Validity of Serum Sodium and Calcium Screening in Children [PDF]

open access: yesActa Medica Iranica, 2009
Febrile convulsion (FC) is the most common seizure disorder in young children. Different predisposing factors have been suggested to enhance the susceptibility to febrile seizure and its recurrence.

Rician Denoising Diffusion Probabilistic Models For Sodium Breast MRI Enhancement [PDF]

open access: yesarXiv
Sodium MRI is an imaging technique used to visualize and quantify sodium concentrations in vivo, playing a role in many biological processes and potentially aiding in breast cancer characterization. Sodium MRI, however, suffers from inherently low signal-to-noise ratios (SNR) and spatial resolution, compared with conventional proton MRI.

Superdielectric Materials Composed of Sodium Chloride, Water and Porous Alumina [PDF]

open access: yesarXiv, 2014
Superdielectric behavior was observed in pastes made of high surface area alumina filled to the level of incipient wetness with water containing dissolved sodium chloride (table salt). In some cases the dielectric constants were greater than 10^10.

Theoretical Studies on Sodium Storage Mechanism in Hard Carbon Anodes of Sodium-Ion Batteries: Molecular Simulations Based on Machine Learning Force Fields [PDF]

open access: yesarXiv
Sodium-ion batteries (SIBs) have garnered significant attention in recent years as a promising alternative to lithium-ion batteries (LIBs) due to their low cost, abundant sodium resources, and excellent cycling performance. Hard carbon materials, characterized by their high specific capacity, outstanding cycling stability, and low cost, have emerged as

Multi-TE Single-Quantum Sodium (23Na) MRI: A Clinically Translatable Technique for Separation of Mono- and Bi-T2 Sodium Signals [PDF]

open access: yesarXiv
Sodium magnetic resonance imaging (MRI) is sensitive and specific to ionic balance of cells owing to 10 fold difference in sodium concentration across membrane actively maintained by sodium potassium (Na+ K+) pump. Disruption of the pump and membrane integrity, as seen in neurological disorders such as epilepsy, multiple sclerosis, bipolar disease, and
