Study on Active Oxygen Quantum Yield,Insecticidal Activities and Stability of Diphenylthiophene

引用

Agricultural Sciences in China 2007年第4期6卷 458-465页

作者： CHEN xiao-jun xu han-hong WANG Yu-jian HU Shan ZhanG Zhi-xiang ZhanG Yao-mou Key Laboratory of Pesticide and Chemical Biology Ministry of Education/Laboratory of Insect Toxicology South China Agricultural University Guangzhou 510642 P.R.China

Active oxygen quantum yield, insecticidal activities and stability of diphenylthiophene were studied for the first time. The results showed that maximum diphenylthiophene absorbency variety was 0.438 after irradiation for 280 min and that of α- terthienyl （α-T） was 0.480 after irradiation for 200 min with UV. LCs0 values ofdiphenylthiophene and α-T against 3rd instar larvae ofAedes albopictus were 9.18 × 10^-3 and 9.69× 10^-4 μg mL^-1 when treated for 24 h, respectively. LC50 values of the two chemicals against the 3rd instar larvae of Plutella xylostella were 267.87 and 222.22 μg mL^-1 when treated for 24 h, respectively. The half lives of diphenylthiophene and α-T in methanol were 113.62 and 10.65 h. Difference between quantum yield of diphenylthiophene and α-T was not significant and they all possessed high toxicity to Aedes albopictus and Plutella xylostella, but diphenylthiophene was more stable than α-T. It could be concluded that diphenylthiophene has overcome the deficiency of photoactivated insecticides which degraded quickly in the environment and could not be applied on the field. Diphenylthiophene could kill the insects and accelerate the degradation rate of triazophos. The benefits of diphenylthiophene can be further exploited and applied on the field.

Insulin treatment has many cutaneous alterations and skin-related adverse effect,lipohypertrophy(LH)is the commonest among them.[1]LH has the definition with a tumor-like lump,visible and touchable,adipose tissue at the site of insulin injection.[2]It might result from the lipogenic effect of repeated insulin exposure.[3,4]Injecting insulin into the tissue with LH weakens insulin physiological function,and leads to a resulting excess glucose exposure,glycemic modifiability,and an increased risk of hypoglycemia.[5]Unfortunately,there is limited information about the pathophysiology of LH in insulin *** a result,reports of prevalence,clinical consequence,and pathogenesis are needed.

针对多目标混合算子进化算法中各算子有效选择的自适应问题,提出一种基于双重贡献分配的多目标混合算子进化算法(DCA-MOEA/D).首先,将两种现有的进化算子与两种基于方向引导的差分进化组成算子池,每代个体以轮盘赌的方式从中选择一种进化算子产生子代;然后,根据子代的表现,结合两种方法为各算子分配贡献值,从而确定算子的选择概率;接着,引入外部归档集,根据非支配关系与拥挤度策略对其进行维护;最后,将整个进化过程划分为5个阶段,以达到算子选择中“探索”与“探究”之间的平衡.以IGD与HV为性能评价指标,通过与其他4种多目标进化算法在23个测试函数上的对比,验证所提出算法在收敛性和分布性上的显著优势.

Background The effect of urbanization on the morbidity of hepatitis A remains unclear. We aimed to estimate the association between various urbanization-related indices and hepatitis A morbidity in *** Data on the annual morbidity of hepatitis A, urbanization-related measures (i.e., gross domestic product per capita, the number of hospitalization beds per 1000 persons, illiteracy rate, tap water coverage, motor vehicles per 100 persons, population density, and the proportion of arable land), and meteorological factors in 31 provincial-level administrative divisions of Chinese mainland during 2005–2018 were collected from the National Population and Health Science Data Sharing Platform, China Statistical Yearbooks, and the China Meteorological Data Sharing Service System, respectively. Generalized linear mixed models were applied to quantify the impacts of different urbanization-related indices on the morbidity of hepatitis A in China after adjusting for *** A total of 537,466 hepatitis A cases were reported in China during 2005–2018. The annual morbidity had a decline of 79.4% from 5.64 cases to 1.16 cases per 100,000 people. There were obvious spatial variations with higher morbidity in western China. Nationally, gross domestic product per capita and the number of hospitalization beds per 1000 persons increased from 14,040 to 64,644 CNY and from 2.45 to 6.03 during 2005–2018, respectively. The illiteracy rate decreased from 11.0 to 4.9%. Gross domestic product per capita [relative risk (RR) = 0.96, 95% confidence interval (CI): 0.92–0.99], and the number of hospitalization beds per 1000 persons (RR = 0.79, 95%CI: 0.75–0.83) were associated with the declined morbidity of hepatitis A. By contrast, the increased morbidity of hepatitis A was linked to the illiteracy rate (RR = 1.04, 95%CI: 1.02–1.06). Similar influential factors were detected for children and adults, with greater effects witnessed for *** People in the western

Background Transradial coronary intervention （TRI） introduces injury to the radial artery （RA） which will affect repeat transradial coronary procedure and the quality as a bypass conduit. We sought to compare the early radial injury after TRI between first-TRI and repeat-TRI by ultrasound biomicroscopy （UBM）. Methods A total of 1116 patients who underwent the transradial coronary procedures were enrolled. The patients depending on whether for the first time to accept transradial coronary procedure were divided into first-TRI group and repeat-TRI group. The RA was examined by UBM before and one day after the procedure. Results Compared with first-TRI group, the mean RA diameter of repeat-TRI one day after the procedure decreased significantly （P 〈0.05）. In first-TRI group, the mean RA diameter was （2.32±0.53） and （1.93±0.57） mm before procedure and one day after the procedure respectively （P 〈0.05）. In repeat-TRI group, the mean RA diameter was （2.37±0.51） and （1.79±0.54） mm before procedure and one day after the procedure, respectively （P 〈0.01）. Compared with first-TRI group, the mean RA diameter was reduced significantly in repeat-TRI group one day after the procedure （P〈0.05）. The early radial injuries and intimal thickening were compared between first-TRI and repeat-TRl. The mean intima-media thickness of RA was （,0.24±0.13） mm and （0.59±0.28） mm before procedure and one day after the procedure in first-TRI group. The mean intima-media thickness of RA was （0.29±0.16） mm and （0.68±0.32） mm before procedure and one day after the procedure in repeat-TRI group. Compared with first-TRI group, the mean intimal thickening was increased significantly in repeat-TRI group one day after the procedure （P〈0.05）. Intimal dissection, stenosis and occlusion were all significantly greater in repeat-TRI RAs （P 〈0.05）. Linear regression analysis revealed that diameter, repeated TRI procedure and PCI procedure were the independent predictors of intimal thickening. Conclusions RA ea
