objective: orthodontically induced inflammatory root resorption (oiirr) is an undesirable sequel of tooth movement after sterile necrosis that takes place in periodontal ligament due to blockage of blood vessels following exertion of orthodontic force. this study sought to assess the effect of an angiogenic cytokine on oiirr in rat model. materials and methods: in this experimental animal study...

eye movement desensitization and reprocessing (emdr) process encompasses several nervous system components such as medulla, pons, midbrain, cerebellum, basal ganglia, parietal, frontal and occipital lobes. the role of eye movement (em) has been documented previously in relation with cognitive processing mechanisms. by emdr we can reach some parts of memory which were inaccessible before and als...

Background: Phosphorus is an indispensable element for the growth of animals and plants. There are several environmental problems related to phosphate; therefore, the technical and economic methods of removing phosphate are of great importance. This study evaluated the efficiency of polyaniline/Ni0.5Zn0.5Fe2O4 magnetic nanocomposite in removing phosphate from aqueous environments. Methods: The...

Transformations of dissolved iron and phosphate to particulate material (>0.2 pm) were investigated by adding 55FeC1, and 32P0,3to pH adjusted epilimnetic lake water samples of contrasting ionic strengths and dissolved humic substances (DHS) concentrations. The distributions of these tracers between particulate size fractions in samples without appreciable DHS after 24 h of dark incubation vari...

The purpose of this study was to evaluate the spatial changes of groundwater phosphate concentrations using geostatistical methods based on data from 10 groundwater wells. One of the conventional tools in decision making on the groundwater management is geostatistical method. To evaluate the spatial changes of phosphate concentrations in groundwater, the universal kriging method with cross-vali...

abstract many agricultural researches have been performed to improve soil productivity. nitrogen (n) and phosphorus (p) are essential elements which are utilized by the plants in large amounts. phosphorus can be provided by applying chemical fertilizers. microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this process....

a simple, sensitive and accurate method for spectrophotometric determination of dalacinphosphatehas been established. the method is based on the reduction of atomic absorptioncalcium ion by phosphate. because, there is a phosphate mole in every dalacin mole structureand with measurement of phosphate, dalacin is beyond measurement too. therefore, the reactionbetween acidic hydrolysis products of...
