The circadian clock is responsible for the temporal regulation of various physiological processes in plants. Individual cells contain a circadian oscillator consisting of a clock gene circuit that coordinates physiological rhythms within the plant body in an orderly manner. The coordination of time information has been studied from the perspective of cell-cell local coupling and long-distance communication between tissues based on the view that the behavior of circadian oscillators represents physiological rhythms.

- - The study focused on the plant circadian oscillation system, utilizing a dual-color bioluminescence monitoring system to observe the circadian behavior of individual cells via two luciferase reporters: AtCCA1::LUC+ and CaMV35S::PtRLUC.
- - The researchers introduced these reporters into duckweed cells and monitored the bioluminescence to compare rhythms, finding that AtCCA1::LUC+ exhibited a strong circadian rhythm while CaMV35S::PtRLUC displayed more variable, stochastic rhythms.
- - The results indicated a decoupling of circadian behaviors between the two reporters, highlighting the capability of the dual-color system to study cell-to-cell variations in gene expression
Background: Direct evidence of inflammatory activity in the atria of patients with atrial fibrillation (AF) is scarce. We assessed the capability of positron-emission tomography/computed tomography (PET/CT) to diagnose AF based on fluorodeoxyglucose (FDG) uptake in the atrial wall.
Methods And Results: Among 8233 patients who underwent FDG-PET/CT as work-up for malignancies, we identified 180 consecutive patients with AF (2.
Background: Quantitative assessment of myocardial flow reserve (MFR) by single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) is challenging but may facilitate evaluation of multi-vessel coronary artery disease (CAD).
Methods: We enrolled 153 patients with suspected or known CAD, referred for pharmacological stress MPI. They underwent a Tc-perfusion stress/rest SPECT with an ultrafast cadmium-zinc-telluride (CZT) camera.
