El Emprendimiento en la educación agrícola a la luz de tres enfoques epistemológicos: Una revisión sistemática

Una de las maneras para superar las necesidades económicas y productivas de las diferentes zonas rurales, es a través del emprendimiento. Por este motivo estudiar desde epistemologías como la fenomenología, el constructivismo, y el empirismo, logra abarracar las diferentes preguntas y brechas que se presentan en las incidencias para el desarrollo formación de los jóvenes en actividades de emprendimiento agrícola. Sin embargo, el emprendimiento da soluciones a las problemáticas sociales en cada una de las regiones. De esta manera también logra estimular en los jóvenes de los colegios agrícolas nociones de emprendimiento, y genera aportes en la transformación de los entornos, aumentando las dinámicas económicas adaptadas en las regiones, que finalmente aportan al desarrollo de los jóvenes, y la obtención de capacidades en emprendimiento. Se realiza una revisión sistemática de artículos publicados en revistas indexadas en inglés y español de aportes investigativos en temas de formación en emprendimiento agrícola, las experiencias que se dan de acuerdo con las condiciones y características de cada uno de los diferentes estudios realizados, y su adaptabilidad en los entornos rurales a partir de los paradigmas que enmarcan estas condiciones en cada una de las regiones a nivel global

Effects of the antiandrogen flutamide on the expression of protein kinase C isoenzymes in LNCaP and PC3 human prostate cancer cells

Flutamide is a nonsteroidal antiandrogen that is frequently used for total androgen blockage in the treatment of advanced prostate cancer. We investigated the effect of this antiandrogen on the expression of protein kinase C (PKC) isoenzymes (a, b1, e, f) that are involved in cell growth, apoptosis and neoplastic transformation. Androgen-dependent (LNCaP) and independent (PC3) human prostate cancer cells were cultured in a medium that contained fetal bovine serum (FBS) or charcoal-stripped serum (CSS) and treated with 10 lM flutamide. The expression of PKC isoenzymes and the androgen receptor (AR) were analyzed by Western blot and RT-PCR, respectively. Serum steroids differentially regulate the expression of PKC isoenzymes in LNCaP and PC3 cells. Flutamide up-regulated the expression of a, b1 and f, but not e, PKC isoenzymes in CSS-LNCaP cells. These results were not homogeneously reproduced in the presence of androgens. We observed an opposite effect of flutamide, compared to CSS, on PKCb1 isoform expression in CSS-LNCaP suggesting that this antiandrogen exerts an agonistic effect. In PC3 cells flutamide potentiated the expression of the four PKC isoenzymes in almost all conditions tested (FBS- and CSScultured cells). Such effect of flutamide in PC3 cells is independent of AR since no expression of AR was detected. These results provide new evidence on antagonistic/agonistic responses of prostate cancer cells to antiandrogen drugs that are widely used in therapy and show that flutamide can elicit responses in prostate cancer cells that do not express AR

Ultraviolet-Visible and High-Resolution Mass Spectrometry for the Identification of Cyclopropyl-Fentanyl in the First Fatal Case in Spain

A 24-year-old white male was found dead at home in Madrid, Spain.The medical examiner indicated a dead person sat forward on thebed. The suspected cause of death was poly-drug intoxication, sincedrug paraphernalia was located at home and the absence of injuries inAQ8arms, forearms and hands was observed. The autopsy was performed48 h later.The histological examinations performed on stained samplesshowed no traumatic signs in both the cranial and brain cavity. Bothlungs presented intense congestive parenchyma, with fluid and darkblood. Pericardial sac (240-g heart) presented without findings ofinterest whereas spirits presented fluid and dark blood. In the abdominalcavity, the liver presented slight congestion. The stomach, withdark-brown pasty content, had the appearance of poorly digestedblood, with hyperemia in the mucosa. Kidneys were very congestedand there was a small volume of cloudy urine in the bladder.All biological samples (blood, vitreous humor and urine) werecollected at autopsy by the medical examiner and sent to INTCF.Later, non-biological samples (paraphernalia) were also submittedfrom the police unit to INTCF, ordered by the judge for a comprehensivetoxicological screening

Raoultella planticola pneumonia in a patient with critical COVID-19

Raoultella planticola is a bacterium that has been recently described in the literature as an emerging pathogen that causes urinary, abdominal, and lung infections. We present the case of a 63-year-old overweight and with dyslipidemia that was hospitalized because of a SARS-CoV-2 infection. He developed R. planticola and E. aerogenes superinfections. He was treated with cefepime for seven days, and he recovered uneventfully

Effects of lng Mutations on LngA Expression, Processing, and CS21 Assembly in Enterotoxigenic Escherichia coli E9034A

Enterotoxigenic Escherichia coli (ETEC) is a major cause of morbidity in children under 5 years of age in low- and middle-income countries and a leading cause of traveler's diarrhea worldwide. The ability of ETEC to colonize the intestinal epithelium is mediated by fimbrial adhesins, such as CS21 (Longus). This adhesin is a type IVb pilus involved in adherence to intestinal cells in vitro and bacterial self-aggregation. Fourteen open reading frames have been proposed to be involved in CS21 assembly, hitherto only the lngA and lngB genes, coding for the major (LngA) and minor (LngB) structural subunit, have been characterized. In this study, we investigated the role of the LngA, LngB, LngC, LngD, LngH, and LngP proteins in the assembly of CS21 in ETEC strain E9034A. The deletion of the lngA, lngB, lngC, lngD, lngH, or lngP genes, abolished CS21 assembly in ETEC strain E9034A and adherence to HT-29 cells was reduced 90%, compared to wild-type strain. Subcellular localization prediction of CS21 proteins was similar to other well-known type IV pili homologues. We showed that LngP is the prepilin peptidase of LngA, and that ETEC strain E9034A has another peptidase capable of processing LngA, although with less efficiency. Additionally, we present immuno-electron microscopy imagens to show that the LngB protein could be localized at the tip of CS21, and probably helps to control CS21 length. In conclusion, our results demonstrate that the LngA, LngB, LngC, LngD, LngH, and LngP proteins are essential for CS21 assembly, as well as for bacterial aggregation and adherence to HT-29 cells

Perception of wildlife from various religious views: A tool to promote environmental education in the Osa Peninsula

En la península de Osa, al sur de Costa Rica, la cacería y el comercio de la fauna silvestre son prácticas extendidas que ponen en riesgo su conservación. Los líderes religiosos podrían ser actores importantes si se integra en sus discursos ideas sobre esta problemática, pues ellos tienden a crear enlaces profundos con la comunidad. Con el objetivo de conocer la percepción de los líderes religiosos frente a la problemática ambiental local, se realizaron entrevistas a profundidad. En general mostraron sensibilidad hacia la naturaleza y los problemas ambientales actuales. Existió una aceptación sobre la caza de subsistencia, pero no así de la caza deportiva ni comercial. Se encontró una buena disposición de aprender sobre la problemática ambiental y las vías para su mitigación, así como elementos en sus doctrinas que pueden usarse para canalizar estrategias de educación ambiental.In the Osa peninsula in southern Costa Rica, hunting and wildlife trade are common practices that threaten biodiversity conservation. Religious leaders could play an important role if they integrate in their speeches ideas about these issues, as they tend to create deep links with the community. In order to understand the perception of religious leaders against local environmental issues they were interviewed in depth. In general they showed sensitivity to nature and the current environmental problems. They showed an acceptance on subsistence hunting, but not for commercial or sport hunting. Also religious leaders showed a willingness to learn about environmental issues and ways to mitigate them, as well as elements in their doctrines that can be used to channel environmental education strategies.Fil: Mazzolari, Ana Clara.

Generation of Arc-Like and OIB-Like Magmas Triggered by Slab Detachment in the Eastern Mexican Alkaline Province: Petrological Evidence from the Cenozoic Sierra de San Carlos-Cruillas Complex, Tamaulipas

The origin of the Eastern Mexican Alkaline Province has been explained by landward arc migration and subsequent asthenospheric upwelling after slab roll-back of the Farallon Plate. In this work, we present new petrographic, mineral chemical, geochemical, and geochronological data of the Sierra de San Carlos-Cruillas (SSCC), one of the most important complexes in the province. This information, together with published data, helped us to reinterpret the tectonic processes operating during the generation of this province, as well as the mantle sources involved in the partial melting process. Detailed geochemical analysis suggests the participation of two types of metasomatized mantle regions: a lithospheric source modified by past subduction processes and an asthenospheric source slightly affected by carbonatite-related metasomatism. Variations in the partial melting degrees controlled the extent of magma enrichment in the latter. Major and trace element geochemistry, together with geochronological data and field relations, evinced an older post-orogenic setting related to the arc-like rocks (Eocene) and a younger intraplate extensional environment associated with all enriched igneous rocks (Oligocene-Miocene). Bivariate diagrams of SiO2-trace element ratios and multi-element patterns indicate that magmas from the SSCC complex dominantly evolved through fractional crystallization with a limited crustal contribution. Petrographic and mineral chemistry features suggest that some of these magmas experienced open-system processes (e.g. recharge events) in a complex and dynamic magmatic feeding system. In contrast to the traditional petrotectonic model, we propound that the passage and subsequent foundering of the Hess conjugate under northeastern Mexico resulted in its eclogitization and triggered slab tearing and succeeding detachment. This latter process occasioned mantle upwelling and the partial melting of the two recognized metasomatized mantle sources, thus generating the San Carlos-Cruillas magmatism

A primary healthcare information intervention for communicating cardiovascular risk to patients with poorly controlled hypertension: The Education and Coronary Risk Evaluation (Educore) study-A pragmatic, cluster-randomized trial

PURPOSE: Uncertainty exists regarding the best way to communicate cardiovascular risk (CVR) to patients, and it is unclear whether the comprehension and perception of CVR varies according to the format used. The aim of the present work was to determine whether a strategy designed for communicating CVR information to patients with poorly controlled high blood pressure (HBP), but with no background of cardiovascular disease, was more effective than usual care in the control of blood pressure (BP) over the course of a year. METHODS: A pragmatic, two-arm, cluster-randomized controlled trial was performed. Consecutive patients aged 40-65 years, all diagnosed with HBP in the last 12 months, and all of whom showed poor control of their condition (systolic BP ≥140 mmHg and/or diastolic BP ≥90 mmHg), were recruited at 22 primary healthcare centres. Eleven centres were randomly assigned to the usual care arm, and 11 to the informative intervention arm (Educore arm). At the start of the study, the Educore arm subjects were shown the "low risk SCORE table", along with impacting images and information pamphlets encouraging the maintenance of good cardiovascular health. The main outcome variable measured was the control of HBP; the secondary outcome variables were SCORE table score, total plasma cholesterol concentration, use of tobacco, adherence to prescribed treatment, and quality of life. RESULTS: The study participants were 411 patients (185 in the Educore arm and 226 in the usual care arm). Multilevel logistic regression showed that, at 12 months, the Educore intervention achieved better control of HBP (OR = 1.57; 1.02 to 2.41). No statistically significant differences were seen between the two arms at 12 months with respect to the secondary outcomes. CONCLUSIONS: Compared to usual care, the Educore intervention was associated with better control of HBP after adjusting for age, baseline SBP and plasma cholesterol, at 12 months.This study was funded by the Spanish Ministry of Science and Innovation via the Instituto de Salud Carlos III, Subprograma de Proyectos de Investigación en Evaluación de Tecnologías Sanitarias y Servicios de Salud (PI 09/90354), and the Fundación de Investigación e Innovación Biomédica en Atención Primaria (FIIBAP).
