Producing Brazilian Cerrado plants, especially ones endangered, is essential for your maintenance. In this way, fertilization is furthermore uncertain. Here, we demonstrate the impact of soil addition of nitrogen (N, 4.20, 18.90, 31.50, 44.10 and 59.85 mg·dm-3) and phosphorus (P, 9.56, 57.38, 95.62, 133.86 and 181.67 mg·dm-3) fertilizers levels on the development and on nutrients uptake by Jacaranda decurrens subsp. symmetrifoliolata (carobinha), species of the Brazilian Cerrado, in a long term pot trial. The N and P addition together increased plant height and N concentration in roots. N and P also increased the P concentration and content on the roots in young plants, but in the older plants, isolated effect of both was stronger than their combined action. The N addition promoted branching, production of dry leaves and dry xylopodium, contents of K, Ca and P on the leaves, and N content on the roots. However, the N reduced xylopodium diameter, leaf area, and Mg contents in the young plants, but increased them in the older plants. The P addition increased stem diameter and dry biomass, P concentration and N content on the leaves, Ca content on the roots and also reduced N concentration on the leaves. However, the P addition increased Mg concentration on the roots in the young plants and reduced it in the older plants. In general, N levels ranging between 25.69 - 38.85 mg·dm-3 and P levels between 84.39 - 109.23 mg·dm-3 promote more effectively the plant development. Thus, N and P fertilization can promote the aerial development of plant and a differential allocation of nutrients between the carobinha tissues.

Railway for Tourism in South America： An Approach on Its Uses

Journal of Traffic and Transportation Engineering 2016年第6期4卷 339-349页

作者： thiago Allis Carla Fraga Maximiliano Augusto Velazquez Department of Geography Tourism and Humanities Federal University of Sao Carlos Sorocaba Sao Paulo 18052-780 Brazil Department of Tourism and Heritage Federal University of the State of Rio de Janeiro Rio de Janeiro 22290-240 Brazil Center for Metropolitan Transportation Studies (CETAM) Universidad de Buenos Aires City of Buenos Aires C1428EGAArgentina

In this paper, the authors focus on the interplay between railways and tourism. Therefore, evidence is provided in order to decipher the manner in which railways are used for tourism purposes in South America. With a view to achieving this goal, an exploratory approach is used, which consists in the analysis of publications on tourism and transportation made by renowned scholars, as well as a descriptive approach, based upon the classification of data obtained from public and private railway organizations. The paper notes that tourism is of paramount importance in the protection of the railway heritage in South America. Following this line of reasoning, it is concluded that there is a wide variety of tourist trains which exploit either the cultural and historical aspects of railways or the bewitching landscapes offered by railway trips and create experiences for tourists.

Subversion of cellular stress responses by poxviruses

引用

World Journal of Clinical Infectious Diseases 2014年第4期4卷 27-40页

作者： thiago Lima Leao Flávio Guimaraes da Fonseca Laboratório de Virologia Básica e Aplicada Departamento de Microbiologia Instituto de Ciências Biológicas Universidade Federal de Minas Gerais Belo Horizonte MG 31270-901 Brasil

Cellular stress responses are powerful mechanisms that prevent and cope with the accumulation of macromolecular damage in the cells and also boost host defenses against pathogens. Cells can initiate either protective or destructive stress responses depending, to a large extent, on the nature and duration of the stressing stimulus as well as the cell type. The productive replication of a virus within a given cell places inordinate stress on the metabolism machinery of the host and, to assure the continuity of its replication, many viruses have developed ways to modulate the cell stress responses. Poxviruses are among the viruses that have evolved a large number of strategies to manipulate host stress responses in order to control cell fate and enhance their replicative success. Remarkably, nearly every step of the stress responses that is mounted during infection can be targeted by virally encoded functions. The fine-tuned interactions between poxviruses and the host stress responses has aided virologists to understand specific aspects of viral replication; has helped cell biologists to evaluate the role of stress signaling in the uninfected cell; and has tipped immunologists on how these signals contribute to alert the cells against pathogen invasionand boost subsequent immune responses. This review discusses the diverse strategies that poxviruses use to subvert host cell stress responses.

Journal of Biomaterials and Nanobiotechnology 2013年第1期4卷 98-106页

作者： Alicia Valeria Zaranza Francyelle Costa Morais Monique Santos do Carmo Adriana de Mendonca Marques Cristina Andrade-Monteiro thiago Feitosa Ferro Valerio Monteiro-Neto Patricia de Maria Silva Figueiredo Research Center in Parasitic Diseases and Endemic University of CEUMAUniCEUMASao LuisBrazil

A hundred Pseudomonas aeruginosa strains from several clinical specimens from five hospitals in Sao Luís-MA were evaluated for biofilm production, prevalence of the gene algD, adhesion to HEp-2 cells and antimicrobial susceptibility. The most affected clinical specimens and hospital sectors were also evaluated. Most isolates were obtained from the tracheal aspirate (21.0%) and the most affected hospital sector was the ICU (43.0%). The antibiotics with the highest sensitivity rate were amikacin, piperacillin/tazobactam, fluoroquinolones, gentamicin and meropenem and the ones with the highest resistance rate were aztreonam, ceftazidime and cefepime. All samples were sensitive to polymyxin B. In relation to the expression of the gene for ESBL, 50.0% (17/34) of the multiresistant strains showed the enzyme TEM. Most strains showed high hydrophobicity and 96% of the isolates produced biofilm on a polystyrene microplate, 52% were capsule producers, 19% showed mannose-sensitive fimbriae and 39% expressed the gene algD. We observed adhesion to HEp-2 cells and to the coverslip. These factors may be reported in the pathogenesis of this bacterium, what represents a potential risk for colonization of medical devices which favor the establishment of chronic nosocomial infections.

全球经济发展带来城市社群的巨大变革,城市场景也在数十年间发生了动态化的演进。从社会学经典发展理论来看,场景经历了发展、分化、扩散和防御的变化过程。以美国主要城市场景的变化为分析案例,发展模式表现了场景的现代化转变;在发展过程中,场景随之发生专业化细分,形成了场景的分化模式,其主要强调舒适物的结构性变化;扩散模式则解释了场景变化的原因,并形成了C型和S型两种扩散曲线;而扩散也将带来目的地原有场景的抵御,进一步阐释场景变化与否的原因。4D模式可用于分析场景变化的多重交叠机制,为场景发展和演化的综合研究提供新的借鉴。
