Background: Myofibroblasts constitute a significant component of the tumor microenvironment (TME) and play a pivotal role in the progression of hepatocellular carcinoma (HCC). Integrin α5 (ITGA5) is a crucial regulator in myofibroblasts of malignant tumors. Therefore, the potential of ITGA5 as a novel target for the therapeutic strategy of HCC should be investigated.

Diammonium glycyrrhizinate alleviates iron overload-induced liver injury in mice via regulating the gut-liver axis.

Background: Evidence indicates a close association between iron overload (IO) and the pathogenesis of chronic liver diseases, highlighting the potential for interventions targeted at IO to impede or decelerate the progression of chronic liver diseases. Diammonium glycyrrhizinate (DG), the medicinal form of glycyrrhizic acid, a principal constituent of licorice, has been clinically employed as a hepatoprotective agent; however, its protective effect against IO-induced liver injury and underlying molecular mechanisms remain elusive.

Purpose: The aim of the present study is to investigate the hepatoprotective effect of DG against IO-induced liver injury with a focus on the gut-liver axis.

Efficient generation of broadband photon pairs in shallow-etched lithium niobate nanowaveguides.

We design and fabricate shallow-etched periodically poled lithium niobate waveguides to realize highly efficient broadband spontaneous parametric down-conversion (SPDC) on nanophotonic chips. The shallow-etched waveguide can tolerate the non-uniformities of waveguide width induced by fabrication imperfections, enabling the generation of photon pairs with high count rate and bandwidth. We demonstrate photon-pair generation with a high brightness of 11.

Enhancing Manganese Peroxidase: Innovations in Genetic Modification, Screening Processes, and Sustainable Agricultural Applications.

Manganese peroxidase (MnP), a vital extracellular enzyme for the degradation of lignin and other organic pollutants, has demonstrated immense potential for agricultural and environmental applications, including straw pretreatment, feed fermentation, mycotoxin degradation, and water treatment. However, current research remains in its exploratory phase, with naturally sourced MnP unable to meet industrial-scale demands and no mature commercial enzyme preparations available on the market. This comprehensive review innovatively constructs a framework for MnP research, probing into its molecular conformation and catalytic principles, while providing an overview of the advancements in high-throughput screening and designing strategies.

High-throughput screening and identification of lignin peroxidase based on spore surface display of Bacillus subtilis.

Background: Lignin peroxidase is closely related to agriculture and food as it improves the quality of feedstuffs, facilitates the degradation of lignin in agricultural wastes, and degrades azo dyes that have similar complex structures to lignin. However, the current status of homologous or heterologous expression of lignin peroxidase is unsatisfactory and needs to be modified with the help of immobilization and directed evolution to maximize its potential. Directed evolution technology is an effective strategy for designing and improving enzyme characteristics, and Bacillus subtilis spore surface display technology is an efficient method for preparing immobilized enzymes.

Methods: To investigate this, we employed a multi-omics approach analyzing blood samples from 52 NMOSD patients and 46 healthy controls (HC).

Demand Potential for Agricultural Trade between China and Countries along the "Belt and Road".

International agricultural markets are an important part of the global food resource chain. Tapping into the potential of agricultural trade between China and countries along the "Belt and Road" (B&R) is conducive to safeguarding China's and the world's food security, but there is less literature on the potential of bilateral trade demand. This paper ranks the B&R countries according to the scale of imports and exports, and calculates the elasticity of demand for imports, the elasticity of substitution for exports, and, finally, the potential of elasticity of demand for trade between China and the major B&R countries.

Placental growth factor alleviates hyperglycemia-induced trophoblast pyroptosis by regulating mitophagy.

Introduction: Hyperglycemia is closely related to trophoblast dysfunction during pregnancy and results in suppressed invasion, migration, and pro-inflammatory cell death of trophoblasts. Hyperglycemia is a dependent risk factor for gestational hypertension accompanied by decreased placental growth factor (PLGF), which is important for maternal and fetal development. However, there is currently a lack of evidence to support whether PLGF can alleviate trophoblast cell dysfunction caused by high blood sugar.
