IBA concentrations ranging from 0 to 500 mg/L were applied to cuttings of semi-hardwood and hardwood in a split-plot Randomized Complete Block Design experiment. The findings indicated that at four weeks after planting, both cutting types started to produce calluses, and at eight weeks, roots started to sprout. For both kinds of cuttings, 400 mg/L was the ideal IBA concentration, resulting in the greatest rooting percentages of 70% for hardwood cuttings and 83.3% for semi-hardwood cuttings. In all treatments, semi-hardwood cuttings showed consistently better rootability than hardwood cuttings. At 400 mg/L IBA, the semi-hardwood cuttings exhibited the largest mean number of roots (8.33). For root length, dry weight, and number of roots, there were no statistically significant variations between treatments. Hardwood cuttings, on the other hand, demonstrated a significant difference in each of these parameters between the control and all IBA treatments;at 400 mg/L IBA, the highest mean number of roots (7.00) was also seen. For both cutting types, the rooting percentage increased from 0 mg/L to 400 mg/L IBA, then decreased at 500 mg/L, indicating an upper limit to the positive effects of IBA. The rooting percentage of semi-hardwood cuttings showed a notable trend, rising from 3.3% (control) to 83.3% (400 mg/L) and then falling to 63.3% at 500 mg/L. These results offer information about the vegetative propagation of Synsepalum dulcificum, showing that the best way to root is using semi-hardwood cuttings treated with 400 mg/L IBA. Through the development of effective multiplication techniques, miraculous fruit’s potential for large-scale cultivation and a range of uses in the food and pharmaceutical industries is supported.展开更多

The purpose of this study was to determine whether reverse left ventricular(LV) remodeling and symptomatic benefit from CRT were sustained at 12 months, and if so, in what proportion of patients this occurred. Methods and Results -Serial Doppler echocardiograms were obtained at baseline and 6 and 12 months after CRT in 228 patients enrolled in the Multicenter InSync Randomized Clinical Evaluation(MIRACLE) trial. Measurements were made of LV end-diastolic(EDV) and end-systolic(ESV) volumes, ejection fraction, LV mass, severity of mitral regurgitation(MR), peak transmitral velocities during early(E wave) and late(A wave) diastolic filling, and myocardial performance index. At both 6 and 12 months, respectively, CRT was associated with reduced LV EDV(P< 0.0001 and P=0.007) and LV ESV(P< 0.0001 and P< 0.0001), improved ejection fraction(P< 0.0001 and P< 0.0001), regression of LV mass(P=0.012 and P< 0.0001), and reduced MR(P< 0.0001 and P< 0.0001). LV filling time, transmitral E/A ratio, and myocardial performance index all improved at 12 months compared with baseline(P< 0.001, P=0.031, and P< 0.0001). Reverse LV remodeling with CRT occurred in more patients at 6 than at 12 months(74%versus 60%, respectively; P< 0.05) and was greater in patients with a nonischemic than an ischemic etiology. Conclusions -Reverse LV remodeling and symptom benefit with CRT are sustained at 12 months in patients with New York Heart Association class III/IV heart failure but occur to a lesser degree in patients with an ischemic versus a nonischemic etiology, most likely owing to the inexorable progression of ischemic disease.展开更多

This has been the longest growth slowdown since the country adopted the reform and opening-up policy in 1978. In a recent article in the Reference News daily,Justin Yifu Lin,an economics professor at Peking University and former World Bank chief economist and senior vice president, attributed the slowdown mainly to external factors. Lin said China can still achieve a relatively fast growth of 7 percent or more by fully tapping its advantages as a latecomer. Edited excerpts of the article follow：展开更多
