- ... Biodiversity is not uniformly distributed on earth, with sites more relevant than others, due to their intrinsic properties or their evolutionary and/or biogeographical context. The tropical Andes are globally acknowledged for their importance for preserving high biodiversity and endemism, and at the same time by the high level of anthropogenic pressure. In this study, we assessed the subtribe Pro ...

- ... The increase in the intracellular Ca2+ concentration ([Ca2+]i) is the key variable for many different processes, ranging from regulation of cell proliferation to apoptosis. In this work we demonstrated that the sphingolipid sphingosine (Sph) increases the [Ca2+]i by inhibiting the sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA), in a similar manner to thapsigargin (Tg), a specific inhibitor of th ...

- ... Proteus mirabilis is a human pathogen able to form biofilms on the surface of urinary catheters. Little is known about P. mirabilis biofilms on natural or industrial surfaces and the potential consequences for these settings. The main aim of this work was to assess and compare the adhesion and biofilm formation of P. mirabilis strains from different origins on chitin and stainless steel surfaces w ...
