The diterpene andrographolide, a nature-derived product, exerts a wide range of pharmacological effects, including anti-inflammatory, antiviral, immunostimulatory, and anticancer activities, due to its ability to target multiple pathways. In this study, some andrographolide derivatives of an enlarged decalin structure with a seven-membered ring or an isoxazole-fused decalin structure were designed, synthesized, and evaluated for their activity against cancer cell growth and angiogenesis. Among them, compound AGW-11 (designated as compound 8) showed potent and broad-spectrum anticancer activity and anti-angiogenic activity in vitro.

Aspect sentiment classification (ASC) is a subtask of Aspect-based sentiment analysis (ABSA), and its goal is to predict the sentiment polarity corresponding to specific aspect word within a sentence. Existing ABSA methods have achieved impressive predictive performance by not only leveraging attention mechanism to capture semantic association information within sentences, but also employing graph convolutional network (GCN) to exploit the syntactic structure information of dependency and constituency trees. However, these methods still have two main shortcomings: (1) they overlook the utilization of local sentiment features in the constituency tree, focusing only on global sentiment features; and (2) they fail to comprehensively utilize the syntactic information from both dependency and constituency trees.

Background: Coumarins are toxic phytochemicals found in a variety of plants and are known to limit microbial degradation and interfere with nutrient cycling. While the degradation of coumarins by fungi has been studied in an environmental context, little is known about their degradation in the gastrointestinal system of herbivores after ingestion.

Results: In this study, we investigated in vitro fermentation by microbial enrichment, transcriptome sequencing, and high-resolution mass spectrometry to evaluate the ability of rumen anaerobic fungi to degrade coumarins.

Anaerobic gut fungi (AGF) were the last phylum to be identified within the rumen microbiome and account for 7% to 9% of microbial biomass. They produce potent lignocellulases that degrade recalcitrant plant cell walls, and rhizoids that can penetrate the cuticle of plant cells, exposing internal components to other microbiota. Interspecies H transfer between AGF and rumen methanogenic archaea is an essential metabolic process in the rumen that occurs during the reduction of CO to CH by methanogens.

The present study aimed to investigate the impact of Sparassis latifolia polysaccharides (SLPs) on hepatic immune function in cyclophosphamide (CTX)-induced immunocompromised mice. Our findings demonstrated that SLPs effectively suppressed the production of alanine aminotransferase (ALT), aspartate aminotransferase (AST), inflammatory factors, and acute phase proteins, while improving the hepatic oxidative stress state. Additionally, SLPs exerted inhibitory effects on inflammatory cell infiltration within hepatic tissue.

Natural compounds demonstrate unique therapeutic advantages for cancer treatment, primarily through direct tumor suppression or interference with the tumor microenvironment (TME). Glycyrrhizic acid (GL), a bioactive ingredient derived from the medicinal herb Glycyrrhiza uralensis Fisch., and its sapogenin glycyrrhetinic acid (GA), have been recognized for their ability to inhibit angiogenesis and remodel the TME.

The delivery vehicles based on protein-polysaccharide-polyphenol are promising methods to encapsulate bioactive components with the aim of improving their solubility and bioavailability. In this study, we used Flammulina velutipes protein (FVP) and Flammulina velutipes soluble polysaccharides (FVSP) as raw materials and prepared FVP-FVSP and FVP-FVSP-TP composite particles loaded with tea polyphenols (TP), the high internal phase Pickering emulsions stabilized by FVP-FVSP and FVP-FVSP-TP for the delivery of β-carotene (BC) were created. FVP-FVSP-TP has more promise as Pickering emulsion stabilizer than FVP-FVSP because of the smaller particle size, proper contact angle, and lower surface tension.

Feruloyl esterase (FAE) has been extensively studied for its crucial auxiliary effect in the biodegradation of lignocellulose. In this study, a FAE database including 15,293 amino acid sequences was established to gain a better understanding of rumen FAEs through multi-omics analysis. The higher expression level of rumen fungal FAEs over bacterial FAEs suggests that rumen fungi may have more important role in the lignocellulose degradation.

Glycation of ferritin provides a viable approach to enhance its physicochemical and functional properties. However, there is limited research on the interfacial adsorption properties of glycated ferritin-based colloidal particles. Therefore, this study selected recombinant human H-chain ferritin (rHuHF), rHuHF encapsulated with resveratrol (rHuHF-Res), and rHuHF-dextran glycoconjugates loaded with resveratrol (Dex-rHuHF-Res) as emulsifiers to investigate their interfacial adsorption properties.

Second-generation biofuel production, which aims to convert lignocellulose to liquid transportation fuels, could be transformative in worldwide energy portfolios. A bottleneck impeding its large-scale deployment is conversion of the target polysaccharides in lignocellulose to their unit sugars for microbial fermentation to the desired fuels. Cellulose and hemicellulose, the two major polysaccharides in lignocellulose, are complex in nature, and their interactions with pectin and lignin further increase their recalcitrance to depolymerization.

Background: Instead of completely suppressing blood vessels inside tumors, vascular normalization therapy is proposed to normalize and prune the abnormal vasculature in tumor microenvironment (TME) to acquire a normal and stable blood flow and perfusion. The theoretical basis for the use of "blood-activating and stasis-resolving" formulas in Traditional Chinese Medicine to treat cancer is highly consistent with the principle of vascular normalization therapy, suggesting the potential application of these traditional formulas in vascular normalization therapy.

Purpose: To study the underlying mechanisms of a classical "blood-activating and stasis-resolving" formula, Taohong Siwu decoction (TSD), in enhancing the efficacy of chemotherapy for breast cancer treatment.

Article Synopsis
  • The increasing demand for animal products in developing countries is contributing to global warming, with livestock production responsible for 25% of emissions, prompting research into probiotics as a solution to enhance livestock efficiency.
  • In a study, adding 8 × 10 CFU g of Saccharomyces cerevisiae decreased methane emissions and improved nutrient factors, while 20 × 10 CFU g of Bacillus subtilis increased total gas production but did not impact pH.
  • The results suggest that combining these probiotics in specified doses can boost overall fermentation efficiency and mitigate methane emissions in sheep, providing a potential strategy for environmentally friendly livestock production.
