Prevention of Protein Glycation by Natural Compounds [PDF]
, 2015 Non-enzymatic protein glycosylation (glycation) contributes to many diseases and aging of organisms. It can be expected that inhibition of glycation may prolong the lifespan.

Deforming glassy polystyrene: Influence of pressure, thermal history, and deformation mode on yielding and hardening [PDF]
, 2009 The toughness of a polymer glass is determined by the interplay of yielding, strain softening, and strain hardening. Molecular-dynamics simulations of a typical polymer glass, atactic polystyrene, under the influence of active deformation have been ...

Skeletal muscle as an experimental model of choice to study tissue aging and rejuvenation. [PDF]
, 2020 Skeletal muscle is among the most age-sensitive tissues in mammal organisms. Significant changes in its resident stem cells (i.e., satellite cells, SCs), differentiated cells (i.e., myofibers), and extracellular matrix cause a decline in tissue ...

Gamete Formation Resets the Aging Clock in Yeast [PDF]
, 2018 Gametogenesis is a process whereby a germ cell differentiates into haploid gametes. We found that, in budding yeast, replicatively aged cells remove age-induced cellular damage during gametogenesis.

Dill extract induces elastic fiber neosynthesis and functional improvement in the ascending aorta of aged mice with reversal of age-dependent cardiac hypertrophy and involvement of lysyl oxidase-like-1 [PDF]
, 2020 Elastic fibers (90% elastin, 10% fibrillin-rich microfibrils) are synthesized only in early life and adolescence mainly by the vascular smooth muscle cells through the cross-linking of its soluble precursor, tropoelastin.

Effect of physical aging on the low-frequency vibrational density of states of a glassy polymer
, 2003 The effects of the physical aging on the vibrational density of states (VDOS) of a polymeric glass is studied. The VDOS of a poly(methyl methacrylate) glass at low-energy (

More oxygen during development enhanced flight performance but not thermal tolerance of Drosophila melanogaster [PDF]
, 2017 High temperatures can stress animals by raising the oxygen demand above the oxygen supply. Consequently, animals under hypoxia could be more sensitive to heating than those exposed to normoxia.

Mesoscopic real space structures in aging spin-glasses: the Edwards-Anderson model [PDF]
, 2018 Isothermal simulational data for the 3D Edwards-Anderson spin glass are collected at several temperatures below $T_{\rm c}$ and, in analogy with a recent model of dense colloidal suspensions,interpreted in terms of clusters of contiguous spins overturned
