    The use of nanosized titanium dioxide (TiO2) and zinc oxide (ZnO) in the suspension form during treatment makes the recovering and recycling of photocatalysts difficult. Hence, supported photocatalysts are preferred for practical water treatment applications. This study was conducted to investigate the efficiency of calcium alginate (CaAlg) beads that were immobilized with hybrid photocatalysts, TiO2/ZnO to form TiO2/ZnO-CaAlg. These immobilized beads, with three different mass ratios of TiO2:ZnO (1:1, 1:2, and 2:1) were used to remove Cu(II) in aqueous solutions in the presence of ultraviolet light. These beads were subjected to three cycles of photocatalytic treatment with different initial Cu(II) concentrations (10-80ppm). EDX spectra have confirmed the inclusion of Ti and Zn on the surface of the CaAlg beads. Meanwhile, the surface morphology of the beads as determined using SEM, has indicated differences of before and after the photocatalytic treatment of Cu(II). Among all three, the equivalent mass ratio TiO2/ZnO-CaAlg beads have shown the best performance in removing Cu(II) during all three recycling experiments. Those TiO2/ZnO-CaAlg beads have also shown consistent removal of Cu, ranging from 7.14-62.0ppm (first cycle) for initial concentrations of 10-80ppm. In comparison, bare CaAlg was only able to remove 6.9-48ppm of similar initial Cu concentrations. Thus, the potential use of TiO2/ZnO-CaAlg beads as environmentally friendly composite material can be further extended for heavy metal removal from contaminated water.

    BACKGROUND: Age-related macular degeneration (AMD) is a progressive retinal disorder and a major cause of irreversible blindness in the elderly, with complement pathway dysfunction playing a key role in its pathogenesis.

    METHODS: The present aims to examine the impact of CFH rs1061170 (Y402H), C2 rs9332739 (E318D), and C3 rs2230199 (R102G) gene polymorphisms and AMD risk, in addition, Deleterious missense SNPs in CFH, C2, and C3 were analyzed for stability, conservation, and structural impact using multiple computational approaches. Relevant studies were searched in PubMed, Web of Science, and Google Scholar databases between the years Jan 2020 and 30 April 2026 and covered a total of nine case-control articles.

    RESULTS: Meta-analysis demonstrated significant associations of CFH rs1061170 and C3 rs2230199 polymorphisms with AMD susceptibility under specific genetic models (p
