Synthesis and characterization of isostructural annulated actinocenes.

An isostructural series of four annulated actinocene complexes, M(hdcCOT) (M = Th, U, Np, Pu), is reported. The syntheses proceed through a trivalent starting material when M = U, Np, Pu with subsequent oxidation or, in the case of M = Th, directly from ThCl(DME). X-ray crystallography shows that each actinocene has molecular point symmetry in the solid state, with the metal atoms symmetrically bonded to two 10π-aromatic [8]annulene dianion rings.

Crystal structure of cytochrome P450 NysL and the structural basis for stereo- and regio- selective oxidation of antifungal macrolides.

NysL, a cytochrome P450 monooxygenase from the Gram-positive bacterium Streptomyces noursei, catalyzes the C10 hydroxylation of 10-deoxynystain to nystatin A, a clinically important antifungal. In this study, we present the 2.0 Å resolution crystal structure of NysL bound to nystatin A.

Influences on safety of intrapartum electronic fetal heart rate monitoring practices: a scoping review.

Objectives: Suboptimal intrapartum electronic fetal heart rate monitoring using cardiotocography has remained a persistent problem (EFM-CTG). We aimed to identify the range of influences on the safety of using EFM-CTG in practice.

Design: Scoping review to identify influences related to the practice of intrapartum EFM.

Therapeutic development to accelerate malaria control through intentional intervention layering.

The clinical development of novel vaccines, injectable therapeutics, and oral chemoprevention drugs has the potential to deliver significant advancements in the prevention of Plasmodium falciparum malaria. These innovations could support regions in accelerating malaria control, transforming existing intervention packages by supplementing interventions with imperfect effectiveness or offering an entirely new tool. However, to layer new medical tools as part of an existing programme, malaria researchers must come to an agreement on the gaps that currently limit the effectiveness of medical interventions for moderate to low transmission settings.
