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)
The two-photon transition c ð3686Þ ! J=c is studied in a sample of 1:06 Â 10 8 c ð3686Þ decays collected by the BESIII detector. The branching fraction is measured to be ð3:1 AE 0:6ðstatÞ þ0:8 À1:0 ðsystÞÞ Â 10 À4 using J=c ! e þ e À and J=c ! þ À decays, and its upper limit is estimated to be 4:5 Â 10 À4 at the 90% confidence level. This work represents(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)
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), 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)
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)
