Yttrium oxide nanoparticles prevent photoreceptor death in a light-damage model of retinal degeneration.

Only registered users can translate articles

Photoreceptor (PR) cells are prone to accumulation of reactive oxygen species (ROS) and oxidative stress. An imbalance between the production of ROS and cellular antioxidant defenses contributes to PR degeneration and blindness in many different ocular disease states. Yttrium oxide (Y2O3)

Three-year safety and visual acuity results of epimacular 90 strontium/90 yttrium brachytherapy with bevacizumab for the treatment of subfoveal choroidal neovascularization secondary to age-related macular degeneration.

OBJECTIVE To evaluate the long-term safety and visual acuity outcomes associated with epimacular strontium 90 brachytherapy combined with intravitreal bevacizumab for the treatment of subfoveal choroidal neovascularization because of age-related macular degeneration. METHODS Thirty-four

Basophilic round bodies in gastric biopsies little known by pathologists: iatrogenic yttrium 90 microspheres deriving from selective internal radiation therapy.

Only registered users can translate articles

Selective internal radiation therapy is a relatively new technique that irradiates primary and metastatic liver cancer using yttrium 90 microspheres. Increasing reports have shown this to be a useful treatment for unresectable primary hepatocellular carcinoma and others metastases from colon, lung,

Significant impact of transient deterioration of renal function on dosimetry in PRRT.

Only registered users can translate articles

Peptide receptor radionuclide therapy (PRRT), with (90)Y-DOTATOC and (177)Lu-DOTATATE as most clinically used radiopeptides, is widely used in the management of metastatic neuroendocrine tumors. With respect to radiation dosimetry, the kidneys are the critical organ for (90)Y-DOTATOC. Renal

OBJECTIVE To report the optical coherence tomography (OCT) and fundus fluorescein angiography (FFA) results of the Macular Epiretinal Brachytherapy in Treated Age-Related Macular Degeneration study. METHODS Prospective, multicenter, interventional, noncontrolled clinical trial. METHODS Fifty-three

Histological Comparison of Kidney Tissue Following Radioembolization with Yttrium-90 Resin Microspheres and Embolization with Bland Microspheres.

Only registered users can translate articles

BACKGROUND Intra-arterial brachytherapy with yttrium-90 (90Y) resin microspheres (radioembolization) is a procedure to selectively deliver high-dose radiation to tumors. The purpose of this research was to compare the radioembolic effect of 90Y-radioembolization versus the embolic effect of bland

Histological changes in nontumoral liver secondary to radioembolization of hepatocellular carcinoma with yttrium 90-impregnated microspheres: report of two cases.

Only registered users can translate articles

Transarterial radioembolization (TARE) with yttrium-90 is a minimally invasive locoregional therapy for hepatocellular carcinoma (HCC), and involves selective delivery of glass or resin microspheres impregnated with radioactive yttrium-90 into small arteries preferentially supplying the tumor for

Treatment of cystic craniopharyngiomas with yttrium-90 colloid solution.

Only registered users can translate articles

The authors analyzed long-term follow-up data to assess the value of intracavitary irradiation with stereotactically implanted beta-emitting radioisotope (90)Y-silicate colloid for the treatment of craniopharyngiomas. Fifty-seven craniopharyngiomas in 42 patients were selected for retrospective

Stereotactic intracavitary irradiation of cystic craniopharyngiomas with yttrium-90 isotope.

Only registered users can translate articles

The authors analyzed data from nearly 30-year follow-up period to assess the value of intracavitary irradiation with stereotactically implanted beta-emitting radioisotope yttrium- 90 (90Y) silicate colloid for the treatment of cystic craniopharyngiomas. Seventy-three cysts in 60 patients were

Treatment of pigmented villonodular synovitis of the knee with yttrium-90 silicate: prospective evaluations by arthroscopy, histology, and 99mTc pertechnetate uptake measurements.

Only registered users can translate articles

The diffuse form of pigmented villonodular synovitis of eight knee joints of eight patients was treated by intra-articular injection of 185 MBq yttrium-90 silicate (90Y). Six patients had a recurrence of disease after one or two surgical synovectomies. After treatment with 90Y once or twice four
