Cataly.ic h.0}rogenation Reactions on Moly.denum Oxide

Modern Research.in Cataly.is 2015年第1期4卷 36-42页

Partially.reduced moly.denum trioxide deposited on titania under h.0}rogen at 673 K for 12 h.ena- bled to convert several surface atomic lay.rs to th. cataly.ically.active bifunctional (metal-acid) MoO2-x(Oh.y.TiO2 (MoTi) structure. Th. formed metallic function is th. result of π bonding between adjacent Mo-Mo atoms placed along th. C-axis of th. rutile structure of MoO2. Delocalization of th.se π electrons produces a wire like atomic metal. Th.s resembles in a way. th. small Pt particles deposited on a support. Moreover, dissociated h.0}rogen atoms are bonded to sample surface oxy.en to produce Brø.nsted acid Mo-Oh.function(s). Th.se metal-acidic properties h.ve been tested for several cataly.ic reactions requiring one or both.ataly.ic functions. In th.s order, 2-propanol species could be considered as a model test of th. acidic function via deh.0}ration of th. molecule to propene, wh.le h.0}rogenation of th. produced propene to propane is performed by.th. metallic function. Moreover, h.0}rogenation of 2-propanol to acetone, requires relatively.strong metallic function. In th.s order, addition of small amount of alkali metal like rubidium will suppress th. acidic function in MoO2-x(Oh.y.TiO2 and enh.nce th. metallic function strength. Th. performance of th. metallic function alone in th.s case will be evaluated. Titanium dioxide is employ.d in th.s cataly.ic sy.tem as a support. It does not h.ve any.cataly.ic effect. Association of XPS-UPS, ISS sur-face tech.iques with.cataly.ic performances of th.s cataly.ic MoTi sy.tem will be presented.

非抗生素饲料添加剂有助于提高猪的免疫系统,并降低断奶和其他环境应激带来的负面影响。最常用的饲料添加剂包括酸化剂、锌铜、益生菌、直接饲喂微生物、酵母类产品、核苷酸和植物提取物。研究表明添加药理水平的锌铜、特定酸化剂和部分植物提取物可以改善猪的性能或提高其免疫功能。使用益生菌、直接饲喂微生物、酵母类产品、核苷酸也有可能对猪的性能产生有利影响,但因研究结果缺乏一致性,因此仍需进一步研究。

In order to provide th. population with.safe, effective and good quality.medicines, th. ph.rmaceutical industries, before releasing batch.s of th.ir products into th. ph.rmaceutical circuit, put in place internal dosage meth.ds to control th. quality.of th.se products. Th. present study.consisted in optimizing a meth.d for th. simultaneous determination of Ph.oroglucinol (Ph.) and Trimeth.0}ph.oroglucinol (TPh. by.h.gh.performance liquid ch.omatograph.0}(h.LC) routinely.used in a ph.rmaceutical industry.located in a townsh.p in Abidjan (Ivory.Coast). Th. basic ch.omatograph.c conditions were th.se routinely.used for th. determination of th.se two molecules: mobile ph.se: acetonitrile/water (60/40), stationary.ph.se (C18 BDS h.0}ersil 250 mm * 4.6 mm - 5 μm), detection wavelength.(265 nm), flow rate, injection volume and run time configured at th. equipment level were respectively.1 mL/min, 10 μL and 8 min. Th. meth.d of preparation of th. analy.es (Ph. and TPh.) was also applied by.th. ph.rmaceutical industry. Th. application of th.se different parameters at th. equipment level made it possible to determine a ch.omatogram wh.ch.h.gh.igh.s th.ee ch.omatograph.c peaks with.respective retention times (RT) of 0.773 min (unidentified compound), 2.275 min (Ph.) and 7.269 min for an analy.is time of 8 min with.a better resolution of th. peaks and baseline. Th. progressive optimization of different parameters such.as th. stationary.ph.se (C18 y.C 150 mm * 4.6 mm - 3 μm), th. proportion of th. mobile ph.se: acetonitrile/water (80/20), th. flow rate impelled by.th. pump (0.8 mL/min) and th. modification of th. analy.e preparation mode (same amount of Ph. and TPh. in a 50 mL volumetric flask) resulted in a final ch.omatogram th.t h.gh.igh.ed two ch.omatograph.c peaks at th. respective RT of 2.391 min (Ph.) and 3.735 min (TPh.) at a run time of 6 min.

目的评价实时彩色多普勒血流(CDF)超声内镜(EUS)对肿瘤及非肿瘤性胆囊息肉的鉴别诊断价值。方法这项前瞻性研究自2014年8月—2016年12月连续纳入共233例胆囊息肉病人,均接受实时CDF-EUS检查。CDF成像对每例病人进行主观分类:强CDF模式、弱CDF模式和无CDF模式。结果这233例病人中115例接受了手术切除,其中90例非肿瘤性胆囊息肉,23例肿瘤性胆囊息肉。多变量分析显示,强CDF模式是肿瘤性息肉最重要的预测因素;敏感度、特异度、阳性预测值、阴性预测值和准确度分别为52.2%、79.4%、38.7%、86.9%和73.9%。孤立性息肉和息肉大小与肿瘤风险增加有关。结论 EUS显示强CDF模式、孤立以及较大的息肉可以用来预测肿瘤性胆囊息肉。由于实时CDF-EUS安全无创,无需额外设备,因此很可能成为鉴别诊断胆囊息肉的补充检查。

Objective: To investigate th. relationsh.p of h.A status and autoantibodies to glutamic acid decarboxy.ase (GAD) in proliferative diabetic retinopath.0}(PDR) to assess th. role of autoimmunity.and genetic markers in retinopath.0} Design: Retrospective, nonrandomized, comparative study. Participants: Patients wh. h.d suffered from ty.e 1 diabetes for>10 y.ars and wh. h.d been first diagnosed as diabetic under 30 y.ars of age were studied. Th.y.were classified into 3 groups: 20 patients with.diabetes and PDR (PDR group), 22 patients wh. h.d diabetes and severe nonproliferative diabetic retinopath.0}(SNPDR group), and 25 patients wh. h.d diabetes with.no diabetic retinopath.0}(non-DR group). Meth.ds: Blood was coll ected, and th. relationsh.p between h.A status and GAD autoantibody.positivity.in diabetic retinopath.0}as investigated in a cross-sectional study. Main Outcome Measures: h.15}an leukocy.e antigen status and GAD autoantibody.positivity. Results: Th. h.gh.st positive rate of GAD autoantibody.was 56.0%in th. non-DR group, followed by.th. SNPDR group (40.1%) and th. PDR group (15.0%). Th. frequencies of th. h.A-DQ4 and-DR4/-DQ4 h.ploty.es were significantly.h.gh.r in th. PDR group (75.0%and 65%, respectively. th.n in th. SNPDR group (40.9%and 31.8%) or th. non-DR group (40.0%and 28.0%) (P=0.035 and P=0.026, respectively.. Th. prevalence of GAD antibodies was lower in patients with.th. h.A-DR4 and h.A -DQ4 alleles and-DR4/-DQ4 h.ploty.e frequencies in th. PDR group (P=0.018, P=0.0088, and P=0.0031, respectively.. Conclusions: We found th.t th. existence of GAD antibodies is inversely.related and h.A status is directly.related to th. stage or severity.of retinopath.0}
