With the four components of a chemical heat pump (two solid-gas reactors, an evaporator and a condenser), a cycle of the double-effect type can be applied to continuous refrigeration. The performance of this process is analysed, allowing the infinite sink temperature and the couples of reactive salts to be used, which depend on the production temperature envisaged, to be selected. The results are ... [Show full abstract]Read more

To determine if reduced C9orf72 levels leads to glutamate receptor accumulation in vivo, we examined spinal motor neurons deleted of C9orf72 in Nestin-Cre-Stop-Flox-C9orf72 mice 22. Immunofluorescence analysis indicated that Nr1 (NMDA) and GluR1 (AMPA) levels were elevated in C9orf72-null motor neurons (Supplementary Fig. 12a, b). To confirm these findings, we isolated post-synaptic densities from the spinal cords of control and C9orf72 knockout mice. Post-synaptic density fractions contained glutamate receptors and PSD-95, but not p53 or synaptophysin, indicating they were enriched for post-synaptic density proteins (Supplementary Fig. 12c, 5i). Immunoblotting showed that post-synaptic densities in C9orf72 knockout mice contained significantly higher levels of Nr1 and Glur1 than in control mice (Fig. 4i, j and Supplementary Fig. 5j).
