outbreaks causing mass mortalities have been observed in the golden grey mullet (liza auratus) population in southern coastal area of the caspian sea since 2002. the clinical signs include neurological abnormalities, such as erratic swimming behavior, spiral swimming, belly-up at rest and over inflation of the swim bladder. three hundred and twelve samples of moribund fish with sizes that range...

The use of trade, firm, or corporation names in this protocol is for the information and.jor consideration in designing a nested PCR protocol compatible with quantitation is to assure that the maximum concentration of PCR products produced by the....

background and purpose: pneumocystis pneumonia, caused by pneumocystis jirovecii, is a fatal disease threatening patients with aids or immunosuppression. assessment of colonization in these patients is of great significance, since it can lead to severe pulmonary disorders. considering the scarcity of published reports on pneumocystis jirovecii isolates from patients in mashhad, iran, we aimed t...

background: hepatitis c is a disease with significant global impact. the distribution of hepatitis c virus (hcv) genotypes in mashhad (the northeast and the biggest city after the capital of iran) is unknown. the purpose of this study was to determine the prevalence of hcv genotypes among hcv seropositive patients, and to study the relationship between types, virologic and demographic features ...

Here, an efficient cloning strategy for large DNA fragments and for simultaneous assembly of multiple DNA fragments assembly is presented. This strategy is named OEPR (based on Overlap Extension PCR and Recombination in vivo). OEPR cloning is a seamless, restriction- and ligation-independent method. The method takes advantage of both homologous recombination enzymes in E. coli and overlap PCR. ...

By use of a 3' extension PCR strategy, cDNA clones were isolated spanning the transmembrane region and a complete cytoplasmic domain of the human interleukin 5 receptor alpha subunit (hIL5R alpha). These cDNAs differ from previously isolated clones encoding a soluble hIL5R alpha form by a sequence switch at position 1243. When expressed in COS-1 cells, only low-affinity binding of 125I-labeled ...

This study demonstrated determination of fetal gender from nucleated red blood cells (NRBCs) in maternal blood and attempted to apply prenatal diagnosis of hemophilia A using BclI DNA polymorphism. Venous blood was drawn from 20 pregnant women, and NRBCs were recovered by magnetic activated cell sorting and anti-GPA (glycophorin A) immunostaining. After microdissector isolation of the NRBCs, pr...
