This course focuses on the application of the paediatrics nursing theoretical knowledge in the clinical area, Using the nursing process as a tool while giving nursing care to children with different medical –surgical problems. The student develops skills in observing and caring for well and sick children during their stages of development from birth to the adolescent, in the hospital .
Broad applications of iron oxide nanoparticles require an improved understanding of their potential effects on human health. In the present study, we explored the underlyingmechanismthrough which iron oxide nanoparticles induce toxicity in human breast cancer cells (MCF-7). MTT (3-(4, 5- dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) and lactate dehydrogenase assays were used to examine mechanisms of cytotoxicity. Concentration- and time-dependent cytotoxicity was observed in MCF-7 cells. Iron oxide nanoparticles were found to induce oxidative stress evidenced by the
Toxicity of nanoparticles depends on many factors including size, shape, chemical composition, surface area and surface charge. Silver nanoparticles (AgNPs) are likely to enter the aquatic ecosystems because of their multiple applications and pose a health concern for humans and aquatic species. Therefore, we used a freshwater snail Lymnaea luteola L (L. luteola) to investigate the acute toxicity and genotoxicity of AgNPs in a static-renewal system for 96 h. AgNPs caused molluscicidal activity in L. luteola, with 96- h median lethal concentrations (LC50) (48.10 lg L1).
