Application of comparative genomic hybridization technique for detection of chromosomal aberrations in benign cystic teratoma.

Benign cystic teratoma, also known as dermoid cyst, is the most common of all ovarian neoplasms accounting for 10%-20% of all ovarian cysts. Most have a normal 46,XX karyotype. Less than 2% can undergo malignant transformation. By using the comparative genomic hybridization technique on nine benign ovarian cysts we were able to show two cases with chromosomal aberrations not seen before in dermoid cysts but known to be involved in malignant ovarian tumors. We speculate that these are the tumors carrying the potential for malignant transformation.

Spectral Radiative Flux Divergence and Its Variability in the Troposphere in the 0.4-2.4-micro Region.

Within the program of the Complex Atmospheric Energetics Experiment (CAENEX-70) and with the help of an IL-18 aircraft flying laboratory, we have measured spectral (in the 0.4-2.4-microm interval) radiative fluxes, the energy balance, and flux divergence of energy in a free atmosphere (at 0.3-8.4-km heights) with Z = 55 degrees over a sandy surface. Simultaneously, the results of aerosol measurements gave the physical explanation to many peculiar features of optical observations. In particular, aerosol absorption of shortwave radiation has been isolated. The probable variability of aerosol absorption has been estimated on the basis of observational data obtained on other days.
