: This study aimed to investigate the influence of a respiratory mucosa-on-a-chip on the respiratory epithelial differentiation potential of human nasal inferior turbinate-derived stem cells (hNTSCs). : After isolating hNTSCs from five patients, we divided the samples from the patients into the study group with a mucosa-on-a-chip and the control group with conventional differentiation (using conventional differentiation methods). The respiratory epithelial differentiation potential of hNTSCs was analyzed by histology and gene expression.

Aquatic environments are being polluted by microplastics primarily originating from the washing of synthetic textiles. Microfibers (MF), which are microplastics in synthetic fibers, are consistently introduced into the environment with each domestic laundry cycle. To address this issue, we developed a specialized MF capture "barbed filter" (BF) by transforming PET monofilaments of different diameters (0.

Waterborne polyurethane-acrylate (WPUA) grafted with polyurethane was prepared to improve the film-forming ability of hard-type acrylic latex. To balance the film-formation ability and hardness, the WPUA latex was designed with a hard core (polyacrylate) and soft shell (polyurethane). The grafting ratio was controlled through varying the content of 2-hydroxyethyl methacrylate (HEMA) used to cap the ends of the polyurethane prepolymer.

Article Synopsis
  • * After treating the filler, the researchers created composites through melt-mixing and extrusion-injection molding to assess compatibility and migration behavior.
  • * Results showed that using butyl acrylate and maleic anhydride improved filler migration issues while preserving mechanical properties, but too much hydrophobicity from lauric acid decreased compatibility, indicating a balance is needed for effective automotive applications.

The improvement of gel strength and absorption properties through the surface-crosslinking of superabsorbent polymers (SAPs) is essential for sanitary industry applications. We prepared core-SAP via aqueous solution copolymerization, and then surface-crosslinked the core-SAP under various conditions. The structure of the SAP was characterized using Fourier transform infrared (FT-IR) spectroscopy.

Synthetic fibers released during washing are the primary source of microplastic pollution. Hence, research on reducing the release of microplastic fibers during washing has recently attracted considerable attention. As a result of previous studies, there is a difference in the amount of microplastic emission according to various types of fabrics.

With the increasing production of synthetic materials, more microplastic fibers are being generated while washing clothes. Consequently, these particles are increasingly detected in the aquatic environment. Synthetic fibers produced via washing have a relatively high contribution to microplastic pollution.

Microplastics reach the aquatic environment through wastewater. Larger debris is removed in sewage treatment plants, but filters are not explicitly designed to retain sewage sludge's microplastic or terrestrial soils. Therefore, the effective quantification of filtration system to mitigate microplastics is needed.

A facile method to prepare hybrid cellulose acetate nanofibers containing TiO (TiO-CA nanofibers) by emulsion electrospinning technique was developed for the denitrification and filtration of particulate matters (PMs). This work found that hybrid TiO-CA nanofibers mainly contain the anatase form of TiO, contributing to the photodecomposition of NO gas under UV irradiation. The TiO-CA nanofibers also showed an excellent filtration efficiency of 99.

The present study aimed to analyze the compensatory signaling pathways induced by forkhead domain inhibitor‑6 (FDI‑6), which is a forkhead box protein M1 (FOXM1) inhibitor, in ovarian cancer cells and evaluate the effectiveness of simultaneous inhibition of FOXM1 and the compensatory signaling pathway in decreasing the survival of ovarian cancer cells. The present study identified the proteins involved in the compensatory mechanism activated by FDI‑6 in HeyA8 ovarian cancer cells using western blot analysis and a reverse‑phase protein array. In addition, a cell viability assay was performed to determine the effects of FDI‑6 and the compensatory signaling pathway on cancer cell viability.

Purpose: Patients with metastatic melanoma have a poor prognosis and few treatment options are available. We evaluated the anti-tumor activity and safety of nilotinib, a KIT inhibitor, in patients with metastatic melanoma harboring KIT alterations, either mutations or amplifications.

Patients And Methods: This study was open-label, single center, prospective phase II clinical trial.
