CSS changes occurring over this 3-day weekend

None of the dark mode plug-ins that I have experimentally activated for use with this website created sought after presentation dynamics. As a result, visitors to this site should expect to endure color discontinuities Sunday night while I carefully make changes within the 2400 CSS lines of the theme file. Monday – Friday nightly updates will not be interrupted.

Red Onions & Tryptophan

The tryptophan dosing ingested with the whole red onion diet quite potently stimulates deep sleep & a strong serotonin feel good response . While the screen glare has resolved, I haven’t, as yet, latched firmly on to the targeted neurogenic direction of expected plasticity gains.

Versed readers will recognize the links between my dietary experiment & continuing deep dive into the importance to mental health of brain mitochondria vitality & the benefits of controlled tapping of its grown reserves {I haven’t had a cup of coffee in over 5 years…& black tea is a new menu item]

Routines, habits, & writing methods

I am still identifying references & updating notations being cited in the blog I am writing on Polyphenols, Mitochondria, Glial Cells, & Neurodegeneration. If you scan through its draft, my media rich approach to writing such articles will be plain: topic , parameter descriptions & correlations, & avenues of research. Its pace of completion is obviously slowed by ongoing, as currently demonstrated, adjustments to my schedule intended to channel available energy into feature organization & production.

Polyphenols, Mitochondria, Glial Cells & Neurodegenrative Pathway Studies (draft)

I spent a great deal of time this past week investigating the organic chemistry dynamics of the ACS study Mechanistic Insights into Polyphenols’ Aggregation Inhibition of α-Synuclein and Related Peptides. This study only examined the impact of resveratrol & gallic acid on the aggregation of α-synuclein & its results showed that rather than disrupting α-synuclein aggregation the polyphenols merely became weakening elements of a broadened sheet. Importantly, the narrow scope of this research excluded consideration of whether the toxicity to glial cells of this disease causing protein was lessened & their dutiful activities excited by the studied polyphenols.

Here I am interested in the vitality of glial mitochondria & their susceptiblity to problematic exposure mitophagy which requires having evidence of how the citric acid cycle for its energy production (ATP reservoir on/off switch) is affected by disease conditons.

Another week of previews

I am slowly adding 3rd party attributive images to the nedia library here. Also, I don’t expect to post book reviews until July at the earliest. At present, I’m reading Nick Lane’s Transformer. This, of course, has led me to pick up Power, Sex, & Suicide & Vital Questions so that I will have a more comprehensive understanding of his point of view & greater insight into the perspective shared by Joseph LeDoux in the The Deep History of Ourselves.

Week in Review

My approach for this website remains mostly unchanged. I will continue providing links to noteworthy open access brain science & humanities research supplemented by lectures, podcasts, & well-used french & spanish language audio & articles; all of which now wil be stacked on a newest first to best of basis during the week rather than statically archived together on a daily basis. On weekends, in addition, I will variously blog book reviews, article discussions, & lecture highlights.
