myiasis is due to the opportunistic dipterous larvae feeding on viable or necrotic tissues of the host occurring throughout the world. we report a case of oral myiasis in an immune-compromised patient suffering from nonhodgkin lymphoma. we  would like  to  emphasize that such ectoparasitic infections may happen in  immuno- compromised patients and oral hygiene should be evaluated in all of thes...

Background: Following the expansion of human infertility, different procedures have been utilized for separation of normal sperm during ICSI (Intra cytoplasmic sperm injection). Hypo-osmotic swelling test (HOST) is one of the tests which have been introduced for assessment of integrity of sperm membrane when confronted with hypo osmotic condition. This test may also reflect intracellular organe...

Background: During ICSI, motile sperm with normal morphology are selected and injected into oocyte. But integrity of chromatin is not observable. Therefore, researchers are trying for to present novel method of sperm selection with high percentage of normal chromatin. HOST test is a useful assay of functional integrity of the human sperm membrane. We decide to use HOST test after DGC for infert...

this report is part of a national project for gathering and classifying the arthropod seed feeders in different provinces of iran between 2008–2014. in this paper, nineteen host species with their areas of distribution are presented for twelve species of seed beetles (chrysomelidae: bruchinae). most of the identified host plants (84%) belong to the family fabaceae (leguminosae). in addition, al...

T he paper uses Heckman model to examine the statistical importance of over 140 independent variables on the Olympic performance of all countries participating in the Summer Olympic Games from Sydney 2000 to Rio 2016. We find that countries which export more products have a higher likelihood of winning an Olympic medal than their counterparts exporting fewer products, and explain why...
