Fluorescent superparamagnetic magnetite-silica nanocomposites as carriers of a platinum diimine complex for photodynamic therapy.

Novel fluorescent superparamagnetic nanocomposites have been fabricated by introduction of the coumarin group on the surface of amine-functionalized magnetite-silica nanocomposites, and characterized by X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, fluorescence spectra, dynamic light scattering and vibrating sample magnetometer techniques. The nanocomposites were employed as delivery vehicles of a photoactive platinum diimine complex. The cellular uptake and photocytotoxicity of the photosensitizer-loaded nanocomposites in HeLa cells (human cervical cancer line) or HL-7702 cells (human liver cell line) have been studied by fluorescence spectra and cell viability assay, respectively.

Rapid detection of corn moisture content based on improved ICEEMDAN algorithm combined with TCN-BiGRU model.

Rapid detection of corn moisture content(MC) during maturity is of great significance for field cultivation, mechanical harvesting, storage, and transportation management. However, cumbersome operation, time-consuming and labor-intensive operation were the bottleneck in the traditional drying process and dielectric parameter method. Thus, to overcome the above problems, a rapid detection method for corn MC based on improved complete ensemble empirical mode decomposition with adaptive noise (ICEEMDAN) combined with temporal convolutional network-bidirectional gated recurrent unit (TCN-BiGRU) model.

ST2L promotes VEGFA-mediated angiogenesis in gastric cancer by activating TRAF6/PI3K/Akt/NF-κB pathway via IL-33.

Suppression of Tumorigenicity 2 (ST2) is a member of the interleukin-1 receptor/ Toll-like receptor superfamily, and its specific ligand is Interleukin-33 (IL-33). IL-33/ ST2 signaling has been implicated in numerous inflammatory and allergic diseases, as well as in promoting malignant behavior of tumor cells and angiogenesis. However, the precise role of ST2 in gastric cancer angiogenesis remains incompletely elucidated.

Single-pixel phase imaging via a complex-valued Zernike basis.

Single-pixel phase imaging (SPPI) utilizes a single-pixel detector combined with interferometry to capture phase information of an unknown field. However, to reconstruct an M × N image, normally M × N modulations and detections are required, leading to a long imaging time for SPPI. Here, a complex-valued Zernike basis SPPI (Zernike-SPPI) is proposed to achieve phase reconstruction at as high quality as possible with a very low sampling ratio.

A Liquid Band-Aid with Mesenchymal Stem Cell-Derived Exosomes for Wound Healing in Mice.

Introduction/objective: This study aimed to examine the effect of a human umbilical cord mesenchymal stem cell-derived exosome (hUC-MSC-Exo) liquid band-aid on wound healing in mice.

Methods: hUC-MSC-Exos were prepared from the supernatant via ion exchange chromatography. The composition ratio of the chitosan liquid band-aid was optimized to form a film and encapsulate hUC-MSC-Exo.

Flexible and robust cell type annotation for highly multiplexed tissue images.

Identifying cell types in highly multiplexed images is essential for understanding tissue spatial organization. Current cell type annotation methods often rely on extensive reference images and manual adjustments. In this work, we present a tool, Robust Image-Based Cell Annotator (RIBCA), that enables accurate, automated, unbiased, and fine-grained cell type annotation for images with a wide range of antibody panels, without requiring additional model training or human intervention.

Preparation and Performance of Leather-Finished Plywood.

In order to achieve batch production, we propose a simple and fast method to prepare leather-finished plywood. In this study, ethylene-vinyl acetate was selected as the intermediate layer to prepare EVA/polyurethane (PU) leather composites. ESEM, tensile property test and compressive property test were used to characterize the microstructure and physical-mechanical properties of the composites.

The jacktree genome and population genomics provides insights for the mechanisms of the germination obstacle and the conservation of endangered ornamental plants.

Hu represents the first woody genus described by Chinese botanists, with all species classified as endangered ornamental plants endemic to China. Their characteristic spindle-shaped fruits confer high ornamental value to the plants, making them favored in gardens and parks. Nevertheless, the fruits likely pose a germination obstacle, contributing to the endangered status of this lineage.

Duck CD40L as an adjuvant enhances systemic immune responses of avian flavivirus DNA vaccine.

Under the dual pressure of emerging zoonoses and the difficulty in eliminating conventional zoonoses, the strategic management of bird diseases through vaccination represents a highly efficacious approach to disrupting the transmission of zoonotic pathogens to humans. Immunization with a DNA vaccine yielded limited protection against avian pathogen infection. To improve its immunogenicity, the extracellular domain of duck-derived CD40L (designated as dusCD40L) was employed as a bio-adjuvant.

IL-6 Released from Hepatic Stellate Cells Promotes Glycolysis and Migration of HCC Through the JAK1/vWF/TGFB1 Axis.

Purpose: The crosstalk between hepatocellular carcinoma (HCC) cells and hepatic stellate cells (HSCs) is one of the important mechanisms of liver cancer metastasis. The relationship between liver cancer metastasis and glycolysis has been extensively studied recently. However, the role of von Willebrand factor (vWF) mediated glycolysis mechanism in liver cancer metastasis is currently unknown.

Practical NIR Assay Derived from Cyanine to Evaluate Intracellular HS in Living Cell Imaging.

To monitor the biological function of HS in real time, this investigation demonstrated the design and synthesis of a novel fluorescent probe integrated with cyanine and 2,4-dinitrophenol for the qualitative and quantitative detection of HS. An NIR sensitive sensor (FS-HS-1) was provided with a straightforward process.

has a long history of cultivation in Asia and is widely used in food production for its unique aroma, which has important cultural and economic values. It is rich in flavonoids with diverse pharmacological properties, such as antioxidant, anti-tumor, and anti-lipid activities. However, little is known regarding the effects of flavonoid extract (OFFE) on adipogenesis and pre-adipocyte transdifferentiation.

OTUB1/NDUFS2 axis promotes pancreatic tumorigenesis through protecting against mitochondrial cell death.

Pancreatic cancer is one of the most fatal cancers in the world. A growing number of studies have begun to demonstrate that mitochondria play a key role in tumorigenesis. Our previous study reveals that NDUFS2 (NADH: ubiquinone oxidoreductase core subunit S2), a core subunit of the mitochondrial respiratory chain complex I, is upregulated in Pancreatic adenocarcinoma (PAAD).

Analysis of alterations in serum vitamins and correlations with gut microbiome, microbial metabolomics in patients with sepsis.

Background: Vitamins are essential micronutrients that play key roles in many biological pathways associated with sepsis. The gut microbiome plays a pivotal role in the progression of sepsis and may contribute to the onset of multi-organ dysfunction syndrome (MODS). The aim of this study was to investigate the changes in serum vitamins, and their correlation with intestinal flora and metabolomic profiles in patients with sepsis.

A 3D stacked corrugated pore structure composed of CoNiO and polyaniline within the tracheids of wood-derived carbon for high-performance asymmetric supercapacitors.

A novel 3D stacked corrugated pore structure of polyaniline (PANI)/CoNiO@activated wood-derived carbon (AWC) has been successfully constructed to prepare high-performance electrode materials for supercapacitors. AWC functions as a supporting framework that provides ample attachment sites for the loaded active materials. The CoNiO nanowire substrate, consisting of 3D stacked pores, not only serves as a template for subsequent PANI loading, but also acts as an effective buffer to mitigate the volume expansion of the PANI during ionic intercalation.
