Multimodal Optical Imaging and Modulation with Simultaneous Electrophysiology Through Smart Dura in Non‐Human Primates

Advanced Science, EarlyView.
This study demonstrates multimodal integration in non‐human primates, combining large‐scale, high‐density electrophysiology using Smart Dura with optical techniques such as multiphoton imaging (MPI), photothrombotic lesioning, optical coherence tomography angiography (OCTA), wide‐field intrinsic signal optical imaging (ISOI), and optogenetics.

Deciphering and Targeting the Schwannoma‐Neuron‐Macrophage Crosstalk for the Treatment of Schwannomatosis and Associated Pain

Advanced Science, EarlyView.
We established patient‐derived SWN cell lines and orthotopic PDX models that recapitulate patient pain phenotypes, alongside a novel intravital DRG imaging platform to track macrophage infiltration and neuronal pain responses. Using these models, we define HMGB1–CCL2–IL‐6 signaling crosstalk driving pain and identify EGF signaling as a key regulator of

EFECTO DE DIFERENTES MÉTODOS DE LIMPIEZA EN MATERIALES PARA PRÓTESIS DENTALES REMOVIBLES

, 2018
The purpose of this study is to evaluate the effects of different cleaners on the surfaces of removable dental prostheses. Two different prosthetic materials (acrylic resin and polyamide) were subjected to various cleaning methods and subsequently analyzed with a roughness tester and observed with the scanning electron microscope (SEM).

Ultrasound Modulation of Visual Circuits in Mice Independent of Auditory Confound

Advanced Science, EarlyView.
In this study, Qiu et al. found that low‐intensity ultrasound can directly activate sparse ultrasound‐sensitive neurons (UNs) in the primary visual cortex (V1) of deafened mice. The proportion of these sparse UNs is pressure‐dependent. Furthermore, ultrasound modulates visual circuitry with distinct excitatory and inhibitory effects.

Radical‐Mediated, Substrate‐Independent Fabrication of Hybrid Solid–Hydrogel Materials With Tunable Crosslinking: An Initiator‐ and Crosslinker‐Free Approach

Advanced Science, EarlyView.
This work introduces a substrate‐independent, reagent‐free plasma strategy that forms radical‐rich interlayers for covalent hydrogel attachment without initiators or crosslinkers. The long‐lived radicals drive in situ gelation, creating robust, cytocompatible hybrid solid–hydrogel constructs across diverse substrates.

Etablering av kvantitativ lekkasjemodell for dentale fyllingsteknikker og -materialer

, 2012
I oppgaven har vi etablert en fysisk modell for kvantitative tetthetsmålinger av dentale fyllingsmaterialer, og testet denne på utvalgte rotfyllingsmaterialer. Fokuset har vært på fremstillingen av denne modellen. Modellen er ferdig og vi har testet den på noen grupper med rotfylte tenner. Et gjennomgående problem er stor variasjon i test-resultater av
