Optimizing the fertilizer N rates at different irrigation levels for optimum yield of wheat and corn at reduced nitrate leaching losses

Optimum irrigation and fertilizer nitrogen (N) rates are important to improve crop yield at reduced environmental risks in the form of NO3-N leaching losses, without any financial loss. The study aimed to investigate the impact of rational irrigation and nitrogen management on wheat and maize crop yield vs. NO3-N leaching losses, with field experiments conducted at the experimental station, University of Agriculture Faisalabad, Pakistan, for two years, with wheat-fallow-corn seasons each year. Suction lysimeter were installed for collection of leachates while soil water balance was computed using the HYDRUS-1D model. We explored the various management strategies, including three irrigation and N levels (sub-optimal, optimal, and supra-optimal, referred to as I1, I2, and I3 for irrigation, and N1, N2, and N3 for nitrogen, respectively) for wheat and maize crops. The three irrigation levels were 325, 400, and 475 mm for wheat, and 375, 525, and 675 mm for maize crops. The three N-levels were 100, 130, and 160 kg ha-1 for wheat, and 220, 270, and 320 kg ha-1 for maize. The results indicated that increasing the irrigation and nitrogen levels significantly improved the growth and yield of both crops during both seasons. The highest grain yield of wheat (4.0 t ha-1) and maize (7.8 t ha-1) was observed with I3N3; however, I2N3 showed statistically no difference in yield, while showing significantly reduced (28.6%) annual NO3-N leaching losses of 23.8 kg ha-1, and the highest financial benefits of 780$. Sub-optimal levels of irrigation and N, though reduced the NO3-N leaching losses, caused significant yield losses, generally unacceptable to the farmers. Irrigation water use efficiency (WUEi) also improved by 12% in wheat and 20% in maize under I2 than that of the I3 level. Besides, considering economic profit, the highest value cost ratio (1.64 and 2.04 in wheat and maize, respectively) was achieved under the I2N3 treatment, as opposed to the other treatments. Based on comprehensive analysis, the I2N3 treatment is recommended for sustainable yield and minimal environmental risk in the wheat-maize cropping system. Moreover, it was observed that the rainy fallow period contributes 14.0-31.5% of the total NO3-N leaching losses. Further investigation is needed to minimize NO3-N leaching losses, especially during the rainy fallow period, by early maize sowing and increasing the efficiency of N fertilizer (such as fertilizer coating) under the flood irrigation system, to achieve the potential goals of sustainable productivity and environmental security.

Albumin-coated VS1 nanocrystals enable STARD3 inhibition and potentiate fluoropyrimidine therapy in colorectal cancer

Poor aqueous solubility remains a major obstacle to the translational development of targeted anticancer compounds. VS1, a first-in-class inhibitor of the cholesterol-transfer protein STARD3, has emerged as a promising chemosensitizing agent in colorectal cancer (CRC), but its clinical applicability is limited by its poor water solubility. Here, we combine structural biology, nanotechnology, and functional pharmacology to establish STARD3 inhibition as a delivery-enabled strategy to potentiate fluoropyrimidine therapy. To define the molecular basis of STARD3 inhibition, we solved the crystal structure of VS1 bound to the STARD3 ligand-binding domain at 2.1 [A] resolution, revealing direct occupation of the sterol-binding cavity. Molecular dynamics simulations confirmed a stable binding mode and identified the {Omega}1 loop as a dynamic gate regulating ligand binding and dissociation. To overcome the formulation barrier of VS1, we engineered carrier-free, albumin-coated nanocrystals through sonication-assisted nanocrystallization followed by surfactant exchange with human serum albumin. The resulting rod-shaped nanocrystals displayed nanometric size, narrow size distribution, sustained release, and improved aqueous dispersibility, increasing the apparent solubility of VS1 by more than 14-fold while preserving its molecular integrity and crystallinity. Biologically, VS1 selectively potentiated 5-fluorouracil (5-FU) in CRC cells, with synergistic effects restricted to 5-FU-sensitive models and associated with enhanced reactive oxygen species accumulation. Albumin-coated formulation retained the chemosensitizing activity of the free compound. In HCT-116 xenografts, combined treatment with albumin-coated VS1 nanocrystals and 5-FU significantly reduced tumor growth, prolonged tumor doubling time, and increased intratumoral necrosis without exacerbating systemic toxicity. Together, these findings establish that albumin-coated nanocrystals can overcome the delivery limitations of an insoluble STARD3 inhibitor and provide a formulation-enabled strategy to enhance fluoropyrimidine therapy in colorectal cancer.

Bioelectronic wearable sensors produced by computerized embroidery using a dual thread approach

Electronic textiles offer a promising route to wearable systems capable of continuous biophysical and biochemical monitoring. Their broader adoption remains limited by conductive threads that rarely support computerized embroidery (CEmb), reliable electronic integration, and reduced electrochemical capabilities due to coatings that degrade under bending, friction, or aqueous exposure. In this work, we use a dual-thread strategy that integrates silver-plated polyamide threads (AgPT) for high-conductivity pathways with PECOTEX, a chemically resilient PEDOT:PSS-coated cotton thread optimized for biochemical sensing. This approach preserves compatibility with CEmb, enhances electrochemical performance, and reduces cost by reserving AgPT for critical traces. We demonstrate a CEmb-compatible fabrication process for two wearable devices: a fully embroidered SmartBra for electrocardiography and a two-electrode ion sensor for potassium and sodium detection. We validate the design of our wearable dual-thread biosensors through laboratory characterization experiments and evaluate electrochemical sensing performance using a breast milk substitute, enabling realistic testing within womens health and infant-nutrition contexts. By focusing on scalable fabrication and meaningful applications, this work advances embroidered electronic textile systems toward practical, personalized healthcare monitoring.

Responses of Agricultural plants to Lithium pollution: Trends, Meta-Analysis, and Perspectives

Lithium (Li) is gaining attention due to rapid rise of modern industries but their ultimate fingerprints on plants are not well established. Herein, we executed a meta-analysis of the existing recent literature investigating the impact of Li sources and levels on plant species under different growth conditions to understand the existing state of knowledge. Toxic effects of Li exposure in plants varies as a function of medium and interestingly, more negative responses are reported in hydroponic media as compared to soil and foliar application. Additionally, toxic effects of Li vary with Li source materials and LiCl more negatively affected plant development parameters such as plant germination (n=48) and root biomass (n=57) and recorded highly uptake in plants (n=78), while LiNO3 has more negative effects on shoot biomass. The Li at <50 mg L-1 concentrations significantly influenced the plant physiological indicators including plant germination and root biomass, while 50-500 mg L-1 Li concentration influence the biochemical parameters. The uptake potential of Li is dose dependent and their translocation/bioaccumulation remains unknown. Future work should include complete lifespan studies of the crop to elucidate the bioaccumulation of Li in edible tissues and to investigate possible trophic transfer of Li. Environmental significanceAccumulation of Li sources is increasing in ecosystem compartments, and this might be vulnerable to plants.

Micro and Nanoplastics Interactions with Plant Species Trends, Meta-Analysis, and Perspectives

The ubiquitous presence of nano plastics (NPx) and micro plastics (MPx) in the environment has been demonstrated, and as such, the exposure scenarios, mechanisms of plant response, and ultimate risk must be determined. However, the current literature reports ambiguous outcomes and provides limited mechanistic insight into critical governing processes. Here, we performed a meta-analysis of the most recent literature investigating the effect of MPx/NPx on plant species under laboratory and field conditions so as to evaluate the current state of knowledge. Toxic effects of MPx/NPx exposure in plants varies as a function of plant species and interestingly, generally non-significant responses are reported in staple crops. NPx (<100 nm) more negatively affected plant development parameters (n=341) (n is total number of observations), photosynthetic pigments (n=80), and biochemical indicators (n=91) than did MPx (>100 nm). Surprisingly, NPx exposure yielded negligible effects on germination rate (n=17), although root morphology (n=45) was negatively affected. Alternatively, MPx negatively affected on germination (n= 27) and generally non-significant affect with regard to root morphology (n=64). The effect of MPx/NPx on plant health decreases with increasing exposure time. No specific trends were evident for the production of biochemical enzymes as related to MPx/NPx concentration or size. Future work should include crop full life cycle studies to highlight the accumulation of MPx/NPx in edible tissues and also to investigate potential trophic transfer of MPx/NPx. Furthermore, we provide a framework for additional investigative work to address these and other knowledge gaps and to enable accurate assessment of the fate and risk of these materials to environmental and human health. Environmental significanceAccumulation of plastic (MPx and NPx) particles is increasing in environmental compartments, and this might be threatened to agricultural plants.
