The application of Nd:YAG laser and irrigants to the root surface can change its surface configurations. The purpose of this study was to investigate the effects of Nd:YAG laser and irrigants on the apical seal of obturated canals. In this study, 66 single rooted teeth were randomly assigned to 4 group of 14 teeth each. 8 teeth were served us positive and negative controls. The teeth were divided into 6 groups as follows. Group A: Nd:YAG laser, 5% NaOCl + Rc-prep Group B: Nd:YAG laser, Saline Group C: 5% NaOCl + Rc-prep Group D: Saline Group E: Positive control Group F: Negative control 66 teeth were instrumented using Maillefer ProFile$^{\circledR}$ (Orifice Shapers, .04 taper, .06 taper Dentsply, Switzerland). Two of each group were selected at random, and the canal wall surfaces were examined under a SEM. 12 teeth of each group were obturated using by lateral condensation technique. Specimens were immersed in india ink for 7days, decalcified by 10% nitric acid, dehydrated by 75. 80. 85, 90, 95 and 100% alcohol in order cleared by methyl salicylate and then measured of dye penetration with stereomicroscope($\times$15 magnification) and Image Pro plus. The data were analyzed statistically by one-way ANOVA test and Duncan's Multiple Range test. The results were as follows : 1. The mean leakage was 0.128$\pm$0.376 for group A, 0.237$\pm$0.325 for group B, 0.397$\pm$0.468 for group C, 0.586$\pm$0.402 for group D, and there were statistically significant differences between group A and group D, group B and group D. (p<0.05). 2. Group A had better sealing ability than Group C, but there was statistically no significant differences. (p>0.05). 3. Group B had better sealing ability than Group D and there was statistically significant difference. (p<0.05). 4 Group A had better sealing ability than Group B, but there was statistically no significant difference. (p>0.05). 5. Group C had better sealing ability than Group D, but there was statistically no significant difference. (p>0.05). 6. As a result of observation under SEM, Smear layers were removed in Group A, B. but Smear layers were partially removed and smear plugs were remained in Group C, Smear layers were not removed in Group D. To be specially, Melting of smear layer were showed in Group C. 7. These results suggests that the laser has a potential in reducing the apical microleakage of obturated canals.

Purpose: This prospective study was performed to evaluate the usefulness of preoperative radioimmunoscintigraphy and intraoperative scintimetric examination (radioimmunoguided surgery: RIGS) using $^{99m}Tc-anti-CEA\;F(ab')_2$ fragment. Materials and Methods: Nineteen patients with rectal cancer underwent preoperative whole body planar scintigraphy at 4 hours after injection of $^{99m}Tc-anti-CEA\;F(ab')_2$ fragment and SPECT imaging at 18 hours. Surgical operation was performed at 24 hours after injection. During laparotomy, radioactivities from intraabdominal viscera were measured by gamma probe. The radioactivities from excised tumor and lymph nodes were also measured and compared with pathology. Results: All nineteen patients were confirmed to have adenocarcinomas in the rectum. Twenty-seven of 97 excised lymph node groups had metastasis and 2 patients had liver metastasis in pathology Preoperative radioimmunoscintigraphy detected primary tumors in 11 patients (sensitivity 55%) and it could not detect any lymph nodes or liver metastasis. All patients showed high radioactivity in the kidneys, liver, spleen, and major vessels in intraoperative measurement by gamma probe, and tumor activity was not discriminated from background activity However, radioactivity from excised tumor was higher than normal rectum (T/B ratio; $3.47{\pm}2.25$). When excised lymph node activity/background activity ratio >1.5 was considered as positive criteria of metastasis, sensitivity, specificity, positive and negative predictive values were 78.6%, 73.9%, 55.0% and 89.5%, respectively. Conclusion: Radioimmunoscintigraphy using $^{99m}Tc-anti-CEA\;F(ab')_2$ has no additional value for preoperative staging and use of early RIGS using $^{99m}Tc-anti-CEA\;F(ab')_2$ is inappropriate. For early RIGS using $^{99m}Tc$ labeled antibodies in rectal cancer patients, further development of more specific antibodies and methods to reduce background activity are needed.

'Dahan' (Avena sativa L.), a winter oat cultivar for forage use, was developed by the breeding team at the Department of Rice and Winter Cereal Crop, National Institute Crop Science (NICS), Rural Development Administration (RDA) in 2011. It was derived from an original cross between $F_1$[Sprinter/73625] and 'Gwiri26'. Subsequent generations followed by the cross were handled in bulk and pedigree selection programs at Suwon. A line, 'SO99027-GB-B-113-4-4-3', was selected for cold tolerance and good agronomic characteristics and as a line name of 'Gwiri75'. The line 'Gwiri75' was subsequently evaluated for cold tolerance and forage yield during 3 years in four region such as Yesan, Iksan, Kimjae, and Jeju, from 2009 to 2011 and finally named as 'Dahan'. Though similar in heading date to the check cultivar Samhan, 'Dahan' had tall plant length and lodging resistance. It's average forage dry matter yield harvested at milk-ripe stage was 15.6 ton $ha^{-1}$, compared with 14.1 ton $ha^{-1}$ of check cultivar. Cultivar 'Dahan' was lower to the check cultivar 'Samhan' in protein content (8.4% and 9.9%, respectively), while it was superior to the check cultivar in total digestible nutrients (TDN) (60.8% and 59.3%, respectively), and in TDN yield $ha^{-1}$ (9.5 ton and 8.4 ton, respectively). Fall sowing of 'Dahan' is recommended only in the areas where daily minimum mean temperatures are averaged higher than $-7^{\circ}C$ in January, and excluded in mountain area where frost damage is presumable.

To characterize plasmids in Xanthomonu axonopodis pv. glycines, we isolated plasmids pAG1 from the strain AG1 and pXAG81 and PXAG82 from the strain Bra, respectively, and sequenced three plasmids. The size of plasmids, pAG1, pXAG81, and pXAG82 was 15,149-base pairs (bp), 26,727-bp, and 1,496-bp, respectively Fifteen and twenty six possible open reading frames (ORFs) were present in pAG1 and pXAG81, respectively. Only one ORF homologous to a rep gene of Xylella fastidiosa was present in pXAG82. pAG1 contained genes homologous to avrBs3, tnpA, tnpR, repA, htrA, three parA genes, M.XmaI, R.XmaI, and six hypothetical proteins. pXAG81 contained genes homologous to avrBs3, tnpA, tnpR, repA, htrA, two parA genes, pemI, pemK, mobA, mobB, mobC, mobD, mobE, trwB, traF, traH, ISxac2, and eleven hypothetical proteins. Based on DNA sequence analysis, we presume that pXAG81 is a conjugal plasmid. Interestingly, we found 0.5-kb truncated avirulence gene similar to aurXacE3 on the right border of avrBs3 homolgs of pAG1 and pXAG81. Two hundred twenty five isolates were analyzed to find aurBS3 or tra gene homologs by Southern hybridization. The numbers of avrBs3 homolog varied from 3 in AG1 to 8 in AG166. Two hundred seventeen isolates appeared to can conjugative plasmids (pXAG81 type), and thirty eight isolates appeared to carry non-conjugative plamids (pAGl type). This indicated that aurBs3 gene homologs might be spread by conjugation in X. axonopodis pv. glycines.

Many enzymes catalyze a primary reaction and/or secondary reaction. Dextransucrase usually synthesizes dextran from sucrose as a primary reaction. The secondary reaction of dextransucrase is the transfer of glucose from sucrose to carbohydrate accepters. We have reacted dextransucrase from Leuconostoc mesenteroides B-742CB with sucrose and pullulan as an acceptor under different reaction conditions; various concentrations of pullulan, enzyme, sucrose and different pHs and temperatures of reaction digests. The yield of modified pullulan was 57%(<${\pm}$5%) of theoretical under the reaction condition of pH 5.2, temperature 28$^{\circ}C$, 0.37% of pullulan, and 0.l U/$m\ell$ of dextransucrase. Modified products were more resistant against the hydrolysis of pullulanase and endo-dextranase than those of native pullulan. The positions of glucose substitution in the modified products were determined by methylation followed by acid hydrolysis and analyzed by TLC. The products were modified by the addition of glucose to the position of C3, C4, C6 free hydroxyl group of glucose residues in the pullulan.

In this study we demonstrate ultrahigh-resolution spectral domain optical coherence tomography (UHR SD-OCT) with a linear-wavenumber (k) spectrometer, to accelerate signal processing and to display two-dimensional (2-D) images in real time. First, we performed a numerical simulation to find the optimal parameters for the linear-k spectrometer to achieve ultrahigh axial resolution, such as the number of grooves in a grating, the material for a dispersive prism, and the rotational angle between the grating and the dispersive prism. We found that a grating with 1200 grooves and an F2 equilateral prism at a rotational angle of $26.07^{\circ}$, in combination with a lens of focal length 85.1 mm, are suitable for UHR SD-OCT with the imaging depth range (limited by spectrometer resolution) set at 2.0 mm. As guided by the simulation results, we constructed the linear-k spectrometer needed to implement a UHR SD-OCT. The actual imaging depth range was measured to be approximately 2.1 mm, and axial resolution of $3.8{\mu}m$ in air was achieved, corresponding to $2.8{\mu}m$ in tissue (n = 1.35). The sensitivity was -91 dB with -10 dB roll-off at 1.5 mm depth. We demonstrated a 128.2 fps acquisition rate for OCT images with 800 lines/frame, by taking advantage of NVIDIA's compute unified device architecture (CUDA) technology, which allowed for real-time signal processing compatible with the speed of the spectrometer's data acquisition.

Background: An association between the ABO groups and pancreatic cancer has been shown previously, group A being significantly commoner in affected patients. We conducted the present study to investigate the prognostic effect of ABO blood group on overall survival of pancreas cancer patients. Methods: Patients who were diagnosed between 2005 and 2010 with pancreas cancer at Ankara Numune Education and Research Hospital were analyzed retrospectively. Patient demographics and ABO blood groups were obtained from medical charts. Results: Fifty pancreas cancer patients with known ABO blood group were included, 26 (52%) group A, 12 patients (24%) group 0, 9 (18%) group B, and 3 (6%) group AB. Blood group A pancreas cancer patient median age was 61.5 (39-80) years, with the median age of the other blood groups (B, AB,O) being 55.5 (32-74) years (p=0.14). 18% of patients with blood group A and 11% of the other blood group patients had metastasis (p=0.17) at the time of diagnosis. The median overall survival of blood group A pancreas patients was significantly lower than the other blood group patients, 7.6 (95%CI: 5.0-10.2) months versus 29.0 (95%CI: 0.0-68.8) months (p=0.05). Conclusions: Acccording to previously published cohort studies a relation may exist between ABO blood groups and cancer of pancreas. In this study we observed that pancreas cancer patients with blood group A have significantly worse overall survival than other blood groups.
