Mechanisms of remodelling of small arteries, antihypertensive therapy and the immune system in hypertension
Bibliographic record
Abstract
This review summarizes my lecture for the 2015 Distinguished Scientist Award from the Canadian Society of Clinical Investigation, and is based mainly on studies in my laboratory on the mechanisms of remodelling of small arteries in experimental animal and human hypertension and on treatments that lower blood pressure and improve structure and function of resistance vessels. Small resistance arteries undergo either inward eutrophic or hypertrophic remodelling, which raises blood pressure and impairs tissue perfusion. These vascular changes are corrected by some antihypertensive drugs, which may lead to improved outcomes. Vasoconstriction, growth, oxidative stress and inflammation are some of the mechanisms, within the vascular wall, that can be beneficially affected by antihypertensive agents. These antihypertensive-sensitive mechanisms are reviewed in this review, together with the inflammatory and immune mechanisms that may participate in hypertension and associated cardiovascular injury. Molecular studies, based on this research, will hopefully identify novel diagnostic and therapeutic targets, which will improve our ability to prevent and treat hypertension and cardiovascular disease.

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.
