The aim of the study was to explore the relationship between the five global factors and 16 dimensions of Cattell’s personality model and fluid and crystallized intelligence. A total of 105 third graders (45.7% males) of three high schools participated in the research. Fluid intelligence was measured by Raven’s Advanced Progressive Matrices and crystallized intelligence was measured by the Mill Hill Vocabulary Scale. Personality traits were measured by the Sixteen Personality Factor Questionnaire. Anxiety is correlated neither with fluid nor with crystallized intelligence. Extraversion and Self-Control are negatively correlated with fluid intelligence whereas Tough-Mindedness is positively correlated with it. Independence is positively correlated with crystallized intelligence and Tough-Mindedness is negatively correlated with it. Regression analysis reveals that all broad personality factors, except anxiety, are significant predictors of fluid intelligence. When combined together, these factors account for 25% of the variance of fluid intelligence scores. The regression model with crystallized intelligence as a criterion variable is not statistically significant. The study results are consistent with the Chamorro-Premuzic and Furnham’s (2005) two-level conceptual framework. Although using a different taxonomy of personality, the results are in accordance with the model’s presuppositions.

ABSTRACT This study is an extension of earlier research that investigated the nature of homonegativity among Italian people (Lingiardi, Falanga, & D’Augelli, 2005). We used the Modern Homophobia Scale (MHS), adapted to be more appropriate for the Italian social and cultural context. Associations were examined between homophobic attitudes, demographics, and personality characteristics and contact with lesbians and gay men. Gender issues were considered twice, from the viewpoint of both the agent and the target of the prejudice. The findings indicated that people at higher risk of possessing homonegative attitudes are older; less educated; more involved in religion and politically conservative; characterized by a more conforming, moralistic, and rule-bound personality, according to Cattell’s personality factors; and have poor contact experience with lesbians and gay men. Males tended to have higher levels of homonegativity toward gay men but not toward lesbians. Proposals to reduce antigay bias in the Italian context will be briefly discussed.

IL-1 is a potent pro-inflammatory cytokine that activates intracellular signaling cascades some of which may involve IL-1 receptor associated kinase-1 (IRAK1). Psoriasis is a T cell dependent chronic inflammatory condition of the skin of unknown cause. IL-1 has been implicated in psoriasis pathology, but the mechanism has not been elucidated. Interestingly, expression of IRAK1 is elevated in psoriatic skin. To identify a potential link between IL-1, keratinocytes and T cells in skin inflammation we employed pathway-focused microarrays to evaluate IL-1 dependent gene expression in keratinocytes. Several candidate mRNAs encoding known T cell chemoattractants were identified in primary keratinocytes and the stable keratinocyte cell line HaCaT. CCL5 and CCL20 mRNA and protein levels were confirmed up-regulated by IL-1 in concentration and time-dependent manners. Furthermore IL-1 synergized with IFN-γ and TNF-α. Expression of CXCL9, CXCL10 and CXCL11 mRNAs was also increased in response to IL-1, but protein could only be detected in medium from cells treated with IFN-γ alone or in combination with IL-1. Over-expression of IRAK1 led to increased constitutive and cytokine induced production of CCL5 and CCL20. Inhibition of IRAK1 activity through RNAi or expression of a dominant negative mutant blocked production of CCL5 and CCL20 but had no effect upon the IL-1 enhancement of IFN-γ induced CXCL9, CXCL10 and CXCL11 production. In conclusion IL-1 regulates T cell targeting chemokine production in keratinocytes through IRAK1 dependent and independent pathways. These pathways may contribute to acute and chronic skin inflammation.

The ratio between second and fourth finger (2D:4D) is sexually dimorphic; it is lower in men than in women. Studies using broad personality domains yielded correlations of 2D:4D with neuroticism, extraversion or agreeableness, but the obtained results have been inconsistent. We correlated 2D:4D of 184 women and 101 men with their scores in Cattell's 16 Personality Factor (16PF) Questionnaire. We found women with a higher (more ‘feminine’) right hand 2D:4D to score lower in emotional stability and social boldness and higher in privateness. Mediator analysis showed emotional stability to be probably primarily correlated with 2D:4D and to act as a mediator between 2D:4D and social boldness. Privateness appears to be mediated by an even more complex path. We discuss the usefulness of primary‐level personality questionnaires and mediator analyses in the investigation of psycho‐morphological associations. Copyright © 2007 John Wiley & Sons, Ltd.

This study examined the personality characteristics of sixty Schizophrenics with and without criminal record on inpatients of Ranchi Institute of Neuro-Psychiatry and Allied Sciences, Ranchi (RINPAS) India. A comparison of their personality profiles on 16 PF test revealed that Schizophrenics with criminal record were more assertive, less reserved, less conscientious, and more extraverted than Schizophrenics without criminal record. It indicates that Schizophrenics who commit offences may be differentiated from those who are not involved in criminal act on the basis of their personality characteristics.

We report the isolation and partial characterization of a so far unidentified basic platelet protein. Delipidated bovine platelets were extracted at pH 2.1. The extract was subjected to differential precipitation at pH 5.4-5.5 and by ammonium sulfate, then it was further purified by ion exchange chromatography on DEAE and CM cellulose columns in an urea containing medium. The major protein peak eluted from the CM cellulose column by NaCl gradient contained a protein in electrophoretically homogeneous form. It consists of a single polypeptide chain with an Mr of 28,000 as estimated by SDS PAGE. It was shown to be extremely rich in lysine and cystine and possessed a highly basic character (pI 9.8-10.1). On this basis the term cystine-rich basic protein (CRBP) was proposed for the new protein. Unlike some other low Mr basic proteins it did not bind calmodulin and troponin C, however, it showed significant heparin neutralizing activity.
