Longitudinal Displacement for Left Ventricular Function Assessment
Journal of Cardiovascular Development and DiseaseBackground: Quantitative evaluation of myocardial function traditionally relies on parameters such as ejection fraction and strain. Strain, reflecting the relative change in the length of a myocardial segment over the cardiac cycle, has been extensively ...

Sleep Alters the Velocity of Physiological Brain Pulsations in Humans
Advanced Science, EarlyView.Sleep alters I/CSF oscillatory flow, driven by increased respiratory (29%) and vasomotor pulsation (21%) velocities, while cardiovascular pulsations decreased by (22%). Velocity is quantified using optical flow analysis of MREG data. Spectral power increases alongside these pulsations (spatial correlation, r = 0.35 and r = 0.39, respectively ...

Left ventricular diastolic function and cardiotoxic chemotherapy
The Egyptian Heart JournalBackground Left ventricular ejection fraction falls when the myocardium has already lost a significant portion of its functional capacity. There are conflicting data on whether diastolic dysfunction precedes systolic dysfunction after cardiotoxic ...

Astrocyte Enrichment of 3D Cortical Constructs Enhances Brain Repair
Advanced Science, EarlyView.This study highlights the role of astrocytes in supporting neural progenitor cell survival and differentiation after traumatic brain injury. Astrocytes enhanced neuronal differentiation, improved cell survival in co‐cultures, and promoted integration of microfluidics‐based implants with host tissue following implantation. Additionally, increased axonal

Advanced Science, EarlyView.This study revealed how the osteoblastic microenvironment determines the fate of cancer cells disseminated in bone, with a focus on whether they colonize, reside in quiescence, or reactivate from dormancy. Targeting integrin signaling may offer promising strategies for preventing quiescent cancer cells reactivation and bone colonization.
