Congratulations to all of those who have completed their RMS Diploma! Find out more about their projects
"The traditional light microscope has advanced our understanding of living systems in the last few centuries by its ability to reveal the microscopic world to us. Novel microscopy technologies allow us to monitor these living systems with ever increasing resolution in both spatial and temporal dimensions. In particular, the Selective Plane Illumination Microscopy (SPIM) promises to revolutionize research in developmental biology by capturing entire embryos with cellular resolution. My plan is to build a SPIM system on a limited budget without sacrificing its key benefits and thus make the technology available to a broad scientific community."
"It is intended within the course of this work, to determine how microscopy can be used to aid in the preparation of materials for microstructural analysis. Not only wil it look at the range of techniques to obtain the information from the fully prepared sample but will show how operators can use various aspects of microscopy to understand and develop sound technical procedures for the processes leading to that finished sample. Understanding these principles will allow metallographers to understand and employ best practice to prepare specimens correctly for later microstructural assessment."
"Necroptosis is a novel programed cell death pathway relevant for tumour cell responses to chemotherapeutic agents. In a recent study (Tenev et al., 2011), I developed a time-lapse video microscopy protocol using annexin V, PI and morphology to monitor necroptosis. In my diploma work I propose to extend these methodologies as a tool to analyse different types of cell death but with an emphasis on necroptosis. Once I have established a combination of dyes and fluorescent proteins that can distinguish several types of cell death I aim to utilise these to establish a screening platform for cell death."
"Neurite outgrowth as an important step during the nervous system development is still not completely understood. During my study I want to make use of a recently acquired high content screening microscope (Operetta, Perkin Elmer) to scan neuroblastma cells where different genes have been silenced using siRNA that are known to somehow influence the neurite outgrowth process. Afterwards I will use the Columbus software from Perkin Elmer to characterise the different phenotypes and to establish an analysis process that will then be of further use to many users."
"The proposed study will focus on the interactions between a variety of nanoparticles, synthesized within the host group with eukaryotic and bacterial cells. Furthermore, skills will be improved in a number of microscopy techniques, namely SEM imaging and EDS analysis, TEM imaging, EDS analysis and diffraction, and biological specimen preparation. The results will contribute to projects based on toxicology of nanoparticles to mammals and antibacterial properties on nanoparticles."
"Marek's disease virus (MDV) is an alphaherpesvirus which causes a lymphoproliferative disease in chickens. Inflection occurs by inhalation of infected dander and following a complex life cycle involving infection of B and T cells, the virus is shed from the feather follicle. Vaccination is available and prevents clinical disease however it does not prevent the shedding of virus. The feather follicle is important in the transmission of MDV as the feather follicle epithelium (FFE) is the only region where fully enveloped and infectious virus particles are assembled. This study aims to identify cell tropism and describe viral morphogenesis in the FFE using immunofluorescence and transmission electron microscopy."
"Polypropylene film is often coated with acrylic nano-particle formulations which contain migratory additives designed to modify the surface properties of the material. Whilst it is possible to quantify the levels using infra-red spectroscopy, this only provides a bulk assay.
It is hoped that a method to image the dried acrylic coating and map additive distributions on the dried surface can be developed to allow a study of the interaction of bulk levels and drying temperature on the migratory behaviour. This can then be correlated to physical and optical characteristics to optimise manufacturing conditions."
For myself it was a useful and rewarding experience. It has been a long time since I had carried out any detailed research and I did enjoy the investigative process. I had an aim but I wasn't actually sure where it would take me until I progressed through it. Applying the various techniques to investigate particular aspects which I understood or believed gave me further understanding of what is happening during materials preparation.
Now having this material I can use it for the training I do for Materials Preparation & Microscopy. I run these courses regularly for MetPrep and to have had the time to generate this additional data to highlight certain aspects was great. It gives those coming into the area of Materials Preparation & Materials Microscopy something to really latch on to & creates a better understanding.
