Mosses, in particular, demonstrate high phytoremediation potential due to their ability to accumulate heavy metals such as lead, zinc, copper, chromium, cadmium, and iron from contaminated soil and water. This review systematically examines 37 research articles published from 2000 to 2022, focusing on the on the use of mosses for phytoremediation. Moss species, such as <i>Funaria hygrometrica</i> Hedw, <i>Scopelophila cataractae</i> (Mitten) Brotherus, <i>Dicranum scoparium</i> Hedw, <i>Dicranum polysetum</i> Sw. ex anon, <i>Hypnum cupressiforme</i> Hedw, <i>Physcomitrium cyathicarpum</i> Mitt, <i>Barbula constricta</i> Mitt, and <i>Leptodictyum riparium</i> (Hedw.) Warnst. have been identified as ideal candidates for phytoremediation efforts. Specific species of mosses, such as <i>Dicranum</i> species, are noted for their excellent bioaccumulation capabilities of elements like vanadium, manganese, and rubidium, serving as indicators of air pollution. Additionally, <i>Hypnum cupressiforme</i> has proven to be a reliable indicator of sulfur dioxide in natural and anthropogenic sources. This comprehensive review highlights the significant phytoremediation potential of mosses, emphasizing their role as valuable bioaccumulators and indicators of heavy metals and pollutants. The findings highlight the necessity of further research to enhance the application of mosses in environmental management and remediation strategies, ultimately contributing to the development of sustainable and effective solutions for pollution control.</p></div>","PeriodicalId":491,"journal":{"name":"Biometals","volume":"38 1","pages":"89 - 101"},"PeriodicalIF":4.1,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142611868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The increase in microbial resistance because of harboured or inherited resistomes has been complicated by the lack of new and effective antimicrobial agents, as well as misuse and failure of existing ones. These problems have generated severe and growing public health concern, due to high burden of bacterial infections resulting from scarce financial resources and poor functioning health systems, among others. It is therefore, highly pressing to search for novel and more efficacious alternatives for combating the action of these super bacteria and their infection. The application of metallic nanoparticles (MNPs) with their distinctive physical and chemical attributes appears as promising tools in fighting off these deadly superbugs. The simple, inexpensive and eco-friendly model for enhanced biologically inspired MNPs with exceptional antimicrobial effect and diverse mechanisms of action againsts multiple cell components seems to offer the most promising option and said to have enticed many researchers who now show tremendous interest. This synopsis offers critical discussion on application of MNPs as the foremost intervening strategy to curb the menace posed by the spread of superbugs.

They catalyze the oxidation of ferrous iron, Fe²⁺, into ferric iron, Fe³⁺, which is essential in iron homeostasis and physiological functioning. The present study describes a novel spectrophotometric method of serum ceruloplasmin ferroxidase activity. This method is easy to perform; it is also sensitive, specific, and rapid. In this method, ferrous ions are used as a substrate for the enzyme, with either salicylic acid or sulfosalicylic acid being taken as a chromogenic compound. These chromogens easily form a colored complex with ferric ions but are not formed with ferrous ions. In the enzymatic reaction, the ceruloplasmin ferroxidase enzyme catalyzes the oxidation of ferrous to ferric ions. The resulting increase in ferric ion concentration is then measured spectrophotometrically, following the formation of the colored complex. The complex formed has maximum absorbance at 540 nm in the case of salicylic acid and 490 nm in the case of sulfosalicylic acid. Comparatively, it was tested against the standard method to ascertain the new method’s effectuality and reliability for assaying ferroxidase activity. The determined correlation coefficient amounted to 0.99, showing a strong correlation between the results obtained by the two methods. This new spectrophotometric technique offers a simplified, sensitive, specific, and fast means of estimating ferroxidase activity. It avoids using concentrated strong acids in the procedure and correlates excellently with the standard technique. This sets up a potential alternative for accurately determining ferroxidase activity in biological samples.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":491,"journal":{"name":"Biometals","volume":"37 6","pages":"1699 - 1712"},"PeriodicalIF":4.1,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142455156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leading to the oxidative stress and lipid peroxidation, the arylbipyridine platinum (II) complex showcases the significant cytotoxicity against the glioblastoma cells as shown by the MTT test. Using the 5-ethyl-2-deoxyuridine we study the proliferative activity of glioblastoma cells to affirm that arylbipyridine platinum (II) complex does not impede cell division or DNA replication. Staining by the MitoCLox dye and 2′,7′-dichlorodihydrofluorescein diacetate demonstrates that the glioblastoma cells treated with arylbipy-Pt exhibit a strong increase of the lipid peroxidation and the stimulation of the reactive oxygen species formation. The hypothesis that arylbipy-Pt promotes oxidative death of tumor cells is confirmed by control experiments using N-acetyl-L-cysteine as an antioxidant. Further evidence for the oxidative mechanism of action is provided by real-time PCR, which shows high expression levels for genes associated with the heat shock proteins <i>HSP27</i> and <i>HSP70</i>, which can be used as markers of tumor cell ferroptosis. To elucidate the chemical nature of the arylbipy-Pt complex activity, we perform ¹⁹⁵Pt NMR spectroscopy and cyclic voltammetry measurements under biologically relevant conditions. The results obtained clearly indicate the structural transformation of the arylbipy-Pt complex in the DMSO-saline mixture, which is crucial for its further antitumor activity via the oxidative pathway. The found correlation between the molecular structure of arylbipy-Pt and its effect on the tumor cell cycle paves the way for the rational design of Pt complexes possessing the alternative mechanism of antitumor activity as compared to DNA intercalation, providing possible solutions to the major problems such as toxicity and drug resistance.</p></div>","PeriodicalId":491,"journal":{"name":"Biometals","volume":"38 1","pages":"185 - 202"},"PeriodicalIF":4.1,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142455159","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
