Ti–36Nb–2Ta–3Zr–0.35O (TNTZO) alloy is an excellent candidate for biomedical applications. In this study, a new methodcombining cold-swaging and cold-drawing was used to fabricate the TNTZO alloy wires with 0.3 mm diameter for orthodonticapplications. The microstructure and mechanical properties of cold-drawn and annealed TNTZO wires (referred toas TNTZO0.3and TNTZO0.3(HT), respectively) were investigated. The results show that the microstructure of cold drawnTNTZO0.3consists of main-sized elongated grains with 70 nm width. After annealing at 700 °C for 5 min, the microstructureof TNTZO0.3(HT) wires becomes equiaxial with a grain size of ~ 5 μm. The cold drawn TNTZO0.3wires exhibit improvedmechanical properties, higher tensile strength (about 1000 MPa) and similar elastic modulus (69 GPa), compared to annealedTNTZO0.3(HT) wires. Besides, TNTZO0.3has higher creep resistance and lower stress exponent (around 2), compared to Tiwires and TC4 wires with the same diameter. These results prove that TNTZO0.3wires have most of the ideal characteristicsof orthodontic wires.

알코올 유도성 조직 손상에 있어서 adrenomedullin의 발현 및 그 영향에 대한 연구 중, 실험 마우스 중의 한 개체에서 장간막 림프절과 장 내에서 림프육종이 발생한 것을 확인하였다. 림프육종은 마우스 계통에 따라 발생율이 다르지만 알려진 바로는 두 번째로 발생율이 높은 자발성 종양 질환 중 하나이다. 본 증례에서 육안적인 관찰 결과, 절제된 장에서 다소 경도가 높거나 연한 경도를 가지는 부분이 혼재된 크림색의 mass가 내강으로 돌출된 것과 함께 장간막에서 역시 동일한 형태의 mass가 관찰되었다. 종양성 세포들은 주로 점막 내로 침습하고 있는 모습을 나타내고 있으며 원형의 과염색성 핵과 소량의 세포질을 함유하고 있었다. 본 림프계 종양에 있어서 그 세포들의 기원은 CD20, CD3, vimentin에 대한 면역염색을 실시하여 확인하였다. In the study of investigate the expression and effects of adrenomedullin (AM) in the tissue injured by ethanol in our laboratory, there were lymphosarcomas involving mesenteric lymph node and intestine discovered in experimental mice. Lymphosarcoma is probably the second most common spontaneous neoplastic disease, the incidence of which is dependent on the strain of mouse. The diagnosis of lymphosarcoma was based on gross and light microscopic studies. Grossly, the excised intestine and mesentery showed soft-to-firm, cream-colored, displayed protuberance into the lumen. The neoplastic cells had mainly infiltrated into the mucosal and mesenteric lymph node, and have round hyperchromatic nuclei and a small amount of cytoplasm. The origin of these tumor cells was determined by immunohistochemistry positive of CD20, CD3 and Vimentin.

Objective: To meta-analytically compare combined transarterial chemoembolization (TACE) plus radiofrequency ablation (RFA) and surgical resection (SR) for the treatment of hepatocellular carcinoma (HCC) within the Milan criteria. Materials and Methods: PubMed, Medline, Embase, and Cochrane Library were searched for studies comparing these two therapies that were published between January 2006 and August 2017. Overall survival rate (OS), recurrence-free survival rate (RFS), major complications and the average length of hospital stay were compared between these two therapies. Metaanalytic pooled odds ratio (OR) was calculated using TACE plus RFA as the base category. Results: Seven case-control studies and one randomized trial were identified. Meta-analytic results revealed that, compared with SR, TACE plus RFA had significantly higher 1-year OS (OR for survival = 0.50, p = 0.009) and lower major complications (OR = 1.88, p = 0.02) after therapy. Three studies reported on the length of hospital stay. The average length ± standard deviation reported in individual studies for SR and TACE plus RFA groups was 19.8 ± 8.4 days and 7.4 ± 2.2 days, respectively; 18.7 ± 4.9 days and 11.5 ± 6.9 days, respectively; and 16.6 ± 6.7 days and 8.5 ± 4.1 days, respectively (p < 0.0001 for all studies). Three or 5-year OS and 1-, 3-, or 5-year RFS did not significantly differ between the two therapies. Conclusion: Combined TACE plus RFA may be an alternative to SR for the treatment of patients with HCC within Milan the criteria. Non-randomized design in most of the original studies was a limitation.
ATCS: An Adaptive TCP Coding Scheme for Satellite IP Networks
( Wei Dong ),( Junfeng Wang ),( Minhuan Huang ),( Jian Tang ),( Hongxia Zhou ) 한국인터넷정보학회 2011 KSII Transactions on Internet and Information Syst Vol.5 No.5
In this paper we propose ATCS, a practical TCP protocol coding scheme based on network coding for satellite IP networks. The proposal is specially designed to enhance TCP performance over satellite networks. In our scheme, the source introduces a degree of redundancy and transmits a random linear combination of TCP packets. Since the redundant packets are utilized to mask packet loss over satellite links, the degree of redundancy is determined by the link error rates. Through a simple and effective method, ATCS estimates link error rates in real time and then dynamically adjusts the redundant factor. Consequently, ATCS is adaptable to a wide range of link error rates by coding TCP segments with a flexible redundancy factor. Furthermore, the scheme is compatible with traditional TCP variants. Simulation results indicate that the proposal improves TCP performance considerably.

Objective: Explore the feasibility of allo-hemopietic stem cell transplants in treating patients with B cell acute lymphocytic leukemia. Methods: Between september 2006 and February 2011, fifteen patients with B cell acute lymphocytic leukemia (ALL) were treated by allo-hemopietic stem cell transplants (HSCT). Stem cell sources were peripheral blood. Six patients were conditioned by busulfan (BU) and cyclophosphamide (CY) and nine patients were conditioned with TBI and cyclophosphamide (CY). Graft versus host disease (GVHD) prophylaxis regimen consisted of cyclosporine A (CSA), methotrex ate (MTX) and mycophenolatemofetil (MMF). Results: Patients received a median of $7.98{\times}10^8{\cdot}kg^{-1}$ ($5.36-12.30{\times}10^8{\cdot}kg^{-1}$) mononuclear cells (MNC). The median time of ANC> $0.5{\times}10^9/L$ was day 12 (10-15), and PLT> $20.0{\times}10^9/L$ was day 13 (11-16). Extensive acute GVHD occurred in 6 (40.0%) patients, and extensive chronic GVHD was recorded in 6 (40.0%) patients. Nine patients were alive after 2.5-65 months follow-up. Conclusion: Allogeneic stem cell transplant could be effective in treating patients with B cell acute lymphocytic leukemia.

본 증례는 4년령의 암컷 비글종에서 발생한 것으로 점진적인 안구돌출증을 비롯하여 왼쪽 하안구 부속기에 발생한 직경 1.4 cm의 종양을 가지고 있었다. 종양의 병리조직학적 검경에서 증생된 종양 세포들이 소엽 및 섬유성 격벽으로 구분되는 관통상의 구조를 나타내고 있었다. 잘 분화된 피지선은 다양한 크기의 소엽을 형성하고 있으며 비만세포 및 단핵 염증세포의 침윤이 관찰되었다. 관강 내에는 이러한 관성구조의 정점부위에서 탈락되어 나온 호염성 물질이 관찰되었으며 일부 관성구조는 경도의 화생을 나타내고 있었다. 조직면역염색에서 세포집단은 α-SMA와 vimentin에 양성 반응을 나타내었다. 따라서 본 원발성 종양은 안검에서 발생한 내검판선 및 외검판선 유래의 선암종으로 진단되었으며 침윤되고 있는 안구내 종양은 악성 혼합종으로 진단되었다. A 4-year-old female beagle with progressive exophthalmos and which had a neoplastic mass with diameter of 1.4 cm in the left lower ocular adnexa. Histologically, the mass was composed of hyperplastic lobules and tubular structures separated by fibrous septum. The well differentiated sebaceous gland forming various sized lobules, and infiltration of mast cells and mononuclear inflammatory cells were observed. Apical decapitation secretion of these tubular structures with basophilic materials in their lumen showed mild sebaceous gland metaplasia. Immunohistochemical studying, cell groups were positive in α-SMA and vimentin. The primary tumor was diagnosed as adenocarcinoma originated from moll gland and meibomian gland of the eyelid, and the infiltrating intraocular neoplasm was diagnosed as a malignant mixed tumor.

Herein, a novel kind of composite yarn with alternating segmented structure and interval color has been prepared based on a ring spinning approach. By adjusting the relative motion and blend ratio of the colored polyester filament and natural cotton staple fiber in yarn spinning process, a series of composite yarns were designed and prepared with various segmented structure and cyclical change of the distinct colors. The blend ratio was found to strongly influence on the segment frequency and yarn performance, achieving an improved mechanical property and yarn performance. A color systematic analysis indicated that the combination of alternating structural change induced interval color sense and gradient at the merged regions would lead to an enhanced stereoscopic visual effect of the composite yarns. Moreover, the composite yarns were confirmed to have an excellent weavability and able to endow different patterns and visual effects to the textiles. Thus, considering of the above advantages and multifunctionalities, this work should spur great possibilities for dyeing industry with the promising physical spinning method.
