Aspectos biológicos y culturales del patrón genético de no persistencia de lactasa y su relación con las prácticas alimentarias en poblaciones con ancestría amerindia de la IX región de la Araucanía
(Universidad de Chile, 2015-04-13)La no-persistencia de lactasa en edad adulta es un fenómeno que ha sido estudiado en diferentes países y etnias desde 1960. Particularmente en Latinoamérica, el mestizaje entre población indígena y europea tras la conquista ... -
DNA from human ancient bacteria: a novel source of genetic evidence from archaeological dental calculus
(2013)We report a molecular methodology to obtain and analyse ancient bacterial DNA from archaeological dental calculus. Recent and archaeological DNA samples, as old as 4000 BP, were successfully extracted and amplified with ... -
Estructuración genética en Santiago de acuerdo al estrato socio-económico
(Universidad de Chile, 2013) -
Evaluando nuevos enfoques metodológicos para el estudio de dietas en poblaciones prehistóricas. Microbioma oral y PIXE
(Universidad de Chile, 2013-04)Estudiar las costumbres alimentarias en una población determinada nos da cuenta no sólo de las estrategias de subsistencia empleadas por ella, también puede dar luces sobre estratificación social, o el desarrollo de distintas ... -
Evolución de los filotinos (Rodentia, Muridae) en los Andes del Sur
(2001)La tribu Phyllotini es un grupo avanzado de 46 especies endémicas entre los Muridae de América del Sur que, estando adaptado a sus ambientes xéricos, parece haber tenido el Altiplano Sur como área de diferenciación original ... -
Frecuencia y Expresión de la Tolerancia e Intolerancia a la Lactosa en Población de la Isla de Pascua, Chile
(Universidad de Chile, 2011-01-23)La lactosa es el azúcar de la leche, sustancia procesada en nuestro organismo por una enzima llamada lactasa que se ubica en el ápice de los ribetes del intestino delgado. Al igual que la mayoría de los mamíferos, los ... -
Genetic variants and alcohol intake patterns in university population in Santiago of Chile

Genomic compatibility between two phyllotine rodent species evaluated through their hybrids
(1999)In order to investigate the genomic compatibility between allopatric rodent species, Phyllotis durivini and Pliyllotis mugister, we have studied several cytogenetic and reproductive features of their laboratory hybrids. ... -
Independent Origins of New Sex-Linked Chromosomes in the melanica and robusta Species Groups of Drosophila
(2008-01)Background: Recent translocations of autosomal regions to the sex chromosomes represent important systems for identifying the evolutionary forces affecting convergent patterns of sexchromosome heteromorphism. Additions ... -
Influence of Physician Factors on the Effectiveness of a Continuing Medical Education Intervention
(2006)Background and Objectives: Continuing medical education (CME) is essential for improving the quality of care in primary health care settings. This study’s objective was to determine how the characteristics of family ... -
Molecular phylogeny and a taxonomic proposal for the genus Streptococcus
(FUNPEC, 2015)Alternative phylogenies for the genus Streptococcus have been proposed due to uncertainty about the among-species group relationships. Here, we performed a phylogenetic analysis of the genus Streptococcus, considering ... -
Nucleolar activity and distribution of ribosomal genes in phyllotis rodent species and their laboratory hybrids
(University of California, 2007)The expression of nucleolar organizer regions (NORs), distinguished through silver staining procedures, and the distribution of ribosomal genes, detected by fluorescent in situ hybridization with a ribosomal DNA probe, ... -
Patrones de consumo y genotipos determinantes de la tolerancia al alcohol: estudio en estudiantes universitarios de Santiago de Chile
(Sociedad Médica de Santiago, 2015)Background: Alleles involved in inefficient (ADH1B2*2 and ALDH2*2) or efficient (SNP6, ADH4 gene) alcohol metabolism may influence the risk of alcoholism. Alcoholism susceptibility has been classified as protector ... -
Patrones de consumo y variantes genéticas involucradas en la tolerancia del alcohol en población Universitaria de Santiago de Chile
(Universidad de Chile, 2014-10)El alcohol es ampliamente consumido a nivel mundial. Los patrones de consumo y abuso de esta sustancia varían alrededor del mundo. Además en poblaciones humanas modernas existe heterogeneidad en la capacidad metabólica ... -
Phylogenetic relationships among tribes in Xylocopinae (Apidae) and implications on nest structure evolution
(2010-07)The subfamily Xylocopinae has been recognized as the most basal lineage within the family Apidae, comprising four tribes; Allodapini, Ceratinini, Xylocopini and Manueliini. Relationships among the tribes are not well ... -
