Cognitive efforts tests, such as the Test of Memory Malingering (TOMM; Tombaugh, 1997), are widely used internationally, yet there is a dearth of research that has assessed the utility of these measures in different cultures, countries, and languages. This study evaluated the specificity of the TOMM Trial 2 among a sample of 3,590 Spanish-speaking adults residing in 8 Latin American countries (Argentina, Bolivia, Chile, Colombia, Mexico, Paraguay, Peru, and Puerto Rico). Trial 2 TOMM scores were negatively associated with participants' age and positively associated with level of education...

Cordyceps sensu lato is a genus of arthropod-pathogenic fungi, which have been used traditionally as medicinal in Asia. Within the genus, Ophiocordyceps sinensis is the most coveted and expensive species in China. Nevertheless, harvesting wild specimens has become a challenge given that natural populations of the fungus are decreasing and because large-scale culture of it has not yet been achieved. The worldwide demand for products derived from cultivable fungal species with medicinal properties has increased recently...

Johanna B Fine, Katherine Mayall, Lilian Sepúlveda
International and regional human rights norms have evolved significantly to recognize that the denial of abortion care in a range of circumstances violates women's and girls' fundamental human rights. These increasingly progressive standards have played a critical role in transforming national-level abortion laws by both influencing domestic high court decisions on abortion and serving as a critical resource in advancing law and policy reform. Courts in countries such as Argentina, Bolivia, Brazil, Colombia, and Nepal have directly incorporated these standards into groundbreaking cases liberalizing abortion laws and increasing women's access to safe abortion services, demonstrating the influence of these human rights standards in advancing women's reproductive freedom...

BACKGROUND: Leptospirosis is caused by pathogenic spirochetes of the genus Leptospira spp. This zoonotic disease is distributed globally and affects domestic animals, including cattle. Leptospira interrogans serogroup Sejroe serovar Hardjo and Leptospira borgpetersenii serogroup Sejroe serovar Hardjo remain important species associated with this reproductive disease in livestock production. Previous studies on Brazilian livestock have reported that L. interrogans serovar Hardjo is the most prevalent leptospiral agent in this country and is related to clinical signs of leptospirosis, which lead to economic losses in production...

In South America Trypanosoma evansi has been determined by molecular methods in cattle from Bolivia, Brazil, Colombia and Peru, reason for which the presence of this parasite is not excluded in Venezuelan livestock. Therefore, the aim of this study was to perform parasitological and molecular diagnosis of cattle trypanosomosis in small livestock units from two regions in this country. The parasitological diagnosis was carried out by MHCT and the molecular by PCR using genus-specific ITS1 primers that differentiate T...

The large spiny mouse Neacomys spinosus (Thomas, 1882) has been considered the widest ranging species of the genus, occurring in southern Colombia, eastern Peru, western Brazil and northern Bolivia. The morphological variation between subspecies and populations of N. spinosus has been noted; nonetheless, this variation has not been assessed in a morphological or molecular context. Here, we present a taxonomic revision of Neacomys spinosus s.l. using qualitative and quantitative morphological analyses. These analyses were complemented with molecular analysis to reconstruct the phylogenetic relationships among species of Neacomys, based on sequences of the cytochrome b gene...

Thiago V V Costa, José Fernando Pacheco, Luís Fábio Silveira
The Curl-crested Aracari Pteroglossus beauharnaesii Wagler, 1832 is one of the most remarkable species in the family Ramphastidae. Among other distinctive plumage traits, its modified curly, shiny black crown feathers are unique in the family and are modified to an extent not found in any other living bird species (Brush 1967; Short & Horne 2002). The crown feathers, along with the distinct white throat, were considered sufficient justification in the past to include the species in the monotypic genus Beauharnaisius Bonaparte; however, molecular studies have shown that it is embedded within the genus Pteroglossus Illiger, sister to P...
