A type of conductive graphite/cellulose composite film used for chemical vapor-sensing material was prepared at room temperature in the ionic liquid 1-butyl-3-methylimidazolium chloride ([BMIm]Cl). Graphite was pretreated with both oxidation and reduction processes. Due to the use of N,N-carbonyldiimidazole (CDI), as a covalent cross-linking agent in [BMIm]Cl, there were limited chemical bonds ...

The influence of two thermoresponsive polymers, poly(N-isopropylacrylamide) (PNIPAM) and poly(N-vinylcaprolactam) (PVCL), on the phase transition behavior of a thermoresponsive ionic liquid, tributylhexylphosphonium 3-sulfopropylmethacrylate ([P4,4,4,6][MC3S]), was investigated. An obvious distinction was observed in the LCSTs and morphologies of [P4,4,4,6][MC3S]-PNIPAM and [P4,4,4,6][MC3S]-PVC...

Abstract Background Neurovascular contact (NVC) is the main cause of primary trigeminal neuralgia (PTN); however, cases PTN without NVC are still observed. In this study, Meckel cave (MC) morphology in were analyzed by radiomics and compared to healthy controls (HCs) explore PTN. Methods We studied 3.0T MRI data 115 patients with 46 HCs. Bilateral MC was modeled using 3D Slicer software, morpho...

This work focuses on the pH-triggered disassembly of supramacromolecular microgels, which are composed temperature-responsive poly(N-vinylcaprolactam) (PVCL) and natural polyphenol tannic acid (TA). A systematic investigation microgel formation demonstrates that a retarded addition during semi-batch precipitation polymerization influences yield, chemical composition, properties microgels to gre...

A force, humidity, and temperature-responsive electronic skin is presented by combining piezoelectric zinc oxide (ZnO) poly-N-vinylcaprolactam-co-di(ethylene glycol) divinyl ether hydrogel into core-shell nanostructures using state-of-the-art dry vapor-based techniques. The proposed concept realized with biocompatible materials in a simplified design that delivers multi-stimuli sensitivity high...

Background: Nailfold video capillaroscopy (NVC) and angiographic optical coherence tomography (OCTA) have potential in diagnosing psoriatic arthritis (PsA) differentiating it from psoriasis vulgaris (PsO) hand osteoarthritis (OA). Objectives: To assess the diagnostic properties of NVC OCTA patients with PsA compared to PsO OA based on nailfold capillary patterns. Methods: Patients distal interp...

BACKGROUND There is a functional decline of endothelial- dependent vasodilatation in the aging process. The aims of this study were to investigate if various microcirculatory parameters could correlate to anthropometrical variables, oxidative stress and inflammatory biomarkers in successful aging and compare the results to young healthy controls. METHODS Healthy elderly women (HE, 74.0 ± 8.7 ...

BACKGROUND Neurovascular compression (NVC) in the posterior fossa is characterized by complex, three-dimensional (3D) neurovascular relationships at the root entry zones (REZ) and other parts of cranial nerves, resulting in syndromes such as trigeminal neuralgia (TN), hemifacial spasm, vertigo and glossopharyngeal neuralgia. Microvascular decompression (MVD) requires microsurgical experience an...

We explore responsive properties of hollow multilayer shells of tannic acid assembled with a range of neutral polymers, poly(N-vinylpyrrolidone) (PVPON), poly(N-vinylcaprolactam) (PVCL) or poly(N-isopropylacrylamide) (PNIPAM). We found that properties of the nanoscale shells fabricated through hydrogen-bonded layer-by-layer (LbL) assembly can be tuned changing the interaction strength of a neut...
