A nonaqueous synthetic route for the preparation of a regular crystalline yttria mesostructure is presented. The reaction between yttrium alkoxides and benzyl alcohol results in the formation of a highly ordered lamellar nanocomposite consisting of yttria layers with a confined thickness of about 0.6 nm, separated from each other by organic layers of intercalated benzoate molecules. Doping with...

Abstract
 Objective: 
 Somatostatin analogs (SSA) are used in treating low-grade neuroendocrine tumors, mainly because of their antiproliferative effect. 68Ga tetraazacyclododecantetraacetic acid-DPhe1-Tyr3-octreotate (DOTATATE) PET/CT as somatostatin receptor imaging has been widely recent years. However, there conflicting publications the literature, although guidelines for disconti...

This paper reports on the supercontinuum generation in yttrium orthosilicate bulk crystal and 6-mm-long ion implanted planar waveguide. The waveguide is fabricated by 6 MeV oxygen ions implantation with fluence of 5 × 10(14) ions/cm(2) at room temperature. The yttrium orthosilicate bulk crystal and waveguide are pumped using a mode-locked Ti:Sapphire laser with a center wavelength of 800 nm. Th...

Pain is a complex sensory experience resulting from the activity of a network of brain regions. However, the functional contribution of individual regions in this network remains poorly understood. We delivered single-pulse transcranial magnetic stimulation (TMS) to the contralateral primary somatosensory cortex (S1), secondary somatosensory cortex (S2) and vertex (control site) 120 msec after ...

Mixtures of yttrium acetate hydrate (Y(O2CCH3)3?4H2O) and aluminum formate hydrate (Al(O2CH)3?3H2O in H2O) or yttrium isobutyrate (Y[O2CCH(CH3)2]3) and aluminum isobutyrate (Al[O2CCH(CH3)2]3) in tetrahydrofuran were used as precursors to process yttrium aluminum garnet (YAG, Al5Y3O12) fibers. The pyrolytic decomposition patterns of Al(O2CH)3?3H2O, Y(O2CCH3)3?4H2O, and a [3Y(O2CCH3)3?4H2O/5Al(O2...

Fibrosing mediastinitis is underdiagnosed because of the nonspecific character of the presenting symptoms. The endobronchial findings obtained via flexible bronchoscopy are not defined in the literature. We describe 3 cases of fibrosing mediastinitis, most likely caused by histoplasmosis. All 3 patients presented with hemoptysis and were found to have tracheobronchial concentric narrowing, seve...

OBJECTIVE To consider the question: How strong is the evidence in favour of yttrium synovectomy in chronic knee arthritis in patients with rheumatoid arthritis in comparison with placebo and intra-articular steroid treatment? METHODS A systematic review of the literature was performed using Medline and the Embase database. RESULTS Initially, seven papers were identified, but only two met th...
