Summary: This study introduces a new method for isolating and growing single cells from patients' metastatic ascites to establish 3D cultures referred to as sMOCS. By using single cell RNA sequencing, researchers were able to define the cellular composition of metastatic ascites and reproduce features of the original metastasis that cannot be observed in traditional 2D culture. This method provides a powerful tool for precision oncology in ovarian cancer by enriching informative cell subpopulations and analyzing their diversity at the functional and molecular level.

Summary: This study investigated the relationship between filler morphology and pavement properties using morphological analysis and active adhesion test. Results show a close negative linear relationship between filler roundness and adhesion properties. It is recommended that the angularity of mineral filler should be less than 0.895 and the roundness should be less than 0.515 to ensure satisfactory active adhesion between aggregates and bitumen materials.

Summary: To improve the application of stem cell therapy, the authors used upconversion nanoparticles (UCNPs) as contrast agents to track human umbilical cord mesenchymal stem cells (HUCMSCs). The data showed that incubation of UCNPs allowed HUCMSCs to maintain their viability and differentiation ability, with smaller sized UCNPs demonstrating higher uptake capability. This study will contribute to the future engineering of stem cell applications using UCNPs.

Summary: This study demonstrated that 21 days of PLX3397 treatment significantly reduced microglial cells, and MSCs transplantation decreased the number of astrocytes while increasing the population of oligodendrocytes, thereby promoting remyelination. Additionally, the results showed that PLX and MSC treatment elevated levels of remyelination in the corpus callosum of the cuprizone model of MS, indicating a potential therapeutic strategy for MS.

Summary: This study investigated the effects of surfactant-free and surfactant-treated nanoparticles on cell viability and physiology. The results showed that the nanoparticles could scavenge reactive oxygen species and promote cell proliferation and adipogenic differentiation. However, the surfactant-treated nanoparticles exhibited higher cytotoxicity than the surfactant-free nanoparticles after long-term treatment.

Summary: This study assessed the effect of human MSC derived conditioned media on human cancer cell lines, identifying pro-carcinogenic and anti-carcinogenic molecules and effector pathways associated with different MSC types. The use of MSC-CM with pro-carcinogenic effect should be restricted in cancer patients regardless of the application nature.

Summary: Micro-fabrication and nano-fabrication provide useful methods for addressing biological questions by mimicking physiological microenvironments. Two-dimensional patterns and three-dimensional scaffolds, obtained through techniques like lithography and direct laser writing, can shape hydrogels, synthetic polymers, and biologically derived materials for (single) cell culture. Micro-scaffolds mimicking cell niches have applications in stem cell renewal, differentiation, and lineage specification, as well as studying single cells in basic cell biology.

Summary: In this study, a novel xenobiotic-free, serum-free, antibiotic-free, two-step process was developed to treat unilateral limbal stem cell (LSC) deficiency. Cultivated autologous limbal epithelial cells (CALEC) were generated from limbal biopsies and expanded onto human amniotic membrane with rigorous quality control. The clinical trial showed preliminary feasibility and safety of CALEC transplants in patients with unilateral LSC deficiency, leading to a second phase of recruitment to collect longer term safety and efficacy data.

Summary: We report a technique for the spontaneous gathering of oxygen vacancies at strain-relaxed crack walls using flexoelectricity. Enhanced electronic conductance and a switchable diode-like feature were observed at the crack walls. The diffusivity of mobile defects in crack walls was determined to be 1.4 x 10-16 cm2/s, consistent with oxygen vacancy kinetics.

Summary: To accurately predict therapeutic responses in pancreatic and ampullary cancers, researchers have developed a low-volume screening assay and an automated alignment algorithm. By comparing the oligoclonal growth response with validated markers of response, subclonal populations and their relationship with treatment sensitivity were identified. This study is of great significance for utilizing cancer organoid models as biomarkers and advancing novel therapeutic development across different cancer types.

Summary: We have achieved the conformal growth of sp2-hybridized few-layer h-BN on an array of Si-based nanotrenches using pulsed-mode MOCVD method. X-ray absorption fine structure spectroscopy and density functional theory calculations reveal that B-O bonds formed on the noncatalytic SiO2 surface serve as nucleation sites for the subsequent formation of mixed sp2- and sp3-hybridized BON2 and BN3. This allows for the conformal growth of few-layer sp2-hybridized h-BN with excellent step coverage, which can be used for advanced three-dimensional Si-based nanoscale architectures.

Summary: Topological textures of ferroelectric polarizations have potential applications in future information technology. However, energy losses and deviations from stability can affect the symmetry and shape of these textures. In this study, we investigated the domain structure of bismuth tungsten oxide thin films grown on SrTiO3 substrates using advanced microscopy techniques. We discovered a hidden phase with a different polarization orientation that promotes the formation of flux closure domains, bringing us one step closer to an isotropic two-dimensional polar material.

Summary: We propose a method using sodium molybdate liquid alloys to control atomic defects at grain boundaries of monolayer MoS2. The Mo-rich environment in the alloys leads to the formation of Mo-polar 5|7 defects with a yield exceeding 95%. The photoluminescence (PL) intensity of VLS-grown polycrystalline MoS(2) films is enhanced due to the suppression of nonradiative recombination of charged excitons with donor-type defects of adsorbed Na elements.

Summary: In this study, a method to achieve outstanding thermal stability of converse piezoelectric constant in lead-free potassium sodium niobate (KNN)-based ceramics is proposed. The relationship between grain size and polar configuration is demonstrated, and improved thermal stability in fine grains is suggested. The thermal stability is realized in a device by successfully demonstrating the temperature dependence of piezoelectricity, making it possible to apply the lead-free piezoelectric ceramics as piezoelectric devices with high thermal stability.

Summary: When foreign cations are doped into ABO(3)-type perovskite oxides, they usually replace A or B sites depending on their ionic size. This study uncovers the presence of indium dopants occupying square-planar interstices and charge-compensating Ba vacancies at grain boundaries in polycrystalline BaTiO3. This chemical heterogeneity inhibits grain-boundary migration and enables the attainment of fine-grain microstructures with unprecedented dielectric properties.
