The basic graph layout technique, one of many visualization techniques, deals with the problem of positioning vertices in a way to maximize some measure of desirability in a graph. The technique is becoming critically important for further development of the field of systems biology. However, applying the appropriate automatic graph layout techniques to the genomic scale flow of metabolism requires an understanding of the characteristics and patterns of duplicate and shared vertices, which is crucial for bioinformatics software developers. In this paper, we provide the results of parsing KEGG XML files from a graph-theoretical perspective, for future research in the area of automatic layout techniques in biological pathway domains.

BACKGROUND: We evaluated the clinical and radiological results of one-stage correction for cerebral palsy patients. METHODS: We reviewed clinical outcomes and radiologic indices of 32 dysplastic hips in 23 children with cerebral palsy (13 males, 10 females; mean age, 8.6 years). Ten hips had dislocation, while 22 had subluxation. Preoperative Gross Motor Function Classification System (GMFCS) scores of the patients were as follows; level V (13 patients), level IV (9), and level III (1). Acetabular deficiency was anterior in 5 hips, superolateral in 7, posterior in 11 and mixed in 9, according to 3 dimensional computed tomography. The combined surgery included open reduction of the femoral head, release of contracted muscles, femoral shortening varus derotation osteotomy and the modified Dega osteotomy. Hip range of motion, GMFCS level, acetabular index, center-edge angle and migration percentage were measured before and after surgery. The mean follow-up period was 28.1 months. RESULTS: Hip abduction (median, 40degrees), sitting comfort and GMFCS level were improved after surgery, and pain was decreased. There were two cases of femoral head avascular necrosis, but no infection, nonunion, resubluxation or redislocation. All radiologic indices showed improvement after surgery. CONCLUSIONS: A single event multilevel surgery including soft tissue, pelvic and femoral side correction is effective in treating spastic dislocation of the hip in cerebral palsy.

The antisynthetase syndrome is characterized by anti-Jo-1 antibody production, interstitial lung disease, inflammatory muscle disease, and, in many cases, fever, polyarthritis, Raynaud's phenomenon, and mechanic's hands. Joint signs and symptoms occur in up to 90% of patients with antisynthetase syndrome, occasionally as the initial manifestations. Although visual inspection of the hands shows changes that are highly suggestive of rheumatoid arthritis, notable differences exist. Antisynthetase syndrome is a predominantly nonerosive arthropathy with subluxations of the distal interphalangeal joints. It manifests as overlap syndrome with other connective tissue diseases. However, overlap syndrome of antisynthetase syndrome and rheumatoid arthritis is rare. We treated a 51-year-old male patient with overlap syndrome of antisynthetase syndrome and rheumatoid arthritis, and report the case with a review of the literature.

The long arm duplication of chromosome 3 was reported for the first time in 1966 by Falek et al., and Hirschhorn et al. came to identify the duplication of 3q21--> qter region in 1973. In most cases of duplication 3q syndrome patients, pure duplication of 3qter is believed to be rare and is often reported accompanied with deletion of another segment of the chromosome. Approximately 75 percent of parents of the patient in the meantime have been demonstrated to have unbalanced translocations or inversions of the chromosome. Partial deletion of the distal part of the short arm of chromosome 3 was first reported by Verjaal and De Nef in 1978 and terminal deletion of chromosome 3 (3p25- qter) has been observed in most cases. In karyotyping of chromosomes of immature infants showing the manifestations of flat occiputs, low set ears, hypertelorism, broad nasal roots, thin lips, web necks, hypotonia, hypertrichosis skin, cryptorchidism etc, we experienced a case diagnosed as 46, XY, rec (3) dup (3) (q21) del (3) (p25) inv (3) (p25q21).

PURPOSE: The purpose of this study was to identify the relationships between life style, menstrual attitude and premenstrual syndrome in nursing students. METHODS: The study participants were 246 nursing students of a university in Gyeunggi province. Data were collected by a self-administered questionnaire from May to June, 2012. Collected data were analyzed using the SPSS/WIN 20.0 program with descriptive statistics, Pearson correlation coefficient, t-test, one-way ANOVA and Scheffe test. RESULTS: Students who had undesirable alcohol habits (r=.15, p=.020) and negative menstrual attitude (r=.17, p=.009) experienced more a severe premenstrual syndrome (PMS). Students with dysmenorrhea had more severe PMS (F=12.41, p<.001) and a negative menstrual attitude (F=6.18, p<.001). CONCLUSION: These finding suggest that PMS would be alleviated by nursing interventions to improve alcohol habits and decrease negative menstrual attitudes, and nursing interventions for dysmenorrhea would be helpful in PMS management in nursing students. Further studies on the development of nursing interventions related to these factors are needed for PMS management.

PURPOSE: We observed new bone formation following the transplantation of allogenic periosteum-derived stem cells and different sizes of hydroxyapatite (HA) scaffold materials into rabbit long-bone defects. MATERIALS AND METHODS: Thirty-two white rabbits were grouped according to the material transplanted into their tibial bone defects: group 1 (microscale HA only); group 2 (nanoscale HA only); group 3 (microscale HA plus stem cells); and group 4 (nanoscale HA plus stem cells). Viscosity was controlled by the relative amounts of HA and agar. After surgery, radiologic, microscopic, and biochemical observations were performed weekly for 8 weeks. RESULTS: Nanoscale HA (groups 2 and 4) provided better bone formation than microscale HA (groups 1 and 3). The rabbits that had been transplanted with nanoscale HA plus stem cells (group 4) had more homogeneous bone formation during the natural repair process than the other groups. CONCLUSION: Further study is required using nanoscale HA plus organic substance and stem cells, which are more similar to human bone structure, for better bone formation.

The authors attempted a pdssibility of unifcation in the educational curricula of both Oriental and Western medical schools for the unification of two medicines . Historically the two medicines were originated from the most primitive state like intinctive method and we can say two medicines were entirely same. However after abrupt and current development of science in 19 century by discovery of microscope and bacteria as well as cells changed medicine into recent unbelievable current medicine from old ancient style medicine like Chinese Medicine which was just the remnant old medicine. The unification of educational curricular is thought to be possible to combine each other by technical adjustment from mutual understanding and cooperations for the most high quality of people's lives. There were good equality to partial corrrespondances between two educational curricular around 90 % at two pre- and schools from the study to analyse. The combined medicine is thought to be more efficient to the diagnosis and treatment of patients because of the effectiveness of Oriental medicine in a certain disease conditions like chronic illness by acupuncture as a alternative medicine or herbs.

BACKGROUND: Coronary artery disease(CAD) has been related to a number of factors, including diabetes, smoking,hypertension, blood lipids, and family history of CAD. However, a few studies have examined the correlation between these factors and severity of CAD. In the present study, we aimed to define the correlation between risk factors and the severity of CAD. METHODS: The study population was 309 consecutive patients who underwent coronary angiography in Kang Nam St. Marys hospital between Mar. 1992 and Aug. 1994. We analyzed risk factors of CA ; age, total cholesterol(TC), triglyceride, high density lipoprotein cholesterol(HDL-C), low density lipoprotein cholesterol cholesterol(LDL-C), the ratio of TC to HDL-C, Lp(a), uric acid, fibrinogen, diabetes, hypertension, smoking, and family history of CAD. All films were reviewed without specific knowledge of blood laboratory results. Significant occlusive disease was defined as >50% diameter obstruction of a major coronary vessel. Extent of disease was defined as the number of major coronalry arteries with significant occlusive disease. RESULTS: 1) Statistically significant risk factors between one vessel disease group and multivessel disease group are age, TC, LDL-C, and diabetes in total patients and age, LDL, and diabetes in male patients. But there is no significant difference in female patients. 2) In patients with multivessel disease, age, HDL-C level are significantly lowere, and TG level and the percentage of smkoing are significantly higher, in male than female. 3) There is increase in four major risk factors(diabetes, hypertension,smoking,hypercholesterolemia) with the increased number of diseasesd coronary arteries; normal coronary group has 1.07 risk factors, one vessel disease group 1.30, two vessel disease group 1.49, and three vessel disease group 1.78. 4) In total and male patients, three independent variables are significantly associated with severity of CAD. These variables are age, smoking, and diabetes. In female patients, diabetes in only significant independent risk factor. CONCLUSION: The significant independent risk factors associated with severity of CAD are age, diabetes, and smoking in total and male patients. Whereas in female patients, diabetes is only significant independent risk factor.

Low vital capacity is a risk factor for scoliosis correction operation in Duchenne muscular dystrophy (DMD) patients, but pulmonary rehabilitation, including noninvasive intermittent positive pressure ventilator application, air stacking exercise, and assisted coughing technique, reduces the pulmonary complications and perioperative mortality risk. In this case, the patient's preoperative forced vital capacity (FVC) was 8.6% of normal predicted value in sitting position and 9.4% in supine position. He started pulmonary rehabilitation before the operation and continued right after the operation. Scoliosis correction operation was successful without any pulmonary complications, and his discomfort in sitting position was improved. If pulmonary rehabilitative support is provided properly, FVC below 10% of normal predicted value is not a contraindication of scoliosis correction operation in DMD patients.
