Phytoremediation is an effective alternative to remove heavy metals from contaminated aqueous environments. In the present research, <i>Chenopodium album</i> L. was examined for the remediation of waters contaminated with Cd, Pb, and Hg. Studies were carried out in waters containing each metal separately (monometallic aqueous systems) and in mixtures (trimetallic aqueous systems). First, the adaptation of <i>Chenopodium album</i> to different concentrations of Hoagland's nutrient solution (HNS) was evaluated, then, a phytotoxicity study was carried out to determine the appropriate concentrations of each metal to test the tolerance of the plant during the accumulation study, and finally, the bioaccumulation capacity of <i>Chenopodium album</i> for Cd, Pb, and Hg was evaluated. <i>Chenopodium album</i> showed tolerance to levels of 5 mg/L Hg and 10 mg/L Cd and Pb in 25% HNS. The bioaccumulation tests showed that <i>Chenopodium album</i> can remediate Cd, Pb, and Hg contaminated waters in both monometallic and trimetallic aqueous systems. These findings suggest important future applications in the food industry for the production of <i>Chenopodium album</i> as we demonstrate that this species adapts and grows in hydroponic media. In particular, the ability of <i>Chenopodium album</i> to adapt to extreme conditions could be exploited for further studies on phytoremediation of heavy metals in river water, irrigation water, wastewater, effluents, and mine tailings.</p>","PeriodicalId":21726,"journal":{"name":"Scientifica","volume":"2024 ","pages":"6842159"},"PeriodicalIF":2.3,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11655145/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142855073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiments were conducted during the winter season of 2022-2023 (November to February) at the University of the Punjab in Lahore, Pakistan. The study involved four wheat varieties: Akbar-2019, Galaxy-2013, Ujala-16, and Chakwal-86. The study utilized a factorial design with three replicates, examining three Cd levels (0.1 mM, 0.2 mM, and 0.3 mM) and two SA levels (0.5 mM and 0.9 mM). SA was applied as a seed priming agent, while cadmium sulfate (CdSO₄) solution induced Cd toxicity. Various growth parameters, including plant height, total plant length, leaf length, leaf breadth, and leaf area, were measured alongside physiological and biochemical parameters such as total chlorophyll content, carotenoid content, oxidative stress indicators (MDA and H₂O₂), and antioxidants (total soluble protein, CAT, and APX)-to assess the effects of SA under Cd stress. The results indicated that the application of 0.5 mM SA resulted in the highest vegetative growth and maximum physiological and biochemical parameters, while 0.3 mM Cd significantly reduced growth. The performance of the treatments was observed in the following order: 0.5 mM SA > 0.3 mM Cd. Ujala-16 showed intermediate growth and yield, while Chakwal-86 had the lowest growth rate and yield. The study demonstrated that SA mitigates Cd stress effects, with 0.9 mM SA and 0.1 mM Cd yielding the highest growth, second only to 0.5- and 0.9-mM SA treatments. These findings underscore the potential of SA to enhance wheat growth and yield in Cd-contaminated soils. In conclusion, SA is suggested as a beneficial treatment for improving productivity and economic returns in Cd-stressed areas.

It is also capable of utilizing a wide range of substrates. <i>B. subtilis</i> attractiveness and efficiency can be further enhanced using mutagenesis. In this study, a novel approach to creating mutant strains with enhanced protein and AA content was experimentally validated. The method is based on the application of AA inhibitors for selective pressure to ensure the growth of mutants with enhanced protein and/or AA synthesis capacity. For AA inhibitors, three herbicides were used: glufosinate-ammonium (GA), L-methionine sulfoximine (MSO), and S-(2-aminoethyl)-L-cysteine (AEC). Initially, AA inhibitor doses for the complete inhibition of wild-type (WT) <i>B. subtilis</i> strain were determined. Then, <i>B. subtilis</i> was treated with EMS chemical mutagen and created mutants were cultivated on a medium containing inhibitory dose of AA inhibitors.

The primary objectives of this study were to evaluate and compare the efficacy of Invisalign and fixed orthodontic appliances in terms of the amount and rate of OTM. Specifically, the study aimed to determine if there was a statistically significant difference between these two treatment modalities in achieving OTM and to assess whether treatment duration differs significantly between Invisalign and traditional fixed appliances. This investigation seeks to address the existing gaps in the literature by providing a clear comparison based on recent empirical evidence, thereby contributing to more informed treatment decisions in orthodontic practices. <b>Methodology:</b> Relevant MeSH keywords and Boolean operators were selected by a team of reviewers to search several online databases for papers that were in accordance with the objectives of our review. <b>Results:</b> At the end of the search protocol, 10 studies were deemed to be eligible for inclusion in the review. The pooled analysis revealed a statistically significant reduction in treatment time for patients using Invisalign compared to those with fixed appliances, with a total OR of 0.61 [95% CI 0.43, 0.85]. No significant heterogeneity was detected (<i>I</i> ² = 0%), and the test for overall effect was significant (<i>Z</i> = 2.86, <i>p</i>=0.004).
