Cohort studies have suggested that the use of statins is associated with decreased risk of glioma formation and mortality. Here, a cohort of patients with glioblastoma multiforme (GBM) was analyzed to further investigate associations between preoperative use of statins and recurrence, and progression free and overall survival. Patients who had surgery for GBM (N=284) were followed up for a medi...

We discuss waves created in relatively thick plates by edge excitation at frequency-thickness (fd) products that correspond, in principle, to multiple Lamb wave modes. For relatively low values of the fd product it is clear that Lamb wave modes will be generated, while at large values of the fd product we observe a bulk (longitudinal wave) in the solid, but influenced by reflections from the pl...

Recent work has shown that the same neural circuitry that typically underlies risky behaviors also contributes to prosocial behaviors. Despite the striking overlap between two seemingly distinct behavioral patterns, little is known about how risk taking and prosociality interact and inform adolescent decision making. We review literature on adolescent brain development as it pertains to risk ta...

This paper examined the relationship of three aspects of personality to sexual risk-taking in gay men: (1). sexual arousability, as propensity for sexual excitation, and propensity for inhibition of sexual arousal in the face of threat (measured by the Sexual Excitation, SES, and Sexual Inhibition, SIS1, SIS2, scales); (2). the relation between negative mood and sexuality; and (3). sensation se...

Previous studies have identified several neuroadaptations to chronic drug use, but relatively few have been functionally linked to addiction-related changes in drug-taking and -seeking behaviors. This article summarizes our past and present studies on the contribution of drug-induced neuroadaptations in the mesolimbic dopamine system to addiction-related changes in drug self-administration and ...

The Initiative of establishing Information Technology (IT) and Community Service Centers, later renamed Knowledge Stations (KSs) was launched in 2001. The KSs initiative is intended to implement IT in local communities (LCs) and remote areas in preparation for the E-Government process. This study develops a model that explores KSs’ role as a partnership in E-Government readiness in Jordan throu...

In this perspective article, we consider the relationship between experience sharing and turn-taking. There is much evidence suggesting that human social interaction is permeated by two temporal organizations: (1) the sequential framework of turn-taking and (2) the concurrent framework of emotional reciprocity. From this perspective, we introduce two alternative hypotheses about how the relatio...

Young adults (ages 18-26) with (n = 20) and without (n = 55) a history of child abuse (CA) completed self-report and laboratory-based measures of impulsivity and risk-taking. Relative to individuals without abuse histories, individuals with a history of CA self-reported a greater number of lifetime sexual partners as well as elevated trait impulsivity (specifically, elevated lack of premeditati...

INTRODUCTION The aim of this study is to investigate the nature of the link associating the risk propensity of smoking and overweight. For example, a person who is a smoker and obese does not have to be more prone to risk than another person who is obese and a non-smoker. MATERIAL AND METHODS The data was taken from the German Questionnaire on Personality and Daily (Cross section for the peri...

OBJECTIVE Debate has focused on the effects of the selective serotonin reuptake inhibitor (SSRI) antidepressants on heart rate (HR) and HR variability (HRV), both of which are predictors of adverse cardiovascular events. Here, we examine the associations between specific SSRI antidepressants and resting state HR (and HRV) after accounting for a host of potential confounding factors using propen...
