International Journal of Clinical Medicine (IJCM) , 2014, DOI: 10.4236/ijcm.2014.511086
Abstract:

The use of Ultrasonography is very important in the diagnosis of several conditions of the body, particularly the muscular skeletal system, and it is grateful as a very valuable method of exploration complementary of image. The fascitis to plant is frequent in the corridors. The use of the Ultrasonography is with the objective of visualizing the presence and the magnitude of the fascitis plant in a fond corridor and to know the sensibility of the Ultrasonography of High Resolution in the diagnosis of this lesion. This study in a fond corridor, symptomatic of affection to plant fascitis, in this case severe increase of low ecogenicidad of the insert was verified in the calcaneus of the fascia to plant of the tweeted right with bony proliferation sketch at that level, in contrast with the one against-lateral. The Ultrasonography demonstrated its sensibility in the diagnosis of the fascitis to plant that it is recognized as the most frequent affection that is presented in corridors related with the occasional incursion of career or to its systematic practice associated with factors external they predispose.

Abstract: the degenerative joint disease, also known as osteoarthrosis affects to 10% of elderlies aged 60. it is mainly characterized by pain in the involved joint, crepitation, morning stiff and a progressive limitation of movement of that joint leading to a partial or total wear of articular cartilage. the treatment of the knee osteoarthrosis is a great challenge. the recent advances in use of regenerative medicine suggest that adult stem cells could represent a promisor alternative in the treatment of this entity. in a female patient aged 61 presenting with knee osteoarthrosis authors placed a percutaneous implant of autologous mononuclear cells mobilized to peripheral blood by granulocyte colony-stimulating factor achieving a fast clinical and radiological improvement. this result suggests that the procedure used is a feasible, simple, safe and less expensive method for treatment of articular degenerative lesions.

Structural and Magnetic Properties of Monophasic Maghemite (γ-Fe2O3) Nanocrystalline Powder  [PDF]
Juan Adrián Ramos Guivar, Arturo Isaías Martínez, Ana Osorio Anaya, Luis De Los Santos Valladares, Lizbet León Félix, Angel Bustamante Dominguez
Advances in Nanoparticles (ANP) , 2014, DOI: 10.4236/anp.2014.33016
Abstract:
Structural and magnetic studies of monophasic maghemite (γ-Fe2O3) magnetic nanocrystallites (MNCs) synthesized by the co-precipitation chemical route are reported in this paper. For the synthesis, a starting precursor of magnetite (Fe3O4) in basic medium was oxidized at room temperature by adjusting the pH = 3.5 at 80°C in an acidic medium without surfactants. X-ray diffraction (XRD) pattern shows widened peaks indicating nanometric size and Rietveld Refinement confirms only one single-phase assigned to γ-Fe2O3 MNCs. High Resolution Transmission Electron Microscopy (HR-TEM) demonstrates the formation of nanoparticles with diameter around D ≈ 6.8 ± 0.1 nm which is in good agreement with Rietveld Refinement (6.4 ± 1 nm). A selected area electron diffraction pattern was carried out to complement the study of the crystalline structure of the γ-Fe2O3 MNCs. M(H) measurements taken at different temperatures show almost zero coercivity and remanence indicating superparamagnetic domain and high magnetic saturation.

Abstract: Land abandonment is one of the most powerful global change drivers in developed countries where recent rural exodus has been the norm. Abandonment of traditional land use practices has permitted the colonization of these areas by shrub and tree species. For fleshy fruited species the colonization of new areas is determined by the dispersal assemblage composition and abundance. In this study we showed how the relative contribution to the dispersal process by each animal species is modulated by the environmental heterogeneity and ecosystem structure. This complex interaction caused differential patterns on the seed dispersal in both, landscape patches in which the process of colonization is acting nowadays and mature woodlands of Juniperus thurifera, a relict tree distributed in the western Mediterranean Basin. Thrushes (Turdus spp) and carnivores (red fox and stone marten) dispersed a high amount of seeds while rabbits and sheeps only a tiny fraction. Thrushes dispersed a significant amount of seeds in new colonization areas, however they were limited by the presence of high perches with big crop size. While carnivores dispersed seeds to all studied habitats, even in those patches where no trees of J. thurifera were present, turning out to be critical for primary colonization. The presence of Pinus and Quercus was related to a reduced consumption of J. thurifera seeds while the presence of fleshy fruited shrubs was related with higher content of J. thurifera seeds in dispersers’ faeces. Therefore environmental heterogeneity and ecosystem structure had a great influence on dispersers feeding behaviour, and should be considered in order to accurately describe the role of seed dispersal in ecological process, such as regeneration and colonization. J. thurifera expansion is not seed limited thanks to its diverse dispersal community, hence the conservation of all dispersers in an ecosystem enhance ecosystems services and resilience.

Abstract: Las anomalías dentomaxilofaciales comprenden las alteraciones de crecimiento, desarrollo y fisiologísmo de los componentes anatómicos que conforman el sistema estomatognático. Se realizó un estudio descriptivo y transversal en 150 ni os de 9 a 14 a os de edad, de las escuelas atendidas en la Clínica Estomatológica "Antonio Briones Montoto" de Pinar del Río, en el período comprendido entre enero de 2008 y julio de 2009, con el objetivo de identificar la prevalencia de anomalías dentomaxilofaciales según las variables seleccionadas y el comportamiento según los antecedentes patológicos individuales. La muestra se seleccionó a través de un muestreo aleatorio estratificado proporcional al tama o de los estratos. Los ni os fueron examinados en sus aulas, con luz natural, usando depresores linguales. La información recogida fue recopilada en una base de datos mediante Microsoft Excel, y se procesó por el programa estadístico Statistical Package for the Social Science Versión 10.0 para Windows. Se realizó la comparación de proporciones de grupos independientes con el objetivo de determinar las variables de prevalencia más significativas y la prueba Ji cuadrado en su variante de independencia para verificar la relación entre las categorías seleccionadas. Las anomalías dentarias fueron las alteraciones más prevalentes. El sexo más afectado fue el masculino, así como el grupo de edades de 9-11 a os. Entre los factores etiológicos estudiados los hábitos fueron los más frecuentes seguido de los agentes físicos. Se concluye que existe una alta prevalencia de anomalías dentarias en estrecha relación con los hábitos deformantes.
