Design of Oscillatory Networks through Post-Translational Control of Network Components.

Many essential functions in biological systems, including cell cycle progression and circadian rhythm regulation, are governed by the periodic behaviors of specific molecules. These periodic behaviors arise from the precise arrangement of components in biomolecular networks that generate oscillatory output signals. The dynamic properties of individual components of these networks, such as maturation delays and degradation rates, often play a key role in determining the network's oscillatory behavior.

Cross polarization from dipolar-order under magic angle spinning: The ADRF-CPMAS NMR experiment.

Techniques for enhancing the signals arising from low-γ, insensitive (I) nuclei are central to solid-state nuclear magnetic resonance. One of the leading and best-established methods to sensitize these unreceptive species is Hartmann-Hahn cross polarization (HH-CP), a polarization transfer mechanism often executed under MAS. Herein, we explore the possibility of utilizing the 1H dipolar order created via adiabatic demagnetization in the rotating frame (ADRF), to enhance the unreceptive spins under MAS.

Severe Heart Failure Resulting From Healed Myocardial Infarction Preferentially Involving the Ventricular Septum and Leading to Orthotopic Heart Transplantation.

Described herein are 4 patients who underwent orthotopic heart transplant (OHT) because of heart failure caused by acute myocardial infarcts which healed. These healed infarcts were the result of preferential severe narrowing of the left anterior descending coronary artery. In all 4 cases, the myocardial infarct caused severe scarring of the ventricular septum (VS), more than that observed in the left ventricular free wall where most myocardial infarcts secondary to coronary artery narrowing typically occur.

Identifying and Overcoming Artifacts in H-Based Saturation Transfer NOE NMR Experiments.

Magnetization transfer experiments are versatile nuclear magnetic resonance (NMR) tools providing site-specific information. We have recently discussed how saturation magnetization transfer (SMT) experiments could leverage repeated repolarizations arising from exchanges between labile and water protons to enhance connectivities revealed via the nuclear Overhauser effect (NOE). Repeated experience with SMT has shown that a number of artifacts may arise in these experiments, which may confound the information being sought - particularly when seeking small NOEs among closely spaced resonances.
