    Get PDF
    The purpose of this study was to identify personality types among dental hygiene school administrators and faculty and to determine if correlations existed between leader style, ideologies of leader style, perceived effectiveness, and personality type. Selected demographic variables were also examined. The dimensions of personality investigated were derived from the Myers-Briggs Type Indicator: extroversion, introversion, sensing, intuition, thinking, feeling, judging, and perceiving. The leadership behavior dimensions were the two dimensions of the real and ideal Leadership Behavior Description Questionnaires: consideration and initiating structure. Effectiveness was measured by a 39 item Likert-type instrument based on Tucker\u27s (1981) categorical listing of chairperson activities and responsibilities. The study was conducted using a random sample of faculty and administrators from 32 dental hygiene programs across the United States. Thirty-two administrators and 148 faculty were surveyed. Responses were received from 23 administrators (71.9 percent) and 96 faculty (64.8 percent). Personality type was correlated with subordinate perception of leader style, ideal leader style, and effectiveness, with the strength of the relationships ranging from weakly negative to moderately positive. Among the correlations observed, those between real initiating structure and introversion, thinking and feeling were significant at the.05 level, as were the relationships between ideal consideration, and thinking and feeling. Relationships significant at the.05 level were also found between instruction and extroversion, introversion, sensing, intuition, and judging and between budget and resources and extroversion. Gender of the administrator and length of tenure did not account for significant differences in leader behavior ratings or effectiveness scores. Age of the administrator, however, was found to account for significant differences in leader behavior ratings, but not effectiveness ratings. A negative relationship was observed between amount of administrative training and effectiveness scores indicating that as administrative training increased effectiveness decreased. Ideal scores reported by faculty were significantly higher than real scores reported by faculty, but no significant difference was observed between the real and ideal scores reported by administrators. Administrators rating low on real consideration and real initiating structure received the lowest effectiveness ratings

    Oral History, Mobile Curation, and African American Memory in Cleveland\u27s Fairfax and Glenville Neighborhoods

    Get PDF
    Fairfax and Glenville are historic neighborhoods with signal importance in the African American community. Too often these neighborhoods are subjected to a simplistic declension narrative that pins their heyday in the 1920s-50s and traces their decline to the convulsive riots of the late 1960s and the subsequent loss of population to the suburbs as middle-class African Americans mirrored “white flight.” Our team conducted over 40 interviews, created story clips, and curated several new sites for the Cleveland Historical website and mobile application. Our research, rooted in oral history, exposed an important post-1968 counternarrative of resilience. Our oral histories demonstrate a continuing thread of black/white/Jewish collaborative approaches to community issues, particularly in Glenville, as well as the continuing relevance of the “old neighborhoods” for work, play, and worship long after middle-class suburban flight. They also reveal a selective memory that privileges personal connections to the neighborhood through kinship, friendship, faith, and social activism, yielding a “sense of place” that is not always tied to prevailing assumptions about the neighborhoods.https://engagedscholarship.csuohio.edu/u_poster_2014/1007/thumbnail.jp

    Combined TRPC3 and TRPC6 blockade by selective small-molecule or genetic deletion inhibits pathological cardiac hypertrophy

    Get PDF
    Chronic neurohormonal and mechanical stresses are central fea-tures of heart disease. Increasing evidence supports a role forthe transient receptor potential canonical channels TRPC3 andTRPC6 in this pathophysiology. Channel expression for both is nor-mally very low but is increased by cardiac disease, and geneticgain- or loss-of-function studies support contributions to hypertro-phy and dysfunction. Selective small-molecule inhibitors remainscarce, and none target both channels, which may be useful giventhe high homology among them and evidence of redundant sig-naling. Here we tested selective TRPC3/6 antagonists (GSK2332255Band GSK2833503A; IC50,3–21 nM against TRPC3 and TRPC6) andfound dose-dependent blockade of cell hypertrophy signaling trig-gered by angiotensin II or endothelin-1 in HEK293T cells as well as inneonatal and adult cardiac myocytes. In vivo efficacy in mice andrats was greatly limited by rapid metabolism and high protein bind-ing, although antifibrotic effects with pressure overload were ob-served. Intriguingly, although gene deletion of TRPC3 or TRPC6alone did not protect against hypertrophy or dysfunction frompressure overload, combined deletion was protective, support-ing the value of dual inhibition. Further development of thispharmaceutical class may yield a useful therapeutic agent forheart disease management.Fil: Seo, Kinya. Johns Hopkins Medical Institutions.

    Alzheimers disease (AD) is a major public health priority with a large socioeconomic burden and complex etiology. The Alzheimer Disease Metabolomics Consortium (ADMC) and the Alzheimer Disease Neuroimaging Initiative (ADNI) aim to gain new biological insights in the disease etiology. We report here an untargeted lipidomics of serum specimens of 806 subjects within the ADNI1 cohort (188 AD, 392 mild cognitive impairment and 226 cognitively normal subjects) along with 83 quality control samples. Lipids were detected and measured using an ultra-high-performance liquid chromatography quadruple/time-of-flight mass spectrometry (UHPLC-QTOF MS) instrument operated in both negative and positive electrospray ionization modes. The dataset includes a total 513 unique lipid species out of which 341 are known lipids. For over 95% of the detected lipids, a relative standard deviation of better than 20% was achieved in the quality control samples, indicating high technical reproducibility. Association modeling of this dataset and available clinical, metabolomics and drug-use data will provide novel insights into the AD etiology. These datasets are available at the ADNI repository at http://adni.loni.usc.edu/

    So, You Want to Use Next Generation Sequencing In Marine Systems? Insight from the Pan Pacific Advanced Studies Institute

    Get PDF
    The emerging field of next-generation sequencing (NGS) is rapidly expanding capabilities for cutting edge genomic research, with applications that can help meet marine conservation challenges of food security, biodiversity loss, and climate change. Navigating the use of these tools, however, is complex at best. Furthermore, applications of marine genomic questions are limited in developing nations where both marine biodiversity and threats to marine biodiversity are most concentrated. This is particularly true in Southeast Asia. The first Pan-Pacific Advanced Studies Institute (PacASI) entitled Genomic Applications to Marine Science and Resource Management in Southeast Asia was held in July 2012 in Dumaguete, Philippines, with the intent to draw together leading scientists from both sides of the Pacific Ocean to understand the potential of NGS in helping address the aforementioned challenges. Here we synthesize discussions held during the PacASI to provide perspectives and guidance to help scientists new to NGS choose among the variety of available advanced genomic methodologies specifically for marine science questions

    Infections and inflammatory conditions during pregnancy can dysregulate neural development and increase the risk for developing autism and schizophrenia. The following research utilized a nonhuman primate model to investigate the potential impact of a mild endotoxemia during pregnancy on brain maturation and behavioral reactivity as well as the infants’ hormone and immune physiology. Nine pregnant female rhesus monkeys (Macaca mulatta) were administered nanogram concentrations of lipopolysaccharide (LPS) on two consecutive days, six weeks before term, and their offspring were compared to nine control animals. When tested under arousing challenge conditions, infants from the LPS pregnancies were more behaviorally disturbed, including a failure to show a normal attenuation of startle responses on tests of prepulse inhibition. Examination of their brains at one year of age with magnetic resonance imaging (MRI) revealed the unexpected finding of a significant 8.8% increase in global white matter volume distributed across many cortical regions compared to controls. More selective changes in regional gray matter volume and cortical thickness were noted in parietal, medial temporal, and frontal areas. While inhibited neural growth has been described previously after prenatal infection and LPS administration at higher doses in rodents, this low dose endotoxemia in the monkey is the first paradigm to produce a neural phenotype associated with augmented gray and white matter growth

    Interleukin-6 gene (IL-6): a possible role in brain morphology in the healthy adult brain

    Background: Cytokines such as interleukin 6 (IL-6) have been implicated in dual functions in neuropsychiatric disorders. Little is known about the genetic predisposition to neurodegenerative and neuroproliferative properties of cytokine genes. In this study the potential dual role of several IL-6 polymorphisms in brain morphology is investigated. Methodology: In a large sample of healthy individuals (N = 303), associations between genetic variants of IL-6 (rs1800795; rs1800796, rs2069833, rs2069840) and brain volume (gray matter volume) were analyzed using voxel-based morphometry (VBM). Selection of single nucleotide polymorphisms (SNPs) followed a tagging SNP approach (e.g., Stampa algorigthm), yielding a capture 97.08% of the variation in the IL-6 gene using four tagging SNPs. Principal findings/results: In a whole-brain analysis, the polymorphism rs1800795 (−174 C/G) showed a strong main effect of genotype (43 CC vs. 150 CG vs. 100 GG; x = 24, y = −10, z = −15; F(2,286) = 8.54, puncorrected = 0.0002; pAlphaSim-corrected = 0.002; cluster size k = 577) within the right hippocampus head. Homozygous carriers of the G-allele had significantly larger hippocampus gray matter volumes compared to heterozygous subjects. None of the other investigated SNPs showed a significant association with grey matter volume in whole-brain analyses. Conclusions/significance: These findings suggest a possible neuroprotective role of the G-allele of the SNP rs1800795 on hippocampal volumes. Studies on the role of this SNP in psychiatric populations and especially in those with an affected hippocampus (e.g., by maltreatment, stress) are warranted.Bernhard T Baune, Carsten Konrad, Dominik Grotegerd, Thomas Suslow, Eva Birosova, Patricia Ohrmann, Jochen Bauer, Volker Arolt, Walter Heindel, Katharina Domschke, Sonja Schöning, Astrid V Rauch, Christina Uhlmann, Harald Kugel and Udo Dannlowsk
