We analyze to what extent the contribution of banks systemic risk depends on their centrality in financial networks. find that is an important determinant risk, but not primarily by its direct effect. Its main influence make other measures, such as probability default, more for highly connected banks. Neglecting indirect effect may severely underestimate or overestimate also show that, even tho...

Background: Drug-drug interactions (DDIs) may often lead to preventable adverse drug events and health damage. Particularly in hospitals, this might be an important factor as multiple drug therapies are common. The objective of this study was to identify the frequency and levels of potential DDIs in internal medicine wards in an Iranian university hospital. Methods: A cross-sectional study...

There has been increasing interest lately in understanding how natural dietary antioxidants affect chemoprevention, and recently, there has been a merging of information about antioxidants, endogenous and exogenous reactive oxygen and nitrogen species (RONS), and inflammation. RONS normally serve the cells as second messengers to regulate many of the intracellular signaling cascades that govern...

Economic interactions are represented as a functionally defined graph, and the existence of both cooperative and competitive business relations is taken into account. We provide an analytic solution of the model in a limit where the number of business relations of each company ...
