Two genetic elements regulate murine beta-glucuronidase synthesis following transcript accumulation.
Mutant alleles of two genetic regulatory elements, which underlie a three- to sixfold reduction in beta-glucuronidase (GUS) activity levels, distinguish mice of the H haplotype from those of the other two common GUS haplotypes, A and B. Both elements are tightly linked to the GUS structural gene over which they exert control. One (Gus-u) exerts a cis-active effect upon GUS activity levels in al...

lenged with PDE developed extensive interstitial infiltrations of macrophages and multinucleated giant cells that were most prominent around respiratory bronchioles but also extended into the alveolar septa. There were also associated perivascular lymphocytic and plasma cell infiltrates. Neither immunization nor aerosol challenge per se resulted in pulmonary inflammation. In contrast, C57BL/10 ...
متن کاملAndrogen Regulation of Murine P-Glucuronidase Expression: Identification and Characterization
One of the major features of P-glucuronidase (GUS) expression in inbred strains of the house mouse, Mus musculus, is the responsiveness of this enzyme to androgen stimulation in tubule cells of the kidney. Both GUS-specific and nonspecific mutations have been described which define genes that serve to control this response. During examination of the expression of GUS in the interbreeding subspe...

Synthesis, structure and magnetic properties ofβ-MnO2nanorods
We present synthesis, structure and magnetic properties of structurally well-ordered single-crystalline b-MnO2 nanorods of 50–100 nm diameter and several lm length. Thorough structural characterization shows that the basic b-MnO2 material is covered by a thin surface layer (~2.5 nm) of a-Mn2O3 phase with a reduced Mn valence that adds its own magnetic signal to the total magnetization of the b-...
