BACKGROUND Classical crush has a lower rate of final kissing balloon inflation (FKBI) immediately after percutaneous coronary intervention (PCI). The double kissing (DK) crush technique has the potential to increase the FKBI rate, and no prospective studies on the comparison of classical with DK crush techniques have been reported. MATERIALS AND METHODS Three hundred and eleven patients with ...
An experimental crush injury to the sciatic nerve, with a crush force of 49.2 N (pressure p=1.98x10(8) Pa), was inflicted in 30 male rats (Wistar). A control group (sham), with the same number of rats, was also operated upon exactly as the experimental group but without the crush injury. We tested the sensory and motor recovery of the sciatic nerve with Hargreaves method, using an apparatus fro...
Motorcycle helmets reduce the frequency and severity of head and brain injuries by attenuating head acceleration and distributing the impact force. This is achieved primarily through permanent crushing of the interior energy absorbing liner. Our goal is to characterize the relationship between residual helmet damage and impact energy. Working toward this goal, the current study measures the cha...
مقدمه: سندرم carpal tunnel (cts) به تحت فشار قرار گرفتن عصب median در داخل تونل carpal گفته می شود. بروز سندرم double crush در شرایطی است که به شاخه های عصبی که در تشکیل عصب median دخالت دارند، در ناحیه ی گردن یا نواحی بالاتر از مچ دست فشار وارد شود و یا این شاخه ها دچار التهاب شوند. در این صورت، حساسیت عصب median که در مچ دست قرار دارد، به فشار بیشتر می شود. هدف از این مطالعه، تعیین میزان شیوع...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
BACKGROUND During atrial flutter, double potentials may be recorded at specific sites in the atria. It has been suggested that double potentials represent sequential activations at the center of the reentrant circuit. An alternative hypothesis is that double potentials represent electrical activity in an area of slow conduction. Understanding their mechanism is important because double potentia...
In this paper, the energy absorption features of tri-layer explosive-welded deep-drawn cups subjected to quasi-static axial compressive loading are investigated numerically and experimentally. To produce the cups, tri-layer blanks composed of aluminum and stainless steel alloys were fabricated by an explosive-welding process and formed by a deep drawing setup. The quasi-static tests were carrie...
Abstract To this day, the trial of Pol Pot in July 1997 Anlong Veng remains an underexplored topic, possibly because it is seen as a parody justice organised by rival Khmer Rouge faction. Images event show old and fragile man who has to be supported guards meeting hall. Drawing on anthropologist Ashley Thompson’s study ‘substitute body king’, paper examines corporeal strategies at play display ...
Extensive muscle crush injury culminating in a crush syndrome or traumatic rhabdomyolysis is often lethal unless treated actively on war footing. The causes of death in crush syndrome include hypovolemic shock, hyperkalemia, hypocalcemia, metabolic acidosis, acute myoglobinuric renal failure and the acute muscle – crush compartment syndrome. The literature is divided on the treatment, while som...
