The adsorption of polyaromatic hydrocarbons on natural and chemically modified asbestos fibers.

Many reports indicate that the carcinogenic (genotoxic) potential of benzo[a]pyrene (B[a]P) may be enhanced several-fold by the promoter (epigenetic) effect of asbestos particles. This promoting effect could be related to the fact that when B[a]P is adsorbed onto the particles, there is a resulting enhanced transport and uptake of the carcinogen into microsomial membranes. These in vitro data bear relevance to the epidemiological studies which indicate an association between exposure to inhaled asbestos dusts and the high incidence of pulmonary cancers in smokers. Using HPLC, it has been observed that B[a]P has great affinity for natural asbestos fibers, and that chemical modification of natural chrysotile with POCl3 results in the complete loss of this adsorption potential of chrysotile for benzo[a]pyrene.

Characterization of a human Y chromosome Pvu II repeated sequence.

The human Y chromosome carries numerous copies of a tandemly repeated Pvu II sequence, 2.4 kb long. These sequences are specific to humans, and are present in a much smaller amount in the DNA of females. They are localized on the long arm of the Y chromosome. We have compared this sequence with the Hae III 2.1 kb Y-specific repeated sequence, already described.

Alveolar soft-part sarcoma of the orbit.

Alveolar soft-part sarcoma is a malignant soft tissue neoplasm that involves mainly the deep soft tissues of the extremities, particularly the thighs and the buttock. Involvement of the orbit is uncommon. We describe a young child with such a tumor and illustrate the characteristic features.

Nurse educator performance standards.

In this article, the authors highlight the process by which one staff education department developed performance standards. These standards facilitate orientation of new educators, assist with the planning of developmental goals, and guide the evaluation process. This process can serve as a prototype for nurse educators faced with the challenge of developing performance standards.
