This study analyses potential consequences of exiting the Targeted Long-Term Refinancing Operations (TLTRO) of the European Central Bank (ECB). Thanks to its asset purchase programs, the Eurosystem still holds plenty of reserves even with a full exit from the TLTROs. This explains why voluntary and mandatory repayments of TLTRO III borrowing went smoothly. Nevertheless, the more liquidity is drained from the banking system, the more important becomes interbank market borrowing and lending, ideally between euro area member states. Right now, the usual fault lines of the euro area show up. The German banking system has plenty of reserves while there are first signs of aggregate scarcity in the Italian banking system. This does not need to be a source of concern if the interbank market can be sufficiently reactivated. Moreover, the ECB has several tools to address possible future liquidity shortages.

The little-known Roman gold mining site "Gralheira" is located near the well-explored mine of Tresminas. The 2.5 km long, almost dead straight archaeological monument from the first and second centuries AD is currently under threat from possible mining activities on the one hand and from modern waste disposal in the pits on the other. Since 2019, the Roman mining traces have been investigated by means of intensive field inspections, terrestrial 3d laser scanning and aerial photography. The following article will present first impressions and findings on this structure, as well as questions and preliminary interpretations.
The remains of the ancient Roman town, crossed by the Flaminia road and lapped by a bend of the Tiber, are located in a natural landscape of significant beauty, perfect synthesis of archaeology and nature that remained unchanged throughout centuries. Excavations were conducted here from a very early period, especially from 1776 to 1784, when a great quantity of material was removed. The archaeological excavations carried out in Otricoli in the second half of the Seventeenth century together with discoveries in Herculaneum, Pompeii, Stabiae and other cities of ancient Italy, contributed during the Neoclassical period to the rediscovery of classical ideals in art and architecture, partly already rediscovered during Humanism and the Renaissance in Italy.
Die vorliegende Studie beschäftigt sich mit der Konstituierung von amicitia im Mythos und fragt nach der Erzählung als Gabe im amikalen Gabentauschzyklus. Die Hinweise auf amicitia als eine der zentralen Bindungstypen des römischen Gemeinwesens sind über verschiedene Werke verstreut, lassen aber bereits die Wirkkraft erahnen, weil sie rückblickend in die Frühzeit hineingeschrieben wurden. In diesem Zusammenhang wird auch die Bedeutung der Erzählung als Gabe im Gabentauschzyklus untersucht, da diese die Transformation vom Fremden zum Anderen ermöglichen kann; erst auf diese Weise wird eine Grundlage für amicitia geschaffen. Darüber hinaus gelingt erst in der Urvergangenheit des Mythos’ die Perpetuierung von amicitia und dem sie konstituierenden amikalen Gabentausch.
Endogenous nitro-fatty acids (NFA) are potent electrophilic lipid mediators that exert biological effects in vitro and in vivo via selective covalent modification of thiol-containing target proteins. The cytoprotective, anti-inflammatory, and anti-tumorigenic effects of NFA in animal models of disease caused by targeted protein nitroalkylation are a valuable basis for the development of future anti-phlogistic and anti-neoplastic drugs. Considering the complexity of diseases and accompanying comorbidities there is an urgent need for clinically effective multifunctional drugs. NFA are composed of a fatty acid backbone containing a nitroalkene moiety triggering Michael addition reactions. However, less is known about the target-specific structure–activity relationships and selectivities comparing different NFA targets. Therefore, we analyzed 15 NFA derivatives and compared them with the lead structure 9-nitro-oleic acid (9NOA) in terms of their effect on NF-κB (nuclear factor kappa B) signaling inhibition, induction of Nrf-2 (nuclear factor erythroid 2-related factor 2) gene expression, sEH (soluble epoxide hydrolase), LO (lipoxygenase), and COX-2 (cyclooxygenase-2) inhibition, and their cytotoxic effects on colorectal cancer cells. Minor modifications of the Michael acceptor position and variation of the chain length led to drugs showing increased target preference or enhanced multi-targeting, partly with higher potency than 9NOA. This study is a significant step forward to better understanding the biology of NFA and their enormous potential as scaffolds for designing future anti-inflammatory drugs.
The complex and adaptive nature of malignant neoplasm constitute a major challenge for the development of effective anti-oncogenic therapies. Emerging evidence has uncovered the pivotal functions exerted by the small leucine-rich proteoglycans, decorin and biglycan, in affecting tumor growth and progression. In their soluble forms, decorin and biglycan act as powerful signaling molecules. By receptor-mediated signal transduction, both proteoglycans modulate key processes vital for tumor initiation and progression, such as autophagy, inflammation, cell-cycle, apoptosis, and angiogenesis. Despite of their structural homology, these two proteoglycans interact with distinct cell surface receptors and thus modulate distinct signaling pathways that ultimately affect cancer development. In this review, we summarize growing evidence for the complex roles of decorin and biglycan signaling in tumor biology and address potential novel therapeutic implications.
