background: the aim of this study was to evaluate the effects of conjugated lino-leic acid (cla) on apoptosis of tachyzoites of t . gondii , rh strain (type i) and the cyst-forming tehran strain (type ii) in vitro. methods: toxoplasma strains were injected into the peritoneal cavity of balb/c mice. the tehran strain forms cysts in the brain of mice. bradyzoites within the cysts are reactivated ...
background: bovine theileriosis results from infection with obligate intracellular protozoa of the genus theileria . the phylogenetic relationships between two isolates of theileria annulata , and 36 theileria spp . , as well as 6 outgroup including babesia spp . and coccidian protozoa were analyzed using the 18s rrna gene sequence. methods: the target dna segment was amplified by pcr. the pcr...
background and objectives: clostridium perfringens, a gram-positive obligate anaerobic bacterium, is able to form resistant spores which are widely distributed in the environment. c. perfringens is subdivided into five types a to e based on its four major alpha, beta, epsilon and iota toxins. the aim of the present study was cloning and expression of c. perfringens type d vaccine strain epsilon...
agrobacterium rhizogenes (pri), a causative agent of hairy root disease, effectively induces hairy root formation in a variety of plant species. in our study four bacterial strains ar15834, a4, 9435 and c318 and three explants types leaf, stems and roots, were examined. hairy roots were induced from roots, stems and leaf explants. the highest transformation efficiency of 77% was achieved by usi...
measurement of the loads exerted on the limb is a fundamental part of designing of an assistive device, which has been done by using strain gauges or a transducer. although calculation of loads applied on an orthosis coefficients achieved from calibration is a standard way, most of researchers determined the loads based on available equations. therefore, the aim of this research is finding the ...
susceptibility of two wild strains of an. stepliens, collected from kazeroun (st-k.az and bandar-abbas (st-ban), south of iran was compared to fenthion, malathion, temephos , pirimiphos, methyk, deltamethrth, ddt dimilin and etopenprox as larvicides in the laboratory. susceptibility test on the st-kaz strain indicated that this strain is susceptible to the named insecticides i.e. the resistance...
in this study, the strain rate effect on the bending properties of fiber reinforced composites for three types of polymer composites namely phenolic resin reinforced by woven basalt fibers, woven carbon fibers, and woven basalt/ woven carbon fibers at a total volume fraction of approximately 35% has been determined. flexural tests have been conducted at low range of strain rates included 0.03 m...
in this study, the turbulent kinetic energy redistribution process is investigated. to this aim, the direct numerical simulation (dns) of incompressible flow of a newtonian fluid through a channel at a shear reynolds number of reτ = 180 is used to produce a flow data base. then, these data are statistically analyzed. the turbulent kinetic energy redistribution is studied using the pressure-stra...
Bioremoval and bioreduction activities of hydrocarbon (diesel) isolation from environmental samples were studied by the activity of biosurfactant production, and calculating emulsification index, gravimetric, and FTIR analysis along with the estimation of bacterial biomass. Sample from soil near petrol, diesel pumps and water sample from Thesjaswini River near Padannakad, Kasaragod, Kerala, Ind...
In this work, CKCr-6A strain was found to be highly resistant to some toxic heavy metals such as Cr+6, Cr+3, Cu+2, Co+2, Cd+2, Pb+2, Hg+2, U+6, tellurium, and selenite. Herein, high chromate tolerance of an isolated strain is reported with a high minimum inhibitory concentration value of 80,000 mg/L and the ...
