We assessed the global incidence, mortality, and disability-adjusted life years(DALYs) associated with various liver diseases, including alcohol-related liver disease(ALD), hepatitis B/C virus infections(hBV or hCV), liver cancer, metabolic dysfunction-associated steatotic liver disease(MASLD), and other chronic liver diseases, from the 2019 Global Burden of Disease study. Additionally, we analyzed the global trends in hepatology research and drug development. From 2000 to 2019, prevalence rates increased for ALD, MASLD and other liver diseases, while they decreased for hBV, hCV, and liver cancer. Countries with a high socio-demographic index(SDI) exhibited the lowest mortality rates and DALYs. The burden of liver diseases varied due to factors like sex and region. In nine representative countries, MASLD,along with hepatobiliary cancer, showed highest increase in funding in hepatology research. Globally, the major research categories in hepatology papers from 2000 to 2019 were cancer, pathobiology, and MASLD. The United States(U.S.) was at the forefront of hepatology research, with China gradually increasing its influence over time. hepatologists worldwide are increasingly focusing on studying the communication between the liver and other organs, while underestimating the research on ALD. Cancer, hCV, and MASLD were the primary diseases targeted for therapeutic development in clinical trials. however, the proportion of new drugs approved for the treatment of liver diseases was relatively low among all newly approved drugs in the U.S., China, Japan, and the European Union. Notably, there were no approved drug for the treatment of ALD in the world.

Chlorfenapyr, an insecticidal pyrrole, was applied to concrete arenas at concentrations of 1. 1, 0.825, 0.55, and 0.275 g of active ingredient [AI]/m^2. Adult Tribolium castaneum （herbst）, the red flour beetle, were exposed for 2, 4, or 8 h at each concentration, then removed and held either with or without food （wheat flour） for 7 days. Survival was assessed when the beetles were removed fi＇om the exposure arenas and daily during the post- exposure period. In the presence of food, survival was high regardless of concentration and the day on which post-treatment survival was assessed, but survival did decrease as the exposure period increased from 4 to 8 h. When the beetles were not given food after exposure, survival at each concentration and exposure period declined during the 1-week post- exposure assessments. This pattern of decrease could be described by linear and non-linear equations. Results show the presence of food material greatly compromised effectiveness of the insecticide, and emphasize the importance of cleaning and sanitation in conjunction with insecticide treatments.

A series of field trials were conducted in a commercial food storage facility to evaluate exposure of stored-product insects to aerosol formulations of synergized pyrethrins and the insect growth regulator methoprene. When adults of Tribolium castaneum （herbst）, the red flour beetle, and Tribolium confusum （Jacqueline DuVal）, the confused flour beetle were exposed with and without a food source to synergized pyrethrin aerosol, there was no difference in adult mortality with respect to availability of food at either 7 or 14 days after exposure （P≥0.05）. however, mortality was lower in T. confusum （40.4% and 79.3% with flour at 7 and 14 days, 38.9% and 84.8% without flour at 7 and 14 days） compared to T. castaneum （96.5% and 99.8% with flour at 7 and 14 days, 91.0% and 98.7% without flour at 7 and 14 days）. Few late-stage larvae and pupae of either species exposed to the pyrethrin aerosol emerged as adults. In tests with methoprene aerosol, adult emergence of exposed 3- and 4-week-old larvae of T. confusum was less than 2%. Only 0.3% of 4-week-old larvae of T. castaneum exposed in open and obstructed areas emerged as adults. Emergence of adults from eggs of Plodia interpunctella （hubner）, the Indianmeal moth, embedded in culture media and exposed to the methoprene aerosol was 13.2%±3.5%. Results show that the aerosols evaluated in our study could give effective control of some of the major storedproduct insect pests in commercial food storage facilities, and may offer an alternative to fumigation.

钢悬链线立管(steel catenary riser,SCR)作为支撑海上平台和其他关键设备的重要组成部分,在极端的海洋环境中长时间服役运行时,其结构完整性和安全性至关重要。为确保SCR立管在恶劣环境下的安全运行,对立管进行共振弯曲疲劳试验研究成为必要的评估标准,同时也为后续立管疲劳寿命预测和失效分析提供基础。针对两种特定型号的SCR立管,推导并求解不同约束条件下的共振系统的固有频率与振型函数,分析管道长度、管道壁厚、偏心块和配重块质量对共振系统固有频率的影响;在此基础上开展不同特定工况下的全尺寸共振弯曲疲劳试验,同时对SCR立管在全尺寸共振弯曲疲劳试验系统中不同跨距及内压的振动响应特性进行了模拟。结合理论分析、有限元计算和共振弯曲疲劳试验结果,发现管道长度和两端的配重约束是影响共振系统1阶固有频率的重要参数,特别是在管道长度较短和壁厚较薄的情况下,影响更为显著。此外,注水加压和跨距增加会降低共振系统的固有频率,支撑跨距越短,系统的固有频率越大。分析所得结果为SCR立管的共振弯曲疲劳试验系统结构设计和试验方案优化提供了重要的参考依据。

Aerosol insecticides may provide an alternative to fumigants for control of the Indianmeal moth, Plodia interpunctella （hübner）, the Indianmeal moth, a major insect pest of stored processed food. In this study, eggs and larvae （5th instars） ofP. interpunctella were exposed to aerosol applications of the pyrethroid esfenvalerate and insect growth regulator methoprene, alone and in combination, in open and obstructed positions inside small sheds. When larvae were exposed to methoprene alone, adult emergence from those exposed larvae was 7.1% ± 1.5%. In contrast, adult emergence was 92.5% ± 3.5% when larvae were exposed to esfenvalerate alone. When eggs were exposed to methoprene, adult emergence of those exposed eggs was approximately 75%; however, when eggs were exposed to esfenvalerate, adult emergence was approximately 35%. In the combination treatment of methoprene plus esfenvalerate at their respective label rates, adult emergence following larval exposure was 0.91% ±0.61% compared to 16.3% ± 9.6% when eggs were exposed. Based on our results, methoprene alone is highly effective in reducing adult emergence after larval exposure. however, it is not as effective on eggs as esfenvalerate. A combination treatment of esfenvalerate plus methoprene could be used to control eggs and the wandering-phase larval stages ofP. interpunctella. An economic risk analysis also supports a strategy of combining methoprene and esfenvalerate.

Long-grain rice cultivars Cocodrie, Wells, and XP 723 grown in three locations （hazen, MO; Essex and Newport, AR, USA）, and medium-grain rice cultivars Bengal and XP 713 grown in two locations （Jonesboro and Lodge Corner, AR, USA）, were harvested and assayed for susceptibility to Rhyzopertha dominica （F.）（Coleoptera： Bostrichidae）, the lesser grain borer, and Sitophilus oryzae （L.）（Coleoptera： Curculionidae）, the rice weevil, on rice held at 27℃, 57% and 75% relative humidity （Rh）. Separate samples from the same harvest lots were also analyzed for the physical characteristics of brown rice yield, percentage whole kernels and kernel thickness. Progeny production and feeding damage of R. dominica were significantly different among long-grain cultivars within two of the three locations （P 〈 0.05）, but not for location or Rh （P ≥ 0.05）, while progeny production of S. oryzae was different among cultivars, location, and Rh （P 〈 0.05）. On medium-grain rice, both cultivar and location were significant for progeny production of R. dominica, but not Rh, while cultivar and Rh were significant for progeny production of S. oryzae, but not location. On both rice types, feeding damage of R. dominica followed the same trends and was always strongly positively correlated with progeny production （P 〈 0.05）, but for S. oryzae there were several instances in which progeny production was not correlated with feeding damage （P ≥ 0.05）. Physical characteristics of both rice types were statistically significant （P 〈 0.01） but actual numerical differences were extremely small, and were generally not correlated with progeny production of either species. Results indicate that the location in which a particular rice cultivar is grown, along with its characteristics, could affect susceptibility of the rice to R. dominica and S. oryzae.
