Abstract Agricultural waste is a potentially interesting resource due to the compounds present. In this study, cellulose was extracted from corn stalks (Zea mays) and subsequently converted into cellulose acetate (CA). Before the extraction process, the waste sample was characterized by pH, moisture, ash, protein content, total reducing sugars (TRS), carbohydrates, cellulose, hemicellulose, and lignin. Acid and alkaline hydrolysis were performed with different reagents, concentrations, and extraction times. Sulfuric acid (H₂SO₄) and acetic acid (CH₃COOH) were used in the acid hydrolysis, while sodium hydroxide (NaOH) was used in the alkaline hydrolysis. Three concentrations (0.62, 1.25, 2.5)% and two… More >

Abstract Crop leaf area index (LAI) and biomass are two major biophysical parameters to measure crop growth and health condition. Measuring LAI and biomass in field experiments is a destructive method. Therefore, we focused on the application of unmanned aerial vehicles (UAVs) in agriculture, which is a cost and labor-efficient method. Hence, UAV-captured multispectral images were applied to monitor crop growth, identify plant bio-physical conditions, and so on. In this study, we monitored soybean crops using UAV and field experiments. This experiment was conducted at the MAFES (Mississippi Agricultural and Forestry Experiment Station) Pontotoc Ridge-Flatwoods Branch… More >

Abstract Species of the genus Paenibacillus, especially those from extreme environments that have been reported, are known for producing bioactive compounds with agricultural and biotechnological applications. In this study, we investigated the genomic and biochemical potential of Paenibacillus sp. VCA1 strain isolated from a thermophilic environment. Taxonomic identification was performed using whole genome similarity analysis, TETRA four-nucleotide frequency of occurrence analysis, ANI average nucleotide identity analysis, and gene distance analysis using digital DNA-DNA hybridization (dDDH). Functional analysis of the strain VCA1 was performed by detecting genes, enzymes, and genome subsystems involved in biocontrol and plant growth promotion,… More >

Abstract As ubiquitous environmental contaminants, microplastics (MPs) have garnered global concern due to their persistence, bioaccumulation potential, and multifaceted threats to ecosystem health. These particles threaten terrestrial ecosystems via soil contamination; however, research on their phytotoxicity remains predominantly focused on herbaceous plants. The responses of woody plants to MPs and their interspecific differences are severely unexplored. Here, two important ecological and economical tree species in southern China, Pinus massoniana (P. massoniana) and Schima superba (S. superba), were selected to explore the ecotoxicity effects of polyethylene (PE) and polypropylene (PP) MPs (the two most abundant species in the soil) on… More >

Abstract Objective: The World Health Organization (WHO) grading based on histopathology cannot always accurately predict tumor behavior of meningiomas. To overcome the limitations of the WHO grading, the study aims to propose a novel oxidative stress-based molecular classification for WHO grade 2/3 meningiomas. Methods: Differentially expressed oxidative stress-related genes were analyzed between 86 WHO grade 1 (low grade) meningiomas and 99 grade 2/3 (high grade) meningiomas. An oxidative stress-based molecular classification was developed in high-grade meningiomas through consensus clustering analysis. Immune microenvironment features, responses to immunotherapy and chemotherapy, and targeted drugs were evaluated. Three machine learning… More >

Abstract Distributed data fusion is essential for numerous applications, yet faces significant privacy security challenges. Federated learning (FL), as a distributed machine learning paradigm, offers enhanced data privacy protection and has attracted widespread attention. Consequently, research increasingly focuses on developing more secure FL techniques. However, in real-world scenarios involving malicious entities, the accuracy of FL results is often compromised, particularly due to the threat of collusion between two servers. To address this challenge, this paper proposes an efficient and verifiable data aggregation protocol with enhanced privacy protection. After analyzing attack methods against prior schemes, we implement… More >

Abstract Primary diamines play an important role in the chemical industry, where they are widely used as raw materials for the manufacture of pharmaceuticals and polymers. Currently, primary diamines are mainly derived from petroleum, while harsh or toxic conditions are often needed. Biomass is abundant and renewable , which serves as a promising alternative raw material to produce primary diamines. This review primarily focuses on the synthesis of 2,5-bis(aminomethyl)furan (BAMF), a bio-based diamine with potential as a biomonomer for polyamides and polyureas. Specifically, this review emphasizes the synthesis of BAMF from three biomass-derived alcohols and aldehydes,… More > Graphic Abstract

Abstract Objective: To investigate the usefulness of the descending aortic retrograde flow area to forward flow area (dAO RF) ratio using echocardiography in managing pulmonary blood flow during the perioperative period following Blalock-Thomas-Taussig shunt (BTTS) surgery. Methods: This retrospective study analyzed patient characteristics, surgical procedures, and perioperative courses. The dAO RF ratio was measured upon admission to the pediatric intensive care unit (PICU) and 12, 24, 48, and 72 h post-surgery. Blood pressure, percutaneous oxygen saturation, arterial blood gas values, and lactate levels were measured at the same time as the dAO RF ratio. Results: Seventy-one cases were… More >

Abstract Objectives: Proteasomes, multi-subunit proteases, are key actors of cellular protein catabolism and a number of regulatory processes. The detection of subtle proteasome functioning in tumors may contribute to our understanding of the mechanisms of cancer development. The current study aimed to identify the role of low molecular mass protein 2 (LMP2), a proteasome immune subunit, in the development of mouse colon 26 (C26) adenocarcinoma. Methods: The functions of the LMP2 subunit in tumor development in Balb/c mice were studied using its irreversible inhibitor KZR-504. LMP2 activity was detected by the hydrolysis of the fluorogenic substrate… More >

Abstract The use of agricultural residues in biocomposite production has gained increasing attention, driven by several benefits. Converting agricultural by-products into bio-based materials within a circular economy represents a sustainable strategy to mitigate lignocellulosic waste, reduce reliance on fossil resources, and lower environmental pollution. This approach also creates economic opportunities for rural African communities by generating diverse income sources for workers in collection, processing, and manufacturing. As a result, the integration of agricultural residues into biocomposites production not only addresses environmental concerns but also fosters economic growth and supports rural development. In this review, five biomasses… More > Graphic Abstract
