in this study, urease production was investigated among thirteen strains of aspergillus niger seven strains isolated from soils of semnan province in iran and six strains obtained from persian type culture collection (ptcc). the enzyme production was screened in two submerged media quantitatively. the registered ptcc 5011 and the native s31 strains showed more urease production than the other e...

BACKGROUND Mass screening for celiac disease (CD) as a public health intervention is controversial. Prior to implementation, acceptability to the targeted population should be addressed. We aimed at exploring adolescents' and parents' experiences of having the adolescents' CD detected through mass screening, and their attitudes towards possible future mass screening. METHODS All adolescents (...

Several studies suggest that the temperature of the inner canthus of the eye (T(ca)), determined with infrared thermal imaging, is an appropriate method for core temperature estimation in mass screening of fever. However, these studies used the error prone tympanic temperature as a reference. Therefore, we compared T(ca) to oesophageal temperature (T(es)) as gold standard in 10 subjects during ...

A trial of a modified reverse passive haemagglutination test for HBsAg using a 0.1% cell suspension instead of the recommended 1% showed an approximately eight-fold increase in detection sensitivity. The test can be performed within 30 minutes and lends itself to mass screening techniques. Confirmation tests can be done using the 0.1% method. In addition, the same serological plates and cells u...

Mass drug administration (MDA) has received renewed interest over the past decade in the context of malaria elimination, as part of multidrug resistance containment and (more recently) in emergency situations such as the West African Ebola outbreak. To develop WHO recommendations, a group of experts met in April 2015 to review recent evidence on the use of MDA, mass screening and treatment (MSA...
