Harris D,Paul; Serrano H,Carolina; Venegas E,Alejandro;

Abstract: helicobacter pylori causes gastrointestinal disease including peptic ulcer and gastric cancer. an h. pylori vaccine is relevant because of the high prevalence of the infection and its associated complications. extensive use of traditional antimicrobial therapies to eradicate h. pylori is not feasable, specially in developing countries, in part because of their high cost, associated adverse effects, the risk of reinfection, and the emergence of antimicrobial drug resistance. numerous animal studies have been performed to determine infection outcomes and to explore the feasibility of a vaccine eradication or prevention of infection. these animal models with the possible exception of monkeys, have not been sufficient to address fundamental issues due to controversial results. a human model of h. pylori infection needs to be developed aimed to select an optimum vaccine candidate. the ultimate scientific goal will be to develop field studies using advanced vaccine candidates, but the current state of knowledge does is insufficient and has provided such candidates. these studies need to be designed in order to provide relevant information on immunity and pathogenesis associated to h. pylori
Vacunas en desarrollo: Helicobacter pylori Vaccines under development: Helicobacter pylori

Revista chilena de infectología , 2006,
Abstract: La infección con Helicobacter pylori es la causa de patologías gastrointestinales como úlcera péptica y cáncer gástrico. Una vacuna contra H. pylori es relevante debido a la alta prevalencia de la infección y a la morbi-mortalidad asociada a ésta en nuestro país. El uso masivo de terapias antimicrobianas actuales no es una estrategia factible, especialmente en países en desarrollo, en parte debido al alto costo, los múltiples efectos adversos, el riesgo de reinfección y la emergencia de resistencia a los antimicrobianos. Numerosos modelos animales han sido utilizados durante a os para determinar el curso de la infección por H. pylori y explorar la factibilidad de una vacuna, ya sea para erradicar o prevenir la infección. Dichos modelos, con la posible excepción de los monos, no son suficientes para responder preguntas fundamentales debido a resultados contradictorios. Un modelo humano de infección por H. pylori debe ser desarrollado con el principal propósito de seleccionar vacunas óptimas. El objetivo final es el desarrollo de estudios de campos de vacunas candidatas, pero el estado actual del conocimiento no proporciona una metódica adecuada para seleccionar tales vacunas candidatas promisorias. Dichos estudios pueden ser dise ados para proporcionar información relevante sobre la inmunidad y patogénesis de la infección por H. pylori Helicobacter pylori causes gastrointestinal disease including peptic ulcer and gastric cancer.

Códigos visuales de género y configuraciones sexuales evidenciadas en la fotografía
Serrano,Héctor; Zarza,Martha Patricia; Carolina,Serrano; Gómez,Beatriz; Iduarte,Joaquín;
Revista Latinoamericana de Ciencias Sociales, Ni?ez y Juventud , 2011,
Abstract: from the first years of life, each human being receives an accumulation of attitudes, conducts and values that are learned and apprehended sometimes like specific learning ideals and some others like imitation models of adult's behavior. this context has been structured historically from the binary system of masculinity/femininity, whose cultural reduction determines gender inequalities that affect social interactions. the gender inequalities are identified in the domestic and the massive circulation of images that contribute with the configuration of codes and representations that promote confusing gender identities. the aim of this article is to show some visual codes presented in a group of photographs that exhibit the perpetuation of gender inequalities.

Eros, Thánatos y Psique: una complicidad triádica
Carolina Serrano Barquín,Francisco Salmerón Sánchez,Héctor Serrano Barquín
Ciencia Ergo Sum , 2010,
Abstract: Se parte de personajes mitológicos para analizar la relación triádica entre erotismo/ creación, sufrimiento/pulsión de muerte y psicoanálisis, disertación que hacen los autores desde sus diversas prácticas docentes y de investigación. Para ello se retoma la idea de que la creatividad no es coto de poder de algún campo disciplinar específico, que se puede abordar como proceso epistémico, comunicativo, artístico, sensoperceptual, inconsciente. Entrar al mundo de la creación es entrar al mundo de las posibilidades, para imaginar y recrear universos excluidos.

Utilidad del diagnóstico serológico de la infección por Helicobacter pylori en ni?os

Abstract: helicobacter pylori (h. pylori) colonizes 50% of the world′s population. the infection is acquired during infancy; an age group of non-invasive diagnostic methods need to be urgently validated. our aim was to review the literature and evaluate the usefulness of serological diagnosis with special emphasis on the paediatric population. the relevance of these methods has been focused in epidemiological studies. in adult populations, the determination of antibodies against h. pylori exhibits a sensitivity and specificity of over 90%, being comparable to other invasive endoscopy based methods. in the paediatric population, the performance of serological testing has been less successful, with lower sensitivity and specificity. this underlies the need to establish more precise cut off values, based on local populations, where studies using antibodies as diagnostic markers of h. pylori are planned
Helicobacter pylori: una causa no tradicional de deficiencia de hierro y anemia

Abstract: helicobacter pylori (h. pylori) is the most common cause for chronic gastritis, duodenal ulcers, malt lymphoma and gastric cancer. h.pylori has also been associated with several extra gastric diseases such as iron deficiency (id) and iron deficiency anemia (ida). several mechanisms by which h.pylori might contribute to the development of id/ida have been proposed. alterations in the physiology of gastric mucosa and of iron metabolism as a consequence of the infection as well as direct competition for iron by h. pylori have been proposed as possible causes for id/ida development. h. pylori causes alterations in gastric ph as well as in the concentration of ascorbic acid in the stomach limiting the absorption of dietary iron in the gastrointestinal tract. in addition, pro-inflammatory cytokine secretion in response to the infection, in particular il-1p are able to modulate acid secretion and stimulate the secretion of hepcidin from the liver inhibiting liberation of iron from iron stores. these results in less iron available for eritropoyesis, thus contributing to id/ida development. several studies have suggested a direct relationship between the presence of the infection and the development of id/ida in children, adolescents and adults. h. pylori eradication has been associated to a better response to oral iron therapy in ida patients. however some controversy still remains regarding the role of the infection in id/ida and the mechanisms involved. studies aimed to evaluate the relationship between h. pylori and acid output in gastric mucosa, as well as studies to determine iron capture in strains isolated from ida patients are still being conducted in order the shed some definitive light in the relationship between this bacterium and id/ida and their contributing mechanisms.

Abstract: background: during infancy, preventive, diagnostic and therapeutic efforts for helicobacter pylori infection should be made. aim: to evaluate non-invasive diagnostic methods such as stool antigen test (hpsa) and serum anti-h pylori antibody detection (igg e iga), compared to endoscopy-based invasive methods (histology and urease test) for the diagnosis of helicobacter pylori infection. patients and methods: thirty nine children (aged 3 to 14 years, 20 males) referred for upper gastrointestinal endoscopy, were studied. the gold standard to diagnose helicobacter pylori infection was defined as a positive invasive diagnostic test (histology and/or urease test). sensitivity (s), specificity (e) and positive (ppv) and negative (npv) predictive values were obtained for hpsa and serum antibodies. results: ten children (26%) were infected with h pylori. s, e, ppv and npv for hpsa were 90, 100, 100 and 97%, respectively. the figures for serum igg were 81, 97, 89 and 93%, respectively and for iga, 90, 76, 36 and 96%, respectively. conclusions: hpsa was sensitive and specific as a clinical and epidemiological tool to evaluate h pylori infection in children. serology was not as accurate, but igg had a better performance than iga
