Genetic variation of the Y chromosome in Chibcha-Speaking amerindians of Costa Rica and Panama
(Human Biology 77(1): 71-91, 2005)Genetic variation of the Y chromosome in five Chibchan tribes (Bribri, Cabecar, Guaymi, Huetar, and Teribe) of Costa Rica and Panama was analyzed using six microsatellite loci (DYS 19, DYS389A, DYS389B, DYS390, DYS391, and ... -
Genetic, dietary, and other lifestyle determinants of serum homocysteine levels in young adults in Costa Rica
(2005)Objective: Elevated serum total homocysteine (tHcy) is considered an independent risk factor for cardiovascular disease. The objective of this study was to develop the first-ever information on the prevalence of ... -
Genomic context of the two integrons of ST-111 Pseudomonas aeruginosa AG1: A VIM-2-carrying old-acquaintance and a novel IMP-18-carrying integron
(2021)Pseudomonas aeruginosa is an opportunist and versatile organism responsible for infections mainly in immunocompromised hosts. This pathogen has high intrinsic resistance to most antimicrobials. P. aeruginosa AG1 (PaeAG1) ... -
Geographical variability of the venoms of four populations of Bothrops asper from Panama: Toxicological analysis and neutralization by a polyvalent antivenom
(2017-06)Bothrops asper is the medically most important venomous snake in Central America. In Panama, the country having the highest incidence of snakebites in Latin America, B. asper is widely distributed throughout the country ... -
Global genetic diversity of Aedes aegypti
(2016-11)Mosquitoes, especially Aedes aegypti, are becoming important models for studying invasion biology. We characterized genetic variation at 12 microsatellite loci in 79 populations of Ae. aegypti from 30 countries in six ... -
Group-II phospholipase A2 enzymes
(2015-05)Phospholipase A2 are esterolytic enzymes that catalyze the hydrolysis of 1,2-diacyl-3-sn-glycerophospholipids at the C2 position, resulting in the formation of lysophospholipids and free fatty acid. They constitute one of ... -
