Isolates of the human pathogen Mycobacterium tuberculosis recovered from clinical samples exhibit genetic heterogeneity. Such variation may result from the stressful environment encountered by the pathogen inside the macrophage, which is the host cell tubercle bacilli parasitize. To study the evolution of the M. tuberculosis genome during growth inside macrophages, we developed a model of intra...
copper is an essential micronutrient for plant growth which is involved in many metabolic processes. however excessive amounts of copper may cause environmental pollution. with an increase in the contamination of urban areas with heavy metals, more attention should be paid to the role of ornamental plants in removing pollutants from the soils. the effects of heavy metals on the growth parameter...
Many of the virulence factors associated with fulminant group A streptococci (GAS) infection are expressed under in vitro exponential growth conditions. However, the survival of GAS in tissue and intracellularly, as well as colonization of asymptomatic carriers, has been reported for GAS. The bacteria associated with these niches may encounter high-density, low-nutrient-flowthrough conditions t...
the effect of a commercial probiotic (protexin) on growth performance and survival rate in sobaity sparidentex hasta was investigated. 240 fish with average weight of 2.99±0.87g were treated for 10 weeks. this study was carried out in a completely random design with 12 experimental groups, in 4 treatments each with 3 replicates. experimental groups were consisted of four levels of 0.0, 0.5, 1.0...
the effect of plant growth regulator short time treatments ( ga3 and tdz) on the increase of vase life and qualitative traits of alstroemeria cultivars ‘odessa’ and ‘sacramento’ were investigated. cut flowers were treated with 24h pulse treatments which included different concentrations of ga3 and tdz. cut flowers were later held in preservative solution (sucrose 2% +nanosid 2ppm) and then thei...
The efficacy of nets treated with lambda-cyhalothrin, a pyrethroid insecticide, on malaria infection and disease was assessed for the first time at the community level in Anopheles gambiae pyrethroid resistance areas. The study was carried out in northern Côte d'Ivoire, which is an area of kdr resistance. Four pairs of villages were selected and matched according to demographic, sociological, a...
Several eucalypt species are known for their capacity to massively regenerate through seeds in recently burned areas, becoming an ecological problem regions where the is not native. Here we study demography and development of highly dense Eucalyptus globulus wildling populations established one year after a fire test two methods control these populations. We monitored five mixed E. stands acros...
Abstract Introduction and purpose: Intestinal parasitic infections are important threats of immunocompromised patients, especially elderly persons under chemotherapy or those on hemodialysis. Given the presence of patients and ecologic conditions for regeneration and growth of intestinal parasites, the present research aimed at identifying intestinal parasites in these groups of patients, comp...
In this paper, the dynamic simulation for a high pressure regulator is performed to obtain the regulator behavior. To analyze the regulator performance, the equation of motion for inner parts, the continuity equation for diverse chambers and the equation for mass flow rate were derived. Because of nonlinearity and coupling, these equations are solved using numerical methods and the results are ...
Objective: To compare the effects of calculus removal through nephroscopy and holmium laser calculus removal through ureteroscopy on patients with concurrent urinary infection at one side of their upper ureteral calculi. Method: A total of 160 patients admitted to our hospital because of concurrent urinary infection at one side of their upper ureteral calculi were selected from March 2014 to Fe...
