Financial regulation has shifted from a system as an oligopoly dominated by the G2/G5 to expanded clubs like the Basel Committee for Banking Supervision. Expansive clubs have to agree to terms that are closer to the preferences of soft-regulation members. Yet, once a global agreement on minimum standards, such as Basel 3, is reached, the task is left to national or regional regulators. Deviations from the Basel 3 standards are bound to occur; the complexity of the agreement will facilitate an asymmetric implementation of national regulation and supervision. Countries like Australia, Canada, the United Kingdom, the United States, and some Scandinavian countries have chosen higher standards. On the other hand, we should expect deviations to take place in member countries of the Eurozone that are heterogeneous having different preferences and trade-off between regulatory stringency and economic activity. The requirements of both global clubs and regional club regarding transparency, monitoring, and a level playing field will also cause a collision. This paper reports examples of heterogenous applications of supervisions and reforms.

We studied the polyphenol composition and antioxidant activity of the ethanolic and ethyl acetate extracts of Hypericum connatum (Guttiferae), in addition to their antimicrobial and antiquorum-sensing (AQS) properties. The extracts exhibited a similar polyphenol content and a notable antioxidant activity, which was stronger in the ethanolic extract (EC50=3.2 μg/mL). Ultrahigh-performance liquid chromatography analyses revealed different polyphenol profiles, with rutin and apigen being the main components of the ethanolic extract and caffeic acid, (–)-epicatechin and p-coumaric acid being abundant in the ethyl acetate extract. The ethyl acetate extract exhibited a more effective antimicrobial activity than the ethanolic extract against the pathogens Staphylococcus aureus, Bacillus cereus, Escherichia coli, and Pseudomonas aeruginosa. For the first time, AQS activity was detected in H. connatum: the ethanolic extract inhibited the production of violacein, a quorum-sensing–regulated pigment, in a Chromobacterium violaceum tester strain, without interfering with its growth.

This study investigated the phenolic composition and antioxidant capacity of an ethanolic extract from the peel of the Annurca (Malus domestica var. Annurca), which is widespread in the Campania region of southern Italy. The antimicrobial effect of the extract on different pathogens was also examined. The potential antiquorum sensing activity of the extract was tested by using the microorganism Chromobacterium violaceum. Ultra-performance liquid chromatography revealed that rutin, epicatechin, dicaffeoylquinic acid, and caffeic acid were the most abundant phenolic compounds in the extract; these compounds constituted 27.43%, 24.93%, 16.14%, and 15.3% of the total phenols, respectively. The test for 2,2-diphenyl-1-picryl-hydrazyl free radical–scavenging activity showed that the extract possessed an impressive antioxidant capacity (50% effective concentration of 2.50 μg/g of product). Furthermore, the extract clearly exhibited antimicrobial activity against Bacillus cereus (11- to 14-mm diameter of inhibition halo, depending on the strain) and Escherichia coli serotype O157:H7 (10-mm diameter of inhibition halo). No activity was observed against the probiotic lactobacilli tested or against Staphylococcus aureus. Antiquorum sensing activity was reported for the first time for apple extracts. In conclusion, these results indicate the potential of this extract for treating some microbial infections through cell growth inhibition or quorum sensing antagonism, thereby validating the health benefits of apples.

Our work aimed to investigate the phenolic composition and antioxidant capacity of the de-alcoholized extract of cider obtained from the Annurca apple (Malus domestica var. Annurca). The antimicrobial effect of the extract against different pathogens, including Chronobacter sakazakii, was also examined. The extract’s potential anti-quorum-sensing (AQS) activity was assessed using the test microorganism Chromobacterium violaceum. Biochemical analysis of the extract using ultra-performance liquid chromatography revealed catechin and caffeic acid as the most abundant polyphenols present,which represented about 35.5% and 36.6% of the total phenolics identified, respectively. An antioxidant capacity was also found (50% effective concentraiton = 10 lL). The extract exhibited clear antimicrobial activity against all strains used in the experiments. Escherichia coli and Bacillus cereus were the most sensitive bacteria to the antimicrobial activity. The extract also inhibited the growth of the emergent pathogen strain C. sakazakii. The AQS activity of apple cider is reported here for the first time. In conclusion, our results demonstrate some biological properties of the apple cider and contribute to reinforcing the potential of the apple and its derivatives as functional components of the diet.

Extracts of the bulbs of the two endemic varieties “Rosato” and “Caposele” of Allium sativum of the Campania region, Southern Italy, were analyzed. The phenolic content, ascorbic acid, allicin content, and in vitro antimicrobial and antifungal activity were determined. Ultra performance liquid chromatography with diode array detector performed polyphenol profile. The polyphenolic extracts showed antioxidant activity (EC50) lower than 120 mg. The amount of ascorbic acid and allicin in the two extracts was similar. Polyphenol extract exhibited antimicrobial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and (only by the extract of Rosato) against Bacillus cereus. The extract of Caposele was more effective in inhibiting the growth of Aspergillus versicolor and Penicillum citrinum. On the other hand, the extract of Rosato was effective against Penicillium expansum.
