In addition, essential oil was extracted from fresh leaves (PM-EO) collected in dry and rainy seasons to investigate the influence of seasonality and, after that, to evaluate its antifungal activity on mycelial growth of Colletotrichum gloeosporioides. Both GC-FID and GC-MS analyses revealed that major components determined in PM-EO were β-caryophyllene (20.0% and 32.9%) and limonene (10.4% and 19.8%) in rainy and dry seasons, respectively. High antioxidant capacity was displayed by unripe fruit (IC50 = 3.57 mg/mL) and ripe ones (IC50 = 3.68 mg/mL). Both showed high total phenolic and tannin contents. In sum, PM-EO showed satisfactory antifungal activity, since its inhibitory action on mycelial growth of C. gloeosporioides was above 70% in the dry season, while it exhibited weak activity in the rainy season.This invited editorial comments on the article 'Ettore's Song'.Introduction The coronavirus disease 2019 (COVID-19) pandemic, caused by a newly discovered coronavirus (severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2), continues to spread all around the world. Despite the emergency of COVID-19 worldwide, remdesivir is the only treatment that has been recently approved to treat the diseases, and other effective therapies are still lacking. SARS-CoV-2 may cause severe illness in 20% of patients. Based on available data, there is an association between interleukin-6 (IL-6) and severe COVID-19. Sarilumab is a fully human immunoglobulin G1 monoclonal antibody binding to both membrane-bound and soluble IL-6 receptors with high affinity and has been considered for off-label use in the treatment of COVID-19. Areas covered The present article reviews recently published literature focusing on the pathophysiology of COVID-19 induced cytokine storm, the pot
