Predictors of Early Death in Patients With Wild-Type Transthyretin Cardiac Amyloidosis.

Background: For the time being, tafamidis is the only approved treatment for wild-type transthyretin cardiac amyloidosis. However, benefits on all-cause death only emerge after ≈18 months. The current available staging systems are unable to specifically discriminate patients at high risk of death within 18 months from diagnosis, and the selection of patients who are expected to benefit from tafamidis is left to the clinical judgment of treating physicians, being often based primarily (and sometimes only) on age.

Unusual Reaction of Isocyanides with Aromatic Aldehydes Catalyzed by a Supramolecular Capsule.

The supramolecular resorcinarene hexameric capsule efficiently promotes the unprecedented reaction between isocyanides and electron-deficient aromatic aldehydes leading to the formation of imines and carbon monoxide. The mechanism of the reaction was investigated via isotope labelling, kinetic analysis of the reaction, computational studies and the independent synthesis of a proposed intermediate. Control experiments indicate that the formation of the key aziridinone intermediate is limited to the cavity of the capsule.

Botulinum Toxin Application for Treatment of Graft Vasospasm: A Reverse Translational Study.

Vascular graft vasospasm is a lethal risk when using grafts for revascularization and reconstructive surgery. Revascularization is a treatment modality for ischemic diseases including Moyamoya disease that requires bypass surgery. Cerebrovascular graft transplantation carries a 5-10% risk of vasospasm, which can lead to devastating neurological sequelae.

Isostructural Oxamate Complexes with Visible Luminescence (Eu) and Field-Induced Single-Molecule Magnet (Nd).

The search for new metal-organic compounds as candidates for quantum information processing technologies is in the spotlight. Several metal ions and organic linkers have been used to obtain such compounds. Herein, we describe the synthesis, crystal structures, and cryomagnetic properties of two air-stable isostructural neodymium(III) and europium(III) one-dimensional (1D) coordination polymers of formula [Nd(Hmpa)(DMSO)] (1) and [Eu(Hmpa)(DMSO)] (2) [Hmpa=N-(4-methylphenyl)oxamate, and DMSO=dimethylsulfoxide].
