Elucidating a novel gene associated with myoclonus dystonia
Creators: name: Read, Tara
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Biology, Genetics.

description: Myoclonus Dystonia (MD) is an autosomal dominant disease with high but incomplete penetrance and is characterized by both involuntary myoclonic jerks and dystonic posturing. Our group has found that mutations within the epsilon sarcoglycan (SGCE) gene on chromosome 7q21 are associated with MD in 30-40% of affected individuals in 31 families studied, supporting the basis for genetic heterogeneity. Novel mutations have been found in SGCE by screening these families for point mutations and large deletions and duplications through the use of sequencing, high performance liquid chromatography (HPLC) and multi˙ligation probe amplification (MLPA) analysis. A 10cM genome wide linkage analysis of a large Canadian family provided significant LOD scores for microsatellite markers within the 18p11 region, now designated as the DYT 15 locus. Further haplotype analysis has narrowed a non-recombinant region associated with the disease phenotype to a 3.18 Mb region in this locus. Since the current understanding of Myoclonus Dystonia is poor, it is difficult to predict genes that could be responsible for MD. Sarcoglycans are essential constituents of the dystrophin-glycoprotein complex and are involved in linking the extracellular lamanin matrix to the actin filaments within the cytoplasm; therefore focus is given to the examination of potentially related structural genes that are expressed in the brain. By analyzing such candidate genes in a panel of affected individuals, we believe that a novel gene will be elucidated and provide insight into the mechanism of Myoclonus Dystonia.

Argentina wins brief reprieve from default, but the vulture funds are circling
Creators: name: Esposto, Alexis
Publisher: name: Swinburne

description: Since defaulting on its debt in 2001, Argentina has been locked in a decade-long battle with international investors. Tensions between the country and institutional bondholders reached new highs on October 2, when the Ghanaian government seized the Argentine tall ship ARA Libertad. The ship was prevented from leaving the port of Tema after a Ghanian court upheld a court order at the request of Argentina's creditors, led by US hedge fund Elliot Associates, who are suing Buenos Aires over its 2002 bond default. NML Capital, a firm affiliated with Elliot Associates, is currently trying to recoup $1.3 billion of debt from Argentina through the US legal system in New York. The fund was created by Paul Singer, a strong backer of the US Republican Party and former Republican presidential candidate Mitt Romney. According to The Guardian, Singer's money-making strategy involves 'buying distressed debt cheaply and selling it at a profit or suing for full payment'. Such speculative financial and profitable operations are performed by hedge or financial funds known as 'vulture funds', which obtain their name because they hover like vultures over the remains of moribund companies or debtor states like Liberia, Peru and Argentina. As such, these funds operate in a highly opportunistic and exploitative manner.
hDREF, a MEF2 sensitive regulator of DNA synthesis

description: The Myocyte Enhancing Factor 2 (MEF2) family of proteins have been implicated in a wide variety of cellular mechanisms including: muscle and neuronal differentiation, inhibition of apoptosis, upregulation of c jun expression, and embryonic and post-natal cardiac development. In the course of my research I have identified a novel MEF2-responsive gene referred to as h&barbelow;uman D&barbelow;NA R&barbelow;eplication Related E&barbelow;lement F&barbelow;actor (hDREF). Three putative MEF2 consensus-binding sites have been found within the two untranslated regions (UTRs) of the hDREF sequence (which lie 5' and 3' to the open reading frame). Using CHromatin I&barbelow;mmunolP&barbelow;recipitation (CHIP) assays I have shown that MEF2 proteins associate with the MEF2 binding site found within the 5'UTR of hDREF under both growth and differentiation conditions. Furthermore, mutation of the MEF2 binding sites results in a failure to repress expression, which indicated that MEF2 acts to negatively regulate hDREF expression during differentiation. Endogenous expression studies indicate that hDREF is highly expressed during growth and downregulated during differentiation. Functional studies suggest that hDREF is directly involved in regulating DNA synthesis, and that overexpression of hDREF leads to aberrant DNA replication in post-mitotic cells leading to polyploidy. Based on my research I propose that hDREF represents a novel MEF2 regulated gene, and that the primary function of hDREF is to ensure DNA synthesis with the cell cycle.
Progress towards a new synthesis of lysergic acid

Subjects: subject: Chemistry, Organic.

description: This thesis describes the progress made towards the synthesis of the lysergine ring system 1. Approaches based on benzyne, oxindole, and indole intermediates were explored. Results of these three central strategies are discussed. The benzyne route as outlined in Chapter 2 illustrated the potential to synthesize a key bicyclic intermediate, 3-but-3-enyl-4-iodo-1-methyl-1,3-dihydro-indol-2-one 33. This approach utilized our existing results in benzyne chemistry to construct the lysergine AB ring system. Formation of 33 via a benzyne reaction would be followed by an intramolecular Heck cyclization reaction, resulting in formation of intermediate 34. Due to low yields and difficulty in reproducing 33 in the benzyne reaction, this route was abandoned.* The oxindole route (Chapter 3) was an extension of the ideas developed during the exploration of the benzyne reaction. This approach examined the potential for an intramolecular Friedel Crafts reaction using oxindole-3-propionic acid as the starting material, followed by a Wittig olefination to yield the desired tricyclic intermediate 34. Unfortunately, the Friedel Craft product 70 was highly unstable therefore, this route was also abandoned.* The indole approach described in Chapter 4 combined the original ideas from both the benzyne and oxindole routes. Here, we demonstrated the ease of synthesis in obtaining 2,2-dimethyl-1-(5-methylene-4,5-dihydro-3H-benzo[c,d]indol-1-yl)-propan-1-one 77, the N-pivalyl protected version of intermediate 34. The success in forming 77 enabled us to proceed with the construction of Ring D using a selenium-dioxide allylic oxidation reaction to afford the alpha-alcohol 87. In addition, the alpha,beta-enone isomer 88 was obtained via modified Mannich reaction conditions. The successes realized with the indole approach presented a unique and promising synthetic approach to lysergine 1. *Please refer to dissertation for diagram.
Genetic and physical mapping of the myotonic dystrophy locus on human chromosome 19q13.3.
Creators: name: Shutler, Gary G.
Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Biology, Molecular.

description: The cloning of the myotonic dystrophy (DM) was accomplished in a three part research plan: (1) the characterization of the DNA excision repair cross complementation (ERCC1) gene region by genetic and physical mapping to determine the location of the DM gene relative to this locus, (2) the undertaking of a chromosome walk from the ERCC1 region toward the DM gene to define a minimal area that is to contain the DM locus, and (3) characterization of the essential region containing the DM locus for CpG islands and DM associated abnormalities. Further work done in our laboratory and by others have shown the DM associated allelic expansion to be due to the amplification of a trinucleotide repeat, CTG. This repeat was mapped to the 3$\sp\prime$ untranslated region of a gene which based on sequence homology comparisons encodes a putative serine-threonine protein kinase. This is not unlike the allelic expansion found in fragile X syndrome that is due to an amplification of a CGG trinucleotide repeat mapping to the 5$\sp\prime$ untranslated region of a gene designated FMR-1. The size of the CTG repeats ascertained in 124 normal chromosomes was found to range from 5 to 30 with repeat numbers of 5 and 13 the most common. The repeat numbers in DM chromosomes was found to vary from a minimum of about 50 to over 2000. Only two out of 98 DM families did not show allelic expansion using Southern blot analysis or PCR protocols to ascertain the repeat numbers. These cases either have other mutations at or near this locus or they have another clinically similar disorder mapping elsewhere in the genome. In summary, it is evident from work presented in this thesis that the DM locus has been cloned and that the DM mutation has been identified. (Abstract shortened by UMI.)
Enhancement of the differentiation of preweanling rat hepatocytes in vitro by retinoic acid: A study of bile canaliculi formation.
Creators: name: Claude, Annie.
Publisher: name: Université d'Ottawa / University of Ottawa

description: To study the stimulating effects of retinoic acid on the primary culture of immature rat hepatocyte, we examined the changes in the bile canaliculi formation by observing the cytokeratins 55 kDa and 49 kDa. The formation of the bile canaliculi sheaths was our end point of differentiation. We obtained monolayer hepatocyte culture from 14-day old male Wistar Charles River rats, using the two-step collagenase perfusion method of Seglen (1976), as adapted to preweanling rats by Deschenes et al (1980). All-trans retinoic acid 10$\sp{-5}$M dissolved in 0.1% dimethyl sulfoxide was added to the treated cultures. All cultures were maintained for 48 hours. The organization of cytokeratin was visualized by immunofluorescence using monoclonal antibodies to cytokeratins 55 kDa and 49 kDa. Under the influence of retinoic acid, the number and size of bile canaliculi formed were significantly increased. The bile canaliculi formed and a more complex architecture, such as ramification. Theses observations were confirmed by un-embedded whole mount electron microscopic studies on detergent extracted preparations. In retinoic acid treated colonies, the bile canaliculi appear to be functional as demonstrated by the cellular uptake followed by polarization and secretion of the fluorescein diacetate dye. Gel electrophoresis showed an apparent disparity in the relative quantity of cytokeratin 55 kDa and 49 kDa, especially in the control group. This inequality may be attributed to a selective increase in proteolysis during preparation. It is concluded that the addition of retinoic acid to the media stimulates the differentiation in hepatocyte monolayer cultures. It is possible that retinoic acid induces modification in the hepatocyte gene expression and the formation of bile canaliculi could be associated with changes in the expression of the cytokeratin genes. The two cytokeratins would be coexpressed in response to the treatment with retinoic acid.

description: This paper introduces a preliminary study of synchronisation between packet loss events across concurrent TCP flows. Loss synchronisation is explored over four routing paths – one inside Australia and three international paths (Australia to Asia, Europe and North America respectively). We confirm that loss synchronisation does exist but the level varies from path to path. We outline further work that is required to improve our understanding of loss synchronisation.

description: Macropore flow is a gravity-driven phenomenon that exhibits high contamination risk for surface and shallow groundwater. In order to address the necessity of having reliable and tangible indicators of macropore flow incidence, this research is an extensive data exploration that uncovers potential regional macropore flow incidence indicators that are synthesized as hypotheses for future research. CART-based regression trees are used to uncover significant relationships among soil physical properties, management regimes, field saturated hydraulic conductivity, saturated soil air-entry tensions and earthworm biomass. All of the modeling is based on field-measured data. Prediction scenarios are established in order to develop potential regional indicators of field saturated hydraulic conductivity (Kfs), soil saturated air-entry tension (AEV), and earthworm biomass. The magnitude, range, and pattern of variability of soil water infiltrations are controlled primarily by the well-developed and stable soil structure at the field scale, rather than by texture, organic carbon or surface topography, as classical pedotransfer functions suggest. Tillage is influential for the estimation of all targeted variables. Conventional tillage is associated with rapid shallow infiltration rates and lower air entry tensions both in the cultivation layer and below. Absence of tillage is found to be beneficial for earthworm communities as sampled biomass is greater on no-till field sites. The strong correlations between Kfs and AEV demonstrate good prediction potential but because of their intrinsic spatial and temporal variability, their utility as regional macropore flow indicators is questionable.

The role of brand orientation in the higher education sector: a student-perceived perspective
Creators: name: Casidy, Riza
Publisher: name: Swinburne
Year: 2024

description: The purpose of this paper is to examine the relationship between perceived brand orientation, satisfaction, loyalty, and post-enrolment communication behaviour in the Australian higher education sector. 258 questionnaires were completed by undergraduate students of a particular university in Australia. Structural equation modeling was employed in this study to examine the associations between the constructs. This study provides empirical evidence that perceived brand orientation has a positive and significant relationship with all dependent variables. The research reveals that students’ perception of a university’s brand orientation is significantly related to satisfaction, loyalty, and post-enrolment communication behaviour. The findings may guide the key decision makers in higher education institutions to understand the importance of brand orientation in their corporate strategy to enhance satisfaction, loyalty, and positive WOM, which can be used to differentiate themselves from other institutions in the highly competitive education market. Past researchers have not looked into the dynamic relationships between perceived brand orientation, satisfaction, loyalty, and post-enrolment communication behaviour and hence research is to be called for in this area. The paper is the first to examine brand orientation from the perspective of the students and provide higher education institutions with recommendations to improve service quality through brand orientation.

description: Negative carbon emission technologies are critical for ensuring a future stable climate. However, the gaseous state of CO 2 does render the indefinite storage of this greenhouse gas challenging. Herein, we created a liquid metal electrocatalyst that contains metallic elemental cerium nanoparticles, which facilitates the electrochemical reduction of CO 2 to layered solid carbonaceous species, at a low onset potential of− 310 mV vs CO 2/C. We exploited the formation of a cerium oxide catalyst at the liquid metal/electrolyte interface, which together with cerium nanoparticles, promoted the room temperature reduction of CO 2. Due to the inhibition of van der Waals adhesion at the liquid interface, the electrode was remarkably resistant to deactivation via coking caused by solid carbonaceous species.

description: Background: Currently, there is limited evidence on the effectiveness of second-line antiretroviral therapy (ART) in sub-Saharan Africa. To address this challenge, outcomes of second-line protease inhibitor (PI) based ART in Rwanda were assessed. Methods: A two-stage cluster sampling design was undertaken. 49 of 340 health facilities linked to the open-source electronic medical record (EMR) system of Rwanda were randomly sampled. Data sampling criteria included adult HIV positive patients with documented change from first to second-line ART regimen. Retention in care and treatment failure (viral load above 1000 copies/mL) were evaluated using multivariable Cox proportional hazards and logistic regression models. Results: A total of 1688 patients (60% females) initiated second-line ART PI-based regimen by 31st December 2016 with a median follow-up time of 26 months (IQR 24–36). Overall, 92.5% of patients were retained in care; 83% achieved VL ≤ 1000 copies/ml, 2.8% were lost to care and 2.2% died. Defaulting from care was associated with more recent initiation of ART- PI based regimen, CD4 cell count ≤500 cells/mm³ at initiation of second line ART and viral load > 1000 copies/ml at last measurement. Viral failure was associated with younger age, WHO stage III&IV at ART initiation, CD4 cell count ≤500 cells/mm³ at switch, atazanavir based second-line ART and receiving care at a health center compared to hospital settings. Conclusions: A high proportion of patients on second-line ART are doing relatively well in Rwanda and retained in care with low viral failure rates. However, enhanced understandings of adherence and adherence interventions for less healthy individuals are required. Routine viral load measurement and tracing of loss to follow-up is fundamental in resource limited settings, especially among less healthy patients.

description: Measurements of reflectivity and Hall effect have been made on polycrystalline n-type samples of GaAs and alloys of the systems GaAs xSb1-x and Ga1-xAlxAs to find values of electron effective mass at the bottom of the conduction band m*00/m . The experimental data were obtained with a Baird monochromator which was modified to give double beam operation and extended wavelength range up to 30 mum, so that measurements of the free carrier reflectivity could be made on samples with low carrier concentration. The reflection coefficient R and hence the index of refraction eta were obtained from the experimental measurements. The variation of eta2 was plotted as a function of the square of the wavelength. For each sample, the graphical result (eta 2 vs lambda2) was found to be a straight line and it was extrapolated to zero wavelength to obtain the optical dielectric constant epsilon infinity. The slope of the line also was determined and used to obtain the value of effective mass at the bottom of the conduction band. For the systems GaAsxSb1-x the alloy compositions were determined by the X-ray powder photograph method. For the two alloy systems GaAsxSb1-x and Ga 1-xAlxAs, optical dielectric constant and effective mass values were measured from infrared reflectivity for the first time. The values of the effective masses were determined by the simultaneous solution of the integrals giving the statistical carrier concentration and the slope of the free carrier reflectivity under the condition of the general degeneracy, the lattice contribution to the slope being taken into account. Theoretical values of the effective masses in the (000) conduction band as a function of alloy composition were calculated for the alloy system GaAs xSb1-x using the disorder equation (73W) and Kane equation (57K) for the effective masses. The experimental results were found to be in better agreement with the disorder equation of the effective mass than with the Kane equation. Finally, to complete the outline of the project, it should be mentioned that the values of optical Fermi energy, dielectric constant, optical relaxation time, optical mobility and optical conductivity were calculated for 12 samples of the alloys GaAsxSb1-x and Ga1-xAl xAs.
The effects of moderating variables on the functions of observational learning

Subjects: subject: Health Sciences, Recreation.

description: This study investigated the effects of gender, competitive level, and sport type on athletes' use of the functions of observational learning (OL): skill, strategy, and performance. Similar studies on OL (as well as imagery) have either compared OL use between athletes in team and individual sports, or independent and interactive sports. However, the author of the current study felt that these classifications were too general and led to the under representation of certain sports. Therefore the current study used more precise classifications of sport type than has been used thus far. This included an Action component made up of independent and interactive levels, and a Structural component consisting of individual and team levels. The Functions of Observational Learning Questionnaire (FOLQ) was administered to 917 male (n = 465) and female (n = 452) athletes participating in a variety of sports at three levels of competition: novice (n = 410), intermediate (n = 339), and proficient (n = 178). Significant differences in OL use were found between independent and interactive sports (p < .01), and a significant three way interaction was found between the Action and Structure dimensions of sport type, and the OL Function (p < .05). Furthermore, a significant Competitive Level by Function interaction showed differences in the use of the skill function of OL, and a Gender by Function interaction showed a difference in the use of the skill and strategy functions of OL between males and females. Finally, support was found for the results of previous research indicating that the skill function of OL was used significantly more than both the strategy and performance function, while the strategy function was used significantly more than the performance function as well across all sport types and levels of competition.

description: In order to study $\beta$-adrenergic regulation of Na$\sp+$ transport in heart, a method was developed to directly measure intracellular free-Na$\sp+$ concentration ($\rm\lbrack Na\sp+\rbrack\sb{i}$) in ventricular myocytes freshly isolated from adult rabbit heart. The approach consisted of injecting the Na$\sp+$-sensitive fluorescent indicator SBFI by iontophoresis, and the simultaneous measurement of transmembrane ion current through the use of a single electrode voltage-clamp technique. Using this approach, steady-state $\rm\lbrack Na\sp+\rbrack\sb{i}$ was found to be 6.4 $\pm$ 1.8 mM in myocytes superfused at 37$\sp\circ$C with modified Tyrode's solution containing 2 mM Ca$\sp{2+}$. Decreasing Ca$\sp{2+}$ concentration to 0.8 mM caused an increase of $\rm\lbrack Na\sp+\rbrack\sb{i}$ to 13.0 $\pm$ 1.4 mM. The $\beta$-adrenergic agonist isoproterenol (ISO), when applied at a concentration of 0.5 $\mu$M, failed to cause any detectable change of steady-state $\rm\lbrack Na\sp+\rbrack\sb{i}$ or transmembrane current. To test whether this lack of effect also occurred at higher $\rm\lbrack Na\sp+\rbrack\sb{i}$, cells were exposed to the cation-selective ionophore gramicidin (10 nM), which induced a slow but continuous increase in $\rm\lbrack Na\sp+\rbrack\sb{i}.$ Under those conditions, ISO caused a decrease or even reversed the gramicidin-induced $\rm\lbrack Na\sp+\rbrack\sb{i}$ rise, while inducing an outward shift of the transmembrane current. These relative changes induced by ISO were not significantly affected by the removal of extracellular Ca$\sp{2+}$; $-$8.0 $\pm$ 2.5 mM/min for the ISO-induced changes in $\rm\lbrack Na\sp+\rbrack\sb{i}$ rate of rise, and 58 $\pm$ 17 pA for the transmembrane current. Under those conditions, strophanthidin (100 $\mu$M) completely inhibited the effects of ISO. Washout of intracellular Ca$\sp{2+}$ by prolonged preincubation of the myocytes in solutions containing 0 mM Ca$\sp{2+}$, 0.5 mM EGTA and 25 $\mu$M BAPTA-AM caused an important attenuation of the effects of ISO.

description: Column leaching tests are frequently used and accepted for investigation of release of hazardous substances from solid materials. Independent of differences due to the field of application or national regulations, column tests assume that local equilibrium is established in the experiment which facilitates transfer of results to field conditions. In the process of harmonization and standardization within Europe the question on the influence of flow rate and grain size distribution on the local equilibrium was raised. Thus, a set of experiments using two different masonry materials with varying grain size distribution and flow rate were conducted including stop/flow experiments. Results are compared to a numerical model which takes intraparticle pore diffusion-controlled release of Mo and V into the percolating water into account. Due to the relatively high intraparticle porosity of the materials (24-29%) data and model indicate that initially equilibrium-state conditions prevail followed by rapidly decreasing concentrations. The model fits data for Mo and V reasonably well; however, after the initial decline of concentrations (at L/S>2) extended tailing is observed especially of elements occurring as oxides, which is not captured by the model. © 2020 Springer Nature Switzerland AG

description: Intensive research efforts are currently directed toward special robotic applications. One of the largest international projects with a focus on this research is the Space Station Freedom. Canada's contribution to this project is a Mobile Servicing System (MSS). This system will be used for assembly and maintenance of the space station. The MSS will consist of a long single arm with a dual-arm robot attached to its end. They require a hierarchical controller to coordinate the arms while executing such tasks as trajectory generation, arm-arm collision avoidance, arm-obstacle collision avoidance, and the manipulation of solid and flexible body payloads. This thesis presents the research work for building a functional hardware and software model of a test-bed dual-arm robot with flexible object handling capabilities using impedance control. It addresses issues such as input-output linearization, perturbation observer, sensor fusion, and provides the experimental results of a dual-arm manipulator using the proposed techniques. To date, no work exists which shows that the application of a dual-arm robot handling flexible payloads in space applications is possible.

description: Einführung: Der häufigste primäre Hirntumor bei Erwachsenen ist das Glioblastom, welches durch ein aggressives Wachstum und eine schlechte Prognose gekennzeichnet ist. Zelluläre Immuntherapien haben in jüngster Vergangenheit große Erfolge bei der Behandlung von hämatologischen Tumoren erzielt. Jedoch blieb ein erfolgreicher Einsatz bei soliden Tumoren, wie dem Glioblastom, bisher hinter den Erwartungen zurück. In diesem Kontext konnte eine vermehrte Expression von CD276, ein Immuncheckpoint, in Glioblastomzellen nachgewiesen werden. Für zelluläre Immuntherapien, wie der CAR NK-92 Zelltherapie, stellt dieses Protein ein vielversprechendes Zielantigen dar. Diese Arbeit soll die Abhängigkeit der CD276-CAR NK-Zelltherapie vom Zielantigen betrachten und mögliche Effekte einer vorab Bestrahlung der Zielzellen auf diese Therapie untersuchen. Methoden: Es wurden mesenchymale und proneurale pGSZ-Kulturen auf ihre CD276-mRNA Abundanz und CD276 Oberflächenexpression hin untersucht. Zusätzlich wurden die Tumorzellen mit CD276-CAR NK-92 Zellen inkubiert und deren Lysierungsgrad mittels Calcein Release Assay bestimmt. Die pGSZ-Kulturen wurden nach verschiedenen Bestrahlungsprotokollen behandelt und die genannten Parameter erhoben. Abschließend wurde mittels siRNA die CD276 Oberflächenexpression der pGSZ-Kulturen herunterreguliert und die Lyseaktivität der CD276-CAR NK-92 bestimmt. Ergebnisse: Während die CD276-mRNA Abundanz keine Veränderung nach Bestrahlung aufwies, konnte die CD276 Oberflächenexpression in allen Zelllinien gesteigert werden. Zudem zeigten die CD276-CAR NK-92 Zellen bei allen pGSZ-Kulturen hohe Lyseaktivität, welche jedoch nicht durch eine Vorabbestrahlung der Tumorzellen gesteigert werden konnte. Darüber hinaus führte eine deutliche Herunterregulierung der CD276 Oberflächenexpression auf den pGSZ-Kulturen nur zu geringen Verlust der Lyseaktivtät der CD276-CAR NK-92 Zellen. Die auftretenden Effekte unterschieden sich kaum zwischen den molekularen Subgruppen. Fazit: Es konnte eine ausgeprägte zytotoxische Wirksamkeit von CD276-CAR NK-92 Zellen gegen alle Primärkulturen von mesenchymalen und proneuralen Glioblastomstammzellen gezeigt werden, unabhängig vom CD276-Expressionslevel. Zudem legen die gezeigten Daten nahe, dass eine Vorabbestrahlung der Tumorzellen die zelluläre Immuntherapie mit CD276-CAR NK-92 wahrscheinlich nicht verstärken würde, trotz Hochregulation der CD276-Oberflächenexpression. Andere CD276 spezifische Immuntherapien könnten bei größere Antigenabhängigkeit jedoch von der Hochregulation profitieren.

description: Background: The purpose of this review is to update previously published reviews on exercise programming in exercise trials in prostate cancer survivors. We evaluated: 1) the application of the principles of exercise training in prescribed programs; 2) the reporting of the components of the exercise prescription; and 3) the reporting of adherence of participants to the prescribed programs. Methods: Building upon a previous review, a systematic review was conducted searching OVID Medline, Embase, CINAHL, and SPORTDiscus databases from 2012-2017. Randomized controlled trials of at least four weeks of aerobic and/or resistance exercise in men diagnosed with prostate cancer that reported physical fitness outcomes, including body composition were eligible for inclusion. Results: Specificity was appropriately applied by 93%, progression by 55%, overload by 48%, initial values by 55%, and diminishing returns by 28% of eligible studies. No study adequately applied the principle of reversibility. Most (79%) studies reported all components of the exercise prescription in the study methods, but no study reported all components of adherence to the prescribed intervention in the study results. Conclusions: Application of standard exercise training principles is inadequate in exercise trials in men with prostate cancer and could possibly lead to an inadequate exercise stimulus. While many studies report the basic components of the exercise prescription in their study methods, full reporting of actual exercise completed is needed to advance our understanding of the optimal exercise dose for men with prostate cancer and promote translation of controlled trials to practice.

Who goes there? Demographics, personality and attachment style of those involved in internet affairs

description: The overall aim of this thesis was to explore the impact of Internet relationships on regular ongoing relationships from the point of view of those engaged in such relationships. Two studies were conducted. A sample of 75 participants, including 22 females and 53 males who were married or living in defacto relationships and ranging in age from 18 to 75 years completed an anonymous online survey for Study One. Demographic characteristics, frequency and method of communication and relationship satisfaction were investigated. Questions were asked about Internet relationship formation. Respondents were asked to gauge levels of self-disclosure within their regular ongoing relationship and their online relationship. They were also asked about the proximity and physical attractiveness of their online partner. It was found that most respondents communicated daily, were more satisfied with their Internet partner than their regular ongoing partner, considered their Internet partner physically attractive and communicated in a highly intimate manner. The purpose of the second study was to investigate the similarities and differences between the personality characteristics and attachment styles of respondents. Participants in the second study were 133 respondents who were married or living in defacto relationships, including 47 females and 86 males ranging in age from 18 years to 66 years. Respondents completed an anonymous online survey, which included measures of personality (e.g. the International Personality Item Pool, Goldberg, 1999), the Relationship Satisfaction questionnaire (Hendrick, 1988), and the Experiences in Close Relationships Scale (Brennan, Clark, & Shaver, 1998). Respondents were found to be somewhat more agreeable and conscientious, and less narcissistic than previous research had found to be the case for those individuals who engaged in face-to-face infidelity. The preoccupied attachment group was well represented, but was less differentiated from the other attachment groups than was the fearful group, who were mainly female. The personality profile and attachment style of respondents in Study Two was, therefore, found to be different in important ways from that which has been associated with face-to-face infidelity. Findings were discussed in terms of methodological implications, suggestions for future research and also implications for Counselling Psychologists.
Internal work measurement and simultaneous oxygen consumption of impaired and normal walking.

Subjects: subject: Applied Mechanics.

description: This study evaluated the ability of two different methods of measuring mechanical work, absolute power (AP) and absolute work (AW), to distinguish between normal and impaired gait. The relation between these two measures was examined as well as their relation to oxygen consumption. Global work measures from all three were compared and, in the case of the absolute power method individual joint power curves of the ankle, knee and hip, for normal and two impaired conditions were examined. Four subjects of each gender were examined for one full gait cycle, by three video cameras, over two AMTI force platforms, under three conditions; normal, locked knee and locked ankle. Oxygen consumption was measured with a TEEM 100 unit carried by the subject in a "fanny" pack. Five normal gait and one trial of each impaired condition were analysed. (Abstract shortened by UMI.)

The role of the 5'-untranslated region in regulating the expression of utrophin in skeletal muscle cells

description: Up-regulating utrophin expression at the sarcolemma is thought to be a key therapeutic approach in the fight against DMD. Utrophin was found to have two isoforms which differ mainly in their 5'-untranslated regions. Effects of the utrophin 5'UTRs on reportergene expression in cell culture and muscle injection experiments were assayed by measuring both reporter transcript and protein levels. Translation efficiencies were estimated by calculating transcript to protein ratios. Our results indicate that there is considerable translation inhibition in control muscle. In comparison, significantly divergent translation efficiencies in regenerating muscle indicate a direct correlation between transcript and protein levels, as seen in cell culture. Furthermore, low levels of translational inhibition are present in adult mdx mice, yet it is significantly de-repressed in young mdx muscle. Taken together, our results suggest that, via the utrophin 5'UTRs, translational regulation is involved in regulating utrophin expression.
