Summary of Torsades de Pointes (TdP) Reports Associated with Intravenous Drug Formulations Containing the Preservative Chlorobutanol
ConclusionThe pharmacologic profile of chlorobutanol (synergistic IKR block) and its association with reports of TdP and QT prolongation suggest the need for a full evaluation of its cardiac safety when used as a preservative in IV drug and vitamin formulations.
Publication date: Available online 17 February 2020Source: Journal of Physics and Chemistry of SolidsAuthor(s): Laurens T. de Haan, Eser M. Akinoglu, Guofu ZhouAbstractA device consisting of a multidomain liquid crystal polymer network sandwiched between a continuous electrode and a perforated silver electrode shows strong surface deformations upon application of an electric field between the electrodes. Here, a new method is presented for the preparation of such a device, in which a silver film with circular holes of a well-controlled diameter was made by evaporating silver onto a monolayer of polystyrene spheres. Due to ...

VITAMIN D is essential for several reasons, including maintaining healthy bones and teeth. It may also protect against a range of diseases and conditions. Lacking in the vitamin could create a worrying sign that is often overlooked. What is it?
The traditional view of ventricular excitation and conduction is an all-or-nothing response mediated by a regenerative activation of the inward sodium channel, which gives rise to an essentially constant conduction velocity (CV). However, whereas there is no obvious biological need to tune-up ventricular conduction, the principal molecular components determining CV, such as sodium channels, inward-rectifier potassium channels, and gap junctional channels, are known targets of the “stress” protein kinases PKA and calcium/calmodulin dependent protein kinase II (CaMKII), and are thus regulatable by signal pathways...
