The effect of exercise training on endothelial function in postmenopausal women with breast cancer under aromatase inhibitor therapy

Cancer Medicine, Volume 11, Issue 24, Page 4946-4953, December 2022., 2022
Exercise training led to significantly greater improvement in exercise capacity in postmenopausal women with aromatase inhibitor‐treated breast cancer than exercise counseling only, none the less it did not exert any measurable effects on endothelial dysfunction Abstract Background Breast cancer is the leading non‐cardiovascular cause of death in women.

Left ventricular active stiffness: dependency on time and inotropic state [PDF]

, 1978
Left ventricular systolic stiffness was measured by rapidly changing ventricular volume (within 7 ms) of isovolumically contracting isolated rabbit hearts. Instantaneous pressure-volume relations were found to be linear with slopes that depended upon the

The Placenta Regulates Intrauterine Fetal Growth via Exosomal PPARγ

Advanced Science, EarlyView.
The placenta expresses much higher levels of PPARγ than fetal adipose tissue. Trophoblastic exosomes transport PPARγ into fetal preadipocytes via fetoplacental circulation and thus regulate adipogenic genes distinct from endogenous PPARγ. Compromised placental PPARγ leads to fetal adipogenesis deficiency and intrauterine growth restriction, reversible ...

A Wavelet Approach for the Estimation of Left Ventricular Early Filling Wave Propagation Velocity from Color-M-Mode Echocardiograms [PDF]

arXiv, 2019
Objective: This work evaluates a new approach for calculating the left-ventricular (LV) early filling propagation velocity (VP) from color M-Mode (CMM) echocardiograms using wavelet analysis. Unlike current approaches, the method requires no assumptions, user inputs, or heuristic conventions.

Biodegradable and Implantable Triboelectric Nanogenerator Improved by β‐Lactoglobulin Fibrils‐Assisted Flexible PVA Porous Film

Advanced Science, EarlyView.
BF‐PVA porous film is prepared by doping BF into PVA to form hydrogel and then freeze‐drying and compression to improve the tensile resistance, bending resistance, swelling resistance, degradation time and electrical properties of PVA. Finally, the degradable triboelectric sensor made of BF‐PVA porous film and Mg film is used to realize the signal ...

Injectable pH Responsive Conductive Hydrogel for Intelligent Delivery of Metformin and Exosomes to Enhance Cardiac Repair after Myocardial Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
Injectable pH responsive conductive hydrogel for intelligent delivery of metformin and exosomes to alleviate myocardial ischemia‐reperfusion injury. The hydrogel responds to the weakly acidic microenvironment of ischemic injury and can significantly reduce the production of intracellular ROS and enhance cardiac conduction, thereby resisting apoptosis ...
