| 1 | Shoot and root traits in drought tolerant maize(Zea mays L.) hybrids显示文摘This study aimed to investigate the differences in shoot and root traits, and water use and water use efficiency(WUE) in drought tolerant(DT) maize(Zea mays L.) hybrids under full and deficit irrigated conditions. A two-year greenhouse study was conducted with four hybrids(one conventional hybrid, 33D53AM, two commercial DT hybrids, P1151 AM, N75H, and an experimental hybrid, Exp HB) grown under two water regimes(I_(100) and I_(50), referring to 100 and 50% of evapotranspiration requirements). Under water stress, the hybids P1151 AM, N75, and Exp HB showed more drought tolerance and had either greater shoot dry weight or less dry weight reduction than the conventional hybrid(33 D53 AM). However, these three hybrids responded to water stress using different mechanisms. Compared with the conventional hybrid, the two commercial DT hybrids(P1151 AM and N75H) had a smaller leaf area, shoot dry weight, and root system per plant. As a result, these hybrids used less water but had a higher WUE compared with the conventional hybrid. In contrast, the experimental hybrid(ExpHB) produced more shoot biomass by silking stage at both irrigation levels than all other hybrids, but it had relatively lower WUE. The hybrids demonstrated different drought response mechanisms that may require different irrigation management strategies. More investigation and validation are needed under field conditions and in different soil types. | ZHAO Jin XUE Qing-wu Kirk E Jessup HOU Xiao-bo HAO Bao-zhen Thomas H Marek XU Wen-wei Steven R Evett Susan A O'Shaughnessy David K Brauer | 2018 | Journal of Integrative Agriculture2018，17，5： | 3 |
| 2 | Do statins reduce hepatitis C RNA titers during routine clinical use?显示文摘AIM: To compare hepatitis C virus (HCV) titers in patients with chronic hepatitis C with and without exposure to 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins).METHODS: Medical records were reviewed for 6463 patients with documented HCV infection at a single center between March 2004 and September 2006. Patients with confi rmed viremia and meeting inclusion criteria were assigned to one of three groups: Group A (n = 50), dyslipidemic patients with statin usage during HCV RNA polymerase chain reaction (PCR) determination; Group B (n = 49), dyslipidemic patients with prior or future statin usage but not at the time of HCV RNA PCR determination; and Group C (n = 102), patients without statin usage during the study period. The primary analysis explored the effect of statin therapy on HCV viremia. Secondary analyses assessed class effect, dose response, and effect of other lipid-lowering therapies on HCV viral titers.RESULTS: Median HCV RNA titers did not signif icantly differ among the three groups (Group A: 4 550 000 IU/mL, Group B: 2 850 000 IU/mL, Group C: 3 055 000 IU/mL).For those subjects with longitudinal assessment of HCV viremia prior to and while on statins, there were no signif icant differences between pre- and post-HCV viral titers. Additionally, no differences in HCV titers were observed at any dose level of the most prescribed statin, simvastatin. However, hypertriglyceridemia independently correlated with HCV titers, and niacin exposure was associated with signif icantly lower viral titers (P < 0.05).CONCLUSION: There was no apparent effect of statins on HCV viral replication in this analysis. Further investigation is warranted to explore the possible antiviral properties of triglyceride-lowering agents and their potential role as adjuncts to standard HCV therapy. | Kimberly A Forde Connie Law Rose O’Flynn David E Kaplan | 2009 | World Journal of Gastroenterology2009，15，40： | 2 |
