It remains unknown whether increased risk with low levels of vitamin D is present for colon and/or rectal cancer. To investigate the association between circulating vitamin D levels and colon and rectal cancer, we examined the associations between plasma levels of 25-hydroxyvitamin D [25(OH)D] and 1,25-dihydroxyvitamin D [1,25(OH)2D] and colon and rectal(More)
PURPOSE Microglia in the central nervous system display a marked structural dynamism in their processes in the resting state. This dynamic behavior, which may play a constitutive surveying role in the uninjured neural parenchyma, is also highly responsive to tissue injury. The role of CX3CR1, a chemokine receptor expressed in microglia, in regulating(More)
BACKGROUND Fruits and vegetables rich in antioxidants have been proposed to reduce the risk of renal cell cancer. However, few prospective studies have examined the intakes of fruits, vegetables, and antioxidant vitamins in relation to the risk of renal cell cancer. METHODS We prospectively examined the associations between the intakes of fruits,(More)
STUDY DESIGN A retrospective study. PURPOSE To comparatively investigated the rate of the adjacent segment degeneration and the clinical outcomes in patients with spondylolytic spondylolisthesis, spinal stenosis or degenerative spondylolisthesis. OVERVIEW OF LITERATURE There have been few studies reported on the adjacent segment degeneration following(More)
Colistimethate sodium (CMS) was recently re-introduced into clinical practice as a last resort for the treatment of nosocomial infections caused by multiresistant bacteria. This retrospective cohort study was designed to identify predictors of acute kidney injury (AKI) associated with intravenous (i.v.) CMS treatment. From March 2007 to July 2008, 71 adult(More)
BACKGROUND Prophylaxis against contrast-induced acute kidney injury (AKI) in hospitalized patients is underused. We evaluated the impact of a computerized alert program for contrast-induced AKI for hospitalized patients undergoing contrast-enhanced computed tomography (CT). STUDY DESIGN Quality improvement report. SETTING & PARTICIPANTS 463 adult(More)
BACKGROUND Inflammatory mechanisms may play an important role in the pathogenesis of cisplatin nephrotoxicity. Agonists of the peroxisome proliferator-activated receptor-gamma (PPARgamma), such as rosiglitazone, have been recently demonstrated to regulate inflammation by modulating the production of inflammatory mediators and adhesion molecules. The purpose(More)
A bacterial strain, Y8(T), capable of oxidizing carbon monoxide, was isolated from a soil sample collected from a roadside in Seoul, Korea. On the basis of 16S rRNA gene sequence similarity analyses, strain Y8(T) was shown to belong to the genus Pseudonocardia and was related most closely to the type strain of Pseudonocardia alni (99.6 % similarity). The(More)
BACKGROUND Experimental and observational studies have suggested that folate may play dual roles in colorectal cancer risk depending on the timing and dose. OBJECTIVE We examined the latency between folate intake and the incidence of colorectal cancer. DESIGN We prospectively examined associations between folate intake assessed every 2 to 4 y by using(More)
Fruit and vegetable consumption has been hypothesized to reduce the risk of renal cell cancer. We conducted a pooled analysis of 13 prospective studies, including 1,478 incident cases of renal cell cancer (709 women and 769 men) among 530,469 women and 244,483 men followed for up to 7 to 20 years. Participants completed a validated food-frequency(More)
