ABSTRACT
Machu Picchu originally functioned as a palace within the estate of the Inca emperor Pachacuti between ~1420 and 1532 CE. Before this study, little was known about the people who lived and died there, where they came from or how they were related to the inhabitants of the Inca capital of Cusco. We generated genome-wide data for 34 individuals buried at Machu Picchu who are believed to have been retainers or attendants assigned to serve the Inca royal family, as well as 34 individuals from Cusco for comparative purposes. When the ancient DNA results are contextualized using historical and archaeological data, we conclude that the retainer population at Machu Picchu was highly heterogeneous with individuals exhibiting genetic ancestries associated with groups from throughout the Inca Empire and Amazonia. The results suggest a diverse retainer community at Machu Picchu in which people of different genetic backgrounds lived, reproduced, and were interred together.
ABSTRACT
There are many unanswered questions about the population history of the Central and South Central Andes, particularly regarding the impact of large-scale societies, such as the Moche, Wari, Tiwanaku, and Inca. We assembled genome-wide data on 89 individuals dating from â¼9,000-500 years ago (BP), with a particular focus on the period of the rise and fall of state societies. Today's genetic structure began to develop by 5,800 BP, followed by bi-directional gene flow between the North and South Highlands, and between the Highlands and Coast. We detect minimal admixture among neighboring groups between â¼2,000-500 BP, although we do detect cosmopolitanism (people of diverse ancestries living side-by-side) in the heartlands of the Tiwanaku and Inca polities. We also highlight cases of long-range mobility connecting the Andes to Argentina and the Northwest Andes to the Amazon Basin. VIDEO ABSTRACT.

Here, we report a draft genome sequence of Aeromonas veronii strain CTe-01 (4.5 Mb), a hemolytic, heavy metal-resistant bacterium isolated from a wastewater treatment plant located at Cachiche, Ica, Peru. These characteristics could be used for bioremediation of contaminated environments.
ABSTRACT
Es bien conocido que la malnutrición energético-proteica (MEP) es una situación muy frecuente entre lospacientes hospitalizazdos, tanto médicos como quirúrgicos. Los pacientes con enfermedades gastrointestinales y hépaticas constituyen un colectivo en el que el déficit nutricional es especialmente frecuente, como consecuencia de que su enfermedad de base afecta a órganos involucrados en la incorporación y el metablismo de los nutrientes. La frecuencia de MEP en una sala de gastroenterologia de un hospital europeo de tercer nivel se ha cifrado en alrededor de 70 porciento de los enfermos, delos que mas de la mitad tiene algún grado de desnutrición...
