Análise quantitativa da deglutição orofaríngea em indivíduo gastrostomizado com Lipofuscinose Ceróide Neuronal: relato de caso

The presence of oropharyngeal dysphagia in the pediatric population with genetic diseases it is still poorly studied. The aim of this study was to analyze the oral total transit time and pharyngeal transit time, in an individual with neuronal ceroid lipofucinosis (NCL) with severe oropharyngeal dysphagia. Individual with NCL, 3 years old, 2 years with gastrostomy and no oral feeding, weighting loss, but without pulmonary complications. Oropharyngeal swallowing was studied by videofluoroscopy and it was realized a quantitative analysis using software. Changes were observed throughout the whole biomechanics of swallowing. The quantitative analysis of total oral transit time was found 45.37 seconds (default normality in children is 4 seconds) and for pharyngeal transit time was 4.53 seconds. It was found that beside the changes in the biomechanics of oropharyngeal swallowing in the case studied, an increase in total oral transit time and pharyngeal transit time was also observed, which can significantly compromise the nutritional status and pulmonary these individuals.

Leaf Morphological Plasticity of Tree Species from Two Developmental Stages in Araucaria Forest

This study compared the morphological and anatomical variations of the leaves of four shade-tolerant tree species Allophylus edulis (St.-Hil.) Radlk (Sapindaceae), Casearia sylvestris Sw. (Salicaceae), Cupania vernalis Cambess. (Sapindaceae) and Luehea divaricata Mart. (Malvaceae) from a fragment of Araucaria forest in two developmental stages. Morphological and anatomical traits, such as leaf and tissue thickness, leaf area, leaf dry mass, specific leaf area, leaf density and stomata density were measured from 30 leaves of each developmental stage. The phenotypic plasticity index was also calculated for each quantitative trait. The results showed that the four species presented higher mean values ​​for specific leaf area and spongy/palisade parenchyma ratio at young stage, and higher mean values ​​for stomata density, total and palisade parenchyma thickness in the adult stage. The plasticity index demonstrated that L. divricata presented highest plasticity for both the morphological and anatomical traits while A. edulis displayed the lowest plasticity index. The results of this study indicated that the leaves of these species exhibited distinct morphological traits at each stage of development to cope with acting environmental factors.

Post-partum anoestrus in tropical beef cattle: A systems approach combining gene expression and genome-wide association results

The length of the post-partum anoestrous interval affects reproductive efficiency in many tropical beef cattle herds. In this study, results from genome-wide association studies (Experiment 1: GWAS) and gene expression (Experiment 2: microarray) were combined in a systems approach to reveal genetic markers, genes and pathways underlying the physiology of post-partum anoestrus in tropically adapted cattle. The microarray study measured the expression of 13,964 genes in the hypothalamus of Brahman cows. A total of 366 genes were differentially expressed (DE) in the post-partum period, when acyclic cows were compared to cows that had resumed ovarian cycles. Associated markers (P < 0.05) from a high density GWAS pointed to 2829 genes that were associated with post-partum anoestrous interval (PPAI) in two populations of beef cattle: Brahman and Tropical composite. Together the experiments provided evidence for 63 genes that are likely to influence the resumption of ovulation post-partum in tropically adapted beef cattle. Functional annotation analysis revealed that some of the 63 genes have known roles in hormonal activity, energy balance and neuronal synapse plasticity. Polymorphisms within candidate genes identified by this systems approach could have biological significance in post-partum anoestrus and help select Zebu (Bos indicus) influenced cattle with genetic potential for shorter post-partum anoestrus.
