2015/8/13· A myriad of studies have argued that tactile sensibility is underpinned exclusively by large myelinated mechanoreceptors. However, the functional significance of their slow-conducting counterparts, termed C-low threshold mechanoreceptors (C-LTMRs), remains largely unexplored. We recently showed the emergence of brush- and vibration-evoked allodynia in human hairy and glabrous …

Soil bacteria that precipitate calcium carbonate: …

Calcium carbonate precipitation mechanism Urease alyzes urea hydrolysis to produce ammonium and carbonate. In this reaction, one mole of urea is hydrolyzed and forms one mole of ammonium and one mole of carbamic acid (), which is hydrolyzed spontaneously to another ammonium and carbonic acid molecule (Hammes et al., 2003a; Li et al., 2000; Stocks-Fischer et al., 1999b), which are balanced
