Diversidad genética y mezcla racial en los amerindios de Costa Rica y Panamá
(1993)
The genetic diversity of nine Amerindian tribes (Borne*, Bokota, Bribri, Cabecar, Gourmet, Guaymi.,
Hues's, Kuna and Teribe) from Costa Rica and Panama were analyzed using 48 loci of enzimatic systems, blood
groups and ...
In vivo and in vitro genetic evidence of involvement of neuregulin 1 in immune system dysregulation
(J Mol Med (Berl). 2010 November ; 88(11): 1133–1141, 2010-11)
Neuregulin 1 (NRG1) has been implicated in several disorders including breast cancer, multiple sclerosis, and schizophrenia. Also, recent evidence suggests that NRG1 may play a role in regulation of inflammation and immune ...
Ataxias espinocerebelosas de herencia autosómica dominante (SCAs): características, clasificación y diagnóstico
(Neuroeje, Enero-Junio 2012 Volumen 25 (1) 9-19, 2012)
The autosomal dominant spinocerebellar ataxias (SCAs,
also known as ADCAs) are a group of progressive neurodegenerative
diseases characterized by loss of balance and
motor coordination, and comprise a highly ...
Genetic contributions to circadian activity rhythm and sleep pattern phenotypes in pedigrees segregating for severe bipolar disorder
(2016-02-09)
Abnormalities in sleep and circadian rhythms are central features of bipolar disorder (BP), often persisting between episodes. We report here, to our knowledge, the first systematic analysis of circadian rhythm activity ...
Gene admixture in the Costa Rican population
(Ann Hum Genet; 67 (1) p. 71-80, 2003)
The general population of Costa Rica has sometimes been considered to be the product of an amalgamation
of groups of diverse origin. To determine the magnitude of accumulated admixture since Spanish colonization,
11 ...
When genes move farther than offspring: gene flow by male gamete dispersal in the highly philopatric bat species Thyroptera tricolor
(2013-11)
For species characterized by philopatry of both sexes, mate selection represents an important behaviour for inbreeding avoidance, yet the implications for gene flow are rarely quantified. Here, we present evidence of male ...
Estudios evolutivos y biomédicos en dos poblaciones indígenas Guaymies de Costa Rica
(Vínculos 7(1), 1-7. 1981, 1981)
A biomedical study which included genetic, demographic, nutritional and health aspects was
carried out in two amerindian Guayrni populations, Abrojo and Limoncito, located in Southeastern
Costa Rica. Both groups originated ...
Identificación de genes causales y de susceptibilidad para enfermedades de herencia Mendeliana y compleja
(Acta médica costarricense Vol 51 (1), enero-marzo 2009, 2009-01)
Los factores genéticos participan en la etiología de la mayoría de las enfermedades comunes en
la población. Las enfermedades en las que participan factores genéticos pueden ser clasificadas
en varias categorías y de ...
Blood Group, Red Cell, and Serum Protein Variation in the Cabecar and Huetar, Two Chibchan Amerindian Tribes of Costa Rica
(American Journal Human Biology ;13 (1): p. 57-64, 2001)
Genetic variation, using blood groups and red cell and serum proteins, was surveyed in the Cabecar of Chirripo and the Huetar of Quitirrisi, Costa Rica. Thirty-nine loci were screened in a sample of 91 Cabecars and 40 loci ...
Grupos sanguíneos ABO y Rh y proteínas séricas en una población amerindia, Matambú, Costa Rica
(1985-06)
Se llevó a cabo un estudio de la estructura genética de la población de Matambú, Costa Rica, utilizando marcadores genéticos de 6 loci que incluyen los grupos sanguíneos ABO y Rh y la albilmina, ceruloplasmina, haptoglobina ...
