Egg white protein hydrolysate reduces blood pressure, improves vascular relaxation and modifies aortic angiotensin II receptors expression in spontaneously hypertensive rats
Bibliographic record
Abstract
Angiotensin converting enzyme (ACE) inhibitory peptides from egg have demonstrated reduction of blood pressure (BP) in vivo . In this study we evaluated the effects of egg white hydrolysate (EWH) prepared by thermolysin and pepsin in spontaneously hypertensive rats (SHRs). Fourteen to sixteen week old SHRs were implanted with telemetry devices. After recovery, the rats were divided randomly into three groups: untreated, EWH low dose (250 mg/kg BW), and EWH high dose (1000 mg/kg BW) for 12 days. BP showed a significant reduction in the EWH high dose group compared to untreated controls. BP reduction was associated with enhanced ex vivo vasodilation reduced oxidative/nitrosative stress, reduced angiotensin converting enzyme and angiotensin II type 1 receptor expression , while enhanced angiotensin II type 2 receptor expression. Circulating level of angiotensin II was unaffected. Thus, EWH exerted anti-hypertensive effects in SHRs through multiple mechanisms of vascular relaxation and RAS modulation.

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.
