Abstract: the nurse has a key role in involving parents in the care of newborns in the neonatal intensive care unit. the aim of this study was to comprehend how the nurses experience the care provided to newborns in the presence of the parents. this is a qualitative study using social phenomenology, with the participation of seven nurses, interviewed between january and february 2009. the nurses perceived the needs of parents; had positive expectations regarding the care provided and acknowledge themselves to be the link between them, helping them to live with the hospitalized child. however, in emergencies, the nurses had difficulties in caring for the neonate in the presence of the parents. the nurses positively evaluated the presence of parents in the neonatal intensive care unit, involving them permanently in the care of the newborn. the study evokes the emergence of a care context (nurse/neonate/parents) that precedes the proximity between the subjects and the demands presented by them.

Abstract: Considering Single Health System (SUS) principles, the social mobilization for achievements in health, has great significance. This mobilization is a guarantee that people will participate in the process of policies formulation designed to health needs and quality of life. Therefore, this research aimed to encourage community leaders of neighborhoods from Basic Health Unit (BHU) Model region - Campo Mour o, PR, to mobilize their communities to explore different ways to increase the transit security. Besides, this research also objective to evaluate results of social mobilization. Students of Nursing (Integrado College from Campo Mour o), the community and the health UBS Model group established the local epidemiological profile. Thus, an intervention project was carried out to stimulate the mobilization of leaders to make an undersigned in their respective districts, to ensure the presence of a transit guard at the access transit route (BR 158 road) in UBS Model region. The indicator to evaluating community mobilization was the proportion of residents in UBS Model area aged over 18 years (2,792 individuals) who attended the undersigned. Data show that 7.02% of undersigned was over than 18 years, from these, 62.01% were female and 37.99% were male. Considering the region of residence: 37.00% were from Jardim Modelo; 19.40% from Jardim Santa Cruz; 12.85% from Jardim Silvana; 12.20% from Jardim Batel; 11.55% from Jardim Mario Figueiredo and no signature was collected at Jardim Esperan a. Regarding the proportion of signatures, results are proportional to population number in each region. Thus, community mobilization to undersigned, held by leaders from neighborhood, was low, and that popular participation in health at UBS model region should be reconsidered. It is necessary the development of methodological strategies to increase the latent capacity of persons (stakeholders), stimulating their potential.

Abstract: tanniferous plants represent a promising alternative for controlling gastrointestinal nematodes of small ruminants. this experiment evaluated the effects of extracts from the leaf and stem of anadenanthera colubrina, leucaena leucocephala and mimosa tenuiflora on larval exsheathment of haemonchus contortus in vitro and verified the role of tannins in this process. third-stage larvae of h. contortus were incubated with extracts for 3 hours and were exposed to sodium hypochlorite solution. the extracts were tested at 300 μg.ml-1 and accompanied by controls: phosphate buffer solution (pbs) and polyvinyl polypyrrolidone (pvpp). the larval exsheathment was evaluated for 60 minutes, and the results were subjected to the kruskal-wallis test (p < 0.05). the six extracts blocked larval exsheathment. after pvpp addition, a tannin inhibitor, the exsheathment percentage was similar to the pbs (p > 0.05), except for l. leucocephala and m. tenuiflora leaf extracts. however, pre-incubation with pvpp of these two extracts significantly changed larval exsheathment when compared to the non-treated extracts (p < 0.05). these results suggest that a. colubrina, l. leucocephala and m. tenuiflora could be useful in gastrointestinal nematode control and that tannins are probably the main compounds involved in the observed effects. however, in vivo and toxicological studies should be conducted.

Abstract: New technological advances have been challenging professionals in education area to reach the new generation of students. Since this new generation is surrounded by this new technology, it is mandatory to associate new practices and teaching methods to their education plan. In this way, educators must reflect not only on their usual pedagogical practices but also in the efficacy of the method that has been practiced in the teaching and learning process. Technical Drawing is a discipline that takes place in High School programs in addition to Technical and Higher Education. It is directly influenced by this technological advance, once the student goes from the draw in the paper to the draw in computers during the classes and is encouraged to execute the projects that arise from the step-by-step draw. In this context, this work aimed to show a study performed during the Technical Drawing discipline to report a new structure in the educational methodology related to project-based learning. The focus of this study was to encourage students to develop a greater interest in engineering using project based learning and use this as a method for learning.
Plasmodium falciparum Infection Induces Expression of a Mosquito Salivary Protein (Agaphelin) That Targets Neutrophil Function and Inhibits Thrombosis without Impairing Hemostasis

Abstract: Background Invasion of mosquito salivary glands (SGs) by Plasmodium falciparum sporozoites is an essential step in the malaria life cycle. How infection modulates gene expression, and affects hematophagy remains unclear. Principal Findings Using Affimetrix chip microarray, we found that at least 43 genes are differentially expressed in the glands of Plasmodium falciparum-infected Anopheles gambiae mosquitoes. Among the upregulated genes, one codes for Agaphelin, a 58-amino acid protein containing a single Kazal domain with a Leu in the P1 position. Agaphelin displays high homology to orthologs present in Aedes sp and Culex sp salivary glands, indicating an evolutionarily expanded family. Kinetics and surface plasmon resonance experiments determined that chemically synthesized Agaphelin behaves as a slow and tight inhibitor of neutrophil elastase (KD~10 nM), but does not affect other enzymes, nor promotes vasodilation, or exhibit antimicrobial activity. TAXIscan chamber assay revealed that Agaphelin inhibits neutrophil chemotaxis toward fMLP, affecting several parameter associated with cell migration. In addition, Agaphelin reduces paw edema formation and accumulation of tissue myeloperoxidase triggered by injection of carrageenan in mice. Agaphelin also blocks elastase/cathepsin-mediated platelet aggregation, abrogates elastase-mediated cleavage of tissue factor pathway inhibitor, and attenuates neutrophil-induced coagulation. Notably, Agaphelin inhibits neutrophil extracellular traps (NETs) formation and prevents FeCl3-induced arterial thrombosis, without impairing hemostasis. Conclusions Blockade of neutrophil elastase emerges as a novel antihemostatic mechanism in hematophagy; it also supports the notion that neutrophils and the innate immune response are targets for antithrombotic therapy. In addition, Agaphelin is the first antihemostatic whose expression is induced by Plasmodium sp infection. These results suggest that an important interplay takes place in parasite-vector-host interactions.

Ribeiro, Moneda Oliveira;
Revista da Escola de Enfermagem da USP , 1999, DOI: 10.1590/S0080-62341999000400006
Abstract: the author develops a reflexion about foucault conception in relation to the "sexuality dispositive" that has been presented in the book "microfísica do poder". she tries to rescue, through this classic literature, a historic and social point of view in the practice of nursing, without missing the actual concepts that depreciate the affection of the personal relations at overvalorize the masculine virilate, converting the pleasure a consumer goods and a goal itself.
A política africana do brasil no pós-guerra fria

Abstract: this article analyzes brazil's foreign policy for africa during the post-cold war period. as a permanent theme within the brazilian diplomatic agenda for decades, brazil-africa relations have taken on a salient role within lula administration foreign policy. we attempt to understand the meanings and possibilities that it opens up for brazil throughout the african continent. we do this by giving emphasis to the political and commercial dynamics between this country and its african partners, and we employ the following analytical variables: the diplomatic actions and the commercial flows that brazil has established with african countries of the sub-sahara region. as our main argument, we maintain that the end of the cold war brought substantial change within the brazilian diplomatic agenda, directly affecting brazil's relationship with its african partners. thus, we argue that brazil-africa relations have been characterized by intensely variable movement, with accentuated decline between the decades of the 1980s and 1990s and recovery and possible intensification during the lula administration. our work can be divided into four parts. in the first, we present a general picture of brazil-africa relations during the period that precedes the 1980s. this is followed by a focus on the restrictive impact of international economic crises on african and brazilian realities, seeking to identify their repercussion on brazilian foreign policy with regard to africa. the third part looks at possible opening up toward brazil on the african continent, placing emphasis on the directives and proposals for foreign policy developed by the lula government. the last section attempts to provide a synthesis of the arguments that have been developed.
