A total of 108 male partners of women with cervical condyloma and/or dysplasia underwent evaluation for gross and subclinical condyloma via acetic acid screening with a magnified examination. ...Biopsies of acetowhite genital skin were obtained for histological and deoxyribonucleic acid hybridization analysis. Of the men 52 (49%) had acetowhite lesions and underwent biopsies, 44 of which were evaluable by histological and deoxyribonucleic acid analyses. Of the lesions 12 had features of condyloma or penile intra-epithelial neoplasia, among which 7 (58%) contained human papillomavirus deoxyribonucleic acid. The remaining 32 lesions revealed minimal histological changes sometimes suggesting condyloma. However, only 5 of the 32 biopsies (16%) contained human papillomavirus deoxyribonucleic acid. A tendency to overdiagnose condyloma based on histological findings is suggested. Criteria by which to identify best human papillomavirus-related morphology are presented. Acetowhite genital epithelia with minor (nonspecific) histological changes correlate poorly with human papillomavirus nucleic acids and in most cases do not represent disease involving common viral types. The application of appropriate histological criteria appears to be particularly relevant to management strategies that avoid overtreatment of minor epithelial abnormalities. It remains unclear whether acetowhite genital epithelia positive for human papillomavirus require treatment given the high tendency for recurrence and lack of demonstrated effect on the natural history of cervical carcinoma.
We report on the first multi-color precision light curve of the bright Wolf-Rayet binary \(\gamma^2\) Velorum, obtained over six months with the nanosatellites in the BRITE- Constellation fleet. In ...parallel, we obtained 488 high-resolution optical spectra of the system. In this first report on the datasets, we revise the spectroscopic orbit and report on the bulk properties of the colliding winds. We find a dependence of both the light curve and excess emission properties that scales with the inverse of the binary separation. When analyzing the spectroscopic properties in combination with the photometry, we find that the phase dependence is caused only by excess emission in the lines, and not from a changing continuum. We also detect a narrow, high-velocity absorption component from the He I \(\lambda\)5876 transition, which appears twice in the orbit. We calculate smoothed-particle hydrodynamical simulations of the colliding winds and can accurately associate the absorption from He I to the leading and trailing arms of the wind shock cone passing tangentially through our line of sight. The simulations also explain the general strength and kinematics of the emission excess observed in wind lines such as C III \(\lambda\)5696 of the system. These results represent the first in a series of investigations into the winds and properties of \(\gamma^2\) Velorum through multi-technique and multi-wavelength observational campaigns.

The structure of the title dysprosium coordination polymer, Dy(C9H16O8)n, consists of Dy2O16 dimers linked by adipate bridges to form a two‐dimensional layered structure. Furthermore, intermolecular ...O—H⋯O hydrogen bonds link these layers into a three‐dimensional network.
