We describe the repair of the postoperative left main stem stenosis of a 24-day old male patient who initially underwent arterial switch operation for dextro-transposition of the great arteries. The repair was facilitated by using an autologous left innominate vein patch, while there was a shortage of suitable repair material in this neonate. Postoperative echocardiogram prior to discharge conf...

Performance of ATM networks will depend on switch performance and architecture. In this paper a set of eleven questions is presented in order to be able to study the performance. It is necessary to clearly identify the main characteristics of the switch architecture and the traffic that are considered. They concern the level of study, the placement of the memory, the monopath or multipath archi...

conclusions switching ams off may increase biventricular pacing in some patients. case presentation in this case series, we present a combination of far field sensing and automatic mode switching (ams) in six patients. it is found that this combination causes ventricular sensing (vs) episodes with wide qrs and no synchronization. we turn off the ams and alleviate the problem. introduction cardi...

In order to facilitate the removal of peptide nucleic acid (PNA), when necessary, from its duplexes and invasion complexes, a disulfide bond was introduced to its main chain. The disulfide bond was readily cleaved by various reducing agents (2-mercaptoethanol, dl-dithiothreitol, and tris(2-carboxyethyl)phosphine) even when the PNA was forming a duplex with its complementary DNA. The resultant t...

BACKGROUND The advent of combined antiretroviral therapy (ART) in the past decade has led to HIV suppression in most cases. Virological failure was the main reason for ART switch a few years ago; however, toxicity and treatment simplification have now gained importance due to the availability of more effective and convenient drugs. This study assessed the reasons for ART switch in daily practic...

The Internet has created an opportunity for collaboration between scientists at unprecedented levels. Furthermore, in the late 80's, researchers developed general approaches to programmonitoring[1], [2], [3], followed by advances in program adaptation[4] and steering[5]. Speci cally, by coupling program monitoring and steering with online visualizations[6], [7] of scienti c data, it has now bec...

In this issue of Blood, Ware and Helms report results from the Stroke With Transfusions Changing To Hydroxyurea (SWiTCH) study designed to determine whether hydroxyurea is as effective as transfusions in preventing recurrent strokes in children with sickle cell anemia. The finding of strokes in 7 of 67 children receiving hydroxyurea but none in 66 children who received transfusions led the auth...
