Vlogging campus community stories

Student voice is a powerful signifier for sharing the institutional habitus of a campus. With our new Caboolture Campus Community Stories initiative, we place students in the role of vloggers (video bloggers) to capture and distribute the stories, activities and events of the QUT environment. These stories present visual narratives through the eyes of students about university experience, academic practice and the transition from High School to first year, all intending to promote a sense of community and belonging, normalize academic practices and build an inclusive institutional habitus. These stories are placed on community websites and digital signage around campus as resources for first year students and prospective students.

Stimuli-responsive colorimetric and NIR fluorescence combination probe for selective reporting of cellular hydrogen peroxide

Hydrogen peroxide (H2O2) is a key reactive oxygen species and a messenger in cellular signal transduction apart from playing a vital role in many biological processes in living organisms. In this article, we present phenyl boronic acid-functionalized quinone-cyanine (QCy-BA) in combination with AT-rich DNA (exogenous or endogenous cellular DNA), i.e., QCy-BA subset of DNA as a stimuli-responsive NIR fluorescence probe for measuring in vitro levels of H2O2. In response to cellular H2O2 stimulus, QCy-BA converts into QCy-DT, a one-donor-two-acceptor (D2A) system that exhibits switch-on NIR fluorescence upon binding to the DNA minor groove. Fluorescence studies on the combination probe QCy-BA subset of DNA showed strong NIR fluorescence selectively in the presence of H2O2. Furthermore, glucose oxidase (GOx) assay confirmed the high efficiency of the combination probe QCy-BA subset of DNA for probing H2O2 generated in situ through GOx-mediated glucose oxidation. Quantitative analysis through fluorescence plate reader, flow cytometry and live imaging approaches showed that QCy-BA is a promising probe to detect the normal as well as elevated levels of H2O2 produced by EGF/Nox pathways and post-genotoxic stress in both primary and senescent cells. Overall, QCy-BA, in combination with exogenous or cellular DNA, is a versatile probe to quantify and image H2O2 in normal and disease-associated cells.

Hamburg, Germany, 1725 (Raster Image)

This layer is a georeferenced raster image of the historic paper map entitled: Hamburgum celeberrima libera imperii et Hanseatica civitas ac opulentissimum emporium circa ostium Albis ad mare septentr = Hamburg eine weltberühmte Freye Reichs und Hansee- auch Reiche u. Volkreiche Handels statt an der Elb nicht Weit von der Nord See, Heraus gegeben u. erlegt von Matthaeus Seutter Kupfferstl. Augsp. It was published by Matthaeus Seutter in [1725]. Scale [ca. 1:7,532]. Map in Latin and German. Covers Hamburg, Germany. The image inside the map neatline is georeferenced to the surface of the earth and fit to the WGS84 UTM Zone 32N coordinate system. All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as roads, drainage, built-up areas and selected buildings, fortification, ground cover, and more. Relief is shown by hachures and pictorially. Includes index and inset view: Hamburg. This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection as part of the Imaging the Urban Environment project. Maps selected for this project represent major urban areas and cities of the world, at various time periods. These maps typically portray both natural and manmade features at a large scale. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.
