Cardoguard, an Ayurvedic antihypertensive formulation, prevents cardiac remodeling in spontaneously hypertensive rats by inhibition of ERK and PKCε signaling pathways
Bibliographic record
Abstract
Ayurveda is an Indian system of medicine. Despite clinical efficacy, lack of scientific validation has limited the effective use of Ayurvedic drugs. Cardoguard is an Ayurvedic antihypertensive drug formulated by Nagarjuna Herbal Concentrates Ltd., Kerala, India. Left ventricular hypertrophy (LVH) is a modifiable risk factor, and regression of LVH reduces the propensity for adverse cardiovascular events. This study was taken up with the objective of evaluating the efficacy of Cardoguard in the prevention of cardiac remodeling. Cardoguard was administered orally to 2-month-old spontaneously hypertensive rats for 4 months at a dose of 5 mg·day(-1). The dose corresponds to the therapeutic dose calculated on the basis of body surface area. Lower hypertrophy index, decrease in cardiomyocyte area, and reduction of interstitial fibrosis in treated spontaneously hypertensive rats indicate amelioration of cardiac hypertrophy by Cardoguard. Cardiac output increased in response to treatment. Immunostaining for the phosphorylated components of major signaling pathways associated with hypertrophy suggests that prevention of LVH by Cardoguard is possibly mediated through inhibition of extracellular signal-regulated kinases and protein kinase C-ε signaling pathways. Reduced expression of 3-nitrotyrosine in response to the treatment suggests that prevention of cardiac remodeling by Cardoguard is mediated by reduction of oxidative stress.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
