At present, there is no clear consensus on the impact of carbohydrate feeds on bee colony health, and comprehensive research and evaluation in this context is lacking. To comprehensively and objectively examine the health status of honeybees after consuming those carbohydrates from multiple perspectives, experimental techniques, including high-throughput sequencing of the transcriptome, proboscis extension reflex (PER), and measuring bee growth parameters were employed. This study showed that compared with honey, feeding high fructose syrup (HFS) resulted in a decrease in the survival rate and body weight of bees, while sucrose decreased the learning and memory ability of bees.

O-acetylserine (thiol) lyase is a pivotal enzyme in plant cysteine biosynthesis, which is crucial for promoting plant growth, development, and resisting abiotic stress. However, the related studies on the potato OASTL gene family (StOASTL) have not been reported. In the present study, we identified 11 members of the StOASTL gene family, conducting a thorough analysis encompassing chromosome distribution, protein physicochemical properties, gene structure, protein-conserved motifs, and gene replication events.

Acetic acid bacteria (AAB) play a pivotal role in the food fermentation industry, especially in vinegar production, due to their ability to partially oxidize alcohols to acetic acid. However, economic bioproduction using AAB is challenged by harsh environments during acetic acid fermentation, among which initial ethanol pressure, subsequent acetic acid pressure, and consistently high temperatures are common experiences. Understanding the stress-responsive mechanisms is essential to developing robust AAB strains.

Unlabelled: It is well known that gut microbial imbalance is a potential factor for the occurrence and development of diabetes mellitus (DM) and its complications. Moreover, the heart and gut microbiota can regulate each other through the gut-metabolite-heart axis. In this study, metagenomics, metabolomics, and transcriptomics were chosen to sequence the changes in gut microbiota, serum metabolite levels, and differentially expressed genes (DEGs) in leptin receptor-deficient db/db mice and analyze the correlation between serum metabolites and gut microbiota or DEGs.

Both oat β-glucans (OGs) and their hydrolyzed counterparts, oat β-gluco-oligosaccharides (OGOs), are dietary fibers indigestible by humans. They serve as substrates for the colonic intestinal flora, exhibiting potential prebiotic properties. This study, through in vitro digestion simulation, found that OGs and OGOs are not degraded and can safely pass through the upper digestive tract to reach the colon.

Obesity plays a crucial role in the development and progression of type 2 diabetes mellitus (T2DM) by causing excessive release of free fatty acid from adipose tissue, which in turn leads to systemic infiltration of macrophages. In individuals with T2DM, the infiltration of macrophages into pancreatic islets results in islet inflammation that impairs beta cell function, as evidenced by increased apoptosis and decreased glucose-stimulated insulin secretion. The present study aimed to investigate the effects of non-lethal sonodynamic therapy (NL-SDT) on bone marrow-derived macrophages (BMDMs) exposed to high glucose and palmitic acid (HG/PA).

This review article is focused on the development and application of two types of emerging two-dimensional (2D) materials, namely MXenes and MBenes, in the field of gas detection. Owing to its excellent electrical conductivity, specific surface area, and tunable surface functionality, MXenes have demonstrated high sensitivity and rapid response in detecting a variety of gases, such as volatile organic compounds (VOCs), nitrogen dioxide (NO), and ammonia (NH). MBenes are relatively newly discovered materials with excellent electronic stability and gas adsorption capabilities.

Article Synopsis
  • Xanthan gum (XG) is a valuable bacterial exopolysaccharide used in many industries, but low-molecular-weight xanthan gum (LXG) has better properties and applications, though existing production methods are limited.
  • This study presents a novel fermentation system to produce LXG efficiently, using a specific bacterium (Microbacterium sp. XT11) to enhance enzyme activity and optimizing conditions with bean sprout juice as a nitrogen source.
  • The resulting LXG had a low molecular weight, beneficial sugar composition, and demonstrated bioactive properties, indicating its potential as a functional ingredient for promoting intestinal health in foods and supplements.

Plant diseases caused by microbial pathogens pose a severe threat to global food security. Although genetic modifications can improve plant resistance; however, environmentally sustainable strategies are needed to manage plant diseases. Nano-enabled immunomodulation involves using engineered nanomaterials (ENMs) to modulate the innate immune system of plants and enhance their resilience against pathogens.

Accelerated MRI protocols routinely involve a predefined sampling pattern that undersamples the k-space. Finding an optimal pattern can enhance the reconstruction quality, however this optimization is a challenging task. To address this challenge, we introduce a novel deep learning framework, AutoSamp, based on variational information maximization that enables joint optimization of sampling pattern and reconstruction of MRI scans.

  • - The study aimed to verify the pathogenicity of uncertain genetic variants in newborns utilizing mass spectrometry and analysis, involving 3,071 participants across 35 centers.
  • - Results indicated that 68.15% of subjects carried variants of uncertain significance (VUS), with those having pathogenic variants showing significantly higher levels of specific metabolites compared to non-variant groups.
  • - The findings suggest that elevated metabolic biomarkers in VUS cases could indicate a likely pathogenic status, implying that mass spectrometry and analysis are promising methods for studying these genetic variants.

Owing to the impact of the effluent C/N from the secondary structures of urban domestic wastewater treatment plants, the denitrification efficiency in constructed wetlands (CWs) is not satisfactory, limiting their widespread application in the deep treatment of urban domestic wastewater. To address this issue, we constructed enhanced CWs and conducted orthogonal experiments to investigate the effects of different factors (C/N, fillers, and plants) on the removal of conventional pollutants and the reduction of greenhouse gas (GHG) emission. The experimental results indicated that a C/N of 8, manganese sand, and calamus achieved the best denitrification efficiencies with removal efficiencies of 85.

Antibiotic residue and bacterial resistance induced by antibiotic abuse have seriously threatened food safety and human healthiness. Thus, the development and application of safe, high-efficiency, and environmentally friendly antibiotic alternatives are urgently necessary. Apart from antitumor, antivirus, anti-inflammatory, gut microbiota regulation, immunity improvement, and growth promotion activities, polysaccharides also have antibacterial activity, but such activity is relatively low, which cannot satisfy the requirements of food preservation, clinical sterilization, livestock feeding, and agricultural cultivation.

The presence of asymptomatic carriers, often unrecognized as infectious disease vectors, complicates epidemic management, particularly when inter-community migrations are involved. We introduced a SAIR (susceptible-asymptomatic-infected-recovered) infectious disease model within a network framework to explore the dynamics of disease transmission amid asymptomatic carriers. This model facilitated an in-depth analysis of outbreak control strategies in scenarios with active community migrations.
