Survey of Uterine Cervix Cancer Screening by Examination Car in Niigata Prefecture from 1995 to 2009

Based on the results obtained from 1995 to 2009, we explored the current activity statuses of the uterine cervix cancer screening by examination car conducted in Niigata Prefecture. A total of 318,580 women between age 20 and 85 (60,215 initial examinees including examinees who received cancer screening at interval of more than 3 or 5 years, and 258,365 re-examinees who received the screening more than twice within the past 3 or 5 years) were screened during this 15-year period. The mean consultation rate (proportion of examinees to the target population) was 4.10%, showing the highest rate 5.50% in 1996 and the lowest rate 1.98% in 2007. By the cancer screening, 255 cancer patients were detected in the 15 years (mean detection rate: 0.08%, range: 0.04% -1.30%). The mean cancer detection rate in the initial examinees (0.28%, 167 cases) was 8.1 times higher than that in the re-examinees (0.03%, 88 cases). Furthermore, the frequency of examinees diagnosed with dysplasia in the initial examinees was 5.7 times higher than that in the re-examinees (0.51% vs. 0.09%). Examinees requiring detailed examination (3.27%), or examinees diagnosed with dysplasia (0.18%), were detected at the highest rate in their twenties. However, the overall cancer detection rate in their twenties (0.17%) was the secondhighest during the study period, after that in their thirties (0.24%). The cancer detection rate leveled off at about 0.08% during the 15 years, and higher detection rates were found in the initial examinees, especially in their twenties and thirties. We believe the increase in cancer screening examinees of these generations is related to the increase in detection rates of dysplasia or cancer, and may be implicated in the future decrease in the cervical cancer death rate

In-Plane Anisotropy and Temperature Dependence of Oxygen Phonon Modes in YBa₂Cu₃O₆.₉₅

Inelastic pulsed neutron scattering measurements on YBa2Cu3O6.95 single crystals indicate that the sample has a distinct a-b plane anisotropy in the oxygen vibrations. The Cu-O bond-stretching-type phonons, which are suspected to interact strongly with charge, are simultaneously observed along the a and b directions due to a 7-meV splitting arising from the orthorhombicity, even though the sample is twinned. The bond-stretching LO branch with the polarization along a (perpendicular to the chain) loses intensity beyond the middle of the zone, indicating branch splitting as seen in doped nickelates, with the second branch being located at 10 meV below. The mode along b has a continuous dispersion. These modes show temperature dependence, which parallels that of superconductive order parameter, suggesting significant involvement of phonons in the superconductivity of this compound
