We report a case of percutaneous atrial septal defect closure (ASD) in which, despite careful device selection and successful shunt closure, a number of adverse echocardiographic features developed, necessitating surgical extraction of the device and patch closure of the defect. Lessons regarding case selection, device choice, appropriate follow-up and recognition of adverse echocardiographic f...

Time-lapse imaging of cell colonies in microfluidic chambers provides time series of bioimages, i.e., biomovies. They show the behavior of cells over time under controlled conditions. One of the main remaining bottlenecks in this area of research is the analysis of experimental data and the extraction of cell growth characteristics, such as lineage information. The extraction of the cell line b...

In this paper, we propose an polarimetric SAR interferometry technique for interferometric phase extraction of each local scatterer of the forest region. The proposed method formulated for local scattering center extraction is based on the ESPRIT algorithm which is known for high-resolution capability of closely located incidences. The method shows high-resolution performance when local scatter...

Topical application of natural antioxidants has proven to be effective in protecting the skin against ultraviolet-mediated oxidative damage and provides a straightforward way to strengthen the endogenous protection system. However, natural products can provoke skin adverse effects, such as allergic and irritant contact dermatitis. Skin irritation potential of Castanea sativa leaf ethanol:water ...

BACKGROUND Understanding the excretion of 3,4-methylenedioxymethamphetamine (MDMA) and metabolites in sweat is vital for interpretation of sweat tests in drug treatment, criminal justice, and workplace programs. METHODS Placebo, low (1.0 mg/kg), and high (1.6 mg/kg) doses of oral MDMA were given double-blind in random order to healthy volunteers (n = 15) with histories of MDMA use. Participan...

Deep learning (DL) models have recently been widely used in UAV aerial image semantic segmentation tasks and achieved excellent performance. However, DL are vulnerable to adversarial examples, which bring significant security risks safety-critical systems. Existing research mainly focuses on solving digital attacks for segmentation, but patches with physical attack attributes more threatening t...

Background: Channa striatus or better known as the haruan fish is an indigenous, snakehead, striped, air breathing freshwater fish of Malaysia and has long been consumed traditionally during post-operative and post-partum period to speed recovery. Most medical properties of the haruan are contributed to its high content of essential fatty and amino acids. This was a phase I clinical trial to ex...

Background: Inlet patch (IP) lesion is the presence of gastric columnar epithelial tissue outside of the stomach. Symptoms such as a lump in the throat, chronic cough, laryngitis, or other mouth-throat symptoms may be IP-related only and have no other abnormalities. This study aimed to determine the relationship between globus sensation and structural disorder of Inlet Patch in patients with ga...

Most of the existing semantic segmentation approaches with image-level class labels as supervision, highly rely on initial activation map (CAM) generated from standard classification network. In this paper, a novel ‘`Progressive Patch Learning’' approach is proposed to improve local details extraction classification, producing CAM better covering whole object rather than only most discriminativ...
