13. Ecologia e Conservação de Tartarugas Marinhas Através da Análise de Encalhes no Litoral Paraibano
Five sea turtle species use the Brazilian coast for reproduction and feeding: loggerhead turtle (Caretta caretta), green turtle (Chelonia mydas), leatherback turtle (Dermochelys coriacea), olive turtle (Lepidochelys olivacea) and hawksbill turtle (Eretmochelys imbricata). These species are included in the threatened categories, as much globally, according to

14. Efeito da aclimatação a altas temperaturas em suínos selecionados para consumo residual / Effect of acclimation to high ambient temperature of pigs selected for residual feed intake
Thirty-six Large White castrate males belonging to two divergent lines in residual feed intake, with average initial body weight of 50.5 0.9 kg and approximately 92 days of age, were used to evaluate the effects of acclimation to high temperature on the performance, thermoregulatory responses and blood parameters of pigs divergently selected for low and high

15. Modelos para a produção de eritropoietina recombinante humana in vivo e in vitro com vetores plasmideais em ovinos / Models for the production of human recombinant erythropoietin in vivo and in vitro with plasmidial vectors in ovine
Some post-translational modifications are necessary for the production of biopharmaceutical proteins, such as recombinant human erythropoietin (rhEPO), with a good specific action and a high biological activity. These modifications are obtained only by bioreactors based on eukaryotic cell as mammary cells. Bioreactors, in vivo or in vitro, with this kind of

16. Production of reactive oxygen (H2O2) and nitrogen (NO) intermediates and TNF-α in mice genetically selected for high (H) and low (L) antibody response and experimentally infected with Leptospira serovar pomona
The aim of the present study was to evaluate the activity of macrophages, and the production of TNF-α and antibodies against experimental infection by Leptospira serovar Pomona in mice genetically selected for High (H) or Low (L) humoral immune response. To evaluate macrophagic activity, peritoneal and splenic lavages were performed for determination of oxy

17. Genotoxic potential of Cotinus coggygria Scop. (Anacardiaceae) stem extract in vivo
The intention was to evaluate the possible in vivo genotoxic potential in different cell-types, of a methanol extract obtained from the plant stem of Cotinus coggygria Scop., using the sex-linked recessive lethal (or SLRL) test and alkaline comet assay. The SLRL test, revealed the genotoxic effect of this extract in postmeiotic and premeiotic germ-cell lines

18. Panic-like behaviors in Carioca High-and Low-conditioned Freezing rats
Panic disorder involves both recurrent unexpected panic attacks and persistent concern about having additional attacks. Electrical stimulation of the dorsal periaqueductal gray (dPAG) is an animal model of both panic attack and panic disorder, whereas contextual fear conditioning represents a model of anticipatory anxiety. Previous research indicated that an

19. Análise fractal da vascularização da membrana corioalantóide de embriões de codornas japonesas (Coturnix japonica submetidas a campo eletromagnético de 60 Hz.
The formation of vascular network is governed mainly by two processes, vasculogenesis and angiogenesis. In vasculogenesis, the angioblastic which are the precursors of endothelial cells arising in germ layer (mesoderm) of the yolk sac (outside the embryo body). These angioblastic organize themselves to form blood islands, differing in blood vessels where the

20. Cryptococcus neoformans var. grubii - Pathogenicity of environmental isolates correlated to virulence factors, susceptibility to fluconazole and molecular profile
The pathogenicity of Cryptococcus neoformans is heterogeneous and is associated with the expression of virulence factors. This study aimed to correlate the pathogenicity of C. neoformans var. grubii in BALB/c mice with in vitro virulence factors, fluconazole minimal inhibitory concentrations (MICs) and molecular profiles, before and after animal passage.

21. Influence of bisphosphonates on alveolar bone density: a histomorphometric analysis
This study is a histomorphometrical analysis of the influence of the bisphosphonate alendronate on alveolar bone density. Eighteen male Wistar rats were randomly assigned to a control group (n = 9) that received no medication and an experimental group (n = 9) that received oral alendronate (1 mg/kg) from birth until euthanization at 3 months of age. Semi-ser

22. Repeated exposure of adolescent rats to oral methylphenidate does not induce behavioral sensitization or cross-sensitization to nicotine
Several lines of evidence indicate that the use of stimulant drugs, including methylphenidate (MPD), increases tobacco smoking. This has raised concerns that MPD use during adolescence could facilitate nicotine abuse. Preclinical studies have shown that repeated treatment with an addictive drug produces sensitization to that drug and usually cross-sensitizat

23. Estudo dos efeitos da terapia fotodinâmica na progressão tumoral e em modelos celulares tridimensionais / Study of the effects of photodynamic therapy on tumor progression and in three-dimensional cellular models.
Melanoma is the type of skin cancer with poor prognosis due to its high probability of suffering metastases. Currently there are few effective treatments for the this, and the survival of patients with metastases is very low, around 8 months, with cure rates of these conditions do not exceed 1%. Photodynamic therapy (PDT) is a therapeutic modality selective

24. AVALIAÇÃO DE DOIS SISTEMAS FORRAGEIROS SOB PASTEJO COM VACAS LEITEIRAS / TWO BASED-PASTURE SYSTEMS EVALUATION UNDER GRAZING WITH DAIRY COWS
The objective of this work was evaluate two pasture-based systems (PS) with elephantgrass (Pennisetum purpureum Schum.), ryegrass (Lolium multiflorum Lam.), and spontaneous growth species varying in one system, the mixture with white clover (Trifolium repens L.) and, in the other system, with forage peanut (Arachis pintoi Kraprov &Gregory), handled under rot
