Metabolic Memory in Cardiovascular Disease: Encoding, Propagation, and Therapeutic Targeting

open access: yesAdvanced Science, EarlyView.
Cardiovascular risk often persists after metabolic abnormalities are corrected. This conceptual Review frames such persistence as metabolic memory, encoded through a narrowing therapeutic window from reversible marks to irreversible damage, with continuous input from peripheral organs.

CDK4/MERCs/PINK1 Axis Drives PFOA/HFPO‐TA‐Induced Cardiac Senescence via Mitophagy Defect and cGAS‐STING Activation: In Vitro Amelioration by Cycloastragenol

open access: yesAdvanced Science, EarlyView.
The present study demonstrated that PFOA and HFPO‐TA exposure suppressed CDK4, disrupted MERCs and impaired PINK1/Parkin‐mediated mitophagy, thereby accelerating cardiac senescence, whereas CAG effectively reversed these pathological changes in vitro. Our findings identify CDK4 as a critical regulator bridging mitophagy defects and cardiac senescence ...

Coronary input impedance is constant during systole and diastole

open access: yes, 1991
Although it is well known that coronary inflow decreases substantially during systole, the mechanism responsible for this decrease remains controversial. Knowledge of how coronary input impedance is affected by contraction can differentiate between some

SerpinA3 is an Endogenous TGF‐β Receptor Antagonist that Attenuates Cardiac Fibroblast Activation and Fibrotic Remodeling

open access: yesAdvanced Science, EarlyView.
SerpinA3 acts as an endogenous TGF‐β receptor antagonist that binds to the extracellular domain of TGFR‐1, thereby preventing TGFR‐1–TGFR‐2 complex formation. This receptor‐level blockade suppresses TGF‐β/Smad2/3 signaling, attenuates cardiac fibroblast activation, and extracellular matrix deposition, and ultimately alleviates pressure overload–induced

Hyperaemic blood‐flow velocities in systole and diastole relate to coronary risk in divergent ways

open access: yes, 2008
BACKGROUND: A recent study suggested blood-flow velocity in diastole during reactive hyperaemia as a major driver of flow-mediated vasodilation (FMD) of the brachial artery, also being related to cardiovascular risk factors.

Increased Disarray of Extracellular Matrix Collagen‐I Fiber Network and Compromised Biomechanics in Aortae From Marfan‐Syndrome Mice Assessed Through Combined Opto‐Biomechatronics

open access: yesAdvanced Science, EarlyView.
Combined structure‐function assessment in aortic rings from Marfan mice using MechaMorph Opto‐Biomechatronics technology relates increased elasticity (stiffness) and dynamic viscosity and less ordered extracellular matrix 3D‐structure (collagen) as potential causes for impaired Windkessel function and compromised haemodynamics in Marfan's syndrome ...

Gut Microbiota‐Derived Indole‐3‐Propionic Acid Alleviates Diabetic Osteoporosis Through Nrf2‐Mediated Ferroptosis Suppression

open access: yesAdvanced Science, EarlyView.
Diabetes‐associated dysbiosis is accompanied by reduced Clostridium abundance, impaired microbial tryptophan metabolism, and lower circulating indole‐3‐propionic acid (IPA). Exogenous IPA improves trabecular microarchitecture and bone formation and restores Nrf2‐associated antioxidant signaling in bone marrow mesenchymal stem cells, limiting iron ...

The times they are a-changin': Two-dimensional aortic valve measurements differ throughout diastole

open access: yes, 2016
Introduction Diastolic aortic valve measurements are used to obtain weight-independent cardiac ratiometric indices. However, whether clinically important variations in valve measurements occur during diastole remains undetermined.

Beneficial Body Mass Index for Age‐Related Kidney Function in Males and Females

open access: yesAGING MEDICINE, EarlyView.
The impact of BMI on age‐related kidney function decline is highly sex‐ and age‐dependent. Normal BMI (18.5–25 kg/m2) is associated with better age‐related kidney function in all‐aged males and females older than 45 years. ABSTRACT Objectives Kidney function declines with aging, leading to a high prevalence of age‐related disease.
