Cytolytic T cells use two mechanisms to kill virally infected cells, tumor cells, or other potentially autoreactive T cells in short-term in vitro assays. The perforin/granule exocytosis mechanism uses preformed cytolytic granules that are delivered to the target cell to induce apoptosis and eventual lysis. FasL/Fas (CD95 ligand/CD95)–mediated cytolysis requires de novo protein synthesis of FasL by the CTL and the presence of the death receptor Fas on the target cell to induce apoptosis. Using a CD8+ CTL clone that kills via both the perforin/granule exocytosis and FasL/Fas mechanisms, and a clone that kills via the FasL/Fas mechanism only, …

The Effect Of Tape And Neoprene Ankle Supports On Balance In Athletes With Injured Ankles, Tara Michelle Gerlach
Theses, Dissertations and Capstones
Injuries to the ankle joint are among the most common in athletics (Feuerbach et al., 1994; Gross, 1987). As clinicians, it is important to investigate various factors which could potentially reduce the occurrence of ankle injuries. One such actors is an improvement in proprioception (Cox et al., 1993; Glencross & Thornton, 1994). A suggested method for improving proprioception in the ankle is application of an external support, such as tape or a brace (Feuerbach et al. , 1994; Karlsson & Andreasson, 1992 ) . This study compared the proprioceptive abilities of the ankle under three conditions: unsupported, taped, and using …

Sporulation is a developmental process in which temporally distinct sets of genes regulate the processes of meiosis and ascospore formation. Sporulation-specific genes are classified into early, middle, and late genes based on their peak time of expression during sporulation. Regulation of two late genes, SPR1 and SPR2, was studied. The function of SPR2 is unknown. Its regulatory region contains two Mid Sporulation Elements (MSE) repeated in tandem that are sufficient to confer sporulation-specific regulation to a CYCl-lacZ reporter. These sequences have UAS (upstream activation sequence) properties, as each 14 base pair element is sufficient to confer sporulation-specific regulation …
