BACKGROUND: The purpose of this study was to analyze the relationships between cardiorespiratory fitness and body mass index (BMI), metabolic syndrome risk factors, homeostasis model assessment-insulin resistance (HOMA-IR), and high sensitivity C-reactive protein (hsCRP) in male high school students in Korea. Furthermore, the effects of the cardiorespiratory fitness levels on these four factors were examined. METHODS: The level of cardiorespiratory fitness, BMI, percent body fat, waist circumference (WC), systolic blood pressure, glucose, triglycerides (TG), high-density lipoprotein-cholesterol (HDL-C), HOMA-IR, and hsCRP of 227 male high school students were measured. Analyses of multiple correlation and simple regression were applied. RESULTS: The results showed that the level of cardiorespiratory fitness correlated negatively with BMI, percent body fat, WC, TG, and HDL-C, in addition to HOMA-IR and hsCRP, and strongly influenced BMI, percent body fat, WC, TG, HDL-C, HOMA-IR, and hsCRP. Comparative analysis of our subjects showed that higher cardiorespiratory fitness levels had positive effects on BMI, metabolic syndrome risk factors, HOMA-IR, and hsCRP. CONCLUSIONS: This study found that there are close correlations between cardiorespiratory fitness and BMI, metabolic syndrome risk factors, HOMA-IR, and hsCRP. It also showed that, compared to lower levels of cardiorespiratory fitness, higher levels had beneficial effects on BMI, metabolic syndrome risk factors, diabetes, and cardiovascular disease risk factors.

OBJECTIVE: Human papillomavirus (HPV) is strongly implicated as a causative agent in the etiology of cervical cancer. Of its gene products, E6 and E7 oncoproteins play major roles by inactivation of cellular p53 and pRb tumor suppressor proteins, respectively. However, it has been recently suggested that p53 and/or pRb-independent functions of E6 and E7 are involved in cervical carcinogenesis. The purpose of this study is to identify novel a cellular target, p73, of E6 and to determine how E6 inactivates p73 function, METHODS: The interaction between E6 and p73 were identified by the yeast two-hybrid assay in vivo and the GST pull-down assay in vitro. The function of the interaction was determined by transient transfections using p21 promoter-CAT reporter plasmid. The molecular mechanism underlying the functional significance of the interaction was further assessed by in vivo and in vitro protein degradation assays, and gel mobility shift assays. RESULTS: Yeast two-hybrid and GST pull-down assays indicate a physical interaction between p73 and either HPV-16 or HPV-11 E6 proteins in vivo and in vitro, respectively. Transactivation domain (amino acid residues 1-49) is found to be absolutely required for this interaction. Transient co-expression of E6 significantly inhibits the p73-mediated activation of p21WAF1 promoter in a p53-defective C33A cell line. Using Ga14-p73 fusion protein, we demonstrate that E6 inhibition of p73 transactivation function is independent of sequence-specific DNA binding, which is confirmed by direct electrophoretic mobility shift assay. Moreover, E6 inhibits p73 function by interfering with the activity of the amino-terminal activation domain. The protein degradation assays in vivo and in vitro indicate that p73, unlike p53, is not susceptible to E6-dependent proteolysis. CONCLUSION: Throughout this study, we identified p73 as a novel cellular target of HPV-E6 protein and found that E6 binds p73 through the amino-terminal transactivation domain, and inhibits its transactivation function independent of the protein degradation and DNA binding. These overall results, consequently, suggest that in addition to the inactivation of p53, the functional interference of p73 by HPV-E6 may, at least in part, contribute to E6-mediated cellular transformation.

The use of resorbable implants has always been attractive to surgeons because there is no need to remove implant ai'ter fracture fixation. Other advantages include decreased load sharing, multi-taskirv ancl no metal toxicity. But the strength and stiffness of resorhable implants are less than those of metallic implants. Therefore, these implants are suitahle for fixation of particular fractwre sites such as cancellous bone and epiphyscs in which shear loads comprise the major strains. The purpose of this experimental study was to determine whether there are changes in mechanical properties and tissue reactions in the polylactic acid (PLA) rod hy surface moditication using plasma coating or hexafluoropropylene (CF3CF=CF2). PLA rods were inserted into the subcutaneous tissue of back and distal femur in rabbits. Rods in subcutaneous tissue were retrieved for material characterization and those in distal femur were ohtained for histologic observation at postoperative 2, 5, 12 and 16 weeks. The results were as follows; 1. The hydrophobicity of PLA surface was successfully ohtained by plasma coating of hexatluoropropylene gas. 2. Thcre is no significant change in tissue reaction. between controi and plasma coating PLA group. 3. The diametral strength and 3-points bending strength of plasma coating groups were higher than those of control group until postoperative 12 wks, but, diminished at postoperative 16 weeks. In conclusion, the plasma coating of PLA rod using fluorocarbon is a reasonable technique to incrcase the surface hydrophohicily and a promising method to delay the reduction of the strength of PLA rod. Further study on thicker plasma coating and Jong term effect including degradation, nsetaholism and excretion of cotated fluorocarhon will be needed.

PURPOSE: To investigate the effect of steroid treatment (intravenous injection, oral) in patients with non-arteritic anterior ischemic optic neuropathy (NAION). METHODS: From January, 2005 to December, 2016, 41 patients who were diagnosed with NAION and observed for more than 6 months were included in this study. The treatment was decided based on patient's choice after explaining the advantages and disadvantages of steroid therapy. The patients were divided into three groups (intravenous steroid injection, oral steroid, no treatment). Initial visual acuity, final visual acuity, degree of visual field defect, fluorescein angiography, visual evoked potential and brain magnetic resonance imaging were analyzed by chart review. RESULTS: The chief complaints of the 41 NAION patients at the first visit were decreased visual acuity (n = 24), visual field defect (n = 10), no symptoms (n = 4), diplopia (n = 2), and floaters (n = 1). The distribution of the patients according to steroid administration method was 15 patients with intravenous steroid injection, 14 patients with oral steroid and 12 patients with no treatment. The improvement in visual acuity was greatest in intravenous steroid injection (87%), oral steroid (43%) and no treatment (33%) in that order. CONCLUSIONS: In a retrospective comparison of treatment effects after explaining the advantages and disadvantages of steroid therapy in patients with NAION, the intravenous steroid injection group showed 87% improvement in visual acuity and an odds ratio of 5.5 (95% confidence interval [CI] 1.05–28.88, p-value 0.04), while the oral steroid group showed 43% improvement and an odds ratio of 1.5 (95% CI 0.30–7.43, p-value 0.62). The steroid treatment group showed better visual acuity improvement than the no treatment group, and the intravenous steroid injection group showed 5.5 times greater improvement in visual acuity compared to the no treatment group.

PURPOSE: To report a case of posterior ischemic optic neuropathy accompanied by carotid artery plaque in a patient with retrobulbar optic neuritis. CASE SUMMARY: A 48-year-old man visited our clinic complaining of headache, decreasing visual acuity and defect of inferior visual field in his left eye for 3 days. The best corrected visual acuity was 1.0 in the right eye and 0.1 in the left eye. The anterior segment state, intraocular pressure, fundus examination and optical coherence tomography were normal in both eyes. Relative afferent pupillary defect, color vision deficiency and total scotoma were observed in his left eye. The results of the laboratory test and brain magnetic resonance imaging were normal. He was discharged from the hospital after 3 days of systemic steroid treatment on the basis of retrobulbar optic neuritis. A week later, fluorescent angiography and carotid ultrasonography were performed because of his history memory loss and left upper limb weakness before admission. A focal filling defect of the peripapillary area was found on fluorescent angiography. A plaque with a thickness of 1.9 mm and a length of 1.4 cm was found on carotid ultrasonography. After 6 months, the best corrected visual acuity was 0.4 in the left eye and the visual field showed a partially improved defect. CONCLUSIONS: Fluorescent angiography is recommended for potential posterior ischemic optic neuropathy in patients with retrobulbar optic neuritis, even though it is rare. Carotid ultrasonography is useful in finding atherosclerosis to prevent stroke or cardiovascular disease if ischemic cause is suspected on fluorescent angiography.
