“As we'll learn from Judy, there's more than one so-called phenotype exhibited by senescent cells and they arrive at these different cellular phenotypes as a consequence of different types of cellular stress or dysfunction. Judy is a professor of biogerentology at the Buck Institute for Research on Aging and a co-editor in chief of the AGING Journal.”

“The researchers measured aspects of the participants' cardiovascular health, including flow-mediated dilation (how flexible a blood vessel is), microvascular perfusion rates (how quickly and efficiently tiny blood vessels fill), blood glucose levels, and triglycerides.”

“FTA: > Using a songbird as a model, scientists have described a brain pathway that replaces cells that have been lost naturally and not because of injury. If scientists can further tap into the process, it might lead to ways to encourage replacement of cells in human brains that have lost neurons naturally because of aging or Alzheimer's disease.”

“At the end of the six-month period, the parents and children completed personality assessments and provided reports about the children's behavior, especially externalizing behavior (such as fighting or lying) and internalizing behavior, such as depression, anxiety, and withdrawal.”

“Vitamin D is a steroid hormone that participates in many aspects of human health, including regulation of the renin-angiotensin-aldosterone system, an endocrine system that plays key roles in blood pressure control.”

“While senescence plays a vital role in human development and wound healing, the accumulation of senescent cells is associated with diseases of aging such as Alzheimer's disease, Parkinson's disease, cardiovascular disease, type 2 diabetes, and glaucoma.”

The authors of the study drew on data from the Progetto Veneto Anziani (https://pubmed.ncbi.nlm.nih.gov/18283228/), a long-term cohort study of more than 3,000 older adults (65 years and older) living in northern Italy.

“Participants reported their dietary fiber intake and wore accelerometers to track their physical activity. The DEXA scans revealed that women who consumed more fiber had considerably greater muscle mass than those who ate less.”

“All participants completed a battery of physical performance tests at baseline, six months, and one year later, including the six-minute walk test, the 30-second chair stand, and the timed up-and-go.”

“A mid-day nap at least 3x per week in children ages 10-12 was associated with a 7.6% increase in academic performance, elevated mood, improved self-control, and fewer behavioral problems.”
