OBJECTIVES Right ventricular heart rupture is a devastating complication associated with negative pressure wound therapy (NPWT) in cardiac surgery. The use of a rigid barrier has been suggested to offer protection against this lethal complication, by preventing the heart from being drawn up and damaged by the sharp edges of the sternum. The aim of the present study was to investigate whether a ...

purpose : to report a rare case of large vascularized astrocytoma on optic disc. case report : a 12-year-old boy with history of decreased vision in the left eye since 5-6 months ago was referred to the ocular oncology service at rassoul akram hospital with provisional diagnosis of retinoblastoma. on examination, visual acuity was counting fingers at 50 cm, and a 3+ relative afferent pupillary ...

Rajiform locomotion in fishes is dominated by distinctive undulations of expanded pectoral fins. Unlike other fishes, which typically interact with the fluid environment via multiple fins, undulating rays modulate a single control surface, the pectoral disc, to perform pelagic locomotion, maneuvering and other behaviors. Complex deformations of the broad, flexible pectoral fins occur as the und...

BACKGROUND The use of lumbar supports has been associated with decreased reports of low back pain during driving exposures. However, there has been limited work investigating whether lumbar supports actually change spine and pelvic postures at the level of the vertebrae. PURPOSE To investigate the effectiveness of a lumbar support in changing radiological measures of lumbar spine and pelvic p...

The emission of the airborne particles from epoxy resin test sticks with different CNT loadings and two commercial products were characterized while sanding with three grit sizes and three disc sander speeds. The total number concentrations, respirable mass concentrations, and particle size number/mass distributions of the emitted particles were measured using a condensation particle counter, a...

17 Recent studies have shown that chromogenic cephalosporin tests are inferior to disc zone edge tests in 18 detecting penicillinase in Staphylococcus aureus isolates resulting in a change to CLSI and EUCAST 19 guidelines in 2012. We sought to confirm these findings using Australian isolates and compare the 20 performance of the CLSI and EUCAST methods which use different disc strengths, penici...

BACKGROUND The effect of the menopause and HRT on the intervertebral discs has not been investigated. METHODS One hundred women were recruited, comprising of 44 post-menopausal women on HRT, 33 untreated post-menopausal women and 23 pre-menopausal women. The height of the intervertebral discs between the 12th thoracic vertebra and the 3rd lumbar vertebra was measured by utilizing the bone den...
