The development of a computer-based teaching simulation tool to aid medical imaging educators in teaching pattern recognition

Int. j. morphol; 38 (5), 2020
SUMMARY: The aim of this exploratory design science research (DSR) study was to design a computer-based teaching simulation tool (CBTST) for training medical imaging (MI) students in chest pattern recognition. A DSR methodology used in the design of the CBTST entailed the following phases: 1) awareness o...

Endovascular technique simulator for Neuroradiology learning

Arq. neuropsiquiatr; 78 (9), 2020
ABSTRACT Background: Vascular cerebral infarction (or stroke) is recognized as the third leading cause of death worldwide, and acute arterial occlusion comprises the main mechanism underlying ischemic stroke. Cerebrovascular diseases are treated by intracranial endovascular interventions employing mini...

Network prediction of the potential molecular mechanisms in birds of prey exposed to organochlorine pesticides

Acta toxicol. argent; 28 (1), 2020
Abstract In the 1960s, organochlorine compounds were responsible for the decline of birds of prey populations such as Haliaee- tus leucocephalus and Falco peregrinus. Pesticides similar to DDT cause bioaccumulation in birds, affecting their eggshell com- position and compromising their development. Using...

Upper eyelid contour symmetry measurement with Bézier curves

Arq. bras. oftalmol; 83 (1), 2020
ABSTRACT Purpose: The purpose of the present work is to measure the interocular upper lid contour symmetry using a new method of lid contour quantification. Methods: The Bézier curve tool of the Image J software was used to extract the right and left upper eyelid contours of 75 normal subjects. Inter-...

Structural-functional analyses of textile dye degrading azoreductase, laccase and peroxidase: a comparative in silico study

Background: Textile industry not only plays a vital role in our daily life but also a prominent factor in improving global economy. One of the environmental concern is it releases huge quantities of toxic dyes in the water leading to severe environmental pollution. Bacterial laccase and azoreductase succ...
