Hepatocyte pyroptosis and release of inflammasome particles induce stellate cell activation and liver fibrosis.
2019
Background & Aims Increased hepatocyte death contributes to the pathology of acute and chronic liver diseases. However, the role of hepatocyte pyroptosis and extracellular inflammasome release in liver disease is unknown. Methods We used primary mouse and human hepatocytes, hepatocyte-specific leucine 351 to proline Nlrp3KICreA mice, and GsdmdKO mice to investigate pyroptotic cell death in hepatocytes and its impact on liver inflammation and damage. Extracellular NOD-, LRR-, and pyrin domain-containing protein 3 (NLRP3) inflammasomes were isolated from mutant NLRP3-YFP HEK cells and internalisation was studied in LX2 and primary human hepatic stellate cells. We also examined a cohort of 154…
Newtonian and relativistic location systems
2008
The theory of location systems involves the geometric and physical description of the protocols allowing the realization of coordinate systems. In this communication, the incidence of the space-time causal structure (Newtonian or relativistic) on the construction of location systems is remarked. Specifically, we focus our attention: (i) on the construction of Newtonian emission coordinates that are contrasted with those associated with relativistic positioning systems, and (ii) on the role played by non-absolute synchronizations (like the one provided by the local Solar time) in the comprehension of Newtonian and relativistic location systems.
A Real time locating system for local fleet management
2006
Abstract Local locating systems are necessary where a big number of units are handled. In this case, we propose a management system for parking spaces for vehicles that are distributed among eight different-sized lots on a 1.8 million square meter premises. In order to quickly locate each particular vehicle in this area, a new real time location system (RTLS) has been successfully installed. The vehicle location system Moby-R automatically monitors every vehicle movement and tracks its current parked position. All the vehicles are given a data carrier which is attached to the inside rear-view mirror with a special hanger, precisely locating the vehicle within approximately five meters
