Inflammation linked with Alzheimer’s, reduced cognition and brain fog

Posted by in categories: biotech/medical, neuroscience

Several newly published studies are reporting evidence affirming a growing hypothesis that links inflammation with cognitive deficits. As well as associating inflammation with the cognitive deficits seen in conditions such as bipolar disorder and Alzheimer’s, some research is even suggesting low-grade systemic inflammation in healthy subjects can result in mental sluggishness.

For some time patients suffering from chronic inflammatory conditions such as rheumatoid arthritis or inflammatory bowel disease have reported mild cognitive deficits in association with their disease. Despite a number of correlational studies finding connections between inflammation and cognitive performance, homing in on any clear causal links has been a little tricky for scientists.

“Scientists have long suspected a link between inflammation and cognition, but it is very difficult to be clear about the cause and effect,” explains Ali Mazaheri, from the University of Birmingham. “For example, people living with a medical condition or being very overweight might complain of cognitive impairment, but it’s hard to tell if that’s due to the inflammation associated with these conditions or if there are other reasons.”

Rejuvenation: If I could turn back time … — Longevity.Technology

Posted by in categories: biotech/medical, chemistry, existential risks, life extension, neuroscience

Last week, the BBC reported on the plight of axolotls in Mexico City, which are under threat of extinction. [1] The risk to these creatures is made doubly concerning when you consider their incredible ability to regenerate and apparent immunity to cancer, which is of great interest to scientists and companies working in the Longevity sector. One such company is Bioquark, a Philadelphia-based life sciences company that is working on the development of combinatorial biologics for the rejuvenation and repair of human organs and tissues. Among its clinical plans, it lists the development of therapeutic products for cancer reversion, organ repair and regeneration, and even brain death resuscitation. Nothing major then!

Bioquark has developed a novel combinatorial biologic called BQ-A, which mimics the regulatory biochemistry of the living human egg (oocyte) immediately following fertilization. While ooplasm-based reprogramming has been studied in experiments such as in-vitro fertilization and cloning, Bioquark claims it is the first company to apply it to somatic tissue in mammals.

We spoke with Bioquark’s CEO, Ira Pastor, a 30-year veteran of the pharmaceutical industry, to find out more about the company and where it’s headed.

The Ethical Implications of Mind-Machine Meld | Future You | NPR

Posted by in categories: computing, Elon Musk, neuroscience

The fast-moving development of brain-machine interfaces got a boost when Elon Musk announced the work for Neuralink, his new company devoted to implantable devices to enhance cognition and better marry our brains with super-computing. His competitor, fellow tech entrepreneur Bryan Johnson of Kernel, weighs in on why he thinks advancing cognition can solve all the other problems in the world. But tech ethicist Tristan Harris says not so fast — we haven’t properly accounted for what existing tech has already done to us. Think things through with this brainy episode of Future You with Elise Hu.

Longevity And Health

Posted by in categories: biotech/medical, education, life extension, neuroscience

Education and bravery are the key to our survival. In this article we dig into the correlation between health and longevity.


With so many supplement salesman and scientists talking about longevity it can get confusing as to exactly what that might mean. Of course we all want to live as long as we can but most would agree to it only if they were able to be healthy and active. After all how would life be worth it if you were confined to a bed or wheelchair in constant pain?

As we improve health we also extend life. One drawback to extending life is that we face health problems we might have avoided by simply not being alive. However as we extend life we will also extend health and find ways to cure all diseases. For most of humanity throughout the ages Cancer or Alzheimer’s was rarely a cause for concern. Cancer and Alzheimer’s was not as prevalent because most people did not live long enough to be stricken with them. Many humans died from infections, starvation, and injury and thus the expected life span was much lower than today. Every time a new advancement is made in healthcare we improve the odds of living longer. Hospitals, handwashing, and vaccines all improved a human beings chance of survival and also their chance of contracting a new or otherwise unusual disease.

“Surprising” new insights into link between gut microbiome and aging

Posted by in categories: biotech/medical, life extension, neuroscience

A new study is suggesting a metabolite produced by gut microbes could increase neuron production in the brain, improve intestinal function, and ultimately slow the aging process. Across several compelling mouse experiments the research found the negative effects of aging could be counteracted by enhanced microbial production of a molecule called butyrate.

Investigating the effect of the gut microbiome on aging, the new research first performed gut microbiome transplants between old and young mice. Using fecal transplants, young germ-free mice were colonized with the gut microbiota of older mice. The results were somewhat unexpected as the younger mice colonized with the older microbiomes displayed increased neurogenesis, a process whereby new neurons are produced in the brain.

“We’ve found that microbes collected from an old mouse have the capacity to support neural growth in a younger mouse,” explains Sven Pettersson, lead on the research team from Nanyang Technological University in Singapore. “This is a surprising and very interesting observation…”

Life-long epigenetic programming of cortical architecture

Posted by in categories: biotech/medical, evolution, food, genetics, life extension, neuroscience

The evolution of human diets led to preferences toward polyunsaturated fatty acid (PUFA) content with ‘Western’ diets enriched in ω-6 PUFAs. Mounting evidence points to ω-6 PUFA excess limiting metabolic and cognitive processes that define longevity in humans. When chosen during pregnancy, ω-6 PUFA-enriched ‘Western’ diets can reprogram maternal bodily metabolism with maternal nutrient supply precipitating the body-wide imprinting of molecular and cellular adaptations at the level of long-range intercellular signaling networks in the unborn fetus. Even though unfavorable neurological outcomes are amongst the most common complications of intrauterine ω-6 PUFA excess, cellular underpinnings of life-long modifications to brain architecture remain unknown. Here, we show that nutritional ω-6 PUFA-derived endocannabinoids desensitize CB1 cannabinoid receptors, thus inducing epigenetic repression of transcriptional regulatory networks controlling neuronal differentiation. We found that cortical neurons lose their positional identity and axonal selectivity when mouse fetuses are exposed to excess ω-6 PUFAs in utero. Conversion of ω-6 PUFAs into endocannabinoids disrupted the temporal precision of signaling at neuronal CB1 cannabinoid receptors, chiefly deregulating Stat3-dependent transcriptional cascades otherwise required to execute neuronal differentiation programs. Global proteomics identified the immunoglobulin family of cell adhesion molecules (IgCAMs) as direct substrates, with DNA methylation and chromatin accessibility profiling uncovering epigenetic reprogramming at 1400 sites in neurons after prolonged cannabinoid exposure. We found anxiety and depression-like behavioral traits to manifest in adult offspring, which is consistent with genetic models of reduced IgCAM expression, to suggest causality for cortical wiring defects. Overall, our data uncover a regulatory mechanism whose disruption by maternal food choices could limit an offspring’s brain function for life.

New Body Structure Might Explain How Cancer Spreads

Posted by in categories: biotech/medical, neuroscience

It seems incredible that scientists have discovered a new human organ. I mean, they cut people open right and left (living and dead). How could they miss anything?

Well, they did. A new organ has been identified. Actually, two. Plus a new “structure” that is not quite an organ.

First, the “structure”: In 2017, an elaborate system of drainage vessels was seen in the brain for the first time. Until then their existence was suspected, but not certain.
