Background and Objective: Umbilical Cord blood (UCB) hematopoietic stem cell (HSC) transplantation is a therapeutic approach for the treatment of malignant and non-malignant hematologic disorders due to ease of collection, lack of risk for donors and lower levels of infection. Moreover, it is considered a good alternative for bone marrow HSC transplantation. The main limitation of their use is ...

During every Australian summer fires are common in the south-eastern region of the continent. The combined forces of climate, topography and vegetation make Victoria in particular, one of the most fire prone regions on earth (DSE 2003). Throughout its history, Victoria has seen a number of devastating bushfires, including Black Friday 1939, Ash Wednesday 1983, and more recently in the northeast...

We adopt a spectral-element method (SEM) to perform numerical simulations of the complex wavefield generated by the 6 April 2009 Mw 6.3 L’Aquila earthquake in central Italy. The mainshock is represented by a finite-fault solution obtained by inverting strong-motion and Global Positioning System data, testing both 1D and 3D wavespeed models for central Italy. Surface topography, attenuation, and...

Current concepts of cell migration were established in regular two-dimensional (2D) cell culture, but the roles of topography are poorly understood for cells migrating in an oriented 3D fibrillar extracellular matrix (ECM). We use a novel micropatterning technique termed microphotopatterning (microPP) to identify functions for 1D fibrillar patterns in 3D cell migration. In striking contrast to ...

INTRODUCTION: There has been an increasing interest in the applications of three-dimensional (3D) printing in plastic surgery.1,2 A physical 3D model provides visualization of complex defects that supersede digital imaging and can be used as a template for preoperative planning and surgical education.3,4With the advent of affordable quality and reliable printers, office-based 3D printing has be...

Background Scoliosis patients typically undergo numerous spinal radiographs and exposed to relatively high doses of ionizing radiation. This has raised concern regarding the effects of this repeated exposure. Additionally assessment of spinal deformities using surface topography of the back is currently considered essential. Digital Photogrammetry can contribute in non-invasive measurements of ...

In this paper two concepts for modelling 3D topography are introduced. The first concept is a very pragmatic approach of 3D modelling, trying to model as much as possible in (less complicated) 2.5D and use 3D modelling only in exceptional cases. The idea is to use a constrained TIN in 2.5D and place 3D TENs on top or below this surface. As both data structures use the same simplexes (nodes, edg...

Multispectral three-dimensional (3D) imaging provides spatial information for biological structures that cannot be measured by traditional methods. This work presents a method of tracking 3D biological structures to quantify changes over time using graph theory. Cell-graphs were generated based on the pairwise distances, in 3D-Euclidean space, between nuclei during collagen I gel compaction. Fr...
