An efficient cell suspension culture system has been initiated using callus obtained from mature seeds of the.c.inese Japonica variety eryi 105 as a source. Over the last 12 months, using the ″Nottingham Method″, protoplasts have been produced from these.c.ll suspensions, and via the PeG method of transformation. 45 regenerated plants were obtained from DNA-treated protoplasts selected by 80μg/ml G418. The research of molecular analysis on those plantlets is being carried on by Plant Genetic Manipulation Group, Department of Life Scie.c., University of Nottingham, U.K.

The.c.mputerized ge.c.emical modeling, a useful tool to understand the diagenetic processes influe.c.ng the quality of hydrocarbon reservoirs, is performed by using different modules of computer codes based on the thermodynamic and chemical kinetic principles and their associated parameters. As observed in the reservoir lithofacies deposited from the marine sediment-gravity flows, a case study of diagenesis is presented here from the espírito Santo Basin in southeastern Brazil. The study uses the Ge.c.emist＇s Workbe.c.（GWB～（TM））, PHRee.c.（TM） and TOUGHRe.c.～（TM） computation packages. The.c.mparison of performances of these packages demonstrates the.c.nverge.c. of results from the software-based ge.c.emical modeling with the petrographic observation of dissolution, albitization, kaolinization, and the precipitation of calcite and dolomite. Moreover, with limited data points, e.g., the sedimentary petrographic data acquired from limited number of boreholes, the.c.mputer simulation establishes itself to be a powerful quantitative method estimating the degree and type of diagenetic alteration of turbidite reservoir bodies in contact with a source of saline-water influx associated with salt ***, using the limited petrographic data points, the ge.c.emical computer-simulation method can even be utilized and extrapolated for areas where similar geological context is interpreted but no borehole data are available. He.c., porosity of turbidite reservoir lithofacies can be predicted in relation to the spatial distribution of dissolution, kaolinization, and albitization of feldspars and authigenic carbonate precipitation.

The N-terminal eF-hand calcium-binding proteins 1–3(NecAB1–3) constitute a family of predominantly neuronal proteins characterized by the prese.c. of at least one eF-hand calcium-binding domain and a functionally less well characterized c-terminal antibiotic biosynthesis monooxygenase domain. All three family members were initially discovered due to their interactions with other proteins. NecAB1 associates with synaptotagmin-1, a critical neuronal protein involved in membrane trafficking and synaptic vesicle exocytosis. NecAB2 interacts with predominantly striatal G-protein-coupled receptors, while NecAB3 partners with amyloid-β A4 precursor protein-binding family A members 2 and 3, key regulators of amyloid-β production. This demonstrates the.c.pacity of the family for interactions with various classes of proteins. NecAB proteins exhibit distinct subcellular localizations: NecAB1 is found in the nucleus and cytosol, NecAB2 resides in endosomes and the plasma membrane, and NecAB3 is present in the endoplasmic reticulum and Golgi apparatus. The antibiotic biosynthesis monooxygenase domain, an evolutionarily ancient component, is akin to atypical heme oxygenases in prokaryotes but is not wellcharacterized in vertebrates. Prokaryotic antibiotic biosynthesis monooxygenase domains typically form dimers, suggesting that calcium-mediated conformational changes in NecAB proteins may induce antibiotic biosynthesis monooxygenase domain dimerization, potentially activating some enzymatic properties. However, the substrate for this enzymatic activity remains uncertain. Alternatively, calcium-mediated conformational changes might influe.c. protein interactions or the subcellular localization of NecAB proteins by controlling the availability of protein–protein interaction domains situated between the eF hands and the antibiotic biosynthesis monooxygenase domain. This review summarizes what is known about genomic organization, tissue expression, intracellular localization, interac

Duloxetine(DUL), an antidepressant drug, has been detected in surface water and wastewater effluents, however, there is little information on the formation of its transformation products(TPs). In this work, hydrolysis, photodegradation(UV irradiation) and chlorination experiments were performed on spiked distillated water, under controlled experimental conditions to simulate abiotic processes that can occur in the environment and wastewater treatment plants(WWTPs). eleven TPs, nine from re.c.ion with UV light and two from chlorine.c.ntact, were formed and detected by ultra-high performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry, and nine of them had their chemical structures elucidated upon analyses of their fragmentation patterns in MS/MS spectra. The formation and degradation of the TPs were observed. The parent compound was completely degraded after30 min in photodegradation and after 24 hr in chlorination. Almost all TPs were.c.mpletely degraded in the experiments. The ecotoxicity and mutagenicity of the TPs were predicted based on several in silico models and it was found that a few of these products presented more ecotoxicity than DUL itself and six TPs showed positive mutagenicity. Finally, wastewater samples were analyzed and DUL and one TP, possibly formed by chlorination process, were detected in the effluent, which showed that WWTP not only did not remove DUL, but also formed a TP.
