Summary: This study explored the metabolomic profile and cytotoxic activity of Cissus incisa leaves, traditionally used in Mexican traditional medicine to treat certain cancerous illnesses. The results showed that the hexane extract had the strongest inhibitory effect on Hep3B cells, while the chloroform/methanol extract exhibited the highest selectivity on the same cell line. Metabolic pathway analysis and network pharmacology revealed potential targets associated with cellular processes such as apoptosis.

Summary: Phytochemical investigation of the roots of Ampelocissus martini Planch. led to the isolation of five resveratrol oligomers. The isolated compounds showed better RT enzymatic inhibition than the positive control in anti-HIV 1-RT assay. This study also reported the chemical isolation of A. martini for the first time and discussed the chemotaxonomic significance of the isolates.

Summary: A new ceramide, aralioidamide A (1), and five known compounds (2-6) were isolated from the ethanol extract of the stems of Cissus aralioides (Baker) Planch. through repeated column chromatography over silica gel and Sephadex LH-20. The structures of these compounds were determined by extensive spectroscopic (1D and 2D NMR) and spectrometric analysis, as well as comparison with reported data. Aralioidamide A (1) exhibited weak antibacterial activity (MIC=256 mu g/mL) against Bacillus subtilis, Staphylococcus aureus, and Shigella flexneri, and was inactive (MIC>256 mu g/mL) against the tested fungi.

Summary: The relationship between the spotted lanternfly and grape species grown in the United States is unclear. This study found that V. riparia and V. vinifera are favorable hosts for the spotted lanternfly, suggesting that these two grape species may facilitate the invasion and establishment of the pest in new regions.

Summary: The study investigates the wound healing potential of Leea indica, a plant commonly used in traditional medicine in Sri Lanka for treating wounds. Through in vitro cell migration and proangiogenic activity tests, it was found that the dichloromethane extract of L. indica contains a rare phytosterol and several other compounds that enhance cell migration and promote angiogenesis. Compounds 1 and 2 were identified for the first time in L. indica.

Summary: This study investigated the presence of Salmonella enterica and its antimicrobial resistance in paca carcasses sold in the Belen Market of Iquitos-Peru. Various serovars were identified, with a high prevalence of multidrug-resistant strains, particularly in serovar Infantis. The findings suggest a potential risk of foodborne diseases associated with the consumption of wildlife meat in the Amazon region.

Summary: The upper Oligocene San Rafael intrusive complex in southeastern Peru is a case study that investigates the formation of a large granitic pluton associated with a high-grade Sn deposit. Petrological and geochemical analysis suggest that the pluton was formed from multiple injections and mixing of felsic and mafic magmas, influenced by regional geodynamic settings. The pluton acted as a host for Sn mineralization and played a role in the formation of the world-class San Rafael Sn (-Cu) deposit.

Summary: This study reinvestigated the three-dimensionally preserved fruits and seeds of Jatropha tertiara Berry from the early Oligocene of Peru. The results showed that the fossils belong to a new genus, Belenocarpa, and likely have affinities with Euphorbiaceae subfamily Crotonoideae. The well-preserved caruncles on these seeds suggest that insect-plant associations similar to those seen in the present were already present in South America by the Oligocene.

Summary: The analysis of multiple population structures (biodemographic, genetic, and socio-cultural) and their inter-relations contributes to a deeper understanding of population structure and dynamics. The isonymic method is a useful tool for studying population structure by examining surname frequency and distribution. Using this method, a study was able to reconstruct the population structure and migration pattern of the Doctrine of Belen between 1750 and 1813.

Summary: Thermochronological data is crucial for understanding the thermal and exhumation histories of active mountain ranges. However, in the Central Andes, the lack of bedrock outcrops and the presence of volcanic formations have limited the investigation of the exhumation history of the Western Cordillera. This study presents new thermochronological data from the Canete Canyon, indicating the importance of considering burial associated with thick volcanic formations when interpreting data from this region.

Summary: This study investigates the demand for charcoal in the capital of Loreto and the willingness of consumers to pay for reforestation. It finds that the demand for charcoal is a major concern due to its contribution to deforestation, and that there is a willingness among consumers to support reforestation efforts.

Summary: The reevaluation of Andean evolution in southern Peru, northern Bolivia, and northern Chile presents evidence for cyclical orogenic models in which the Andean crust underwent shortening, followed by lithospheric delamination during the Eocene-Oligocene period, leading to renewed uplift of the Andes. The sedimentary fill of the Arequipa rift back-arc basin was controlled by fault systems and crustal structures, which allowed for tectonic inversion and crustal doubling during the Albian and Late Cretaceous-Paleocene periods. The thickening of the Western Cordillera occurred along the inverted graben, driven by high-pressure metamorphism and delamination. Magmatism and asthenospheric upwelling resulted in lithospheric thinning and subsequent surface uplift, accompanied by the development of foreland basins and alkaline potassic magmatism.
