The Cystoscope — Its Diagnostic Value

The Electric Cystoscope

Deep-level diagnostic value of the rDNA-ITS region.

The similarity of certain reported angiosperm rDNA internal transcribed spacer (ITS) region sequences to those of green algae prompted our analysis of the deep-level phylogenetic signal in the highly conserved but short 5.8S and hypervariable ITS2 sequences. We found that 5.8S sequences yield phylogenetic trees similar to but less well supported than those generated by a ca. 10-fold longer alig...

Diagnostic utility of Stenger test: reappraisal of its value.

OBJECTIVE Nonorganic hearing loss (NOHL) is a lack of consistency in audiological testing. Although NOHL is relatively rare, it is important to identify suspicious patients. This study was designed to evaluate the effectiveness of Stenger test and acoustic reflexes test (ART) in the evaluation of patients with suspicious of unilateral NOHL. STUDY DESIGN A prospective study Methods: In this st...

Serum microRNA-451a expression and its diagnostic value in glioma

Background: MicroRNAs (miRNA) have been confirmed to act as important diagnostic or prognostic markers in various cancers. The purpose of this study was to investigate the role of miR-451a in the diagnosis of glioma. Methods: The expression of miR-451a was detected by quantitative real-time polymerase chain reaction (qRT-PCR) analysis. And its relationship with clinicopathologic characteristics...

Nucleolar structure in cancer and its diagnostic value.

A modification of the toluidine blue-molybdate stain to demonstrate the internal structure of the nucleolus is described for use in diagnostic cytology. The method demonstrates roughly spherical ribonucleoprotein structures (nucleolini) which are characteristically all the same size in non-neoplastic cells ( isonucleolinosis) but which vary strikingly in neoplastic cells, (anisonucleolinosis). ...
