Background: Postpartum inflammation is a natural and necessary response;however, a dysfunctional inflammatory response can be detrimental to animal productivity. The objective of this study was to determine the effects of a non-steroidal anti-inflammatory drug(meloxicam) on ewe postpartum inflammatory response, ewe plasma polyunsaturated fatty acid and oxylipid concentrations, and lamb ***: After lambing, 36 hampshire and hampshire × Suffolk ewes were sequentially assigned within type of birth to control(n = 17) or meloxicam orally administered on d 1 and 4 of lactation(MEL;90 mg, n = 19). Milk and blood samples were collected on d 1(prior to treatment) and d 4. Milk glucose-6-phosphate was not affected by MEL. Plasma haptoglobin(hp) concentrations were less for MEL ewes;control ewes with greater d 1 hp concentrations had elevated hp on d 4, but this was not the case for MEL-treated ewes. Treatment with MEL increased plasma arachidonic acid concentration by more than 4-fold in ewes rearing singles but decreased concentrations of 9,10-dihydroxyoctadecenoic acid, prostaglandin F2α, 8-iso-prostaglandin E2, and 8,9-dihydroxyeicosatetraenoic acid. Nine oxylipids in plasma had interactions of treatment with d 1 hp concentration,all of which revealed positive associations between d 1 hp and d 4 oxylipid concentrations for CON, but neutral or negative relationships for MEL. MEL decreased 13-hydroxyoctadecadienoic acid:13-oxooctadecadienoic acid ratio and tended to increase 9-hydroxyoctadecadienoic acid:9-oxooctadecadienoic acid ratio(both dependent on d 1 values), indicating progressive metabolism of linoleic acid-derived oxylipids occurred by enzymatic oxidation after MEL treatment. Meloxicam reduced oxylipids generated across oxygenation pathways, potentially due to an improved redox ***: Postpartum MEL treatment of ewes decreased plasma concentrations of hp and several oxylipids,with the greatest impact in ewes with biomarkers reflecting a greate

引言西欧家用洗涤剂市场日趋饱和,洗涤剂原料消耗趋势缓慢上升,而助剂例外,它确实需要非寻常的预见能力预测这十年来的状况。产品的包装使我们相信,洗涤产品配方正不断经历根本性变化。当然,事实并非如此,近几年已看到一些重要的新发展:合成纤维或混纺品大规模代替棉织品;节能的需求导致使用较低的洗涤温度;液体已部分取代粉状产品,最重要的是涉及水生环境的污染导致立法。

如果从青少年时就开始体育锻炼，能显著强化骨骼。在骨骼生长过程中，运动通过增加骨外膜并列（periosteal apposition）来增加负重骨结构，并且，骨量增加最大处常常是细胞外液流体静压最大处。这一发现提示细胞外液压或流体切应力对骨细胞的应激刺激骨形成。使骨量增另的最好运动是对骨骼的冲力负荷。然而，最近的前瞻性研究表明即使是冲力性运动对成人骨量增加也并非十分秦效，并且还增加老年人骨关节炎危险。因此人们可能疑问是否应该鼓励冲力性运动来预防骨质疏松。作为替代，代冲击力性运动可以作为预防骨质疏松的首选运动方案，以改善肌肉强度和平衡能力。低冲击力性运动方案的目的是预防跌倒，而不是增加骨量。介导作用于骨的机械负荷的一些生化介质已经明确，其中前列腺素族和一氧化氮最重要。此外，甲状旁腺素和生长激素对骨的机械传导提供信号。最后，对小鼠近交株的研究提示骨对机械负荷的反应能力受遗传控制。学习目的：回顾运动增强骨骼的机制；何种运动最佳，何种运动方式可减少或抵消冲力性运动的副作用？思考激素和一些药物如何影响运动对骨骼的作用。

调查1973年棉花品种区域试验种植在17个地点的4个陆地棉品种的种子和纤维样本,以便了解产量、种子品质和纤维品质。计算8种农艺和品质参数间的相关系数。产量和油分含量或产量和蛋白质含量间都没有发现显著性相关。4个品种内3个,在油分含量和纤维成熟度间表现为正相关,在油分分量和未成熟种子百分数间为负相关。就蛋白质说,和纤维成熟度的负相关最显莱。洛盖特4789A 的油分含量和籽指间为高度正相关。爱字棉1517—70的蛋白质和纤维成熟度间为高度负相关。这两个品种在产量和纤维强度间都表现正相关。现在讨论利用气流细度测定仪读数(纤维成熟度)作为不同生产地区棉子油分含量指标的可实行性。
