Sharon Jakobwitz, Vincent Egan, The dark triad and normal personality traits, Personality and Individual Differences, Volume 40, Issue 2, January 2006, Pages 331-339, ISSN 0191-8869, 10.1016/j.paid.2005.07.006.
>Machiavellianism, Narcissism and Psychopathy are often referred to as the ‘dark triad’ of personality. We examined the degree to which these constructs could be identified in 82 persons recruited from the general population, predicting that the dark triad would emerge as a single dimension denoting the cardinal interpersonal elements of primary psychopathy. We expected the primary psychopathy dimension to correlate negatively with Agreeableness (A) and Conscientiousness (C), whereas secondary psychopathy would be associated with Neuroticism (N). The negative correlation was found between primary psychopathy and A, but not with C. While the predicted correlation between secondary psychopathy and N was found, N was also positively associated with primary psychopathy and Machiavellianism. Factor analysis revealed that all measures of the dark triad loaded positively on the same factor, upon which A loaded negatively. Secondary psychopathy loaded positively on a second factor, together with N and (negatively) with C. These findings reiterate the distinguishing properties of secondary psychopathy, impulsivity and anti-social behaviour relative to primary psychopathy. Thus, even in the general population, the dark dimension of personality can be described in terms of low A, whereas much of the anti-social behaviour in normal persons appears underpinned by high N and low C.

Genome-Wide Expression Analyses of Gene Regulation during Early Development of Dictyostelium discoideum

>Using genome-wide microarrays, we recognized 172 genes that are highly expressed at one stage or another during multicellular development of Dictyostelium discoideum. When developed in shaken suspension, 125 of these genes were expressed if the cells were treated with cyclic AMP (cAMP) pulses at 6-min intervals between 2 and 6 h of development followed by high levels of exogenous cAMP. In the absence of cAMP treatment, only three genes, carA, gbaB, and pdsA, were consistently expressed. Surprisingly, 14 other genes were induced by cAMP treatment of mutant cells lacking the activatable adenylyl cyclase, ACA. However, these genes were not cAMP induced if both of the developmental adenylyl cyclases, ACA and ACR, were disrupted, showing that they depend on an internal source of cAMP. Constitutive activity of the cAMP-dependent protein kinase PKA was found to bypass the requirement of these genes for adenylyl cyclase and cAMP pulses, demonstrating the critical role of PKA in transducing the cAMP signal to early gene expression. In the absence of constitutive PKA activity, expression of later genes was strictly dependent on ACA in pulsed cells.

Sadly I'm at home for the holidays so don't have access to the paper itself to post. It's proved bloody useful for primer design though

Self-Reports of "Positive" Childhood and Adolescent Sexual Contacts With Older Persons: An Exploratory Study (1991) by Paul Okami

>Findings of unusually high percentages of females as older partners in positively rated experiences, and findings that both male and female subjects tended to rate experiences with older females more positively than experiences with older males, suggest that contacts involving women may tend to be experienced more positively by young persons of either gender. Results are, in this respect, consistent with Condy et al. (1987), who found that the majority of their samples both of college males and incarcerated males reported positive responses and beneficial long-term effects from their childhood or adolescent sexual contacts with adult females. In the present study, unusually high percentages of females reported as adult partners of the nonclinical sample overall may also generally support Groth's (1982) suggestion that experiences involving older females as partners/assailants tend to go underreported.

Neurons typically settle at positions that match the location of their synaptic targets, creating topographic maps. In the spinal cord, the organization of motor neurons into discrete clusters is linked to the location of their muscle targets, establishing a topographic map of punctate design. To define the significance of motor pool organization for neuromuscular map formation, we assessed the role of cadherin-catenin signaling in motor neuron positioning and limb muscle innervation. We find that joint inactivation of β- and γ-catenin scrambles motor neuron settling position in the spinal cord but fails to erode the predictive link between motor neuron transcriptional identity and muscle target. Inactivation of N-cadherin perturbs pool positioning in similar ways, albeit with reduced penetrance. These findings reveal that cadherin-catenin signaling directs motor pool patterning and imposes topographic order on an underlying identity-based neural map.
