An understanding of human embryology is essential for students to better understand the subjects of human anatomy and physiology. However, human embryology is a challenging subject for many, since they must learn how anatomic structures and physiological processes develop over a period of time. Embryology texts typically use static, two-dimensional images to illustrate the dynamic three-dimensional developmental processes, making it difficult for a student to understand spatial relationships and sequential steps. To help students conceptualize these series of complex dynamic developmental events that occur over time, two of the authors and a graphic artist developed six web-based cardiovascular embryology animations and housed them on an Indiana University website. This research study examines knowledge gains and user satisfaction of students, faculty, and laypeople around the world who accessed these six website animations. Data collection spanned 6 yr, and pretest/posttest assessments (ranging from 4 to 7 multiple-choice questions each) were used to determine immediate knowledge gains of cardiovascular embryology. The total number of completed pretest/posttest assessments ranged from 555 to 1,449 per animation. The number of correct posttest scores was significantly improved over matched pretest scores (confidence interval range 1.3–3.2, depending on the animation, P < 0.001), suggesting the animations are useful for embryology learning (at least in the short term). Demographic and user satisfaction information was gathered with an anonymous survey at the end of each animation. Survey data from all animations indicated participants found the animations easy to use and very effective for their learning. This research highlights the positive impacts of web-based animations on learning complicated events of cardiovascular embryology.

Our natural world is multi-dimensional in which the spatial coordinates of an object are, for a given moment of time, fixed relative to each other. These fixed points change, either very rapidly as in the case of most living material, or very slowly as with metals and rocks. The rates of change are influenced by environmental factors such as temperature, pressure, humidity and electromagnetic radiation.Sight together with the coupled neuro-physiological processes is the most powerful of our noninvasive senses for detecting, imaging and analysing what is happening in our environment. Our memory serves us reasonably well as a short term archiving mechanism. The images we see arise as a consequence of selective scattering and absorption of a small portion of the electromagnetic spectrum as it interacts with the specimen. We quickly learn how to interpret the information-rich images we are presented with in our daily life; we can perceive motion, minute changes in patterns and the three dimensional location of objects.

This report describes preliminary research and experiments towards the collaborative viewing and manipulation of three-dimensional computer models of human anatomy and physiology on low-end computers using limited bandwidth. A proposed system is described using a set of recommended requirements. Experiments that were conducted to explore the feasibility of some aspects of the proposed system are also described. The resulting experimental system was implemented on networked 100 MHz and 90 MHz Pentium-based computers enhanced with 3-D graphics accelerators. Geometry for the anatomy models were stored in Virtual Reality Modeling Language (VRML) version 1.0 files, which could be accessed remotely over the Internet. Some models were later implemented as VRML 2.0 files, which enabled the storage of simple physiological behaviors with the geometry. The use of VRML, the de facto standard file format for 3-D modeling on the Web, in a medical collaboration system would help make such systems, which have been typically implemented on special-purpose hardware with proprietary anatomical and physiological models, much more accessible.

AbstractUnderstanding spatial gene expression and regulation is key to uncovering developmental and physiological processes, during homeostasis and disease. Numerous techniques exist to gain gene expression and regulation information, but very few utilise intuitive true-to-life three-dimensional representations to analyze and visualize results. Here we combined spatial transcriptomics with 3D modelling to represent and interrogate, transcriptome-wide, three-dimensional gene expression and location in the mouse adult heart. Our study has unveiled specific subsets of genes that display complex spatial expression in organ sub-compartments. Also, we created a web-based user interface for spatial transcriptome analysis and visualization. The application may be accessed from http://3d-cardiomics.erc.monash.edu/.

Abstract Three-dimensional (3-D) mathematical models of water currents, transport, mixing, reaction kinetic, and interactions with bottom and air have been used in Finland regularly since 1982 and applied to about 40 cases in large lakes, inland seas and their coastal waters. In each case, model validity has been carefully tested with available flow velocity measurements, tracer studies and water quality observations. For operational use, i.e., for spill combatting and sea rescue, the models need fast response, proven validity and illustrative visualization. In 1987-90, validated models were implemented for operational use at five sea areas along the Finnish coast. Further validation was obtained in model applications from nine documented or arranged cases and from seven emergency situations. Sensitivity tests supplement short-term validation. In the Bothnian Sea, it was nescessary to start the calculation of water currents three days prior to the start of the experiment to reduce initial inaccuracies and to make the coastal transport estimates meaningful.
