Microradiography and confocal laser scanning microscopy applied to enamel lesions formed in vivo with and without fluoride varnish treatment
1996
The aim of the present investigation was to combine 2 techniques suitable for lesion characterization: quantitative microradiography (TMR) and confocal laser scanning microscopy (CLSM) on in vivo induced lesions with and without a fluoride varnish (Duraphat(R)) treatment. Orthodontic bands were attached to premolars to be extracted for orthodontic reasons to induce enamel caries on the buccal surfaces. In the caries development part of the study, 1 tooth of each pair received at the start 1 topical application with the fluoride varnish Duraphat(R), the contralateral tooth serving as untreated control. All teeth were extracted after 4 weeks. In the caries progression part, the premolars were…
MITOCHONDRIAL DISORDER SECONDARY TO INFLAMMATION IN POLYMYOSITIS - 2 CASES
1992
National audience; Abstract: Two cases of polymyositis were followed using phosphorus nuclear magnetic resonance spectroscopy. The spectra recorded during remission were normal, but those collected from the gastrocnemius muscle during the active phase of the diseases showed an increased inorganic phosphate level or a decreased phosphocreatine content. The intracellular pH was normal. These findings may be related to an impairment in mitochondrial metabolism secondary to the inflammatory process. Moreover, the fact that the abnormalities observed disappeared after treatment suggests that phosphorus NMR spectroscopy could be used as a non-invasive method in the follow-up of polymyositis, but …
MUSCLE BIOENERGETIC ABNORMALITY IN MYOTONIC-DYSTROPHY - A SECONDARY MITOCHONDRIAL DISORDER
1993
International audience; Abstract: The thenar muscles and gastrocnemius of a patient with myotonic dystrophy were investigated, at rest, by phosphorus nuclear magnetic resonance spectroscopy. A decrease in phosphocreatine level and an increase in inorganic phosphate and phosphodiester levels were found in the gastrocnemius, which was clinically spared, whilst the thenar muscles, which were wasted and affected by myotonia, exhibited only an increased inorganic phosphate level and an elevated pH. These findings were comparable with those found in other muscular disorders, such as Duchenne's and Becker's dystrophies, as well as in limb girdle dystrophy. They suggested that the abnormalities obs…
Análisis de datos cualitativos asistido por ordenador en ciencias de la educación
2010
En el presente trabajo, queremos realizar un análisis de los principales software que se utilizan en el ámbito educativo en las investigaciones que se sitúan en el marco de la investigación cualitativa. Comenzaremos por explicar brevemente en qué consiste este metodología de investigación, para continuar presentando algunos estudios sobre nuestro tema de investigación. Concluiremos con la descripción de los software más utilizados en el análisis de datos que provienen de investigaciones cualitativas. In the present work we try to realize an analysis of principal software that they use in the educational area in the investigations (researches) that situan in the frame of the qualitative rese…
