Therapy Delivery

Innovative technologies are being developed to make current ablation procedures safer and easier. Sometimes conventional ablation catheters cannot easily adapt to anatomical targets, making radiofrequency applications challenging, time consuming or even ineffective. The Cool Flex is a novel, flexible and fully-irrigated tip catheter with an innovative design and various angular orientations to better adapt the ablation tip to the surrounding tissue. Here, peliminary experience with this new ablation catheter is reported in the treatment of different tachyarrhythmias, including slow and accessory pathway ablation, cavotricuspid isthmus-dependent atrial flutter and atrial fibrillation. One or two radiofreqency applications may be sufficient to eliminate the arrhythmogenic substrate in most patients without complications.

This research aims at investigating the effect of story mapping strategy on grade VIII students’ achievement in writing narrative text. It was conducted by using experimental research design. The Population of this research was the eighth (VIII) grade students of St. Thomas 1 Junior High School Medan. There were two classes as the sample. The first class (VIII-F) as the experimental group, while the second class (VIII-B) as the control group. The experimental group was taught by using story mapping strategy while control group was taught by using lecturing strategy. The instrument for collecting the data was writing test. The data were analyzed by using t-test formula. The analysis showed that the score of students in the experimental group by using story mapping strategy was higher than the score of students in the control group by using lecturing strategy, at the level of significance (α) 0.05 with the degree of freedom (df) 38, the t-observed was 2,818 while the t-table was 2,024. Therefore, the applying of story mapping strategy significantly affected the students’ achievement in writing narrative text.

Abstract Populus deltoides, P. nigra, and P. trichocarpa are the most important species for poplar breeding programs worldwide. In addition, Populus has become a model for fundamental research on trees. Linkage maps were constructed for these three species by analyzing progeny of two controlled crosses sharing the same female parent, Populus deltoides cv. S9-2 × P. nigra cv. Ghoy and P. deltoides cv. S9-2 × P. trichocarpa cv. V24. The two-way pseudotestcross mapping strategy was used to construct the maps. Amplified fragment length polymorphism (AFLP) markers that segregated 1:1 were used to form the four parental maps. Microsatellites and sequence-tagged sites were used to align homoeologous groups between the maps and to merge linkage groups within the individual maps. Linkage analysis and alignment of the homoeologous groups resulted in 566 markers distributed over 19 groups for P. deltoides covering 86% of the genome, 339 markers distributed over 19 groups for P. trichocarpa covering 73%, and 369 markers distributed over 28 groups for P. nigra covering 61%. Several tests for randomness showed that the AFLP markers were randomly distributed over the genome.
