Vitae , 2009,
Abstract: nowadays, antioxidants are compounds of great interest because they help positively to maintain human health. there is a marked interest in searching for antioxidants of natural sources, such as seaweed. for this reason extracts from five colombian seaweeds: caulerpa mexicana, laurencia sp., sargassum sp., dictyota sp. and sargassum cymosum are analyzed in this work. total phenolic content is determined using the folin-ciocalteau method and their antioxidant activity is determined by the ddph method. results show that all studied species of colombian seaweeds have an antioxidant activity possibly related with their total phenolic content. sargassum cymosum is the most active and it contains major phenolic compounds content. results show that marine colombian sources have a big potential for searching substances, with application in the pharmaceutics and alimentary sector.

Abstract: Los antioxidantes son compuestos de gran interés en la actualidad por sus benéficas implicaciones para la salud humana. Dado que en hoy existe un marcado interés en la búsqueda de antioxidantes de fuentes naturales, como las algas marinas, en este trabajo se analizan los extractos metanólico y hexánico de cinco macroalgas Colombianas: Caulerpa mexicana, Laurencia sp., Sargassum sp., Dictyota sp. y Sargassum cymosum. Se determina su contenido de compuestos fenólicos totales siguiendo el método de Folin-Ciocalteau, y se mide su actividad captadora de radicales libres mediante el método del DPPH de los respectivos extractos. Los resultados muestran que todas las especies de macroalgas Colombianas estudiadas presentan actividad antioxidante, posiblemente asociada a su contenido de fenoles totales. La especie Sargassum cymosum es la que ofrece mayor rendimiento en cuanto a contenido de compuestos fenólicos, actividad captadora de radicales libres, y es la segunda en rendimiento en cuanto al contenido de compuestos solubles en metanol. Se demuestra así que los recursos marinos Colombianos representan una gran potencial en la búsqueda de sustancias con aplicación en el sector farmacéutico y alimentario.

Abstract: the objective of this study is to understand the meanings of motherhood for different social actors (pregnant women and health personnel) within the prenatal care program of a health center in the city of popayán, colombia, a program developed as a strategy for the prevention and treatment of obstetric and perinatal complications. in order to uncover these meanings, a qualitative research study was carried out using interviews with social actors and observation of collective educational activities. discrepancies were observed among social actors about the meanings of motherhood, owing to the influence of biomedical knowledge and the differences in power relations, as well as to particular cultural referents. the lack of recognition of these discrepancies affects the program's capacity to respond to the needs and socio-cultural characteristics of the pregnant women it serves.
La comprensión de los significados de la maternidad: el caso de un programa de cuidado prenatal en un centro de salud en Popayán, Colombia

Salud Colectiva , 2011,
Abstract: El objetivo de este estudio es comprender los significados que sobre la maternidad tienen los actores sociales (mujeres embarazadas y personal de salud) dentro del programa prenatal de un centro de salud en la ciudad de Popayán, Colombia, programa implementado como estrategia para prevenir y manejar en forma oportuna las complicaciones obstétricas y perinatales. Para ello, se realizó una investigación cualitativa basada en entrevistas y observación de las actividades educativas colectivas. Entre los hallazgos, se encontraron discrepancias entre los actores sociales respecto de los significados de la maternidad, debido al conocimiento biomédico y a las relaciones de poder, aunque también vinculadas a los referentes culturales particulares. Estas discrepancias no reconocidas afectan la pertinencia del programa para responder a las necesidades y características socioculturales de las mujeres embarazadas.

An Assessment of the English Proficiency of the Thai Workforce and Its Implication for the ASEAN Economic Community: An Empirical Inquiry  [PDF]
Alexander Franco, Scott S. Roach
Open Journal of Business and Management (OJBM) , 2018, DOI: 10.4236/ojbm.2018.63050
Abstract:
The ten nation members of the Association of Southeast Asian Nations (ASEAN) utilize English as the official working language for the organization. This study focused on the nation of Thailand to examine the assessed level of English proficiency of its workforce in relation to its ability to interact within ASEAN’s economic community (AEC). This is the first academic study to utilize a sample population consisting of human resources personnel from the top 100 private companies in Thailand who are in charge of employee training for learning English. Self-administered questionnaires were used to obtain self-assessments on the issues of level of English proficiency, language training, resource allocation for communication preparedness in AEC, and overall perceptions of the importance of mastering English within their respective companies. The results indicate that the acquisition of English as an economic lingua franca was considered important regardless of the demographic factors of the company examined. A majority of the respondents expressed the belief that their businesses had provided adequate resource allocation for English preparedness and a majority also indicated that their respective workforces possessed adequate English skills. However, a majority also expressed assessments that the employees in their companies did not find it easy to learn English and that Thais in general, and their employees in particular, did not like learning the language.
Selective Posterior Epiphysiodesis of the Triradiate Cartilage of the Acetabulum: Preliminary Results of an Experimental Study in Rabbits  [PDF]

Open Journal of Orthopedics (OJO) , 2016, DOI: 10.4236/ojo.2016.68032
Abstract: Background: Residual acetabular dysplasia is one of the main complications of developmental dysplasia of the hip (DDH). Without treatment, over time degenerative osteoarthritis of the joint will develop, inexorably leading to the need for joint replacement. Acetabular and/or femoral osteotomies do not avoid the appearance of osteoarthritis in a significant number of patients. The purpose of this study was to assess the possibility of provoking changes in the morphology of the acetabulum through selective epiphysiodesis of the extra-articular portion of the ilioischial arm of the triradiate cartilage, using a percutaneous cannulated screw with the guidance of an imaging intensifier in an experimental model in rabbits. Methods: In a pilot study, 3-week-old New Zealand rabbits (n = 20) were submitted to unilateral surgery of the hip while the contralateral hip of the same group was used as a control. Posterior epiphysiodesis to the triradiate cartilage of the acetabulum was performed by placement of a cannulated screw. The rabbits were followed-up until 18 weeks of life. Radiographic measurements of the hips were performed immediately postoperatively and at 12 weeks of life and before the rabbits were sacrificed at week 18. Three-dimensional computed tomography (3D-CT) scans were performed. Non-parametric tests for paired samples and the Wilcoxon test were used to compare the differences between group 1 and group 2. A p < 0.05 was considered significant. Results: The non-intervened hips showed that, when the rabbit matured, the acetabulum lost concavity and depth. When comparing the median differences of the angles evaluated at 12 weeks between groups, a statistically significant difference was found in all radiographic measurements: an increase in Wiberg’s angle but a decrease in acetabular index, acetabular angle of Sharp, acetabular depth index, and acetabular anteversion. Evaluating the operated hips at 12 and 18 weeks (three months after having removed the screw) using 3D-CT, we observed a rebound effect in the correction confirming that the effect obtained through selective epiphysiodesis did not cause the definitive closure of the cartilage. Conclusions: Selective growth arrest of the ilioischial arm of the triradiate cartilage (posterior epiphysiodesis) can alter growth and change the shape of the acetabulum in rabbits. A rebound effect was observed when the screw was removed, confirming that the technique did not provoke definitive closure of the physis. Level of evidence: Level-2, therapeutic study.
