In soil biota,higher and enduring concentration of heavy metals like cadmium(Cd)is hazardous and associated with great loss in growth,yield,and quality parameters of most of the crop plants.Recently,in-situ applications of eco-friendly stabilizing agents in the form of organic modifications have been utilized to mitigate the adverse effects of Cd-toxicity.This controlled experiment was laid down to appraise the imprints of various applied organic amendments namely poultry manure(PM),farmyard manure(FYM),and sugarcane press mud(PS)to immobilize Cd in polluted soil.Moreover,phytoavailability of Cd in wheat was also accessed under an alkaline environment.Results revealed that the addition of FYM(5–10 ton ha^(-1))in Cd-contaminated soil significantly increased germination rate,leaf chlorophyll content,plant height,spike length,biological and grain yield amongst all applied organic amendments.Moreover,the addition of FYM(5–10 ton ha^(-1))also reduced the phytoavailability of Cd by 73–85%in the roots,57–83%in the shoots,and 81–90%in grains of wheat crop.Thus,it is affirmed that incorporation of FYM(5–10 ton ha^(-1))performed better to enhance wheat growth and yield by remediating Cd.Thus,the application of FYM(5–10 ton ha^(-1))reduced the toxicity induced by Cd to plants by declining its uptake and translocation as compared to all other applied organic amendments to immobilize Cd under sandy alkaline polluted soil.

Although magnetic stirring is frequently used to enhance the kinetics for adsorption,chemical and biochemical reactions,the introduction of stirrers inevitably leads to the adsorption of analytes and thus interferes with the efficiency of the chemical process or reaction.In this work,magnetic Fe_(3) O_(4) nanorods with tunable length-to-diameter ratio were synthesized via a hydrothermal method and used as templates for the in-situ depositing of MIL-100(Fe) and gold nanoparticles.Such nanorod-based material can not only function as an adsorbent,nanozyme,and a heterogeneous catalyst for corresponding applications but also serve as a magnetic nanostirrer to enhance kinetics.As a proof-of-concept,the capture of bacteria pathogen,mimic-peroxidase-based colorimetric detection of hydrogen peroxide,and the catalytic reduction of selected organic pollutants were conducted using the as-synthesized Fe_(3) O_(4)@MIL-100(Fe)-Au nanostirrer with and without magnetic field.The results show that the rates of bacteria capture,mimetic enzyme reaction and catalysis were tremendously expedited.We believe this magnetic field-assisted approach holds great promise for future applications,because,not only does it eliminate the use of external magnetic stirrers and thereby decrease the risk of foreign pollution but also,is adaptable for nanoscale reaction systems where conventional stirring is not applicable due to size limitations.

Glinus lotoides ethanolic extract alleviates LPS-induced anxiety and depression-like behavior by modulating antioxidant and inflammatory biomarkers in rats

Objective:To explore the protective role of Glinus lotoides ethanolic extract in a depression model through modulating oxidant/antioxidant enzyme system and inflammatory status.Methods:Phytochemical constituents of Glinus lotoides ethanolic extract were evaluated qualitatively and quantitatively along with HPLC.Rats were divided into six groups.The normal control and the intoxicated groups received normal saline,and the standard group received imipramine,while the remaining groups received 100,300,and 500 mg/kg Glinus lotoides ethanolic extract.All groups received treatments for 14 d.Lipopolysaccharides(LPS)were then administered i.p.(0.83 mg/kg)to all groups except the normal control group.After 24 h,anxiety and depression-like behaviors were evaluated by performing behavioral analysis(open field,tail suspension,forced swim,sucrose preference test),and determining total oxidant status,total antioxidant capacity,catalase,and biochemical parameters[malondialdehyde,glutathione,superoxide dismutase,tumor necrosis factor(TNF)-alpha and interleukin(IL)-6].Results:Phytochemical studies confirmed the presence of phenols and flavonoids and HPLC analysis showed the presence of gallic acid,quercetin,chlorogenic,and caffeic acid.Total oxidant status was significantly decreased,while total antioxidant capacity was significantly increased in the Glinus lotoides ethanolic extract treated groups.Moreover,Glinus lotoides ethanolic extract diminished malondialdehyde,IL-6,and TNF-alpha levels,while increasing superoxide dismutase,catalase,and glutathione activities.Conclusions:Glinus lotoides ethanolic crude extract shows significant antidepressant activity by modulating oxidative and biochemical parameters that supports its folkloric use in traditional systems of medicine.
