Abstract: until recently grape cultivars were identified based entirely on ampelographic criteria. currently a number of molecular techniques based on pcr can be applied for exhaustive genetic analysis on plants. these methods proceed through the direct analysis of dna, in this way avoiding the interference due to environmental interactions. in this paper the application of rapd and aflp for the analysis of genetic diversity in a group of more than 50 grape cultivars is presented. using 18 rapd primers, 103 information bands were identified, corresponding to 29.9% of polymorphism. in comparison, using only four aflp primers produced 86 information bands, with a very similar percentage of polymorphism (29.6%). both methodologies exhibited an adequate degree of reproducibility, evaluated on a collection of 48 cabernet sauvignon clones. the dendrograms based on these data sets graphically depicted the ability of both methods to differentiate all the cultivars studied. in the case of cabernet sauvignon clones, aflp permitted the identification of a number of differences that could be related to morphological differences detected among these clones, such as cluster length. the comparison of both methods, principally related to their ability to differentiate cultivars and clones, suggests that aflp is the more adequate method for both purposes. nevertheless, both methods could be implemented, given that under controlled conditions appropriate levels of polymorphism and reproducibility are displayed

Abstract: pancreatic tumors are extremely rare, specially in children, where the páncreas pseudo-papillary tumor corresponds to 1% of primary pancreatic tumors, characterized by its low malignant potential. we report the case of a solid páncreas pseudo-papillary tumor in a 5 year-old female patient, presenting with prolonged abdominal pain. an abdominal ultrasonography and computed tomography were performed, showing 2 tumors at the páncreas head and tail, with normal tumor markers (alpha-fetoprotein, carcinoembryonic antigen, p-hcg). the surgical treatment consisted on distal pancreatectomy with tumor enucleation at the páncreas head and tail, afterwards presenting acute pancreatitis that was medically treated. the biopsy confirmed páncreas solid pseudo-papillary tumor. in the 22 months follow-up period, the patient has remained disease-free

Abstract: Objetivo: Las neoplasias de páncreas son muy infrecuentes, más aún en la edad pediátrica, y el tumor sólido pseudopapilar de páncreas corresponde alrededor del 1% de los tumores primarios de páncreas, caracterizándose por su bajo potencial maligno. Reportamos el caso clínico de un tumor sólido pseudopapilar de páncreas en paciente pediátrico. La paciente es una ni a de cinco a os, la cual consultó por dolor abdominal prolongado, dentro de su estudio se realizó ecogra a y escáner abdominal demostrando dos masas en cabeza y cola de páncreas, con marcadores tumorales (alfafetoproteína, antígeno carcinoembrionario, P-HCG) normales. Se realizó pancreatectomía distal y enucleación del tumor de cabeza de páncreas; en postoperatorio evolucionó con pancreatitis de manejo médico. Biopsia confirmó tumor sólido pseudopapilar de páncreas. En seguimiento de 22 meses la paciente se ha mantenido libre de enfermedad. Conclusión: Ante este raro tumor de páncreas se debe realizar un completo estudio preoperatorio y es recomendable la cirugía conservadora Pancreatic tumors are extremely rare, specially in children, where the páncreas pseudo-papillary tumor corresponds to 1% of primary pancreatic tumors, characterized by its low malignant potential.

Abstract: Hasta hace un tiempo, los cultivares de vid sólo podían ser diferenciados en base a observaciones ampelográficas. Actualmente se dispone de numerosos métodos moleculares basados en PCR que permiten un exhaustivo análisis genético de las plantas analizando directamente su genoma y evitando de esta manera la interferencia de efectos ambientales. En este trabajo se presentan los resultados de la aplicación de dos de estos métodos, RAPD y AFLP, para estudiar la diversidad genética existente en un grupo de más de 50 cultivares de vid. Usando 18 partidores de RAPD se identificaron 103 bandas informativas, correspondiente a un 29,9% de polimorfismo. Por su parte, usando cuatro combinaciones de partidores de AFLP se obtuvieron 86 bandas informativas (29,6% de polimorfismo). Ambos métodos mostraron un adecuado grado de reproducibilidad, evaluada sobre una colección de clones de Cabernet Sauvignon. Los dendrogramas preparados en base a estos datos graficaron la capacidad de ambos métodos para diferenciar todos los cultivares estudiados. En el caso de los clones de Cabernet Sauvignon, AFLP permitió identificar una serie de diferencias que podrían estar asociadas a diferencias en el largo de los racimos que presentan estos clones. La comparación de ambos métodos, principalmente en cuanto a su capacidad para diferenciar cultivares y clones, sugiere que AFLP es el método más adecuado para ambos propósitos. Sin embargo, ambos métodos podrían ser implementados, dado que bajo condiciones controladas muestran apropiados niveles de polimorfismo y reproducibilidad Until recently grape cultivars were identified based entirely on ampelographic criteria.

Abstract: the present paper critically approaches the dogmatic construction of the chilean taxpayer's law. it states that the mentioned law is found anchored to judicial categories that belong to the past century, and this law reproduces the prior knowledge when the present chilean political constitution comes into effect and in the best cases some new elements are included under a conceptual frame that has been overcome. therefore, it is necessary to revise it according to the advances of the national constitutionalism. this is fundamental to properly protect the rights of the taxpayers according to the constitutionality bloc. the first two chapters approach the tax power and the constitutional guarantees of the taxpayer in the national law. chapter iii explains the general aspects of the european community control and the taxpayers guarantees in mentioned legal regulation. chapter iv outlines a new vision of the systematic guarantees of the taxpayers, for which aspects of the actual state of the constitutionalism are studied for the purpose of rebuilding the source system of the tax law and its rules of interpretation. next, a method agreeing with this vision is explained including the constitutional guarantees and the fundamental rights of the taxpayer like the tax power.

Abstract: the present paper communicates about the normative configuration and the doctrinal and jurisprudential elaboration of the principle of capacity to pay in spain. the author seeks to make known in chile a legal institution that is recognized in the european legal systems and which constitutes the essential basis of their tax systems, in order to be incorporated in chile through an own theoretical elaboration on the basis of the national normative materials. by the previous thing, the author gives reasons to justify this incorporation and provides elements to adapt this principle in the chilean legal order. the issues contained in this communication are vast and complex, they are inserted in the theory of the principles of tax justice, and is the reason for which the author builds his speech through several independent steps in a series of papers.

Abstract: this paper seeks to identify the intrinsic ideas in the chilean constitutional jurisprudence about the material principles of taxation, particularly, equality and non-confiscatory tax. it is addded the principle of economic capacity, as a necessity of the research program. to achieve the goal, some elements of discourse analysis are used. but, essentially, to seek to contribute to the dogmatism of the material principles of taxation, an effort until now neglected in our country, and in this perspective, the method used to analyze the jurisprudence necessarily will differ from other studies. this work does not follow the traditional method, in the sense of linking this matter to the constitutional theory to the public economic order. in the conclusion, it is structured what according to the author are the central elements of the jurisprudential conception of the material principles of taxation.

Abstract: El presente trabajo busca identificar las ideas ínsitas en la jurisprudencia constitucional chilena acerca de los principios materiales tributarios, particularmente, la igualdad tributaria y la no confiscatoriedad. Se a ade al principio de capacidad económica, por necesidades del programa de investigación. Para lograr el objetivo, se utilizan algunos elementos propios del análisis del discurso. Pero, y es lo esencial, se busca aportar a la dogmatización de los principios materiales tributarios, esfuerzo hasta ahora desatendido en nuestro medio, y en tal perspectiva, el método usado para analizar la jurisprudencia necesariamente se diferenciará de otros estudios. El presente trabajo tampoco sigue el método tradicional en el sentido de vincular esta materia a la teoría constitucional del orden público económico. En la conclusión se estructuran los que son, a juicio del autor, los elementos centrales de la concepción jurisprudencial de los principios materiales tributarios.
