1Expression of an(E)-β-farnesene synthase gene from Asian peppermint in tobacco affected aphid infestation显示文摘Aphids are major agricultural pests that cause significant yield losses in crop plants each year.(E)-β-farnesene(EβF) is the main or only component of an alarm pheromone involved in chemical communication within aphid species and particularly in the avoidance of predation. EβF also occurs in the essential oil of some plant species, and is catalyzed by EβF synthase. By using oligonucleotide primers designed from the known sequence of an EβF synthase gene from black peppermint(Mentha × piperita), two cDNA sequences, MaβFS1 and MaβFS2, were isolated from Asian peppermint(Mentha asiatica). Expression pattern analysis showed that the MaβFS1 gene exhibited higher expression in flowers than in roots, stems and leaves at the transcriptional level. Overexpression of MaβFS1 in tobacco plants resulted in emission of pure EβF ranging from 2.62 to 4.85 ng d-1g-1of fresh tissue. Tritrophic interactions involving peach aphids(Myzus persicae), and predatory lacewing(Chrysopa septempunctata) larvae demonstrated that transgenic tobacco expressing MaβFS1 had lower aphid infestation. This result suggested that the EβF synthase gene from Asian peppermint could be a good candidate for genetic engineering of agriculturally important crop plants.Xiudao Yu Yongjun Zhang Youzhi Ma Zhaoshi Xu Genping Wang Lanqin Xia 2013The Crop Journal2013,1,1:6

4Analysis of the clinical characteristics and neonatal outcomes of seven cases of pregnancy luteoma discovered incidentally at cesarean section显示文摘Objective:In this study,we summarize the clinical characteristics and neonatal outcomes of patients with pregnancy luteomas that were identified incidentally at cesarean section in our hospital.We also provide a review of the existing literature relating to this condition.Methods:A total of seven cases of pregnancy luteoma were enrolled from our hospital into this retrospective study between March 2013 and February 2018.We then evaluated the clinical characteristics and neonatal outcomes of these patients.Results:All seven patients with pregnancy luteomas found incidentally during Cesarean sections at term as a result of obstetric indications.These masses were unilateral and ranged from 2 to 10 cm in size.All patients underwent partial ovariectomies or oophorocystectomy due to presumptive benign ovarian tumors.Two patients had gestational diabetes and one patient had gestational hypertension.One patient developed hirsutism and a deepened voice.Of the seven newborns,three were girls and four were boys.Physical examinations of the newborns were normal and no virilization was detected among the infant girls.Conclusion:Pregnancy luteoma may be more common than expected.Better strategies are now needed to educate obstetricians about the clinical features of pregnancy luteoma so that they can avoid unnecessary surgery.Junhua Shen Lanlan Tang Genping Huang Xiaoxia Bai Baohua Li Zhengping Wang 2021Gynecology and Obstetrics Clinical Medicine2021,1,2:0
5Mechanism of rhodium(Ⅲ)-catalyzed formal C(sp^3)-H activation/spiroannulation of a-arylidene pyrazolones with alkynes:A computational study显示文摘The rhodium-catalyzed formal C(sp^3)-H activation/spiroannulation of a-arylidene pyrazolones with alkynes was investigated by means of density functional theory calculations. The calculations indicate that the spiroannulation through the proposed C—C reductive elimination is kinetically unfeasible.Instead, the C—C coupling from the eight-membered rhodacycle was proposed to account for the experimental results. The overall catalytic cycle consists of six steps:(1) the keto-enol isomerization;(2)the O—H deprotonation,(3) the C(sp^2)—H bond cleavage;(4) the migratory insertion of alkyne into the Rh—C bond;(5) the C—C coupling and(6) the regeneration of the active catalyst.Hongyan Zou Zhong-Liang Wang Yang Cao Genping Huang 2018Chinese Chemical Letters2018,29,9:0
