2. Are there differences in the growth adaptation processes of growing and mature organism models of short bowel syndrome?
OBJECTIVES: The purpose of this study was to present an experimental model of short bowel syndrome (SBS) in weaning rats and to compare the adaptative mechanisms of the remaining bowel in weaning rats and adult animals by means of morphometric, histologic and molecular methods. METHODS: Twenty-four weaning rats were divided into 3 groups of 8 animals, one

3. Modulação do transporte de prótons em osteoclastos: efeitos da acidose e do fluxo de fluido extracelular. / Modulation of proton transport in osteoclasts. Effects of acidosis and extracellular fluid flow.
Metabolic acidosis can cause a loss of bone mineral and the mechanic stimulation can cause adaptative bone remodeling. The bone resorption characteristic of these bone changes aforementioned depends on the extracellular acidification by osteoclastmediated proton secretion. The H+ secretion by vacuolar H+-ATPase together with Clsecretion through a Cl-/H+ exch

4. Differential expression of pathogenicity- and virulence-related genes of Xanthomonas axonopodis pv. citri under copper stress
In this study, we used real-time quantitative PCR (RT-qPCR) to evaluate the expression of 32 genes of Xanthomonas axonopodis pv. citri related to pathogenicity and virulence that are also involved in copper detoxification. Nearly all of the genes were up-regulated, including copA and copB. Two genes homologous to members of the type II secretion system (xcsH

5. Effect of soluble factors produced by TLR-activated macrophages on T lymphocytes survival. / Influência da ativação de macrófagos via receptores do tipo Toll (TLRs) na produção de fatores moduladores da sobrevivência de linfócitos T.
The interaction between innate and adaptative immunity occurs in several phases of the immune response. The Toll-like receptors (TLRs) have an important role in the activation of macrophages directly acting on the molecules secreted by these cells. Little is known about the role of these secreted molecules on the survival control of activated T lymphocytes (

6. Uma proposta de controle neural adaptativo para a navegação de veículos autônomos / Autonomous vehicle navigation control: an adaptative neural networks proposal
Os equipamentos robóticos foram inicialmente criados para atuarem em ambientes industriais fechados. Com o passar do tempo, melhorias foram conquistadas. Atualmente, não se limitam mais à realização de tarefas simples e repetitivas em locais especialmente preparados. Novos equipamentos, capazes de atuarem em ambientes abertos e de realizarem as mais div

7. A influência de atributos físicos na formação de primeiras impressões: uso do TAT e impacto no processo decisório de profissionais de recursos humanos / The effect of physical attributes in the first impressioni nformation: use of Thematic Apperception Test (TAT) and impact in decision-making of human resources employees
The present study intends to verify the effect of physical attributes in decision-making under uncertainty conditions. Facial hair has an important role in the evolutionary history of Homo sapiens with an adaptative value in the ancestor environment. This feature could have been selected in the sexual selection context for intrasexual or intersexual selectio

8. ParÃmetros de normalidade do sistema imunolÃgico no idoso em Fortaleza - Cearà / The immune system normal parameters in elderly people in Fortaleza Ceara
Worldwide, the number of individuals whose age is over 60 years will grow exponentially. Is provided an increase of 694 million in the number of older people in 2025. Ageing is a complex process that negatively impacts the development of the immune system and its ability to function. Immunosenescence is a multifactorial condition leading to many pathological

9. AVALIAÇÃO DA ATIVIDADE DE ECTONUCLEOTIDASES NO CÓRTEX CEREBRAL E PLAQUETAS DE RATOS EXPOSTOS À FUMAÇA DE CIGARRO
Inflammatory and degenerative pathophysiological processes within the central nervous system (CNS) and platelets are important causes of human disease promoted by cigarette smoke. The objective of the present study was to evaluate activity of the enzymes that hydrolyze nucleotides and nucleosides in synaptosomes of cerebral cortex and platelets from rats exp

10. Physical training, inflammatory process and adaptative condition / Treinamento fisico, processo inflamatorio e adaptação
Physical exercise can cause trauma to biological structures as skeletal muscle, joints, bone and several other tissues. Training in a chronic way and considering training-recovery relationship can lead to a coherent sequence of trauma and consequently to organic adaptive condition (Functional Overreaching - FOR). On the other hand an imbalance between traini

11. Resistência fisiológica e comportamental de populações de Sitophilus zeamais à permetrina, esfenvalerato e esfenvalerato + fenitrotiona / Physiological and behavioral resistance of populations of Sitophilus zeamais to permethrin, esfenvalerate and esfenvalerate + fenitrothion
The maize weevil, Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae) is considered the main pest of stored maize in Brazil and its control is achieved mainly by insecticides. The massive and intensive use of these compounds may lead to selection of resistant populations and consequently compromise the control efficacy of this insect pest in Bra

12. Association of hypotalamic POMC, NPY and IRS2 with feeding behavior in norma and overweight Wistar rats / Associação do PMOC, NPY e IRS2 hipotalâmicos com padrões de comportamento alimentar em ratos wistar normais e sobrepeso
The feeding behavior of a specie is determined by a group of phylogenetic, ontogenetic, and epigenetic features, and regulated by internal and external factors to the organism. The natural phenomena that govern life in our planet are mainly periodic, and the food stocks is not an exception. Each harvest is followed by a time between harvests, and this rhythm
