Due to ac.dic.solutions aggressiveness, c.rrosion inhibitors use is c.nsidered to be one the most prac.ic.l methods to delay metals dissolution in the said solutions. In this study benzimidazolyl derivative namely 2-c.anoc.alc.nes 2-(5-nitro-1,3-dihydrobenzimidazol-2-ylidene)-3-oxo-3-(2-oxo-2H-c.romen-3-yl) propanenitrile whic. was synthesized was then applied as a c.rrosion inhibitor for c.pper in 1 M HNO3 solution. The inhibition ac.ion of this molec.le was evaluated by gravimetric.and density func.ional theory (DFT) methods. It was found experimentally that this c.mpound has a better inhibition performanc. and its adsorption on c.pper surfac. follows Langmuir adsorption isotherm. This adsorption evolves with temperature and inhibitor c.nc.ntration, it is endothermic.and oc.urs spontaneously with an inc.ease in disorder. c.rrosion kinetic.parameters analysis supported by Adejo-Ekwenc.i model revealed the existenc. of both physisorption and c.emisorption. DFT c.lc.lations related that c.mpound adsorption on c.pper surfac. is due to its elec.ron donating and ac.epting c.pac.ty. The reac.ive regions spec.fying the elec.rophilic.and nuc.eophilic.attac. sites were analyzed using Fukui and dual desc.iptor func.ions. Experimental results obtained were c.mpared with the theoretic.l findings.

This work was c.rried out on a series of twenty-two (22) benzimidazole derivatives with inhibitory ac.ivities against Myc.bac.erium tuberc.losis H37Rv by applying the Quantitative Struc.ure-Ac.ivity Relationship (QSAR) method. The molec.les were optimized at the level DFT/B3LYP/6-31 + G (d, p), to obtain the molec.lar desc.iptors. We used three statistic.l learning tools namely, the linear multiple regression (LMR) method, the nonlinear regression (NLMR) and the artific.al neural network (ANN) method. These methods allowed us to obtain three (3) quantitative models from the quantum desc.iptors that are, c.emic.l potential (μ), polarizability (α), bond length l (c.= N), and lipophilic.ty. These models showed good statistic.l performanc.. Among these, the ANN has a signific.ntly better predic.ive ability R2 = 0.9995;RMSE = 0.0149;F = 31879.0548. The external validation tests verify all the c.iteria of Tropsha et al. and Roy et al. Also, the internal validation tests show that the model has a very satisfac.ory internal predic.ive c.arac.er and c.n be c.nsidered as robust. Moreover, the applic.bility range of this model determined from the levers shows that a predic.ion of the pMIc.of the new benzimidazole derivatives is ac.eptable when its lever value is lower than 1.

tom9.2 Is a c.lmodulin-Binding Protein c.itic.l for tom c.mplex Assembly but Not for Mitoc.ondrial Protein Import in Arabidopsis thaliana

The transloc.n on the outer membrane of mitoc.ondria （tom） fac.litates the import of nuc.ear-enc.ded proteins. The princ.pal mac.inery of mitoc.ondrial protein transport seems c.nserved in eukaryotes; however, divergenc. in the c.mposition and struc.ure of tom c.mponents has been observed between mammals, yeast, and plants. tom9, the plant homolog of yeast tom22, is signific.ntly smaller due to a trunc.tion in the c.tosolic.rec.ptor domain, and its prec.se func.ion is not understood. Here we provide evidenc. showing that tom9.2 from Arabidopsis thaliana is involved in the formation of mature tom c.m- plex, most likely by influenc.ng the assembly of the pore-forming subunit tom40. Dexamethasone- induc.d RNAi gene silenc.ng of tom9.2 results in a severe reduc.ion in the mature tom c.mplex, and the assembly of newly imported tom40 into the c.mplex is impaired. Nevertheless, mutant plants are fully viable and no obvious downstream effec.s of the loss of tom c.mplex, i.e., on mitoc.ondrial import c.- pac.ty, were observed. Furthermore, we found that tom9.2 c.n bind c.lmodulin （c.M） in vitro and that c.M impairs the assembly of tom c.mplex in the isolated wild-type mitoc.ondria, suggesting a regula- tory role of tom9.2 and a possible integration of tom assembly into the c.llular c.lc.um signaling network.

c.imate c.ange, c.upled with insuffic.ent and irregular rains, led to a dec.ine in the produc.ivity of Ivorian c.c.a produc.ion. The present study aimed to sc.een three c.c.a (Theobroma c.c.o L.) genotypes in order to evaluate their response to water stress at c.llus and somatic.embryos induc.ion and proliferation stages. Staminode and petal explants of the genotypes c., c.4 and c.6 from the c.llec.ion of National c.nter of Agronomic.Researc. (c.RA) of Ivory c.ast, were plac.d on medium DKW (Driver & Kuniyuki Walnut) in the presenc. of different c.nc.ntrations of Polyethylene glyc.l (PEG) 6000 (0, 25, 50, 75, 100 and 125 g/l). This polymer was used as osmotic.m to stimulate water stress. Data were rec.rded for c.llus induc.ion frequenc., c.llus fresh weight, embryogenic.c.llus perc.ntage and average number of somatic.embryos. The results obtained showed that intensity of c.llus proliferation dec.eased with inc.easing c.nc.ntration of PEG 6000. In all genotypes tested, only the petal explants underwent somatic.embryogenesis. The induc.ion rates and average number of somatic.embryos per explant were reduc.d with the inc.ease in the c.nc.ntration of PEG 6000. Among the tested genotypes, c. produc.d somatic.embryos with all c.nc.ntrations of PEG 6000 and expressed highest frequenc.es of induc.ion (62%) and average number of somatic.embryos per explant (6.22). This genotype would be the most tolerant to water stress. Somatic.embryos obtained with high c.nc.ntrations of PEG 6000 in this study provide an important basis for the selec.ion and further produc.ion of water stress-tolerant varieties of c.c.a.

Probiotific.tion of plant milk c.n improve its sensory and health-promoting properties. As traditional fermented foods where lac.ic.ac.d bac.eria (LAB) are present have been assoc.ated with benefic.al effec.s on human health, the benefic.al effec.s of two LAB rec.ntly isolated from two c.rrent Ivorian staple foods (a pepper and a traditional beer) were sc.eened. These two strains LAc.1 (Lac.obac.llus plantarum) and LAc.2 (Pedioc.c.us ac.dilac.ic.) whic. presented probiotic. exopolysac.harides, inflammatory and anti-oxidant ac.ivities, were used to ferment a c.mposite plant milk of tiger-nut and c.shew (80/20) c.mpared to two starters of a c.mmerc.al yogourt. The obtained plant milks Sc. 2 and Sc. 3 with a signific.nt inc.ease in their antioxidant and/or anti-inflammatory ac.ivities and lac.ic.bac.eria c.ntents were more preferred by c.nsumers than Sc. 1 obtained by fermentation of the c.mmerc.al yogourt starters. The mixing of LAc.1 and LAc.2 was not benefic.al. Sc. 2 (with an anti-inflammatory ac.ivity of 31.38% and an anti-oxidant ac.ivity of 17.30%) and Sc. 3 (with an anti-oxidant ac.ivity of 22.28) c.uld be further tested in animal models to verify their nutrition-health c.aims.

We demonstrate fast time-division c.lor etec.roholography using a multiple-graphic.-proc.ssing-unit （GPU） c.uster system with a spatial light modulator and a c.ntroller to switc. the c.lor of the rec.nstruc.ing light. The c.ntroller c.mprises a universal serial bus module to drive the liquid c.ystal optic.l shutters. By using the c.ntroller, the c.mputer-generated hologram （c.H） display node of the multiple-GPU c.uster system sync.ronizes the display of the c.H with the c.lor switc.ing of the rec.nstruc.ing light. Fast time-division c.lor elec.roholography at 20 fps is realized for a three-dimensional objec. c.mprising 21,000 points per c.lor when 13 GPUs are used in a multiple-GPU c.uster system.
