El espa?ol neutro en los discursos de especialidad: ¿mito, utopía o realidad?
García Izquierdo,Isabel;
íkala, Revista de Lenguaje y Cultura , 2009,
Abstract: this paper refects on the possibility of achieving a neutral (international) spanish, based on an analysis of some determining factors in the current confguration of the spanish language. the limitations and drawbacks of a neutral spanish notwithstanding, we defend its appropriateness, particularly in the feld of scientifc spanish, as a tool to homogenize certain usages. this could enhance language cohesion in some contexts and, as a result, help spanish to be viewed as a language of prestige. we also propose a conceptualization of neutral spanish. we conclude by stating that neutral spanish is not yet a reality but could become one if the different authorities involved in the standardization of specialized discourse were to agree on some basic criteria.

Izquierdo Peraile, Isabel
Gladius , 1999, DOI: 10.3989/gladius.1999.15
Abstract: In this paper we publish an Ibenan set of weapons -swords, lances and dagger essentially-, coming from the cemetery of the settlement so-called Mas de Barberán (Nogueruelas, Teruel). An anthropomorphic stele with an inscription recently studied is associated to the same site. This stele represents an armed with disk-cuirass masculine personage. En este trabajo presentamos un lote inédito de armamento ibérico espadas, lanzas y pu al esencialmente procedente de la necrópolis correspondiente al poblado del Mas de Barberán (Nogueruelas, Teruel). Al mismo yacimiento se asocia la estela antropomorfa con inscripción que representa un personaje masculino armado con disco-coraza, recientemente estudiada.
ética y quehacer científico. de la estrategia identitaria a la estrategia política
Teresa Yurén Camarena,Isabel Izquierdo
Perfiles educativos , 2000,
Abstract: El presente es un análisis e interpretación del discurso en torno a las relaciones entre ética y quehacer del científico; se explicitan las significaciones de la ética profesional en relación con la identidad profesional y la formación de científicos, sus estrategias de diseminación en el ámbito institucional y sus efectos de poder. El eje del discurso de la ética es la honestidad, pero está recubierto y mediatizado por el discurso epistémico. La competitividad y el borramiento del sujeto son estrategias identitarias en la constitución del carácter científico; cobijadas en el prestigio del trabajo, constituyen parte de una estrategia política. El discurso contribuye a conformar una eticidad cuyo referente es la cientificidad, pero no es equitativa y se vuelve contra ésta.
Investigating specialized translators: Corpus and documentary sources
Isabel García-Izquierdo,Tomás Conde
Ibérica , 2012,
Abstract: This paper describes research carried out through electronic surveys of three groups of translators working in different areas of expertise (legal, medical and technical) that aimed to discover their socio-professional profile, their opinions both on corpora and other documentary sources, and the use they make of them. Certain characteristic features emerged from the analysis of data on the three population groups, regarding years of experience, documentary sources used and most usual clients. For example, even if legal translators seem more satisfied with the documentary sources available, medical translators never use translation memories, and technical translators often refer to thesauri. In any event, regardless of their area of activity, most subjects feel the need for a specialized corpus combining formal, terminological-lexical, macrostructural and conceptual aspects, as well as contextual information. That is the reason why the GENTT 3.0 Corpus is believed to meet the expectations and needs of professional translators.
Portadores de Neisseria meningitidis y Neisseria lactamica en tres grupos de edades diferentes.
Niury Nú?ez,Isabel Martínez,Luis Izquierdo,Niurka álvarez
Vaccimonitor , 2007,
Abstract: Se determinó la prevalencia de N. meningitidis y N. lactamica, así como su relación con las variables edad y sexo enindividuos de tres grupos de riesgo diferentes (círculo infantil, escuela primaria y escuela universitaria), a los que se lesrealizó exudado de la nasofaringe posterior. Se identificaron los marcadores epidemiológicos de las cepas deN. meningitidis aisladas y se analizó la presencia de otros microorganismos de la familia Neisseriaceae. Laidentificación de las cepas obtenidas se realizó por el sistema APINH (bioMérieux), el seroagrupamiento deN. meningitidis se determinó por aglutinación en lámina portaobjetos con antisueros específicos y los sero/subtipos einmunotipos se identificaron por un ensayo inmunoenzimático de células enteras con anticuerpos monoclonales. El 10,9% de los sujetos investigados fue portador de N. meningitidis, cifra que aumentó con la edad. La prevalencia de portadores tuvo el siguiente comportamiento: Grupo 1: ni os de 0-6 a os (4,3%); Grupo 2: ni os de 5-12 a os (6,9%) y Grupo 3: adultos jóvenes de 17-22 a os (25,1%). No hubo diferencias significativas respecto al sexo (p > 0,05). En elGrupo 1 predominó el fenotipo NA:NT:P1.6:L3,7,9 (71,5%), mientras que, en los Grupos 2 y 3, prevaleció la asociación NA:NT:P1.NST:L3,7,9 (36,4 y 25%, respectivamente). El predominio de cepas no epidemiogénicas avalan el impacto de la inmunización en Cuba con VA-MENGOC-BC . El aislamiento de cepas de N. lactamica disminuyó a medida que aumentó la edad: Grupo 1 (47,5%), Grupo 2 (29,8%) y Grupo 3 (3%).
Caracterización fenotípica de cepas invasivas de Neisseria meningitidis aisladas en Cuba durante 20 a os
Isabel Martínez,Gustavo Sierra,Niury Nú?ez,Luis Izquierdo
Vaccimonitor , 2006,
Abstract: Se investigaron los marcadores epidemiológicos (serogrupos, serotipos, subtipos, inmunotipos) de 429 cepas invasivas, aisladas enCuba durante 20 a os (1982-2002). Basándonos en el comportamiento de la incidencia de la Enfermedad Meningocócica (EM) en el período investigado, las cepas se distribuyeron en dos etapas: epidémica y postepidémica. La epidémica, comprendió 279 cepas aisladas entre 1982-1992 y la postepidémica, incluyó 150 aislamientos pertenecientes al período comprendido entre 1993-2002. Todas se cultivaron en Agar Mueller Hinton con suero fetal bovino (5%) y se incubaron 24-48 horas, 37 0C, en atmósfera húmeda con 5% de C02. La identificación de género, especie y serogrupo, se realizó mediante métodos convencionales; para la caracterización de los sero/subtipos e inmunotipos, se utilizó el ensayo inmunoenzimático (ELISA) de células enteras con anticuerpos monoclonales. En ambas etapas predominó el serogrupo B (97,90%): epidémica (96,77%) y postepidémica (100%). Sin embargo, el serogrupo C (1,43%)y cepas no agrupables (1,8%), sólo se observaron en aislamientos de la etapa epidémica. Los otros marcadores prevalentes fueron:serotipo 4 (86,48%), subtipo P1.19,15 (78,32%), inmunotipo L3,7,9 (90,2% ), todos mostraron cifras similares en ambos períodos.Predominó el fenotipo B:4:P1.19,15:L3,7,9 (69,69%), aunque, en la etapa postepidémica (77,34%), el porcentaje fue superior al de la etapa epidémica (65,66%) (p<0,05); además, en las cepas de este período, se observó una mayor diversidad de asociaciones fenotípicas.Los resultados obtenidos de esta caracterización fenotípica de las cepas de Neisseria meningitidis aisladas de enfermos aporta datos valiosos al estudio, prevención y control exitoso de la EM en Cuba.
Fatal Strongyloides Hyperinfection Complicating a Gram-Negative Sepsis after Allogeneic Stem Cell Transplantation: A Case Report and Review of the Literature
Isabel Izquierdo,Javier Briones,Rafael Lluch,Cristina Arqueros,Rodrigo Martino
Case Reports in Hematology , 2013, DOI: 10.1155/2013/860976
Abstract: Strongyloides stercoralis is an intestinal nematode that causes strongyloidiasis, which affects 30 to 100 million people worldwide. Risk factors for hyperinfection and disseminated disease include immunosuppressive drug therapy, human T-lymphotropic virus-1 (HTLV-1) infection, solid organ and bone marrow transplantation, hematologic malignant diseases, hypogammaglobulinemia, and severe malnutrition and associated conditions. The diagnosis can be difficult because a single stool examination fails to detect larvae in up to 70% of the cases, and the symptoms are nonspecific. Although eosinophilia is a common finding in patients with chronic Strongyloides infection, it is an unreliable predictor of hyperinfection. Furthermore, the lack of eosinophilia while receiving immunosuppressive therapy cannot reliably exclude the underlying chronic Strongyloides infection. We report here a fatal Strongyloides hyperinfection in a patient receiving allogeneic stem cell transplantation; risk factors and outcome in this clinical setting are discussed. 1. Introduction Strongyloides stercoralis and Strongyloides fuelleborni are two intestinal nematodes that cause strongyloidiasis, which affects an estimate of 30 to 100 million people worldwide. The most common and globally distributed human pathogen of clinical importance is S. stercoralis. A deregulation of the host’s immune response during this latent infection may be lethal because multiple infective larvae can develop and invade other organs in addition to the intestine, causing sepsis and even death (hyperinfection syndrome) [1]. The clinical manifestations of S. stercoralis hyperinfection vary widely. Healthy individuals are usually asymptomatic even if chronically infected. The immunocompromised host is at risk for disseminated Strongyloides infection after transplant [2]. The diagnosis of strongyloidiasis should be suspected if there are clinical signs and symptoms (maculopapular rash, dyspnea, gastrointestinal symptom, etc.) or peripheral blood eosinophilia [3, 4]. A careful history including demographic data (residence in) or travelling to endemic areas should be assessed before transplantation [3]. Eosinophilia is usually the only indication of the presence of S. stercoralis infection [4]. However, although eosinophilia is a common finding in patients with chronic Strongyloides infection, it is an unreliable predictor of hyperinfection. Moreover, in chronic strongyloidiasis, eosinophilia may be present only intermittently [3–6], and, in fact, lack of eosinophilia while receiving immunosuppressant therapy cannot
Placing Place: Speech in José María Arguedas’ The Foxes  [PDF]
Lucas Izquierdo
Advances in Literary Study (ALS) , 2013, DOI: 10.4236/als.2013.14011
Abstract:

Critical approximations carried out from the global south entail spatial and epistemological challenges to the hegemony of western modernity. This article argues that José María Arguedas’ The Fox from Up Above and the Fox from Down Below(1971) produces a language that embodies and transforms an Aris-totelian conception of speech. Written in an avant-garde vernacular, the novelcongeals a multiplicity of worldviews, utopias, and mercantile discourses that converge in Chimbote-Peru. Guided by Jacques Ran-ciere’s Disagreement(1998) and Dissensus(2010), the analysis is divided in two stages. The first stage examines the notion of speech and a constitutive wrong that establishes a community. The second stage addresses the symbiotic relationship of speech, its place of enunciation, and the conception of an alternate social order. The analysis places Arguedas incritical dialogue with Aristotelian speech, Ranciere’s notion of wrong, and the emergence or failure of claiming speech in canonical history.

Nanostructured Mesoporous Silicas for Bone Tissue Regeneration
Isabel Izquierdo-Barba,Montserrat Colilla,María Vallet-Regí
Journal of Nanomaterials , 2008, DOI: 10.1155/2008/106970
Abstract: The research on the development of new biomaterials that promote bone tissue regeneration is receiving great interest by the biomedical scientific community. Recent advances in nanotechnology have allowed the design of materials with nanostructure similar to that of natural bone. These materials can promote new bone formation by inducing the formation of nanocrystalline apatites analogous to the mineral phase of natural bone onto their surfaces, i.e. they are bioactive. They also stimulate osteoblast proliferation and differentiation and, therefore, accelerate the healing processes. Silica-based ordered mesoporous materials are excellent candidates to be used as third generation bioceramics that enable the adsorption and local control release of biological active agents that promote bone regeneration. This local delivery capability together with the bioactive behavior of mesoporous silicas opens up promising expectations in the bioclinical field. In this review, the last advances in nanochemistry aimed at designing and tailoring the chemical and textural properties of mesoporous silicas for biomedical applications are described. The recent developed strategies to synthesize bioactive glasses with ordered mesopore arrangements are also summarized. Finally, a deep discussion about the influence of the textural parameters and organic modification of mesoporous silicas on molecules adsorption and controlled release is performed.
