Resveratrol has been reported to exert anticancer activity via modulation of multiple pathways and genes. In this study, we examined the effect of resveratrol on YD-10B human oral squamous cell carcinoma cells and its molecular mechanisms of action. We found that resveratrol inhibited the proliferation of YD-10B cells in a dose- and timedependent manner. The suppressive effect of resveratrol was accompanied by a reduction in Bmi-1 gene expression.We observed that silencing the Bmi-1 gene by small interfering RNA effectively downregulated the levels of GLUT1 mRNA and protein, which were also repressed by resveratrol. Bmi-1 silencing increased the number of YD-10B cells in S-phase arrest by approximately 2.3-fold compared with the control. In conclusion, the results of the present study demonstrate, for the first time, that resveratrol suppresses Bmi-1-mediated GLUT1 expression in human oral squamous cell carcinoma cells and suggest that the specific molecular targeting of Bmi-1 and/or GLUT1 expression can be combined with a chemotherapeutic strategy to improve the response of oral cancer cells to resveratrol.

Local cutaneous reactions have been reported at injection sites of interferon therapy, but these are usually erythema or rarely induration. Skin necrosis at the injection site is rare. We describe here a patient with multiple sclerosis who presented with cutaneous necrosis at the injection sites of interferon-β. Biopsy of the necrotic lesion showed dermal vessel thrombosis and complete ischemic coagulative necrosis of epidermis and dermis.

PURPOSE: The score for neonatal acute physiology (SNAP) based on physiologic derangements, is applied to variable fields including morbidity as well as mortality estimate. We evaluate the clinical usefulness of SNAP and SNAP variants for neonatal acute severity and mortality. METHODS: Twenty-one neonates were evaluated the SNAP, SNAP-PE, SNAP-II, and SNAPPE-II, who survived more than 24 hours in Neonatal Intensive Care Unit in Department of Pediatrics, Kyunghee University from July 2003 to December 2004. A study group included 21 neonates as death group and a control group matched for gestational age and birth weight. We analyzed the differences of clinical usefulness of SNAP and SNAP variants indices between the two groups. RESULTS: 1) SNAP:The scores were ranged 2-18 (median 6.5) in survival group and 9-31 (median 13.0) in death group. 2) SNAP-PE:The scores were ranged 2-48 (median 16.5) in survival group and 23-75 (median 32.0) in death group. 3) SNAP-II:The scores were ranged 0-16 (median 10.5) in survival group and 10-62 (median 21.0) in death group. 4) SNAPPE-II:The scores were ranged 0-45 (median 24.5) in survival group and 35-109 (median 44.0) in death group. The median values were higher in those who were died:SNAP<0.05 (P-value), SNAP-PE<0.01, SNAP-II<0.01, SNAPPE-II<0.01 showing the significant differences. CONCLUSION: The study shows that SNAP and SNAP variables are useful for the evaluation of acute severity and excellent predictors of neonatal survival. They would help the management of neonatal intensive care unit.

PURPOSE: This study was intended to investigate the migrating motor complex (MMC) changes after ileal bypass in ex-vivo mouse models. METHODS: Partial (side-to-side) and total bypass (occlusion of proximal part of bypassed loop) were performed on ileums of female Institute of Cancer Research mice. After 2 and 4 weeks, the bypassed segments were harvested and MMCs were recorded at 4 different sites ex-vivo. Amplitude, duration, interval, direction of propagation, and the area under the curve (AUC) of MMCs were measured and compared to those of the controls. RESULTS: In control mice (n = 7), most MMCs propagated aborally (91.1%). After 2 weeks of partial bypass (n = 4), there was a significant decrease in both amplitude and AUC, and orally-propagating MMCs increased significantly (45%, P = 0.002). Bidirectional MMCs (originating in the bypassed loop and propagating in both directions) were also observed (10%). The amplitude of the MMCs remained decreased at 4 weeks after partial bypass (n = 4), and neither the AUC nor the direction of propagation showed significant changes compared to 2 weeks. Similarly, in the total bypass model, both the amplitude and AUC of the MMCs decreased significantly compared to controls. In contrast to partial bypass, 95% of the MMCs within the bypassed loop propagated aborally after 2 weeks (n = 6), which was similar to the control state. After 4 weeks (n = 5), however, MMCs either lost their temporal relationship or completely disappeared. CONCLUSION: The changes in propagation direction of the MMCs in the partially bypassed loop may contribute to stagnation of bowel contents and the development of blind loop syndrome.

Thyrotoxic periodic paralysis (TPP) is a transient illness characterized by muscle weakness often associated with hypokalemia during thyrotoxic state. Hypokalemia is induced by thyroid hormone excess through stimulation of Na-K ATPase which pumps extracellular potassium ions into the cell. Muscle weakness resolves when serum potassium level is corrected, but the condition may recur when there is thyrotoxicosis. TPP is most commonly reported in Asian males aged between 20 to 40 years and it is rare in children and adolescents. We report a 16-year-old patient previously diagnosed with Graves' disease who showed recurrent episodes of TPP.

Recently, water birth - labor and/or delivery under warm water - is acceptable and natural to many foreign countries as a method of gentle birth. Although some limitations after water birth were reported, a recent international conference explored many of the issuses and indicated the potential scale and the advantages for its inclusion among the options for labor and delivery under water. We experienced a case of water birth who underwent labor and delivery under water. She delivered normal healthy female baby without conventional episiotomy. No obstetrical ans fetal complications were observed during entire procedure of water birth. So, we report this case with brief review of the literatures.

Dental pulp is a highly vascularized tissue with high regenerative potential. Revascularization of severed vasculature in the tooth is required for pulp healing during avulsed tooth treatment. In this study, the relative expression of angiogenesis-related proteins was determined in human dental pulp cells using a human angiogenesis proteome profiler array. The proteome profiler array detected differentially expressed angiogenesis-related factors under conditions of hypoxia, which enhances the angiogenic potential of dental pulp cells. We confirmed that hypoxia regulates the mRNA expression of angiogenesis-related factors, including CXCL16 in dental pulp cells. Furthermore, conditioned media of hypoxic pulp cells induced tube-like structures of vascular endothelial cells, which were reduced by the neutralization of CXCL16 function. In conclusion, our data show that angiogenesis-related factors are differentially expressed by hypoxia in dental pulp cells and suggest that CXCL16 may involve in the revascularization of hypoxic dental pulp.

PURPOSE: To analyze the correlation between serum alanine aminotransferase (ALT) and obesity indices including body mass index (BMI), body fat percentage (BFP), total fat mass (FM), truncal fat mass (TFM), waist circumference (WC), and waist-to-height ratio (WHtR) in Korean adolescents. METHODS: This was a cross-sectional study based on data derived from the 2010-2011 Korean National Health and Nutrition Examination Surveys (KNHANES). Subjects were Korean adolescents aged 10-18 years (871 total; 475 boys and 396 girls) who participated in KNHANES. RESULTS: In both sexes, BMI, FM, TFM, WC, and WHtR were higher when ALT levels were in the 4th quartile. In boys, there was a significant positive correlation between ALT level and BMI, BFP, FM, TFM, WC, and WHtR (r=0.55, P<0.0001 for BMI; r=0.52, P<0.0001 for BFP; r=0.58, P<0.0001 for FM; r=0.61, P<0.0001 for TFM; and r=0.56, P<0.0001 for WC; r=0.62, P<0.0001 for WHtR), and the correlation coefficient was higher than that in girls. CONCLUSION: Our results suggest a significant positive association between serum ALT level and obesity indices in male adolescents.
