Monte Carlo Analysis of Optical Interactions in Reflectance and Transmittance Finger Photoplethysmography [PDF]

open access: yes, 2019
Photoplethysmography (PPG) is a non-invasive photometric technique that measures the volume changes in arterial blood. Recent studies have reported limitations in developing and optimising PPG-based sensing technologies due to unavailability of the ...

Irisin Attenuates Pulmonary Vascular Remodeling in Pulmonary Arterial Hypertension via Ubiquitin‐Mediated Regulation of ENO1

open access: yesAdvanced Science, EarlyView.
Irisin is a crucial plasma biomarker and promising therapeutic target that reflects disease severity, pulmonary vascular remodeling status and clinical outcome in patients with pulmonary arterial hypertension (PAH). As a novel protective factor, irisin is downregulated in PAH. By ubiquitination, irisin promotes Enolase 1 degradation and suppresses cell

Multiresolution spatiotemporal mechanical model of the heart as a prior to constrain the solution for 4D models of the heart. [PDF]

open access: yes, 2019
In several nuclear cardiac imaging applications (SPECT and PET), images are formed by reconstructing tomographic data using an iterative reconstruction algorithm with corrections for physical factors involved in the imaging detection process and with ...

Gut Metabolite Indole‐3‐Propionic Acid Regulates Macrophage Autophagy Through PPT1 Inhibiting Aging‐Related Myocardial Fibrosis

open access: yesAdvanced Science, EarlyView.
IPA is an intestinal tryptophan metabolite whose effects decline with decreased heart function. Supplementing IPA can alleviate the aging‐related myocardial fibrosis through PPT1. PPT1 is a key protein localized to lysosomes, and IPA can restore macrophage autophagy function by regulating PPT1 expresssions, thereby reducing aging‐related myocardial ...

Maternal Cardiovascular Impairment in Pregnancies Complicated by Severe Fetal Growth Restriction [PDF]

open access: yes, 2012
—Fetal growth restriction and preeclampsia are both conditions of placental etiology and associated to increased risk for the long-term development of cardiovascular disease in the mother. At presentation, preeclampsia is associated with maternal global

The GRK2/AP‐1 Signaling Axis Mediates Vascular Endothelial Dysfunction and Atherosclerosis Induced by Oscillatory Low Shear Stress

open access: yesAdvanced Science, EarlyView.
This study highlights GRK2 is a central mediator in OSS‐induced endothelial dysfunction. OSS activates GPCRs in endothelial cells, leading to GRK2 phosphorylation and the activation of AP‐1. AP‐1 induces inflammation, while also promoting NR4A1 expression and anchoring LKB1 in the nucleus, which suppresses AMPK activity. This cascade causes endothelial

Mesencephalic Astrocyte‐Derived Neurotrophic Factor Binds BAX to Preserve Mitochondrial Homeostasis and Energy Metabolism for Relieving Myocardial Hypertrophy

open access: yesAdvanced Science, EarlyView.
MANF in cardiomyocytes interacts with BAX to impede BAX mitochondrial translocation and cytochrome c release, further stabilizing mitochondrial structure and energy supply to relieve myocardial apoptosis and hypertrophy, which indicates MANF as a novel cardioprotective factor to have a promising clinical application for myocardial hypertrophy ...

Relationship between abnormal P-wave terminal force in lead V1 and left ventricular diastolic dysfunction in hypertensive patients: the LIFE study

open access: yesBlood Pressure, 2017
Background: Abnormal P-wave terminal force in lead V1 (PTF-V1) is an ECG marker of increased left atrial (LA) volume, elevated LA filling pressures and/or LA systolic dysfunction.

CD74 Blockade Disrupts Endothelial Migrasome Signaling to Prevent Inflammatory Macrophage Differentiation and Inhibit Atherosclerotic Progression

open access: yesAdvanced Science, EarlyView.
Migrasomes play a crucial role in endothelial‐immune interactions in atherosclerosis. This study identifies migrasomes as amplifiers in the inflammatory cascade, driving immune‐metabolic reprogramming via “migrasome‐APP‐CD74” signaling. Blocking CD74 disrupts migrasome‐mediated signaling, attenuating atherosclerosis progression.
