Goal: The aim of the current studies was to evaluate the ability of individual defenses to differentiate Antisocial (APD) and Borderline (BPD) personalities. Because multiple defense measures were utilized, Study 1 was dedicated to evaluating the convergent validity between the measures used: Defense Style Questionnaire (DSQ), Defense-Q, and Defense Mechanism Manual (DMM). Studies 2, 3, and 4, then evaluated the ability of the defenses to differentiate APD and BPD groups. Method: In Study 1, participants completed all defense measures and correlations were conducted between the individual defenses. In Studies 2, 3, and 4, groups of nonclinical participants were divided into APD and BPD groups based on scores from the Personality Assessment Inventory. They also completed the DSQ (Studies 2, 3, & 4), the Defense-Q (Study 3), and/or the DMM (Study 4).The groups were then examined for differences on defenses using MANOVA and DFA analyses. Results: Results from Study 1 revealed no significant correlations between the measures for any of the individual defenses. In Studies 2, 3, and 4, DSQ and Defense-Q results revealed that defenses were able to differentiate the APD and BPD groups, but the DMM results did not replicate these findings. Univariate analyses showed that many defenses differed between the groups (e.g., Acting Out, Denial, and Turning Against Self), while others showed no differences (e.g., Idealization). Conclusion: The results were discussed in relation to previous theory and research. The findings provided support for many theoretical expectations. For example, the results supported: Kernberg (1984) who posited both groups would use primitive defenses (e.g., Splitting, Denial); Perry and Cooper (1986) who posited BPD groups would internalize negative views towards the self; and Gacono and Meloy (1988) who believed Denial was characteristic of APD. Overall, the results suggested that APD and BPD groups demonstrated differences in defense use.

A 12-kDa ribonuclease was purified from Pleurotus sajor-caju . The ribonuclease inhibited fungi growth and two species of bacteria, Pseudomonas aeruginosa and Staphylococcus aureus. It reduced the viability of hepatoma and leukemia cells and inhibited translation in a cell-free rabbit reticulocyte lysate system. / A 13-kDa lectin was isolated from Collybia veultipes. Its N-terminal sequence shows some similarity to other fungal immunomodulatory proteins. It stimulated [3H-methyl] thymidine uptake by mouse splenocytes and inhibited proliferation of leukemia cells. / A 14.4-kDa antifungal protein was purified from Agrocybe cylindracea . It exerted antifungal activity but lacked inhibitory activity against bacteria when tested up to 300 muM. It attenuated the activity of HIV-1 reverse transcriptase. / A 17-kDa hemolysin was purified from Pleurotus eryngii. It exhibited cytotoxicity toward leukemia cells but not toward fungi. It exhibited antibacterial activity against Bacillus species. / A 27.5-kDa antifungal protein, with an N-terminal sequence similar to heat shock protein and endoglucanase, was purified from Lentinula edodes. It inhibited fungal growth and exerted an inhibitory activity on HIV-1 reverse transcriptase and proliferation of leukemia cells. / A 7-kDa ubiquitin-like protein was purified from Agrocybe cylindracea . It showed antiproliferative activity on leukemia and hepatoma cell lines, and enhanced nitric oxide production in murine peritoneal macrophages. / An 18-kDa lectin, with an N-terminal sequence similar to some lectins and fungal immunomodulatory proteins, was isolated from Ganoderma capense. It exhibited potent mitogenic activity toward mouse splenocytes, and antiproliferative activity toward leukemia and hepatoma cells. / Mushrooms produce a variety of proteins with interesting biological activities. They include lectins, antifungal proteins, ribonucleases, ubiquitin-like proteins, hemolysins and other peptides. / This study demonstrates that different types of defense proteins with diverse biological activities are produced by mushrooms. Some overlap is observed in the spectra of biological activities of the same type of defense proteins. The results of protein characterization provide crucial information for future genetic manipulation in agricultural and food industries. Studies of the in vitro action of the abovementioned defense proteins on fungi, bacteria, viral enzyme, immune cells and cancer cells indicate that the proteins are potentially exploitable drug agents. / Ngai Hung-kui. / "July 2005." / Adviser: Ng Tzi Bun. / Source: Dissertation Abstracts International, Volume: 67-01, Section: B, page: 0012. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2005. / Includes bibliographical references (p. 228-294). / Electronic reproduction.

Defence against predators is fundamental to increasing an organism's fitness. My thesis explores this central theme in behavioural ecology using stingless bees as study organisms. The thesis contains a general introduction (Chapter 1), three data chapters (2-4) and a final discussion (5). Chapter 2 is a comparative study of aggression in nest defence among stingless bee species, and describes a new form of nest defence, suicidal biting, which is most prevalent in the genus Trigona. Chapter 3 describes a remarkable behaviour in Partamona helleri, which crashes head-first when entering its nest. An experiment suggests that this behaviour helps to avoid predation at the nest entrance. Chapter 4 studies nest defence in the hovering guards of Tetragonisca angustula, and demonstrates that through coordinated vigilance, a group level behaviour rarely observed in animals, the ability of the group to detect predators is enhanced.
