Perelleschus Wibmer & O’Brien (Curculionidae: Curculioninae: Derelomini) is revised, including the redescription of P. carludovicae (Günther) from Costa Rica and P. rectirostris Voss from Perú, as well as the addition of six new species: P. evelynae, new species, from Colombia and Panama; P. variabilis, new species, from Ecuador; P. biventralis, new species, from Ecuador; P. splendidus, new spe...

Asthma isa major health problem and their incidence is increasingand represent a recognized cause of morbidity and mortality. Glucocorticoids are the most effective drugs for asthma. Glucocorticoids suppress inflammation by several mechanisms. Its principal action at therapeutic doses is due to trans-repression of activated inflammatory genes, by the recruitment of the enzyme histone desacetyla...

BACKGROUND Since 2004, the uptake of seasonal influenza vaccines in Latin America and the Caribbean has markedly increased. However, vaccine effectiveness (VE) is not routinely measured in the region. We assessed the feasibility of using routine surveillance data collected by sentinel hospitals to estimate influenza VE during 2012 against laboratory-confirmed influenza hospitalizations in Costa...

A five-years long study aiming to describe the basic genetic epidemiology of the dystrophinopathies in Costa Rica recruited 31 patients with clinical symptoms of DMD/BMD at the National Children's Hospital (HNN). This center is the obligate reference hospital of the national health system for genetic diseases, however, the geographic origin of the patients, a low percentage of deletions and a h...

Metallic coloration is one of the signatures of orchid bees of the genus Euglossa, with some species showing variation associated with their geographic range. Euglossa (Alloglossura) gorgonensis Cheesman exhibits color variation, ranging from mainly green specimens in the southern extreme of its range (Pacific slope of Colombia), to noticeably reddish specimens in parts of the northern known li...

Livestock production plays an important role in the economies of Colombia and Costa Rica; livestock production creates direct and indirect jobs and accounts for 32% and 21% of the land used. From an environmental point of view, livestock production contributes to the biological connectivity and forest cover, but it is also a major emitter of greenhouse gases (GHGs). Within the context of the Un...
