Extracellular Vesicles and Particles Modulate Proton Secretion in a Model of Human Parietal Cells.

The secretion of extracellular vesicles and particles (EVPs) is an important mechanism of cellular communication. In this work, we demonstrate a functional role of EVPs in mechanisms regulating gastric acid secretion. HGT-1 cells were used as a model system to assess proton secretion.

Thioglycolate-based task-specific ionic liquids: Metal extraction abilities vs acute algal toxicity.

We studied the extraction behavior of two thioglycolate-based ionic liquids (ILs), for heavy metals from aqueous solutions; substances of interest were methyltrioctylammonium S-hexyl thioglycolate [N][CSAc] and methyltrioctylphosphonium S-hexyl thioglycolate [P][CSAc]. Theses ILs previously have shown very good extraction abilities towards cadmium and copper, therefore we investigated time-dependent metal removal experiments with aqueous solutions of cobalt(II), nickel(II) and zinc(II). The highest distribution ratio (R) was determined for zinc (R=2000).
