BACKGROUND To evaluate the prevalence and characteristics of paratracheal air cysts and their association with emphysema and gender in a general population using low-dose computed tomography scanning of the chest. MATERIALS AND METHODS We retrospectively enrolled a total of 924 patients (584 women, 340 men; mean age, 59.73 years; range, 37-89 years) who(More)
BACKGROUND AND PURPOSE Hyperintense putaminal rim (HPR) on the T2-weighted imaging, which has been observed in our daily practice while reading 3T brain images, has been described as a finding typical of multiple system atrophy (MSA). We hypothesized that the HPR sign is not an exclusive hallmark of MSA at a high magnetic field strength, but rather may be a(More)
PURPOSE In this study, we have examined the antitumor effects of chloroform extract of Angelica sinensis (AS-C), a traditional Chinese medicine, on glioblastoma multiforme (GBM) brain tumors in vitro and in vivo. EXPERIMENTAL DESIGN In vitro, GBM cells were treated with AS-C, and the cell proliferation, changes in distributions of cell cycle, and(More)
In our previous study, intracerebral implantation of peripheral blood stem cells (PBSCs) improved functional outcome in rats with chronic cerebral infarction. Based on this finding, a randomized, single blind controlled study was conducted in 30 patients [PBSC group (n = 15) and control group (n = 15)] with middle cerebral artery infarction confirmed on a(More)
BACKGROUND Because granulocyte colony-stimulating factor (G-CSF) has anti-inflammatory and neuroprotective properties and is known to mobilize stem cells, it may be useful in the treatment of acute ischemic stroke. We sought to examine the feasibility, safety and efficacy of using G-CSF to treat acute stroke. METHODS We conducted a randomized, blinded(More)
The naturally-occurring compound, n-butylidenephthalide (BP), which is isolated from the chloroform extract of Angelica sinensis (AS-C), has been investigated with respect to the treatment of angina. In this study, we have examined the anti-tumor effects of n-butylidenephthalide on glioblastoma multiforme (GBM) brain tumors both in vitro and in vivo. In(More)
AIM Obsessive-compulsive disorder (OCD) is a chronic disabling neuropsychiatric disorder. Current treatment modalities, such as pharmacological and behavioral methods, are sometimes unsatisfactory. The mesolimbic dopaminergic pathway is supposed to have a role in the pathogenesis of OCD. In this study, L-3,4-Dihydroxy-6-[F-18]fluorophenylalanine (F-18(More)
Gossypiboma is composed of non-absorbable surgical material with a cotton matrix. Gossypiboma is usually under-reported and is a severe medicolegal issue. Thus, we describe the computed tomography (CT) findings of gossypiboma in our institution. From January 2003 to June 2006, gossypibomas diagnosed in our institution and their data regarding sex, age,(More)
ProSplicer is a database of putative alternative splicing information derived from the alignment of proteins, mRNA sequences and expressed sequence tags (ESTs) against human genomic DNA sequences. Proteins, mRNA and ESTs provide valuable evidence that can reveal splice variants of genes. The alternative splicing information in the database can help users(More)
