We exposed human macrophages isolated from the peripheral blood of healthy donors to metal and bone-cement particles from 0.2 to 10 microm in size. Zymography showed that macrophages exposed to titanium alloy and polymethylmethacrylate (PMMA) particles released a 92- and 72-kDa gelatinase in a dose- and time-dependent manner. Western immunoblotting(More)
BACKGROUND After open wedge high tibial osteotomy (OWHTO), the proximal fragment resembles the anatomy of the proximal tibia that is aligned in the anterior-posterior direction and the distal fragment resembles the anatomy of the mid shaft that is aligned in the proximal-distal direction. In addition, the medial portion of the proximal fragment becomes(More)
PURPOSE We attempted to determine the degree of rotation of the femoral component to achieve an ideal rectangular flexion gap with minimal medial collateral ligament (MCL) release using a modified measured technique. MATERIALS AND METHODS Group I consisted of 60 osteoarthritis patients (72 cases) who underwent total knee arthroplasty (TKA) with minimal(More)
The decays ψ'→γπ(0), γη and γη' are studied using data collected with the BESIII detector at the BEPCII e(+)e(-) collider. The processes ψ'→γπ(0) and ψ'→γη are observed for the first time with signal significances of 4.6σ and 4.3σ, respectively. The branching fractions are determined to be B(ψ'→γπ(0))=(1.58±0.40±0.13)×10(-6),(More)
The effects of calcium hopantenate (HOPA), a GABA agonist, on the release of thyrotropin-releasing hormone (TRH) from the rat adrenal gland were studied in vitro. The adrenal glands were incubated in medium 199 with 1.0 mg/ml of bacitracin (pH 7.4) (medium) for 20 min. The amount of TRH release into the medium was measured by radioimmunoassay. The TRH(More)
Effects of histamine and related compounds on the release of immunoreactive thyrotropin-releasing hormone (ir-TRH) from the rat stomach in vitro were studied. The rat stomach was incubated in medium 199 with 1.0 mg/ml of bacitracin and 100 micrograms/ml of ascorbic acid (pH 7.4) for 20 min. The amount of TRH release into the medium was measured by(More)
The effects of calcium hopantenate (HOPA) on plasma beta-endorphin-like immunoreactivity (beta-En-LI) levels in rats have been studied. HOPA (1.5 g/kg) was injected ip, and the animals were serially decapitated. The plasma beta-En-LI levels were measured by radioimmunoassay. Effects of HOPA on beta-En-LI release from the anterior pituitary were also(More)
