Abstract:
Glaucoma is a disease that is chronic in nature and indistinctive at an early stage, leading to late detection. It has become a major public health problem and a leading cause of irreversible blindness worldwide. The proton magnetic resonance spectroscopy (1H-MRS), of late, has been utilised to evaluate metabolites concentration in the brain, especially for detecting neurodegenerative disease. Considering that glaucoma is a neurodegenerative disease, studies on the concentration of metabolites using 1H-MRS in glaucoma patients could be investigated. This scoping review aims to examine the exte

Abstract:
Magnetic resonance spectroscopy (MRS) is a noninvasive technique for measuring metabolite concentration. It can be used for preclinical small animal brain studies using rodents to provide information about neurodegenerative diseases and metabolic disorders. However, data acquisition from small volumes in a limited scan time is technically challenging due to its inherently low sensitivity. To mitigate this problem, this study investigated the feasibility of a low-rank denoising method in enhancing the quality of single voxel multinuclei (31P and 1H) MRS data at 9.4 T. Performance was evaluated

Abstract:
Abstract IDH mutation, a key factor in predicting glioma prognosis, alters the levels of some metabolites in brain, including 2-hydroxyglutarate (2HG), glutamine (Gln), and glutathione (GSH). While proton MR spectroscopy (1H-MRS) enables in-vivo detection of these metabolites, liquid chromatography-mass spectrometry (LC-MS/MS) is a sensitive in-vitro method to measure absolute metabolite concentrations. This study aims to examine the correlation of metabolic concentrations measured using 1H-MRS and LC-MS/MS in gliomas, and to detect IDH mutation with machine learning based on 1H-MRS and LC-MS/

Abstract:
The MAPK signaling pathway with BRAF mutations has been shown to drive the pathogenesis of 40–60% of melanomas. Inhibitors of this pathway’s BRAF and MEK components are currently used to treat these malignancies. However, responses to these treatments are not always successful. Therefore, identifying noninvasive biomarkers to predict treatment responses is essential for personalized medicine in melanoma. Using noninvasive 1H magnetic resonance spectroscopy (1H MRS), we previously showed that BRAF inhibition reduces lactate and alanine tumor levels in the early stages of effective therapy and c

The association of acute and short-term MA abstinence on brain metabolism, in adult MA abusers, is understudied. Negative relationships with brain metabolism, cognitive development and executive functioning in prenatally MA exposed children are reported, however these studies are limited. The aim of this study was to investigate the relationship between MA and brain metabolism in adults after acute and short-term abstinence.
