BACKGROUND/AIMS Recent advances in diagnostic techniques have led to the detection of an increasing number of early gastric cancers in the upper third of the stomach. The objective of this study was to determine the most appropriate surgical treatment for these cancers. METHODOLOGY The clinicopathologic characteristics of 35 patients with early gastric(More)
OBJECTIVE To identify the risk factors for pre-eclampsia in an Asian population. METHOD We conducted a retrospective cohort study involving 29375 Taiwanese women who delivered between July 1990 and September 1998, excluding pregnancies complicated by chronic hypertension or fetal malformations. RESULT Four hundred and fifteen women had pre-eclampsia(More)
The prevalence of Behcet's disease is the highest in the East Asian and the Mediterranean countries. Behcet's disease is also distributed in the Asian countries, but the nationwide survey has not been performed in Korea yet. The Korean Study Group for Behcet's Disease, founded in 1999, conducted a multicenter, retrospective survey on epidemiologic and(More)
A variety of environmental factors were identified to be associated with the risk of esophageal cancer. The variation in capacity of DNA repair might influence environmental chemical-associated carcinogenesis. We hypothesized that the polymorphic XRCC1 genes might modify cancer susceptibility of the esophagus. To investigate the effect of XRCC1 genetic(More)
The interaction of genetic and environmental factors can determine an individual's susceptibility to various cancers. We present a hospital-based case-control study, which included 90 patients of esophageal squamous-cell carcinoma (ESCC) and 254 healthy people in Taiwan, to investigate the effects of genetic polymorphisms of p53, GSTP1 and NAT2 on the risk(More)
To define the physiological role of IP(3)3-kinase(A) in vivo, we have generated a mouse strain with a null mutation of the IP(3)3-kinase(A) locus by gene targeting. Homozygous mutant mice were fully viable, fertile, apparently normal, and did not show any morphological anomaly in brain sections. In the mutant brain, the IP4 level was significantly decreased(More)
BACKGROUND Adenosine deaminase (ADA) and carcinoembryonic antigen (CEA) have been measured in pleural fluid to help distinguish malignant from benign effusions, especially in tuberculous pleurisy. We investigated ADA and CEA levels in patients with moderate to large pericardial effusions of different etiologies. METHODS AND RESULTS We performed diagnostic(More)
Streptococcus pneumoniae is a causative agent for bacterial pneumonia, otitis media, meningitis, and bacteremia. Mechanisms for acquisition of iron by this organism under low-iron conditions were investigated. Siderophore production was not detected by either chemical or biological methods. Its utilization of iron-containing compounds found in human hosts(More)
Gastrodia elata Bl. (GE) is a traditional Chinese herb that is commonly used in Chinese communities to treat convulsive disorders such as epilepsy. The purpose of the present study was to determine the anticonvulsive and free radical activities of GE in rats. In vitro studies were conducted by using brain tissue from 6 male Sprague-Dawley (SD) rats treated(More)
Expression of the bovine papillomavirus E2 regulatory protein in human cervical carcinoma cell lines repressed expression of the resident human papillomavirus E6 and E7 oncogenes and within a few days caused essentially all of the cells to synchronously display numerous phenotypic markers characteristic of cells undergoing replicative senescence.
