Thank you for inviting me to this Adv. ESCC 2022. It made me happy to participate. Oral communications were of good quality and interesting discussions and a fruitful exchange between participants. The participation in ESCC 2022 of researchers from different countries is very rewarding and allowed me to know people from different countries with which I intend to collaborate in the future to carry out scientific research. This is a strong point for this event. In this context, Peers Alley Media did a good job as a selection of the speakers and succeeded this mission of quality.Thank you so much.
