Hookworm infection is associated with growth delay and iron deficiency anemia in developing countries. A series of experiments were designed in order to test the hypothesis that host dietary iron restriction mediates susceptibility to hookworm infection using the hamster model of Ancylostoma ceylanicum. Animals were maintained on diets containing either 10 ppm iron (iron restricted) or 200 ppm ...

BACKGROUND Superparamagnetic iron oxide nanoparticles are attractive materials that have been widely used in medicine for drug delivery, diagnostic imaging, and therapeutic applications. In our study, superparamagnetic iron oxide nanoparticles and the anticancer drug, doxorubicin hydrochloride, were encapsulated into poly (D, L-lactic-co-glycolic acid) poly (ethylene glycol) (PLGA-PEG) nanopart...

progressive usage of medicinal plants has necessitated their mass production using the minimum amounts of chemical inputs. to find out the effects of urea and pelleted animal manure and some micronutrients on yield and its components in pumpkin, a split plot experiment based on rcbd with three replicates was conducted at the research farm of abouraihan campus, university of tehran in 2011. the ...

objective: in order to study the effect of different concentrations of iba hormone on rooting of olive cuttings in spring and winter of 2012-2013 in a greenhouse in jiroft, iran. methods: a split-plot experiment was conducted on the basis of a randomized complete block design in which hardwood cuttings of one-year-old olive plants cv. manzanilla with the diameter of 0.7-1 cm were used. the main...

pumpkin is one the most important cultivated medicinal plants. because of high quality oil it uses as edible and herbal medicine. to find out the effects of different rates of pelleted animal manure and urea levels and some micronutrients on morphophysiological characteristics and oil yield of medicinal pumpkin, a split plot experiment based on rcbd with three replicates was conducted at the re...

background: no study has been conducted on iron requirements of broiler breeder hens until now. objectives: the purpose of the present study was to determine the iron requirement of broiler breeder hens using nonlinear models. methods: forty eight (cobb 500) broiler breeder hens were individually placed in galvanized wire cages. in order to depletion of hens iron reserved, hens were offered a s...

The impact of phenylphthalamic acid (PPA) rates including 0 (PPA0), 1000 (PPA1000), 2000 (PPA2000) or 3000 (PPA3000) mg L-1 and perfect fertilizer rates including 0 (PF0), 100 (PF100), 200 (PF200) and 300 (PF300) mg L-1 was studied on vegetative and reproductive growth of ornamental pep...

High-touch environmental surfaces are important in the spread of many nosocomial pathogens. Although such surfaces are routinely disinfected, the testing and label claims of many common disinfectants do not reflect the realities of field use. A study was conducted to determine the influence of several crucial factors on the action of disinfectants in general, and to assess the killing efficienc...
