The objective of this research was to explore how HYQTD drug-containing serum (HYQTD-DS) could potentially protect mitochondrial energy production in endothelial cells (ECs) from injury caused by hydrogen peroxide (H2O2)-induced oxidative damage in AS through SIRT1/PGC-1α/ Nrf2 pathway.</p><p><strong>Methods: </strong>After preparation of containing serum, the cells were divided into various categories, such as control group, H2O2 group (an oxidative damage model), HYQTD group, Selisistat (EX527, a SIRT1 inhibitor) combined with H2O2 group, and EX527 combined with HYQTD group. The evaluation of oxidative stress involved measuring reactive oxygen species (ROS) and malondialdehyde (MDA) generation, as well as Superoxide Dismutase (SOD) activity. Mitochondrial function and ultrastructure were measured by Transmission electron microscopy (TEM), mitochondrial membrane potential (MMP), rate of oxygen consumption (OCR), respiratory chain complex activities, and ATP production.

Accelerating brain cell degeneration, worsening cognitive decline, and increasing susceptibility to AD can be attributed to pathogenic mechanisms linked to diabetes, such as impaired insulin signaling in the brain, neuroinflammation, oxidative stress, mitochondrial dysfunction, and vascular impairment. These factors can also lead to the accumulation of β-amyloid and tau protein phosphorylation. New research suggests that certain drugs used to manage diabetes have different levels of effectiveness in treating or preventing Alzheimer's disease. Exercise has numerous advantages, including the reduction of neuroinflammation, alleviation of oxidative stress and mitochondrial dysfunction, improvement of endothelial and cerebrovascular function, stimulation of neurogenesis, and prevention of pathological changes associated with diabetes-related Alzheimer's disease through various internal mechanisms.

The LD50 of MPE-SeNPs was determined, and doses of 1/50 and 1/20 of the LD50 were administered to HgCl₂-exposed mice to evaluate lung protective effects. Biochemical analyses measured plasma lipid profiles and lung antioxidant status, while gene expression of TGF-β1, P38, and NF-kβ in lung tissue was analyzed.
