Ganglioside Intake Increases Plasma Ganglioside Content in Human Participants
Bibliographic record
Abstract
BACKGROUND: Preclinical studies reveal associations between intestinal ganglioside content and inflammatory bowel disease (IBD). Since a low level of ganglioside is associated with higher production of proinflammatory signals in the intestine, it is important to determine safety and bioavailability of dietary ganglioside for application as a potential therapeutic agent. MATERIALS AND METHODS: Healthy volunteers (HVs; n = 18) completed an 8-week supplementation study to demonstrate safety and bioavailabity of ganglioside consumption. HVs were randomized to consume a milk fat fraction containing 43 mg/d ganglioside or placebo, and patients with IBD (n = 5) consumed ganglioside supplement in a small pilot study. Plasma gangliosides were characterized using reverse-phase liquid chromatography-QQQ mass spectrometry. Intestinal permeability was assessed by oral lactulose/mannitol, and quality of life was assessed by quality of life in the IBD questionnaire. RESULTS: There were no adverse events associated with dietary ganglioside intake. Ganglioside consumption increased ( P < .05) plasma content of total GD3 by 35% over 8 weeks. HVs consuming ganglioside exhibited a 19% decrease in intestinal permeability ( P = .04). Consumption of ganglioside was associated with a 39% increase ( P < .01) in emotional health and a 36% improvement ( P < .02) in systemic symptoms in patients with IBD. CONCLUSION: Impaired intestinal integrity characteristic of IBD results in increased permeability to bacterial antigens and decreased nutrient absorption. Intestinal integrity may be improved by dietary treatment with specific species of ganglioside. Ganglioside is a safe, bioavailable dietary compound that can be consumed to potentially improve quality of life in patients with IBD and treat other disorders involving altered ganglioside metabolism. This study was registered at clinicaltrials.gov as NCT02139709.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
