The objective of this study was to evaluate supplemental organic chromium（Cr） to finishing lambs on growth performance, carcass characteristics, and meat quality. Eighteen suffolk lambs（age（4.5±0.2） mon;（25.8±3.6） kg body weight（BW）） were randomly assigned to three levels of supplemental organic Cr（0.0, 0.2 and 0.4 mg kg^–1 dry matter（DM）） in a complete random design. Growth performance was evaluated for 70 d, and then lambs were slaughtered to study carcass characteristics and chemical composition of meat. Orthogonal contrasts were performed（contrast one-average level 0.2 ppm Cr vs. average level 0.4 ppm Cr; contrast two-level 0 vs. average levels（0.2＋0.4） ppm Cr）. Orthogonal polynomials were used to estimate the linear and quadratic effects of Cr concentrations. Growth and carcass performance were not affected by supplemental organic Cr. Muscle conformation and leg perimeter linearly increased（P〈0.05） as organic Cr level increased in the diet. Kidney fat decreased linearly（P〈0.05） as supplemental Cr increased. In Longissimus dorsi（LD）, the ash content decreased linearly, and shear force（kg cm^–2） increased（P〈0.05） as organic Cr level increased in the diet. It is concluded that organic Cr did not affect growth performance, but it improved positively the muscle conformation, reduced kidney fat, whereas in LD there was an increment in shear force in finishing carcass lambs.

The productive performance of giant freshwater prawn （Macrobrachium rosenbergii de Man） fed diet containing silkworm pupae （Bombyx mori） replacing for fish meal was conducted by focusing on digestibility, growth performance and feed utilization. Five diets of an isonitrogenous of 35 ：e 1% crude protein and isocaloric of digestible energy of 3,200 ±100 kcal/kg were formulated by using silkworm pupae, 0%, 8.6%, 17.2%, 25.8% and 34.7% by weight, replaced for fish meal. Giant freshwater prawn of 19 ± 2.0 g were stocked at 5 ind./m3 in concrete tank of 2.25 ton for three months. The protein digestibility by pepsin enzyme was evaluated in fish meal, silkworm pupae, soybean meal and shrimp meal. The digestibility was significantly difference （P 〈 0.05）. The protein digestibility of fishmeal and soybean meal was higher than silkworm pupae and shrimp meal. The productive performance of prawn in terms of growth rate and feed utilization were not significantly different （P 〉 0.05）. Therefore, silkworm pupae can be replaced for fishmeal in giant freshwater prawn （Macrobrachium rosenbergii de Man） without any adverse effects on productive performance.

Aims: To assess the correlation between optical coherence tomography (OCT) and leakage on fundus fluorescein angiography (FFA) following photodynamic therapy (PDT) with verteporfin for choroidal neovascularisation (CNV). Methods: Retrospective comparative observational case series of patients who were treated with PDT for CNV from one centre. All patients had 3 monthly FFA and OCT following initial PDT to assess if further treatment was required. A pair of FFA and OCT images from the same visit at a random follow up date were taken from each patient’ s series and assessed separately by different observers. The presence of pigment epithelial detachment,subretinal fluid,vitreomacular traction,intraretinal fluid,absence of foveal depression,and the retinal thickness on OCT were correlated with presence of leaks on FFA. Results: A total of 121 eyes of 121 patients were included. The presence of subretinal fluid,gross cystoid macular oedema,sponge-like retinal thickening and retinal thickness of more than 350 μ mon OCT correlated well with leak on FFA (p value s were 3.0,5.7,2.7,and 3.6,respectively. The presence of a solitary foveal cyst did not correlate well with leaks on FFA. Conclusions: The presence of subretinal fluid,intraretinal fluid in the form of gross cystoid macular oedema,or sponge-like retinal thickening,or a retinal thickness more than 350 μ m correlates with leaks on FFA and so suggests the need for repeat PDT.

本文提出了一套确定直接成分(简称 IC)的系统的理论和方法。全文共分六节:1)扩展,2)进一步的方法,3)结构,4)词,5)多直接成分和非连续成分,6)英语的音渡、重音和音高。在第一节里,作者指出扩展是 IC 分析的基本原则,并对这条原则做了具体的说明(作者所说的扩展跟我们一般所说的扩展有所不同)。作者举 The king of England opened Parliament“英国国王召开议会”为例,证明 The||king|||of||||England|open|||ed||Parliament 的分析是最好的一种分析,因为它是 John worked“约翰工作”的扩展。作者在达一节中对“语素类”、“序列类”、“结构体”、“焦点”、“焦点类”、“外部语法”、“内部语法”等术语下了定义。作者在第二节里指出对某一个句子作 IC 的分析并不是孤立的,而应当考虑到这种语言的整个 IC 系统。因此,在分析时应当拿一种 IC 的分析跟共他可能有的 IC 分析此较,以此来检验我们的分析是否正确。在这一步工作里,作者提出了“关联类”和“聚合体”的概念。在第三节里,作者指出 IC 分析应当反映秸构。分析秸构时应当把意义考虑在内。例如,Old mon and women就有1)“年老的男人和年老的女人”,以及2)“女人和年老的男人”两种意义,因此这个短语的 IC 分析也相应地有1)Old|men and women,和2)Old men|and|women 两种。作者在这一节里还把同音的结构区分为全部同音和部分同音。作者在第四节里提出词在 IC 分析中是一个有关的单位。有很多话语的 IC 分析可以不考虑词际界限就能做出来,但是也有许多话语的 IC 分析就得考虑词际的界限。每一个词是一个成分这个原则有助于 IC 的分析。在第五节里,作者认为一个秸构体可以有两个以上的 IC,如 men|and|Women“男人和女人”就有三个 IC。此外,还可以有非连续的 IC,如 the English king“这个英国国王”可以分析成:English+the…king“英国+这个……国王”。在这一节里,作者规定了作为多直接成分和非连续成分的条件。在最后一节里,作者提出了“超音段语素”的问题,也就是在 IC 分析中对音渡、重音和音高如何处理的问题。作者主张把音渡、重音和音高都当作语素,但不同意把对立重音看成语素。例如,bláckbird“画眉”跟 black bírd“黑色的鸟”的不同,在作者看来不是语素上的不同,而是结构上的不同。在标音上,作者主张把音渡语素、重音语素和音高语素跟音段语素一样都处理成线性的,也就是把超音段语素跟音段语素并列起来。

Enhancement of oxygen reduction activity and stability via introducing acid-resistant refractory Mo and regulating the near-surface Pt content

Although Pt Ni catalyst possesses good oxygen reduction activity, its poor stability is the main obstacle for the commercialization of proton exchange membrane fuel cells(PEMFCs). In this work, we introduce the acid-resistant refractory Mo to enhance the structure stability and modify the electronic structure of Pt in the prepared PtNi catalyst, improving the catalytic activity for oxygen reduction reaction(ORR). In addition, near-surface Pt content in the nanoparticle is also optimized to balance the ORR activity and stability. The electrochemical results show that the alloy formed by Mo and Pt Ni is obviously more stable than the PtNi alloy alone, because the acid-resistant Mo and its oxides effectively prevent the dissolution of Pt. Especially, the Pt3 Ni3 mon/C exhibits the optimal ORR catalytic performance in O2-saturated 0.1 mol L^(-1) HClO4 aqueous solutions, with mass activity(MA) of 900 m A mg^(-1) Pt at 0.90 V vs. RHE, which is 3.75 times enhancement compared with the commercial Pt/C(240 mA mg^(-1) Pt). After 30 k accelerated durability tests, its MA(690 m A mg^(-1) Pt) is still 2.88 times higher than the pristine Pt/C. This study thus provides a valuable method to design stable ORR catalysts with high efficiency and has great significance for the commercialization of PEMFCs.

Objective: To identify lateralizing features during seizures in infants and as sess their reliability. Methods Infants were included if they had video EEG mon itoring at our institution, and were seizure free for at least 12 months after epilepsy surgery. Lateralizing signs and seizure symptomatology were classified based on blinded video review. Results We analyzed 100 seizures from 19 infants (1 to 32, mean 13 months of age) (1 to 14 seizures per patient). Potential later alizing signs were seen in 58 seizures from 12 infants, including unilateral clo nic jerking (8 patients); forced, sustained tonic version of the eyes to one sid e (7 patients); predominantly unilateral infantile spasms (5 patients); unilater al tonic stiffening of an arm and leg (2 patients); nystagmus (2 patients) and p ostictal hemiparesis (1 patient). Except for tonic eye version, each of the sign s was contralateral to the hemisphere of seizure onsetin all but one patient wh o had predominantly ipsilateral spasms and clonic arm activity. Tonic eye versio n was contralateral in 3 patients, ipsilateral in 1 patient, and toward either s ide in different seizures in 3 patients. Conclusion Reliable lateralizing signs included focal clonic activity and predominantly unilateral spasms. Focal tonic activity, nystagmus and postictal hemiparesis were also consistently contralater al but were observed only in few patients. Tonic eye version was unreliable and could not beused to lateralizeseizure onset. The sequence of eye and head version evolvi ng to generalized tonic clonic convulsions was not seen in this age group.
