ABSTRACT: Pectobacterium chrysanthemi is the causative agent of soft rot that commonly affects organic banana crops around the planet. Current phytosanitary control policies are based on the symptoms caused by the disease. However, since there are other species that cause similar symptoms, pathogenicity tests are used to which biochemical tests must be added to identify the bacteria, dispensing with molecular tests that, in contrast, would allow obtaining more specific results and in less time. time. This article presents an alternative methodology for the rapid and specific diagnosis of soft rot caused by Pectobacterium chrysanthemi in organic banana crops in Peru. Detection by virulence of the bacteria in host tissue of Solanum tuberosum and PCR of the internal transcribed spacer (ITS) of the 16S/23S rDNA allows timely management of the disease. The results demonstrate that in the complex between the pathogenicity test and the ITS-16S/23S PCR assay it is possible to detect Pectobacterium chrysanthemi in a period of 8 days, 3 hours and 15 minutes, demonstrating that this method is more efficient than conventional tests. biochemical tests usually used for the diagnosis of soft rot in Musa sp.

RESUMEN: Pectobacterium chrysanthemi es el agente causal de la pudrición blanda que comúnmente afecta los cultivos de banano orgánico de todo el planeta. Las políticas actuales de control fitosanitario se basan en la sintomatología causada por la enfermedad. Sin embargo, al existir otras especies que causan síntomas similares, se recurre a pruebas de patogenicidad a las que se debe adicionar pruebas bioquímicas para llegar a identificar la bacteria, prescindiendo de ensayos moleculares que, en contraste, permitirían obtener resultados más específicos y en menor tiempo. Este artículo presenta una metodología alternativa en el diagnóstico rápido y específico de la pudrición blanda causada por Pectobacterium chrysanthemi en cultivos de banano orgánico del Perú. La detección mediante virulencia de la bacteria en tejido hospedante de Solanum tuberosum y la PCR del espaciador transcrito interno (ITS) del ADNr 16S/23S, permite el manejo oportuno de la enfermedad. Los resultados demuestran que en el complejo entre la prueba de patogenicidad y el ensayo PCR- ITS 16S/23S es posible detectar a Pectobacterium chrysanthemi en un periodo de 8 días, 3 horas y 15 minutos, demostrando que este método es más eficiente que las pruebas bioquímicas usualmente empleadas para el diagnóstico de la pudrición blanda en Musa sp.

ABSTRACT The emissions of CH4 and CO2, the primary greenhouse gases, have a significant impact on radiative forcing. This study investigated these gases along the Cananéia-Iguape estuarine system on the southern coast of the State of São Paulo, Brazil, which is a mangrove region characterized by low anthropogenic impact and a sparse population. As such, this area provides an ideal location for identifying natural emissions and background concentrations. The data for this study were collected using a portable gas analyzer (LGR-ICOSTM GLA131), known for its high sensitivity and precision in detecting gases, mounted on a research boat. The results obtained were promising for both gases. A small variability in CH4 concentrations was observed along the route, ranging from 1.84 ppm to 1.95 ppm, while CO2, showed greater variation in values obtained during routes, ranging from approximately 411 ppm to 575 ppm. This study underscores the importance of investigating areas with minimal environmental impact. Together with future analyses, this research should help improve Greenhouse Gas (GHG) inventories in Brazil by providing valuable baseline data for comparisons with more impacted areas.

Abstract There is an interaction between dendrocytes and mast cells in the skin. However, in elastosis-related diseases such as actinic cheilitis (AC) and lower lip squamous cell carcinoma (LLSCC), this interaction remains unknown. We investigated the presence of intact and degranulated mast cells in AC and LLSCC. Associations of mast cells with factor XIIIa+ dendrocytes and inflammatory infiltrate were assessed. Forty cases of AC (20 with low-grade and 20 with high-grade epithelial dysplasia), 50 cases of LLSCC, and 10 cases of normal oral mucosa were evaluated. Toluidine blue staining was performed to identify mast cells, and mast cell densities were calculated in the inflammatory infiltrate. Factor XIIIa+ dendrocytes were immunohistochemically quantified. The highest ratio of intact/degranulated mast cells density was detected in LLSCC (5.9 cells/mm2), followed by AC with high-grade epithelial dysplasia (4.8 cells/mm2). Statistically significant differences were found in the density of intact mast cells compared to degranulated mast cells in AC with low-grade epithelial dysplasia (p<0.001), AC with high-grade epithelial dysplasia (p=0.005), and LLSCC (p<0.001). A positive correlation between degranulated mast cells and total inflammatory infiltrate (p=0.03) was observed in the LLSCC group. The expression of factor XIIIa+ dendrocytes was highest in AC with low-grade epithelial dysplasia (16.5 cells/mm2). The link between mast cell density, factor XIIIa+ dendrocytes, and inflammatory infiltrate indicates a potential crosstalk in lip carcinogenesis. skin However elastosisrelated elastosis related (AC , (LLSCC) unknown XIIIa assessed (2 lowgrade low grade 2 highgrade high dysplasia, dysplasia) 5 1 evaluated quantified intactdegranulated 5.9 59 9 (5. cells/mm2, cellsmm2 cellsmm cells/mm2 mm2 mm cells/mm2) 4.8 48 4 8 (4. cells/mm2. . p<0.001, p0001 p p<0.001 0 001 (p<0.001) p=0.005, p0005 p=0.005 005 (p=0.005) p<0.001. p=0.03 p003 03 (p=0.03 group 16.5 165 16 (16. carcinogenesis (LLSCC ( 5.

ABSTRACT The study evaluated the repeatability of the superovulatory response in 12 Australian Merino ewes during the breeding season in one (G1), three (G2), and four (G3) consecutive years. A modified protocol was used based on 200 mg pFSH in eight decreasing doses (12h intervals) and supportive strategies such as changing the CIDR at day 7, spraying the horns with heparinized saline during the procedure, and use of Flunixin Meglumine. No significant differences were found in the total number of structures recovered during the years of application of the superovulation protocol (G1=8±2, G2=18±3, G3=19±4; p>0.05). High repeatability was observed, both for the total number of embryos and for the number of transferable embryos in G2 and G3. Superovulatory treatment for 3 and 4 successive years did not affect the efficacy of embryo retrieval.

RESUMEN El estudio evaluó la repetibilidad de la respuesta superovulatoria en 12 ovejas Merino Australiano durante la estación reproductiva en uno (G1), tres (G2) y cuatro (G3) años consecutivos. Se utilizó un protocolo modificado basado en 200 mg de pFSH en ocho dosis decrecientes (intervalos de 12 h) y estrategias de apoyo tales como el cambio del CIDR al día 7, el rociado de los cuernos durante el procedimiento con solución salina con heparina y el uso de Flunixin Meglumine. No se encontraron diferencias significativas en el número total de estructuras recuperadas durante los años de aplicación del protocolo de superovulación (G1=8±2, G2=18±3, G3=19±4; p>0.05). Se observó una alta repetibilidad, tanto para el número total de embriones como para el número de embriones transferibles en G2 y G3. El tratamiento superovulatorio durante 3 y 4 años sucesivos no afectó la eficacia de la recuperación de embriones.

ABSTRACT The SISBIOTA-BRASIL was a three-year multimillion-dollar research program of the Brazilian government to document plants and animals in endangered/understudied areas and biomes in Brazil. Distributional patterns and the historical events that generated them are extensively unknown regarding Brazilian fauna and flora. This deficiency hinders the development of conservation policies and the understanding of evolutionary processes. Conservation decisions depend on precise knowledge of the taxonomy and geographic distribution of species. Given such a premise, we proposed to research the diversity of Diptera of the Brazilian western arc of Amazon, Cerrado, and Pantanal in the states of Mato Grosso, Mato Grosso do Sul, and Rondônia. Three important biomes of the South American continent characterize these Brazilian states: Amazon forest, Cerrado (Brazilian Savannah), and Pantanal. Besides their ecological relevance, these biomes historically lack intensive entomological surveys. Therefore, they are much underrepresented in the Brazilian natural history collections and in the scientific literature, which is further aggravated by the fact that these areas are being exponentially and rapidly converted to commercial lands. Our project involved over 90 collaborators from 24 different Brazilian institutions and one from Colombia among researchers, postdocs, graduate and undergraduate students, and technicians. We processed and analyzed nearly 300,000 specimens from ~60 families of Diptera collected with a large variety of methods in the sampled areas. Here, we provide a detailed overview of the genera and species diversity of 41 families treated. Our results point to a total of 2,130 species and 514 genera compiled and identified for the three states altogether, with an increase of 41% and 29% in the numbers of species and genera known for the three states combined, respectively. Overall, the 10 most species-rich families were Tachinidae, Cecidomyiidae, Tabanidae, Psychodidae, Sarcophagidae, Stratiomyidae, Bombyliidae, Syrphidae, Tephritidae, and Asilidae. The 10 most diverse in the number of genera were Tachinidae, Stratiomyidae, Asilidae, Mycetophilidae, Syrphidae, Tabanidae, Muscidae, Dolichopodidae, Sarcophagidae, and Chloropidae. So far, 111 scientific papers were published regarding taxonomic, phylogenetic, and biogeographical aspects of the studied families, with the description of 101 new species and three new genera. We expect that additional publications will result from this investigation because several specimens are now curated and being researched by specialists.

Abstract Background Heart Failure is a significant public health problem leading to a high burden of physical and psychological symptoms despite optimized therapy. Objective To evaluate primarily the impact of a Stress Reduction, Meditation, and Mindfulness Program on stress reduction of patients with Heart Failure. Methods A randomized and controlled clinical trial assessed the effect of a stress reduction program compared to conventional multidisciplinary care in two specialized centers in Brazil. The data collection period took place between April and October 2019. Thirty-eight patients were included and allocated to the intervention or control groups. The intervention took place over 8 weeks. The protocol assessed the scales of perceived stress, depression, quality of life, anxiety, mindfulness, quality of sleep, a 6-minute walk test, and biomarkers analyzed by a blinded team, considering a p-value <0.05 statistically significant. Results The intervention resulted in a significant reduction in perceived stress from 22.8 ± 4.3 to 14.3 ± 3.8 points in the perceived stress scale-14 items in the intervention group vs. 23.9 ± 4.3 to 25.8 ± 5.4 in the control group (p-value<0.001). A significant improvement in quality of life (p-value=0.013), mindfulness (p-value=0.041), quality of sleep (p-value<0.001), and the 6-minute walk test (p-value=0.004) was also observed in the group under intervention in comparison with the control. Conclusion The Stress Reduction, Meditation, and Mindfulness Program effectively reduced perceived stress and improved clinical outcomes in patients with chronic Heart Failure. therapy Reduction Meditation Brazil 2019 Thirtyeight Thirty eight groups weeks depression anxiety 6minute minute 6 team pvalue p value 005 0 05 <0.0 228 22 22. 43 4 3 4. 143 14 14. 38 3. scale14 scale scale-1 vs 239 23 9 23. 258 25 25. 54 5 5. pvalue<0.001. pvalue0001 value<0.001 . 001 (p-value<0.001) pvalue=0.013, pvalue0013 value=0.013 , 013 (p-value=0.013) pvalue=0.041, pvalue0041 value=0.041 041 (p-value=0.041) pvalue<0.001, pvalue=0.004 pvalue0004 value=0.004 004 (p-value=0.004 201 00 <0. 2 1 scale1 scale- pvalue<0.001 pvalue000 value0001 value<0.00 (p-value<0.001 pvalue=0.013 pvalue001 value0013 value=0.01 01 (p-value=0.013 pvalue=0.041 pvalue004 value0041 value=0.04 04 (p-value=0.041 pvalue=0.00 value0004 value=0.00 (p-value=0.00 20 <0 pvalue<0.00 pvalue00 value000 value<0.0 (p-value<0.00 pvalue=0.01 value001 value=0.0 (p-value=0.01 pvalue=0.04 value004 (p-value=0.04 pvalue=0.0 (p-value=0.0 < pvalue<0.0 pvalue0 value00 value<0.

Abstract Background Anabolic androgenic steroid (AAS) abuse has been associated with coronary artery disease (CAD). Pericoronary fat attenuation (pFA) is a marker of coronary inflammation, which is key in the atherosclerotic process. Objective To evaluate pFA and inflammatory profile in AAS users. Methods Twenty strength-trained AAS users (AASU), 20 AAS nonusers (AASNU), and 10 sedentary controls (SC) were evaluated. Coronary inflammation was evaluated by mean pericoronary fat attenuation (mPFA) in the right coronary artery (RCA), left anterior descending coronary artery (LAD), and left circumflex (LCx). Interleukin (IL)-1 (IL-1), IL-6, IL-10, and TNF-alpha were evaluated by optical density (OD) in a spectrophotometer with a 450 nm filter. P<0.05 indicated statistical significance. Results AASU had higher mPFA in the RCA (-65.87 [70.51-60.70] vs. -78.07 [83.66-72.87] vs.-78.46 [85.41-71.99] Hounsfield Units (HU), respectively, p<0.001) and mPFA in the LAD (-71.47 [76.40-66.61] vs. -79.32 [84.37-74.59] vs. -82.52 [88.44-75.81] HU, respectively, p=0.006) compared with AASNU and SC. mPFA in the LCx was not different between AASU, AASNU, and SC (-72.41 [77.17-70.37] vs. -80.13 [86.22-72.23] vs. -78.29 [80.63-72.29] HU, respectively, p=0.163). AASU compared with AASNU and SC, had higher IL-1, (0.975 [0.847-1.250] vs. 0.437 [0.311-0.565] vs. 0.530 [0.402-0.780] OD, respectively, p=0.002), IL-6 (1.195 [0.947-1.405] vs. 0.427 [0.377-0.577] vs. 0.605 [0.332-0.950] OD, p=0.005) and IL-10 (1.145 [0.920-1.292] vs. 0.477 [0.382-0.591] vs. 0.340 [0.316-0.560] OD, p<0.001). TNF-α was not different between the AASU, AASNU, and SC groups (0.520 [0.250-0.610] vs. 0.377 [0.261-0.548] vs. 0.350 [0.182-430]), respectively. Conclusion Compared with ASSNU and controls, AASU have higher mPFA and higher systemic inflammatory cytokines profile suggesting that AAS may induce coronary atherosclerosis through coronary and systemic inflammation.

ABSTRACT Objective: The aim of this study was to investigate the factors associated with hypoglycemia and severe hypoglycemia (SH) in individuals with type 1 diabetes mellitus (T1D) in Brazil. Materials and methods: This multicenter, cross-sectional study was conducted between August 2011 and August 2014 across 10 Brazilian cities. The data were obtained from 1,760 individuals with T1D. Sociodemographic and clinical characteristics related to hypoglycemic events in the previous 4 weeks were evaluated. Results: Of 1,760 individuals evaluated, 1,319 (74.9%) reported at least one episode of hypoglycemia in the previous 4 weeks. The main factors associated with hypoglycemia were lower hemoglobin A1c (HbA1c) level, better adherence to self-monitoring of blood glucose (SMBG), and higher education level. Episodes of SH were reported by 251 (19%) individuals who, compared with subjects with nonsevere hypoglycemia, received lower doses of prandial insulin and higher doses of basal insulin, in addition to reporting less frequent use of long-acting basal insulin analogs. The percentage of SH episodes was evenly distributed across all ranges of HbA1c levels, and there were no correlations between the mean number of nonsevere or severe hypoglycemic events and HbA1c values. Higher alcohol consumption and more frequent hospitalizations were independently associated with SH. Conclusion: Although individuals presenting with hypoglycemia had lower HbA1c values than those not presenting hypoglycemia, there were no correlations between the number of nonsevere hypoglycemia or SH and HbA1c values. Also, the frequency of SH was evenly distributed across all ranges of HbA1c values. Better adherence to SMBG and higher education level were associated with hypoglycemia, while alcohol consumption, higher doses of basal insulin, and more frequent hospitalizations in the previous year were associated with SH.

Resumen Nuevos datos de campo, petrografía, geoquímica y geocronología U-Pb en circón permiten redefinir el batolito de Ibagué y proponer nuevas unidades. El batolito de Ibagué, al norte de la Falla de Ibagué, ha sido dividido en la Metatonalita de Anzoátegui (~194,7 km2) y la Tonalita de Ibagué (-278 km2). Al sur de la falla de Ibagué conserva el nombre de batolito de Ibagué con una extensión de ~3200 km2, debido a la escisión de los gabros de Belalcázar y Los Guayabos de edad Carbonífera, los granitos de Ortega y La Plata de edad Pérmica, y la Cuarzomonzodiorita de Páez de edad Jurásico temprano. La Metatonalita de Anzoátegui y la Tonalita de Ibagué se componen de metatonalitas, tonalitas y granodioritas calco-alcalinas metaluminosas, con edades U-Pb para la Metatonalita de Anzoátegui entre 158,2+1,2/-0,4 y 150,17±0,86 Ma y para la Tonalita de Ibagué entre 145,71+0,72/-1,42 Ma y 138,48±0,95 Ma, Jurásico medio a Cretácico inferior. El batolito de Ibagué está constituido por tonalitas, granodioritas y monzogranitos calco-alcalinos a calco-alcalinos de alto K, metaluminosos y peraluminosos, con edades entre 171,5±1,3 y 137,9±1,0 Ma. El batolito de Ibagué, la Metatonalita de Anzoátegui y la Tonalita de Ibagué son granitoides cálcicos de arco, con anomalías negativas de Nb, Ti y P. La posición geotectónica, la composición petrográfica y química, y las edades de cristalización permitieron correlacionar el batolito de Ibagué, La Metatonalita de Anzoátegui y la Tonalita de Ibagué con los batolitos de Segovia y Los Alisales, la Granodiorita de Siapana, el stock de Payandé, y con unidades volcánicas como el Volcánico de La Malena, las Vulcanitas de Segovia y Chaparral. Con esta correlación se separan unidades que estaban asociadas al batolito de Ibagué que afloran en una posición más oriental, definidas como los cinturones de plutones del carbonífero, Pérmico y Jurásico temprano a medio.

Abstract New fieldwork, pétrographie, geochemical, and zircon U-Pb geochronologic data allow us to identify new units and redefine the limits of the Ibagué batholith. The Ibagué batholith, located to the north of the Ibagué Fault, was divided into two geological units: the Anzoátegui Metatonalite (~194.7 km2) and Ibagué Tonalité (~278 km2). To the south of the Ibagué fault, the name Ibagué batholith is maintained, but its original extension changes to ~3200 km2 due to theoccurrence of the Carboniferous Belalcázar and Los Guayabos gabbros, the Permian Ortega and La Plata granites, and the early Jurassic Páez quartz-monzodiorite. The Anzoátegui Metatonalite and Ibagué Tonalite are composed of calc-alkaline and metaluminous metatonalites, tonalites, and granodiorites, yielding U-Pb crystallization ages between 158.2+1.2/-0.4 and 150.17±0.86 Ma, and between 145.71+0.72/-1.42 Ma and 138.48±0.95 Ma, respectively. The Ibagué batholith is constituted by calc-alkaline to high K calc-alkaline, metaluminous and peraluminous, tonalites, granodiorites, and monzogranites, yielding crystallization ages between 171.5±1.3 and 137.9±1.0 Ma. The Ibagué batholith, the Anzoátegui Metatonalite, and the Ibagué Tonalite are calcic granitoids generated in an arc environment, presenting Nb, Ti, and P negative anomalies. The geotectonic position, petrographic and geochemical composition, and crystallization ages allowed us to correlate the Ibagué batholith, the Anzoátegui Metatonalite, and the Ibagué Tonalite with the Segovia and Los Alisales batholiths, the Siapana granodiorite, the Payandé stock, and volcanic units such as the La Malena volcanic rocks, the Segovia and Chaparral vulcanites. This correlation also drives the separation of the Ibagué batolith from other units like the Carboniferous, Permian, and Early to Middle Jurassic plutons cropping out further east.

Abstract The article aims to present a model proposal to favor the inclusion of migrant students in primary schools with Catholic identity, located in vulnerable sectors of Chile. An action-research design was used as methodology. In a first phase, the inclusion status of migrant students in schools in the Santiago and Antofagasta regions was diagnosed. In the second, the model was developed and validated by 18 expert peers. A third phase of piloting the validated model is contemplated. The main result of the first two phases was a Spiral Reflection Model that raises questions around three main aspects: organizational, curricular and pedagogical, through which an educational institution can question its work and advance in a permanent reflective process that allows to define actions that strengthen the inclusion of migrant students, promoting essential principles of catholicity.

Resumen El artículo tiene como objetivo presentar una propuesta de modelo para favorecer la inclusión de estudiantes migrantes en escuelas básicas (primarias) de identidad católica, ubicadas en sectores vulnerables en Chile. Se utilizó como metodología un diseño de investigación-acción. En una primera fase se diagnosticó el estado de la inclusión de estudiantes migrantes en escuelas de las regiones de Santiago y Antofagasta. En la segunda, se elaboró el modelo y se realizó su validación por 18 pares expertos. Se contempla una tercera fase de pilotaje del modelo validado. El principal resultado de las primeras dos fases fue un Modelo Espiral de Reflexión que plantea preguntas en torno a tres ejes: organizacional, curricular y pedagógico, mediante las cuales un establecimiento educativo puede interrogarse respecto de su trabajo y avanzar en un proceso reflexivo permanente que le permita definir acciones para fortalecer la inclusión de estudiantes migrantes, promoviendo principios esenciales de catolicidad.

Resumo Objetivo Existem poucos estudos multinacionais sobre os resultados do tratamento da neoplasia trofoblástica gestacional (NTG) na América do Sul. O objetivo deste estudo foi avaliar a apresentação clínica, os resultados do tratamento e os fatores associados a casos de quimiorresistência em NTG pós-molar de baixo risco tratados com quimioterapia de agente único de primeira linha em três centros sul-americanos. Métodos Estudo multicêntrico de coorte histórica incluindo mulheres com NTG pós-molar de baixo risco com estadiamento International Federation of Gynecology and Obstetrics (FIGO) em centros de atendimento na Argentina, Brasil e Colômbia entre 1990 e 2014. Foram obtidos dados sobre as características do paciente, apresentação da doença e resposta ao tratamento. A regressão logística foi usada para avaliar a relação entre fatores clínicos e resistência ao tratamento de primeira linha com agente único. Foi realizada uma análise multivariada dos fatores clínicos significativos na análise univariada. Resultados Cento e sessenta e três mulheres com NTG de baixo risco foram incluídas na análise. A taxa global de resposta completa à quimioterapia de primeira linha foi de 80% (130/163). As taxas de resposta completa ao metotrexato ou actinomicina-D como tratamento de primeira linha e actinomicina-D como tratamento de segunda linha após falha do metotrexato foram 79% (125/157), 83% (⅚) e 70% (23/33), respectivamente. A mudança para o tratamento de segunda linha por quimiorresistência ocorreu em 20,2% dos casos (33/163). A análise multivariada demonstrou que pacientes com pontuação de risco FIGO de 5 a 6 foram 4,2 vezes mais propensos a desenvolver resistência ao tratamento com agente único de primeira linha (p= 0,019). Conclusão 1) Na apresentação, a maioria das mulheres demonstrou características clínicas favoráveis a um bom resultado, 2) a taxa geral de remissão completa sustentada após o tratamento de primeira linha com agente único foi comparável à de países desenvolvidos, 3) um escore de risco FIGO de 5 ou 6 está associado ao desenvolvimento de resistência à quimioterapia de agente único de primeira linha.

Abstract Objective There are few multinational studies on gestational trophoblastic neoplasia (GTN) treatment outcomes in South America. The purpose of this study was to assess the clinical presentation, treatment outcomes, and factors associated with chemoresistance in low-risk postmolar GTN treated with first-line single-agent chemotherapy in three South American centers. Methods Multicentric, historical cohort study including women with International Federation of Gynecology and Obstetrics (FIGO)-staged low-risk postmolar GTN attending centers in Argentina, Brazil, and Colombia between 1990 and 2014. Data were obtained on patient characteristics, disease presentation, and treatment response. Logistic regression was used to assess the relationship between clinical factors and resistance to first-line single-agent treatment. A multivariate analysis of the clinical factors significant in univariate analysis was performed. Results A total of 163 women with low-risk GTN were included in the analysis. The overall rate of complete response to first-line chemotherapy was 80% (130/163). The rates of complete response to methotrexate or actinomycin-D as first-line treatment, and actinomycin-D as second-line treatment postmethotrexate failure were 79% (125/157), 83% (⅚), and 70% (23/33), respectively. Switching to second-line treatment due to chemoresistance occurred in 20.2% of cases (33/163). The multivariate analysis demonstrated that patients with a 5 to 6 FIGO risk score were 4.2-fold more likely to develop resistance to first-line single-agent treatment (p= 0.019). Conclusion 1) At presentation, most women showed clinical characteristics favorable to a good outcome, 2) the overall rate of sustained complete remission after first-line single-agent treatment was comparable to that observed in developed countries, 3) a FIGO risk score of 5 or 6 is associated with development of resistance to first-line single-agent chemotherapy.

Resumen Los colorantes sintéticos son estables, ofrecen una amplia gama de colores y fáciles aplicaciones industriales. Sin embargo, en ambientes acuosos representan un problema por su larga permanencia y baja biodegradabilidad. Los hongos de podredumbre blanca pueden degradar colorantes a través de sus enzimas ligninolíticas y/o biosorción. Este trabajo evaluó el efecto de 2,5-dimetilanilina, glucosa, tartrato de amonio, sulfato de cobre, pH y temperatura sobre la degradación del colorante azul turquesa (TB) en soluciones acuosas por Leptosphaerulina sp. (hongo nativo de Colombia). Los ensayos se desarrollaron aplicando un diseno experimental de superficie de respuesta, que encontró al tartrato de amonio y el pH como las variables más infuyentes para remover el TB. Leptosphaerulina sp. elimina el TB (99%, día 8), principalmente por sorción (89%). Por lo tanto, la biomasa de Leptosphaerulina sp. es una alternativa promisoria como biosorbente, frente a los métodos tradicionales físico-químicos, para tratar aguas residuales contaminadas con colorantes.

Abstract Synthetic dyes are highly stable, offer a wide range of colors, and have easy industrial applications. Nevertheless, dyes become a problem in aqueous environments due to their long permanence and low biodegradability. White-rot fungi are useful to degrade dyes through their ligninolytic enzymes and/or biosorption. This work evaluated the effect of 2,5-dimethylaniline, glucose, ammonium tartrate, copper sulfate, pH, and temperature on the degradation of Turquoise Blue (TB) dye in aqueous solutions by Leptosphaerulina sp. (Colombian native fungus). Assays were developed applying a response surface experimental design, which found that the ammonium tartrate and pH are the most influential variables on TB removal. Leptosphaerulina sp. decolorizes aqueous solutions with TB (99%, at day 8), mainly through sorption (89%). Therefore, one of the significant findings from this study is that the Leptosphaerulina sp. biomass is a promising alternative as biosorbent, in comparison to physical-chemical traditional methods, for treating wastewaters polluted with dyes.

Abstract. The objective of this study was to stablish the prevalence of psychoactive substances consumption among students and to associate this consumption with the socio-demographic, family structures, and personality traits. The study was set on a public technological institute of Medellin, Colombia during 2016. The next tests were applied once to the students: ASSIT, APGAR Family, NEO-FFI, ERI and a test of sociodemographic variables. The primary outcome in this study was the prevalence of consumption of psychoactive substances among students. In order to stablish the association between psychoactive substances and sociodemographic, family structures, and personality traits, a logistic regression model was fit. A total of 891 students participated in this study. The prevalence of psychoactive substances use among students was 51.6%. The logistic regression conducted on the data proved that males, among 18 to 24 years, with intrafamily deficit, and with low kindness were positively associated with greater PAS use (OR = 2.97, 2.72, 1.63, 9.32, respectively). Kindness aspects (e.g., confidence, frankness, counseling, sensitivity to others) and family relationships should be improved in order to prevent psychoactive substances use among students.

Resumen. El objetivo del estudio fue determinar la prevalencia del consumo de sustancias psicoactivas y los factores asociados con las caracteristicas sociodemográficas, familiares y de personalidad. El estudio se realizó en un Instituto de formación tecnológica de carácter público Medellin, 2016. La muestra estuvo conformada por 891 estudiantes a quienes se les aplicó los instrumentos ASSIT, APGAR Familiar, NEO-FFI, ERI y un cuestionario de variables sociodemográficas. Los resultados mostraron que la prevalencia de consumo de sustancias psicoactivas fue de 51,6%; con mayor consumo de alcohol (49,7%). La prueba de regresión logistica sugiere que ser hombre (OR= 2,97), con edad entre 18 y 24 años (OR= 2,72), con expresión en estado bajo en las relaciones intrafamiliares (OR= 1,63) y prestar un nivel muy bajo en amabilidad (Or=9,32) se asocia de forma negativa con el consumo de sustancias psicoactivas. Se resalta la importancia de fortalecer aspectos de la personalidad relacionados con la amabilidad (confianza, franqueza, actitud conciliadora, sensibilidad a los demás), además de las relaciones intrafamiliares y aspectos que faciliten prevenir el consumo de sustancias psicoactivas en los estudiantes.

Resumen El presente artículo analiza la dinámica del conflicto armado entre el Estado colombiano y el Bloque Caribe de las Fuerzas Armadas Revolucionarias de Colombia - Ejército del Pueblo (FARC-EP) en el periodo de la política de Seguridad Democrática (2002-2010). Mediante un análisis comparado de las tres subregiones en donde hacía presencia mayoritariamente esta guerrilla en la Costa Caribe -Montes de María, Sierra Nevada de Santa Marta y Serranía del Perijá-, se observan las acciones de ambas partes con el fin de indagar las razones por las cuales el Estado tuvo un mayor éxito en la subregión montemariana en relación con las otras dos zonas. Se concluye que las características geoestratégicas de Montes de María llevaron a que el Estado tuviera acciones militares e integrales más intensas, las cuales tuvieron como resultado la temprana desarticulación de las estructuras farianas que allí operaban. Por su parte, los frentes que hacían presencia en la Sierra Nevada de Santa Marta fueron desplazados a la Serranía del Perijá tan solo al finalizar el periodo de estudio, manteniendo la actividad del bloque en esta zona fronteriza.

Abstract This article analyzes the dynamics of the armed conflict between the Colombian State and the Caribbean Bloc of the Revolutionary Armed Forces of Colombia - People's Army (FARC-EP) over the period of the Democratic Security policy (2002-2010). Through a comparative analysis of the three subregions where this guerrilla had a prominent presence on the Caribbean Coast -Montes de María, Sierra Nevada de Santa Marta and Serranía del Perijá-, the actions of both sides were observed in order to investigate the reasons why the State had greater success in the Montemarian subregion as compared to the other two areas. The conclusion is that the geostrategic characteristics of Montes de María led the State to have more intensive military and comprehensive actions, which resulted in the early dismantling of the Farian structures that were operating there. In turn, the Fronts that were present in the Sierra Nevada de Santa Marta were moved to the Serranía del Perijá only at the end of the research period, maintaining the activity of the Bloc in this border area.

Resumo Este artigo analisa a dinâmica do conflito armado entre o Estado colombiano e o Bloco Caribenho das Forças Armadas Revolucionárias da Colômbia - Exército Popular (FARC-EP) no período da Política de Segurança Democrática (2002-2010). Através de uma análise comparativa das três sub-regiões onde esta guerrilha esteve presente principalmente na costa do Caribe -Montes de Maria, Sierra Nevada de Santa Marta e Serranía del Perijá-, observam-se as ações de ambas as partes a fim de investigar as razões pelas quais o Estado teve maior sucesso na sub-região de Montes de Maria em relação às outras duas zonas. Conclui-se que as características geoestratégicas da região Montes de Maria levaram o Estado a ter ações militares mais intensas e integrais, o que resultou no desmante lamento precoce das estruturas das FARC que ali funcionavam. Por sua vez, as frentes que estavam presentes na Sierra Nevada de Santa Marta foram deslocadas para a Serranía del Perijá apenas no final do período de estudo, mantendo a atividade do bloco nesta zona fronteiriça.
