Simultaneous production of nitric oxide and peroxynitrite by plant nitrate reductase: in vitro evidence for the NR-dependent formation of active nitrogen species [PDF]

open access: yes, 2000
We examined the ability of plant nitrate reductase (NR) to produce nitric oxide (NO) using in vitro assays. Electrochemical and fluorometric measurements both showed that NO is produced by corn NR in the presence of nitrite and NADH at pH 7.

Enhancing the Pharmacokinetics of Aptamers: Targeting AXL In Vivo Using a Bottlebrush Polymer‐Conjugated Aptamer

open access: yesAdvanced Healthcare Materials, EarlyView.
A phosphodiester‐backboned bottlebrush polymer (pacDNA) engineered for aptamer delivery is presented. This design enhances aptamer stability, plasma pharmacokinetics, and target engagement in vivo. In AXL‐driven cancer models, pacDNA inhibits AXL signaling and reduces tumor growth, highlighting the promise of precision polymer scaffolds in aptamer ...

Proton MR Spectroscopy of Neural Stem Cells: Does the Proton-NMR Peak at 1.28 ppm Function As a Biomarker for Cell Type or State? [PDF]

open access: yes, 2011
Recently, a peak at 1.28 ppm in proton magnetic resonance spectroscopy (^1H-MRS) of neural stem cells (NSCs) was introduced as a noninterventional biomarker for neurogenesis in vivo. This would be an urgently needed requisite for translational studies in
