Design and Synthesis of Magnolol Derivatives Using Integrated CNNs and Pharmacophore Approaches for Enhanced Parasiticidal Activity in Aquaculture.

Aquaculture is a rapidly growing sector of global food production, playing a vital role in poverty alleviation, food security, and income generation. However, it faces substantial challenges, particularly due to infections caused by the protozoan Ichthyophthirius multifiliis, leading to reduced yields and economic losses. In this study, two classes of magnolol derivatives (M1-M26) were synthesized and evaluated for their parasiticidal activity against I. multifiliis theronts and tomonts. Based on the determined EC50 values, two significant convolutional neural networks (CNNs) and pharmacophore models were developed, guiding the design and synthesis of three new compounds. Among these, compound new-1 exhibited superior parasiticidal efficacy both in vitro and in vivo compared to magnolol and the commercial parasiticide methylene blue, with EC50 values of 0.197 and 0.252 mg/L, respectively. Toxicity assays demonstrated that compound new-1 showed no significant harmful effects on goldfish and zebrafish embryos at effective concentrations. Further, in silico and experimental analyses identified CDK2 as a molecular target for compound new-1, which disrupted the reproduction and exerts parasiticidal activity against I. multifiliis. Additionally, compound new-1 exhibited antifungal activity against Aspergillus flavus with a MIC of ∼0.8 mg/mL, suggesting its potential application in food preservation. This study provides valuable insights into the development of magnolol-based agents for aquaculture.

Unveiling the Nutraceutical and Nutricosmetic Potential of Syzygium nervosum Flower Buds: A Focus on Phytochemicals and In Vitro Bioactivities

The flower buds of Syzygium nervosum are traditional edible and medicinal plant materials for the treatment of inflammation and stomach disorders. With rising demand for natural products in food and cosmetics, the nutraceutical and nutricosmetic potential of the flower buds has been evaluated in this work. The antioxidant activity of ethanol and water extracts of S. nervosum flower buds were detected through free radical scavenging (DPPH, ·OH, and ABTS) assays, and their inhibitory effects on tyrosinase and elastase enzymes were also evaluated. The ethanol extract (SNEE) exhibited stronger antioxidant activity and superior inhibitory effects on both enzymes compared with the water extract (SNWE), highlighting its potential for anti-aging and skin-whitening applications. Meanwhile, the LC-QTOF-MS was employed for the identification of key chemical molecules responsible for the nutricosmetic properties. Moreover, the enzyme inhibitory mechanisms of the flower bud extracts were further elucidated using inhibition kinetics and molecular docking methods. This research underscores the promising nutraceutical and nutricosmetic potential of S. nervosum flower buds so as to offer important information for further developing the edible flower resource as skin feeding bioactive ingredients.

China’s Well-Facilitated Farmland distribution dataset

China has less than 10% of the world’s arable land but must feed more than 20% of the global population. Both climate change and farmland degradation pose significant challenges to China’s food security. In 2009, Chinese government launched a nationwide, well-facilitated farmland (WFF) construction strategy to improve food production. The ultimate goal is to create 80 million hectare (1.2 billion mu) of WFF by 2030. Timely monitoring and generation of a public WFF dataset are critical for assessing China’s food production and security. However, such data are not currently available for research community or industrial sector. By compiling and synthesizing 377 reports and documents released by local authorities, this study created WFF dataset for 2020, covering both prefecture and provincial levels in China. Additionally, the provincial 2030 WFF targets and the current completion rates are included. This dataset has wide range of applications in food security, as well as agricultural water and nutrition managements for researchers and policymakers.

Soil health contributes to variations in crop production and nitrogen use efficiency.

Soil health affects both food production and environmental quality. However, quantifying its impact poses a substantial global challenge due to the scarcity of comprehensive soil health data and the complexity of disentangling its effects from other variables. Here we integrate high-resolution global data on soil, climate and farm management practices to assess the contribution of soil health to agricultural productivity. We show that soil health is responsible for approximately 12% and 22% of global variations in crop production and nitrogen use efficiency, respectively. While the influence of climate on crop yields is comparable to that of soil health, it is substantially overshadowed by the role of agricultural management, which accounts for roughly 70% of the global yield variation. In regions such as China, India and the central United States, the influence of soil health on crop yields and nitrogen use efficiency is less pronounced due to the dominant effects of farming practices, including the intensive use of fertilizers. Enhancing global soil health could increase crop yields by 7.8 Mt while reducing nitrogen surplus by 8.1 Mt worldwide by 2050. It is crucial to achieve global sustainable development through managing soil health beyond traditional agricultural practices and climate adaptation.

Strengthening regulatory compliance in the U.S. food industry to support health system resilience and public health preparedness

Foodborne illnesses continue to pose a significant threat to public health in the United States, with regulatory lapses in food production and distribution contributing to widespread outbreaks that strain already burdened healthcare systems. Incidents involving E. coli, Listeria monocytogenes, and Salmonella have highlighted critical vulnerabilities in the nation’s food safety infrastructure, resulting in increased hospital admissions, emergency response activation, and disruption of healthcare services. These failures reveal the urgent need to reframe food safety not only as a regulatory concern but as a critical component of public health preparedness and health system resilience. This paper examines the cascading impact of regulatory non-compliance in the U.S. food industry on health system capacity, especially during outbreaks and emergencies. It analyzes systemic gaps in current compliance frameworks and identifies missed opportunities to mitigate preventable health crises through stronger regulatory mechanisms. Drawing on real-world case studies, we demonstrate how insufficient inspections, inconsistent enforcement, and a fragmented compliance ecosystem undermine both food security and public health readiness. To address these challenges, we propose a multi-pronged strategy to strengthen regulatory compliance through enhanced digital audits, predictive analytics, workforce training, and integration of real-time monitoring technologies. These tools not only improve risk forecasting and outbreak prevention but also contribute to the agility and responsiveness of health systems during crises. Furthermore, we present actionable policy recommendations for federal and state agencies, emphasizing the alignment of food regulatory functions with national public health preparedness goals. By modernizing food safety oversight and embedding it within the framework of public health resilience, the U.S. can more effectively safeguard communities, reduce economic disruptions, and build a future-ready health system capable of withstanding both biological threats and systemic shocks. Keywords: Food Safety Surveillance, Public Health Integration, Risk Assessment, Regulatory Compliance.

A Donor-Acceptor Covalent Triazine Framework-based "On-Off-On" Electrochemiluminescence Aptasensor for Detecting Aflatoxin B1 with the Assistance of Nicking Endonuclease-powered DNA Walking Machine.

A designed "on-off-on" signal-switchable electrochemiluminescence (ECL) aptasensor based on a donor-acceptor (D-A) conjugated covalent triazine framework (CTF) has been constructed for the sensitive and accurate detection of aflatoxin B1 (AFB1) with the assistance of a nicking endonuclease (Nb.BbvCI)-powered DNA walking machine. The D-A conjugated CTF, generated from the reaction between 2,4,6-tris(4-formylphenyl)-1,3,5-triazine (TFPT) and tris(4-aminophenyl)methane (TAPM) (denoted as TFPT-TAPM-CTF), simultaneously serves as a superior ECL emitter and a platform for anchoring the bioprobe. The high ECL response of TFPT-TAPM-CTF can be quenched by the anchored Cy5-labeled single-strand DNA (Cy5-ssDNA) via ECL resonance energy transfer. Furthermore, the immobilization of the double-strand DNA generated between the AFB1-targeting aptamer and the DNA walker (Hp) reduces the ECL response of TFPT-TAPM-CTF. When detecting AFB1, the aptamer separates from the double-strand DNA to capture specific targets, resulting in the hybridization of the free Hp strand and Cy5-ssDNA. With the assistance of Nb.BbvCI, the released partial Cy5-ssDNA helps recover the ECL response of TFPT-TAPM-CTF to some extent, further liberating the Hp strand to autonomously bind to another Cy5-ssDNA and trigger a new cleavage process. In addition to its high selectivity and promising practicality, the constructed ECL aptasensor shows an ultralow detection limit of 0.59 pg·mL-1 within a wide range from 1.0 pg·mL-1 to 5.0 × 104 pg·mL-1. This work broadens the application of CTF in the food safety field and provides a new aptasensing strategy for the sensitive and precise inspection of mycotoxins in food products.

Status of Climate Change and Food Security in Kathmandu District

Climate change and its impact on agriculture and food security are serious global challenges we are facing today. This study investigates the specific impacts of climate change on agriculture and food security among farmers in Kathmandu district, Nepal. With farmers forming a significant portion of the agricultural workforce, understanding their unique challenges and adaptive strategies is crucial for developing effective interventions. Conducted over three months from April 22, 2024, to July 22, 2024, the research sampled 50 households using simple random sampling techniques. Data collection comprised both primary and secondary sources. Primary data were obtained through semi-structured interviews with respondents, field observations, and discussions with local facilitators, extension workers, and community leaders. Secondary data were gathered from published documents. The study's findings provided a detailed socio-economic profile of the respondents. Agriculture was the primary occupation for 67% of respondents, highlighting their dependence on this sector for livelihood. Land ownership patterns varied, with 34 respondents owning their land, 6 practicing sharecropping, and a few relying on leased land. Irrigation was primarily sourced from boreholes (58%), supplemented by drip irrigation, rainwater harvesting, and natural rainfall. Despite their efforts, 62% of respondents reported insufficient food production, leading to prevalent food shortages. Food insecurity was a significant issue, with 74% of respondents experiencing annual food shortages and only 24% having food security throughout the year. Many respondents resorted to purchasing food or working as laborers to meet their daily needs.

Intention to Purchase Foreign Halal Food Products among Muslim Consumers Using S-O-R Framework

The Islamic economy has rapidly growth due to the increase in the Muslim population and also their consumption expenditure. Due to the paucity of evidence on the factors that affect Muslim consumers to purchase foreign Halal food products, this study intends to investigate the factors that affect the intention of Muslim consumers to purchase foreign Halal food products. A research framework that underlies the Stimulus-Organism-Response model has been developed, with Halal certification, Halal knowledge, Halal awareness, and perceived reputation as stimuli, and attitudes as internal cognitive organisms, while purchasing intention as a response. Throughout the data collection, a total of 211 valid responses were gathered. The results from the partial least squares-structural equation modelling showed that Halal certification, Halal knowledge, Halal awareness, and perceived reputation positively influenced attitudes. Besides, consumers’ purchase intention is positively significantly affected by attitudes. These findings offer crucial understanding related to the subject matters as it would benefit the stakeholders in promoting foreign Halal food products in Muslim-dominated countries. Furthermore, the findings also further enrich the extant knowledge in Islamic marketing and consumer Halal consumption behaviour as the evidence was verified by utilizing the stimulus-organism-responses framework.

Physiological and morphological impact of physical activity and nutritional interventions to offset disuse-induced skeletal muscle atrophy.

Skeletal muscle tissue acts as a functional unit for physical movements, energy metabolism, thermogenesis, and metabolic homeostasis. In this literature review, the underlying mechanisms of skeletal muscle atrophy and the prevention strategies, including vigorous training and nutritional modifications are focused. Furthermore, the comparative analysis of multiple interventions is briefly explained. Ageing is an inevitable process often associated with cognitive impairment and physical decline due to muscular atrophy. Skeletal muscle atrophy is characterized by low muscle mass due to multiple underlying factors, i.e., genetic predisposition, ageing, inflammation, and trauma. The structural alterations include myofiber shrinkage, changes in myosin isoforms, decrease in myofiber diameter, and total protein loss. Furthermore, there is an imbalance in protein anabolic and catabolic reactions. This may be due to changes in multiple signal transduction pathways of protein degradation (i.e., caspase, calpain, ubiquitin protein degradation system, autophagy) and protein anabolism via the mTOR pathway. Consequently, certain pathophysiological factors associated with health disparities may reduce mobility and functional capacity to perform ADLs. To tackle this issue, novel strategies linked to physical movement, and dietary intake must be incorporated in life. Exercise poses multiple health benefits, including improved muscle mass and mobility. Diet diversification [particularly protein-rich meals] and the "whole food" approach (based on non-protein nutrients) may enhance intramuscular anabolic signaling and tissue remodeling. However, there is a pressing need to fund large-scale evidence-based trials based on modern machine learning techniques (AI-driven nutrition). Additionally, entrepreneurial platforms for commercialization of consumer-friendly food products must be initiated in future.

Mining bioactive components in agricultural crop and food production residue for sustainable solutions: In silico screening for skin anti-ageing properties.

Possible sustainable resources of beneficial compounds for various applications are agricultural crop and food production residues (ACFPR), which are supported by considerable efforts to characterize their compositions and biological activities. This knowledge can be utilized for the rational selection of agricultural crop residue extracts and their components and possible use in the development of value-added products, such as anti-ageing cosmetics. The appearance of wrinkles, pigmentation, and a reduction in skin elasticity are typical signs of ageing skin that are often alleviated by natural product-based preparations. Here, we use in silico approaches to identify natural compounds from agricultural crop and food production residues with the potential to alleviate symptoms of or reverse the skin ageing process. Target predictions combined with extensive database and literature searches were utilized to identify compounds present in ACR and proteins linked to skin ageing. The binding affinity of natural products to selected proteins using molecular docking and the respective intermolecular interaction analyses are predicted to provide an indicative measure of the compounds' potential for skin anti-ageing activity. A number of natural compounds with the potential to interact with protein targets such as collagenase, elastase, and hyaluronidase were identified. In addition to in silico findings, cytotoxicity assays were conducted using rose hip seed extracts against Hs294T (human metastatic melanoma, ATCC HTB-140) and MRC-5 (normal fetal lung fibroblasts, ATCC CCL 171), demonstrating selective cytotoxicity. ELISA assays revealed that rose hip seed extracts induced a significant increase in SIRT1 levels (160% of control) and a reduction in TGF-β levels (80% of control). These experimental results support the potential of agricultural crop residue extracts in modulating key proteins involved in skin ageing, reinforcing their viability as ingredients in anti-ageing cosmetic formulations. An analysis of the molecular relationships and pathways that organic substances from sustainable sources can affect offers the potential for developing formulations for skin rejuvenation with possible synergistic effects by utilizing the rational design of innovative skincare products and laying the framework for more effective screening of anti-ageing compounds for different applications.

Set-up and validation of end-point polymerase chain reaction for the detection of edible insect DNA – <i>Acheta domesticus</i> and <i>Tenebrio molitor</i> – in food products

Insects offer an alternative protein supply for both animal and human consumption. Recently, companies in Europe have begun insect production for use in food and animal feed. Following Regulation (EU) No. 2015/2283, edible insects are classified under the novel food category and can be marketed and consumed within the European Union. As a result, methods of authentication are necessary to verify the compliance of these insect-based products. In this study, two end-point polymerase chain reaction assays for the detection of the 16S rRNA gene of Acheta domesticus and Tenebrio molitor were fine-tuned and validated. The primer specificity was tested on insect samples, other animals, and plants, and the gene was amplified only in target samples. The limit of detection was evaluated using different food matrices contaminated with decreasing concentrations of insect powder and was below 0.05% (w/w).

Incorporating Stepping Stone Establishment into Rural Ecological Security Pattern Optimization: A Water–Energy–Food Coupling Perspective

Protecting ecological sources and restoring ecological stepping stones (ESSs) are key to constructing ecological security patterns (ESPs) in small-scale rural areas. Ecosystem services (ESs) associated with Water–Energy–Food (W-E-F) influence the ecological security of rural areas. However, how to construct rural ESPs to enhance the synergy and connectivity of W-E-F systems remains unclear. This study thus proposes a framework of rural ESP construction and optimization based on the coupling coordination analysis of ESs related to W-E-F, including Water yield, Carbon storage, and Food production. Using the Changsha–Zhuzhou–Xiangtan Green Heart region as a case, it identifies ecological sources and corridors through the coupling coordination degree (CCD) model and circuit theory. Moreover, it optimizes the ESP by incorporating the optimal ESS plan to improve source connectivity. The results show 14 ecological source patches covering a total area of 86.73 km2 and 117.21 km of ecological corridors. Three ESS plans are evaluated, with Option II proving optimal, increasing corridor length by 31.02% and source connectivity by 57.10%, which is based on the high CCD of three ESs. The “One Core, Three Zones, Four Corridors, and Multiple Points” scheme was defined as the ESP. This study underscores the significance of small-scale ecological restoration and advocates a shift from a “single ES” to a “coupled ESs” perspective. And it offers new insights aiming to enhance the source connectivity from the “patch–corridor–matrix” paradigms to the “patch–stepping stone–matrix” framework. It also provides feasible suggestions for balancing ecological protection and resource sustainability in rural areas.

Visualising and Valuing Urban Agriculture for Land Use Planning: A Critical GIS Analysis of Sydney and Neighbouring Regions

The loss of a city’s agricultural lands due to land use change through urban development is a global problem, as local food production is an essential green infrastructure for intergenerational sustainability. Like many cities, much of Sydney’s rapid urban development occurs on land previously used for food production. Sydney has one of the highest rates of urban growth among Western cities and a planning strategy that marginalises its agricultural productivity. To better understand and advocate for Sydney’s capacity for food production we explore all available government datasets containing agricultural biophysical capacity using a critical GIS approach. Employing various spatial-data visualisations to contextualise agricultural production, we examine inherent biophysical agricultural capacity in Sydney and comparable regions along the eastern coast of NSW. Our approach interrogates the notion that Sydney’s metropolitan landscape is of low inherent biophysical quality for agriculture, thereby challenging current development and planning orthodoxy and policy. In ascertaining Sydney’s comparative capacity for agriculture we find that, despite current metropolitan planning policy, datasets reveal western Sydney is biophysically well suited for agriculture. Sydney overall is comparable to five of six other coastal regions of NSW and superior to at least two. While acknowledging metropolitan land use complexities that shape agricultural production in practice, we argue for improved critical application and contextual understanding of existing agricultural datasets to better inform future planning policy to advance regional food security and aid long-term sustainability.

Digestibility and Quality Characteristics of Noodles with Added Malic-Acid-Modified Wheat Starch

Starch digestion raises blood glucose levels and is associated with cardiovascular diseases, diabetes, metabolic syndrome, and obesity. Hence, developing methods for controlling starch digestion is important. In this study, we prepared noodles from wheat flour containing malic-acid-modified starch (MAS), which contains a high proportion of thermostable resistant starch (RS). The quality and digestibility characteristics of these MAS-added noodles were evaluated to determine the optimal formulation. MAS was prepared by physicochemically modifying native wheat starch by adding 4 M malic acid and heating at 130 °C for 7 h. MAS-added noodles were produced by preparing a flour mixture in which 5–30% wheat flour was replaced with MAS. Compared to traditional wheat flour noodles, the addition of MAS resulted in inferior texture, extensibility, and cooking properties, along with higher solid losses, which negatively affect noodle quality. Nevertheless, less-rapidly digestible starch and more RS were observed at higher MAS levels. The inclusion of 10% MAS was found to afford the highest RS content while maintaining noodle quality similar to that of commercially available wheat flour; this formulation was determined to be optimal for producing MAS-added noodles. Therefore, MAS, with its enhanced thermostable RS content, is a promising low-calorie ingredient for use in the food industry. Further research into MAS and the development of MAS-based food products may promote the development of new and diverse low-calorie food options.
