The synthesis of nanoparticles utilizing green techniques is becoming increasingly important due to its low cost, biocompatibility, high productivity, and eco-friendliness. Herein, the current work focused on the biosynthesis, characterization, and biological applications of zinc oxide nanoparticles (ZnO-NPs) from Anabasis articulata, including antioxidant anticancer and larvicidal properties, as well as modifications to the phytochemical ingredients. Hence, the tannin, phenolic, and flavonoid concentrations of the produced nanoparticle samples were lower than those of the original aqueous extract. When compared to the results of ascorbic acid (12.78 mg/mL), the produced extract of A. articulata and its zinc nanoparticles showed remarkable efficacy as antioxidant agents with IC₅₀ values of 27.48 and 69.53 mg/mL, respectively. A normal lung fibroblast cell line (WI-38) and three tumor cells were used to test the compounds’ anticancer properties. With an IC₅₀ of 21.19 µg/mL, the ZnO-NPs of A. articulata showed the greatest cytotoxicity against HePG-2 cell lines. Additionally, A. articulata zinc nanoparticles showed significant cytotoxicity against MCF-7 and PC3 tumor cell lines, with IC₅₀ values of 30.91 and 49.32 µg/mL. The biogenic ZnO-NPs had LC₅₀ and LC₉₀ values of 13.64 and 26.23 mg/L, respectively, and are very effective against Aedes aegypti larval instar (III). Additionally, the percentages of larval mortality increased from 28.61% at 5 ppm to 84.69% at 25 ppm after 24 h post-treatment. The overall results of this study point to the potential of A. articulata as a substitute biological agent for potential therapeutic/leutic uses in the medical domains and for preventing the proliferation of malarial vector insects.

Kinetoplastids are protozoa that possess a unique organelle called a kinetoplast. These include the parasites Trypanosoma cruzi, T. brucei and related African trypanosomes, and Leishmania spp. These parasites cause a variety of neglected tropical diseases in humans and livestock, with devastating consequences. In the absence of any vaccine, pharmaceutical interventions are the mainstay of control, but these have historically been underfunded, fragmented, and inadequately aligned with the complex zoonotic and ecological realities of the parasites’ transmission dynamics. In this review, the landscape of current and emerging drugs for treating leishmaniasis, Chagas disease, and African trypanosomiasis is critically evaluated across both veterinary and human contexts. It examines the challenges of legacy compounds, the pharmacological shortcomings in multi-host, multi-tropic and multi-stage disease systems, and the gaps in veterinary therapeutics, specifically for African animal trypanosomiasis and canine leishmaniasis but also the animal reservoir of T. cruzi. Emphasis is placed on pharmacokinetic divergence between species, the accompanying risks with the use of off-label human drugs in animals, and the ecological effects of environmental drug exposure. We propose a far-reaching One Health framework for pharmaceutical research and development, promoting dual-indication co-development, ecological pharmacology, regulatory harmonisation, and integrated delivery systems. In this context, we argue that the drug development pipeline must be rationalised as a transdisciplinary and ecologically embedded process, able to interrupt parasite transmission to human, animal, and vector interfaces. Our findings reveal that we can bridge age-old therapeutic gaps, advance towards sustainable control, and eventually eliminate the neglected diseases caused by kinetoplastid protozoan parasites by aligning pharmaceutical innovation with One Health principles. This article aims to promote future research and development of innovative drugs that are sustainable under the One Health framework.

This study aimed to examine whether or not aluminum chloride (AlCl₃)-induced hepatotoxicity might be mitigated using magnetic water (MW) in rats. This study involved 28 adult male rats randomly assigned into the following 4 groups (7 rats/group): normal control (Cnt), MW, AlCl₃, and Al Cl₃ + MW. The Cnt group orally received normal saline, the MW group drank MW ad libitum for 2 months, and the AlCl₃ and AlCl₃ + MW groups were orally administered AlCl₃ (40 mg/kg b.w.) alone or in combination with MW for 2 months, respectively. MW reduced AlCl₃ toxicity as proved at functional, molecular, and structural levels. Functionally, MW reduced serum levels of liver enzymes (ALT, AST, ALP, GGT), while increased total proteins, and albumin. MW also restored redox balance in the liver (lower MDA levels, higher activities of CAT and SOD enzymes, and upregulated expression of NrF2, HO-1, and GST genes. Molecularly, MW downregulated hepatic expression of the epigenetic (HDAC3), inflammatory (IL1β, TNFα, NFκβ), and endoplasmic reticulum stress (XBP1, BIP, CHOP) genes. Structurally, MW enhanced liver histology. With these results, we could conclude that MW has the potential to ameliorate the hepatotoxic effects of AlCl₃ through targeting oxidative stress, inflammation, epigenesis, and endoplasmic reticulum stress.

Silver nanoparticles (AgNPs) are valued for their antimicrobial properties, but conventional synthesis often involves toxic chemicals. Eco-friendly biosynthesis using silver-tolerant microbes from contaminated sites offers a sustainable alternative. This study biosynthesized and characterized AgNPs using a native Bacillus sp. from contaminated soil in the Jazan region, Saudi Arabia, and developed predictive models for optimizing synthesis and antimicrobial activity. AgNPs were synthesized under optimized conditions (1.0 mM AgNO₃, 4.0 mL supernatant, pH 8, 85 °C). Characterization using UV–Vis, SEM, TEM, XRD, and FTIR assessed size, shape, structure, and chemistry. Gaussian and second models evaluated yield and inhibition zones based on AgNP concentration, microorganism type, and MIC. The AgNPs were spherical with diameters of 5–10 nm. The optimal nanoparticle yield occurs when the parameters are at their optimal values; C₀ = 1.0 mM, V₀ = 4.0 mL, pH₀ = 8, T₀ = 85 °C. XRD confirmed their crystalline nature, and FTIR showed biomolecular capping agents for stabilization. The Gaussian model accurately predicted synthesis efficiency, validated by 3D plots matching experimental data. The AgNPs showed strong antimicrobial activity against Gram-positive (Bacillus subtilis) (ATCC6051), Staphylococcus aureus (ATCC12600), Gram-negative bacteria Escherichia coli (ATCC11775) and fungi Candida albicans (ATCC10231); with E. coli having the lowest MIC (1.87 μg/mL). The inhibition zone model closely matched observed data. Biosynthesized AgNPs using silver-tolerant Bacillus sp. demonstrated potent antimicrobial effects and provide a green alternative to chemical synthesis. Integrating modeling optimizes biosynthesis and predicts biological performance, supporting future nanobiotechnology and antimicrobial applications.

Fungal infection in agricultural grains is a global problem, particularly if it is accompanied by mycotoxin production. In this study, the degradation of mycotoxins by laccase and manganese peroxidase was investigated. Aspergillus flavus, Aspergillus fumigatus, and Fusarium graminearum were recorded in infected maize grains. Aflatoxin B1 (AF B1) was detected (from 3.38 to 2.60 ppm) on the infected samples by fungi compared to other detected aflatoxins. Trichothecene (T-2) toxin and deoxynivalenol (DON) were recorded with concentrations ranging from 0.464 to 0.184 ppm and 0.370 to 0.214 ppm, respectively. The addition of laccase and manganese peroxidase to the inoculated medium with A. flavus and F. graminearum individually degraded the produced AF B1, B2, G1, G2, T-2 toxin, and DON from 5.0, 1.33, 0.76, 0.61, 0.63, and 0.38 ppm to 2.77, 0.66, 0.37, 0.15, 0.45, and 0.38 ppm using laccase, to 3.08, 1.25, 0.61, 0.39, 0.55, and 0.36 ppm using manganese peroxidase. The computational technique (docking) demonstrated the laccase and manganese peroxidase activities on aflatoxin and DON degradation. Consequently, the results suggested that laccase (PDB ID: 1HFU) and manganese peroxidase (PDB ID: 1MNP) promise innovative activity toward aflatoxin degradation, while 1HFU has more effect than 1MNP on DON degradation.

Today’s primary challenges include identifying efficient, affordable, and environmentally sustainable substances to serve as raw materials in industrial, agricultural, and medicinal applications. This study aimed to evaluate the chemical composition and biological properties (namely antioxidant and allelopathic activities) of the methanolic extract derived from the above-ground portions of Artemisia judaica collected in Jazan, Saudi Arabia. GC-MS was used to evaluate the chemical composition of the methanolic extract derived from Artemisia judaica. GC-MS analysis revealed a total of 22 volatile compounds in the extract. The most prominent compounds identified were 2-ethylhexanoic acid, 5-hydroxy-6-(1-hydroxyethyl)-2,7-dimethoxynaphtho-quinone, and piperitone. The extract demonstrated strong antioxidant activity in both the DPPH and ABTS radical scavenging assays, comparable to the standard antioxidant ascorbic acid. The IC₅₀ value for the extract was 31.82 mg/mL in the DPPH assay and 39.93 mg/mL in the ABTS testing. Additionally, the extract exhibited dose-dependent inhibition of seed germination, root growth, and shoot growth of the weed Chenopodium murale in allelopathic bioassays. The most significant suppression was observed in shoot growth with an IC₅₀ value of 45.90 mg/mL, which was lower than the IC₅₀ values for root development and seed germination of C. murale, recorded at 56.16 mg/mL and 88.80 mg/mL, respectively. Furthermore, the findings indicated that methanolic extracts had significant lethal toxic effects on the life cycle of Aedes aegypti. Future research will focus on extracting uncontaminated substances and evaluating the biological effects of each specific constituent.
