Dissertations

Problem. Few attempts have been conducted to assess knowledge of HIV/AIDS in the adolescent population attending Seventh-day Adventist secondary schools. This present study was to investigate the HIV/AIDS-related beliefs, HIV/AIDS-related knowledge, and HIV/AIDS-related behaviors of adolescents according to gender, grade level, ethnicity, geographical location, and religious affiliation.

Method. The subjects for this study were 1,292 9th- through 12th-grade students attending selected non-boarding Seventh-day Adventist academies representing three geographical regions of the United States and the Virgin Islands. The survey instrument utilized was the "AIDS Survey for Students" obtained from the U.S. Center for Disease Control. Chi-square analysis was used to …

Cortical Type 2 Astrocytes Are Not Dye Coupled Nor Do They Express The Major Gap Junction Genes Found In The Central Nervous System, Daniel Belliveau, C. Naus

Daniel J. Belliveau

The O‐2A progenitor cell first described from the rat optic nerve is a bipotential precursor of oligodendrocytes and type 2 astrocytes. Each cell expresses specific markers that distinguish them as unique cell types. O‐2A progenitors cultured in high serum preferentially differntiate into type 2 astrocytes and when exposed to defined medium or low serum develop along the oligodendrocyte lineage. We analyzed the gap junction gene expression of type 2 astrocytes to determine if they are coupled to form a syncytium, like their type 1 astrocyte counterparts. Dye coupling experiments demonstrated that cortical type 2 astrocytes are not coupled, while type …
