Investigations of syn‐sedimentary growth faults in the Last Chance delta (Ferron Sandstone, Utah, USA) show that fault‐bounded half‐grabens arrested high amounts of sand in the mouth bar and/or distributary channel areas. Fault‐controlled morphology causes changes in routing of the delta top to delta front drainage towards the long axis of half‐grabens. Faulting was spatially and temporally non‐systematic,...
The aim of this prospective, blinded, randomised controlled study was to compare novices' acquisition of the technical skills of ultrasound‐guided regional anaesthesia using either a meat phantom model or fresh‐frozen human cadavers. The primary outcome was the time taken to successfully perform an ultrasound‐guided sciatic nerve block on a cadaver; secondary outcomes were the cumulative score of...
The success of tissue regeneration to a certain extent lies on the mechanical and biological environments that the scaffold provides. The former has been addressed in terms of stiffness and strength in a range of tissue engineering scenarios. The latter is often related to fluid flow capacity of facilitating nutrient delivery, waste removal, and more importantly promoting tissue remodeling. This paper...
Osteoporotic fractures commonly occur in the elderly. Although current therapies are aimed at the prevention and treatment of osteoporotic fractures, studies examing the fracture healing process in osteoporotic bone are limited. We produced an osteoporotic rat model by ovariectomy (ovx) and maintained a low calcium diet (LCD) in order to evaluate the influence of osteoporosis on fracture healing....
