The aim of this study was to evaluate the photoprotective effect of fish bone-derived peptides (FBDPs) in a culture of UV-B-irradiated mouse fibroblasts and their anti-inflammatory activity in a model of stimulated human macrophages. The results showed that cell viability of FBDPs-treated and irradiated fibroblasts was higher than that of irradiated cells, as determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and lactate dehydrogenase (LDH) assay, after 25 and 60 s of treatment. Moreover, secretion of interleukin 1-beta (IL-1β) was decreased in FBDPs-treated inflamed macrophages, as determined by ELISA assay. Full article

Environmental pollution is a major threat to natural ecosystems, human health, and a challenge for the scientific world to adapt to the many side effects of industrialization and development. The paper presents the results of research designed to configure innovative water depollution hybrid technologies that use advanced oxidation processes (photocatalysis) combined with membrane separation processes, with a synergistic action of degradation of organic pollutants and separation by ultrafiltration, with the special purpose of water treatment at the point of use (POU). The hybrid processes are based on the development of photocatalytic ultrafiltration membrane systems made on quasi-inert support (PVDF) that incorporate nanostructures based on carbon nanotubes (MWCNT) doped with metal oxides. The laboratory model for the evaluation of hybrid systems is presented. It incorporates the photocatalytic ultrafiltration system in an experimental reactor with automatic control and data acquisition for the analysis of scale processes. The tests performed create the premise of elaborating the design specifications of the processes and their integration in real-scale industrial technologies.  Full article
