Microarray analysis of gene expression was performed in the healing femur fractures of 13-week-old male rats during the inflammatory stageof repair, at 3 days post-fracture, and the endochondral bone formation stage of repair, at 11 days post-fracture. Multiple replicate pairs of fracturetissues paired with unfractured tissues, and unfractured control bones that had the stabilizing K-wi...

It is still debate of the relationship between the dietary protein consumption and risk of fracture. We searched Medline and Embase to assess the effects of dietary protein consumption on risk of fracture. Twelve prospective cohort studies with 407,104 participants were included, higher total protein consumption may be decrease 11% risk of hip fractures, with adj. RR of 0.89 (0.82, 0.97), no si...

The role that plastic-frictional energy dissipation in the fracture process zone plays in the workof-fracture method for measuring the fracture energy of concrete or other quasibrittle materials is analyzed, and a possible improvement of this method is proposed. It is shown that by measuring the unloading compliance at a sufficient number of states on the post-peak descending load-deflection cu...

During crack growth of real materials, the total energy released can be partitioned into elastic and dissipative terms. By analyzing material models with mechanisms for dissipating energy and tracking all energy terms during crack growth, it is proposed that computer simulations of fracture can model crack growth by a total energy balance condition. One approach for developing fracture simulati...

BACKGROUND Type-1 and type-2 diabetes mellitus (DM) are associated with an increased fracture risk and possibly an increased risk of death following a fracture. AIM To investigate the association between diabetes-related drugs and mortality following a fracture. METHODS A nested case-control study was conducted. Cases were patients with DM who died following a fracture; controls were DM pat...

The association between mental disorders (MDs) and iatrogenic complications after hip fracture surgery has been poorly studied. Among iatrogenic complications, nosocomial infections (NIs) are a major factor in hip fracture surgery. The aim of this paper was to determine whether patients with a MD and a hip fracture develop more NIs after hip surgery than patients with no MD. We studied 912 pati...
