Antiproliferative and structure activity relationships of amaryllidaceae alkaloids
(MDPI, 2015-07-30)Acceso abiertoThe antiproliferative activity of a set of seven natural Amaryllidaceae alkaloids and 32 derivatives against four cancer cell lines (A2780, SW1573, T47-D and WiDr) was determined. The best antiproliferative activities were ... -
Assessment of diastolic function and atrial remodeling by MRI – validation and correlation with echocardiography and filling pressure
(WileyAmerican Physiological Society, 2018-09-05)Acceso abiertoAtrial fibrosis can be estimated noninvasively by magnetic resonance imaging (MRI) using late gadolinium enhancement (LGE), but diastolic dysfunction is clinically assessed by transthoracic echocardiography (TTE), and ... -
Bedforms-ATM, an open source software to analyze the scale-based hierarchies and dimensionality of natural bed forms
(Elsevier, 2018-06-30)Acceso abiertoBedforms-ATM (Bed forms analysis toolkit for multiscale modeling) is a software designed to hierarchize and quantify the dimensionality of natural bed forms fields. It comprises four modular applications, namely: (1) wavelet ... -
Boundary discontinuous Fourier analysis of thick beams with clamped and simply supported edges via CUF
(Chinese Journal of Aeronautics, 2017-07-11)Acceso abiertoThis paper presents an analytical solution for static analysis of thick rectangular beams with different boundary conditions. Carrera's Unified Formulation (CUF) is used in order to consider shear deformation theories of ... -
Despeckle filtering for multiscale amplitude-modulation frequency-modulation (AM-FM) texture analysis of ultrasound images of the intima-media complex
(Hindawi Publishing Corporation, 2014-03-09)Acceso abiertoThe intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). Typically, the IMT grows with age and this is used as a sign of increased risk of ... -
