| The somatic cloning by transfer of the nuclei of differentiated adult cells to previously enucleated oocytes is a promising technique for the production of embryos of high genetic value. The better mastering of somatic cloning gives us the possibility to produce embryos from endangered species. The huemul is an Andean native deer, that has been declared an endangered species, it holds a great patrimonial value and it is a Chilean national emblem. In Chile the huemul has the status of protected animal on thirteen Parks and National Reserves managed by Corporacion Nacional Forestal (CONAF). This protection, however, is considered insufficient due to the few geographical connections between the different protected areas. Furthermore, a great proportion of... |

| La dismetría de la pelvis es frecuente en los adolescentes y puede ser un factor que provoque dolores en la columna vertebral y estar asociada a escoliosis funcionales de la región lumbar. Estas disfunciones de la columna vertebral producen incapacidad laboral, son de alta prevalencia en el mundo. Este problema de salud pública es de origen multifactorial afecta a la mayoría de las personas principalmente en la edad media de la vida. El propósito del estudio fue conocer cómo se comportan nuestros adolescentes con respecto a la variable dismetría pélvica. Para ello se analizaron 49 radiografías panorámicas de columna vertebral, de escolares entre 13 y 17 años de ambos géneros, 24 hombres y 25 mujeres, de la ciudad de Temuco, Chile. Del total de sujetos, 33... |

| In adult salmon of the sea centres in southern Chile, a jaw deformation (JD) has been identified. It affects the dental and hyomandibular bones, which bend ventrally up to 90° of their normal position. The deformation affects also the dental articular bone. This pathology is related to weight loss and increased mortality of the salmons. It was empirically postulated that a probable cause for this anomaly was food from vegetal origin in the diet of the fishes (which are carnivores) Therefore, the present work aims at comparing the biostructure of jaw bone of salmons fed either with vegetal (soja and gluten) formulation or animal formulation, mostly fish powder. Fifty specimens were analyzed from Puerto Montt, 35 having JD and 15 normal control.... |

| The objective of this project is to produce pudu embryos, obtained by means of fibroblast transfer taken from the ear of one animal, to the oocytes of a domestic ruminant such as cattle. In further work, the pudu embryos will be transferred to the uterus of synchronized recipient females of another species. Biopsies 1mm in size were obtained from the outer rim of the ear of two male pudu deer belonging to the Buin Zoological park, Santiago, Chile. The cell lines have been established and kept according to protocols used in cattle. The oocytes are obtained through a puncture in the oocyte-cumulus complex (OCC) from cow ovaries recovered from the butcher. Each oocyte is enucleated and fused with an isolated fibroblast which is inserted beneath the pellucid... |
