Journey to the centre of the cell: Virtual reality immersion into scientific data.

Visualization of scientific data is crucial not only for scientific discovery but also to communicate science and medicine to both experts and a general audience. Until recently, we have been limited to visualizing the three-dimensional (3D) world of biology in 2 dimensions. Renderings of 3D cells are still traditionally displayed using two-dimensional (2D) media, such as on a computer screen or paper. However, the advent of consumer grade virtual reality (VR) headsets such as Oculus Rift and HTC Vive means it is now possible to visualize and interact with scientific data in a 3D virtual world. In addition, new microscopic methods provide an unprecedented opportunity to obtain new 3D data sets. In this perspective article, we highlight how we have used cutting edge imaging techniques to build a 3D virtual model of a cell from serial block-face scanning electron microscope (SBEM) imaging data. This model allows scientists, students and members of the public to explore and interact with a "real" cell. Early testing of this immersive environment indicates a significant improvement in students' understanding of cellular processes and points to a new future of learning and public engagement. In addition, we speculate that VR can become a new tool for researchers studying cellular architecture and processes by populating VR models with molecular data.

Exploring Team-Based Teaching of Basic Sciences and Clinical Practice: Experiences of Pharmacy Students at a Malaysian Pharmacy School.

Interdisciplinary learning combining foundational science concepts and clinical practice applications is important in many healthcare-related programmes, including pharmacy. The coherent, structured interdisciplinary curricula designed by specialists may not always be perceived as integrated by students. Team teaching, an education approach where two or more instructors share teaching responsibilities within a classroom setting, may help eliminate this perception. This study aims to explore whether team teaching can improve Asian students' experience of learning in an undergraduate pharmacy programme in Malaysia. A single 2-h interactive lecture session was delivered using a team-based approach to year 4 undergraduate pharmacy students enrolled at the School of Pharmacy, Monash University Malaysia, from 2015 to 2017. All students who attended the team-based teaching lectures were provided with an anonymous link, which requested responses on their views towards team-based teaching. Fifty out of 104 participants from three different cohorts responded to the survey of this study. Over 75% of students reported that they learnt better with the team teaching approach compared to traditional lectures delivered by one lecturer and that the team teaching approach was superior to private study. About 60% of the participants agreed that the team-based teaching approach helped develop their information-synthesising and problem-solving skills. This study provides evidence for using team teaching for design and delivery in an Asian context. The approach was well received by the participants.

In vivo analysis of growth hormone receptor signaling domains and their associated transcripts.

The growth hormone receptor (GHR) is a critical regulator of postnatal growth and metabolism. However, the GHR signaling domains and pathways that regulate these processes in vivo are not defined. We report the first knock-in mouse models with deletions of specific domains of the receptor that are required for its in vivo actions. Mice expressing truncations at residue m569 (plus Y539/545-F) and at residue m391 displayed a progressive impairment of postnatal growth with receptor truncation. Moreover, after 4 months of age, marked male obesity was observed in both mutant 569 and mutant 391 and was associated with hyperglycemia. Both mutants activated hepatic JAK2 and ERK2, whereas STAT5 phosphorylation was substantially decreased for mutant 569 and absent from mutant 391, correlating with loss of IGF-1 expression and reduction in growth. Microarray analysis of these and GHR(-/-) mice demonstrated that particular signaling domains are responsible for the regulation of different target genes and revealed novel actions of growth hormone. These mice represent the first step in delineating the domains of the GHR regulating body growth and composition and the transcripts associated with these domains.

A Simulated Learning Environment for Teaching Medicine Dispensing Skills.

OBJECTIVE: To develop an authentic simulation of the professional practice dispensary context for students to develop their dispensing skills in a risk-free environment. DESIGN: A development team used an Agile software development method to create MyDispense, a web-based simulation. Modeled on virtual learning environments elements, the software employed widely available standards-based technologies to create a virtual community pharmacy environment. Assessment. First-year pharmacy students who used the software in their tutorials, were, at the end of the second semester, surveyed on their prior dispensing experience and their perceptions of MyDispense as a tool to learn dispensing skills. CONCLUSION: The dispensary simulation is an effective tool for helping students develop dispensing competency and knowledge in a safe environment.

Molecular phylogeny of edge hill virus supports its position in the yellow Fever virus group and identifies a new genetic variant.

Edge Hill virus (EHV) is a mosquito-borne flavivirus isolated throughout Australia during mosquito surveillance programs. While not posing an immediate threat to the human population, EHV is a taxonomically interesting flavivirus since it remains the only member of the yellow fever virus (YFV) sub-group to be detected within Australia. Here we present both an antigenic and genetic investigation of collected isolates, and confirm taxonomic classification of the virus within the YFV-group. Isolates were not clustered based on geographical origin or time of isolation, suggesting that minimal genetic evolution of EHV has occurred over geographic distance or time within the EHV cluster. However, two isolates showed significant differences in antigenic reactivity patterns, and had a much larger divergence from the EHV prototype (19% nucleotide and 6% amino acid divergence), indicating a distinct subtype or variant within the EHV subgroup.
