A labile inorganic free radical, nitric oxide (.NO), is produced by nitric oxide synthase from the substrate L-arginine in various cells and tissues. It acts as an endothelium-derived relaxing factor (EDRF) or as a neurotransmitter in vivo. We investigated the reactivity of stable radical compounds, imidazolineoxyl N-oxides such as(More)
In the pathogenic yeast Candida glabrata, gene targeting to generate knockouts and "knockins" is a potentially powerful method for the analysis of gene function. Its importance increased after the C. glabrata genome sequence project, but progress in the field is hampered by inefficient mechanisms for gene targeting. With the use of 40-bp homologous flanking(More)
The ubiquitin E3 protein ligase Nedd4-2 is a physiological regulator of the epithelial sodium channel ENaC, which is essential for transepithelial Na+ transport and is linked to Liddle's syndrome, an autosomal dominant disorder of human salt-sensitive hypertension. Nedd4-2 function is negatively regulated by phosphorylation via a serum- and(More)
The intestinal resident Candida glabrata opportunistically infects humans. However few genetic factors for adaptation in the intestine are identified in this fungus. Here we describe the C. glabrata CYB2 gene encoding lactate dehydrogenase as an adaptation factor for survival in the intestine. CYB2 was identified as a virulence factor by a silkworm(More)
The effects of retinal deafferentation on a calcium-binding protein, calretinin, in the upper layers (superficial gray layer and optic nerve layer) of the rat superior colliculus were examined. In intact rats and on the ipsilateral side of unilaterally eye-enucleated rats, the superficial gray layer and optic nerve layer contained a few dispersed(More)
We modified a single argon/dye laser photocoagulator by adding two optical fibers so that it could be used with a slit-lamp microscope, an operating microscope, and with an endophotocoagulation probe. One fiber is attached to a nearby slit-lamp microscope; the other extends approximately 70 m and can be connected to either an operating microscope or an(More)
