1. Kinetic modeling and evaluation of free radical-scavenging behavior in oils: application to four tropical and subtropical fruits in a DPPH system
Abstract A kinetic model was developed to represent the radical-scavenging capacity (RSC) for the oxidation of oils. The model was developed using second-order rate constants (k2) to represent the RSC. The RSC of the oils can be compared by the k2 values indicating their scavenging capacity. Furthermore, the k2 values can be used to determine the decay kinet

3. Isolation and characterization of mesenchymal stem/stromal cells from Ctenomys minutus
Abstract Mesenchymal stem/stromal cells (MSCs) are multipotent cells distributed in all tissues and characterized by adherence, morphology, immunophenotype and trilineage differentiation potential. The present study aimed to isolate and characterize adherent MSC-like populations from different tissues of Ctenomys minutus, a threatened wildlife rodent popular

4. Repair of bone defects using adipose-derived stem cells combined with alpha-tricalcium phosphate and gelatin sponge scaffolds in a rat model
Abstract Objectives This study aimed to evaluate the potential of adipose-derived stem cells (ASCs) combined with a modified α-tricalcium phosphate (α-TCP) or gelatin sponge (GS) scaffolds for bone healing in a rat model. Material and Methods Bone defects were surgically created in the femur of adult SHR rats and filled with the scaffolds, empty or com

5. Papel das células-tronco mesenquimais autólogas em comparação com plasma rico em plaquetas na cicatrização de feridas cutâneas em camundongos diabéticos
Resumo: Lesões cutâneas crônicas afetam 15% dos pacientes diabéticos e humanos representam um risco 15 a 46 vezes maior de amputações de membros em comparação com as pessoas com a glicemia normal. Supõe-se que a metade destas amputações poderia ser evitada por meio do tratamento precoce das feridas cutâneas com, por exemplo, uma adequada terapia

6. Human mesenchymal stem cells are resistant to cytotoxic and genotoxic effects of cisplatin in vitro
Abstract Mesenchymal stem cells (MSCs) are known for their important properties involving multilineage differentiation potential., trophic factor secretion and localization along various organs and tissues. On the dark side, MSCs play a distinguished role in tumor microenvironments by differentiating into tumor-associated fibroblasts or supporting tumor grow

7. Ensaio clínico prospectivo randomizado sobre terapia com células mononucleares da medula óssea para cardiomiopatia dilatada idiopática: INTRACELL
Objetivo: Testamos a hipótese de que a injeção intramiocárdica direta de células mononucleares de medula óssea em pacientes portadores de cardiomiopatia dilatada não-isquêmica pode melhorar a função ventricular e a capacidade física. Métodos: Trinta pacientes com cardiomiopatia dilatada não isquêmica e fração de ejeção 35% foram randomiz

8. Genetics and sport performance: current challenges and directions to the future
In recent years there has been a great progress in molecular biology techniques, which has facilitated the researches on influence of genetics on human performance. There are specific regions of DNA that can vary between individuals. Such variations (i.e., polymorphisms) may, in part, explain why some individuals have differentiated responses to certain stim

9. Terapia gênica com fator de crescimento endotelial vascular 165 para pacientes com angina refratária: mobilização de células progenitoras endoteliais
FUNDAMENTO: O fator de crescimento endotelial vascular (VEGF - vascular endothelial growth factor) induz a mobilização de células progenitoras endoteliais (CPEs) com capacidade de proliferação e diferenciação em células endoteliais, contribuindo, dessa forma, para o processo angiogênico. OBJETIVO: Buscamos avaliar o comportamento de CPEs em paciente

11. Monetary policy and the cross-section of stock returns: a FAVAR approach
We use a factor-augmented vector autoregression (FAVAR) to estimate the impact of monetary policy shocks on the cross-section of stock returns. Our FAVAR combines unobserved factors extracted from a large set of nancial and macroeconomic indicators with the Federal Funds rate. We nd that monetary policy shocks have heterogeneous e ects on the crosssection

12. Treatment of critical defects produced in calvaria of mice with mesenchymal stem cells
As células-tronco mesenquimais (MSC) estão presentes em nichos especializados nas regiões perivasculares dos tecidos adultos e são capazes de se diferenciar em diversos tipos celulares, dentre eles, os comprometidos com processos de reparação óssea. MSC oriundas da medula óssea de oito camundongos jovens C57BL/6 gfp+ foram expandidas em culturas e ut
