Oocyte Peptides As Paracrine Tools For Ovarian Stimulation And Oocyte Maturation., David G Mottershead, Andrew J Watson Dec 2009

Oocyte Peptides As Paracrine Tools For Ovarian Stimulation And Oocyte Maturation., David G Mottershead, Andrew J Watson

Obstetrics & Gynaecology Publications

Recent studies report the production and isolation of a stable bioactive recombinant human bone morphogenetic protein 15 (rhBMP15) that is appropriately processed in HEK-293 cells and activates the SMAD 1/5/8 pathway in mouse granulosa cell cultures. Further, the purified rhBMP15 induces the expression of genes associated with cumulus expansion. Thanks to recent research, we have a greater understanding of the importance of the dialogue that occurs between the oocyte and the granulosa cell layer with regard to regulating folliculogenesis and the acquisition of oocyte developmental competence and maturation. BMP15 is one of the critical components of these intra-follicular communication pathways. …


Transnational Understandings Of Australian Aboriginal Sporting Migration: Sporting Walkabout, John Maynard Dec 2009

Transnational Understandings Of Australian Aboriginal Sporting Migration: Sporting Walkabout, John Maynard

Aboriginal Policy Research Consortium International (APRCi)

This article will examine the impact of Aboriginal sporting participation and movement around the globe. The experiences, influences and inspiration that Aboriginal sporting men and women absorbed while travelling internationally have played a prominent role in changing the perceptions and understanding of Aboriginal people to the wider populace. The later stages of the nineteenth and early twentieth century were a period in which Aboriginal people were erroneously categorized as a dying race, belonging to the Stone Age and uneducable. However the influence of sport and travel ensured that Aboriginal cricketers, footballers, athletes, boxers and horsemen and -women played a part …

Resting State Default-Mode Network Connectivity In Early Depression Using A Seed Region-Of-Interest Analysis: Decreased Connectivity With Caudate Nucleus., Robyn Bluhm, Peter Williamson, Ruth Lanius, Jean Theberge, Maria Densmore, Robert Bartha, Richard Neufeld, Elizabeth Osuch Dec 2009

Resting State Default-Mode Network Connectivity In Early Depression Using A Seed Region-Of-Interest Analysis: Decreased Connectivity With Caudate Nucleus., Robyn Bluhm, Peter Williamson, Ruth Lanius, Jean Theberge, Maria Densmore, Robert Bartha, Richard Neufeld, Elizabeth Osuch

Department of Medicine Publications

AIM: Reports on resting brain activity in healthy controls have described a default-mode network (DMN) and important differences in DMN connectivity have emerged for several psychiatric conditions. No study to date, however, has investigated resting-state DMN in relatively early depression before years of medication treatment. The objective of the present study was, therefore, to investigate the DMN in patients seeking help from specialized mental health services for the first time for symptoms of depression.

METHODS: Fourteen depressed subjects and 15 matched controls were scanned using 4-T functional magnetic resonance imaging while resting with eyes closed. All but one subject was …


Adding A Motivational Interviewing Pretreatment To Cognitive Behavioral Therapy For Generalized Anxiety Disorder: A Preliminary Randomized Controlled Trial., Henny A Westra, Hal Arkowitz, David J A Dozois Dec 2009

Adding A Motivational Interviewing Pretreatment To Cognitive Behavioral Therapy For Generalized Anxiety Disorder: A Preliminary Randomized Controlled Trial., Henny A Westra, Hal Arkowitz, David J A Dozois

Psychology Publications

Seventy-six individuals with a principal diagnosis of generalized anxiety disorder (GAD) were randomly assigned to receive either an MI pretreatment or no pretreatment (NPT), prior to receiving CBT. Significant group differences favoring the MI-CBT group were observed on the hallmark GAD symptom of worry and on therapist-rated homework compliance, which mediated the impact of treatment group on worry reduction. Adding MI pretreatment to CBT was specifically and substantively beneficial for individuals with high worry severity at baseline. There was evidence of relapse at 6-month follow-up for high severity individuals who received MI-CBT, but significant moderator effects favoring the high severity …


Changes In Self-Schema Structure In Cognitive Therapy For Major Depressive Disorder: A Randomized Clinical Trial., David J A Dozois, Peter J Bieling, Irene Patelis-Siotis, Lori Hoar, Susan Chudzik, Katie Mccabe, Henny A Westra Dec 2009

Changes In Self-Schema Structure In Cognitive Therapy For Major Depressive Disorder: A Randomized Clinical Trial., David J A Dozois, Peter J Bieling, Irene Patelis-Siotis, Lori Hoar, Susan Chudzik, Katie Mccabe, Henny A Westra

Psychology Publications

Negative cognitive structure (particularly for interpersonal content) has been shown in some research to persist past a current episode of depression and potentially to be a stable marker of vulnerability for depression (D. J. A. Dozois, 2007; D. J. A. Dozois & K. S. Dobson, 2001a). Given that cognitive therapy (CT) is highly effective for treating the acute phase of a depressive episode and that this treatment also reduces the risk of relapse and recurrence, it is possible that CT may alter these stable cognitive structures. In the current study, patients were randomly assigned to CT+ pharmacotherapy (n = 21) …


Worker Control As A Facilitator In The Match Between Education And Jobs, Johanna Weststar Nov 2009

Worker Control As A Facilitator In The Match Between Education And Jobs, Johanna Weststar

Management and Organizational Studies Publications

This article examines the relationship between worker control and subjective underemployment among workers who have more education than is needed for entry into their jobs (credential underemployment). Results indicate that social and technical controls are related to a greater sense of education–job matching. Workers who have credential underemployment are less likely to report subjective underemployment (underutilization and lack of fit between education and job) if they have higher levels of workplace control. This article contains implications for job design and the role of employers and managers in fostering the utilization of their workforces.


Electrochemical And Photovoltaic Properties Of Electropolymerized Poly(Thienyl-Silole)S, Joshua C. Byers, Paul M. Dicarmine, Mahmoud M. A. R. Moustafa, Xin Wang, Brian Pagenkopf, Oleg A. Semenikhin Nov 2009

Electrochemical And Photovoltaic Properties Of Electropolymerized Poly(Thienyl-Silole)S, Joshua C. Byers, Paul M. Dicarmine, Mahmoud M. A. R. Moustafa, Xin Wang, Brian Pagenkopf, Oleg A. Semenikhin

Chemistry Publications

Electrochemical and photoelectrochemical properties were studied of a series of donor−acceptor materials based on polythiophene modified with silole moieties. The materials were prepared by electrochemical anodic polymerization of 2,5-bis([2,2′-bithiophen]-5-yl)-1,1-dimethyl-3,4-diphenylsilole and 2,5-bis([2,2′-terthiophen]-5-yl)-1,1-dimethyl-3,4-diphenylsilole, as well as copolymerization of these monomers with 2,2′-bithiophene. Photocurrent measurements showed that introduction of silole resulted in a considerable enhancement of the photovoltaic properties of silole-containing materials and especially the fill factor. However, as demonstrated by Mott−Schottky measurements, electropolymerized silole-containing materials showed a substantial degree of disorder and high density of states in the midgap, which negatively affected their photovoltaic properties. Atomic force microscopy (AFM) and phase imaging …

The Effects Of Field-Of-View And Patient Size On Ct Numbers From Cone-Beam Computed Tomography., Katrina Y T Seet, Arvand Barghi, Slav Yartsev, Jacob Van Dyk Oct 2009

The Effects Of Field-Of-View And Patient Size On Ct Numbers From Cone-Beam Computed Tomography., Katrina Y T Seet, Arvand Barghi, Slav Yartsev, Jacob Van Dyk

Oncology Publications

Cone-beam computed tomography (CBCT) is used for patient alignment before treatment and is ideal for use in adaptive radiotherapy to account for tumor shrinkage, organ deformation and weight loss. However, CBCT images are prone to artifacts such as streaking and cupping effects, reducing image quality and CT number accuracy. Our goal was to determine the optimum combination of cone-beam imaging options to increase the accuracy of image CT numbers. Several phantoms with and without inserts of known relative electron densities were imaged using the Varian on-board imaging system. It was found that CT numbers are most influenced by the selection …

The Lambert W Function And Quantum Statistics, Sree Ram Valluri, M. Gil, D. J. Jeffrey, Shantanu Basu Oct 2009

The Lambert W Function And Quantum Statistics, Sree Ram Valluri, M. Gil, D. J. Jeffrey, Shantanu Basu

Physics and Astronomy Publications

We present some applications of the Lambert W function (W function) to the formalism of quantum statistics (QS). We consider the problem of finding extrema in terms of energy for a general QS distribution, which involves the solution of a transcendental equation in terms of the W function. We then present some applications of this formula including Bose–Einstein systems in d dimensions, Maxwell–Boltzmann systems, and black body radiation. We also show that for the appropriate parameter values, this formula reduces to an analytic expression in connection with Wien’s displacement law that was found in a previous study. In addition, we …


Community-Based Suicide Prevention Research In Remote On-Reserve First Nations Communities, Corinne A. Isaak, Mike Campeau, Laurence Y. Katz, Murray W. Enns, Brenda Elias, Jitender Sareen Oct 2009

Community-Based Suicide Prevention Research In Remote On-Reserve First Nations Communities, Corinne A. Isaak, Mike Campeau, Laurence Y. Katz, Murray W. Enns, Brenda Elias, Jitender Sareen

Aboriginal Policy Research Consortium International (APRCi)

Suicide is a complex problem linked to genetic, environmental, psychological and community factors. For the Aboriginal population more specifically, loss of culture, history of traumatic events, individual, family and community factors may also play a role in suicidal behaviour. Of particular concern is the high rate of suicide among Canadian Aboriginal youth. While the need to develop interventions to reduce suicidal behaviour for First Nations on-reserve populations is evident, there may be an element of distrust of researchers by Aboriginal communities. Furthermore, research in mental health and specifically suicide is much more sensitive than studying medical illnesses like diabetes. Clearly, …

Thomas Greenfield And The Quest For Meaning In Organizations: A Postponed Dialogue With Ludwig Wittgenstein, Gus Riveros Oct 2009

Thomas Greenfield And The Quest For Meaning In Organizations: A Postponed Dialogue With Ludwig Wittgenstein, Gus Riveros

Education Publications

In this paper I highlight the role of the notion of meaning for educational administration. I want draw attention to Thomas Greenfield’s theses regarding the role of meanings in organization. I explore the relations between Greenfield’s thesis about meaning in organization and Ludwig Wittgenstein’s thoughts about language and meaning. I shed some light on the encounters and distances between these two thinkers. My account is both exploratory and critical. On the one hand, I point up the relationships between meaning, practices, and action in organization. On the other hand, I identify one aspect of Greenfield’s thought that can be further …

Adapting To Dynamic Stimulus-Response Values: Differential Contributions Of Inferior Frontal, Dorsomedial, And Dorsolateral Regions Of Prefrontal Cortex To Decision Making., Derek G V Mitchell, Qian Luo, Shelley B Avny, Tomasz Kasprzycki, Karanvir Gupta, Gang Chen, Elizabeth C Finger, R James R Blair Sep 2009

Adapting To Dynamic Stimulus-Response Values: Differential Contributions Of Inferior Frontal, Dorsomedial, And Dorsolateral Regions Of Prefrontal Cortex To Decision Making., Derek G V Mitchell, Qian Luo, Shelley B Avny, Tomasz Kasprzycki, Karanvir Gupta, Gang Chen, Elizabeth C Finger, R James R Blair

Brain and Mind Institute Researchers' Publications

Dorsomedial prefrontal cortex (dmPFC), dorsolateral prefrontal cortex (dlPFC), and inferior frontal gyrus (IFG) have all been implicated in resolving decision conflict whether this conflict is generated by having to select between responses of similar value or by making selections following a reversal in reinforcement contingencies. However, work distinguishing their individual functional contributions remains preliminary. We used functional magnetic resonance imaging to delineate the functional role of these systems with regard to both forms of decision conflict. Within dmPFC and dlPFC, blood oxygen level-dependent responses increased in response to decision conflict regardless of whether the conflict occurred in the context of …


Tobacco Control Interest Groups And Their Influence On Parliamentary Committees In Canada, Robyn E. Hastie, Anita Kothari Sep 2009

Tobacco Control Interest Groups And Their Influence On Parliamentary Committees In Canada, Robyn E. Hastie, Anita Kothari

Health Studies Publications

Objectives: The aim of this study was to determine how tobacco control interest groups influence tobacco policy decision-making through submissions and presentations to parliamentary committees.

Methods: A qualitative content analysis was used to examine the presentations and submissions on tobacco-related legislation made to parliamentary committees between 1996 and 2004. The sample was identified from the public list of tobacco-related bills tabled in both the House of Commons and the Senate; the Government of Canada website and LEGISinfo were used to determine which committee reviewed the relevant bill. Committee clerks were asked to send submissions and presentations related to specific bills …


Neuropeptide Y And Neurovascular Control In Skeletal Muscle And Skin., Gary J Hodges, Dwayne N Jackson, Louis Mattar, John M Johnson, J Kevin Shoemaker Sep 2009

Neuropeptide Y And Neurovascular Control In Skeletal Muscle And Skin., Gary J Hodges, Dwayne N Jackson, Louis Mattar, John M Johnson, J Kevin Shoemaker

Kinesiology Publications

Neuropeptide Y (NPY) is a ubiquitous peptide with multiple effects on energy metabolism, reproduction, neurogenesis, and emotion. In addition, NPY is an important sympathetic neurotransmitter involved in neurovascular regulation. Although early studies suggested that the vasoactive effects of NPY were limited to periods of high stress, there is growing evidence for the involvement of NPY on baseline vasomotor tone and sympathetically evoked vasoconstriction in vivo in both skeletal muscle and the cutaneous circulation. In Sprague-Dawley rat skeletal muscle, Y(1)-receptor activation appears to play an important role in the regulation of basal vascular conductance, and this effect is similar in magnitude …

Beyond Recovery: Colonization, Health And Healing For Indigenous People In Canada, Lynn F. Lavallee, Jennifer M. Poole Aug 2009

Beyond Recovery: Colonization, Health And Healing For Indigenous People In Canada, Lynn F. Lavallee, Jennifer M. Poole

Aboriginal Policy Research Consortium International (APRCi)

How do we limit our focus to mental health when Indigenous teaching demands a much wider lens? How do we respond to mental health recovery when Indigenous experience speaks to a very different approach to healing, and how can we take up the health of Indigenous people in Canada without a discussion of identity and colonization? We cannot, for the mental health and recovery of Indigenous people in Canada have always been tied to history, identity, politics, language and dislocation. Thus, in this paper, our aim is to make clear that history, highlight the impacts of colonization and expound on …


High Aldehyde Dehydrogenase And Expression Of Cancer Stem Cell Markers Selects For Breast Cancer Cells With Enhanced Malignant And Metastatic Ability, Alysha K. Croker, David Goodale, Jenny Chu, Carl Postenka, Benjamin D. Hedley, David A. Hess, Alison L. Allan Aug 2009

High Aldehyde Dehydrogenase And Expression Of Cancer Stem Cell Markers Selects For Breast Cancer Cells With Enhanced Malignant And Metastatic Ability, Alysha K. Croker, David Goodale, Jenny Chu, Carl Postenka, Benjamin D. Hedley, David A. Hess, Alison L. Allan

Anatomy and Cell Biology Publications

Cancer stem cells (CSCs) have recently been identified in leukaemia and solid tumours; however, the role of CSCs in metastasis remains poorly understood. This dearth of knowledge about CSCs and metastasis is due largely to technical challenges associated with the use of primary human cancer cells in pre-clinical models of metastasis. Therefore, the objective of this study was to develop suitable pre-clinical model systems for studying stem-like cells in breast cancer metastasis, and to test the hypothesis that stem-like cells play a key role in metastatic behaviour. We assessed four different human breast cancer cell lines (MDA-MB-435, MDA-MB-231, MDA-MB-468, MCF-7) …
