Phototoxic effect of curcumin on methicillin-resistant Staphylococcus aureus and L929 fibroblasts
(2013-02-01)
Photodynamic therapy has been investigated as an alternative method of killing pathogens in response to the multiantibiotic resistance problem. This study evaluated the photodynamic effect of curcumin on methicillin-resistant ...

Comparative experimental infection of Lacazia loboi in BALB/c and B10.A mice
(2003-06-01)
Both hind foot pads of BALB/c and B10.A mice strains, were inoculated with a fungal suspension of Lacazia loboi obtained from a Jorge Lobo's disease patient. The suspension had 9 × 105 cells/ml and its viability index was ...
GROWTH AND FERMENTATION CHARACTERISTICS OF NEW SELECTED STRAINS OF SACCHAROMYCES AT HIGH-TEMPERATURES AND HIGH CELL DENSITIES
(Wiley-Blackwell, 1991-03-15)
Maintenance of high cell viability was the main characteristic of our new strains of thermotolerant Saccharomyces. Total sugar conversion to ethanol was observed for sugarcane juice fermentation at 38-40-degrees-C in less ...
Direct observation of oxidative stress on the cell wall of Saccharomyces cerevisiae strains with atomic force microscopy
(Kluwer Academic Publ, 1999-11-01)
We imaged pores on the surface of the cell wall of three different industrial strains of Saccharomyces cerevisiae using atomic force microscopy. The pores could be enlarged using 10 mM diamide, an SH residue oxidant that ...
Kinetics of B cell response during Yersinia enterocolitica infection in resistant and susceptible strains of mice
(Taylor & Francis Inc, 2007-01-01)
In this study we analyze the B-cell response in murine yersiniosis. To this end, we determined whether polyclonal activation of B-lymphocytes occurs during infection of susceptible (BALB/c) and resistant (C57BL/6) mice ...
Effects of mutations in acetate metabolism on high-cell-density growth of Escherichia coli
(Nature America Inc, 2000-06-01)
To study the role played by acetate metabolism during high-cell-density growth of Escherichia coli cells, we constructed isogenic null mutants of strain W3100 deficient for several genes involved either in acetate metabolism ...
