Methods : The subject group consisted of 534 patients, and all of whom were diagnosed as ASC-US according to a Papanicolaou smear, and they all underwent concomitant HPV DNA microchip test. Results : The occurrence rates of overall squamous lesions and high risk lesion (cervical intraepithelial neoplasia grade 2 and grade 3, and invasive carcinoma) of the HPV-positive ASC-US patients were significantly higher than those of the HPV-negative
ASC-US patients. High risk lesion was detected more frequently among the older patients www.selleckchem.com/screening/kinase-inhibitor-library.html and the patients with HPV 56, 33 or 70. On the follow-up HPV DNA microchip test, only 1 of 11 (9.1%) HPV type-switched women developed squamous lesion compared with 8 of 13 (61.6%) HPV type-persistent women who
developed squamous lesion. Conclusions : The HPV DNA FK228 solubility dmso microchip test is useful for the management of ASC-US patients. HPV-positive ASC-US patients should undergo a HPV DNA microchip test periodically. If the same genotype of HPV is persistent on the follow-up test, more increased surveillance is needed.”
“Objective-To evaluate effects of high incubation temperatures on results of protozoal culture and real-time PCR testing for Tritrichomonas foetus inoculated n a commercially available self-contained culture media system.
Design-In vitro experimental study.
Sample-2 strains of T foetus (1 field isolate from the University of California-Davis and 1 field isolate from the Texas Veterinary Medical Dibutyryl-cAMP mw Diagnostic Laboratory).
Procedures-2 sets of 36 dual-chamber media pouches were inoculated with T foetus (36 sample pouches/strain) and incubated at temperatures of 37.0 degrees C (98.6 degrees F), 46.1 degrees C (115.0 degrees F), or 54.4 degrees C (130.0 degrees F) for 1, 3, 6, or 24 hours. Six uninoculated media samples in pouches stored at 37.0 degrees C for the entire treatment period were used as negative controls. Pouches were removed from incubators and stored at 22.2 degrees C (72.0 degrees F) until all treatments ware complete.
Samples were submitted to a diagnostic laboratory for protozoal culture and real-time PCR testing.
Results-T foetus was detectable microscopically in inoculated pouches incubated at 37.0 degrees C regardless of exposure time, whereas those incubated at 46.1 degrees C yielded T foetus after 1 and 3 hours only, and those incubated at 54.4 degrees C yielded T foetus after 1 hour only. Testing via real-time PCR assay yielded positive results for all inoculated media samples and negative results for all uninoculated control samples.
Conclusions and Clinical Relevance Samples collected into the self-contained culture media system for T foetus testing via culture alone should be protected from high temperatures.
