[Adaptation to the reality of Latin America of the NASPGHAN/ESPGHAN 2016 Guidelines on the Diagnosis, Prevention and Treatment of Helicobacter pylori Infection in Pediatrics].

Introduction: The latest joint H. pylori NASPGHAN and ESPGHAN clinical guidelines published in 2016, contain 20 statements that have been questioned in practice regarding their applicability in Latin America (LA); in particular in relation to gastric cancer prevention.

Methods: We conduc ted a critical analysis of the literature, with special emphasis on LA data and established the level of evidence and level of recommendation of the most controversial claims in the Joint Guidelines.

Cryptic Diversity in the Widespread Asian Ant (Hymenoptera: Formicidae) Inferred from Morphological and Genetic Evidence.

The myrmicine species is one of the most widely distributed ants in Asia, but it has rarely been collected in the field. Its distribution range covers South and Southeast Asia, extending approximately 5,000 km from India in the west to Sulawesi in the east. Despite this wide distribution range, has been treated as a single taxonomic species, and no combined morphological or molecular analysis has been conducted to assess whether any intraspecific variation exists.

Clustering of ant communities and indicator species analysis using self-organizing maps.

To understand the complex relationships that exist between ant assemblages and their habitats, we performed a self-organizing map (SOM) analysis to clarify the interactions among ant diversity, spatial distribution, and land use types in Fukuoka City, Japan. A total of 52 species from 12 study sites with nine land use types were collected from 1998 to 2012. A SOM was used to classify the collected data into three clusters based on the similarities between the ant communities.

Molecular phylogeny among local populations of weaver ant Oecophylla smaragdina.

The molecular phylogeny of 24 Oecophylla smaragdina populations and two O. longinoda populations was studied using 647 bp of the mitochondrial cyt b gene. The phylogenetic analysis suggested that O.
