1. LET THE GAMES BEGIN: THE OPENING CEREMONIES. For those who think globally, "down under" may provoke thoughts of Australia-the home of the 2000 Olympic Games. For those who think rationally, "down under" may provoke thoughts of denominators of fractions. In this paper, we hope to provoke both. In basic diophantine approximation, the name of the game is to tackle the following: How close do in...

The aim of this study was to assess the usefulness of virtual environments representing situations that are emotionally significant to subjects with eating disorders (ED). These environments may be applied with both evaluative and therapeutic aims and in simulation procedures to carry out a range of experimental studies. This paper is part of a wider research project analyzing the influence of ...

: The most common cause of acquired long QT syndrome in patients without physiological and structural cardiovascular disease is the use medications. Chronic high-dose methadone usage can prolongation interval that may provoke life-threatening arrhythmia Torsades de Pointes. In this study, we present a 41-year-old man with chronic who developed Pointes triggered by short-coupled premature ventri...

Immunological methods allow of a more precise discrimination between similar proteins or high-molecular-weight carbohydrates than any chemical or physical method; but they have in practice been little used in analysis. There are a number of reasons for this: only substances which are antigenic can be identified; the major component of a mixture may provoke less antibody than a contaminant, or n...

High levels of reactive oxygen species (ROS) are observed in chronic human diseases such as neurodegeneration, Crohn's disease, and cancer. In addition to the presence of oxidative stress, these diseases are also characterized by deregulated inflammatory responses, including but not limited to proinflammatory cytokine production. New work exploring the mechanisms linking ROS and inflammation fi...

Metformin is an antihyperglycemic agent commonly used in diabetic patients. It is very effective and is able to reduce the plasma glucose and HbA1C. However, in some patients, specially those with comorbidities, metformin can provoke severe lactic acidosis with high morbimortality. Treatment of the lactic acidosis induced by metformin is based on the use of supportive general measures; in sever...

www.endojournal.com.ar 540 Dental pulp is a highly vascularized and innervated tissue. The neural component of the pulp tissue consists of motor and sensory nerve fibers, the latter coming from the cranial nerve V; all stimuli that provoke these fibers will result in a painful sensation. Dental pulp tissue is not the only tissue with this characteristic. The eye cornea and the tympanic membrane...

High Cd concentrations and excess Zn often interfere with mineral nutrients uptake by ion competition as well as affecting membrane permeability (Siedleska, 1995). The induced changes in cell ion homeostasis generally provoke different physiological disorders resulting finally in plant growth inhibition. It has been suggested that Cd and Zn have a similar mode of toxic action (Breckle, 1991; Cl...

We anticipate a potential phishing strategy by obfuscation of Web links using Internationalized Resource Identifier (IRI). In the IRI scheme, the glyphs of many characters look very similar while their Unicodes are different. Hence, certain different IRIs may show high similarity. The potential phishing attacks based on this strategy are very likely to happen in the near future with the boostin...
