Metabolic Response of the Immature Right Ventricle to Acute Pressure Overloading

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
BackgroundSurgical palliation or repair of complex congenital heart disease in early infancy can produce right ventricular (RV) pressure overload, often leading to acute hemodynamic decompensation.

Effect of Water Suppression and Metabolite Cycling on Quantification of 1H MRS Spectra in the Human Brain at 3 Tesla

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study investigates the effect of VAPOR water suppression and metabolite cycling on metabolite quantification and macromolecules in proton magnetic resonance spectroscopy. Methods Single‐voxel semi‐LASER spectra (TR/TE = 3000/28 ms) and metabolite‐nulled spectra (macromolecules) were acquired in five healthy subjects in the ...

Vitamin D supplementation does not improve human skeletal muscle contractile properties in insufficient young males [PDF]

, 2014
Vitamin D may be a regulator of skeletal muscle function, although human trials investigating this hypothesis are limited to predominantly elderly populations.

Preclinical 1H MRS Study of a Porcine Model Shows Evidence and Mechanisms for Acute Neuronal Injury in Neonatal Cardiopulmonary Bypass (CPB) Surgery

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Congenital heart disease affects 1% of US births, with some infants requiring cardiothoracic surgery under cardiopulmonary bypass (CPB). Optimal surgical parameters to minimize neuronal injury are unknown. We used serial 1H MRS in a neonatal CPB porcine model to assess acute neuronal damage and associated injury mechanisms.

Phosphocreatine in Red and White Muscle

Experimental Biology and Medicine, 1951
ConclusionThe creatine phosphate content of the white breast muscle of the fowl was found to be over twice as great as that of the red leg muscle. In the “flying” bird, the pigeon, the red breast muscle and the leg muscle contained approximately the same levels of this high energy phosphate.

The Impact and Reliability of Tissue Segmentation on In Vivo Magnetic Resonance Spectroscopy Metabolite Quantification

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Quantification of metabolite concentrations using MRS requires tissue‐dependent signal corrections. Accurate estimation of voxel tissue composition is therefore essential. Commonly used brain tissue segmentation tools differ in their algorithms and implementation, potentially introducing variability in MRS‐derived concentration ...
