The decline of the immune system is of great importance in aging. Vulnerability to infection, a decreased surveillance of senescent cells and cancerous cells, and growing chronic inflammation all take their toll. A sizable fraction of this problem stems from the diminished supply of new T cells of the adaptive immune system. T cells begin life as thymocytes in...
UNIVERSITY OF MINNESOTA MEDICAL SCHOOL MINNEAPOLIS/ST.PAUL (04/20/2021) — University of Minnesota Medical School researchers have offered new ways to think about the immune system thanks to a recent study published in Nature. Their research, which indicates organ tissues become increasingly immune throughout life, may begin to alter fundamental ideas regarding the rules of vaccination and the immune system’s function...
FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO Aging entails a loss of muscle mass and strength, which in some cases impairs mobility, hinders walking or performance of day-to-day tasks, and exposes the elderly to the risk of falls and hospitalizations. In clinical practice, handgrip measurement is the most widely used method to...
by Kanazawa University T1WI with muscle and vein ROI set on the T1WI of the cross section at the center of the marker. Muscle area was measured for GAS and SOL. The vein area was measured for the PV and the GSV and SSV. PV, popliteal vein;GAS, gastrocnemius muscle; SOL, soleus muscle; GSV, great saphenous vein;...
Age is a key risk factor associated with the severity of symptoms caused by SARS-CoV-2, and there is an urgent need to reduce COVID-19 morbidity and mortality in elderly individuals. We discuss evidence suggesting that trained immunity elicited by BCG vaccination may improve immune responses and can serve as a strategy to combat COVID-19 in...
Researchers here applied three months of a methionine restricted diet to old mice, and found that it greatly reduced age-related cognitive decline, as measured in maze tests. The methionine restricted animals perform more like young animals than like their unrestricted peers. Methionine is an essential amino acid essential to all protein synthesis. Methionine sensing is one of the more important...

DAVID NIELD, 6 APRIL 2021 In terms of biological aging, the body seems to shift gears three times during our lifespans, research from 2019 suggests – with 34 years, 60 years, and 78 years being the key thresholds. In other words, there’s evidence that aging isn’t one long, continuous process that moves at the same speed throughout...
If you could stay forever young, you would probably use that opportunity. Scientists say that aging is actually a disease and should be dealt with as such. Researchers from the University of Waterloo found that there is a best time of day to take anti-aging supplements and it actually depends on your age. Aging is...

A man in his late 70s said he enjoyed going out to dinner, but was constrained by the meal preparation guidelines that...
