Glial Versus Neuronal Na+/K+‐ATPase in Activity‐Evoked K+ Clearance and Their Sensitivity to Elevated Extracellular K+

open access: yesGlia, EarlyView.
The glial Na+ pump regulates [K+]o during neuronal activity, and the neuronal version restores [K+]o to baseline. Spreading depression‐related rise of K+ does not cause SD propagation via suppression of Na+/K+‐ATPase or glutamate transport. ABSTRACT Neuronal activity in the central nervous system is associated with a [K+]o transient that is swiftly ...

Node Modification of Metal‐Organic Frameworks for Catalytic Applications

open access: yesChemistryOpen, EarlyView.
Post‐synthetic modification of metal‐organic framework (MOF) nodes with metal or organic species produces advanced materials that serve as efficient catalysts, promoting more sustainable chemical transformations. Abstract Metal‐organic frameworks (MOFs) have been a breakthrough in different fields of chemistry, not only due to the extensive ...

Engineering Pt Single‐Atom Doped SeS2/Ti3CNTx MXene with Molecularly Imprinted Polymer for Precision Pancreatic Cancer Diagnostics: DFT and Molecular Dynamics Perspectives

open access: yesSmall Methods, EarlyView.
A novel approach is developed to pancreatic cancer screening by targeting the cyclophili‐B (CypB)protein using a molecularly imprinted polymer with the electrode material containing Pt single‐atom‐doped/SeS2‐Ti3CNTx MXene. The quantification of CypB in pancreatic cancer tissues provide an insight into the association of CypB with pancreatic cancer ...

Quantification of Nitrite/Nitrate in Food Stuff Samples Using 2-Aminobenzoic Acid as a New Amine in Diazocoupling Reaction [PDF]

open access: yes, 2011
2-Aminobenzoic acid has been used as an amine in diazocoupling reaction to form an azo dye in the quantification of nitrite/nitrate at trace level. The formed azo dye has an absorption maximum at 550 nm in aqueous phase, and the resulted dye can be ...
