Cytogenetic characterization of Partamona cupira (Hymenoptera, Apidae) by fluorochromes

Four colonies of the stingless bee Partamona cupira (Hymenoptera: Apidae) were cytogenetically analyzed using conventional staining and the fluorochromes CMA3 e DAPI. The females have 2n = 34 chromosomes (2K = 32 M¯+2 A¯). Some females, however, presented an additional large B acrocentric chromosome, to a total of 2n = 35. Chromosome B and the chromosomal pairs 2, 9 and 10 showed CMA 3+ bands, indicating an excess of CG base-pairs. A clear association was verified between the P. helleri B chromosome SCAR marker and the presence of a B chromosome in P. cupira. The data obtained suggests that B chromosomes in P. helleri and P. cupira share a common origin

Sentimientos de adolescentes con Diabetes Mellitus delante del proceso de vivir con la enfermedad

Qualitative research conducted in a diabetes service in the countryside of the state of Ceará, Brazil, with 11 teenagers with diabetes mellitus. The study aimed to understand the experience of adolescents facing the process of living with diabetes. Data were collected in 2007 May and June, through semi-structured interviews. It was observed that the teenager faces difficulties since the moment of diagnosis, especially because their food habits and lifestyles need to change, triggering feelings like fear, insecurity and anger. Over time, they incorporate the necessary changes to treatment and care, and begin to see the disease as normal. One concludes that it is necessary to understand teenagers, their behaviors, fears and desires and support them in the different areas of this experience.Investigación cualitativa, llevada a cabo en un servicio de diabetes del interior del estado de Ceará, Brasil, con 11 adolescentes con diabetes mellitus. El objetivo fue comprender la experiencia del adolescente delante del proceso de vivir con diabetes. Los datos fueron recolectados entre mayo y junio de 2007 a través de entrevistas semi estructuradas. Se observó que el adolescente enfrenta dificultades desde el momento del diagnóstico, sobre todo en el plan alimentar y cambios en el estilo de vida, desencadenando sentimientos como miedo, inseguridad e ira. Con el tiempo, incorporan los cambios necesarios al tratamiento y atención, y llegan a ver la enfermedad como algo normal. En conclusión, que es necesario entender los adolescentes, sus comportamientos, miedos y deseos, y apoyarlos en las diferentes áreas de esta experiencia.Pesquisa de natureza qualitativa, realizada em um serviço de diabetes do interior do Ceará com 11 adolescentes portadores de diabetes mellitus.

The hidden world within plants: ecological and evolutionary considerations for defining functioning of microbial endophytes

All plants are inhabited internally by diverse microbial communities comprising bacterial, archaeal, fungal, and protistic taxa. These microorganisms showing endophytic lifestyles play crucial roles in plant development, growth, fitness, and diversification. The increasing awareness of and information on endophytes provide insight into the complexity of the plant microbiome. The nature of plant-endophyte interactions ranges from mutualism to pathogenicity. This depends on a set of abiotic and biotic factors, including the genotypes of plants and microbes, environmental conditions, and the dynamic network of interactions within the plant biome. In this review, we address the concept of endophytism, considering the latest insights into evolution, plant ecosystem functioning, and multipartite interactions.EU Cost Action [FA1103, 312117]; FWF (Austrian Science Foundation) [P26203-B22, P24569-B25]; Portuguese FCT (Foundation for Science and Technology) [SFRH/BPD/78931/2011]info:eu-repo/semantics/publishedVersio
