The Role of Exercise-Based Cardiac Rehabilitation After Myocardial Infarction on Cholesterol Transfer to HDL.

High-density lipoprotein (HDL) is associated with decreased incidence of cardiovascular events, and its functionality also influences prognosis. Exercise is an important tool to improve prognosis in the post-infarction (MI) population, but the role of exercise on HDL functionality is poorly understood. Sixty-two patients with acute MI were randomized in a supervised exercise program for 12-14 weeks (exercise group-EG) or a control group (CG).

Analysis of Plasticizer Contamination Throughout Olive Oil Production.

This study monitored the contamination of 32 plasticizers in olive oil throughout the production and storage process. Samples were collected at different stages of production from three olive oil production lines in distinct regions of Portugal and analyzed for 23 phthalates and 9 phthalates substitutes to identify contamination sources. The developed analytical method employed liquid-liquid extraction with hexane/methanol (1:4, /), followed by centrifugation, extract removal, and freezing as a clean-up step.
