Back.round. Mucosa-associated lymphoid tissue (MALT) lymphoma involving multi ple organs is not well characterized. Methods. To obtain a better understanding of gastric MALT lymphoma with multiple organ involvement, we compared Helicobact er pylori infection status; response to eradication therapy; prevalence of genet ic abnormality, including t(11;18)-(q2l;q2l); and clonality of tumor cells betw een patients with gastric MALT lymphoma with and without multiple organ involvem ent. Results. Of 54 patients with only gastric involvement, 51 were positive for H. pylori (94.4%), whereas only 3 of 9 patients with multiple organ involvemen t had the infection (33.3%). Among those who received eradication therapy, the remission rate in patients with only gastric involvement was significantly highe r than that in patients with multiple organ involvement (71.4%vs 33.3%; P < 0. 05). The positive rate of AP12-MALT1 fusion transcripts was significantly great er in patients with multiple lesions with either single or multiple organ involv ement than in those with a single gastric lesion (71.4%vs 12.5%; P < 0.05), bu t 2 of 2 patients with multiple gastric lesions had the fusion transcripts. Of 5 patients with multiple organ involvement tested for clonality of the CDR3 regio n, distinct clones were detected in lymphoma lesions in different organs in 3 pa tients, whereas the identical clone was present in the different lesions in the remaining 2 patients. Conclusions. Gastric MALT lymphoma with multiple organ inv olvement is often associated with API2-MALT1 fusion transcripts. Moreover, H. p ylori infection is rare in patients with multiple organ involvement as compared to those with only gastric involvement. Patients with gastric MALT lymphoma with multiple organ involvement who are positive for H. pylori are resistant to erad ication therapy.

Back.round: The safety and efficacy of Seprafilm (Genzyme Corporation, Cambrid ge, Mass) in adult surgery patients have been established. The aim of this study was to evaluate the safety and efficacy of Seprafilm in pediatric surgical pati ents. Methods: One hundred twenty-two pediatric abdominal surgery patients were enrolled. Sixty-seven patients received Seprafilm application. Of these patien ts, 18 again received Seprafilm at abdominal closure during a second surgery, an d of the 18, 4 received Seprafilm at closure after a third surgery. Of the 55 co ntrol patients who did not receive Seprafilm, 14 had a second surgery, and of th ese 14 patients, 4 had a third surgery. Adverse events, operation time, and bloo d loss were compared with assessed Seprafilm safety. Seprafilm efficacy evaluati ons included incidence and severity of adhesions in those patients who required relaparotomy. Results: The incidence (Seprafilm, 40.9%; control, 82.4%) and se verity (Seprafilm: 59.1%, grade 0; control: 17.6%, grade 0) of adhesions under the abdominal incision site were significantly reduced in the Seprafilm group ( P = .007 and P = .0009, respectively). In addition, mean relaparotomy operation time was significantly shorter for Seprafilmpatients (P = .004). At relaparotomy , blood loss/body weight ratio for Seprafilm patients compared with control pati ents showed a trend toward but did not reach significance (P = .09). Conclusions : Decreased incidence and severity of postsurgical adhesions with Seprafilmin pe diatric patientsmay lead to reduction of the risk. associated with subsequent op eration.

PURPOSE: This study was designed to clarify a limit for steroid therapy in patients with ulcerative colitis through analyzing the preoperative major steroid-related complications and to define when alternative therapies, including surgery, should be performed in pediatric ulcerative colitis patients. METHODS: The medical records of 28 pediatric and 57 adult patients with ulcerative colitis who underwent total proctocolectomy and ileal J-pouch-anal anastomosis were reviewed. The relationship between the preoperative dose of glucocorticoids and major steroid-related complications, as well as the surgery variables, was evaluated. RESULTS: Significantly higher incidences of growth retardation, osteoporosis, glaucoma, and cataracts were noted in pediatric patients than in adult patients. In pediatric patients, major steroid-related complications occurred at a significantly lower preoperative total dosage of glucocorticoids/body weight (mg/k.) or preoperative total dosage of glucocorticoids/body surface area (mg/m2) than in adult patients. A similar surgical procedure was performed in both pediatric and adult patients. The presence of major steroid-related complications can lower a patient’s long-term quality of life. CONCLUSIONS: Evidence-based guidelines for the recommended dose of glucocorticoids according to body weight or body surface area are needed. To allow patients to feel well and maintain a good quality of life, early introduction of alternative treatments, including surgery, should be considered.

Convolutional neural network. (CNNs) have had great success with regard to the object classification problem. For character classification, we found that training and testing using accurately segmented character regions with CNNs resulted in higher accuracy than when roughly segmented regions were used. Therefore, we expect to extract complete character regions from seene images. Text in natural scene images has an obvious contrast with its attachments. Many methods attempt to extract characters through different segmentation techniques. However, for blurred, occluded, and complex back.round cases, those methods may result in adjoined or over segmented characters. In this paper, we propose a scene word recognition model that integrates words from small pieces to entire after-cluster-based segmentation. The segmented connected components are classified as four types: back.round, in dividual character proposals, adjoined characters, and strok. proposals. Individual character proposals are directly inputted to a CNN that is trained using accurately segmented character images. The sliding window strategy is applied to adjoined character regions. Strok. proposals are considered as fragments of entire characters whose locations are estimated by a strok. spatial distribution system. Then、the estimated characters from adjoined characters and strok. proposals are classified by a CNN that is trained on roughly segmented character images. Finally, a lexicondriven integration method is performed to obtain the final word recognition results. Compared to other word recognition methods, our method achieves a comparable performance on Street View Text and the ICDAR 2003 and ICDAR 2013 benchmark.databases. Moreover, our method can deal with recognizing text images of occlusion and improperly segmented text images.

In the low aspect ratio torus experiment （LATE） device, plasma current is initiated and ramped up to 20 k. solely by microwave power at the electron cyclotron （EC） range of frequency with a ramp of the external vertical field By for the radial equilibrium of plasma torus at larger currents. Measurements suggest that an energetic electron tail in the energy range of about 200 k.V carries the current. The line averaged electron density is higher than the plasma cutoff density, suggesting that tail electrons might be driven by electron Bernstein waves modeconverted from the launched electromagnetic waves.

Iris pseudacorus L., intentionally introduced in Japan as an ornamental plant and to improve aquatic environments, has been declared a noxious species in the Invasive Alien Species Act of Japan due to the suspected high ecological risk. to the local species and ecosystems. Although prompt responses to I. pseudacorus have been sought to conserve local biodiversity, k.owledge about its invasiveness is lack.ng. Here, we report the relationship between the establishment of I. pseudacorus and floristic changes in semi-wetland vegetation of an abandoned urban pond(Aoik.), Nara City, Nara Prepecture, Japan. In total, 64 vascular plants were recorded in the pond, of which 50 were native species, seven were naturalized non-native, and seven were invasive species. On the other hand, most of these vascular plants(42 species) were grassland species and only several aquatic plants(10 species) were found in this study pond. The number of vascular plant species decreased significantly at quadrats with a coverage of I. pseudacorus above 50%. In addition, tendencies of lower number of native species and concomitant higher number of invasive species were found with increasing coverage of I. pseudacorus. From these results, we suggest that it is important to preferentially manage sites where the coverage of I. pseudacorus is above 50%, in order to preserve the local biodiversity. Additionally, as recommended in the literature, it is essential that the cut reproductive organs are k.pt submerged under deep water for an effective control of I. pseudacorus.

In this paper, we intensively study the behavior of three part-based methods for handwritten digit recognition. The principle of the proposed methods is to represent a handwritten digit image as a set of parts and recognize the image by aggregating the recognition results of individual parts. Since part-based methods do not rely on the global structure of a character, they are expected to be more robust against various delormations which may damage the global structure. The proposed three methods are based on the same principle but different in their details, for example, the way of aggregating the individual results. Thus, those methods have different performances. Experimental results show that even the simplest part-based method can achieve recognition rate as high as 98.42% while the improved one achieved 99.15%, which is comparable or even higher than some state-of-the-art method. This result is important because it reveals that characters can be recognized without their global structure. The results also show that the part-based method has robustness against deformations which usually appear in handwriting.

For strok.-order free online multi-strok. charac- ter recognition, strok.-to-strok. correspondence search be- tween an input pattern and a reference pattern plays an im- portant role to deal with the strok.-order variation. Although various methods of strok. correspondence have been pro- posed, no comparative study for clarifying the relative su- periority of those methods has been done before. In this pa- per, we firstly review the approaches for solving the strok.- order variation problem. Then, five representative methods of strok. correspondence proposed by different groups, includ- ing cube search （CS）, bipartite weighted matching （BWM）, individual correspondence decision （ICD）, stable marriage （SM）, and deviation-expansion model （DE）, are experimen- tally compared, mainly in regard of recognition accuracy and efficiency. The experimental results on an online k.nji char- acter dataset, showed that 99.17%, 99.17%, 96.37%, 98.54%, and 96.59% were attained by CS, BWM, ICD, SM, and DE, respectively as their recognition rates. Extensive discussions are made on their relative superiorities and practicalities.
