Altered cytoskeletal arrangement in induced pluripotent stem cells and motor neurons from patients with riboflavin transporter deficiency

Disease Models & Mechanisms, 2021
The cytoskeletal network plays a crucial role in the differentiation, morphogenesis, function and homeostasis of the nervous tissue, so that alterations in any of its components may lead to neurodegenerative diseases.

Genipin‐Crosslinked, Silane‐Anchored 3D Tumor–Stroma Microtissues for High‐Content On‐Chip Drug Testing

Advanced Healthcare Materials, EarlyView.
We describe a microfluidic tumor‐stroma co‐culture model, engineered to resist collagen‐hydrogel contraction driven by fibroblast activity. Surface silanization with APTES covalently anchors the matrix to the chip, while Genipin crosslinking progressively increases stiffness and elasticity without harming cells. This supports >10 days of co‐culture and

N, S Co‐Doped Carbon Quantum Dots‐Riboflavin Composite Photosensitizers for Enhanced Iontophoresis‐Assisted Corneal Cross‐Linking

Advanced Science, EarlyView.
This study explores the use of N, S co‐doped carbon quantum dots (NS‐CQDs) as carriers for riboflavin, creating NS‐CQDs‐RF composite photosensitizers. These composites improve riboflavin absorption, enhance ROS generation efficiency, and preserve corneal epithelium integrity.

Dual‐Responsive Dynamic Covalent Bond‐Based Assembly of Lipid‐Nanozyme Systems via Multi‐Target Synergy and Efficient Target Enrichment for Ischemic Stroke Therapy

Advanced Science, EarlyView.
This system adopts a biomimetic phospholipid structure, covalently binding iNOS inhibitors, neuroprotective agent PCA and vitamin E derivatives through pH/ROS dual‐responsive bonds, and assembles them with Prussian blue nanozyme to form PBB@AHA. It can efficiently penetrate the blood‐brain barrier and simultaneously release multiple active components ...

Riboflavin deficiency in the rat: Effects on iron utilization and loss [PDF]

, 1991
Iron absorption and daily loss of Fe were measured in riboflavin-deficient (B2-) Norwegian hooded rats and controls (B2+). Animals were fed on a test meal extrinsically labelled with 59Fe and whole-body radioactivity measured for 15 d.

Effects of riboflavin deficiency and riboflavin administration on carcinogen-DNA binding

, 1993
A study was conducted to assess the effects of riboflavin deficiency and riboflavin supplementation on carcinogen-DNA binding. After 12 wk on a riboflavin-sufficient or a riboflavin-deficient diet male Wistar rats were administered 3H-labelled benzo[a ...

A Sprayable Nanoplatform Breaks the Vicious Cycle of Diabetic Wounds via Photoactivated Antioxidant and Drug Delivery

Advanced Science, EarlyView.
A sprayable near‐infrared‐activated nanoplatform incorporating MXene, ZnHCF nanozyme, and deferoxamine efficiently breaks the vicious cycle of diabetic wounds. Upon irradiation, interfacial electron transfer and photothermal effects enhance multi‐enzyme activity, enabling explosive ROS elimination, alleviation of hypoxia, and controlled DFO release ...
