Nitrogen‐Boosted H2O2 Production of Arginine‐Polyphenol Nanozyme Drives Oxidative Eustress for Hair Regeneration

open access: yesAdvanced Science, EarlyView.
PEA nanoenzymes are assembled from L‐arginine and EGCG. The nitrogen element in arginine enhances the thermodynamic feasibility of H2O2 production through PEA's oxygen reduction catalysis, enabling nitrogen‐dependent H2O2 release. Intradermal delivery of PEA via microneedles promotes efficient H2O2 synthesis, thereby stimulating regrowth in telogen ...

Comparison of indices for the prediction of nitrogen mineralization after destruction of managed grassland [PDF]

open access: yes, 2010
Intensively managed grasslands are occasionally chemically killed with herbicide and ploughed in order to grow an arable crop. After this management, large N mineralization rates with large losses to the environment are commonly observed.

Metarhizium anisopliaeMitigates the Phytotoxicity of Lead and Nanoplastics on Rice by Modifying Physiological, Transcriptomic, Metabolomic Activities, and Soil Microbiome

open access: yesAdvanced Science, EarlyView.
Metarhizium anisopliae alleviates the phytotoxic effects of polyethylene nanoplastics (NP) and lead (Pb) in rice by decreasing Pb uptake, restoring antioxidant and hormonal equilibrium, and promoting growth. Additionally, the fungus modifies the rhizosphere microbiota, enhancing both contaminant tolerance and plant growth, thereby effectively ...

Effect of grazing intensity and dung on herbage and soil nutrients

open access: yesPlant, Soil and Environment, 2019
Dung deposited by grazing animals is a key driver affecting sward structure and nutrient cycling in pastures. We tested herbage and soil properties in three types of tall sward-height patches (> 10 cm): (i) patches with dung under intensive grazing ...

The effect of different levels of spring grass supply and stocking rate on the performance and intake of cows in early lactation [PDF]

open access: yes, 2008
End of project reportGrazed herbage can supply nutrients to dairy cows at a lower cost than alternative feeds (Shalloo et al., 2004). Therefore, the objective of pasture-based systems must be to maximize the proportion of grazed grass in the diet of the ...

ROS‐Responsive Wedelolactone Hydrogel Promotes Intervertebral Disc Repair by Disrupting the NF‐κB–LCN2 Inflammatory Feedback Loop

open access: yesAdvanced Science, EarlyView.
A mechanically robust, ROS‐responsive hydrogel is engineered to treat intervertebral disc degeneration by targeting the NF‐κB–LCN2 inflammatory feedback loop. By delivering wedelolactone specifically within oxidative niches, this system disrupts macrophage–disc cell crosstalk.

THE EFFECT OF ROTATIONAL GRAZING ON FLORISTIC COMPOSITION AND YIELD OF Ranunculo repentis – Alopecuretum pratensis HILLY GRASSLAND [PDF]

open access: yesJournal of Central European Agriculture, 2004
In the years 2001 and 2002 the effect of the introduction of the whole year rotational grazing with different post-grazing target sward heights (4 cm in the treatment 1, and 7 cm in the treatment 2) on the yield and changes in floristic composition of ...

Interaction among fire and sward height increases leaf nitrogen per unit area of annual ryegrass in subtropical grasslands from southern Brazil [PDF]

open access: yesCiência Rural
: Fire is one of the main drivers of vegetation structure from terrestrial ecosystems and its effects on plants allocation resources and biomass are mediated by leaf functional traits. These attributes can provide useful information for future management
