That is not to undermine the importance of scientific knowledge, but there currently exists a major flaw in our high school educational system that inhibits meaningful learning experiences for most students. Application of science in local high schools is largely directed at improving performance on multiple-choice exams. Standardized tests taken by high school students are slowly progressing,展开更多

We are grateful to promote a cultural challenge toward a new horizon in the field of translational research (TR). We enjoy to work together with the common objective to perform continuous medical education programs, exploring the methods in research, designing study, and to improve multidisciplinary and multiprofessional collaboration in the basic sciences and in the clinical trials. Defined narrowly, epistemology is the study of knowledge and justified belief. Epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? What are its sources? What is its structure and what are its limits? More broadly, epistemology is about issues having to do with the creation and dissemination of knowledge in particular areas of inquiry as defined and revisiting at the beginning of the last decades. Translational medicine (TM) should meet the demands to maintain or expanding the biomedical workforce and education programs that attract and retain young people in the translational and biomedical sciences. With this present contributes, we invite the members of the editorial board of Burns & Trauma to encourage submitting, in a special section, their personal experience about the philosophy of "Translation research." If this has a chance, welcome to the researchers, clinicians, and the allied people for their decisive contributions to strengthen the importance of a common way about the principles and methods of basic and clinical research. TR and TM represent a dynamic entity making a link, a sort of bridge, "from bench to bedside", or from laboratory experiments through clinical trials to point-of-care patient applications. Epistemological pluralism is a critical point for conducting innovative, collaborative research which can lead to more successful integrated and successfully study, particularly important in the field of burns and trauma.展开更多

In oncology, translational research implies using our basic knowledge learnt from in vitro and in vivo experiments to directly improve diagnostic tools and therapeutic approaches in cancer patients. Moreover, the better understanding of human cancer and its use to design more reliable tumor models and more accurate experimental systems also has to be considered a good example of translational research. The identification and characterization of new molecular markers and the discovery of novel targeted therapies are two main goals in colorectal cancer translational research. However, the straightforward translation of basic research findings, specifically into colorectal cancer treatment and vice versa is still underway. In the present paper, a summarized view of some of the new available approaches on colorectal cancer translational research is provided. Pros and cons are discussed for every approach exposed.展开更多

The controllability of environmental conditions, the high reproducibility, the ease of scale and the comparability of results, as well as the ability to use different standards for ethical protocols, all make an animal model the ideal tool for carrying out studies on human diseases and the development of novel pharmaceuticals and new therapies （Xue et al., 2014）. An ideal animal model should reflect the complete spectra of a specific human disease, with similar features on the following key issues： （1） genetic basis; （2） anatomy and physiology; （3） pathological response（s） and underlying mechanism（s）; （4） phenotypic endpoints as clinical studies; （5） responsiveness to known drugs with clinical efficacy; and （6） prediction of clinical efficacy （McGonigle and Ruggeri, 2014）.展开更多

Translation on film and television drama subtitles plays a key role for cultural exchange. However, the quality of film and television translation is uneven, and the exploration of film and television translation is imperative.Subtitle translation is a special type of language conversion. From the theory of relevance, this paper analyzes the film Forrest Gump as a case, and sums up some feasible subtitle translation strategies. This paper aims at using reasonable theory to guide the translation of film subtitles, and improving the quality of translation.This article is composed of five parts, the first part is mainly introducing. The second part is an introduction to the theory of relevance. The third part is the subtitles translation of Forrest Gump. The fourth part is about the translation of film subtitles from the theory of relevance. The fifth part is a summary.展开更多

However, the quality of film and television translation is uneven, and the exploration of film and television translation is imperative.Subtitle translation is a special type of language conversion. From the theory of relevance, this paper analyzes the film Forrest Gump as a case, and sums up some feasible subtitle translation strategies. This paper aims at using reasonable theory to guide the translation of film subtitles, and improving the quality of translation.This article is composed of five parts, the first part is mainly introducing. The second part is an introduction to the theory of relevance. The third part is the subtitles translation of Forrest Gump. The fourth part is about the translation of film subtitles from the theory of relevance. The fifth part is a summary.

文摘Over 550000 people in the U.S.require hemodialysis for management of end stage renal disease(ESRD).When anatomy restricts fistula creation,arteriovenous grafts(AVG)are implanted.AVGs have poor primary patency and high risk of infection,highlighting a need for better alternatives.Previous AVG large animal models were limited by high complication rates and short-term follow-up.This study investigates the safety and durability of an ovine bilateral carotid-jugular AVG model.Eight female sheep underwent bilateral carotid-jugular AVG implantation via a single longitudinal incision overlying the trachea.Ringed PTFE grafts were anastomosed in a“lazy-S”configuration to provide the laxity needed to prevent avulsion and minimize kinking with neck movement.Post-operatively,sheep were evaluated daily to monitor for complications.Duplex ultrasonography of the grafts was performed at regular intervals out to 6 months to evaluate patency.At 6 months,angiography and duplex was performed followed by explant for gross and histologic analysis.Technical success was achieved in 16 of 16(100%)graft implants.No major complications,including stroke,anastomotic disruption,infection,wound breakdown,or death occurred.Primary patency of control PTFE grafts was 75%at 6 months,paralleling reported rates in humans.Bilateral carotid-jugular AVG implantation in sheep is a safe and durable model for self-controlled long-term evaluation of AVG conduit technology.
