In conclusion, long-term cumulative BP was associated with subsequent cognitive decline, dementia risk, and all-cause mortality in cognitively healthy adults aged ≥50 years. Efforts are required to control long-term systolic BP and pulse pressure and to maintain adequate diastolic BP.
Longer-Lived Mammals Tend to Have Lower Expression of Inflammation-Related Genes

Researchers here make a few interesting observations on gene expression data from a range of mammalian species with very different life spans. Longer-lived species exhibit weaker inflammatory responses and more effective DNA repair, for example. Chronic inflammation is a feature of aging, as the immune system reacts to molecular damage and the presence of increasing numbers of senescent cells. Unresolved inflammatory signaling is disruptive to cell behavior and tissue function throughout the body, and is implicated in the onset and progression of all of the common age-related conditions.
Researchers compared the gene expression patterns of 26 mammalian species with diverse maximum lifespans, from two years (shrews) to 41 years (naked mole rats). They identified thousands of genes related to a species' maximum lifespan that were either positively or negatively correlated with longevity. They found that long-lived species tend to have low expression of genes invol...
