1. Characterization of additives in NR formulations by TLC-IR (UATR)
Abstract It is a well-established fact that rubber accelerator is essential to provide solution in different sectors. However, there is a reversal process which can reduce the material performance. Sulfur accelerators donors and organic peroxides have been presented as a solution to the problem. The methodology development that can separate or characterize

2. Effects of 5-aza-2′deoxycytidine on RECK gene expression and tumor invasion in salivary adenoid cystic carcinoma
Reversion-inducing cysteine-rich protein with kazal motifs (RECK), a novel tumor suppressor gene that negatively regulates matrix metalloproteinases (MMPs), is expressed in various normal human tissues but downregulated in several types of human tumors. The molecular mechanism for this downregulation and its biological significance in salivary adenoid cystic

3. Organisation perverse ou le pacte avec le Diable
It is uncertain to characterize a perverse personality, defined as structure. It may seem even more daring to consider a group as perverse and a fortiori to extend to an organization. Some recurring operations are related to this perversion: instrumentality of others, reversal, negation of otherness. How to draw the line between pathology or deviance, betwee

4. Effect of curcumin on human colon cancer multidrug resistance in vitro and in vivo
OBJECTIVE: To determine whether curcumin reverses the multidrug resistance of human colon cancer cells in vitro and in vivo. METHODS: In a vincristine-resistant cell line of human colon cancer, the cell viability of curcumin-treated cells was determined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Rhodamine123 efflux was e

5. Contrast sensitivity of pattern transient VEP components: contribution from M and P pathways
The purpose of this study was to compare contrast sensitivity estimated from transient visual evoked potentials (VEPs) elicited by achromatic pattern-reversal and pattern-onset/offset modes. The stimuli were 2-cpd, achromatic horizontal gratings presented either as a 1 Hz pattern reversal or a 300 ms onset/700 ms offset stimulus. Contrast thresholds were est

6. Imunoproteção de ilhotas pancreáticas microencapsuladas em biomateriais inovadores e seu potencial terapêutico no diabetes mellitus tipo 1 / Immunoprotection of pancreatic islets microencapsulated in inovative biomaterials and its therapeutic potential in type 1 Diabetes Mellitus
Transplantation of microencapsulated islets represents an attractive therapeutical approach to treat type 1 Diabetes Mellitus, accounting for an improved glycemic control and the abolishment of immunosuppressive therapies. However, maintenance of long-term β-cell viability remains a major problem. During islet isolation, the loss of extracellular matrix

8. Expression of IGF-II, IGF-IR, SF-1 and DAX-1 genes in pediatric and adult adrenocortical tumors / Expressão dos genes IGF-II, IGF-IR, SF-1 e DAX-1 em tumores adrenocorticais de crianças e adultos
Introduction: The molecular pathogenesis of adrenocortical tumors is heterogeneous and incompletely understood. Insulin-like growth factor II (IGF-II) overexpression has been demonstrated in adult adrenocortical carcinomas. IGF-II exerts its mitogenic effects through interaction with IGF-I receptor (IGF-IR). In addition, steroidogenic factor 1 gene (SF-1) an

9. Determinação de temperatura de chama por espectroscopia de emissão
A espectroscopia de emissão foi empregada na determinação da temperatura de chamas pré-misturadas de GLP (Gás Liqüefeito de Petróleo). Foi investigada a emissão natural dos radicais OH*, C2* e CH* em chamas apresentando três diferentes condições de queima: razão equimolar combustível/comburente (chama estequiométrica), excesso de combustível (

10. Medições de temperaturas de chamas de etanol utilizando fluorescência induzida por laser / Temperature Measurements in Ethanol Flames Using Laser Induced Fluorescence
Conventional methods for the study of combustion are usually intrusive methods (for example, the use of thermocouples to measure flame temperatures), which might disturb the burning process (thermal, catalytic or aerodynamic effects). The diagnostics techniques using lasers, in addition to being non-intrusive, have high temporal and spatial resolution. They

11. Avaliação "in vivo" e "in vitro" da resistencia a multiplas drogas
Multidrug resistance has been one of the most active research areas during last decade because its growing clinical importance. Expression of the MDR1 (170-Pglycoprotein) gene is an active effux pump that decreases the intracellular accumulation of some of the major anticancer drugs such as anthracyclines, vinca alkaloids, and epipodophyllotoxins. Our study
