The phase dynamics strongly depends on the magnetization state of the reference layer, showing that the instability of the reference layer could be responsible for the random fluctuation events. (C) 2011 American Institute of Physics. [doi:10.1063/1.3592973]“
“PURPOSE To perform
white-to-white selleck products (WTW) and angle-to-angle (ATA) distance measurements with 2 optical devices and analyze the correlation with other anterior segment parameters
SETTING Department of Ophthalmology, Medical Health and Science Center, University of Debrecen, Debrecen, Hungary
DESIGN Comparative case series
METHODS In this prospective study, the WTW distance, axial length (AL), and anterior chamber depth (ACD) were measured by partial coherence interferometry (PCI) (IOLMaster) The horizontal and vertical ATA distances and ACD were assessed by anterior segment optical coherence tomography (AS-OCT) (Visante)
RESULTS The mean PCI values were AL, 23 31 mm +/- 1 52 (SD), WTW distance, 11 99
+/- 0 47 mm, ACD, 2 99 +/- 0 4 mm On AS-OCT, the mean horizontal ATA was 11 43 +/- 0 51 mm and the mean vertical ATA, 10 72 +/- 0 66 mm The WTW distance was significantly greater than the horizontal ATA distance and the horizontal ATA distance was significantly greater than the vertical ATA distance (P< 0001) The correlations between WTW and horizontal ATA (r = 0 51, P< 0001) vertical ATA (r = 0 32, P< 0021) AL (r = 0 45, P< 0001) and patient age (r = 0 28 P = 023) were significant The PCI WTW distance and ACD were significantly correlated (r = 0 55, P< 0001) There were no significant correlations between AS-OCT Selleck Mocetinostat horizontal and vertical ATA measurements (r = -0 02, P = 0 79) or between same-device
ACD measurements (r = 0 18, P = 15)
CONCLUSIONS Although PCI WTW and AS-OCT ATA measurements are not clinically interchangeable, the WTW values correlated well with horizontal and vertical measurements and other anterior segment parameters”
“Early detection of adefovir dipivoxil-resistant mutants during long-term treatment of chronic hepatitis B virus (HBV) infection with this drug is of great clinical importance. We developed an improved reverse dot hybridization Acadesine in vitro test for simple and rapid detection of the rtA181V/T and rtN236T mutations associated with adefovir dipivoxil resistance in chronic hepatitis B patients. Probes were designed for genotypes B, C, and D of this resistance characteristic; a total of 70 clinical samples were analyzed with this improved reverse dot hybridization assay. Its usefulness was validated by comparing with sequencing data. Discordant results were confirmed by subclone sequencing. This reverse dot hybridization assay was sufficiently sensitive to detect 10(3) copies/mL; it also detected adefovir dipivoxil-resistant mutant strains when they comprised more than 5% of a mixed virus population. This reverse dot hybridization array correctly identified adefovir dipivoxil-resistant mutants; it had high concordance (98.
