Summary: S-palmitoylation is a lipid modification that plays a role in neuronal development and neurodegenerative diseases. In this study, two methods were used to identify S-palmitoylated proteins and sites during neuronal differentiation. A subset of high-confidence S-palmitoylated proteins were identified, suggesting an important role for S-palmitoylation in neuronal differentiation.

Summary: This study investigates the effects of MMA on human neuroblastoma cells and finds that MMA affects glucose consumption and respiratory parameters in both undifferentiated and differentiated cells. Differentiated cells show slightly higher vulnerability to respiratory perturbations by MMA, with impairments appearing in later stages of differentiation. MMA downregulates the transcriptional profile of mature neuronal markers ENO2 and SYP, highlighting important changes during neuronal maturation that could contribute to the neurological clinical symptoms in newborns.

Summary: Research has found that silver nanoparticles with a diameter of 10 nm can inhibit retinoic acid-induced neuronal differentiation. This inhibitory effect may be achieved through the oxidative stress pathway, induction of mitochondrial ROS production, and decreased expression of mitochondrial fusion-related genes.

Summary: In this study, neuroblastoma cells were differentiated into a neuronal-like phenotype and the expression and functionality of acid-sensing ion channels were investigated. It was found that retinoic acid-treated neuroblastoma expressed predominantly the acid-sensing ion channel 1a, which plays important roles in synaptic plasticity, neurodegeneration, and pain perception. This model system can be used for studying the effects of different ligands on native acid-sensing ion channels.

Summary: The neuroblastoma cell line SH-SY5Y is a versatile tool for studying gene expression and differentiation. DNA topoisomerase IIB (TOP2B) plays an important role in regulating the phenotype of these cells, promoting the expression of neural-like characteristics and suppressing the mesenchymal transcription program.

Summary: Tris(2,3-dibromopropyl)isocyanurate (TDBP-TAZTO or TBC) is a widely used hexabromated flame retardant in the production of synthetic compounds. High concentrations of TDBP-TAZTO have been found in the environment, and it can accumulate in the gut and brain of fish by crossing the blood-brain barrier. The study showed that TDBP-TAZTO may affect the expression and activity of CYP1A1 enzyme, AhR, and TUBB3 during the differentiation of SH-SY5Y cells.

Summary: Usnic acid is a common metabolite of lichens with various pharmacological properties. However, its poor solubility and hepatotoxicity limit its use in therapy. In this study, polymeric micelles were developed to improve the solubility and stability of usnic acid, and it was found that the micelles exhibited inhibitory action on neuroblastoma cell migration.

Summary: This study investigated the impact of transient heat shock on the nuclear and cytoplasmic stiffness of SH-SY5Y neuroblastoma cells, as well as the expression of beta-tubulin isotypes. The results showed that heat-exposed cells exhibited increased cytoplasmic stiffness and upregulated expression of beta-II tubulin. Depletion of beta-II tubulin dampened the increase in cytoplasmic stiffness and hindered the differentiation process. This highlights the role of beta-II tubulin as a biomarker for cellular stiffness.

Summary: In this study, we performed a bioinformatics analysis to better understand the possible role of Tau in regulation of chromatin compaction and gene expression. Our findings suggest that Tau depletion leads to deregulation of transcripts involved in the polycomb repressive complex 2, leading to decreased levels of core components of the complex and lower histone 3 trimethylation. These changes are associated with increased senescence induction in Tau-deficient cells.

Summary: This study investigates the mechanism of polarization reversal in yttrium-doped HfO2 by studying the switching behavior in epitaxial and polycrystalline thin film capacitors. It is found that the film microstructure affects the nucleation process, and under external fields approaching the activation field value, the switching kinetics can be described by both nucleation limited switching and the Kolmogorov-Avrami-Ishibashi models.

Summary: Strain engineering is an effective method to control the physical properties of materials, leading to improved performance of devices. In this study, we investigate the transport behavior of two-dimensional MoS2 junctions under mechanical stress induced by an atomic force microscope tip. We find that the junction resistance can be reversibly tuned by altering the tip-induced force. Analysis shows that the strain and strain gradient induced by the tip have combined effects on the energy barrier height and profile. Additionally, we demonstrate that the tip-generated flexoelectric effect enhances the photovoltaic effect in the MoS2 junctions.

Summary: This study investigates the effect of side branches on fractional flow reserve (FFR) estimation. The results show that side branches decrease the total resistance of the vessel tree, leading to a higher inlet flowrate. Side branches located downstream of stenosis result in lower FFR values.

Summary: This study evaluates the upper airway flow characteristics and anatomical features in patients with OSA, and finds that AHI alone is not sufficient to determine the severity of OSA. The degree of airway narrowing is associated with airway collapse. The relative contribution of anatomical and non-anatomical causes to OSA severity can vary between patients.

Summary: In this study, a finite element (FE)-based machine learning model was developed to predict the mechanical properties of bioglass (BG)-collagen (COL) composite hydrogels. Microstructural images with randomly distributed BG particles were created and FE simulations were performed to calculate the mechanical properties. A convolutional neural network regression model was trained and tested using the microstructural images and calculated properties. The results showed that the model effectively predicted the mechanical properties of the composite hydrogels.

Summary: Piezoresponse force microscopy (PFM) is used to investigate the electromechanical behavior of the head-to-head (H-H) and tail-to-tail (T-T) domain walls on the non-polar surfaces of three uniaxial ferroelectric materials. It is found that the crystal at the H-H and T-T domain walls exhibit an out-of-plane deformation even in the absence of the out-of-plane polarization component due to a specific form of the piezoelectric tensor. The dominant contribution comes from the counteracting shear strains on both sides of the domain walls, regardless of the materials' symmetry.

Summary: Ferroelectric domain walls usually have enhanced electrical conductivity, but in lead germanate, head-to-head and tail-to-tail walls are electrically insulating. Recent studies suggest that this is because polar divergence is obviated by domain bifurcation and suspected local dipolar rotation. A study using tomographic piezoresponse force microscopy on triglycine sulfate confirms that mutual domain bifurcation and suspected local dipolar rotation are not unique to lead germanate and may be widely present in other uniaxial ferroelectrics.

Summary: This study quantified the three-dimensional reaction force and moment induced by three different maxillary segmental distalizers (MSDs) on canine and molar teeth. The results showed that the JVBarre (JVB) had less influence on extrusion force, tipping, and rotational moment on the canine compared to the other two CM3D distalizers. However, JVB induced a larger influence on extrusion force, tipping, and rotational moment on the molar due to the change in hook location.

Summary: In this study, the decoration of two-dimensional (2D) materials with MAPbI3 nanoparticles is shown to enhance their visible light photoresponse. The approach was demonstrated using 2D SnS2, which has limited absorption in the visible range. Field-effect transistors based on the decorated SnS2 showed increased photoresponse throughout the visible spectrum. The decorated devices exhibited stable and reproducible photoswitching behavior.

Summary: The study used computer simulation to evaluate the biomechanical events after a soccer ball collision with the eye. It found that the impact generated a pressure wave that caused injuries to the eye and retina. The injuries caused by soccer ball impact are mainly due to linear force, resulting in a more localized injury profile and lower retinal hemorrhage incidence compared with abusive head trauma.
