“…Common alterations included, lifting of lamellae epithelium, hyperplasia of epithelial cells, hypertrophy of chloride cells, oedema, necrosis, formation venous sinus, fusion of secondary lamellae, curling of secondary lamellae, dilation of lamellar capillaries, clavate lamellae, atrophy of secondary gills lamellae, proliferation of cartilage tissue in primary lamellae (Table 1). These findings are comparable to those reported in other studies across the globe (Baiomy, 2016;Javed et al, 2017;Abiona et al, 2019;Lebepe et al, 2020).…”

This study aimed to assess the histopathological alterations and micronuclei induction in the gill, kidney and liver of common carp, Cyprinus carpio from Al-Huwaizah Marshes, Al-Hammar Marshes and Al-Sweap River. Thirty C. carpio were sampled at each locality using monofilament gillnets. Most prominent histopathological alterations recorded in the gill included formation venous sinus in primary lamellae, oedema, curling and distortion of primary lamellae fusion of secondary lamellae, hyperplasia of epithelial cells, necrosis, curling of secondary lamellae, severe dilation of lamellar capillaries, clavate lamellae formation at the tip of secondary lamellae, a proliferation of cartilage tissue in primary lamellae and lifting of the lamellar epithelium whereas congestion, fibrosis with proliferative inflammation, necrosis area, degenerated cells, vacuolar degeneration, vacuolation, nuclear pyknosis, hypertrophy of hepatocytes were reported in the liver. In the kidney, the most pronounced changes were necrosis of the hematopoietic tissue, hyaline droplet and activation of melanomacrophage centres. A higher prevalence of alterations was observed in the population from Al-Huwaizah Marshes, however, Al-Hammar population exhibited severe pathologies. Micronuclei frequency was significantly higher at Al-Huwaizah Marsh (p < 0.05) with low frequency being recorded at Al-Sweap River. This study attests to the effectiveness of histopathology and micronucleus induction as potential tools for discriminating the health of populations from different water bodies.

“…6 that the tested bacteria Staphylococcus aureus, Streptococcus faecalis, and Pseudomonas aeruginosa show higher efficacy than the other tested bacteria. When the studied material was added to the tested microorganisms, the cell membrane of the bacteria was disrupted [39][40][41][42][43][44][45][46][47] due to the presence of toxic silver and chromium ions. Adding Ag 0.5 Cr 2.5 O 4 nanoparticles, on the other hand, had no impact on fungal germs.…”

In this work, Ag0.5Cr2.5O4 nanochromite is fabricated utilizing a simple process (flash technique) at various annealing temperatures (room and 900 °C). The particle sizes of the materials under study were shown to be in the nanoscale range by atomic force microscopy (AFM) and field emission scanning electron microscopy (FESEM). Fourier transform infrared (FTIR) analysis was performed to verify the fabrication of the examined nanosamples and evaluate the bands behavior. The tetrahedral A-site (622.9 cm−1 for room temperature, 630.6 cm−1 for 900 °C) and the octahedral B-site (557.3 cm−1 for room temperature, 563.1 cm−1 for 900 °C) were the two prominent bands measured by FTIR analysis. The elastic characteristics of Ag0.5Cr2.5O4 nanoparticles were examined using FTIR measurements, revealing that the interatomic bonding of the atoms at 900 °C is higher than at room temperature. In addition, the elastic characteristics may be understood by analyzing the transverse and longitudinal velocities. Both Gram-positive and Gram-negative bacteria were effectively inhibited by the samples evaluated for antibacterial properties; however, neither sample showed any antifungal activity. Therefore, it is highly suggested that the investigated samples could be used in different applications, particularly biological ones.

Novel ratios of silver iron nanoparticles with the chemical formulas Ag2Fe2O4 with Ag/Fe ratio = 1/1 and Ag0.5Fe2.5O4 with Ag/Fe ratio = 1/5 were successfully synthesized using a flash auto-combustion technique at 400 oC. Structural properties were studied using XRD (X-ray diffraction), AFM (Atomic Force Microscopy), FESEM (Field Emission Scanning Electron Microscopy), and FTIR (Fourier transform infrared) analyses. The nanosize range determined from XRD analysis lies in 56.6-71.1 nm for Ag0.5Fe2.5O4 and Ag2Fe2O4 nanoparticles. The morphology was analyzed using AFM and FESEM to confirm that the particle size of both samples was spherical and nanosized with agglomeration. Fourier transform infrared (FTIR) analysis was performed to confirm nano-samples' formation. Both samples were measured using a vibrating sample magnetometer to study their magnetism. By increasing the concentration of iron ions, the saturation magnetization (Ms) increased 5-fold for Ag0.5Fe2.5O4 nanoparticles compared with Ag2Fe2O4 nanoparticles. Moreover, there is a relation between saturation magnetization and antimicrobial activity, in which high (Ms) gives high antibacterial activity. Thus, Ag0.5Fe2.5O4 had a high (Ms) and high efficacy against the tested bacteria. However, Ag2Fe2O4 showed high activity against Candida albicans. Moreover, a high-frequency application was measured from the magnetic measurements, showing that both samples could be applied at a very high frequency (VHF) in the radio wave range. Finally, both samples could be antibacterial materials, particularly Ag0.5Fe2.5O4 nanoparticles. However, Ag2Fe2O4 nanoparticles are strongly recommended for antifungal activity against Candida albicans.
