background: in the previous study, we have shown that the presence of a allele at position -588 in aγ-globin gene was highly frequent and closely associated with fetal hemoglobin elevation among β-thalassemia intermedia patients. therefore, we decided to investigate whether this allele (a allele at -588) could result in an increase in aγ-globin gene expression to ameliorate the severity of the ...

Transient expression is a rapid, useful approach for producing proteins of interest in plants. Tobacco mosaic virus (TMV)-based transient expression vectors can express very high levels of foreign proteins in plants. However, TMV vectors are, in general, not efficiently delivered to plant cells by agroinfection. It was determined that agroinfection was very efficient with a 35S promoterdriven T...

objective(s): we aimed to investigate the influence of transient receptor potential channel 3 (trpc3) on lipopolysaccharide-induced (lps) preterm delivery mice. materials and methods: mice were randomly assigned to the four groups: an unpregnant group, a mid-pregnancy group (e15), a term delivery group, and an lps-induced preterm delivery group (intraperitoneal injection lps at 15 days). uterin...

a stable agrobacterium-mediated transformation system was established using bialaphos as the selective agent in soybeans [glycine max (l.) merr.]. the cotyledonary node explants of the soybean cultivar ‘ny-1001’ were inoculated with the agrobacterium tumefaciens strain eha105, harboring the vector pcambia3301 containing the gus gene as the reporter gene and the bar gene conferring bialaphos res...

Haploid microspore-derived embryos (MDEs) of wheat were obtained by in vitro androgenesis. These  embryos were employed to evaluate the transient expression of GUS gene (uidA) following particle bombardment. Using the Bio-Rad PDS-1000/He system, the physical parameters including rupture disk pressure (900, 1100 and 1350 psi); microprojectile travel distance (6 and 9 cm); gold particles size (0....

background: cd19 is a pan b cell marker that is recognized as an attractive target for antibody-based therapy of b-cell disorders including autoimmune disease and hematological malignancies. the object of this study was to stably express the human cd19 antigen in the murine nih-3t3 cell line aimed to be used as an immunogen in our future study. methods: total rna was extracted from raji cells i...

detection and modification of the risk factors of stroke may be the most effective strategy for preventing its often irreversible consequences. a longitudinal prospective study was implemented to evaluate the effect of several risk factors on the course of cerebrovascular disease. the study groups were composed of 3s8 normal volunteers, and 308 patients with transient ischemic attacks. the two ...

objective(s): the alteration of glucose transporters is closely related with the pathogenesis of brain edema. we compared neuronal damage/death in the hippocampus between adult and young gerbils following transient cerebral ischemia/reperfusion and changes of glucose transporter-1(glut-1)-immunoreactive microvessels in their ischemic hippocampal ca1 region. materials and methods: transient cere...

abstract benzylisoquinoline alkaloids are a diverse group of nitrogenous compounds which is found in about 20% of plant species. isolation of effective genes involved in morphine biosynthesis of opium poppy is very important in the production of specific which can be achieved using metabolic engineering techniques. in this biosynthesis pathway, the key enzyme sat is involved in the conversion o...

BACKGROUND Grasses are relatively recalcitrant to genetic transformation in comparison to certain dicotyledons, yet they constitute some of the most important biofuel crops. Genetic transformation of switchgrass (Panicum virgatum L.) has previously been reported after cocultivation of explants with Agrobacterium and biolistics of embryogenic calli. Experiments to increase transient gene express...
