Comentario a propósito de la presentación de la Dra. Elza Berquó. Reflexiones teórico metodológicas sobre la elaboración de cuestionarios de encuesta: una experiencia de integración de enfoques
Luppi, Irene;
Revista Brasileira de Epidemiologia , 2008, DOI: 10.1590/S1415-790X2008000500009
Abstract: se presenta una reflexión teórico metodológica sobre la elaboración de cuestionarios de encuesta recuperando dos cuestiones claves se?aladas por la dra. berquó, en su testimonio sobre las iniciativas desarrolladas en el campo de la salud reproductiva con el objetivo de producir datos que se puedan utilizar para formular políticas e implementar intervenciones en los distintos contextos: la complejidad y la flexibilidad. en particular, cuando se abordan cuestiones de mayor dificultad para su objetivación, tales como los pareceres, las valoraciones de los sujetos en relación con sus prácticas y las experiencias de padecimiento y cuidado. se enfatiza la necesidad de un riguroso examen de las categorías analíticas susceptibles de ser tratadas empíricamente y de la funcionalidad de los conceptos para la producción de indicadores de contenidos sistematizables para la comparación estadística. se presenta una experiencia de aplicación de un cuestionario, como instancia de integración metodológica en una investigación por encuesta, destinada a lograr una aproximación directa al universo de representaciones y valoraciones de la mujer, no mediada por los códigos y la lógica de quien las indaga. para su confección se recuperaron los hallazgos de una investigación antropológica preliminar y se armó un dispositivo de preguntas con expresiones textuales de las entrevistadas, a la manera de un esquema de apoyo del discurso de la mujer. la propuesta presentada, de relativa simplicidad, puede contribuir a superar dificultades vinculadas con la viabilidad de captación de determinadas temáticas según los contextos socioculturales, a nivel internacional.
"La nada del yo que soy": Desestabilizacionesde la autobiografía en la teoría literaria hacia fines de los '70
Luppi,Juan Pablo;
Enfoques , 2010,
Abstract: this paper proposes a reading of some passages from barthes' autobiographical scheme in roland barthes by roland barthes (1975), according to notions present in paul de man's essay "autobiography as defacement" (1979). by relying on the figures of rhetoric, one of them; and by reformulating lacan's categories, the other; both reflections constitute theories of reading, which discuss at least two variables often present in the interventions of the theoretical field: the category of genre and the notion of subject.
última novela del escritor en sus comienzos: La grande y el proyecto de Saer
Luppi,Juan Pablo;
Anclajes , 2010,
Abstract: supporting the illusion that is possible to start again, la grande (2005) redefines juan josé saer ′s project back to zero. favored by occasion of death while writing, although prior to that contingency, this last novel eludes ending and gets back to beginnings to go on narrating: it advances going back. la grande recovers and crosses one another two characters that had been suspended in the beginning (en la zona) and towards the end of the project (lugar), and effects subtle changes of function over recognized and established narrative pattern, mainly through a false intrigue ′s explosion, which covers space expanded to the universe and reaches represented subjectivities.
Los modelos de niveles múltiples: una estrategia analítica para el estudio de los problemas de salud de la población
Luppi, Irene;Boggio, Gabriela;
Revista Brasileira de Epidemiologia , 2006, DOI: 10.1590/S1415-790X2006000100007
Abstract: this paper presents the theoretical-methodological discussion about the applicability of multiple level models in the study of the health/sickness process, its determinants and conditioning factors, as a function of the stratification of society and the living conditions of its inhabitants. it goes back to the concept of population according to the theory of hierarchical complex systems, which seeks not to reduce reality, but rather to build the problem trying to identify different levels of abstraction in its approach. these models are options to overcome prior experiences, with the application of conventional statistical techniques, given that they make it possible to simultaneously analyze different levels of aggregation, while keeping its hierarchical structure. they consider the influence of the variables taking into account their belonging to lager units and the potential association existing between the units of a same level, that is, the intraclass correlation among variables relative to individuals, families and groups, close amongst themselves, which share similar conditions. in this manner, it tries to avoid oversizing the effect of macro level variables. the multiple level models are particularly appropriate to evaluate inequalities in the health/sickness/care process of the population groups and to analyze how social contexts affect the results and health risks of people. it highlights the need to develop information production strategies and analyses that make it possible to recognize levels of explanation and intervention to provide inputs and trigger actions suited to local specificities, at the level of micro-areas, so as to have more equity in healthcare.
última novela del escritor en sus comienzos: La grande y el proyecto de Saer Rethinking the Latest Writer's Novel: La grande and Saer's Project
Juan Pablo Luppi
Anclajes , 2010,
Abstract: Sosteniendo la ilusión de que es posible volver a empezar, La grande (2005) redefine el proyecto de Juan José Saer a partir de cero. Favorecida por la ocasión de morir escribiendo, aunque más acá de esa contingencia, esta última novela elude el final y vuelve a los comienzos para seguir narrando: avanza retrocediendo. La grande recupera y cruza a dos personajes suspendidos al inicio (En la zona) y hacia el final del proyecto (Lugar), y efectúa sutiles cambios de función sobre la forma narrativa reconocible y consagrada, privilegiadamente a través de una falsa explosión de la intriga, que cubre el lugar ampliado al universo y alcanza a las subjetividades representadas. Supporting the illusion that is possible to start again, La grande (2005) redefines Juan José Saer ′s project back to zero. Favored by occasion of death while writing, although prior to that contingency, this last novel eludes ending and gets back to beginnings to go on narrating: it advances going back. La grande recovers and crosses one another two characters that had been suspended in the beginning (En la zona) and towards the end of the project (Lugar), and effects subtle changes of function over recognized and established narrative pattern, mainly through a false intrigue ′s explosion, which covers space expanded to the universe and reaches represented subjectivities.

Natural Resources (NR) , 2013, DOI: 10.4236/nr.2013.43029
Abstract:

In this study, antimicrobial, antioxidant and cytotoxic activities of Spartium junceum L. aromatic water (SJAW), obtained by vacuum process distillation, were investigated. Antimicrobial activity of SJAW was evaluated against fungal organisms, Gram-positive and Gram-negative bacteria using agar-well diffusion method. Moreover, the ability of SJAW to sensitize Staphyloccus aureus to antibiotics was also evaluated. The antioxidant activity was examined by 2,2’-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity assay and the cytotoxic activity of SJAW main components was tested on melanoma RPMI 7932 and normal keratinocytes NCTC 2544 cell lines using the trypan blue method. The preparation did not show antibacterial activity against tested microorganisms and was unable, at tested concentrations/conditions, to sensitize Staphylococcus aureus to antibiotics clindamycin (2 μg) and tetracycline (30 μg). On the contrary SJAW possesses an appreciable antioxidant and cytotoxic activity suggesting its potential use for pharmaceutical applications.

Abstract: Skin manifestations are frequently observed in many internal malignancies. Cutaneous lesions, including benign neoplasms or pigmented lesions, can appear in the context of specific genodermatosis [1,2], lentiginosis [3], or paraneoplastic syndrome [4] representing a crucial cutaneous marker of internal malignancy in both the sporadic and genetic setting. Several familial cancer syndromes have additional malignant or non-malignant cutaneous features that form part of the clinical diagnostic criteria constituting a critical tool for clinical diagnosis.Several cutaneous paraneoplastic syndromes may be associated with underlying tumours. They include musculoskeletal disorders (clubbing, hypertrophic osteoarthropathy, dermatomyositis, and multicentric reticulohistiocytosis), reactive erythemas (erythema gyratum repens and necrolytic migratory erythema), vascular dermatoses (Trousseau's syndrome), papulosquamous disorders (acanthosis nigricans, tripe palms, palmar hyperkeratosis, acquired ichthyosis, pityriasis rotunda, Bazex's syndrome, florid cutaneous papillomatosis and extramammary Paget's disease), and disorders of hair growth (hypertrichosis lanuginosa acquisita) (Table 1) [4]. The clinical manifestations of these dermatoses may precede, coincide with, or follow the diagnosis of cancer. Most paraneoplastic dermatoses disappear when the primary tumour is removed and reappear in the case of recurrence or metastases of the cancer.The sign of Leser-Trélat is characterized by the eruptive appearance of multiple seborrheic keratoses (SK) in association with underlying malignant disease. Two European surgeons, Edmund Leser and Ulisse Trélat, were the first to describe the sign, and although they gave no mention of the presence of seborrheic keratoses reporting a specific association with angiomas - that probably does not exist - their names continue to be linked to a different paraneoplastic association [5]. In 1900, a subsequent report clearly defined the association of s

Abstract: introduction: malignant intraocular tumors are associated with an increase in the aqueous flare, caused by alterations of the blood-ocular barriers through various mechanisms. several studies have demonstrated an ocular flare increase using flare photometry in eyes with benign and malignant tumors. purpose: to evaluate flare photometry as an adjunct method in the differential diagnosis of choroidal malignant melanoma and choroidal nevus comparing to normal control eyes. methods: eyes with melanoma and nevus were diagnosed by indirect binocular ophthalmoscopy and/or ultrasound were evaluated. the fellow normal eyes were used as a control. in all subject and control eyes flare photometry was performed using the laser flare meter (fc 500, kowa), under mydriasis. statistical analysis was done using the wilcoxon, mann-whitney, and spearman tests. results: thirty-one eyes with malignant melanoma and 18 eyes with nevus were evaluated. the flare photometry average in the eyes with malignant melanoma was 17.1 ph/ms and in the control fellow eyes it was 4.06 ph/ms. in eyes with choroidal nevus the flare photometry average was 6.12 ph/ms and in the control fellow eyes it was 4.47 ph/ms. the flare photometry was higher in eyes with malignant melanoma and nevus than in the fellow normal eyes (p<0.001 and p<0.01). comparing the eyes with malignant melanoma and nevus, flare photometry was significantly higher in eyes with malignant melanoma (p<0.001). there was a positive correlation between the tumor thickness and flare photometry (r=0.47). conclusion: flare photometry is a helpful tool in the differential diagnosis of malignant melanoma and choroidal nevus.
