Large-library fluorescent molecular arrays remain limited in sensitivity (1 × 10(6) molecules) and dynamic range due to background auto-fluorescence and scattering noise within a large (20-100 μm) fluorescent spot. We report an easily fabricated silica nano-cone array platform, with a detection limit of 100 molecules and a dynamic range that spans 6 decades, due to point (10 nm to 1 μm) illumin...

Background and Aims: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a global problem and the most common cause of jaundice in neonates. Hence, this study was conducted to investigate the prevalence of G6PD deficiency in Jiroft city in southern Kerman. Materials and Methods: This descriptive cross-sectional study was carried out from 2016 to 2019. Blood samples were taken from all patie...

SUMMARY The results of direct stool examination in 102 watery and bloody diarrhea patients were compared with the presence of antibodies against Entamoeba histolytica with Indirect Fluorescent Antibody Test. Besides 22 healthy individuals included in this study as control group. It was found that 22 patients (21.5%) with a sera titre higher than 1/320 bad only 9 (8.8%) positive E. Histolytica ...

High-density microarrays are a rapidly developing technology in molecular biology allowing one to measure simultaneously the activity of thousands of biomolecules in the cell under different experimental conditions. Two-color comparative microarray experiment is a key point of transcriptome (Yang et al., 2002; Herzel et al., 2001; Hegde et al., 2000), CGH (comparative genome hybridization, Pink...

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...

Fluorescence in situ hybridization (FISH) is a molecular diagnostic technique in which a fluorescent labeled probe hybridizes to a target nucleotide sequence of deoxyribose nucleic acid. Upon excitation, each chromosome containing the target sequence produces a fluorescent signal (spot). Because fluorescent spot counting is tedious and often subjective, automated digital algorithms to count spo...
