This study aimed to determine the suicide mortality within 1 year after discharge from psychiatric inpatient care and identify the risk factors for suicide completion during this period. A total of 8403 patients were admitted to general hospitals in Seoul, Korea, for psychiatric disorders from January 1989 to December 2006. The suicide mortality risk of(More)
Chondrogenic differentiation and cartilage tissue formation derived from stem cells are highly dependent on both biological and mechanical factors. This study investigated whether or not fibrin-hyaluronic acid (HA) coupled with low-intensity ultrasound (LIUS), a mechanical stimulation, produces an additive or synergistic effect on the chondrogenesis of(More)
OBJECTIVES/HYPOTHESIS Treatment and management of tracheal defects remain challenging in head and neck surgery. Various reconstruction techniques have been used, with no consensus on the best approach. The purpose of this study was to explore a novel strategy to fabricate tissue-engineered trachea by using fibrin/hyaluronic acid (HA) composite gel and(More)
PURPOSE As adjuvant therapy for enhancing the effects of stimulants and thereby minimizing medication doses, we hypothesized that aerobic exercise might be an effective adjunctive therapy for enhancing the effects of methylphenidate on the clinical symptoms, cognitive function, and brain activity of adolescents with attention deficit hyperactivity disorder(More)
BACKGROUND AND OBJECTIVES Several recent studies have shown that there is an inverse relationship between plasma B-type natriuretic peptide (BNP) and body mass index (BMI) in subjects with and without heart failure. Obesity frequently coexists with diabetes, so it is important to consider the relationship between diabetes and natriuretic peptide levels. We(More)
By using the gain nonlinearity characteristics of semiconductor optical amplifier, an all-optical binary half adder at 10 Gbps is demonstrated. The half adder operates in a single mechanism, which is cross gain modulation. The half adder utilizes two logic functions of SUM and CARRY, which can be demonstrated by using XOR and AND gates, respectively. The(More)
A 12-wk experiment was conducted to examine the hematological changes, survival, and respiratory exchange in the olive flounder, Paralichthys olivaceus, during starvation. The growth, survival and respiratory exchange rates of the starved group were lower than those of the fed group during the experiment. Blood analysis, including hematocrit, hemoglobin,(More)
An adenosquamous carcinoma is a malignancy that has both glandular and squamous histologic components. Both components are malignant and have potential to metastasize. An adenosquamous carcinoma of the large bowel is rare, and its clinicopathologic behavior is not fully understood. It is reported to be more aggressive and have a worse prognosis when it is(More)
Metronidazole is a 5-nitroimidazole compound known as an antimicrobial agent widely used for the treatment of protozoal infection, anaerobic infection, Helicobacter pylori infection and hepatic encephalopathy. It may produce a number of neurologic side effects including peripheral neuropathy, seizure, encephalopathy, ataxic gait and dysarthritic speech.(More)
Nonsteroidal anti-inflammatory drugs (NSAIDs) are usually used for the treatment of inflammatory diseases. However, certain NSAIDs also have antitumor activities in various cancers, including head and neck cancer, through cyclooxygenase-dependent or independent pathways. Nonsteroidal anti-inflammatory drug-activated gene-1 (NAG-1), a TGF-β superfamily(More)
