  A Demonstration of Postpellet Application of Dry Phytase to Broiler Diets

  摘要：

  A comparison of performance and P reduction in litter and manure from broilers fed rations with and without phytase enzyme was made with chickens reared on litter or in cages. Low-activity phytase supplemented as a dry powder to mash diets did not affect performance, but litter P accumulation was decreased 14 to 21% during the starter and grower phases. Liquid phytase applied postpelleting to diets with 0.5% total P (0.3% available P) reduced litter P accumulation (14 to 19%) and reduced manure P content in starter, grower, and finisher phases of the study. Phosphorus content in raw manure was decreased by 55% during the finisher phase. Feed conversions of broliers in cages and on conventional litter-covered floors were improved significantly with postpellet application of liquid phytase. Feed conversion improvement was greater in birds in cages. Postpellet application of dry phytase was shown to be feasible based upon performance and reduction in litter P accumulation. Feed conversions were improved by 7 to 8 points (P < 0.05) when compared to those of birds given a normal P level (0.72% total P) diet without phytase. Litter P accumulation was reduced between 20.5 and 28.5% with dry phytase applied postpelleting. With liquid phytase applied postpelleting, litter P accumulation was reduced 26.6% These reductions in litter P content represent about 4 lb of P per ton of litter.

  An Unusual Presentation of Tarsal Tunnel Syndrome Caused by an Inflatable Ice Hockey Skate

  摘要：

  背景：跗骨隧道综合征是一种罕见的局限性神经病。在运动员中，它通常是重复性活动、局部损伤或空间占位性病变的结果。方法：对一名 37 岁的男性休闲曲棍球运动员进行了临床和电生理学检查，原因是他在打曲棍球时左脚脚趾麻木，而他穿的充气冰上曲棍球冰鞋是为了更好地贴合脚部。混合性和运动性足底神经反应的振幅减小，并伴有颤动电位和正尖波，没有传导阻滞的证据，这表明主要病理变化是轴索缺失。随访检查显示，患者在停止穿着充气冰球冰鞋后，临床和电生理状况均有明显改善。结论：我们报告了一例因冰上曲棍球充气冰鞋引起的不寻常的跗骨隧道综合征，患者在停穿该冰鞋后，临床症状和电生理症状均有所改善。

  The mass spectral behaviour of α,ω-disubstituted alkanes and, especially, that of different N-substituted α,ω-diaminoalkanes has been investigated. It was found that the two amino groups which are separated by CH2-groups can fragment only to a small extent indepently from each other. Yet those fragmentation reactions are predominant in which both functional groups participate. The main reactions of

  [reaction: see text] Pretreatment of a symmetrical primary or secondary diamine with 9-BBN prior to the addition of an acyl chloride significantly suppressed undesired diacylation, and the product of monoacylation predominated. The reactive preference is interpreted as the result of a selective deactivation of one nitrogen atom of the diamine by 9-BBN.

  [反应：见正文]在添加酰氯之前，用9-BBN预处理对称的伯或仲二胺会显着抑制不希望的二酰化作用，并且单酰化产物占主导地位。反应性偏爱被解释为二胺的一个氮原子被9-BBN选择性失活的结果。

  isolation procedure is simple, environmentally friendly, and is performed with no need for chromatographic purification of secondary amides due to high yields. In this report, primary amines were used in most examples. However, the developed procedure seems to be applicable for secondary amines as well. The methodology produces a limited amount of wastes, and a catalyst can be easily separated. This highly

  酰胺键是化学制药工业中最有趣和最丰富的生命分子和产品之一。在这项工作中，我们描述了一种在无溶剂条件下使用微量硝酸铈铵 (CAN) 作为催化剂从羧酸和胺直接合成酰胺的方法。该反应在开放式微波反应器中进行，与迄今为止文献中报道的由酸和胺直接合成酰胺的其他方法相比，可以快速有效地获得相应的酰胺。酰胺产物的分离过程简单、环保，并且由于产率高，不需要二级酰胺的色谱纯化。在本报告中，大多数实施例中使用了伯胺。然而，开发的程序似乎也适用于仲胺。该方法产生的废物量有限，而且催化剂很容易分离。这种高效、稳健、快速、无溶剂和额外无试剂的方法为开发理想的酰胺键形成绿色方案提供了重大进步。
