ABSTRACT
OBJECTIVE: High precise evaluation of the nasopalatine canal morphology is essential to perform detailed diagnosis and treatment plans in implantology and the orthodontic field. We aimed to study morphometric analysis measurements of the nasopalatine canal. MATERIAL AND METHODS: In this cross-sectional study, maxillary CBCT images from 125 patients were evaluated in the Maxillofacial Radiology department between 2014-2021. Sagittal views were assessed to determine nasopalatine canal morphology and dimensions. The difference in canal diameter and length between genders was evaluated using an One Way ANOVA test. RESULTS: There was no significant sex difference among all 125 cases in nasopalatine canal diameter, length, anterior bone plate width. The average length of the nasopalatine canal was 16.49±2.8 mm in male, 16.20±2.9 mm in female, incisive foramen diameter in the sagittal plane was 4.04±0.9 mm in male, 4.02±0.9 mm in female, nasopalatine foramen diameter was 4.63±1.4 mm in male, 4.75±1.2 mm in female. The width of the bone anterior to the canal was 5.89±1.4 mm in males, 5.69±1 mm in females. CONCLUSION: 16-48 aged Mongolian average length of the nasopalatine canal was 16.3 mm, and average incisive foramen width was 4.08 mm, the average width of the bone anterior to the canal was 5.76 mm. Anterior retraction treatment for upper incisor root can be done safely without root resorption around 5.5 mm in the premaxillary alveolar bone.

Background: Increasing evidence points to a link between histone deacetylases (HDACs) and tumorogenesis. Although several HDAC inhibitors have been tested in clinical trials for cancer therapies, the mechanisms of HDAC activation in tumors remain unknown. METHODS Material and Method of HDACI on gallbladder carcinomas: The expression of HDAC protein is studied by immunohistochemistry in 31 specimens of gallbladder carcinoma. Formalin fixed and paraffin embedded specimens were obtained from 35 and 31 consecutive patients. Who had an undergone surgical treatment between 1994 and 2003 at the Department of Digestive Intestinal Surgery, Institute of Health biosciences, the University of Tokushima Graduate School. Antibody: IIDAC1 (C-19): sc-6298 goat polyclonal antibody [Santa Cru/| Assessment of HDACI staining section tissue: In this cases was assigned the following scores: 0 point: <10%; 1+ point, 10-50%; 2+ point, <50% positive cells. For statistical analysis, the cutoff values for positive expression 10% than niorc for HDACI. RESULTS HDACI (+) positive expression was 20 (64.5%) of 31 eases. IIDACI(-) negative expression was 11 (35.5%) of 31 cases.
