Age, sex, activity, genetic phenotype, stress, disease （eg, achlorhydria, malabsorption syndromes）, or previous GI surgery can affect drug bioavailability.

年龄、性别、活动情况、遗传表型、应激、疾病（如胃酸缺乏，营养不良综合征）或既往胃肠手术等均能影响药物的生物利用度。

Age, sex, activity, genetic phenotype, stre , disease （eg, achlorhydria, mala orption syndromes）, or previous GI surgery can affect drug bioavailability.

The results showed the characteristics of Artemia strain were not changed from 2000 to 2002, which is not the factor caused the decline of the cyst production; however, serious deficiency of nitrogen and phosphorus in the ponds was the main factor, which result in the decline of the cyst production year by year.

实验结果表明：卤虫的品系特性2年内未有变化，不是造成卤虫卵产量下降的主要因素；池子中氮、磷营养的缺乏才是卤虫卵产量下降的主要原因。

铁缺乏是世界范围内最常见的营养不良[1]，据世界卫生组织1997年估计，世界上有40~50亿人处于铁缺乏的状态，占世界总人口的66%~80%，其中有20亿人即超过30%的人患有贫血。

There are several factors that can increase the chances of your tortoise getting RNS - dusty conditions, foreign bodies lodging in the nostrils, inappropriate humidity or temperature, lack of sunlight and the accompanying dampness, confinement in damp grassed areas with no access to sand, overcrowding, malnutrition, stress, and a deficiency of vitamin A.

有些因素会增加患RNS的几率：充满灰尘的环境，鼻孔处的外来寄生物，不合适的温度或湿度，缺乏日晒和相应的潮气，关在潮湿的草丛里，不能接触到沙地，过渡拥挤的环境，营养失调，过分紧张，缺乏维生素A。

The cause of hindering the gynospore formation was short of boronin chestnut orchard,which led to the poor pollination and a decrease ofendogenous GA1/3, iPAs level and an increase of endogenous ABA level in ovary,which restrained the mother cell division of gynospore.The low level ofendogenous GA1/3,iPAs contents and the increase of endogenous ABA contentcaused a serious lack of reducing sugar,starch,protein and potassium in ovary,which led to a cease of young embryo development.

其中，大孢子形成过程的停滞是由于栗园B素缺乏，致使授粉不良和子房内源GA1/3、iPAS等含量下降，ABA含量上升，从而抑制大孢子母细胞分裂；幼胚发育停滞则是由于子房内源GA1/3、iPAS等生长类激素的上升启动受阻，继续处于低水平，ABA上升，使子房中还原糖、淀粉、蛋白质和K素积累受阻，造成营养严重缺乏。

In addition, it also leads to the increase of T〓 and FT〓 content, the decrease of T〓 and FT〓 content, the increase of TSH content in the plasma, which seriously influences the whole body's growth and metabolism of nutrimental materials and is one of the mechnism of nutritional anemia that is caused by lack of matter of making blood.

首次揭示雏鸡硒缺乏不但对甲状腺造成损伤，而且还特异性地降低肝脏、肾脏等组织中ID-1活性，使血浆3-5-3'-5'-四碘甲状腺原氨酸、游离T〓含量升高，3-5-3'-三碘甲状腺原氨酸、游离T〓含量下降，促甲状腺激素含量升高，严重影响整个机体的生长发育及营养物质代谢，并是导致造血物质缺乏所致的营养性贫血的机理之一。

Controlled-release boluses are applied to ruminant animal so that the influence of bolus on the status of MDA, Cu-Zn-SOD and GSH-Px in plasma and the cha.

本研究在对青海牧区环境、牧草微量元素含量以及放牧反刍家畜体组织微量元素缺乏的情况作资料调查的前提下，有针对性的选择在青海牧区普遍缺乏的硒、钴、铜和锌这四种微量元素制成微量元素营养缓释弹丸。

Lack of consumer demand and questionable nutritional benefit led to gradual phasing out these enrichments.

消费者需求缺乏以及在营养价值方面疑问最终让营养添加剂慢慢的推出了市场
