| 1 | Genetic contribution of foreign germplasm to elite Chinese soybean (Glycine max) cultivars revealed by SSR markers显示文摘Simple sequence repeats (SSR) marker analysis, combined with pedigree analysis, was car- ried out to trace the genetic constitutes of Suinong 14 and Hefeng 25 in assessing the contribution of for- eign germplasm to those elite cultivars. The overall goal is to accumulate information for further effective utilization of foreign germplasm in Chinese soybean breeding programs. SSR clustering results indicated that the genetic base of elite Chinese soybean culti- vars, including Suinong 14 and Hefeng 25, were broadened and enhanced via introduction of Amsoy from the U.S. and Shishengchangye from Japan. The pedigree analysis showed a very high coefficient of parentage between Shishengchangye and Hefeng 25, between Shishengchangye and Suinong 14, and between Amsoy and Suinong 14. The genetic simi- larity between Suinong 14 and Hefeng 25 was 60.58%. Among 20 linkage groups, more genomic regions were transferred from Hefeng 25 to Suinong 14 in linkage group (LG) I, L and C2 than other LGs. Among the unique alleles of foreign parents, five specific loci in Amsoy were transferred to Suinong 14, and three loci from Shishengchangye to Suinong 14. Some SSR loci were proved to be correlated with phenotypes: two loci for seed size introgressed from Shishengchangye to Suinong 14, and one locus forprotein content from Amsoy to Suinong 14. These results indicate that the two foreign parents might have important contributions in the development of Suinong 14 and Hefeng 25. | QIN Jun CHEN Weiyuan GUAN Rongxia JIANG Chengxi LI Yinghui FU Yashu LIU Zhangxiong ZHANG Mengchen CHANG Ruzhen QIU Lijuan | 2006 | Chinese Science Bulletin2006，51，9： | 4 |
| 2 | Fatal spontaneous rupture of common iliac artery associated with fibromuscular dysplasia显示文摘A previously healthy 25-year-old man with no known risk factors was presented at the emergency room with a 3 h history of abdominal and loin pain.Physical examination and lab data showed no specific findings except tenderness,slight white cell count elevation and decreased haemoglobin level.The patient’s condition deteriorated over the following hours and he died despite resuscitation attempts.Autopsy revealed a 2.5-cm longitudinal tear in the intima of the right common iliac artery,which formed a thrombosed false lumen extending to the abdominal aorta proximally and to the left common iliac artery.Histopathologic examination revealed the characteristic changes of fibromuscular dysplasia(FMD).FMD involving the common iliac arteries is extremely rare;only six cases have been reported previously,and only two of those included forensic findings.The presented case is the first case of FMD with intimal tearing in the right common iliac artery,with propagation to the left common iliac artery and abdominal aorta.When a previously healthy young adult without hypertension or other risk factors presents with acute abdominal and loin pain,systemic vascular disease should be on the list of differential diagnoses.Careful and complete evaluation of multiple arteries can be critical. | Xiang Xu Mengchen Tsai Ning Xiao Xiaohui Tan Fu Zhang Yangeng Yu Qi Wang Weibing Xie Huijun Wang Dongri Li | 2019 | Forensic Sciences Research2019，4，4： | 1 |
| 3 | Au^(δ-)-O_(v)-Ti^(3+):Active site of MO_(x)-Au/TiO_(2) catalysts for the aerobic oxidation of 5-hydroxymethylfurfural显示文摘Despite wide applications of noble metal-based catalysts in 5-hydroxymethylfurfural(HMF)oxidation,promoting the catalytic performance at low loading amounts still remains a significant challenge.Herein,a series of metal oxide modified MO_(x)-Au/TiO_(2)(M=Fe,Co,Ni)catalysts with low Au loading amount of 0.5 wt%were synthesized.Addition of transition metal oxides promotes electron transfer and generation of the Au^(δ-)-O_(v)-Ti^(3+)interface.A combination study reveals that the dual-active site(Au^(δ-)-O_(v)-Ti^(3+))governs the catalytic performance of the ratedetermining step,namely hydroxyl group oxidation.Au^(δ-) site facilitates chemisorption and activation of O_(2) molecules.At the same time,O_(v)-Ti^(3+) site acts as the role of“killing two birds with one stone”:enhancing adsorption of both reactants,accelerating the activation and dissociation of H_(2)O,and facilitating activation of the adsorbed O_(2).Besides,superoxide radicals instead of base is the active oxygen species during the rate-determining step.On this basis,a FDCA yield of 71.2% was achieved under base-free conditions,complying with the“green chemistry”principle.This work provides a new strategy for the transition metal oxides modification of Au-based catalysts,which would be constructive for the rational design of other heterogeneous catalysts. | Weiyao Yang Mengchen Fu Chenyu Yang Yiwen Zhang Chun Shen | 2023 | Green Energy & Environment2023，8，3： | 0 |
