To determine the effects of cadmium on the intestinal absorption of calcium, everted gut sacs from rats orally dosed with 0, 0.05, 0.5 or 5.0 mg Cd daily for 3 weeks were placed in media containing 4 x 10/sup -5/ M Ca. Tissue content of calcium after

The lactic dehydrogenase and acetylcholinesterase enzymes of the boll weevil, Anthonomous grandis , have been shown to be inactivated by dye-sensitized photooxidation mediated by substituted xanthenes. The efficiency of the photooxidation reaction wa

Diet containing rose bengal, when fed to newly-emerged adult boll weevils in the absence of light, causes serious biochemical changes in the insect. Body weight, total protein, and certain enzyme levels remain constant in the treated weevils as oppos

Ampholines must be removed from proteins that have been purified using isoelectric focusing chromatography before hydrolysis since ninhydrin positive fragments result. Hollow fiber dialysis was shown to be a fast and efficient method for the removal

1. 1. Acetylcholinesterase contained in whole-head homogenates from the imported fire ant was susceptible to dye-sensitized photooxidation induced by the presence of rose bengal, phloxin B, erythrosin B, eosin yellowish and flourescein. 2. 2. Rhodami

Polyamine levels were evaluated in human HL-60 promyelocytic leukemia cells after treatment with inducers of terminal differentiation. Differentiation in these cells was determined by increases in the percentage of morphologically mature cells and in

Lethal dye-sensitized photooxidation reactions in the black imported fire ant, Solenopsis richteri (Forel), have been defined as a function of whole body concentrations of a series of xanthene dyes. Log probit analysis of mortality data has allowed c

Adult boll weevils, Anthonomous grandis , fed for 4 days from emergence on a dyeimpregnated artificial diet before illumination at 3800 μW/cm2 fluorescent light for 4 h yielded a dietary LD50 value of 9.9×10−4 moles/liter and a tissue LD50 value

1. 1. The dextransucrase from strain 804 of Streptococcus sanguis has been shown to be inhibited by certain xanthene dyes in both a light-dependent (irreversible) and light-independent (reversible) mechanism. 2. 2. The dye binding site overlaps both

The imported fire ant is susceptible to a lethal photooxidation reaction after ingesting rose bengal. The reaction has been shown to be dependent on dye concentration, incubation period prior to exposure, light intensity and exposure time. Imported f
