Reconstructive surgery of the head and neck is a demanding field. The specific anatomical complexity of the region, and its almost inevitable exposure to the public, demand for highly refined and careful reconstructive procedures. In fact, in the last decades, the trend in reconstructive surgery, as for the general medical field, is to put the standard of care in an extremely high level and thi...

3d imagination of human's organs has become feasible by digital image processing techniques and algorithms via ct or mri images in recent years. in this study, a new method for reverse engineering and biomodelling of hard tissues by catia cloud points' concept has been considered. comparing with the current softwares (e.g. biobuild or mimics) has shown the new method's easiness of implementing ...

Rapid prototyping (RP), or stereolithography, is a new clinical application area, which is used to obtain accurate three-dimensional physical replicas of complex anatomical structures. The aim of this study was to create tangible hard copies of the ethmoidal labyrinth air cells (ELACs) with stereolithographic biomodelling. The visible human dataset (VHD) was used as the input imaging data. The ...

The intramolecular model (Ehrenfeucht et al, 2001) for gene assembly in ciliates considers three operations, ld, hi, and dlad that can assemble any micronuclear gene pattern through folding and recombination: the molecule is folded so that two occurrences of a pointer (short nucleotide sequence) get aligned and then the sequence is rearranged through recombination of pointers. In general, the s...

Claudins are family of proteins of tight junctions establishing the paracellular barrier that controls the flow of molecules in the intercellular space between the cells of an epithelium. Claudin 1 protein plays significant role in Enteropathogenic Escherichia coli infection which is an important agent of infectious diarrhea, especially in pediatric populations. The crystal structure of Claudin...

BACKGROUND The facial fracture biomodel is a three-dimensional physical prototype of an actual facial fracture. The biomodel can be used as a novel teaching tool to facilitate technical skills training in fracture reduction and fixation, but more importantly, can help develop diagnostic and management competence. OBJECTIVE To introduce the 'facial fracture biomodel' as a teaching aid, and to ...

The paper explores a biomodelling method comprising of several visual and virtual reality methods to assess different surgical procedures using the computer. A computer tomography (CT) medical scan of a patient was obtained and was converted into a three dimensional virtual biomodel. This mandible biomodel was then subjected to graphical post-processing to split it into two portions mimicking a...
