    Abstract The study was aimed at divulging an eco-friendly antimicrobial finish on 100 % silk woven fabric. The leaves’ extract of Azadirachata indica, Butea monosperma and Litche chinensis were used as the development of eco-friendly antimicrobial finish. The antimicrobial property and comfort related property were checked before and after applying antimicrobial finish. In comfort related property absorbency & air permeability were checked. The ASTEM E2149 Shake Flask method was used to check antimicrobial finish and AATCC method was used for checking fabric property. One way ANOVA statistical test was applied for analysis of results. The FTIR and SEM results showed the presences of finish on fabrics. In comfort related property, absorbency and air permeability was increased. The results showed that antimicrobial finish made 100% reduction against microorganism up to 25 washes which can be used in making reusable masks fight against COVID- 19.

    Abstract The excessive use of agrochemicals to ensure food security under the conditions of a growing population, global climate change, weather extremes, droughts, wasteful use of freshwater resources, and land degradation has created severe challenges for sustainable crop production. Since the frequent and abrupt environmental changes are outcompeting the existing agricultural technologies of crop production systems to meet food security, the development and use of modern technologies and nature-based solutions are urgently needed. Nanotechnology has shown potential for revolutionizing agri-production and agri-business in terms of nanofertilizers and nanoparticles for crop protection. Furthermore, in the recent past, biochar has been identified as a negative emission technology for carbon sequestration and soil fertility improvement. However, supply chain issues for biochar, due to feedstock availability, challenges its worldwide use and acceptability. Meanwhile progress in algae research has indicated that, algae can be utilized for various agro-ecosystem services. Algae are considered an efficient biological species for producing biomass and phytochemicals because of their high photosynthetic efficiency and growth rate compared to terrestrial plants. In this context, various options for using algae as a nature-based solution have been investigated in this review; for instance, the possibilities of producing bulk algal biomass and algal-based biofertilizers and their role in nutrient availability and abiotic stress resistance in plants. The potential of algae for biochar production (hereafter “phycochar” because of algal feedstock), its elemental composition, and role in bioremediation is discussed. The potential role of agal nanoparticles’ in mitigating abiotic stress in crop plants was thoroughly investigated. This review has effectively investigated the existing literature and improved our understanding that, algae-based agro-solutions have huge potential for mitigating abiotic stresses and improving overall ...

    Abstract The unpredictable climatic perturbations, the expanding industrial and mining sectors, excessive agrochemicals, greater reliance on wastewater usage in cultivation, and landfill leachates, are collectively causing land degradation and affecting cultivation, thereby reducing food production globally. Biochar can generally mitigate the unfavourable effects brought about by climatic perturbations (drought, waterlogging) and degraded soils to sustain crop production. It can also reduce the bioavailability and phytotoxicity of pollutants in contaminated soils via the immobilization of inorganic and/or organic contaminants, commonly through surface complexation, electrostatic attraction, ion exchange, adsorption, and co-precipitation. When biochar is applied to soil, it typically neutralizes soil acidity, enhances cation exchange capacity, water holding capacity, soil aeration, and microbial activity. Thus, biochar has been was widely used as an amendment to ameliorate crop abiotic/biotic stress. This review discusses the effects of biochar addition under certain unfavourable conditions (salinity, drought, flooding and heavy metal stress) to improve plant resilience undergoing these perturbations. Biochar applied with other stimulants like compost, humic acid, phytohormones, microbes and nanoparticles could be synergistic in some situation to enhance plant resilience and survivorship in especially saline, waterlogged and arid conditions. Overall, biochar can provide an effective and low-cost solution, especially in nutrient-poor and highly degraded soils to sustain plant cultivation.

    Abstract Wastewater from tanneries may ruin agricultural fields by polluting them with trace metals. The synthesis of nanoparticles (NPs) from algal sources and their application could help in decreasing hazardous materials, for environmental safety. The potential of zinc oxide nanoparticles made from Oedogonium sp. was evaluated for removal of heavy metals from leather industrial wastewater. Synthesized algal nanoparticles (0 (control), 0.1, 0.5, and 1 mg) were applied to treat wastewater by using different concentrations of leather industrial effluents (0%, 5%, 10%, 15%, and 100%) for 15, 30, and 45 d. The wastewater collected was dark brown to black in color with very high pH (8.21), EC (23.08 μs/cm), and TDS, (11.54 mg/L), while the chloride content was 6750 mg/L. The values of biological oxygen demand (BOD) and chemical oxygen demand (COD) ranged between 420 mg/L and 1123 mg/L in the current study. Prior to the application of nanoparticles, Cr (310.1), Cd (210.5), and Pb (75.5 mg/L) contents were higher in the leather effluents. The removal efficiency of TDS, chlorides, Cr, Cd, and Pb was improved by 46.5%, 43.5%, 54%, 57.6%, and 59.3%, respectively, following treatment with 1 mg of nanoparticles after 45 d. Our results suggested that the green synthesis of ZnO nanoparticles is a useful and ecofriendly biotechnological tool for treating tannery effluents, before they are discharged into water bodies, thus making the soil environment clean.

    Abstract Objective: To focus on the evaluation of antimicrobial and antioxidant activity of two endangered medicinal plants Aconitum heterophyllum (A. heterophyllum) and Polygonum bistorta (P. bistorta). Materials: Plant extracts were obtained by using microwave assisted extraction method. The in vitro antifungal activity of A. heterophyllum and P. bistorta extracts were determined by measuring diameters of inhibitory zones of these extracts against Aspergillus niger and Alternalia solani. Results: Methanolic extract of A. heterophyllum showed significant (P≤0.05) antifungal activity against both the tested organisms. It was also observed that ethanolic extracts of P. bistorta also had good antifungal activity against the tested fungal strains as compared to the methanolic extracts. It showed significant antifungal activity (P≤0.05) against both the tested strains. Antioxidant activity of methanolic and ethanolic extracts of A. heterophyllum and P. bistorta were also measured using a radical scavenging method. Ascorbic acid was used as a standard. Conclusions: It was observed that A. heterophyllum and P. bistorta have significant antioxidant activity. Higher antioxidant activity was recorded in methanolic extract of A. heterophyllum as compared to its ethanolic extract. However, in case of P. bistorta ethanolic extract of the plant exhibited higher antioxidant potential than methanolic extracts. Hence both of these plants have significant antimicrobial as well as antioxidant potential.

    Abstract The presented work is destined to review the advances that had been made to study the role of thyroid hormone and thyroid hormone nuclear receptors in regulating the gene expression. Triiodothyronine (T3) and tetraiodothyronine (thyroxine or T4) are most important thyroid hormones. The thyroid hormones bind to their specific nuclear hormone receptors, as ligand, and play important role in gene expression and transcriptional gene regulation in human and higher animals. Thyroid hormone receptors form heterodimers by making combination with retinoid X receptors. The capability of heterodimerization of thyroid hormones generates novel complexes which allow altered specificity and higher affinity for DNA-receptor binding. Thyroid hormone receptors work as ligand activated transcription factor and play with transcriptional gene expression process. The consensus structural features of thyroid hormone receptors are N-terminal regulatory domain that contains activation function, the domain for strong gene expression and the domain for binding to DNA. The structures for individual domains have been extensively and reviewed through several latest and successful techniques.
