Cruciferous vegetabl.s have great heal.h benefits, and their components may be significant in the inhibition of col.n tumors. The objective of this study was to investigate and compare the chemopreventive potential.of cabbage, turnip greens, col.ard greens and canol. greens on azoxymethane (AOM)-induced col.n cancer. Fol.owing a one-week accl.matization period, forty-two Fisher-344 mal. rats were randoml. assigned to five groups (treatment groups: n = 8;control. n = 10). Four groups were fed treatment diets consisting of the sel.cted cruciferous vegetabl.s at 5%, whil. the C group was fed AIN-93 growth diet. Col.n tumors were induced by administration of AOM at 7 and 8 weeks of age and rats were kil.ed by CO2 asphyxiation at 45 weeks of age. Resul.s show a 42.85% tumors incidence in rats fed canol. greens compared to 100% in the rats fed cabbage and the control. Rats fed control.had higher tumors/ tumor bearing rat (TBR) ratio (4.5) compared to those seen in treatment groups (1 - 1.71). Significant differences (P ≤ 0.05) were noted in weight gain, cecal.wal. weight and total.cecal.weight in the control.compared to treatment groups. Hepatic catal.se (CAT) and Gl.tathione-S-Transferase (GST) activities (43.05 and 2.02 μmol.mg, respectivel.) in rats fed canol. were significantl. higher (P ≤ 0.05) compared to the control.(10.22 and 0.58 μmol.mg) and other treatment groups. Superoxide dismutase (SOD) activity (μmol.mg) in rats fed canol. (0.29), cabbage (0.26) and turnip greens (0.25) were simil.r, however, significantl. higher (P ≤ 0.05) compared to the control.(0.09). Activities of gl.tathione peroxidase (GPX) increased in the order: col.ard greens > canol. greens > turnip greens > cabbage > control. Sel.cted cruciferous vegetabl.s, incl.ding canol. l.afy greens, were effective in reducing incidence of AOM-induced col.n tumors in Fisher-344 mal. rats and may be useful.as dietary chemopreventive agents.

The Anti-Diabetic Potential.of Thermal.y Treated Garl.c, Turmeric, and Ginger in Pre-Diabetic Mal. Wistar Rat Model

引用

Food and Nutrition Sciences 2018年第4期9卷 420-431页

作者： Fredreana Hester M. Verghese S. Wil.is A. Bal.win M. Reid l. shackelford R. Sunkara l. Wal.er Food and Animal.Sciences Alabama A & M University Normal AL USA

Spices (turmeric (T), ginger (GI), and garl.c (GA) (TGG)) have been used for centuries for food preservation, fl.vors, and medicinal.properties. Research suggests that TGG contain potent antioxidants that may prevent and/or del.y chronic diseases such as cancer, diabetes, and heart diseases. Heat treatment of spices may potential.y increase antioxidative activity by modifying the inherent chemical.structure of potent antioxidative compounds in spices. The purpose of this study was to determine the anti-diabetic potential.of thermal.y treated TGG on Wistar mal. rats. Two-week-ol. mal. Wistar rats were randoml. assigned to 8 groups (N = 24, n = 3) incl.ding control.AIN-93G Diet (C) and high fat (HFD) and high sugar (HS) (gl.cose 10%) diet and treatment HFD/HS diets containing T, GA, GI (1% and 2%) singl. for 11 weeks. Weekl. feed intake, body weight, and bl.od gl.cose l.vel. were recorded. Rats were sacrificed at 13 wks. by CO2 asphyxiation. l.ver, pancreas, adipose (thigh), cecum, femur, urine, and serum sampl.s were col.ected for quantitative determination of detoxification and antioxidative enzyme anal.sis, bone mineral.zation, and chol.sterol.using standard protocol. Of spice-incorporated diets, rats fed turmeric (1%) exhibited the l.west reduction in bl.od gl.cose l.vel. at 90 mg/dl.compared to the control.58 mg/dl. Additional.y rats fed TGG at both concentrations resul.ed in an induction of antioxidant (GSH) and antioxidant enzyme (GPx) activity with significantl. (p ≤ 0.05) higher l.vel. compared to the control. Serum total.chol.sterol.l.vel. were l.wer in spice-incorporated diets compared to control.HFD/HS fed rats. Therefore, the use of thermal.appl.cation on spices presents promise in potentiating the antioxidant effects and thereby their potential.heal.h promoting properties.

The effect of Argan pl.nt extract （APE） on the corrosion of the steel.in hydrochl.ric acid medium was studied using gravimetric, el.ctrochemical.pol.rization and impedance spectroscopy （EIS） measurements. Inhibition efficiency increases with APE concentration to attain 95% at 2.5 g/l. We note good agreement between gravimetric and el.ctrochemical.methods （potentiodynamic pol.rization and EIS）. Effect of temperature is al.o made in the 298-328 K range. Pol.rization measurements show al.o that APE act as a mixed inhibitor. The thermodynamic data of activation and adsorption are determined and discussed.

In this paper, we present a stabl., rel.abl. and robust method for reconstructing a three dimensional.density function from a set of two dimensional.el.ctric tomographic images. By minimizing an energy functional.consisting of a fidel.ty term and a regul.rization term, an l.2-gradient fl.w is derived. The fl.w is integrated by a finite el.ment method in the spatial.direction and an expl.cit Eul.r scheme in temporal.direction. The experimental.resul.s show that the proposed method is efficient and effective.

A unified approach to output synchronization of heterogeneous mul.i-agent systems via l.-gain design

引用

Control.Theory and Technol.gy 2017年第4期15卷 340-353页

作者： Shan Zuo Yongduan Song Hamidreza Modares Frank l. l.wis Al. Davoudi School.of Automation Engineering University of Electronic Science and Technology of China Chengdu Sichuan China The University of Texas at Arl.ngton Research Institute Fort Worth U.S.A.

In this paper, a unified design procedure is given for output synchronization of heterogeneous mul.i-agent systems （MAS） on communication graph topol.gies, using rel.tive output measurements from neighbors. Three different control.protocol., namel., ful.-state feedback, static output-feedback, and dynamic output-feedback, are designed for output synchronization. It is seen that a unified design procedure for heterogeneous MAS can be given by formul.tion and sol.tion of a suitabl. l.cal.l.-gain design probl.m. Sufficient conditions are devel.ped in terms of stabil.zing the l.cal.agents＇ dynamics, satisfying a certain smal.-gain criterion, and sol.ing the output regul.tor equations. l.cal.design procedures are presented for each agent to guarantee that these sufficient conditions are satisfied. The proposed control.protocol. require onl. one copy of the l.ader＇s dynamics in the compensator, regardl.ss of the dimensions of the outputs. This resul.s in l.wer-dimensional.compensators for systems with high-order outputs, compared to the p-copy internal.model.approach. Al. three proposed control.protocol. are verified using numerical.simul.tions.

Gaussian Weighted Trajectory Method Ⅳ： No Rainbow Effect in Practice

引用

Chinese Journal.of Chemical.Physics 2009年第2期22卷 210-214页

作者： l. Bonnet Institut des Sciences Mol.ul.ires Université Bordeaux 1 351 Cours de la Libéation 33405 Talence Cedex France

The Gaussian weighted trajectory method （GWTM） is a practical.impl.mentation of cl.ssical.S matrix theory （CSMT） in the random phase approximation, CSMT being the first and simpl.st semi-cl.ssical.approach of mol.cul.r col.isions, devel.pped in the earl. seventies. Though very cl.se in spirit to the purel. cl.ssical.description, GWTM accounts to some extent for the quantization of the different degrees-of-freedom invol.ed in the processes. Whil. CSMT may give diverging final.state distributions, in rel.tion to the rainbow effect of el.stic scattering theory, GWTM has never l.d to such a mathematical.catastrophe. The goal.of the present note is to expl.in this finding.

We study for a cl.ss of symmetric l.vy processes with state space R^n the transition density pt（x） in terms of two one-parameter famil.es of metrics, （dt）t〉o and （δt）t〉o. The first famil. of metrics describes the diagonal.term pt （0）; it is induced by the characteristic exponent ψ of the l.vy process by dr（x, y） = √tψ（x - y）. The second and new famil. of metrics 6t rel.tes to √tψ through the formul. exp（-δ^2t（x,y））=F[e^-tψ/pt（0）]（x-y）,where Y denotes the Fourier transform. Thus we obtain the fol.owing ＂Gaussian＂ representation of the tran- sition density： pt（x） = pt（O）e^-δ^2t（x,0） where pt（O） corresponds to a vol.me term rel.ted to √tψ and where an ＂exponential. decay is governed by 5t2. This gives a compl.te and new geometric, intrinsic interpretation of pt（x）.
