1. Physiological Responses of Slow-Growing Chickens under Diurnally Cycling Temperature in a Hot Environment
ABSTRACT Free-range chicken production has significantly increased in recent years and it often entails exposing birds to cyclic environmental conditions. The objective of the current study was to investigate the effect of bird strain and sex, and rearing system on the physiological responses of Potchefstroom Koekoek (PK), Ovambo (OV) and Naked Neck (NN) chi

2. Experimental infection with the Toxoplasma gondii ME-49 strain in the Brazilian BR-1 mini pig is a suitable animal model for human toxoplasmosis
Toxoplasma gondii causes toxoplasmosis, a worldwide disease. Experimentation with pigs is necessary for the development of new therapeutic approaches to human diseases. BR-1 mini pigs were intramuscularly infected with T. gondii with tachyzoites (RH strain) or orally infected with cysts (ME-49 strain). Haematology and serum biochemistry were analysed and buf

4. Uso de microorganismos promotores de crescimento como tecnologia para incrementar a produção de madeira e sequestro de carbono de Schizolobium amazonicum Huber ex Ducke (Paricá) em condições de campo
Schizolobium amazonicum Heber ex Ducke occurs naturally in Amazon and presents huge commercial importance due to its rapid growth and excellent performance on cropping systems a fact that has been raising much interest in the study of new strategies to increase more efficiently the wood yield. The use of soil microorganisms and its growth-promoting potent

5. Effect of praziquantel administration on hepatic stereology of mice infected with Schistosoma mansoni and fed a low-protein diet
A study was undertaken to investigate the effect of administering praziquantel (PZQ), focusing on the liver stereological findings of malnourished mice infected with Schistosoma mansoni. Thirty female Swiss Webster mice (age: 21 days; weight: 8-14 g) were fed either a low-protein diet (8%) or standard chow (22% protein) for 15 days. Five mice in each group w

6. Spontaneous stage differentiation of mouse-virulent Toxoplasma gondii RH parasites in skeletal muscle cells: an ultrastructural evaluation
Although the predilection for Toxoplasma gondii to form cysts in the nervous system and skeletal and heart muscles has been described for more than fifty years, skeletal muscle cells (SkMCs) have not been explored as a host cell type to study the Toxoplasma-host cell interaction and investigate the intracellular development of the parasite. Morphological asp

7. Apoptose e proliferação celular em células trofoblásticas (linhagem BeWo) são diferentemente moduladas pelas cepas de Toxoplasma gondii
Transplacental transmission causes one of the most severe forms of infection with protozoan parasite Toxoplasma gondii. The ability of the parasite to survive intracellularly largely depends on the blocking of different proapoptotic signaling cascade of its host cell. However, alterations in the incidence of apoptosis, during pregnancy, are associated with a

8. Avaliação do papel da galectina-3 sobre funções de neutrófilos durante a infecção por cepa virulenta RH de Toxoplasma gondii em camundongos C57BL/6
Galectins are beta-galactoside-binding animal lectins involved in several biological processes, and Gal-3 has been related to modulation of immune reactions and inflammatory responses. The present study aimed to evaluate the influence of Gal-3 in neutrophil viability, early apoptosis and cell death in parallel with its biological functions after in vivo and

9. DESENVOLVIMENTO E VALIDAÇÃO DE MÉTODO CROMATOGRÁFICO PARA AVALIAÇÃO DE POTÊNCIA DE ERITROPOIETINA HUMANA RECOMBINANTE. CORRELAÇÃO COM O ENSAIO BIOLÓGICO / DEVELOPMENT AND VALIDATION OF CHROMATOGRAPHIC METHOD FOR THE POTENCY ASSESSMENT OF RECOMBINANT HUMAN ERYTHROPOIETIN. CORRELATION WITH THE BIOLOGICAL ASSAY
Erythropoietin is a glycoprotein which stimulates the erythropoiesis, clinically used for the treatment of renal anaemia. The biological and chromatographic methods for the potency evaluation of recombinant human erythropoietin (rhEPO) in pharmaceutical products were validated in the present work. The normocythaemic mice bioassay was carried out in female BA

10. EFEITO DO NEMATÓIDE ENTOMOPATOGÊNICO Steinernema glaseri (STEINER, 1929) (RHABDITIDA: STEINERNEMATIDAE) ISOLADO SANTA ROSA SOBRE OS PARÂMETROS BIOLÓGICOS DE NINFAS INGURGITADAS DE Amblyomma cajennense (FABRÍCIUS, 1787) (ACARI: IXODIDAE)
Amblyomma cajennense (Fabrícius, 1787) (Acari: Ixodidade) is an ectoparasitic kind of horse, widely distributed in south and central America. The indiscriminate use of acaricidal has taken this animals population to a critical resistence situation to drugs and the exclusive use of acaricidal is just viable in pratical and economical terms became necessary t

11. Detection of Toxoplasma gondii DNA in sera samples of mice experimentally infected
Detection of Toxoplasma gondii (T. gondii) DNA in blood can help to diagnose the disease in its acute phase; however, it must be considered that hemoglobin, present in blood, can inhibit polymerase activity, making impracticable the detection of DNA in samples. Mice were experimentally infected via oral route with ME49 and BTU2 strains cysts and RH strain ta

12. Analysis diferential gene expression of skeletal muscular cells from a primary culture infected with tackyzoites of toxoplasma gondii. / Análise diferencial da expressão gênica de cultura primária de células musculares esqueléticas durante a infecção com taquisoítos de toxoplasma gondii.
The microarray technique is a powerful tool to analyze the changes in gene expression occurring during an infectious process caused by a pathogen. This work aims to study the biological process of interaction between a host cell and an intracellular parasite, Toxoplasma gondii, at a transcriptional level, using a high density microarray (Genechip) Samples we
