Authors: García-García Paola Monserrat , Galindo-Alcántara Adalberto , Ruiz-Acosta Silvia del Carmen
Published: March 2024

La pectina obtenida de residuos agroindustriales es una importante fuente de abastecimiento, no solo porque los residuos tienen una importante cantidad del biopolímero, sino que también es una forma de aprovechar los desechos biológicos de las agroindustrias que generalmente se convierten en problemas de contaminación al ambiente o que su disposición final bajo un adecuado tratamiento incrementa los costos de producción. Debido a sus propiedades espesantes, gelificantes, estabilizantes y biodegradabilidad puede emplearse a nivel agrícola, en la industria alimentaria, cosmética y farmacéutica. Para su aprovechamiento existe una variedad de procedimientos metodológicos extractivos y variantes dentro de cada procedimiento. El objetivo de esta revisión fue recabar y analizar información sobre los métodos industriales de extracción de esta materia prima altamente demandada, centrándose sobre la fase extractiva y parámetros de mayor influencia en el rendimiento y la calidad de la extracción de pectina en frutos. Los resultados indican que el método químico de hidrólisis ácida sin asistencia fue el más aplicado para la extracción de pectina utilizando como solución extractiva principalmente el ácido clorhídrico, aplicando una temperatura de 90 °C y pH entre 1 y 2.2, así como un tiempo de 60 min. El proceso extractivo es fuertemente influido por los valores y las combinaciones de valores de la solución extractante utilizada, la temperatura a la que se realiza la hidrólisis, el pH con el que se realiza el proceso y el tiempo de duración de la extracción. Estos factores determinan la calidad y el rendimiento de la pectina obtenida.

Published: March 2024

Pese a la liberalización de la agricultura durante las últimas décadas, México se encuentra cerca de la autosuficiencia en el caso del frijol. El comportamiento del mercado de este grano está determinado principalmente por factores internos que afectan tanto la demanda como la oferta. En este contexto, el objetivo del presente artículo es analizar el movimiento de los precios de frijol negro bola en Zacatecas y el frijol pinto en Chihuahua, y el movimiento de precios para las mismas variedades en la Ciudad de México; para ello, se emplearon precios mensuales del periodo agosto 2005 – junio 2022. El análisis se realizó con métodos econométricos que determinan la transmisión horizontal de precios. Los resultados indican la presencia de cointegración para los precios de frijol negro bola, así como una causalidad en ambas direcciones. También se encontró causalidad en ambas direcciones para el frijol pinto, aunque los precios no están cointegrados.

El estudio de la estructura y diversidad de los ecosistemas forestales es fundamental para comprender el funcionamiento y dinámica de los bosques. Se describió la estructura y diversidad de especies leñosas en diferentes tipos de curso de agua a lo largo del río Santa Catarina en Nuevo León, México. Se identificaron tres condiciones hidrológicas: permanente (I ), semipermanente (II ) y temporal (III ). En cada condición se establecieron 14 sitios rectangulares de 1 000 m2, todas las especies de cada sitio fueron identificadas. Se midió el diámetro de la copa de cada individuo, el Índice de Valor de Importancia (IVI) de condición. La riqueza y diversidad de especies fue calculada con los índices de Margalef (DMg) y Shannon-Wiener ( H'). Además, se determinó la similitud entre condiciones con el índice de Sorensen (Is). Se identificaron 32 especies, 29 géneros y 16 familias. La condición I registró mayor riqueza específica y diversidad con 28 especies y un valor de diversidad H' = 2.41 ± 0.710, en donde Salix nigra presentó el mayorIVI. La condición II presentó la mayor riqueza de Margalef con un valor DMg de 1.77 ± 0.22. En la condición III Leucaena leucocephala fue la especie más importante. La similitud entre condiciones fue mayor al 50%. Los resultados demuestran la variación estructural de la vegetación en diferentes regímenes hidrológicos, lo cual constituye una base sólida para futuras investigaciones sobre el desarrollo de la vegetación asociada al río Santa Catarina, y otras áreas riparias del norte de México.

El hongo Rhizopus stolonifer causa pudrición de frutas y verduras, por lo que es importante la búsqueda de alternativas de control biológico. El objetivo fue realizar antagonismo y evaluar la actividad antifúngica de H. coffeata contra R. stolonifer. Se evaluó el porcentaje de reducción del crecimiento micelial (PRCM) y el tipo de antagonismo de R. stolonifer al crecerlo junto con las cepas antagonistas y se evaluó la actividad antifúngica del caldo de cultivo de H. coffeata. El PRCM fue mayor para H. coffeata y Daldinia sp., presentaron antagonismo de clase 1, inhibición por contacto, ya que el micelio de H. coffeata enrolló las hifas de R. stolonifer. Los tres caldos de cultivo de H. coffeata presentaron efecto sobre el crecimiento de R. stolonifer, pero, fue más evidente en el cocultivo, por lo que mediante este sistema se puede obtener moléculas para utilizarse en el bio-control de R. stolonifer.

Se estimó la exactitud de la predicción (EP) de valores genómicos estimados (GEBV) para variables de peso vivo de ganado Charolais utilizando dos métodos de validación cruzada. Se ajustó un modelo BLUP y diferentes métodos de predicción genómica (PG) Genomic-based best linear unbiased prediction (GBLUP), Bayes C (BC) y Single-step Bayesian regression (SSBR). La EP fue comparada mediante grupos de validación (GV) formados aleatoriamente y mediante GC. Los resultados mostraron que los tres métodos de PG proporcionaron exactitudes de predicción similares entre los
GV
pero no exactitudes de predicción superiores a BLUP. La exactitud de predicción de GBLUP y BLUP fue 0.35 y 0.37 para PN, y de 0.30 y 0.41 para PD, respectivamente. Los resultados muestran bajas exactitudes de PG bajo los escenarios evaluados; por lo que para su correcta implementación es necesario incrementar el número de animales y usar valorees genéticos desregresados como variables de respuesta.

Published: March 2024

El uso de nanopartículas (NPs) en la agricultura presenta diversas aplicaciones, entre las cuales se destaca el potencial para aumentar las tasas de producción y mejorar los valores nutricionales de las plantas. Este estudio se centra en la aplicación foliar de nanopartículas de óxido de zinc (NPs-ZnO) en plantas de Lactuca sativa L. var. longifolia producidas en un sistema hidropónico con la técnica de película de nutrientes (NFT). La investigación se llevó a cabo durante el ciclo otoño-invierno 2022-2023. El objetivo principal de la investigación fue evaluar el impacto de las NPs-ZnO sobre el rendimiento, compuestos bioactivos y actividad enzimática en lechuga. Los tratamientos evaluados fueron: tratamiento control (0) y cuatro dosis equidistantes de 10, 20, 30 y 40 mg L-1 de nanopartículas; el diseño utilizado fue completamente al azar. Los resultados revelan que la concentración de zinc (Zn2+) en las plantas aumenta significativamente con la aplicación de NPs-ZnO, lo que conlleva a mayor producción de metabolitos beneficiosos para el cultivo. Es destacable que la concentración de 40 mg L-1 de NPs-ZnO haya mostrado mejoras significativas con respecto al tratamiento control en todas las variables evaluadas; peso fresco, materia seca, contenido de zinc, clorofila total, carotenoides totales, fenoles totales, capacidad antioxidante, flavonoides totales, vitamina C, catalasa y peroxidasa, sugiriendo que esta dosis específica podría ser óptima para obtener máximos beneficios. Por lo tanto, la aplicación foliar de NPs ZnO es una manera práctica de enriquecer las plantas de lechuga y mitigar las deficiencias de este micronutriente en la población.

En condiciones controladas, se ha demostrado que la aplicación de sustancias húmicas (SH) favorece el crecimiento y el desarrollo de las plantas. Sin embargo, la evidencia científica en condiciones de campo y cultivo de temporal ha sido escasamente documentada. El objetivo en esta investigación, realizada en el IPN-CIIDIR Oaxaca en el año 2019, fue caracterizar los ácidos húmicos (AH) extraídos de vermicomposta de residuos sólidos urbanos empleando técnicas químicas y espectroscópicas, y evaluar el efecto de su aplicación vía radical en la etapa reproductiva, con riego y déficit hídrico inducido, en tres selecciones de maíz (Zea mays L.) nativas de tres regiones de Oaxaca, México, cultivadas en condiciones de campo. Los AH promovieron mayores valores en altura de la planta, diámetro del tallo y producción de biomasa radical y aérea, en presencia de riego y con déficit hídrico inducido. El contenido relativo de agua y de prolina también fue estimulado, así como el contenido de clorofilas a, b y (a+b). Los efectos negativos causados por un estrés hídrico inducido fueron atenuados por la aplicación de los AH. Los AH procedentes de vermicomposta de residuos sólidos urbanos estimularon los parámetros de crecimiento en la fase reproductiva e indujeron protección antiestrés cuando se limitó el uso del riego.

Authors: Ortiz-Garcia William Ricardo , Navarrete-Villarraga Zulma Carolina
Published: March 2024

This paper reports the results of a qualitative action research study conducted with children from a private Colombian institution. This study aimed to analyze the learners’ cognitive and knowledge outcomes measured according to the revised Bloom’s taxonomy once content and language integrated learning was implemented. Data were gathered through an interview with the learners’ parents, observation, and video recordings. Results give evidence that learners develop different processes simultaneously, classified by the mentioned taxonomy. This taxonomy is a helpful approach for English learners since it allows them to perform cognitive and knowledge processes without following rigid systematic learning. As a conclusion, this implementation with children allowed participants to develop cognitive processes with greater emphasis in levels 3 and 4 (apply and analyze), whereas level 2 (understand) was developed as part of the process. Meanwhile, the factual and conceptual knowledge dimensions were strengthened. Finally, procedural, and metacognitive knowledge is developed through the implementation itself.

Published: March 2024

Introduction: The assessment of disease activity is crucial for effectively managing chronic diseases like spondyloarthritis (SpA). Establishing the relationship between disease activity, demographic, and clinical factors is essential for better disease management. This study aimed to delve into the demographic and clinical characteristics of patients at Dr. Soetomo General Academic Hospital, a tertiary hospital in Surabaya, Indonesia, contributing to a comprehensive understanding of SpA occurrences in Surabaya.Methods: Data were obtained from 38 SpA patients’ data classified using ASAS 2009 criteria at Dr. Soetomo General Academic Hospital, excluding individuals with SLE, gout, RA, and septic arthritis. Disease activity was measured using ASDAS-CRP. Association analysis between disease activity, clinical parameters, and demographics was conducted using Mann-Withney U test and Spearman correlation test.Results: Results indicated a male-to-female ratio of 8:30, with patients having a median age of 48 (95% CI: 41-53) and most of the patients had a senior high school education (42.11%). The patients exhibited a mean BMI of 25.19 ± 3.77, a median disease duration of 8.5 (95% CI: 5-10) years, and a median CRP value of 0.2 (95% CI: 0.1-0.5) mg/dL. The majority displayed moderate disease activity, with a median ASDAS-CRP score of 2 (95% CI: 1.5-2.7). Interestingly, no significant correlation was found between disease activity using ASDAS-CRP and the demographic or clinical parameters studied.Conclusion: Disease activities were found not to have correlations with the demography and clinical parameters of patients with SpA from Dr. Soetomo General Academic Hospital in Surabaya, Indonesia. This emphasizes the necessity for further research to comprehend the intricate relationship between disease activity and diverse influencing factors.

Systemic lupus erythematosus (SLE) has diverse clinical presentations, including lupus nephritis (LN), if LN manifest the mortality & morbidity will be elevated. The majority of SLE cases found in females, especially during puberty and childbearing age. A comprehensive understanding of the epidemiology, classification, diagnosis, and management of LN is essential for medical practitioners. Initially, the diagnostic process requires clinical examinations to find clinical manifestations. This process then followed by laboratory assessments to diagnose SLE and identify any indication related to kidney damage, commonly proteinuria. Other findings such as haematuria and leukocyturia may also present. Antinuclear antibodies (ANA) test and anti-dsDNA serves as primary diagnostic tool. In addition, kidney biopsy is the gold standard for LN due to its ability to confirm and measure the stadium for treatment guide. The therapy is specifically based on clinical and biopsy findings, categorized by World Health Organization (WHO) into five classes, namely normal, mesangial, focal and segmental proliferative, diffuse proliferative, and membranous. Accurate diagnosis in the initial stage and suitable therapy is crucial to significantly improve the prognosis of LN. In this review, we address some clinical manifestations related to LN and standardised diagnostic assessment tools, with an ultimate goal to improve the outcome of patients with lupus through an individual-specific management.

Published: March 2024

Congestion not only represents a cardinal sign of heart failure but is also now recognized as the primary cause for hospital admissions, rehospitalizations, and mortality among patients with acute heart failure. Congestion can manifest through various heart failure phenotypes in acute settings: volume overload, volume redistribution, or both. Recognizing the congestion phenotype is paramount, as it implies different therapeutic strategies for decongestion. Complete decongestion is hardly achieved among patients with acute heart failure, as more than half still have residual congestion at discharge. Residual congestion is one of the strongest predictors of future cardiovascular events and poor outcomes. Through this review, we try to provide a better understanding of the congestion phenomenon among patients with acute heart failure by highlighting insights into the pathophysiology mechanisms behind congestion and new diagnostic and management tools to achieve and maintain efficient decongestion.

Abstract. Case study on types of ecosystem materials of science learning tasks during the COVID-19 pandemic (for class v students at SSDN Pajang 4 surakarta). This research is included in the type of qualitative research with descriptive qualitative methods and case study. The subjects of this study were students, teachers, and parents. Validity testing was used source triangulation and technique triangulation.The results of the study concluded that the type of science learning task on ecosystem materials was observing tasks, namely reading materials to obtain information about ecosystem materials. Communication tasks include reading the food chain and reporting assignments in writing. The task of grouping was to find differences and similarities between symbiosis. This type of predicting task asked students to predict events that will occur if a component changes in the food chain. Constraints encountered by students are student discipline problems when working, facilities constraints, some students still use parental devices, and finally the lack of understanding of ecosystem material. The average student assignment score is 82.5, with 63% getting a score above the KKM. Keywords: Types of assignments, Sciences, Elementary School

Project to Strengthen Pancasila Student Profile (P5) is very important to improve the character of students, especially independent learning. The novelty of this research is that it focuses on the factors that influence learning independence in the Pancasila Student Profile Strengthening Project (P5). This research uses descriptive qualitative methods with a qualitative approach. Factors that affect the learning independence of students in class are divided into two, namely internal factors and external factors. Internal factors include the ability of students to get used to learning on their own after understanding the teacher's explanation, focusing on working on projects, and developing interests according to their wishes. Meanwhile, external factors include a supportive family environment, a supportive community environment, supportive teachers, and friends who influence all attitudes of students. Factors that influence learning independence in the Project to Strengthen Pancasila Student Profiles (P5) for class II B and V B SD N Kleco II are influenced by internal factors and external factors.

This research aims to determine the implementation of the project to strengthen the Pancasila student profile (P5) in Elementary school. This research method uses qualitative research. Primary data from this study were the results of interviews with class I and IV subject teachers and students. While secondary data is in the form of research photo documentation, project implementation photo documentation, and project modules. Data collection techniques used are interviews and documentation. Test the validity of the data using technique and source triangulation. The data analysis technique used is the Miles and Huberman technique. The results of this study indicate that the implementation of the Pancasila student profile strengthening project (P5) is to the guidelines. However, several components have not been implemented / attitude of learners. Barriers to students are mood swings, disruptive behavior in class, making dummy pancakes, and lack of self-motivation in learning. The solution to teacher barriers is to cooperate with IOM and teacher fees, carry out extra supervision, form team groups, and maintain emotional self-esteem. The student's solution is to ask for help from the project teacher and accompanying parents and to distribute tasks evenly within the group.

This study aims to explain and describe the ability to think critically mathematically in terms of Multiple Intelligence in fifth grade students at elementary school. The method used in this study is a qualitative approach with a case study research design. Sampling was carried out using purposive sampling technique. The data collection technique uses triangulation using data from document analysis, questionnaires, interviews, and observations. Data analysis was carried out descriptively and qualitatively. Based on the research results, it is known that the ability to think critically basically has different levels of ability when viewed from the perspective of multiple intelligences. Students have a lower level of critical thinking skills than their peers; However, they show extraordinary intelligence in certain areas. Students who fall into the categories of linguistic intelligence, musical intelligence, intrapersonal intelligence, and natural intelligence show lower order thinking skills (Lower Order Thinking/LOT) on mathematical critical thinking performance. Students with logical-mathematical intelligence and spacial intelligence category show High Order Thinking (HOT) on mathematical critical thinking performance. Students who fall into the category of bodily-kinesthetic intelligence and interpersonal intelligence show Middle Order Thinking (MOT) on mathematical critical thinking performance. This study focuses on the characteristics of students' multiple intelligences towards the level of critical thinking mathematics so that it can be used as a reference for classifying students in the process of learning mathematics.
