In this work, we study the influence of the average crystallite size and dopant oxide on the reducibility of CeO2-based nanomaterials. Samples were prepared from commercial Gd2O3-, Sm2O3- and Y2O3-doped CeO2 powders by calcination at different temperatures ranging between 400°C and 900°C and characterized by X-ray powder diffraction, transmission electron microscopy and BET specific surface area. The reducibility of the samples was analyzed by temperature-programmed reduction and in situ dispersive X-ray absorption spectroscopy techniques. Our results clearly demonstrate that samples treated at lower temperatures, of smallest average crystallite size and highest specific surface areas, exhibit the best performance, while Gd2O3-doped ceria materials display higher reducibility than Sm2O3- and Y2O3-doped CeO2.

AIM: To investigate feasibility and accuracy of near-infrared fluorescence imaging using indocyanine green: nanocolloid for sentinel lymph node (Sln) detection in gastric ***: A prospective, single-institution, phase I feasibility trial was conducted. Patients suffering from gastric cancer and planned for gastrectomy were included. During surgery, a subserosal injection of 1.6 ml ICG:nanocoll was administered around the tumor. nIR fluorescence imaging of the abdominal cavity was performed using the Mini-FlARE™ nIR fluorescence imaging system. lymphatic pathways and Slns were visualized. Of every detected Sln, the corresponding lymph node station, signal-to-background ratio and histopathological diagnosis was determined. Patients underwent standard-of-care gastrectomy. Detected Slns outside the standard dissection planes were also resected and ***: Twenty-six patients were enrolled. Four patients were excluded because distant metastases were found during surgery or due to technical failure of the injection. In 21 of the remaining 22 patients, at least 1 Sln was detected by nIR Fluorescence imaging (mean 3.1 Slns; range 1-6). In 8 of the 21 patients, tumor-positive lns were found. Overall accuracy of the technique was 90% (70%-99%; 95%CI), which decreased by higher pT-stage (100%, 100%, 100%, 90%, 0% for respectively Tx, T1, T2, T3, T4 tumors). All nIR-negative Slns were completely effaced by tumor. Mean fluorescence signal-to-background ratio of Slns was 4.4 (range 1.4-19.8). In 8 of the 21 patients, Slns outside the standard resection plane were identified, that contained malignant cells in 2 ***: This study shows successful use of ICG:nanocoll as lymphatic tracer for Sln detection in gastric cancer. Moreover, tumor-containing lns outside the standard dissection planes were identified.

【目的】为明确氮素穗肥对杂交稻籽粒灌浆和淀粉合成关键酶活性的影响。【方法】选用两个直链淀粉含量差异较大的杂交稻品种锦优1319(高直链淀粉)和蓉优702(低直链淀粉),在不同的氮素穗肥处理下(设0、60、90和120 kg/hm^(2)4个纯氮水平,分别用CK、n1、n2、n3表示)研究氮素穗肥水平对籽粒灌浆和淀粉合成关键酶活性的影响。【结果】不同穗肥处理下杂交稻籽粒灌浆特性差异显著,且不同类型品种表现各异,其中氮素穗肥的施用显著降低了稻米的直链淀粉含量。锦优1319的Gmax和Gmean随氮素穗肥水平的变化均表现为n2>CK>n1>n3,而蓉优702则表现为n3>n2>CK>n1;施用氮素穗肥显著增加了花后5~25 d籽粒腺苷二磷酸焦磷酸化酶(ADPG)和淀粉分支酶(DBE)的活性,降低了花后5~15 d籽粒GBSS活性,降低了花后5~25 d籽粒淀粉合成酶(SSS)和SBE活性。【结论】高直链淀粉品种锦优1319籽粒灌浆的最佳氮素穗肥施用量低于低直链淀粉品种蓉优702:其中锦优1319的最佳氮素穗肥施用量为90 kg/hm^(2),蓉优702为120 kg/hm^(2)。施用氮素穗肥显著降低了GBSS、SSS的活性,加之SBE活性下降,DBE活性提高,最终降低稻米直链淀粉含量。本研究条件下,籽粒ADPG活性未对稻米直链淀粉含量产生显著影响。

A novel dinuclear complex [Co2(atr)3(mal)2(h2O)2]·4h2O(1) (atr = 4-amino-1,2,4-triazole and mal = malonic acid) containing mixed n and O-donor atoms has been prepared and structurally characterized. The structure is made up of the symmetrically 1, 2, 4-triazole bridged [Co2(atr)3(mal)2(h2O)2] moiety and four lattice water molecules. The single crystal X-ray analysis reveals that the complex has a distorted octahedral structure. Magnetic susceptibility measurements reveals that antiferromagnetic interactions exists between the high spin Co(II) ions within the dinuclear unit.

Background: Abstinence and anger control are promoted as ways to improve quality of life. Trait anger has been seen as one casual factor for alcohol related aggression and poor quality of life. The present study assesses anger control, quality of life and its relation with trait anger among alcohol dependents, abstainers & social drinkers. Material & Method: 150 subjects (50 subjects in each group) in the age range of 20 - 45 years were taken for the study. Semi-structured interview schedule, State-Trait Anger Expression Inventory-2, WhOQOl-BREF were administered in individual setting. Results: Dependent alcohol users and abstainers reported the significant impact of alcohol use on family & occupational functioning. Quality of life has correlation with anger control (in/out), trait anger, temperament & reaction in the control & abstainers group, whereas quality of life has negative correlation with trait anger expression among the alcohol group. Conclusions: Alcohol use has been associated with the trait anger expression and poor quality of life. It has implications for promoting alcohol abstinence, in improving quality of life and in anger control.
