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)
Adefovir dipivoxyl (ADV) effectively suppresses hepatitis B virus (HBV) replication but exhibits nephrotoxicity with severe hypophosphatemia when administered at a high dosage. This is the first report of severe hypophosphatemic osteomalacia induced by ADV at 10 mg/day. A 42-year-old man with HBV-related chronic liver disease presented with generalized bone(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)
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)
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)
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)
Microtubules are essential cytoskeletal components with a central role in mitosis and have been particularly useful as a cancer chemotherapy target. We synthesized a small molecule derivative of a symmetrical 1,3-phenyl bis-thiourea, (1,1'-[1,3-phenylene]bis[3-(3,5-dimethylphenyl)thiourea], named "41J"), and identified a potent effect of the compound on(More)
Osteogenesis Imperfecta (OI) is a human syndrome characterized by exquisitely fragile bones due to osteoporosis. The majority of autosomal dominant OI cases result from point or splice site mutations in the type I collagen genes, which are thought to lead to aberrant osteoid within developing bones. OI also occurs in humans with homozygous mutations in(More)
The purpose of this study is to demonstrate scarless vocal fold (VF) regeneration by using a composite gel composed of small intestine submucosa (SIS) and mesenchymal stem cells (MSCs). A scar was made with an electrocoagulator on both VFs in 24 rabbits, followed by injection of either MSCs, SIS, or MSCs-SIS composite gel in the right side VF, while the(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)
