Nowadays, the impacts of climate change are harming many countries around the world. For this reason, the scientific community is interested in improving methods to forecast weather events, so it is possible to avoid people from being injured. One important thing in the development of time series forecasting methods is to consider the set of values over time that facilitates the prediction of future value. In this sense, we propose a new feature vector based on the correlation and autocorrelation functions. These measures reflect how the observations of a time series are related to each other. Then, univariate forecasting is performed using Multilayer Perceptron (MLP) and Long Short-Term Memory (LSTM) deep neural network. Finally, we compared the new model with linear and non-linear models. Reported results exhibit that MLP and LSTM models using the proposed feature vector, they show pro...

The intention of this research was to determine the types of mental schemes and the relation of these in the resolution of problems in the university students of UNHEVAL. The mental schemes were determined by a test of mental schemes that was applied to the students’ sample (69) in individual form and the resolution of problems was demonstrated using instruments to evaluate the cognitive thing, psicomotriz and affective actitudinal. 10 mental schemes were identified: Horizontal, Diagonal, Horizontal Vertical, Horizontal Diagonal, Horizontal Circular, Vertical Diagonal, Diagonal Circular, Horizontal Vertical Diagonal, Horizontal Circular Diagonal, Vague. The mental Horizontal scheme (57%), apparently, has major capacity for the resolution of cognitive problems; the mental Horizontal Vertical scheme (62%) has major capacity for the resolution of problems psicomotrices; and the mental Hor...

The objective of this study was to determine the haematological and serum biochemistry values in a population of woolly monkeys choros (Lagothrix lagotricha)reared in semi-captivity at the Centro de Rescate y Rehabilitación Ikamaperu in Lagunas, Loreto, Peru. Forty primates, 12 males and 28 females, which included juveniles, subadults and adults in apparent good health conditions were sampled. The haematological values were similar, triglyceride and AST values were elevated, and total protein and ALP values were low as compared to other studies in zoos. The age group influenced erythrocyte counts, total protein, total bilirubin, cholesterol and alkaline phosphatase. No sex effect was found on erythrocytes, leukocytes and platelet counts and in serum chemistry values, except for the number of monocytes.

El objetivo de este estudio fue determinar los valores hematológicos y de bioquímica sérica de una población de monos choros (Lagothrix lagotricha) que se encontraban en semicautiverio en el Centro de Rescate y Rehabilitación Ikama peru, en Lagunas, Loreto. Se trabajó con 40 monos, 12 machos y 28 hembras entre juveniles, sub-adultos y adultos en aparente buen estado de salud. Los valores hematológicos fueron similares, los niveles de triglicéridos y de AST estuvieron elevados y los de proteínas totales yALP estuvieron bajos en relación a estudios realizados en zoológicos. El grupo etarioinfluenció los niveles de eritrocitos, proteínas totales, bilirrubina total, colesterol yfosfatasa alcalina; asimismo, no hubo diferencias por efecto del sexo en la serie eritrocítica, conteo de plaquetas y bioquímica sérica, con excepción del número de monocitos.

(1) Background: Somatic mutations may be connected to the exposome, potentially playing a role in breast cancer’s development and clinical outcomes. There needs to be information regarding Latin American women specifically, as they are underrepresented in clinical trials and have limited access to somatic analysis in their countries. This study aims to systematically investigate somatic mutations in breast cancer patients from Latin America to gain a better understanding of tumor biology in the region. (2) Methods: We realize a systematic review of studies on breast cancer in 21 Latin American countries using various databases such as PubMed, Google Scholar, Web of Science, RedAlyc, Dianlet, and Biblioteca Virtual en Salud. Of 392 articles that fit the criteria, 10 studies have clinical data which can be used to create a database containing clinical and genetic information. We compared...

Background: Mutations in STK11 (STK11Mut) and, frequently co-occurring, KEAP1 mutations (KEAP1Mut) are associated with poor survival in metastatic Non-small Cell Lung Cancer (mNSCLC) patients treated with immunotherapy. However, there are limited data regarding the prognostic or predictive significance of these genomic alterations among Hispanics. Methods: This retrospective study analyzed a cohort of Hispanic patients (N = 103) diagnosed with mNSCLC from the US and seven Latin American countries (LATAM) treated with immune checkpoint inhibitors (ICI) alone or in combination as first-line (Cohort A). All cases were treated in routine care between January 2016 and December 2021. The main objectives were to determine the association of mutations in STK11 or KEAP1 in these patients’ tumors with overall (OS) and progression-free survival (PFS), presence of KRAS mutations, tumor mutational ...
