to study the effect of type and different nitrogen fertilizers on controlling egyptian broomrape, field and greenhouse studies based on randomized complete block with three replications, were conducted at ferdowsi university of mashhad. greenhouse study treatments were consisted of ammonium nitrate, ammonium sulfate and urea each of which applied at four rates (75, 150, 300 and 350 kg/ha). fiel...

purpose: to design and manufacture iodine 125 radioactive plaques which can be used in patients with ocular melanoma, and to evaluate the efficacy of plaques in an animal model. methods: this prospective basic study was performed in collaboration with farabi hospital and tehran atomic energy agency. the iodide 125 plaques were designed and manufactured based on the collaborative ocular melanoma...

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 ...

The absence of TSH-stimulated radioiodide uptake in differentiated thyroid cancer is associated with a high recurrence rate and reduced survival. We studied regulation of the sodium/iodide symporter gene in human papillary thyroid cancer cell lines (BHP) and primary human thyroid cells. BHP cells expressed very low levels of sodium/iodide symporter mRNA and did not concentrate iodide, but iodid...

In a preceding report, we showed evidence that thyrotropin (TSH) stimulates Ca2+ efflux from mouse thyroid gland and that TSH stimulation of Ca2+ efflux is inhibited by acute administration of excess iodide to mice fed a low iodine diet (Hashizume et al., 1984). The observations suggested that iodide inhibits Ca2+ efflux through an inhibition of TSH-sensitive adenylate cyclase activity. We foun...

Background: Lactoferrin is a glycoprotein with a molecular weight of 80 kDa, as a member of the transferring family. In recent investigations the important biological properties such as anti microbial, antiviral and anticancer activity of lactoferrin were studied. In the present study, the effect of antitumor induced by lactoferin was evaluated on stomach cancer cell AGS. Materials and Methods...

Fully evaporated solar cells using methylammonium iodide (MAI)-based perovskites can reach power conversion efficiencies exceeding 20%. An important point to advance perovskite photovoltaics is ensure reproducibility from batch batch. Sublimation control of organic ammonium halides critical in achieving this for cells. Herein, a reproducible procedure the coevaporation PbI2 and MAI based on an ...

Sodium iodide was given in increasing doses to mentally defective children with normal thyroid function. Maximal suppression of iodine-131 uptake was achieved with 1500 to 2000 micrograms of iodide per square meter of body surface per day, but quickly rebounded when iodide was discontinued. This minimal effective dose is important if countermeasures against fallout are employed.
