Here we show a general approach to achieve dissipative control over toehold-mediated strand-displacement, the most widely employed reaction in field of DNA nanotechnology. The relies on rationally re-engineering classic strand displacement such that high-energy invader (fuel) is converted into low-energy waste product through an energy-dissipating allowing spontaneous return original state time...

According to the US Food and Drug Administration's (FDA's) regulations, the criteria used to select patients into registration studies should be addressed in a product's label. The FDA's labelling guidelines, which specifically indicate that the routine exclusion of patients of a certain level of severity should be noted in the label, has been uniformly ignored.

OBJECTIVES/PURPOSE To review Patient Reported Outcome (PRO) labelling claims achieved in oncology in Europe and in the United States and consider the benefits, and challenges faced. METHODS PROLabels database was searched to identify oncology products with PRO labelling approved in Europe since 1995 or in the United States since 1998. The US Food and Drug Administration (FDA) and the European...

Assays that attempt to characterize HIV susceptibility or resistance are among the latest technologies that are likely to impact HIV clinical trial design, antiretroviral drug development and patient management. However, at present the Food and Drug Administration (FDA) have yet to approve any phenotypic or genotypic HIV resistance assay and the role of resistance testing in clinical management...

In October 2021, twenty-one OECD countries and partner economies participated in an online product safety sweep to identify the degree which products were available for sale despite (i) being banned or recalled, (ii) having inadequate labelling (iii) not meeting voluntary mandatory standards. Results reveal that large volumes of unsafe are readily traded across borders a 79% average rate non-co...

Current drugs to treat African sleeping sickness are inadequate and new therapies are urgently required. As part of a medicinal chemistry programme based upon the simplification of acetogenin-type ether scaffolds, we previously reported the promising trypanocidal activity of compound 1, a bis-tetrahydropyran 1,4-triazole (B-THP-T) inhibitor. This study aims to identify the protein target(s) of ...

AIMS Dexmedetomidine (dexdor®) is approved in the European Union (EU) for sedation of adults in the intensive care unit (ICU). The present observational, retrospective study was requested by the European Medicines Agency to investigate dexmedetomidine use in clinical practice, with a particular focus on off-label use, including the paediatric population. METHODS Study countries and sites were...

BACKGROUND The increase in sales of nutritional supplement globally can be attributed, in part, to aggressive marketing by manufacturers, rather than because the nutritional supplements have become more effective. Furthermore, the accuracy of the labelling often goes unchallenged. Therefore, any effects of the supplement, may be due to contaminants or adulterants in these products not reflected...

Cigarette on-pack messages are one of the principal vehicles for informing smokers about the risks of smoking and research has highlighted their role as a valid health communication tool. Furthermore, they have the potential to disrupt the powerful cigarette brand imagery associated with tobacco packaging. Responding to concerns within Europe that the old style on-pack messages were ineffective...
