Poly(L-lactic acid) microspheres loaded with holmium-166 acetylacetonate (166Ho-PLLA-MS) are a novel microdevice for intra-arterial radio-embolization in patients with unresectable liver malignancies. The neutron activation in a nuclear reactor, in particular the gamma heating, damages the 166Ho-PLLA-MS. The degree of damage is dependent on the irradiation characteristics and irradiation time i...

(166)Ho-EDTMP is a major therapeutic agent which is widely used in bone palliation therapy. In this study, a (166)Ho-EDTMP complex was prepared successfully using an in-house synthesized EDTMP ligand and (166)HoCl(3). Ho-166 chloride was obtained by thermal neutron irradiation (1 Ã 10(13) ncm(â2)s(â1)) of natural Ho(NO(3))(3) samples (specific activity = 3â5 GBq/mg), dissolved in acidic media. ...

In this presented work, pure and holmium, niobium, holmium–niobium co-doped titanium dioxide nanopowders were synthesized by the sol–gel method. Their morphological, structural, optical, photocatalytic properties analyzed scanning electron microscopy, X-ray diffraction, UV–visible spectrophotometer. The activities of examined using ultraviolet light. results have shown that doping both with a s...

The absorption spectra of the 4f electron transitions of neodymium, praseodymium, holmium and erbium complexes with fleroxacin in the presence of cetylpyridinium chloride were studied by normal and derivative spectrophotometry. Their molar absorptivity at the maximum absorption bands are about 5.3 (at 571 nm) times greater for neodymium, 2.8 (at 483 nm) times greater for praseodymium, 12.6 (at ...
