With the rapid development of MS technologiesy, the demands for a more sophisticated MS interpretation algorithm haves grown as well. We have developed a new protein fingerprinting method using a binomial distribution, (fBIND). With the fBIND, we improved the performance accuracy of protein fingerprinting up to the maximum 49% (more than MOWSE) and 2% than(at a previous binomial distribution approach studied by of Wool et al.) as compared to the established algorithms. Moreover, we also suggest a the statistical approach to define the significance of transcription factors and motifs in the identified proteins based on the Gene Ontology (GO).

Prenatal ultrasonographic appearance and Doppler characteristics of extracranial masses are variable, depending on the location, vasculature, amount of arteriovenous shunting, and degree of proliferation. Epidermoid cysts are found in a variety of locations around the skull and midface. They are thought to occur as a result of the persistence of ectodermal elements at sites of suture closure, neural tube closure, and diverticulation of the cerebral hemispheres. They contain ectoderm but no skin element. We experienced 33-year-old primigravida with fetal extracranial mass at 23 weeks gestation. We presumed that this extracranial mass was hemangioma. However, the mass was suspected as scalp epidermoid cyst on postnatal ultasonography.

OBJECTIVE: Percutaneous vertebroplasty is often complicated by the presence of multiple fractures or non-localizing pain in the patients with osteoporotic vertebral fractures. The purpose of this study is to estimate the value of preoperative radiologic studies in the localization of symptomatic vertebrae and to determine the factors which can influence on the clinical results. MATERIALS AND METHODS: We retrospectively reviewed the clinical and radiologic data of 57 vertebrae in 30 patients underwent percutaneous vertebroplasty for osteoporotic vertebral compression fractures. Inclusion criteria was severe pain(McGill-Melzack score 3, 4 or 5) associated with the acute vertebral fractures and absence of spinal nerve root or cord compression sign. Acute symptomatic vertebral fracture was determined by the presence of signal change on MR images or increased uptake on whole body bone scan. RESULTS: Pain improvement was obtained immediately in all patients and favorable result was sustained in 26 patients(86.7%) during the mean follow-up duration of 4.7 months(5 complete pain relief, 21 marked pain relief). Those who underwent vertebroplasty for all acute symptomatic vertebrae had significantly better clinical result than those who did not. Further vertebral collapse and eventual bursting fracture occurred in 1 vertebra which showed intradiskal leakage of bone cement and disruption of cortical endplate on postoperative CT scan. CONCLUSION: Preoperative MR imaging and whole body bone scan are very useful in determining the symptomatic vertebrae, especially in the patients with multiple osteoporotic vertebral fractures. To obtain favorable clinical result, the careful radiologic evaluation as well as clinical assessment is required. Control of PMMA volume seems to be the most critical point for avoiding complications.

Warfarin is an oral anticoagulant which is known to cross the placenta causing birth defects, known as warfarin embryopathy; fetal effects of early gestational exposure to warfarin is known to cause marked nasal hypoplasia, rhizomelia, and stippled epiphyses. The period of greatest sensitivity is 6 to 9 weeks of gestational age. Clinical studies have suggested that discontinuing warfarin before 6 weeks of gestational age could avoid the teratogenic effect. We experienced a women who had been taking warfarin for 15 years because of SLE (Systemic Lupus Erythematosus) and CRF (Chronic renal failure), who was found to be pregnant at 9 weeks of gestation. She discontinued warfarin and started heparin treatment, however the ultrasound examination showed shortened long bone, scalp edema, and cardiac anomaly (Ventricular septal defect), and termination of pregnancy was performed at 17 weeks of gestation. We report a case of warfarin embryopathy resulting from warfarin exposure until 9 weeks of gestation with a brief review of literature.

OBJECTIVE: Panic disorder (PD) is frequently comorbid with insomnia, which could exacerbate panic symptoms and contribute to PD relapse. Research has suggested that characteristics are implicated in both PD and insomnia. However, there are no reports examining whether temperament and character affect insomnia in PD. Thus, we examined the relationship between insomnia and personality characteristics in PD patients. METHODS: Participants were 101 patients, recruited from 6 university hospitals in Korea, who met the DSM-IV-TR criteria for PD. We assessed sleep outcomes using the sleep items of 17-item Hamilton Depression Rating Scale (HAMD-17)(item 4=onset latency, item 5=middle awakening, and item 6=early awakening) and used the Cloninger's Temperament and Character Inventory-Revised-Short to assess personality characteristics. To examine the relationship between personality and insomnia, we used analysis of variance with age, sex, and severity of depression (total HAMD scores minus sum of the three sleep items) as the covariates. RESULTS: There were no statistical differences (p>0.1) in demographic and clinical data between patients with and without insomnia. Initial insomnia (delayed sleep onset) correlated to a high score on the temperamental dimension of novelty seeking 3 (NS3)(F1,96=6.93, p=0.03). There were no statistical differences (p>0.1) in NS3 between patients with and without middle or terminal insomnia. CONCLUSION: The present study suggests that higher NS3 is related to the development of initial insomnia in PD and that temperament and character should be considered when assessing sleep problems in PD patients.

The purpose of this study was to evaluate the viability of periodontal ligament cell in rat teeth using slow cryopreservation method with magnetic field through MTT assay and TUNEL test. For each group, 12 teeth of 4 weeks old white female Sprague-Dawley rat were used for MTT assay, and 6 teeth in TUNEL test. The Maxillary left and right, first and second molars were extracted as atraumatically as possible under tiletamine anesthesia. The experimental groups were group1 (immediately extraction), group 2 (cold preservation at 4degrees C for 1 week), group 3 (rapid cryopreservation in liquid nitrogen), group 4 (slow cryopreservation with magnetic field of 1 G), and group 5 (slow cryopreservation). F medium was used as preservation medium and 10% DMSO as cryoprotectant. After preservation and thawing, the MTT assay and TUNEL test were processed. One way ANOVA and Scheffe method were performed at the 95% level of confidence. The value of optical density obtained after MTT analysis was divided by the value of eosin staining for tissue volume standardization. In both MTT assay and TUNEL test, it had showed no significant difference among group 3, 4, and 5. And group 3 had showed higher viability of periodontal ligament cell than group 2. From this study, slow cryopreservation method with magnetic field can be used as one of cryopreservation methods.

PURPOSE: The purpose of this prospective multi-institutional study was to evaluate the nutritional status of patients undergoing radiotherapy (RT) for treatment of head and neck, lung, or gastrointestinal cancer. MATERIALS AND METHODS: A total of 1,000 patients were enrolled in this study at seven different hospitals in Seoul, Korea between October 2009 and May 2010. The nutritional status of patients after receiving 3 weeks of RT was evaluated using subjective global assessment (SGA). The nutritional status of each patient was rated as well nourished (A), moderately malnourished (B), or severely malnourished (C). RESULTS: The mean age of patients in this study was 59.4 +/- 11.9 years, and the male to female ratio was 7:3. According to the SGA results, 60.8%, 34.5%, and 4.7% of patients were classified as A, B, or C, respectively. The following criteria were significantly associated with malnutrition (SGA B or C; p < 0.001): loss of subcutaneous fat or muscle wasting (odds ratio [OR], 11.473); increased metabolic demand/stress (OR, 8.688); ankle, sacral edema, or ascites (OR, 3.234); and weight loss > or =5% (OR, 2.299). CONCLUSION: SGA was applied successfully to assess the nutritional status of most patients. The prevalence of malnutrition in a radiation oncology department was 39.2%. The results of this study serve as a basis for implementation of nutrition intervention to patients being treated at radiation oncology departments.

PURPOSE: This study aim to investigate the occurrence of autoimmune thyroid disease in children and adolescents at onset of type 1 diabetes mellitus (T1DM) and to assess whether the presence of diabetes-specific autoantibodies can predict the autoimmune thyroid disorder. METHODS: Seventy-three children with T1DM were recruited. Glutamic acid decarboxylase antibodies (GADA), islet cell antibodies (ICA), insulin autoantibodies (IAA), and thyroid antibodies were determined in all patients at the time of diagnosis. RESULTS: The majority of patients (87.7%) had at least one pancreatic antibody (74.0% for GADA, 20.5% for ICA, and 24.7% for IAA). Thyroid autoantibodies were found in 19 of 73 patients (26.0%) at diagnosis. Thyroid autoimmunity (TA) incidence was not statistically significant by GADA or ICA positivity, but significantly higher by IAA positivity (P=0.03), and IAA positivity showed odds ratio, 4.931; 95% confidence interval, 1.323-18.381 for TA. CONCLUSION: The IAA positivity in children and adolescents with TIDM was strongly related to positivity of thyroid autoantibodies and thus it could serve as an index for early prediction of the development of the thyroid autoimmune disorder among children and adolescents with TIDM.
