A Common Probiotic Could Boost Brain Health in Older Adults

Posted by in categories: biotech/medical, health, neuroscience

It’s said the way to one’s heart is through the stomach, but it looks like the way to a healthy brain is by dropping a deuce regularly. According to new research presented at the Alzheimer’s Association International Conference in Amsterdam this week, chronic constipation appears to be linked to worsening cognitive abilities, likely due to an imbalance of gut bacteria causing inflammation.

While the study has yet to be peer-reviewed, it emphasizes a link between cognition and the microbiome — microorganisms like bacteria, viruses, and fungi living rent-free in and on our bodies — that hasn’t gone unnoticed. There’s still a whole lot we don’t know about the microbiome, but what we do know suggests these microscopic houseguests can be manipulated to improve our own health.

To offset cognitive decline, it could be as simple as a daily probiotic, says Mashael Aljumaah, a doctoral student at the University of North Carolina at Chapel Hill (UNC) and North Carolina State University. In findings presented Monday at the American Society for Nutrition in Boston, Aljumaah and her colleagues at UNC and Kent State University in Ohio found that for older adults, a daily probiotic containing gut-friendly Lactobacillus rhamnosus helped improve mild cognitive impairment by resetting the imbalance in gut bacteria.

Transplant of fresh brain cells replaces diseased and aged ones

Posted by in categories: biotech/medical, neuroscience

Researchers have transplanted cells capable of forming specialized brain support cells into mice brains and found that they not only competed with and replaced unhealthy cells but aged ones, too. The findings open the door to developing an effective treatment for a range of conditions like multiple sclerosis, ALS, Alzheimer’s disease, autism and schizophrenia.

‘Glial cells’ is an umbrella term for the cells that are a support system to nerve cells (neurons). Progenitor cells are descendants of stem cells that can differentiate into specific cell types, and, in the case of glial cells, human glial progenitor cells (hGPCs) differentiate into subtypes, including astrocytes and oligodendrocytes, specialized for particular functions.

Astrocytes comprise most of our central nervous system cells, providing support and protection for neurons, transporting nutrients and removing waste. Oligodendrocytes lay down and maintain the lipid-rich, insulating wrapping called myelin around some axons, the part of the neuron that connects with another neuron and allows the transmission of nerve impulses.

Distinguished Lecture Series | Why life began with RNA | Trivedi School of Biosciences

Posted by in categories: biotech/medical, chemistry

This video, which is a part of the Distinguished Lecture Series by Trivedi School of Biosciences, Ashoka University, Prof. Jack W. Szostak discusses why life began with RNA. Why was Ribose sugar chosen in the primordial soup, and not several other alternative sugars that may have been available? He shows this using elegant experiments that include chemistry and structural biology.

Distinguished Speaker: Prof. Jack W. Szostak.
2009 Nobel Laureate in Physiology or Medicine.
