The Aging Blood: Cellular Origins, Circulating Drivers, and Therapeutic Potential

Aging and Cancer, EarlyView.
As a conduit linking all organs, the blood system both reflects and actively drives systemic aging. This review highlights how circulating pro‐aging and antiaging factors and age‐associated hematopoietic stem cell dysfunction contribute to immunosenescence and multi‐organ decline, positioning the hematopoietic system as a target for aging intervention.

Polymers used as viscosity index improvers: A comparative study

Polymer Testing, 1993
Abstract Ethylene-propylene copolymers and hydrogenated styrene-diene copolymers were used for a comparative study aiming at their application as viscosity index improvers in multigrade engine oils. The variation of viscosity with temperature has been evaluated as a function of the polymer concentrations.
