Moreover, in very old patients, the accumulation

of % CST may impair intracellular zinc homeostasis and metallothioneins expression, which itself is linked to an increased number of inflammatory agents, thereby suggesting the existence of a possible causal relationship between % CST and zinc homeostasis. The determination of % CST could be a more reliable means than the simple measure of telomere length as fundamental parameter in ageing to determine whether individuals are still able to respond to stress.”
“Telomeres in somatic cells become shorter with aging, and the shortening is accelerated by pathophysiological conditions. Telomere shortening can be influenced by subtelomeric DNA selleck methylation. The telomere length and subtelomeric methylation status in peripheral leukocytes were compared in healthy controls and sarcoidosis patients. The sarcoidosis patients revealed shorter telomeres and a faster attrition of telomere shortening in comparison with healthy controls. Both healthy controls

and sarcoidosis patients showed that long telomeres (> 9.4 kb) decrease and short telomeres (< 4.4 kb) increase with aging, accompanying relative increases of long telomeres with subtelomeric hypermethylation and short telomeres with subtelomeric hypomethylation. This suggested that the aging-related telomere shortening is associated with the surrounding subtelomeric hypomethylation. Furthermore, sarcoidosis patients showed this alteration of the subtelomeric

methylation earlier than controls (in their 60s or later). This altered subtelomeric hypomethylation may correspond to the accelerated telomere shortening in sarcoidosis. This also means that the subtelomeric hypomethylation can be also influenced by certain disease conditions.”
“This study compared measures of chronic Trichostatin A research buy pain, for example, number of pain sites and overall pain severity, in relation to lower extremity function in the older population.

Six hundred older adults (mean age 77.9 years, 64% female) were queried about presence of chronic pain. Number of pain sites was categorized as none, single site, multisite, or widespread. Pain severity was measured in quartiles of the Brief Pain Inventory pain severity subscale. Lower extremity function was assessed by the Short Physical Performance Battery (SPPB), a composite measure of gait speed, balance, and chair stands.

Many older persons reported multisite or widespread pain (40%). Increased pain sites and pain severity were associated with poorer SPPB performance after adjusting for age, sex, height, and weight. With further adjustment for education, comorbid conditions, and depressive symptoms, multisite pain (p < .001) and most severe pain (p < .05) were associated with poorer SPPB performance, but assessed together in the same model, only the association with multisite/widespread pain remained significant (p < .01).
