Herbal medicine in the treatment of liver diseases
No full textHerbal drugs have become increasingly popular and their use is widespread. Licensing regulations and pharmacovigilance regarding herbal products are still incomplete and clearcut proof of their efficacy in liver diseases is sparse. Nevertheless, a number of herbals show promising activity including silymarin for antifibrotic treatment, phyllantus amarus in chronic hepatitis B, glycyrrhizin to treat chronic viral hepatitis, and a number of herbal combinations from China and Japan that deserve testing in appropriate studies. Apart from therapeutic properties, reports are accumulating about liver injury after the intake of herbals, including those advertised for liver diseases. Acute and/or chronic liver damage occurred after ingestion of some Chinese herbs, herbals that contain pyrrolizidine alkaloids, germander, greater celandine, kava, atractylis gummifera, callilepsis laureola, senna alkaloids, chaparral and many others. Since the evidence supporting the use of botanicals to treat chronic liver diseases is insufficient and only few of them are well standardised and free of potential serious side effects, most of these medications are not recommended outside clinical trials. Particularly with regard to the latter, adequately powered randomised-controlled clinical trials with well-selected end points are needed to assess the role of herbal therapy for liver diseases
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Development of Imbedded Sensors and Techniques for Chloride Determinations in Steel Reinforced Bridge Deck Structures
No full textFaculty advisor: John F. EvansChloride ions, found in deicing chemicals, penetrate concrete causing corrosion of reinforcing steel. Corrosion in bridge deck and post-tensioned structures poses a great safety risk to the public. Furthermore, corrosion monitoring is very expensive. Time domain reflectometry is a method in which a high velocity pulse is sent down the length of a transmission line. Any imperfections along the line are reflected back, and the exact location of the imperfection can be determined. For our purposes, a sensor consisting of two parallel electrodes is placed at the end of a transmission line. The sensor is placed in differing chloride concentrations (0.1M, 0.5M, 1.0M NaCl) and reflected waveforms are analyzed and correlated using LabVIEW software. In our experiments, one electrode receives pulses from the time domain reflectometer (TDR) while the other electrode is held at ground. In order to study the initial redox chemistry of the electrodes, our focus has been on developing high-speed switching devices and software to accommodate the switches.This research was supported by the Undergraduate Research Opportunities Program (UROP).Stickel, Robert.

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
