Mechanisms, prevention and clinical implications of nonsteroidal anti-inflammatory drug-enteropathy

引用

World Journal of Gastroenterology 2013年第12期19卷 1861-1876页

作者： John L wallace Farncombe Family Digestive Health Research Institute McMaster University Inflammation Research Network University of Calgary

This article reviews the latest developments in understanding the pathogenesis, detection and treatment of small intestinal damage and bleeding caused by nonsteroidal anti-inflammatory drugs (NSAIDs). With improvements in the detection of NSAID-induced damage in the small intestine, it is now clear that this injury and the associated bleeding occurs more frequently than that occurring in the stomach and duodenum, and can also be regarded as more dangerous. However, there are no proven-effective therapies for NSAID-enteropathy, and detection remains a challenge, particularly because of the poor correlation between tissue injury and symptoms. Moreover, recent studies suggest that commonly used drugs for protecting the upper gastrointestinal tract (i.e., proton pump inhibitors) can significantly worsen NSAID-induced damage in the small intestine. The pathogenesis of NSAID-enteropathy is complex, but studies in animal models are shedding light on the key factors that contribute to ulceration and bleeding, and are providing clues to the development of effective therapies and prevention strategies. Novel NSAIDs that do not cause small intestinal damage in animal models offer hope for a solution to this serious adverse effect of one of the most widely used classes of drugs.

Some Remarks on the Boundedness and Convergence Properties of Smooth Sliding Mode Controllers

引用

International Journal of Automation and computing 2009年第2期6卷 154-158页

作者： wallace Moreira Bessa Federal University of Rio Grande do Norte Department of Mechanical Engineering

Conventional sliding mode controllers are based on the assumption of switching control, but a well-known drawback of such controllers is the chattering phenomenon. To overcome the undesirable chattering effects, the discontinuity in the control law can be smoothed out in a thin boundary layer neighboring the switching surface. In this paper, rigorous proofs of the boundedness and convergence properties of smooth sliding mode controllers are presented. This result corrects flawed conclusions previously reached in the literature. An illustrative example is also presented in order to confirm the convergence of the tracking error vector to the defined bounded region.

Parrondo's paradox for chaos control and anticontrol of fractional-order systems

引用

Chinese Physics B 2016年第1期25卷 507-513页

作者： Marius-F Danca wallace K S Tang Department of Mathematics and Computer Science Avram Iancu University Romanian Institute for Science and Technology Department of Electronic Engineering City University of Hong Kong

We present the generalized forms of Parrondo＇s paradox existing in fractional-order nonlinear systems. The gener- alization is implemented by applying a parameter switching （PS） algorithm to the corresponding initial value problems associated with the fractional-order nonlinear systems. The PS algorithm switches a system parameter within a specific set of N 〉 2 values when solving the system with some numerical integration method. It is proven that any attractor of the concerned system can be approximated numerically. By replacing the words ＂winning＂ and ＂loosing＂ in the classical Parrondo＇s paradox with ＂order＂ and ＂chaos＂, respectively, the PS algorithm leads to the generalized Parrondo＇s paradox： chaos1 ＋ chaos2 ＋..- ＋ chaosN = order and order1 ＋ order2 ＋.-. ＋ orderN = chaos. Finally, the concept is well demon- strated with the results based on the fractional-order Chen system.

作者： Jessica wallace Tracey Covassin Meghan Lafevor Department of Kinesiology Michigan State University Human Performance & Exercise Science Department Youngstown State University

Purpose: The purpose of this study was to determine whether practicing athletic trainers(ATs) were using the stepwise progression to make return-to-play(RTP) decisions after concussion and to determine what factors influenced their decision to use the stepwise ***: A total of 166 ATs(response rate = 16.6%) completed a 21-item questionnaire that evaluated participant demographics, methods of concussion management, and RTP decision-making using the stepwise progression. Descriptive statistics and a logistic regression were completed to analyze ***: Factors such as education level(p = 0.05) and number of concussions treated(p = 0.05) predicted use of the stepwise progression,whereas sex(p = 0.17), employment setting(p = 0.17), state law(p = 0.86), and years practicing(p = 0.17) did not predict whether ATs were following the stepwise ***: The majority of the ATs from this study are employing the stepwise progression to safely return athletes to play after sustaining a concussion. This demonstrates that ATs are providing a standard of care for concussed athletes across various athletic training settings; however,having a graduate degree and treating more concussions per year are predictors of whether an AT follows all steps of the stepwise progression.
