Although stem cell-derived extracellular vesicles (EVs) have been shown to facilitate regeneration of injured tissue, there is no report that evaluates the immune-modulating effect EVs on Th2-mediated inflammation. In this study, we evaluated immunomodulatory effects adipose cells (ASCs)-derived inflammation induced by Aspergillus protease antigen in lung epithelial cells. The were isolated from supernatant ASCs and diameters measured using dynamic light scattering. mice primary mouse cell...
Objective The purpose of this study was to analyze computed tomography (CT) and magnetic resonance (MR) images evaluate the maximum standardized uptake value (SUV max) positron emission (PET)/CT parameters between sinonasal non-Hodgkin's lymphoma (NHL) squamous cell carcinoma (SCC), knowing imaging features that distinguish NHL from SCC. Study Design Case series with chart review. Setting University tertiary care facility. Subjects Methods We analyzed on CT, MR imaging, PET/CT 78 patients...
Grid-connected inverter (GCI) plays a crucial role in facilitating stable and efficient power delivery, especially under severe complex grid conditions. Harmonic distortions imbalance of the voltages may degrade grid-injected current quality. Moreover, inductive-capacitance (LC) impedance frequency fluctuation also control performance or stability. In order to overcome such an issue, this study presents frequency-adaptive strategy GCI based on incomplete state observation When LC exists, it...
In this study, microscopic aggregates of copper oxide (CuO) nanoparticles were visualized in porous media for the first time. Two-dimensional visualization results showed that CuO formed regardless flow velocity. The demonstrated velocity determined density and location aggregate deposition media. lower velocity, greater number deposited, larger area deposition—that is, it was not limited to pore neck. Transport also evaluated by comparing breakthrough curves at three different velocities....
Although mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) are as effective MSCs in the suppression of allergic airway inflammation, few studies have evaluated immunomodulatory capacity MSC-derived EVs patients with asthma. Thus, we assessed effects adipose (ASC)-derived on cytokine expression and regulatory T cells (Tregs) peripheral blood mononuclear (PBMCs) asthmatic patients. PBMCs (1 × 106 cells/mL) were isolated from patient healthy controls co-cultured 1 μg/mL...
Synthesis of polyolefin (PO)-based block copolymers is immense research interest. In this work, we report a strategy for the construction polystyrene (PS)-block-PO-block-PS, useful thermoplastic elastomer, directly from olefin and styrene monomers. Multinuclear zinc species Et[Zn(CH2)6]aZnEt were prepared through successive additions BH3 Et2Zn to 1,5-hexadiene. Poly(ethylene-co-propylene) chains biaxially grown −(CH2)6– units in via "coordinative chain transfer polymerization (CCTP)" using...
Purpose: To examine correlations among rating scales and findings suggestive of tracheal aspiration pharyngeal residue between fiberoptic endoscopic evaluation swallowing (FEES) videofluoroscopic study (VFSS) in dysphagia patients. Materials Methods:We studied patients referred to our hospital for assessment.Three raters judged the severity laryngeal penetration or FEES VFSS.The applied Penetration-Aspiration Scale (PAS) pixel-based circumscribed area ratio Yale Pharyngeal Residue Severity...
Drug delivery for the treatment of neurological disorders has long been considered complex due to difficulties in ensuring drug targeting on a specific site damaged neural tissues and its prolonged release. A syringe-injectable polymeric hydrogel with mechanical moduli matching those brain can provide solution deliver drugs region through intracranial injections minimally invasive manner. In this study, an injectable therapeutic antioxidant pomegranate polyphenols, punicalagin, is reported...
The nanosized vesicles secreted from various cell types into the surrounding extracellular space are called (EVs). Although mesenchymal stem cell-derived EVs known to have immunomodulatory effects in asthmatic mice, role of identified pulmonary genes suppression allergic airway inflammation remains be elucidated. Moreover, major responsible for immune regulation diseases not been well documented. This study aims evaluate secretoglobin family 1C member 1 (SCGB1C1) on mouse models. C57BL/6...
A polydiacetylene-based colorimetric sensor was devised to detect malondialdehyde as a food spoilage indicator.
A pair of different diketopyrrolopyrrole-based conjugated polymers (CPs) were designed and synthesized to investigate the effect chain conformation on their molecular assembly. Conformation management was achieved by incorporation linkers during polymerization. Through use computational calculations UV-vis absorption measurements, resulting CPs (PDPP-T PDPP-BT) found exhibit partly modulated geometry. Grazing incident X-ray diffraction experiments with a two-dimensional detector revealed...
A practical and simple method for the preparation of ABA-type olefin triblock copolymers, e.g., PE-b-poly(ethylene-co-propylene)-b-PE, has been described. The performance so-called "coordinative chain transfer polymerization" (CCTP) by sequential feed ethylene ethylene/propylene mixed gas generated a Zn-bound diblock copolymer (i.e., (PE-b-poly(ethylene-co-propylene)yl)2Zn). Treatment with lauroyl peroxide (CH3(CH2)10C(O)O-OC(O)(CH2)10CH3) led to C(sp3)–C(sp3) coupling reaction between two...
