Tunable Regional Targeting of Self‐Assembling Peptide Nanomaterials in Acute Myocardial Infarction

open access: yesAdvanced NanoBiomed Research, EarlyView.
In a rat model of acute myocardial infarction, intravascular delivery of peptide nanofibers with a collagen‐targeting peptide bound to the infarct vasculature while globular peptide nanoparticles penetrated into the infarct area. This study demonstrated that size, shape, and surface chemistry of nanomaterials control the delivery location within the ...

Plasma–Kinetic Coupling and Redox Mechanisms in the Degradation of Acid Red 51 by Atmospheric Corona Discharge

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the degradation of the xanthene dye Acid Red 51 (ARE‐51) using atmospheric‐pressure corona discharge plasma, integrating electrical characterization, optical emission spectroscopy (OES), kinetic modeling, and physicochemical analysis to establish a unified plasma–liquid interaction framework. A degradation efficiency of

Proto‐Panic Modulation by Caffeine‐Proteinoid Complexes

open access: yesJournal of Applied Polymer Science, EarlyView.
Caffeine–proteinoid microspheres synthesized by thermal polymerization exhibit compartmentalized drug loading with encapsulation efficiencies of 61%–82% and triphasic release kinetics. Electrochemical monitoring reveals multi‐scale oscillatory dynamics consistent with chaotic and damped harmonic behavior, while Boolean logic operations demonstrate ...

Comparative Analysis of Salmonella typhimurium‐Induced Transcriptomic Changes in the Spleen of Beijing‐You Chickens and Guang Ming Broilers

open access: yesAnimal Research and One Health, EarlyView.
This study analyzed the spleen transcriptomes of different chicken breeds, identified key differentially expressed genes (EGR1, FOS, and DUSP1) that regulate resistance to Salmonella infection, and elucidated the underlying regulatory mechanisms, thereby providing new targets for disease‐resistant breeding in poultry.
