Science Snippet: Zooming In on Nanoparticles
Nanoparticles come in many different shapes and configurations. Credit: Adapted from Stevens, et. al., under Creative Commons License 4.0.
Nanoparticles may sound like gadgets from a science fiction movie, but they exist in real life. They’re particles of any material that are less than 100 nanometers (one-billionth of a meter) in all dimensions. Nanoparticles appear in nature, and humans have, mostly unknowingly, used them since ancient times. For example, hair dyeing in ancient Egypt involved lead sulfite nanoparticles, and artisans in the Middle Ages added gold and silver nanoparticles to stained-glass windows. Over...

Mari Ruddy and Extreme Healing
Today, I have the pleasure of sharing an incredibly inspiring conversation with one of my heroes, Mari Ruddy. If you are not familiar with Mari, buckle up – her story is one of profound resilience, strength, and healing. Like me, Mari lives with type 1 diabetes. She was diagnosed in 1981, and in addition to dealing with diabetes, Mari has also courageously overcome several other life challenges.
Mari discovered her love for distance cycling at the age of 39. TeamWILD, one of the organizations she created, played a crucial role in my journey, and it...

5 Simple Habits and Routines to Keep You Away from Depression and Stress
One of the major problems facing today’s generation is depression. Excessive workload, changing lifestyle, loneliness, and financial pressure all lead to stress which results in depression. You feel unhappy, non-productive and withdrawn when you are depressed.
Many experts believe that establishing routines filled with healthy habits is a great way to move more efficiently through your day while expending less mental energy and even willpower in the process. Following simple routines like exercising, eating the right food, taking energy supplements, meditating, and getting sufficient sleep can help to manage str...

The Most Overhyped Technologies in Healthcare
The hype about technological development in healthcare should not blind us in terms of the probabilities and possibilities of today’s healthcare and the future of medicine. To remain objective and conscious but still optimistic, let’s look at the most overhyped technologies and keep in mind the realistic development opportunities in healing.
You know the saying: the pessimist says the glass is half empty, the optimist says it is half full, and, well, the cynic asks who drank the other half? I’m truly an optimist – especially when it comes to the future of medicine and healthcare, but we need to ask the uncom...

Fight Aging! Newsletter, December 4th 2023
This study produced a great deal of data that continues to be mined for insights into human aging and effects of calorie restriction in a long-lived species such as our own, to contrast with the sizable effects on health and longevity in short-lived species such as mice.
In particular, and the topic for today, cellular senescence and its role in degenerative aging has garnered far greater interest in the research community in the years since the CALERIE study took place. Thus in today's open access paper, scientists examine CALERIE study data to find evidence for calorie restriction to reduce the burden of cellular ...

The Effects of Diet on Life Expectancy
It is somewhat interesting to see a careful analysis of diet and life expectancy, using the sizable UK Biobank population, that does not contain any of the words "calorie", "weight", or "obesity". The effects of calorie intake on health over the long-term are sizable, even if we focus only on mechanisms associated with the gain of weight. Visceral fat is metabolically active, generates an increased burden of senescent cells, and contributes to the chronic inflammation of aging via a range of different mechanisms.
Thus one would assume that buried underneath this set of data on what it is that people eat is a more re...

In this study, we attempted to further explain the role, exact mechanism and target of ICA in treating AD from the ferroptosis perspective. We found that ICA could improve the neurobehavioral, memory, and motor abilities of AD mice. It could lower the ferroptosis level and enhance the resistance to oxidative stress. After inhibition of MDM2, ICA could no longer improve the cognitive ability of AD mice, nor could it further inhibit ferroptosis. Network pharmacological analysis revealed that MDM2 might be the target of ICA action.

Biological Age Acceleration Correlates with Increased Risk of Dementia and Stroke
There are now many ways to determine biological age, the most prevalent of which are epigenetic clocks and combinations of normal blood biomarkers such as the phenotypic age clock. In all cases, the idea is to identify specific measurable changes that correlate with age, and then develop an algorithm that combines the measures to produce an age as the output. Whether a given clock actually reflects all of the processes of aging, and what exactly is being measured under the hood, are questions that have yet to be satisfactorily answered. It has been noted that in all of the established biological age measures, people with a...

How confident are clinicians to deliver pain self-management?
Over the past few weeks I’ve been talking about pain self management from many perspectives. It’s an important topic because most people living with pain will be self managing most of the time. Being able to confidently self manage leads to less disability, distress and lives that look like life, not some endless healthcare regime.
A paper by Penlington et al., (2023) explored confidence beliefs of clinicians working in the UK in primary or community settings prior to a training programme that was then delivered to them. The sample included in the survey is therefore a subset of those who might be expected t...

Questions grow about the validity and usefulness of direct-to-consumer blood tests for Alzheimer ’s Disease
For the first time, people worried about their risk of Alzheimer’s disease can go online, order a blood test, and receive results in the privacy of their homes.
This might seem appealing on the surface, but the development has Alzheimer’s researchers and clinicians up in arms.
The Quest Diagnostics blood test, AD-Detect, measures elevated levels of amyloid-beta proteins, a signature characteristic of Alzheimer’s. Introduced in late July, the test is targeted primarily at people 50 and older who suspect their memory and thinking might be impaired and people with a family history of Alzheimer’s or genetic risks for t...

Fruit and sugar: Debunking the myths
On many occasions, patients have asked me whether it’s OK to eat fruit. They’re worried about whether they should be eating foods high in sugar. Is fruit in that category? No, it is not. Does anyone really believe that fruit is what’s causing the paired epidemics of diabetes and obesity? This scourge is not being

The Mindful Body argues against mindlessly accepting age-related decline in cognition and health as inevitable
In 1979, Harvard researcher Ellen Langer invited elderly men to spend a week at a retreat designed to remind them of their younger days, surrounded by the art, music, food, games, décor, and more from the late 1950s. Afterward, the men were tested and found to have made significant gains in hearing, memory, dexterity, posture, and general well-being. It was as if being in a place signaling their younger days made them physiologically “younger.”
Maybe you, too, have had an experience where your mind seemed to affect your health. It turns out there’s a reason for that, according to Langer, author of the new book The M...
