TRY plant trait database - enhanced coverage and open access

Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait-based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits-almost complete coverage for 'plant growth form'. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait-environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives

Social representations of needlestick injuries

OBJECTIVES: understand the Social Representations about needlestick injuries elaborated by Nursing Technicians and analyze how these representations influence their conducts. METHOD: the data, obtained by interviews, were processed using ALCESTE software and their analysis was based on Serge Moscovici's Social Representations Theory. RESULTS: it was evidenced that, after the accident, these professionals take care of the affected area. Then, they report the accident, motivated by the fear of catching HIV and hepatitis. The different feelings experienced are due to this fear and the way they were forwarded by the institution, reflecting in the cause they attribute to their accident. CONCLUSIONS: it was verified that knowledge about the accident as a whole is very incipient in this professional group, demanding continuing education and greater emphasis on this subject in professional training. It is expected that this study draws public authorities and health institutions' attention to the problem and that it modifies Nursing Technicians' Social Representations about percutaneous exposure.OBJETIVOS: Comprender las Representaciones Sociales de los accidentes con materiales corto-punzantes, elaboradas por Técnicos de Enfermería, así como analizar de que modo esas representaciones influencian las conductas de eses profesionales. MÉTODO: Los datos, logrados por medio de entrevistas, fueron procesados por el software ALCESTE y el análisis de los mismos fue basado en la Teoría de las Representaciones Sociales de Serge Moscovici. RESULTADOS: se evidenció que, después de accidentarse, los Técnicos de Enfermería cuidan del área afectada. Enseguida, notifican el accidente, motivados por el miedo de que contraigan HIV y hepatitis. Los diversos sentimientos vividos son consecuentes de ese miedo y de la manera como fueron encaminados por la institución, reflejando en la causa que ellos atribuyen a su accidente. CONCLUSIONES: se constató que hay un conocimiento bastante incipiente por parte de esa clase profesional sobre el accidente como un todo, habiendo necesidad de una educación continuada y mayor énfasis en cuanto a ese asunto durante la formación profesional. Se espera que ese estudio llame la atención de los órganos gubernamentales e instituciones de salud sobre el problema y modifique las Representaciones Sociales de la exposición percutánea de los Técnicos de Enfermería.OBJETIVOS: compreender as representações sociais dos acidentes com materiais perfurocortantes, elaboradas por técnicos de enfermagem, bem como analisar de que modo essas representações influenciam as condutas desses profissionais.

RESULTADOS: evidenciou-se que, após se acidentarem, os técnicos de enfermagem cuidam da área afetada. Em seguida, notificam o acidente, motivados pelo medo de contraírem HIV e hepatite. Os diversos sentimentos vivenciados são decorrentes desse medo e da forma como foram encaminhados pela instituição, refletindo na causa que eles atribuem ao seu acidente. CONCLUSÕES: constatou-se que há conhecimento bastante incipiente por parte dessa classe profissional sobre o acidente, como um todo, havendo necessidade de educação continuada e maior ênfase quanto a esse assunto, durante a formação profissional. Espera-se que este estudo chame a atenção dos órgãos governamentais e instituições de saúde sobre o problema e modifique as representações sociais da exposição percutânea dos técnicos de enfermagem

Escutando as mães de portadores de fissuras orais

Estudo descritivo com abordagem qualitativa. Objetivou a escuta e o relato sobre a etiologia da malformação e conhecer as crenças atribuídas pelos familiares à manifestação das fissuras orais. Os dados foram coletados de março a junho de 2009 por entrevista semi-estruturada e analisados por análise de conteúdo. Resultou em cinco categorias: reação da mãe, sentimentos das mães e da família, comportamento da equipe, conhecimento da causa e crenças. Os resultados permitiram conhecer as crenças sobre o tema e adequar as orientações da enfermagem e dos demais profissionais às mães de portadores de fissuras orais, auxiliando os familiares em todas as fases de desenvolvimento da criança durante o processo terapêutico

BIOCHEMICAL ANALYSIS AND BONE REMODELING IN RESPONSE TO OOPHORECTOMY AND AQUATIC TRAINING

ABSTRACT Objective: To investigate whether swimming could prevent bone loss and could be indicated to assist in treatment of osteoporosis. Methods: Female rats were divided into 4 groups (n=6), two of them were oophorectomized. Animals from two groups, one oophorectomized and another not oophorectomized, underwent aquatic training for eight weeks. After training, the animals were sacrificed and their blood was collected for calcium and alkaline phosphatase serum dosage; the femur was removed and subjected to radiological and histological densitometry analysis to assess bone loss and osteoclast counting on femoral head and neck. Results: Increase in serum calcium was not observed. There was an increasing activity of alkaline phosphatase in the oophorectomized groups. The radiographs suggest that there was a greater bone mass density in the trained groups. Concerning histology, the trained groups had better tissue structural organization than the sedentary groups. In the oophorectomized and sedentary group, higher presence of osteoclasts was observed a. Conclusion: Exercise and oophorectomy did not promote changes in serum calcium levels. The decrease of sex steroids caused by oophorectomy was responsible for severe bone loss, but swimming exercise was able to reduce this loss. Oophorectomy promoted the proliferation of osteoclasts and the exercise proved to be able to diminish it. Level of Evidence I, Experimental Study
