OBJECTIVE: The absence of an universal classification for hyperthyroidisms (HT), give rise to inadequate interpretation of series and trials, and prevents decision making. We offer a tentative classification based on gammagrafic and functional findings. MATERIAL AND METHODS: Clinical records from patients who underwent thyroidectomy in our Department since 1967 to 1997 were reviewed. Those with functional measurements of hyperthyroidism were considered. All were managed according to the same preestablished guidelines. RESULTS: HT was the surgical indication in 694 (27,1%) of the 2559 thyroidectomies. Based on gammagraphic studies, we classified HTs in: Parenchymatous Increased-Uptake, which could be Diffuse, Diffuse with Cold Nodules or Diffuse with at least one Nodule, and Nodular Increased-Uptake (Autonomous Functioning Thyroid Nodes [AFTN]), divided into Solitary AFTN or Toxic Adenoma...

This study describes the axiological model of the technological package as a pre-patentable foundation of innovation, designed to articulate the value dimensions underpinning validation, transfer, and potential impact on preventive health. A descriptive, non-experimental study with a qualitative–analytical approach was conducted through structured documentary review and hermeneutic content analysis. The results present a systemic model that integrates ethical, technical, and social principles, structuring the innovation process from need identification to product commercialization and maintenance. This framework demonstrates that axiological coherence provides the technical robustness, sustainability, and social relevance required for responsible biotechnological innovation. The study concludes that the axiological foundation enables the transformation of scientific knowledge into pre-...

A neural network is a mathematical model that is able to perform a task automatically or semi-automatically after learning the human knowledge that we provided. Moreover, a Convolutional Neural Network (CNN) is a type of sophisticated neural network that has shown to efficiently learn tasks related to the area of image analysis (among other areas). One example of these tasks is image segmentation, which aims to find regions or separable objects within an image. A more specific type of segmentation called semantic segmentation, makes sure that each region has a semantic meaning by giving it a label or class. Since neural networks can automate the task of semantic segmentation of images, they have been very useful for the medical area, applying them to the segmentation of organs or abnormalities (tumors). Therefore, this thesis project seeks to address the task of semantic segmentation of ...

Maca is nutritious, energetic and functional food. As a defense mechanism, its secondary metabolites react to biotic and abiotic stress, during pre-harvest, harvest and traditional post-harvest drying. The aim of this review is to evaluate and provide relevant scientific information about bioactives, biochemistry and biological activity of the maca (Lepidium meyenii Walpers or Lepidium peruvianum Chacón) related to health and reassess its functional food condition. A search of four electronic databases and information required from the authors was used for this review. There is a lack of in vivo and clinical research with more representative sample sizes and more consistent methodologies. Therefore, glucosinolates, phenolic compounds, phytosterols, macaenes, macamides, macahidantoins, meyeniins, alkaloids and others formed during the productive cycle of maca act synergistically to preve...

The purpose of this research is to analyse the landscape and archaeoastronomical heritage of Ñaña, Lurigancho-Chosica, which subsists in the interstices of the contemporary urban periphery of Metropolitan Lima. Despite the state’s neglect and unregulated urban growth in its surroundings, it holds many unexploited attributes. The Union-Ñaña archaeological zone was inhabited since pre-Hispanic times by specialists in the observation of astronomical phenomena called yañac, who were linked to the cult of the snow peak Pariacaca. The latter was the most important apu from the Central Andes of Peru, according to the mythical 'Manuscript of Huarochirí' from the 16th century. Thus, the study of the relationship between landscape and astronomical alignments (a key aspect of the Andean worldview) is a crucial component of the following study, which also has the goal of expanding the unders...
