Energy transfer mechanism of the luminescence in the complex was discussed.

Syntheses of Coordination Compounds of 2-Amino-3-Methylbutanoic Acid Their Mixed Ligand Complexes and Antibacterial Activities

Coordination compounds of 2-amino-3-methylbutanoic acid were synthesized with chromium(III) and oxovanadium(IV) ions. M:L;1:2. Adducts of these complexes using 1,10-phenantroline and ethylenediamine were further synthesized, M:L, (1:2). These compounds were characterized using electronic, infra-red spectrophotometry, magnetic susceptibility measurement and percentage metal analyses. The zones of inhibition and minimum inhibitory concentrations of the compounds against eight microbes were studied. The results obtained indicated an octahedral geometry for the Cr(III) complexes, indicative of additional coordination of two water molecules. On the other hand a square pyramid geometry was obtained for the binary oxovanadium complex and its 1,10-phenantroline adduct. However, for the oxovanadium ethylenediamine adduct a distorted octahedral geometry was proposed. The result for the antibacterial studies indicated that both mixed ligand complexes of 1,10-phenantroline exhibited good antibacterial activity, and in some cases better activity than the standard, streptomycin.

Both the primary and secondary ligands coordinated in a bidentate fashion. The synthesized compounds exhibited moderate cytotoxicity, although none was as active as the standard. The cobalt(III) mixed ligand complex elicited the highest activity. The synthesized compounds all exhibited good to moderate antioxidant activity.

Influence of pyrolytic carbon coatings on complex permittivity and microwave absorbing properties of Al_2O_3 fiber woven fabrics

The pyrolytic carbon （PyC） coatings were fabricated on A1203 fiber fabrics by the method of chemical vapor deposition （CVD）. The microstructures of A1203 fibers with and without PyC coatings were characterized by SEM and Raman spectroscopy. The influence of deposition time of PyC on the DC conductivity （ad） of A1203 filaments and complex permittivity of fabrics at X band （8.2-12.4 GHz） were investigated. The values of Crd and complex permittivity increase with increasing deposition time of PyC. The electron relaxation polarization and conductance loss were supposed to be contributed to the increase of ε＇ and ε＂, respectively. In addition, the reflection loss （RL） of fabrics was calculated. The results show that the microwave absorbing properties of Al2O3 fiber fabrics can be improved by PyC coatings. The best RL results are for 60 min-deposition sample, of which the minimum value is about -40.4 dB at about 9.5 GHz and the absorbing frequency band （AFB） is about 4 GHz.

Non-SMC condensin Ⅰ complex subunit D2 and non-SMC condensin Ⅱ complex subunit D3 induces inflammation via the IKK/NF-κB pathway in ulcerative colitis

BACKGROUND Ulcerative colitis(UC)is a chronic,nonspecific intestinal inflammatory disease with undefined pathogenesis.Non-SMC condensin I complex subunit D2(NCAPD2)and non-SMC condensin II complex subunit D3(NCAPD3)play pivotal roles in chromosome assembly and segregation during both mitosis and meiosis.To date,there has been no relevant report about the functional role of NCAPD2 and NCAPD3 in UC.AIM To determine the level of NCAPD2/3 in intestinal mucosa and explore the mechanisms of NCAPD2/3 in UC.METHODS Levels of NCAPD2/3 in intestinal tissue were detected in 30 UC patients and 30 healthy individuals with in situ hybridization(ISH).In vitro,NCM60 cells were divided into the NC group,model group,si-NCAPD2 group,si-NCAPD3 group and si-NCAPD2+si-NCAPD3 group.Inflammatory cytokines were measured by ELISA,IKK and NF-κB were evaluated by western blot,and IKK nucleation and NF-κB volume were analyzed by immunofluorescence assay.RESULTS Compared with expression in healthy individuals,NCAPD2 and NCAPD3 expression in intestinal tissue was significantly upregulated(P<0.001)in UC patients.Compared with levels in the model group,IL-1β,IL-6 and TNF-αin the si-NCAPD2,si-NCAPD3 and si-NCAPD2+si-NCAPD3 groups were significantly downregulated(P<0.01).IKK and NF-κB protein expression in the si-NCAPD2,si-NCAPD3 and si-NCAPD2+si-NCAPD3 groups was significantly decreased(P<0.01).Moreover,IKK nucleation and NF-κB volume were suppressed upon si-NCAPD2,si-NCAPD3 and si-NCAPD2+si-NCAPD3 transfection.CONCLUSION NCAPD2/3 is highly expressed in the intestinal mucosa of patients with active UC.Overexpression of NCAPD2/3 promotes the release of pro-inflammatory cytokines by modulating the IKK/NF-κB signaling pathway.

Kinetics of Reactive Extraction of Nd from Nd2O3 with TBP-HNO3 Complex in Supercritical Carbon Dioxide

The process based on supercritical fluid extraction for reprocessing of the spent nuclear fuel has some remarkable advantages over the plutonium-uranium extraction(PUREX) process.Especially,it can minimize the generation of secondary waste.Dynamic reactive extraction of neodymium oxide(Nd2O3) in supercritical carbon dioxide(SC-CO2) containing tri-n-butyl phosphate-nitric acid(TBP-HNO3) complex was investigated.Temperature showed a positive effect on the extraction efficiency,while pressure showed a negative effect when the unsaturated TBP-HNO3 complex was employed for the dynamic reactive extraction of Nd2O3 in SC-CO2.Both temperature and pressure effects indicated that the kinetic process of the reactive extraction was controlled by the chemical reaction.A kinetic model was proposed to describe the extraction process.
