Researchers at UC Berkeley report that a combination of two dietary supplements, acetyl-L-carnitine and alpha-lipoic acid, improved the health and cognitive function of old rats. The supplements were found to boost energy-producing organelles in cells, restore memory function, and reduce oxidative damage.

Research reveals a decline in general practitioners' and family physicians' involvement in non-office settings, leading to a reduction in comprehensive care. Alternative models such as group practices and networks can help meet the need for primary care, but reliance on core physicians working in multiple settings remains a concern.
