We present Nada: the Non-Anaphoric Detection Algorithm. Nada is a novel, publicly-available program that accurately distinguishes between the referential and non-referential pronoun it in raw English text. Like recent state-of-the-art approaches, Nada uses very large-scale web N-gram features, but Nada makes these features practical by compressing the N-gram counts so they can fit into computer...
NadA is a novel vaccine candidate recently identified in Neisseria meningitidis and involved in adhesion to host tissues. The nadA gene has been found in approximately 50% of the strains isolated from patients and in three of the four hypervirulent lineages of non-serogroup A strains. Here we investigated the presence of the nadA gene in 154 meningococcal strains isolated from healthy people (c...
The search for an endogenous ligand for the vanilloid receptor (VR or TRPV1) has led to the identification of N-arachidonyl dopamine (NADA). This study investigates the role of protein kinase C (PKC)-mediated phosphorylation on NADA-induced membrane currents in Xenopus oocytes heterologously expressing TRPV1 and in dorsal root ganglion (DRG) neurons. In basal state, current induced by 10 microM...
The endocannabinoid system is a crucial regulator of hepatic fibrogenesis. We have previously shown that the endocannabinoid anandamide (AEA) is a lipid mediator that blocks proliferation and induces death in hepatic stellate cells (HSCs), the main fibrogenic cell type in the liver, but not in hepatocytes. However, the effects of other endocannabinoids such as N-arachidonoyl dopamine (NADA) hav...
The surface-exposed NadA adhesin produced by a subset of capsular serogroup B strains of Neisseria meningitidis is currently being considered as a vaccine candidate to prevent invasive disease caused by a hypervirulent lineage of meningococci. Levels of NadA are known to be controlled by both transcriptional regulatory factors and a component of human saliva, 4-hydroxyphenylacetic acid. Herein,...
N-arachidonoyl dopamine (NADA) is a member of the family of endocannabinoids to which several other N-acyldopamines belong as well. Their activity is mediated through various targets that include cannabinoid receptors or transient receptor potential vanilloid (TRPV)1. Synthesis and degradation of NADA are not yet fully understood. Nonetheless, there is evidence that NADA plays an important role...
Several linear fatty acid dopamides (N-acyldopamines) have been identified recently in the brain. Among them, N-arachidonoyldopamine (NADA) is an endogenous lipid mediator sharing endocannabinoid and endovanilloid biological activities. We have reported previously that NADA exerts some of its biological activities through inhibition of the NF-kappaB pathway and, because this transcription facto...
The aim of the present study was to examine whether endocannabinoids cause PPARγ-mediated vascular actions. Functional vascular studies were carried out in rat aortae. Anandamide and N-arachidonoyl-dopamine (NADA), but not palmitoylethanolamide, caused significant vasorelaxation over time (2 hours). Vasorelaxation to NADA, but not anandamide, was inhibited by CB(1) receptor antagonism (AM251, 1...
Serum samples from 31 children < or = 4 years old who were convalescing after meningococcal disease were used in a quantitative hybridization assay to establish antibody reactivity to 94 candidate meningococcal vaccine antigens. Genes encoding 22 of 23 strongly recognized proteins were found in > or = 94% of the patients' meningococcal strains, and most were also widely prevalent in Neisseria l...
N-arachidonoyl dopamine (NADA) is an endogenous ligand that activates the cannabinoid type 1 receptor and the transient receptor potential vanilloid type 1 channel. Two potential biosynthetic pathways for NADA have been proposed, though no conclusive evidence exists for either. The first is the direct conjugation of arachidonic acid with dopamine and the other is via metabolism of a putative N-...
