Multifunctional Catechol‐Functionalized Cellulose Hydrogels for the Minimally Invasive Treatment of Acute Optic Nerve Injuries

Advanced Healthcare Materials, EarlyView.
Catechol‐functionalized cellulose hydrogels are developed as injectable, bioadhesive platforms for retinal neuroprotection. The hydrogels exhibit tunable rheological and mechanical properties, strong tissue adhesion, and sustained antioxidative activity.

Mechanistic and biological characterisation of novel N5-substituted paullones targeting the biosynthesis of trypanothione in Leishmania

Journal of Enzyme Inhibition and Medicinal Chemistry, 2020
Trypanothione synthetase (TryS) produces N1,N8-bis(glutathionyl)spermidine (or trypanothione) at the expense of ATP. Trypanothione is a metabolite unique and essential for survival and drug-resistance of trypanosomatid parasites. In this study, we report

Tomographic Printing in a Chip: A Versatile Platform for Biomimetic 3D Organ‐on‐Chip

Advanced Healthcare Materials, EarlyView.
A novel light‐based bioprinting approach, TVAM‐in‐a‐chip, enables rapid, contactless fabrication of biomimetic 3D organ‐on‐chip devices directly within preassembled microfluidic platforms. This strategy supports diverse materials, including cell‐laden resins, and eliminates post‐assembly steps.

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

Advanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Kinetic and thermodynamic study of a traditional dye as catalyst for thiol oxidation in sour kerosene

Al-Qadisiyah Journal for Engineering Science
The oxidation process of thiols is industrially used to treat light petroleum products in the presence of a supported catalyst. A low-cost, traditional dye, cobaltous phthalocyanine salt, was used as the active component for catalyst preparation.

Oxidative modification of proteins: An emerging mechanism of cell signaling

Frontiers in Physiology, 2012
There are a wide variety of reactive species which can affect cell function, including reactive oxygen, nitrogen, and lipid species. Some are formed endogenously through enzymatic or non-enzymatic pathways, and others are introduced through diet or ...

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Effects of thiol compounds on DNA-damage detection and in vitro fertilization outcomes in bovine sperm

The Journal of Reproduction and Development
Reduced glutathione (GSH), a thiol compound, plays an important role in protecting sperm from excessive levels of reactive oxygen species. Our previous study demonstrated that GSH supplementation was associated with improved in vitro ...
