| 1 | Low-level laser therapy enhances the number of osteocytes in calvaria bone defects of ovariectomized rats显示文摘Background : Osteoporosis can make bone repair difficult. Low-level laser therapy( LLLT) has been shown to be a promising tool for bone neoformation. This study aimed to analyze the effect of LLLT on calvaria bone defects of ovariectomized rats using stereology. Methods : Fifty-four Wistar rats were subjected to bilateral ovariectomy, and bone defects were created in calvaria after 150 days. The animals were divided into nine groups(n = ?6 per group), and 24 hours after the bone defects were created they received three, six or 12 sessions of LLLT at 0, 20 or 30 J/cm 2, using a 780-nm low-intensity GaAlAs laser. One-way ANOVA followed by Tukey ' s post hoc test was used for data processing. A difference of P < 0.05 was considered statistically significant. The parameters evaluated were osteocyte density( Nv_(ost)), total osteocyte number( Nto ost), trabecular surface density( Sv_t), and trabecular surface area( Sa_t). Results : Data obtained showed that Nto ost, Sv t, and Sa t in group G2 rats were significantly different from G1(0 J/cm^2)( P < 0.05). Compared to group G4, G5 presented higher values for the parameters Sv t and Sa t, and G6 presented significantly higher values for almost all the analyzed parameters( Nv _(ost), Nto_(ost), Sv_t, and Sa t)( P < 0.05). Compared to group G7, G8 showed a higher value only for the parameter Sa t, and G9 showed significantly higher values for parameters Nv ost, Nto ost, Sv_t, and Sa_t. Conclusion : We conclude that LLLT stimulated bone neoformation and contributed to an increase in the total number of osteocytes, especially with a laser energy density of 30 J/cm^2 given for six and 12 sessions. | Priscilla Hakime Scalize Luiz Gustavo de Sousa Lígia Maria Napolitano Goncalves Dimitrius Leonardo Pitol Marcelo Palinkas Antonio Augusto Coppi Mariah Acioli Righeti Vitória Ricardo Karina Fittipaldi Bombonato-Prado Simone Cecílio Hallak Regalo Selma Siessere | 2019 | Animal Models and Experimental Medicine2019，2，1： | 2 |
| 2 | Science Letters:Quantification of Helicobacter pylori levels in soil samples from public playgrounds in Spain显示文摘Helicobacter pylori are ubiquitous Gram-negative bacteria with a high estimated level of infection in the world populations, but a majority of the infected persons are asymptomatic. This pathogen has been classified by the World Health Organization as a class I carcinogen and recognized as the causal agent of most peptic ulcers and chronic gastritis that might lead to stomach cancer. Although not all the transmission pathways of these bacteria into humans have been properly identified, enough data have suggested that the oral-oral or fecal-oral ones are the main infection routes. Helicobacter pylori have been detected in non-treated water and in drinking water, which suggested that water might be an important infection source. As childhood is the critical period of infection, the aim of the present work was to examine the presence of Helicobacter pylori in soil samples from public playing areas of Spanish parks. | Leonardo Martín PéREZ Francesc CODONY Daniela LóPEZ LEYTON Mariana FITTIPALDI Bárbara ADRADOS Jordi MORATó | 2010 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2010，11，1： | 2 |
| 3 | Femtosecond laser deposition of TiO_2 nanoparticleassembled films with embedded CdS nanoparticles显示文摘Based on the normal pulsed laser ablation method,femtosecond pulsed laser deposition(fs-PLD)is adopted in vacuum for the production of TiO2nanoparticle-assembled films.We study the morphology and electronic characteristics of TiO2nanoparticle-assembled films deposited at different oxygen background gas pressures from high vacuum(~10-4Pa)to 100 Pa and different deposition time.Our results show that TiO2nanoparticle-assembled films obtained in high vacuum present both a mixture with rutile phase and anatase phase and a pure rutile phase.At the same time,there are more mesoporous structures in the film after annealing,which is beneficial for the enhancement of photocatalytic activity.In water splitting experiment,part of the TiO2nanoparticle-assembled films embedded with a small mass fraction of CdS nanoparticles(~5%)present an interesting photocurrent enhancement with a maximum value of^0.2mA/cm2under a solar simulator. | 倪晓昌 桑丽霞 张洪杰 Anoop Kiliyanam-kandy Salvatore Amoruso 王宣 Rosalba Fittipaldi 李彤 胡明列 徐丽娟 | 2014 | Optoelectronics Letters2014，10，1： | 2 |
