与使用无机矿物质相比,在猪饲料中添加有机矿物质可给养猪生产各个阶段的生产性能和环境带来益处。由于有机矿物质具有较好的养分利用率,因此它不仅能使猪的生产性能不受影响,而且还能使养猪生产的净收益得到提高。

本文提出了一种简便的对全球植被进行分类的新方法。该方法的特色是:它是以植被结构的简单的、看得到的、明确的特征为基础进行分类的,这些特征对生物地球化学系统来说是很重要的,并且可在野外实测验证。由于植被结构的特征可以用遥感方法确定,所以就有可能对全球现有植被反复地、有效地重新分类,并把所定义的植被类型通过全球气候和生物地球化学模型直接转换成所需要的生物物理参数。本文给出了这种推理方法在美国大陆上的第一次验证结果,这是在现有的分辨率为1km的标准差植被指数数据库的基础上进行的。通过附加气候描述因子,并对六种基本植被类型进行合理综合,就可以很容易地从这种分类方法推论出目前得到认可的全球生物群落类型。

Effects of three controlled mechanical ventilation modes on rat lung hydrogen peroxide and apoptosis during hemorrhagic shock

引用

Open Journal of Molecular and Integrative Physiology 2013年第1期3卷 27-35页

作者： Amanda R. Thimmesch Qiuhua Shen Richard l. Clancy Janet D. pierce School of Nursing University of Kansas Kansas City USA

Hemorrhagic shock causes a reduction in oxygen supply to tissues leading to increased reactive oxygen species resulting in lung injury. Often mechanical ventilation is required as supportive treatment;however, ventilation can also induce lung injury and apoptosis. The purpose of this study was to examine the effects of three modes of controlled mechanical ventilation: volume control, pressure control, and pressure regulated volume control on lung injury as measured by hydrogen peroxide and apoptosis during hemorrhagic shock. Male Sprague-Dawley rats were randomized to the three controlled mechanical ventilation groups. Hemorrhagic shock was elicited by removing approximately 40% of the blood volume over 30 minutes. The rats were treated with one of three modes of mechanical ventilation with 40% oxygen for 60 minutes. The lungs were removed and measured for hydrogen peroxide and apoptosis based on nuclear differential dye uptake. There were no significant differences in hemodynamics, arterial blood values, peak inspiratory pressures, tidal volume, respiratory rates, and intrathoracic pressures across three groups. However, lung hydrogen peroxide production and apoptosis were significantly increased in volume control and pressure control, compared to pressure-regulated volume control. In this study, early signs of ventilator induced lung injury were not detected using commonly employed clinical measurements. However, when examining lung cellular injury (hydrogen peroxide and apoptosis), we were able to measure significant lung damage in volume control and pressure control, but not pressure-regulated volume control. Thus, our results suggest that pressure-regulated volume control is the preferable mode of mechanical ventilation during hemorrhagic shock.

欧盟最近列家禽日粮中的微量元索如铜、锌和铁等做了新的规定。由于这些元素在粪便中的排泄量水平较高,欧盟对其在日粮中的允许添加量设立了更低的标准。本篇文章回顾了一项关于家禽的研究试验,以评估饲喂较低浓度的有机微量元素的效果。研究的主要目的是在维持正常生产性能的前提下,尽可能降低微量元素的排泄量。研究结果表明,可以以较低水平给畜禽提供生物利用率更高的微量元素,从而显著减少排泄量,并且不会对其生长性能产生任何不利影响。
