Impaired Neurovascular Coupling and Increased Functional Connectivity in the Frontal Cortex Predict Age-Related Cognitive Dysfunction.

Impaired cerebrovascular function contributes to the genesis of age-related cognitive decline. In this study, the hypothesis is tested that impairments in neurovascular coupling (NVC) responses and brain network function predict cognitive dysfunction in older adults. Cerebromicrovascular and working memory function of healthy young (n = 21, 33.

Effect of guarana seed powder on cholesterol absorption in vitro and in Caco-2 cells.

Cardiovascular disease risk is related to oxidative stress and hypercholesterolemia. Guarana seed powder contains flavanols that possess antioxidant properties and cholesterol-lowering effects. However, the molecular mechanism through which guarana seed powder may decrease cholesterol uptake from the intestinal lumen remains unclear.

Coffee simulated inhibition of pancreatic lipase and antioxidant activities: Effect of milk and decaffeination.

Noncommunicable diseases (NCDs) are the leading cause of mortality worldwide. Dietary intake of polyphenols may protect against the development of NCDs. Coffee is a rich source of phenolic acids in the Western diet that may prevent or treat hyperlipidemia, type 2 diabetes, chronic liver diseases, and obesity.
