Identification of tumor necrosis factor-α levels around miniscrews during canine distalization
Filiz Acun Kaya,Nihal Hamamcı,Ersin Uysal,Beran Yoku? 대한치과교정학회 2011 대한치과교정학회지 Vol.41 No.1
Objective: The aim of this study was to measure tumor necrosis factor-α (TNF-α) levels around miniscrews used for anchorage during a 3-month period of canine distalization. Methods: Sixteen patients (8 boys, 8 girls; mean age, 16.6 ± 2.4 years) whose upper first premolars were extracted for orthodontic treatment were included in this study. Miniscrews were used as an anchorage unit in canine distalization. Thirty-two (32) miniscrew implants were placed bilaterally in the alveolar bone between the maxillary second premolars and first molars. The treatment, miniscrew, and control groups comprised upper canines, miniscrew implants, and upper first premolars, respectively. Peri-miniscrew implant crevicular fluid and gingival crevicular fluid were obtained before applying force and at 1, 24, and 48 hours, and at 7 and 21 days, and 3 months after applying force. Results: During the 3-month period, the TNF-α levels increased significantly at 24 hours only in the treatment group (p < 0.01). In the miniscrew and control groups, there were no statistically significant changes. No significant differences were observed between groups. Conclusions: Miniscrews can be conveniently used for anchorage in orthodontics. (Korean J Orthod 2011;41(1):36-41)

Objective: The aim of this study was to measure tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) levels around miniscrews used for anchorage during a 3-month period of canine distalization.

Adaptive Image Segmentation Based on Histogram Transition Zone Analysis

While segmenting “complex” images (with multiple objects, many details, etc.) we experienced a need to explore new ways for time-efficient and meaningful image segmentation. In this paper we propose a new technique for image segmentation which has only one variable for controlling the expected number of segments. The algorithm focuses on the treatment of pixels in transition zones between various label distributions. Results of the proposed algorithm (e.g. on the Berkeley image segmentation dataset) are comparable to those of GMM or HMM-EM segmentation, but are achieved with significantly reduced computation time.

Intestinal obstruction after liver transplant is a rare complication, with diverse clinical manifestations. Intestinal adhesion is the most common cause. However, internal hernia, abdominal wall hernia, and neoplasm are also reported. Intussusception is another rare cause of intestinal obstruction, which has been reported primarily in pediatric patients. Herein, we report a case of intestinal obstruction from intussusception in an adult liver transplant patient associated with post-transplant lymphoproliferative disorder.
