Adolescent Exposure to a THC‐Rich Cannabis Extract Produces Genotype‐Dependent Effects on Cognition and Glial Morphology in Serine Racemase Mutant Mice

Journal of Neurochemistry, Volume 170, Issue 9, September 2026.
Adolescent exposure to a THC‐rich cannabis extract produced genotype‐dependent, contrasting effects in mice. In wild‐type animals, it altered behavior and brain glial cell structure, whereas in mice with a genetic deficiency in serine racemase, a model of impaired NMDA receptor signaling relevant to schizophrenia, it prevented cognitive and ...

Stimuli‐Responsive Silsesquioxane Nanozymes for Organocatalysis in Water and Prodrug Activation in Cells

Angewandte Chemie, Volume 138, Issue 21, 18 May 2026.
Amino‐bearing silsesquioxanes are water‐stable nanozymes that exhibit aggregation‐ and disaggregation‐dependent catalysis and can be applied to intracellular prodrug activation for cancer therapy. ABSTRACT Synthetic nanozymes have emerged as promising alternatives to natural enzymes for catalytic and therapeutic applications, yet their limited ...

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.

Application of Ag‐Enriched Nanostructures Through Ga+ Irradiation of Silver Butyrate Films in Surface‐Enhanced Raman Spectroscopy (SERS)

Small Methods, Volume 10, Issue 15, 7 August 2026.
We report a direct‐writing method for patterning silver‐enriched nanostructures with dual functionality: High electrical conductivity, with a resistivity of 95 µΩ·cm, and strong SERS activity, achieving enhancement factors exceeding 107. This approach enables an easy and cost‐effective alternative for the production of microstructures with applications

Synthesis, Characterization, and Optical Properties of Undoped and Te‐Doped W(SxSe(1−x))2 and Core‐Shell WS2@W(SxSe(1−x))2 Nanotubes

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.
W(SxSe1−x)2, Te:WSSe, and WS2@WSSe nanotubes were synthesized through controlled precursor composition. The W(SxSe1−x)2 and Te:WSSe nanotubes exhibit small‐diameter (<30 nm), high‐yield, and well‐defined excitonic transitions. Composition tuning via S/Se ratios increases interlayer spacing with higher Se content. The incorporation of Te remains limited

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy

Advanced Functional Materials, Volume 36, Issue 45, 5 June 2026.
This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.
