Participación comunitaria y procesos de comunicación en la implementación de programas de reasentamiento de familias dentro del contexto del desarrollo urbano en Barranquilla (Colombia)

Planning processes of development and growth of the city of Barranquilla have required the relocation of the population living in areas of intervention actions. As part of the implementation of the New Management Plan Territorial (POT), the city plans to revitalize an area around the Magdalena River with a view to improving the quality of life of citizens and to increase competitiveness of the city. The revitalization project is known as project “La Loma “. Under the current Land Use Plan of Barranquilla (POT), the urban development project “La Loma” includes, among other activities, the transfer of a large number of people currently living in this area. For this reason, this article aims to review the current POT and documents from City Council and the Mayor’s office associated with the POT and “La Loma” project, in order to identify and analyze the component of community participation and communication related to the implementation of this project. The results of the documents revealed the presence of regulatory elements associated with community participation. The results also showed potentially useful spaces for the implementation of inclusive communication processes. Therefore, this article proposes a guide for the formulation of a strategic communication plan with a focus on participatory communication and dialogue facilitator to be used during the execution of urban projects that include the relocation of families. © 2016, Universidad del Norte.

Estudio preliminar sobre una posible inhibición dopaminérgia en la reproducción del lenguado senegalés (Solea senegalensis)

El objetivo del presente estudio fue evaluar el efecto del sistema dopaminérgico sobre la reproducción del lenguado senegalés (Solea senegalensis). Para ello, reproductores de lenguado senegalés nacidos y criados en cautividad (generación F1) fueron tratados con 1) GnRHa, 2) inhibidor dopaminérgico (pimozide) o 3) un tratamiento combinado (GnRHa + pimozide). El efecto de los tratamientos se evaluó a nivel de producción de huevos y esperma (cantidad y calidad); además se estudió el efecto sobre niveles plasmáticos de esteroides sexuales y desarrollo gonadal (histología). Las hembras no mostraron una estimulación en la ocurrencia de puestas por el tratamiento combinado GnRHa + pimozide respecto a aquellas tratadas solo con GnRHa. Sin embargo, los machos que recibieron el tratamiento combinado mostraron una mayor estimulación en la producción de esperma y en el grado de maduración testicular respecto a aquellos que recibieron solo GnRHa o pimozide. Los resultados indican que el sistema dopaminérgico no parece ejercer una acción fuerte sobre la ocurrencia de puestas en hembras, aunque podría estimular la espermiación en machos de lenguado senegalés.Preliminary study on dopaminergic inhibition in Senegalese sole reproduction (Solea senegalensis) The aim of the present study was to evaluate the effect of the dopaminergic system on Senegalese sole (Solea senegalensis) reproduction. For this purpose, Senegalese sole breeders hatched and raised in captivity (F1 generation) were treated with 1) GnRHa, 2) a well-known dopaminergic inhibitor (pimozide) or 3) a combined treatment (GnRHa + pimozide). The effect of each treatment was determined by studying spawning occurrence and sperm (quantity and quality); in addition, effects on sex steroids levels and on gonadal development (histology) were also considered. Females did not show any improvement of spawning occurrence by combining GnRHa and pimozide respect to those females treated only with GnRHa. However, males which received the combined treatment showed a greater stimulation of sperm production and testicular maturity than those males treated with a single GnRHa or pimozide treatment. Our results indicate that dopaminergic system do not seem to play a strong action on eggs spawning in females, but may stimulate spermiation in Senegalese sole males

Balantidium spp en cerdos y sus criadores: Prevalencia en comunidades de dos Estados de Venezuela.

Balantidium coli is the only ciliated protozoan that infects humans. It can also infect pigs, these can also be infected by B. suis. which is morphologically identical to B. coli.. It has been suggested that pigs are the source for human infections, even though this remains controversial. To determine Balantidium spp prevalence in pigs and humans, we evaluated 51 pig farmers and 72 pigs: 60 farm-raised and 12 domestically bred. The parasitological study was performed by direct examination, concentration methods, cultures and specific stains. Balantidium spp was identified in 65% and 67% of farm reared pigs and domestically raised pigs, respectively. We also detected other protozoa and helminths. There was no Balantidium spp infection in pigs keepers, so we suggested that B. suis appears to be prevalent in these animals.Balantidium coli , es el único protozoario ciliado que parasita al hombre. Infecta diferentes animales, entre ellos al cerdo, el cual además es infectado por B. suis que es morfológicamente idéntico. Se plantea que el cerdo es la fuente de infección para el humano, existiendo controversias al respecto. Para determinar la prevalencia de Balantidium spp en cerdos y humanos, se estudiaron 72 cerdos, 60 criados en granjas, 12 criados domésticamente y 51 personas que los manipulaban. El estudio parasitológico se realizó mediante examen microscópico directo, métodos de concentración, cultivos y coloraciones especiales. Balantidium spp se identificó en 65% y 67% de los cerdos criados en granjas y domésticamente, respectivamente. También se detectó otros protozoarios y helmintos. No se encontró infección con Balantidium spp en los criadores de cerdos, sugiriendo que B. suis podría ser la especie que prevalece en este grupo de animales examinados
