Pitavastatin approved for treatment of primary hypercholesterolemia and combined dyslipidemia
Pitavastatin was first developed in Japan and is expanding the regions in which it is clinically available. A considerable number of clinical studies have been conducted and published to date on the usefulness of pitavastatin for patients with primary hypercholesterolemia or combined dyslipidemia. Pitavastatin demonstrates potent low-density lipoprotein cholesterol reduction at low doses of 1–4 mg/day. It also affects the regression of coronary plaques, as observed in intravascular ultrasound-guided percutaneous coronary intervention studies. Moreover, the persistent, long-term high-density lipoprotein cholesterol elevation observed in the populations treated with pitavastatin is worthy of further attention. The reported improvements in lipid profiles are consistent among the studies conducted in Japan, Korea, Thailand, and Europe. In light of accumulating clinical experience worldwide, pitavastatin is now expected to establish its position for preventing and treating cardiovascular disease
A quantum protocol to win the graph colouring game on all Hadamard graphs
This paper deals with graph colouring games, an example of pseudo-telepathy,
in which two provers can convince a verifier that a graph is -colourable
where is less than the chromatic number of the graph. They win the game if
they convince the verifier. It is known that the players cannot win if they
share only classical information, but they can win in some cases by sharing
entanglement. The smallest known graph where the players win in the quantum
setting, but not in the classical setting, was found by Galliard, Tapp and Wolf
and has 32,768 vertices. It is a connected component of the Hadamard graph
with . Their protocol applies only to Hadamard graphs where
is a power of 2. We propose a protocol that applies to all Hadamard graphs.
Combined with a result of Frankl, this shows that the players can win on any
induced subgraph of having 1609 vertices, with . Combined with a
result of Frankl and Rodl, our result shows that all sufficiently large
Hadamard graphs yield pseudo-telepathy games.Comment: 5pag
Experimental demonstration of entanglement assisted coding using a two-mode squeezed vacuum state
We have experimentally realized the scheme initially proposed as quantum
dense coding with continuous variables [Ban, J. Opt. B \textbf{1}, L9 (1999),
and Braunstein and Kimble, \pra\textbf{61}, 042302 (2000)]. In our experiment,
a pair of EPR (Einstein-Podolski-Rosen) beams is generated from two independent
squeezed vacua. After adding two-quadrature signal to one of the EPR beams, two
squeezed beams that contain the signal were recovered. Although our squeezing
level is not sufficient to demonstrate the channel capacity gain over the
Holevo limit of a single-mode channel without entanglement, our channel is
superior to conventional channels such as coherent and squeezing channels. In
addition, optical addition and subtraction processes demonstrated are
elementary operations of universal quantum information processing on continuous
variables.Comment: 4 pages, 4 figures, submitted to Phys. Rev.

Compressibility of Liquefied Sand
Laboratory measurement using CCD camera was conducted to trace the sedimentation process of sand grains in a liquefied model layer. The purpose of this measurement was basically intended to obtain a visual evidence of appearance of suspended state in upper part of the liquefied soil. For this purpose, glass bead particles were used as model ground material. The test results prevailed that the glass bead grains were suspended in pore water at the instant when complete liquefaction was brought about to the layer, then they began to settle in the water. The measured pore water kept high value until grains ceased moving. And the moving velocity was far slower than that estimated by Stokes equation for sedimentation of single particle. From these findings, a predicting method was proposed to obtain the compressibility of liquefied sand layer and the continuation time of suspended state of grains
Omental leiomyosarcoma with unusual giant cells in a Beagle dog — Short communication
A 10-year-old castrated male Beagle dog was presented with a 2-month history of intermittent vomiting and abdominal pain. The dog was referred to the Veterinary Teaching Hospital at Iwate University for further evaluation, and a splenic tumour was suspected on the basis of ultrasonography and computed tomography. Surgery identified a large, solid, light-pink mass on the greater omentum with blood-coloured ascites in the abdominal cavity, and resection was performed. Microscopically, the mass comprised spindle-shaped tumour cells and scattered osteoclast-like giant cells. Most spindle-shaped cells were positive for vimentin, desmin, and smooth muscle actin (α-SMA), whereas osteoclast-like giant cells were positive only for vimentin. On the basis of histopathological and immunohistochemical findings, a diagnosis of leiomyosarcoma was made. To the best of our knowledge, this represents the first report of leiomyosarcoma associated with osteoclast-like giant cells developing from the greater omentum in a dog
