“Your skin is a crucial barrier to the outside world – the first line of defense against environmental exposures, and the primary means by which the body retains fluids necessary for survival. Consequently, maintaining a healthy skin barrier is important for your overall health. In this Aliquot, Dr. Patrick describes some things you can do to protect your skin.”

“Advanced glycation end-products, or AGEs for short, are created when the sugars, amino acids, and fats in food encounter heat. AGEs also form in the body during normal glucose metabolism. However, if high levels of AGEs accumulate in the tissues and blood, they can become pathogenic.”

“Vascular dysfunction, the loss of normal endothelial tone and permeability of blood vessels, is a common feature of most forms of dementia, including Alzheimer's disease. People who carry the APOE4 gene are at greater risk for vascular dysfunction and Alzheimer's disease.”

“Preventing dementia requires a lifelong and multipronged approach that involves keeping inflammation (and its aging effects) at bay and making healthy lifestyle choices, such as exercising and consuming omega-3 fatty acids.”

Hormesis is a compensatory defense response to a stressor that conditions the body against future stressors. Heat exposure – from sauna use, hot tubs, or eve...

“Early biomarkers of vascular dysfunction, such as soluble platelet-derived growth factor receptor-beta (sPDGFR-β), can help identify individuals at risk for developing Alzheimer's disease. These biomarkers are being validated on high-throughput platforms for large-scale testing.”

“However, the ability to translate data from non-human animals to humans can be limited and the use of laboratory animals can raise ethical concerns. In this clip, Dr. George Church describes the pros and cons of animal research and how we could move beyond its use with advanced technologies.”

“The mechanisms that drive the effects of sauna bathing include activation of heat shock proteins and pro- and anti-inflammatory cytokines; decreased blood pressure and arterial stiffness; and multiple improvements in cardiovascular function.”

“Approximately 25 percent of people living in the United States carry a genetic variant of this lipoprotein called APOE4, which is associated with higher circulating levels of LDL cholesterol and an increased risk for Alzheimer's disease.”

“Dr. Attia and Dr. Patrick agree that avoiding low vitamin D status is the clearest goal. Large prospective analyses consistently find higher risk at low 25-hydroxyvitamin D concentrations, while the evidence becomes less certain once people reach sufficiency.”
