Is [ Acanthocyturia more efficient in to differentiate glomerular from non-glomerular hematuria then dysmorphic erythrocytes ]?
Phase-contrast microscopy urinary sediment acanthocyte count is more effective than dysmorphic red cell count in the diagnosis of glomerular hematuria.
At 3 months of age, both the ER alpha(+/NERKI) and ER alpha(-/NERKI) mice had deficits in cortical, but not in trabecular, bone. Remarkably, changes in cortical bone after ovariectomy and estrogen replacement in ER alpha(-/NERKI) mice were the opposite of those in ER alpha(+/+) mice. Relative to sham mice, ovariectomized ER alpha(-/NERKI) mice gained more bone (not less, as in ER alpha(+/+) mice), and estrogen suppressed this increase (whereas augmenting it in ER alpha(+/+) mice). Estrogen also had opposite effects on bone formation and resorption parameters on endocortical surfaces in ER alpha(-/NERKI) versus ER alpha(+/+) mice. Collectively, these data show that alteration of the balance between classical and nonclassical ER alpha signaling pathways leads to deficits in cortical bone and also represent the first demonstration, in any tissue, that complete loss of classical ERE signaling can lead to paradoxical responses to estrogen. Our findings strongly support the hypothesis that there exists a balance between classical and nonclassical ER alpha signaling pathways, which, when altered, can result in a markedly aberrant response to estrogen.
