Revision total hip arthroplasty with medial wall defect using bone graft with or without porous metal restrictor.

When a severe medial wall defect is present in revision total hip arthroplasty (THA), simple bone grafting (BG) may not be sufficient, and trabecular metal (TM) augmentation is often necessary. We aimed to evaluate whether there were differences in outcomes of revision THA with medial wall defects depending on the use of TM augmentation. Between 2009-2021, 130 patients were classified into two groups: 80 patients undergoing bone grafting (BG group) and 50 patients undergoing both bone grafting and TM augmentation (BG/TM group).

Enhancing barrier properties of cellulose propionate films through the integration of ionic liquid: A study on water pressure resistance.

This study pioneers the production of porous cellulose propionate (CP) films enhanced with tetrabutylammonium styrenesulfonate ([N][SS]), an ionic liquid, to bolster their resistance against water pressure. In contrast to polymer films with ionic liquids that have high moisture permeability, the CP/[N][SS] films exhibit remarkable water resistance even under 8 bar pressure. This is due to the physical cross-linking between the [N] ions and CP's polar groups, limiting CP chain mobility and thus reducing water interaction.

Therefore, this paper focuses on carbon dioxide separation by creating an hydroxyethyl cellulose (HEC)(CHO)*(CHO(OH))/silver tetra fluoroborate (AgBF)/aluminum nitrate (Al(NO)) composite film, demonstrating excellent separation performance with a permeance of 1.0 GPU and a selectivity of 100.

Enhancing CA-based separators with thermo-responsive ionic liquids: A path to eco-friendly membrane production and multifaceted applications.

We synthesized a temperature-responsive ionic liquid, [N][SS], and incorporated it into an environmentally friendly cellulose acetate (CA)-based battery separator. A pore was formed in the battery separator by [N][SS], which pierced a plasticized part due to water pressure. Varying drying temperatures during membrane fabrication revealed that the CA/[N][SS] membrane dried at 50 °C exhibited greater thickness and a smaller average pore size, resulting in an asymmetric internal structure.

Methods: Twenty-four mice were divided randomly into 4 equal groups: [1] the normal group, n = 6; [2] the liver fibrosis (LF) group, n = 6; [3] the LF and IR group, n = 6; and [4] the LF with treatment of rapamycin and IR group; n = 6.

Influence of citric acid concentrations on the porosity and performance of cellulose acetate-based porous membranes: A comprehensive study.

This study investigates the influence of citric acid concentration on the fabrication of porous cellulose acetate (CA) membranes using the Non-Solvent Induced Phase Separation (NIPS) method. A notable aspect is the precise control over membrane properties, particularly pore size and porosity, achieved solely through the adjustment of citric acid concentration, serving as the additive. Higher concentrations of citric acid increase pore size by rendering polymer chains more pliable, whereas lower concentrations lead to smaller, denser pores due to improved dispersion in the CA matrix and altered water interactions during phase separation.

Enhanced porous membrane fabrication using cellulose acetate and citric acid: Improved structural integrity, thermal stability, and gas permeability.

In this study, our primary objective was to enhance the properties of porous membranes by addressing the limitations associated with phase separation. We employed a non-solvent induced phase separation (NIPS) method, utilizing cellulose acetate (CA) in conjunction with citric acid to fabricate these membranes. Citric acid played a dual role: ensuring a uniform pore structure and cross-linking the CA polymer, thereby enhancing its mechanical strength.

Channels formation in cellulose materials by accelerated transport of gas molecules and glycerin.

In this study, a microporous separator was produced using cellulose acetate (CA), which demonstrates heightened thermal stability in comparison to existing materials like polypropylene (PP) or polyethylene (PE). Furthermore, a pliable component was integrated into the CA membrane using glycerin as the plasticizing agent. Subsequently, gas pressure was exerted onto these areas to induce the formation of nano-sized pores.

Blood flow patterns switch VEGFR2 activity through differential S-nitrosylation and S-oxidation.

Vascular endothelial growth factor receptor-2 (VEGFR2) plays a key role in maintaining vascular endothelial homeostasis. Here, we show that blood flows determine activation and inactivation of VEGFR2 through selective cysteine modifications. VEGFR2 activation is regulated by reversible oxidation at Cys residue.

Gas transport into cellulose materials for highly porous structure.

To solve the low thermal stability of polyolefin membranes, our group developed porous polymers using cellulose acetate (CA) material.

Spatial Balance of Photogenerated Charge Carriers in Active Layers of Polymer Solar Cells.

Bulk heterojunction polymer solar cells (PSCs) blended with non-fullerene-type acceptors (NFAs) possess good solar power conversion efficiency and compatibility with flexible electronics, rendering them good candidates for mobile photovoltaic applications. However, their internal absorption performance and mechanism are yet to be fully elucidated because of their complicated interference effect caused by their multilayer device structure. The transfer matrix method (TMM) is ideal for analyzing complex optical electric fields by considering multilayer interference effects.

Glucose Deprivation Induces Cancer Cell Death through Failure of ROS Regulation.

In previous work, we showed that cancer cells do not depend on glycolysis for ATP production, but they do on fatty acid oxidation. However, we found some cancer cells induced cell death after glucose deprivation along with a decrease of ATP production. We investigated the different response of glucose deprivation with two types of cancer cells including glucose insensitive cancer cells (GIC) which do not change ATP levels, and glucose sensitive cancer cells (GSC) which decrease ATP production in 24 h.

Surface of CuO Nanoparticles Modified by -Benzoquinone for N-Selective Membrane.

In this study, CuO nanoparticles and -benzoquinone (-BQ) were added to a polyvinylpyrrolidone (PVP) matrix to increase N/CO selectivity. The added -BQ allowed CuO to be distributed in a uniform size in the PVP/CuO composite membrane and the matrix to be flexible by forming the interaction with PVP. The surface modification of CuO by -BQ and the well-dispersed size affected the increase in the separation performance.
