of Novo Nordisk’s new Transformational Prevention Unit (TPU) whose mission is to increase obesity-free life years, so people live healthier and longer lives. To achieve this, the TPU is establishing an integrated ecosystem that will deliver science-first, empowering, and scalable commercial solutions that predict and pre-empt obesity and its consequences through innovative partnerships, with solutions intending to push the boundaries of what is possible with drugs, genomics, microbiome, digital health, and behavioral science.

Professor Sarwar’s expertise stems from scientific and business models at the intersection of genomics, data sciences and digital technologies for therapeutic and health innovation and he utilizes this expertise to steer the strategy and implementation of the predictive and pre-emptive obesity solutions being developed by the TPU, spanning both R\&D and commercial strategy.

Professor Sarwar joins Novo Nordisk with extensive executive experience in academia (Cambridge, Edinburgh), pharma (Pfizer, Eisai, Novo Nordisk), biotech (Genetics Guided Demantia Discovery — G2D2), company incubation (Eisai Innovation Biolabs), and government (UK Dementia Mission). He has successfully built and led organizations across the UK, US, Japan, and Denmark; and contributed to delivery of therapeutics into clinical trials for cardiometabolic diseases, oncology, SLE, COVID-19 and neurodegeneration.

Professor Sarwar’s research has been published in leading medical journals (eg, NEJM, Lancet, JAMA), presented at international meetings (eg, American Diabetes Association; World Dementia Council), and profiled by international media (eg, BBC, Forbes). He has provided expert insights for the UK Department of Health, the World Economic Forum, and the US National Academies of Sciences.

Apart from his current position at Novo Nordisk, Professor Sarwar holds the position of Honorary Professor at the University of Edinburgh Medical School. He also currently serves on the UK Medical Research Council (MRC) Neuroscience and Mental Health Board, the UK MRC Prevention Task and Finish Group, the Health Data Industry Expert Sub-Group, and the UK Life Sciences Council.

Q&A: How a potential treatment for Alzheimer’s disease could also work for type 2 diabetes

Of the 38 million Americans who have diabetes, at least 90% have type 2, according to the Centers for Disease Control and Prevention. Type 2 diabetes occurs over time and is characterized by a loss of the cells in the pancreas that make the hormone insulin, which helps the body manage sugar.

These cells make another protein, called islet amyloid polypeptide or IAPP, which has been found clumped together in many type 2 diabetes patients. The formation of IAPP clusters is comparable to how a protein in the brains of Alzheimer’s disease patients sticks together to eventually form the signature plaques associated with that disease.

Researchers at the University of Washington have demonstrated more similarities between IAPP clusters and those in Alzheimer’s. The team previously showed that a can block the formation of small, toxic Alzheimer’s protein clusters. Now, in a recently published paper in Protein Science, the researchers have used a similar peptide to block the formation of IAPP clusters.
