    Abstract Athetis lepigone (Möschler) is a new insect pest that feeds on corn seedlings in summer corn region of China. It is an omnivorous insect, which not only infests corn, soya bean, peanut and other crops, but also feeds on fallen and decaying leaves of some crops and weeds. Effects of host plants, corn, cotton, peanut, wheat and soya bean, on larval and pupal development and survival, and the fecundity of adults of A. lepigone were studied under laboratory conditions. The developmental time from egg to adult was the shortest (30.78 days) on germinating wheat kernels and the longest (40.13 days) on corn leaves. Larval survival was the highest (80%) on germinating wheat kernels and lowest (55%) on soya bean leaves. Hatching rate was the highest (92.98%) where eggs were oviposited by the females developed from larvae that were fed on germinating wheat kernels. Similarly, fecundity was the greatest on germinating wheat kernels (337), while the lowest fecundity (145) was observed on cotton leaves. The highest intrinsic rate of increase (0.22) and net reproduction rate (181.39) were found on germinating wheat kernels. Germinating wheat kernels were recognized as the most suitable host plant for A. lepigone because of the shortest developmental period, highest survival and highest fecundity. The results correspond with the field habits of A. lepigone and clearly show differences in development and adaptability on the five tested host plants. The findings will serve as baseline information to better understand the biology of the pest, which can be utilized in an effective management programme.

    Abstract Heavy metal pollution in fine particulate matter (PM₂.₅) is a serious environmental and health concern in China, particularly during winter. Here, we detected 40 elements in 24 h integrated daily PM₂.₅ samples collected in January 2014 from three typical Chinese metropolises (Beijing, Changchun, and Chengdu) to reflect elemental spatial variations, local sources, and regional transport. The measured elemental concentrations in Changchun were 11.1% and 48.4% higher than those in Beijing and Chengdu, respectively. Thus, PM₂.₅ from Changchun exhibited high levels and diversity in the elemental profile (characterized by high concentrations of industrial emission elemental markers). The results of elemental ratios and Pb isotopes proved that, except for a coal combustion source, vehicular emissions contributed more to PM₂.₅ heavy metals in Beijing than in the other two cities; Changchun PM₂.₅ elements received large contributions from industrial sources, including iron and steel manufacturing, and automobile industry. Moreover, crustal dust from long-range transport of regional air masses from the northwest regions of China played a crucial role in determining elemental levels in Beijing and Changchun, accounting for more than 50% of source intensity. However, a specific dominant source was not determined in Chengdu; the contribution of anthropogenic dust, mainly from construction activities, needs to be paid attention in Chengdu eastern area. This study contributed to enhancing our understanding of elemental spatial distribution characteristics and sources and to setting more judicious standards and strategies for PM₂.₅ bound heavy metals in China.

    Abstract The Asian corn borer, Ostrinia fumacalis (Guenée), is a major pest of maize in China. Transgenic Bt maize could provide an effective way to control this pest. However, the potential of resistance evolution has been documented in the laboratory—a Cry1Ab-resistant strain of Asian corn borer (Asian corn borer-AbR) could survive well on two Bt maize events, that is, MON810 and Bt11. Pyramided transgenic crops with multiple dissimilar Bt insecticidal proteins offer a superior route for pests control compared with that with one Bt single gene. In this study, two novel transgenic Bt maize events (N30 and V3), which contained a fused gene cry1Ab/cry2Aj and cry1Ab/vip3DA, respectively, were evaluated for their efficacy on protection against Cry1Ab-susceptible Asian corn borer (Asian corn borer-BtS) as well as their potential for dealing with the Asian corn borer-AbR. In laboratory bioassay, no neonate larvae of Asian corn borer-BtS fed on the whorl leaves, tassels, husks, silks, and kernels of N30 and V3 could survive at 96 h after infestation. In contrast, only 2.0–8.7% larvae died as they fed on non-Bt maize tissues. As Asian corn borer-AbR neonate larvae fed on N30 and V3 silks and kernels, 95.0% even more larvae were killed at 96 h after infestation, and all died at 168 h after infestation, while 10.0–11.67% larvae survived on non-Bt control. In the field test under artificial infestation at middle whorl leaf and silking stages of maize, there were no significant leaf, silk, and stalk damage on Bt maize plants by comparison with severe leaf feeding, stalk born, and ear damage in control. In addition, the expression profiles of a fused protein of Cry1Ab/Cry2Aj or Cry1Ab/Vip3DA in different tissues of N30 and V3 were also confirmed. In conclusion, it is clear that both Bt maize events (N30 and V3) show great potential for protecting maize from attack by Asian corn borer that has resistance to Cry1Ab protein.

    Abstract Salubrinal is a selective inhibitor of endoplasmic reticulum (ER) stress and affords remarkable protection to cardiomyocytes. By studying the structure-activity relationship (SAR) of salubrinal, it was found that modification of the quinoline ring terminus and thiourea unit could confer the compound PP1-24 with markedly enhanced cardioprotective activity (EC50 ≤ 0.3 μM) that is 50-fold more potent than salubrinal. Comparative molecular field analysis (CoMFA) was performed using the obtained biological data and resulted in a statistically significant CoMFA model with high predictive power (q2 = 0.741, r2 = 0.991).

    Abstract Objective: To study the genomic abnormality underlying the blast crisis of chronic myeloid leukemia(CML).
    Methods: 15 CML patients in blast crisis (BC), 3 in accelerated phase (AP) and 20 in chronic phase (CP) were analyzed by conventional cytogentics, comparative genomic hybridization (CGH) and dual color chromosomal painting.
    Results: Philadelphia (Ph) chromosome was identified in every case studied. Only 5 among 20 CP patients had additional abnormalities while 12 out of 14 patients with disease progression (BC + AP) showed extra numerical and/or structural chromosmal aberrations. Cytogenetically, the most common chromosome gains during BC and AP were double or triple Ph chromosome(5/14), trisomy 8(5/14), trisomy 7(1/14) and 17 (1/14). Three cases showed the same region being involved in translocations t(1;17)(q12-21;q10), t(1;10) (q12-21;q26) and t(1;11)(q12-21;p15). CGH analysis detected genetic imbalances in 8 cases. In one case, a very complex chromosmal translocation del(3), del(6)(q13-21), der(6)t(17;3;6), der(17)t(6;17) was characterized by chromosomal painting.
    Conclusion: We find that the combined use of CGH, chromosomal painting, and classic cytogenetic analysis allows a better evaluation of the genomic aberration involved in CML blastic transformation, and offers new directions for its further molecular investigation.

    Abstract Objectives: The present study assesses clinical outcomes in patients from the Potential Angina Class Improvement From Intramyocardial Channels (PACIFIC) trial of percutaneous transmyocardial revascularization (PTMR) who had previously been considered "no-option," but who subsequently underwent percutaneous coronary intervention (PCI) for continuing symptoms.
    Background: Patients with advanced symptomatic coronary artery disease who are not candidates for coronary artery bypass grafting (CABG) or PCI comprise an important group, for which no established treatment is currently available. These patients have been described as having "no option," and are currently targeted for various experimental therapies. One such proposed therapy, PTMR, was recently examined in the PACIFIC trial. A subgroup of patients in this trial subsequently underwent PCI, although to initially qualify for the study they had previously been considered as unsuitable for PCI and as having "no option." The therapeutic benefit of PCI for patients of this type is unknown.
    Methods: A retrospective analysis was performed on data obtained from all subjects of the PACIFIC study who underwent PCI within the 12-month follow-up period.
    Results: Ten subjects originally randomized to PTMR and 11 subjects from the medical treatment group underwent PCI. Most had undergone at least one prior PCI and at least one CABG, and there was a high prevalence of cardiovascular risk factors. Despite excellent immediate procedural success, PCI resulted in only modest, statistically nonsignificant increases in mean exercise duration, small improvements in angina status, and no significant improvements in quality of life.
    Conclusions: These data suggest that PCI provides only marginal-if any-symptomatic benefit in these patients.
