Background:Pseudomonas aeruginosa is a gram negative non facultative bacterium and one of the members of normal flora in different sites of body in healthy humans.this bacterium can resist in fluids and hospital environments for a long time.Pseudomonas aeruginosa has two systems for glucose uptake:a low affinity oxidative pathway and a high affinity phosohorylative pathway.Although the role of ...

to study the effect of nitrogen form and ph of nutrient solution on the uptake and concentration of fe, zn, cu and mn in roots and shoots of spinach plant, a factorial experiment was conducted with two factors including nutrient solution ph in three levels (4.5, 6.5 and 8.0) and nitrate to ammonium ratio of nutrient solution in five levels (100:0, 75:25, 50:50, 25:75 and 0:100). the experiment ...

introduction:myocardial 18f-fdg uptake is highly variable in oncologic whole body 18f-fdg pet/ct studies, ranging from quite intense to minimal distribution. intense or heterogeneous myocardial 18f-fdg uptake is undesirable as it may interfere with the visual or quantitative evaluation of tumoral invasion and metastases in pericardium, myocardium or adjacent mediastinal structures. the diet, as...

the current epidemic of diabetes indicates the need of proper and effective medications that are limited in their potency to have many side effects. thus, introduction of alternative and complementary medicine is now in picture. the main objective of this study was to analyze the rate of glucose transport across cell membrane in yeast cells system in the presence of the ethanolic extract of bru...

statement of problem: since the fluoride releases from materials with the property of releasing fluoride are decreasing gradually, it seems that probably the material rechargeability is more important than their long-term fluoride release. purpose: the objective of this study was to asses the fluoride release and rechargeability of 2 types of fluoride releasing restorative materials, a resin mo...

the aim of this study was to establish and optimise a simplified method of halved grain culture, in order to utilise it to evaluate the ability of isolated sinks (developing wheat grains) in sucrose uptake and conversion (defined by sink strength) under unlimited source conditions. both sucrose uptake and starch synthesis increased linearly over the incubation periods used in this study. a ...

the use of plants to remediate contaminated soil has been the most rapidly developing component in environmental cleansing. although total concentration of heavy metals in soil is used for regulatory review, it also is beneficial to assess the potential for ecosystem impact through a series of bioassays. one commonly used bioassay is seed germination. in current research study effect of contami...

a 65 year-old overweight man with a history of prostate cancer was referred to our nuclear medicine department for bone scanning. anterior projection images showed two small foci of increased radiotracer uptake corresponding to the anterior arcs of the right and left sixth ribs, which were interpreted as suspicious for metastatic involvement. eight months later the patient was referred for foll...

the purpose of this study was to evaluate the effects of nano-silver (ns), calcium chloride (cacl2) and their combinations on gerbera jamesonii ‘carambole’ cut flowers. the experiment was conducted as a completely randomized design (crd) with 10 treatments and four replications, with three flowers in each replication. treatments consisted of 5 mg l-1 ns, 1% and 2% cacl2, 5 mg l-1 ns+ 1% cacl2, ...

nitrate and ammonium forms of nitrogen are being applied to improve plant growth and uptake of other nutrients. given that the effect of application of different nitrate to ammonium ratios accompanied by other fertilizers (i.e. fe, mn and zn) has not been studied on wheat growth as well as uptake of fe, mn and zn, three glasshouse pot studies were conducted with factorial arrangement of treatme...
