BACKGROUND: Pathologic lymph node staging is becoming a deficient method in the demanding molecular era. Nevertheless, the use of more sensitive molecular analysis for nodal staging is hampered by its high costs and extensive time requirements. Our aim is to take a step forward in colon cancer (CC) lymph node (LN) pathology diagnosis by proposing a feasible and efficient molecular method in routine practice using reverse transcription loop-mediated isothermal amplification (RT-LAMP). RESULTS: Molecular detection of tumor cytokeratin 19 (CK19) mRNA with RT-LAMP was performed in 3206 LNs from 188 CC patients using two methods: individual analysis of 1449 LNs from 102 patients (individual cohort), and pooled LN analysis of 1757 LNs from 86 patients (pooling cohort)...

PURPOSE: We sought to determine what role SHBG played with male infertility patients. METHODS: Retrospective review of 168 males seen in a fertility clinic from 2012-2014, to investigate the accuracy of TT in the biochemical diagnosis of hypogonadism using cBT as the reference value. We used a multivariable analysis to assess SHBG as an independent predictor of infertility. RESULTS: Computations using cBT as a standard in the measurement of definitive biochemical hypogonadism (<156 ng/dL) revealed a sensitivity, specificity, PPV, and NPV respectively of 81%, 83%, 81%, and 82% in diagnosing hypogonadism with TT alone...

Poly(p-phenylene vinylene) (PPV) nanoparticles in aqueous colloidal solution have been prepared via a modified Wessling method, with the addition of surfactant. The fluorescent colloidal solution was used as the developing solution to develop the fingerprints on different substrates. The developing process was accomplished simply by immersing the substrates into developing solution and then taking out, followed by rinsing with deionized water. The initial study about the fingerprints on the adhesive tapes showed that the developing solution is very effective in fluorescence developing on both fresh and aged visible fingerprints; and such effect was negligibly affected by treating the fingerprints with water or other organic solvents, whether before developing or after...
