If a NH resident is negative after a single PPD skin test on admission and is then positive when next tested 6 or 12 months later, the conversion may be due either to the booster phenomenon or to the intercurrent development of primary infection. This potential ambiguity will be minimized by...
Expression vectors were generated in the pSMdelta vector backbone (a derivative of pPD49.26).TransgenicC. eleganswere prepared by microinjection into the gonad [47] usingPmyo2 > mCherry(2 ng/ µl) as a co-injection marker. C. elegans strains used in this study are listed in Table1...

Of 619 enrollees completing the protocol, 174 (28%) had a positive PPD and 24 of the remaining 445 (5%) had a positive booster test. On multivariate analysis, boosting was associated with older age (adjusted odds ratio [ORadj] 2.38/decade, 95% confidence interval [CI] 1.34-4.22), ...
Five (17.2%) of the patients with positive PPD and two of the patients (2.1%) with negative PPD results subsequently developed active TB within 12 months. Conclusion. We found a significant booster effect in our hemodialysis patients using TST-2. Repeat PPD test with the same dosage could ...

Design/Methodology: We maintained a log of all recently employed staff that had a positive PPD between April 30, 2008 and October 7, 2009. Each of our newly employed staff who had a positive PPD also had a QuantiFERON blood test to validate their positive PPDs. Results: During this period...

The size of each PPD was 2.3 × 2.3 μm2. Because the AM was implemented with an MIM capacitor using the BSI CIS process, the AM on the front side did not degrade the sensitivity. In the proposed two-step comparison scheme, the AM must be accessed 128 times using a column amplifier....
