Serial Molecular‐Microstructural Multimodal Intravascular Imaging of Atherosclerotic Plaques in Mice

Advanced Science, EarlyView.
A novel longitudinal molecular and microstructural intravascular imaging approach is developed to study murine atherosclerosis. The technique combines a unique surgical model with a miniaturized multimodal device to detect macrophage activity and lipid simultaneously.

Comparative evaluation of isolation techniques and characterization of red pulp macrophages from pig splenocytes

Frontiers in Immunology
IntroductionRed pulp macrophages (RPMs) play a central role in iron recycling and immune regulation within the spleen, yet optimized methods for the isolation and characterization of pig RPM remain limited.MethodsWe compared two approaches for isolating ...

Mesoporous PU/PEDOT:PSS Electrodes Reveal Population‐Level Stochastic Bioelectrical Dynamics in Marine Diatoms

Advanced Science, EarlyView.
Mesoporous mixed ionic‐electronic PU/PEDOT: PSS electrodes enable label‐free detection of stochastic extracellular bioelectrical dynamics in living Phaeodactylum tricornutum. Living diatoms actively modulate interfacial ionic dynamics, establishing stochastic electrochemical noise as a sensitive probe of microbial bioelectrochemical activity and a new ...

Macrophage PABPC4‐SPP1 Axis Orchestrates Immunosuppression in Colorectal Cancer

Advanced Science, EarlyView.
In the CRC microenvironment, macrophage PABPC4 binds to the 3′UTR of SPP1 mRNA to stabilize its expression, thereby sustaining M2‐like immunosuppressive macrophage polarization. Concurrently, this axis suppresses CD8+ T cell effector functions via CD44 signaling, collectively fostering an immunosuppressive niche that drives tumor progression.

Time-Since-Deposition Signatures for Canine Blood Based on Cellular Autofluorescence

Veterinary Sciences
Animal cruelty investigations can be hampered by not knowing when a biological sample was deposited at a crime scene, i.e., the sample’s time-since-deposition (TSD). The goal of this study was to characterize a new signature system for estimating the TSD

Dual pKa Lipid Nanoparticles for Lung‐tropic mRNA Delivery and pH‐Programmed Endosomal Escape

Advanced Science, EarlyView.
Lipid nanoparticles’ bottleneck lies in low endosomal escape efficiency and liver‐dominant delivery after intravenous administration. To overcome these limitations, we present a stepwise pH‐programmed lipid nanoparticle system enabled by our newly synthesized ionizable lipid.

Ultrafast Micrometric Laser Structuring of Polymer Surfaces for Highly Organized Skeletal Muscle Tissue Modeling. [PDF]

Adv Sci (Weinh)
Standard cell culture supports were functionalized by laser‐structuring to generate advanced topographies tailored to skeletal muscle tissue. The physicochemical modifications of the polymeric surfaces and their interactions with cells were thoroughly investigated, confirming both safety and effectiveness in guiding muscle cell organization.

Mesenchymal Stromal Cell‐Based Cell–Drug Conjugates for the Treatment of Acute Liver Failure

Advanced Science, EarlyView.
Mesenchymal stromal cell (MSC)‐based cell‐drug conjugates are constructed by anchoring rosiglitazone‐loaded nanoparticles onto the MSC surface. Sustained rosiglitazone release enhances MSC proliferation and paracrine activity while promoting anti‐inflammatory macrophage polarization.
