13. Defensive responses to threat scenarios in Brazilians reproduce the pattern of Hawaiian Americans and non-human mammals
A former study with scenarios conducted in Hawaii has suggested that humans share with non-human mammals the same basic defensive strategies - risk assessment, freezing, defensive threat, defensive attack, and flight. The selection of the most adaptive strategy is strongly influenced by features of the threat stimulus - magnitude, escapability, distance, amb

14. A busca do corpo ideal como sintoma contemporâneo: os significados do corpo para os adolescentes masculinos que freqüentam academias de ginástica na cidade de Montes Claros MG
The objective of this research goes into understanding the senses attributed to the body by the male adolescents, frequenting fitness centers in the city of Montes Claros MG, acting as motivating factors for the practice of physical training and for the consumption of energetic or anabolic steroids. Nine male adolescents were interviewed chosen from two fitn

15. Mapping the molecular characteristics of Brazilian human T-cell lymphotropic virus type 1 Env (gp46) and Pol amino acid sequences for vaccine design
This study was carried out to evaluate the molecular pattern of all available Brazilian human T-cell lymphotropic virus type 1 Env (n = 15) and Pol (n = 43) nucleotide sequences via epitope prediction, physico-chemical analysis, and protein potential sites identification, giving support to the Brazilian AIDS vaccine program. In 12 previously described peptid

16. Motivações para adoção: uma perspectiva da Psicologia Evolucionista
Parental investment increases the offsprings survival, though it decreases the opportunities for the parents to invest in a future progeny. In a broad sense, this investment is directed to ones own descendant, but in some cases, such as in adoption, resources are directed to non-relatives even in the absence of fitness benefits. Once there are many factors i

17. Obtenção de tabela de quantização para compressão de imagens utilizando algoritmos genéticos
The purpose of this work is to generate a better Quantization Table for a group of natural images and medical images using the Genetic Algorithm method in the process of compression JPEG. The fitness function of the population will be analyzed and the probability of selection the better pairs of chromosomes or matrix, and we will also breach means to improve

18. Da escala médica de saúde à experiência social do saudável :diálogo entre os espaços dos bares e das academias fisiculturistas na cidade do Natal-RN
Currently, we attend a reverence of concepts ahead as health, life, youth and body. In we widen amount the ideals concerned to the healthful life, to the quality of life, the longevity and joviality and the extremities of the body represented by the illness, for the virus infection, the physical deficiency and the aging. Of the historical shades of the plagu

19. Princípio constitucional da proporcionalidade no processo penal
The principle of the proportionality constitution is treat here as a mechanism for the accomplishment of human dignity during the penal process. The dissociation between the constitutional guarantees of a penal law suit situation and reality motivated this dissertation research. The must be, in this stage during the process which man stands as the main actor

20. Programação de alimentação escolar : avaliação do desempenho em dez municipios brasileiros
The National School Meal Program in Brazil aims to improve the student nutritional conditions and his learning capability such as to develop good feed habits, through meal distribution during classroom breaks. fts management has been decentralized since 1993 when the counties started to receive funds from the Federal Government for food acquisition and impor

21. Efeito da infeccao com Wuchereira bancrofti (Cobbald, 1877) (Nematoda : Onchocercidae) sobre a capacidade reprodutiva de Culex quiquefasciatus (Say, 1823) (Diptera : Culicidae)
Lymphatic filariasis is one of the most important human diseases transmitted by mosquitoes. Understanding of vector/parasite interactions is essential for rational development of filariasis control. This study was undertaken in order to determine whether the filarial parasite would interfere with the reproductive fitness of the mosquito Culex quinquefasciatu

22. Role of the Human Immunodeficiency Virus Type 1 Envelope Gene in Viral Fitness
A human host offers a variety of microenvironments to the infecting human immunodeficiency virus type 1 (HIV-1), resulting in various selective pressures, most of them directed against the envelope (env) gene. Therefore, it seems evident that the replicative capacity of the virus is largely related to viral entry. In this study we have used growth competitio

23. Comparing the Ex Vivo Fitness of CCR5-Tropic Human Immunodeficiency Virus Type 1 Isolates of Subtypes B and C
Continual human immunodeficiency virus type 1 (HIV-1) evolution and expansion within the human population have led to unequal distribution of HIV-1 group M subtypes. In particular, recent outgrowth of subtype C in southern Africa, India, and China has fueled speculation that subtype C isolates may be more fit in vivo. In this study, nine subtype B and six su

24. Resistance-Associated Loss of Viral Fitness in Human Immunodeficiency Virus Type 1: Phenotypic Analysis of Protease and gag Coevolution in Protease Inhibitor-Treated Patients
We have studied the phenotypic impact of adaptative Gag cleavage site mutations in patient-derived human immunodeficiency virus type 1 (HIV-1) variants having developed resistance to the protease inhibitor ritonavir or saquinavir. We found that Gag mutations occurred in a minority of resistant viruses, regardless of the duration of the treatment and of the p
