Reproductive performance of genetically engineered mice housed in different housing systems / 한국실험동물학회지

The genetically engineered mice require special husbandry care and are mainly housed in Individually Ventilated Cage (IVC) systems and Static Micro Isolator Cages (SMIC) to minimize the risk for spreading undesirable microorganisms. However, the static micro isolation cage housing like SMIC are being replaced with IVC systems in many facilities due to a number of benefits like a higher density housing in limited space, better protection from biohazards and allergens and decreased work load due to decreased frequency of cage changing required in this system. The purpose of this study was to examine the reproductive performance of genetically engineered mice housed in individually ventilated cages (IVC) and Static Micro Isolator Cages (SMIC). When the B6C3-Tg (APPswe, PSEN1dE9) 85Dbo/Mmjax transgenic mice were housed in these two housing systems, the number of litters per dam, number of pups born per dam and number of pups weaned per dam were found to be slightly higher in the IVC as compared to the SMIC but the difference was not significant (P<0.05). In case of Growth Associated Protein 43 (GAP-43) knockout mice, the number of litters born per dam and the number of pups born per dam were marginally higher in the IVC as compared to those housed in SMIC but the difference was not significant (P<0.05). Only the number of pups weaned per dam were found to be significantly higher as compared to those housed in the SMIC system at P<0.05.

Processos de subjetivação no contexto da monocultura de cana-de-açúcar / Process of subjectivation in the context of sugar cane monoculture / Procesos de subjetivación en el contexto del monocultivo de la caña de azúcar

Este artigo resulta de pesquisa realizada em uma comunidade situada geograficamente na propriedade de uma usina sucroalcooleira do Estado de Alagoas, Nordeste do Brasil. O objetivo principal do estudo é discutir os processos de subjetivação de sujeitos que moram e trabalham nesse território. Realizamos entrevistas não estruturadas com moradores, roda de conversa com trabalhadores da usina, visitas à comunidade e registros em diários de campo. Utilizamos o referencial teórico de Michel Foucault para discutir os processos de subjetivação no contexto em estudo. A pesquisa nos permitiu visibilizar diferentes vetores de subjetivação que constituem a vida no cotidiano da comunidade e compõem as formas de existência desses sujeitos. Destacamos, entre esses, a separação entre o que chamam de vida "na usina" e vida "lá fora", as relações com o trabalho, a violência e a religião

This article resulted from research conducted in a community geographically located on the property of a sugar and alcohol plant in the state of Alagoas, northeastern of Brazil. The main objective of the study is to discuss the processes of subjectivation of subjects who live and work in this territory. We conducted unstructured interviews with residents, group discussions with plant workers, community visits and records in field diaries. We used the theoretical framework of Michel Foucault to discuss the process of subjectivation in the context under study. The research allowed us to visualize different vectors of subjectivation that constitute everyday life in the community and compose forms of existence of these subjects. We highlight, among these, the separation between what they call life "at the plant" and life "out there", relations with labor, violence and religion

Este artículo resulta de una investigación realizada en una comunidad geográficamente ubicada en la propiedad de una planta sucro-alcoholera en el estado de Alagoas, al nordeste de Brasil. El objetivo principal del estudio es discutir los procesos de subjetivación de las personas que viven y trabajan en ese territorio. Realizamos entrevistas no estructuradas con los residentes, ruedas de conversaciones con trabajadores de la planta, visitas a la comunidad y registros en diarios de campo. Utilizamos el marco teórico de Michel Foucault para discutir los procesos de subjetivación en el contexto estudiado. El estudio nos permitió visualizar diferentes vectores de subjetivación que constituyen la vida cotidiana en la comunidad y que componen las formas de existencia de estos sujetos. Destacamos, entre ellas, la separación entre lo que llaman la vida "en la planta" y la vida "allá afuera", las relaciones con el trabajo, la violencia y la religión
