From the inside to the outs: possible selves and transition planning for youth in custody.Creedon, Kate 23 August 2011 (has links)
Transitions during adolescence can be difficult, but for youth in custody, transitions present a unique set of challenges (Collins, 2001), particularly when moving out of custody and into the community. Considerable research has been done on youth in custody, but few researchers have asked youth for their own thoughts about their future and return to the community. This qualitative study was conducted to explore the possible selves of seven youth in the Victoria Youth Custody Centre in Victoria, BC. Elicited through the Possible Selves Mapping Process (Marshall & Guenette, 2011) and semi-structured interviews, the youth described a number of hoped-for selves, including getting out of the system, not returning to jail, concern for their families, and educational and work aspirations. Feared selves included returning to custody, not being successful in life, and returning to their criminal ways. Participants also identified supports and barriers related to their release. Supports included professionals, programs, and establishing healthy relationships in their lives. Perceived barriers included drugs and alcohol, poor peer relations, and repercussions of their criminal lifestyle. The results have important implications for research, practice and policy regarding youth in custody. / Graduate

Novel Polysaccharide Based Polymers and Nanoparticles for Controlled Drug Delivery and Biomedical ImagingShalviri, Alireza 07 January 2013 (has links)
The use of polysaccharides as building blocks in the development of drugs and contrast agents delivery systems is rapidly growing. This can be attributed to the outstanding virtues of polysaccharides such as biocompatibility, biodegradability, upgradability, multiple reacting groups and low cost. The focus of this thesis was to develop and characterize novel starch based hydrogels and nanoparticles for delivery of drugs and imaging agents. To this end, two different systems were developed. The first system includes polymer and nanoparticles prepared by graft polymerization of polymethacrylic acid and polysorbate 80 onto starch. This starch based platform nanotechnology was developed using the design principles based on the pathophysiology of breast cancer, with applications in both medical imaging and breast cancer chemotherapy. The nanoparticles exhibited a high degree of doxorubicin loading as well as sustained pH dependent release of the drug. The drug loaded nanoparticles were significantly more effective against multidrug resistant human breast cancer cells compared to free doxorubicin. Systemic administration of the starch based nanoparticles co-loaded with doxorubicin and a near infrared fluorescent probe allowed for non-invasive real time monitoring of the nanoparticles biodistribution, tumor accumulation, and clearance. Systemic administration of the clinically relevant doses of the drug loaded particles to a mouse model of breast cancer significantly enhanced therapeutic efficacy while minimizing side effects compared to free doxorubicin. A novel, starch based magnetic resonance imaging (MRI) contrast agent with good in vitro and in vivo tolerability was formulated which exhibited superior signal enhancement in tumor and vasculature. The second system is a co-polymeric hydrogel of starch and xanthan gum with adjustable swelling and permeation properties. The hydrogels exhibited excellent film forming capability, and appeared to be particularly useful in controlled delivery applications of larger molecular size compounds. The starch based hydrogels, polymers and nanoparticles developed in this work have shown great potentials for controlled drug delivery and biomedical imaging applications.

Characterisation of Escherichia coli GTPase Der reveals previously unknown regulation by RNAAung-Htut, May Thandar, Biotechnology & Biomolecular Sciences, Faculty of Science, UNSW January 2008 (has links)
GTPases are found in all domains of life and are highly conserved. In eukaryotes, they serve as signalling molecules for many cellular processes. However, the prokaryotic GTPases play a very different role and are found to be associated with ribosome function. Among the 11 conserved GTPases, Der is the most interesting in prokaryotes. It possesses a unique structure with two GTPase domains (G-Domains) tethered by a variable length acidic linker and a carboxyl terminal KH-like domain. The exact function of Der is still under investigation and most of the data suggest that it is important for 50S ribosomal assembly or stability. In order to investigate the function of Escherichia coli Der (Ec-Der), expression plasmids for wild-type and mutated proteins were created and the proteins were successfully expressed. The expression of the mutant protein that lacked G-Domain 1 was toxic to the cells and it was found that some large ribosomal proteins were missing from the ribosomes of these cells. In addition, other macromolecular complexes such as the GroEL/GroES chaperonin appeared not to be assembled under these conditions. The activities of both wild-type and mutated proteins were also tested and found to be dependent on potassium ions (K+), which enhanced nucleotide binding. Additionally, intra-molecular control over nucleotide binding and release was also observed for Ec-Der. The in vitro selection of RNA aptamers with nanomolar affinity for Ec-Der produced aptamers that contained short variable sequences. These aptamers affected the growth of the E. coli cells and caused a change in cellular morphology that had been noted previously during Ec-Der over-expression. Ec-Der showed high affinity (nM) to both selected RNA and the unselected RNA library. The activity of Ec-Der and Era was inhibited in the presence of any sequence of RNA that has the length of greater than 16 nucleotides. RNA was also cross-linked to Ec-Der in the presence of GTP, but not GDP, suggesting that RNA was a regulator of the Ec-Der GTPase cycle. Based on these results, it is speculated that Ec-Der might be involved in more than one function. It may be acting at the level of the membrane (based on cellular morphology reported here and by Hwang and Inouye 2001) and may also take part in processes related to ribosome function. Regulation of protein activity by RNA length has not been predicted or described and this may represent a novel mean of regulation of the Era subfamily of GTPases.
