The mechanical properties of the Akers type clasp, bar and frame made by the newly developed Ti-20Cr-0.2Si alloy were studied in order to obtain the indices for designing the cast partial denture base. In the case of the clasp, the bending strength of the Ti-20Cr-0.2Si alloy and pure Ti was lower than that of the Co-Cr alloy. The Ti-20Cr-0.2Si alloy and pure Ti may have the same retentive force...

Ti-Ni-Si-O nanostructures were successfully prepared on Ti-1Ni-5Si alloy foils via electrochemical anodization in ethylene glycol/glycerol solutions containing a small amount of water. The Ti-Ni-Si-O nanostructures were characterized by field-emission scanning electron microscopy (FE-SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and diffuse reflectance absorption spectra....

in the centeral iranian volcanic belt (civb), north-west of shahre-babak, in area of javazm, dehaj and khabr, about 20 plutonic porphyritic tonalitic to granodioritic masses (1-50 km2) are intruded into a varity of rock sequences from eocene to early miocene in age. tonalitic and granodioritic rocks are some part of dehaj-sardoieh belt and having early miocene age. the civb contains intrusive a...

Treatment of CpTiCl3 and Cp2TiCl2 with NaB3H8 affords the titanium(III) hydroborate compounds [CpTiCl(BH4)]2 and Cp2Ti(B3H8), respectively. The former compound arises by means of a new reaction, the metal-induced fragmentation of the B3H8 anion, and can also be made by treating CpTiCl3 with LiBH4. The latter compound has been previously described, but not characterized crystallographically. Bot...

BACKGROUND The outcome of patients with corrected transposition of the great arteries (CTGA) is variably affected by associated intracardiac defects, tricuspid valve competence, and systemic right ventricular (RV) function. The relative importance of these factors in long-term outcome has not been evaluated. METHODS AND RESULTS Since 1958, 40 patients with CTGA were studied to determine risk ...

Cenozoic mantle-derived magmas are widespread on the Tibetan Plateau, and provide evidence for evolution of deep mantle its influence Plateau development. Miocene basalts in Maguan area southeastern have high MgO (9.13–13.10 wt%) Mg# (0.60–0.70) with Ce/Pb (10.6–32.5) Nb/U (43.7–52.9) ratios, similar to those oceanic basalts. Distinct from Eocene-Oligocene potassic Western Yunnan basic volcanic...

INTRODUCTION Changes in combination antiretroviral therapy (cART) throughout childhood challenge the continuity of paediatric HIV treatment. This study aimed to evaluate the prevalence of treatment interruption (TI), including lamivudine (3TC) monotherapy, and the relationship of TI to virologic and immunologic parameters in HIV-infected paediatric patients. METHODS Nested within a prospectiv...

OBJECTIVES This study evaluated cytocompatibility and osseointegration of the titanium (Ti) implants with resorbable blast media (RBM) surfaces produced by grit-blasting or XPEED(®) surfaces by coating of the nanostructured calcium. MATERIAL AND METHODS Ti implants with XPEED(®) surfaces were hydrothermally prepared from Ti implants with RBM surfaces in a solution containing alkaline calcium....

TI significantly reduced HbA1c by20.8% (29.0 mmol/mol) from a baseline of 8.3% (66.8 mmol/mol) compared with TP 20.4% (24.6 mmol/mol) (treatment difference 20.4% [95% CI 20.57, 20.23]; P < 0.0001). More TI-treated subjects achieved an HbA1c £7.0% (53.0 mmol/mol) (38% vs. 19%; P = 0.002). Mean fasting plasma glucosewas similarly reduced in both groups. Postprandial hyperglycemia, based on 7-poin...
