Deep sequencing of the Mexican avocado transcriptome, an ancient angiosperm with a high content of fatty acids

Background: Avocado (Persea americana) is an economically important tropical fruit considered to be a good source of fatty acids. Despite its importance, the molecular and cellular characterization of biochemical and developmental processes in avocado is limited due to the lack of transcriptome and genomic information. Results: The transcriptomes of seeds, roots, stems, leaves, aerial buds and flowers were determined using different sequencing platforms. Additionally, the transcriptomes of three different stages of fruit ripening (pre-climacteric, climacteric and post-climacteric) were also analyzed. The analysis of the RNAseqatlas presented here reveals strong differences in gene expression patterns between different organs, especially between root and flower, but also reveals similarities among the gene expression patterns in other organs, such as stem, leaves and aerial buds (vegetative organs) or seed and fruit (storage organs). Important regulators, functional categories, and differentially expressed genes involved in avocado fruit ripening were identified. Additionally, to demonstrate the utility of the avocado gene expression atlas, we investigated the expression patterns of genes implicated in fatty acid metabolism and fruit ripening. Conclusions: A description of transcriptomic changes occurring during fruit ripening was obtained in Mexican avocado, contributing to a dynamic view of the expression patterns of genes involved in fatty acid biosynthesis and the fruit ripening process

Depressão, cortisol urinário e perfil sócio-demográfico de portadores de diabetes mellitus tipo 2 Depresion, el cortisol urinario y perfil sociodemografico em portadores de diabetes mellitus tipo 2 Depression, urinary cortisol and social demographics characteristics in subjects with type 2 diabetes mellitus

O objetivo deste estudo foi investigar a relação entre indicadores de depressão e perfil sócio-demográfico de portadores de Diabetes Mellitus tipo 2 (DM2).A avaliação sócio-demográfica foi conduzida em amostra composta por 40 pacientes na Liga de Diabetes (HC-FMUSP).Os indicadores de depressão foram investigados a partir do Inventário de Depressão de Beck (IBD) em associação com cortisol urinário (CORT).Os resultados mostraram que indivíduos portadores de DM2 com alta escolaridade, baixo poder aquisitivo individual e familiar e com história de rompimento de relação conjugal estável estão mais propensos a sintomas de depressão.<br>Lo objective deste estudo fue investigar la relación entre la depresión y los indicadores de perfil socio-demográfico de los pacientes con diabetes mellitus tipo 2 (DM2). Evaluación socio-demográficos se llevó a cabo en una muestra de 40 pacientes en la Liga de la Diabetes (HC-FMUSP). Indicadores de la depresión se han investigado en el Beck Depression Inventory (BDI),en asociación con el cortisol urinario (CORT).Resultados muestraron que los pacientes con DM2 con alto nivel de educación,las personas de bajos ingresos y familias con historia de interrupción de los matrimonios estables son más propensos a tener síntomas de la depresión.<br>The objective this study was investigate the relationship between depression indicators and social-demographics characteristics in subjects with Type 2 Diabetes Mellitus (DM2). The socio-demographic evaluation was conducted in a sample composed of 40 patients with DM2 from Diabetes League (HCFM-USP).Depression indicators were evaluated through the Beck Depression Inventory (BDI) in addition to urinary cortisol (CORT).The results showed that individuals with high education level,poor individual and familiar economic status in addition to history of broken stable relationship are more likely to depressive symptoms
