Human Activity Recognition (HAR) from time-sequential video images is an active research area in various applications such as video surveillance and smart homes nowadays. This paper presents a novel approach of automatic HAR based on Generalized Discriminant Analysis (GDA) on Enhanced Independent Component (EIC) features from binary silhouette information to be used with Hidden Markov Model (HM...

BACKGROUND The conventional right ventricular (RV) lead position in cardiac resynchronization therapy pacemakers (CRT-P) is the RV apex (RV-A). Little is known about electrophysiological stability and associated complications of pacing leads in RV high posterior septal (RV-HS) position in CRT-P. METHODS Two hundred and thirty-five consecutive CRT-P patients were included from 1999-2010. Pacin...

BACKGROUND The purpose of this study was to determine the relative contribution of fibrosis-mediated and myofibril-mediated stiffness in rats with mild and severe right ventricular (RV) dysfunction. METHODS AND RESULTS By performing pulmonary artery banding of different diameters for 7 weeks, mild RV dysfunction (Ø=0.6 mm) and severe RV dysfunction (Ø=0.5 mm) were induced in rats. The relativ...

ObjectiveThis study aimed to assess Brain Natriuretic Peptide in early diagnose of cardiac function in children with Congenital Heart Diseases.MethodologyThis study was performed on children with CHD and healthy. Severity of heart failure modified Ross classification system was used for grouping patients in four classes. For all participants, height, weight and head circumference were measured....

In humans, spironolactone and mespirenone are well known antimineralocorticoids without C-11b substituents. These compounds display antagonist properties by acting through the human androgen receptor (hAR). In contrast, we demonstrate here that synthetic mineralocorticoid antagonists bearing hydrophobic C-11b substituents and C-17g-lactone are potent hAR agonists in vitro. The three-dimensional...

Doppler-derived myocardial performance index (MPI) , defined as the s um of isovolumetric contraction and relaxation durations divided by ejection time, is an easily measured and reproducible index that shows both systolic and diastolic myocardial function. The goal of this study was to define normal values of right ventricular MPI in neonates in the first 48 to 72 hours of life. Fifty-one...

English) A global mapping of early stage medical technology companies active in the neurology field has been implemented. The companies have emerging products and have undergone an evaluation by clinicians concerning the ability to provide clinical value for Swedish health care. The evaluation process has been executed by discussion with neurologists and neurosurgeons in combination with a lite...
