Nanotechnology plays a key role in the development of innovative scaffolds for bone tissue engineering(BTE)allowing the incorporation of nanomaterials able to improve cell proliferation and *** this study,Mg-HA-Coll type I scaffolds(Mg-HA-based scaffolds)were nanofunctionalized with gold nanorods(Au NRs),palladium nanoparticles(Pd NPs)and maghemite nanoparticles(MAG NPs).Nanofunctionalized Mg-HA-based scaffolds(NF-HA-Ss)were tested for their ability to promote both the proliferation and the differentiation of adipose-derived mesenchymal stem cells(hADSCs).Results clearly highlight that MAG nanofunctionalization substantially improves cell proliferation up to 70% compared with the control(Mg-HA-based scaffold),whereas both Au NRs and Pd NPs nanofunctionalization induce a cell growth inhibition of 94% and 89%,*** evidences were found for the osteoinductive properties showing relevant calcium deposits(25% higher than the control)for MAG nanofunctionalization,while a decreasing of cell differentiation(20% lower than the control)for both Au NRs and Pd NPs *** results are in agreement with previous studies that found cytotoxic effects for both Pd NPs and Au *** excellent improvement of both osteoconductivity and osteoinductivity of the MAG NF-HA-S could be attributed to the high intrinsic magnetic field of superparamagnetic MAG *** findings may pave the way for the development of innovative nanostructured scaffolds for BTE.

Since its identification in 1989, hepatitis C virus(HCV) has emerged as a worldwide health problem with roughly 185 million chronic infections, representing individuals at high risk of developing cirrhosis and liver cancer. In addition to being a frequent cause of morbidity and mortality due to liver disease, HCV has emerged as an important trigger of lymphoproliferative disorders, owing to its lymphotropism, and of a wide spectrum of extrahepatic manifestations(HCV-EHMs) affecting different organ systems. The most frequently observed HCV-EHMs include mixed cryoglobulinemia and cryoglobulinemic vasculitis, B-cell non-Hodgkin's lymphoma, nephropathies, thyreopathies, type 2 diabetes mellitus, cardiovascular diseases, and several neurological conditions. In addition, neuropsychiatric disorders and neurocognitive dysfunction are reported in nearly 50% of patients with chronic HCV infection, which are independent of the severity of liver disease or HCV replication rates. Fatigue, sleep disturbance, depression and reduced quality of life are commonly associated with neurocognitive alterations in patients with non-cirrhotic chronic HCV infection, regardless of the stage of liver fibrosis and the infecting genotype. These manifestations, which are the topic of this review, typically occur in the absence of structural brain damage or signal abnormalities on conventional brain magnetic resonance imaging(MRI), although metabolic and microstructural changes can be detected by in vivo proton magnetic resonance spectroscopy, perfusion-weighted and diffusion tensorMRI, and neurophysiological tests of cognitive processing. Several lines of evidence, including comparative and longitudinal neuropsychological assessments in patients achieving spontaneous or treatment-induced viral clearance, support a major pathogenic role for HCV in neuropsychiatric and neurocognitive disorders.
