Here's an open access academic article about toxic airplane cabin air -

Burden of Proof: The Debate Surrounding Aerotoxic Syndrome [2022]
https://pmc.ncbi.nlm.nih.gov/articles/PMC9452852/

"... some manufacturers developed a safer alternative. Boeing Aircraft introduced a new air intake system for the Boeing 787 Dreamliner, which does not use bleed air to supply the cabin; instead, air intakes have been mounted along the root of the front wings, thereby reducing the risk of contamination."

Burden of Proof: The Debate Surrounding Aerotoxic Syndrome

Since the 1980s, some commercial airline pilots and flight crews in the United States, United Kingdom and Australia began to report an illness they believed was caused by exposure to contaminated cabin air. Despite a body of scientific research and ...

The senoprotein tested was Gas6; it is a vitamin K dependent protein and it's activities are dependent on carboxylation. Unfortunately the original research article * is paywalled, so no details on carboxylation ...

Effect of vitamin A supplementation on iron status in humans: A systematic review and meta-analysis - PubMed

Anemia is a worldwide public health problem that can be related to many causes, including vitamin A deficiency. The aim of this study was to assess and estimate the effect of vitamin A supplementation (VAS) on iron status biomarkers and anemia in humans. Six databases, including Cochrane, EMBASE, LI …

Interesting case report:

Early coma in intussusception: Endogenous opioid induced?
https://pubmed.ncbi.nlm.nih.gov/3562307/

Abstract
A decreased level of consciousness with little abdominal pain or gastrointestinal symptoms is an uncommon, but well described, presentation of infantile intussusception. Its etiology is unclear. We describe a 10-month-old male who presented with coma and miosis, reversible with bolus injections of naloxone on three separate occasions. No opiates were involved and an intussusception was subsequently found. We speculate that the coma and miosis were induced by an endogenous opioid which could also mask the abdominal pain, thus explaining this presentation of intussusception. If so, miosis would be a valuable clue for diagnosing such children.

I can feel a difference when I drink hibiscus tea. It tastes good, but it's really acidic and I worry about my teeth.

First sentence in this paywalled article: "Pascal Geldsetzer believes in open access, in disseminating science as quickly as it happens."

I understand good articles cost money to produce, but - it just seems a bit ironic. And I can't help but be disappointed that I can't access this article since it sounds interesting.

Biophotons: New Experimental Data and Analysis

Biophotons are an ultra-weak emission of photons in the visible energy range from living matter. In this work, we study the emission from germinating seeds using an experimental technique designed to detect light of extremely small intensity. The emission from lentil seeds and single bean was analyzed during the whole germination process in terms of the different spectral components through low pass filters and the different count distributions in the various stages of the germination process. Although the shape of the emission spectrum appears to be very similar in the two samples used in our experiment, our analysis can highlight the differences present in the two cases. In this way, it was possible to correlate the various types of emissions to the degree of development of the seed during germination.
