Comportamientos antisociales: la investigación moderna aclara errores sobre la causalidad entre enfermedad mental y conductas violentas / Antisocial behaviors: the modern research explains errors about causality between mental disease and violent behavior

El fenómeno de la violencia está en aumento en todos los países del mundo y se puede hablar de epidemia social. Su causa no es específica de un único factor: sea este biológico, social, económico o ambiental. Según los resultados de la investigación moderna los comportamientos antisociales responden a una interfactorialidad y por lo tanto se presentan de manera compleja. Podemos añadir, como ulterior confirmación cientifica, la investigación realizada sobre personas con síndromes esquizofrénicos en las ciudades de Bolonia y Bouider, que demuestran que el crimen no esta mecánicamente relacionado con la enfermedad mental. En psiquiatría el enfoque multidisciplinario permite distinguir netamente el trastorno mental de la conducta violenta. La contención del fenómeno de la violencia es sólo posible con una política de salud pública interinstitucional, multidisciplinaria e interprofesional dirigida hacia la promoción de la salud, a partir de la tutela del bienestar infantil

Markers of genetic variation among the Waorani Indians of the Ecuadorian Amazon headwaters.

Until recently, the Waorani Indians of Ecuador's Amazon headwaters maintained a fierce resistance to all intruders into their territory, and as a result of their actions and reputations a population of 600 people controlled a very large territory (about 8,000 square miles). The isolation of the Waorani has resulted in a large linguistic and genetic distance from their neighbors. Our survey of red cell enzymes, immunoglobulin allotypes, and dermatoglyphics demonstrates that the Waorani are a highly inbred and homogeneous population. Of 18 red cell enzymes studied, the Waorani have a limited polymorphism for only 6. Only two Gm haplotypes (Gm1,2,17,21, Gm1,17,21) were found and 60% of those tested were homozygous for the Gm1,17,21 haplotype. All individuals were A2m (1) and 95% of these were homozygous. The Waorani's dermatoglyphic traits fell within the wide range found among other South American Indians with close affinity to the Ecuadorian Jivaro group. Despite the limitations of these genetic systems, they demonstrate that the Waorani share limited genetic traits with the neighboring Jivaro Indians and are isolated from other tribal populations in South America.
