transferrin acts as a vehicle for iron transportation between the absorption, storage and utilization sites in the body and, besides iron, its two highaffinity iron-binding site are capable of binding to 29 other elements. in physiological and pathophysiological conditions, transferrin’s properties are different and close attention to these properties is required. for further investigation for ...
in west africa and nigeria in particular, many virgin plants are still waiting to be evaluated for their medicinal importance. claims of plants with folk medicinal applications need to be evaluated and verified. gomphrena celosioides (family – amaranthaceae) is a weed grown in lawns and the biological activity of the extract had earlier been established. in the present study, the plant was coll...
background and objective : salmonellosis can be acquired through consumption of infected raw or undercooked eggs. the aim of this study was isolation and identification of salmonella spp from the eggshells and the egg contents samples of tabriz retails. methods : a total number of 150 samples of eggs were analyzed for the presence of salmonella spp. using conventional culture method and multipl...
background kelussia odoratissima mozaff. is one of the newest genera of umbelliferae which is represented by only one species. this sweet-smelling, self-growing monotypic medicinal plant is endemic to a restricted area in west of iran and is locally called karafse-koohi. the aerial parts of the plant are commonly used as a popular garnish and a sedative medicinal plant. there are several report...
the rhizome of anemarrhena asphodeloides is used as food and traditional chinese medicine for its hypoglycemic effect. the aim of this study was to investigate the isolation, purification and hypoglycemic activity of anemaran as the active component. the influence factors (isolation duration, ratio of residuals to water and extracting times) during the isolation process were evaluated. the opti...
background: there are eight taxus species and two hybrids in the world and taxus baccata l. (european yew) is the single representative in iran. until now, a large number of taxoids possessing different skeleton systems, as well as lignans, flavonoids, steroids and sugar derivatives have been isolated from various taxus species. taxoids are highly oxygenated diterpenes isolated from different s...
ornithobacterium rhinotracheale (ort), a species of bacteria, is known to be associated with respiratorydisease, growth retardation, mortality and decreased egg production. the aim of the present study was todetermine seroprevalence of the infection and to identify the microorganism by bacteriological and molecularmethods. in this study, 460 serum samples and also 290 tracheal swabs were collec...
elaeagnus angustifolia has many potential applications in drugs, detergents, perfumes, herbal teas and show various biological and pharmacological activities, such as anti-inflammatory, antipyretic and other effective treatment of disease. gallic acid (ga) and its derivative methyl gallate (mg) are well studied plant phenolics. they have exhibited anticancer effects in several cancer cell lines...
bioleaching is the extraction of metals from their ores through the use of microorganisms. inthis process, the use of native bacteria leads to achieve more yields of metals. so, in the presentstudy, native sulfur-oxidizing bacterium in potentiality of uranium extraction was isolated fromghachin mine in iran and identified by partial gene sequencing. for this purpose, the watersamples were colle...
several species of magnetotactic bacteria have been discovered recently. these bacteria synthesize intracellular magnetic nanoparticles in specific sizes and shapes and arrange them in chains. these particles called magnetosomes and can be used for drug-delivery, cell-targeting and hyperthermia. magnetotactic bacteria navigate along the magnetic field; this process is known as ‘magnetotaxis’ wh...
