Taxonomic reassessment of fossil Sequoia and Protosequoia from the Upper Miocene of Central Honshu, Japan, with implications for leaf morphological variation in extant S. sempervirens

open access: yesAmerican Journal of Botany, Volume 113, Issue 7, July 2026.
Abstract Premise Since its emergence in the Mesozoic, Sequoia (Cupressaceae) has been considered to possess conserved leaf morphology. However, recent studies have shown that the leaves of extant S. sempervirens become smaller, with a scale form, with increasing tree height.

Alpinia zerumbet‐Derived Extracellular Vesicles Protect Against UVB‐Induced Photoaging by Enhancing Mitochondrial Bioenergetics and Skin Barrier Function

open access: yesBioFactors, Volume 52, Issue 4, July/August 2026.
AZEVs derived from Alpinia zerumbet leaves protect HaCaT keratinocytes from UVB‐induced photoaging by reducing reactive oxygen species (ROS) accumulation, restoring mitochondrial membrane potential, and enhancing ATP production. AZEVs upregulate mitochondrial biogenesis–related proteins, including p‐AMPK/AMPK, SIRT1, PGC‐1α, and Nrf2, thereby improving

Therapeutic Potential of Carica papaya (L.) Extract on NRF2/KEAP1 and Apoptotic Pathways in Asbestos‐Induced Lung Toxicity

open access: yesFood Science &Nutrition, Volume 14, Issue 7, July 2026.
Asbestos exposure induced oxidative stress, apoptosis, and lung tissue damage in animal models. Treatment with Carica papaya (500 mg/kg) extract improved antioxidant status, reduced oxidative stress biomarkers, and restored lung architecture. Gene expression analysis showed modulation of NRF2/KEAP1 and apoptotic pathways.
