we describe a case of visceral leishmaniasis (vl) due to leishmania tropica in a 50-year-old iranian man lived in a vl-endemic area in southwest of iran. the patient presented with a 3-month history of fever and splenomegaly. clinical signs and serological findings were suggestive of vl. spleen biopsy was taken from the patient and intracellular forms of leishmania amastigotes was seen in giems...

aspergillus fumigatus is a saprophyte fungus, widely spread in a variety of ecologicalniches and the most prevalent aspergilli responsible for human and animal invasiveaspergillosis. the first step to develop novel and efficient therapies is the identificationand understanding of the key tolerance and virulence factors of pathogens. the mainfocus of the present study is to perform the similarit...

pistacia atlantica subsp. mutica is one of the most valuable forest tree species in iran that has been severely exploited for a long time. therefore, understanding the genetic diversity of different populations can be an important step towards the development and restoration of the habitat of this invaluable tree species. in this study, in order to study the genetic diversity, 10 populations in...

Spruce-fir-beech mixed forests cover a large area in European mountain regions, with high ecological and socio-economic importance. As elevation-zone systems they are highly affected by climate change, which is modifying species growth patterns productivity shifts among species. The extent to associated tree can access resources grow asynchronously may affect their resistance persistence under ...

the genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. the results revealed that the single shell weight showed higher genetic variation such as pcv% (17.20%), gcv% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. the d2 (mahalonobis? distance) statistics revealed...
