Paralipomeni della disputa Bembo-Brocardo

Qualche anno fa mi capitò di editare una serie di sonetti vituperosi pertinenti alla “disputa Bembo-Brocardo” compresi nel Cod. Marc. It. XI 66(=6730). Di recente, scorrendo la versione elettronica della Rime del Brocardo, della quale la Biblioteca Italiana (BIT) attribuisce le cure a C[aterina] Saletti con la data del 2005, senza fare alcun riferimento a fonti o edizioni cartacee, mi è saltato agli occhi, proprio in coda al testo, con il numero d’ordine 47, il sonetto che trascrivo con qualc..

Microbiota and Oral Cancer as A Complex and Dynamic Microenvironment: A Narrative Review from Etiology to Prognosis

A complex balanced equilibrium of the bacterial ecosystems exists in the oral cavity that can be altered by tobacco smoking, psychological stressors, bad dietary habit, and chronic periodontitis. Oral dysbiosis can promote the onset and progression of oral squamous cell carcinoma (OSCC) through the release of toxins and bacterial metabolites, stimulating local and systemic inflammation, and altering the host immune response. During the process of carcinogenesis, the composition of the bacterial community changes qualitatively and quantitatively. Bacterial profiles are characterized by targeted sequencing of the 16S rRNA gene in tissue and saliva samples in patients with OSCC. Capnocytophaga gingivalis, Prevotella melaninogenica, Streptococcus mitis, Fusobacterium periodonticum, Prevotella tannerae, and Prevotella intermedia are the significantly increased bacteria in salivary samples. These have a potential diagnostic application to predict oral cancer through noninvasive salivary screenings. Oral lactic acid bacteria, which are commonly used as probiotic therapy against various disorders, are valuable adjuvants to improve the response to OSCC therapy
