1. Overexpression of miR-484 and miR-744 in Vero cells alters Dengue virus replication
BACKGROUND Dengue is considered one of the world’s most important mosquito-borne diseases. MicroRNAs (miRNAs) are small non-coding single-stranded RNAs that play an important role in the regulation of gene expression in eukaryotes. Although miRNAs possess antiviral activity against many mammalian-infecting viruses, their involvement in Dengue virus (DENV

2. Effectiveness and cost-effectiveness of home palliative care services for adults with advanced illness and their caregivers
BACKGROUND: Extensive evidence shows that well over 50% of people prefer to be cared for and to die at home provided circumstances allow choice. Despite best efforts and policies, one-third or less of all deaths take place at home in many countries of the world. OBJECTIVES: 1. to quantify the effect of home palliative care services for adult patients with

4. Morbidade materna grave por aborto no Brasil / Severe maternal morbidity due to abortion in Brazil
Introduction: Still today abortion is associated with high rates of maternal morbidity and mortality. The maternal near miss, according to WHO (World Health Organization) it corresponds that woman who almost died but survived a complication during pregnancy, delivery or until 42 days postpartum, is currently understood as an important health indicator. Howev

5. Efficiency dynamics on two coupled small-world networks
We investigate the effect of clusters in complex networks on efficiency dynamics by studying a simple efficiency model in two coupled small-world networks. It is shown that the critical network randomness corresponding to transition from a stagnant phase to a growing one decreases to zero as the connection strength of clusters increases. It is also shown for

6. Influência do montelucaste sobre o estado de ativação dos eosinófilos e função dos fagócitos em crianças asmáticas
Asthma is one of the most common chronic diseases in childhood and its prevalence and severity are increasing in many parts of the world in recent years. The main characteristic of asthma is inflammation of the lower airways, responsible for bronchial hyperresponsiveness and variable airflow limitation, reversible with or without treatment. Several cells pla

7. Compactação do solo e desenvolvimento de couve-brócolo sob diferentes intensidades de tráfego de tratores
Intensive and mechanised agriculture took care of the necessities of the increasing world-wide demand for agricultural products, and at the same time, was the cause of negative effect in the fertility in the soil, the preservation of the natural resources and in the development and productivity of plants. This work compared the levels of compacting in the so

8. A RELAÇÃO DE LEAD-LAG ENTRE O ÍNDICE DOW JONES INDUSTRIAL AVERAGE FUTURO E À VISTA / THE LEAD-LAG RELATIONSHIP BETWEEN THE SPOT AND FUTURE DOW JONES INDUSTRIAL AVERAGE INDEX
With the internet birth, markets are more connected and accurately priced each day. The possibility to buy and sell assets online contributed to markets efficiency, hence now it¿s easier to spread and price new information. The efficient market theory says that assets prices must react instantly to new information, thus there should be no space for arbitrag

9. Uma alternativa a inundação baseada em tabelas de dispersão para planos de controle de redes opticas / A hash table based flooding alternative for optical networks control plane
The transport layer structure of the Internet is moving towards a model of highspeed routers interconnected by intelligent optical core networks. A consensus has been reached on wavelength division multiplexing (WDM) as the way to increase the transmission capacity. However there are few proposals for distributed control planes under dynamic Quality of Servi

10. Evaluation of the role of prohibitin in the development of resistance in cisplatin-treated human melanomas cells / Avaliação do papel de proibitina no desenvolvimento de resistência à cisplatina em linhagens de melanoma humano
The incidence of melanomas has grown world-wide. Besides representing a potential problem of public health for its increasing incidence, melanomas are tumors of difficult treatment, especially when diagnosed in advanced phases. The clinical objective response rate does not exceed 30% in these cases. The molecular bases of chemoresistance are not completely c

12. Complex network and self-organized criticality: models and applications / Rede complexa e criticalidade auto-organizada: modelos e aplicações
Models and scientific theories arise from the necessity of the human being to better understand how the world works. Driven by this purpose new models and techniques have been created. For instance, one of these theories recently developed is the Self-Organized Criticality, which is shortly introduced in the Chapter 2 of this thesis. In the framework of the
