Right Ventricular‐Vascular Uncoupling Predicts Pulmonary Hypertension in Clinically Diagnosed Heart Failure With Preserved Ejection Fraction

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Pulmonary hypertension (PH) is highly prevalent in patients with heart failure with preserved ejection fraction (HFpEF), and it is a strong predictor of adverse outcomes.

Pulmonary Congestion at Rest and Abnormal Ventilation During Exercise in Chronic Systolic Heart Failure

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2015
Background In patients with chronic heart failure, abnormal ventilation at cardiopulmonary testing (expressed by minute ventilation‐to‐carbon dioxide production, or VE/VCO2 slope, and resting end‐tidal CO2 pressure) may derive either from abnormal ...

Predicting Pulmonary Hypertension by Electrocardiograms Using Machine Learning [PDF]

arXiv, 2023
Pulmonary hypertension (PH) is a condition of high blood pressure that affects the arteries in the lungs and the right side of the heart (Mayo Clinic, 2017). A mean pulmonary artery pressure greater than 25 mmHg is defined as Pulmonary hypertension.

Probiotic‐Based Mineralized Living Materials to Produce Antimicrobial Yogurts

Advanced Healthcare Materials, EarlyView.
The self‐assembly and mineralization of collagen in the presence of probiotics produces hybrid living materials that hosts and protects the cells. Intra‐ and interfibrillar mineralization of collagen fibers, as occurring in bone, results, respectively, in a bulk and single‐cell protective layer of cells, that survive in simulated gastric conditions and,

Motion of nanodroplets near edges and wedges [PDF]

, 2006
Nanodroplets residing near wedges or edges of solid substrates exhibit a disjoining pressure induced dynamics. Our nanoscale hydrodynamic calculations reveal that non-volatile droplets are attracted or repelled from edges or wedges depending on details of the corresponding laterally varying disjoining pressure generated, e.g., by a possible surface ...

Pressure Loss and Sound Generated In a Miniature Pig Airway Tree Model [PDF]

Journal of Applied Biotechnology & Bioengineering 3 (2017) 00086, 2017
Background: Pulmonary auscultation is a common tool for diagnosing various respiratory diseases. Previous studies have documented many details of pulmonary sounds in humans. However, information on sound generation and pressure loss inside animal airways is scarce.

Gasotransmitters in Modern Medicine: Promises and Challenges in the Use of Porous Crystalline Carriers

Advanced Healthcare Materials, EarlyView.
This perspective provides an overview of the growing interest in utilizing various gasotransmitters—small gaseous signaling molecules namely nitric oxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S)—for several therapeutic applications, with emphasis on the potential use of porous materials as carriers to provide safe and controlled local ...

A rare homozygous missense GDF2 (BMP9) mutation causing PAH in siblings: Does BMP10 status contribute?

American Journal of Medical Genetics Part A, Volume 191, Issue 1, Page 228-233, January 2023., 2023
Abstract Pulmonary arterial hypertension (PAH) is a disease characterized by pathological remodeling of the pulmonary vasculature causing elevated pulmonary artery pressures and ultimately, right ventricular failure from chronic pressure overload. Heterozygous pathogenic GDF2 (encoding bone morphogenetic protein 9 (BMP9)) variants account for some (>1%)

Fluid-structure interaction modeling of blood flow in the pulmonary arteries using the unified continuum and variational multiscale formulation [PDF]

, 2020
In this work, we present a computational fluid-structure interaction (FSI) study for a healthy patient-specific pulmonary arterial tree using the unified continuum and variational multiscale (VMS) formulation we previously developed. The unified framework is particularly well-suited for FSI, as the fluid and solid sub-problems are addressed in ...
