Signal transduction pathways controlling the induction of bone formation by macroporous biomimetic matricesKlar, Roland Manfred 27 March 2015 (has links)
In spite of vigorous research efforts to date the induction of bone formation by
macroporous coral-derived constructs when implanted heterotopically in the rectus
abdominis muscle of the non-human primate Chacma baboon Papio ursinus has not yet
been resolved and needs to be assigned. More importantly, the apparent redundancy of
molecular signals singly initiating the induction of bone formation in primate species and
the heterotopic induction of endochondral bone formation by the mammalian recombinant
human transforming growth factor –β3 (rhTGF-β3) isoform have not yet been assigned and
need to be mechanistically resolved. Using the rectus abdominis muscle of Papio ursinus
the study sought to molecularly determine how coral-derived macroporous constructs and
doses of the hTGF-β3 isoform initiate the induction of bone formation. To elucidate the
function of osteoclastogenesis and Ca2+, biomimetic coral-derived 7%
hydroxyapatite/calcium carbonate (7% HA/CC) devices were supplemented either with
240 μg zoledronate bisphosphonate, an osteoclast binding antagonist, or 500 μg of the
calcium channel blocker verapamil hydrochloride. Additionally but in separate coralderived
bioreactors, 125 μg rhTGF-β3 and/or 125 μg hNoggin were added to answer the
question of how TGF-β3 induces bone formation. All devices were then subsequently
implanted within heterotopic sites of the rectus abdominis muscle of 6 Papio ursinus and
left in vivo for 15, 60 and 90 days. Harvested specimens were subjected to
histomorphometrical and quantitative reverse transcription polymerase chain reaction
(qRT-PCR) analysis. Collagen Type IV expression supported by extensive vascularisation
was detected and observed respectively in all implants after 15 days in vivo. Importantly
the zoledronate treated specimens possessed delayed tissue patterning and morphogenesis,

Analysis of alterations in matrix quality at nanoscale in metabolic bone diseases using synchrotron X-ray diffractionKarunaratne, Malintha P. Angelo January 2013 (has links)
Bone diseases such as osteoporosis and rickets cause significant reduction in bone quantity and quality, leading to mechanical abnormalities. While the reduction of bone quantity can be assessed using clinical tools like DXA and pQCT, there is little quantitative knowledge of how altered bone quality in diseased bone increases fracture risk. There is a clear need to develop high-resolution diagnostic techniques to close the gap between onset of fracture relevant changes and diagnosis. Here, a functional imaging technique (in situ synchrotron X-ray imaging with micromechanics) was developed to measure alterations in fibrillar deformation mechanisms in rickets, glucocorticoid-induced osteoporosis (GIOP), and premature ageing. During applied loading, percentage shifts in Bragg peak positions arising from the meridional collagen stagger, measured from the small angle X-ray scattering (SAXS) patterns, give fibrillar level strain as a function of applied stress in real time. To link nanostructural changes to altered fracture risk and deformability, well defined animal (mouse) models created via N-ethylnitrosurea mutagenesis were used. The fibril modulus, maximum fibril strain and fibril-to-tissue strain ratio were determined, complemented by quantitative backscattered scanning electron microscopy and microcomputed tomography to measure microscale mineralisation. A significant reduction of fibril modulus and enhancement of maximum fibril strain was found in rickets and GIOP mice. A significantly larger fibril strain/tissue strain ratio was found in GIOP mice compared to wild-type mice, indicative of a lowered mechanical competence at the bone matrix level. The effects of altered in vivo muscular force distributions on the skeletal system in rickets were measured using position resolved scanning SAXS. Increase of mineral nanoplatelet alignment is observed in wild-type mice near zones of large in-vivo muscle force but not in rachitic mice. These results demonstrate the ability of synchrotron-based in situ X-ray nanomechanical imaging to identify functional alterations in nanoscale bone quality in metabolic bone diseases.

Scaphoid variation and an anatomical basis for variable carpal mechanicsFogg, Quentin A. January 2004 (has links)
The morphology and function of the wrist is poorly understood. Improved understanding of carpal anatomy may facilitate improved understanding of carpal mechanics and may enhance the clinical management of wrist dysfunction. Many detailed investigations of wrist structure have been reported, many of which have focussed on the scaphoid and its ligamentous supports. The results of these studies are not readily collated to provide an accurate description of the scaphoid and its supports. This study attempted to provide a detailed description of the anatomy of the scaphoid and its supporting structures. A detailed nomenclature was proposed to facilitate accurate description of the scaphoid and related structures. Gross observation enabled separation of the sample population of scaphoids into two groups. Morphometric analyses were used to determine any significant differences between the groups (type one and type two). The histological sections were then used to facilitate accurate gross identification of ligaments and computed tomographs were used to investigate the in situ variation of scaphoid orientation. The investigations suggest that two distinct populations of scaphoid existed within the sample population. The scaphoids varied in bone morphology, arrangement and degree of ligamentous support and position relative to the capitate. Articular facet shape and size differed between scaphoid types. The orientation and number of ligaments supporting the scaphoid were suggestive of variable scaphoid motion. The variation in ligamentous patterns was supported by histological investigation. Computed tomographs through the longitudinal axis of the scaphoid suggested a variable position of the scaphoid relative to the capitate. The variation of these structures was discussed in relation to the kinematic findings of others. A theoretical model of variable scaphoid function was proposed based on the anatomical findings. The data presented and the reviewed kinematic data may be extrapolated to suggest two models of scaphoid motion. The scaphoids may be divided into rotating/translating scaphoids and flexing/extending scaphoids. This must be confirmed by a combined anatomical and mechanical study. The clinical implications of different scaphoid structure and function may be profound. The ability to identify such differences in situ may facilitate varied clinical management for the various types of wrist suggested. / Thesis (Ph.D.)--Department of Anatomical Sciences, 2004.
