background: xmn-1 polymorphism of

results fifty isolates were positive on the screening test. among them, positive pcr reactions were identified in 35/221 and 12/77 isolates of e. coli and klebsiella spp., respectively, including 16 (34.0%) for cit only, 7 (14.8%) for dha only, and 24 (51.0%) for both dha and cit. no isolate was positive for fox or mox. no proteus organism was positive for ampc genes. conclusions currently, phe...

background: we aimed to determine the incidence of co-inheritance as well as interaction of sickle cell trait (sct) and α thal /β thal mutations in south and south central of iran. method: we employed a pcr and restriction fragment length polymorphism techniques to confirm diagnosis of sickle cell trait. all subjects were screened for any α/β -thalassemia mutations using a gap-polymerase chain ...

background: the genus psammogeton edyew. which belong to the umbelliferae family, is found in central areas of asia. this genus consists of six species widespread in the sandy dunes of deserts. among the four species present in iran, pssamogeton canescens (dc.) vatke is distributed in regions of iran central. objective: the aim of this study is to determine the chemical composition of essential...

background : gestational trophoblastic neoplasia (gtn) disease is excessive and inappropriate proliferation of trophoblast after termination of the pregnancy. many attempts have been made to improve follow-up procedures, but no studies have evaluated human chorionic gonadotrophin (hcg) as a post treatment indicator. thus we aimed to know β-hcg variability in post treatment pregnancies.   method...

in this paper by using the notiαon of anti fuzzy points and its besideness to andnon-quasi-coincidence with a fuzzy set the concepts of an anti fuzzy subalgebrasin bm-algebras are generalized and their inter-relations and related propertiesare investigated.

the open pulled straw has been used effectively to vitrify preimplantation embryos because of geometricfeatures that allow rapid rates of temperature exchange. one possible inexpensive alternative to the openpulled straw are commercially-available microcapillary pipette tips commonly used for electrophoresis. themain purpose of this study was to compare the survival rates of in vitro produced b...

the taguchi design of experiments was used to test the relative importance of medium components and environmental factors on poly(β-hydroxybutyrate)(phb) production by ralstonia eutropha. the optimum condition was obtained as: fructose concentration, 15 g/l; c/n ratio, 7.4; agitation speed 200 rpm; culture time, 40 h; temperature, 25 ° c; seed age, 15 h. at optimum condition the yield of phb pr...
