biological control of some plant diseases caused by rhizoctonia solani has been considered as an alternative to chemicals control. rhizobacterium burkholderia cepacia is of current interest as a successful biocontrol agent, and registered as a microbial pesticide by us environmental protection agency. several research works have suggested that nitrogen fixing is also a common feature of most st...

PURPOSE One of the most prominent changes that occurs in the retinal pigment epithelium during senescence is the progressive accumulation of the autofluorescent pigment lipofuscin. Experiments were conducted to evaluate the role of nonenzymatic oxidation of photoreceptor outer segments in retinal pigment epithelium lipofuscin formation. METHODS Albino Fischer rats were given intravitreal inje...

Duerre, John A. (University of North Dakota, Grand Forks), and Patrick J. Buckley. Pigment production from tryptophan by an Achromobacter species. J. Bacteriol. 90:1686-1691. 1965.-A microorganism was isolated from the soil near the University of North Dakota. Biochemical and morphological characteristics indicated that this organism would best be classified as a member of the family Achromobac...

The experiment recorded in this note was undertaken in 1917, with a view to testing the notion (Crozier, 1914-15) that the fluorescent, greenish yellow, integumentary pigment characteristic of some members of the genus ttolothuria is concerned with their photic sensitivity. A functional connection of this sort was suspected because the presence and relative amount of the pigment seemed to be co...

C-phycocyanin, a natural blue-colored pigment-protein complex was explored as a novel photosensitizer for use in low-level laser therapy under 625-nm laser illumination. C-phycocyanin produced singlet oxygen radicals and the level of reactive oxygen species (ROS) were raised in extended time of treatment. It did not exhibit any visible toxic effect in the absence of light. Under 625-nm laser ir...
