        1 - Albumin binding and cytotoxicity assay of nickel oxide nanoparticles against primary hippocampal neural cells

        Nanoparticles (NPs) have been widely used in medical and therapeutic applications. However, their albumin binding and their cytotoxicity assays have not been well explored. In his study, the interaction of NiO NPs with human serum albumin (HSA) was explored by circular dichroism (CD) study, molecular docking and dynamic studies. Afterwards the cytotoxicity of NiO NPs against primary hippocampal neural cells was explored by MTT and morphological assays. The CD experiment revealed that NiO NPs do not stimulate some significant structural changes within the HSA structure. The molecular docking investigation showed that NiO nanoclusters bind to HSA molecule through hydrophilic interactions and NiO nanoclusters with different sizes show different docking scores for interaction with HSA. The Molecular dynamic study also revealed that minor structural changes in HSA structure occur after interaction with NiO NPs. Cellular assay displayed that incubation of NiO NPs with primary hippocampal neural cells for 24 h triggered a significant cytotoxicity and morphological changes. Therefore, it may be concluded that although NiO NPs may show a strong binding affinity to HSA and do not induce a remarkable rearrangement in the structure of HSA, they may induce some unwanted effects on the cell viability.

        Palladium nanoparticles (Pd-NPs) have various applications in industries, such as: Biomedicine, Sewage treatment, Electronics, and Catalytic processes. Different studies on NP have shown that they have negative impacts on different cell categories in vitro. Despite extensive considerations, the molecular mechanism of Pd-NPs toxicity has remained elusive thus far. Therefore, in this paper, we investigated the toxicity of Pd-NPs by evaluating their effects on human lymphocyte. Blood lymphocyte cells were initially isolated by ficoll solution and were exposed to Pd-NPs and Pd (II) ions. Then, we examined oxidative stress, cell cycle and apoptosis employing flow cytometry. We found the NPs administration suppressed cell growth which in turn resulted in cell apoptosis. Also, cell cycle stopped at sub G1 phase, resulting in DNA damage as well as profound ROS increase. Our results showed that Pd-NPs treatment for 24 hours led to apoptosis, oxidative stress, as well as cell cycle blockage. It is notable that Pd (II) ions induced more severe toxicity. Our findings provide valuable insights on Pd-NPs toxicity. Manuscript profile
