Processo ensino aprendizagem em saúde mental: o olhar do aluno sobre reabilita??o psicossocial e cidadania
Barros, Snia;Claro, Heloísa Garcia;
Revista da Escola de Enfermagem da USP , 2011, DOI: 10.1590/S0080-62342011000300022
Abstract: the current national mental health policies confirm the need to encourage teaching, research and extension practices that favor new professional attitude. a previous study has shown that the students' representation about the competencies required in mental health fall into categories about the concepts of competence, cognitive resources, expressed feelings, and the concept of health and illness, but with no reference to themes related to the users' citizenship or psychosocial rehabilitation, which are central concepts in the course discipline. in this study, an analysis was made of the representation about these concepts, the knowledge and skills identified as being necessary to practice rehabilitation. participants were students of a public university, attending the mental health nursing class. the results show that students value the users' needs, but the representations about citizenship and psychosocial rehabilitation are founded on common sense about hazards and basic rights like health and leisure.
Repeated reunions and splits feature the highly dynamic evolution of 5S and 35S ribosomal RNA genes (rDNA) in the Asteraceae family

BMC Plant Biology , 2010, DOI: 10.1186/1471-2229-10-176
Abstract: Dominant linked rDNA genotype was found within three large groups in subfamily Asteroideae: tribe Anthemideae (93% of the studied cases), tribe Gnaphalieae (100%) and in the "Heliantheae alliance" (23%). The remaining five tribes of the Asteroideae displayed canonical non linked arrangement of rDNA, as did the other groups in the Asteraceae. Nevertheless, low copy linked genes were identified among several species that amplified unlinked units. The conserved position of functional 5S insertions downstream from the 26S gene suggests a unique, perhaps retrotransposon-mediated integration event at the base of subfamily Asteroideae. Further evolution likely involved divergence of 26S-5S intergenic spacers, amplification and homogenisation of units across the chromosomes and concomitant elimination of unlinked arrays. However, the opposite trend, from linked towards unlinked arrangement was also surmised in few species indicating possible reversibility of these processes.Our results indicate that nearly 25% of Asteraceae species may have evolved unusual linked arrangement of rRNA genes. Thus, in plants, fundamental changes in intrinsic structure of rDNA units, their copy number and chromosomal organisation may occur within relatively short evolutionary time. We hypothesize that the 5S gene integration within the 35S unit might have repeatedly occurred during plant evolution, and probably once in Asteraceae.It is generally considered that in prokaryotes and in some species of early diverging eukaryote groups e.g. yeast, Saccharomyces cerevisiae, rRNA genes are organised in a single operon, clustered in tandem and transcribed by the same RNA polymerase. In eukaryotes, the 35S (encoding 18S-5.8S-26S rRNA) and 5S genes are transcribed by different polymerases, RNA polymerase I and III, respectively. Independent control of transcription probably enabled physical separation of both loci in chromosomes, an arrangement that is typical for most eukaryotic organisms. Nevertheless,
Expression of 5 S rRNA genes linked to 35 S rDNA in plants, their epigenetic modification and regulatory element divergence

Abstract: We found that homogenization of L-type units went to completion in most (4/6) but not all species. Two species contained major L-type and minor S-type units (termed Ls-type). The linked genes dominate 5?S rDNA expression while the separate tandems do not seem to be expressed. Members of tribe Anthemideae evolved functional variants of the polymerase III promoter in which a residing C-box element differs from the canonical angiosperm motif by as much as 30%. On this basis, a more relaxed consensus sequence of a plant C-box: (5’-RGSWTGGGTG-3’) is proposed. The 5?S paralogs display heavy DNA methylation similarly as to their unlinked counterparts. FISH revealed the close association of 35?S-5?S arrays with nucleolar periphery indicating that transcription of 5?S genes may occur in this territory.We show that the unusual linked arrangement of 5?S genes, occurring in several plant species, is fully compatible with their expression and functionality. This extraordinary 5?S gene dynamics is manifested at different levels, such as variation in intrachromosomal positions, unit structure, epigenetic modification and considerable divergence of regulatory motifs.Nuclear ribosomal DNA (rDNA) encoding 5?S, 5.8?S, 18?S and 26?S rRNA belong to the most important housekeeping genes playing a central role in cell metabolism [1]. In plant genomes there may be from several hundred up to tens of thousands of highly homogeneous copies of each gene. A high copy number of these genes is probably important to ensure increased demand for proteosynthesis during plant development [2] but other functions, such as stabilization of the cell nucleus, have also been proposed [3]. Each large 35?S (45?S in animals) rDNA unit contains 18?S, 5.8?S and 26?S rRNA genes, the internal transcribed spacers (ITSs), and an intergenic spacer (IGS) (for review see [4]). The 35?S units are organized in tandem arrays at one or several loci. The 5?S rDNA encoding a 120-bp-long transcript has been traditionally cons
A experiência da perimenopausa e pós-menopausa com mulheres que fazem uso ou n?o da terapia de reposi??o hormonal
Vigeta, Snia Maria Garcia;Brêtas, Ana Cristina Passarella;
Cadernos de Saúde Pública , 2004, DOI: 10.1590/S0102-311X2004000600027
Abstract: this qualitative study focuses on peri-menopausal and post-menopausal experience and its signs and symptoms for women with and without use of hormone replacement therapy (hrt). empirical data were obtained through interviews with 11 women (range: 45 to 59 years) with or without hrt at different health clinics in the municipality of s?o paulo, brazil. the analysis used the hermeneutic method. most significantly, women who are not on hrt present peri-menopausal symptoms, but they "live with" such symptoms; meanwhile, women in use of isoflavone rely on alternative therapies for the bothersome symptoms; women using hrt report a feeling of wellbeing. the article suggests the importance of training health professionals to understand the peri-menopausal and post-menopausal periods as part of the aging process, and thus as a vital rather than pathological process.

Abstract:


Goal: To evaluate the impact of iodine-131 therapy received during childhood and adolescence and correlate it with the quality of life in these patients. Methods: We studied 19 patients diagnosed with cancer in childhood or adolescence who underwent thyroidectomy and supplemental therapy with I-131. We also recruited a control group of healthy subjects with the same demographic parameters. All patients were subjected to a scintigraphy examination of the salivary glands, and were also asked to complete a questionnaire in order to assess their overall quality of life. In addition, a more specific questionnaire for patients with head and neck cancer was also given to all study participants. Results: The quantitative and qualitative analyses of the salivary glands showed functional deficits with greater involvement of the parotid gland for volume, concentration and excretion. The right submandibular gland showed significant changes for volume in the patient group. The questionnaires made it possible to observe significant differences between the patient and control groups for symptoms such as thick saliva, dry mouth and speech problems. Conclusion: In spite of being very effective and widely used, iodine radionuclide therapy is correlated with a lower quality of life in young people.

Journal of Botany , 2010, DOI: 10.1155/2010/797246
Abstract: The purpose of this study is to provide a new focus to contribute, from the perspective of genomic evolution, towards a better understanding of the Valerianaceae evolutionary history. Chromosome numbers were determined by Feulgen staining in 24 populations of 18 species (first count for Valerianella multidentata, –16), and DNA contents were assessed by flow cytometry in 74 populations of 35 species (first assessments in all taxa but Centranthus ruber). A molecular phylogeny based on the trnL-trnF and including 41 new sequences was established, with the first DNA sequence for Centranthus nevadensis, Valeriana rotundifolia, V. saxatilis, Valerianella multidentata, and V. turgida. This work is the first large genome size study devoted to the Valerianaceae, showing a range of DNA amounts from ?pg (Valerianella turgida) to ?pg (Valeriana officinalis). At the family level, changes in basic chromosome number and genome size coincide with or precede major shifts in the evolutionary history of the group, such as those concerning stamen number and floral symmetry. 1. Introduction The family Valerianaceae (currently considered within the Caprifoliaceae s.l.; [1]) comprises ca. 400 species of which approximately 200 are included in Valeriana L., the biggest genus of the order Dipsacales. The Valerianaceae are cosmopolitan in their natural distribution, with the exceptions of Australia and the Pacific islands, where they were introduced, and can be nowadays considered as naturalized. Several of their representatives have economic interest as medicinal (e.g., V. officinalis L.), edible (e.g., Valerianella Mill., corn salad or lamb’s lettuce), or ornamental plants (e.g., Centranthus DC.). The family always roused important scientific interest, and its study has broadly benefited from the new molecular techniques, especially the phylogenetic reconstructions. Recent phylogenies based on DNA sequencing [2–7] have considerably modified the traditional classification of the family [8–12]. Molecular results recognize only six genera: Centranthus, Fedia Gaertn., Nardostachys DC., Patrinia Juss., Valeriana (including Aretiastrum DC., Astrephia Dufr., Belonanthus Graebn., Phyllactis Pers., Porteria Hook., and Stangea Graebn.), and Valerianella. Plectritis (Lindl.) DC. is nested amongst South American Valeriana [5, 6]. Moreover, Bell [7] suggested a possible further taxonomic treatment of the family considering Fedia as a synonym of Valerianella. New genera may also be described for some of the Valeriana species that do not group with their congenerics in the phylogenetic

Abstract: the objective of this work was to evaluate the allelopathic potential of aqueous extracts of young and mature leaves from sapindus saponaria on diaspore germination and seedling growth of barnyardgrass (echinochloa crus-galli) and morningglory (ipomoea grandifolia). the aqueous extract was prepared in a proportion of 100 g of dried, ground leaves dissolved in 1000 ml of distilled water, resulting in a 10% extract concentrate. dilutions of this concentrate were made with distilled water to 7.5, 5.0 and 2.5%. in seedling growth tests, we compared the effect of these extracts with the herbicide nicosulfuron. both extracts of mature and young leaves caused delays and reductions in diaspore germination and seedling length of barnyardgrass and morningglory, with the most intense effects observed at a concentration of 10%. the effects of the young leaf extract were more similar to those observed with the herbicide, demonstrating that leaf maturation stage of s. saponaria affects its inhibitory effects on the growth of other plants and that this species is effective in controlling weeds.
