The impact of COVID-19 on international tourism flows to Italy: Evidence from mobile phone data.

This paper analyses the response to the COVID-19 pandemic of inbound tourism to Italy looking at variation across countries and provinces. To this end, it uses weekly data on the number of foreign visitors in Italy from January 2019 until February 2021, as provided by a primary mobile telephony operator. We document a very robust negative relation at the province level between the local epidemic situation and the inflow of foreign travellers.

Treatment of periocular wrinkles with topical nifedipine.

The appearance of facial expression wrinkles is the result of chronic contraction of mimic muscles. Nifedipine is a dihydropyridinic calcium antagonist which blocks muscular cells' calcium channels, therefore inhibiting their contraction. We assumed that topical nifedipine was able to relax mimic muscular fibres in the same way, thus reducing the depth of wrinkles.
