Simultaneous Detection of GABA and Glycine Using MEGA‐PRESS With TE Optimization at 3T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To achieve the simultaneous acquisition of gamma‐aminobutyric acid (GABA) and glycine (Gly) using a MEGA‐PRESS sequence with an optimized TE at 3T. Methods MEGA‐PRESS simulations were performed at TEs 60‐88 ms to determine the optimal TE for Gly detection with minimal myo‐Inositol (mI) overlap and maximal GABA detection sensitivity ...

No effect of creatine supplementation on oxidative stress and cardiovascular parameters in spontaneously hypertensive rats

Journal of the International Society of Sports Nutrition, 2012
Background Exacerbated oxidative stress is thought to be a mediator of arterial hypertension. It has been postulated that creatine (Cr) could act as an antioxidant agent preventing increased oxidative stress.

АТP as the marker of power exchange condition at the experimental ischemia of the myocardium due to metabolic drugs introduction [PDF]

, 2016
For the purpose of definition of an adequate marker of a power exchange condition at the experimental ischemia of the myocardium due introduction of metabolic drugs, the experimental research on 60 rats-males of Wistar line has been spent.

Phosphocreatine Preconditioning Attenuates Apoptosis in Ischemia-Reperfusion Injury of Rat Brain

Journal of Biomedicine and Biotechnology, 2011
Phosphocreatine (PCr) is an endogenous compound containing high-energy phosphate bonds. It has been confirmed that PCr is effective in preventing and treating cardiac and renal ischemia-reperfusion injury. In this study, rat cerebral ischemia-reperfusion

Repeatability of Rapid Human Cardiac Phosphorus MRSI (31P‐MRSI) Using Concentric Ring Trajectory Readouts at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose PCr/ATP ratio is determined at 7 T typically using Fourier‐transform based magnetic resonance spectroscopic imaging sequences (FT‐MRSI). These sequences require acquisition times longer than desirable for inclusion in cardiac clinical trials. Concentric ring trajectory (CRT‐MRSI) has been described as an accelerated alternative k‐space

A Novel 9‐Channel 1H, 3‐Channel 31P Radiofrequency Coil for Interleaved Multinuclear Studies of Human Calf Muscle at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a double‐tuned calf coil with excellent 1H and 31P performance to study muscle physiology by interleaved 1H/31P MRS and parallel imaging at 7 T. Methods The coil combines three 1H transceive dipoles, six 1H receive‐only loops and three 31P transceive loops, arranged in a nested, half‐cylindrical layout.

Rapid Metabolic Recovery Following Vigorous Exercise in Burrow-Dwelling Larval Sea Lampreys (\u3cem\u3ePetromyzon marinus\u3c/em\u3e) [PDF]

, 2001
Although the majority of the sea lamprey’s (Petromyzon marinus) life cycle is spent as a burrow-dwelling larva, or ammocoete, surprisingly little is known about intermediary metabolism in this stage of the lamprey’s life history.

Insulin restores metabolic function in cultured cortical neurons subjected to oxidative stress [PDF]

, 2006
We previously demonstrated that insulin has a neuroprotective role against oxidative stress, a deleterious condition associated with diabetes, ischemia, and age-related neurodegenerative diseases.

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

Magnetic Resonance in Medicine, EarlyView.
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).
