Sensualidad y Naturaleza. Mujer y Botánica en los paneles decorativos de Alfons Mucha

El presente trabajo analiza desde un punto de vista botánico los paneles decorativos, los cuales constituyen una de las mejores muestras de la estrecha relación mujer-vegetación en la obra de Alfons Mucha. Botánicamente hablando, mujer Mucha no es sinónimo de mujer flor. Y es que, el artista no sólo representa a sus féminas junto a estructuras reproductoras vegetales, sino que también las rodea de ramas, hojas, frutos e, incluso, de plantas enteras. Las representaciones vegetales que pueden encontrarse en los paneles tienen muchas veces una función simbólica y no meramente ornamental. Debido a que las flores conjugan erotismo y misticismo, no hay que descartar la posibilidad de que la representación de motivos florales en los paneles decorativos quizá tuviera como una de sus principales finalidades la de reforzar la ambigüedad de la mujer Mucha. Una mujer, voluptuosa a la par que espiritual, que se asocia ineludiblemente a la obra de este artista.This paper analyzes the decorative panels, which constitute one of the best examples of the close relationship woman-vegetation in the work of Alfons Mucha from a botanical point of view. Botanically speaking, Mucha’s women are not synonymous of flower women. And it is that, the artist not only represents its females with plant breeding structures, but also surrounds them with branches, leaves, fruits, and even entire plants. Botanical representations that can be found on the panels are often symbolic and not merely ornamental. Because the flowers combine eroticism and mysticism, the theory cannot be ruled out that perhaps one of the main purposes of the floral patterns was to reinforce the ambiguity of Mucha’s women. A woman, while voluptuous and spiritual, is inevitably associated with the work of this artist

La desigualdad de la riqueza en Tucumán entre 1869 y 1884. Una aproximación a su medición a partir de los inventarios post mortem

El objetivo del trabajo es estimar la distribución de la riqueza en Tucumán entre 1869 y 1884 haciendo uso de los inventarios post mortem disponibles en el Archivo Histórico de la Provincia de Tucumán (AHT). Se propone una metodología de expansión a la población que corrija los sesgos provenientes de trabajar con una muestra de este tipo. La estrategia empírica consiste en utilizar las distribuciones de las profesiones u ocupaciones por ubicación geográfi ca presentes en el Censo de 1869 para construir ponderadores que eliminen o al menos atenúen los sesgos presentes en la muestra. La caracterización obtenida servirá para revisar la imagen de Tucumán en este período como un espacio de bonanza económica, imagen documentada en notas de viajeros y estadistas

Temporal variation of the stress field during the construction of the central Andes: Constrains from the volcanic arc region (22–26°S), Western Cordillera, Chile, during the last 20 Ma

In order to understand the response of the stress field state to intrinsic processes during the construction of the Andes, such as thickening of the continental crust, lithospheric delamination, and/or thermal weakening, we investigate the stress field evolution of the arc region since the last 20 Myr, in the central Andes (22–26.5°S). The 43 reduced paleostress tensors derived from inversion of 682 fault slip data reveal a complex pattern of stress states during the last episode of orogenic construction and topographic uplift. We identify two geodynamic stages: the first stage corresponds to the construction of the Altiplano/Puna plateau and the second one to its gravitational collapse. Four stress states that have prevailed in the Altiplano/Puna plateau since middle Miocene times characterize the transition from one stage to the other. Along the study latitudes, a spatiotemporal change in stress state is clearly observed, which led to an understanding that a change in the stress field may be related not only to the boundary conditions but also to intrinsic factors associated with the construction of the Andean orogeny. Our results suggest that approximately at 13–10 Ma and approximately 8–5 Ma, in the southern Altiplano and northern Puna, and in the southern Puna, respectively, regional elevation and crustal thicknesses reached threshold values necessary to generate the orogenic collapse.Fil: Giambiagi, Laura Beatriz.

Subperiostial orbital abscess and apex syndrome as a complication after a mandibular molar extraction

Indexación: Web of Science; ScieloIntroducción: La diseminación de las infecciones que se extienden de dientes mandibulares y estructuras adyacentes hacia la órbita y tejido periorbitario son infrecuentes, pero graves ya que tienen el potencial de causar la pérdida de la visión. Objetivos: El propósito de este artículo es publicar un caso clínico muy interesante por lo infrecuente, y explicar a juicio de los autores las vías de diseminación de la infección, a su vez alertar a los diferentes especialistas involucrados sobre las severas consecuencias que pueden resultar tras la extracción de piezas dentales, como es la pérdida definitiva de la visión. Reporte del caso: Se trata de un paciente masculino de 43 años, sin antecedentes mórbidos relevantes, que fue enviado al Servicio Médico Legal para examen clínico forense con pérdida total de la visión del ojo derecho por atrofia óptica como complicación de un síndrome del vértice orbitario, luego de la exodoncia del tercer molar mandibular derecho. Conclusiones: Es fundamental el tratamiento oportuno y agresivo para detener la diseminación de una infección desde las estructuras adyacentes hacia la órbita. La comunicación efectiva interdisciplinaria entre los profesionales involucrados evita complicaciones de tipo médico-legales y secuelas definitivas al paciente.Introduction: Infection dissemination from mandibular teeth to the orbit and adjacent structures is infrequent, but nevertheless serious, as they may cause severe problems, including vision loss. Aim: The purpose of this study is to present a rare and interesting case of such a dissemination, to discuss the possible routes of infection propagation, and to alert the different specialists involved on the possible complications after dental extractions, such as visual loss. Report of the case: The case of a 43-year-old previously healthy male is presented. The patient was sent to the Medical Legal Service for clinical forensic examination after total vision loss of the right eye, caused by optic atrophy as a complication of orbital apex syndrome, after the extraction of the third right mandibular molar. Conclusions: Opportune and aggressive treatment is crucial to stop infection spread from adjacent structures to the orbit. Effective communication among the professionals involved avoids medical - legal complications and precludes permanent sequels to the patient.http://ref.scielo.org/yz5gt

Candidate gene linkage analysis indicates genetic heterogeneity in Marfan syndrome

Marfan syndrome (MFS) is an autosomal dominant disease of the connective tissue that affects the ocular, skeletal and cardiovascular systems, with a wide clinical variability. Although mutations in the FBN1 gene have been recognized as the cause of the disease, more recently other loci have been associated with MFS, indicating the genetic heterogeneity of this disease. We addressed the issue of genetic heterogeneity in MFS by performing linkage analysis of the FBN1 and TGFBR2 genes in 34 families (345 subjects) who met the clinical diagnostic criteria for the disease according to Ghent. Using a total of six microsatellite markers, we found that linkage with the FBN1 gene was observed or not excluded in 70.6% (24/34) of the families, and in 1 family the MFS phenotype segregated with the TGFBR2 gene. Moreover, in 4 families linkage with the FBN1 and TGFBR2 genes was excluded, and no mutations were identified in the coding region of TGFBR1, indicating the existence of other genes involved in MFS. Our results suggest that the genetic heterogeneity of MFS may be greater that previously reported.Universidade de São Paulo Hospital das Clínicas, Faculdade de Medicina Instituto de BiociênciaUniversidade de São Paulo Hospital das Clínicas, Faculdade de Medicina Laboratório de Otorrinolaringologia/LIM32Universidade Federal de São Paulo (UNIFESP) Departamento de Morfologia e Genética Centro de Genética MédicaUNIFESP, Depto. de Morfologia e Genética Centro de Genética MédicaSciEL

The 5Rs dilemma of radiotherapy for non-malignant diseases: 5Rs to darken or 5Rs to shine

Many benign diseases, so called because they are not a direct cause of death, nevertheless cause significant damage to the health of patients due to the associated pain, reduced functionality, increased disability and the negative impact they have on quality of life, which, together with the limited efficacy of many of the available treatments, make their management a challenge for every specialist. Radiotherapy, which has demonstrated its efficacy not only against cancer but also in many non-tumorous diseases, appears as a therapeutic option that deserves to be taken into account. However, there is still much resistance to considering the use of radiotherapy as a valid and acceptable alternative. The 5Rs to darken summarize the doubts and contradictions many specialists face to accept radiotherapy in non-neoplastic diseases. However, other 5Rs (to shine) can be argued to claim for the safety, reliability, and usefulness of radiation treatment for benign disease and as radiotherapy specialists we have to help the evidence shine and the darkness disappear
