Finite-element analysis was used to investigate the extent of bias in the ichnological fossil record attributable to body mass. Virtual tracks were simulated for four dinosaur taxa of different sizes (Struthiomimus, Tyrannosaurus, Brachiosaurus and Edmontosaurus), in a range of substrate conditions. Outlines of autopodia were generated based upon osteology and published soft-tissue reconstructi...

One of the most important challenges in planning and maintaining a digital repository is to predict the needed resources on a long term basis, especially storage size and processing power. The main problem emerges from the need to migrate the data at certain times to newer file types, which takes time and alters the needed storage space, potentially branching into several migration paths for in...

In conventional cold-storage organ preservation, the donor organ is flushed with University of Wisconsin (UW) solution at 0-4 degrees C. The initial flush is used to wash out blood from the microcirculation to allow optimal preservation with the UW solution. The component hydroxyethyl starch (HES) of UW is known to cause relatively high viscosity and a possible interaction with blood, i.e. incr...

OBJECTIVE To prospectively estimate the risk for earlier ovarian failure among women undergoing hysterectomy with ovarian preservation, as compared with women of similar age without hysterectomy. METHODS A prospective cohort study was conducted among women aged 30 to 47 years undergoing hysterectomy without bilateral oophorectomy (n=406) and women with intact uteri (n=465). Blood samples and ...

While it is well known that prolonged preservation of the intestinal graft causes severe mucosal damage after transplantation, little is known about the effect on neuromuscular function. The entire small intestine of adult hound dogs was flushed and preserved with cold lactated Ringer's solution and autotransplanted either immediately (n = 6) or after 24 hr (n = 6). Animals undergoing sham oper...

Liver transplantation is the successful treatment of end-stage liver disease; however, the ischaemia-reperfusion injury still jeopardizes early and long-term post-transplant outcomes. In fact, ischaemia-reperfusion is associated with increased morbidity and graft dysfunction, especially when suboptimal donors are utilized. Strategies to reduce the severity of ischaemia-reperfusion can be applie...

PURPOSE To evaluate the effect of donor and eye bank characteristics on graft rating and clinical outcomes after penetrating keratoplasty (PK) for keratoconus. METHODS This retrospective interventional case series included 252 keratoconic eyes which underwent PK. Donor data included age and sex, cause of death, death-to-preservation time, preservation-to-surgery time, epithelial and stromal s...

PURPOSE Surface disease is one of multiple variables affecting the quality of the postkeratoplasty donor cornea. Trauma to Bowman's layer before and during harvesting can denude the donor epithelium and result in epithelial defects in the donor following penetrating keratoplasty. Eye banks use death-to-preservation (DP) time intervals as long as 18 hours. This study evaluates the effects of hig...

The aim of the this study was to have a comparison between Zataria multiflora and Rosemarinus officinalis extractson quality of minced frozen silver carp preserved in cold storage temperature -18°C for six months. In this research, one control and three treatments of minced silver carp were prepared as Tr1 (+ Zataria), Tr2 (+Rosemary) and Tr3 (mixed with Rosemary and Zataria) all in normal pack...
