BACKGROUND Musical abilities such as recognising music and singing performance serve as means for communication and are instruments in sexual selection. Specific regions of the brain have been found to be activated by musical stimuli, but these have rarely been extended to the discovery of genes and molecules associated with musical ability.

In order to determine whether Agent Orange exposure was associated with increased frequency of medical problems, we conducted a cross-sectional epidemiologic study of Korean veterans during 1995-1996. 1,224 Vietnam and 154 non-Vietnam veterans were included in the study. Exposure to Agent Orange was assessed by structured in-depth interview on the(More)
To evaluate the prevalence and risk factors of Clonorchis sinensis infection, an epidemiologic survey was performed (3,169 residents; age range: 30-87 years; mean age = 59; 1,973 women) in three areas with different mortality rates of cholangiocarcinoma. C. sinensis prevalence was 2.1% in Chuncheon, 7.8% in Chungju, and 31.3% in Haman, where(More)
Debate continues as to whether low blood lead level, even below 5 microg/dl, impairs neurodevelopmental function in children. This study assessed the association between neurodevelopmental performance and lead exposure below 5 microg/dl in Korean children. Data were collected from 61 children, aged 7-16 years with a mean blood lead level of 2.9 microg/dl,(More)
OBJECTIVE . This study examined the differential impact of social roles and socioeconomic resources on the mental health of Korean men and women aged 65 years or older. METHODS The study sample was a weighted population of 930 people (905 survey samples) aged 65 years or older who had responded to the health behavior survey of the 2001 Korean National(More)
BACKGROUND Suicide rates have recently been decreasing on average among OECD countries, but increasing trends have been detected in South Korea, particularly since the 1997 economic crisis. There have been no detailed analyses about the changes of the suicide rates over time periods in Korea. We examined trends in both absolute and proportional suicide(More)
BACKGROUND AND AIM The prevalence of gastric cancer and Helicobacter pylori infection is unacceptably high in Korea. This study was performed to evaluate the prevalence of atrophic gastritis (AG) and intestinal metaplasia (IM) and to identify their risk factors with respect to H. pylori virulence factors, and environmental and host factors, in Korean(More)
We investigated the effect of bisindolylmaleimide (I), a widely used protein kinase C (PKC) inhibitor, on the voltage-dependent K(+) (Kv) currents of rat mesenteric arterial smooth muscle cells using the whole-cell patch-clamp technique. Bisindolylmaleimide (I) reversibly and dose-dependently inhibited the Kv currents with an apparent K(d) value of(More)
INTRODUCTION The importance of managing the metabolic syndrome has been emphasized in the prevention of cardiovascular disease. Although South Koreans have a low prevalence of obesity, little information is available about the prevalence of the metabolic syndrome and its associated risk factors. METHODS Data was obtained from individuals aged 20-79 years(More)
