Advanced 3D Platforms for Modeling CNS Neuroinflammation: Cell Integration, Techniques, and Challenges

open access: yesAdvanced Healthcare Materials, EarlyView.
This review summarizes the roles of key central nervous system cell types, the extracellular matrix, and the blood‐brain barrier in neuroinflammation, and their integration into diverse 3D culture systems. It examines major incorporation strategies, including direct co‐culture, hydrogel encapsulation, transwell migration assays, and bioprinting ...

Chalcolithic and Middle Bronze Age obsidian industries at Karmir Sar: A mountain view on the lithic economies of the Southern Caucasus

open access: yesJournal of Lithic Studies, 2018
The high-altitude site of Karmir Sar is located around 2850 m a.s.l. on the southern slopes of Mt. Aragats (Armenia). Numerous stone structures (including vishaps, cromlechs, stone enclosures) are found all over the 40 ha-sized meadow, out of which three

Automating Vascular Biology: An End‐to‐End Automated Workflow for High‐Throughput Blood Vessel‐on‐a‐Chip Production and Multi‐Site Validation

open access: yesAdvanced Healthcare Materials, EarlyView.
AngioPlate384 is a 384‐well open‐top platform that automates production of more than 100 miniaturized, perfusable blood vessels embedded in hydrogel and supported by stromal cells. Stromal‐endothelial co‐culture strengthens blood vessel barrier function and yields responses useful for translational planning. Scalable and automation‐ready, it suits drug

A Tri‐Culture Heart‐on‐a‐Chip Platform With iPSC‐Derived Cardiac Cells for Predictive Cardiotoxicity Testing

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents the first entirely isogenic heart‐on‐chip, unifying cardiomyocytes, fibroblasts, and endothelial cells from a single iPSC source. The platform reveals a critical biological insight: the endothelium actively shields cardiac tissue from drug‐induced toxicity, challenging the predictive accuracy of conventional, avascular models for ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Small tools within Mode 2 technology in the Lower Palaeolithic of Italy: use-wear analysis of the chipped stone tools assemblage of the Latium site of Fontana Ranuccio (Italy)

open access: yesIpoTESI di Preistoria, 2019
Recent technological studies of lithic assemblages from Levantine and European Late Lower Palaeolithic showed that the small size flakes (small tools) found in many sites of this period are relevant technological elements.

Poking Pluripotency: Nanoinjection Into Human iPSCs

open access: yesAdvanced Materials, EarlyView.
Nanoinjection into hiPSCs: silicon nanotubes effectively transfect human induced pluripotent stem cells (hiPSCs) with mRNA, enabled by a delayed extracellular matrix application and enhanced surface functionalization. Nanoinjection is demonstrated with several reporter mRNA, including co‐transfection of mCherry and GFP.
