Andrés Pérez: una vida para el teatro

Si pienso en el teatro, más allá de una definición académica del término, pienso en una fiesta y un evento popular con participación “masiva”, pienso en un ritual, en un espacio sagrado y todo eso está presente en el trabajo de Andrés Pérez. Esta es mi verdad, la que voy a contar en este escrito, una verdad subjetiva sin duda y además una verdad que pasa no solo a través de lo efímero del teatro, sino también pasa por los recuerdos de mis testigos, por su memoria, gracias a las entrevistas que he realizado, a las notas de prensa y a los libros que he leído, la figura de Andrés Pérez ha tomado cuerpo y voz, por ejemplo con los videos que he logrado encontrar donde se hace presente. Otro elemento para mí interesante de la figura de Andrés es la popularidad que tiene en Chile y en Suramérica. Es muy conocido por haber trabajado casi siempre con personajes e historias marginales y por no haberse olvidado nunca de donde venía, llevando así el teatro a lugares pobres, por eso la gente lo ama: es una figura viva en la memoria de la sociedad chilena. La figura de Andrés Pérez, quedó grabada en el imaginario colectivo y se ha convertido en un héroe post dictadura y en plena época de reconciliación ha llegado al éxito. Fue el creador de un teatro masivo y popular, uniendo elementos del circo, magia, mimo, danza, teatro, música…

Venezuelan economic laboratory. The Case of the altruistic economy of Felipe Pérez Martí

Felipe Pérez Martí, who was the Venezuelan Minister of Planning and Development in the government of Hugo Chávez, proposes an economic model that he calls the altruistic economy or fourth way, which leads cooperative game theory to its logical extremes postulating a pure communism. Here we sustain that, first, it is impossible in the model of Pérez Martí to marginally allocate non-primary goods to those most in need or who most value them, facing a problem of defective economic calculation, and second, in order to achieve equality, he would have to replace his atomic local planners by a central planner, who would be unable to overcome the problem of imperfect and and incomplete information.

La inscripción registral de las fundaciones canónicas

La llibertat religiosa ha experimentat un desenvolupament important en l’Estat Espanyol des de la Constitució de 1978, donant lloc a un marc jurídic que avui en dia es segueix desenvolupant. Un instrument important per potenciar ’aquesta llibertat religiosa és el Registre d’entitats religioses en el que s’inscriuen totes les entitats que desenvolupen el seu culte a Espanya, i en especial les fundacions religioses de l’Esglèsia Catòlica.

La busca de Jorge Luis Borges: metáfora, metafísica y misticismo

El presente trabajo se propone analizar el influjo de la cultura islámica y, muy especialmente, de su vertiente mística, en tres relatos de la ‘serie árabe’ de Jorge Luis Borges: El Zahir, La busca de Averroes y El acercamiento a Almotásim, analizados en torno a los conceptos básicos de metáfora, metafísica y misticismo, respectivamente. El objeto de este estudio es clarificar las fuentes empleadas en dichos textos para desentrañar las actitudes ideológicas de raigambre árabe que comprenden y la particular interpretación que el autor hace de éstas, dando así una idea más completa y global de la poética borgesiana

Use of an immunodominant p17 antigenic fraction of Neospora caninum in detection of antibody response in cattle

A Neospora caninum 17 kDa protein fraction (p17) has been described as an immunodominant antigen (IDA) under reducing and non-reducing conditions. The aim of the present study was to investigate the diagnostic utility of p17 in cattle. In order to achieve this, p17 was purified by electroelution from whole N. caninum tachyzoite soluble extract and a p17-based Western blot (WB-p17) was developed. The p17 recognition was measured by densitometry and expressed as OD values to check the validity of the WB-p17. A total of 131 sera including sequential samples from naturally- and experimentally-infected calves and breeding cattle were analysed by WB-p17 and compared with IFAT using whole formalin-fixed tachyzoites as a reference test. The results obtained highlight the feasibility of using the N. caninum p17 in a diagnostic test in cattle. Firstly, the assay based on the p-17 antigen discriminated between known positive and negative sera from different cattle populations, breeding cattle and calves. Secondly, the p17 antigen detected fluctuations in the antibody levels and seroconversion in naturally- and experimentally-infected cattle. Significant differences in p-17 antigen recognition were observed between naturally infected aborting and non-aborting cattle, as well as significant antibody fluctuations over time in experimentally infected cattle, which varied between groups. Furthermore, the results obtained with WB-p17 are in accordance with the results obtained with the IFAT, as high agreement values were obtained when all bovine subpopulations were included (kappa = 0.86).

Trypanosoma cruzi strains isolated from human, vector, and animal reservoir in the same endemic region in Mexico and typed as T. cruzi I, discrete typing unit 1 exhibit considerable biological diversity

In this study, three strains of Trypanosoma cruzi were isolated at the same time and in the same endemic region in Mexico from a human patient with chronic chagasic cardiomyopathy (RyC-H); vector (Triatoma barberi) (RyC-V); and rodent reservoir (Peromyscus peromyscus) (RyC-R). The three strains were characterized by multilocus enzyme electrophoresis, random amplified polymorphic DNA, and by pathological profiles in experimental animals (biodemes). Based on the analysis of genetic markers the three parasite strains were typed as belonging to T. cruzi I major group, discrete typing unit 1. The pathological profile of RyC-H and RyC-V strains indicated medium virulence and low mortality and, accordingly, the strains should be considered as belonging to biodeme Type III. On the other hand, the parasites from RyC-R strain induced more severe inflammatory processes and high mortality (> 40%) and were considered as belonging to biodeme Type II. The relationship between genotypes and biological characteristics in T. cruzi strains is still debated and not clearly understood. An expert committee recommended in 1999 that Biodeme Type III would correspond to T. cruzi I group, whereas Biodeme Type II, to T. cruzi II group. Our findings suggest that, at least for Mexican isolates, this correlation does not stand and that biological characteristics such as pathogenicity and virulence could be determined by factors different from those identified in the genotypic characterization

Description of Micropygomyia (Micropygomyia) ancashensis sp. nov. and the female of Lutzomyia (Helcocyrtomyia) chavinensis Pérez & Ogusuku (Diptera, Psychodidae, Phlebotominae) from Ancash department, Peru

A male of a new species Micropygomyia (Micropygomyia) ancashensis sp. nov. and a female of the Lutzomyia (Helcocyrtomyia) chavinensis Pérez & Ogusuku, 1999 captured in the Antonio Raymondi province, department of Ancash, Peru are described and illustrated. The new species belongs to the cayennensis series, being closest to Mi. lewisi (Feliciangeli Ordoñez & Férnandez) though presenting highly sclerotized pseudotracheae on the labella that seem to constitute an autapomorphy among American Phlebotominae, and a clypeus almost completely covered with setae, as in Warileya. The female of Lu. chavinensis is close to those of Lu. blancasi Galati & Cáceres 1990, Lu. noguchii (Shannon, 1929), and Lu. pallidithorax Galati & Cáceres 1994.

Prevalence and resistance mutations of non-B HIV-1 subtypes among immigrants in Southern Spain along the decade 2000-2010.

Most of the non-B HIV-1 subtypes are predominant in Sub-Saharan Africa and India although they have been found worldwide. In the last decade, immigration from these areas has increased considerably in Spain. The objective of this study was to evaluate the prevalence of non-B subtypes circulating in a cohort of HIV-1-infected immigrants in Seville, Southern Spain and to identify drug resistance-associated mutations. METHODS: Complete protease and first 220 codons of the reverse transcriptase coding regions were amplified and sequenced by population sequencing. HIV-1 subtypes were determined using Stanford University Drug Resistance Database, and phylogenetic analysis was performed comparing multiple reported sequences. Drug resistance mutations were defined according to the International AIDS Society-USA. RESULTS: From 2000 to 2010 a total of 1,089 newly diagnosed HIV-1-infected patients were enrolled in our cohort. Of these, 121 were immigrants, of which 98 had ethical approval and informed consent to include in our study. Twenty-nine immigrants (29/98, 29.6%) were infected with non-B subtypes, of which 15/29 (51.7%) were CRF02-AG, mostly from Sub-Saharan Africa, and 2/29 (6.9%) were CRF01-AE from Eastern Europe. A, C, F, J and G subtypes from Eastern Europe, Central-South America and Sub-Saharan Africa were also present. Some others harboured recombinant forms CRF02-AG/CRF01-AE, CRF2-AG/G and F/B, B/C, and K/G, in PR and RT-coding regions. Patients infected with non-B subtypes showed a high frequency of minor protease inhibitor resistance mutations, M36I, L63P, and K20R/I. Only one patient, CRF02_AG, showed major resistance mutation L90M. Major RT inhibitor resistance mutations K70R and A98G were present in one patient with subtype G, L100I in one patient with CRF01_AE, and K103N in another patient with CRF01_AE. Three patients had other mutations such as V118I, E138A and V90I. CONCLUSIONS: The circulation of non-B subtypes has significantly increased in Southern Spain during the last decade, with 29.6% prevalence, in association with demographic changes among immigrants. This could be an issue in the treatment and management of these patients. Resistance mutations have been detected in these patients with a prevalence of 7% among treatment-naïve patients compared with the 21% detected among patients under HAART or during treatment interruption.

Validation of the spanish version of the multiple sclerosis international quality of life (musiqol) questionnaire

BACKGROUND: The Multiple Sclerosis International Quality Of Life (MusiQoL) questionnaire, a 31-item, multidimensional, self-administrated questionnaire that is available in 14 languages including Spanish, has been validated using a large international sample. We investigated the validity and reliability of the Spanish version of MusiQoL in Spain. METHODS: Consecutive patients with different types and severities of multiple sclerosis (MS) were recruited from 22 centres across Spain. All patients completed the MusiQoL questionnaire, the 36-Item Short Form (SF-36) health survey, and a symptoms checklist at baseline and 21 days later. External validity, internal consistency, reliability and reproducibility were tested. RESULTS: A total of 224 Spanish patients were evaluated. Dimensions of MusiQoL generally demonstrated a high internal consistency (Cronbach's alpha: 0.70-0.92 for all but two MusiQoL domain scores). External validity testing revealed that the MusiQoL index score correlated significantly with all SF-36 dimension scores (Pearson's correlation: 0.46-0.76), reproducibility was satisfactory (intraclass correlation coefficient: 0.60-0.91), acceptability was high, and the time taken to complete the 31-item questionnaire was reasonable (mean [standard deviation]: 9.8 [11.8] minutes). CONCLUSIONS: The Spanish version of the MusiQoL questionnaire appears to be a valid and reliable instrument for measuring quality of life in patients with MS in Spain and constitutes a useful instrument to measure health-related quality of life in the clinical setting.

Serological diagnosis of Chagas disease: evaluation and characterisation of a low cost antigen with high sensitivity and specificity

In spite of evident progress in the serology of Chagas disease, the requirement for new diagnostic antigens persists. We have evaluated different antigens obtained from Trypanosoma cruzi grown in medium rich in nutrients or under nutrient stress, autoclaved or sonicated and fractionated by differential centrifugation. The resulting antigens were evaluated for diagnosis of Chagas disease using ELISA. Immunofluorescence of the parasites demonstrated that nutrient stress induced changes in the distribution and density of antigens recognised by a pool of sera from experimentally infected mice. When evaluated using ELISA, it was evident that most fractions had good sensitivity but poor specificity. Surprisingly, the best specificity and sensitivity was observed with parasites cultured under nutrient stress and autoclaved. Furthermore this antigen had low cross reactivity with sera from other parasitic diseases, Leishmaniasis in particular. Western blot analysis demonstrated that autoclaving seems to non-specifically eliminate cross-reactive antigens. In conclusion, autoclaving epimastigotes of T. cruzi, after nutrient stress, allowed us to obtain an antigen that could be used in the serological diagnosis of Chagas disease.

Eficacia, Coste-efectividad y efectos sobre la calidad de vida de la suplementación nutricional.

This article summarizes the main results and conclusions presented in the Symposium "Nutritional supplementation: evidences and experiences" that took place in the XXIIIrd SENPE Congress (2008). Protein energy malnutrition, that can affect 30-50% of hospitalized patients, increases both time of hospitalization and costs of medical care of this kind of patients. There is a lot of scientific evidences demonstrating that the use of nutritional supplementation improves nutritional status or prevents malnutrition in those patients who do not meet their nutritional needs with a conventional diet or an adapted one with no replacing intake from normal food. This is strengthened by the results that demonstrate the rol of nutritional supplements improving nutritional and functional parameters. Current bibliographic reviews focused on certain clinical frameworks (i.g. geriatrics, oncology), prove that nutritional supplements reduce complications related to pathology and to nutritional status, and also reduce length of hospitalization and mortality. More studies regarding to efficacy of oral nutritional supplements are needed. These studies should be carried out with a period of follow-up longer than the current published studies have. As well as effective, nutritional supplements become a save therapeutic intervention with no important adverse events that, according to bibliography, improve patient's functionality and quality of life. It is worth mentioning that nutritional supplements can be effective on certain kind of patients, for instance, malnourished elderly or elderly in risk of malnourishment, and hospitalized surgical patients. Scientific literature refers that it is necessary to carry out more studies, with an accurate methodology, which assess the effect of nutritional supplements on quality of life and its cost-effectiveness on malnourished patients regarding specific clinical situations. That would allow physicians to make clinical decisions based on evidences and cost analysis.
