Prensa escrita mendocina y construcción identitaria sobre los pueblos originarios de Argentina

En el siguiente trabajo presentamos un estudio multidimensional sobre la conceptualización de los pueblos originarios que han constituido los medios de prensa escrita en Mendoza durante la primera década del siglo XX. Para llevarlo a cabo acudimos al Archivo de Hemeroteca de la Biblioteca General San Martín de la Ciudad de Mendoza, teniendo como referencia al Diario Los Andes, principal periódico de la provincia, creado en 1882 y vigente en la actualidad. El objetivo del estudio es la identificación de las distintas formas de construcción conceptual sobre los pueblos etnográficos del actual territorio argentino que difundió dicho diario, y del modo en que dichos artículos periodísticos jugaron un rol activo en relación con el proceso de construcción de alteridad sociocultural y la legitimación de las políticas etnocidas implementadas por las clases dominantes.

Estudio sobre la viabilidad de la implementación del jurado de conciencia en el ordenamiento colombiano

El objeto del presente trabajo final de grado es analizar la viabilidad de la implementación de la figura del jurado de conciencia en el sistema penal colombiano, que fue suprimida mediante el Decreto 1861 de 1989. A su vez, hacer un análisis de derecho comparado con el fin de determinar los aspectos positivos y negativos de la implementación de los jurados en otros sistemas jurídicos. El resultado del análisis propuesto pretende determinar si es procedente la implementación de los jurados de conciencia en Colombia.

Estresse em pacientes com glaucoma primário de ângulo aberto

Glaucoma Primário de Ângulo Aberto (GPAA) é uma importante causa de cegueira no mundo. O presente trabalho teve como objetivo investigar: (1) presença e tipo de estresse; (2) relação do número de colírios e estresse; (3) percepção do glaucoma e tratamento. Um estudo transversal e quantitativo foi realizado com 102 pacientes do Ambulatório de Oftalmologia do HC-FMUSP, com roteiro temático e Inventário de Sintomas de Estresse de Lipp. A maioria dos pacientes apresentou estresse (65,7%) e não houve correlação entre estresse e número de colírios. "Tempo de tratamento", "dificuldades na vida diária" e "dificuldades em pingar o colírio" foram variáveis independentemente associadas ao estresse. Conclui-se que o estresse pode interferir negativamente no enfrentamento da doença em pacientes com GPAA.

Evaluation of capillaries with different inner coatings for DNA analysis using dilute polymer solutions by capillary electrophoresis

In this work three capillary columns, one with uncoated inner wall and two with covalently-bound internal coatings - poly(vinyl alcohol) (PVA) and poly(dimethylacrylamide) (PDMA) - both covalently covered - were used to separate DNA fragments and compared to DNA separation using replaceable polymer solutions. The separations were performed using hydroxyethylcellulose (HEC) (90-105 kDa) in concentrations ranging from 0.00 to 2.00% m/v. The results indicated that the separation efficiency was higher in the PVA capillary than in the PDMA in all evaluated concentrations of HEC. In addition, higher resolution was also observed in PVA-coated capillary since in PDMA the shape of the peaks was not reproducible when subsequent runs were performed. Contrary to what has previously been reported in the literature, no reasonable separation was possible in bare fused silica.

Cytogenetic analysis of Astylus antis (Perty, 1830) (Coleoptera, Melyridae): Karyotype, heterochromatin and location of ribosomal genes

Cytogenetic analysis of Astylus antis using mitotic and meiotic cells was performed to characterize the haploid and diploid numbers, sex determination system, chromosome morphology, constitutive heterochromatin distribution pattern and chromosomes carrying nucleolus organizer regions (NORs). Analysis of spermatogonial metaphase cells revealed the diploid number 2n = 18, with mostly metacentric chromosomes. Metaphase I cells exhibited 2n = 8II+Xyp and a parachute configuration of the sex chromosomes. Spermatogonial metaphase cells submitted to C-banding showed the presence of small dots of constitutive heterochromatin in the centromeric regions of nearly all the autosomes and on the short arm of the X chromosome (Xp), as well as an additional band on one of the arms of pair 1. Mitotic cells submitted to double staining with base-specific fluorochromes (DAPI-CMA3) revealed no regions rich in A+T or G+C sequences. Analysis of spermatogonial mitotic cells after sequential Giemsa/AgNO3 staining did not reveal any specific mark on the chromosomes. Meiotic metaphase I cells stained with silver nitrate revealed a strong impregnation associated to the sex chromosomes, and in situ hybridization with an 18S rDNA probe showed ribosomal cistrons in an autosomal bivalent.

Interfacial evaluation of experimentally weakened roots restored with adhesive materials and fibre posts: An SEM analysis

Objectives: To evaluate the bonding interface in experimentally weakened roots reinforced with adhesive restorative materials and quartz fibre posts, varying the light-exposure time of the composite resin used for root reinforcement. Methods: Twelve extracted human maxillary incisors teeth were used. The crowns were removed and the roots were endodontically treated. After post space preparation, the roots were assigned to four groups. The thickness of the root dentine was reduced and adhesively restored with composite resin light-activated through a translucent fibre post for either 40 s (group 1), 80 s (group 2) or 120 s (group 3). In the case of control (group 4), the roots were not weakened. One day after post cementation, the specimens were sectioned transversally in three slices and processed for scanning electron microscopic analysis to observe bonding interface formation, quality of the hybrid layer and density of resin tags using a four-step scale method. Results: Formation of a hybrid layer and resin tags were evident in all groups. There was no statistically (p > 0.05) significant difference between the regions analysed in each group (Friedman test) and between groups in each section depth (Kruskal-Wallis test). Furthermore, comparison of the flared/reinforced groups showed that the different time;; used for composite resin cure did not affect the results significantly (Kruskal-Wallis test, p = 0.2139). Conclusions: Different light-exposure times used for composite resin polymerisation during root canal reinforcement did not affect significantly the formation and quality of the dentine/adhesive/composite resin bonding interface.

The role of dentists in-diagnosing osteogenesis imperfecta in patients with dentinogenesis imperfecta

Background. Osteogenesis imperfecta (OI), also known as ""brittle bone disease,"" can be difficult to diagnose in its mild form. The authors describe a clinical case of a diagnosis of dentinogenesis imperfecta (DI), In which a literature review combined with an analysis of dental alterations led to indications of OI involvement. Case Description. Since DI can be associated with OI, the authors reviewed correlated studies and obtained a new medical history from the patient. They then conducted a radiographic and clinical examination of the dentition and submitted an affected third molar to scanning electron microscopy analysis. They compared their findings with descriptions of OI type I dental alterations in the literature and confirmed their diagnosis by means of a medical evaluation. Clinical Implications. In cases in which DI is diagnosed, patients should be examined carefully and the occurrence of OI should be considered `since, in its mild form, it might be misdiagnosed.

Los saqueos y las ollas populares de 1989 en el Gran Buenos Aires. Pasado y presente de una experiencia formativa

En la década del 1980, un nuevo fenómeno: las tomas de tierras o "asentamientos" transforma los procesos de urbanización en el Area Metropolitana de Buenos Aires. Los autores, miembros de un equipo de investigación de la Universidad de General Sarmiento (Argentina), entrevistaron a habitantes de estos asentamientos, y se sorprendieron con las frecuentes menciones a los saqueos y ollas populares ocurridos doce años atrás en un contexto de hiperinflación. En este artículo, estos hechos son considerados como constitutivos de una experiencia formativa iniciada con la organización para la toma de tierras y seguida poco después por los saqueos de supermercados y otros negocios durante la hiperinflación de 1989. Esto da origen, posteriormente, a las ollas populares que paliaron el hambre de ese momento, y que luego se transformaron en comedores comunitarios, guarderías y otras organizaciones que hoy persisten. Esta indagación se apoya en los relatos de los entrevistados y en la recopilación de diferentes periódicos de ese momento.

Candidemia in a Brazilian tertiary care hospital: species distribution and antifungal susceptibility patterns

Recent studies have shown differences in the epidemiology of invasive infections caused by Candida species worldwide. In the period comprising August 2002 to August 2003, we performed a study in Santa Casa Complexo Hospitalar, Brazil, to determine Candida species distribution associated with candidemia and their antifungal susceptibility profiles to amphotericin B, fluconazole and itraconazole. Antifungal susceptibility was tested according to the broth microdilution method described in the NCCLS (M27A-2 method). Only one sample from each patient was analyzed (the first isolate). Most of the episodes had been caused by species other than C. albicans (51.6%), including C. parapsilosis (25.8%), C. tropicalis (13.3%), C. glabrata (3.3%), C. krusei (1.7%), and others (7.5%). Dose-dependent susceptibility to itraconazole was observed in 14.2% of strains, and dose-dependent susceptibility to fluconazole was found in 1.6%. Antifungal resistance was not found, probably related to low use of fluconazole. Further epidemiological surveillance is needed.

BRAIN ABSCESS DUE TO Staphylococcus aureus OF CRYPTOGENIC SOURCE IN AN HIV-1 INFECTED PATIENT IN USE OF ANTIRETROVIRAL THERAPY

The spectrum of neurological complications associated with human immunodeficiency virus type 1 (HIV-1) infection is broad. The most frequent etiologies include primary diseases (caused by HIV itself) or secondary diseases (opportunistic infections or neoplasms). Despite these conditions, HIV-infected patients are susceptible to other infections observed in patients without HIV infection. Here we report a rare case of a brain abscess caused by Staphylococcus aureus in an HIV-infected patient. After drainage of the abscess and treatment with oxacilin, the patient had a favorable outcome. This case reinforces the importance of a timely neurosurgical procedure that supported adequate management of an unusual cause of expansive brain lesions in HIV-1 infected patients.

Intrahospital spread of carbapenem-resistant Pseudomonas aeruginosa in a University Hospital in Florianópolis, Santa Catarina, Brazil

INTRODUCTION: Carbapenem-resistant Pseudomonas aeruginosa (CRPA) has been isolated with increasing frequency in Brazilian hospitals. Since June 2003, its detection in a teaching hospital in the city of Florianópolis, Brazil, has increased. This study aimed to investigate the minimal inhibitory concentration (MIC), presence of Metallo-β-lactamase (MβL) and a possible clonal relationship among the isolates. METHODS: The study included 29 CRPA and seven isolates with reduced susceptibility. The MIC was determined by agar-dilution. Detection of MβL was performed by Double Disk Sinergism (DDS) and Combined Disk (CD). The MβL gene was verified by PCR and nucleotide sequence analysis. Epidemiological typing was performed by pulsed-field gel electrophoresis. RESULTS: Among the 29 carbapenem-resistant isolates, polymyxin B presented 100% susceptibility and piperacillin/tazobactam 96.7%. Seventeen (62%) strains were verified as clonal (A clone) and among these, six isolates indicated phenotypically positive tests for MβL and harbored the blaSPM-1 gene. The first CRPA isolates were unrelated to clone A, harbored blaIMP-16 and were phenotypically positive only by CD. CONCLUSIONS: The spread of a high-level of resistance clone suggests cross transmission as an important dissemination mechanism and has contributed to the increased rate of resistance to carbapenems. This study emphasizes the need for continuous surveillance and improved strategies.
