The Association of Niacin Use with Kidney Outcomes and Mortality.

Introduction: Niacin is a non-statin lipid-lowering therapy that has been shown to lower triglycerides and improve other risk factors for renal outcomes. Despite these favorable data, the effect of niacin on long-term kidney outcomes remains unclear. The aim of this study is to examine the associations of niacin therapies with incident chronic kidney disease (CKD), end-stage renal disease (ESRD), and death in patients with estimated glomerular filtration (eGFR) of at least 60 mL/min/1.

Strand-Swapped SH3 Domain Dimer with Superoxide Dismutase Activity.

The design of metalloproteins allows us to better understand metal complexation in proteins and the resulting function. In this study, we incorporated a Cu-binding site into a natural protein domain, the 58 amino acid c-Crk-SH3, to create a miniaturized superoxide dismutase model, termed SO1. The resulting low complexity metalloprotein was characterized for structure and function by circular dichroism and UV spectroscopy as well as EPR spectroscopy and X-ray crystallography.

Carbazole-Based Eu Complexes for Two-Photon Microscopy Imaging of Live Cells.

Lanthanide(III) complexes with two-photon absorbing antennas are attractive for microscopy imaging of live cells because they can be excited in the NIR. We describe the synthesis and luminescence and imaging properties of two Eu complexes, and , with (-carbazolyl)-aryl-alkynyl-picolinamide and (-carbazolyl)-aryl-picolinamide antennas, respectively, conjugated to the TAT cell-penetrating peptides. Contrary to what was previously observed with related Eu complexes with carbazole-based antennas in a mixture of water and organic solvents, these two complexes show very low emission quantum yield (Φ < 0.

DPYD genotype should be extended to rare variants: report on two cases of phenotype / genotype discrepancy.

The enzyme dihydropyrimidine dehydrogenase (DPD) is the primary catabolic pathway of fluoropyrimidines including 5 fluorouracil (5FU) and capecitabine. Cases of lethal toxicity have been reported in cancer patients with complete DPD deficiency receiving standard dose of 5FU or capecitabine. DPD is encoded by the pharmacogene DPYD in which more than 200 variants have been identified.
