Learning surgically oriented anatomy in a student-run extracurricular club: an education through recreation initiative

Didactic and laboratory anatomical education have seen significant reductions in the medical school curriculum due, in part, to the current shift from basic science to more clinically based teaching in North American medical schools. In order to increase medical student exposure to anatomy, with clinical applicability, a student-run initiative called surgically oriented anatomy prosectors (SOAP) club was created within the extracurricular program at the Schulich School of Medicine and Dentistry, The University of Western Ontario, London, Canada. SOAP invites surgeons and residents from various surgical specialties to demonstrate, on a cadaver, a surgical procedure of their choosing. During the demonstration, the anatomy, as it relates to the surgical procedure, is discussed. The students then break into smaller groups to examine the relevant anatomy on the cadavers, during which time the discussion is broadened. The group continues the conversation in a social environment with refreshments. SOAP is one of the most popular extracurricular clubs with 65% of first and second year medical students registered as members. The high demand for SOAP, along with the positive participant feedback, may be due to its utilization of the principle of education through recreation, which seeks to provide opportunities for learning seamlessly throughout all facets of life. It also demonstrates the desire, amongst certain medical students, to learn applied anatomy, particularly within a surgical context.     

Effect of a semi electro-mechanical engine valve on performance and emissions in a single cylinder spark ignited engine

In this study, an electro-mechanical valve （EMV） system for the intake valve ofa fottr stroke, single cylinder, overhead valve and spark ignition （SI） engine was designed and constructed. An engine with the EMV system and a standard engine were tested to observe the effects of the EMV on engine performance and emissions at different speeds under full load. The EMV engine showed improved engine power, engine torque and break specific fuel consumption （BSFC）. A 66% decrease in CO emissions was also obtained with the EMV system, but hydrocarbons （HC） and NOx emissions increased by 12% and 13% respectively.     

俄罗斯第三代高等教育国家标准:背景、框架、特点

俄罗斯第三代高等教育国家标准的核心是对基础教育大纲的掌握结果、结构和实施条件提出的要求。该标准的制定以能力素养观为基础,要求培养学生的一般文化能力素养和职业能力素养,目标指向以学生发展为本和跨学科能力的培养。基础教育大纲中三类学科的课程分为国家统一设置的基础部分和高校自主设置的可变部分,体现了统一性与自主性相结合的原则。新标准实施的瓶颈是能力要素结构的构建和能力评价。

关于广播多功能和运作机制问题的思考

1992年以来,新疆广播界以大板块、大时段、大容量的主持人直播和开办专业台、系列台为特征的广播宣传改革,引起广大听众的积极参与。广播在与电视、报刊等多种传媒的竞争中焕发生机,呈现出广阔的发展前景。 但是,广播也面临着如何适应建立社会主义市场经济体制新形势,进一步深化改革的新课题。其中,对广播的多功能和运作机制的进一步明确和统一认识已成为广播改革能否深入推进的关键问题。笔者对此谈一点粗浅的看法。 一、关于广播的主功能、服务功能和产业功能问题     

社会经济形态

现代世界革命运动和民族解放运动的发展证明,关于经济形态的学说不仅具有理论意义,而且具有实践意义。同这个那个国家对社会发展道路的选择和实现某些社会改造联系在一起的许多非常实际的问题的解决,都在某种程度上取决于对社会经济形态发挥

Fabrication of a gel particle array in a microfluidic device for bioassays of protein and glucose in human urine samples

This paper describes a simple method for fabricating a series of poly(ethylene glycol) diacrylate (PEG-DA) hydrogel microstructures inside microfluidic channels as probe for proteins and glucose. In order to demonstrate the feasibility of this newly developed system, bovine serum albumin (BSA) was chosen as a model protein. PEG microcolumns were used for the parallel detection of multiple components. Using tetrabromophenol blue (TBPB) and the horseradish peroxidase/glucose oxidase reaction system, bovine serum albumin (BSA) and glucose in human urine were detected by color changes. The color changes for BSA within a concentration range of 1-150 μM, and glucose within a range of 50 mM-2 M could be directly distinguished by eyes or precisely identified by optical microscope. To show the practicability of the gel particle array, protein and glucose concentrations of real human urine samples were determined, resulting in a good correlation with hospital analysis. Notably, only a 5 μL sample was needed for a parallel measurement of both analytes. Conveniently, no special readout equipment or power source was required during the diagnosis process, which is promising for an application in rapid point-of-care diagnosis.     

The microfluidic system for studies of carcinoma and normal cells interactions after photodynamic therapy (PDT) procedures

This study reports on the use of a microsystem for evaluation of photodynamic therapy (PDT) procedures on the "mixed" (carcinoma-normal) cultures. Balb/3T3 (normal mouse embryo) and A549 (human lung carcinoma) cells were tested in separated and "mixed" cultures. Interactions and migration of cells cultured together were observed. The PDT procedures were examined in the hybrid (PDMS/glass) microsystem which contains cell culture microchambers integrated with network of microchannels. We investigated that the number of dead cells after PDT procedures is dependent on the kind of cell culture. Moreover, the influence of the carcinoma cells on the viability of normal cells in the "mixed" culture was observed.
