Synthesis of MgAl2O4 whiskers by an oxidation-reduction reaction
Journal of the American Ceramic Society, 1995Co-Authors: Shinobu Hashimoto, Akira YamaguchiAbstract:Magnesium orthosilicate (forsterite) whiskers were synthesized by an oxidation-reduction reaction in the present investigation. These whiskers were rectangular parallelepipeds, with long sides in a cross-Sectional View from two to ten times as long as the short sides, and measuring from several micrometers to 200 μm wide and ∼15 mm in the elongated direction. The Mg2SiO4 elongation was on the c-axis. The growth mechanism of the whiskers was investigated on the basis of chemical thermodynamics, and the present study revealed that the Mg2SiO4 whiskers grew by a VS (vapor-solid) mechanism.

Optical Incoherence Tomography: a method to generate tomographic retinal cross-sections with non-interferometric adaptive optics ophthalmoscopes
Biomedical optics express, 2020Co-Authors: Pedro Mecê, Elena Gofas-salas, Michel Paques, Kate Grieve, Serge MeimonAbstract:We present Optical Incoherence Tomography (OIT): a completely digital method to generate tomographic retinal cross-sections from en-face through-focus image stacks acquired by non-interferometric imaging systems, such as en-face adaptive optics (AO)-ophthalmoscopes. We demonstrate that OIT can be applied to different imaging modalities using back-scattered light, including systems without inherent optical sectioning and, for the first time, multiply-scattered light, revealing a distinctive cross-Sectional View of the retina. The axial dimension of OIT cross-sections is given in terms of focus position rather than optical path, as in OCT. We explore this property to guide focus position in cases where the user is "blind" focusing, allowing precise plane selection for en-face imaging of retinal pigment epithelium, the vascular plexuses and translucent retinal neurons, such as photoreceptor inner segments and retinal ganglion cells, using respectively autofluorescence, motion contrast and split detection techniques.

a cross Sectional View of radiation dose fractionation schemes used for treating painful bone metastases pbm within veterans health administration s radiation oncology centers
Journal of Clinical Oncology, 2016Co-Authors: George Dawson, Ignat Glushko, Kevin Greener, Michael P HaganAbstract:10110Background: The use of single fraction (SF) radiotherapy in the treatment of PBM in the United States is now gaining clinical acceptance, especially at large institutional levels. In this cros...

a cross Sectional View of radiation fractionation schemes used for painful bone metastases pbm cases within the veterans health administration radiation oncology centers
Journal of Clinical Oncology, 2015Co-Authors: George Dawson, Ignat Glushko, Michael P HaganAbstract:177 Background: Though the use of single fraction (SF) radiotherapy in the treatment of PBM is an integral component of frontline palliative radiotherapy in Canada and Europe ((Popovic - Radiotherapy and Oncology 111 (2014) 11–17), its use in the United States is only now gaining clinical acceptance. Recently, VHA Radiation Oncologists reported that roughly 76% offer SF to patients with a limited life expectancy (J Palliat Med. 2014 Nov;17(11):1221-5). In this cross-Sectional report, we examine the actual dose fractionation schemes used for PBM cases by VHA Radiation Oncologists. Methods: METHOD: An electronic request was sent to 38 of 39 active VHA RO centers asking them to provide the radiation dose fractionation scheme used in the last 10 of their cases of PBM - (International Classification of Diseases (ICD) 198.5 - secondary malignancy of bone and or bone marrow). The study period: 03/01/2015 to 03/16/2015; Response rate: 100%. Data was provided for 382 cases . The survey results were divided by regi...

Bladder injuries after external trauma: 20 years experience report in a population-based cross-Sectional View
World Journal of Urology, 2013Co-Authors: Bruno Monteiro Tavares Pereira, Caio César Citatini Campos, Thiago Rodrigues Araujo Calderan, Leonardo Oliveira Reis, Gustavo Pereira FragaAbstract:Objectives Report 20 years experience of bladder injuries after external trauma. Methods Gender, age, mechanism/location of damage, associated injuries, systolic blood pressure (SBP), Revised Trauma Score (RTS), Injury Severity Score (ISS), Trauma Injury Severity Score (TRISS), complications, and length of stay (LOS) were analyzed in a prospective collected bladder injuries AAST-OIS grade ≥II database (American Association for the Surgery of Trauma Organ Injury Scaling) from 1990 to 2009 in a trauma reference center. Results Among 2,575 patients experiencing laparotomy for trauma, 111 (4.3 %) presented bladder ruptures grade ≥II, being 83.8 % ( n = 93) males, mean age 31.5 years old (±11.2). Blunt mechanism accounted for 50.5 % ( n = 56)–motor vehicle crashes 47.3 % ( n = 26), pedestrians hit by a car (29.1 %). Gunshot wounds represented 87.3 % of penetrating mechanism. The most frequent injury was grade IV (51 patients, 46 %). The mean ISS was 23.8 (±11.2), TRISS 0.90 (±0.24), and RTS 7.26 (±1.48). Severity (AAST-OIS), mechanism (blunt/penetrating), localization of the bladder injury (intra/extraperitoneal, associated), and neither concomitant rectum lesion were related to complications, LOS, or death. Mortality rate was 10.8 %. ISS > 25 ( p = 0.0001), SBP
