Introduction: Angle’s method still seems to be the most popular tool for classification of malocclusion. Confusion arises in the community of Orthodontic regarding the classification and interpretation of subdivision malocclusion in Angle’s classification system. The purpose of this study was to survey orthodontists in West Java to determine their consistency in classifying subdivision malocclusion and their viewpoints on the meaning of subdivision. Methods: The type of research was descriptive with survey method by using questionnaire. The study uses total sampling technique with some inclusion criteria. Data obtained were analyzed and presented in table form. Results: Of the 80 respondents, 71.3% is consistent, 22.5% is doubtful and 6.6% is inconsistent in classifying subdivision malocclusion. 37 respondents (46.25%) believe that subdivision refers to the Class II side, 20 respondents (25%) believe it refers to the Class I side 4 respondents (5%) says subdivision refers to neither Class I nor Class II side and 19 respondents (23.75%) says that subdivision referred to both side. Conclusion: Most of orthodontists are consistent in classifying subdivision malocclusion, majority of the responded orthodontists stated that subdivision refers to the abnormal side of the arches and most of the responded orthodontist use Proffit and Common usage as their source of reference.

Rafflesia patma is an endemic plant of Pangandaran, West Java which is protected because of its rare status. The purpose of this research is to study the population structure, distribution patterns, and the effect of the physical environment of abundance R. patma in Pananjung Pangandaran Nature Reserve, West Java. The method used in this research was a survey method with a purposive sampling technique. Sampling was conducted using quadrat plots. The population pattern distribution was defined by a standardized Morisita index, and the analysis of abiotic environmental factors was determined by Principal Component Analysis (PCA) using PAST3. The results showed that there were 114 R. patma individuals scattered in several research areas in Pananjung Pangandaran Nature Reserve, they were Gua Parat (3 individuals), Cilegon (13 individuals), Pasir Putih (12 individuals), Badeto (48 individuals), and Curug Leutik (38 individuals). The distribution pattern of R. patma in Pananjung Pangandaran Nature Reserve was clustered with the Morisita index value (Id) > 1. Based on the PCA analysis, results that support the classification of the cluster analysis were obtained. Based on four abiotic environmental conditions analyzed, the most dominant character in influencing the distribution patterns and population structure of R. patma is light intensity.

Our goal in this present study is to introduce new wavelet based methods for differentiating and classifying Class I and Class II PDZ domains and compare the resulting signals. PDZ domains represent one of the most common protein homology regions playing key roles in several diseases. To perform the classification, we developed two methods. The first of our methods was comparable to the standard wavelet approaches while the second one surpasses it in recognition accuracy. Our models exhibited interesting results, and we anticipate that it can be used as a computational technique to screen out the misfit candidates and to reduce the search space, while achieving high classification and accuracy.

Although a large number of bronze ‘razors’ have been found in these islands, the literature concerning them is very scattered, and there has been no attempt to synthesize the information concerning them. There are frequent references to the so-called ‘plantain’ (our Class I) form or to the ‘maple-leaf’ (Class II) examples with their suggested connection with Siculan razors, but there has been no detailed analysis of their chronological and cultural positions in the British Late Bronze Age. This paper attempts such a classification of the razors on a typological and cultural basis so that they can be fitted with greater accuracy intq their place in Late Bronze chronology.

BACKGROUND To provide efficient and well-planned orthodontic treatment orthodontists must be able to assess the type of malocclusion and the complexity involved in its treatment. Hence, the purpose of this study was to validate index of orthodontic treatment complexity (IOTC) as a reliable index to assess the treatment complexity in treating different malocclusion groups. METHODS A retrospective study with sample of 120 pairs of orthodontic study model consisting of treated and untreated cases, were collected and equally divided into class I, class II including both division 1 and division 2 and class III malocclusions based on Angles system of classification of malocclusion. Study casts were scored according to criteria given by the index of orthodontic treatment complexity and the degree of complexity is established for each of the malocclusion groups and the occlusal traits. RESULTS The Spearman correlation coefficients test shows that occlusal traits like overjet, centreline discrepancy, molar correction, overbite, crowding, posterior cross bite, alone significantly correlated with degree of complexity. Multiple regression analysis and one way ANOVA tests were performed for the three types of malocclusion and the test showed that in individual classes of malocclusion, the predictor variable (occlusal traits) significantly predicts the degree of complexity in class I and class II malocclusion cases, but not in class III. CONCLUSIONS Overjet, centreline discrepancy, molar correction, overbite, crowding, posterior cross bite correlated with degree of complexity. IOTC forecasts the degree of complexity in class I and class II malocclusion cases, but not in class III. KEY WORDS IOTC, Malocclusion, Occlusal Traits

e15530 Background: CTCs have been widely used in monitoring the efficacy and prognosis of lung cancer. However, CTCs number count alone cannot accurately predict the recurrent disease in patients. In this study, we investigate whether the morphology classification of CTCs could be as a prognostic marker for increased risk of recurrence after surgery. Methods: In this study, 105 lung cancer patients (median age 68y) who underwent surgery were prospectively enrolled in this study. Samples were obtained before, after, and serially up to 24 months after surgery. CTCs were collected and morphology classified by utilizing a CTC test workflow which uses negative enrichment and immunofluorescence methods to capture and identify CTCs from blood sample. Captured CTCs (epithelial type) were screened with a customized imaging analysis pipeline, a cytological profile of each CTC was created, including cell size, shape, fluorescent intensity and texture etc. Results: The CTC detection rate was 78.1% (78 of 105) prior to surgery, and a total of 726 CTCs were enumerated. Median CTC count number was 3. 5 classes of CTCs with distinct morphological features were observed in lung cancer patients’ CTC tests, briefly, CTC class I and class II possessed large nuclei but relatively lower epithelial expression level, CTC class III, IV, V possessed small nuclei but relatively higher epithelial expression level, CTC class III possessed irregular shaped nuclei, CTC class V possessed relatively lower nuclei/cytoplasm ratio. Class III accounted for the highest proportion of captured CTCs III, about 35.5% with Class I 14.8%, Class II 15.3%,Class IV 17.8% and Class 5 16.6%. Postoperative recurrence and metastasis were observed in 16 patients. CTCs positive were found in 14 patients (87.5%). 145 CTCs were collected, Median CTC count number was 3,Cluster III accounted for 47.3%, with Class I 11.8%,Class II 13.3%,Class IV 14.5% and Class V 11.8%; Patients with Cluster 3 dominant were associated with increased risk of local recurrence ( p < 0.05) and distant metastasis ( p < 0.05). Conclusions: Small and irregular nuclei CTC is significant associated with increased risk of recurrence disease. Morphology Classification of circulating tumor cells is feasible in monitoring the recurrence of disease and may potentially identify the patients who may benefit from further therapy.
