The probiotic Gram-positive bacterium Lactobacillus casei BL23 is naturally confronted with salt- stress habitats. It has been previously reported that growth in high-salt medium, containing 0.8 M NaCl, leads to modifica...

Silicon dioxide (SiO2), a material known as “silica” presents properties that make it a good candidate as a biomaterial: it has a very labile surface for functionalization, it is easy to synthesize and it is biocompa...

Microvertebrates are a major component of many assemblages recovered from the Quaternary of the Argentine Pampas. The main goal of this paper is to analyse the taphonomic history of a Holocene microfossil bonebed, recove...

Pharmaceuticals can exist in many solid forms, which can have different physical and chemical properties. These solid forms include polymorphs, solvates, amorphous, and hydrates. Particularly, hydration process can be qu...

We analysed the main plant strategies to conserve nitrogen in the Patagonian Monte. We hypothesized that the two main plant functional groups (xerophytic evergreen shrubs and mesophytic perennial grasses) display differe...

When biodiversity conservation of noncharismatic species is a priority, local people perception and value attributed to species are of vital importance. The big colony of bats (Tadarida brasiliensis) in the Escaba dam lo...
