We have grown epitaxial Fe-doped TiO2 rutile films on rutile TiO2(110) substrates, and have explored the resulting compositional, structural, morphological and magnetic properties. Clusters of mixed TiO2 rutile and Fe3O4 form on the surface of a continuous rutile epitaxial film during growth. Room-temperature ferromagnetism is observed, and is associated with the formation of secondary phase Fe3O4 rather than a true diluted magnetic oxide semiconductor.

The epitaxial growth of CeO2 films on SrTiO3(001) has been investigated over a wide range of growth parameters using oxygen-plasma-assisted molecular beam epitaxy. The lattice mismatch for CeO2 on SrTiO3(001) is 2.0% (compressive) if the film nucleates with a 45° rotation about [001] relative to the substrate (i.e., CeO2(001)‖SrTiO3(001) and CeO2[110]‖SrTiO3[100]). Pure-phase, single-crystalline epitaxial films of CeO2(001) with the above epitaxial relationship readily grew on SrTiO3(001) for substrate temperatures ranging from 550 to 700 °C. However, small amounts of (111) and (220) minority orientations also nucleated at the higher substrate temperatures. In addition, the film surface was observed to become progressively smoother with increasing substrate temperature due to more extensive island agglomeration. The highest-quality film surface grown at 700 °C is unreconstructed and oxygen terminated.

Objective• To evaluate serial changes in renal function by investigating various clinical factors after radical nephrectomy (RN). Patients and Methods• The study population consisted of 2068 consecutive patients who were treated at multiple institutions by RN for renal cortical tumour without metastasis between 1999 and 2011. • We measured the serial change in estimated glomerular filtration rate (eGFR) and clinical factors during a 60-month follow-up period.• The changes in eGFR over time were analysed according to baseline eGFR (eGFR ≥60 and 15-59 mL/min/1.73m 2 ) using a linear mixed model.• The independent prognostic value of various clinical factors on the increase in eGFR was ascertained by multivariate mixed regression model. Results• Overall, there was a subsequent restoration of renal function over the 60 months.• The slope for the relationship between the eGFR and the time since RN was 0.082 (95% confidence interval [CI] 0.039-0.104; P < 0.001) and 0.053 (95% CI 0.006-0.100; P = 0.038) in each baseline group, indicating that each month after RN was associated with an increase in eGFR of 0.082 and 0.053 mL/min/1.73m 2 , respectively. • When we analysed renal function based on various factors, postoperative eGFR of patients with diabetes mellitus, old age (≥70 years) or a preoperative eGFR of <30 mL/min/ 1.73 m 2 , was decreased or maintained at a certain level without any improvement in renal function.• Preoperative predictors of an increase in eGFR after RN were young age, no DM, no hypertension, a preoperative eGFR of ≥30 mL/min/1.73m 2 and time after surgery (≥36 months). Conclusions• Renal function recovered continuously during the 60-month follow-up period after RN.• However, the trends in functional recovery change were different according to various clinical factors and such information should be discussed with patients when being counselled about their treatment for renal cell carcinoma (RCC).
