Microscopía confocal en el análisis de lesiones cutáneas equívocas en la práctica clínica habitual

ANALES RANM
Introducción y objetivos: La dermatoscopia es una técnica in vivo no invasiva que consiste en la evaluación de lesiones cutáneas mediante una lente de aumento y un sistema de iluminación, haciendo traslúcida la capa córnea.

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.

Copper–Collagen Interactions Regulate the Mechanical and Invasive Properties of Tumor Spheroids

Advanced Healthcare Materials, Volume 15, Issue 22, 12 June 2026.
Ionic copper is investigated as a modulator of tumor spheroid growth and invasiveness in a 3D microfluidic glioblastoma model. Copper exposure alters metabolic activity, cytoskeletal organization, protrusion dynamics, and EMT‐related phenotypes in a dose‐ and timing‐dependent manner, revealing how copper bioavailability shapes tumor aggressiveness ...

Targeted Delivery of mRNA to the Heart via Extracellular Vesicles or Lipid Nanoparticles

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
ABSTRACT Efficient and specific delivery of mRNA to target tissues is critical for maximising therapeutic benefits while minimising off‐target effects and systemic toxicity. Systemic administration of mRNA using lipid nanoparticles (LNPs) or extracellular vesicles (EVs) typically leads to predominant accumulation in the liver.

Making the invisible visible: A global examination of careers and recognition for Imaging Scientists in core facilities

Journal of Microscopy, Volume 302, Issue 3, Page 274-294, June 2026.
Abstract Imaging facilities underpin a growing share of modern life‐science research, yet the career conditions and scholarly recognition of the Imaging Scientists in core facilities who design, deliver, and interpret imaging research remain uneven. This mismatch has previously been shown to risk loss of expertise, reduced service quality, and weaken ...
