The glycoproteins ferritin and transferrin, which assist in carrying iron to various body parts, are used to store iron. In terms of iron uptake, storage, and excretion, equilibrium should be preserved. Ferroptosis is an iron-dependent form of cell death with traits like lipid peroxidation buildup and ROS generation. It is distinct from other forms of cell death visually and biochemically. Many cancer cells block ferroptosis by controlling different cell survival pathways. Compared to healthy, normal cells, cancer cells are more dependent on iron. A subgroup of tumor cells known as cancer stem cells has stem-like characteristics. These are in charge of metastasis and recurrence. The liver plays a significant part in the body's detoxifying process and is the primary iron storage organ. Numerous liver disorders are frequently accompanied by excessive iron accumulation. Due to excessive iron deposits, the liver is more vulnerable to oxidative damage, which can occasionally result in liver failure. Chemotherapy, which involves administering several medications to treat cancer, may be hazardous to the body's other cells. The ferroptosis condition and high iron accumulation can potentially impair liver function. A tailored drug delivery method may ameliorate the impact of excessive iron accumulation and favorably correlate with liver damage, consequently enhancing liver function.","PeriodicalId":10827,"journal":{"name":"Current Nanoscience","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138683472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a major cause of pollution and a potential health hazard when discharged into the environment without treatment. Standard adsorbents for removing heavy metals have certain limitations, like incomplete metal removal, high energy requirements, and undesirable waste generation. Therefore, the use of biosorbents is an effective alternative to conventional procedures. This critical review evaluates and summarizes the optimum results obtained from different papers covering different parameters such as biosorbent removal efficiency and their adsorption capacity, adsorbent dosage, and effect of pretreatment for removal of single and combination of heavy metals. The influence of pH, contact time, and sorbent dose on biosorption has been discussed. The Langmuir model and the Freundlich model are studied for various biosorbents, and the respective results are obtained and summarised. The pseudo-first and second-order models have been evaluated to study the sorption kinetics. Through this review, it can be concluded that biosorbents can be a promising alternative to treat industrial effluents, mainly because of their high metal binding capacity, low cost, high efficiency in diluted effluents, and environmentally friendly nature.","PeriodicalId":10827,"journal":{"name":"Current Nanoscience","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138574091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess the effectiveness of the membrane, in vivo experiments were conducted. Results: MTZ-NPs membrane had suitable mechanical strength; the drug was released by diffusion. Fourier Transform Infrared Spectroscopy (FTIR), differential scanning calorimetry (DSC), and X-ray diffraction (XRD) results showed the existence of metronidazole in the amorphous state in the membrane and had good compatibility with polymers. The in vitro cytotoxicity assays showed that the MTZ-NPs membrane was biocompatible. Cellular uptake of the C6-NPs membrane was significantly higher than that of the C6 membrane (p < 0.0001), signifying that encapsulating the drug in nanoparticles increases drug permeability and improves drug transport efficiency across the cellular membrane.

An asymmetric quantum well (AQW) made with ZnSe/CdSe/ZnS has been studied. More specifically, the dielectric continuum (DC) model has been employed to describe both the IP and the CF modes. Additionally, the Fermi golden rule has been used to estimate the electron transition rate within the asymmetric structure. Our numerical results show that the scattering rate for an electron which is localized at the bottom of the first subband above the well and drops within the quantum well, is characterized by regular peaks with an almost linear increase as the size of the QW increases. The emerge peaks are related to two different physical characteristics of the AQW system. These peaks are related to electron resonances and the threshold phonon emission (both CF and IP) called phonon resonances. The scattering rate of an electron which is localized at the bottom of the second subband above the well and makes transitions to all possible states within the quantum well gives only rise to phonon resonances. The research highlights the importance of the CF and IP modes on transition rates and their dependence on both the size of the quantum well and the asymmetry of the barrier materials.","PeriodicalId":10827,"journal":{"name":"Current Nanoscience","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138555804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
