Self‐Propelled HPB@Lip@AB Nanomotors Ameliorate Dry Eye Disease

Advanced Science, EarlyView.
A self‐propelled HPB@Lip@AB nanomotor system is developed for dry eye disease (DED) therapy, facilitating rapid penetration across ocular surface barriers while integrating hydrogen therapy with multi‐enzyme‐like antioxidant activity. The nanoplatform restores mitochondrial function, suppresses oxidative stress, inflammation, and apoptosis, and ...

THE HISTOCHEMICAL DEMONSTRATION OF ENZYMATIC ACTIVITY BY A NONENZYMATIC REDOX REACTION. REDUCTION OF TETRAZOLIUM SALTS BY INDOLYL-3-ACETALDEHYDE

, 1960
The availability of synthetic indolyl-3-acetaldehyde has made possible the determination of the mechanism of reduction of tetrazolium salts in the tryptamine-tetrazolium technique for the demonstration of monoamine oxidase activity.

Dual Repression by IPA1 Fine‐Tunes OsbZIP79‐Mediated Salt Tolerance in Rice

Advanced Science, EarlyView.
Dual repression by IPA1 fine‐tunes OsbZIP79‐mediated salt tolerance in rice: direct transcriptional inhibition under normal conditions and salt‐induced degradation under stress. This dual mechanism activates OsbZIP79 to regulate Na+/K+ homeostasis and redox balance via downstream genes, enabling optimal salt stress response.

Integration of the D‐Genome Reshapes Gene Transcription, Chromatin Architecture, and Metabolome of Allohexaploid Wheat, Leading to Enhanced Environmental Adaptability

Advanced Science, EarlyView.
Integration of the D‐genome reshapes gene transcription, chromatin architecture, and the metabolome of hexaploid wheat, leading to enhanced adaptability to salt, UV‐B, and alkali stress. ABSTRACT The hybridization‐led integration of the D‐genome into domesticated tetraploid wheat gave rise to allohexaploid wheat, the most cultivated wheat globally ...

Ultrafast Micrometric Laser Structuring of Polymer Surfaces for Highly Organized Skeletal Muscle Tissue Modeling

Advanced Science, EarlyView.
Standard cell culture supports were functionalized by laser‐structuring to generate advanced topographies tailored to skeletal muscle tissue. The physicochemical modifications of the polymeric surfaces and their interactions with cells were thoroughly investigated, confirming both safety and effectiveness in guiding muscle cell organization.
