Halogen bonding in metal–organic–supramolecular networks

Halogen bonding (XB) has been recently exploited as a significant tool for engineering crystals involving coordination and organometallic compounds as tectons. This review, in particular, focuses on extended networks based on XB between electron donor groups bound to metals and halo-pyridine and halotetrathiafulvalene moieties as electron acceptors. The influence of XB over the structures and the interactions between the organic frameworks and the metal centers is highlighted. The chemistry of some mononuclear systems forming XB is described in terms of tools for controlling supramolecular arrangement and chemical behaviour. Various computational studies on the energy of XB at different levels of sophistication, their advantages and limits concerning the evaluation of the interaction energy and modelling of its origin are critically surveyed. Modelling of a new example of interaction between Cp2MH2 (M= Mo, W) and CF3I is reported together with the description of the electron density of the complex analyzed in terms of the Quantum Theory of Atoms in Molecules (QTAIM) model

2017 ESC Guidelines for the management of acute myocardial infarction in patients presenting with ST-segment elevation: The Task Force for the management of acute myocardial infarction in patients presenting with ST-segment elevation of the European Society of Cardiology (ESC).

The ESC Guidelines represent the views of the ESC and were produced after careful consideration of the scientific and medical knowledge and the evidence available at the time of their publication. The ESC is not responsible in the event of any contradiction, discrepancy and/or ambiguity between the ESC Guidelines and any other official recommendations or guidelines issued by the relevant public health authorities, in particular in relation to good use of healthcare or therapeutic strategies. Health professionals are encouraged to take the ESC Guidelines fully into account when exercising their clinical judgment, as well as in the determination and the implementation of preventive, diagnostic or therapeutic medical strategies; however, the ESC Guidelines do not override, in any way whatsoever, the individual responsibility of health professionals to make appropriate and accurate decisions in consideration of each patient's health condition and in consultation with that patient and, where appropriate and/or necessary, the patient's caregiver. Nor do the ESC Guidelines exempt health professionals from taking into full and careful consideration the relevant official updated recommendations or guidelines issued by the competent public health authorities, in order to manage each patient's case in light of the scientifically accepted data pursuant to their respective ethical and professional obligations. It is also the health professional's responsibility to verify the applicable rules and regulations relating to drugs and medical devices at the time of prescription
