Anatomical and hemodynamic evaluations of the heart and pulmonary arterial pressure in healthy children residing at high altitude in China

International Journal of Cardiology: Heart & Vasculature, 2015
Objectives: Altitude-hypoxia induces pulmonary arterial hypertension and altered cardiac morphology and function, which is little known in healthy children at high altitude.

Changes in hemodynamics of pulmonary artery using Flowire in a canine model of acute pulmonary thromboembolism

Animal Models and Experimental Medicine, EarlyView.
This study investigated changes in pulmonary artery hemodynamics using a Flowire catheter and evaluated the accuracy of Doppler echocardiography in dogs with acute pulmonary thromboembolism (PTE). Ten healthy beagles were anesthetized, and acute pulmonary hypertension (PH) was induced by injecting 300‐μm dextran microspheres.

Contrast microsphere enhancement of the tricuspid regurgitant spectral Doppler signal - Is it still necessary with contemporary scanners?

International Journal of Cardiology: Heart & Vasculature, 2017
Background: Accurate evaluation of the tricuspid regurgitant (TR) spectral Doppler signal is important during transthoracic echocardiographic (TTE) evaluation for pulmonary hypertension (PHT). Contrast enhancement improves Doppler backscatter.

Trametinib in Adults with Neurofibromatosis Type 1‐Related Symptomatic Plexiform Neurofibromas

Annals of Neurology, EarlyView.
Objective Mitogen‐activated protein kinase kinase inhibitors have shown promising results in treatment of plexiform neurofibromas in neurofibromatosis type 1 patients, but data in adults are limited. The aim of this phase 2 study was to investigate the efficacy and safety of trametinib in adults with neurofibromatosis type 1.

Biomass Fuel Use and Cardiac Function in Nepali Women. [PDF]

, 2020
BackgroundExposure to household air pollution (HAP) from cooking with biomass fuel affects billions of people. We hypothesized that HAP from woodsmoke, compared to other household fuels, was associated with adverse cardiovascular outcomes, of which there

Co‐Opting MBNL‐Dependent Alternative Splicing Cassette Exons to Control Gene Therapy in Myotonic Dystrophy

Annals of Neurology, EarlyView.
Objective Myotonic dystrophy type 1 (DM1) is a highly variable, multisystemic genetic disorder caused by a CTG repeat expansion in the 3′ untranslated region of DMPK. Toxicity is exerted by repeat‐containing DMPK transcripts that sequester muscleblind‐like (MBNL) proteins and lead to deleterious yet predictable changes in alternative splicing.
