Pharmacokinetics of Nivolumab and Erythropoietin in a Rat Model of Diet-Induced Obesity.

Purpose: To investigate how obesity affects the pharmacokinetics of biologics in a rat model.

Method: Male Long-Evans rats were fed a high-fat diet from the age of 3 weeks and development of obesity was monitored by measuring body size and composition (fat and lean mass). The animals received nivolumab (1 and 8 mg/kg) or recombinant human erythropoietin (rHuEPO, 1000 IU/kg) by intravenous or subcutaneous injection.

Microstructure response of concentrated suspensions to flow reversal.

We study experimentally at the macroscopic and microstructure scale a dense suspension of non-Brownian neutrally buoyant spherical particles experiencing periodic reversals of flow at constant rate between parallel plates and tracked individually. We first characterize the quasi-steady state reached at the end of half periods. The volume fraction of particles increases from the walls to the center as a result of migration induced by the nonuniform strain rate.

One-Pot Synthesis of 2-Substituted Indoles and 7-Azaindoles Sequential Alkynylation and Cyclization of 2-Iodo--mesylarylamines and Alkynes in the Presence of CuO.

A one-pot process was developed to synthesize in moderate to high yield a series of 2-substituted indoles and 7-azaindoles starting from 2-iodo--mesylarylamines and terminal alkynes in the presence of CuO in DMF at 90-120 °C. Without isolation of any intermediate, our optimized conditions enabled the introduction of ester, phenyl, hydroxymethyl, hydroxyethyl, -Boc-aminomethyl, and methyl at the 2-postion of indoles and 7-azaindoles. The reaction tolerates a variety of substrates containing halogens, or acid- or base-sensitive functional groups without requiring a Pd catalyst, a ligand, or a base.
