Background and Purpose: The frequency of opportunistic fungal infections in immunocompromised patients, especially by Candida species, has sharply increased in the last few decades. The objective of this study was to analyse the ergosterol content and gene expression profiling of clinical isolates of fluconazole resistant Candida albicans. Materials and Methods: Sixty clinical samples were ide...

Statistical studies on Palynology contents of Late Cretaceous to Paleocene age Gurpi Formation in a surface section in Zagros Basin,SW Iran indicate changes in abundance, species diversity, ratio of Spiniferites to Cyclonephelium (S/C), palynological marine index(PMI) values and organic facies. These palynological variations clearly reflect fluctuations in relative sea-level and depositionalenv...

In present study, eight isolates of the genus Curvularia, recovered from plants of the cowpea, maize and bottlebrush in Khuzestan province, were identified based on molecular phylogeny in combination with morphology. The mycelial biomass of the isolates, produced in potato-dextrose-Broth, were collected by passing through filter papers and freeze-dried. DNA was extracted using a phenol...

The intron-exon structure of Khorasan native fowl interleukin-2 (IL-2) was investigated. For this purpose, twenty chickens were selected from the Native Fowl Breeding Station of Khorasan province, and genomic DNA was extracted using a modified conventional DNA extraction protocol. An 875 bp fragment of IL-2 was successfully amplified, including a small part of the promoter, exon 1, intron 1, an...

background:   human fascioliasis is an important health problem in the province of gilan, at the caspian sea, iran. there is the overlapping of both fasciolid species, fasciola hepatica and f. gigantica . recent studies on both domestic animal and lym­naeid infection furnished evidence suggesting that f. gigantica and radix gedrosiana may be the main fasciolid and lym­naeid involved in the dise...

Background: Candida auris is a globally emerging yeast pathogen that has shown not only resistance to most anti-fungal drugs but also thermo-tolerance to temperatures higher than the mammalian’s body temperature. Although it has been only a decade since the fungus was identified, its spread of infections has been rapid and quasi-epidemics have been reported. Co-occurrences of the fungus infecti...

results phylogenetic analysis of the partial ns5b region demonstrated the relatedness of isolate fsm165 to the new subtype reported from iran in 2006. moreover, some core/e1 and ns5b sequences that had a high level of similarity with fsm165 isolate were found through searching the hcv database. these sequences were previously either misclassified or could not be accurately classified. phylogene...

in this paper,  we determine necessary and sufficient tauberian conditions under which convergence in pringsheim's sense of a double sequence of fuzzy numbers follows from its $(c,1,1)$ summability. these conditions are satisfied if the double sequence of fuzzy numbers is slowly oscillating in different senses. we also construct some interesting double sequences of fuzzy numbers.
