Impacts of climate changes on crop physiology and food quality
(ELSEVIER SCIENCE BV, 2010)
Carbon emissions related to human activities have been significantly contributing to the elevation of atmospheric [CO(2)] and temperature. More recently, carbon emissions have greatly accelerated, thus much stronger effects ...
Multipotent stem cells from umbilical cord: Cord is richer than blood!
(ALPHAMED PRESS, 2008)
The identification of mesenchymal stem cell ( MSC) sources that are easily obtainable is of utmost importance. Several studies have shown that MSCs could be isolated from umbilical cord (UC) units. However, the presence ...
Gene Expression Profile of Mesenchymal Stem Cells from Paired Umbilical Cord Units: Cord is Different from Blood
(SPRINGER HEIDELBERG, 2009)
Mesenchymal stem cells (MSC) are multipotent cells which can be obtained from several adult and fetal tissues including human umbilical cord units. We have recently shown that umbilical cord tissue (UC) is richer in MSC ...
Effect of the immunosuppressants on hepatocyte proliferation and apoptosis in a young animal model of liver regeneration: An immunohistochemical study using tissue microarrays
(BLACKWELL PUBLISHING, 2008)
Hepatocyte proliferation and apoptosis (programmed cell death) occur during the liver parenchyma regeneration and the liver size modeling is mainly controlled by hepatocyte apoptosis. The purpose of the present study was ...
Effects of Low-Level Laser Therapy on Collagen Expression and Neutrophil Infiltrate in 5-Fluorouracil-Induced Oral Mucositis in Hamsters
(WILEY-LISS, 2010)
Background and Objectives: Several studies have suggested that low-level laser therapy (LLLT) can ameliorate oral mucositis, however, the mechanisms involved are not well understood. The aim of this study was to investigate ...
Cyclooxygenase-2 and vascular endothelial growth factor expression in 5-fluorouracil-induced oral mucositis in hamsters: evaluation of two low-intensity laser protocols
(SPRINGER, 2009)
The aim of this study was to investigate the mechanisms whereby low-intensity laser therapy may affect the severity of oral mucositis. A hamster cheek pouch model of oral mucositis was used with all animals receiving ...
Histopathology and laser autofluorescence of ischemic kidneys of rats
(SPRINGER LONDON LTD, 2009)
The purpose of this research was to evaluate the severity of renal ischemia/reperfusion injury as determined by histology and by laser-induced fluorescence (LIF) with excitation wavelengths of 442 nm and 532 nm. Wistar ...
Renal ischemia in rats: Mitochondria function and laser autofluorescence
(ELSEVIER SCIENCE INC, 2008)
Ischemia-reperfusion injury is the major cause of organ dysfunction or even nonfunction following transplantation. It can attenuate the long-term survival of transplanted organs. To evaluate the severity of renal ischemia ...
Clove and eugenol in noncytotoxic concentrations exert immunomodulatory/anti-inflammatory action on cytokine production by murine macrophages
(WILEY-BLACKWELLMALDEN, 2012)
Objectives The extract and essential oil of clove (Syzygium aromaticum) are widely used because of their medicinal properties. Eugenol is the most important component of clove, showing several biological properties. Herein ...
Queimadas de cana-de-açúcar: Avaliação de efeitos na qualidade do ar e na saúde respiratória de crianças
(Instituto de Estudos Avançados da Universidade de São Paulo, 2010)
Pesquisa em Espírito Santo do Turvo (SP) analisou poluição atmosférica causada por queima de cana-de-açúcar e saúde respiratória de crianças. Realizaram-se medições de PM10, PTS e NO2, durante safra, em 2004 e 2005, em ...
