Differences in the mechanical properties of calcaneal artificial specimens, fresh frozen specimens, and embalmed specimens in experimental testing.
BACKGROUND Artificial calcanei, fresh-frozen cadaver specimens, and embalmed cadaver specimens were compared in experimental testing under biocompatible loading to clarify the biocompatibility of artificial calcaneal specimens for implant testing. METHODS Two different artificial calcaneal bone models (Sawbone, Pacific Research Laboratories, Vashon, WA, and Synbone, Synbone Inc., Davos, Switz...
متن کاملMycoplasma genitalium PCR: does freezing of specimens affect sensitivity?
Mycoplasma genitalium is an established cause of sexually transmitted infections. Studies of disease associations are often performed on archived specimens, but little is known about the effect of storage of specimens on the detection of M. genitalium. Genital swab and first-void urine specimens submitted for detection of M. genitalium were tested on the day of receipt. Remnants of positive ori...

متن کاملFabrication and microstructure control of nanoscale mechanical testing specimens via electron beam lithography and electroplating.
It has been demonstrated that the mechanical properties of materials change significantly when external dimensions are confined to the nanoscale. Currently, the dominant fabrication method for mechanical testing specimens with nanometer dimensions is by using focused ion beam (FIB) milling, which results in inevitable Ga(+) induced damage to the microstructure. Here, we report a FIB-less fabric...
متن کاملA Simple Apparatus for Freezing-Drying Histological Specimens
MANY of the conventional types of freezing-drying apparatus employ an oil or mercury diffusion-pump, backed by a rotary pump, to obtain the high vacua necessary to ensure that the water molecules which escape from the specimens have sufficient mean free path to enable them to reach the vapour trap. Clearly, the efficiency of the freezing-drying process might be greatly increased if the specimen...
