Juan Valdelamar-Villegas, Jesus Olivero-Verbel
Donax denticulatus is a key mollusk for the ecology of sandy beaches, serving as a controller of organic matter, microorganisms, and as bioindicator of heavy metals pollution. The goal of this study was to characterize some ecological aspects of D. denticulatus and its relationship with the content of heavy metals in their tissue, in three beaches of the Caribbean coast of Colombia. The results showed the study populations were different in terms of morphological characteristics and density (Berrugas-Sucre < Cartagena-Bolívar < Riohacha-Guajira), but not in sexual proportion; although density was clearly related to beach occupancy by tourists...

Obesity is becoming an epidemic in Latin American countries. Genetic analyses of endophenotypes for obesity, such as body mass index (BMI), are quite useful for research. In this study, we analysed two functional polymorphisms in the dopamine receptor 4 (DRD4) and dopamine transporter (SLC6A3) genes. A sample of 232 Colombian young subjects were recruited and evaluated for BMI. Two functional polymorphisms in the DRD4 and SLC6A3 and genes were genotyped by PCR and electrophoresis. A significant association was found between BMI and the polymorphisms in DRD4 and SLC6A3 genes...

Leprosy is a chronic infectious disease with a broad spectrum of manifestations. Delays in attaining correct diagnosis permit progressive peripheral nerve damage that can produce irreversible disabilities. Tests detecting antigen-specific antibodies can aid the diagnostic process and potentially detect patients earlier. Reported tests have lacked optimal sensitivity and specificity; however, the need to develop new tests to aid early diagnosis still remains. In this study, we determined the sensitivity, specificity, positive predictive value, and negative predictive value of enzyme-linked immunosorbent assay (ELISA) using natural octyl disaccharide-leprosy IDRI diagnostic (NDO-LID)...

This study evaluated the influence of environmental heterogeneity on Anopheles darlingi genetic and morphometric traits at a microgeographic level. Specimens of An. darlingi collected from multiple municipalities in the Colombian malaria endemic region Urabá-Bajo Cauca and Alto Sinú (UCS) were analyzed using 13 microsatellite loci. Spatial genetic structure, population variation and wing geometric morphometric analyses were performed. Microsatellite results showed low genetic differentiation and high gene flow among populations; four highly admixed subpopulations were detected with no particular association to the municipalities...

Renal involvement in Systemic Lupus Erythematous (SLE) patients is one of the leading causes of morbidity and a significant contributor to mortality. It's estimated that nearly 50% of SLE individuals develop kidney disease in the first year of the diagnosis. Class IV lupus nephritis (LN-IV) is the class of lupus nephritis most common in Colombian patients with SLE. Altered miRNAs expression levels have been reported in human autoimmune diseases including lupus. Variations in the expression pattern of peripheral blood circulating miRNAs specific for this class of lupus nephritis could be correlated with the pathophysiological status of this group of individuals...

The present work is part of a process to create a Catalogue of the Freshwater Fishes of Colombia and consisted in the depuration and updating of the taxonomic and geographic components of the checklist of the freshwater fishes of Colombia. An exhaustive revision of the 1435 species recorded in 2008 was necessary to: 1. Add new species described since 2009 and species originally described from Colombia but inadvertently omitted in 2008; 2. Add new records of already described species; 3. Delete species whose presence in Colombia was not supported by voucher specimens in ichthyological collections; and 4...

Rapid Hispanic growth has been a major source of increasing ethnoracial diversity in the United States. However, diversity within the Hispanic population is frequently obscured by the tendency to lump all Latinos together. Our study examines Hispanic diversity at the local level, drawing insights from the Mexican dominance, Caribbean-centric settlement, spatial assimilation, and economic opportunity perspectives. Measures of the magnitude and structure of Hispanic origin-group diversity during the 1990-2010 period are constructed for 363 metropolitan areas based on each area's shares of Mexicans, Puerto Ricans, Cubans, Dominicans, Salvadorans, Guatemalans, Colombians, and 'others'...

The transatlantic slave trade was the largest forced migration in world history. However, the origins of the enslaved Africans and their admixture dynamics remain unclear. To investigate the demographic history of African-descendant Marron populations, we generated genome-wide data (4.3 million markers) from 107 individuals from three African-descendant populations in South America, as well as 124 individuals from six west African populations. Throughout the Americas, thousands of enslaved Africans managed to escape captivity and establish lasting communities, such as the Noir Marron...

Background Information regarding urinary biomarkers in Mestizo and Afro-Latin-American patients is very limited. We investigated whether levels of urinary neutrophil gelatinase-associated lipocalin (NGAL), and monocyte chemoattractant protein 1 (MCP-1) are good biomarkers to differentiate patients with lupus nephritis among Latin-American systemic lupus erythematosus (SLE) patients. Methods SLE patients meeting the revised American College of Rheumatology classification criteria for SLE were recruited. Urinary levels of NGAL and MCP-1 were measured using a commercial ELISA kit...

A new sphyrapodid tanaidacean, Sphyrapus caribensis sp. nov. is described and a new record of Kudinopasternakia siegi is reported for the Colombian Caribbean based on samples collected during cruises in 2014-2015. The new species appears to be most closely related to the northeast Atlantic species, Sphyrapus malleolus. Sphyrapus caribensis can be distinguished from Sphyrapus malleolus by a combination of characters, including the maxillipedal basis without long distal seta, the number of setae on the distoventral margin of pereopods 1 and 2, and the number of plumose seta on the pleopod basis...
