Previous work has shown that the asymmetric triazine analogue of uridine, 6-azauracil riboside (azauridine), is a much more potent inhibitor of the growth of transplantable mouse tumors than is 6-azauracil (1,2). Presumably this difference in activity reflects the limited extent of the conversion of azauracil to azauridine in mammalian systems (3). On the other hand, formation of the 5’-phospha...

Sexual arousal is a motivational state that moves humans toward situations that inherently pose a risk of disease transmission. Disgust is an emotion that adaptively moves humans away from such situations. Incongruent is the fact that sexual activity is elementary to human fitness yet involves strong disgust elicitors. Using an experimental paradigm, we investigated how these two states interac...

This study examined the effects of the nitric oxide-precursor L-arginine combined with the alpha 2-blocker yohimbine on subjective and physiological sexual arousal in postmenopausal women with Female Sexual Arousal Disorder. Twenty-four women participated in three treatment sessions in which self-report and physiological (vaginal photoplethysmograph) sexual responses to erotic stimuli were meas...

Poetry is one of the seven arts and critics have always attended to its aesthetic features. The greatest modern scientific achievement of literature has been the discovery of the therapeutic quality of poetry. Poetry therapy as a new treatment for patients suffering from depression began in the US where it produced positive results. In this article, the authors investigate poetry in a different...

The hierarchy of classical Chinese poetry has been broadly acknowledged by a number of studies in Chinese literature. However, quantitative investigations about the evolution of classical Chinese poetry are limited. The primary goal of this study is to provide quantitative evidence of the evolutionary linkages, with emphasis on word usage, among different period genres for classical Chinese poe...

In his article "Electronic Poetry and the Importance of Digital Repository" Manuel Brito analyzes selected early digital repositories of electronic poetry. In addition to issues concerning efficiency and discursive practice, Brito's discusses the objectives, contents, and the funding of digital repositories. Brito argues that digital repositories promote poetry, enable networking and quick publ...

Poetry is rarely a focus of linguistic investigation. This is far from surprising, as poetic language, especially in modern and contemporary literature, seems to defy the general rules of syntax and semantics. This paper assumes, however, that linguistic theories should ideally be able to account for creative uses of language, down to their most difficult incarnations. It proposes that at the s...

BACKGROUND Experimental research has shown that emotional stimuli can either enhance or impair attentional performance. However, the relative effects of specific emotional stimuli and the specific time course of these differential effects are unclear. METHODOLOGY/PRINCIPAL FINDINGS In the present study, participants (n = 50) searched for a single target within a rapid serial visual presentati...

In her paper, "Postcolonial African Consciousness and the Poetry of Agostinho Neto," Irene Marques introduces the magic words of a great poet with the question: can poetry carry enough sorrow, enough strength, enough fire, enough love, enough wisdom, enough care, and enough horror to penetrate the hearts and the souls of the oppressed and the oppressors so that both will desperately want to esc...

Lipoproteins of rat plasma have been characterized by lipid analysis, preparative ultracentrifugation, electrophoresis on paper, and immunoelectrophoresis with specific antisera to Lu-lipoprotein, P-lipoprotein, and whole rat plasma. Similar techniques were used to characterize the lipoproteins released by livers perfused in situ with a suspension of erythrocytes in a medium initially free of r...
