Ethnomedicinal uses, phytochemistry, pharmacological activities, and toxicology of the subfamily Gomphrenoideae (Amaranthaceae): A comprehensive review

Chemistry &Biodiversity, Accepted Article.
The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its promising ...

Multi-epoch Sub-arcsecond [Fe II] Spectroimaging of the DG Tau Outflows with NIFS. II. On the Nature of the Bipolar Outflow Asymmetry [PDF]

, 2014
The origin of bipolar outflow asymmetry in young stellar objects (YSOs) remains poorly understood. It may be due to an intrinsically asymmetric outflow launch mechanism, or it may be caused by the effects of the ambient medium surrounding the YSO. Answering this question is an important step in understanding outflow launching.

Preliminary experience with continuous right ventricular pressure and transesophageal echocardiography monitoring in orthotopic liver transplantation.

PLoS ONE, 2022
BackgroundDespite increasing attention in the cardiac anesthesiology literature, continuous measurement of right ventricular pressure using a pulmonary artery catheter has not been described in orthotopic liver transplantation, despite similarities in ...

Left Ventricular Outflow Tract Obstruction in Hypertrophic Cardiomyopathy Patients Without Severe Septal Hypertrophy: Implications of Mitral Valve and Papillary Muscle Abnormalities Assessed Using Cardiac Magnetic Resonance and Echocardiography.

Circulation Cardiovascular Imaging, 2015
BACKGROUND In patients with hypertrophic cardiomyopathy and left ventricular outflow tract (LVOT) obstruction, but without basal septal hypertrophy, we sought to identify mitral valve (MV) and papillary muscle (PM) abnormalities that predisposed to LVOT ...

Alcohol Ablation of Right Ventricular Outflow Tract Obstruction

JACC: Cardiovascular Interventions, 2014
A 28-year-old woman with valvular and infundibular pulmonary narrowing (peak Doppler gradients of 120 mm Hg) had presented to us in the last trimester of pregnancy. She had an uneventful delivery, and subsequently, she underwent elective pulmonary valve balloon dilation ([Figs.

Clinical outcomes of radiofrequency catheter ablation of ventricular tachycardia in patients with hypertrophic cardiomyopathy

Journal of Cardiovascular Electrophysiology, Volume 34, Issue 1, Page 219-224, January 2023., 2023
Abstract Background Monomorphic ventricular tachycardia (VT) is rare in patients with hypertrophic cardiomyopathy (HCM), management of which is challenging. Limited data exists on the utility of catheter ablation for the treatment of VT in this population.

Knowledge Transfer for Few-shot Segmentation of Novel White Matter Tracts [PDF]

arXiv, 2021
Convolutional neural networks (CNNs) have achieved stateof-the-art performance for white matter (WM) tract segmentation based on diffusion magnetic resonance imaging (dMRI). These CNNs require a large number of manual delineations of the WM tracts of interest for training, which are generally labor-intensive and costly. The expensive manual delineation

Dynamic simulation of aortic valve stenosis using a lumped parameter cardiovascular system model with flow regime dependent valve pressure loss characteristics [PDF]

arXiv, 2022
Valvular heart diseases are growing concern in impoverished parts of the world, such as Southern-Africa, claiming more than 31 % of total deaths related to cardiovascular diseases. The ability to model the effects of regurgitant and obstructive lesions on the valve body can assist clinicians in preparing personalised treatments.

Aortic Root Anatomy and Impact on New‐Onset Left Bundle Branch Block After Transcatheter Aortic Valve Implantation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Angulation of virtual basal ring (VBR), also known as aortic annulus, in relation to sino‐tubular junction (STJ) may lead to greater exposure of implanted stent to the conduction system, consequently increasing the risk of left bundle branch block (LBBB).

Long‐term outcomes for different surgical strategies to treat left ventricular outflow tract obstruction in hypertrophic cardiomyopathy

European Journal of Heart Failure, 2018
Surgical intervention is used to treat dynamic left ventricular outflow tract obstruction (LVOTO) in hypertrophic cardiomyopathy. This study assesses the effect of different surgical strategies on long‐term mortality and morbidity.
