Cellular reprogramming and epigenetic rejuvenation
Clinical Epigenetics, 2021 Ageing is an inevitable condition that afflicts all humans. Recent achievements, such as the generation of induced pluripotent stem cells, have delivered preliminary evidence that slowing down and reversing the ageing process might be possible.

Autologous platelet concentrates for facial rejuvenation
Journal of Applied Oral Science, 2022 Autologous platelet concentrates (APCs) are promising therapeutic agents in facial rejuvenation since they are a great source of cytokines, growth factors and other biologically active substances.

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 ...

Rejuvenation and Memory in model Spin Glasses in 3 and 4 dimensions
, 2005 We numerically study aging for the Edwards-Anderson Model in 3 and 4 dimensions using different temperature-change protocols. In D=3, time scales a thousand times larger than in previous work are reached with the SUE machine.

Aging and Rejuvenation with Fractional Derivatives [PDF]
, 2004 We discuss a dynamic procedure that makes the fractional derivatives emerge in the time asymptotic limit of non-Poisson processes. We find that two-state fluctuations, with an inverse power-law distribution of waiting times, finite first moment and ...

Immune system rejuvenation—approaches and real achievements
Exploration of Immunology, 2023 Interest in the mechanisms of aging of the immune system has not faded over the past 100 years, and it is caused by the immune-mediated development of age-related pathology, including autoimmune organ damage, reduced vaccination efficiency ...

, 2006 The aging dynamics after shear rejuvenation in a glassy, charged clay suspension have been investigated through dynamic light scattering (DLS). Two different aging regimes are observed: one is attained if the sample is rejuvenated before its gelation and

Semi-independent resampling for particle filtering [PDF]
, 2017 Among Sequential Monte Carlo (SMC) methods,Sampling Importance Resampling (SIR) algorithms are based on Importance Sampling (IS) and on some resampling-based)rejuvenation algorithm which aims at fighting against weight degeneracy.

Aged hematopoietic stem cells are refractory to bloodborne systemic rejuvenation interventions
Journal of Experimental Medicine, 2021 Ho et al. demonstrate that old HSCs are extremely resistant to bloodborne systemic rejuvenation approaches and long-term exposure to a young BM niche microenvironment, maintaining a cell-intrinsic aged state.
