Recently, researchers in aquaculture become interested green synthesized nanomaterials as a superior alternative to current conventional methodologies. The present work shows that Moringa oleifera magnetite nanoparticles (MS-Fe3O4NPs) might offer possible substitute for common antibiotics treat Aeromonas sobria infection African catfish (Clarias gariepinus). MS-Fe3O4NPs demonstrated an vitro antibacterial potential (21 mm inhibition zone) against A. sobria. fish (n = 120; average body weight: 90 ± 3.5 g) were randomized into four groups (control, MS-Fe3O4NPs, sobria, and + sobria), where 1.2 mg/L of was used bath treatment seven-days. caused substantial elevations malondialdehyde, tumor necrosis factor-alpha, stress indices, hepato-renal biomarkers well lower survival rate. Moreover, apparent depletion the level antioxidants, protein profile, immune indicators consequences infection. Surprisingly, sobria-infected with recovered these parameters. Hence, water additive show promise fish.

Heavy metal toxicity is an important issue owing to its harmful influence on fish. Hence, this study a pioneer attempt verify the in vitro and vivo efficacy of magnetite (Fe3O4) nanogel (MNG) mitigating waterborne lead (Pb) African catfish. Fish (n = 160) were assigned into four groups for 45 days. The first (control) second exposed 0 1.2 mg L−1 MNG water. third fourth (MNG + Pb) water 69.30 Pb. In vitro, caused dramatic drop Pb level within 120 h. Pb-exposed group showed lowest survival (57.5%) among groups, with substantial elevations hepato-renal function lipid peroxide (MDA). Moreover, exposure remarkable decline protein-immune parameters hepatic antioxidants, along higher residual deposition muscles obvious histopathological changes liver kidney. Interestingly, adding aqueous fish relieved these alterations increased survivability. Thus, novel antitoxic agent against maintain health C. gariepinus.

A new insight into the synthesis of herbal plant (White poplar, Poplus alba) leave extract using chitosan nanocapsule was studied. The in vitro antibacterial activity white poplar (CWPNC) against Streptococcus agalactiae (S. agalactiae) determined. About 120 fish were categorized for 7 days four groups. first and second groups treated with 0 mg/L 3 CWPNC water, respectively, without being challenged; group a control. third fourth (CWPNC + S. CWPNC, challenged (0.5 × 107 CFU/mL). obtained results revealed that had an agalactiae. Moreover, infection caused significant elevation (p < 0.05) lipid peroxidation (malondialdehyde) hepatorenal biomarkers, as well lowest survival rate (33.33%). depletion level antioxidants (catalase superoxide dismutase) immune indicators (immunoglobulin, lysozyme activity, complement 3) consequences infection.

Phytotoxicity of trace elements (commonly misunderstood as ‘heavy metals’) includes impairment functional groups enzymes, photo-assembly, redox homeostasis, and nutrient status in higher plants. Silicon nanoparticles (SiNPs) can ameliorate element toxicity. We discuss SiNPs response against several essential (such Cu, Ni, Mn, Mo, Zn) non-essential (including Cd, Pb, Hg, Al, Cr, Sb, Se, As) elements. hinder root uptake transport the first line defence. charge plant antioxidant defence elements-induced oxidative stress.

Abstract Background In recent years, anthropogenic activities have released heavy metals and polluted the aquatic environment. This study investigated ability of silica-stabilized magnetite (Si-M) nanocomposite materials to dispose lead nitrate (Pb(NO 3 ) 2 toxicity in Nile tilapia African catfish. Results Preliminary tests were conducted determined median lethal concentration (LC 50 catfish be 5 mg/l. The sublethal concentration, equivalent 1/20 96-hour LC Pb(NO , was selected for our experiment. Fish each species divided into four duplicated groups. first group served as control negative group, while second (Pb group) exposed 0.25 mg/l (1/20 ). third (Si-MNPs) nanoparticles at a 1 mg/l, fourth + Si-MNPs) simultaneously Si-MNPs same concentrations Throughout experimental period, no mortalities or abnormal clinical observations recorded any treated groups, except melanosis nervous behavior observed some fish Pb group. After three weeks exposure, we analyzed hepatorenal indices, oxidative stress parameters, genotoxicity. Values alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), urea, creatinine significantly higher Pb-intoxicated groups compared both species. Oxidative parameters showed significant decrease reduced glutathione (GSH) along with increase malondialdehyde (MDA) protein carbonyl content (PCC) concentrations, well DNA fragmentation percentage However, these values nearly restored levels High accumulation liver gills least muscles Histopathological analysis tissue samples from Pb-exposed revealed brain vacuolation, gill fusion, hyperplasia, marked hepatocellular renal necrosis, contrasting Si-MNP which appeared an apparently normal structure. Conclusions Our results demonstrate that are safe effective aqueous additives reducing toxic effects (NO on through lead-chelating water before being absorbed by fish.

Applications of Cu2+-Loaded Silica Nanoparticles to Photothermal Therapy and Tumor-Specific Fluorescence Imaging

Journal of Functional Biomaterials, Journal Year: 2024, Volume and Issue: 15(4), P. 81 - 81

Published: March 25, 2024

Copper-based nanomaterials have been employed as therapeutic agents for cancer therapy and diagnosis. Nevertheless, persistent challenges, such cellular toxicity, non-uniform sizes, low photothermal efficiency, often constrain their applications. In this study, we present Cu2+-loaded silica nanoparticles fabricated through the chelation of Cu2+ ions by silanol groups. The integration into uniformly sized imparts a effect. Additionally, amine functionalization coating facilitates chemical conjugation tumor-specific fluorescence probes. These probes are strategically designed to remain in an ‘off’ state Förster resonance energy transfer mechanism until exposed cysteine enzymes cells, inducing recovery fluorescence. Consequently, our demonstrate efficient effect selectively enable imaging.
