BACKGROUND AND PURPOSE The aim of this study was to determine the association between 25-hydroxyvitamin D (25(OH)D) and neuroimaging correlates of cerebral small vessel disease. METHODS We identified 759 consecutive patients with acute ischemic stroke or transient ischemic attack. Lacunes, white matter hyperintensity, and cerebral microbleed (CMB) were(More)
Although there is a controversy, several reports have shown that gastric cardia cancer has tended upwards in recent years. The aim of this study was to investigate the changing trend of stomach cancer according to the location of cancer and histologic type in Korea, where is known to be one of the most prevalent areas for gastric cancer. All the patients(More)
OBJECTIVES Reportedly, hippocampal neuronal degeneration by kainic acid (KA)-induced seizures in rats <14 days old was enhanced by lipopolysaccharide (LPS). This study was to test the hypothesis that cytokines such as interleukin (IL)-1β, IL-6 and tumor necrosis factor-α are associated with aggravated neuronal damage. MATERIALS AND METHODS Sixty male(More)
BACKGROUND Low 25-hydroxyvitamin D (25(OH)D) concentrations have been shown to predict risk of cardiovascular disease and all-cause mortality. Although the prevalence of 25(OH)D deficiency is high in patients with acute stroke, the prognostic value of 25(OH)D in stroke has not been clearly established. The purpose of this study was to determine whether the(More)
BACKGROUND/AIMS Brachial-ankle pulse wave velocity (baPWV) is a marker of vascular stiffness and is reported to be associated with diabetic neuropathy; however, the relationship between baPWV and nerve conduction study (NCS) has yet to be examined. METHODS Between January 2006 and December 2008, we investigated this relationship in diabetic patients. To(More)
BACKGROUND Pathologic investigations showed that lacunar infarction could develop in the deep cerebellar region. However, the etiology of small deep cerebellar ischemic lesions (SDCI) has not been adequately studied. The aim of this study was to investigate the relationship between SDCI and small-vessel disease. METHODS We studied 100 consecutive patients(More)
BACKGROUND It is difficult to clarify whether small deep infarction is caused by cardioembolism or intrinsic small vessel disease in patients with atrial fibrillation (AF). The purpose of this study was to determine whether preexisting small vessel disease would differ according to the presenting infarct pattern and to determine the factors associated with(More)
In this study, various fatty acids of 18 and 22 carbons were used as substrates to produce sophorolipids in Candida bombicola ATCC 22214. Methyl esterification of erucic acid and C22-enriched rapeseed oil generated mainly acidic sophorolipids with different degrees of saturation in the fatty acid chain, which was demonstrated by structural analysis using(More)
BACKGROUND AND AIMS Leukoaraiosis (LA) is associated with aging and vascular risk factors, and is a risk factor of intracerebral hemorrhage (ICH) after treatment with warfarin or thrombolytic treatment for ischemic stroke. In this study, we sought to examine whether LA is a predictor of outcome after spontaneous ICH. METHODS We retrospectively analyzed(More)
Gastritis cystica profunda is usually characterized by hyperplastic and cystic dilatation of pseudopyloric gland with submucosal invasion. These lesions possess malignant histologic features as metaplastic and even dysplastic alteration can be observed, however they usually exhibit benign behavior. Macroscopically, gastritis cystica profunda may present as(More)
