The personality characteristics of three different groups of athletes at the University of British Columbia were investigated to determine: 1. If significant differences existed among the personalities of the three different groups. 2. If there were significant differences in personality between the total number of athletes tested and the college norms. 3. If one group of athletes differed from the norm more than the other groups. Cattell's Sixteen Personality Factor Questionnaire was administered to forty-five subjects competing in intercollegiate athletics at the University of British Columbia. Fifteen of the subjects participated in basketball, fifteen in football, and fifteen in hockey. Results derived by the method of an analysis of variance and “t" tests indicated that: 1. The hockey group scored significantly higher than the football group on the personality factor, radicalism. 2. The total number of athletes tested scored significantly lower on the factors, shrewdness and apprehensiveness, and significantly higher on the factor, Intelligence, in comparison with established college norms. 3. The hockey group scored higher than the college norms on three personality factors, namely, intelligence, tough-mindedness and radicalism. / Education, Faculty of / Curriculum and Pedagogy (EDCP), Department of / Graduate

This thesis is based on the use of ISSR method for studying genetic diversity of oilseed rape. Altogether, 180 genotypes were evaluated. Frozen leaves of oilseed rape from three breeding station called: 1/ breeding station Selgen a.s., 2/ OSEVA PRO s.r.o. and 3/ breeding station Slapy u Tábora were used as imput material. DNA isolation was performed by Williams, who modified CTAB method for oilseed rape. We selected for ISSR 4 UBC which showed high variability and stability. The analysis was performed by gel electrophoresis. This thesis is also focused on comparison of gel electrophoresis and chip electrophoresis. In this thesis We show a matrix of simmilarity between varieties. The results were also provided back to breeders as a basis for further breeding.

During the intervals “free‐ofneoplasia”, between the initially diagnosed tumor and its recurrences, there are not undisputable histological alterations in the mucosa, although some studies have reported DNA damage in urothelial cells. In order to understand developmental characteristics of UBC, primary tumors and their recurrences were cytogenetically evaluated for their genomic expression by High Resolution Comparative Genomic Hybridization (HR‐CGH). Tumors and their respective recurrences, six low‐grade (LG) and five high‐grade (HG) cases, provided 20 tissue samples that were submitted to laser microdissection capture followed by HR‐CGH. HR‐CGH profiles had two different analyses – all tumors altogether or classified according to their respective histological grades. Both comparisons showed high frequency (80%) of gains in 11p12 and losses in 16p12, in agreement with the literature that indicate alterations of 11p and 16p in UBC recurrences. These findings suggest that those chromosome regions contain putative oncogenes and tumor suppressor genes critical for urinary bladder carcinogenesis. Within a same patient genomic profile showed high agreement between tumors and their respective recurrences, i.e., tumors from the same patient showed a large number of common losses and gains. The high similarities of genomic alterations in successive tumors from the same patient suggest that a stable genomic profile was established in UBCs and their recurrences. Besides, during the “free‐of‐neoplasia” intervals, negative urinary bladder washes were submitted to Fluorescent in situ Hybridization (FISH) to detect quantitative alterations in centromeres 7 (n=21 samples), 17 (n= 21) and 9p21 (n=36).

Meiosis is a highly regulated process, partly due to the need to break and then repair DNA as part of the meiotic program. In this thesis, mechanisms of meiotic regulation are investigated, including the post-translational modification termed SUMOylation, and a potential novel negative regulator of error-prone DNA repair pathways. Post-translational modifications are widely used during meiotic events to regulate steps such as protein complex formation, checkpoint activation, and protein attenuation. In this thesis, we investigate how proteins that are obligatory components of the SUMO pathway, one such post-translational modification, affect the C. elegans germline. We show that UBC-9, the E2 conjugation enzyme, and the C. elegans homolog of SUMO, SMO-1, localized to germline nuclei throughout prophase I. Mutant analysis of smo-1 and ubc-9 revealed increased recombination intermediates throughout the germline, originating during the mitotic divisions. SUMOylation mutants also showed late meiotic defects including defects in the restructuring of oocyte bivalents and endomitotic oocytes (EMO). Increased rates of non-interfering crossovers (COs) were observed in ubc-9 heterozygotes, even though interfering COs were unaffected. We have also identified a physical interaction between UBC-9 and DNA repair protein MRE-11. ubc-9 and mre-11 null mutants exhibited similar phenotypes at germline mitotic nuclei and were synthetically sick. These phenotypes and genetic interactions were specific to MRE-11 null mutants as opposed to RAD-50 or resection-defective MRE-11. We propose that the SUMOylation pathway acts redundantly with MRE-11, and in this process MRE-11 likely plays a structural role. We also found a candidate negative regulator of non-homologous end joining through an RNAi screen using the mre-11(iow1) resection-defective mutant. Mutant analysis did not rescue the resection-defective phenotype when multiple CRISPR-generated nhr-2 deletion alleles were generated. Therefore, nhr-2 does not appear to be directly involved in DNA repair.
