Gender differences in perceived stress and its relationship to telomere length in Costa Rican adults
(2022-02-25)Introduction: Stress is associated with disease and reduced leukocyte telomere length (LTL). The objective of this research is to determine if self-perceived stress is associated with telomere length in Costa Rican adults ... -
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 ... -

Generational Transfers and Population Aging in Latin America
(Population and Development review 37 (Supplement): 143–157 (2011) 143, 2011)Population aging, a direct consequence of the demographic transition, is often portrayed in negative, even dire terms. This chapter examines some of the probable effects of population aging in Latin America within the ... -
Genetic diversity and evolution of the human leptin locus tetranucleotide repeat
(Hum Genet 110; p. 412-417, 2002)To better understand the evolutionary history of the gene region containing the multifunctional adipose tissue hormone leptin, we genotyped 1,957 individuals from 12 world populations for a highly variable tetranucleo ... -
Genetic polymorphism of CYP1A2 increases the risk of myocardial infarction
(2004)There is growing evidence that DNA damage caused by mutagens found in tobacco smoke may contribute to the development of coronary heart disease (CHD). In order to bind to DNA many mutagens require metabolic activation by ... -
Genetic polymorphism of the adenosine A2A receptor is associated with habitual caffeine consumption
(2007)Background: Caffeine is the most widely consumed stimulant in the world, and individual differences in response to its stimulating effects may explain some of the variability in caffeine consumption within a population. ... -
