    The disruption of proteostasis in neurodegenerative diseases

    Cells count on surveillance systems to monitor and protect the cellular proteome which, besides being highly heterogeneous, is constantly being challenged by intrinsic and environmental factors. In this context, the proteostasis network (PN) is essential to achieve a stable and functional proteome. Disruption of the PN is associated with aging and can lead to and/or potentiate the occurrence of many neurodegenerative diseases (ND). This not only emphasizes the importance of the PN in health span and aging but also how its modulation can be a potential target for intervention and treatment of human diseases.info:eu-repo/semantics/publishedVersio

    Pseudothermoosmosis in a Composite Membrane System

    The pseudothermoosmotic pressure of a composite membrane system, constituted by 2 cellulose (I) [9004-34-6] membranes and an aq. polyethylene glycol [25322-68-3], approached ∼6.0 × 105 dyn cm-2 which was higher than that measured with simple I membranes. The thermodn. of irreversible processes was used to derive the composite membrane phenomenol. equations contg. both the classical thermoosmosis and the thermal diffusion. A value of 3.91 kcal mol-1 was calcd. for the apparent activation energy, indicating the diffusive nature of the solvent flow through the composite membrane
