Advanced Science, EarlyView.This study reveals histone lactylation as a metabolic‐epigenetic regulator countering cellular senescence and skeletal muscle aging. Reduced lactylation impairs cell cycle, DNA repair and proteostasis pathways, while exercise restores glycolytic activity and lactylation levels, preserving muscle function.

Protein aggregation and neurodegenerative disease: Structural outlook for the novel therapeutics
Proteins: Structure, Function, and Bioinformatics, EarlyView., 2023 Abstract Before the controversial approval of humanized monoclonal antibody lecanemab, which binds to the soluble amyloid‐β protofibrils, all the treatments available earlier, for Alzheimer's disease (AD) were symptomatic. The researchers are still struggling to find a breakthrough in AD therapeutic medicine, which is partially attributable to lack in ...

Inhibition of Ferroptosis Delays Aging and Extends Healthspan Across Multiple Species
Advanced Science, EarlyView.This study identifies ferroptosis as a key driver of cellular senescence, with its inhibition delaying aging and extending healthspan across species. During senescence, ferroptosis worsens, increasing oxidative stress and lipid peroxidation, which accelerate aging.

Supramolecular Gels as Active Tools for Reaction Engineering
Angewandte Chemie, EarlyView.The unique combination of environments within gels, self‐assembled from low‐molecular‐weight gelators, offers the ability to control reactivity in new ways, achieving unique reaction outcomes, leading to the emerging concept of supramolecular gels as nanoreactors. Smart chemical engineering methods enable the use of such gels to fabricate materials and

Dynamics of glucose-lactose diauxic growth in E. coli [PDF]
arXiv, 2007 We present a mathematical model of glucose-lactose diauxic growth in Escherichia coli including both the postive and negative regulation mechanisms of the lactose operon as well as the inducer exclusion. To validate this model, we first calculated the time evolution of beta-galactosidase for only the lactose nutrient and compared the numerical results ...

Biocatalytic approaches using lactulose: end product compared with substrate [PDF]
, 2016 Lactulose is a lactose-based carbohydrate with well-known prebiotic effect and recognized medical applications. Currently, the commercially available lactulose is chemically synthesized. Nevertheless, the process leads to low yields and high levels of by-

Advanced Science, EarlyView.Facet joint osteoarthritis (FJOA), prevalent in the elderly, involves Talin2 upregulation promoting ECM degradation while suppressing synthesis. Mechanical load stabilizes Talin2 via OTUB1‐mediated non‐canonical deubiquitination, driving CCL2 expression that recruits immune cells, exacerbating inflammatory joint degeneration.
