We study the vulnerability of 130 banks directly supervised by the European Central Bank’s Single Supervisory Mechanism. Illustrative stress tests using banks’ balance sheet data reveal that significant stress prevails in the euro area’s smaller and medium-sized banks, many of them located in southern Europe. The banks we identify as stressed also have performed substantially worse on the stock market. The vulnerable banks are typically hobbled by non-performing loans to European businesses. Strengthening the banking system, therefore, is important to achieve sustainable recovery because it will revitalise credit to the healthier segments of the economy. But instead of emphasising bank recapitalisation, as in past years, we believe the task is to shrink the banking sector to a healthier core.

BACKGROUND Nociceptin in the peripheral circulation has been proposed to have an immunoregulatory role with regards to inflammation and pain. However, the mechanisms involved in its regulation are still not clear. The aim of this study was to investigate signalling pathways contributing to the regulation of the expression of nociceptin under inflammatory conditions. METHODS Mono Mac 6 cells (MM6) were cultured with or without phorbol-12-myristate-13-acetate (PMA). Prepronociceptin (ppNOC) mRNA was detected by RT-qPCR and extracellular nociceptin by fluorescent-enzyme immunoassay. Intracellular nociceptin and phosphorylated kinases were measured using flow cytometry. To evaluate the contribution of various signalling pathways to the regulation of ppNOC mRNA and nociceptin protein, cells were pre-treated with specific kinase inhibitors before co-culturing with PMA. RESULTS ppNOC mRNA was expressed in untreated MM6 at low concentrations. Exposure of cells to PMA upregulated ppNOC after nine h compared with controls without PMA (median normalized ratio with IQR: 0.18 (0.15-0.26) vs. 0 (0-0.02), P<0.01). Inhibition of mitogen-activated protein kinases specific for signal transduction reversed the PMA effects (all P<0.001). Induction of nociceptin protein concentrations in PMA stimulated MM6 was prevented predominantly by identity of ERK inhibitor (P<0.05). CONCLUSIONS Upregulation of nociceptin expression by PMA in MM6 cells involves several pathways. Underlying mechanisms involved in nociceptin expression may lead to new insights in the treatment of pain and inflammatory diseases.

The interval between 488.2 and 513.7 m below seafloor at Deep Sea Drilling Project (DSDP) Site 615 is interpreted as a single carbonate gravity-flow deposit. The deposit has characteristics of both a debris flow and a high-density turbidity current. Comparison of the sedimentary constituents in 15 samples from this site with samples from 26 core tops from the upper West Florida continental slope and eastern Mississippi Fan shows many similarities. Shallow-water indicators, such as mollusk and echinoid fragments, occur in both suites of samples. The West Florida continental margin, therefore, is a potential provenance area. The Yucatan slope is also a possible source, but data from it are limited. The recognition of carbonate gravity-flow deposits intercalated within the Mississippi Fan refines our understanding of Pleistocene sedimentation within the Gulf basin. Deposition in the deep Gulf is dominated by the construction of the Mississippi Fan. However, this marine terrigenous depocenter is located between two large carbonate depocenters, the West Florida continental margin on the east and the Yucatan peninsula on the southwest. Periodically, the carbonate slope in these two regions fails, injecting carbonate gravity flows into the accreting terrigenous deep-sea fan.
