Shape‐Memory Collagen/Silk‐Fibroin Scaffold for Dura Sealing and Skull Base Regeneration

open access: yesSmall, EarlyView.
ABSTRACT When a skull base defect occurs, reconstruction is typically performed using a variety of autologous grafts, flaps, or synthetic materials. Failure to achieve appropriate management and closure can lead to serious consequences, such as cerebrospinal fluid (CSF) leakage and subsequent meningitis.

A Novel Antioxidant Peptide Cath‐Np Derived from Nanorana parkeri Attenuates UVB‐Induced Skin Photodamage in Mice

open access: yesIntegrative Zoology, EarlyView.
Schematic representation of Cath‐Np as an antioxidant suppressing acute skin damage caused by ultraviolet B (UVB) radiation in mice. Cath‐Np inhibits the activation of p53 and mitogen‐activated protein kinase pathways while it activates the Nrf2 pathway by its strong antioxidant effects, and accordingly suppresses the expression of inflammatory factors

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.
