Tyrosinase family enzymes (TYR, TRP1, TRP2) play pivotal roles in melanogenesis, making them targets for pigmentation modulation. Ascorbic acid (ASC) and coconut oil have shown promise in skin whitening. Inspired by these ASC esterified with coconut oil-derived medium-chain fatty acids (MCFAs) such as capric acid (ASC-CAP), caproic acid (ASC-CAPRO), caprylic acid (ASC-CAPRY) and lauric acid (ASC-LAU) are investigated via in silico analysis such as network pharmacology (NP), molecular docking and molecular dynamics (MD) simulation to understand their interaction with tyrosinase family enzymes.

Sugar beet is essential for sugar production, supporting food industries and renewable energy resources. A two-season field experiment (2021/2022 and 2022/2023) evaluated the effects of different potassium (K) sources, including traditional potassium sulfate (K), glauconite powder (G), and foliar glauconite extracts (20- and 40-mL L) extracted with sulfuric acid (GS), humic acid (GH), or hot water (GW), on soil properties, sugar beet yield, and sugar quality in saline soils. The results showed that GH and G treatments significantly improved soil properties by reducing electrical conductivity (EC), exchangeable sodium percentage (ESP), and bulk density (BD), while increasing organic matter (OM) and infiltration rate (IR).

This study explores the catalytic co-pyrolysis of cabbage waste (CW) and tire waste (TW) to enhance the yield and quality of bio-oil and syngas. Although CW is produced in large quantities from global cabbage cultivation, its lower hydrogen content limits its utility for fuel and chemical production. The co-pyrolysis process, utilizing char as a catalyst, presents a cost-effective approach to optimize product outputs by promoting the reforming of volatiles during thermal decomposition.

Introduction: Neodymium (Nd), a rare earth element (REEs), is widely utilized in industry. Although the detailed biological role of Nd in plant biology is unclear, recent reports have noted its oxidative phytotoxicity at concentrations higher than 200 mg kg soil. At present it is unclear if these detrimental effects could be offset by the global rise in atmospheric carbon dioxide concentration ([CO]) which has been shown to enhance photosynthesis and growth in a wide range of C3 plant species.

Selenium (Se) enhances the resistance of plants exposed to metal stress and can be used to lessen the impacts of toxic elements and to enhance the effectiveness of the plants used to clean up polluted sites. There is no information available about the optimum dose and form of Se to stimulate the camelthorn (Alhagi maurorum Medik) plant, which is one of the plants used in the phytostabilization of toxic elements. The impacts of selenate (Se-VI) and selenite (Se-IV) on the phytoremediation of toxic metals from loamy soils by camelthorn were investigated in a pot experiment.

Contamination of agricultural fields with bismuth (Bi) reduces crop yield and quality. Arbuscular mycorrhizal fungi (AMF) are known to enhance plant growth and crop production, even under stressful conditions such as soil contamination with heavy metals. The objective of this study was to investigate the effect of AMF on the mitigation of Bi-phytotoxicity in wheat (Triticum aestivum) and beans (Phaseolus vulgaris) and to provide a comprehensive evaluation of the physiological and biochemical basis for the growth and development of AMF-induced plants under Bi stress conditions.

Powdery mildew in cucumber is caused by the Podosphaera xanthii. No strategy for improving disease resistance can be successful in the absence of thorough insights into the physiological and biochemical responses of cucumber plants to powdery mildew. Therefore, a field experiment was executed to evaluate five commercial cucumber varieties (V: Dynasty, V: Long green, V:Desi Kheera, V:Thamin II, V:Cucumber 363) for their inherent immunity to powdery mildew.

Despite the wide utilization of chitosan nanoparticles (CSNPs) as a promising approach for sustainable agriculture, their efficiency under elevated CO (eCO), has not been evaluated. The interactive effects of CSNPs and eCO were evaluated on the growth and C and N metabolism of soybean plants. Plants were treated with CSNPs and grown under ambient CO (410 ppm, aCO) or eCO (645 ppm).
