Yet, we lack a unified understanding of how such trade-offs vary across the world's forests. By mapping life history traits for a wide range of species across the Americas, we reveal considerable variation in life expectancies from 10 centimeters in diameter (ranging from 1.3 to 3195 years) and show that the pace of life for trees can be accurately classified into four demographic functional types. We found emergent patterns in the strength of trade-offs between growth and longevity across a temperature gradient. Furthermore, we show that the diversity of life history traits varies predictably across forest biomes, giving rise to a positive relationship between trait diversity and productivity. Our pan-latitudinal assessment provides new insights into the demographic mechanisms that govern the carbon turnover rate across forest biomes.European Union Horizon 2020Royal SocietyNatural Environment Research Council (NERC

Work accidents and self-esteem of nursing professional in hospital settings

Resumo Objetivo: analizar la ocurrencia de accidentes de trabajo y la autoestima de profesionales de enfermería en ambientes hospitalarios en un municipio de Minas Gerais. Método: estudio descriptivo, analítico y transversal, desarrollado con 393 profesionales de enfermería de tres hospitales de un Municipio del sur de Minas Gerais. Para recolección de datos se utilizó la Escala de Autoestima de Rosenberg y un cuestionario de caracterización de la población y de accidente de trabajo. Para analizar los datos fueron utilizadas las pruebas de Person, Exacta de Fisher, Alfa de Cronbach, odds ratio y regresión logística. Resultados: de los profesionales investigados, 15% sufrieron accidente de trabajo y 70,2% poseía autoestima alta. Por medio del análisis, se observó que el tabaquismo, la creencia religiosa y el evento excepcional en la carrera presentaron asociación significativa con accidente de trabajo. En relación a la autoestima, la renta familiar mensual, el tiempo de actuación en la profesión y el evento excepcional en la carrera, tuvieron asociación significativa. Conclusión: factores como tabaquismo, creencia religiosa, renta familiar, tiempo de actuación en la profesión y evento excepcional en la carrera, pueden ocasionarle al profesional un accidente y/o provocar alteraciones en la autoestima, lo que puede comprometer su salud física y mental y su calidad de vida y trabajo.Objetivo: analisar a ocorrência de acidentes de trabalho e a autoestima de profissionais de enfermagem em ambientes hospitalares de um município de Minas Gerais.

Para análise dos dados foram utilizados os testes Qui-quadrado de Person, Exato de Fisher, Alfa de Cronbach, odds ratio e regressão logística. Resultados: dos profissionais pesquisados, 15% sofreram acidente de trabalho e 70,2% possuía autoestima alta. Por meio das análises, observou-se que o tabagismo, a crença religiosa e o evento marcante na carreira apresentaram associação significativa com acidente de trabalho. Em relação a autoestima, a renda familiar mensal, o tempo de atuação na profissão e o evento marcante na carreira tiveram associação significativa. Conclusão: fatores como tabagismo, crença religiosa, renda familiar, tempo de atuação na profissão e evento marcante na carreira podem conduzir o profissional ao acidente e/ou provocar alterações na autoestima, podendo comprometer a sua saúde física e mental e sua qualidade de vida e trabalho.Objective: to analyze the occurrence of work accidents and the self-esteem of nurses in hospitals of a municipality of Minas Gerais. Method: descriptive-analytical and cross-sectional study developed with 393 nursing professionals from three hospitals of a municipality in southern Minas Gerais. The Rosenberg Self-Esteem Scale and a questionnaire to characterize the population and work accidents were used for data collection. Data analysis was performed using Person's chi-squared test, Fisher's exact test, Cronbach's alpha, odds ratio and logistic regression. Results: of the professionals studied, 15% had suffered an accident at work and 70.2% presented high self-esteem. Through the analysis, it was observed that smoking, religious belief and an outstanding event in the career were significantly associated with work accidents. In relation to self-esteem, family income, length of time working in the profession and an outstanding event in the career presented significant associations. Conclusion: factors such as smoking, religious belief, family income, length of time working in the profession and an outstanding event in the career can cause professionals to have accidents and/or cause changes in self-esteem, which can compromise their physical and mental health and their quality of life and work

The relationship between SNPS in the genes of TLR signal transduction pathway downstream elements and rheumatoid arthritis susceptibility

Toll-like receptors (TLRs) play an important role in the induction and regulation of the innate immune system or adaptive immune responses. Genetic variations within human TLRs have been reported to be associated with rheumatoid arthritis (RA). This study was conducted to investigate correlation between SNP of downstream mononucleotide in signal transduction of Toll-like receptors and predisposing genes of RA. There was obviously correlative between single nucleotide polymorphism and predisposing genes of RA. G-type of IL-1RAP rs766442 may be protecting genes of RA, while T-type alleles of IL-6R rs11265618 and IL-1RAP rs766442 may be susceptible genes of RA. In conclusion, the studies on the nucleis acid polymorphism in TLRs signal pathway contribute to disclose genes’ influence on the attack mechanism of RA, early diagnosis and treatment of RA.Толл-подобные рецепторы (TLRs) играют важную роль в индукции и регуляции врожденной иммунной системы или адаптивных иммунных ответах. Показано, что что генетическая изменчивость TLRs человека связана с ревматоидным артритом (РА). Целью настоящей работы было изучение корреляций между однонуклеотидным полиморфизмом в сигнальной трансдукции TLRs и генами предрасположенности к РА. G-тип IL-1RAP rs766442 могут быть генами, предохраняющими от РА, в то время как аллели T-типа IL-6R rs11265618 и IL-1RAP rs766442 могут быть генами чувствительности к РА. Изучение полиморфизма нуклеиновых кислот в сигнальном пути TLRs может внести вклад в выявление участия генов в механизмах приступов РА, раннюю диагностику и лечение РА.The study was supported by Shandong Province young scientist in incentive fund (Grant № 2006BS03018) and National Natural Science Foundation of China (Grant № 30801025)
