Inter‐Individual Differences in T1, T2, and Proton Density Using Quantitative Synthetic Imaging for 1H‐MRS Quantification

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2489-2499, May 2026.
ABSTRACT Purpose Metabolite concentrations can be determined from proton magnetic resonance spectroscopy (1H‐MRS) data using water as an internal reference. This calculation requires tissue‐specific water T1 and T2 relaxation constants and proton density (PD).

Use of localized proton nuclear magnetic resonance spectroscopy in Canavan's disease

The Turkish Journal of Pediatrics, 1998
Canavan's disease is characterized by megalencephaly, leukodystrophy and early motor and mental retardation. On computerized tomography and magnetic resonance imaging, severe changes compatible with white matter disease due to demyelination is ...

New insights into the impact of neuro-inflammation in rheumatoid arthritis. [PDF]

, 2014
Rheumatoid arthritis (RA) is considered to be, in many respects, an archetypal autoimmune disease that causes activation of pro-inflammatory pathways resulting in joint and systemic inflammation.

Analyzing Nicotine Action Against Amyloid Toxicity by NMR‐Pharmacometabolomics: An Exploratory Study

NMR in Biomedicine, Volume 39, Issue 4, April 2026.
Combined metabolomic analysis of the intracellular and extracellular portions of SH‐SY5Y cells revealed that, in the presence of Aβ 1–42, nicotine primarily influences pathways related to neurotransmission, energy metabolism, as well as the biosynthesis and degradation of membrane phospholipids.

Dual association patterns between microglial activation and neuronal health in Alzheimer's disease: a whole‐brain MRSI/PET study

Alzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract INTRODUCTION Microglial activation can either support neuronal function or exacerbate damage, contributing to Alzheimer's disease (AD) progression. We investigated spatial relationships among microglial activation, neuronal health, and amyloid beta (Aβ) in the AD spectrum.

Characterizing Fatigue-Related White Matter Changes in MS: A Proton Magnetic Resonance Spectroscopy Study

Brain Sciences, 2019
Few cross-sectional studies have investigated the correlation between neurochemical changes and multiple sclerosis (MS) fatigue, but little is known on the fatigue-related white matter differences between time points.

Marine n‐3 Polyunsaturated Fatty Acids Mitigate Obesity Traits Through PRDM16‐Driven Gene–Nutrient Interaction and Spatiotemporal Scale Browning Process

Food Frontiers, Volume 7, Issue 2, March 2026.
This large cohort study of 45,664 participants from the UK Biobank provides strong epidemiological evidence that fish oil use was associated with 12% and 7% lower risks of obesity and high body fat percentage, respectively. Mechanistically, marine n‐3 polyunsaturated fatty acids mitigate obesity traits through PRDM16‐driven gene–nutrient interactions ...
