    Description / Table of Contents: Introduction -- Gut microbiota and alimentary tract injury -- Gut microbiota and liver injury - Acute liver injury -- Gut microbiota and liver injury - Chronic liver injury -- Gut microbiota and lung injury -- Gut microbiota and brain injury -- Gut microbiota and renal injury -- Gut microbiota and heart, vascular injury -- Gut microbiota and endocrine disorders -- Gut microbiota and immune responses -- Gut microbiota and multiple organ dysfunction syndrome (MODS).
    Abstract: This book aims to introduce the latest research in gut microbiota by systematically summarizing how it modulates the pathogenesis of organ injury including alimentary tract injury, liver injury, lung injury, brain injury, renal injury, heart and vascular injury, endocrine disorders, immune responses and multiple organ dysfunction syndrome (MODS) during sepsis. Gut microbiota which is recognized as a new “organ” in the body has been demonstrated to be able to regulate the homeostasis of many organs. The key role played by gut microbiota is the hotspot in biomedical research nowadays. This book provides a state-of-the-art report on recent discoveries regarding the novel insight into the mechanisms of human diseases progression. It will also offer the overall picture of the pathophysiologic roles of gut microbiota. This book is helpful for graduate students and professional researchers to get the knowledge of frontiers in both gut microbiota and organ injury.

    Notes: Creep properties of polymer bonded explosives (PBXs), a particulate composite, wasstudied by using the method of moiré interferometry in this paper. The specimens fabricated bydifferent heat pressing technology were used. Extensive creep deformation of PBXs material wasindirectly measured by the aid of compressive circular disk test. The obtained results shown that creepproperties are greatly influenced by pressing pressures and temperature of heat pressing technology.The results indicated that the higher the temperature and the pressing pressure are in the heat pressingtechnology to some degree, the better the PBXs material creep resistance is. The creep fracturesurfaces of PBXs were also observed using Scanning Electronic Microscopy (SEM). It was shownthat most of the fracture crack was initiated and propagated along the explosives crystal surfaceduring creep

    Notes: The spider silk is considered as a new type of biomaterials with its excellent mechanicalproperties. The mechanical properties of the spider silk are crucial to their applications. In this studythe mechanical properties of spider silk were studied with a micro-tensile system driven bymagnet-coil force actuator, which is very effective to measure the properties of low dimensionalmaterials. The Young’s modulus of the spider silk is obtained, the relationship between themechanical properties of spider silk and time is also acquired

    Notes: In this paper, a novel nano-moiré grating fabrication technique was proposed fornanometer deformation measurement. The grating fabrication process was performed with the aidof Atomic Force Microscope (AFM) on the basis of micro-fabrication technique. On the analysis ofsome correlative factors of influencing grating line quality, some important experimentalparameters were optimized. In this study, some parallel and cross nano-gratings with frequencies offrom 10000lines/mm to 20000lines/mm were fabricated. The successful experimental resultsdemonstrate that the nano-grating fabrication technique is feasible and also indicated that thesenano-gratings with nano-moiré method can be applied to deformation measurement, which offers ananometer sensitivity and spatial resolution

    Notes: In this study, the digital image correlation method(with Newton-Raphson iterationmethod) is used to measure the in-plane deformation of poly-crystal aluminum. When the specimenis exerted a tensile load, the strain distribution of the specimen surface will be inhomogeneous. Themicro-deformation of the poly-crystal aluminum is studied under a SEM(scanning electronmicroscope), a series of images of the micro crystal are captured during the loading process. Byusing digital image correlation to analyze the images, the displacement and strain of a micro-crystalare obtained, which provide important data for further analysis of the inhomogeneous properties ofthe poly-crystal aluminum

    Notes: Martensitic phase transformation can greatly affect the mechanical behaviors and thestress-strain response of shape memory alloys (SMAs). In this study, the effect of martensitic phasetransformation on the deformation of a single-crystal TiNi SMA specimen with a triangle crack wasinvestigated experimentally by means of moiré interferometry method. A typical displacement fieldand the corresponding strain field in areas both around and far from the tip of the crack were measuredin a certain time during the loading process in which the tensile load is coupled with thestress-induced martensitic phase transformation. Some characteristics of the deformation and themartensitic phase transformation of the specimen are revealed. These results may provide a reliablesupport for revealing the fracture mechanism of single crystal TiNi SMAs, and may enable furtherdevelopment in putting forward the failure criterion of SMAs

    Notes: Manifold Method provides a unified framework for solving problems with bothcontinuous and discontinuous media. In this paper, by introducing a criterion of crack initiation andpropagation, the second order manifold method is used to simulate two-hole blasting andHopkinson spalling of rock. In the study of two-hole blasting, two different initiation conditions areconsidered. One is simultaneous initiation, the other is 0.1 ms delay initiation. The whole blastingprocess including crack initiation, crack growth and fragment formation is simulated. In the study ofHopkinson spalling, the propagation and interaction of stress waves and the spalling process causedby a reflected tensile stress wave are reproduced. The simulation results including the thickness ofthe formed scab and its velocity are in good agreement with theoretical values. Manifold methodproves to be an efficient method in the study of dynamic fracture of rock

    Notes: In support of the spiral wave theory of reentry, simulation studies and animal models have been utilized to show various patterns of spiral wave tip motion such as meandering and drifting. However, the demonstration of these or any other patterns in cardiac tissues have been limited. Whether such patterns of spiral tip motion are commonly observed in fibrillating cardiac tissues is unknown, and whether such patterns form the basis of ventricular tachycardia or fibrillation remain debatable. Using a computerized dynamic activation display, 108 episodes of atrial and ventricular tachycardia and fibrillation in isolated and intact canine cardiac tissues, as well as in vitro swine and myopathic human cardiac tissues, were analyzed for patterns of nonstationary, spiral wave tip motion. Among them, 46 episodes were from normal animal myocardium without pharmacological perturbations, 50 samples were from normal animal myocardium, either treated with drugs or had chemical ablation of the subendocardium, and 12 samples were from diseased human hearts. Among the total episodes, 11 of them had obvious nonstationary spiral tip motion with a life span of 〉2 cycles and with consecutive reentrant paths distinct from each other. Four patterns were observed: (1) meandering with an inward petal flower in 2; (2) meandering with outward petals in 5; (3) irregularly concentric in 3 (core moving about a common center); and (4) drift in 1 (linear core movement). The life span of a single nonstationary spiral wave lasted no more than 7 complete cycles with a mean of 4.6±4.3, and a median of 4.5 cycles in our samples. Conclusion: (1) Patently evident nonstationary spiral waves with long life spans were uncommon in our sample of mostly normal cardiac tissues, thus making a single meandering spiral wave an unlikely major mechanism of fibrillation in normal ventricular myocardium. (2) A tendency toward four patterns of nonstationary spiral tip motion was observed. © 1998 American Institute of Physics.
