Abstract
We investigated the effects of 4% fructose plus moderately high salt (MHS) (4% NaCl) treatment on tissue aldehyde conjugates, platelet cytosolic free calcium ([Ca2+]i), renal morphology, and systolic blood pressure (SBP) in Wistar-Kyoto rats, and whether these effects were reversible (R) after withdrawal of treatment. At age 7 weeks, rats were divided into 4 groups: NS group, given normal salt (NS) diet (0.7% NaCl) for 18 weeks; NS+F(R) group, NS diet and fructose in water for 14 weeks, then 4 weeks fructose withdrawal; MHS+F group, NS diet and fructose for 6 weeks, then MHS diet and fructose for 12 weeks; and MHS+F(R) group, NS diet and fructose for 6 weeks, then MHS diet and fructose for 8 weeks, then MHS and fructose withdrawal for 4 weeks. SBP in the NS+F(R) group increased during fructose treatment, but normalized within 1 week of withdrawal. Tissue aldehyde conjugates and platelet [Ca2+]i were normal at completion. Adverse renal vascular changes did not reverse to normal and were similar to those of the salt plus fructose-treated groups. This may have implications for future development of hypertension. MHS did not cause any additional increase in SBP or associated tissue alterations when added to fructose treatment. However, the SBP and tissue changes persisted even after discontinuation of treatment. The fructose and salt combination may result in long-lasting vascular alterations leading to hypertension.

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.
