In-vivo protein nitration and de-nitration facilitate Vibrio cholerae cell survival under anaerobic condition: Consequences of Nitrite induced protein nitration

open access: yes, 2021
Protein tyrosine nitration (PTN), a highly selective post translational modification, occurs in both prokaryotic and eukaryotic cells under nitrosative stress1. It is reported that the activities of many proteins are altered due to PTN2.

Tailored Hierarchical Porous Copper Architectures via Three Dimensional Printing and Pressure‐less Sintering for Next‐Generation Lithium‐Metal Batteries

open access: yesAdvanced Engineering Materials, EarlyView.
A hierarchical porous copper current collector is fabricated via three‐dimensional printing combined with pressureless sintering to stabilize lithium metal anodes. The interconnected architecture lowers local current density, guides uniform Li deposition within pores, and suppresses dendrite growth.

Incorporation of Selenium into Sol–Gel‐Derived Bioactive Glass: Influence on Glass Structure, Bioactivity, and its Selective Cytotoxicity

open access: yesAdvanced Engineering Materials, EarlyView.
Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

Gearing of nitrate ions in ammonium nitrate

open access: yesThe Journal of Chemical Physics
Reorienting polyatomic ions such as NH4+ and NO3− exhibit weak magnetic fields because the ions at the extremities trace out current loops; if the periodic reorientations become long-range ordered (i.e., gearing of neighboring NO3−), then the magnetic susceptibility should exhibit a unique signature along the different crystallographic axes.

Nitrates for achalasia [PDF]

open access: yesCochrane Database of Systematic Reviews, 2002
Achalasia is a disease that impairs oesophageal motility. Though nitrates have been used to treat achalasia for a long time, the effectiveness of nitrates for achalasia is still controversial.To quantify short-term and long-term effects of nitrate therapy in patients with achalasia.Trials were identified by searching the Cochrane Controlled Trials ...
