Effects of long‐term intake of Antarctic krill oils on artery blood pressure in spontaneously hypertensive rats
Bibliographic record
Abstract
Abstract BACKGROUND In recent years, there has been a noticeable increase in research on krill oil (KO) for its health benefits. However, the action of KO in lowering blood pressure (BP) has not been studied yet. Therefore the aim of this study was to assess the ability of long‐term KO supplementation to lower systolic BP (SBP) in spontaneously hypertensive rats (SHRs) and Sprague Dawley (SD) rats. RESULTS Compared with the blank control (BC) SHRs administered edible soybean oil, the high‐dose (500 mg kg−1 body weight (BW)) KO‐supplemented SHRs in the 2nd, 3rd, 4th and 5th weeks following oral administration, the mid‐dose (100 mg kg−1 BW) KO‐supplemented SHRs in the 4th and 5th weeks following oral administration and the low‐dose (20 mg kg−1 BW) KO‐supplemented SHRs in the 5th week following oral administration showed significantly lower SBP (P < 0.05). However, supplementation of KO had no significant effect on the SBP of healthy SD rats. Meanwhile, 5 weeks of KO administration significantly increased the serum levels of nitric oxide (NO) and total NO synthase of SHRs (P < 0.05). CONCLUSION KO has an antihypertensive effect in SHRs that is associated with an NO‐related mechanism. © 2016 Society of Chemical Industry

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.
