Faster and More Robust CK Reaction Rate Estimation at 3T Using Acquisition‐Weighted 31P Cardiac 1D‐MRSI With Compartment‐Based Reconstruction

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Quantification of the creatine kinase (CK) forward reaction rate (kf) in the human heart using phosphorus magnetic resonance spectroscopy is clinically important; however, it is limited by long acquisition times, operator subjectivity in analysis, and potential skeletal muscle contamination.

Transverse Relaxation Time Constant of Cystathionine in Human Glioma at 3 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Cystathionine (Cth) has emerged as a promising biomarker for identifying 1p/19q codeleted gliomas. However, little is known about the T2 relaxation time constant of Cth in gliomas. The aim of this study was to measure the T2 of Cth in vivo in glioma and compare it to the T2s of other metabolites at 3 T.

Short Echo‐Time Spiral MRSI Versus Single‐Voxel Spectroscopy in the Human Brain at 3 Tesla With Semi‐LASER Localization

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Magnetic resonance spectroscopy techniques are widely used to non‐invasively study brain metabolism. Despite advances in magnetic resonance spectroscopic imaging (MRSI), there is a notable absence of research on comparing fast non‐Cartesian MRSI with single‐voxel spectroscopy (SVS), limiting our understanding of its performance and ...

High‐Temporal‐Resolution Monitoring of Creatine and Phosphocreatine Dynamics in Skeletal Muscle Using Ultrafast Z‐Spectroscopy (UFZ) CEST MRI at 3T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate the feasibility of High‐Temporal‐Resolution (HTR) Ultrafast Z‐spectrum (UFZ) CEST MRI for monitoring the dynamic fluctuations of phosphocreatine (PCr) and creatine (Cr) in human skeletal muscle (SM) at 3 T during and after exercise.

Analysis of creatine kinase activity with evaluation of protein expression under the effect of heat and hydrogen peroxide [PDF]

The Ukrainian Biochemical Journal, 2015
Protein oxidation has detrimental effects on the brain functioning, which involves inhibition of the crucial enzyme, brain type creatine kinase (CKBB), responsible for the CK/phosphocreatine shuttle system. Here we demonstrate a susceptibility of CKBB to

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

Pest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

THE HYDROLYSIS OF PHOSPHOCREATINE AND THE ORIGIN OF URINARY CREATININE

Journal of Biological Chemistry, 1947
Shaffer (1), Myers and Fine (2), and Hahn and Meyer (3) adduced evidence that muscle creatine is the precursor of urinary creatinine. This was questioned by Chanutin and Kinard (4) but was conclusively proved by Bloch, Schoenheimer, and Rittenberg (5, 6) by isotope tracer evidence, which also showed that creatinine was the only normal urinary ...
