Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

open access: yesIntegrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

Effect of organic biocolourants on lightfastness and mechanical properties of polylactic acid

open access: yesColoration Technology, EarlyView.
Abstract Most modern colourants are acquired from petroleum‐based sources or mining, which often causes environmental degradation. Consequently, alternative colouring solutions are sought, such as using biocolourants, which are organic colourants from bio‐based sources.

New alternatives in photoprotection: Preparation and evaluation of lamellar silicate derivatives and their use as sunscreens

open access: yesInternational Journal of Cosmetic Science, EarlyView.
The use of nanotechnology in sunscreens has increased, with various filters and organoclays tested for new intercalated formulations. As animal toxicity tests decrease, New Approach Methodologies are favoured. The S4 + OMC‐NC improved cell survival under SSL and showed antimutagenic properties, making it a promising candidate for safe photoprotection ...

Populus PtrbHLH011 Is a Transcriptional Co‐Regulator Involved in the Activation of Cell Wall Biosynthesis by Iron Deprivation

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The lack of a mechanistic understanding of the environmental plasticity of secondary cell wall (SCW) biosynthesis restricts large‐scale biomass and bioenergy production on marginal lands. Using Populus (poplar), a key bioenergy crop, we discovered that iron deprivation, a prevalent abiotic stress on marginal lands, stimulates SCW biosynthesis ...

Reduced dietary intake induces body fluid hypotonicity via alterations in water and energy metabolism

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Overnight reduced dietary intake (RED; small dinner with skipped breakfast), compared to a sufficient dietary condition (CON), induced body fluid hypotonicity during moderate exercise in a hot environment, despite equal total fluid intake. RED led to lower serum osmolality and reduced urinary sodium excretion, without differences

Photocatalytic Co‐Reduction of CO2 and Nitrate over Porphyrin Metal–Organic Frameworks: Dual Atomic Active Site and Nanostructure Synergy Enhances C–N Coupling for Urea Production

open access: yesAngewandte Chemie, Volume 137, Issue 41, October 6, 2025.
A bimetallic porphyrin metal–organic framework with nanoflower‐like architecture is synthesized as a high‐performance photocatalyst for urea synthesis. The synergy between dual atomic active sites and nanostructure engineering enables an excellent performance with a urea yield of 2459.8 µg h−1 gcat−1 via photocatalytic co‐reduction of CO2 and nitrate ...
