Wildlife lead exposure is an increasing conservation threat that is being widely investigated. However, for some areas of the world (e.g., South America) and certain species, research on this subject is still scarce or only local information is available. We analyzed the extent and intensity of lead exposure for a widely distributed threatened species, the Andean Condor (Vultur gryphus). We conducted the study at two different scales: 1) sampling of birds received for rehabilitation or necropsy in Argentina, and 2) bibliographic review and extensive survey considering exposure event for the species' distribution in South America...

Tapeworms Taenia solium and Taenia saginata are the causative agents of taeniasis/cysticercosis. These are diseases with high medical and veterinary importance due to their impact on public health and rural economy in tropical countries. The re-emergence of T. solium as a result of human migration, the economic burden affecting livestock industry, and the large variability of symptoms in several human cysticercosis, encourage studies on genetic diversity, and the identification of these parasites with molecular phylogenetic tools...

For the last three-decade cardiovascular disease have been the principal causes of death in most Latin American countries. Their importance has been rising, as in developed countries; such as United State, the mortality rate for CV disease declined in LA rises as in the other developing countries.Cardiovascular risk factors epidemiological studies from LA tend to be limited, and with restrictions on the methodology for sampling and interpretation of results; making most of the studies little comparable each other;on the other hand, population characteristics from country to country and inside each country are so different in ethnicity, habits, socio-economic status which make difficult to integrate and compare results as a whole...

Chronic physical and mental health conditions account for a rising proportion of morbidity, mortality, and disability in the Americas region. Household food insecurity (HFI) has been linked to chronic disease in US and Canadian women but it is uncertain if the same is true for low- and middle-income Latin American countries in epidemiologic transition. We conducted a survey to investigate the association of HFI with the physical and mental health of 794 women with children living in low-income Quito, Ecuador, neighborhoods...

Several Latin American countries are implementing a suite of so-called "postneoliberal" social and political economic policies to counter neoliberal models that emerged in the 1980s. This article considers the influence of postneoliberalism on public health discourses, policies, institutions, and practices in Bolivia, Ecuador, and Venezuela. Social medicine and neoliberal public health models are antecedents of postneoliberal public health care models. Postneoliberal public health governance models neither fully incorporate social medicine nor completely reject neoliberal models...

Squids are active and opportunistic predators that feed on a wide range of prey. Their active movements in the water column and their voracity promote a high consumption of food. In the pelagic environment off Ecuador, marine pollution is characterized by plastic debris with a mainland origin, including plastics trash of fishing gears. The objective of this work was to describe the presence of plastic remains in the stomach contents of Dosidicus gigas caught off the coast of Ecuador. Results demonstrated that 12% of the stomachs contained plastic remains...

BIRM is an anticancer herbal formulation from Ecuador. Previous study established its antitumor and antimetastatic activity against prostate cancer models. The activity of BIRM against human prostate cancer (PCa) cells was investigated to uncover its mechanism of antitumor activity. In androgen receptor (AR)-expressing PCa cells BIRM was 2.5-fold (250%) more cytotoxic in presence of androgen (DHT) compared to cells grown in the absence of DHT. In AR-positive cells (LAPC-4 and LNCaP) BIRM caused a dose and time-dependent down-regulation of AR and increased apoptosis...

Over the past decade, the Sea Catfish (Ariidae) genus Cathorops has been the focus of a major taxonomic review, which has resulted in the revalidation of five synonymized nominal species, and the recognition of seven new species. With 21 valid species, Cathorops is currently the most species-rich genus of Ariidae in the New World. The principal lacuna in the taxonomic knowledge of genus species is the uncertain status of Arius festae Boulenger, 1898, described from Naranjal, in the Guayas River basin of Ecuador...

Dasypus kappleri is the largest species of the genus Dasypus and is restricted to the Amazonian rainforest biome. Over the last century, related taxa have been described and synonymized without comprehensive analyses, and the current classification involving two subspecies, Dasypus k. kappleri and Dasypus k. pastasae, has never been revised. The aim of this work is to clarify the taxonomy of Dasypus kappleri through integrative morphological and morphometric analyses. We examined 70 specimens housed in scientific collections as well as photographs of the type specimens of five nominal taxa...

Climate change is a global concern but little is known about its potential health effects in workers from non-industrialized countries. Ecuadorian workers from the coast (hot environments) and Andean region (elevated UV radiation) might be at particular risk of such effects. In the Andean region, measurements of UV index show maximum levels exceeding 11, a level considered being extreme according to the WHO. Also, an increased incidence of skin cancer was reported the last decennium, this being the second most common cancer type in men and women...
