  • Sensitising cancer cells and at the same time desensitizing normal cells is a double task in cancer management. Agents which can combat the debilitating side effects of cancer therapeutics and simultaneously synergize with anticancer agents in specifically targeting cancer cells are needed. Selenium, a proven anticarcinogen, gains due importance in terms of its efficacy to combat the side effects of cancer therapy. This study is a comparative analysis of the chemoprotective effects of selenium compounds, methyl selenol (generated from organic selenomethionine (5mmol/L ; METase 40U/L)) and sodium selenite (inorganic form)($30{\mu}M$) in peripheral blood human lymphocytes exposed to cisplatin and mitomycin. Biochemical alterations occurring in many cells during apoptosis include loss of plasma membrane phospholipid asymmetry, DNA fragmentation, and activation of caspase-3. The present study demonstrated that the selenium metabolite and selenite are efficient in protecting lymphocytes undergoing DNA damage and exerted their activity by reducing caspase 3 expression. Interestingly organic methylselenol (MeSe) was found to offer more protective effects compared to inorganic selenite (SeL), by reducing the induction of apoptosis by the cytotoxic agents. This suggests that MeSe and to a lesser extent selenite might have potential for assessment in clinical trials and could be considered as strong candidates in pharmacogenomics or in the nutriprotective arena.

  • Efficacy and in vivo bioassay of recombinant human erythropoietin (rh-EPO, DWP413) was investigated. Efficacy studies on erythropoiesis were conducted in normal, cisplatin-induced anemic rats and acute hemorrhage - induced anemic rats. Animals were treated intravenously with DWP413 for 5 days, the changes in the number of red blood cells (RBC), hematocrit value (Hct), hemoglobin concentration (Hb) and reticulocyte were examined. In normal rats, at the doses of 50, 250, and 1250 IU/kg/day, in cisplatin-induced anemic rats, at the doses of 50, 100 and 200 IU/kg/day, RBC, Hb, Hct and reticulocyte were increased dose-depen-dently. And in acute hemorrhage-induced anemic rats, DWP413 (150, 450 and 1350 IU/kg/day) significantly increased RBC, Hb, Hct and reticulocytes. In histopathological findings of kidney, cisplatin alone treated rats expressed severe glomerulus and tubular damage. But in the DWP413 treated rats after cisplatin treatment, these were not remarkable compared to cisplatin alone treated rats. In vivo bioassay, DWP413 had 102.43% of bioactivity compared to erythropoietin BRP(Biological Reference Product, European Directorate for the Quality of Medicines). These results suggest that DWP413 might be useful for the therapy of anemia induce by renal failure and acute blood loss.

  • In this study, structural vulnerability of reinforced concrete moment resisting frames (RC-MRFs) by considering the Iran-specific characteristics is investigated to manage the earthquake risk in terms of multicomponent seismic excitations. Low and medium rise RC-MRFs, which constitute approximately 80-90% of the total buildings stock in Iran, are focused in this fragility-based assessment. The seismic design of 3-12 story RC-MRFs are carried out according to the Iranian Code of Practice for Seismic Resistant Design of Buildings (Standard No. 2800), and the analytical models are formed accordingly in open source nonlinear platforms. Frame structures are categorized in three subclasses according to the specific characteristics of construction practice and the observed seismic performance after major earthquakes in Iran. Both far and near fields' ground motions have been considered in the fragility estimation. An optimal intensity measure (IM) called Sa, avg and beta probability distribution were used to obtain reliable fragility-based database for earthquake damage and loss estimation of RC buildings stock in urban areas of Iran. Nonlinear incremental dynamic analyses by means of lumped-parameter based structural models have been simulated and performed to extract the fragility curves. Approximate confidence bounds are developed to represent the epistemic uncertainties inherent in the fragility estimations. Consequently, it's shown that including vertical ground motion in the analysis is highly recommended for reliable seismic assessment of RC buildings.

  • This study has been carried out to investigate the cause and originative mechanism of vertigo by referring to 46 literatures. The results were as follows; 1. The 1st factors causing vertigo are exuberance of fire in the Liver (肝火偏亢). and ascending of Yang of Wind (風陽升動) resulting from thought excess (思慮太過) and melancholy (憂鬱). 2. The 2nd factors causing vertigo is a malnurtrient of the brain resulting from dispersion of the Liver function (肝血虛) and failure in ascending of the Clear Yang (淸陽不升) due to hemorrhage and so on. 3. The 3rd factors causing vertigo are failure in ascending to the Brain and deficiency of blood of the Liver (肝血虛) resulting from the injury of the essence of the Kidney (肝精虧損). 4. The 4th factors causing vertigo is a ascending of exogenous pathogenic factors (外邪) to the Brain on deficiency state. 5. The 1st factors causing vertigo are Stagnatum of clear Yang (淸陽不振) and pershing of Yang (亡陽) resulting from loss of water and damage of active thin body fluid (津氣虧損). 6. The obesity is beonged to excessiveness Symptom-Complex (實證) and the thin to deficiency Symptom-complex (虛證). 7. The vertigo is connective with the Live (肝), Spleen (脾) and the Kidney (腎), but among those, most intimative viscera is the Liver (肝).

  • Explosions and fires on offshore drilling units and process plants, which cause loss of life and environmental damage, have been studied extensively. However, research on drilling units increased only after the 2010 Deepwater Horizon accident in the Gulf of Mexico. A major reason for explosions and fires on a drilling unit is blowout, which is caused by a failure to control the high temperatures and pressures upstream of the offshore underwater well. The area susceptible to explosion and fire due to blowout is the drill floor, which supports the main drilling system. Structural instability and collapse of the drill floor can threaten the structural integrity of the entire unit. This study simulates the behavior of fire subsequent to blowout and assesses the thermal load. A heat transfer structure analysis of the drill floor was carried out using the assessed thermal load, and the risk was noted. In order to maintain the structural integrity of the drill floor, passive fire protection of certain areas was recommended.

  • The piercing is increasing in western culture, and has also become gradually popular among Korean teenagers recently However, the accident hap-pens sometimes such as loss of a bar into the tongue or mouth floor during the procedure. Because of the rare cases, few treatment of choices can be made when a bar is lost inside the mouth floor. In this case, the bar was removed under fluoroscope, without giving significant damage to the adjacent structure. 18 years old female patient visited the emergency room in our hospital. She attempted to pierce her tongue herself and could not find the bar which was lost in the mouth floor. The radiographs revealed that the needle was somewhere inside the mouth floor, but if incision were to be made it would be too deep to find the bar. The bar was removed through fluoroscope easily. Primary closure was done by 5-0 Vicryl and stitch-off was done 1 week later. The patient didn't have any speech problems and complications.

  • There is a need to define the concept of suffering more appropriate in the context of Korean culture. This research is an attempt to reanalyze the concept of suffering by applying Walker & Avant's process of concept analysis. The steps of concept analysis are : 1. Select a concept. 2. Determine the aims or purpose of the analysis. 3. Identify all uses of the concept that you can discover. 4. Determine the defining attributes. 5. Construct model, contrary, borderline, related and invented cases. 6. Identify antecedents and consequences. 7. Define empirical referents. The concept of suffering can be defined as follows: Suffering is a fundamental and inevitable experience of all human beings. When each individual experiences loss, damage and pain which threaten one's personal integrity, suffering is perceived differently among each individual depending on their personal inner factors, one's significant others, exterior circumstances and stimuli, and the ultimate meaning of life. Suffering brings severe and unendurable distress which accompany despair, powerlessness, anxiety, bitterness, fear, anguish, guilt, depression, withdrawal and anger. The attributes of suffering were analyzed. Model case, contrary case, borderline case, related case, and invented case were described. Antecedents, consequences and empirical referents were explored. This concept analysis provides data for new insights of suffering. These findings suggests that appropriate nursing interventions aimed at relieving suffering of patients need to be developed and implemented more widely.

  • This paper intends to describe the liability regime of the air carrier under the Montreal Convention of 1999 for the international cargo, comparing to those of the existing Warsaw Convention system. Also this paper deals with main issues of the Montreal Convention which are relevant for the carrier's liability in the carriage by air of cargo. The Warsaw Convention was adopted in 1929 and modified successively in 1955, 1961, 1971, 1975, and 1999. The Montreal Convention of 1999 modernized and consolidated the Warsaw Convention and related instruments. International air carrier is liable by application of principle of strict liability as stated in the Montreal Convention : The carrier is liable for the destruction or loss of, or damage to cargo and delay during the carriage by air, and the carrier's liability is limited to a sum of 17 Special Drawing Rights per kilogramme. However, the Montreal Convention has main outstanding issues with respect to the liability of the air carrier : potential conflicts between the Montreal Convention and the Warsaw Convention, the amounts of limits of the carrier's liability, the duration of the carrier's liability, the exessive litigation, and the aviation insurance. Therefore, the conditions and limits of the carrier's liability under the Montreal Convention should be readjusted and regulated in detail.

  • Iatrogenic damage of the rotator cuff followed by postoperative shoulder function loss is a potential complication after antegrade intramedullary nailing (AIN) for a humeral fracture. The authors present a case of arthroscopic rotator cuff repair and subacromial decompression of a non-healed rotator cuff tendon (mainly supraspinatus) and secondary impingement syndrome caused either by the tear or a proud nail after AIN for a mid-shaft humeral fracture. At presentation, the patient complained of right shoulder pain and 'snapping', especially during forward elevation and abduction of the shoulder, of 4 years duration. Right shoulder pain started sometime after pain due to the humeral shaft fracture, operation had subsided, and persisted after nail removal. Arthroscopic findings showed a longitudinal rotator cuff tear at the nail entry point that had not healed and severe fibrous hypertrophy on the acromion underspace, which is a unique finding since most longitudinal splits of tendon fibers are more likely to heal than conventional rotator cuff tears detached from bone. The torn rotator cuff was repaired after debridement and placing side-to-side sutures. At his 34-month follow-up after rotator cuff repair, the patient showed complete recovery and had excellent clinical scores.

  • Ninety-two isolates of Fusarium species were obtained from Chinese corn samples. The predominant Fusarium species isolated from corn seeds were F. moniliforme, F. proliferatum, F. oxysporum and F. subglutinans, and all 13 species were identified. Each isolate was grown on autoclaved wheat grains and wheat cultures were fed by twenty-one-day-old female rats for the toxicity test. Twenty-six out of 92 isolates caused the death accompanying feed refusal, severe weight loss, liver damage, and hemorrhages in the stomach and intestines. Of the toxigenic isolates, 17 isolates of F. moniliforme, 4 of F. oxysporum, 3 of F. proliferatum, and one of each F. sporotrichioides and unknown species were lethal to rats. The analyses of fumonisin B1 production of the 26 toxigenic Fusarium isolates were carried out by thin layer chromatography and high-performance liquid chromatography, and fumonisin B1 was confirmed by mass spectrometry. Fumonisin B1 was produced in wheat culture at levels ranging from 280 $\mu\textrm{g}$/g to 3,952 $\mu\textrm{g}$/g by all of toxigenic F. moniliforme and F. proliferatum, but by none of the other toxigenic Fusarium species. The present results suggest the high possibility of natural occurrence of fumonisin B1 in corn samples imported from China.
