TITLE: The Poetic Trajectory of Adolfo Alonso Ares . TíTULO: La trayectoria poética de Adolfo Alonso Ares.
Armando López Castro
Castilla : Estudios de Literatura , 2010,
Abstract: ABSTRACT: The poems of Adolfo Ares reveal a natural voice, which resonates with the same cosmic rhythm articulated throughout all his writing. From a linguistic point of view, it could be said that his proximity to the spoken word, without which no renewal is possible, enables him to create a dynamic language in a continual process of transformation, through which each poetic experience acquires a new sense. This has been the function of art since antiquity, to locate humanity within the vital rhythm of the universe, which in turn forms the inspiration for all poetry. RESUMEN: Los poemas de Adolfo Ares revelan una voz de lo natural, una resonancia de un mismo ritmo cósmico que articula tosa su escritura. Desde el punto de vista lingüístico, se puede decir que la cercanía del poeta a la lengua hablada, sin la cual no hay renovación posible, le permite crear un lenguaje dinámico, en continua transformación, con el cual cada experiencia poética adquiere un sentido nuevo. Tal ha sido la función del arte desde los tiempos más antiguos: integrar al hombre en el ritmo del universo, que a su vez ha de animar a la obra poética en su conjunto.

Abstract: Cell therapy has shown beneficial effects on ventricular function and tissue regeneration in patients with acute and chronic myocardial infarction, although with diverse grades of variability in the results, possibly by proportion, subtype and cell cycle status. Objective: Identify and phenotypically characterize, via CXCR4 and SDF-1 expression, the bone marrow cell subpopulations that are mobilized into the bloodstream in patients with Acute Myocardial Infarction (AMI) and Acute Ischemia (AI) such as acute angina and Chronic Ischemia (CI) such as chronic stable angina, and also determine the cell cycle status of these cells. Method: Patients with AMI and AI were recruited in the ICCU, and patients with CI in the departments of cardiology and cardiovascular surgery. The quantification of cellular subpopulations was made by cytofluorometry with a FACS caliburcyto fluorometry (Becton Dickinson) with specific FITC-labeled anti human monoclonal antibodies against CD34, CD133, CD117, CD48, CXCR4, SDF-1 and Ki67 (Becton Dickinson). Serum concentration of IL-6 and IL-8 were determined by a sequential solid phase chemiluminescent assay performed in a SIEMENS IMMULITE 1000 Analyzer. Statistical analysis was made with the SPSS version 20.0 for Windows. A p value < 0.05 was considered as statistical significant. Results: We analyzed 174 patients. 67 had Acute Myocardial Infarction, 55 Acute Ischemia and 52 Chronic Ischemia. Total cellularity of bone marrow and SDF-1+ cells was significantly higher in patients with AMI (14.6 ± 1.5 × 103/ml) than that in AI (9.2 ± 1.3 × 103/ml) and CI (6.6 ± 1.1 × 103/ml) patients (p < 0.001). There were no significant differences in the amount of CD34+, CD117+, CD133+ and CD48+ cells between AMI (49.9 ± 3.9, 45 ± 4.7, 43.2 ± 3.7, 35.4 ± 6.7 respectively) and AI (36.7 ± 2.5, 36 ± 3.2, 33.7 ± 5.1, 32 ± 5 respectively) patients (p = 0.22 to 0.39), but interestingly in AMI and AI patients, cells were CXCR4+ in almost half of these mobilized cells, although the proportion was significantly higher in AMI patients (46.8% ± 7.1% to 55.7% ± 6.3% vs 23% ± 1.6% to 28.4% ± 2.1%, p = 0.03 to 0.05). A similar behavior was observed with the Ki67 antibody (29.9% ± 2.1% to 36.1% ± 6.3% vs 10% ± 1.2% to 24% ± 1.1%, p = 0.001 to 0.05). Bivariate analysis of the results showed a significant correlation of the cell proportion in AMI but not in AI and CI patients (p = 0.001 to 0.05; 0.12 to

Abstract: background. we do not know of studies in our city that indicate the degree of poly illicit drugs consumption in motor vehicles drivers. use of illicit drugs can explain in some cases the lack of agreement among measurement of breath alcohol test, blood alcohol concentration, and clinical examination in motor vehicles drivers when they are suspects of alcoholic intoxication. in this report we want to center on showing the use of illicit drugs and their clinical manifestations in a sample of motor vehicles drivers. objective. to determine the consumption of illicit drugs in a sample of motor vehicle drivers, when they are suspects of alcoholic intoxication. materials and methods. we took a representative sample within 68 motor vehicle drivers. we performed on all of them clinical examination, measurement of breath alcohol tests and blood alcohol concentration. also we collected urine samples. five (5) substances were investigated according to their high prevalence in our population: opiate, marijuana, cocaine, amphetamines and benzodiazepines. results.there were seven cases of illicit drug consumption: the most frequent combination found was (5-7 cases) alcohol plus marijuana. in three cases we found consumption of three illicit drugs: 2 cases have alcohol, marijuana and cocaine. only one case of alcohol, benzodiazepine and cocaine. conclusions. in the sample analyzed the use of illicit drugs was 10.14 %. the most common form of use is a depressor with a stimulant. if it is recent, it diminishes the neurological manifestations, but it does not affect the presentation nor the severity of the rotacional nystagmus. the alterations of the superior mental functions were seen to be associated with alcohol consumption plus benzodiazepines. combination of two depressors increases the motor alterations and seems that it alters the superior mental functions. in the negative clinical examinations it was concluded that there was no alcohol intoxication and no use of other psychoa

Abstract: Antecedentes. No conocemos estudios que establezcan en nuestro medio la dimensión del policonsumo en conductores de vehículo automotor. El problema del policonsumo puede explicar en algunos casos la falta de concordancia de alcoholemia, etilometria y examen clínico. En este informe queremos centrarnos en la presentación de policonsumo en la muestra y el cuadro clínico de estos conductores. Objetivo. Determinar en una muestra de conductores de Bogotá, con sospecha de intoxicación etílica, el consumo de otras sustancias psicoactivas. Material y métodos. Se tomó una muestra representativa de 68 conductores. Se les realizó el examen clínico de embriaguez, etilometria, prueba de alcoholemia en sangre y muestra de orina para estudio de estupefacientes. Se investigaron cinco sustancias según su prevalencia epidemiológica en nuestro medio: marihuana, cocaína, anfetaminas benzodiazepinas y opiáceos. Los casos positivos se correlacionaron con el examen clínico y la alcoholemia para hacer el análisis respectivo. Resultados. Se presentaron siete casos de policonsumo de 68 analizados. La combinación más frecuente (5-7 casos) encontrada es alcohol con cocaína. En tres casos hubo consumo de tres psicoactivos: alcohol+marihuana+coca (dos casos), alcohol+benzodiacepina+coca (un caso). Conclusión. En la muestra analizada el policonsumo fue del 10,3 por ciento. La combinación de un depresor con un estimulante, si es reciente, disminuye las manifestaciones neurológicas, pero no afecta la presentación ni severidad del nistagmus posrotacional. La alteración de las funciones mentales superiores se vieron asociadas al consumo de alcohol más benzodiacepinas. La combinación de dos depresores aumenta las alteraciones motoras y parece que altera las funciones mentales superiores. El examen clínico negativo parece ser sensible para descartar embriaguez alcohólica y por otros psicoactivos. Background.
