13. Diferenciação de células tronco mesenquimais a partir do meio condicionado da linhagem HepG2
OBJETIVO: Examinar o efeito do meio condicionado da linhagem HepG2 nas célulastronco mesenquimais in vitro no que se refere à sua diferenciação em hepatócito. MATERIAIS E MÉTODOS: As CTM foram isoladas da medula óssea de ratas Wistar combinando a centrifugação por gradiente de densidade e a aderência à superfície de cultivo. As CTM foram cultivad

14. DEVELOPMENT OF FLOW PROCEDURES INVOLVING SOLID-PHASE REACTOR AND ANALYTICAL MICROSYSTEM CONSTRUCTED WITH LTCC (LOW TEMPERATURE CO-FIRED CERAMICS) TO DETERMINATION OF ANALYTES OF PHARMACEUTICAL INTEREST / Desenvolvimento de procedimentos em fluxo envolvendo reatores em fase sólida e microssistema analítico construído com LTCC (Low Temperature Co-fired Ceramics) para a determinação de analitos de interesse farmacêutico
The employment of flow injection systems to determination of N-acetylcysteine, captopril, dipyrone and fluoxetine hydrochloride in pharmaceutical formulations was investigated. The N-acetylcysteine was determinated employing a solid-phase reactor containing Zn3(PO4)2 immobilized in a polyester resin coupled to a flow injection system. The procedure was based

15. Petroleum ether extract of Cissus quadrangularis (LINN) stimulates the growth of fetal bone during intra uterine developmental period: a morphometric analysis
OBJECTIVE: The aim of the present study was to analyze the effect Cissus quadrangularis plant petroleum ether extract on the development of long bones during the intra-uterine developmental stage in rats. METHODS: Pregnant rats (n=12) were randomly assigned into either a control group (n=6) or a Cissus quadrangularis treatment (n=6) group. Pregnant rats in t

16. Solid sampling analysis by flame atomic absorption spectrometry for lead determination in seawater samples after pre-concentration using cocrystallized alizarin red - naphthalene
Um dispositivo para a amostragem direta de sólidos por espectrometria de absorção atômica com chama (DSA-FAAS) é proposto para a determinação de chumbo em água, após o procedimento de extração em fase sólida. Uma solução tampão, NH4Cl-NH3, pH 8,1, e a fase sólida (vermelho de alizarina adsorvido em naftaleno) foram adicionados a amostra de á

17. Relationships between fetal body weight of Wistar rats at term and the extent of skeletal ossification
We investigated the relationship between fetal body weight at term (pregnancy day 21) and the extent of ossification of sternum, metacarpus, metatarsus, phalanges (proximal, medial and distal) of fore- and hindlimbs and cervical and coccygeal vertebrae in Wistar rats. The relationships between fetal body weight and sex, intrauterine position, uterine horn, h

18. Copper, zinc and manganese determination in saline samples employing faas after separation and preconcentration on Amberlite XAD-7 and Dowex 1x-8 loaded with Alizarin Red S
Dois procedimentos foram comparados para separação e pré-concentração de traços de cobre, zinco e manganês em amostras salinas. Os métodos basearam-se na adsorção dos íons metálicos sobre duas fases sólidas obtidas por impregnação de uma resina não-iônica Amberlite XAD-7 e uma resina aniônica Dowex 1X8-50 com o reagente vermelho de alizarin

19. Determinação de Mn, Cu e Zn em matrizes salinas após separação e pré-concentração usando Amberlite XAD-7 impregnada com Vermelho de Alizarina S
The aim of this work was to explore the possibility of the application of a non-ionic resin obtained by impregnation of Alizarin Red S (VAS) in Amberlite XAD-7 for manganese, copper and zinc separation and preconcentration in saline matrices. For these system, the metals were quantitatively retained, in the pH range 8.5-10.0, by using 0.50 g of solid phase,

20. Potencialidade do vermelho de Alizarina S impregnado em resinas para separação e pré-concentração de Cu, Zn e Mn em matrizes salinas.
The flame atomic absorption spectrometric (FAAS) determination of trace metal ions in high saline samples, such as seawater and brine, is difficult due to various factors, particularly the low level of metal content and the high salt content of the matrix. Thus, trace determination in saline solutions always needs a prior separation and preconcentration meth

21. Determinação espectrofotométrica de aspartame em adoçantes por injeção em fluxo usando um reator em fase sólida contendo fosfato de zinco imobilizado
A flow injection spectrophotometric method was developed for determining aspartame in sweeteners. Sample was dissolved in water and 250 µL of the solution was injected into a carrier stream of 5.0 x 10-5 mol L-1 sodium borate solution. The sample flowed through a column (14 cm x 2.0 mm) packed with Zn3(PO4)2 immobilized in a polymeric matrix of polyester re

22. Dual staining of corneal endothelium with trypan blue and alizarin red S: importance of pH for the dye-lake reaction.
Evaluation of corneal endothelial integrity by combined staining with the vital stain trypan blue and the intercellular stain alizarin red S provides a simple, quick technique for visualisation of both damaged and normal cells, thereby permitting the quantification of endothelial cell damage. Adjustment of the pH of the alizarin red S reagent to 4.2 is impor

24. Alendronate Enhances Osteogenic Differentiation of Bone Marrow Stromal Cells: A Preliminary Study
Alendronate inhibits osteoclastic activity. However, some studies suggest alendronate also has effects on osteoblast activity. We hypothesized alendronate would enhance osteoblastic differentiation without causing cytotoxicity of the osteoblasts. We evaluated the effect of alendronate on the osteogenic differentiation of mouse mesenchymal stem cells. D1 cell
