introduction: the endemic occurrence of new strains of tuberculosis around the globe has initiated new research on developing diagnostic radiopharmaceutical based on antibiotics. methods:tc-99m labeled streptomycin was prepared using freshly milked 99mtco4- and various concentrations of streptomycin, stannous chloride at various temperatures in high yield radiochemical purity shown by hplc/rtlc...

When Tc-99m-sulfur colloid was introduced as an ideal liver-spleen agent in nuclear medicine, many other types of colloids followed by different manufacturers. They hoped to find a suitable colloidal agent, contrary to sulfur colloid, which is easy to use, and less sensitive to the low contamination of aluminum ions. One of this type of colloid agents, is Tc-99-tin-colloid which is prepar...

introduction: the use of radiopharmaceuticals is a powerful tool in the management of patients with infectious or inflammatory diseases in nuclear medicine. in this study ofloxacin as a second-generation fluoroquinolone is used to design a desired infection imaging agent after labeling with 99mtc via direct labeling. methods: ofloxacin was radiolabeled with 99mtc using different concentrations ...

The topical application of stannous fluoride to the teeth of military personnel has been shown to significantly reduce the dental decay rates of the men so treated. The time spent by the dentist in polishing the teeth for this treatment is so great, however, that these applications could not be given to all Naval personnel. A method whereby the individual polishes his own teeth under supervisio...

Globally, there is growing demand in natural colourants from plants the food, cosmeceutical and pharmaceutical fields. Generally, among various categories of secondary metabolites, carotenoids, anthocyanins, phenols are significant plant-based pigments. Coloured pigments possess remarkable anthocyanin related to anti-oxidant, anti-inflammatory anti-metastatic features. The major objective this ...

Sn1−xErxO2 (x = 0%, 8%, 16%, 24%) micro/nanofibers were prepared by electrospinning combined with heat treatment using erbium nitrate, stannous chloride and polyvinylpyrrolidone (PVP) as raw materials. The target products characterized thermogravimetric analyzer, X-ray diffrotometer, fourier transform infrared spectrometer, scanning electron microscope, spectrophotometer emissivity tester, the ...

Two experienced clinical investigators examined all participating children initially and at the end of the first and second school years. The results from each examiner showed significant reductions in dental caries for the test group at all intervals. In the final results two examiners independently observed caries reductions of 33% and 43% in DMFS scores for the group using the stannous fluor...

The aim of this research is to develop new mordants and a wide range of colors for natural dyeing of silk. In this study, two new erbium(ΙΙΙ) complexes, [Er(AO)(H2O)7](OAc)3 and [Er(AMH)(H2O)6](OAc)3 (AO = acridine orange, AMH = azomethine-H, and OAc = acetate anion), were synthesized, characterized and used as a mordant for the natural dyeing of silk yarns with an aqueous extract of green waln...
