Molecules, Vol. 28, Pages 2910: Chemical Composition, Enantiomeric Distribution and Biological Activity of Essential Oil from Morella pubescens (Humb. & amp; Bonpl. ex Willd.) Wilbur
In this study, the chemical composition, enantiomeric distribution, and biological activity of essential oil isolated from the leaves of this species was determined. Hydrodistillation was used to isolate the essential oil (EO). Gas chromatography coupled with mass spectrometry was used to determine the qualitative composition, gas chromatography equipped with a flame ionization detector was used to determine quantitative composition, and gas chromatography on an enantioselective column was used to determine enantiomeric distribution. The broth microdilution method was employed to assess the antibacterial capacity of the es...

Spatial structure and composition of invertebrates in high altitude rivers of the central Andes (Olaroz Salar, Argentina)
This study aimed to examine the spatial variation in sets of micro and macroinvertebrates and to detect how physicochemical and environmental variables affect community structures in high Andean rivers. Six sites were sampled in three rivers of the Argentinian plateau, in altitudes between 3900-4400 masl during the dry season (May-October 2017). The variables that affected the structure of the micro and macroinvertebrate communities were: altitude, conductivity, turbidity, water temperature, hardness, oxygen, and lead. Sites with high levels of arsenic, lead and boron were identified. Assemblages of species common to high ...

Designing databases and using generalized estimating equations for entheseal datasets: An example from the Tiwanaku culture (AD 500 –1100)
AbstractStudying entheseal changes (EC) in human skeletal remains involves questions surrounding how researchers should collect, process, and evaluate these data as there are no set standards. Osteoarcheological research should also be able to answer population-level queries using entheses, such as if group A was moving their body in different ways from group B? Or are there age-related tasks or gendered labors? However, not all entheseal data can be easily evaluated in this fashion. If researchers select one area of the body, they may not be able to discuss population-level differences. In addition, if data are evaluated ...

Alternative Food Networks in Latin America —exploring PGS (Participatory Guarantee Systems) markets and their consumers: a cross-country comparison
AbstractAlternative food networks (AFN) are argued to provide platforms to re-socialize and re-spacealize food, establish and contribute to democratic participation in local food chains, and foster producer –consumer relations and trust. As one of the most recent examples of AFN, Participatory Guarantee Systems (PGS) have gained notable traction in attempting to redefine consumer-producer relations in the organic value chain. The participation of stakeholders, such as consumers, has been a key elemen t theoretically differentiating PGS from other organic verification systems. While research on farmer participation in PGS...

Mycobacterium leprae in Armadillo Tissues from Museum Collections, United States
We examined armadillos from museum collections in the United States using molecular assays to detect leprosy-causing bacilli. We found Mycobacterium leprae bacilli in samples from the United States, Bolivia, and Paraguay; prevalence was 14.8% in nine-banded armadillos. US isolates belonged to subtype 3I-2, suggesting long-term circulation of this genotype.PMID:36823763 | DOI:10.3201/eid2903.221636 (Source: Emerging Infectious Diseases)
