INTRODUCTION: The etiology of several hepatocellular carcinoma (HCC) cases remains largely unknown. Although Fasciola hepatica has been associated with liver fibrosis in Latin America, it has not yet been associated with HCC. This study aimed to determine the existence of specific IgG antibodies against F. hepatica in the serum samples of HCC patients. METHODS: In total, 13 serum samples from 13 HCC patients were screened using Fas2-ELISA. RESULTS: Fas2-ELISA demonstrated negative results in all HCC patients included in this study...

Introduction: Due to its nature, it is very hard to measure tobacco illicit trade in any product. In the case of Latin American countries, there is scant information on the magnitude and characteristics of this trade in the case of cigarettes. The goal of this article is to provide estimates on the evolution of the illicit cigarette trade in five South American countries: Argentina, Brazil, Chile, Colombia and Peru. Methods: Gap analysis estimates for cigarette tax evasion/avoidance (a comparison on the evolution of the difference between registered cigarette sales and measured population consumption) is developed for Argentina, Brazil, Chile, Colombia and Peru...

OBJECTIVES: In the Late Intermediate Period Andes (AD 1100-1450), the proliferation of above-ground sepulchers reconfigured social boundaries within and between communities engaged in protracted conflict. However, the biosocial dimensions of these mortuary practices, and their implications for conflict and alliance formation, remain unexplored. This study examines patterns of phenotypic variation to: (1) evaluate if open sepulchers were organized on the basis of biological relatedness, and (2) explore if sex-specific phenotypic variability conforms to models of postmarital residence...

The South Asian river dolphin ( Platanista gangetica ) is the only extant survivor of the large clade Platanistoidea, having a well-diversified fossil record from the Late Oligocene to the Middle Miocene. Based on a partial skeleton collected from the Chilcatay Formation (Chilcatay Fm; southern coast of Peru), we report here a new squalodelphinid genus and species, Macrosqualodelphis ukupachai . A volcanic ash layer, sampled near the fossil, yielded the 40 Ar/39 Ar age of 18.78 ± 0.08 Ma (Burdigalian, Early Miocene)...

In the Peruvian North Coast (PNC), the number of Plasmodium vivax malaria cases increased steadily from 2007 to 2010 despite a significant decline in the overall number of cases in Peru during the same period. To better understand the transmission dynamics of P. vivax populations in the PNC and the neighboring Ecuadorian Amazon Basin (EAB), we studied the genetic variability and population structure of P. vivax in these areas. One hundred and twenty P. vivax isolates (58 from Piura and 37 from Tumbes in the PNC collected from 2008 to 2010 and 25 from the EAB collected in Pastaza from 2001 to 2004) were assessed by five polymorphic microsatellite markers...

BACKGROUND: Sapoviruses are responsible for sporadic and epidemic acute gastroenteritis worldwide. Sapovirus typing protocols have a success rate as low as 43% and relatively few complete sapovirus genome sequences are available to improve current typing protocols. OBJECTIVE/STUDY DESIGN: To increase the number of complete sapovirus genomes to better understand the molecular epidemiology of human sapovirus and to improve the success rate of current sapovirus typing methods, we used deep metagenomics shotgun sequencing to obtain the complete genomes of 68 sapovirus samples from four different countries across the Americas (Guatemala, Nicaragua, Peru and the US)...

Quinoa is a plant that is cultivated in the Andean highlands across Peru and Bolivia. It is increasingly popular due to its high nutritive value and protein content. In particular, the cultivation of organic quinoa has grown substantially in recent years since it is the most demanded type of quinoa in the foreign market. Nevertheless, despite the interest that quinoa has generated in terms of its nutritional properties, little is known regarding the environmental profile of its production and processing. Therefore, the main objective of this study was to analyze the environmental impacts that are linked to the production and distribution of organic quinoa to the main export destinations through the application of the Life Cycle Assessment (LCA) methodology...

Background: The most traditional scheme for migration among baleen whales comprises yearly migrations between productive waters at high latitude summer feeding grounds and warmer waters at lower latitudes where whales calve and mate, but rarely feed. Evidence indicates, however, that large departures from this scheme exist among populations and individuals. Furthermore, for some populations there is virtually no information on migratory pathways and destinations. Such is the case of Chilean blue whales throughout the Eastern South Pacific; hence, the goal of this study was to assess its migratory behavior...
