AKR breakup and auroral particle acceleration at substorm onset [PDF]

, 2008
The dynamical behavior of auroral kilometric radiation (AKR) is investigated in connection with auroral particle acceleration at substorm onsets using high-time-resolution wave spectrograms provided by Polar/PWI electric field observations.

Association between work characteristics and epigenetic age acceleration: cross-sectional results from UK – Understanding Society study [PDF]

, 2022
Occupation-related stress and work characteristics are possible determinants of social inequalities in epigenetic aging but have been little investigated.

Photon acceleration in vacuum [PDF]

, 2006
A new process associated with the nonlinear optical properties of the electromagnetic vacuum, as predicted by quantum electrodynamics, is described. This can be called photon acceleration in vacuum, and corresponds to the frequency shift that takes place

Obesity and Accelerated Aging

The Journal of nutrition, health and aging, 2023
Abstract Obesity in the older population has increased in prevalence and incidence over the last several decades and has been associated with a decline in physical function, quality of life, and increased risk of complications from cardiometabolic diseases. Several interrelated hallmarks of aging have been proposed.

Accelerated epigenetic age at birth and child emotional and behavioura development in early childhood: a meta-analysis of four prospective cohort studies in ECHO

Epigenetics, 2023
Background: ‘Epigenetic clocks’ have been developed to accurately predict chronologic gestational age and have been associated with child health outcomes in prior work. Methods: We meta-analysed results from four prospective U.S cohorts investigating the

Vertical evolution of auroral acceleration at substorm onset [PDF]

, 2009
This study describes the onset process of auroral substorms in connection with the vertical evolution of auroral particle acceleration, on the basis of auroral kilometric radiation (AKR) dynamics.

Evaluation of Epigenetic Age Acceleration Scores and Their Associations with CVD-Related Phenotypes in a Population Cohort

Biology, 2022
We evaluated associations between nine epigenetic age acceleration (EAA) scores and 18 cardiometabolic phenotypes using an Eastern European ageing population cohort richly annotated for a diverse set of phenotypes (subsample, n = 306; aged 45–69 years ...

DNA methylation age at birth and childhood: performance of epigenetic clocks and characteristics associated with epigenetic age acceleration in the Project Viva cohort

Clinical Epigenetics, 2023
Background Epigenetic age acceleration (EAA) and epigenetic gestational age acceleration (EGAA) are biomarkers of physiological development and may be affected by the perinatal environment.

DNA Methylomes and Epigenetic Age Acceleration Associations with Poor Metabolic Control in T1D

Biomedicines, 2020
Type 1 diabetes (T1D) is an autoimmune disease that leads to insulin deficiency and hyperglycemia. Little is known about how this metabolic dysfunction, which substantially alters the internal environment, forces cells to adapt through epigenetic ...
