A cellulose xanthate (CX) based polymer hydrogel has been synthesized using free radical graft polymerization technique. Two monomers Acrylic Acid (AA) and Acrylonitrile (AN) were reacted with to synthesize the desired CX-g-poly(AA-co-AN). The characterized by various techniques viz. Thermo-gravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), UV-visible (UV), Field emission scanning electron microscope (FESEM) Point zero charge (PZC). This employed for removal of toxic metal ions from wastewater. maximum percentage found be 97.5 (±4.87)% Cu2+ 96.1 (±4.80)% Co2+ under optimum pH 6. calculated adsorption capacities have 330.03 (±35.3) mg/g 325.73 (±22.4) Langmuir Adsorption isotherm model. thermodynamic parameters depicted that process was endothermic, spontaneous. kinetics data shows excellent fit pseudo-second-order kinetic exhibits a high swelling ratio 846.85 (±42.36) g/g retention 50.12 (±2.50) % in distilled water. Also, showed good reusability, exhibiting 83.2% 81.3% fifth cycle.

Selenium-Doped Copper Formate Nanozymes with Antisenescence and Oxidative Stress Reduction for Atherosclerosis Treatment

Nano Letters, Год журнала: 2025, Номер unknown

Опубликована: Янв. 17, 2025

Atherosclerosis, resulting from chronic inflammation of the arterial wall, serves as underlying cause multiple major cardiovascular diseases. Current anti-inflammatory therapies often exhibit limited and unsatisfactory efficacy. To address this, we have designed a selenium-doped copper formate (Cuf-Se) nanozyme for treatment atherosclerosis, which possesses superoxide dismutase (SOD) glutathione peroxidase (GPx)-like activities. The Cuf-Se can efficiently scavenge reactive oxygen species (ROS), inhibit cellular senescence, prevent formation foam cells. It acts on macrophages to reduce ROS levels lipid oxidation, thereby significantly inhibiting inflammation-related processes. Notably, while cell formation, also alleviates endothelial cells senescence. After intravenous administration, effectively inhibits atherosclerosis in mice through synergistic effects antisenescence antioxidant properties, reducing plaque area by approximately 5-fold. This study provides an effective strategy atherosclerosis.

Abstract The concentration of harmful metal ions is growing globally, which raises the risk to both human and ecological health. use “adsorption” technique has been found be very effective, for removal toxic ions. Among other things, hydrogels as an adsorbent work effectively aquatic pollutants. newly designed potato starch‐xanthate (SX) based hydrogel (SX‐modified hydrogel) synthesized using a mixture acrylamide (AAm) acrylic acid (AA) monomers, with help free‐radical graft copolymerization technique. SX‐modified characterized by several analytical techniques, namely, UV–visible (UV–vis) spectroscopy, Fourier transform infrared (FTIR) gel permeation chromatography (GPC), thermogravimetric (TG) analysis, point zero charge (ΔpH PZC ) x‐ray diffraction (XRD) scanning electron microscope (SEM) analysis. main objective current remove Cu 2+ Co from wastewater well study swelling water retention properties hydrogel. ratio 312.31, 374.01, 410.20 g/g at optimum pH 10, temperature 35°C, time 675 min in gray wastewater, tap water, distilled respectively. maximum percentage 97.7% 94.2%, respectively, conditions.

Copper homeostasis and copper-induced cell death in tumor immunity: implications for therapeutic strategies in cancer immunotherapy

Biomarker Research, Год журнала: 2024, Номер 12(1)

Опубликована: Окт. 31, 2024

Copper is an important trace element for maintaining key biological functions such as cellular respiration, nerve conduction, and antioxidant defense. Maintaining copper homeostasis critical human health, its imbalance has been linked to various diseases, especially cancer. Cuproptosis, a novel mechanism of copper-induced cell death, provides new therapeutic opportunities metal ion regulation interact with fate. This review insights into the complex mechanisms metabolism, molecular basis cuproptosis, association cancer development. We assess role cuproptosis-related genes (CRGs) associated tumorigenesis, their importance prognostic indicators targets, impact on tumor microenvironment (TME) immune response. Ultimately, this highlights interplay between copper, immunotherapy.
