[Screening for atrial fibrillation in the general population: experience from a cardiovascular risk campaign in the Emilia-Romagna Region].

Background: Atrial fibrillation (AF) is a major cause of cerebral ischemia, and its early detection may impact on health. Both invasive and non-invasive devices can be used for the diagnosis of AF. The aim of our study was to estimate the prevalence of AF using a single-lead ECG device (MyDiagnostickTM) on an adult, asymptomatic population during a screening campaign.

Naphthoquinones inhibit formation and viability of Yersinia enterocolitica biofilm.

The capacity of different naphthoquinones to inhibit and eradicate Yersinia enterocolitica biofilm was investigated and possible mechanisms of action were evaluated. Inhibition of biofilm formation and cell viability, quorum sensing (QS) inhibition and oxidative stress generation of 23 naphthoquinones were assayed against Yersinia enterocolitica. The best anti-biofilm agents at 100 µmol l were compounds 3, 11 and 13, which showed biofilm inhibition higher than 75%.

Aporphinoid alkaloids inhibit biofilm formation of Yersinia enterocolitica isolated from sausages.

Aims Of The Study: The ability of Yersinia enterocolitica strains to form biofilms and the capacity of different alkaloids to inhibit biofilm formation were investigated.

Methods And Results: The capacity to form biofilm on polystyrene of 31 Y. enterocolitica strains was evaluated.
