Dr. Fabrizio Di Stani – Dipartimento di Scienze Neurologiche / Università di Roma “La Sapienza” Roma, Italy. E-mail: [email protected] Cluster headache (CH) is characterised by attacks of severe unilateral pain in the orbital, supraorbital and/or temporal areas that last from 15 to 180 min, with recurrence up to 8 times daily and accompanied by ipsilateral autonomic symptoms. Althoug...

Calcium Hydroxide (CH) is commonly employed as intracanal medicament in endodontics. In order to maximize its therapeutic effects, it is essential to develop new approaches for preparing the controlled drug release systems which, in turn, facilities the dissociation of CH into calcium and hydroxyl ions. This work studies the sustained-controlled release of calcium ions and the effect of pH chan...

BACKGROUND/AIMS Congenital primary hypothyroidism (CH) is a rare pediatric disorder estimated to occur in about 1:2,500 live births. Approximately half of these cases entail ectopic thyroid tissue, which is believed to result from a migration defect during embryogenesis. Approximately 3% of CH cases are explained by mutation(s) in known genes, most of which are transcription factors implicated ...

* This note arose from consultations during the tenure of a John Simon Guggenheim Memorial Fellowship by MacLane. ' Whitehead, J. H. C., "Combinatorial Homotopy I and II," Bull. A.M.S., 55, 214-245 and 453-496 (1949). We refer to these papers as CH I and CH II, respectively. ' By a complex we shall mean a connected CW complex, as defined in §5 of CH I. We do not restrict ourselres to finite com...

studies in cognitive linguistics have highlighted the importance of metaphors for language teaching. metaphoric competence, as an important aspect of intelligence, can contribute to the learning of languages. most textbooks in esl/efl avoid the issue of figurative language and concentrate only on the denotative aspects of language. this article reports a study conducted at the islamic azad univ...

We previously demonstrated augmented endothelium-derived nitric oxide (EDNO)-dependent pulmonary arterial dilation and increased arterial endothelial nitric oxide synthase (eNOS) levels in chronic hypoxic (CH) and monocrotaline (nonhypoxic) models of pulmonary arterial hypertension. Therefore, we hypothesized that the long-term elevation of arterial eNOS levels associated with CH is related to ...

Female rats develop less severe pulmonary hypertension (PH) in response to chronic hypoxia compared with males, thus implicating a potential role for ovarian hormones in mediating this gender difference. Considering that estrogen upregulates endothelial nitric oxide (NO) synthase (eNOS) in systemic vascular tissue, we hypothesized that estrogen inhibits hypoxic PH by increasing eNOS expression ...

The topics treated in The brain and emotion include the definition, nature, and functions of emotion (Ch. 3); the neural bases of emotion (Ch. 4); reward, punishment, and emotion in brain design (Ch. 10); a theory of consciousness and its application to understanding emotion and pleasure (Ch. 9); and neural networks and emotion-related learning (Appendix). The approach is that emotions can be c...

Literature on the relationship of cannabis use and cognition in schizophrenia provides the paradoxical view that cannabis use is sometimes linked with less severe impairment in neurocognition. This paper explored the possibility that this is a reflection of a dose related response between lifetime cannabis use and two forms of cognition, neurocognition and metacognition, in schizophrenia. It wa...
