Experimental Physiology, EarlyView.Abstract Proton (1H) magnetic resonance spectroscopy (MRS) is a non‐invasive imaging technique that can be used to assess brain metabolism. Establishing reference levels of fetal brain metabolites in a translatable preclinical model is crucial for identifying subtle deviations from normal cerebral development. Herein, we developed a 1H‐MRS protocol for

¹H NMR Chemical Shifts and J-Coupling Constants Dependence on Temperature and pH: Implications for the Quantification of Relevant Metabolites. [PDF]
NMR Biomed1H MRS, in combination with quantification methods using model functions based on prior knowledge of chemical shifts and coupling constants, allows the determination of characteristic metabolic processes in healthy and diseased tissue. Using the functional relationships δpHT$$ \delta \left( pH,T\right) $$ and JpHT$$ J\left( pH,T\right) $$ enables this ...

Simultaneous Detection of GABA and Glycine Using MEGA‐PRESS With TE Optimization at 3T
Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2479-2488, May 2026.ABSTRACT Purpose To achieve the simultaneous acquisition of gamma‐aminobutyric acid (GABA) and glycine (Gly) using a MEGA‐PRESS sequence with an optimized TE at 3T. Methods MEGA‐PRESS simulations were performed at TEs 60‐88 ms to determine the optimal TE for Gly detection with minimal myo‐Inositol (mI) overlap and maximal GABA detection sensitivity ...

AIChE Journal, Volume 72, Issue 4, April 2026.Abstract Air separation via selective adsorption using porous adsorbents offers energy‐efficient alternatives to cryogenic distillation for producing high‐purity O2 and N2. Adsorbent efficacy depends on balancing selectivity, durability, and performance consistency across varying conditions. This comprehensive review critically discusses the design and

Differentiating Creatine and Phosphocreatine In Vivo Using 3 T 1H MR Spectroscopy
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 1896-1906, April 2026.ABSTRACT Purpose Validation and improvements to the proton MR spectroscopic measurement of creatine and phosphocreatine in vivo at 3 T. Methods Spectral simulations were used to evaluate and explore the mitigation of LCModel fitting bias due to lineshape, signal‐to‐noise (SNR) and non‐metabolite backgrounds with a focus on phosphocreatine and the ...

Identifying Out‐of‐Voxel Echoes in Edited MRS With Phase Cycle Inversion
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 1921-1933, April 2026.ABSTRACT Purpose To identify the origin of out‐of‐voxel (OOV) signals based on the coherence transfer pathway (CTP) formalism using signal phase conferred by the acquisition phase cycling scheme. Knowing the CTP driving OOV artifacts enables optimization of crusher gradients to improve their suppression.
