Nitrite in Hypertrophic Cardiomyopathy (HCM) Study

2017-08-16 16:08:21 | BioPortfolio


Inorganic nitrate, which is found at high levels in green leafy vegetables, is reduced to nitrite by bacteria in the mouth, swallowed, and absorbed in the stomach into the blood. Studies have shown that increasing the blood levels of nitrite improves the way that muscles use oxygen and energy during exercise, and potentially blood flow.

Some people (~1 in 500) suffer from a type of genetic heart condition known as hypertrophic cardiomyopathy (HCM). This condition means that the muscle in the heart does not use energy well and becomes larger than average, meaning that they have to tap into the heart's 'energy reserves'. It is not known if nitrite has the same beneficial effects on heart muscle as on other muscles in the body. Our study will explore the mechanism by which nitrite may improve the function and energy status of the heart in HCM.

Medical and Biotech [MESH] Definitions

A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.

Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).

Magnetic resonance spectroscopy involving detection of changes in the resonance of carbon-13 nuclei in organic molecules.

Spectroscopy technique which measures changes in organic compounds by tracking the spectral energy of absorption of HYDROGEN atoms.
