Maternal exercise during pregnancy has been suggested to exert the beneficial effects on the brain functions of offspring. In the present study, we attempted to determine the effects of maternal treadmill running during pregnancy on short-term memory ability, hippocampal cell survival, and the expression of brain-derived neurotrophic factor (BDNF) mRNA in(More)
In the present study, the effects of acupuncture on the endurance treadmill exercise, serotonin (5-hydroxytryptamine, 5-HT) synthesis, and tryptophan hydroxylase (TPH) expression in the dorsal raphe nuclei were investigated. Acupunctural stimulation were bilaterally inserted into the locus of Zusanli in each hind leg for 20 min. Onset of exhaustion time on(More)
BACKGROUND Metabolic syndrome (MS) is associated with increased risks of diabetes and atherosclerotic cardiovascular disease. However, data on the impact of MS and its individual components on subclinical atherosclerosis (SCA) according to diabetes status are scarce. METHODS Surrogate markers of SCA, brachial-ankle pulse wave velocity (baPWV), and carotid(More)
Saturated fatty acids are known to activate macrophages and induce vascular inflammation. Although cytokines from activated macrophage influence other vascular cells, the influence of saturated fatty acids on the paracrine effect of macrophages is not fully understood yet. Here we examined the impact of palmitate on the effect of macrophages on vascular(More)
BACKGROUND AND OBJECTIVES Medical insurance claims (MIC) data are one of the largest sources of outcome data in the form of International Classification of Diseases (ICD) codes. We evaluated the validity of the ICD codes from the Korean National MIC data with respect to the outcomes from acute myocardial infarction (AMI) in the Korean Heart Study. (More)
AIMS To identify the genetic risk factors that influence the development of electrocardiographic (ECG) left ventricular hypertrophy (LVH), a major risk factor for cardiovascular (CV) morbidity and mortality. METHODS AND RESULTS We performed a genomewide association study (GWAS) of ECG-LVH, in which the community-based Korea Association REsource (KARE)(More)
PURPOSE Plasma adiponectin concentrations are inversely related with metabolic syndrome (MetS), and MetS is associated with increased risk for heart failure (HF). However, the relationship between adiponectin and MetS in HF remains undetermined. Therefore, we tested whether MetS was associated with the degree of plasma adiponectin concentrations in HF(More)
BACKGROUND Although several risk factors for stroke have been reported in patients with atrial fibrillation (AF), the relation of LV diastolic dysfunction to stroke is still uncertain in these patients. We evaluated the relationship between tissue Doppler-derived index, E/E', as well as other clinical and echocardiographic parameters and ischemic stroke by(More)
BACKGROUND Studies on factors which may predict the risk of diabetes are scarce. This prospective cohort study was conducted to determine the association between adiponectin and type 2 diabetes among Korean men and women. METHODS A total of 42,845 participants who visited one of seven health examination centers located in Seoul and Gyeonggi province,(More)
