Using Magnetic Resonance to Probe Lipid Synthesis in Response to Ketogenic Diet

Non-alcoholic Fatty Liver Disease and its progression to more serious diseases will become the main cause for liver transplant in the next 5 years. Here, researchers used deuterium magnetic resonance to study dietary influences on lipid synthesis demonstrating that high fat ketogenic diets significantly slow de novo lipogenesis, a process by which excess carbohydrates are covered into fatty acids and stored as triacylglycerols.

Prefractionation of Intact Proteins for Mass Spectrometry

Analysis of intact proteins using mass spectrometry is a difficult task that can be simplified by prefractionation, a process in which protein mixtures are separated into simpler fractions based on size. Here, researchers developed a new method, PEPPI-MS, which uses low-cost materials and common lab equipment to make an important protein separation strategy widely available.

Probing Metal Organic Frameworks with 17O NMR at 35.2 T

Metal-organic frameworks (MOFs) are porous materials with high surface areas that can host a variety of different guest molecules, leading to applications in catalysis, drug delivery, chemical separation, fuel cells, and data storage. In order to design better MOFs, knowledge of their molecular-level structures is crucial. At the MagLab, the highest-field NMR spectrometer in the world was used to probe the complex structures of MOFs both "as built" and as they exist when other "guest" molecules are inserted inside the framework.

Deuterium Magnetic Resonance Can Detect Cancer Metabolism

Magnetic resonance of cancer cell metabolism is a novel technique to discern between cancerous and normal liver cells, providing a promising approach for cancer stage progression imaging without the harmful exposure of radiation.

MRI detects brain responses to Alzheimer's disease plaque deposits and inflammation

Magnetic Resonance Imaging (MRI) of mouse models for Alzheimer’s disease can be used to determine brain response to plaque deposits and inflammation that ultimately disrupt emotion, learning, and memory. Quantification of the early changes with high resolution MRI could help monitor and predict disease progression, as well as potentially suggest new treatment methods.

Analytical tool for in vivo triple quantum MR signals

Magnetic resonance (MR) signals of sodium and potassium nuclei during ion binding are attracting increased attention as a potential biomarker of in vivo cell energy metabolism. This new analytical tool helps describe and visualize the results of MR experiments in the presence of in vivo ion binding.

Brain Waste Pathway Found

Little is known about the path of metabolic waste clearance from the brain. Here, high-field magnetic resonance images a possible pathway for metabolic waste removal from the brain and suggests that waste clearance may be one reason why we sleep.

Liquid State Dynamic Nuclear Polarization at High Magnetic Field

This finding demonstrates a path forward to dramatically enhance sensitivity for molecule concentration measurement by magnetic resonance using Overhauser DNP.

Identification of abnormal hemoglobin from human blood

Precise determination of hemoglobin sequence and subunit quantitation from human blood for diagnosis of hemoglobin-based diseases.

NMR-based Metabolomics of Coral with Resistance to Bleaching

Three variants of the coral species A cervicornis were found to have unique metabolic signatures that can be distinguished by NMR spectroscopy. Differing levels of the metabolite trimethylamine-N-oxide, an important compound that protects against nitrogen overload, can distinguish the three variants studied. Understanding how species vary metabolically, and how that translates to species survival in stressed environments, may help us to establish desirable traits that could help with restoration and other interventions.
