1Weaning stress and gastrointestinal barrier development:Implications for lifelong gut health in pigs显示文摘The gastrointestinal(GI) barrier serves a critical role in survival and overall health of animals and humans. Several layers of barrier defense mechanisms are provided by the epithelial, immune and enteric nervous systems. Together they act in concert to control normal gut functions(e.g., digestion,absorption, secretion, immunity, etc.) whereas at the same time provide a barrier from the hostile conditions in the luminal environment. Breakdown of these critical GI functions is a central pathophysiological mechanism in the most serious GI disorders in pigs. This review will focus on the development and functional properties of the GI barrier in pigs and how common early life production stressors, such as weaning, can alter immediate and long-term barrier function and disease susceptibility.Specific stress-related pathophysiological mechanisms responsible for driving GI barrier dysfunction induced by weaning and the implications to animal health and performance will be discussed.Adam J.Moeser Calvin S.Pohl Mrigendra Rajput 2017Animal Nutrition2017,,4:33
2乙型肝炎病毒母婴传播及其阻断研究的现状与存在问题显示文摘HBV可经血液、母婴、性接触等多种途径传播,其中母婴传播是我国HBV传播的主要途径之一.乙型肝炎母婴阻断是指通过产前、产时,产后采取一系列措施对新生儿进行保护以减少感染HBV机会的方法.近年来,HBV的母婴阻断取得了较好效果,总体阻断成功率约在90%以上,但仍有一定的失败率,在相关机制、方案优化等方面仍面临一些亟待解决的问题.邹怀宾 陈煜 张华 段钟平 李杰 庄辉 梁晓峰 Calvin Q.Pan 2010中华肝脏病杂志2010,18,7:18

7A review of the geomechanics aspects of a double fatality coal burst at Austar Colliery in NSW,Australia in April 2014显示文摘A coal burst occurred on 15 April, 2014 at the Austar Coal Mine, located west of Newcastle, NSW,Australia. The burst resulted in fatal injuries to two men working as part of the mining crew at the development face. At the time, a continuous miner was being used to mine a longwall development gate road through heavily structured coal, at a depth of approximately 550 m. A number of pre-cursor bumps had occurred on previous shifts, emanating from the coal ribs of the roadway, in proximity to the coal face.This paper reviews the geological, geotechnical and mining conditions and circumstances leading up to the coal burst event; and presents and discusses the available evidence and possible interpretations relating to the geomechanical behaviour mechanisms that may have been critical factors in this incident. The paper also discusses some key technical and operational considerations of ground support systems and mining practices and strategies needed for operating in such conditions in the future.Hebblewhite Bruce Calvin Jim 2017International Journal of Mining Science and Technology2017,27,1:11

16A classification system for tableting behaviors of binary powder mixtures显示文摘The ability to predict tableting properties of a powder mixture from individual components is of both fundamental and practical importance to the efficient formulation development of tablet products. A common tableting classification system(TCS) of binary powder mixtures facilitates the systematic development of new knowledge in this direction. Based on the dependence of tablet tensile strength on weight fraction in a binary mixture,three main types of tableting behavior are identified. Each type is further divided to arrive at a total of 15 sub-classes. The proposed classification system lays a framework for a better understanding of powder interactions during compaction. Potential applications and limitations of this classification system are discussed.Changquan Calvin Sun 2016Asian Journal of Pharmaceutical Sciences2016,11,4:3
