The objective of this study was to define a technology package, in order to provide an inventory of the technologies used during the processing of the Peruvian green coffee with specialty coffee qualities to export, supported by a technological management perspective. The methodology relied on a technology package construction, by identifying, describing and quantifying four of its components, based on a systematic literature review, and five professional’s endorsements; each of them knowledgeable of the technologies used in agricultural products processing. Here, semi-structured interviews (Massachusetts Institute of Technology protocol) were used. As a result, a technology package was obtained with 79 generic technologies, 76 of these are involved during the processing activities, which develop physical, sensorial and cultural specialty coffee qualities, valuable for foreign markets....

The objective of this research was to determine the water quality using macroinvertebrates as bioindicators and physical-chemical parameters in the Motil - La Libertad river, by applying the Biological Monitoring Working Party (BMWP) biological index adapted for northern Peru. The procedure was based on the Protocol for sampling, analysis and evaluation of macroinvertebrate benthic fauna in fordable rivers, of the Basque Water Agency of the Basque Country. To carry out the study, 4 sampling points were selected both in spring 2021 and autumn 2022. A total of 1286 specimens were determined, distributed in 21 families and 12 orders, the largest family was Baetidae both in spring and autumn (111 and 549 specimens), for spring the sampling points P-0, P-2 and P-3 obtained poor biological quality "highly polluted waters" and P-1 regular biological quality "contaminated waters"; and for autumn...

Objetivo: revisar la literatura científica sobre los efectos fitoquímicos y farmacológicos de plantas medicinales en el tratamiento de la diabetes mellitus (2013-2023). Materiales y Métodos: se realizó una revisión sistemática en cinco bases de datos (Google Scholar, Pubmed, Scielo, ScienceDirect y Scopus) siguiendo el protocolo PRISMA, analizando 72 estudios. Resultados: Se identificaron metabolitos activos, como alcaloides, flavonoides y terpenos, que podrían modular las vías hiperglucémicas. El 58% de las investigaciones fueron in vivo, el 21% in vitro y el 21% in silico. Estos estudios confirmaron efectos hipoglucemiantes de los compuestos analizados. Conclusión: Se encontró un número significativo de compuestos bioactivos en plantas medicinales con propiedades antidiabéticas. La mayoría de los estudios fueron experimentales (in vivo, in vitro e in silico), lo que sugi...
