The Psychology Of Competition: A Social Comparison Perspective, Stephen M. Garcia, Avishalom Tor, Tyrone M. Schiff Nov 2013

The Psychology Of Competition: A Social Comparison Perspective, Stephen M. Garcia, Avishalom Tor, Tyrone M. Schiff

Journal Articles

Social comparison—the tendency to self-evaluate by comparing ourselves to others—is an important source of competitive behavior. We propose a new model that distinguishes between individual and situational factors that increase social comparison and thus lead to a range of competitive attitudes and behavior. Individual factors are those that vary from person to person: the relevance of the performance dimension, the similarity of rivals, and their relationship closeness to the individual, as well as the various individual differences variables relating to social comparison more generally. Situational factors, conversely, are those factors on the social comparison landscape that affect similarly ...


Children First: It’S Time To Change! Mental Health Promotion, Prevention, And Treatment Informed By Public Health, And Resiliency Approaches, Vicki Schwean, Susan Rodger Mar 2013

Children First: It’S Time To Change! Mental Health Promotion, Prevention, And Treatment Informed By Public Health, And Resiliency Approaches, Vicki Schwean, Susan Rodger

Journal Articles

Although the importance of healthy mental development in children and youth is not disputed, the mental health needs of far too many Canadian children are being ignored. Within the context of recent federal and provincial calls for systemic reform of the mental health care systems for children and youth, we underscore the necessity for ongoing innovation, development, education, and evaluation. This article describes our aims to establish demonstration and research sites focused on promising frameworks that draw from systems of care, public health, and resiliency approaches.

Journal Articles

PURPOSE: To compare utility of T2-weighted (T2W) MRI and diffusion-weighted MRI (DWI-MRI) obtained with and without an endorectal coil at 3 Tesla (T) for localizing prostate cancer. MATERIALS AND METHODS: This Institutional Review Board-approved study included 20 patients (median prostate-specific antigen, 8.4 ng/mL). Patients underwent consecutive prostate MRIs at 3T, first with a surface coil alone, then with combination of surface, endorectal coils (dual coil) followed by robotic assisted radical prostatectomy. Lesions were mapped at time of acquisition on dual-coil T2W, DWI-MRI. To avoid bias, 6 months later nonendorectal coil T2W, DWI-MRI were mapped. Both MRI evaluations were ...

Absence Of Exposed Bone Following Dental Extraction In Beagle Dogs Treated With 9 Months Of High-Dose Zoledronic Acid Combined With Dexamethasone, M. R. Allen, T. M. G. Chu, S. L. Ruggiero

Journal Articles

Purpose: Factors contributing to osteonecrosis of the jaw with anti-remodeling drug treatment are unclear. Epidemiologic and experimental studies have suggested the combination of bisphosphonates and dexamethasone results in osteonecrosis of the jaw more often than either agent alone. The goal of this study was to assess the combination of these 2 drugs in a large animal model previously shown to be susceptible to exposed bone in the oral cavity when treated with bisphosphonates. Materials and Methods: Skeletally mature beagle dogs were untreated controls or treated with zoledronic acid (ZOL), dexamethasone (DEX), or ZOL plus DEX. ZOL and DEX were given ...

Journal Articles

Objective. Ovarian cancers are highly heterogeneous and while chemotherapy is the preferred treatment many patients are intrinsically resistant or quickly develop resistance. Furthermore, all tumors that recur ultimately become resistant. Recent evidence suggests that epigenetic deregulation may be a key factor in the onset and maintenance of chemoresistance. We set out to identify epigenetically silenced genes that affect chemoresistance. Methods. The epigenomes of a total of 45 ovarian samples were analyzed to identify epigenetically altered genes that segregate with platinum response, and further filtered with expression data to identify genes that were suppressed. A tissue culture carboplatin resistance screen was ...

Protein-Tyrosine Phosphatase 1b Antagonized Signaling By Insulin-Like Growth Factor-1 Receptor And Kinase Brk/Ptk6 In Ovarian Cancer Cells, G. F. Fan, G. Lin, R. Lucito, N. K. Tonks

Journal Articles

Ovarian cancer, which is the leading cause of death from gynecological malignancies, is a heterogeneous disease known to be associated with disruption of multiple signaling pathways. Nevertheless, little is known regarding the role of protein phosphatases in the signaling events that underlie the disease; such knowledge will be essential to gain a complete understanding of the etiology of the disease and how to treat it. We have demonstrated that protein-tyrosine phosphatase 1B (PTP1B) was underexpressed in a panel of ovarian carcinoma-derived cell lines, compared with immortalized human ovarian surface epithelial cell lines. Stable restoration of PTP1B in those cancer cell ...

BACKGROUND: Meningiomas often harbor an immune cell infiltrate that can include substantial numbers of T and B cells. However, their phenotype and characteristics remain undefined. To gain a deeper understanding of the T and B cell repertoire in this tumor, we characterized the immune infiltrate of 28 resected meningiomas representing all grades. METHODS: Immunohistochemistry was used to grossly characterize and enumerate infiltrating lymphocytes. A molecular analysis of the immunoglobulin variable region of tumor-infiltrating B cells was used to characterize their antigen experience. Flow cytometry of fresh tissue homogenate and paired peripheral blood lymphocytes was used to identify T cell phenotypes ...


Interactions Between Estradiol, Bdnf And Dendritic Spines In Promoting Memory., V. Luine, M. Frankfurt Jan 2013

Interactions Between Estradiol, Bdnf And Dendritic Spines In Promoting Memory., V. Luine, M. Frankfurt

Journal Articles

Several lines of evidence have converged to indicate that memory formation involves plasticity of dendritic spines in the medial prefrontal cortex (PFC) and the hippocampus. Memory varies with estrogen levels throughout the lifespan of the female. Generally, increased levels of estrogen are related to greater dendritic spine density on pyramidal cells in the PFC and the hippocampus and to improved memory function. Brain-derived neurotrophic factor (BDNF) is a growth factor which increases dendritic spines and enhances memory function. Estrogens increase BDNF levels in the PFC and the hippocampus. In the present review we provide evidence that estradiol and BDNF may ...


Age-Dependent Effects Of A53t Alpha-Synuclein On Behavior And Dopaminergic Function, A. W. Oaks, M. Frankfurt, D. I. Finkelstein, A. Sidhu Jan 2013

Age-Dependent Effects Of A53t Alpha-Synuclein On Behavior And Dopaminergic Function, A. W. Oaks, M. Frankfurt, D. I. Finkelstein, A. Sidhu

Journal Articles

Expression of A53T mutant human alpha-synuclein under the mouse prion promoter is among the most successful transgenic models of Parkinson's disease. Accumulation of A53T alpha-synuclein causes adult mice to develop severe motor impairment resulting in early death at 8-12 months of age. In younger, pre-symptomatic animals, altered motor activity and anxiety-like behaviors have also been reported. These behavioral changes, which precede severe neuropathology, may stem from non-pathological functions of alpha-synuclein, including modulation of monoamine neurotransmission. Our analysis over the adult life-span of motor activity, anxiety-like, and depressive-like behaviors identifies perturbations both before and after the onset of disease. Young ...

Two Distinct Categories Of Focal Deletions In Cancer Genomes, M. Rajaram, M. Kato, L. Myeroff, S. D. Markowitz, S. W. Lowe, M. Zhang, A. Krasnitz, R. Lucito, D. Mu, R. S. Powers, +13 Additional Authors

Journal Articles

One of the key questions about genomic alterations in cancer is whether they are functional in the sense of contributing to the selective advantage of tumor cells. The frequency with which an alteration occurs might reflect its ability to increase cancer cell growth, or alternatively, enhanced instability of a locus may increase the frequency with which it is found to be aberrant in tumors, regardless of oncogenic impact. Here we've addressed this on a genome-wide scale for cancer-associated focal deletions, which are known to pinpoint both tumor suppressor genes (tumor suppressors) and unstable loci. Based on DNA copy number ...
