Introduction Proton electron double resonance imaging (PEDRI) is a wellestablished method for imaging free radicals in biological samples and small animals [ 11. The EPR resonance of the free radical under study is irradiated during the acquisition of an MR image; the image intensity in parts of the sample containing free radical is altered by the Overhauser effect. In order to reduce the EPR i...

a practical and new method for the synthesis oxindole substituted pyrrolo[2,3-d]pyrimidines by the condensation of isatin, acetophenone and 6-amino-uracil under ultrasound irradiation conditions at 60 °c was described. the reaction was developed via a sequential tandem process to afford the oxindole substituted pyrrolo[2,3-d]pyrimidines in good to excellent yields. all reactions performed effic...

The effects of microwave plasma induction and reduction on the promotion of the carbothermal reduction of iron oxides (α-Fe2O3, γ-Fe2O3, and Fe3O4) are investigated using in situ emission spectroscopy measurements during 2.45 GHz microwave processing, and the plasma discharge (such as CN and N2) is measured during microwave E-field irradiation. It is shown that CN gas or excited CN molecules co...

Radiation is an important therapy for cancer with many benefits; however, its side effects, such as impaired wound healing, are a major problem. While many attempts have been made to overcome this particular disadvantage, there are few effective treatments for impaired wound healing in an X-ray-irradiated field. One reason for this deficiency is the lack of experimental models, especially anima...
