G protein–coupled receptors (GPCRs), including olfactory receptors, account for the largest group of genes in the human genome and occupy a very important position in signaling systems. Although olfactory receptors, which belong to the broader category of GPCRs, play an important role in monitoring the organism's surroundings, their actual three-dimensional structure has not yet been determined. Therefore, the specific details of the molecular interactions between the receptor and the ligand remain unclear. In this report, the interactions between human olfactory receptor 1A1 and its odorant molecules were simulated using computational methods, and we explored how the chemically simple odorant molecules activate the olfactory receptor.

Background: The aim of this study was to report the effect of acupotomy for patients with headache. Methods: Four patients with headache were treated with acupotomy. The improvement of symptoms was evaluated by numeric rating scale(NRS), Headache impact test-6(HIT-6) and headache attack frequency. Results: The numeric rating scale score and headache attack frequency decreased throughout the treatment period. No side effects were observed during treatment. Conclusion: Acupotomy had shown a positive clinical effect in the treatment of a headache in this case series. Further studies are required for its application on various headache.
