Friendly Settlements in the Framework of the Inter- American Human Rights System

The Inter-American system for the protection of human rights provides that disputesbetween States and victims of human rights violations or their representatives can beresolved through a friendly settlement. In this arrangement, conducted before the regionalorgans of protection of human rights, the State accepts its international responsibility,commits itself to investigate and judge the responsible and makes commitmentson compensation to the offended, the victims, on his part, renounce to take the caseto the Inter-American Court of Human Rights, and the Inter-American Commissionmonitors the legal consistency of the agreement and holds the role of independentobserver. What are these agreements, what possibilities and limitations provide to theopposing parties and, above all, what kind of reparation offer to victims of humanrights violations are issues to resolve in this article.

Turing’s imitation game and human thought

In 1950, the English mathematician Alan Mathison Turing proposed the basis of what some authors consider the test that a machine must pass to establish that it can think. This test is basically a game; nevertheless, it has had great infl uence in the development of the theories of the mind performance. The game specifications and some of its repercussions in the conception of thinking, the consciousness and the human will, will be ramifications of the path that will take us through the beginning of the artificial intelligence, passing along some of its singular manifestations, to culminate in the posing of certain restrictions of its fundaments.

Neural networks of human nature and nurture

Neural network methods have facilitated the unification of several unfortunate splits in psychology, including nature versus nurture. We review the contributions of this methodology and then discuss tentative network theories of caring behavior, of uncaring behavior, and of how the frontal lobes are involved in the choices between them. The implications of our theory are optimistic about the prospects of society to encourage the human potential for caring. 

Colamus humanitatem : Nurturing human nature

In an essay on anger, the ancient philosopher Seneca warns of the futility of harboring negative emotions given the imminence of death—the ultimate human equalizer. Ancient philosophers like Seneca believed that emotions are based on cognitions (beliefs) and are therefore modifiable through spiritual exercises. Modern research shows that the emotional and cognitive aspects of human psychology are malleable (nurture), but also require gene expression (nature). A parallel between individual behavior and socio-political forces suggests a framework for the current environmental crisis— another human equalizer. Two critical questions are suggested: Is the amassed experience of the last few centuries sufficient to lead to corrective measures that would avoid environmental degradation? Or would a catastrophic event with significant longterm environmental degradation have to occur before corrective measures reach consensus at the socio-political level? 

A few philosophical ruminations on the human condition and choosing to live well

The notion that life is meaningful through choosing to live well has historically received substantive attention in various philosophical circles, notably the ancient Greek philosophers Socrates, Plato, and Aristotle, and more recently several of the existentialists. In some respects, the idea of choosing to live well is a “thematization” of two widely-recognized, independent components of a meaningful life: happiness and authenticity. I develop this notion of choosing to live well by exploring, developing, and relating these conceptions of happiness and authenticity. By appealing to a very basic account of human nature that has found favor among a great number of people, I show how happiness and authenticity complement each other as conditions for the possibility of living meaningfully.

Human development in an evolutionary perspective

This article presents an evolutionary perspective to the study of human development. Some general assumptions for the study of development are discussed and the principal building blocks of evolutionary psychology are presented. One of them is that there is a universal human nature (which is modulate also by particular conditions of each context) and the cognitive architecture of human beings is the resulted of interactions between genes and environment. Based on those, and other assumptions, directions for the study of child development in an evolutionary stance are discussed, along with the considerations of context and development. Thus, it is assumed there is a relationship between phylogenies and ontogenetic development (the ontogenesis needs to be understood also as a product of evolution), considering the inseparability of biological, socio-cultural, cognitive emotional aspects that constitute this development. It has been concluded that the evolutionary developmental psychology has scientific relevance because it broadens our vision on human development.

Art and human nature

This article presents a visual artist’s point of view about art. This view confronts the Eurocentric traditional cannon with some ignored, but valuable traditions, thus proposing a contra-canon. These ideas are examined on the light of a variety of sources, including prehistoric, pre-Columbian, and 20th century art expressions, in a variety of media, from sculpture to literature. Recent art expressions are characterized by their incorporation of minority values and perspectives that challenge “universal” views. Using samples of works from Latino and African American artists, the author shows that, even today, art is a means to know the world and its people, to exhibit personal life, to create personal symbolism, and to show one’s identity or the search for it. Like the human nature it represents, art has multiple faces.

The Inner Meaning of Outer Space: Human Nature and the Celestial Realm

Kant argued that humans possess a priori knowledge of space; although his argument focused on a physics of bodies, it also has implications for a psychology of beings. Many human cultures organize stars in the night sky into constellations (i.e., impose structure); attribute properties, behaviors, and abilities to objects in the celestial realm (i.e., impose meaning); and use perceived regularity in the celestial realms in development of calendars, long-range navigation, agriculture, and astrology (i.e., seek predictability and control). The physical inaccessibility of the celestial realm allows a potent source of metaphor, and also allows projection of myths regarding origin and ascension, places of power, and dwelling places of gods, immortals, and other souls. Developments in astronomy and cosmology influenced views of human nature and the place of humanity in the universe, and these changes parallel declines in egocentrism with human development. Views regarding alleged beings (e.g., angels, extraterrestrials) from the celestial realm (and to how communicate with such beings) are anthropocentric and ignore evolutionary factors in physical and cognitive development. It is suggested that in considering views and uses of the celestial realm, we learn not just about the universe, but also about ourselves. 

Determinación de anomalías cromosómicas y secuencias de ADN amplificadas en cáncer de mama

El cáncer de mama en Colombia, es la tercera causa de muerte en la población en general y la segunda en mujeres. En el año 2002 el 40.5% de los casos se presentaron en mujeres menores de 50 años (Pardo, et al. 2003). El cáncer de mama resulta de múltiples factores, entre los que se incluyen cambios sucesivos en el genoma de células epiteliales originalmente normales, que pueden conducir a la activación de oncogenes, inactivación de genes supresores de tumor y pérdida de función de genes reparadores de daños al ADN. Estas alteraciones pueden también ser producto de anomalías cromosómicas tales como monosomías, trisomías, translocaciones, inversiones, pérdida de material genético y amplificaciones que también afectan la expresión de genes (1) (2) (3) (4). Sin embargo, el orden de aparición de los diferentes eventos no está completamente dilucidado. En este estudio se determinaron las anomalías cromosómicas y secuencias de ADN amplificadas en pacientes con cáncer de mama, tanto en muestras de sangre periférica como de tumor de mama de 30 pacientes. En las dos líneas celulares analizadas se observó una alta frecuencia de monosomías principalmente de los cromosomas X, 6, 7, 9, 17, 19 y 22. Hay una asociación entre las monosomías de los cromosomas 17 y 22 con el estado negativo para los receptores de estrógenos y progestágenos (p=0.027, p=0.050). También se encontró asociación entre la monosomía del cromosoma 19 con edad avanzada (p=0.034), observándose formas más agresivas de la enfermedad cuando ésta estuvo presente. Las monosomías fueron características de carcinomas ductales infiltrantes de todos los grados. En los demás tipos de carcinoma su frecuencia fue más baja. En el presente estudio se encontró una asociación significativa entre algunas anomalías cromosómicas y la enfermedad, no reportadas anteriormente, como fueron algunas monosomías, fragilidades y roturas cromosómicas y cromatídicas. La alta frecuencia de fragilidades encontradas tanto en sangre periférica (fra 9q12 p=0.001 y fra 3p14 p= 0.38) como de fragilidades expresadas espontáneamente (no inducidas por el uso de reactivos específicos) en muestras de tumor de mama (fra 1p11 p= 0.001, fra 2q11 p= 0.002), pueden ser el reflejo de una alta inestabilidad cromosómica en el genoma de estos pacientes, mostrando lautilidad de los estudios de fragilidad en la determinación de individuos en alto riesgo de desarrollar cáncer de mama. En ensayos de FISH no se observaron amplificaciones de los genes ERBb2 y c-myc en los pacientes analizados. Esto concuerda con lo encontrado en la literatura en donde se ha reportado, para este tipo de tumores, una sobre expresión de la proteína sin amplificación del gen, explicada por desregulación de la expresión del gen, a su vez posiblemente debida a mutaciones en la región promotora o a alteraciones, que conducen a un aumento de la tasa de transcripción (5) (6) (7). Los resultados obtenidos, aunque preliminares, aportan nuevos marcadores cromosómicos que pueden orientar el diagnóstico, pronóstico y tratamiento de esta patología.

Identification of the Learning Styles in the Students of Exercise Physiology in the Rehabilitation and Human Development Faculty

The object of this study is to identify the learning styles (LS) used by the students of the subject of physiology of the exercise of the program of Physiotherapy, with the purpose of establishing a direct relationship later on between the learning styles and the possible pedagogic strategies that but they favor the compression of the physiology of the exercise 48 subject of second and third year of career they were interviewed through the instrument standardized compound number (CHAEA). This study carried out an analysis descriptive and of typical deviation of the data. They were differences statistically significant in the styles of active and reflexive learning, in front of the Theoretical and pragmatic styles what puts in evidence the necessity to generate pedagogic strategies inside the subject that this chord with the tendency of the active and reflexive learning of the students.

Structural Chromosomal Alterations Induced by Dietary Bioflavonoids in Fanconi Anemia Lymphocytes

Introduction Fanconi anemia is an autosomal recessive disease characterized by a variety of congenital abnormalities, progressive bone marrow failure, increased chromosomal instability and higher risk to acute myeloid leukemia, solid tumors. This entity can be considered an appropriate biological model to analyze natural substances with possible genotoxic effect. The aims of this study were to describe and quantify structural chromosomal aberrations induced by 5 flavones, 2 isoflavones and a topoisomerase II chemotherapeutic inhibitor in Fanconi anemia lymphocytes in order to determine chromosomal numbers changes and/ or type of chromosomal damage. Materials and methods Chromosomes stimulated by phytohaemagglutinin M, from Fanconi anemia lymphocytes, were analysed by conventional cytogenetic culture. For each chemical substance and controls, one hundred metaphases were evaluated. Chromosomal alterations were documented by photography and imaging analyzer. To statistical analysis was used chi square test to identify significant differences between frequencies of chromosomal damage of basal and exposed cell cultured a P value less than 0.05. Results There were 431 chromosomal alterations in 1000 metaphases analysed; genistein was the more genotoxic bioflavonoid, followed in descendent order by genistin, fisetin, kaempferol, quercetin, baicalein and miricetin. Chromosomal aberrations observed were: chromatid breaks, chromosomal breaks, cromatid and chromosomal gaps, quadriratials exchanges, dicentrics chromosome and complex rearrangements. Conclusion Bioflavonoids as genistein, genistin and fisetin, which are commonly present in the human diet, showed statistical significance in the number of chromosomal aberrations in Fanconi anemia lymphocytes, regarding the basal damage.

Human morphology from morphology

The purpose of this article is to explain the grammatical rules of the Nomina Anatomica. Meanwhile, there is a new synchronic formulation to the Nomina Anatomica, according to systematic cases and Latin declinations with applications to the entity of the human body, and very important indications about the diachronic grammar. Therefore, the morphologic grammar plays a very important role to the interpretations of Human Anatomy

Exposición a plaguicidas en los habitantes de la ribera del río Bogotá (Suesca) y en el pez Capitán

Objetivo: considerando el elevado uso de plaguicidas en Colombia y los efectos nocivos que produce la exposición a estas sustancias para la salud humana y el ambiente, se realizó un estudio para la determinación de biomarcadores de exposición y efecto de plaguicidas en la población de Suesca que habita en la ribera del río Bogotá, de los niveles de plaguicidas en muestras de agua del río tomadas en el mismo municipio y en muestras de pez “Capitán de la sabana” (Eremophylus mutisii) capturado en dicha zona. Materiales y métodos: se realizaron determinaciones para organofosforados, carbamatos, ditiocarbamatos y organoclorados También se exploró, mediante una encuesta, la exposición ocupacional a plaguicidas y el conocimiento y utilización de medidas de protección personal en su actividad laboral. Adicionalmente, se examinó el hábito de la pesca de pez Capitán y su consumo en la dieta de los habitantes de esta zona del río. Resultados: los resultados muestran la presencia de plaguicidas organoclorados y organofosforados en el río y en el tejido de los peces y organoclorados y etilentiourea en las muestras biológicas humanas. En el estudio participaron trabajadores directamente expuestos a plaguicidas, quienes manipulan productos de alta toxicidad; en su mayoría conocen y emplean las medidas de protección personal e higiene industrial. Conclusiones: existe contaminación por plaguicidas en la cuenca alta del río Bogotá que afecta a la fauna y a las poblaciones ribereñas. Es necesario promover mejores medidas para el cuidado del ambiente, para la protección y para el autocuidado de las personas que manipulan plaguicidas en la zona.

Interdisciplinary Pedagogical Experience for Health Human Resources Focused on the Holistic Promotion of Health and the Prevention of the Disease

The object of this experience is to offer the students the opportunity to take part in the construction of a pedagogic strategy centred on the ludic, for the promotion of the integral health and the prevention of the disease with an educational community; directed to supporting and qualifying the well-being so much individually as group. The project is designed to five years, about interdisciplinary character (Speech Therapy, Medicine, Psychology, Nursery, Occupational Therapy), interinstitutional (Universidad del Rosario, Universidad de San Buenaventura y Universidad de Cundinamarca) and intersectorial (Education and Health). It considers the different actors of the educational community and school and the home as propitious scenes for the strengthening potential, beside being the fundamental spaces for the construction of knowledges and learnings concerning the integral health. To achieve the target, one has come constructing from the second semester of 2003, one pedagogic strategy centred on the ludic and the creativity, from which they are planned, they develop and evaluate the actions of promotion of skills, values, behaviors and attitudes in the care of the health and the prevention of disease, orientated to the early, opportune and effective detection of risk factors and problematic of the development that they affect the integral health. The above mentioned strategy raises a so called scene Bienestarópolis: A healthy world for conquering, centred on prominent figures, spaces and elements that alternate between the fantasy and the reality to facilitate the approximation, the interiorización and the appropriation of the integral health. Across this one, the children motivated by the adults enter an imaginary world in that theirs desires, knowledges and attitudes are the axis of his development. Since Vigotsky raises it, in the game the child realizes actions in order to adapt to the world that surrounds it acquiring skills for the learning. The actions of the project have involved 410 children and 25 teachers, of the degrees Zero, The First and The Second of basic primary; 90 parents of family, and an average of 40 students and 8 teachers of the already mentioned disciplines.

Epigenética: definición, bases moleculares e implicaciones en la salud y en la evolución humana

La Epigenética se refiere a los cambios heredables en el ADN e histonas que no implican alteraciones en la secuencia de nucleótidos y modifican la estructura y condensación de la cromatina, por lo que afectan la expresión génica y el fenotipo. Las modificaciones epigenéticas son metilación del ADN y modificaciones de histonas. Objetivo: hacer una revisión de la literatura sobre el concepto de epigenética y su impacto en la salud. Materiales y métodos: se realizó una revisión de la bibliografía sobre el concepto de epigenética, sus bases biológicas, el impacto sobre la salud y la enfermedad y su relación con la evolución. Resultados: los mecanismos epigenéticos han cobrado cada vez más importancia debido a la creciente asociación con enfermedades complejas y comunes, así como por su impacto en la salud de generaciones futuras y en la evolución humana. Conclusiones: la Epigenética tiene un claro impacto en la salud del individuo, en la de su descendencia y en la evolución de la especie humana.
