Sucesos de vida de escolares entre los 13 y 18 años de edad, de las instituciones educativas Braulio González sede campestre e hispano ingles del municipio de Yopal departamento de Casanare

TablasEl presente trabajo de investigación descriptivo hace referencia a “Sucesos de Vida”- Versión para adolescentes de Emilia Lucio –Gómez Maqueo y Consuelo Durán Patiño. (2003), en escolares entre los 13 a 18 años de edad de las Instituciones Educativas Braulio González e Hispano Ingles del municipio de Yopal Casanare, cuya intención es precisamente identificar aquellos sucesos de vida que presentan desde sus diferentes áreas de funcionamiento. Según Burgos (2008), los cambios en la adolescencia se desarrollan muy rápido no solo física sino emocionalmente, que aunque son positivos, en ocasiones tienden hacer confusos no solo para los adultos sino para el joven. Por lo tanto, se tiene en cuenta en esta investigación siete ámbitos de su vida cotidiana, como la familia, salud, escolar, social, personal, logros y fracasos y problemas de conducta; como se menciona en el instrumento “Sucesos de Vida”- Versión para adolescentes de Emilia Lucio –Gómez Maqueo y Consuelo Durán Patiño. (2003). La muestra participativa en el presente estudio corresponde a cuarenta y seis (46) estudiantes por institución, para un total de noventa y dos (92); desde los grados séptimo a once con edades entre los 13 y 18 años, como lo exige el instrumento. En cuanto a los resultados obtenidos, se logra evidenciar que el área que mayor puntúa en el instrumento corresponde al área familiar; donde un 23.91% de la muestra presenta un riesgo “alto”, lo cual puede sugerir un importante grado de vulnerabilidad de sufrir algún tipo de alteración emocional o psicológica, y un 10.86% presenta riesgo “medio”, lo que indica que éstos jóvenes pueden experimentar más sucesos estresantes de lo habitual. En los ámbitos social, escolar y de la salud se presenta un porcentaje un poco más bajo, con un 15.21% respectivamente.This descriptive research work refers to events of life (adolescent version) of students between 13-18 years of Braulio Gonzalez and Hispano Ingles schools of Yopal Casanare city, whose intention is to precisely identify those events life presenting their different performance areas. According to Burgos (2008), the changes in adolescence occur very soon not only physically but emotionally, although positive, sometimes confusing tend to do not only for adults but for the young. Therefore, taken into account in this investigation seven areas of their daily lives, such as family, health, school, social, personal, successes and failures and behavioral problems as mentioned in the instrument “Sucesos de Vida”-Versión para adolescentes de Emilia Lucio –Gómez Maqueo y Consuelo Durán Patiño. (2003). The Participatory sample is forty-six (46) students by institution, for a total of ninety two (92); since seventh to eleventh grade, aged between 13 and 18 years as required by the instrument. As for the results obtained, it is possible to show that the largest area rate in the instrument is the family area; where 23.91% of the sample show a "high" risk, which may suggest a significant vulnerability to suffer some kind of emotional or psychological disorder, and 10.86% have "medium" risk, indicating that these young people can experience more stressful events than usual. In the social area, educational area and health area fields a slightly lower but significant percentage, a 15.21%, respectively

Zeolite and Removal of Ammonium in Sewage

One of the problems that represent a nuisance for the citizens of the city of Portoviejo in Ecuador is related to the treatment to the waste water, since in their majority they are poured as effluents to the river Portoviejo. This situation causes at different times of the year that there is an unpleasant smell that affects the environment. In the work technical solutions are analyzed to avoid such annoyance; but the most important thing is to avoid contaminating the river waters with the dumping of pollutants that alter the quality of the water. A variant aimed at ammonium removal is proposed using zeolite filters

Increased chemerin serum levels in hyperandrogenic and normoandrogenic women from Argentina with polycystic ovary syndrome

Aim: To assess serum chemerin levels and investigate the association of chemerin with the hyperandrogenic and normoandrogenic phenotypes of Polycystic Ovary Syndrome (PCOS) and with the metabolic status of the analyzed population. Material and methods: A cross-sectional study was conducted on 106 women with PCOS and 60 healthy controls from Argentina. Patients were classified as showing a hyperandrogenic or normoandrogenic phenotype. Participants underwent anthropometric and clinical evaluation and markers of cardiovascular risk, insulin resistance, metabolic syndrome (MS), and serum chemerin levels were assessed. Results: PCOS patients showed increased levels of chemerin. In adjusted models for age and body mass index (BMI), chemerin was associated with markers of metabolic status. The analysis of chemerin levels considering the cutoff values of BMI, homeostatic model of insulin sensitivity (HOMA-IR) and TG/HDL marker showed that PCOS patients always presented higher levels of chemerin than controls. PCOS group showed increased chemerin levels independently of the presence of MS. Conclusion: PCOS patients always showed increased levels of chemerin independently of their phenotype and presence of overweight, as well as higher levels of chemerin than controls when considering the cutoff values of HOMA-IR and TG/HDL. Therefore, argentine women with PCOS display increased chemerin levels independently of their metabolic or androgenic status.Fil: Abruzzese, Giselle Adriana.

Efficient Alkyne Semihydrogenation Catalysis Enabled by Synergistic Chemical and Thermal Modifications of a PdIn MOF

Recently, there has been a growing interest in using MOF templating to synthesize heterogeneous catalysts based on metal nanoparticles on carbonaceous supports. Unlike the common approach of direct pyrolysis of PdIn-MOFs at high temperatures, this work proposes a reductive chemical treatment under mild conditions before pyrolysis (resulting in PdIn-QT). The resulting material (PdIn-QT) underwent comprehensive characterization via state-of-the-art aberration-corrected electron microscopy, N2 physisorption, X-ray absorption spectroscopy, Raman, X-ray photoelectron spectroscopy, and X-ray diffraction. These analyses have proven the existence of PdIn bimetallic nanoparticles supported on N-doped carbon. In situ DRIFT spectroscopy reveals the advantageous role of indium (In) in regulating Pd activity in alkyne semihydrogenation. Notably, incorporating a soft nucleation step before pyrolysis enhances surface area, porosity, and nitrogen content compared to direct MOF pyrolysis. The optimized material exhibits outstanding catalytic performance with 96% phenylacetylene conversion and 96% selectivity to phenylethylene in the fifth cycle under mild conditions (5 mmol phenylacetylene, 7 mg cat, 5 mL EtOH, R.T., 1 H2 bar)

Babesia bovis AMA-1, MSA-2c and RAP-1 contain conserved B and T-cell epitopes, which generate neutralizing antibodies and a long-lasting Th1 immune response in vaccinated cattle

Vaccines against bovine babesiosis must, ideally, induce a humoral immune response characterized by neutralizing antibodies against conserved epitopes and a cellular Th1 immune response. In Babesia bovis, proteins such as AMA-1, MSA-2c, and RAP-1 have been characterized and antibodies against these proteins have shown a neutralizing effect, demonstrating the implication of B and T-cell epitopes in the immune response. There is evidence of the existence of B and T-cell epitopes in these proteins, however, it remains to be defined, the presence of conserved peptides in strains from around the world containing B and T-cell epitopes, and their role in the generation of a long-lasting immunity. The aim in this paper was to identify peptides of Babesia bovis AMA-1, MSA-2c, and RAP-1 that elicit a neutralizing and long-lasting Th1 immune response. Peptides containing B-cell epitopes of AMA-1, MSA-2c and RAP-1, were identified. The immune response generated by each peptide was characterized in cattle. All peptides tested induced antibodies that recognized intraerythrocytic parasites, however, only 5 peptides generated neutralizing antibodies in vitro: P2AMA-1 (6.28%), P3MSA-2c (10.27%), P4MSA-2c (10.42%), P1RAP-1 (32.45%), and P4RAP-1 (36.98%). When these neutralizing antibodies were evaluated as a pool, the inhibition percentage of invasion increased to 52.37%. When the T cellular response was evaluated, two peptides: P3MSA2c and P2AMA1 induced a higher percentage (>70%) of activated CD4 +/CD45RO+ T cells than unstimulated cells. Additionally, both peptides induced the production of gamma interferon (IFN-) in PBMCs from vaccinated cattle after one year proving the implication of a long-lasting Th1 immune response. In conclusion, we identified conserved peptides containing B and T-cell epitopes in antigens of B. bovis that elicit a Th1 immune response and showed evidence that peptides from the same protein elicit different immune responses, which has implication for vaccine development in bovine babesiosis.Instituto de PatobiologíaFil: Hidalgo-Ruiz, Mario.
