objective(s): htlvi-1 is the first human retrovirus with limited endemic regions in the world. the epidemiological studies have shown that the genetic background and immune response to the virus have a significant role in htlv-i-associated diseases.  among the genes are involved in htlv-i infection, the role of human leukocytes antigen (hla) have been studied in different population. in the pre...

to mutate the ice nucleation active (ina) gene in erwinia herbicola strains, tn-5 transposon carried by psup2021 plasmid was used. this plasmid was transferred to the bacterial cells by electroporation. electrotransformation was carried out for 2.5 ms at 1800 v and 1 mm distance between the electrodes. polymerase chain reaction was used for determination of presence or loss of ina gene, using a...

the essential oils isolated by hydrodistillation from the leaves of two eucalyptus gillii maiden and e. microcarpa subsp. macrocarpa hook were analysed by gc and gc/ms. the main components identified in e. gillii oil were 1, 8-cineole (79.5%), trans-pinocarveol (8%) and ?-pinene (2.7%), and in e. microcarpa were 1, 8-cineole (77.3%), ?-pinene (5.6%) and terpin-1-ol (5.1%). oils with high conten...

in order to investigate the effects of municipal waste compost and benefit fungi of trichoderma species on seedling emergence parameters, growth and some micronutrients uptake of garden cress a pot experiment was carried out in factorial arrangement based on randomized complete block design with 3 replications. treatments consisted of three levels of municipal waste compost (15, 30, 45 mg ha-1 ...

polyamide-66(pa66)/caco3 micro- and nano-composites were prepared using a polymer solution method at filler loading of 0, 1, 2 and 3 weight percent. nano-size of caco3 was synthesized by micro-emulsion technique. the material was characterized by xrd, sem, ftir and uv-vis techniques. xrd results of composites suggested that caco3 particles are found in the amorphous phase of the semi-crystallin...

the aim of this research was to examine the effect of a training interventionprogram on fall-related motor performance in the male elderly with no regularphysical activities. for this purpose, 39 out of 130 participants in screen test wereselected and assigned to training group (n=20) and control group (n=19). subjectsaged between 60 and 70 in experimental were 73.68% and in the control group43...

introduction: caveolin-1 (cav-1) is a scaffolding protein found in special structures of plasma membrane, known as caveolae. cav-1 can regulate many intracellular processes, including signal transmission and cholesterol metabolism. this protein plays an important role in the growth and differentiation of breast tissue and acts as a tumor suppressor gene as well. the aim of this study was to det...

detopping in some plants reduces vegetative growth and increases transporting of photosynthate materials to specific sinks such as seeds. to study the effects of detopping removal and plant density on yield and yield components of faba bean (vicia faba l.), an experiment was carried out as a factorial arrangement based on a randomized complete block design with three replications at farm resear...

some specific and non-specific immune variables of rainbow trout were assessed following vaccination of fish with formalin killed cells (fkc) and fkc containing extra cellular products (ecp) of s. iniae. rainbow trout weighing 80-100 g were vaccinated by intraperitoneal (i.p), dip and oral routes using fkc and fkc plus ecp with or without fround adjuvant (fa) at 16-17°c.antibody titration, lyso...
