Since multidrug-resistant gram-negative organisms have been increasing, polymyxin E (colistin) has been reintroduced despite its nephrotoxicity. A case-control study was performed to investigate the incidence, clinical characteristics and risk factors of colistin-induced nephrotoxicity. From August 2006 to June 2008, 47 cases receiving at least one defined(More)
OBJECTIVE To determine the feasibility of the laparoscopic approach for treating suspected early-stage gallbladder carcinoma. DESIGN, SETTING, AND PATIENTS Prospective study from a university hospital. From May 10, 2004, to October 9, 2007, the laparoscopic approach was considered for treating 36 patients with suspected gallbladder carcinoma at T2 or less(More)
Obesity is known to be associated with an increased risk of gastric cardia cancer but not with noncardia cancer. In terms of gastric dysplasia, few studies have evaluated its relationship with obesity. In addition, no study on the relationship between obesity and the risk of gastric cancer has analyzed the status of Helicobacter pylori infection. A(More)
BACKGROUND The contribution of the metal components of particulate pollutants to acute respiratory effects has not been adequately evaluated. Moreover, little is known about the effects of genetic polymorphisms of xenobiotic metabolism on pulmonary function. OBJECTIVES This study was conducted to assess lung function decrement associated with metal(More)
In this study, we found that no Candida species other than C. albicans is able to form germ tubes at 39 degrees C in serum-free YEPD (1% (w/v) yeast extract, 2% (w/v) peptone and 2% (w/v) dextrose) media, which makes it easy to identify C. albicans from other Candida species. When cultivated in rabbit serum for at least 2 h at 37 degrees C, more than 60% of(More)
Although importation of asbestos to Korea has decreased, there are growing concerns of its hazardous effects. This paper describes the use and occupational exposure to asbestos, and the incidence and mortality of malignant mesotheliomas in Korea. Asbestos raw material imports from other countries peaked between 1990 and 1995, but importation of(More)
IMPORTANCE OF THE FIELD Although the solid dispersion method has been known to increase the dissolution rate of poorly water-soluble drugs by dispersing them in hydrophilic carriers, one obstacle of the solid dispersion method is its limited solubilization capacity, especially for pH-dependent soluble drugs. AREAS COVERED IN THIS REVIEW pH-modified solid(More)
Epstein-Barr virus infection in vitro immortalizes primary B cells. EBNA2 is an Epstein-Barr virus-encoded transcriptional transactivator that mimics the effects of activated Notch signaling and is essential for this proliferative response. An assay using Sindbis virus (SV) as a cell death inducer revealed that, like Notch, EBNA2 also has antiapoptotic(More)
Polycyclic aromatic hydrocarbon (PAH) exposure and oxidative stress from such and other exposures have been associated with breast cancer in some studies. To further evaluate the role of PAH metabolites and oxidative stress on the development of breast cancer, we conducted a nested case-control study in the Shanghai Women's Health Study. We measured urinary(More)
OBJECTIVE Smoking is associated with rheumatoid arthritis (RA) in individuals with the HLA-DRB1 shared epitope (SE). SE alleles have been shown to be predominantly associated with anti-cyclic citrullinated peptide (anti-CCP)-positive RA. These risk factors have not been identified for anti-CCP-negative RA. The aim of this study was to investigate whether(More)
