background and aims: glucose-6-phosphate dehydrogenase (g6pd) is the first enzyme in the route of pentose phosphate metabolism. this route fulfills an effective role in removing oxidant metabolites. deficiency of this enzyme causes decline in energy regeneration of red blood cells and hemolysis. in this study, application of fluorescence staining method in diagnosing the frequency of g6pd defic...

background: glucose-6-phosphate dehydrogenase (g6pd) deficiency is the most common disease of the hexose monophosphate pathway existing in more than 400 million people worldwide. the aim of this study was to identify neonates with g6pd deficiency following national program for screening and education of affected newborns’ parents started since june 2007 in mazandaran, a northern province of ira...

BACKGROUND Most universities currently practice traditional practical spot tests to evaluate students. However, traditional methods have several disadvantages. Computer-based examination techniques are becoming more popular among medical educators worldwide. Therefore incorporating the computer interface in practical spot testing is a novel concept that may minimize the shortcomings of traditio...

Background The sensitivity of smear microscopy for diagnosis of tuberculosis might be improved through treatment of sputum with sodium hypochlorite and application of fluorescent microscopy. This study aimed to determine the agreement between direct Fluorescent Microscopy and Ziehl-Neelsen concentration technique by their ability of detecting acid fast bacilli in resource poor settings. Metho...

Spots are image details resulting from objects, the projections of which are so small that the inner structure of these objects cannot be resolved from their image. Spot detectors are image operators aiming at the detection and localisation of spots in the image. Most spot detectors can be tuned with parameters. This paper addresses the problem of how to select the parameters. We propose to use...
