Mitochondrial Dysfunction, Oxidative Stress and Diabetic Cardiovascular Disorders
Bibliographic record
Abstract
The prevalence of diabetes has been rapidly increasing in world-wide countries. The dominant cause of mortality in diabetic patients is cardiovascular complications. Mechanism for the susceptibility of diabetic patients to cardiovascular disorders remains unclear. Elevated oxidative stress was detected in diabetic patients or in animal models. Mitochondria are one of major sources of reactive oxygen species (ROS) in cells. Mitochondrial dysfunction and DNA mutations have been detected in diabetic patients. Diabetes-associated metabolic disorders, including hyperglycemia, hypertriglyceridemia, hypercholesterolemia, hypoalphalipoproteinemia, and increased levels of advanced glycation end products, glycated and oxidized lipoproteins, are associated with oxidative stress. Glycated or oxidized low density lipoproteins (LDL) impair the activities of mitochondrial respiratory chain complex enzymes in vascular endothelial cells (EC). Dysfunction in mitochondrial respiration may increase the formation of ROS in mitochondria. NADPH oxidase (NOX) generates ROS in cytosol. Increased NOX activity was detected in diabetic patients. Glycated and oxidized LDL increase the expression of NOX and ROS production in EC. Diabetes-associated metabolic disorders may lead to mitochondrial dysfunction, NOX activation and excess ROS production, which results in oxidative stress and promotes cardiovascular disorders in diabetic patients. Statins, metformin and anthocyanidins may help to attenuate oxidative stress in vasculature induced by diabetes-associated metabolic disorders.

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; both teacher heads agree on what is shown here.
