25. Avaliação da indiferenciação celular e indução de neurodiferenciação em co-cultivo de fibroblastos NIH 3T3 com células mononucleares do sangue de cordão umbilical
Cellular therapy represent a new frontier for the treatment of several diseases, including diseases related to central nervous system. Human umbilical cord blood is an attractive source of stem cells; however, it has a heterogeneous population with a small amount of mesenchymal stem cells. Currently, cell reprogramming induced by different methodologies can

26. Technological, physicochemical and sensory characteristics of a Brazilian semi-hard goat cheese (coalho) with added probiotic lactic acid bacteria
Over the past few years, the use of probiotics, which are capable of exerting beneficial effects on the composition of intestinal microbiota, has increased. Cheeses have been suggested as a better carrier of probiotic bacteria than other fermented milk products. The effect of added cultures of probiotic lactic acid bacteria on the quality of a Brazilian goat

27. M2-polarized macrophages promote metastatic behavior of Lewis lung carcinoma cells by inducing vascular endothelial growth factor-C expression
OBJECTIVES: Tumor-associated macrophages that generally exhibit an alternatively activated (M2) phenotype have been linked to tumor progression and metastasis. However, the role of M2-polarized macrophages in the growth and metastasis of lung adenocarcinoma remains enigmatic. The aim of this study was to explore the effect of M2 macrophages on the proliferat

28. Co-culture of apoptotic breast cancer cells with immature dendritic cells: a novel approach for DC-based vaccination in breast cancer
A dendritic cell (DC)-based vaccine strategy could reduce the risk of recurrence and improve the survival of breast cancer patients. However, while therapy-induced apoptosis of hepatocellular and colorectal carcinoma cells can enhance maturation and antigen presentation of DCs, whether this effect occurs in breast cancer is currently unknown. In the present

29. Fibroblastos gengivais humanos em co-cultura com Aggregatibacter actinomycetemcomitans lisogênico induzem a liberação de fago / Human gingival fibroblasts in co-culture with Aggregatibacter actinomycetemcomitans lysogenic induces the release of phage
A relação entre bacteriófagos e virulência bacteriana é um modelo muito intrigante e pouco estudado na patogênese periodontal, uma vez que um patógeno periodontal pode ser lisogênico. O objetivo do nosso estudo é determinar a capacidade de fibroblastos gengivais humanos de induzir as cepas lisogênicas de Aggregatibacter actinomycetemcomitans. Dois

30. INFLUÊNCIA DA INTERAÇÃO FOLICULAR, DO FLUIDO FOLICULAR E DO FATOR DE CRESCIMENTO SEMELHANTE À INSULINA II (IGF-II) NO DESENVOLVIMENTO IN VITRO DE FOLÍCULOS PRÉ-ANTRAIS ISOLADOS CAPRINOS / INFLUENCE OF INTERACTION FOLLICULAR, FOLLICLE FLUID AND GROWTH FACTOR LIKE INSULIN II (IGF-II) IN VITRO DEVELOPMENT OF ISOLATED PREANTRAL FOLLICLES GOATS
A presente tese foi realizada em três fases. A fase I teve por objetivo avaliar a interação folicular pré-antral quando estes eram cultivados com 1 ou 3 folículos/gota na presença ou ausência do hormônio folículo estimulante recombinante (rFSH 1000ng/ml) ou ainda, co-cultivados com folículos antrais caprinos. Na fase II, foi verificada a influênci

31. Synergistic growth effect among bacteria recovered from root canal infections
The objective of this study was to determine the ecological relationships between bacterial species that colonize infected root canals. Root canal bacteria recovered from one patient with pulp canal necrosis were evaluated in vitro for synergistic and antagonistic activities determined by mono and co-culture growth kinetics and the production of bacteriocin-

32. Can thymic epithelial cells be infected by human T-lymphotropic virus type 1?
The human T-lymphotropic virus type-1 (HTLV-1) is the cause of adult T cell leukaemias/lymphoma. Because thymic epithelial cells (TEC) express recently defined receptors for the virus, it seemed conceivable that these cells might be a target for HTLV-1 infection. We developed an in vitro co-culture system comprising HTLV-1+-infected T cells and human TECs. I

33. A performance study of simultaneous microbial removal of no and SO2 in a biotrickling-filter under anaerobic condition
The behaviors of simultaneous removal of NO and SO2 using the coculture of anaerobic denitrifying bacteria and sulfate reducing bacteria was investigated in a bench-scale biotrickling-filter. When the combined NO/SO2 removal biotrickling-filter was operated at an empty bed residence time of 76 s with NO and SO2 feed concentrations of 2 and 2 g/m3, respective

34. Co-culture of chondrocytes and bone marrow mesenchymal stem cells in vitro enhances the expression of cartilaginous extracellular matrix components
Chondrocytes and bone marrow mesenchymal stem cells (BMSCs) are frequently used as seed cells in cartilage tissue engineering. In the present study, we determined if the co-culture of rabbit articular chondrocytes and BMSCs in vitro promotes the expression of cartilaginous extracellular matrix and, if so, what is the optimal ratio of the two cell types. Cult

35. Agrobacterium-mediated genetic transformation of 'Hamlin' sweet orange.
The development and optimization of efficient transformation protocols is essential in new citrus breeding programs, not only for rootstock, but also for scion improvement. Transgenic 'Hamlin' sweet orange (Citrus sinensis (L.) Osbeck) plants were obtained by Agrobacterium tumefaciens-mediated transformation of epicotyl segments collected from seedlings germ

36. Production of angkak through co-culture of Monascus purpureus and Monascus ruber
Angkak (red mold rice, red yeast rice, Chinese red rice) is a traditional Chinese medicine produced by solid-state fermentation of cooked non-glutinous rice with Monascus species. The secondary metabolite of Monascus species, monacolin K /lovastatin, has been proven to lower blood lipid levels. In this study, a co-culture of Monascus purpureus MTCC 369 and M
