Cisapride, a substituted piperidinyl benzamide that is chemically related to metoclopramide, is a prokinetic agent that facilitates motility of the gastrointestinal tract (1). The mechanism by which cisapride exerts its actions is not clear. It enhances acetylcholine release in the myenteric plexus of the gut, and evidence exists that it has an agonistic(More)
The Neurexin 3 gene (NRXN3) has been associated with dependence on various addictive substances, as well as with the degree of smoking in schizophrenic patients and impulsivity among tobacco abusers. To further evaluate the role of NRXN3 in nicotine addiction, we analyzed single nucleotide polymorphisms (SNPs) and a copy number variant (CNV) within the(More)
The cholera epidemic in South America has reinforced the need for safe and effective oral vaccines. In a randomised, double-blind, placebo-controlled efficacy trial among 1563 Peruvian military recruits we have investigated the protective efficacy of an oral inactivated whole-cell/recombinant-B-subunit (WC/rBS) cholera vaccine. Participants were given two(More)
BACKGROUND Epidemiological evidence suggests a cardioprotective role of α-linolenic acid (ALA), a plant-derived ω-3 fatty acid. It is unclear whether ALA is beneficial in a background of high marine ω-3 fatty acids (long-chain n-3 polyunsaturated fatty acids) intake. In persons at high cardiovascular risk from Spain, a country in which fish consumption is(More)
We report a patient who presented to the ENT service complaining of nasal obstruction, exophthalmos, edema and ipsilateral facial congestion. Imaging studies revealed an aggressive noncalcified solid mass centered in the left nasoethmoidal region and heterogeneous avid enhancement following contrast media injection. Subsequently, a biopsy confirmed the(More)
In 2000, the circulation of indigenous measles was interrupted in Catalonia as a result of the activities of the elimination programme introduced in 1991. However, various transmission chains occurred in the indigenous population after the introduction of an imported case, and this caused a total change in the existing situation of elimination. The(More)
OBJECTIVE To determine the incidence of adverse effects of antithrombotic drugs (platelet anti-aggregants and anticoagulants) in patients with transient ischemic attacks (TIA) and mild ischemic strokes (IL). PATIENTS AND METHODS Clinical follow-up data on the patients with TIA and IL included in a community-based observational study undertaken in the(More)
