Nursing students' anxiety and clinical performance

This study examined how mood states affect nursing students' performance on a treatment procedure consisting of a novel combination of familiar clinical steps. Thirty third-year and fourth-year nursing students were first taught the procedure and then given both an anxious-mood and a calm-mood induction in a randomly assigned counterbalanced order. Anxiety was induced by showing a video of interviews with frontline nurses and doctors during the severe acute respiratory syndrome epidemic in Hong Kong, China; calmness was induced by a video of a nursing student's pleasant orientation to a clinical placement site. Nursing students were significantly less proficient in performing the newly acquired procedure after an anxious-mood induction (focused on occupational risks) than after a calm-mood induction. Therefore, managing clinical training site anxiety among nursing students may help to optimize learning and clinical performance. © SLACK Incorporated.postprin

Impact of stroke on autonomic nervous system

INTRODUCTION: Disturbances of the autonomic nervous systems (ANS) are not uncommon in stroke patients, attributed to damage of the central autonomic networks. The resultant alternation in autonomic dynamics caused an imbalance between sympathetic and parasympathetic tone. The most common clinical problems include abnormalities in heart rate and blood pressure control. Vasomotor and sudomotor disturbances post stroke are less well defined …published_or_final_versio

Differential NOD/SCID mouse engraftment of peripheral blood CD34 + cells and JAK2V617F clones from patients with myeloproliferative neoplasms

We evaluated the NOD/SCID engraftment of CD34 + cells from polycythemia vera (PV) and secondary polycythemia patients (SP) and the JAK2V617F clone before and after transplantation. Peripheral blood CD34 + cells were transplanted intra-femorally. In the injected BM, successful engraftment (>0.1%) occurred in 8/26 mice transplanted with CD34+ cells from 5/13 PV patients (median: 4.26%, range: 0.3-5.56%), in contrast to 0/14 mice from 9 SP patients (P=0.017). The engrafting PV cells were of multi-lineage. JAK2V617F/total JAK2 ratios decreased after transplantation (initial: 65.9% versus 6-week: 13.0%, P=0.001). Essential thrombocythemia (ET) BM cells also exhibited a similar decrease in JAK2V617F clone. The results suggested that events in addition to JAK2V617F are involved in the pathogenesis of PV and ET. © 2010 Elsevier Ltd.postprin

Epitaxial YBa/sub 2/Cu/sub 3/O/sub y/ thin films grown on silicon with a double buffer of Eu/sub 2/CuO/sub 4//YSZ

We report a double buffer of Eu/sub 2/CuO/sub 4/ (ECO)/YSZ to improve the growth of YBa/sub 2/Cu/sub 3/O/sub y/(YBCO) on Si wafer. The ECO buffer material possesses a very stable 214-T' structure. It has excellent structural and chemical compatibilities with YBCO and YSZ. Our study showed that the epitaxy and crystallinity of YBCO deposited on Si could be considerably enhanced by using such a double buffer of ECO/YSZ. The grown films were characterized by grazing incidence X-ray reflection, rocking curve, SEM, TEM, and surface profiler. It was also found that such a double buffer could lead to a very smooth surface in the YBCO layer.published_or_final_versio
