We investigated the urinary excretion of ribonucleosides and an unidentified substance in 345 healthy probands from the age of a few weeks to 40 years. The concentration of ribonucleosides, related to the corresponding concentration of creatinine, decreases until nearly 20 years and remains constant between 20 and 40 years. The polynomial functions describing this dependency are presented. The ...

and perhaps only, country to classify pro-pofol as a controlled substance. In February 2011, the Korean Ministry of Food and Drug Safety classified propofol as a psy-chotropic drug, making it illegal to prescribe or consume other than for stipulated treatments that may need sedation, such as a gastrointestinal endoscopy [1]. In this month's Korean Journal of Anesthesiology, we learned that Kim ...

Techniques for analysis aim at diminishing the gap between users’ concepts of the problem domain of computer systems and the computers’ requirements for algorithmic and structural precision. This paper aims at improving techniques for analysis through suggesting a new type of relation between objects. We have defined a new abstraction relation called lifetime dependency: when an object (the dep...

Changes in sexual behavior have resulted in longer periods of multiple serial or concurrent relationships. This study investigated the effects of multiple heterosexual partners on mental health, specifically, whether higher numbers of partners were linked to later anxiety, depression, and substance dependency. Data from the Dunedin Multidisciplinary Health and Development Study, a prospective, ...

The purpose of the current study was to assess the rate of substance use in patients with medical diseases who were admitted to different wards at Shiraz hospitals affiliated to the Shiraz University of Medical Sciences. Data were gathered from 600 randomly selected patients by a structured interview that included DSM-IV criteria for substance dependency. The mean ages for men and women were 45...

BACKGROUND Substance use among Korean adolescents has been increasing, but little is known about the correlates of substance use in this population. Identification of the correlates is required for development of preventive approaches that aim to reduce or eliminate risk. Therefore, we examined the prevalence and correlates of substance use including psychological problems in a nationwide sampl...

BACKGROUND Recent studies have identified reinforcing properties associated with tanning and suggest a possible physiologic mechanism and addiction driving tanning behavior. OBJECTIVE This article attempts to synthesize the existing literature on tanning and addiction to investigate possible associations. METHODS We investigated a variety of substance dependence models to define what consti...

Background: Today, the society’s need to find the roots of a few thousand-year old substance abuse and the drugs addiction crisis has increased to the extent that it has become a problem within our country. The problem of substance dependence is not only about drug abuse, but it is actually the interrelationship of the person and the dependency on drugs. This study aimed to compare early malada...

Research on filler-gap dependencies has revealed that there are constraints on possible gap sites, and that real-time sentence processing is sensitive to these constraints. This work has shown that comprehenders have preferences for potential gap sites, and immediately detect when these preferences are not met. However, neither the mechanisms that select preferred gap sites nor the mechanisms u...
