Two different diets able to induce dietary hyperammonaemia (a methionine-choline-deficient (MCD) diet and a methionine-deficient diet enriched with ammonium acetate (MAD + 20% ammonium acetate)) were tested in a rat model. The diets were shown to have different modes of action, inducing significant hyperammonaemia (HA) and growth retardation in the rats, with different metabolic consequences. The MCD diet resulted in the development of endogenous HA, with a decrease in bilirubin levels and an increase in hepatic fat content.

Shellfish species, such as Mercenaria campechiensis, have high resilience to K. brevis exposure causing high accumulation and retention of brevetoxins within their tissues.

MSH3, a DNA mismatch repair protein, modifies HD onset and progression by driving this somatic CAG repeat expansion process. is relatively tolerant of loss-of-function variation in humans, making it a potential therapeutic target.

Seven-week-old dual-purpose female quails at the onset of laying were assigned to diets containing 0% (control), 0.5%, 1%, or 1.
