Zerumbone has shown great potential in various pathophysiological models of diseases, particularly in neuropathic pain conditions. Further understanding the mechanisms of action is important to develop zerumbone as a potential anti-nociceptive agent. Numerous receptors and pathways function to inhibit and...

Dravet syndrome (DS) is a childhood epilepsy syndrome caused by heterozygous mutations in the SCN1A gene encoding voltage-gated sodium channel Nav1.1. We generated iPSCs from fibroblasts of three DS patients carrying distinct SCN1A mutations (c.5502-5509dupGCTTGAAC, c.2965G>C and c.651C>G). The iPSC...

The mica-based glass-ceramics were prepared in the SiO2-Al2O3-MgO-MgF2-SrCO3-CaCO3-CaF2-P2O5 glass system. There were four mica-based glass-ceramics produced in this study according to the pigment added (CeO2 or Pr-ZrSiO4/Fe-ZrSiO4) and crystallization time (5-35 min). Four dental glass-ceramics, which were leucite-based, lithium disilicate-based...

Cicada flowers, which are edible and medicinal mushrooms, are the fruiting bodies of Isaria cicadae, a fungus that is parasitic on the larvae of cicada pupae. We hypothesize that host factors might possess stimulatory activity on metabolite synthesis in Isaria...
The synthesis of heteroaromatic and aromatic compounds is at the heart of the chemical industry. The ever-growing demand for new chemical entities, coupled with dwindling resources and time constraints allotted to any given research project, a rapid way to diversify (hetero)aromatic scaffolds is needed.
