The Role of CNTs in Promoting Hybrid Filler Networking and Synergism with Carbon Black in the Mechanical Behavior of Filled Polyisoprene

The filler networking process promoted by multiwalled CNTs is studied in neat and CB-filled poly(1,4-cis-isoprene) matrices. TEM analysis, tensile, dynamic-mechanical, and electrical measurements reveal that the CNTs form a filler network at low concentration in neat PI and a continuous hybrid filler network at a lower CNT concentration in the presence of CB, with a remarkable increase of the nonlinear dynamic- mechanical behavior of the nanocomposites at low deformation. A synergistic effect between CB and CNTs is demonstrated. The addition of CNTs to the CB-filled PI matrix leads to initial modulus values much larger than those calcu- lated by simple addition of the two initial moduli of the composites containing only CB and only CNTs, respectively

Respiratory Training Late After Fontan Intervention: Impact on Cardiorespiratory Performance

Fontan palliation allows patients with â\u80\u9csingle ventricleâ\u80\u9d circulation to reach adulthood with an acceptable quality of life, although exercise tolerance is significantly reduced. To assess whether controlled respiratory training (CRT) increases cardiorespiratory performance. 16 Adolescent Fontan patients (age 17. 5 ± 3.8 years) were enrolled. Patients were divided into CRT group (n = 10) and control group (C group, n = 6). Maximal cardiopulmonary test (CPT) was repeated at the end of CRT in the CRT group and after an average time of 3 months in the C group. In the CRT group a CPT endurance was also performed before and after CRT. In the CRT group there was a significant improvement in cardiovascular and respiratory response to exercise after CRT. Actually, after accounting for baseline values, the CRT group had decreased breathing respiratory reserve (â\u88\u92 15, 95% CI â\u88\u9222.3 to â\u88\u92 8.0, p = 0.001) and increased RR peak (+ 4.8, 95% CI 0.7â\u80\u938.9, p = 0.03), VE peak (+ 13.7, 95% CI 5.6â\u80\u9321.7, p = 0.004), VO2of predicted (+ 8.5, 95% CI 0.1â\u80\u9317.0, p = 0.05), VO2peak (+ 4.3, 95% CI 0.3 to 8.2, p = 0.04), and VO2workslope (+ 1.7, 95% CI 0.3â\u80\u933.1, p = 0.02) as compared to the control group. Moreover, exercise endurance time increased from 8.45 to 17.7 min (p = 0.01). CRT improves cardiorespiratory performance in post-Fontan patients leading to a better aerobic capacity
