Photochemistry and Photobiology, EarlyView.This study explored the role of a novel microcapsule composite Spherulites Peony Superior Retinol (SPSR) on skin damage induced by UVB. The results of in vitro and human efficacy assays further demonstrate that SPSR is beneficial in replenishing skin hydration, promoting epidermal cell growth, soothing skin redness and sensitivity, reducing ROS ...

Conditions for the formation of anomalous tail of comet
Open Astronomy, 2019 The time and velocity of ejection of dust particles of anomalous tails from cometary nuclei are determined. It is revealed that some comets cause the formation of an anomalous tail is the collision of their comet nucleus with other bodies of the Solar ...

The microbiologist's guide to metaproteomics
iMeta, Volume 4, Issue 3, June 2025.Metaproteomics within the multi‐omics framework provides a comprehensive view of microbial systems by identifying proteins, quantifying their levels, detecting posttranslational modifications (PTMs), mapping protein–protein interactions (PPIs), and localizing proteins.
