Appraisement of Effect of BACTIVEC and GRISELESF for Killing Mosquito Larvae with the Locale and Laboratory Tests

Zhongguo meijie shengwuxue ji kongzhi zazhi (2002)

Zhao Yan

Objective: To appraise the effect of BACTIVEC and GRISELESF for killing mosquito larvae and study the best way to appraise. Methods: The effect of two biotic pesticides for killing mosquito larvae was tested by the locale and laboratory tests, To observe the mosquito larvae and pupae density degression rate. Results:In the locale, after spraying 3rd days, for BACTIVEC 5 ml/m 2, the density degression rate of the mosquito larvae and pupae was 97.5 % and 92.7 %. After 5th,7th, and 15th day, the density degression rate was usual kept up over 97%. Another, for GRISELESF,10 ml/m 2, after 3rd day, the density degression rate of mosquito larvae was 96%,and the rate of pupae was only 20%. But 5 to 15 days later, the effect of control pupae by GRISELESF was approached to BACTIVEC. The results of labortory was similar to locale. Conclusion: The effects of both biotic pesticides were noticeable to control the mosquito larvae,and the former outbalanced the latter.

Expression of tumor necrosis factor alpha and transforming growth factor-beta 1 in decidua

Guangxi Medical Journal (2009)

Zhao Yan

Objective To study the anti-early pregnancy mechanism of Mifepristone by investigating the expression of tumor necrosis factor alpha(TNF-α) and transforming growth factor-beta 1(TGF-β1) in decidua of early pregnancy.Methods Expression of TNF-α and TGF-β1 in decidua of early pregnancy were measured by using immunohistochemical assay(two-step) in 3 groups(drug abortion,n=30),group 2(induced abortion+ misoprostol,n=20) and group 3(induced abortion,n=20).Results The expression of TNF-α and TGF-β1 in group 1 were significantly higher than the other groups(P0.05).Conclusion Mifepristone can prevent pregnancy by increasing the TNF-α and TGF-β1 in decidua of early pregnancy.

Soil Organic Nitrogen Indirectly Enhances Pepper-Residue-Mediated Soil Disease Suppression through Manipulation of Soil Microbiome

Agronomy (2022)

Shan Hong Hongling Jv Xianfu Yuan Jianjian Geng Beibei Wang

Banana Fusarium wilt-suppressive soils are effective against pathogen invasion, yet soil physicochemical factors responsible for conducive or suppressive behavior have not been reported. Here, we investigated the changes in banana biomass, disease incidence (DI), soil culturable microbes and physicochemical properties by incorporating pepper and banana residues into conducive and suppressive soils. Before the incorporation of any residues, the suppressive soil significantly increased banana biomass and decreased DI compared to the conducive soil. The biomass of the suppressive soil was significantly higher than that of the conducive soil after the incorporation of either pepper or banana residues. Compared with the control (CK), the incorporation of pepper residues to both soils significantly reduced DI, while banana residues had the opposite effect. Additionally, both conducive and suppressive soils supplemented with pepper residues significantly reduced the amounts of culturable Fusarium oxysporum and increased the amounts of beneficial Pseudomonas and Bacillus. The pepper residue extracts significantly inhibited the growth of F. oxysporum mycelium. Soil alkali-hydrolyzable nitrogen (AN) responded most strongly to residue application to suppressive soil. The AN factor was significantly and positively correlated with banana biomass; however, there was no direct and significant negative correlation with DI. Further analysis of the results showed that elevated AN content could stimulate the amounts of culturable Bacillus in the soil, and Bacillus antagonized the proliferation of pathogen and thus indirectly and effectively reduced banana DI. In conclusion, soil AN content can indirectly improve the disease suppression ability of pepper-residue-mediated suppressive soil by manipulating the soil microbiome.

Application of Cre/lox Site-specific Recombination System in Transgenic Plants

Zhongguo shengwu huaxue yu fenzi shengwu xuebao (2010)

Zhao Yan

Site-specific recombination system, which consists of recombinase and the related-recombinase recognizing short DNA sequences, has been developed into genetic manipulation tool by two-component interaction for the goal of targeted integration and precise excision of DNA fragment. Cre/lox recombination system, which belongs to the family of site-specific recombination system including Cre/lox, FLP/frt, R/RS and Gin/gix, is one of the best characterized and most widely used system. Cre/lox system consists of Cre recombinase and 34 bp lox sites, which initially was applied in basic transgenic animal research such as gene knockout, gene activation and gene translocation. With the rapid development of biotechnology, Cre/lox system has been investigated to transgenic plants and makes impressive progress in recent years. In this paper, the advances of Cre-lox system are reviewed, providing insight of site-specific integration, site-specific excision and plant chloroplast transformation to construct environmental friendly plant genetic transformation system with high-level foreign gene expression.

Protective Effect of Trimetazidine on Rat Mitochondria with Myocardial Ischemia Reperfusion Injury

Chinese Journal of Arterial Lerosis (2005)

Zhao Yan

Aim To study the protective effect of trimetazidine (TMZ) on mitochondria of myocardial ischemia and ischemia reperfusion injury and its mechanism. Methods Totally 50 SD rats were randomly divided into 4 groups: the pseudooperation group, the saline group and the TMZ treated groups (5 mg/kg and 10 mg/kg). In the pseudooperation group the coronary artery was not ligated but the chest was opened, the other groups were the model of myocardial ischemia reperfusion injury(RI). The level of malonaldehyole(MDA), superoxide dismutase (SOD), glutathione (GSH), glutathione peroxidase (GSH-Px) and the accumulation of Ca 2+ in mitochondria of myocardial were detected at ischemia 30 min and reperfusion 40 min. The myocyte ultrastructure was also observed by electron microscope in 4 groups. Results Compared with the pseudooperation group, the MDA and total Ca 2+ were significantly higher and the SOD, GSH, GSH-Px were significantly lower in saline group and treated groups. Compared with the saline group, the MDA and total Ca 2+ was significantly lower and the SOD, GSH, GSH-Px were significantly higher in treated group. The ultrastructure changes of myocardium ulder electron microscope showed that the damage degree of mitochondria is slighter in TMZ treated groups than in saline group. Conclusions TMZ could significantly reduce the injury of lipid peroxidation of myocardial mitochondrial induced by ischemia and ischemia reperfusion. The mechanism may be that TMZ could increase the content of GSH and the acvitity of SOD and GSH-Px, and enhance its antioxidant production. TMZ could protect the cardiac cells by reducing calcium overload in myocardial mitochondria.
