OBJECTIVE To investigate the effect of surface motion on the gene expression of proteoglycan 4 (PRG4), hyaluronan synthases (HAS1, HAS2) and on the hyaluronan (HA) and proteoglycan 4 (PRG4) release of chondrocytes from different zones of bovine articular cartilage. DESIGN Superficial zone, deep zone, full thickness, and superficial/deep 1:1 mixed(More)
In this paper a compact, yet sensitive gas detection system based on a modulated, tunable thulium-doped fiber laser in the 2 μm wavelength region is reported. The laser operating wavelength range centered at a wavelength of 1.995 μm has been selected to access the R(50) transition (ν1+2ν2+ν3) of CO2 based on its line strength and to achieve isolation from(More)
BACKGROUND Treatment of neuropathic pain remains a challenge. The current study investigated the therapeutic effect of intrathecal administration of NF-kappaB antisense oligodeoxynucleotides (ODNs) on mechanical allodynia and thermal hyperalgesia in a chronic constriction injury (CCI) model of rats. METHODS Lumbar intrathecal catheters were implanted in(More)
A spot weld & heating treatment tri-uses device based on modern mechanical-electric technique, was developed for dental spot weld, stainless steel orthodontic wire heating-reversion and Ni-Ti orthodontic wire heating-overload metamorphism. The device will be very helpful instrument in orthodontic clinic. The paper not only described the operating methods of(More)
A new laser scanning and measurement method was introduced for dental model three-dimensional form. A laser diode was used as scanning light source, two CCDs (they were fixed specially) received the diffused light reflected from the dental model. The dental model rotating-moved back and forth, and horizontal moved from one side to another along horizontal(More)
The effects of different rye chromosomes on Acph secretion of common wheat roots under P starvation conditions were studied by using a set of Chinese Spring-Imperial (CS-IMP) alien addition lines as materials. The Acph activity measurement results showed that P starvation is an induction factor for Acph gene expression; Different chromosomes of Imperial rye(More)
