Natriuretic peptide receptor C contributes to disproportionate right ventricular hypertrophy in a rodent model of obesity-induced heart failure with preserved ejection fraction with pulmonary hypertension

open access: yesPulmonary Circulation, 2019
Heart failure with preserved ejection fraction (HFpEF) currently has no therapies that improve mortality. Right ventricular dysfunction and pulmonary hypertension are common in HFpEF, and thought to be driven by obesity and metabolic syndrome.

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

open access: yesAdvanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...
