RESUMO

Probiotics have gained significant attention in recent years due to the growing awareness of physical health and well-being. However, maintaining high concentrations of probiotics throughout the product's shelf life and during the gastrointestinal tract is crucial for ensuring their health-promoting effects. After determining an optimal formulation through a fractional factorial model, this study optimizes probiotic Bacillus Clausii delivery through spray-drying microencapsulation using a novel maltodextrin-alginate-inulin (MDX-ALG-IN) formulation (optimized ratio: 7:2:1). Notably, this formulation exclusively comprises non-digestible carbohydrates, marking a novel approach in probiotic encapsulation. Achieving a high Product Yield (51.06 %) and Encapsulation Efficiency (80.53 %), the study employed SEM for morphological analysis, revealing an irregular form and extensive surface in dentations characteristic of maltodextrin involvement. With a low moisture content of 3.02 % (±0.23 %) and 90.52 % solubility, the powder displayed exceptional properties. Probiotic viability remained robust, surviving up to 60 % even after 180 days at 4 °C, 25 °C, and 37 °C. Thermal characterization unveiled microcapsule resilience, exhibiting a glass transition temperature (Tg) at 138.61 °C and a melting point of 177.28 °C. The study systematically addresses crucial aspects of microencapsulation, including formulation optimization, morphological characteristics, and powder properties. Notably, the MDX-ALG-IN microcapsules demonstrated stability in simulated gastrointestinal conditions, indicating potential application for supplements and complex food matrices. In summary, this research contributes to microencapsulation understanding, emphasizing the MDX-ALG-IN formulation's efficacy in preserving probiotic viability across production stages and simulated digestive processes.

RESUMO

Shark fishing, driven by the fin trade, is the primary cause of global shark population declines. Here, we present a case study that exemplifies how industrial fisheries are likely depleting shark populations in the Eastern Tropical Pacific Ocean. In August 2017, the vessel Fu Yuan Yu Leng 999, of Chinese flag, was detained while crossing through the Galápagos Marine Reserve without authorization. This vessel contained 7639 sharks, representing one of the largest seizures recorded to date. Based on a sample of 929 individuals (12%), we found 12 shark species: 9 considered as Vulnerable or higher risk by the IUCN and 8 listed in CITES. Four species showed a higher proportion of immature than mature individuals, whereas size-distribution hints that at least some of the fishing ships associated with the operation may have been using purse-seine gear fishing equipment, which, for some species, goes against international conventions. Our data expose the magnitude of the threat that fishing industries and illegal trade represent to sharks in the Eastern Tropical Pacific Ocean.

RESUMO

Hypercoagulable state is linked to cancer progression; however, the precise role of the coagulation cascade is poorly described. Herein, we examined the contribution of a hypercoagulative state through the administration of intravenous Coagulation Factor Xa (FXa), on the growth of solid human tumors and the experimental metastasis of the B16F10 melanoma in mouse models. FXa increased solid tumor volume and lung, liver, kidney and lymph node metastasis of tail-vein injected B16F10 cells. Concentrating on the metastasis model, upon coadministration of the anticoagulant Dalteparin, lung metastasis was significantly reduced, and no metastasis was observed in other organs. FXa did not directly alter proliferation, migration or invasion of cancer cells in vitro. Alternatively, FXa upon endothelial cells promoted cytoskeleton contraction, disrupted membrane VE-Cadherin pattern, heightened endothelial-hyperpermeability, increased inflammatory adhesion molecules and enhanced B16F10 adhesion under flow conditions. Microarray analysis of endothelial cells treated with FXa demonstrated elevated expression of inflammatory transcripts. Accordingly, FXa treatment increased immune cell infiltration in mouse lungs, an effect reduced by dalteparin. Taken together, our results suggest that FXa increases B16F10 metastasis via endothelial cell activation and enhanced cancer cell-endothelium adhesion advocating that the coagulation system is not merely a bystander in the process of cancer metastasis.

RESUMO

Abstract Aim: To describe characteristics of alcohol consumption and to identify patterns of consumption among dental students from University San Sebastián, Concepción. Method: This is an exploratory, non-experimental, descriptive and cross sectional study with a sample of 601 students (65 % of students). Two questionnaires were applied during the second semester of 2015. The first: A structured questionnaire designed to collect data on alcohol consumption and its characteristics. The second: the Alcohol Use Disorders Identification Test. The data was analyzed using descriptive statistics. The association of the dependent variable "alcohol" with the independent variables "age", " gender", "geographic location of origin" and "semester" were evaluated by a binomial logistic regression. Then, the data observed in subjects who reported drinking alcohol were evaluated. The significance level used in all cases was a<0.05. Results: 15 % is a risk consumer, and 18% is a harmful consumer or have a possible dependence. In students who drink, the variable family income is associated with the time of year of consumption and alcohol-related problems. Conclusion: There is a higher prevalence of male consumption and a high consumption of alcoholic beverages in both genders at any time of the year. Consumption of alcoholic beverages is independent of family income.


Resumen Objetivo: Describir características del consumo de bebidas alcohólicas e identificar patrón de consumo en estudiantes de odontología de la Universidad San Sebastián, sede Concepción. Materiales y métodos: Estudio exploratorio, descriptivo, transversal, no experimental. La muestra estuvo constituida por 601 alumnos (65% del total). Se aplicaron dos cuestionarios durante el segundo semestre del año 2015. El primero: cuestionario estructurado diseñado para recolectar datos sobre el consumo de alcohol y sus características. El segundo: cuestionario autoadministrado de"Identificación de Trastornos Relacionados con el Consumo de Alcohol". Los datos fueron analizados mediante estadígrafos descriptivos. La asociación de la variable dependiente "alcohol" con las variables independientes "edad", "género", "ubicacióngeográfica de origen" y "semestreacadémico" fueron evaluados mediante una prueba de regresión logística binomial. Sólo los datos de los sujetos que consumían alcohol fueron evaluados. El nivel de significación empleado en todos los casos fue de a<0,05. Resultados: El 15% de los estudiantes es consumidor de riesgo y 18% presenta consumo perjudicial o posible dependencia. En estudiantes que consumen alcohol, la variable ingreso familiar, en relación con las variables época del año en que consumen y la presencia de problemas derivados del alcohol, están asociadas. Conclusión: Existe mayor prevalencia de consumo en el género masculino y un alto consumo de bebidas alcohólicas en ambos géneros en cualquier época del año. El consumo de bebidas alcohólicas es independiente del ingreso familiar.

RESUMO

Abstract Introduction: The training of future dentists should consider developing empathy while they are still students. The first step to consider such training is to assess empathic behavior. Objective: To measure levels of empathy in dental students of Universidad San Sebastián in Concepción, by gender and academic year. Materials and methods: The Spanish version of the Jefferson Scale of Physician Empathy (JSPE) for medical students (S version) was adapted and validated for the dental students of Universidad San Sebastián (Concepción, Chile) in 2016. The sample consisted of 462 students from first to fifth year. The data was compared by a trifactorial variance analysis (Model III). Results: The "Academic Year" factor showed that the average in the second year is relatively lower than in the first. However, beginning in the third year, levels tend to increase and remain relatively constant for the next academic years. The "gender" factor revealed that women had higher average empathy values compared to males. Conclusion: The factors studied (academic year and gender) shortly explain the variation of empathy in the sample of students analyzed. There are probably other factors that influence levels of empathy and that would explain better the behavior of estimated values of empathy.


Resumen Introducción. La formación de los futuros odontólogos debe estar en sintonía con el desarrollo empático del alumno, por tanto, es necesario realizar un diagnóstico del comportamiento de la empatia. Objetivo. Medir los niveles de empatia en los estudiantes de Odontología de la Universidad San Sebastián, sede Concepción, Chile, según género y año académico. Materiales y métodos. Se aplicó la Escala de Empatia Médica de Jefferson (EEMJ) para estudiantes de medicina (versión en español), adaptada y validada para estudiantes de odontología en 2016. La muestra estuvo constituida por 462 estudiantes de primero a quinto año. Los datos fueron comparados mediante un análisis de varianza trifactorial (modelo III). Resultados. En el factor "años académicos" se observó que las medias en el segundo año son menores que en el primero, pero a partir de tercer año aumentan los niveles de empatía manteniéndose constantes en los restantes años académicos. En el factor "género", el femenino tuvo valores medios de empatía superiores al masculino. Conclusión. Los factores estudiados (año académico y género) poco explican la variación existente en la empatía de los estudiantes analizados. Es probable que existan otros factores que influyen sobre los niveles de empatia y que permitirían explicar mejor el comportamiento de los valores estimados.

RESUMO

Dendritic cells (DCs) display the unique ability for cross-presenting antigens to CD8+ T-cells, promoting their differentiation into cytotoxic T-lymphocytes (CTLs), which play a pivotal role in anti-tumor immunity. Emerging evidence points to dopamine receptor D3 (D3R) as a key regulator of immunity. Accordingly, we studied how D3R regulates DCs function in anti-tumor immunity. The results show that D3R-deficiency in DCs enhanced expansion of CTLs in vivo and induced stronger anti-tumor immunity. Co-culture experiments indicated that D3R-inhibition in DCs potentiated antigen cross-presentation and CTLs activation. Our findings suggest that D3R in DCs constitutes a new therapeutic target to strengthen anti-tumor immunity.

RESUMO

Introducción: La erupción cronológica de los dientes deciduos y permanentes implica una serie de procesos sucedáneos que van desde la morfogénesis de cada diente hasta el establecimiento fisiológico de la oclusión dental. Sin embargo, se ha identificado que diferentes factores genéticos y medioambientales locales y regionales pueden alterar el proceso secuencial de erupción de los dientes respecto a la edad cronológica de los seres humanos. Objetivo: Caracterizar la cronología de la erupción dentaria en un grupo de mestizos caucasoides de Cali (Colombia). Materiales y Métodos: Estudio descriptivo observacional de corte transversal que determinó el dimorfismo sexual, la simetría de arco y la simetría bilateral a partir de la observación y análisis de la cronología de la erupción dentaria en 355 radiografías panorámicas pertenecientes a un grupo de mestizos caucasoides (181 de individuos femeninos y 174 de masculinos) de la ciudad de Cali (Colombia) a través del método de Schour y Massler. Resultados: Al correlacionar la edad cronológica con la edad radiográfica, no se evidenciaron diferencias entre sexo, arco y lado en la cronología de erupción de los dientes deciduos y permanentes. Conclusiones: El método de Schour y Massler permitió evidenciar una alta correlación entre la edad dental y la edad cronológica, lo cual es de gran utilidad en el contexto clínico odontológico para hacer seguimiento de la salud buco-dento-maxilo- facial en armonía con el crecimiento y desarrollo postnatal, y en el contexto antropológico y forense para para la estimación de la edad como parte de la cuarteta básica de identificación y para la documentación de los dictámenes médicolegales de edad.


Background: The chronological eruption of the deciduous and permanent teeth involves a sequential process that go from the morphogenesis of each tooth to the physiological establishment of the dental occlusion. However, it has been identified that different local and regional genetic and environmental factors can alter the sequential process of eruption of the teeth with respect to the chronological age of human beings. Objective: Characterize the chronology of tooth eruption in a group of Caucasoid mestizos from Cali (Colombia). Materials and Methods: Cross-sectional study that determined sexual dimorphism, arch symmetry and bilateral symmetry from the observation and analysis of the chronology of tooth eruption in 355 panoramic radiographs belonging to a group of Caucasoid mestizos (181 female and 174 men individuals) from the city of Cali (Colombia) through the method of Schour and Massler. Results: When correlating chronological age with radiographic age, no differences between sex, arch and side in the chronology of eruption of the deciduous and permanent teeth were found. Conclusions: The Schour and Massler method showed a high correlation between dental age and chronological age, which is very useful in the dental clinical context to monitor the oral-maxillofacial health in harmony with postnatal growth and development, and in the anthropological and forensic context for the estimation of age as part of the basic identification proceedings and for the documentation of medical-legal age opinion.

RESUMO

AbstractFish by-catch of shrimp fishery from the Gulf of Tehuantepec is composed of several species that are mainly discarded. In this study, fish by-catch species composition, distribution and biogeographical affinities were analyzed. For this, a total of 15 cruises were carried out on the continental shelf, at depths from 15 to 64 m, during 2003, 2004, 2005 and 2013. Results showed that fish by-catch was represented by 58 families, 129 genera and 242 species. The families Haemulidae, Sciaenidae, Paralichthyidae, Gerreidae and Carangidae accounted for > 70 % of the catch. Haemulopsis axillaris, Syacium ovale, Selene peruviana, Diapterus peruvianus, Larimus acclivins and Stellifer erycimba were the most frequent species at < 40 m depth (inner shelf), and Prionotus stephanophrys, Scorpaena russula, Porichthys analis and Synodus scituliceps were dominant at 40-60 m depth (outer shelf). Analysis of biogeographical affinities showed that 36.1 % of species had a wide distribution, from San Diego Province to the Panamic Province, while 13.2 % had a restricted distribution in the Mexican and Panamic Provinces. The ichthyofaunal composition was markedly influenced by the local environment and seasonal conditions. Rev. Biol. Trop. 64 (2): 683-700. Epub 2016 June 01.


ResumenEn la pesquería del camarón del Golfo de Tehuantepec un gran número de especies de peces se capturan como fauna de acompañamiento y son descartadas. La composición, distribución y afinidades biogeográficas de la ictiofauna acompañante del camarón fue analizada mediante 15 cruceros desarrollados en la plataforma continental entre 15-64 m de profundidad durante 2003, 2004, 2005 y 2013. La ictiofauna descartada estuvo representada por 58 familias, 129 géneros y 242 especies. Las familias, Haemulidae, Sciaenidae, Paralichthyidae, Gerreidae y Carangidae aportaron más del 70 % de la captura. Haemulopsis axillaris, Syacium ovale, Selene peruviana, Diapterus peruvianus, Larimus acclivins y Stellifer erycimba fueron las especies más frecuentes en profundidades menores de 40 m (plataforma interna), mientras que Prionotus stephanophrys, Scorpaena russula, Porichthys analis y Synodus scituliceps, fueron dominantes entre 40-60 m de profundidad (plataforma externa). El análisis de las afinidades biogeográficas mostró que el 36.1 % de las especies son de amplia distribución desde la provincia de San Diego a la Panámica, mientras que el 13.2 %, presentó una distribución restringida entre la provincia Mexicana y la Panámica. La composición de la ictiofauna estuvo marcadamente influenciada por las condiciones ambientales locales y sus variaciones estacionales.

RESUMO

Strong and predictable environmental variability can reward flexible behaviors among animals. We used long-term records of activity data that cover several lunar cycles to investigate whether behavior at-sea of swallow-tailed gulls Creagrus furcatus, a nocturnal pelagic seabird, varied with lunar phase in the Galápagos Islands. A Bayesian hierarchical model showed that nighttime at-sea activity of 37 breeding swallow-tailed gulls was clearly associated with changes in moon phase. Proportion of nighttime spent on water was highest during darker periods of the lunar cycle, coinciding with the cycle of the diel vertical migration (DVM) that brings prey to the sea surface at night. Our data show that at-sea behavior of a tropical seabird can vary with environmental changes, including lunar phase.

RESUMO

We analyzed 30 study protocols of 30 patients that underwent sling procedure surgery for recurring urinary incontinence correction, from December 1993 up to November 1998. A double technique surgical with double equipment technique was performed (both vaginal and abdominal), using mersilene. Five patients were excluded because a lack of follow-up, which was planned for the first, third, six, twelve and 24 months after surgery. Twenty-one patients (84%) remained continent, four patients (16%) had persistent stress incontinence. One required reoperation for relief of persistent urinary retention secondary to over correction of urethra. We believe that patient selection is the most important factor to be considered in order to perform this technique because of the high morbility rate.

RESUMO

Tumors with stromal or sex-cords origin are scarce, and comprise only 5% or less of all ovarian tumors. Nevertheless functional tumor types are the most striking ones, only few of them produce hormonal symptoms. Fibrothecal tumors belong to the stromal cells tumor class, with differentiation towards both fibroblastic-type cells of thecal cell. We present a case report of a 68 years old woman with an ovarian tumor sized 14 x 9 x 7 cm. The treatment was the extirpation of the tumor. Microscopic evaluation of the surgical piece reported an ovarian fibrothecal tumor.

RESUMO

Se presentan dos casos de edema masivo bilateral de ovario, ocurridos en un hospital de concentración en los últimos cinco años. Se trata de una patología poco frecuente que afecta a mujeres jóvenes y fue descrita inicialmente por Kalstone en 1969. Este problema, puede ser uni o bilateral, este último, es poco frecuente y hasta el momento de la revisión se habían descrito diez casos en la literatura mundial. Los síntomas principales son: dolor y distensión abdominal, alteraciones menstruales, tumoración anexial y esterilidad. Una característica de esta patología es el rápido crecimiento del tamaño y volumen de los ovarios en corto tiempo. Desde el punto de vista histopatológico del dato principal es la presencia de edema intenso del estroma ovárico particularmente en la médula, sin detectarse elementos neoplásicos.El tratamiento habitual es la ooforectomía, aunque en casos bilaterales se ha sugerido la resección en cuña de ovarios con fijación de los mismos al útero para prevenir torciones ulteriores.Se concluye, que el edema masivo de ovario es una patología poco frecuente, que debe tenerse presente como causa de tumoración anexial y dolor abdominal en mujeres jóvenes con crecimiento rápido de la masa, en la cual no se identifican alteraciones neoplásicas.

RESUMO

La miomatosis uterina es menos frecuente en la mujer mayor, y sus características clínicas e histológicas en la posmenopausia tardía son desconocidas. Los miomas uterinos se confirmaron histológicamente en 14 de 69 pacientes (20.2 por ciento) de 65 años o mayores en quienes se realizó una histerectomía vaginal. Otro grupo con miomas fue pereado por edad con el grupo de estudio. En ambos grupos, el volumen uterino y los diámetros menores del útero fueron comparados, así como la edad de la menarca, menopausia y duración de la vida menstrual. El análisis estadístico se realizó por ANOVA. Se observó, como era esperado, que los volúmenes uterinos en las mujeres con miomatosis fueron significativamente mayores (p<0.01) que aquellos de las mujeres que no tuvieron miomas; sin embargo, el menor diámetro uterino no fue significativamente diferente entre ambos grupos, lo que es importante para el tratamiento quirúrgico de estas pacientes. Además, la vida menstrual de las pacientes con miomas fue significativamente mayor (p<0.04) que la de aquellas mujeres sin miomatosis. En conclusión, un quinto de las mujeres de 65 años de edad o mayores pueden presentar miomas y consecuentemente un incremento en el volumen uterino, pero sin incremento en los diámetros menores. Además, la mayor vida menstrual debe reconocerse como posible factor de riesgo para la presencia de miomatosis

RESUMO

Se revisaron 5,100 Biopsias realizadas en el Servicio de Anatomía Patológica en el lapso de noviembre de 1994 a noviembre de 1995, encontrando un total de 100 quistes paratubáricos. El 80 por ciento de los casos fue hallazgo quirúrgico el 40 por ciento de las pacientes tuvieron manifestaciones clínicas de dolor y 3 por ciento de las mismas abdomen agudo por torción del quiste que ameritó cirugía de urgencia. En 38 por ciento de los casos el informe ultrasonofráfico fue de Quistes de Ovario, y en 62 por ciento no fue detectado por este método. Con respecto al tamaño: 84 por ciento de los quistes paratubarios fueron menos de 6 cm, 12 por ciento entre 6 y 12 cm. y 4 por ciento de 12-18 cm. El informe Histopatológico fue quiste seroso (57 por ciento) y quiste simple (43 por ciento)
