Reported mechanical properties of orbital connective tissue and fat have been too sparse to model strain-stress relationships underlying biomechanical interactions in strabismus. We performed rheological tests to develop a multi-mode upper convected Maxwell (UCM) model of these tissues under shear loading. From 20 fresh bovine orbits, 30 samples of connective tissue were taken from rectus pulle...

Twenty six children with overlapping features of more than one connective tissue disorder are reported. The median age of onset was 9.5 years and median duration of follow up 7.5 years. Common presenting symptoms included arthritis, tenosynovitis. Raynaud's phenomenon, myositis, and rashes. At follow up 14 patients had developed sclerodermatous skin changes, but significant systemic involvement...

The traditional way to study the properties of visual neurons is to measure their responses to visually presented stimuli. A second way to understand visual neurons is to characterize their responses in terms of activity elsewhere in the brain. Understanding the relationships between responses in distinct locations in the visual system is essential to clarify this network of cortical signaling ...

When two nominal constituents are in a relation of dependency in the Bantu languages, the syntactically dependent constituent is usually introduced by a relator. In Bantu studies this relator is called connective (also associative, genitive or connexive) element (or pronoun, clitic, prefix, marker or particle). The order is HEAD (R1) RELATOR (REL) DEPENDENT (R2). R1 and R2 are short for first a...

A method to extend the Hough transform (HT) to detect connectivity by ordered accumulation is reported. The method is applied to the dynamic combinatorial HT [6]. A focus of attention mechanism is also reported. Our connective HT with focus of attention reduces the computational complexity of the DCHT and increases the S/N ratio of the peak in its accumulator. It may be regarded as a principled...

A polypeptide which induces hypermetabolism in normal synovial fibroblasts in tissue culture is described. The metabolic changes induced included a marked increase in hyaluronate formation, lactate formation and glucose uptake; formation of soluble and fibrous collagen was depressed. An assay method is presented which permits quantitative comparisons of samples for connective tissue activating ...

14 C-gldcommine and '5S04-labeled glycosaminoglycan (GAG) synthesis, 2) responsiveness to autacdid mediators, and 3) perfarmance following maximal stimulation. Under basal conditions, SF synthesized and secreted 2-3 times more radioactive hyaluronic acid than the NF (P < 0.001); molecular volume by gel chromatography was similar and suggested a high molecular weight ptoduct. SF were essentially...

Extraocular muscle pulleys, now well known to be kinematically significant extraocular structures, have been noted in passing and described in fragments several times over the past two centuries. They were late to be fully appreciated because biomechanical modeling of the orbit was not available to derive their kinematic consequences, and because pulleys are distributed condensations of collage...

Background and aims. Connective tissue grafts with and without periosteum is used in regenerative treatments of bone and has demonstrated successful outcomes in previous investigations. The aim of present study was to evaluate the effectiveness of connective tissue graft with and without periosteum in regeneration of intrabony defects. Materials and methods. In this single-blind randomized spli...

A comparative study of spinal connective tissue and its structural arrangement was carried out using tissue preserved in epoxy resin plastinated slices and paraffin embedded sections. The 2.5mm horizontal plastinated slices provide a more complete overview of connective tissue arrangement in the spine, including fibre arrangement, bony attachment sites and, continuity with neighbouring structur...
