Food Fish Identification from DNA Extraction Through Sequence Analysis

This experiment exposed 3rd and 4th y undergraduates and graduate students taking a course in advanced food analysis to DNA extraction, polymerase chain reaction (PCR), and DNA sequence analysis. Students provided their own fish sample, purchased from local grocery stores, and the class as a whole extracted DNA, which was then subjected to PCR, gel electrophoresis, and Sanger sequencing. Students retrieved their sequences and identified their fish using the NCBI BLAST nucleotide database. Slightly more than half of the samples yielded sequences identical or close to expected (based on the identification of the fish on the packaging); some other samples matched unanticipated fish or other organisms, due to an incomplete database, minor sequencing errors, or laboratory contamination (human and fungal sequences); 1 canned tuna sample identified as hake could represent food fraud.     

Losing the whole child? A national survey of primary education training provision for spiritual,moral, social and cultural development

International concerns about the performativity agenda in schools gives rise to concerns about the neglect of a holistic approach to teaching and learning. Whilst schools in England and Wales are legally obliged to promote the spiritual, moral, social and cultural (SMSC) development of children, little is known about how initial teacher training providers prepare trainees to do so. This project aims to address this gap in the literature. This paper details the findings of phase one of a National Survey which investigates trainers’ approaches to delivery and their views on the place of SMSC in primary schools. Findings suggest that trainers value SMSC, but time devoted to it is relatively low and policy changes are perceived to threaten SMSC’s security. The paper argues that it is vital that trainers empower trainees to understand the importance of holistic themes of their respective curricula, informed by critical engagement with theory, in order to avoid them being overshadowed by the performativity discourse.     

Virtual cerebral ventricular system: an MR-based three-dimensional computer model

The inherent spatial complexity of the human cerebral ventricular system, coupled with its deep position within the brain, poses a problem for conceptualizing its anatomy. Cadaveric dissection, while considered the gold standard of anatomical learning, may be inadequate for learning the anatomy of the cerebral ventricular system; even with intricate dissection, ventricular structures remain difficult to observe. Three-dimensional (3D) computer reconstruction of the ventricular system offers a solution to this problem. This study aims to create an accurate 3D computer reconstruction of the ventricular system with surrounding structures, including the brain and cerebellum, using commercially available 3D rendering software. Magnetic resonance imaging (MRI) scans of a male cadaver were segmented using both semiautomatic and manual tools. Segmentation involves separating voxels of different grayscale values to highlight specific neural structures. User controls enable adding or removing of structures, altering their opacity, and making cross-sectional slices through the model to highlight inner structures. Complex physiologic concepts, such as the flow of cerebrospinal fluid, are also shown using the 3D model of the ventricular system through a video animation. The model can be projected stereoscopically, to increase depth perception and to emphasize spatial relationships between anatomical structures. This model is suited for both self-directed learning and classroom teaching of the 3D anatomical structure and spatial orientation of the ventricles, their connections, and their relation to adjacent neural and skeletal structures.

Art,Design and Environment: A Programme for Teacher Education

This account of a programme for PGCE Art/Design students at University College Bretton Hall, Wakefield (UK) describes an attempt in initial teacher training to develop a course of study which links art, design, environment and education. It seeks to develop a range of perceptions of the built environment, including those of the artist, the critic and the designer. The ideas and methods of working developed on this programme support students’ work in schools. The paper explains the rationale and describes the intensive workshop programme, which includes streetwork, studio sessions and critique. It reports on students’ research and their work in schools. Issues include the place of built environment studies in the Art/Design curriculum, the use of the environment as an educational resource and learning methods and teaching strategies. It comments on the satisfactions and frustrations of developing such a programme in initial teacher education. It presents the work at Bretton Hall as a case study in a wider range of work currently being developed by students, tutors and teachers involved in other courses. They have come together through the ‘Site Specific Project’ to create a research network to support curriculum innovation and teachers’ professional development.     

Searching the Polish Medical Bibliography (Polska Bibliografia Lekarska) for trials

Background: The Polish Medical Bibliography (Polska Bibliografia Lekarska) contains 350 000 records dating from 1979. These records from the fields of medicine, nursing, dentistry, health care systems and preclinical sciences are from nearly 300 biomedical journals published in Poland. Methods: We systematically searched the Polish Medical Bibliography Part II (1996–2006) CD‐ROM (July 2006) using both English and Polish phrases for randomized trials, manually checked results and, for the trials identified in this way, sought these on medline and embase . Results: Systematic searching identified records of 680 randomized trials from all areas of health care. Nearly 40% of these were not found on either medline or embase . Conclusions: The Polish Medical Bibliography should be of interest to health care information specialists concerned with comprehensive searches for trials.
